Background: Infertility problem affects 20-30% of young couples. One of the known causes of spermatogenesis disorder is chemotherapy in patients with cancer which its side effect may last up to the end of the life. Since dividing cells are mainly affected by anticancer drugs, the aim of the present study is to investigate the preventive effect of GnRH on spermatogenic defect produced by antican...

Background: Testicular cancer (TC) is usually diagnosed after manifestation of an overt tumour. Tumour formation is preceded by a pre-invasive and asymptomatic stage, carcinoma in situ (CIS) testis, except for very rare subtypes. The CIS cells are located within seminiferous tubules but can be exfoliated and detected in ejaculates with specific CIS markers. Materials and Methods: We have built ...

Cis-stereoregulated poly(phenylacetylene) [poly(PA)] was synthesized by polymerization of PA using Rh catalysts, and the thermal isomerization behavior analyzed DSC, 1H NMR, IR Raman spectroscopies. Cis-poly(PA) exhibited DSC exothermic peaks around 170 °C corresponding to main chain from cis trans. The content decreased 12% after heating at °C, became almost zero 180 which determined NMR spect...

The growing interest in alternative fuels based on plant oils has led to the search for new species. Given this, during 2015–2020, oil from 12 varieties of oilseed radish was studied using standard research protocols. average content dominant fatty acids was: [cis-9] oleic (C 18:1) 33.95% (Cv = 14.2%), [cis-9,12] linoleic 18:2) 16.20% 20.8%), [cis-13] erucic 22:1) 15.18% 17.9%), [cis-9, 12, 15]...
