oak trees cover a wide range of forests in iran and most of them are located in kohgiloye and boyer-ahmad province (k.b). the high tannin is one of the anti-nutritional characteristics of acorn for domestic animal. wide range of gut microorganisms could tolerate tannin and reduce it by producing tannase enzyme. this study was carried out to isolate and identify the tannin resistance bacteria (t...

α-galycoceramide (α-galcer) or the common name of krn7000 is an α-gelasphin derivative. the α-galcer structure consists of a galactose combined with a ceramide in an α-configuration. social isolation (si) has been linked with enhanced inflammation, through modifications in transcriptional pathways linked with glucocorticoid, to stress. our hypothesis is to investigate mediatory role of glucocor...

mitochondria play key roles in many cell functions including energy production, fatty acid metabolism, pyrimidine biosynthesis, calcium homeostasis, and aging. they also regulate crucial signaling cascades such as apoptosis and oxidative stress. the proteome is often used to investigate the functional correlations on protein levels. based upon the human, genome there is estimated 2000 to 2500 a...

background: campylobacter jejune and c. coli are recognized as the most common bacteriological causes of gastroenteritis in humans. in this study identification of campylobacter jejuni and campylobacter coli from samples using pcr was explored. methods: detection was performed using diarrheal samples collected 8 from 117 children. the genomic dna of samples was extracted by phenol-chloroform me...

background: the aim of the study was to provide a point of reference to study the neospora caninum infections in china. methods: genome dna was extracted from the brains of aborted fetuses and specific pcr was performed with n. caninum nc5-targeted specific primers. fetal bovine brain tissues were homogenized and continuously cultured in vero cells with double antibodies. the medium was replace...

Process and power plant control, along with fault detection/isolation are being addressed by significant on-going research with many theoretical developments focused on improvements for all of these major industrial applications. This report provides an overview of the current key problems, recent accomplishments and trends, as well as a forecast of anticipated developments within this very imp...

to increase the safety of structures against strong ground motions and their life due to environmental issues on the earth and saving in terms of materials, it is necessary to expand and upgrade seismic resistant systems. however, more cost-effective systems which have sufficient influence on the seismic performance of structures and also more compatibility with the regional conditions, will be...

introduction: scorpion venoms contain a variety of peptides, toxic to mammals، insects and crustaceans and are the main factors in scorpion venom toxicity (their amount being 1-3% of total venom). most of the scorpion toxins have been isolated from the venoms of scorpions in the buthidae family. the scorpion buthotus schach of this family is widely found in the western regions of iran, but no p...

to study the existence of clostridium septicum as probable agent associated with currently occurrence of black quarter in urmia area, sheep-dung samples were collected. the bacteriological examinations on suspicious gram positive anaerobic spore-bearing bacilli which are in clostridia genus include isolation and biochemical identification were performed. the results showed 28 different types of...
