To identify Kraft liquor effects on spermatogenesis and sperm motility of Caspian kutums by using in vitro culture, the fish testis was incubated with 5, 10 and 15 % (V/V) of liquor for 3 and 6 days. The percentage of motile spermatozoa and its total duration were also measured. Adverse effects on testicular cells were more apparent with the increase of liquor concentrations. The mean size of s...

To determine the optimum culture duration for porcine growing oocytes (GOs) to attain maturation competence, we examined the meiotic competence, chromatin configuration, and fertilization ability of porcine oocytes obtained from early antral follicles and cultured for 10-16 days. The survival rate of oocytes after 10 days of culture (62.8%) was similar to that of oocytes after 12 days of cultur...

PURPOSE To determine whether one can detect hypoxic-ischemic brain injury by MR in the first 10 days of life and to identify patterns of injury in affected neonates. METHODS Standard T1- and T2-weighted MR sequences that were performed in the first 10 days of life in 20 patients who suffered hypoxia/ischemia in the intrapartum or neonatal periods were reviewed retrospectively. Images were eva...

the aim of the present study was to compare the occurrence and duration of clinical mastitis in different seasons, stages of lactation period and parities in a holstein dairy farm in iran. a retrospective epidemiological survey from april 2005 to march 2008 was conducted on 884 clinical mastitis cases of 7437 lactations. data of each case including calendar-date of mastitis onset, days in milk ...
