Monoclonal antibodies (mabs) have been used as a powerful tool for identification of newer sperm proteins. However, conventional hybridoma technology rarely provides chance to obtain mabs to epididymal proteins. To increase this chance, we have used an alternate method of neonatal tolerization. In this protocol, animals were tolerized at birth using testicular proteins followed by immunization ...
The aim of the present study was to investigate the androgen receptor (AR) distribution in epididymal cells of developing rats and the effects of prepubertal epididymal obstruction upon AR distribution in the rat caput epididymis. At 15 days of age, the young rats were divided at random into groups for epididymal ligation or sham operation. In the ligation group the corpus epididymides were lig...
Insulin action on glucose transport and metabolism was studied in paraovarian adipocytes from 3-month-old female rats and compared with insulin action in epididymal adipocytes from closely age-matched males. At maximal insulin concentrations the stimulations of 2-deoxyglucose uptake (4-fold the basal value) and of [U-14C]glucose incorporation into CO2 and total lipids (3- and 2-fold the basal v...
Two cases of epididymal sarcoidosis, presenting as scrotal masses, are described. Biopsies of the epididymis and scalene nodes established the diagnosis. The literature of epididymal sarcoid and its differential diagnosis is discussed.
Sperm samples may be used for assisted reproductive technologies (e.g., farmed or endangered species) or as a source of haploid DNA or sperm-specific RNA. When ejaculated spermatozoa are not available or are very difficult to obtain, as is the case for most wild endangered species, the epididymides of dead animals (e.g., animals that have been found dead, shot by hunters or poachers, or that th...
The proteins of epididymal tissues and fluids recovered from different regions of the mouse epididymis from a natural population and an inbred line were examined by polyacrylamide gel electrophoresis under denaturing conditions. Two epididymal specific peptides on the order of 88 and 20 Kilodaltons (Kd), undetected in serum and testicular extracts, were identified in the initial segment, caput,...
Introduction: Thyroid hormones are involved in the regulation of hydrogen sulfide (H2S) biosynthesis. The aim of this study is to determine effects of thyrotoxicosis on H2S levels and mRNA expression of cystathionine-β-synthase (CBS), cystathionine-γ-lyase (CSE) and 3-mercaptopyruvate sulfurtransferase (3-MST) in the adipose tissue of rat. Materials and Methods: Male rats were divided into the ...
the effects of ex vivo cold-storage on cryopreservation of the goat (caprus hircus) epididymal sperm
background: there are many studies focused on long or short storage time of epididymal sperm (eps) of different species. there are limited studies on preservation or cryopreservation of the domestic goat eps. objective: the aim of the present study was to evaluate the effects of ex vivo cold-storage on freezing of eps from goat (capra hircus). materials and methods: in a split-plot design the c...
