a new strategy for construction of synthetic gene encoding human basic fibroblast growth factor comprising dna annealing-ligation and augmentation by polymerase chain reaction was introduced. the sequence of the gene and corresponding amino acid chain were modified in order to increase stability of the protein. first, 300 bp and 160 bp fragments of the gene were assembled from 18 oligonucleotid...
we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
. the results of multiple qtl mapping design in recent years indicated quantitative trait loci for milk fat percentage and milk yield traits identified in bta14. dgat1 gene coding diacylglycerol-acyltransferase enzyme, has a main role in the triglyceride synthesis and finally fat milk synthesis. a transition mutation in this gene results substitution of guanine by adenine in the gene causing su...
Background and Objectives: Skeletal muscle mass depends on the balance between synthesis and degradation of muscle protein, which changes with aging and disease. The aim of the present reserch was to examine the effects of two exercise training protocols on alterations of some genes involved in pathways of protein synthesis and degradation in order to achieve a more effective training program i...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
Background: Skeletal muscle mass, which is regulated by a balance between muscle protein synthesis and degradation, is an important factor for movement to meet everyday needs, especially in pathological conditions and aging. The purpose of the present investigation was to compare the alterations of the gene expression involved in muscle protein synthesis and degradation signaling pathways induc...
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
