The success of the Human Genome Project (HGP) has provided a blueprint for the approximately 20,000 gene-encoded proteins potentially active in all of the hundreds of cell types that make up the human body. Yet we still have limited knowledge about a majority of the gene-encoded proteins which are the “building blocks of life” and “cellular machinery”. It is estimated that for nearly half of th...
abstract the third millennium has started, but the world is facing with serious challenges in achieving international security and peace. various human rights violations have lead the states to find means to protect human rights. also article 55 of the united nations charter introduces the respect to human rights and fundamental freedom as the most suitable ways to realize peace and security. ...
The Human Genome Project has generated a blueprint for the approximately 20,300 gene-encoded proteins potentially active in any of 230 cell types that make up the human body (human proteome). However, based on the UniProtKB/Swiss-Prot database content, about 6000 of at the protein level; for many others, there is very little information related to protein function, abundance, subcellular locali...

background: some evidences showed that the secretion of uterine tube vagina and follicular fluid (ff) affects x and y-chromosome populations. sperm selection with x or y chromosome can added to oocyte for gender desired. the isolation of x y sperm have done and all efforts in this field are done to make culture media similar to in vivo condition. the objective of this study was to find if the f...
introduction natural and artificial radionuclides are the main sources of human radiation exposure, which enter the food chain from the environment. radionuclides can affect human health by transferring from soil to plants and entering the human body. in this research study, we aimed to determine the activity concentrations of radionuclides and calculate the average annual committed effective d...
Introduction Natural and artificial radionuclides are the main sources of human radiation exposure, which enter the food chain from the environment. Radionuclides can affect human health by transferring from soil to plants and entering the human body. In this research study, we aimed to determine the activity concentrations of radionuclides and calculate the average annual committed effective d...
Background and Aim: Yersinia enterocolitica is a Gram-negative bacterium which its strains are involved in human diseases. To differentiate among pathogenic and non-pathogenic types, tests such as Congo Red absorption, Crystal Violet, and Calcium Dependency test are used. These tests are based on existence of 70-75 kb plasmids and sometimes, with respect to plasmids instability, we will face fa...
Recombinant human interferon-y (Hu-IFN-y) produced by Chinese-hamster ovary (CHO) cells was analysed by immunoprecipitation and SDS/PAGE. Up to twelve molecular-mass variants were secreted by this cell line. Three variants were recovered after enzymic removal of all N-linked oligosaccharides or when glycosylation was inhibited by tunicamycin. The presence of three polypeptide forms rather than ...
Despite its central role in sex determination, genetic analysis of the Y chromosome has been slow. This poor progress has been due to the paucity of available genetic markers. Whereas the X chromosome is known to include at least 100 functional genetic loci, only three or four loci have been ascribed to the Y chromosome and even the existence of several of these loci is controversial. Other fac...
