| glomerulopathy in renal allografts from patients with and without active cytomegalovirus infection. | cytomegalovirus (cmv) infection may affect renal graft survival, and a distinctive diffuse glomerulopathy has been described in renal grafts from patients with an active cmv infection. fifty renal graft biopsies taken 30 to 180 days post-transplant from patients with primary, reactivated, inactive and no cmv infection were examined retrospectively for evidence of this glomerulopathy without knowledge of cmv status. the lesion was found in seven of 30 patients with reactivated cmv infection, one ... | 1989 | 2546717 |
| the process of baculovirus deproteinization. | the localization and function of alkaline protease inside the supervirion capsids (granules, inclusion bodies) of granulosis virus and nuclear polyhedrosis virus have been determined with the help of electron microscopy. it has been shown that deproteinization of baculoviruses proceeds in several steps. the first two stages (the release of virus from supervirion capsids and the release of nucleocapsids from the internal and external coats, were accomplished in the intestine of the insects, while ... | 1989 | 2576597 |

| quantitative bacteriology of a case of acute parotitis. | it is generally assumed that the microorganisms responsible for acute suppurative parotitis are facultative anaerobes, primarily staphylococcus aureus and streptococcus viridans. a quantitative microbiologic investigation of an aspirate of pus from the case we report revealed a microbial flora (5.1 x 10(6) cfu/ml) consisting entirely of strict anaerobes (fusobacterium nucleatum and peptostreptococcus anaerobius). the strain of f. nucleatum was sensitive to metronidazole but resistant to penicill ... | 1989 | 2682427 |
| serological studies of peptostreptococci using an indirect fluorescent antibody test. | members of the genus peptostreptococcus are frequent isolates from periodontal lesions. a study was undertaken for determination of the serological relationships of oral and non-oral strains of several species of this genus. eighty-nine strains of peptostreptococci representing seven species were tested by means of an indirect fluorescent antibody technique (ifa), with rabbit antisera to peptostreptococcus anaerobius atcc 27337, peptostreptococcus micros vpi 2618-a, and peptostreptococcus produc ... | 1989 | 2685068 |

| disease response to tobacco mosaic virus in transgenic tobacco plants that constitutively express the pathogenesis-related pr1b gene. | correlation of the temporal and spacial pattern of induction of the pathogenesis-related (pr) genes pr1a, pr1b, and pr1c with viral infections in certain tobacco cultivars has implicated pr proteins in viral disease resistance. to test whether the pr1 proteins of tobacco are involved in viral resistance, transgenic nicotiana tabacum plants were constructed which constitutively express the pr1b gene. this protein was secreted from cells of transgenic plants and accumulated in the extracellular sp ... | 1989 | 2815592 |

| bevantolol hydrochloride--preclinical pharmacologic profile. | bevantolol hydrochloride, a beta adrenoceptor antagonist, can be categorized using conventional schemes as being cardioselective, devoid of intrinsic sympathomimetic activity and having weak membrane-stabilizing and local anesthetic properties. the cardioselectivity of bevantolol was conferred by the incorporation of a 3,4-dimethoxyphenyl moiety into the terminal amino portion of the molecule. this portion of the molecule also appears to account for bevantolol's in vitro binding affinity at alph ... | 1986 | 2871786 |
| beta b1 crystallin is an amine-donor substrate for tissue transglutaminase. | the effects of tissue transglutaminase on the water-soluble proteins in bovine lens homogenates are described. addition of liver transglutaminase and ca2+ to calf lens homogenates resulted not only in the appearance of 50- and 57-kda dimers, but also in a decrease in the amount of beta b1 crystallin and the almost complete disappearance of beta b3 and beta a3. this is not the result of ca2+-induced proteolysis, since histamine completely inhibits this phenomenon. it may be concluded that these p ... | 1987 | 2887447 |

| effect of sodium polyanetholesulfonate and gelatin on the recovery of gardnerella vaginalis from blood culture media. | sodium polyanetholesulfonate (sps) is used as a routine supplement to blood culture media to enhance recovery of microorganisms, but it inhibits the growth of peptostreptococcus anaerobius, neisseria meningitidis, neisseria gonorrhoeae, and streptobacillus moniliformis. comparative clinical blood culture studies at the university of colorado hospital suggested that sps also inhibits the growth of gardnerella vaginalis. we inoculated 16 blood culture isolates of g. vaginalis into 11 blood culture ... | 1985 | 2987298 |

| induction of gene amplification by arsenic. | arsenic is a well-established carcinogen in humans, but there is little evidence for its carcinogenicity in animals and it is inactive as an initiator or tumor promoter in two-stage models of carcinogenicity in mice. two arsenic salts (sodium arsenite and sodium arsenate) induced a high frequency of methotrexate-resistant 3t6 cells, which were shown to have amplified copies of the dihydrofolate reductase gene. the ability of arsenic to induce gene amplification may relate to its carcinogenic eff ... | 1988 | 3388020 |

| metabolic inhibition of peptostreptococcus anaerobius decreases the bactericidal effect of hydrogen peroxide. | peptostreptococcus anaerobius vpi 4330-1 was tested under various conditions for examination of the bactericidal effect of hydrogen peroxide. the cells were most rapidly killed by hydrogen peroxide when they were in the exponential-growth phase. cooling or starving the cells decreased the bactericidal effect of hydrogen peroxide. the ionophore nigericin and the metal ion chelating agent 2,2'-bipyridine stopped macromolecular syntheses and greatly decreased the bactericidal effect of hydrogen per ... | 1981 | 6173014 |
