In the view of transmutation of transuranium (TRU) elements, molten salt fast reactors (MSFRs) offer certain advantages compared to solid fuelled reactor types like sodium cooled fast reactors (SFRs). In the first part these advantages are discussed in comparison with the SFR technology, and the research challenges are analyzed. In the second part cycle studies for the MSFR are given for differ...

Objective To determine general attitudes of fertile and infertile women to oocyte donation in a Muslim and secular population. Methods The participants consisted of fertile women (n=133) who had at least one healthy living child spontaneously conceived without any fertility treatment and infertile women (n=133) who were diagnosed with primary infertility. Both groups were evaluated with chart...

background :  young chickens are more susceptible to salmonella colonization than older ones that have developed resistance with age as native microflora become established.   methods :  in this study, two groups of fertile eggs were inoculated with 20 cfu of hila or parent strains of s . enteritidis . presence and number of salmonella cells inside the homogenized egg contents were determined on...

BACKGROUND To examine human microRNA expression in fertile men and subsequently to compare expression patterns of miRNAs in fertile and infertile men, specifically men with Sertoli Cell Only (SCO) histopathology. METHODS Testicular tissues from men with azoospermia and SCO, as well as those of men with normal spermatogenesis, were analyzed. MicroRNA was isolated using the miRCURY™ RNA Purific...

OBJECTIVE To investigate: 1) the impact of clinical varicocele on reactive oxygen species (ROS) levels in neat and washed semen in a proven fertile population; and 2) the correlation between ROS levels, testicular volume, and varicocele grade in the same population of fertile men. DESIGN Prospective controlled clinical study. SETTING Andrology laboratory at tertiary-care hospital. PATIENT...

Inhibin is produced by Sertoli cells of the testis, provides negative feedback on FSH secretion, and may prove to be an important marker for the functioning of seminiferous tubules. The purpose of this study was to examine the relationship between the spermatogenic function of the tests of subfertile men and the plasma concentrations of inhibin. The study was carried out on twenty infertile (or...

The present study was aimed to assess the potential of infertility to induce the adverse effects with reference to testosterone, Triiodothyronine (T3), Thyroxine (T4), Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), zinc, copper and iron. All the samples were divided into four groups according to age and disorder (Group 1, 10 infertile men of 25 40 years; Group 2, 10 fertile m...
