background: hypertension is considered an independent risk factor for cardiovascular mortality in diabetic patients. the present study was designed to determine the role of gamma amino butyric acid b (gabab) receptor and l-arginine (l-arg) in gaba-induced vasorelaxation in normal and streptozotocin-induced diabetic rat vessels. methods: diabetes was induced by a single i.p. injection of strepto...

to study the anticoccidial and antioxidant effects of garlic powder (gp) and total sulfur amino acid (tsaa) on growth performance, faecal oocyst output, oxidative stress indicators and antioxidant status markers in broiler chickens, a 2 × 2 × 2 splitplot-factorial arrangement of treatments was used. a total of 480-day-old male broiler chickens were equally assigned to two plots. two hundred for...

in this study, the cdna growth hormone (cgh) of the belugasturgeon (husohuso) and russian sturgeon (acipensergueldenstaedtii) were cloned and sequenced, and phylogenetic relationships were examined using nucleic acid and amino acid sequences. the nucleotide sequence of the beluga gh has an open reading frame of 645 nucleotides encoding a protein 214 amino acid residues. the signal peptide cleav...

abstract           introduction: genetic variations in the gene encoding endothelial nitric oxide synthase (enos) enzyme affect the susceptibility to cardiovascular disease. identification of the way these changes affect enos structure and function in laboratory conditions is difficult and time-consuming. thus, it seems essential to perform bioinformatics studies prior to laboratory studies to ...

Newcastle Disease (ND) is a major viral disease in Indonesia. It is an RNA virus belongs to Paramyxovirinae. It is well known that RNA virus is easily to mutate. In some cases, this mutation could generate virulence alteration. It is noted that mutation of NDV which has avirulent amino acid sequence on the cleavage site, could mutate to be virulent Newcastle Disease Virus (NDV). It is needed to...

In this study, silver nanoparticles were chemically synthesized and deposited on glass substrates using a reducing agent of sucrose, at 50°C. Different characterizations including atomic force microscopy (AFM), field emission scanning electron microscopy (FESEM), and Raman spectroscopy were obtained to study silvery substrates. Then, the silvery substrates were used as the SERS substrates to de...

BACKGROUND: Sustainable agriculture today plays an important role in the utilization of organic matter and biofertilizers to eliminate or reducing chemical fertilizer, promoting fertility and preserving biological activities, enhancing the health of agricultural products and reducing environmental damage. OBJECTIVES: Current research was conducted to asse...

The presented study aimed at investigating the effect of foliar application of amino acids and nano particles and chelated iron on photosynthetic pigments and yield of potato. To this end a factorial experiment was carried out in the form of randomized complete block design with three replications in 2013, in the Research Field of Natural Resources Institute in Damavand, Iran. The first factor ...
