    Description: Familial combined hyperlipidemia (FCHL) is a common inherited lipid disorder, affecting 1 to 2 percent of the population in Westernized societies. Individuals with FCHL have large quantities of very low density lipoprotein (VLDL) and low density lipoprotein (LDL) and develop premature coronary heart disease. A mouse model displaying some of the features of FCHL was created by crossing mice carrying the human apolipoprotein C-III (APOC3) transgene with mice deficient in the LDL receptor. A synergistic interaction between the apolipoprotein C-III and the LDL receptor defects produced large quantities of VLDL and LDL and enhanced the development of atherosclerosis. This mouse model may provide clues to the origin of human FCHL.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Masucci-Magoulas, L -- Goldberg, I J -- Bisgaier, C L -- Serajuddin, H -- Francone, O L -- Breslow, J L -- Tall, A R -- HL 21006/HL/NHLBI NIH HHS/ -- HL 54591/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1997 Jan 17;275(5298):391-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Columbia University, 630 West 168 Street, New York, NY 10032, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8994037" target="_blank"〉PubMed〈/a〉

    Notes: PSP94 has shown potential to be a serum biomarker for evaluating prostate cancer. Studies of the epitope structure is crucial for this endeavour. In this article, we have used 15 different monoclonal antibodies (MAb) to analyse the epitope structure of PSP94 and to compare with the results obtained from our previous work using polyclonal antibody and recombinant PSP94. Firstly, we determined the relative activities of the 15 MAb population by direct and competitive ELISA. The two predominant MAbs (MAb PSP-6 and -19) in 15 MAbs were selected for further studies of the epitope structure. By comparing the binding activities of recombinant GST-PSP94 and natural PSP94 with MAbs, and by comparing their affinity with MAbs in an in vitro denaturing experiment, PSP94 was shown to have a similar, prevalently linear epitope structure as we demonstrated by polyclonal antibody. Using recombinant GST fusion protein with PSP94 and with each half of the N- and C-terminal 47 amino acids (GST-PSP-N47/C47) in E. coli cells, the different epitopes recognized by 15 monoclonal antibodies were delineated and the polar distribution of the epitope structure of PSP94 was characterized. Results of direct ELISA of recombinant N47 and C47 and their competitive binding against natural PSP94 (competitive ELISA) showed that the N- and C-termini represent the immuno-dominant and immuno-recessive area separately. A majority of the monoclonal antibodies (12/15) showed preferential binding of the N-terminal sequence of the PSP94 protein. Using GST-PSP-N47 as a standard protein, an epitope map of the 15 monoclonal antibodies was obtained. The results of this study will help to define the clinical utility of PSP94. J. Cell.

    Description: Multiple endocrine neoplasia-type 1 (MEN1) is an autosomal dominant familial cancer syndrome characterized by tumors in parathyroids, enteropancreatic endocrine tissues, and the anterior pituitary. DNA sequencing from a previously identified minimal interval on chromosome 11q13 identified several candidate genes, one of which contained 12 different frameshift, nonsense, missense, and in-frame deletion mutations in 14 probands from 15 families. The MEN1 gene contains 10 exons and encodes a ubiquitously expressed 2.8-kilobase transcript. The predicted 610-amino acid protein product, termed menin, exhibits no apparent similarities to any previously known proteins. The identification of MEN1 will enable improved understanding of the mechanism of endocrine tumorigenesis and should facilitate early diagnosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chandrasekharappa, S C -- Guru, S C -- Manickam, P -- Olufemi, S E -- Collins, F S -- Emmert-Buck, M R -- Debelenko, L V -- Zhuang, Z -- Lubensky, I A -- Liotta, L A -- Crabtree, J S -- Wang, Y -- Roe, B A -- Weisemann, J -- Boguski, M S -- Agarwal, S K -- Kester, M B -- Kim, Y S -- Heppner, C -- Dong, Q -- Spiegel, A M -- Burns, A L -- Marx, S J -- New York, N.Y. -- Science. 1997 Apr 18;276(5311):404-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Gene Transfer, National Human Genome Research Institute (NHGRI), National Institutes of Health (NIH), Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9103196" target="_blank"〉PubMed〈/a〉

    Description: Glial cell line-derived neurotrophic factor (GDNF) supports growth and survival of dopaminergic (DA) neurons. A replication-defective adenoviral (Ad) vector encoding human GDNF injected near the rat substantia nigra was found to protect DA neurons from the progressive degeneration induced by the neurotoxin 6-hydroxydopamine (6-OHDA) injected into the striatum. Ad GDNF gene therapy reduced loss of DA neurons approximately threefold 6 weeks after 6-OHDA lesion, as compared with no treatment or injection of Ad lacZ or Ad mGDNF (encoding a biologically inactive deletion mutant GDNF). These results suggest that Ad vector-mediated GDNF gene therapy may slow the DA neuronal cell loss in humans with Parkinson's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Choi-Lundberg, D L -- Lin, Q -- Chang, Y N -- Chiang, Y L -- Hay, C M -- Mohajeri, H -- Davidson, B L -- Bohn, M C -- NS31957/NS/NINDS NIH HHS/ -- T32AG00107/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1997 Feb 7;275(5301):838-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology and Anatomy, University of Rochester, Box 603, 601 Elmwood Avenue, Rochester, NY 14642, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9012352" target="_blank"〉PubMed〈/a〉

    Description: If hydrothermal Systems existed on Mars, hydration of crustal rocks may have had the potential to affect the water budget of the planet. We have conducted geochemical model calculations to investigate the relative roles of host rock composition, temperature, water-to-rock ratio, and initial fluid oxygen fugacity on the mineralogy of hydrothermal alteration assemblages, as well as the effectiveness of alteration to store water in the crust as hydrous minerals. In order to place calculations for Mars in perspective, models of hydrothermal alteration of three genetically related Icelandic volcanics (a basalt, andesite, and rhyolite) are presented, together with results for compositions based on SNC meteorite samples (Shergotty and Chassigny). Temperatures from 150 degrees C to 250 degrees C, water-to-rock ratios from 0.1 to 1000, and two initial fluid oxygen fugacities are considered in the models. Model results for water-to-rock ratios less than 10 are emphasized because they are likely to be more applicable to Mars. In accord with studies of low-grade alteration of terrestrial rocks, we find that the major controls on hydrous mineral production are host rock composition and temperature. Over the range of conditions considered, the alteration of Shergotty shows the greatest potential for storing water as hydrous minerals, and the alteration of Icelandic rhyolite has the lowest potential.

    Notes: Plantwide control involves the systems and strategies required to control an entire chemical plant consisting of many interconnected unit operations. A general heuristic design procedure is presented that generates an effective plantwide control structure for an entire complex process flowsheet and not simply individual units. The nine steps of the proposed procedure center around the fundamental principles of plantwide control: energy management; production rate; product quality; operational, environmental and safety constraints; liquid-level and gas-pressure inventories; makeup of reactants; component balances; and economic or process optimization. Application of the procedure is illustrated with three industrial examples: the vinyl acetate monomer process, the Eastman plantwide-control process, and the HDA process.

    Notes: Cosolvents offer a sensitive tool to tailor equilibria, rates or yields of chemical reactions in supercritical fluid solvents. The tautomeric equilibrium of a Schiff base was chosen as a model system, and small amounts of protic cosolvents shift the position of tautomeric equilibria. The equilibrium was tuned from essentially one tautomer to another by modifying the solvent of pure SCF ethane with less than 2 mol % hexafluoroisopropanol cosolvent. The equilibrium constant was a function of cosolvent concentration and mixture density. A chemical-physical model of equilibrium constants deviates from the measured values in the near-critical region, which may have been caused by local composition enhancement of cosolvent around the Schiff base. Decrease in the degree of hydrogen bonding with pressure or density affects the keto-enol equilibria by decreasing the amount of the keto formation. Thus, solution density, as well as the degree of hydrogen bonding, is manipulated to tune the position of tautomeric equilibria.
