background: the sry gene (sry) provides instructions for making a transcription factor called the sex-determining region y protein. the sex-determining region y protein causes a fetus to develop as a male. in this study, sry of 15 spices included of human, chimpanzee, dog, pig, rat, cattle, buffalo, goat, sheep, horse, zebra, frog, urial, dolphin and killer whale were used for determine of bioi...

the  non-classical mhc  class-i mainly involves in the  regulation of  innate  immune responses where hla-e  plays a significant role in the cell identification by natural killer cells. hla-e is a main regulatory ligand for natural killer cells and given the importance of these effector cells in hematopoietic stem cell transplantation, we investigated the effect of hla-e polymorphisms on post-h...

Natural killer cells are key cells of the innate immune system. Natural killer cell receptor repertoires are diversified by a stochastic expression of killer-cell-immunoglobulin-like receptors and lectin-like receptors such as NKG2 receptors. All individuals harbor a subset of natural killer cells expressing NKG2A, the inhibitory checkpoint receptor for HLA-E. Most neoplastic and normal hematop...

Oxidative stress after major surgeries is associated with the development of poor clinical outcomes including delayed wound healing and increase in Pediatric Intensive Care Unit (PICU) length of stay. Due to the growth and development phase in childhood, the change in the levels of oxidative stress and inflammation is of high importance in these patients. Notably, the acute metabolic stress whi...

The positive semidefinite (psd) rank of a nonnegative real matrix M is the smallest integer k for which it is possible to find psd matrices Ai assigned to the rows of M and Bj assigned to the columns of M , of size k ˆ k, such that pi, jq-entry of M is the inner product of Ai and Bj . This is an example of a cone rank of a nonnegative matrix similar to nonnegative rank, and was introduced for s...

Robots M. A. El-Dosuky 1, M. Z. Rashad 1, T. T. Hamza 1, and A.H. EL-Bassiouny 2 1 Department of Computer Sciences, Faculty of Computers and Information sciences, Mansoura University, Egypt 2 Department of Mathematics, Faculty of Sciences, Mansoura University, Egypt Abstract For a mobile robot to be truly autonomous, it must solve the simultaneous localization and mapping (SLAM) problem. We dev...

Killer plasmids pGKL1 and pGKL2 of double-stranded linear DNAs were transferred from Kluyveromyces lactis to strains of Kluyveromyces fragilis and Candida pseudotropicalis. The resultant killer strains produced 17-fold and 6-fold larger amounts of killer toxin than K. lactis did, respectively. The killer toxin produced by each species appeared to be a glycoprotein.

The killing activity of natural killer cells is largely regulated by the binding of class I human leukocyte antigen cognate ligands to killer cell immunoglobulin - like receptor proteins. The killer cell immunoglobulin - like receptor gene - complex contains genes that activate and others that inhibit the killing state of natural killer cells depending on the binding of specific human leukocyte...
