Background Leukocytes linked directly and indirectly to reactive oxygen species (ROS) formation. Although leukocytospermia is defined as the presence of ≥1×106 white blood cells/mL (WBC/mL) in a semen sample, the presence of less than 1×106 WBC/mL (low-level leukocytospermia) still can produce a detectable amount of ROS, impairing sperm function and lowering the chances of pregnancy. Low concen...

1, 4, 5, 6-Tetrahydro-2-methyl-4-pyrimidine carboxylic acid (ectoine) is an excellent osmoprotectant. Ectoine and hydroxyl ectoines are of great significance to the biotechnology industry, thus the detection and isolation of ectoine producing bacteria is of great importance. Hence, this study involved the detection of the ectC gene (encoding ectoin synthase enzyme) using polymerase chain reacti...

ATPase inhibitory factor-1 (IF1) preserves cellular ATP under conditions of respiratory collapse, yet the function IF1 normal respiring is unresolved. We tested hypothesis that promotes mitochondrial dysfunction and pathological cardiomyocyte hypertrophy in context heart failure (HF). Methods results: Cardiac expression was increased mice humans with HF, downstream neurohumoral signaling pathwa...

Cumin, Cuminum cyminum L., is the king of spices with a plethora of natural compounds with pharmacological features. Drought stress is a well-known factor that influences the production of some metabolites. We studied the impact of drought stress on gene expression and metabolite content in flower and leaf tissue organs of two ecotypes, Taybad and Ardakan populations. Plants were imposed into t...

ABSTRACT We analyzed the mechanisms underlying enhanced IgA production in cells of Peyer's patch via membrane vesicles derived from Lactobacillus sakei subsp. NBRC 15893. Depletion CD11c+ suppressed mediated by vesicles. Meanwhile, stimulation bone-marrow–derived dendritic with increased gene expression inducible nitric oxide synthase, retinaldehyde dehydrogenase 2, and several inflammatory cyt...

nitric oxide is a short-lived mediator, which can be induced in a variety of cell types and produces many physiologic and metabolic changes in target cells. it is important in many biological functions and generated from l-arginine by the enzyme nitric oxide synthase. nitric oxide conveys a variety of messages between cells, including signals for vasorelaxation, neurotransmission and cytotoxici...

a rapid isocratic method of high performance liquid chromatography system (hplc) with a glassy carbon working electrode of electrochemical detector is set up for quantitative detection of  trace amount of nitrite ion (no2¯) in aqueous protein containing cell lysate, cell media, plasma, serum, urine and other body fluids. the solid extraction  reversed phase cartridges (sep-pak) are used for dep...

The high lethality in peritonitis and the lack of data on role various NO-synthase isoforms its pathogenesis suggests advisability research to study effects (NOS) inhibitors.
