OBJECTIVE To estimate the female sex worker population size in three cities in Côte d'Ivoire and in Kisumu, Kenya. METHODS Capture-recapture was used, calculating size estimates by first 'tagging' a number of individuals and, through an independent recapture, calculating the proportion of overlap. The same procedures were used in all four cities. In the first phase, members of the target po...
Objective: Reproductive biotechnology studies focus on the longterm storage of embryos (cryopreservation), embryo cultures, genome editing and transfer. Micromanipulation techniques in reproduction biotechnologies have an important role, especially investigating assisted reproductive technology laboratory animals. The aim present study was to investigate effect epididymal spermatozoa injected o...
BACKGROUND In longitudinal studies, nonresponse to follow-up surveys poses a major threat to validity, interpretability and generalisation of results. The problem of nonresponse is further complicated by the possibility that nonresponse may depend on the outcome of interest. We identified sociodemographic, general health and wellbeing characteristics associated with nonresponse to the follow-up...
The development of methods capable of selecting the sex of animals has always been a great challenge for humankind. Separating X chromosomebearing and Y chromosome-bearing sperm based on DNA difference using flow cytometry is the only technique that has achieved a useful level of progress, especially in cattle. This allowed the technique to be commercially applicable in this species. Thorough t...
The objective of this study was to determine whether bovine embryos become more resistant to deleterious effects of maternal heat stress as early embryonic development progresses. Superovulated, lactating Holstein cows were bred by AI and assigned to be heat stressed on d 1, 3, 5, or 7 of pregnancy (d 0 =day of estrus) or not heat stressed (control). Embryos were retrieved from the uterus on d ...

We aimed to investigate the prevalence of Trichomonas vaginalis in diabetic patients referred to diabetic research center. Material and Methods: In this descriptive-analytic study, 215 women referring to the Diabetic Center in Kermanshah Province were invest...
