conclusions some results of the correlation coefficients are not the same with visualization. the reason may be due to the small number of data. materials and methods in the foundation-application study, we constructed two-way gene networks using nonparametric methods, such as spearman’s rank correlation coefficient and blomqvist’s measure, and compared them with pearson’s correlation coefficie...
background: formation of secondary structure such as dna hairpins or loops may influence molecular genetics methods and pcr based approaches necessary for genetic engineering, in addition to gene regulation. materials and methods: a polymerase chain reaction with splice overlap extension (soe-pcr) was used to create fully synthetic 1f5 chimeric anti-cd20 heavy- and light-chain genes. the chimer...
the tlr4 gene structure as the main receptor for lipopolysaccharide recognition of gram-negative bacteria was investigated in two strains of iranian commercial arian line and west azerbaijan native chicks and its expression was studied in some major organs. blood samples of the 120 birds were taken and total dnas extracted. then, the target gene was sequenced using four pairs of primers on four...
Gene families are considered as groups of homologous genes which they share very similar sequences and they may have identical functions. Members of gene families may be found in tandem repeats or interspersed through the genome. These sequences are copies of the ancestral genes which have underwent changes. The multiple copies of each gene in a family were constructed based on gene duplicati...
in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
Aquatic organisms present, not only simple sources of accumulated metal, but can interact with metals, altering their toxicity. Due to exposition of biosphere with metals, organisms have developed various defense mechanisms to protect themselves against adverse effects of these ions and their compounds. Metallothionein (MT) is one of that which represents a critical mechanism for detoxification...
Salinity as one of the most important stresses disturbs favorable growth conditions of the plants leading to several metabolic disorders such as reactive oxygen species (ROS). Monodehydroascorbate reductase (MDHAR) with FAD (Flavin adenine dinucleotide) co-factor is one of the key enzymes in Glutathione-ascorbate pathway which reduces monodehydroascorbate (MDHA) radicals. In this study MDHAR ge...
abstract: the present thesis includes ; one preface and 11speeches , that each speech considered in different researches . the prefact part , studied grammer back ground , the first speech considered a brief description about grammatical credits . the second speech considered the different typs of sentences , from structure and meaning points of view . the third speech considered the verb es...
Background and purpose: Polymerase chain reaction (PÇR) is a rather quick and accurate method employed for gene detection and isolation. Primer designing is an important issue in this technique and plays a critical role in considering both the genome properties and cloning of the isolated genes. Streptomycin antibiotic is produced by Streptomyces griseus using str gene cluster with more than 25...
objectives the overall goal of this study was to carry out a set of comparative analyses of arsr gene in plasmid r773 and bacterial chromosome from escherichia coli bl-21(de3). methods pdb and ncbi databases and chimera, mega4, clc main workbench software and 3d-jigsaw and embl-ebi servers were applied to perform this study. by using these software and servers, multiple analyses including deter...
