| acrylamide neuropathy in a south african factory: an epidemiologic investigation. | acrylamide monomer concentrations and peripheral neurotoxicity were investigated in workers at a factory producing polymer. monomer levels ranged from 0.07 to 2.5 times the recommended exposure limit of the u.s. national institute for occupational safety and health (1988). those workers with exposure exceeding the limit had increased prevalences of acrylamide-related abnormalities. logistic regression showed dose-response relationships with exposure for symptoms, abnormal sensation, decreased mo ... | 2007 | 1852098 |
| differential effects of secretin-fragments imply a dual mechanism of action for secretin. | the effects of synthetic peptides, representing different parts of the secretin molecule in isolated mouse pancreatic islets have been investigated in perifusion studies. in the presence of 10 mm d-glucose the c-terminal nonapeptide leu-gln-arg-leu-leu-gln-gly-leu-val-nh2 (s19-27) showed a 2-fold higher activity than that earlier shown for s22-27 and had the same effect on the dynamic pattern of insulin release as secretin, while the elongating sequence leu-gln-arg (s19-21) had no effect on the ... | 1991 | 1850389 |

| evidence that the asparagine 322 mutant of the lactose permease transports protons and lactose with a normal stoichiometry and accumulates lactose against a concentration gradient. | the single asparagine 322 mutant of the lactose permease was made by constructing a hybrid plasmid which contained the amino-terminal coding sequence from the wild-type permease gene and the carboxyl-terminal coding sequence from a previously characterized double mutant permease which contained an asparagine residue at position 322. since histidine at position 322 has been postulated to be critically involved with h+ transport and the active accumulation of sugars, the ability of the asn-322 mut ... | 1991 | 1849889 |
| vaccines and milk immunoglobulin concentrates for prevention of infectious diarrhea. | considerable progress has been made in the last decade in developing vaccines against the most important enteric infections. two new, widely licensed vaccines (oral ty21a and parenteral vi) are available against typhoid fever, and new attenuated salmonella typhi strains are ready for testing. an engineered live orally administered cholera vaccine, cvd 103-hgr, is undergoing clinical trials for safety, immunogenicity, and transmissibility in children in areas where cholera is endemic. multiple ca ... | 1991 | 1848888 |

| atp-dependent partitioning of the dna template into supercoiled domains by escherichia coli uvrab. | the helicase action of the escherichia coli uvrab complex on a covalently closed circular dna template was monitored using bacterial dna topoisomerase i, which specifically removes negative supercoils. in the presence of e. coli dna topoisomerase i and atp, the uvrab complex gradually introduced positive supercoils into the input relaxed plasmid dna template. positive supercoils were not produced when e. coli dna topoisomerase i was replaced by eukaryotic dna topoisomerase i or when both e. coli ... | 1991 | 1847511 |
| cyclic amp-elevating agents block chemoattractant activation of diradylglycerol generation by inhibiting phospholipase d activation. | agents which elevate cellular camp (prostaglandin e2, theophylline, and forskolin) or mimic camp action (dibutyryl camp) are known to inhibit human neutrophil activation (superoxide generation and secretion) by receptor-linked agonists such as formyl-methionyl-leucyl-phenylalanine (fmlp). herein, we show that these agents also markedly inhibit fmlp-stimulated diradylglycerol generation (assayed by mass methods). the magnitude of inhibition correlated with the ability of a given agent or combinat ... | 1991 | 1847376 |
| absence of na+,k(+)-atpase regulation of endosomal acidification in k562 erythroleukemia cells. analysis via inhibition of transferrin recycling by low temperatures. | transferrin (tf) acidification has been shown to be limited to ph 6 in murine balb/c 3t3 fibroblasts, human a549 epidermoid carcinoma cells, and chinese hamster ovary cells and is followed by alkalinization during recycling. in contrast, tf acidification in the human erythroleukemic cell line k562 proceeds to below ph 5.5, and alkalinization of internal tf during recycling is not observed. to explore the regulation of endosomal ph in k562 cells, we determined whether the existence of an early en ... | 1991 | 1847374 |
| growth arrest induced by transforming growth factor beta 1 is accompanied by protein phosphatase activation in human keratinocytes. | protein phosphorylation and dephosphorylation are involved in regulation of cell growth. we tested the hypothesis that the growth inhibitory effect of transforming growth factor beta 1 (tgf-beta 1) involves activation of protein phosphatases. exposure of human keratinocytes in culture to 400 pm tgf-beta 1 for 48 h led to 80% inhibition of dna synthesis as measured by nuclear labeling. incubation of cultured keratinocytes with 400 pm tgf-beta 1 rapidly activated (within 30 min) protein serine/thr ... | 1991 | 1847373 |
| a series of wide-host-range low-copy-number vectors that allow direct screening for recombinants. | a series of controlled expression vectors was constructed based on the wide-host-range plasmid pmmb66eh. some of these new vectors code for the alpha-peptide of beta-galactosidase and allow the direct screening of recombinant clones by inactivation of alpha-complementation. the bla gene was replaced in some plasmids by the cat gene of tn9 coding for chloramphenicol resistance, extending the use into beta-lactam-resistant strains. they all feature either the tac or taclac (tac-lac uv5 in tandem) ... | 1991 | 1847347 |
| [epidemic of cholera in chile; 1991]. | in january 1991 a severe epidemic of cholera started in peru, a country located north of chile. the first case in chile was confirmed in april and so far 41 cases and 2 deaths have been reported. the epidemic is caused by vibrio cholerae 01, el tor biotype, inaba serotype. most cases occurred in santiago, 2/3 of them in men and all above 15 years of age. an unknown number of asymptomatic infected people arriving in santiago are the likely agents for the epidemic. contamination of sewage and use ... | 1991 | 1844781 |

| hla-dr gene frequencies in the japanese population obtained by oligonucleotide genotyping. | we determined hla-drb types of 375 randomly chosen healthy japanese donors using a set of 29 different sequence-specific oligonucleotide (sso) probes directed against various drb alleles. except for a few cases, these ssos enabled us to identify 33 different drb types including those detectable only by sso genotyping. gene frequencies were calculated for each of the drb types identified. the "blank" frequency calculated by our sso typing was essentially zero, in contrast to the considerably high ... | 2007 | 1839093 |
| growth factors in the regulation of plasminogen-plasmin system in tumor cells. | growth regulatory polypeptides, which act in an autocrine or paracrine fashion, are increasingly implicated in the control of pericellular proteolysis. representatives of major growth factor families, like egf, pdgf, igf, fgf, il, and tgf beta, and in addition, tnfs have effects both on cell proliferation and proteolytic events. some of them participate in the control of proteolytic events by affecting pericellular pa activity. these factors regulate the synthesis, secretion, and activity of bot ... | 2007 | 1839081 |
