abstract in the present research the effect of different concentrations of cr3+ on growth and uptake of chromium by mycelium of agaricus bisporus was investigated. chromium playes an important role in improvment of insulin action in diabetic patients. the aim of this research was to investingate tolerance threshold of the fungus to cr3+ concentrations. mycelium of a. bisporus was cultured in so...

background: flow cytometry is a rapid, sensitive, and reliable method for determination of bacterial viability. here we assayed the capability of flow cytometry to detect helicobacter pylori viable cells in both forms of spiral and coccoid. methods: viable bacteria stained with rhodamin 123 and fluoresced with laser beam of 488nm. the rate of rh123 absorption was determined in both forms of bac...

rarely, do we think of cancer as “bacterial”, such that we are often told that “cancer is not contagious” persistent bacterial infections cause persistent irritation of the host’s defense systems, which when ineffective in eradication of the infection, result in a multitude of self-destructive damages. this in some cases occurs to such severity that the resulting cellular hyper-proliferation pr...

meningitis is one of the hazardous and life threatening infections and is associated with mortality and morbidity. the aim of this study was to determine etiological agents of childhood bacterial meningitis. the culture, gram staining, agglutination and pcr assays were used to examine csf specimens from 277 patients with presumed bacterial meningitis for the occurrence of 4 most common infectio...

Our laboratory has been working for the last several years with bacterial strains (designated as 1B-A, 1B-C, 1B-E, and 1D-3) isolated from South Dakota wheat foliage and residue which are able to antagonize Fusarium graminearum in laboratory plate assays and in field plot trials. Although we have known for many years that the bacterial strains are endospore formers that are able to grow aerobic...

Soils of the South African sugar industry were first mapped on the basis of soil parent material and were subsequently grouped into forms and series in the binomial system. An integrated system incorporating both these methods has now been developed to enable the cane grower to identify his soils without difficulty. Introduction In South Africa, sugarcane is grown under a range of climatic and ...

Background Diabetes mellitus (DM) refers to a group of common metabolic disorders, with multiple causes, that share a common phenotype: hyperglycemia (Kota, 2012). The concept of multiple etiologies is recent and a third group of DM is proposed today, a monogenic form with autosomal dominant inheritance: MODY. There are 13 subtypes described for MODY, which in MODY2 is one of the most common, a...
