mechanism of the epsp synthase catalyzed reaction: evidence for the lack of a covalent carboxyvinyl intermediate in catalysis.	in order to detect covalent reaction intermediates in the 5-enolpyruvylshikimate-3-phosphate (epsp) synthase reaction, we have investigated the interaction of epsp synthase with the reaction product epsp. an exchange of epsp-methylene protons could be demonstrated by incubating epsps with epsp in d2o. since trace amounts of contaminating pi would lead to reversal of epsps reaction and hence methylene proton exchange, we added pyruvate kinase, adp, mg++ and k+. under these conditions, any contami ...	1988	2838023

effect of acute ethanol administration on human blood aldehyde dehydrogenase activity.	the aldehyde dehydrogenase (ec 1.2.1.3) activity in human blood was measured after acute oral administration of two different doses of ethanol to healthy subjects. no changes in aldehyde dehydrogenase activity were observed in either of the two dose groups, as compared to control subjects receiving no ethanol. likewise, incubation of human whole blood samples with 20 mm ethanol for 2 hr caused no change in aldehyde dehydrogenase activity. the results show that human blood aldehyde dehydrogenase ...	1988	3067608
[the body as hostage of the self. phenomenological aspects of anorexia nervosa].	there are several basic structures upon which anorexia nervosa could develop: hostility between mother and daughter, feministic protest, abandonnism, the ascetic structure, the reluctance against the being-thrown-on-the-world, asw. the phenomenological analysis reveals, through these different structures, a common distress. the patient feels the others, and also, the existence, as a violence. yet, she feels help ass in her fight against this violence. so she takes her own body as hostage in orde ...	1988	3207043

glutamate degradation in the ischemic dog heart: contribution to anaerobic energy production.	the present study investigated the conversion of amino acids to succinate and the contribution of this pathway to anaerobic energy production during regional ischemia in the dog heart in situ. the relation between regional myocardial blood flow, estimated by the tracer microsphere technique, and myocardial contents of metabolites (glutamate, alanine, succinate, lactate) as well as their local arterio-venous differences (a-v) were determined. during 30 min of coronary artery occlusion, myocardial ...	1989	2565982
comparative sequence analysis, in vitro expression and biosynthesis of mouse prp.	a number of studies have indicated that an endogenous brain protein, prp, is associated with transmissible agents causing spongiform encephalopathies such as scrapie, kuru, and creutzfeldt-jakob disease. it has been proposed that prp derived from scrapie brain is the scrapie agent itself. to test directly whether the prp mrna in scrapie brain tissue can encode the scrapie agent, we expressed prp cdna cloned from scrapie-infected mouse brain in vitro. the expressed prp did not transmit scrapie to ...	1989	2574873
