Laminin Receptors For Neurite Formation, H. K. Kleinman, Roy C. Ogle, F. B. Cannon, C. D. Little, T. M. Sweeney, L. Luckenbill-Edds

School of Medical Diagnostics & Translational Sciences Publications

Laminin, a basement membrane glycoprotein promotes both cell attachment and neurite outgrowth. Separate domains on laminin elicit these responses, suggesting that distinct receptors occur on the surface of cells. NG108-15 neuroblastoma-glioma cells rapidly extend long processes in the presence of laminin. We report here that 125I-labeled laminin specifically binds to these cells and to three membrane proteins of 67, 110, and 180 kDa. These proteins were isolated by affinity chromatography on laminin-Sepharose. The 67-kDa protein reacted with antibody to the previously characterized receptor for cell attachment to laminin. Antibodies to the 110-kDa and 180-kDa bands demonstrated that the 110-kDa protein …

Synthesis And Characterization Of N-Alkyl-Adenosine-5'-Diphosphates, Han-Ping Huang

Chemistry & Biochemistry Theses & Dissertations

n-Alkylphosphates and adenosine derivatives have been observed to be competitive inhibitors of coenzyme molecules in many NAD⁺ requiring enzymes. In earlier studies, adenosine derivatives such as AMP, ADP and ADP-ribose were found to be coenzyme competitive inhibitors of the Lactate Dehydrogenase catalyzed reaction. However, n-alkylphosphates, to the contrary, + were found to be noncompetitive inhibitors of NAD⁺.

Furthermore, it was observed previously in Dr. Yuan's laboratory that the effect of n-octylphosphate on the LDH catalyzed reaction was changed from noncompetitive to competitive in the presence of low concentration of AMP. Rossmann et al. reported that the binding …

Variant Forms Of Ataxia Telangiectasia, A. M. R. Taylor, E. Flude, B. Laher, Michael W. Stacey, E. Mckay, J. Watt, S. H. Greens, A. E. Harding

Bioelectrics Publications

Two ataxia telangiectasia patients with unusual clinical and cellular features are described. Cultured fibroblasts and PHA stimulated lymphocytes from these two patients showed a smaller increase of radiosensitivity than cells from other A-T patients, as measured by colony forming ability or induced chromosome damage respectively, after exposure to ionising radiation. The response of DNA synthesis to irradiation of these cells was, however, the same as for other A-T patients. Cells from a third patient with some clinical features of A-T but with a very protracted course also showed low levels of radiation induced chromosome damage, but colony forming ability and …

The Spherical Vision, Nancy Topping Bazin

English Faculty Publications

Virginia Woolf's experiences as a manic-depressive influenced her vision of reality and, in tum, her aesthetics. Manic-depression is a "cyclic" illness-cyclic in the sense that the manic-depressive moves alternately between two extreme psychological states. Hence, he experiences reality in terms of two opposite perspectives. Psychotic depression involves what Jung describes as the experience of the "shadow." That is, looking into the unconscious, the individual sees his own reflection. He takes a risk in looking, for as Jung says, "The mirror does not flatter, it faithfully shows whatever looks into it; namely, the face we never show to the world because …

The Synthesis And Evaluation Of The Cardiovascular Activity Of Novel Imidazole Ring Systems, Joseph E. De Los Angeles

Chemistry & Biochemistry Theses & Dissertations

An investigation was undertaken to synthesize and evaluate the cardiovascular activity of two imidazole ring systems. Imidazoles with hypotensive activity would provide novel potential antihypertensive drugs. These novel structures may also find use as chemical probes in the study of the cardiovascular system and as prototypes for other potential cardiovascular agents.

The histamine derivative, 7,7-dipyridyl-4,5,6,7-tetrahydroimidazo-[4,5-c]pyridine (ligand l), was demonstrated to possess significant hypotensive activity in laboratory rats. A 15 mg/Kg dose of ligand 1 produces a statistically significant decrease in blood pressure when injected IP. This hypotensive effect is also associated with marked increase in heart rate. Although compound 1 …
