    Notes: Summary The therapeutic effects of vitamin D analogs, 1,24(R)-dihydroxycholecalciferol [1,24(R)(OH)2D3], 1,24(S)-dihydroxycholecalciferol [1,24(S)(OH)2D3], and 1,25-dihydroxycholecalciferol [1,25(OH)2D3] on immobilization osteoporosis were studied in rats. The right hind limb was immobilized through application of a plaster cast following the section of the sciatic nerve. The left hind limb was intact. Vitamin D analogs were orally administered for 6 weeks at dose levels of 0.02 and 0.10µg/kg/day, respectively. The mean lengths of the immobilized femurs were not significantly different from those of the intact femurs in all the experimental groups. In the immobilized femur of animals treated with 1,24(R)(OH)2D3, 0.10µg/kg, dry and ash weights were heavier and calcium and phosphorus contents greater than those in the nontreated group. Furthermore, the amount of calcified bone mass and the cortical thickness of the femurs of the immobilized limb in 1,24(R)(OH)2D3-treated animals were greater than those in the nontreated animals. Treatment with 1,25(OH)2D3 at 0.10µg/kg caused an increase of the bone mass in both immobilized and intact femurs when compared with those of the control group. It was concluded that the administration of 1,24(R)(OH)2D3 diminished the effect of immobilization in the development of osteoporosis without any side effects.

    Notes: Summary The study describes the SEM appearances of endosteal and periosteal surfaces of anorganic femoral diaphyses from 16-month-old normal and castrate male rats. Different types of surfaces could be recognized in both groups. Percentage areas occupied by each surface type were analyzed with a Ladd Data Analyzing Digitizer. Endosteal surfaces were composed of significantly more (P〈0.05) incompletely mineralized, forming surface and significantly less (P〈0.05) completely mineralized, resting surface in castrates than in controls. Both endosteal and periosteal surfaces from experimental bone demonstrated significantly more (P〈0.05) osteoblast lucunae than did control surfaces, and vascular canal entrances were significantly wider (P〈0.001) on castrate endosteal surfaces than on control endosteal surfaces. There was a greater proportion of small nodule forming surface/large nodule forming surface in castrate endosteal bone than in control, and a greater proportion prolonged resting surface/fibrous resting surface in control periosteal bone than in castrate. The results indicate that, when viewed in the SEM, anorganic endosteal and periosteal bone surfaces from femoral diaphyses of old castrate male rats demonstrate appearances characteristic of changes in bone turnover that occur with osteoporosis.

    Notes: Summary Isocaloric and isovolemic amounts of protein (casein), fat (intralipid) and carbohydrate (saccharose) and an isovolemic control solution of water were administered intragastrically to conscious rats. The plasma CCK levels, determined by a sensitive and specific radioimmunoassay, showed an increment of 6.3±0.6, 2.7±0.5, 1.7±0.4 and −0.9±0.4 pM, respectively (basal value 2.5±0.3 pM). The threshold increment of plasma CCK to stimulate pancreatic enzyme secretion by exogenous CCK was found to be 1.5 pM. It is therefore concluded that casein is a potent stimulus for CCK secretion and pancreatic secretion, but that fat and even carbohydrate, although less potent, also produce a CCK increment above the threshold for pancreatic secretion.

    Notes: Summary Various parts of the skeleton of normal and osteoporotic rats were compared with respect to their dry weight, ash weight, and calcium content when the bones were cleaned byDermestes maculatus beetles or manually. Both techniques gave similar results. This was also true when whole body calcium measured by neutron activation and total skeletal calcium from bones cleaned by the beetles were compared. Thus dermestid beetles are useful as a technique to clean bones, especially for the parts of the skeleton which are difficult to dissect by hand.

    Effects of castration on the bone structure of male rats: A model of osteoporosis (1980)

    Notes: Summary Forty young (23-day-old) and thirty old (1-year-old) male rats were castrated and sacrificed with controls at intervals up to 18 months of age. No differences were observed between femurs or mandibles of rats castrated at 23 days and those of controls. Year-old castrate rats developed femoral osteoporosis after 2 months, which became more pronounced 4 months after castration. This was characterized by reductions in femoral density, dry weight, dry weight per unit length, and ash weight, and by the appearance of resorption cavities in diaphyseal walls and a sparsity of trabeculae in metaphyses and epiphyses of castrate femurs. These results indicate that the year-old castrate male rat may be a valuable experimental model for studies of the treatment of osteoporosis.

    Role of parathyroid hormone and 1,25-dihydroxyvitamin D3 in the development of osteopenia in oophorectomized rats (1982)
    Springer
    Calcified tissue international 34 (1982), S. 510-514

    ISSN: 1432-0827
    Keywords: Rats ; Osteopenia of oophorectomy ; 1,25-Dihydroxyvitamin D3 ; Parathyroid hormone ; Osteoporosis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine , Physics
    Notes: Summary The effect of ovarian insufficiency on calcium metabolism has been thought to involve an increased bone resorptive effect of parathyroid hormone and possible impaired synthesis of 1,25-dihydroxyvitamin D3. In the present study a rat model allowing for controlled serum levels of parathyroid hormone and 1,25-dihydroxyvitamin D3 was used. Oophorectomy in this species is associated with increased serum levels of 1,25-dihydroxyvitamin D3 and decreased bone mass. Although thyroparathyroidectomy increased bone mass, an increased sensitivity of bone to parathyroid hormone in oophorectomized rats was not observed. Thus the development of the osteopenia did not seem to be related to increased parathyroid hormone sensitivity or to reduced levels of 1,25-dihydroxyvitamin D3. Exogenous 1,25-dihydroxyvitamin D3 increased bone mass in oophorectomized as well as intact rats. Intestinal calcium transport was increased by moderate doses of 1,25-dihydroxyvitamin D3. Intestinal calcium transport was also reduced by thyroparathyroidectomy and increased by the administration of parathyroid extract. A tendency for increased accumulation of 1,25-dihydroxyvitamin D3 in blood in oophorectomized rats has been noted. It is suggested that the tendency to hypercalcemia in ovarian-insufficient females given 1-hydroxylated vitamin D compounds may be related to a diminished metabolism of 1,25-dihydroxyvitamin D3.

    Notes: Summary The occurrence of matrix vesicles in the maxillary bone of normal young and adult rats was demonstrated by both ultrastructural and enzymatic studies. Transmission electron microscopy revealed that the vesicles are invested in trilaminar membranes. Occasionally, crystals were found both within the vesicles and in the surrounding matrix. Separated fractions of vesicles, membranes, and cells were studied biochemically. The amounts of vesicular protein and enzymatic activity per gram bone in the adult rats were significantly lower than in the young. This coincides with the higher number of vesicles observed in the TEM specimens of young rats when compared to that in the old ones. The specific activities of all enzymes examined in the three bone fractions obtained from both young and adult rats were similar. This indicates that no significant difference exists in the enzymatic characteristics of matrix vesicles from the maxillary bone of young and adult rats.

    Cyclophosphamide-induced changes in rodent odontogenesis (1983)

    Notes: Summary Cyclophosphamide-induced changes in rodent odontogenesis were investigated by light and electron microscopy in four-day-old Sprague Dawley rats given one injection of 40 mg/kg of body weight of cyclophosphamide and killed at intervals of one hour, one day, one week and two weeks. Incisor and molar teeth were dissected from the animals, fixed in 2.0% glutaraldehyde in 0.1 M sodium cacodylate with 3.4% sucrose, and subsequently some were incubated for alkaline phosphatase reaction, and embedded in Spurr's medium for sectioning at light- and electron-microscopic levels. From three days a cell-sparse zone was created in the pulp in the growing end of the tooth and progressive cellular changes were observed which became more severe in the one-week and two-week specimens. Subodontoblast and adjacent pulpal cells were the most affected showing nuclear changes, damage to, or loss of, organelles, and inclusion bodies. Odontogenic epithelium was less affected and odontoblasts appeared to be unaffected by the drug. A new irregular matrix was laid down in the defect area and seemed to be the product of depolarized odontoblasts. This new matrix showed alkaline phosphatase activity, as did the cells embedded in it, and later it became mineralized. It is speculated that the polarity of odontoblasts might be maintained by an intact subodontoblastic layer; when this is lost the odontoblasts become depolarized and capable of secreting matrix from both ends.

    Myosin content and vasoconstrictive ability of the proximal and distal (renin-positive) segments of the preglomerular arteriole (1987)

    Notes: Summary The PAP-technique and antibodies to myosin were used to demonstrate the prerequisites for vasoconstriction in the juxtaglomerular part of the preglomerular arteriole as compared with its proximal segment in rats and mice. In contrast with the myosin-positive/renin-negative proximal part of the afferent arteriole no myosin-like activity could be demonstrated in its distal, renin-positive part. In accordance, no thick myofilaments were found in fully differentiated juxtaglomerular epithelioid cells replete with mature secretory granules. Stimulation of the renin-angiotensin system was followed by an increase of the reninpositive/myosin-negative portions of the preglomerular arteriole. Marked interspecies and internephron variations in the length of this vessel segment under control and stimulated conditions were observed. The juxtaglomerular part of the preglomerular arteriole close to the macula densa seems therefore to have only limited capabilities for vasoconstriction. This finding may be of importance regarding the tubulo-glomerular feedback, a mechanism allegedly triggered by the so-called ‘macula densa-signal’. It is suggested that this non-contractile segment of the afferent arteriole may represent the renal vascular receptor responsible for the increase of renin secretion during pressure reduction. Unlike the afferent arterioles, most of the efferent arterioles showed the highest level of their weak but distinct myosin-like immunoreactivity in the juxtaglomerular region, indicating some efferent juxtaglomerular vasoconstrictive ability.

    Notes: Summary Quantitative macroscopic, light-microscopic and electron-microscopic studies were performed on the small intestine of fasted and non-fasted adult, male Sprague-Dawley rats. In non-fasted rats the small intestine was longer than in fasted rats. Due to the presence of villi the surface area in the duodenum and the jejunum was enlarged about six times. The microvilli on the villous crests caused a surface enlargement by 13 times in the duodenum (value corrected for overestimation due to section thickness), and 19 times in the jejunum of the fasted rats. At the base of the villi these values were about 50% lower. It was calculated that, in the fasted rats, the total enlargement of the luminal surface area — due to villi and microvilli — was 63 times in the duodenum and 81 times in the jejunum (corrected for section thickness). Differences between the villous crest epithelium and the villous base epithelium were also found with regard to the mean cell height, and the volume densities of the absorptive cell nuclei, the mitochondria, and the paracellular channels.

    Notes: Abstract A first exploration of applications of ecological niche modeling and geographic distributional prediction to endangered species protection is developed. Foci of richness of endangered bird species are identified in coastal California and along the southern fringe of the United States. Species included on the Endangered Species List on the basis of peripheral populations inflate these concentrations considerably. Species without protection in the US National Park System are focused particularly in peninsular Florida. Application of this methodology to additional taxa and regions holds promise for diverse conservation applications.

    Notes: Abstract The destruction of submerged vegetation by common carp, Cyprinus carpio L. is tested in six enclosures with different biomass (kg ha−1) of carp in a marsh of the Camargue, southern France. After 71 days, a strong negative relationship was found between the biomass of carp and the amount of aquatic vegetation present in the enclosures. The results are compared with similar studies in the United States. The absence of problem of vegetation destruction by carp in Europe, in contrast to North America, may be explained by lower biomass of these populations in Europe, and by a higher weight of carp in North America.

    Notes: Abstract The purpose of this study was to examine the colonization and succession of benthic macroinvertebrates in shallow areas (〈7 m) of Lake Anna, a new mainstream impoundment in the southeastern U.S.A. Benthic macroinvertebrates were sampled for the first three years after filling by means of artificial substrates placed on the bottom and retrieved with SCUBA. Lake Anna was well colonized by benthic macroinvertebrates during the summer season immediately after impoundment. The total density of organisms increased in each of the first three years. Major changes in the fauna occurred between the first and second years, but the changes between the second and third years were more subtle. The fauna could be divided into two distinct groups based upon the time when the organisms were most consistently abundant. The first colonizers appeared to be dependent upon the components of the former terrestrial ecosystem for food and habitat. As autochthonous factors began to regulate succession, diversity increased and the dominant species shifted to an assemblage of second colonizers. These factors included: (1) decomposition of terrestrial vegetation and detritus leaving bare substrate, (2) sedimentation, (3) improved food quality of the organic matter in the sediment because of ingestion and egestion by the organisms themselves, (4) increased plankton populations, and (5) appearance of macrophytes. As the second colonizers became firmly established in the third year, distinct patterns of spatial distribution began to appear among species with similar niches.

    Notes: Abstract A survey of dermatophytes isolated from patients seeking medical advice was made from 1982 to 1984 in the United States. The survey included 59 locations with data from 49 cities and one state. Listing of the isolated dermatophytes and the frequency given by percentage of total follows: Trichophyton rubrum 46.8%, T. tonsurans 33.3%, T. mentagrophytes 10.1%, Microsporum canis 4.5%, Epidermophyton floccosum 3,5%, M. gypseum and T. verrucosum both 0.7%, M. audouinii and T. terrestre both 0.1%, and T. violaceum 0.06%. No isolations of M. ferrugineum or T. schoenleinii were reported. Temporal increases were observed for frequencies of T. mentagrophytes, T. tonsurans and M. canis, and decreases occurred for frequencies of E. floccosum and T. rubrum when the data from this survey were compared by the goodness of fit test to data of the 1979 to 1981 survey. The percent of dermatophyte isolations identified as T. tonsurans correlated significantly with the percentage of blacks in cities of 100000 or more people.

    Notes: Summary The effect of isoproterenol (IPR) on acinar cell mitoses was studied in regenerating submandibular glands of the rat following partial extirpation. In controls, mitoses of acinar cells were markedly higher on the cut surface (reactive zone) than in the remainder of the gland through 10 ds post-operation. In experimental animals by 5 ds, a burst of mitoses of acinar cells was seen in all areas of the gland except the reactive zone. In the reactive zone, IPR appears to suppress or inhibit the induced mitoses seen in controls.

    Notes: Summary The rates of axoplasmic transport were studied in the corticospinal tract of the rat by injecting tritiated proline into the sensory-motor cortex and subsequently analyzing the distribution of incorporated label in the spinal cord at intervals after injection. A mathematical model of the anatomy of the corticospinal tract was developed and used in analysis of the data. The rate of a fast component was calculated to be 240–420 mm per day, which is comparable with rates of fast components in the peripheral nervous system (PNS), but considerably greater than rates in other tracts in the central nervous system. A slow component was calculated to have a transport rate of 3–8 mm per day which is greater than rates found either in the CNS or PNS. This higher rate may be related to the greater length of the corticospinal tract as compared to other CNS tracts studied.

    Ultrastructural evidence of gonadotrophin release from castration cells following injection of LHRH in the rat (1982)

    Notes: Summary To examine the morphological evidence of the nature of hormone release from castration cells the author gonadectomized neonatal male and female rats. Twenty-eight days after the operation the animals were pretreated with estrogen, progesterone, or estrogen and progesterone in combination, every other day for one week, and then injected with LHRH 30 min before sacrifice. The administration of LHRH elevated remarkably the serum levels of gonadotrophins (LH and FSH) of neonatally gonadectomized rats. The steroid-pretreated animals showed higher serum levels of gonadotrophins than controls. Simultaneously, active exocytosis of secretory granules was observed in the hypertrophic gonadotrophs or castration cells of neonatally gonadectomized and steroid-treated rats following the injection of LHRH. These results indicate that hypertrophic gonadotrophs or castration cells also release hormone(s) by exocytosis of secretory granules.

    Control of synaptic strength by glial TNFalpha (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-03-23
    Description: Activity-dependent modulation of synaptic efficacy in the brain contributes to neural circuit development and experience-dependent plasticity. Although glia are affected by activity and ensheathe synapses, their influence on synaptic strength has largely been ignored. Here, we show that a protein produced by glia, tumor necrosis factor alpha (TNFalpha), enhances synaptic efficacy by increasing surface expression of AMPA receptors. Preventing the actions of endogenous TNFalpha has the opposite effects. Thus, the continual presence of TNFalpha is required for preservation of synaptic strength at excitatory synapses. Through its effects on AMPA receptor trafficking, TNFalpha may play roles in synaptic plasticity and modulating responses to neural injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beattie, Eric C -- Stellwagen, David -- Morishita, Wade -- Bresnahan, Jacqueline C -- Ha, Byeong Keun -- Von Zastrow, Mark -- Beattie, Michael S -- Malenka, Robert C -- DA00439/DA/NIDA NIH HHS/ -- MH063394/MH/NIMH NIH HHS/ -- NS 31193/NS/NINDS NIH HHS/ -- NS38079/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2002 Mar 22;295(5563):2282-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Nancy Pritzker Laboratory, Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Palo Alto, CA 94304, USA. beattie.2@osu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11910117" target="_blank"〉PubMed〈/a〉

    Description: Despite recent genetic evidence and the promise of individualized medicine, there is a continuing interest in using self-identified categories of race and ethnicity as variables in scientific and medical research. The U.S. Food and Drug Administration recently proposed a standardized approach for the collection of race and ethnicity data in clinical trials. We believe that this move fails to acknowledge new scientific data and recommend that relevant data from individuals be collected and used rather than broad group statistics. We also encourage that increased funding be committed to this important issue.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haga, Susanne B -- Venter, J Craig -- New York, N.Y. -- Science. 2003 Jul 25;301(5632):466.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for the Advancement of Genomics, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12881555" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-01
    Description: The use of Internet references in academic literature is common, and Internet references are frequently inaccessible. The extent of Internet referencing and Internet reference activity in medical or scientific publications was systematically examined in more than 1000 articles published between 2000 and 2003 in the New England Journal of Medicine, The Journal of the American Medical Association, and Science. Internet references accounted for 2.6% of all references (672/25548) and in articles 27 months old, 13% of Internet references were inactive. Publishers, librarians, and readers need to reassess policies, archiving systems, and other resources for addressing Internet reference attrition to prevent further information loss.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dellavalle, Robert P -- Hester, Eric J -- Heilig, Lauren F -- Drake, Amanda L -- Kuntzman, Jeff W -- Graber, Marla -- Schilling, Lisa M -- K-07 CA92550/CA/NCI NIH HHS/ -- R25 CA49981/CA/NCI NIH HHS/ -- T32 AR07411/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Oct 31;302(5646):787-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Veterans Affairs Medical Center, Denver, CO 80220, USA. robert.dellavalle@uchsc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14593153" target="_blank"〉PubMed〈/a〉

    Facilitation of spinal NMDA receptor currents by spillover of synaptically released glycine (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-06-28
    Description: In the mammalian CNS, N-methyl-D-aspartate (NMDA) receptors serve prominent roles in many physiological and pathophysiological processes including pain transmission. For full activation, NMDA receptors require the binding of glycine. It is not known whether the brain uses changes in extracellular glycine to modulate synaptic NMDA responses. Here, we show that synaptically released glycine facilitates NMDA receptor currents in the superficial dorsal horn, an area critically involved in pain processing. During high presynaptic activity, glycine released from inhibitory interneurons escapes the synaptic cleft and reaches nearby NMDA receptors by so-called spillover. In vivo, this process may contribute to the development of inflammatory hyperalgesia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ahmadi, Seifollah -- Muth-Selbach, Uta -- Lauterbach, Andreas -- Lipfert, Peter -- Neuhuber, Winfried L -- Zeilhofer, Hanns Ulrich -- New York, N.Y. -- Science. 2003 Jun 27;300(5628):2094-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut fur Experimentelle und Klinische Pharmakologie und Toxikologie, Universitat Erlangen-Nurnberg, Fahrstrasse 17, D-91054 Erlangen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12829784" target="_blank"〉PubMed〈/a〉

    Derepression of BDNF transcription involves calcium-dependent phosphorylation of MeCP2 (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-01
    Description: Mutations in MeCP2, which encodes a protein that has been proposed to function as a global transcriptional repressor, are the cause of Rett syndrome (RT T), an X-linked progressive neurological disorder. Although the selective inactivation of MeCP2 in neurons is sufficient to confer a Rett-like phenotype in mice, the specific functions of MeCP2 in postmitotic neurons are not known. We find that MeCP2 binds selectively to BDNF promoter III and functions to repress expression of the BDNF gene. Membrane depolarization triggers the calcium-dependent phosphorylation and release of MeCP2 from BDNF promoter III, thereby facilitating transcription. These studies indicate that MeCP2 plays a key role in the control of neuronal activity-dependent gene regulation and suggest that the deregulation of this process may underlie the pathology of RT T.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Wen G -- Chang, Qiang -- Lin, Yingxi -- Meissner, Alexander -- West, Anne E -- Griffith, Eric C -- Jaenisch, Rudolf -- Greenberg, Michael E -- HD 18655/HD/NICHD NIH HHS/ -- NS28829/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2003 Oct 31;302(5646):885-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neuroscience, Children's Hospital, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14593183" target="_blank"〉PubMed〈/a〉

    Experience strengthening transmission by driving AMPA receptors into synapses (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-03-08
    Description: The mechanisms underlying experience-dependent plasticity in the brain may depend on the AMPA subclass of glutamate receptors (AMPA-Rs). We examined the trafficking of AMPA-Rs into synapses in the developing rat barrel cortex. In vivo gene delivery was combined with in vitro recordings to show that experience drives recombinant GluR1, an AMPA-R subunit, into synapses formed between layer 4 and layer 2/3 neurons. Moreover, expression of the GluR1 cytoplasmic tail, a construct that inhibits synaptic delivery of endogenous AMPA-Rs during long-term potentiation, blocked experience-driven synaptic potentiation. In general, synaptic incorporation of AMPA-Rs in vivo conforms to rules identified in vitro and contributes to plasticity driven by natural stimuli in the mammalian brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takahashi, Takuya -- Svoboda, Karel -- Malinow, Roberto -- NS032827/NS/NINDS NIH HHS/ -- NS038259/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2003 Mar 7;299(5612):1585-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Jones Laboratory, Cold Spring Harbor Laboratory, Cold Spring Harbor, NY 11724, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12624270" target="_blank"〉PubMed〈/a〉

With the Society for Neuroscience meeting routinely packing in about 25,000 people, some neuroscientists complain about long lines and related inconveniences. But others say that the best reason to go to the meeting is precisely because it's so huge and integrates the ever-growing number of subdisciplines in the field.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Helmuth, L -- New York, N.Y. -- Science. 2000 Oct 27;290(5492):698-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11184193" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)

    Publication Date: 2001-02-24
    Description: The U.S. Department of Agriculture requested comments earlier this year to help it decide whether to adopt a formal definition of "distress" as part of its responsibilities under the Animal Welfare Act. But the 2600 pieces of advice it received during a 4-month period that ended earlier this month suggest that its job won't be easy. The comments highlight a deep split between animal activists, who see the potential new regulations as a step toward eliminating all painful procedures, and most researchers, who say that the present system is working well and that no major changes are needed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Holden, C -- New York, N.Y. -- Science. 2000 Nov 24;290(5496):1474-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11185495" target="_blank"〉PubMed〈/a〉

    Description: Experts in the young field of violence epidemiology blame guns and crack cocaine for America's deadly crime surge in the early 1990s. Explaining the subsequent decline in violent crime rates has been more difficult, however. Some of the factors that seem to have helped squelch crime could be temporary, such as low unemployment rates. But others, including a growing intolerance for violence as a means of settling interpersonal disputes, seem to have become cultural norms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Helmuth, L -- New York, N.Y. -- Science. 2000 Jul 28;289(5479):582-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10939973" target="_blank"〉PubMed〈/a〉

    Publication Date: 2000-08-05
    Description: Researchers have uncovered new evidence about the long-range, and potentially long-term, ecological damage being wrought by an invasive species of fire ant. The red imported fire ant Solenopsis invicta displaces other ant species and upsets the structures of native communities of ants--disruptions that appear to be permanent, they report in the July issue of Ecology Letters. The drop in biodiversity could represent a significant loss, experts note, because of the critical role ants play in recycling nutrients and other biological material.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pennisi, E -- New York, N.Y. -- Science. 2000 Jul 14;289(5477):231.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10917841" target="_blank"〉PubMed〈/a〉

    Role for rapid dendritic protein synthesis in hippocampal mGluR-dependent long-term depression (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-05-20
    Description: A hippocampal pyramidal neuron receives more than 10(4) excitatory glutamatergic synapses. Many of these synapses contain the molecular machinery for messenger RNA translation, suggesting that the protein complement (and thus function) of each synapse can be regulated on the basis of activity. Here, local postsynaptic protein synthesis, triggered by synaptic activation of metabotropic glutamate receptors, was found to modify synaptic transmission within minutes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huber, K M -- Kayser, M S -- Bear, M F -- New York, N.Y. -- Science. 2000 May 19;288(5469):1254-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Neuroscience, Brown University, Providence, RI 02912, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10818003" target="_blank"〉PubMed〈/a〉

    Learning-induced LTP in neocortex (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-10-20
    Description: The hypothesis that learning occurs through long-term potentiation (LTP)- and long-term depression (LTD)-like mechanisms is widely held but unproven. This hypothesis makes three assumptions: Synapses are modifiable, they modify with learning, and they strengthen through an LTP-like mechanism. We previously established the ability for synaptic modification and a synaptic strengthening with motor skill learning in horizontal connections of the rat motor cortex (MI). Here we investigated whether learning strengthened these connections through LTP. We demonstrated that synapses in the trained MI were near the ceiling of their modification range, compared with the untrained MI, but the range of synaptic modification was not affected by learning. In the trained MI, LTP was markedly reduced and LTD was enhanced. These results are consistent with the use of LTP to strengthen synapses during learning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rioult-Pedotti, M S -- Friedman, D -- Donoghue, J P -- NS27164/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2000 Oct 20;290(5491):533-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, Brown University, Providence, RI 02912, USA. mengia_rioult@brown.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11039938" target="_blank"〉PubMed〈/a〉
