objectives: leptin is a hormone-like protein produced by the adipose tissue. it plays an important role in protection of host against inflammation and infection. some studies have reported changes in leptin levels in the gingival crevicular fluid (gcf), saliva and blood serum of patients with periodontal disease compared to healthy individuals. the aim of the present study was to compare the sa...

abstract        background and objective: peroxidases catalyze protein oxidation and lipid peroxidation. the activity of these enzymes in nerve cells is involved in causing disorders such as alzheimer's and parkinson's disease. this study investigated the effect of citrus aurantium, foeniculum vulgare and rosmarinus officinalis essential oils on activity of peroxidase enzyme.       me...

background: among most of the hepatic diseases, elevation of alanine amino transferase (alt) level is the hallmark of hepatocyte necrosis. but, no study has been performed in this field in iran. materials and methods: this study is designed to compare the grade, stage, and histological activity index (hai score) of liver pathology between patients with normal serum alt and elevated serum alt. i...

background: glucose-6-phosphate dehydrogenase (g6pd) deficiency is the most common disease of the hexose monophosphate pathway existing in more than 400 million people worldwide. the aim of this study was to identify neonates with g6pd deficiency following national program for screening and education of affected newborns’ parents started since june 2007 in mazandaran, a northern province of ira...

background and objectives: proteases are a group of enzymes that catalyze the degradation of proteins resulting in the pro- duction of their amino acid constituents. they are the most important group of industrial enzymes which account for about 60% of total enzymes in the market and produced mainly by microorganisms. the attempts were made to study the kinetic parameters of protease produced b...

objective(s):diabetes plays an important role in the induction of the liver injury. grape seed proanthocyanidin (gsp) have a wide range of medicinal properties against oxidative stress. in this study we evaluated antioxidant effects of gsp on liver in streptozotocin-induced diabetic rats. materials and methods: thirty male sprague–dawley rats were divided into three groups: control, untreated d...

a pancreatopeptidase (elastase) digest index was devised for a rapid and accurate estimation of protein quality. this index was calculated on the basis of all the amino acids released by an in-vitro elastase digestion, acid hydrolyses of same sample and the residue of enzyme hydrolyzed. the amino acids were determined by thin-layer chromatography. samples used were cooked white kidneybeans, coo...

abstract cyanide is a colorless, harmful, and dangerous substance with a smell similar to bitter almond. cyanide forms a stable compound with iron and magnesium and interferes with cell activity by interfering with respiration, carbon stabilization and nitrate revival. in order to evaluate cyanide metabolism in fuji and abassi mashhad apples, a factorial experiment was conducted as split plot b...
