heterogeneity of fast-oxidative muscle fibers of chicken demonstrated by anti-myosin monoclonal antibodies.	the fiber type composition of two fast muscles of the chicken, namely, adductor superficialis (as) and pectoralis major (pm) was examined by the histochemical myosin atpase staining and immunochemical techniques using monoclonal antibodies (mcabs). two new mcabs produced against the myosin of the anterior latissimus dorsi (ald) muscle of the chicken and named ald-122 and ald-83 were characterized to be specific for myosin heavy chain (mhc) and for myosin light chain-1 respectively. they were use ...	1989	2737924
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
evidence of functional alpha 2-adrenergic receptors in adult-rat adipocytes by using the agonist uk 14304.	the aim of this study was to re-assess whether alpha 2-adrenergic receptors were present in rat adipocytes, by using uk 14304, a new and very selective alpha 2-agonist. the following observations demonstrate the presence of functional alpha 2-adrenoceptors in rat adipocytes. (1) adipocyte lipolysis was dose-dependently inhibited by uk 14304 (maximal effect 80% at 1 microm-uk 14304, 45% at 10 microm-uk 14304, under basal or theophylline-stimulated conditions respectively). (2) uk 14304 bound spec ...	1988	2901830
studies on the factors affecting the haemolysin production of vibrio mimicus isolated from clinical and environmental sources.	the in vitro production of haemolysin by vibrio mimicus, a newly described aetiological agent for human diarrhoea, was determined using sheep erythrocytes. the effects of medium composition and sodium chloride concentration on haemolysin production and its heat stability were investigated. the haemolysin was produced optimally in brain-heart infusion broth and was unaffected by salt concentration up to 1.5%. however, haemolysin production decreased gradually with increasing concentrations of sal ...	1988	3188168
structural and functional studies of the effects of sympathetic nerve stimulation on rabbit submandibular salivary glands.	continuous sympathetic stimulation at 8-10 hz caused intense vasoconstriction in the gland, so stimulation was generally given in an interrupted pattern to minimize this detrimental effect on secretion. only a small increase in fluid secretion occurred; it became thick and tended to block the cannula; therefore in later experiments the main duct was not cannulated. after sympathetic stimulation there was substantial degranulation of acinar cells. however, as this was accompanied by little moveme ...	1988	3165262
simultaneous measurement of preferred ambient temperature and metabolism in rats.	a recent study from this laboratory found that rats placed in a temperature gradient preferred ambient temperatures (ta) that were significantly below the lower critical ta of the thermoneutral zone for elevating metabolic rate (mr). to further evaluate the interaction between preferred ta and mr in the rat, a system was developed where preferred ta, mr (i.e., o2 consumption), and activity could be automatically monitored in the unrestrained rat. two groups of male sprague-dawley rats, a light-w ...	1988	3344833
coagglutination of vibrio cholerae, vibrio mimicus, and vibrio vulnificus with anti-flagellar monoclonal antibody.	monoclonal antibodies (mabs) with serological activity for purified flagellar (h) core protein prepared from vibrio cholerae were identified by enzyme-linked immunosorbent assay. four of these mabs reacted with the flagella of v. cholerae and v. mimicus exclusively, while eight mabs reacted with at least 1 of 30 heterologous vibrio species tested by enzyme-linked immunosorbent assay or coagglutination. it appears that v. cholerae and v. mimicus express similar, if not identical, h determinants u ...	1988	3182988
excision of cutaneous tumors in the horse using histologic guidance.	a highly successful surgical technique for removing cutaneous tumors in humans was used in seven horses with cutaneous squamous cell carcinoma (n = 3) or sarcoid (n = 4). in humans, the complete underside of the tumor is evaluated histologically by processing horizontal sections from the tumor base, and orientation between the wound surface and the undersurface of the excised tumor is maintained by mapping both surfaces. the technique ensures that small foci of residual tumor can be located accu ...	1988	3227634
hypergammaglobulinemia associated with human immunodeficiency virus infection.	the serum concentrations of 11 ig isotypes (igg, igg1, igg2, igg3, igg4, iga, iga1, iga2, igm, igd, and ige) were measured in four relatively small groups of homosexual (or bisexual) males. all these patients were seropositive for hiv. two of the groups (nonprogressors) were clinically stable for approximately 2 years and were characterized either as asymptomatic or with pgl. the third group (progressors) developed aids 2-38 months after blood specimens were taken. the fourth group had aids. a f ...	1988	3260340
biosynthesis and processing of platelet gpiib-iiia in human megakaryocytes.	platelet membrane glycoprotein iib-iiia forms a calcium-dependent heterodimer and constitutes the fibrinogen receptor on stimulated platelets. gpiib is a two-chain protein containing disulfide-linked alpha and beta subunits. gpiiia is a single chain protein. these proteins are synthesized in the bone marrow by megakaryocytes, but the study of their synthesis has been hampered by the difficulty in obtaining enriched population of megakaryocytes in large numbers. to examine the biosynthesis and pr ...	1987	3108266
structural and functional studies of the amino terminus of yeast metallothionein.	purified yeast copper-metallothionein lacks 8 amino-terminal residues that are predicted from the dna sequence of its gene. the removed sequence is unusual for metallothionein in its high content of hydrophobic and aromatic residues and its similarity to mitochondrial leader sequences. to study the significance of this amino-terminal cleavage, several mutations were introduced into the metallothionein coding gene, cup1. one mutant, which deletes amino acid residues 2-8, had a minor effect on the ...	1987	3308865
trimethoprim used for selective decontamination of the digestive tract in rats: possible route of excretion.	selective elimination of enterobacteriaceae species from the digestive tract of rats has been accomplished by oral treatment with trimethoprim (235 mg/kg body weight/day) within 6 days. in the present study it was investigated whether this elimination was mainly due to antimicrobial activity of trimethoprim excreted with the gastrointestinal mucus or mainly by non-absorbed trimethoprim in the lumen contents. by means of whole gut irrigation (wgi) the lumen contents were washed out, followed by m ...	1987	3497436
