Objective: The mean platelet volume lymphocyte ratio (MPVLR) and (MPVPR) reflect inflammation more effectively strongly than MPV, lymphocyte, platelet, neutrophil counts separately, we aimed to evaluate the importance of MPVLR MPVPR in COVID-19 patients. Material Methods: Patients with were divided into two groups based on whether their RT-PCR test resulted a positive or negative result. MPVLR,...

Lymphocyte development is initiated from hematopoietic stem cells and can be divided into multiple phenotypically distinct stages. Transcription factors play important roles in programming the developmental process of lymphocytes. Recent studies have identified key roles of several orphan nuclear receptors in T lymphocyte development. The orphan nuclear receptor RORgamma has been shown to promo...

In vitro lymphocyte responses to Pseudomonas aeruginosa have been found to be impaired in cystic fibrosis patients with advanced clinical disease. The responses to Klebsiella pneumoniae, Serratia marcescens, and Proteus mirabilis were studied in a similar group of cystic fibrosis patients and normal individuals. Cystic fibrosis patients found to be unresponsive to pseudomonas were also unrespon...

Much was accomplished in the last decade in understanding how the adaptive immune system evolved to combat pathogens. Essential features of antigen presentation and T lymphocyte recognition were deciphered, setting the stage for further studies that elucidated basic elements of lymphocyte differentiation (including positive and negative selection during lymphocyte ontogeny) and the major intera...

The effects of organic and inorganic sources and concentration (0 and 0.3 mg per kg of diet) of Selenium (Se) on growth performance, blood biochemical and immune system were evaluated in broiler chickens. Chickens were fed corn-soy-based diets formulated to 8 dietary treatments containing no added Se (negative control), negative control plus yeast (positive control), and 6 diets had 0.3 mg/kg o...
