objective(s): silver nanoparticles (ag-nps) are one of the most widely used nanomaterials recently. despite the wide application of nanomaterials, there is limited information concerning their impact on human health and the environment. this study aimed to find the effects of ag-nps (40 nm) on blood serum, liver and kidney tissues of homing pigeons (columbia livia).materials and methods: columb...

Background: This study was conducted to evaluate the effects of feeding on biochemical parameters in terms metabolic profile female and male lambs Dorper Lacaune breeds at developmental stages from birth. Methods: A total 32 singleton newborn breed (n= 8 for each group; female) were used. The trial continued 5 nutritional periods 21-day after first two weeks (0-14 days) suckling period. determi...

in the present study, changes of values of serum 17ß-estradiol (e2), asparate amino teransferase (ast), alanine amino transferase (alt) and lactate dehydrogenase (ldh) following intraperitoneal (i.p) injection with the aromatase inhibitor (ai) letrozole were investigated in rainbow trout (oncorhynchus mykiss). forty- eight apparently healthy rainbow trout (mean weight of 845 g) divided in four ...

 The purpose of this study was to investigate the therapeutic effects of natural products like propolis on biochemical and hematologic parameters in carp (Cyprinus carpio, Linnaeus 1758) exposed to arsenic. In this study fish were exposed to 0.01 mg/L arsenic and 10 mg/L propolis for seven days. Our results indicated that triglyceride, urea, total cholesterol, cobalt, ALT (alanine amino transfe...

aim :  to evaluate the association of dnmt1 and mgmt amino acid substitution polymorphisms and colorectal cancer in iranian population. background : the mgmt and dnmt1 are two important methyltransferase enzymes. amino acid substitution polymorphisms in mgmt and dnmt1 genes may be associated with the genetic susceptibility to sporadic colorectal cancer. patients and methods : we assessed eight ...

Background: Margarine contain trans fatty acids as major sources of dietary free radicals, and oxidative stress. Effect of oral administration of margarine on hepatic enzyme was investigated in Wistar rats. Methods: Thirty six (36) adult Wistar rats were uniformly divided into three groups of control , margarine 15% and 20%, twelve rats in each groups (6males & 6 females). Margarine was add...

Objective: Diabetes Mellitus (DM) is one of the leading causes of death, illness, and economic loss in the world. The present study was attempted to evaluate extract of Foeniculum vulgare (fennel) on lipid profile, lipid peroxidation and activities of amino transferase enzymes in streptozocin induced diabetic adult male rats. Materials and Methods: The effects of daily oral administration of...
