[ 1 ] - Thymoquinone recovers learning function in a rat model of Alzheimer’s disease
Objective: Alzheimer's disease is a neurodegenerative disorder characterized by accumulation of amyloid beta in the hippocampus. In recent decades, herbal medicine has been widely used to treat many neurodegenerative disorders,as in comparison to conventional drugs, herbal remedies exert minimal side effects. Here, the effects of thymoquinone, as the main active component of Nigella sativa, on ...
[ 2 ] - In vitro and in silico studies of the inhibitory effects of some novel kojic acid derivatives on tyrosinase enzyme
Objective(s): Tyrosinase is a key enzyme in pigment synthesis. Overproduction of melanin in parts of the skin results in hyperpigmentation diseases. This enzyme is also responsible for the enzymatic browning in fruits and vegetables. Thus, its inhibitors are of great importance in the medical, cosmetic and agricultural fields. Materials and Methods: A series of twelve kojic acid derivatives wer...
[ 3 ] - اثر تجویز خوراکی نیترات سدیم بر شمارش سلولهای خونی در موشهای صحرایی نر چاق و مبتلا به دیابت نوع 2
مقدمه: دیابت نوع 2 یکی از شایع‌ترین بیماریهای متابولیک است. نیترات به عنوان درمان جدیدی برای دیابت مطرح است. با توجه به اینکه هم دیابت و هم نیترات سدیم بر شمارش سلولهای خونی اثر دارند و حدود 30 درصد افراد دیابتی کم‌خونی دارند، این مطالعه با هدف بررسی اثر نیترات سدیم بر تعداد سلولهای خونی در موشهای صحرایی نر چاق دیابتی نوع 2 انجام شد. مواد و روشها: 48 سر موش صحرایی نر نژاد ویستار به چهار گر...
[ 4 ] - Decreased level of the anti-inflammatory adipokines, secreted frizzled-related protein 5 and adiponectin, in high cholesterol diet-induced atherosclerotic rats
Introduction: The involvement of secreted frizzled-related protein5 (SFRP5) and adiponectin, two important adipokines produced by adipocytes, in cardiovascular diseases demand further assessment. Therefore, in this study the relation of the adipokines and atherosclerosis was evaluated in Rat. Materials and methods: For the study, thirty male Wistar rats were divided into 2 groups (each group c...
[ 5 ] - بررسی تاثیر مهاری ترکیبات آروماتیک بر فعالیت آلفا آمیلاز سرم گاو: جستجوی ترکیبات بالقوه موثر در کنترل قند خون
Background: Alpha-amylase is the most important enzyme in the digestion of starch. Activators of this enzyme could be potentially used as digestive aids and its inhibitors block the absorption of starch compounds and result in the control of blood sugar levels. This study aimed at the investigation of aromatic compounds on bovine serum alpha-amylase. Methods: Effect of carvacrol, cumyl phenol, ...
[ 6 ] - مطالعه نقش گیرنده‌های گابا A در دوران تکوین جنینی بر روی میزان سایتوکاین‌ها در هیپوکامپ و قشر پره‌فرونتال زاده‌ها
سابقه و هدف: در شمار وسیعی از مطالعه ها ارتباط بین التهاب در نواحی مختلف مغز و اختلالات عصبی مثل اضطراب و افسردگی تایید شده است و عامل التهاب باعث افزایش سایتوکاین‌ها می‌شود. از طرف دیگر افزایش سایتوکاین‌ها در ارتباط با اختلالات عصبی مثل آلزایمر، پارکینسون، اضطراب و افسردگی می‌باشد. گاما آمینو بوتیریک اسید (گابا) بزرگترین و مهم‌ترین نوروترانسمیتر مهاری در سیستم عصبی مرکزی پستانداران است هم چن...
[ 7 ] - The effect of Nitrochalcone on biochemical indicators and PPAR-α gene expression in nonalcoholic male NMRI mice steatosis model
Introduction: Non-alcoholic fatty liver disease (NAFLD) is associated with oxidative stress, inflammation, and decrease in peroxisome proliferator-activated receptor alpha (PPAR-α) expression. Nitrochalcone is effective ingredient of chalcones with anti-inflammatory, anti-cancer and anti-hyperglycemic properties. This study examined the effect of intraperitoneal (IP) administration of nitrochal...
[ 8 ] - The effect of cerebrospinal fluid-derived exosomes on neural differentiation of adipose mesenchymal stem cells in alginate hydrogel scaffold
Nowadays, researchers have made extensive efforts to find new treatments for nerve damage. Meanwhile, the role of exosomes in cell-cell communication is considered to be a new mechanism. Exosomes can act as suitable differentiating agents. The aim of this study was to investigate the differentiating effect of cerebrospinal fluid-derived exosomes on adipose mesenchymal stem cells in alginate hyd...
[ 9 ] - The anti-diabetic potential of P-Cymene monoterpene on serum factor levels and SOD assay in STZ-diabetic male rats
Diabetes is a serious public health problem in low- and middle-income countries. There is a strong association between hyperglycemia, oxidative stress and the development of diabetes. Therefore, screening and early diagnosis of this disease in people at high risk can be effective in preventing these complications. The main route of insulin signaling is to control lipid and glucose metabolism, a...
[ 10 ] - Evaluating the effects of metformin on irisin and serum biochemical parameters in male sprague-dawley rats fed by a high-fat emulsion diet
Irisin is a myokine secreted mostly by muscles after exercise, and its secretion level changes in metabolic disorders. The aim of present study was to investigate the effect of metformin on changes in the levels of plasma irisin, blood glucose and insulin resistance in male Sprague-Dawley rats receiving a high-fat emulsion diet. Twenty-four rats were divided into a normal control group (n = 8) ...
