Vitamin C attenuates detrimental effects of diabetes mellitus on sperm parameters, chromatin quality and rate of apoptosis in mice.

Objectives: The main goal was to examine the protective effects of vitamin C on sperm parameters, sperm chromatin condensation and apoptosis in experimentally-induced diabetic mice.

Study Design: 28 adult Syrian mice were divided into 4 groups. In Group1, the mice were diabetic that received a single dose of Streptozocin (STZ) (200mg/kg) intra-peritoneally (ip).

Does women's age influence zona pellucida birefringence of metaphase ΙΙ oocytes in in-vitro maturation program?

Background: In vitro maturation (IVM) is a promising treatment option for certain infertile women. Nowadays, with the aid of PolScope, it has become possible to evaluate zona pellucida (ZP) characteristics as a parameter of oocyte quality. Moreover, quality of oocytes can be influenced by many factors, such as patient's age.

The Effect of Unsaturated Fatty Acids on Molecular Markers of Cholesterol Homeostasis in THP-1 Macrophages.

Background: Macrophages derived foam cells are key factors in the maladaptive immune and inflammatory response.

Objectives: The study of the cholesterol homeostasis and the molecular factor involved in these cells is very important in understanding the process of atherosclerosis and the mechanisms that prevent its occurrence.

Materials And Methods: This experimental study investigated the effects of c9, t11-Conjugated Linoleic Acid (c9, t11-CLA).

Critical thinking ability and its associated factors among preclinical students in Yazd Shaheed Sadoughi University of Medical Sciences (Iran).

Background: The aim of this study was to investigate the ability of Iranian medical and dental students in thinking critically and to assess their ability in using definite components of critical thinking (CT).

Methods: Multistage cluster sampling was utilized to recruit 125 preclinical (1(st), 2(nd) and 3(rd) year of study) students in Yazd Shaheed Sadoughi University of Medical Sciences in Yazd, Iran. The Watson-Glaser Critical Thinking Appraisal (WGCTA) was applied to collect data.
