| production and chemical studies of protease from bacillus subtilis (sh-6) egyptian strain. | bacillus subtilis (sh-6) egyptian strain, isolated from hides, gave the highest protease activity. luxurious growth and protease production were obtained by the use of a medium containing 8% of potato starch, 0,1 m of ammonium phosphate as carbon and nitrogen sources. results indicate that borate buffer exerted a deleterious effect on the protease production. comparing citrate and phosphate buffers, it was found that citrate gave lower protease activity than phosphate. there is a positive respon ... | 1978 | 98932 |

| electron microscopy of synaptonemal complexes in semithin sections. | the technique of osmium tetroxide fixation followed by a treatment with p-phenylenediamine was applied to mouse testes in order to analyze pachytene nuclei. observation of epon semithin sections (0.25--0.5 micrometer) in conventional electron microscopy revealed the presence of positively stained synaptonemal complexes surrounded by unstained chromatin. the present results show that by using this method a suitable contrast and resolution can be achieved for semithin sections, which facilitates t ... | 1979 | 156471 |
| myasthenia gravis and lymphoma. a clinical and immunological association. | myasthenia gravis and lymphoma rarely coexist, but the occurrence of myasthenia shortly after the treatment of a patient with poorly differentiated nodular lymphoma suggested that an immunological disorder may have contributed to the development of both diseases; the fundamental defects in this association may be impaired immunological surveillance and impaired regulation of immune responses to autoantigens. the finding of t-cell immunodeificiency, including profound t-cell lymphopenia, impaired ... | 1979 | 314993 |
| nitrate reductases of escherichia coli: sequence of the second nitrate reductase and comparison with that encoded by the narghji operon. | the structural genes for nrz, the second nitrate reductase of escherichia coli, have been sequenced. they are organized in a transcription unit, narzywv, encoding four subunits, narz, nary, narw and narv. the transcription unit is homologous (73% identity) to the narghji operon which encodes the genes for nra, the better characterized nitrate reductase of this organism. the level of homology between the corresponding polypeptides ranges from 69% for the narw/narj pair to 86% for the narv/nari pa ... | 1990 | 2233673 |
| effect of cyclosporin a immunosuppression on primary lymphotropic herpesvirus infection in the guinea pig. | female guinea pigs pretreated for 2 days with cyclosporin a (csa), were then inoculated intranasally (in) or intraperitoneally (ip) with a lymphotropic herpesvirus (gphlv) and followed by 4 additional daily doses of csa. immunosuppressed animals did not show lymphocytosis and virus infectivity titers in their spleen, cervical lymph node and blood mononuclear cells were lower than those of oil-treated controls. while in-inoculated csa-treated animals expressed higher virus infectivity titer in th ... | 1987 | 2832345 |
| ryanodine: its possible mechanism of action in the caffeine-sensitive calcium store of smooth muscle. | the caffeine-sensitive intracellular ca store was characterized and the mechanism of action of ryanodine in the store was studied using k-depolarized guinea-pig taenia caecum. (1) after incubation of the preparation with cacl2 (ca loading), caffeine was applied in ca-deprived medium, to produce a transient contraction and to monitor the amount of the stored ca. as duration of ca deprivation was prolonged, the amplitude of the caffeine-induced contraction was decreased. when ryanodine was applied ... | 1988 | 3174395 |
| flow distribution between the endocrine and exocrine parts of the isolated rat pancreas during perfusion in vitro with different glucose concentrations. | previous studies in our laboratory have indicated that pancreatic islet blood flow is stimulated by glucose. in an attempt to evaluate to what extent intrapancreatic control mechanisms are involved in the glucose modulation of islet blood flow the distribution of flow between the endocrine and exocrine parts of the rat pancreas during perfusion in vitro with different glucose concentrations have now been studied. for this purpose pancreatic glands from 29 rats were perfused at a flow rate of 1.5 ... | 1986 | 3521204 |

| a linear muscle model predicts the hyperbolic force-velocity relationship. | a variety of different schemes have been reported in the literature for linearizing the force-velocity relationship observed in muscle, a dominant element in the muscle. this report extends assertions that a linear muscle system has force-velocity characteristics as described by hill's hyperbolic equation, and that no linearization whatsoever is required. the muscle is modeled as a parallel combination of passive elasticity, and series elasticity connected to the parallel combination of active s ... | 2007 | 2742961 |
