| clostridial infection of renal cell carcinoma. | we report a case of a large gas-filled clostridial abscess in a previously unrecognized renal cell carcinoma. neoplastic tissue has a nonhomogeneous blood supply, creating areas of hypoxia and reduced glucose concentrations, which lead to tumor necrosis and an environment conducive to the growth of anaerobic organisms. anaerobic infection should be considered in any patient with carcinoma and fever. conversely, abscess transformation of a tumor can be the explanation for what otherwise seems to ... | 1986 | 2868130 |
| studies on neurotransmitter markers and neuronal cell density in the cerebellar system in olivopontocerebellar atrophy and cortical cerebellar atrophy. | glutamate, aspartate and gamma-aminobutyrate (gaba) concentrations and choline acetyltransferase (chat) activity were measured in postmortem cerebellar cortical areas and brainstem nuclei of 10 normal controls, 5 patients of olivopontocerebellar atrophy (opca) with multiple system atrophy (msa) and 2 patients of cortical cerebellar atrophy (cca). in addition, the neuronal cell density in the cerebellar cortex and the brainstem nuclei was determined, and the correlation between neurotransmitter m ... | 2010 | 2868072 |
| involvement of gangliosides in rabies virus infection. | the role of gangliosides in rabies virus infection of chick embryo-related (cer) cells was investigated. cultured cells were pretreated with neuraminidase to render the cells transiently non-susceptible to viral infection. incubation of these desialylated cells with gangliosides allowed them to incorporate exogenous gangliosides and they recovered their susceptibility to rabies virus infection. infection of cer cells was monitored by specific fluorescence 24 h after virus inoculation. the use of ... | 1986 | 2868068 |
| expert system for pharmaceutical analysis. i. selection of the detection system in high-performance liquid chromatographic analysis: uv versus amperometric detection. | the usefulness of amperometric detection in pharmaceutical analyses was investigated for different groups of drugs. the uv response at 254 nm and that at the absorption maximum of the solute were compared with the electrochemical signal obtained. the minimum detectable concentration (nanograms on-column) of each substance is reported for the three different detection systems. this comparison was performed for 72 drugs (local anaesthetics, antipyretics, tricyclic antidepressants, sulphonamides, s ... | 2010 | 2868023 |
| regulation of protein synthesis in heat-shocked drosophila cells. soluble factors control translation in vitro. | we have developed an in vitro translation system from heat-shocked and normal drosophila cultured cells. the lysates retain regulation of translation typical of the whole cells from which they were prepared, both when programmed by endogenous mrna and when rna-dependent. these systems have been used to investigate the mechanism of shutdown of normal protein synthesis and selection of heat shock mrnas for translation in heat shock in drosophila. supplementation of intact rna-dependent lysates wit ... | 2010 | 2868010 |
| action of excitatory amino acids and their antagonists on hippocampal neurons. | intracellular recordings were obtained from guinea pig hippocampal neurons maintained in vitro. current- and voltage-clamp techniques were used to study the effect of microiontophoresis of excitatory amino acid agonists. modification of agonist responses by bath application of known concentrations of antagonist agents was also examined. all agonists used, glutamate, aspartate, n-methyl-d-aspartic acid (nmda), and quisqualate, depolarized hippocampal neurons and caused repetitive firing. nmda was ... | 1985 | 2867826 |
| the effect of mixed-function oxidation of enzymes on their susceptibility to degradation by a nonlysosomal cysteine proteinase. | mixed-function oxidation of escherichia coli glutamine synthetase by ascorbate, oxygen, and iron has previously been shown to cause inactivation of the enzyme and enhanced susceptibility to proteolytic attack by a variety of proteases. one of these proteases, from rat liver, is a high molecular weight cysteine proteinase which does not degrade native glutamine synthetase at neutral ph. although inactive, the oxidized glutamine synthetase preparations used in this study were only partially degrad ... | 1985 | 2867745 |

| lymphatic transport of sodium cefoxitin in the presence of sodium 5-methoxysalicylate after injection into rat rectal connective tissue, femoral muscle and femoral vein. | lymphatic uptake of sodium cefoxitin after injection into rectal connective tissue was greater than after injection into the femoral muscle of rats. coadministration with sodium 5-methoxysalicylate enhanced lymphatic drug uptake at both sites. this enhancement may be an indirect result of 5-methoxysalicylate's suppression of vascular permeation of the cefoxitin. an adjuvant-induced increase in lymphatic fluid flow may also be partially involved in the enhancement of cefoxitin lymphatic transport ... | 1985 | 2863362 |
| protein phosphatases active on acetyl-coa carboxylase phosphorylated by casein kinase i, casein kinase ii and the camp-dependent protein kinase. | the protein phosphatases in rat liver cytosol, active on rat liver acetyl-coa carboxylase (acc) phosphorylated by casein kinase i, casein kinase ii and the camp-dependent protein kinase, have been partially purified by anion-exchange and gel filtration chromatography. the major phosphatase activities against all three substrates copurify through fractionation and appear to be identical to protein phosphatases 2a1 and 2a2. no unique protein phosphatase active on 32p-acc phosphorylated by the case ... | 1985 | 2862868 |

| comparative evaluation of three identification systems for anaerobes. | the accuracy of two new 4-h identification systems for anaerobes, the an-ident (analytab products, plainview, n.y.) and the rapid ana (innovative diagnostic systems, inc., atlanta, ga.) was compared with that of the api 20a system (analytab products). a total of 132 clinical isolates were tested in each of the three systems. the overall accuracies at the genus and species level for the three systems were: api 20a, 68.9 and 56.8%, respectively; an-ident, 90.2 and 73.5%; and rapid ana, 93.9 and 81 ... | 1985 | 2862161 |
| neuraminidase activity is not the cause of influenza virus-induced neutrophil dysfunction. | influenza viruses have been shown to decrease the ability of polymorphonuclear leukocytes (pmn) to respond to a variety of stimuli. this study was done to determine if viral neuraminidase was responsible for decreased pmn function. treatment of human pmn with purified neuraminidases from influenza virus, vibrio cholerae, or clostridium perfringens did not significantly affect the ability of human pmn to respond to stimulation. occasional virus preparations that lacked the ability to depress pmn ... | 1985 | 2862160 |
