    Beschreibung: This open access book explores the intersection of property law, relocation, and resettlement processes in the United States and among communities that grapple with migration as an adaptation strategy. As communities face the prospect of relocating because of rising seas, policy makers, disaster specialists, and community leaders are scrambling to understand what adaptation pathways are legally possible. While in its ideal application, law functions blindly and without variation, the authors find that legal contradictions come to bear on resettlement processes and place certain communities further in harm’s way. This book will unearth these contradictions in order to understand why successful community-based resettlement has presented such a challenge to communities that are experiencing increasing land deterioration as a result of climate change.

    Beschreibung: History from the Bottom Up and the Inside Out James R. Barrett rethinks the boundaries of American social and labor history by investigating the ways in which working-class, radical, and immigrant people's personal lives intersected with their activism and religious, racial, ethnic, and class identities. Concerned with carving out space for individuals in the story of the working class, Barrett examines all aspects of individuals' subjective experiences, from their personalities, relationships, and emotions to their health and intellectual pursuits. Barrett's subjects include American communists, "blue-collar cosmopolitans"—such as well-read and well-traveled porters, sailors, and hoboes—and figures in early twentieth-century anarchist subculture. He also details the process of the Americanization of immigrant workers via popular culture and their development of class and racial identities, asking how immigrants learned to think of themselves as white. Throughout, Barrett enriches our understanding of working people’s lives, making it harder to objectify them as nameless cogs operating within social and political movements. In so doing, he works to redefine conceptions of work, migration, and radical politics.

    Beschreibung: Aquaculture for human consuming species is being considered as the first substitution of catching aquatic species due to increase of human population and decrease of wild aquatic stocks. In this study, the hybrid sturgeon Bester (female beluga x male sterlet) was produced for the first time in Iran. Sperm of 1.35 kg male Acipenser ruthenus was used to fertilize the eggs of 125 kg female Huso huso in Shahid Marjani Sturgeon propagation center (Agh Ghala, Golestan province). The fries of bester and control treatment of beluga were transported to International Sturgeon Research Institute (Rasht) after about one month by reaching to 490 mg and 377 mg of weight respectively. All fishes fed by artificial concentrated food (48-50% protein and 15-17% fat) after a period of feeding with Artemia and Daphnia. Sorting was carried out according to increase of fish weight for both fishes. Results showed that the imported sterlet spawners were not at the high maturation stages and especially the males had not suitable sperm quality. It showed that up to 2 months of age , these was no significant difference between bester and beluga weight but from this age up to 2 months of age the weight of beluga was greater. Meanwhile from 2 months old up to the end of the study (21 months) the weight of bester sample was significantly greater than beluga. The comparison of FCR for the whole rearing period showed no difference between bester and beluga (2.4 and 2.3 respectively). In general, the increase and decrease pattern of GR and SGR were coincided to each other, but showed monthly differences. Growth rate (GR) and specific growth rate (SGR) of bester were greater than beluga from 4th and 3rd month of rearing period respectively.

    Beschreibung: The most important habitats of mudskippers are muddy areas in tidal zone of tropical mangrove forests. Mudskippers are related to Oxudercinae subfamily of Gobiid fishes. Three most distributed species of Hormozgan mudskippers were Periophthalmus waltoni, Boleophthalmus dussumieri and Scartelaos tenuis. These fishes can be considered as euryhaline and eurythermal aquatic species, because they can tolerate a wide range of salinity and temperature. A research was done since september 2008 to september 2009 in two important mangrove regions of Hormuzgan (Tyab and Khamir) to determine some ecological characteristics of inhabited mudskipper species. Results showed that nitrate levels are significantly different between tidal lines and seasons (P〈0.05). Maximum nitrite concentrations were recorded 53.2 and 92.5 µg/l in Khamir and Tyab respectively. The annual correlation matrix showed that a positive correlation between phosphate concentration and nitrite and silicate (P〈0.05). Silicate concentration was very high, because of too low density of diatoms and radiolarians. Some species of diatoms, dinoflagellates, cyanobacteria and larvae of crustacea and echinoderms were observed with different density and diversity. Sediment composition of the studied areas were categorized in three classes (clay, sand and clay - sand). Polychaetes formed dominant group of benthic fauna in Tyab and Khamir areas. High density of capitellid worms was possibly related to some environmntal stress caused by activity of fishing and cargo vessels. It was not observed significant difference between fishes length in two areas (P〈0.05); Mean lengths of P. waltoni, B. dussumieri and S. tenuis were calculated 9.85, 14.7 and 11.5 cm respectively. Spawning period of each three species in both areas were obtained from late winter to late spring based on gonadosomatic index values. Male to female sex ratio of P. waltoni, B. dussumieri and S. tenuis were calculated 1:0.45, 1:0.41and 1:0.74 respectively. Absolute fecundity of P. waltoni, B. dussumieri and S. tenuis were estimated 3558 ± 2202, 3952 ± 1030 and 6742 ± 1939 respectively. P. waltoni feeds mainly on fiddler crab, S. tenuis uses crustaceans and gastropods and B. dussumieri has a vegetarian diet.

    Beschreibung: Biological characteristics of Liza klunzingeri were studied in two coastal areas, Sajaphi and Bahrekan, of eastern Khuzestan during March to February 2007. Among total 1880 measured fish specimens, 947 specimens were analyzed. The mean value of Gonado-somatic Index (GSI) for the male and female fish were calculated as 0.96± 1.39 and 3.25 ± 3.26 respectively. The GSI value was highest in November and lowest in July. The mean value of condition factor (K) was 1.25± 0.14 in male and 1.21± 0.15 for female. The highest K value were observed in June and the lowest value in February. The lenght at first maturity regardless of sexuality, was found to be 14.5 cm and the time of spawning based on reproduction pattern were determined in Nov- Dec. The length-weight relationship were calculated as Y=0.024L^2.76 (n=226R2=0.72) for males, Y=0.011L^3.00 (n=444R2= 0.78) for females and Y=0.0208L^2.82 (n=670R2 =0.82) for total fishes and also it’s found significant in level length weight relationship in (P〈0.05). According to biological characteristics and referring to American fisheries society (AFS) indices and Fuzzy logic expert system, Lize klunzingeri is classified as low vulnerable species.

    Beschreibung: The biological aspects of Sepia pharaonis was studied during years 2006-07. The studied area restricted to the Bahrekan in Khouzestan province covering the depths of 2 up to 25m. The sampling methods were gillnet and bottom trawl. A total of 310 specimens collected, of which there wasn’t found any cuttlefish in the study area from July to October (5 months). The collected samples were transferred to the laboratory ashore for further biological measurements consist of: Mantle length, Body weight, sex determination. Gonado-Somatic Index, and determination of Spermatophoric Index, Spawning season, Food preference, Maturity stages and chemical analysis for food value determination. The results showed that the overall sex ratio is about M:F= 2:1 with percentage of 67.41% for males and 32.50% for females. Males are significantly bigger than females with average mantle length (ML) of 233.3 and 269.3 mm for female and male, respectively; with body weight of 1102.3 and 1450.6 g. The mantle length body weight relationship was found W=0.001 ML 2.540 (R2= 0.92) Female as: W= 0.0015 ML 4797 (R2= 0.93) male From point of feeding, the food preferences results indicated that fish is considered as main food, crabs as minor food and other marine organisms such as bivalvia and gastropods as random food. The highest vacuity Index (CV) and empty stomachs was determined for March-April and the lowest value was is December. Also, the maximum GSI was estimated for March-April months in which showing coherrances with the lowest food preference. The maximum spermatophoricfilaments were 856 and 45 for male pharaoh cuttlefish with mantle length of 300 and 185 mm, and on the other hand this values for fecundity were estimated 1589 and 53 for female specimens with 254 and 198 mm mantle length. The spawning season occurs in April- March in which accompany with migration of pharaoh cuttlefish towards shallow waters. The fishing season would be in this period in w.

    Beschreibung: The present study was firstly conducted to study the rate of sexual maturity in Nereis diversicolor under suitable conditions of temperature and photoperiod. The second objective was to determine the potential of artificial breeding in these worms for mass culture. Nereis diversicolor worms were collected from the Anzali lagoon in 4000 sampling operations during the year’s 2004 to 2006 using Ekman grab with a surface area of 400 cm2. The water salinity, temperature and total organic matter (TOM) of sediments in the sampling region was recorded. The worms were maintained in 0.5 tons (1 x 1 m^2) tanks containing clayey-muddy sediment to a height of 20 cm covered with 10 cm water (5 ‰) until they reached a weight of 200-300 mg. Sexual maturity in this species was attained at 4-6 ºC and spawning occurred at approximately 16 ºC. The first gametes were observed five weeks after the temperature increased from 6 to 16 ºC. Sexual maturity was studied at various salinities (0.5, 5, 12, and 15 ‰). Results indicate that these worms attained earlier sexual maturity at salinity of 15 ‰, compared to other salinities studied. No significant differences (P〉0.05) were observed between sexual maturity attained at 12 ‰ and 15 ‰. Stocking density (20, 50, 100, 150 worms) was studied in terms of sex and showed that number of females were higher than males and the ratio was 11:1 (female: male). No significant differences (P〉0.05) were observed between the various stocking densities and their replicates. The effect of light and photoperiod in synchronizing reproduction in male and female N. diversicolor was studied. It was evident that reproduction behavior in adult worms increased for a period of one week at the end of each month after they are exposed to a prolonged photoperiod (L:D=16:8) followed by a period of dim light (simulated using 1 W lamps). Feeding trials were carried out with Saccharomyces cerevisiae, formulated fish diets and humus. Results showed that this diet was effective in speeding up sexual maturity in worms and significant effect of treatment was observed (P〈0.05) in worms fed a diet of humus alone. Eggs and sperms were fertilized and worms developed from the young monotrochophore with jelly layer to the trochophore larvae.

    Beschreibung: This study was aimed to investigate the effects of different doses of two hormones and an anti-aromatase, i.e. 17a methyl testosterone (MT), methyl di hydrotestosterone (MDHT) or mestanolone and letozole in masculinization of Nile tilapia (Oreochromis niloticus) under the condition of brackish water in Bafgh station situated in Yazd province in center of Iran. Each experiment in this study was consisted of 5 treaments with 3 replicates each. A number of 1725 larvaes was distributed randomly among 15 replicates at the beginning of each experiment. Each experiment lasted 45 days and the larvaes were reared in aerated flow-through pots and fiberglass tanks filled with brackish water. The averages for temperature, salinity, pH and dissolved oxygen of water were 26.9 ê, 8 g/l, 7.6 and 5.78% respectively during this study. In experiment 1, three different doses of 40, 60 and 100 mg MT/k of feed were fed to different groups of 7 day post fertilization (dpf) larvaes for 45 days from the beginning of the experiment. The results showed that the larvaes in 40 mg group were 100 percent masculinized based on squash test performed at the end of the experiment but masculinization rates of those in 60 and 100 mg groups were 99.7 and 96.2 perecent respectively. Based on Dunkan test, total body length and weight averages measured in biometry 3 (at the end of the experiment) were not significantly different among groups but in biometry 2 (30 days after the beginning of experiment), they were significantly lesser only in 40 mg group (P〈0.05). There was significant differences in survival rate of different groups of larvaes in this experiment based on chi-square test (χ=31.166, P〈0.05) and the values in 40 and 100 mg groups (74.5 and 82.9% respectively) were lesser than those in 60 mg, control 1 and control 2 groups (84.3, 89.0 and 87.0 respectively). In experiment 2, masculinization rates of two different groups of larvaes immersed in 1800 µg MDHT/liter once in 10dpf and twice in 10 and 14dpf were 80.0 and 91.9 percent respectively. There were no significant differences in total body length and weight averages measured in biometry 2 between different groups but significant differences were observed in total body length only in biometry 3 (P〈0.05) where the highest values occurred in experiment 1 and control 1 groups and the lowest one in experiment 2. Significant differences observed in survival rate of different groups of larvaes in this experiment based on chi-square test (χ=15.165, P〈0.05) and the rates in experiment 1, control 2 and 3 groups (89.9, 86.4 and 89.9% respectively) were higher than those in experiment 2 and control 1 groups (82.0 and 82.3 respectively). In experiment 3, three different doses of anti-aromatse letrozole (200, 300 and 400 mg/k feed) were fed to different groups of 7 day post fertilization (dpf) larvaes for 45 days from the beginning of the experiment. The larvaes in 400 group .were all masculinized whereas the masculinization rates in 200 and 300 mg groups were 99.0 and 99.6% respectively. There were significant differences in total body length and weight averages measured in biometry 2 and 3 among groups in this experiment (P〈0.05) where the highest and the lowest values occurred in control 2 and experime2 groups respectively. Based on chi-square, the survival rate of different groups was significantly different (χ=41.119, P〈0.05) and the lowest rate occurred in experiment 2 group. No significant differences observed in gender ratios within all control groups in this study based on chi-square test. According to the findings acquired under the condition of brackish water at the present study, it would be potentially recommended to use MT and letrozole for the production of all male populations of Nile tilapia fish in order to provide fish farmers with no harmful environmental impacts on water sources in rivers and seas which occured due to the uncontroled breeding of tilapia. However, more research is needed to draw firm conclusions to use hormones and in especial anti-aromase letrozole because of the shortage of sufficient data in current references.

    Beschreibung: During last 65 years the catch of mullets had increasing trends with some fluctuations in the Iranian coastal water of the Caspian Sea .In this period about 138 thousand tons of mullets have been caught. Mullet’s account for 35% of total catch annually .In recent years species composition of mullets has chanched in the Iranian coastal water of the Caspian Sea and catch composition of golden grey mullet increased from 76% in 1995 to 98% in 2006. In this survey some biological characteristics of golden grey mullet have been studied in Iranian coastal water of the Caspian Sea .Fish samples have been gathered from commercial catch of beach seine cooperatives monthly in Iranian coastal water of the Caspian Sea over 2006 and 2007. In the laboratory fishes have been measured biometrically and biological parameters have been calculated .Also catch statistics of mullets during 2006-2007 have been obtained and discussed. Results showed that the catch of mullets in beach seine cooperatives during 2006 and 2007 was 4181 and 3685 tons respectively that golden grey mullet contribute 99% and 98% of the catch composition of mullets respectively. Length range of golden grey mullet caught by beach seine cooperatives was 19-50.2 cm with mean length of 32.7 ± 6.4 (± SD) and weight range was 67-1475 gr with mean weight of 411 ± 255 gr. The age structure of this species was comprised 2-10 years old fish with mean age of 4.42 years old. In this survey totally the sex ratio of male: female of golden grey mullet was 356: 434 that was significant variation from equal sex ratio. Pick of the spawning in Guilan province was in October and in Mazandaran and Golestan provinces was in November. In October the proportion of spawning females declined from western area (Guilan province) towards eastern parts (Golestan province).The highest proportion of spawning females was in December in Golestan province. The highest GSI index value was observed in September and October and it was decreased in November and December and it was consistent during January till April. The mean absolute fecundity was 700881±429987 eggs with minimum and maximum fecundity of 200112 and 2282862 eggs respectively. The Lm 50% for female golden grey mullet was calculated as 33.6 cm.

    Beschreibung: The Kutum, Rutilus frisii kutum, is one of the most important bony fishes in Iranian coastal of Caspian Sea. Its harvest range is between 9000-10000 tons in a year, nearly 60% of the income of Bony fish fishery produced by kutum fishery. The stock of this species reduced drastically in 1982 and the catch slumped to the less than 250 tons in a year. Kutum spawning grounds deterioration, illegal catch, and lack of restocking program were the main cause of the decline. This Spices in nature comprised by two distinct form, autumn and spring form. It is worth to be mentioned, by the effect of Caspian Sea Bony fishes Research Center s experts in 1983, artificial spawning and releasing the fries to the sea were commenced and the catch steadily improved. But all activities concerning restocking of kutum concentrated in spring form, as at present about 260 million its fries are released into sea for restocking by Iranian Fisheries Organization, but for above reasons and lack of restocking program, the populations of autumn form gravely shrinked and neared to be extinct. Therefore, to enhance the biodiversity and boost fishers livelihood of kutum in Caspian Sea this project implemented by cooperation of Iranian Fisheries Organization (IFRO) and Caspian Environment Program (CEP) in Aquaculture Institute (Inland Waters). In this project, brooders caught from Anzali lagoon and maintained in two different condition, include of floating cages in Anzali lagoon and earthen ponds in Sefidrud Fisheries Research Station. The results showed that there weren’t significant differences between two maintenance statuses in maturation period and other reproductive characteristics of brooders. The ratio of male to female was 1 to 1.4. Minimum and maximum weight measured 1450 to 3100 g (with average of 1850 g) in female and 670 to 1900 g (with average of 1165 g) in male, respectively. The first natural spawning of brooders occurred in the end of January in temperature of 8 till 10 °C in concrete ponds. Also, some of maintained brooders in earthen ponds spawned in February. The average number of absolute, function and relative fecundity determined 88565 16809, 73805 14008 and 48670 12056, respectively. For artificial spawning, male and female brooders injected by pituitary gland with dose of 2-3 and 4-5 mg/kg body weight, respectively. Approximately, 10 and 8 present of female were over-ripe and immature in March (artificial spawning time), respectively. More than 59 % of injected female brooders induced to spawning in first stage after 10-12 hours and 13 % of them in twice stage and 7-8 hours after first stage. And also, 27.6% of females didn’t positive response to injection. Dry method used for eggs fecundity and incubation period lasted 7- 10 days in 14-16 °C. In totally, eggs fertilization were more than 95% and the average of eggs fertilization percent in throughout of period measured more than 92.7 6 %. Eyed eggs appearance occurred 3 days after fecundity and its mean was 92.7 15.1%. Larvae after yolk sac absorption feed with dry milk for 4-5 days and then introduced into fertilized earthen ponds (500 m2 and equipped to aerators) in intensive condition and fed with micro pellet food for 3-4 month. In finally, more than 1.8 million fries of 1-2 g and some more than 5 g produced and released into Anzali lagoon to its restocking for first time. It is expected that continuing of restocking process of autumn form kutum by Iranian Fisheries Organization eventuate to population increasing of this form in Caspian Sea in future.

    Beschreibung: Due to the usefulness of shrimp broodstock pelleted diets, from aspects of, easier maintenance, transportation, broodstock feeding, and cheaper as compared to natural wet diets, the use of natural wet foods, include sand worm (Perinereis nuntica), cattle fish )Sepia pharaonis) and veal livier decreased and the quantity of pelleted diet increased. Survey was conducted, in tankes with a volume of 300 liters. Tanks were filled with 150 liters of water. 10 broodstock in each tank was left, with an average weight of 37±2 grams. Daily feeding rate, was twenty-five percent of their biomass. The survey was include, 9 treatments with 3 replicates in each tank as described below. Control treatment: broodstock feeding only with, sand worm (33%), cattle fish (34%) and bull livier (33%). Exprimental treatment 1: broodstock feeding with pelleted diet contain 50 percent crude protein and 8 percent crude fat (50%)+sand worm (16 %)+cattle fish (18%)+veal livier (16%). Treatment 2: broodstock feeding with pelleted diet contain 50 percent crude protein and 10 percent crude fat (50 %)+sand worm (16 %)+cattle fish (18%) and veal livier (16%). Treatment 3: broodstock feeding with pelleted diet contain 40 percent crude protein and 10 percent crude fat (50%)+sand worm (16 %)+cattle fish (18 %) and veal livier (16 %). Treatment 4: broodstock feeding with pelleted diet contain 40 percent crude protein and 8 percent crude fat (50 %)+sand worm (16 %)+cattle fish (18 %) and veal livier (16 %). Treatment 5: broodstock feeding with pelleted diet contain 50 percent crude protein and 10 percent crude fat (100 %). Treatment 6: broodstock feeding with pelleted diet contain 50 percent crude protein and 8 percent crude fat (100 %). Treatment 7: broodstock feeding with pelleted diet contain 40 percent crude protein and 10 percent crude fat (100 %). Treatment 8: broodstock feeding with pelleted diet contain 40 percent crude protein and 8 percent crude fat (100%). The results showed that, Gonadosomatic index (GSI) in treatments 3: control and 6, was significantly more than others treatments (p〈0.05). Hepatosomatic indexes, in often treatments was almost equal, and in some cases were significantly different (p〈0.05). In treatments 3 and control, absolute fecundity, was significantly more than others treatment (p〈0.05). The survival percent, in treatment 8 was significantly less than others treatments (p〈0.05). The survival percent in others treatments was not significantly difference (p〉0.05). From the aspect of mean weight of broodstock, wasn’t significant difference in treatments (p〉0.05). From the aspect of mean length of carapac, wasn’t significant difference in treatments (p〉0.05). From the aspect of mean body length, wasn’t significant difference in often treatments (p〉0.05), and in treatments 5 and 6 was significantly less than others (p〈0.05). In the determination of relasheship between kind of treatments and abundance of maturated broodsock, wasn’t significantly difference (p〉0.05). In the determination of, correlation between weight (g) and total length(cm), (r=0.71), weight and carapace length (cm) (r=0.70), the correlation was strong. Between GSI, HIS, carapace length and total length the correlation was intermediate (r=0.54). The correlation between absolutely fecundity and total length (r=0.20), absolutely fecundity and carapace length (r=0.28), absolutely fecundity and weight (r=0.35) was weak. The results showed that, the use of combination of pelleted diet and natural wet diets can increase female maturation indexes. Totally we can noted that, GSI, HIS and absolute fecundity of broodstock, that fed with pelleted diet contain 40 percent crude protein and 10 percent crude fat (50 %)+sand worm (16 %)+cattle fish (18 %) and veal livier (16 %) (treatment 3) was better than the other treatments. Positive effects of this treatnent on sexual indexes, was due to provide part of nutritional requirement of shrimp broodstock from pelleted diet.

    Beschreibung: In 'An Aqueous Territory' Ernesto Bassi traces the configuration of a geographic space he calls the transimperial Greater Caribbean between 1760 and 1860. Focusing on the Caribbean coast of New Granada (present-day Colombia), Bassi shows that the region's residents did not live their lives bounded by geopolitical borders. Rather, the cross-border activities of sailors, traders, revolutionaries, indigenous peoples, and others reflected their perceptions of the Caribbean as a transimperial space where trade, information, and people circulated, both conforming to and in defiance of imperial regulations. Bassi demonstrates that the islands, continental coasts, and open waters of the transimperial Greater Caribbean constituted a space that was simultaneously Spanish, British, French, Dutch, Danish, Anglo-American, African, and indigenous.

    Beschreibung: In Uneven Encounters, Micol Seigel chronicles the exchange of popular culture between Brazil and the United States in the years between the World Wars, and demonstrates how that exchange affected ideas of race and nation in both countries. From Americans interpreting advertisements for Brazilian coffee or dancing the Brazilian maxixe, to Rio musicians embracing the “foreign” qualities of jazz, Seigel traces a lively, cultural back and forth. Along the way, she shows how race and nation for both elites and non-elites are constructed together, and driven by global cultural and intellectual currents as well as local, regional, and national ones. Seigel explores the circulation of images of Brazilian coffee and of maxixe in the United States during the period just after the imperial expansions of the early twentieth century. Exoticist interpretations structured North Americans’ paradoxical sense of themselves as productive “consumer citizens.” Some people, however, could not simply assume the privileges of citizenship. In their struggles against racism, Afro-descended citizens living in Rio de Janeiro, São Paulo, New York, and Chicago encountered images and notions of each other, and found them useful. Seigel introduces readers to cosmopolitan Afro-Brazilians and African Americans who rarely traveled far from home but who nonetheless absorbed ideas from abroad. She suggests that studies comparing U.S. and Brazilian racial identities as two distinct constructions are misconceived. Racial formation transcends national borders; attempts to understand it must do the same.

    Beschreibung: The goal of this book is simple: We would like to show how mortality dynamics can be visualized in the so-called Lexis diagram. To appeal to as many potential readers as possible, we do not require any specialist knowledge. This approach may be disappointing: Demographers may have liked more information about the mathematical underpinnings of population dynamics on the Lexis surface as demonstrated, for instance, by Arthur and Vaupel in 1984. Statisticians would have probably preferred more information about the underlying smoothing methods that were used. Epidemiologists likewise might miss discussions about the etiology of diseases. Sociologists would have probably expected that our results were more embedded into theoretical frameworks....

    Beschreibung: Since the late 1990s, Asian nations have increasingly encouraged, facilitated, or demanded the return of emigrants. In this interdisciplinary collection, distinguished scholars from countries around the world explore the changing relations between nation-states and transnational mobility. Taking into account illegally trafficked migrants, deportees, temporary laborers on short-term contracts, and highly skilled émigrés, the contributors argue that the figure of the returnee energizes and redefines nationalism in an era of increasingly fluid and indeterminate national sovereignty. They acknowledge the diversity, complexity, and instability of reverse migration, while emphasizing its discursive, policy, and political significance at a moment when the tensions between state power and transnational subjects are particularly visible. Taken together, the essays foreground Asia as a useful site for rethinking the intersections of migration, sovereignty, and nationalism.

    Beschreibung: Fear has long served elites. They rely on fear to keep and expand their privileges and control the masses. In the current crisis of the capitalist world system, elites in the United States, along with other central countries, promote fear of crime and terrorism. They shaped these fears so that people looked to authorities for security, which permitted extension of apparatuses of coercion like police and military forces. In the face of growing oppression, rebellion against elite hegemony remains possible. This book offers an analysis of the crisis and strategies for rebellion.

    Beschreibung: In the early twentieth century, Native American baskets, blankets, and bowls could be purchased from department stores, “Indian stores,” dealers, and the U.S. government’s Indian schools. Men and women across the United States indulged in a widespread passion for collecting Native American art, which they displayed in domestic nooks called “Indian corners.” Elizabeth Hutchinson identifies this collecting as part of a larger “Indian craze” and links it to other activities such as the inclusion of Native American artifacts in art exhibitions sponsored by museums, arts and crafts societies, and World’s Fairs, and the use of indigenous handicrafts as models for non-Native artists exploring formal abstraction and emerging notions of artistic subjectivity. She argues that the Indian craze convinced policymakers that art was an aspect of “traditional” Native culture worth preserving, an attitude that continues to influence popular attitudes and federal legislation. Illustrating her argument with images culled from late-nineteenth- and early-twentieth-century publications, Hutchinson revises the standard history of the mainstream interest in Native American material culture as “art.” While many locate the development of this cross-cultural interest in the Southwest after the First World War, Hutchinson reveals that it began earlier and spread across the nation from west to east and from reservation to metropolis. She demonstrates that artists, teachers, and critics associated with the development of American modernism, including Arthur Wesley Dow and Gertrude Käsebier, were inspired by Native art. Native artists were also able to achieve some recognition as modern artists, as Hutchinson shows through her discussion of the Winnebago painter and educator Angel DeCora. By taking a transcultural approach, Hutchinson transforms our understanding of the role of Native Americans in modernist culture.

    Beschreibung: Presenting an unprecedented, integrated view of migration in North America, this interdisciplinary collection of essays illuminates the movements of people within and between Canada, the Caribbean, Mexico, and the United States over the past two centuries. Several essays discuss recent migrations from Central America as well. In the introduction, Dirk Hoerder provides a sweeping historical overview of North American societies in the Atlantic world. He also develops and advocates what he and Nora Faires call “transcultural societal studies,” an interdisciplinary approach to migration studies that combines migration research across disciplines and at the local, regional, national, and transnational levels. The contributors examine the movements of diverse populations across North America in relation to changing cultural, political, and economic patterns.

    Beschreibung: In DISCIPLINARY CONQUEST, Ricardo Salvatore argues that the foundation of the discipline of Latin American studies, pioneered between 1900 and 1945, was linked to the United States’s business and financial interests and informal imperialism. In contrast, the consolidation of Latin American studies has traditionally been placed in the 1960s, as a reaction to the Cuban Revolution. Focusing on five representative U.S. scholars of South America—historian Clarence Haring, geographer Isaiah Bowman, political scientist Leo Rowe, sociologist Edward Ross, and archaeologist Hiram Bingham -- Salvatore demonstrates how their search for comprehensive knowledge about South America can be understood as a contribution to hemispheric hegemony, an intellectual conquest of the region. U.S. economic leaders, diplomats, and foreign-policy experts needed knowledge about the region to expand investment and trade, as well as the U.S.’s international influence

    Beschreibung: 'Thinking Literature across Continents' finds Ranjan Ghosh and J. Hillis Miller—two thinkers from different continents, cultures, training, and critical perspectives—debating and reflecting upon what literature is and why it matters. Ghosh and Miller do not attempt to formulate a joint theory of literature; rather, they allow their different backgrounds and lively disagreements to stimulate generative dialogue on poetry, world literature, pedagogy, and the ethics of literature. Addressing a varied literary context ranging from Victorian literature, Chinese literary criticism and philosophy, and continental philosophy to Sanskrit poetics and modern European literature, Ghosh offers a transnational theory of literature while Miller emphasizes the need to account for what a text says and how it says it. This book highlights two minds continually discovering new paths of communication and two literary and cultural traditions intersecting in productive and compelling ways.

    Beschreibung: Between 1750 and 1870 the world faced transformations marked by the rise of industrial capitalism, the fall of European empires in the Americas, and the rise of nations there. 'New Countries' explores how these events transformed the Americas in diverging ways. Up to 1790, Saint Domingue’s sugar and slave economy drove Atlantic trades; then revolutionary slaves made Haiti, freeing themselves and ending export production. New Spain’s silver fueled global trades until Bajío insurgents collapsed silver capitalism and undermined Spanish rule after 1810. The fall of silver left regions from Mexico through Guatemala and the Andes in search of new polities and economies. After 1870 the United States became an agro-industrial hegemon, most American nations turned to commodity exports, and Haitians and diverse indigenous peoples struggled to keep independent lives beyond the reach of industrial powers seeking supplies and markets.

    Beschreibung: From Skirts Ahoy! to M*A*S*H, Private Benjamin, G.I. Jane, and JAG, films and television shows have grappled with the notion that military women are contradictory figures, unable to be both effective soldiers and appropriately feminine. In Soldiers’ Stories, Yvonne Tasker traces this perceived paradox across genres including musicals, screwball comedies, and action thrillers. She explains how, during the Second World War, women were portrayed as auxiliaries, temporary necessities of “total war.” Later, nursing, with its connotations of feminine care, offered a solution to the “gender problem.” From the 1940s through the 1970s, musicals, romances, and comedies exploited the humorous potential of the gender role reversal that the military woman was taken to represent. Since the 1970s, female soldiers have appeared most often in thrillers and legal and crime dramas, cast as isolated figures, sometimes victimized and sometimes heroic. Soldiers’ Stories is a comprehensive ...

    Beschreibung: Chronicling the dramatic history of the Brazilian Amazon during the Second World War, Seth Garfield provides fresh perspectives on contemporary environmental debates. His multifaceted analysis explains how the Amazon became the object of geopolitical rivalries, state planning, media coverage, popular fascination, and social conflict. In need of rubber, a vital war material, the United States spent millions of dollars to revive the Amazon's rubber trade. In the name of development and national security, Brazilian officials implemented public programs to engineer the hinterland's transformation. Migrants from Brazil's drought-stricken Northeast flocked to the Amazon in search of work. In defense of traditional ways of life, longtime Amazon residents sought to temper outside intervention.

    Beschreibung: In Ruling Capital, Kevin P. Gallagher demonstrates how several emerging market and developing countries (EMDs) managed to reregulate cross-border financial flows in the wake of the global financial crisis, despite the political and economic difficulty of doing so at the national level. Gallagher also shows that some EMDs, particularly the BRICS coalition, were able to maintain or expand their sovereignty to regulate cross-border finance under global economic governance institutions. Gallagher combines econometric analysis with in-depth interviews with officials and interest groups in select emerging markets and policymakers at the International Monetary Fund, the World Trade Organization, and the G-20 to explain key characteristics of the global economy.

    Beschreibung: A NATION ON THE LINE is an ethnographic study of the call center industry in the Philippines and of its workforce composed of young, largely college-educated Filipinos. Padios merges several lines of inquiry about Pacific transnationalism, about the role of affective labor in global markets, and about critique of Filipino exploitation by the United States through economic and military power since independence-- in order to consider how post-colonial and post-industrial changes in the Philippines’ role in global capitalism and culture are brought to bear in everyday life. Padios argues that the call center industry serves as a rich case-study for how Filipinos work within hegemonic dynamics of relational service and an understanding of American consumer culture in ways that figure Filipinos' sense of identity and aspirations at the national and individual levels.

    Beschreibung: Published in cooperation with the William P. Clements Center for Southwest Studies, Southern Methodist University. In Land of Necessity, historians and anthropologists unravel the interplay of the national and transnational and of scarcity and abundance in the region split by the 1,969-mile boundary line dividing Mexico and the United States. This richly illustrated volume, with more than 100 images including maps, photographs, and advertisements, explores the convergence of broad demographic, economic, political, cultural, and transnational developments resulting in various forms of consumer culture in the borderlands. Though its importance is uncontestable, the role of necessity in consumer culture has rarely been explored. Indeed, it has been argued that where necessity reigns, consumer culture is anemic. This volume demonstrates otherwise. In doing so, it sheds new light on the history of the U.S.-Mexico borderlands, while also opening up similar terrain for scholarly inquiry into consumer culture. The volume opens with two chapters that detail the historical trajectories of consumer culture and the borderlands. In the subsequent chapters, contributors take up subjects including smuggling, tourist districts and resorts, purchasing power, and living standards. Others address home décor, housing, urban development, and commercial real estate, while still others consider the circulation of cinematic images, contraband, used cars, and clothing. Several contributors discuss the movement of people across borders, within cities, and in retail spaces. In the two afterwords, scholars reflect on the U.S.-Mexico borderlands as a particular site of trade in labor, land, leisure, and commodities, while also musing about consumer culture as a place of complex political and economic negotiations. Through its focus on the borderlands, this volume provides valuable insight into the historical and contemporary aspects of the big “isms” shaping modern life: capitalism, nationalism, transnationalism, globalism, and, without a doubt, consumerism.

    Beschreibung: In this book, we discuss the changing medical and public profile of fungal infections in the period 1850–2000. We consider four sets of diseases: ringworm and athlete’s foot (dermatophytosis); thrush or candidiasis (infection with Candida albicans); endemic, geographically specific infections in North America (coccidioidomycosis, blastomycosis and histoplasmosis) and mycotoxins; and aspergillosis (infection with Aspergillus fumigatus). We discuss each disease in relation to developing medical knowledge and practices, and to social changes associated with ‘modernity’. Thus, mass schooling provided ideal conditions for the spread of ringworm of the scalp in children, and the rise of college sports and improvement of personal hygiene led to the spread of athlete’s foot. Antibiotics seemed to open the body to more serious Candida infections, as did new methods to treat cancers and the development of transplantation. Regional fungal infections in North America came to the fore due to the economic development of certain regions, where population movement brought in non-immune groups who were vulnerable to endemic mycoses. Fungal toxins or mycotoxins were discovered as by-products of modern food storage and distribution technologies. Lastly, the rapid development and deployment of new medical technologies, such as intensive care and immunosuppression in the last quarter of the twentieth century, increased the incidence of aspergillosis and other systemic mycoses.

    Beschreibung: In 'Dying in Full Detail' Jennifer Malkowski explores digital media's impact on one of documentary film's greatest taboos: the recording of death. Despite technological advances that allow for the easy creation and distribution of death footage, digital media often fail to live up to their promise to reveal the world in greater fidelity. Malkowski analyzes a wide range of death footage, from feature films about the terminally ill (Dying, Silverlake Life, Sick), to surreptitiously recorded suicides (The Bridge), to #BlackLivesMatter YouTube videos and their precursors. Contextualizing these recordings in the long history of attempts to capture the moment of death in American culture, Malkowski shows how digital media are unable to deliver death "in full detail," as its metaphysical truth remains beyond representation.

    Beschreibung: Human rights advocates have long pressed for international institutions to prosecute crimes against humanity. With its global reach and mandate to investigate and prosecute some of the world's most severe crimes (genocide, war crimes, and crimes against humanity) the creation of the International Criminal Court in 2002 was hailed as a landmark event in the evolution of truly global society. Supporters argue that the ICC and other transnational tribunals will deter the commission of atrocities and contribute to global peace and stability, and they laud its independence and its potential to check the arbitrary use of power against the powerless. To better understand how international criminal courts function and determine their broader implications for global society, this book examines the factors that led to the creation and evolution of international criminal courts, the nature of the support for and opposition to such institutions, and how they function.

    Beschreibung: Cuba's first republican era (1902–1959) is principally understood in terms of its failures and discontinuities, its first three decades and the overthrow of Machado seen at best as a prologue to the "real" revolution of 1959. This book brings together scholars from North America, Cuba, and Spain to challenge this narrative, presenting republican Cuba instead as a time of meaningful engagement—socially, politically, and symbolically. Addressing a wide range of topics—civic clubs and folkloric societies, science, public health and agrarian policies, popular culture, national memory, and the intersection of race and labor—the contributors explore how a broad spectrum of Cubans embraced a political and civic culture of national self-realization. These essays recast the first republic as a time of deep continuity in processes of liberal state- and nation-building that were periodically disrupted—but also reinvigorated—by foreign intervention and profound uncertainty.

    Beschreibung: Drawing on methods and approaches from anthropology, media studies, film theory, and cultural studies, the contributors to Media, Erotics, and Transnational Asia examine how mediated eroticism and sexuality circulating across Asia and Asian diasporas both reflect and shape the social practices of their producers and consumers. The essays in this volume cover a wide geographic and thematic range, and combine rigorous textual analysis with empirical research into the production, circulation, and consumption of various forms of media. Taken together, the essays offer fresh insights into research on gender, erotics, media, and Asia transnationally conceived. Contributors.

    Beschreibung: In Musicians in Transit Matthew B. Karush examines the transnational careers of seven of the most influential Argentine musicians of the twentieth century: Afro-Argentine swing guitarist Oscar Alemán, jazz saxophonist Gato Barbieri, composer Lalo Schifrin, tango innovator Astor Piazzolla, balada singer Sandro, folksinger Mercedes Sosa, and rock musician Gustavo Santaolalla. As active participants in the globalized music business, these artists interacted with musicians and audiences in the United States, Europe, and Latin America and contended with genre distinctions, marketing conventions, and ethnic stereotypes. By responding creatively to these constraints, they made innovative music that provided Argentines with new ways of understanding their nation’s place in the world.

    Beschreibung: Citizenship is often assumed to be a clear-cut issue - either one has it or one does not. However, as the contributors to Citizenship in Question demonstrate, citizenship is not self-evident; it emerges from often obscure written records and is interpreted through ambiguous and dynamic laws. In case studies that analyze the legal barriers to citizenship rights in over twenty countries, the contributors explore how states use evidentiary requirements to create and police citizenship, often based on fictions of racial, ethnic, class, and religious differences. Whether examining the United States’ deportation of its own citizens, the selective use of DNA tests and secret results in Thailand, or laws that have stripped entire populations of citizenship, the contributors emphasize the political, psychological, and personal impact of citizenship policies.

    Beschreibung: Most wars between countries end quickly and at relatively low cost. The few in which high-intensity fighting continues for years bring about a disproportionate amount of death and suffering. What separates these few unusually long and intense wars from the many conflicts that are far less destructive? In Logics of War, Alex Weisiger tests three explanations for a nation’s decision to go to war and continue fighting regardless of the costs. He combines sharp statistical analysis of interstate wars over the past two centuries with nine narrative case studies. He examines both well-known conflicts like World War II and the Persian Gulf War, as well as unfamiliar ones such as the 1864–1870 Paraguayan War (or the War of the Triple Alliance), which proportionally caused more deaths than any other war in modern history.

    Beschreibung: In What’s Left of the Left, distinguished scholars of European and U.S. politics consider how center-left political parties have fared since the 1970s. They explore the left’s responses to the end of the postwar economic boom, the collapse of the Soviet Union, the erosion of traditional party politics, the expansion of market globalization, and the shift to a knowledge-based economy. Their comparative studies of center-left politics in Scandinavia, France, Germany, southern Europe, post–Cold War Central and Eastern Europe, the United Kingdom, and the United States emphasize differences in the goals of left political parties and in the political, economic, and demographic contexts in which they operate. The contributors identify and investigate the more successful center-left initiatives, scrutinizing how some conditions facilitated them, while others blocked their emergence or limited their efficacy.

    Beschreibung: 'In We Dream Together' Anne Eller breaks with dominant narratives of conflict between the Dominican Republic and Haiti by tracing the complicated history of Dominican emancipation and independence between 1822 and 1865. Eller moves beyond the small body of writing by Dominican elites that often narrates Dominican nationhood to craft inclusive, popular histories of identity, community, and freedom, summoning sources that range from trial records and consul reports to poetry and song. Rethinking Dominican relationships with their communities, the national project, and the greater Caribbean, Eller shows how popular anticolonial resistance was anchored in a rich and complex political culture. Haitians and Dominicans fostered a common commitment to Caribbean freedom, the abolition of slavery, and popular democracy, often well beyond the reach of the state.

    Beschreibung: During last 65 years the catch of mullets had increasing trends with some fluctuations in the Iranian coastal water of the Caspian Sea .In this period about 138 thousand tons of mullets have been caught. Mullet’s account for 35% of total catch annually .In recent years species composition of mullets has chanched in the Iranian coastal water of the Caspian Sea and catch composition of golden grey mullet increased from 76% in 1995 to 98% in 2006. In this survey some biological characteristics of golden grey mullet have been studied in Iranian coastal water of the Caspian Sea .Fish samples have been gathered from commercial catch of beach seine cooperatives monthly in Iranian coastal water of the Caspian Sea over 2006 and 2007. In the laboratory fishes have been measured biometrically and biological parameters have been calculated .Also catch statistics of mullets during 2006-2007 have been obtained and discussed. Results showed that the catch of mullets in beach seine cooperatives during 2006 and 2007 was 4181 and 3685 tons respectively that golden grey mullet contribute 99% and 98% of the catch composition of mullets respectively. Length range of golden grey mullet caught by beach seine cooperatives was 19-50.2 cm with mean length of 32.7 ± 6.4 (± SD) and weight range was 67-1475 gr with mean weight of 411 ± 255 gr. The age structure of this species was comprised 2-10 years old fish with mean age of 4.42 years old. In this survey totally the sex ratio of male:female of golden grey mullet was 356: 434 that was significant variation from equal sex ratio. Pick of the spawning in Guilan province was in October and in Mazandaran and Golestan provinces was in November. In October the proportion of spawning females declined from western area (Guilan province) towards eastern parts (Golestan province).The highest proportion of spawning females was in December in Golestan province. The highest GSI index value was observed in September and October and it was decreased in November and December and it was consistent during January till April. The mean absolute fecundity was 700881 ± 429987 eggs with minimum and maximum fecundity of 200112 and 2282862 eggs respectively. The Lm 50% for female golden grey mullet was calculated as 33.6 cm.

    Beschreibung: The biological aspects of Sepia pharaonis was studied during years 2006-07. The studied area restricted to the Bahrekan in Khouzestan province covering the depths of 2 up to 25m. The sampling methods were gillnet and bottom trawl. A total of 310 specimens collected, of which there wasn’t found any cuttlefish in the study area from July to October (5 months). The collected samples were transferred to the laboratory ashore for further biological measurements consist of: Mantle length, Body weight, sex determination. Gonado-Somatic Index, and determination of Spermatophoric Index, Spawning season, Food preference, Maturity stages and chemical analysis for food value determination. The results showed that the overall sex ratio is about M:F= 2:1 with percentage of 67.41% for males and 32.50% for females. Males are significantly bigger than females with average mantle length (ML) of 233.3 and 269.3 mm for female and male, respectively; with body weight of 1102.3 and 1450.6 g. The mantle length body weight relationship was found W=0.001 ML 2.540 (R2= 0.92) Female as: W= 0.0015 ML 4797 (R2= 0.93) male From point of feeding, the food preferences results indicated that fish is considered as main food, crabs as minor food and other marine organisms such as bivalvia and gastropods as random food. The highest vacuity Index (CV) and empty stomachs was determined for March-April and the lowest value was is December. Also, the maximum GSI was estimated for March-April months in which showing coherrances with the lowest food preference. The maximum spermatophoricfilaments were 856 and 45 for male pharaoh cuttlefish with mantle length of 300 and 185 mm, and on the other hand this values for fecundity were estimated 1589 and 53 for female specimens with 254 and 198 mm mantle length. The spawning season occurs in April- March in which accompany with migration of pharaoh cuttlefish towards shallow waters. The fishing season would be in this period in w.

    Beschreibung: This study was aimed to investigate the effects of different doses of two hormones and an anti-aromatase, i.e. 17 methyl testosterone (MT), methyl di hydrotestosterone (MDHT) or mestanolone and letozole in masculinization of Nile tilapia (Oreochromis niloticus) under the condition of brackish water in Bafgh station situated in Yazd province in center of Iran. Each experiment in this study was consisted of 5 treaments with 3 replicates each. A number of 1725 larvaes was distributed randomly among 15 replicates at the beginning of each experiment. Each experiment lasted 45 days and the larvaes were reared in aerated flow-through pots and fiberglass tanks filled with brackish water. The averages for temperature, salinity, pH and dissolved oxygen of water were 26.9 ê, 8 g/l, 7.6 and 5.78% respectively during this study. In experiment 1, three different doses of 40, 60 and 100 mg MT/k of feed were fed to different groups of 7 day post fertilization (dpf) larvaes for 45 days from the beginning of the experiment. The results showed that the larvaes in 40 mg group were 100 percent masculinized based on squash test performed at the end of the experiment but masculinization rates of those in 60 and 100 mg groups were 99.7 and 96.2 perecent respectively. Based on Dunkan test, total body length and weight averages measured in biometry 3 (at the end of the experiment) were not significantly different among groups but in biometry 2 (30 days after the beginning of experiment), they were significantly lesser only in 40 mg group (P〈0.05). There was significant differences in survival rate of different groups of larvaes in this experiment based on chi-square test (χ=31.166, P〈0.05) and the values in 40 and 100 mg groups (74.5 and 82.9% respectively) were lesser than those in 60 mg, control 1 and control 2 groups (84.3, 89.0 and 87.0 respectively). In experiment 2, masculinization rates of two different groups of larvaes immersed in 1800 µg MDHT/liter once in 10dpf and twice in 10 and 14dpf were 80.0 and 91.9 percent respectively. There were no significant differences in total body length and weight averages measured in biometry 2 between different groups but significant differences were observed in total body length only in biometry 3 (P〈0.05) where the highest values occurred in experiment 1 and control 1 groups and the lowest one in experiment 2. Significant differences observed in survival rate of different groups of larvaes in this experiment based on chi-square test (χ=15.165, P〈0.05) and the rates in experiment 1, control 2 and 3 groups (89.9, 86.4 and 89.9% respectively) were higher than those in experiment 2 and control 1 groups (82.0 and 82.3 respectively). In experiment 3, three different doses of anti-aromatse letrozole (200, 300 and 400 mg/k feed) were fed to different groups of 7 day post fertilization (dpf) larvaes for 45 days from the beginning of the experiment. The larvaes in 400 group .were all masculinized whereas the masculinization rates in 200 and 300 mg groups were 99.0 and 99.6% respectively. There were significant differences in total body length and weight averages measured in biometry 2 and 3 among groups in this experiment (P〈0.05) where the highest and the lowest values occurred in control 2 and experime2 groups respectively. Based on chi-square, the survival rate of different groups was significantly different (χ=41.119, P〈0.05) and the lowest rate occurred in experiment 2 group. No significant differences observed in gender ratios whithin all control groups in this study based on chi-square test. According to the findings aquired under the condition of brackish water at the present study, it would be potentially recommended to use MT and letrozole for the production of all male polpulations of Nile tilapia fish in order to provide fish farmers with no harmful environmental impacts on water sources in rivers and seas which occured due to the uncontroled breeding of tilapia. However, more research is needed to draw firm conclusions to use hormones and in especial anti-aromase letrozole because of the shortage of sufficient data in current references.

    Beschreibung: Biological characteristics of Liza klunzingeri were studied in two coastal areas, Sajaphi and Bahrekan, of eastern Khuzestan during March to February 2007. Among total 1880 measured fish specimens, 947 specimens were analyzed. The mean value of Gonado-somatic Index (GSI) for the male and female fish were calculated as 0.96± 1.39 and 3.25 ± 3.26 respectively. The GSI value was highest in November and lowest in July. The mean value of condition factor (K) was 1.25± 0.14 in male and 1.21± 0.15 for female. The highest K value were observed in June and the lowest value in February. The lenght at first maturity regardless of sexuality, was found to be 14.5 cm and the time of spawning based on reproduction pattern were determined in Nov- Dec. The length-weight relationship were calculated as Y=0.024L^2.76 (n=226R2=0.72) for males, Y=0.011L^3.00 (n=444R2= 0.78) for females and Y=0.0208L^2.82 (n=670R2 =0.82) for total fishes and also it’s found significant in level lengthweight relationship in (P〈0.05). According to biological characteristics and referring to American fisheries society (AFS) indices and Fuzzy logic expert system, Lize klunzingeri is classified as low vulnerable species.

    Beschreibung: The most important habitats of mudskippers are muddy areas in tidal zone of tropical mangrove forests. Mudskippers are related to Oxudercinae subfamily of Gobiid fishes. Three most distributed species of Hormozgan mudskippers were Periophthalmus waltoni, Boleophthalmus dussumieri and Scartelaos tenuis. These fishes can be considered as euryhaline and eurythermal aquatic species, because they can tolerate a wide range of salinity and temperature. A research was done since september 2008 to september 2009 in two important mangrove regions of Hormuzgan (Tyab and Khamir) to determine some ecological characteristics of inhabited mudskipper species. Results showed that nitrate levels are significantly different between tidal lines and seasons (P〈0.05). Maximum nitrite concentrations were recorded 53.2 and 92.5 µg/l in Khamir and Tyab respectively. The annual correlation matrix showed that a positive correlation between phosphate concentration and nitrite and silicate (P〈0.05). Silicate concentration was very high, because of too low density of diatoms and radiolarians. Some species of diatoms, dinoflagellates, cyanobacteria and larvae of crustacea and echinoderms were observed with different density and diversity. Sediment composition of the studied areas were categorized in three classes (clay, sand and clay - sand). Polychaetes formed dominant group of benthic fauna in Tyab and Khamir areas. High density of capitellid worms was possibly related to some environmntal stress caused by activity of fishing and cargo vessels. It was not observed significant difference between fishes length in two areas (P〈0.05); Mean lengths of P. waltoni, B. dussumieri and S. tenuis were calculated 9.85, 14.7 and 11.5 cm respectively. Spawning period of each three species in both areas were obtained from late winter to late spring based on gonadosomatic index values. Male to female sex ratio of P. waltoni, B. dussumieri and S. tenuis were calculated 1:0.45, 1:0.41and 1:0.74 respectively. Absolute fecundity of P. waltoni, B. dussumieri and S. tenuis were estimated 3558 ± 2202, 3952 ± 1030 and 6742 ± 1939 respectively. P. waltoni feeds mainly on fiddler crab, S. tenuis uses crustaceans and gastropods and B. dussumieri has a vegetarian diet.

    Beschreibung: Aquaculture for human consuming species is being considered as the first substitution of catching aquatic species due to increase of human population and decrease of wild aquatic stocks. In this study, the hybrid sturgeon Bester (female beluga x male sterlet ) was produced for the first time in Iran. Sperm of 1.35 kg male Acipenser ruthenus was used to fertilize the eggs of 125 kg female Huso huso in Shahid Marjani Sturgeon propagation center (Agh Ghala, Golestan province). The fries of bester and control treatment of beluga were transported to International Sturgeon Research Institute (Rasht) after about one month by reaching to 490 mg and 377 mg of weight respectively. All fishes fed by artificial concentrated food (48-50% protein and 15-17% fat) after a period of feeding with Artemia and Daphnia. Sorting was carried out according to increase of fish weight for both fishes. Results showed that the imported sterlet spawners were not at the high maturation stages and especially the males had not suitable sperm quality. It showed that up to 2 months of age , these was no significant difference between bester and beluga weight but from this age up to 2 months of age the weight of beluga was greater. Meanwhile from 2 months old up to the end of the study (21 months) the weight of bester sample was significantly greater than beluga. The comparison of FCR for the whole rearing period showed no difference between bester and beluga (2.4 and 2.3 respectively). In general, the increase and decrease pattern of GR and SGR were coincided to each other, but showed monthly differences. Growth rate (GR) and specific growth rate (SGR) of bester were greater than beluga from 4th and 3rd month of rearing period respectively.

    Beschreibung: The present study was firstly conducted to study the rate of sexual maturity in Nereis diversicolor under suitable conditions of temperature and photoperiod. The second objective was to determine the potential of artificial breeding in these worms for mass culture. Nereis diversicolor worms were collected from the Anzali lagoon in 4000 sampling operations during the years 2004 to 2006 using Ekman grab with a surface area of 400 cm2. The water salinity, temperature and total organic matter (TOM) of sediments in the sampling region was recorded. The worms were maintained in 0.5 tons (1 x 1 m2) tanks containing clayey-muddy sediment to a height of 20 cm covered with 10 cm water (5 ‰) until they reached a weight of 200-300 mg. Sexual maturity in this species was attained at 4-6 ºC and spawning occurred at approximately 16 ºC. The first gametes were observed five weeks after the temperature increased from 6 to 16 ºC. Sexual maturity was studied at various salinities (0.5, 5, 12, and 15 ‰). Results indicate that these worms attained earlier sexual maturity at salinity of 15 ‰, compared to other salinities studied. No significant differences (P〉0.05) were observed between sexual maturity attained at 12 ‰ and 15 ‰. Stocking density (20, 50, 100, 150 worms) was studied in terms of sex and showed that number of females were higher than males and the ratio was 11:1 (female:male). No significant differences (P〉0.05) were observed between the various stocking densities and their replicates. The effect of light and photoperiod in synchronizing reproduction in male and female N. diversicolor was studied. It was evident that reproduction behavior in adult worms increased for a period of one week at the end of each month after they are exposed to a prolonged photoperiod (L:D=16:8) followed by a period of dim light (simulated using 1 W lamps). Feeding trials were carried out with Saccharomyces cerevisiae, formulated fish diets and humus. Results showed that this diet was effective in speeding up sexual maturity in worms and significant effect of treatment was observed (P〈0.05) in worms fed a diet of humus alone. Eggs and sperms were fertilized and worms developed from the young monotrochophore with jelly layer to the trochophore larvae.

    Beschreibung: The operations of this project commenced with the capture and tagging of four spawners in the spring of 2006 and 2007 in the Sepidrud River. Three male Acipenser persicus spawners and one male A. stellatus spawner were collected by beach seine (120 m long, 6 m high and mesh size of 10 and 15 cm) and waiting nets. Spawners were tagged with radio transmitters with a frequency between 150-151 MHz. These transmitters were used for the first time in Iran on fish. Signals were received using a radio receiver model WTI-1000 (Wildlife Track Inc.) with Yagi antennae and a Telex ProAir 1500 earphone. Tagged spawners were tracked from the land (along the river margin) and in water in motor boats. The aim of this study was to study the potential for migration and natural reproduction in sturgeons in the Sepidrud River. Water temperature during the study period varied between 12-26 ֯C in the first year and between 16-22 ֯C in the second year of the study. The A. stellatus spawner weighed 6 kg while the A. persicus spawners weighed between 11 to 25 kg. Sperm motility of A. stellatus spawner was 39%, sperm density was 0.42x109 ml and motility time was 15 sec., while in A. persicus spawners, sperm motility varied between 50-65%, sperm density was between 0.500x109 to 0.865x109 ml and motility time of sperms varied between 20-42 sec. Tracking tagged spawners revealed that A. stellatus spawners moved at an average speed of 1100 m h-1 (influenced by the strong currents in the river) while A. persicus spawners moved downstream at an average speed of 90 m h-1. Results of the present study indicate the presence of potential barriers such as water temperature, river water flow, physiological conditions of spawners in terms of sexual maturity, and the presence of fishers and fishing gear, for the migration of sturgeon spawners in the Sepidrud River. However the spawners were able to escape the various fishing gear set up in the Sepidrud River and return to the sea, indicating the possibility of natural reproduction in this river.

    Beschreibung: The Kutum, Rutilus frisii kutum, is one of the most important bony fishes in Iranian coastal of Caspian Sea. Its harvest range is between 9000-10000 tons in a year, nearly 60% of the income of Bony fish fishery produced by kutum fishery. The stock of this species reduced drastically in 1982 and the catch slumped to the less than 250 tons in a year. Kutum spawning grounds deterioration, illegal catch, lack of restocking program were the main cause of the decline. This Spices in nature comprised by two distinct form, autumn and spring form. It is worth to be mentioned, by the effect of Caspian Sea Bony fishes Research Center s experts in 1983, artificial spawning and releasing the fries to the sea were commenced and the catch steadily improved. But all activities concerning restocking of kutum concentrated in spring form, as at present about 260 million its fries are released into sea for restocking by Iranian Fisheries Organization, but for above reasons and lack of restocking program, the populations of autumn form gravely shrinked and neared to be extinct. Therefore, to enhance the biodiversity and boost fishers livelihood of kutum in Caspian Sea this project implemented by cooperation of Iranian Fisheries Organization (IFRO) and Caspian Environment Program (CEP) in Aquaculture Institute (Inland Waters). In this project, brooders caught from Anzali lagoon and maintained in two different condition, include of floating cages in Anzali lagoon and earthen ponds in Sefidrud Fisheries Research Station. The results showed that there weren t significant differences between two maintenance statuses in maturation period and other reproductive characteristics of brooders. The ratio of male to female was 1 to 1.4. Minimum and maximum weight measured 1450 to 3100 g (with average of 1850 g) in female and 670 to 1900 g (with average of 1165 g) in male, respectively. The first natural spawning of brooders occurred in the end of January in temperature of 8 till 10 °C in concrete ponds. Also, some of maintained brooders in earthen ponds spawned in February. The average number of absolute, function and relative fecundity determined 88565 16809, 73805 14008 and 48670 12056, respectively. For artificial spawning, male and female brooders injected by pituitary gland with dose of 2-3 and 4-5 mg/kg body weight, respectively. Approximately, 10 and 8 present of female were over-ripe and immature in March (artificial spawning time), respectively. More than 59 % of injected female brooders induced to spawning in first stage after 10-12 hours and 13 % of them in twice stage and 7-8 hours after first stage. And also, 27.6% of females didn’t positive response to injection. Dry method used for eggs fecundity and incubation period lasted 7- 10 days in 14-16 °C. In totally, eggs fertilization were more than 95% and the average of eggs fertilization percent in throughout of period measured more than 92.7 6 %. Eyed eggs appearance occurred 3 days after fecundity and its mean was 92.7 15.1%. Larvae after yolk sac absorption feed with dry milk for 4-5 days and then introduced into fertilized earthen ponds (500 m2 and equipped to aerators) in intensive condition and fed with micro pellet food for 3-4 month. In finally, more than 1.8 millions fries of 1-2 g and some more than 5 g produced and released into Anzali lagoon to its restocking for first time. It is expected that continuing of restocking process of autumn form kutum by Iranian Fisheries Organization eventuate to population increasing of this form in Caspian Sea in future.

The results showed that, Gonadosomatic index (GSI) in treatments 3: control and 6, was significantly more than others treatments (p〈0.05). Hepatosomatic indexes, in often treatments was almost equal, and in some cases were significantly different (p〈0.05). In treatments 3 and control, absolute fequndity, was significantly more than others treatment (p〈0.05). The survival percent, in treatment 8 was significantly less than others treatments (p〈0.05). The survival percent in others treatments was not significantly difference (p〉0.05). From the aspect of mean weight of broodstock, wasn’t significant difference in treatments (p〉0.05). From the aspect of mean length of carapac, wasn’t significant difference in treatments (p〉0.05). From the aspect of mean body length, wasn’t significant difference in often treatments (p〉0.05), and in treatments 5 and 6 was significantly less than others (p〈0.05). In the determination of relasheship between kind of treatments and abundance of maturated broodsock, wasn’t significantly difference (p〉0.05). In the determination of, correlation between weight (g) and total length(cm), (r=0.71), weight and carapace length (cm) (r=0.70), the correlation was strong. Between GSI, HIS, carapace length and total length the correlation was intermediate (r=0.54). The correlation between absolutely fecundity and total length (r=0.20), absolutely fecundity and carapace length (r=0.28), absolutely fecundity and weight (r=0.35) was weak. The results showed that, the use of combination of pelleted diet and natural wet diets can increase female maturation indexes. Totally we can noted that, GSI, HIS and absolute fecundity of broodstock, that fed with pelleted diet contain 40 percent crude protein and 10 percent crude fat (50 %)+sand worm (16 %)+cattle fish (18 %) and veal livier (16 %) (treatment 3) was better than the other treatments. Positive effects of this treatnent on sexual indexes, was due to provide part of nutritional requirement of shrimp broodstock from pelleted diet.

    Beschreibung: Massive open online courses (MOOCs) are often characterized as remedies to educational disparities related to social class. Using data from 68 MOOCs offered by Harvard and MIT between 2012 and 2014, we found that course participants from the United States tended to live in more-affluent and better-educated neighborhoods than the average U.S. resident. Among those who did register for courses, students with greater socioeconomic resources were more likely to earn a certificate. Furthermore, these differences in MOOC access and completion were larger for adolescents and young adults, the traditional ages where people find on-ramps into science, technology, engineering, and mathematics (STEM) coursework and careers. Our findings raise concerns that MOOCs and similar approaches to online learning can exacerbate rather than reduce disparities in educational outcomes related to socioeconomic status.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hansen, John D -- Reich, Justin -- New York, N.Y. -- Science. 2015 Dec 4;350(6265):1245-8. doi: 10.1126/science.aab3782.

    Beschreibung: Mitochondrial morphology is shaped by fusion and division of their membranes. Here, we found that adult myocardial function depends on balanced mitochondrial fusion and fission, maintained by processing of the dynamin-like guanosine triphosphatase OPA1 by the mitochondrial peptidases YME1L and OMA1. Cardiac-specific ablation of Yme1l in mice activated OMA1 and accelerated OPA1 proteolysis, which triggered mitochondrial fragmentation and altered cardiac metabolism. This caused dilated cardiomyopathy and heart failure. Cardiac function and mitochondrial morphology were rescued by Oma1 deletion, which prevented OPA1 cleavage. Feeding mice a high-fat diet or ablating Yme1l in skeletal muscle restored cardiac metabolism and preserved heart function without suppressing mitochondrial fragmentation. Thus, unprocessed OPA1 is sufficient to maintain heart function, OMA1 is a critical regulator of cardiomyocyte survival, and mitochondrial morphology and cardiac metabolism are intimately linked.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wai, Timothy -- Garcia-Prieto, Jaime -- Baker, Michael J -- Merkwirth, Carsten -- Benit, Paule -- Rustin, Pierre -- Ruperez, Francisco Javier -- Barbas, Coral -- Ibanez, Borja -- Langer, Thomas -- New York, N.Y. -- Science. 2015 Dec 4;350(6265):aad0116. doi: 10.1126/science.aad0116.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genetics, University of Cologne, 50674 Cologne, Germany.

    Beschreibung: Mono-ubiquitination of Fancd2 is essential for repairing DNA interstrand cross-links (ICLs), but the underlying mechanisms are unclear. The Fan1 nuclease, also required for ICL repair, is recruited to ICLs by ubiquitinated (Ub) Fancd2. This could in principle explain how Ub-Fancd2 promotes ICL repair, but we show that recruitment of Fan1 by Ub-Fancd2 is dispensable for ICL repair. Instead, Fan1 recruitment--and activity--restrains DNA replication fork progression and prevents chromosome abnormalities from occurring when DNA replication forks stall, even in the absence of ICLs. Accordingly, Fan1 nuclease-defective knockin mice are cancer-prone. Moreover, we show that a Fan1 variant in high-risk pancreatic cancers abolishes recruitment by Ub-Fancd2 and causes genetic instability without affecting ICL repair. Therefore, Fan1 recruitment enables processing of stalled forks that is essential for genome stability and health.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4770513/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4770513/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lachaud, Christophe -- Moreno, Alberto -- Marchesi, Francesco -- Toth, Rachel -- Blow, J Julian -- Rouse, John -- WT096598MA/Wellcome Trust/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2016 Feb 19;351(6275):846-9. doi: 10.1126/science.aad5634.

    Beschreibung: Maintaining energy homeostasis is crucial for the survival and health of organisms. The brain regulates feeding by responding to dietary factors and metabolic signals from peripheral organs. It is unclear how the brain interprets these signals. O-GlcNAc transferase (OGT) catalyzes the posttranslational modification of proteins by O-GlcNAc and is regulated by nutrient access. Here, we show that acute deletion of OGT from alphaCaMKII-positive neurons in adult mice caused obesity from overeating. The hyperphagia derived from the paraventricular nucleus (PVN) of the hypothalamus, where loss of OGT was associated with impaired satiety. These results identify O-GlcNAcylation in alphaCaMKII neurons of the PVN as an important molecular mechanism that regulates feeding behavior.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4817221/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4817221/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lagerlof, Olof -- Slocomb, Julia E -- Hong, Ingie -- Aponte, Yeka -- Blackshaw, Seth -- Hart, Gerald W -- Huganir, Richard L -- N01-HV-00240/HV/NHLBI NIH HHS/ -- P01 HL107153/HL/NHLBI NIH HHS/ -- P01HL107153/HL/NHLBI NIH HHS/ -- R01 DK061671/DK/NIDDK NIH HHS/ -- R01 NS036715/NS/NINDS NIH HHS/ -- R01DK6167/DK/NIDDK NIH HHS/ -- R01NS036715/NS/NINDS NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2016 Mar 18;351(6279):1293-6. doi: 10.1126/science.aad5494.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Solomon H.

They discuss alternate analyses of average firing rates in other tasks, the relationship between neural activity and behavior, and possible extensions of the standard models we examined. Although interesting to contemplate, these points are not germane to the findings of our Report: that stepping dynamics provided a better statistical description of lateral intraparietal area spike trains than diffusion-to-bound dynamics for a majority of neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Latimer, Kenneth W -- Yates, Jacob L -- Meister, Miriam L R -- Huk, Alexander C -- Pillow, Jonathan W -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1406. doi: 10.1126/science.aad3596.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Perceptual Systems, The University of Texas at Austin, Austin, TX 78712, USA.

    Beschreibung: Latimeret al (Reports, 10 July 2015, p. 184) claim that during perceptual decision formation, parietal neurons undergo one-time, discrete steps in firing rate instead of gradual changes that represent the accumulation of evidence. However, that conclusion rests on unsubstantiated assumptions about the time window of evidence accumulation, and their stepping model cannot explain existing data as effectively as evidence-accumulation models.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shadlen, Michael N -- Kiani, Roozbeh -- Newsome, William T -- Gold, Joshua I -- Wolpert, Daniel M -- Zylberberg, Ariel -- Ditterich, Jochen -- de Lafuente, Victor -- Yang, Tianming -- Roitman, Jamie -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1406. doi: 10.1126/science.aad3242.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute (HHMI) and Department of Neuroscience, Columbia University, New York, NY, USA. shadlen@columbia.edu. ; Center for Neural Science, New York University, New York, NY, USA. ; HHMI and Stanford University, Stanford, CA, USA. ; Department of Neuroscience, University of Pennsylvania, Philadelphia, PA, USA. ; Department of Engineering, University of Cambridge, Cambridge, UK. ; HHMI and Department of Neuroscience, Columbia University, New York, NY, USA. ; Center for Neuroscience and Department of Neurobiology, Physiology, and Behavior, University of California, Davis, CA, USA. ; Institute for Neuroscience, National Autonomous University of Mexico, Queretaro, Mexico. ; Institute of Neuroscience, Chinese Academy of Sciences, Shanghai, China. ; Department of Psychology, University of Illinois at Chicago, Chicago, IL, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/27013723" target="_blank"〉PubMed〈/a〉

    Beschreibung: Several recent studies link parental environments to phenotypes in subsequent generations. In this work, we investigate the mechanism by which paternal diet affects offspring metabolism. Protein restriction in mice affects small RNA (sRNA) levels in mature sperm, with decreased let-7 levels and increased amounts of 5' fragments of glycine transfer RNAs (tRNAs). In testicular sperm, tRNA fragments are scarce but increase in abundance as sperm mature in the epididymis. Epididymosomes (vesicles that fuse with sperm during epididymal transit) carry RNA payloads matching those of mature sperm and can deliver RNAs to immature sperm in vitro. Functionally, tRNA-glycine-GCC fragments repress genes associated with the endogenous retroelement MERVL, in both embryonic stem cells and embryos. Our results shed light on sRNA biogenesis and its dietary regulation during posttesticular sperm maturation, and they also link tRNA fragments to regulation of endogenous retroelements active in the preimplantation embryo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sharma, Upasna -- Conine, Colin C -- Shea, Jeremy M -- Boskovic, Ana -- Derr, Alan G -- Bing, Xin Y -- Belleannee, Clemence -- Kucukural, Alper -- Serra, Ryan W -- Sun, Fengyun -- Song, Lina -- Carone, Benjamin R -- Ricci, Emiliano P -- Li, Xin Z -- Fauquier, Lucas -- Moore, Melissa J -- Sullivan, Robert -- Mello, Craig C -- Garber, Manuel -- Rando, Oliver J -- DP1ES025458/DP/NCCDPHP CDC HHS/ -- R01HD080224/HD/NICHD NIH HHS/ -- UL1 TR000161/TR/NCATS NIH HHS/ -- UL1 TR001453/TR/NCATS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Jan 22;351(6271):391-6. doi: 10.1126/science.aad6780.

    Beschreibung: Noncoding variants play a central role in the genetics of complex traits, but we still lack a full understanding of the molecular pathways through which they act. We quantified the contribution of cis-acting genetic effects at all major stages of gene regulation from chromatin to proteins, in Yoruba lymphoblastoid cell lines (LCLs). About ~65% of expression quantitative trait loci (eQTLs) have primary effects on chromatin, whereas the remaining eQTLs are enriched in transcribed regions. Using a novel method, we also detected 2893 splicing QTLs, most of which have little or no effect on gene-level expression. These splicing QTLs are major contributors to complex traits, roughly on a par with variants that affect gene expression levels. Our study provides a comprehensive view of the mechanisms linking genetic variation to variation in human gene regulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Yang I -- van de Geijn, Bryce -- Raj, Anil -- Knowles, David A -- Petti, Allegra A -- Golan, David -- Gilad, Yoav -- Pritchard, Jonathan K -- R01MH084703/MH/NIMH NIH HHS/ -- R01MH101825/MH/NIMH NIH HHS/ -- U01HG007036/HG/NHGRI NIH HHS/ -- U54CA149145/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Apr 29;352(6285):600-4. doi: 10.1126/science.aad9417.

    Beschreibung: Ebola virus disease in humans is highly lethal, with case fatality rates ranging from 25 to 90%. There is no licensed treatment or vaccine against the virus, underscoring the need for efficacious countermeasures. We ascertained that a human survivor of the 1995 Kikwit Ebola virus disease outbreak maintained circulating antibodies against the Ebola virus surface glycoprotein for more than a decade after infection. From this survivor we isolated monoclonal antibodies (mAbs) that neutralize recent and previous outbreak variants of Ebola virus and mediate antibody-dependent cell-mediated cytotoxicity in vitro. Strikingly, monotherapy with mAb114 protected macaques when given as late as 5 days after challenge. Treatment with a single human mAb suggests that a simplified therapeutic strategy for human Ebola infection may be possible.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Corti, Davide -- Misasi, John -- Mulangu, Sabue -- Stanley, Daphne A -- Kanekiyo, Masaru -- Wollen, Suzanne -- Ploquin, Aurelie -- Doria-Rose, Nicole A -- Staupe, Ryan P -- Bailey, Michael -- Shi, Wei -- Choe, Misook -- Marcus, Hadar -- Thompson, Emily A -- Cagigi, Alberto -- Silacci, Chiara -- Fernandez-Rodriguez, Blanca -- Perez, Laurent -- Sallusto, Federica -- Vanzetta, Fabrizia -- Agatic, Gloria -- Cameroni, Elisabetta -- Kisalu, Neville -- Gordon, Ingelise -- Ledgerwood, Julie E -- Mascola, John R -- Graham, Barney S -- Muyembe-Tamfun, Jean-Jacques -- Trefry, John C -- Lanzavecchia, Antonio -- Sullivan, Nancy J -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2016 Mar 18;351(6279):1339-42. doi: 10.1126/science.aad5224.

    Beschreibung: CRISPR/Cas9-mediated genome editing holds clinical potential for treating genetic diseases, such as Duchenne muscular dystrophy (DMD), which is caused by mutations in the dystrophin gene. To correct DMD by skipping mutant dystrophin exons in postnatal muscle tissue in vivo, we used adeno-associated virus-9 (AAV9) to deliver gene-editing components to postnatal mdx mice, a model of DMD. Different modes of AAV9 delivery were systematically tested, including intraperitoneal at postnatal day 1 (P1), intramuscular at P12, and retro-orbital at P18. Each of these methods restored dystrophin protein expression in cardiac and skeletal muscle to varying degrees, and expression increased from 3 to 12 weeks after injection. Postnatal gene editing also enhanced skeletal muscle function, as measured by grip strength tests 4 weeks after injection. This method provides a potential means of correcting mutations responsible for DMD and other monogenic disorders after birth.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4760628/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4760628/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Long, Chengzu -- Amoasii, Leonela -- Mireault, Alex A -- McAnally, John R -- Li, Hui -- Sanchez-Ortiz, Efrain -- Bhattacharyya, Samadrita -- Shelton, John M -- Bassel-Duby, Rhonda -- Olson, Eric N -- DK-099653/DK/NIDDK NIH HHS/ -- HL-077439/HL/NHLBI NIH HHS/ -- HL-093039/HL/NHLBI NIH HHS/ -- HL-111665/HL/NHLBI NIH HHS/ -- R01 DK099653/DK/NIDDK NIH HHS/ -- R01 HL077439/HL/NHLBI NIH HHS/ -- R01 HL093039/HL/NHLBI NIH HHS/ -- R01 HL111665/HL/NHLBI NIH HHS/ -- U01 HL100401/HL/NHLBI NIH HHS/ -- U01-HL-100401/HL/NHLBI NIH HHS/ -- U54 HD 087351/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2016 Jan 22;351(6271):400-3. doi: 10.1126/science.aad5725.

    Beschreibung: Global climate change is a major threat to biodiversity. Large-scale analyses have generally focused on the impacts of climate change on the geographic ranges of species and on phenology, the timing of ecological phenomena. We used long-term monitoring of the abundance of breeding birds across Europe and the United States to produce, for both regions, composite population indices for two groups of species: those for which climate suitability has been either improving or declining since 1980. The ratio of these composite indices, the climate impact indicator (CII), reflects the divergent fates of species favored or disadvantaged by climate change. The trend in CII is positive and similar in the two regions. On both continents, interspecific and spatial variation in population abundance trends are well predicted by climate suitability trends.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stephens, Philip A -- Mason, Lucy R -- Green, Rhys E -- Gregory, Richard D -- Sauer, John R -- Alison, Jamie -- Aunins, Ainars -- Brotons, Lluis -- Butchart, Stuart H M -- Campedelli, Tommaso -- Chodkiewicz, Tomasz -- Chylarecki, Przemyslaw -- Crowe, Olivia -- Elts, Jaanus -- Escandell, Virginia -- Foppen, Ruud P B -- Heldbjerg, Henning -- Herrando, Sergi -- Husby, Magne -- Jiguet, Frederic -- Lehikoinen, Aleksi -- Lindstrom, Ake -- Noble, David G -- Paquet, Jean-Yves -- Reif, Jiri -- Sattler, Thomas -- Szep, Tibor -- Teufelbauer, Norbert -- Trautmann, Sven -- van Strien, Arco J -- van Turnhout, Chris A M -- Vorisek, Petr -- Willis, Stephen G -- New York, N.Y. -- Science. 2016 Apr 1;352(6281):84-7. doi: 10.1126/science.aac4858.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Conservation Ecology Group, School of Biological and Biomedical Sciences, Durham University, South Road, Durham DH1 3LE, UK. ; Royal Society for the Protection of Birds, Centre for Conservation Science, The Lodge, Sandy, Bedfordshire SG19 2DL, UK. ; Royal Society for the Protection of Birds, Centre for Conservation Science, The Lodge, Sandy, Bedfordshire SG19 2DL, UK.

    Beschreibung: Sanchez et al.'s textbook k-anonymization example does not prove, or even suggest, that location and other big-data data sets can be anonymized and of general use. The synthetic data set that they "successfully anonymize" bears no resemblance to modern high-dimensional data sets on which their methods fail. Moving forward, deidentification should not be considered a useful basis for policy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉de Montjoye, Yves-Alexandre -- Pentland, Alex Sandy -- New York, N.Y. -- Science. 2016 Mar 18;351(6279):1274. doi: 10.1126/science.aaf1578.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Massachusetts Institute of Technology, Cambridge, MA 02139, USA.

    Beschreibung: Hydroxymethylcytosine, well described in DNA, occurs also in RNA. Here, we show that hydroxymethylcytosine preferentially marks polyadenylated RNAs and is deposited by Tet in Drosophila. We map the transcriptome-wide hydroxymethylation landscape, revealing hydroxymethylcytosine in the transcripts of many genes, notably in coding sequences, and identify consensus sites for hydroxymethylation. We found that RNA hydroxymethylation can favor mRNA translation. Tet and hydroxymethylated RNA are found to be most abundant in the Drosophila brain, and Tet-deficient fruitflies suffer impaired brain development, accompanied by decreased RNA hydroxymethylation. This study highlights the distribution, localization, and function of cytosine hydroxymethylation and identifies central roles for this modification in Drosophila.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Delatte, Benjamin -- Wang, Fei -- Ngoc, Long Vo -- Collignon, Evelyne -- Bonvin, Elise -- Deplus, Rachel -- Calonne, Emilie -- Hassabi, Bouchra -- Putmans, Pascale -- Awe, Stephan -- Wetzel, Collin -- Kreher, Judith -- Soin, Romuald -- Creppe, Catherine -- Limbach, Patrick A -- Gueydan, Cyril -- Kruys, Veronique -- Brehm, Alexander -- Minakhina, Svetlana -- Defrance, Matthieu -- Steward, Ruth -- Fuks, Francois -- R01 GM089992/GM/NIGMS NIH HHS/ -- T32 CA117846/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2016 Jan 15;351(6270):282-5. doi: 10.1126/science.aac5253.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cancer Epigenetics, Faculty of Medicine, ULB Cancer Research Center (U-CRC), Universite Libre de Bruxelles (ULB), Brussels, Belgium. ; Waksman Institute, Department of Molecular Biology and Biochemistry, Cancer Institute of New Jersey, Rutgers University, Piscataway, NJ, USA. ; Laboratory of Molecular Biology of the Gene, Faculty of Sciences, Universite Libre de Bruxelles, Gosselies, Belgium. ; Institut fur Molekularbiologie und Tumorforschung, Philipps-Universitat Marburg, Marburg, Germany. ; Department of Chemistry, University of Cincinnati, Cincinnati, OH, USA. ; Laboratory of Cancer Epigenetics, Faculty of Medicine, ULB Cancer Research Center (U-CRC), Universite Libre de Bruxelles (ULB), Brussels, Belgium. ffuks@ulb.ac.be.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26816380" target="_blank"〉PubMed〈/a〉

    Beschreibung: Genes encoding human beta-type globin undergo a developmental switch from embryonic to fetal to adult-type expression. Mutations in the adult form cause inherited hemoglobinopathies or globin disorders, including sickle cell disease and thalassemia. Some experimental results have suggested that these diseases could be treated by induction of fetal-type hemoglobin (HbF). However, the mechanisms that repress HbF in adults remain unclear. We found that the LRF/ZBTB7A transcription factor occupies fetal gamma-globin genes and maintains the nucleosome density necessary for gamma-globin gene silencing in adults, and that LRF confers its repressive activity through a NuRD repressor complex independent of the fetal globin repressor BCL11A. Our study may provide additional opportunities for therapeutic targeting in the treatment of hemoglobinopathies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4778394/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4778394/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Masuda, Takeshi -- Wang, Xin -- Maeda, Manami -- Canver, Matthew C -- Sher, Falak -- Funnell, Alister P W -- Fisher, Chris -- Suciu, Maria -- Martyn, Gabriella E -- Norton, Laura J -- Zhu, Catherine -- Kurita, Ryo -- Nakamura, Yukio -- Xu, Jian -- Higgs, Douglas R -- Crossley, Merlin -- Bauer, Daniel E -- Orkin, Stuart H -- Kharchenko, Peter V -- Maeda, Takahiro -- R01 AI084905/AI/NIAID NIH HHS/ -- R01 HL032259/HL/NHLBI NIH HHS/ -- R56 DK105001/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2016 Jan 15;351(6270):285-9. doi: 10.1126/science.aad3312.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology, Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115, USA. ; Department of Biomedical Informatics, Harvard Medical School, Boston, MA 02115, USA. ; Division of Hematology/Oncology, Boston Children's Hospital, Department of Pediatric Oncology, Dana-Farber Cancer Institute, Harvard Stem Cell Institute, Department of Pediatrics, Harvard Medical School, Boston, MA 02115, USA. ; School of Biotechnology and Biomolecular Sciences, University of New South Wales, Sydney, NSW 2052, Australia. ; Medical Research Council, Molecular Haematology Unit, Weatherall Institute of Molecular Medicine, Oxford University, Oxford, UK. ; Cell Engineering Division, RIKEN BioResource Center, Tsukuba, Ibaraki, Japan. ; Cell Engineering Division, RIKEN BioResource Center, Tsukuba, Ibaraki, Japan.

    Beschreibung: Wakefulness is driven by the widespread release of neuromodulators by the ascending arousal system. Yet, it is unclear how these substances orchestrate state-dependent, global changes in neuronal activity. Here, we show that neuromodulators induce increases in the extracellular K(+) concentration ([K(+)]e) in cortical slices electrically silenced by tetrodotoxin. In vivo, arousal was linked to AMPA receptor-independent elevations of [K(+)]e concomitant with decreases in [Ca(2+)]e, [Mg(2+)]e, [H(+)]e, and the extracellular volume. Opposite, natural sleep and anesthesia reduced [K(+)]e while increasing [Ca(2+)]e, [Mg(2+)]e, and [H(+)]e as well as the extracellular volume. Local cortical activity of sleeping mice could be readily converted to the stereotypical electroencephalography pattern of wakefulness by simply imposing a change in the extracellular ion composition. Thus, extracellular ions control the state-dependent patterns of neural activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ding, Fengfei -- O'Donnell, John -- Xu, Qiwu -- Kang, Ning -- Goldman, Nanna -- Nedergaard, Maiken -- NS078167/NS/NINDS NIH HHS/ -- NS078304/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 29;352(6285):550-5. doi: 10.1126/science.aad4821.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Translational Neuromedicine, University of Rochester Medical Center, Rochester, NY 14642, USA.

    Beschreibung: Activation of various cell surface receptors triggers the reorganization of downstream signaling molecules into micrometer- or submicrometer-sized clusters. However, the functional consequences of such clustering have been unclear. We biochemically reconstituted a 12-component signaling pathway on model membranes, beginning with T cell receptor (TCR) activation and ending with actin assembly. When TCR phosphorylation was triggered, downstream signaling proteins spontaneously separated into liquid-like clusters that promoted signaling outputs both in vitro and in human Jurkat T cells. Reconstituted clusters were enriched in kinases but excluded phosphatases and enhanced actin filament assembly by recruiting and organizing actin regulators. These results demonstrate that protein phase separation can create a distinct physical and biochemical compartment that facilitates signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Su, Xiaolei -- Ditlev, Jonathon A -- Hui, Enfu -- Xing, Wenmin -- Banjade, Sudeep -- Okrut, Julia -- King, David S -- Taunton, Jack -- Rosen, Michael K -- Vale, Ronald D -- 5-F32-DK101188/DK/NIDDK NIH HHS/ -- F32 DK101188/DK/NIDDK NIH HHS/ -- R01 GM056322/GM/NIGMS NIH HHS/ -- R01-GM56322/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Apr 29;352(6285):595-9. doi: 10.1126/science.aad9964.

    Beschreibung: During corticogenesis, excitatory neurons are born from progenitors located in the ventricular zone (VZ), from where they migrate to assemble into circuits. How neuronal identity is dynamically specified upon progenitor division is unknown. Here, we study this process using a high-temporal-resolution technology allowing fluorescent tagging of isochronic cohorts of newborn VZ cells. By combining this in vivo approach with single-cell transcriptomics in mice, we identify and functionally characterize neuron-specific primordial transcriptional programs as they dynamically unfold. Our results reveal early transcriptional waves that instruct the sequence and pace of neuronal differentiation events, guiding newborn neurons toward their final fate, and contribute to a road map for the reverse engineering of specific classes of cortical neurons from undifferentiated cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Telley, Ludovic -- Govindan, Subashika -- Prados, Julien -- Stevant, Isabelle -- Nef, Serge -- Dermitzakis, Emmanouil -- Dayer, Alexandre -- Jabaudon, Denis -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1443-6. doi: 10.1126/science.aad8361.

    Beschreibung: As tumors grow, they acquire mutations, some of which create neoantigens that influence the response of patients to immune checkpoint inhibitors. We explored the impact of neoantigen intratumor heterogeneity (ITH) on antitumor immunity. Through integrated analysis of ITH and neoantigen burden, we demonstrate a relationship between clonal neoantigen burden and overall survival in primary lung adenocarcinomas. CD8(+)tumor-infiltrating lymphocytes reactive to clonal neoantigens were identified in early-stage non-small cell lung cancer and expressed high levels of PD-1. Sensitivity to PD-1 and CTLA-4 blockade in patients with advanced NSCLC and melanoma was enhanced in tumors enriched for clonal neoantigens. T cells recognizing clonal neoantigens were detectable in patients with durable clinical benefit. Cytotoxic chemotherapy-induced subclonal neoantigens, contributing to an increased mutational load, were enriched in certain poor responders. These data suggest that neoantigen heterogeneity may influence immune surveillance and support therapeutic developments targeting clonal neoantigens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGranahan, Nicholas -- Furness, Andrew J S -- Rosenthal, Rachel -- Ramskov, Sofie -- Lyngaa, Rikke -- Saini, Sunil Kumar -- Jamal-Hanjani, Mariam -- Wilson, Gareth A -- Birkbak, Nicolai J -- Hiley, Crispin T -- Watkins, Thomas B K -- Shafi, Seema -- Murugaesu, Nirupa -- Mitter, Richard -- Akarca, Ayse U -- Linares, Joseph -- Marafioti, Teresa -- Henry, Jake Y -- Van Allen, Eliezer M -- Miao, Diana -- Schilling, Bastian -- Schadendorf, Dirk -- Garraway, Levi A -- Makarov, Vladimir -- Rizvi, Naiyer A -- Snyder, Alexandra -- Hellmann, Matthew D -- Merghoub, Taha -- Wolchok, Jedd D -- Shukla, Sachet A -- Wu, Catherine J -- Peggs, Karl S -- Chan, Timothy A -- Hadrup, Sine R -- Quezada, Sergio A -- Swanton, Charles -- 12100/Cancer Research UK/United Kingdom -- 1R01CA155010-02/CA/NCI NIH HHS/ -- 1R01CA182461-01/CA/NCI NIH HHS/ -- 1R01CA184922-01/CA/NCI NIH HHS/ -- Cancer Research UK/United Kingdom -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1463-9. doi: 10.1126/science.aaf1490.

    Beschreibung: Astrocytes are specialized and heterogeneous cells that contribute to central nervous system function and homeostasis. However, the mechanisms that create and maintain differences among astrocytes and allow them to fulfill particular physiological roles remain poorly defined. We reveal that neurons actively determine the features of astrocytes in the healthy adult brain and define a role for neuron-derived sonic hedgehog (Shh) in regulating the molecular and functional profile of astrocytes. Thus, the molecular and physiological program of astrocytes is not hardwired during development but, rather, depends on cues from neurons that drive and sustain their specialized properties.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Farmer, W Todd -- Abrahamsson, Therese -- Chierzi, Sabrina -- Lui, Christopher -- Zaelzer, Cristian -- Jones, Emma V -- Bally, Blandine Ponroy -- Chen, Gary G -- Theroux, Jean-Francois -- Peng, Jimmy -- Bourque, Charles W -- Charron, Frederic -- Ernst, Carl -- Sjostrom, P Jesper -- Murai, Keith K -- FDN 143337/Canadian Institutes of Health Research/Canada -- MOP 111152/Canadian Institutes of Health Research/Canada -- MOP 123390/Canadian Institutes of Health Research/Canada -- MOP 126137/Canadian Institutes of Health Research/Canada -- NIA 288936/Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2016 Feb 19;351(6275):849-54. doi: 10.1126/science.aab3103.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Research in Neuroscience, Department of Neurology and Neurosurgery, Brain Repair and Integrative Neuroscience Program, The Research Institute of the McGill University Health Centre, Montreal General Hospital, Montreal, Quebec, Canada. ; Department of Psychiatry, McGill University, Montreal, Quebec, Canada.

    Beschreibung: Motivation for reward drives adaptive behaviors, whereas impairment of reward perception and experience (anhedonia) can contribute to psychiatric diseases, including depression and schizophrenia. We sought to test the hypothesis that the medial prefrontal cortex (mPFC) controls interactions among specific subcortical regions that govern hedonic responses. By using optogenetic functional magnetic resonance imaging to locally manipulate but globally visualize neural activity in rats, we found that dopamine neuron stimulation drives striatal activity, whereas locally increased mPFC excitability reduces this striatal response and inhibits the behavioral drive for dopaminergic stimulation. This chronic mPFC overactivity also stably suppresses natural reward-motivated behaviors and induces specific new brainwide functional interactions, which predict the degree of anhedonia in individuals. These findings describe a mechanism by which mPFC modulates expression of reward-seeking behavior, by regulating the dynamical interactions between specific distant subcortical regions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4772156/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4772156/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ferenczi, Emily A -- Zalocusky, Kelly A -- Liston, Conor -- Grosenick, Logan -- Warden, Melissa R -- Amatya, Debha -- Katovich, Kiefer -- Mehta, Hershel -- Patenaude, Brian -- Ramakrishnan, Charu -- Kalanithi, Paul -- Etkin, Amit -- Knutson, Brian -- Glover, Gary H -- Deisseroth, Karl -- 1F31MH105151_01/MH/NIMH NIH HHS/ -- P41 EB015891/EB/NIBIB NIH HHS/ -- R00 MH097822/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Jan 1;351(6268):aac9698. doi: 10.1126/science.aac9698.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bioengineering, Stanford University, Stanford, CA 94305, USA.

    Beschreibung: Vocal imitation involves incorporating instructive auditory information into relevant motor circuits through processes that are poorly understood. In zebra finches, we found that exposure to a tutor's song drives spiking activity within premotor neurons in the juvenile, whereas inhibition suppresses such responses upon learning in adulthood. We measured inhibitory currents evoked by the tutor song throughout development while simultaneously quantifying each bird's learning trajectory. Surprisingly, we found that the maturation of synaptic inhibition onto premotor neurons is correlated with learning but not age. We used synthetic tutoring to demonstrate that inhibition is selective for specific song elements that have already been learned and not those still in refinement. Our results suggest that structured inhibition plays a crucial role during song acquisition, enabling a piece-by-piece mastery of complex tasks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vallentin, Daniela -- Kosche, Georg -- Lipkind, Dina -- Long, Michael A -- R01NS075044/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2016 Jan 15;351(6270):267-71. doi: 10.1126/science.aad3023.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉NYU Neuroscience Institute and Department of Otolaryngology, New York University Langone Medical Center, New York, NY 10016, USA.

    Beschreibung: Berkowitz et al. (Reports, 9 October 2015, p. 196) described a randomized field experiment testing whether a math app designed to increase parent-child interaction could also bring academic benefits. A reanalysis of the data suggests that this well-designed trial failed to find strong evidence for the efficacy of the intervention. In particular, there was no significant effect of the intervention on math performance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frank, Michael C -- New York, N.Y. -- Science. 2016 Mar 11;351(6278):1161. doi: 10.1126/science.aad8008.
