Abstract Non-alcoholic fatty liver disease (NAFLD) is a metabolic dysfunction of the defined as an abnormal accumulation fat within without secondary triggers like alcohol consumption or viral hepatitis. Piperine, bio-active ingredient black pepper, can exert significant function in treatment individuals with NAFLDand early cirrhosis. We investigated impact piperine duration 12 weeks on patients NAFLD and cirrhosis compared toplacebo consumption. In double-blind study, stage were haphazardly...

Prostate cancer (PC) is one of the most abundant cancers among men, and In Iran, has been responsible for 6% all deaths from in men. NUF2 GMNN genes are considered as loci susceptibility to tumorigenesis humans. Alterations expression these have reported various malignancies. The aim our study was test whether different levels associated with PC incidence hence, might be new molecular tools screening.Biopsy samples 40 patients 41 healthy Iranian men were used determine relative gene...

Abstract Background Rheumatoid arthritis (RA) is the most common cause of systemic inflammatory which causes joint destruction. The pathogenesis RA not fully understood, but it seems imbalance between oxidant and antioxidant process, plays a significant role on it. As result, suppression these mechanisms would be helpful to subside inflammation eventually control disease activity. aim this study was evaluate level their effects activity in patients. Methods In following case-control study,...

Abstract Heterogeneous catalysts were developed by supporting palladium nanoparticles on modified cross‐linked polyacrylamide and successfully applied in Suzuki‐Miyaura cross‐coupling reactions. These are stable to air moisture, no sign of metal leaching was detected during the reactions as judged elemental analysis ICP‐OES technique hot filtration test, which demonstrates heterogeneous character catalysts. High yields desired products resulted using these phosphine‐free at temperatures...

Prostate cancer is the second most common in men Iran. It can be treated early stages of disease; therefore, diagnosis lifesaving. The aim this study was to investigate molecular expression some oncogenes and predisposing behaviors contributing aggressiveness prostate cancer.In case-control study, specimens were collected from both patients healthy volunteers. Several factors such as age, family history, smoking, stage disease, investigated based on criteria study. Real-time PCR used measure...

Background: Women with type 2 diabetes are more susceptible to coagulopathy disorders and endothelial dysfunction. One possible explanation is the effects of different sex hormones in inflammatory conditions. Increased plasminogen activator inhibitor-1 (PAI-1) activity has been observed as a predisposing factor for However, effect gender on PAI-1 patients (T2D) albuminuria not studied sufficiently.Objectives: In this study, we examined whether changes according state males females.Materials...

Dear Sir, Ramadan is a month of fasting for Muslims, on April 23. The appearance within the COVID-19 pandemic leads to patients and clinicians asking questions about safety in month. We research effects different immune system mechanisms that we guess whether safe patient or not? Some studies demonstrated macrophage activity, monocyte level immunoglobulin A intestinal mucosa, natural killer-cell activity were increased during fasting.[1] Another study reported concentration tumor necrosis...
