| effects of hypercortisolemia and diabetes on skeletal muscle insulin receptor function in vitro and in vivo. | activation of skeletal muscle insulin receptor tyrosine kinase in vitro and in vivo was studied in two rat models of insulin resistance: insulinopenic diabetes and hypercortisolemia. in control rats, intravenous insulin administration resulted in dose-dependent in vivo activation of the muscle insulin receptor kinase towards histone h2b. half-maximal and maximal activation were observed 5 min after injecting 0.1 and 0.5 u insulin/100 g, respectively. diabetes (7 days) induced with streptozotocin ... | 1989 | 2643342 |
| cardiopulmonary baroreflex control of brachial artery diameter in sustained essential hypertension. | an exaggerated reflex response of forearm resistance vessels following stimulation of cardiac mechanoreceptors has been observed in human hypertension. in the present study we analyze the possibility that such an increased response also involves the large brachial artery. for that purpose, the influence of leg elevation in subjects in a supine position on brachial artery diameter and blood flow velocity was studied in 12 healthy, normal males and 17 males of the same age with sustained essential ... | 1989 | 2607141 |
| purification and some properties of a novel l-2,4-diaminobutyric acid decarboxylase from vibrio alginolyticus. | previous investigations have shown that members of the genus vibrio possess a novel enzyme activity decarboxylating l-2,4-diaminobutyric acid (daba) to 1,3-diaminopropane (dap). in this paper we describe the purification, by about 3600-fold, of the enzyme from v. alginolyticus. the purified enzyme was apparently homogeneous, and had a specific activity of 4200 nmol dap min-1 (mg protein)-1. the enzyme protein has an mr of 450,000 +/- 20,000 and is apparently comprised of four identical subunits ... | 1989 | 2614383 |
| inadequate blockade by hexamethonium of the baroreceptor heart rate response in anesthetized and conscious rats. | the ability of hexamethonium (hex) alone or in combination with atropine methylbromide (amb) to block the heart rate (hr) response to baroreceptor activation by phenylephrine (pe) or angiotensin ii (aii)-evoked increments in blood pressure was evaluated in rats. a highly significant negative correlation existed under control conditions between the changes in map and hr. hex (10-20 mg/kg) did not influence the baroreceptor hr response of anesthetized and conscious rats, suggesting anesthesia was ... | 1989 | 2567154 |
| the f1-atpase of vibrio alginolyticus. purification and n-terminal sequence of major subunits. | the f1-type atpase has been isolated from membrane preparations of marine alkalotolerant bacterium, vibrio alginolyticus. the enzyme was found to consist of two major subunits of 55 and 58 kda and at least two minor components (38 and 23 kda). amino acid sequences of n-terminal regions of the major subunits revealed close homology with those of e. coli h+-atpase and of propionigenium modestum na+-atpase. | 1989 | 2532151 |
| use of synthetic ribosome binding site for overproduction of the 5b protein of insertion sequence is5. | insertion sequence is5 is a bacterial transposable element which contains three open reading frames designated 5a, 5b and 5c. although there was no detectable expression from the 5b open reading frame when it was preceded by the native promoter and ribosome binding site or by a tac promoter and the native ribosome binding site, we have overproduced a 5b protein both in vitro and in escherichia coli cells by using a tac promoter and a specially-designed synthetic ribosome binding site. beta-galac ... | 1989 | 2538799 |
| nucleotide sequence and analysis of the vibrio alginolyticus sucrase gene (scrb). | the nucleotide sequence of a 2.119-kb dna fragment containing the vibrio alginolyticus sucrase gene (scrb) was determined. the complete sequence (484 aa residues) of the sucrase was deduced and homology was detected between the sucrase enzymes from v. alginolyticus and the gram-positive bacteria bacillus subtilis and streptococcus mutans. in escherichia coli cells the cloned v. alginolyticus sucrase is translocated to the periplasm. transposon phoa mutagenesis experiments strongly suggested that ... | 1989 | 2551785 |
| concept of the existence of human papillomavirus (hpv) dna in histologically normal squamous epithelium of the genital tract should be re-evaluated. | because of the crucial importance of guiding current thinking in the field of hpv epidemiology, the concept of the existence of hpv dna in histologically normal squamous epithelium was re-evaluated. a series of 102 randomly collected cervical punch biopsies, previously proved to contain the dna of hpv types 6, 11, 16, 18, 31 or 33 by in situ hybridization were subjected to analysis for the localization of hpv dna, i.e., whether found in the normal epithelium or at the lesion site only. this mate ... | 1989 | 2561041 |
| effect of a phospho-oligosaccharidic putative insulin messenger on insulin release in rats. | the phospho-oligosaccharide extracted from rat liver and supposed to act as the insulin second messenger inhibits glucose-stimulated insulin release. in the present study, this phospho-oligosaccharide was found not to affect d-[u-14c]glucose oxidation and 45ca net uptake, but to inhibit insulin release evoked by either d-glucose or 2-ketoisocaproate in isolated rat islets. the relative extent of the latter inhibition was unaffected by either the concentration of d-glucose or the presence of dibu ... | 1989 | 2666215 |

| enzyme polymorphism and clinical variability of diseases: a study of diabetes mellitus. | we investigated possible relations among four common neonatal manifestations of diabetic pregnancy (macrosomia, hypoglycemia, hypocalcemia, jaundice) and four enzyme polymorphisms (pgm1, ada, ak1, acp1 in a sample of infants born of diabetic mothers. the pattern of associations observed between the two sets of variables is consistent with known differences in enzymatic activity within phenotypes of each system, suggesting that low enzymatic activity may have unfavorable effects on fetal developm ... | 1989 | 2556341 |
| the sodium cycle: a novel type of bacterial energetics. | the progress of bioenergetic studies on the role of na+ in bacteria is reviewed. experiments performed over the past decade on several bacterial species of quite different taxonomic positions show that na+ can, under certain conditions, substitute for h+ as the coupling ion. various primary na+ pumps (delta mu na+ generators) are described, i.e., na+ -motive decarboxylases, nadh-quinone reductase, terminal oxidase, and atpase. the delta mu na+ formed is shown to be consumed by na+ driven atp-syn ... | 1989 | 2687258 |
| sodium-transport nadh-quinone reductase of a marine vibrio alginolyticus. | the respiratory chain of a marine bacterium, vibrio alginolyticus, required na+ for maximum activity, and the site of na+ -dependent activation was localized on the nadh-quinone reductase segment. the na+ -dependent nadh-quinone reductase extruded na+ as a direct result of redox reaction. it was composed of three subunits, alpha, beta, and gamma, with apparent mr of 52, 46, and 32 kda, respectively. the reduction of ubiquinone-1 to ubiquinol proceeded via ubisemiquinone radicals. the former reac ... | 1989 | 2687259 |
| a study on na+ -coupled oxidative phosphorylation: atp formation supported by artificially imposed delta pna and delta pk in vibrio alginolyticus cells. | addition of na+ to the k+-loaded vibrio alginolyticus cells, creating a 250-fold na+ gradient, is shown to induce a transient increase in the intracellular atp concentration, which is abolished by the na+/h+ antiporter, monensin. the delta pna-supported atp synthesis requires an additional driving force supplied by endogenous respiration or, alternatively, by a k+ gradient (high [k+] inside). in the former case, atp formation is resistant to the protonophorous uncoupler. dicyclohexylcarbodiimide ... | 1989 | 2473063 |
| evolution of antioxidant mechanisms: thiol-dependent peroxidases and thioltransferase among procaryotes. | glutathione peroxidase and glutathione s-transferase both utilize glutathione (gsh) to destroy organic hydroperoxides, and these enzymes are thought to serve an antioxidant function in mammalian cells by catalyzing the destruction of lipid hydroperoxides. only two groups of procaryotes, the purple bacteria and the cyanobacteria, produce gsh, and we show in the present work that representatives from these two groups (escherichia coli, beneckea alginolytica, rhodospirillum rubrum, chromatium vinos ... | 1989 | 2515292 |
| biochemical and antigenic characterization of cd45 polypeptides expressed on plasma membrane and internal granules of human neutrophils. | the expression of cd45 polypeptides, a phosphotyrosine phosphatase complex specific of leukocytes, has been investigated in both resting and activated neutrophils by using anti-cd45 monoclonal antibodies (mab) which specifically recognize different polypeptide components of the cd45 molecular complex. polypeptides of 180 and 130-150 kda were equally precipitated by either a conventional cd45 mab recognizing an antigenic determinant shared by the four cd45 glycoproteins (220, 205, 190 and 180 kda ... | 1989 | 2525488 |

| a primary respiratory na+ pump of an anaerobic bacterium: the na+-dependent nadh:quinone oxidoreductase of klebsiella pneumoniae. | membranes of klebsiella pneumoniae, grown anaerobically on citrate, contain a nadh oxidase activity that is activated specifically by na+ or li+ ions and effectively inhibited by 2-heptyl-4-hydroxyquinoline-n-oxide (hqno). cytochromes b and d were present in the membranes, and the steady state reduction level of cytochrome b increased on nacl addition. inverted bacterial membrane vesicles accumulated na+ ions upon nadh oxidation. na+ uptake was completely inhibited by monensin and by hqno and sl ... | 1989 | 2545175 |
| differential effects of the destruction of leydig cells by administration of ethane dimethane sulphonate to postnatal rats. | ethane dimethane sulphonate (eds) is a cytotoxic drug that selectively destroys leydig cells in adult testes. this study has examined the effect of a single injection of eds on the leydig cell populations present in the testes of rats aged 5, 10, or 20 days. microscopic examination of the tissue demonstrated that the fetal leydig cell population was destroyed at all ages, but that subsequent development of the adult population of leydig cells was not affected. whilst the destruction of the fetal ... | 1989 | 2546615 |
| nucleotide sequence of the vibrio alginolyticus calcium-dependent, detergent-resistant alkaline serine exoprotease a. | the nucleotide sequence of the vibrio alginolyticus alkaline serine exoprotease a (proa) gene cloned in escherichia coli was determined. the exoprotease a gene (proa) consisted of 1602 bp which encoded a protein of 534 amino acids (aa) with an mr of 55,900. the region upstream from the gene was characterized by a putative promoter consensus region (-10 -35), a ribosome-binding site and atg start codon. the proa gene encodes a typical 21-aa n-terminal signal sequence which, when fused to alkaline ... | 1989 | 2546861 |
| hydrogen peroxide mutagenicity towards salmonella typhimurium. | in bioassays conducted under controlled, comparable conditions, weak direct mutagenicity responses were observed for hydrogen peroxide in the standard (ames test) agar plate incorporation bioassay with salmonella typhimurium strains ta97, ta98, ta102, and ta1537, in a 20 min preincubation test with strains ta97, ta98, ta100, ta102, ta1537, and ta1538, and in a liquid incubation modification using strain ta1537. these results conclusively demonstrate that hydrogen peroxide is a weak mutagen, espe ... | 1989 | 2572065 |
| [the detection of vibrio parahaemolyticus and vibrio alginolyticus using modified culture media]. | studies have been completed for the detection of vibrio(v.) parahaemolyticus and v. alginolyticus in baltic sea fish. the author had prepared for that purpose a liquid culturing medium and a solid substrate. the percentage of positive findings is remarkable. the results so far recorded should be a good reason for further studies. | 1989 | 2619483 |
| renal metabolism of the oxidized form of ascorbic acid (dehydro-l-ascorbic acid). | we evaluated whether specific transport and metabolic properties exist in rat and guinea pig kidney for handling the immediate oxidative product of ascorbic acid, dehydro-l-ascorbic acid. isolated tubules were used to measure uptake of 10 microm [14c]-dehydro-l-ascorbic acid over an 8-min incubation period. uptake did not show dependence on the bathing media electrolyte composition but was inhibited to some extent by glucose. in tubules of both animal species the majority of 14c label present in ... | 1989 | 2912166 |
| mechanism of lhrh-stimulated steroidogenesis in rat leydig cells: lipoxygenase products of arachidonic acid may not be involved. | luteinizing hormone releasing hormone agonist, [(imbzl)-dhis6,pro9,net]-lhrh (lhrh-a), caused a two to threefold increase in in vitro testosterone (t) secretion by rat leydig cells. this lhrh-a-induced t secretion was completely blocked by quinacrine and chloroquine, inhibitors of phospholipase a2. addition of phospholipase a2, however, was ineffective in stimulating basal or lhrh-a-induced t secretion. phospholipase c, on the other hand, significantly stimulated both basal and lhrh-a-induced t ... | 1989 | 2695506 |
| [existence of an additional structural component in the basal bodies of escherichia coli and vibrio alginolyticus flagellae]. | the structure of escherichia coli and vibrio alginolyticus flagella was studied using electron microscopy. an additional protein structure was shown to exist in the basal bodies of intact flagella in these organisms. it is possible that this structure involves three proteins important for the assembly of flagella, energy transduction, and a change-over in the direction of flagellar rotation. | 1989 | 2695799 |
| quantitative analysis of labelled inner retinal proteins in experimental optic neuritis. | in order to determine if axonal transport changes in chronic experimental allergic encephalomyelitis (eae) were due to blockade or increased discharge of fast transported proteins from the inner retina, we examined the presence of pulse labeled proteins in autoradiograms of the optic nerve head, retinal ganglion cell and nerve fiber layers of juvenile strain-13 guinea pigs with chronic eae and normal controls. quantitative analysis of silver grains, performed six and twenty-four hours following ... | 1989 | 2707041 |

| interactions between different strains of vibrio alginolyticus and hemolymph fractions from adult mytilus edulis. | the juvenile-bivalve pathogen vibrio alginolyticus ncmb 1339 was toxic, in vitro, to hemocytes from adult mytilus edulis. toxicity was mediated by both washed bacterial cells and culture supernates. washed cells of an environmental isolate of v. alginolyticus, strain ps-1, were 2.5 times less toxic to mytilus hemocytes, but this strain did produce a lethal extracellular factor(s) in broth culture, albeit at lower levels than v. alginolyticus ncmb 1339. hemolymph fractions from mytilus exerted a ... | 1990 | 2376663 |
| generation of affinity for antithrombin iii by supplemental sulfation of heparin species with low affinity for the protein. | the tributylammonium salt of a porcine heparin subfraction with low affinity for antithrombin iii (mr 7,500-18,000; anti-clotting activity, 7 usp units/mg), having degrees of sulfate substitution at d-glucosamine and l-iduronic acid residues of glcns 0.786, glcn6s 0.628, and idoa2s 0.682 mol, was reacted with 10 or 20 mol of pyridine-sulfur trioxide per mol equiv. of available hydroxyl groups in n,n-dimethylformamide at -10 degrees c for 1 h. both chemical and nmr spectroscopic analyses revealed ... | 1990 | 2292586 |
| mechanisms of sodium transport in bacteria. | in some bacteria, an na+ circuit is an important link between exergonic and endergonic membrane reactions. the physiological importance of na+ ion cycling is described in detail for three different bacteria. klebsiella pneumoniae fermenting citrate pumps na+ outwards by oxaloacetate decarboxylase and uses the na+ ion gradient thus established for citrate uptake. another possible function of the na+ gradient may be to drive the endergonic reduction of nad+ with ubiquinol as electron donor. in vib ... | 1990 | 1970650 |
| effects of respiratory activity on starvation survival of marine vibrios. | the marine bacterium vibrio fluvialis nctc11328 responded to nutrient depletion by a reduction in cell volume, and this was prevented by conditions that eliminated respiration as a source of energy. addition of the protonophore, cccp, removal of oxygen and introduction of mutations leading to defects of the respiratory chain prevented size reduction during periods of nutrient limitation. further, survival of the wild-type strain during starvation was reduced under anaerobic conditions and surviv ... | 1990 | 2154166 |
| polyamine metabolism and uptake during phaseolus vulgaris lectin, pha-induced growth of rat small intestine. | kidney bean lectin, pha, stimulated the hyperplastic and hypertrophic growth of rat small intestine. this growth was preceded by a rapid accumulation of polyamines in the small intestine. however, since the lectin had little effect on in situ polyamine biosynthesis, most of the polyamines must have been of extracellular origin. to investigate the source of polyamines, both the luminal uptake and basolateral transport of polyamines by the rat small intestine were measured in vivo. luminal polyami ... | 1990 | 2262068 |
