The Effect of Green Tea (Camellia Sinensis) on Rat Testicular Tissue Following Exposure to ParaNonylphenol

Background & Aims: Para-Nonylphenol (p-NP) can cause oxidative stress through reducing the activity of scavenging enzymes. The aim of the present study was to investigate the effect of green tea extract, as an antioxidant, on testisin rats exposed to p-NP. Methods: In the present study, 24 Wistar rats with mean body weight of 215 ± 10 g were divided into 4 groups (n = 6)...

Effectiveness of Bench Top Non-Vacuum Autoclaves on Dental Turbine Chamber Sterilization

Introduction: Dental turbine chamber is a suitable reservoir for living microorganisms, so chamber sterilization is necessary for reducing cross contamination risk. On the other hand, in non-vacuum autoclaves, steam penetration into turbine chamber is doubtful, while they are still in use in dental clinics. In this study, performance of small non-vacuum autoclave in turbine chamber sterilizatio...

A Comparison of Fundamental Performance between Two Bench Top Clinical Chemistry Analyzers

Overexpression of Recombinant Human Beta Interferon (rhINF-β) in Periplasmic Space of Escherichia coli

Human Interferon β (INF-β) is a member of cytokines family which different studies have shown its immunomodulatory and antiviral activities. In this study an expression vector was designed and constructed for expression of human INF-β-1b either in shake flasks and bench top bioreactor. The designed vector was constructed based upon pET-25b(+) with T7 promoter. Recombinant human beta interferon ...

مطالعه استریولوژیکی اثر حفاظتی روغن سیاه‌دانه بر بافت بیضه موش بدنبال سمیت القا شده توسط پارانونایل‌فنل

Background & Aims: Para-Nonylphenol (p-NP) is an estrogenic compound with toxic effects on the various organs including testis. The purpose of this investigation was to study the toxic effects of p-NP on the testis tissue of mice and evaluation of the effect of Nigella sativa oil (NSO) against this toxicity Materials & Methods: This study was conducted on 24 adult male NMRI mice (32&plu...
