| 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 |
| 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 |
| reflections on tissue characterisation. | theoretical predictions that absorption and velocity dispersion, in addition to characteristic acoustic impedance mismatch, mediate the reflectivity of a planar interface are explored. a technique to measure the frequency dependence of the reflectivity is described: a special hydrophone, purpose-built to this end, is utilised in order to show that perspex/water and neoprene/water reflectivities are not inconsistent with the general predictions of the theory. an approach towards displaying, simul ... | 2008 | 2587629 |
| mental ability, symbolic play and receptive and expressive language of young children with down's syndrome. | the relationship between measures of mental ability, symbolic play and expressive and receptive language was investigated in a sample of 73 children with down's syndrome (mean ca 48.9 months, range 19-90 months; mean ma 30.4 months, range 13-73 months). language delay became increasingly apparent with age, and more so in boys than girls. there was no significant difference between mental ages derived from standard ability tests and corresponding age equivalent scores of the lowe and costello sym ... | 2008 | 2579964 |
| generation of the electrochemical potential of na+ by the na+-motive nadh oxidase in inverted membrane vesicles of vibrio alginolyticus. | inverted membrane vesicles prepared from vibrio alginolyticus generated a membrane potential (positive inside) and accumulated na+ by the oxidation of nadh. generation of the membrane potential required na+ and was inhibited by 2-heptyl-4-hydroxyquinoline n-oxide, a specific inhibitor of the na+-dependent nadh oxidase. collapse of the membrane potential by valinomycin stimulated the uptake of na+. in contrast, accumulation of h+ was not detected under all the conditions tested. these results sug ... | 1985 | 2579856 |
| [determination of antibodies to streptococcus group a polysaccharide in human sera by an immunoenzyme method]. | use was made of the elisa to develop a highly sensitive quantitative method for detection of antibodies against streptococcus group a polysaccharide (polysaccharide a) in human sera. the main advantage is that one can use only one optimal dilution of the sera together with the reference serum. sera of 53 healthy volunteers and 77 patients with a history of streptococcus group a infections were screened for the presence of polysaccharide a antibodies. highly reproducible results were obtained in ... | 1985 | 2578835 |
| nucleotide sequence of the vibrio alginolyticus glna region. | the nucleotide sequence of a 4 kb fragment containing the vibrio alginolyticus glna, ntrb and ntrc genes was determined. the upstream region of the glna gene contained tandem promoters. the upstream promoter resembled the consensus sequence for escherichia coli sigma 70 promoters whereas the presumptive downstream promoter showed homology with nitrogen regulated promoters. four putative nri binding sites were located between the tandem promoters. the ntrb gene was preceded by a single presumptiv ... | 1989 | 2574025 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |

| 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 |
| comparison of substance k-like and substance p-like fibers and cells in the rat hippocampus. | substance p (sp) and substance k (sk) are structurally related peptides which are both encoded in the preprotachykinin a gene. the distribution of sp- and sk-like fibers and cell bodies in the rat hippocampus were studied by immunohistochemistry. the distribution of sk-like fibers was similar to that of sp-like fibers but there were few sk-like fibers. fibers for both peptides were prominent in the dorsal and ventral subiculum and at the junction of ca2 and ca3. sp- and sk-like cell bodies were ... | 1987 | 2446709 |
| evolution and development of the outer acrosomal membrane (oam) and evidence that acrosin-inhibitors are proteins of the oam. | an antiserum to the purified porcine outer acrosomal membrane (oam) was raised in rabbits and the igg fraction isolated by ammonium sulphate precipitation and ion exchange chromatography. the antibodies reacted exclusively with the acrosomal cap of the sperm head as revealed by indirect immunofluorescence. in addition they cross-reacted not only with the acrosomal part of the spermatozoa of all mammalian species tested (bull, horse, rabbit, rat, mouse, hamster, mole, antelope, monkey, man) but a ... | 1987 | 2446533 |
| cystic neoplasms of the pancreas. | eight patients with cystic neoplasms of the pancreas were seen at four northern california hospitals between the years 1978 and 1986. three of the tumors were benign and five were malignant. three females, whose average age was 61 years, had cystadenomas. three females and two males, whose average age was 48 years, had mucinous cystadenocarcinomas. clinical presentations were similar among all patients. abdominal pain was a prominent feature. anorexia, weight loss, nausea and vomiting with a pal ... | 2008 | 2446398 |
| [similarity of vibrio alginolyticus, v. cholerae and other vibrio species with respect to the structure of their flagellar apparatus and ribosomal 5s-rna]. | electron microscopic analysis of basal bodies of the flagella vibrio alginolyticus revealed a structure composed of four discs. the diameters of two discs localized in the cytoplasmic membrane appeared to be twice as little as those of the other two discs. in this respect the basal body of v. alginolyticus resembles that of v. cholerae. the 5s sequence of ribosomal rna from v. alginolyticus appeared to be similar to those of v. cholerae, v. harveyi and some other vibrios. comparison of 5s-rna se ... | 1987 | 2434145 |
| the sodium cycle. i. na+-dependent motility and modes of membrane energization in the marine alkalotolerant vibrio alginolyticus. | respiration, membrane potential generation and motility of the marine alkalotolerant vibrio alginolyticus were studied. subbacterial vesicles competent in nadh oxidation and delta psi generation were obtained. the rate of nadh oxidation by the vesicles was stimulated by na+ in a fashion specifically sensitive to submicromolar hqno (2-heptyl-4-hydroxyquinoline n-oxide) concentrations. the same amounts of hqno completely suppressed the delta psi generation. delta psi was also inhibited by cyanide, ... | 1986 | 2425848 |
| vascular myogenic or stretch-dependent tone. | myogenic tone is an important source of vascular resistance, which appears to depend upon stretch of the vessel wall. it contributes to autoregulation, is dependent upon external calcium, and may involve a calcium-entry mechanism different from that associated with the action of agonists and changes in the membrane potential. | 2008 | 2409386 |
| antimelanoma monoclonal antibody-ricin a chain immunoconjugate (xmmme-001-rta) plus cyclophosphamide in the treatment of metastatic malignant melanoma: results of a phase ii trial. | prior studies with the xmmme-001-rta immunoconjugate composed of an antimelanoma monoclonal antibody and ricin a chain demonstrated some antitumor activity. however, almost all patients studied developed human antimurine antibodies and antiricin antibodies. in an effort to abrogate these host anti-immunotoxin immune responses and thus enhance antitumor activity, we treated 20 patients with the immunoconjugate plus a single dose of intravenous cyclophosphamide. an overall response rate of 20% was ... | 1990 | 2395000 |
| ion selectivity of the vibrio alginolyticus flagellar motor. | the marine bacterium, vibrio alginolyticus, normally requires sodium for motility. we found that lithium will substitute for sodium. in neutral ph buffers, the membrane potential and swimming speed of glycolyzing bacteria reached maximal values as sodium or lithium concentration was increased. while the maximal potentials obtained in the two cations were comparable, the maximal swimming speed was substantially lower in lithium. over a wide range of sodium concentration, the bacteria maintained a ... | 1990 | 2394685 |
| 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 |
| number and types of hemocytes in sunetta scripta and villorita cyprinoides var. cochinensis (bivalvia), and leukocytosis subsequent to bacterial challenge. | the number and types of hemocytes in four size groups of the clam species sunetta scripta and villorita cyprinoides var. cochinensis, and leukocytosis in the 38- to 40-mm-size-group clams of both species subsequent to challenge with vibrio alginolyticus at a concentration of 1 x 10(8) cells/0.02 ml of sterile 2% saline was investigated. in s. scripta, the mean total hemocyte count in the 42- to 44-mm size group was significantly lower than that of the three other size groups but there was no sig ... | 1990 | 2351842 |
| improved fluorogenic assay for rapid detection of vibrio parahaemolyticus in foods. | an improved fluorogenic assay for the rapid detection of vibrio parahaemolyticus was developed. in the improved assay, the enrichment of v. parahaemolyticus was carried out in arabinose-glucuronate medium (0.5% arabinose, 0.25% glucuronate, 0.1% polypeptone, 0.1% yeast extract, 0.1% ammonium sulfate, 2% nacl, 2 micrograms of polymyxin b sulfate per ml, ph 8.5) at 37 degrees c. after the cultivation, the trypsinlike activity of the bacteria was measured by fluorescence with the fluorogenic substr ... | 1990 | 2339897 |
| copper-induced production of copper-binding supernatant proteins by the marine bacterium vibrio alginolyticus. | growth of the marine bacterium vibrio alginolyticus is temporarily inhibited by micromolar levels of copper. during the copper-induced lag phase, supernatant compounds which complex and detoxify copper are produced. in this study two copper-inducible supernatant proteins having molecular masses of ca. 21 and 19 kilodaltons (cubp1 and cubp2) were identified; these proteins were, respectively, 25 and 46 times amplified in supernatants of copper-challenged cultures compared with controls. experimen ... | 1990 | 2339887 |
