the frequency of sister chromatid exchanges following exposure to varying doses of h3-thymidine or x-rays.in the chinese hamster cell line chef-125, sister chromatid exchanges occurred at a rate of a little higher than one per three chromosomes for each cell cycle. the exchanges were detectable by labeling with h(3)-thymidine and autoradiographic analyses of chromosomes at the second and subsequent metaphases after labeling had occurred. to test the hypothesis that sister chromatid exchanges are caused by radiation, cells were incubated in media with different amounts of h(3)-thymidine. no statistic ...196414153478
mammalian chromosomes in vitro. xvii. idiogram of the chinese hamster.from 67 diploid male chinese hamster cells in vitro, an idiogram was constructed. the chromosomes can be classified into 4 natural groups: group i, 2 pairs of large submetacentrics (1 and 2); group ii, 3 pairs of medium-sized submetacentrics (the sex pair, 4 and 5); group iii, 3 pairs of medium-sized subtelocentrics (6,7, and 8); group iv, 3 pairs of small metacentrics (9,10, and 11). a system of subdividing each chromosome into regions is also suggested.196419291904

synergism between halothane and nitrous oxide in the production of nuclear abnormalities in the dividing fibroblast.when chinese hamster fibroblasts divide in the presence of halothane there is an increased incidence of cells with abnormal nuclei, both in mitosis and in interphase. the authors compared the effects of halothane and nitrous oxide separately and in combination. nitrous oxide, 75 percent, alone had no significant effect compared with controls, less than 1.4 per cent of cells showing abnormalities, while halothane alone had a dose-dependent effect on both phases of the cell cycle. halothane, 1 per ...19511275313
etiology of oroya fever : xi. comparison of bartonella bacilliformis and bartonella muris. cultivation of bacterium murium, n. sp.bartonella muris appeared in the blood of all white rats, wild rats, chinese hamster, and mice, from which the spleen was removed, but did not appear in that of splenectomized monkeys, rabbits, or guinea pigs. it has not been possible to transmit b. muris to normal rats, monkeys, rabbits, or guinea pigs, by intraperitoneal, intradermal, or intravenous injection of blood containing b. muris from splenectomized rats. in two instances an acute orchitis was induced in normal rats by injection direct ...192819869409
catalytic residues and a predicted structure of tetrahydrobiopterin-dependent alkylglycerol mono-oxygenase.alkylglycerol mono-oxygenase (ec 1.14.16.5) forms a third, distinct, class among tetrahydrobiopterin-dependent enzymes in addition to aromatic amino acid hydroxylases and nitric oxide synthases. its protein sequence contains the fatty acid hydroxylase motif, a signature indicative of a di-iron centre, which contains eight conserved histidine residues. membrane enzymes containing this motif, including alkylglycerol mono-oxygenase, are especially labile and so far have not been purified to homogen ...022220568
arf6 targets recycling vesicles to the plasma membrane: insights from an ultrastructural investigation.we have shown previously that the adp-ribosylation factor (arf)-6 gtpase localizes to the plasma membrane and intracellular endosomal compartments. expression of arf6 mutants perturbs endosomal trafficking and the morphology of the peripheral membrane system. however, another study on the distribution of arf6 in subcellular fractions of chinese hamster ovary (cho) cells suggested that arf6 did not localize to endosomes labeled after 10 min of horseradish peroxidase (hrp) uptake, but instead was ...09456320
invertebrate specific d1-like dopamine receptor in control of salivary glands in the black-legged tick ixodes scapularis.the control of tick salivary secretion, which plays a crucial role in compromising the host immune system, involves complex neural mechanisms. dopamine is known to be the most potent activator of salivary secretion, as a paracrine/autocrine factor. we describe the invertebrate-specific d1-like dopamine receptor (invd1l), which is highly expressed in tick salivary glands. the invd1l phylogenic clade was found only in invertebrates, suggesting that this receptor was lost in vertebrates during evol ...024307522
mucopolysaccharidosis type i in 21 czech and slovak patients: mutation analysis suggests a functional importance of c-terminus of the idua protein.mucopolysaccharidosis type i (mps i) is an autosomal recessive lysosomal storage disorder that is caused by a deficiency of the enzyme alpha-l-iduronidase (idua). of the 21 czech and slovak patients who have been diagnosed with mps i in the last 30 years, 16 have a severe clinical presentation (hurler syndrome), 2 less severe manifestations (scheie syndrome), and 3 an intermediate severity (hurler/scheie phenotype). mutation analysis was performed in 20 mps i patients and 39 mutant alleles were ...019396826
