abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
The diagnostic ability of antigen-capture enzyme-linked immunosorbent assays (AC-ELISA) and immunohistochemistry using two enzymes labels, alkaline phosphatase (AP) and peroxidase (P), to detect bovine viral diarrhea (BVD) persistent infection (PI) was assessed using serum and ear notch biopsy pairs (n= 469) collected from 12 Holstein dairy herds located in Charlottetown, Canada. The sampled an...
Toxoplasmosis is one of the most common parasitic infection in human and other warm-blooded animals. Serological methods are reliable techniques actually used for diagnosis of toxoplasmosis. Comparison of sensitivity of ELISA and DIG-ELISA for diagnosis of human toxoplasmosis was the main objective of the present work. ...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
abstract english language learning in iran has become significant in recent years, and english has been included in the curriculum of iranian schools and universities, and considerable attention has been paid to this language in our society. nevertheless, teaching and learning english in iranian schools has not been able to satisfy the specified goals, so different efl institutes have been est...
background: the present article focuses on the design and development of a highly sensitive and convenient approach for rapid detection of animal species and cross contaminations quickly during cell cultures as most important document for manufacturing working cell bank system. this test is one of the four most important documents during implementing the banking system. by using this modified t...
In this study, we reported the isolation, identification, and molecular characteristics of nine BVDV strains that were isolated from serum persistently infected cattle. The new designated as TJ2101, TJ2102, TJ2103, TJ2104, TJ2105, TJ2106, TJ2107, TJ2108 TJ2109. TJ2102 TJ2104 found to be cytopathic BVDV, other non-cytopathic BVDV. An alignment phylogenetic analysis showed isolates share 92.2–96....
the purpose of this study was to investigate the relationship between teachers’ class management practices with students’ self- regulated learning and academic self-efficacy. in this study relating to the management class, three dimensions, (training management, people management and behavior management) and three style (interventionist, interactionist and non-interventionist) was considered. r...
one of the most important aspects in recombinant biologic production, based on gmp rules, is the accuracy of final product quality control, especially assessment of host cell macromolecules contamination rate in final product. the purification requirement can be eliminated when the yeast cell containing the recombinant protein is used as a host cell. it is possibile that the final product conta...
Background and Purpose: Many studies report that Toxoplasma gondii excreted / secreted antigens (E/SA) appear to be a suitable marker for toxoplasmosis serodiagnosis. Most of these studies have used E/SA, obtained from supernatant of Toxoplasma cell culture, or by incubating tachyzoites in cell free media (RPMI-1640). The present study for the detection of Toxoplasma IgG in human serum was ev...
