The major histocompatibility complex is directly involved in the immune response, and thus genes coding for its proteins are useful markers study of genetic diversity, susceptibility to disease (autoimmunity infections), transplant medicine, pharmacogenetics, among others. polymorphism system also allows researchers use it as a proxy population genetics analysis, such admixture structure. In or...

Evaluation of a new generation of sodium slides and reference fluid for use with the Kodak Ektachem 400 Analyzer demonstrated improved performance in generation 04 over the previous generation 03 slide for sodium determinations. A decrease in between-replicate imprecision and a correction of the "serum" assigned values of the calibrators used to calibrate the slide used with the reference fluid...

OBJECTIVE Type 1 diabetes mellitus (T1D) is an autoimmune and multifactorial disorder. Subsequent analysis on human leukocyte antigen ( HLA) region shows that HLA-DRB1 and -DQB1 genes have the strongest association with T1D. In this study, for the first time, we investigated the influence of gender on the HLA-DRB1 and -DQB1 association with type 1 diabetes mellitus in Iranian patients in order ...

The purpose of this 6-month randomized, placebo-controlled trial was to determine the effect of season-long (September-March) vitamin D supplementation on changes in vitamin D status, which is measured as 25(OH) D, body composition, inflammation, and frequency of illness and injury. Forty-five male and female athletes were randomized to 4,000 IU vitamin D (n = 23) or placebo (n = 22). Bone turn...

In vitro evidence presently favors a direct osteolytic effect of biologically active vitamin D metabolites. Studies were designed to evaluate the effect of 25-hydroxycholecalciferol (25OHD3) on bone collagen and mineral maturation in vivo and its dependence on parathyroid hormone (PTH). After treatment of sham-operated control and parathyroidectomized (PTX) mature rats with either 25OHD3 or an ...

Semi-arid soils cover a significant area of Earth's land surface and typically contain large amounts of inorganic C. Determining the effects of biochar additions on CO2 emissions from semi-arid soils is therefore essential for evaluating the potential of biochar as a climate change mitigation strategy. Here, we measured the CO2 that evolved from semi-arid calcareous soils amended with biochar a...

Dengue is one of the most globally serious vector-borne infectious diseases in tropical and subtropical areas for which there are currently no effective vaccines. The most highly conserved flavivirus protein, NS5, is an indispensable target of CD8+ T-cells, making it an ideal vaccine design target. Using the Immune Epitope Database (IEDB), CD8+ T-cell epitopes of the dengue virus (DENV) NS5 pro...
