d-penicillamine: mitogenic effect on mouse, rat and human spleen lymphocytes.	the effect of d-penicillamine (d-pen) on the proliferation of cultures of normal mouse, rat, and human spleen lymphocytes and peripheral blood lymphocytes was examined. d-pen in concentrations of 2 x 10(-3) m to 8 x 10(-3) m in serum-free and in serum-containing medium resulted in a highly significant incorporation of 3h-tdr by normal mouse and rat spleen cells. enhanced incorporation of 3h-tdr by normal human spleen cells only occurred in serum-containing medium. d-pen in concentrations of 10(- ...	1979	315028
flow cytometry of isolated nuclei prepared from 9l rat brain tumor.	nuclei isolated by grinding 9l rat brain tumors gave a dna distribution consisting of a 2c dna peak due to noncycling normal cells and a bimodal distribution beginning at about 4c dna due to the cycling tumor cells. autoradiographic studies of nuclei from rats that received a pulse of 3h-tdr in vivo confirmed that the majority of proliferating cells were in the bimodal part of the distribution. the fraction of cells in s-phase determined from the dna distributions was 15.3 per cent. this is cons ...	1979	376940
an inducible proline transport system in candida albicans.	1. when candida albicans cells were preincubated with proline or grown in the presence of proline as the sole nitrogen source they exhibited a rapid increase in the influx of proline (the inducible transport system). 2. the induction appeared to be specific for proline and also demonstrated in other candida species. 3. both the inducible and constitutive proline uptake systems exhibited similar characteristic features. 4. the nature of the inducer for proline uptake in c. albicans appeared to be ...	1979	383150
some effects of uncouplers and inhibitors on growth and electron transport in rumen bacteria.	uncouplers and inhibitors of electron transport affected growth and electron transport of rumen bacteria in various ways. selenomonas ruminantium was not affected by inhibitor and uncoupler concentrations which affected growth and electron transport of bacteroides ruminicola, b. succinogenes, and butyrivibrio fibrisolvens. inhibitors, when active, led to accumulation of reduced electron carriers before the site of action, but differences were found among organisms in the site of action of these ...	1979	457609
xylose, arabinose, and rhamnose fermentation by bacteroides ruminicola.	metabolism and growth yields of bacteroides ruminicola grown on d-xylose, l-arabinose, and l-rhamnose were studied. growth yields were 62, 68, and 35.5 g (dry weight) per mol of carbohydrate fermented after correction for storage polysaccharide. experiments with [1-(14)c]arabinose indicated that pentose was fermented by a pentose phosphate cycle plus glycolysis, with some indication of a minor phosphoketolase-type pathway. the product ratios from pentose were similar to those previously describe ...	1979	485153
obligate anaerobes in clinical veterinary practice.	clinical specimens obtained from domestic animals were examined to determine the relative prevalence of obligate anaerobic bacteria and the species represented. of 3,167 samples cultured anaerobically as well as aerobically, 2,234 were bacteriologically positive. of these positive samples, 583 (26%) contained species of obligate anaerobic bacteria in a total of 641 isolates. most positive samples contained anaerobes admixed with aerobic species, although 6% of such samples yielded pure cultures ...	1979	511987

detection of a low-molecular-weight antigen on melanoma cells by a human antiserum in leukocyte-dependent antibody assays.	biochemical characterization of serologically detected human melanoma antigens was undertaken for the development of immunodiagnostic assays in melanoma. an antiserum from a human melanoma patient, which detected melanoma antigens expressed on a large proportion of different melanoma cells, was used in leucocyte-dependent cytotoxic antibody (lda) 51cr-release assays to monitor the purification of melanoma antigens in urea/acetate extracts of lactoperoxidase 125i-labelled melanoma cell membranes. ...	1979	91379
spontaneous interictal spiking in the awake kindled rat.	the spontaneous interictal spike (sis) noted in eeg recordings is a signal of the abnormally excitable behavior of neurons in an epileptic focus. this study provides a detailed, quantitative, temporal and spatial profile of sis in the amygdaloid kindled rat. the reproducible nature of the development and decline of sis in kindling provides a useful model for biochemical study of the mechanisms that initiate and regulate sis.	1979	91486
the specificity of human autoantibodies that react with both cell nuclei and plasma membranes: the nuclear antigen is present on core mononucleosomes.	we have examined the nature of the nuclear antigen recognized by certain natural human antibodies that react specifically with both cell nuclei and plasma membranes from many species. partial purification of these antibodies, called x-ana, is achieved by binding to and rapid elution from the surface of viable human leukocytes. chicken erythrocyte chromatin was solubilized by digestion with staphylococcal nuclease and fractionated into a 0.15 m nacl soluble fraction that consisted of core mononuc ...	1979	91640
