    Description: Inflatable pyloric cuffs and stomach tubes were implanted in rats. With the cuff inflated and a valve to limit intragastric pressure to that accompanying normal satiety, they drank only as much when they had been deprived of food for 12 hours as without inflation of the cuff. However, they overdrank with the cuff inflated when they had been water deprived for 12 hours. When 10 ml of milk was withdrawn from the stomach with the cuff inflated, compensatory drinking occurred. Further, compensatory drinking also occurred when milk escaped from the stomach into the duodenum. Satiety signals thus arise from the stomach.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deutsch, J A -- Young, W G -- Kalogeris, T J -- New York, N.Y. -- Science. 1978 Jul 14;201(4351):165-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663647" target="_blank"〉PubMed〈/a〉

    Description: Surgical removal of colon carcinomas leads to a decrease in the rate of incorporation of [14C]fucose into its endogenous acceptor in human serum; normal incorporation rates are attained within 14 days. A similar time course has been determined for alpha2- and alpha3-fucosyltransferase when either desialo- or desialodegalactofetuin are employed as exogenous acceptors. A correlation has also been seen between transferase activity and the therapeutic response of patients with breast cancer. These results indicate that the determination of fucosyltransferase activity can facilitate the diagnosis of neoplasia, and the success of surgery, chemotherapy, or radiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bauer, C H -- Reutter, W G -- Erhart, K P -- Kottgen, E -- Gerok, W -- New York, N.Y. -- Science. 1978 Sep 29;201(4362):1232-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/694511" target="_blank"〉PubMed〈/a〉

    Description: Prednisone treatment for infertility and subsequent pregnancy maintenance in humans resulted in a significant decrease in the birth weight of full-term infants and a marked increase in the percentage of newborn infants weighing 2500 grams or less, that is, "light for dates" in comparison to control offspring. A parallel experiment with mice indicated that the reduction of birth weight was caused by exposure to corticosteroids rather than to maternal disease or malfunction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reinisch, J M -- Simon, N G -- Karow, W G -- Gandelman, R -- New York, N.Y. -- Science. 1978 Oct 27;202(4366):436-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/705336" target="_blank"〉PubMed〈/a〉

    Description: The primary structure of lipopolysaccharide binding protein (LBP), a trace plasma protein that binds to the lipid A moiety of bacterial lipopolysaccharides (LPSs), was deduced by sequencing cloned complementary DNA. LBP shares sequence identity with another LPS binding protein found in granulocytes, bactericidal/permeability-increasing protein, and with cholesterol ester transport protein of the plasma. LBP may control the response to LPS under physiologic conditions by forming high-affinity complexes with LPS that bind to monocytes and macrophages, which then secrete tumor necrosis factor. The identification of this pathway for LPS-induced monocyte stimulation may aid in the development of treatments for diseases in which Gram-negative sepsis or endotoxemia are involved.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schumann, R R -- Leong, S R -- Flaggs, G W -- Gray, P W -- Wright, S D -- Mathison, J C -- Tobias, P S -- Ulevitch, R J -- AI 15136/AI/NIAID NIH HHS/ -- AI 25563/AI/NIAID NIH HHS/ -- GM 28485/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Sep 21;249(4975):1429-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Research Institute of Scripps Clinic, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2402637" target="_blank"〉PubMed〈/a〉

    Description: The apolipoprotein E type 4 allele (APOE-epsilon 4) is genetically associated with the common late onset familial and sporadic forms of Alzheimer's disease (AD). Risk for AD increased from 20% to 90% and mean age at onset decreased from 84 to 68 years with increasing number of APOE-epsilon 4 alleles in 42 families with late onset AD. Thus APOE-epsilon 4 gene dose is a major risk factor for late onset AD and, in these families, homozygosity for APOE-epsilon 4 was virtually sufficient to cause AD by age 80.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Corder, E H -- Saunders, A M -- Strittmatter, W J -- Schmechel, D E -- Gaskell, P C -- Small, G W -- Roses, A D -- Haines, J L -- Pericak-Vance, M A -- New York, N.Y. -- Science. 1993 Aug 13;261(5123):921-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Joseph and Kathleen Bryan Alzheimer's Disease Research Center, Duke University Medical Center, Durham, NC 27710.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8346443" target="_blank"〉PubMed〈/a〉

    Description: A synthetic combinatorial library containing 52,128,400 D-amino acid hexapeptides was used to identify a ligand for the mu opioid receptor. The peptide, Ac-rfwink-NH2, bears no resemblance to any known opioid peptide. Simulations using molecular dynamics, however, showed that three amino acid moieties have the same spatial orientation as the corresponding pharmacophoric groups of the opioid peptide PLO17. Ac-rfwink-NH2 was shown to be a potent agonist at the mu receptor and induced long-lasting analgesia in mice. Analgesia produced by intraperitoneally administered Ac-rfwink-NH2 was blocked by intracerebroventricular administration of naloxone, demonstrating that this peptide may cross the blood-brain barrier.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dooley, C T -- Chung, N N -- Wilkes, B C -- Schiller, P W -- Bidlack, J M -- Pasternak, G W -- Houghten, R A -- DA-000138/DA/NIDA NIH HHS/ -- DA-02615/DA/NIDA NIH HHS/ -- DA-03742/DA/NIDA NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Dec 23;266(5193):2019-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Torrey Pines Institute for Molecular Studies, San Diego, CA 92121.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7801131" target="_blank"〉PubMed〈/a〉

    Description: A new quantitative assay for studying the kinetics of vascular smooth muscle cells in vivo is reported. The assay was used to determine the specific activity of DNA from rabbit aortic smooth muscle cells stimulated to grow by removal of the endothelial layer. The specific activity of the DNA was correlated with the rate of tritiated thymidine incorporation as measured by autoradiography and with the rate of DNA synthesis as estimated by direct measurement of cellular proliferation. Smooth muscle cells exhibit a 24-hour latent period in vivo prior to DNA synthesis; the synthesis peaks at 48 hours and then rapidly declines. The decline in DNA synthesis is not related to endothelial regrowth, and may be of homeostatic significance in limiting luminal stenosis. The assay offers a rapid and reliable alternative to autoradiographic and morphometric techniques for evaluating growth kinetics and growth regulation in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldberg, I D -- Stemerman, M B -- Schnipper, L E -- Ransil, B J -- Crooks, G W -- Fuhro, R L -- New York, N.Y. -- Science. 1979 Aug 31;205(4409):920-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472713" target="_blank"〉PubMed〈/a〉

    Description: Low-frequency stimulation of hippocampal mossy fiber axons in zinc-deficient adult rats produced synaptic responses that declined in amplitude with successive stimuli. This response decrement is abnormal and suggests that the heavy deposits of zinc in mossy fiber boutons are important for synaptic transmission.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hesse, G W -- New York, N.Y. -- Science. 1979 Sep 7;205(4410):1005-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/224456" target="_blank"〉PubMed〈/a〉
