Alzheimer’s disease (AD) is a neurodegenerative brain disorder which has no effective treatment yet due to the blood barrier in the brain that limits the drugs with the potential of disease improvement. Extracellular vesicles (EVs) are biocompatible nanoparticles with a lipid membrane. These vesicles are secreted from various cells such as mesenchymal stem cells (MSCs) and can pass through biol...

Background: Disturbance of the gut microbiota may play a critical role in progression nonalcoholic fatty liver disease (NAFLD) induced by high-fat diet (HFD). Changes were analyzed rat HFD-induced NAFLD model following treatment with Qinghua Fang (QHF), Chinese herbal formula currently used clinical practice traditional medicine.
عضله رحم rat از نظر ساب تایپ های رسپتور p1 پورینرژیک مورد بررسی قرارگرفت . به این جهت آدنوزین و آنالوگهای آن مورد بررسی قرار گرفتند . نتایج بدست آمده نشان میدهند که آثار مهاری آدنوزین و آنالوگهایش بر روی دامنه انقباضات الکتریکی رحم rat بواسطه هیچیک از ساب تایپ های a1 و a2 صورت نمیگیرد، بلکه اینکار از طریق ساب تایپ جدیدی از رسپتور p1 انجام میگیرد. ترکیباتی که درموقعیت 5 حلقه ریبوزاستخلاف دارند (...
Introduction: Parkinson's disease (PD) is among the most common neurodegenerative disorders. Given the powerful antioxidant effects of the saffron extract on the removal of free radicals, this study aimed to investigate the protective effects of the saffron extract on reducing oxidative stress in a rat model of Parkinson's disease pretreated with saffron. Materials & Methods: In this experim...
At-home rapid antigen test (RAT) kits for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are valuable public health tools during the present disease (COVID-19) pandemic. They provide fast identification of infection, which can help to reduce transmission rates and burden on healthcare system. However, they have lower sensitivity compared reverse transcription polymerase chain reac...
سیستم هیستامینرژیک مرکزی دارای تاثیرات تنظیمی بر رفتارهای شبه اضطرابی هم در حیوانات و هم در انسان است. این تاثیرات از طریق رسپتور h1 و h2 میانجیگری میشود. تست epm(elevatd plus-maze( برای بررسی تاثیرات اضطراب زایی یا اضطراب زدایی داروها در جوندگان بکار میرود. شواهد نشان می دهند که فعالیت (bnst) bed nucleus the stria terminalis رفتار شبه اضطرابی را در انسانها و حیوانات تنظیم می کند. در مطالعه حاض...
Obesity is a disease whose incidence has increased over the last few decades. Despite being multifactorial disease, obesity results essentially from excessive intake of high-calorie foods associated with low physical activity. The demand for pharmacological therapy using natural compounds as an alternative to synthetic drugs increased. Natural may have adverse effects and high economic impact, ...
Background and Objectives: Alzheimerchr('39')s disease (AD) is a neurodegenerative disease which is marked by impaired cholinergic function and decreased nicotinic acetylcholine receptor (nAChRs) density. nAChRs are important mediators of cholinergic signaling in modulation of learning and memory function. In Alzheimer hippocampus is particularly vulnerable to specific degenerative processes an...
Background & Objective: Multiple sclerosis (MS) is a demyelinating disease of central nervous system, which is approximately two to three times more common in women than men. It was suggested that sexual hormones affect MS disease. Over half of MS patients have cognitive deficits, including learning and memory dysfunction. Estrogen also influences most of the cerebral function including l...
