Studies on the fractionation of blood serum by Cohn et al. (1) have demonstrated that under precisely controlled conditions reproducible fractionation of a complex mixture of proteins can be accomplished by the use of ethanol. This paper reports the application of this method to the separation of hyaluronidase from testicular extract. A variety of experimental conditions involving variation of ...
Background: Staphylococci are recognized worldwide as one of the most important etiological agents of bovine mastitis due to their virulence factors such as their ability to penetrate inside mammary epithelial cells and their ability to form biofilm. Aims: The objectives of this study were to establish a model of primary mammary epithelial cells origin...
Background & Aims: Increase of blood glucose levels leads to structural and functional changes in reproductive system. This investigation was conducted to evaluate the effects of diabetes on the structure and function of testicular tissue focusing on the ultrastructure of the epithelium of seminiferous tubules. Materials & Methods: Diabetes was induced in adult male rats by single intraperiton...
background and objective: pneumocystis pneumonia (pcp) has been historically the most prevalent opportunisticinfection in patients infected with the human immunodeficiencyvirus. culture of the organism has not been faced with suitable success in artificial media, while various results have been reported for cell culture media. the aim of this study was proliferation of pneumocystis carinii on t...
The reactions of purified, homogeneous bovine testicular hyaluronidase have been studied with radioactively labeled oligomers of hyalobiuronic acid, (GlcUA-GlcNAc),, as substrates and acceptors. Transglycosylation occurs by transfer of a glycosyl residue with retention of configuration from a leaving group to an acceptor. On the basis of detailed examination of cleavage and transglycosylation p...
Abstract Introduction: Researchers usually search for medications of infertility. Hence, this study was done to determine the effects of L-Carnitine and exercise on histological changes of testicular tissue after Boldenone steroid use in male rats. Objective: Assessment of the effects of L-Carnitine with Endurance training after Boldenone use on testicular tissue changes in male rats. Materi...
Onconase (ONC) and bovine seminal ribonuclease (BS-RNase) are homologs of bovine pancreatic ribonuclease (RNase A). Unlike RNase A, ONC and BS-RNase can evade the cytosolic ribonuclease inhibitor protein and are potent cytotoxins. Here, the endogenous cytotoxic activities of ONC and BS-RNase are compared in a wide variety of assays. Injections of ONC into one or both testes of mice and rats evo...
The receptors 1 and 2 of fibroblast growth factor (FGFR1 and FGFR2, respectively) have been observed in all types of testicular cells. Culture on extracellular matrix (ECM) has been observed to lead to initiation of differentiation in spermatogonial stem cells (SSCs). The present study was carried out to investigate whether FGFR1 and FGFR2 play a role in SSCs differentiation. Following isolatio...
