A new method is described for the enzymatic preparation of testicular tissue to obtain vital spermatozoa for ICSI. The tissue obtained from both testes by biopsy is studied by means of the semi-thin section method as well as being cryo-preserved. If spermatid formation is assured by semi-thin section histology, vital spermatozoa from the cryo-preserved portion of testicular tissue are enzymatic...

BACKGROUND Estrogens are involved in masculine fertility and spermatogenesis. However, little is known about estrogen involvement in human testicular organogenesis. Therefore the aim of this study was to investigate the cellular sources and targets of estrogens and their variations in the human testis during fetal development. Expression profiles of aromatase (CYP19) and estrogen receptors (ER)...

background: the current study aimed to evaluate the effects of phosalone (pln) as an organophosphate (op) compound on testicular tissue, hormonal alterations and embryo development in rats. materials and methods: in this experimental study, we divided 18 mature wistar rats into three groups-control, control-sham and test (n=6 per group). animals in the test group received one-fourth the lethal ...

I do appreciate your advice. It will be extremely useful in our next studies. 1. Material&Method section a. The content of the plants rather than the rate of herbal mixtures used in the study should be presented as a table. KH-204 is a commercial product registered as a herbal formula for 'improvement in penile erection and lasting effect'. Therefore, the detailed content of herbal mixture is s...

Germ cell tumors (GCT) are curable cancers, but 10-15% of patients with metastatic disease fail cisplatinbased first-line therapy. While therapeutic options have increased for various other cancers no therapeutic targets have emerged in cisplatin-refractory GCT. L1 cell adhesion molecule (L1-CAM) is commonly expressed in human malignancies and therefore a potential target, however its expressio...

Pendrin (PDS) and sodium/iodide symporter (NIS) are transmembrane proteins that are located in numerous tissue types, particularly thyroid follicular epithelial cells, where they are entrusted with the regulation of iodine molecules. In the present study, we aimed to clarify changes in PDS and NIS protein expression, in the testicular tissue of prepubertal and <span la...

Alternative pre-mRNA splicing (AS) is a key molecular event that allows for protein diversity and plays important roles in development and disease. AS regulations during spermatogenesis and AS aetiology in testicular tumorigenesis have not yet to be characterized. By genome-wide analysis, here we describe alternative splicing features that distinguish distinctive patterns of AS among human test...

The present study investigated the impact of zinc oxide nanoparticles (ZnONPs) on the oxidative status and sperm characteristics in diabetic rat testicular tissue. Forty male albino rats were used in this study; 10 of them served as a control and 30 rats were injected with a single dose (100 mg/kg) of streptozotocin intraperitoneally. They were subdivided into diabetic, diabetic + ZnONPs (10 mg...
