In this study, montmorillonite clay was used as the adsorbent for the removal of Aniline Blue dye, from aqueous solution by the batch adsorption technique under different conditions. The maximum removal of aniline blue dye for initial dye concentration 20 mg/L was more than 95% at optimum conditions (pH=4.5, contact time=30 min, and adsorbent dosage=2 g/L). The data of this study were fitted wi...

background: current microscopic experimental methods cannot diagnose dna damages present in spermatozoa .therefore, some methods are needed to address the abnormality of the genetic material status on the sperm samples. as reported by many investigators aniline blue staining technique has been used for identifying sperm chromatin condensation. also, chromomycin a3 is used for evaluation of the ...

The main purpose of this study was to determine the possible relationship between chromatin condensation (Aniline Blue staining), the morphology of spermatozoa according to strict criteria, and the fertilization, cleavage and pregnancy rate in an intracytoplasmic sperm injection (ICSI) programme. A total of 60 patients were divided into two groups (27 versus 34) according to sperm stainability ...

introduction: the novel development of the (hba) sperm- hyaluronan binding assay has now been routinely used in some laboratories worldwide to predict sperm maturity and functionality. the purpose of this study was to evaluate the correlation between hba score and histone deficiency, protamine content and dna fragmentation. methods: during april- march 2012 patients who were enrolled at shiraz-...

The present study focuses on predicting the concentration of intracellular storage polymers in enhanced biological phosphorus removal (EBPR) systems. For that purpose, quantitative image analysis techniques were developed for determining the intracellular concentrations of PHA (PHB and PHV) with Nile blue and glycogen with aniline blue staining. Partial least squares (PLS) were used to predict ...

The aim of this study was to determine whether sperm morphology and nuclear maturity are associated with an increase in the prevalence of disomy in human spermatozoa. Semen samples were obtained from 60 patients selected at random from a population of men undergoing semen analysis as part of consultation for infertility. Semen analysis and aniline blue staining were carried out on each ejaculat...

In this work, we highlight effects of pH on bacterial phenotypes when using the bacteriological dyes Aniline blue, Congo red, and Calcofluor white to analyze polysaccharide production. A study of galactose catabolism in Sinorhizobium meliloti led to the isolation of a mutation in dgoK1, which was observed to overproduce exopolysaccharides when grown in the presence of galactose. When this mutan...

Brewer's yeast (bottom yeast, Saccharomyces cerevisiae subsp. uvarum) cells were magnetically modified using water based magnetic fluid stabilized with perchloric acid. Magnetically modified yeast cells efficiently adsorbed various water soluble dyes. The dyes adsorption can be described by the Langmuir adsorption model. The maximum adsorption capacity of the magnetic cells differed substantial...

Subfossil chironomids are regarded as a useful biological proxy for palaeoenvironmental research, but picking chironomid head capsules from aquatic sediments is extremely time-consuming. This often the case finding and isolating small deflocculated sediment. In this study, two stains (aniline blue cotton blue) were used to dye in lake peat improve traditional pretreatment method boost efficienc...
