    UV to far-IR reflectance spectra of carbonaceous chondrites - I. Implications for remote characterization of dark primitive asteroids targeted by sample-return missions (2013)
    Oxford University Press
    Details
    Publication Date: 2013-12-06
    Description: We analyse here a wide sample of carbonaceous chondrites from historic falls (e.g. Allende, Cold Bokkeveld, Kainsaz, Leoville, Murchison, Murray, Orgueil and Tagish Lake) and from NASA Antarctic collection. With the analysis of these meteorites we want to get new clues on the role of aqueous alteration in promoting the reflectance spectra diversity evidenced in the most primitive chondrite groups. The selected meteorite specimens are a sample large enough to exemplify how laboratory reflectance spectra of rare groups of carbonaceous chondrites exhibit distinctive features that can be used to remotely characterize the spectra of primitive asteroids. Our spectra cover the full electromagnetic spectrum from 0.2 to 25 μm by using two spectrometers. First one is an ultraviolet (UV)–near-infrared (NIR) spectrometer that covers the 0.2–2 μm window, while the second one is an attenuated total reflectance infrared spectrometer covering the 2–25 μm window. In particular, laboratory analyses in the UV–NIR window allow obtaining absolute reflectance by using standardized measurement procedures. We obtained reflectance spectra of specimens belonging to the CI, CM, CV, CR, CO, CK, CH, R and CB groups of carbonaceous chondrites plus some ungrouped ones, and it allows identifying characteristic features and bands for each class, plus getting clues on the influence of parent body aqueous alteration. These laboratory spectra can be compared with the remote spectra of asteroids, but the effects of terrestrial alteration forming (oxy)hydroxides need to be considered.

    Autophagy-dependent anticancer immune responses induced by chemotherapeutic agents in mice (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-12-17
    Description: Antineoplastic chemotherapies are particularly efficient when they elicit immunogenic cell death, thus provoking an anticancer immune response. Here we demonstrate that autophagy, which is often disabled in cancer, is dispensable for chemotherapy-induced cell death but required for its immunogenicity. In response to chemotherapy, autophagy-competent, but not autophagy-deficient, cancers attracted dendritic cells and T lymphocytes into the tumor bed. Suppression of autophagy inhibited the release of adenosine triphosphate (ATP) from dying tumor cells. Conversely, inhibition of extracellular ATP-degrading enzymes increased pericellular ATP in autophagy-deficient tumors, reestablished the recruitment of immune cells, and restored chemotherapeutic responses but only in immunocompetent hosts. Thus, autophagy is essential for the immunogenic release of ATP from dying cells, and increased extracellular ATP concentrations improve the efficacy of antineoplastic chemotherapies when autophagy is disabled.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Michaud, Mickael -- Martins, Isabelle -- Sukkurwala, Abdul Qader -- Adjemian, Sandy -- Ma, Yuting -- Pellegatti, Patrizia -- Shen, Shensi -- Kepp, Oliver -- Scoazec, Marie -- Mignot, Gregoire -- Rello-Varona, Santiago -- Tailler, Maximilien -- Menger, Laurie -- Vacchelli, Erika -- Galluzzi, Lorenzo -- Ghiringhelli, Francois -- di Virgilio, Francesco -- Zitvogel, Laurence -- Kroemer, Guido -- New York, N.Y. -- Science. 2011 Dec 16;334(6062):1573-7. doi: 10.1126/science.1208347.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM, U848, Villejuif, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22174255" target="_blank"〉PubMed〈/a〉

    An immunosurveillance mechanism controls cancer cell ploidy (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-09-29
    Description: Cancer cells accommodate multiple genetic and epigenetic alterations that initially activate intrinsic (cell-autonomous) and extrinsic (immune-mediated) oncosuppressive mechanisms. Only once these barriers to oncogenesis have been overcome can malignant growth proceed unrestrained. Tetraploidization can contribute to oncogenesis because hyperploid cells are genomically unstable. We report that hyperploid cancer cells become immunogenic because of a constitutive endoplasmic reticulum stress response resulting in the aberrant cell surface exposure of calreticulin. Hyperploid, calreticulin-exposing cancer cells readily proliferated in immunodeficient mice and conserved their increased DNA content. In contrast, hyperploid cells injected into immunocompetent mice generated tumors only after a delay, and such tumors exhibited reduced DNA content, endoplasmic reticulum stress, and calreticulin exposure. Our results unveil an immunosurveillance system that imposes immunoselection against hyperploidy in carcinogen- and oncogene-induced cancers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Senovilla, Laura -- Vitale, Ilio -- Martins, Isabelle -- Tailler, Maximilien -- Pailleret, Claire -- Michaud, Mickael -- Galluzzi, Lorenzo -- Adjemian, Sandy -- Kepp, Oliver -- Niso-Santano, Mireia -- Shen, Shensi -- Marino, Guillermo -- Criollo, Alfredo -- Boileve, Alice -- Job, Bastien -- Ladoire, Sylvain -- Ghiringhelli, Francois -- Sistigu, Antonella -- Yamazaki, Takahiro -- Rello-Varona, Santiago -- Locher, Clara -- Poirier-Colame, Vichnou -- Talbot, Monique -- Valent, Alexander -- Berardinelli, Francesco -- Antoccia, Antonio -- Ciccosanti, Fabiola -- Fimia, Gian Maria -- Piacentini, Mauro -- Fueyo, Antonio -- Messina, Nicole L -- Li, Ming -- Chan, Christopher J -- Sigl, Verena -- Pourcher, Guillaume -- Ruckenstuhl, Christoph -- Carmona-Gutierrez, Didac -- Lazar, Vladimir -- Penninger, Josef M -- Madeo, Frank -- Lopez-Otin, Carlos -- Smyth, Mark J -- Zitvogel, Laurence -- Castedo, Maria -- Kroemer, Guido -- New York, N.Y. -- Science. 2012 Sep 28;337(6102):1678-84.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM, U848, Villejuif, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23019653" target="_blank"〉PubMed〈/a〉

    Publication Date: 1978-04-21
    Description: Fractions from used crankcase oil enriched in polyaromatic hydrocarbons induced revertant colonies in Salmonella typhimurium strain TA 98 when activated by rat or trout liver extracts. The mutagenic activity was not due to benzopyrene or benzanthracene. Fractions from various crude and refined petroleums were nonmutagenic. Among various petroleum hydrocarbons entering inland and coastal waters, used crankcase oils may represent a major mutagenic burden.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Payne, J F -- Martins, I -- Rahimtula, A -- New York, N.Y. -- Science. 1978 Apr 21;200(4339):329-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/635591" target="_blank"〉PubMed〈/a〉

    Non-volant mammals from the Upper Paraná River Basin: a data set from a critical region for conservation in Brazil (2018)
    Wiley
    In: Ecology
    Details
    Publication Date: 2018-01-18
    Description: The data set represents the first attempt at a large-scale inventory of non-volant mammals, with potential applications to performing macroecological studies, developing conservation strategies, and undertaking population and community ecology research, but also to evaluate the ecological consequences of fragmentation and defaunation. Our objectives for compiling these data were to summarize information about inventories of non-volant mammals in the critically important area of the Upper Paraná River Basin by focusing on species richness and index of frequency of occurrence and to identify gaps in knowledge regarding non-volant mammal communities in order to guide future sampling efforts. The data set comprises studies on communities of non-volant mammals from 52 locations covering more than 1,000 km 2 and comprises portion of four Brazilian states in the Upper Paraná River Basin. We listed 81 species of non-volant mammals distributed among 58 genera, 22 families, and 9 orders. Rodentia (28 species) was the richest order, followed by Carnivora (17 spp.) and Didelphimorphia (15 spp.). The richest family was Cricetidae (20 spp.), followed by Didelphidae (15 spp.), and Dasypodidae and Felidae (six spp.). Considering national conservation status, one species are considered endangered and 16 vulnerable. Considering global conservation status, 7 species are considered vulnerable, 10 are considered near threatened, and 6 are data deficient. According to the index of frequency of occurrence, Myrmecophaga tridactyla was the most frequent species, occurring at 88.64% of all sites, while 25 species were considered very restricted, occurring in just 2.56% of all sites. In general, the non-volant mammal fauna was composed of mainly very restricted (VR, 25 species) and localized species (L, 25 species), which account for 61.7% of the known species, while 38.3% are restricted (R, 8 species), common (C, 16 species), and widespread (W, 7 species). Seven marsupials and five small rodents had their distributions extended in the central-south of Brazil. All of these species are considered data deficient or threatened, which highlights the importance of these records. No copyright restrictions are associated with the use of this data set. Please cite this data paper when the data are used in publications. We also request that researchers and teachers inform us of how they are using the data.

    Notes: Thus far it has been considered that hypersaline natural brines which are subjected to extreme solar heating, do not contain non-melanized yeast populations. Nevertheless we have isolated yeasts in eight different salterns worldwide, as well as from the Dead Sea, Enriquillo Lake (Dominican Republic) and the Great Salt Lake (Utah). Among the isolates obtained from hypersaline waters, Pichia guilliermondii, Debaryomyces hansenii, Yarrowia lipolytica and Candida parapsilosis are known contaminants of low water activity food, whereas Rhodosporidium sphaerocarpum, R. babjevae, Rhodotorula laryngis, Trichosporon mucoides, and a new species resembling C. glabrata were not known for their halotolerance and were identified for the first time in hypersaline habitats. Moreover, the ascomycetous yeast Metschnikowia bicuspidata, known to be a parasite of the brine shrimp, was isolated as a free-living form from the Great Salt Lake brine. In water rich in magnesium chloride (bitterns) from the La Trinitat salterns (Spain), two new species provisionally named C. atmosphaerica– like and P. philogaea– like were discovered.

    Topics: Biology
    Notes: Abstract Saccharomyces cerevisiae IGC4261, a brewing strain, transported fructose and sorbose but not glucose by a high-affinity, low-capacity proton symport. The symport was not subject to glucose repression and coexisted with the facilitated diffusion system for glucose, fructose, sorbose and other sugars. Transport by the symport was accumulative. The stoichiometry was one proton per molecule of fructose. Maltose acted as a non-competitive inhibitor.

    Inactivation of active glucose transport in Candida wickerhamii is triggered by exocellular glucose (1985)

    Notes: Abstract Under conditions of derepression the yeast Candida wickerhamii formed a high-affinity glucose proton symport. Glucose and glucose analogues induced inactivation of the glucose proton symport and its interconversion into a low-affinity facilitated diffusion system. The specific inactivation rate increased with the concentration of the inactivating sugar and did not obey saturation kinetics. This dependence was still pronounced at sugar concentrations far above saturation of the glucose transport systems. This suggested that the inactivation and interconversion mechanism was triggered by interaction of the inactivating sugar with receptor sites located on the cell surface.
