Ribonucleic acid polymerases of the yeast phase of Histoplasma capsulatum.
Ribonucleic acid (RNA) polymerases of Histoplasma capsulatum (yeast phase) were fractionated by phosphocellulose chromatography and partially characterized. Three distinct, active fractions were seen. The major RNA polymerase species was inhibited strongly by alpha-amanitin, whereas the other two were resistant. When either slightly purified (HSE) extract or the major active component was assay...

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولIdentification and characterization of a phase-specific, nuclear DNA binding protein from the dimorphic pathogenic fungus Histoplasma capsulatum.
Genes expressed in the parasitic yeast (Y) phase of the dimorphic fungal pathogen Histoplasma capsulatum which are transcriptionally silent in the mycelial (M) phase have recently been cloned and analyzed. To understand the molecular regulation of genes involved in the transition to and maintenance of the Y phase, the presumptive 5' regulatory regions of two Y phase-specific genes (yps-3 and yp...
متن کاملCharacterization of the Histoplasma capsulatum-induced granuloma.
Rising rates of Histoplasma capsulatum infection are an emerging problem among the rapidly growing population of immune-compromised individuals. Although there is a growing understanding of systemic immunity against Histoplasma, little is known about the local granulomatous response, which is an important component in the control of infection. The focus of this article is the characterization o...
متن کاملProbing the yeast phase-specific expression of the CBP1 gene in Histoplasma capsulatum.
Histoplasma capsulatum is a pathogenic fungus that exists in two distinct forms. The saprophytic mycelial phase inhabits moist soil environments; once inhaled, hyphae and conidia convert to a unicellular yeast phase that is capable of parasitizing macrophage phagolysosomes. Yeasts cultures, but not mycelial cultures, release large quantities of a calcium-binding protein (CBP) which may be impor...
