    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.

    Notes: The explosive performance of ∊-CL-20 was found to be approximately 14% greater than HMX as determined by cylinder expansion and tantalum plate acceleration experiments. This makes it the most powerful explosive ever tested at small volume expansions of the detonation products. In general CL-20 is more sensitive than HMX. However, the sensitivity of CL-20 to one-dimensional shock loading was found to be similar to HMX.

    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〉

    Topics: Chemistry and Pharmacology
    Notes: Wool fibers are comprised of proteins known as α-keratins and have a complex morphological structure. The major components of this structure, the cuticle and cortical cells, differ in the conformations of their peptide chains as well as their amino acid compositions. High quality Fourier transform Raman spectra of cortical and cuticle cells isolated from fine Merino wool fibers have been obtained. Raman spectroscopy has been shown to be sensitive to the differences in both secondary structure and amino acid composition. The cortical cells were found to be higher in α-helical content as compared to the cuticle cells, which had an increased disordered content. Specific information, consistent with amino acid analysis results, regarding cystine, tyrosine, tryptophan, and phenylalanine residues, were obtained for both the cortical and cuticle cells. In addition, the Raman spectra provided information about free thiol groups, amino acids residues with amide group side chains, and residues with protonated carboxyl group side chains. Middle ir transmission spectra of these isolated cells were also obtained. In comparison to the Raman data, the middle ir spectra were found to be not as rich in information. © 1997 John Wiley & Sons, Inc. Biopoly 42: 7-17, 1997

    Notes: A series of novel structured latex particles with interpenetrating polymer network (IPN) cores and glassy SAN shells were developed in an attempt to investigate the feasibility of these polymers as both toughening and damping agents in thermoplastics. The IPN cores were composed of one impact part (polybutadiene based) and one damping part (acrylic based, with Tg around +10°C). The particle morphologies of these polymers were determined by TEM. The glass transitions and mechanical behavior of the polymers were characterized from DMS. The effect of different components on the final core/shell particle morphologies and mechanical properties was studied. The mechanical behavior of core/shell particles with IPN cores was also compared with that of separate core/shell and multilayered core/shell particles. In addition, normal core/shell synthesis (rubbery part first then the glassy part) and inverted core/shell synthesis (glassy part first then the rubbery part) were performed to provide another access for morphology control. It was found that the core/shell latex particles with poly(butyl acrylate) based copolymers are more miscible than poly(ethylhexyl methacrylate)-based copolymers. The high grafting efficiency of poly(butyl acrylate) plays an important role in governing phase miscibility. The latex particles synthesized by the inverted core/shell mode showed higher miscibility than the normal synthesized ones. © 1997 John Wiley & Sons, Inc.

    Notes: The particle sizes and their size distributions of latexes from the dispersion polymerization of styrene using a small amount of ω-methoxy poly(ethylene oxide)n undecyl-α-methacrylate macromonomer (PEO-R-MA-40) as a polymerizable stabilizer in ethanol-water media have been studied. Monodisperse or/and nearly monodisperse latex particles from 0.1 to 1 μm in diameter were readily obtained. The diameter of latex particles follows the relationship Dvad ∝ θ0.33 [PEO-R-MA-40]-0.60 [styrene]01.02 [AIBN]o-0.09, where θ is the fractional conversion of styrene. Except for the styrene concentration dependency, this relationship is in excellent agreement with the model developed by Paine11 and modified by Kawaguchi et al.13 When the surface composition of the grafted PEO macromonomer on the latex particles exceeded 16% as analyzed by X-ray photoelectron spectroscopy (XPS), the particles were nearly monodisperse. In terms of polymerization, this occurred around 18% conversion of styrene. Beyond this critical state of polymerization, the latex particles grew bigger with more PEO macromonomer-styrene copolymers situated on the particle surface. The effect of various factors on the particle size distribution is also discussed. © 1997 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 35: 3575-3583, 1997
