The leukocyte-phagocytic function test which was found to be abnormal in boys with fatal granulomatous disease of childhood has been found to be abnormal to an intermediate extent in their mothers. Nine of nine mothers were shown to be abnormal, whereas none of eight fathers and none of five healthy brothers exhibited a defect. 10 of 16 female siblings were abnormal to the same degree as their ...

I evaluated a semi-automated method for measuring glycohemoglobin via reduction of nitroblue tetrazolium by acetone-extracted globin. The simultaneous measurement of glycated protein and total protein with the Roche Mira S analyzer showed good analytical precision (between-batch CV 3.5%-8.5%). Correlation of results (y) with those by a boronate affinity chromatography method (x) gave a regressi...

Multiple in vitro tests are widely applied to assess the anticancer activity of new compounds, including their combinations and interactions with other drugs. The MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay is one of the most commonly used assays to assess the efficacy and interactions of anticancer agents. However, it can be significantly influenced by compounds t...

In recent years, there has been increased interest in the use of nanostructures various industries, such as food, textile, pharmaceutical, electronics, and chemical industries. Most these applications require a proper preparation specific nanomaterials. this study, we characterized silver nanoparticles (AgNPs) stabilized with polyvinylpyrrolidone prepared aqueous suspensions using dynamic light...

candida albicans has the ability to change between yeast and hyphal cells and is known to be a virulence property. efg1gene of c.albicans is as a main transcription factor that plays pivotal roles in biofilm formation the aim of the current study is to investigate the presence of efg1 gene in candida albicans isolates from women with vaginal candidiasis and its impact on biofilm formation.we us...

Conditions were assessed which would permit more rapid recognition of bacterial growth than has been previously reported using tetrazolium salts. Microtitration trays were used. 2-(p-Iodophenyl)-3(p-nitrophenyl)-5-phenyltetrazolium chloride is rapidly reduced by respiring cells in tissue homogenates but is more toxic than other tetrazoliums when added to growing bacterial cultures. Phenazine me...

ÖZ E T Bu çalışmada tetrazolyum tuzları ve formazanların yapıları tanımlanmıştır. Ayrıca formazan-tetrazolyum sistemlerinin önemi ve kullanım alanları açıklanmıştır. Formazanların sahip oldukları conjugate p-system kaynaklanan tautomerleşme özellikleri ve geometrik izomerleri incelenmiştir. Bu bileşiklerin en yaygın kullanılan sentezleri ve yapılarının açıklanmasında önemli olan UV-visible, IR ...

While trying to develop methods for finding dehydrogenase mutants, we found tetrazolium (triphenyl tetrazolium chloride) to be useful for detecting fermentative variants. This indicator has the advantage that the nonfermenting variants are stained a deep red whereas the fermenters and the background are neutral. For example, cultures of Escherichia coli K-12 were spread on nutrient agar plates ...

TiNi shape memory alloy (SMA) prepared by laser solid forming (LSF) has wide application prospect and research value. In this work, LSF-Ti49.2Ni50.8 was tested X-ray diffraction (XRD), differential scanning calorimetry (DSC), transmission electron microscopy (TEM). The microscopic characterization results show that there is a small amount of martensitic slat in besides the substrate. Lenticular...
