Background This novel approach describes a rapid and simple method for identification of necrotic vs. viable cells within a mammalian blastocyst. MaterialsAndMethods Hatched bovine blastocysts produced in vitro were first incubated for 30 min in pre-equilibrated culture medium containing propidium iodide (PI; 300μg/ml) and bisbenzimide (Hoechst: H33342; 5μg/ml) fluorescent dyes. Embryos were th...

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-...

chromosomal appearance of 12 holstein bulls selected for artificial inseminations were examined bysister chromatid exchanges (sces). for differential staining of sister chromatids bromodeoxyuridine (brdu)was inoculated in lymphocyte cultures. the mean, maximum and minimum number of sce per cell weredetermined 6.8 ± 1.14, 8.3 ± 1.1 and 5.7 ± 1.5, respectively. sce frequencies of all animals were...
