Opsonized yeast phase Candida albicans, incubated with human neutrophils, are internalized into two classes of phagosomes. One class, termed "unsealed vacuoles," comprises approximately 40% of the total and maintains functional communication to the cell's exterior that is sufficient to permit ingress of dyes, such as trypan or methylene blue. The remaining cell-associated yeasts are contained i...

The cytotoxic events leading to lysis induced in Ehrlich ascites tumor (E.A.) cells by Prymnesium parvum cell extracts were followed microscopically and measured quantitatively as changes in E.A. cell volume, uptake of trypan blue, and release of macromolecular constituents from the cells. Cell swelling was the most immediate response to P. parvum cytotoxin, while cell death and lysis were late...

Synthetic organic textile dyes are recalcitrant compounds released directly by the textile processing units into water bodies are important class of water pollutants. Decolourization of textile diazo dye Trypan Blue (Direct Blue 14) was investigated using a strong oxidative agent sodium hypochlorite using chemometric tools. Statistical tools such as Box-Behnken Design was applied for the study ...

The aim of this research is to assessment the effect oxidase silver nanoparticles outside body organism by exposure samples diagnosed using modified acid fast stain and microscopic isolated examination floatation into three concentrations per nano-material is(01, 0.03 0.05). And then examined at half an hour after trypan blue later calculate living dead oocytes (hemocytometer) percentage oocyst...

introduction: it has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. the effect of platelets on the induction of apoptosis in tumor cells is largely unknown. materials and methods: to investigate this effect, two human hematologic cell lines, k562 and daudi, were independently faced with unstimulated and thrombin-ac...

To obtain basic information on the detection of cellulolytic activity in Auricularia auricula-judae, the influences of dye reagent, pH, and temperature were assessed. Chromogenic dye (congo red, phenol red, remazol brilliant blue, and trypan blue) was individually incorporated into a medium containing either carboxymethyl-cellulose, Avicel, or D-cellobiose as a polysaccharide carbon substrate. ...
