context prenatal testing aims to identify fetal chromosomal and genetic disorders prior to delivery. current invasive procedures such as amniocentesis and chorionic villus sampling (cvs) pose a risk to mother and fetus and such diagnostic procedures are available only to high-risk pregnancies, which limits aneuploidy detection rate. the identification of cell-free fetal dna (cffdna) in maternal ...

Supplementation of branched chain amino acids, especially leucine, is critical to improve malnutrition by regulating protein synthesis and degradation. Emerging evidence has linked leucine deprivation induced protein breakdown to autophagy. In this study, we aimed to establish a cell-free assay recapitulating leucine-mediated autophagy in vitro and dissect its biochemical requirement. We found ...

objective(s): to explore the correlation between expression patterns and functions of mir-383 and ldha in hepatocellular cancer (hcc). materials and methods: we detected the expression of mir-383 and ldha in 30 hcc tissues and their matched adjacent normal tissues using qrt-pcr. then we performed mtt assay, foci formation assay, transwell migration assay, glucose uptake assay and lactate produc...

Background: Naringenin is a bioactive flavonoid found in grapes and citrus fruits including tangelo, blood orange, lemons, and tangerines. The aims of this study were to investigate the ability of naringenin to scavenge free radicals and determine its ability to protect animals from streptozotocin (STZ) -induced liver damage. Methods: The free radical-scavenging activity of naringenin was ev...

Background and objectives: The aerial parts of Artemisia marschalliana Sprengel as an indigenous species of genus Artemisia in the East Azerbaijan province of Iran, was subjected to phytochemical analysis, as well asanti-proliferative, free-radical-scavenging and anti-malarialactivities. Methods: The chemical composition of the essential oil o...

Ex vivo expansion of human umbilical cord blood cells (HUCBC) is explored by several investigators to enhance the repopulating potential of HUCBC. The proliferation and expansion of human hematopoietic stem cells (HSC) in ex vivo culture was examined with the goal of generating a suitable clinical protocol for expanding HSC for patient transplantation. Using primary human mesenchymal stem ...

The popular screening method for urotensin (UT) receptor antagonists is to measure the intracellular calcium concentration with a calcium-sensitive fluorescent dye. This assay format has an inherent limitation on the problem related to the fluorescence interference as it involves fluorescent dyes. In the present study, a label-free assay for the screening of UT receptor antagonists was develope...

background: t-2 toxin is a mycotoxin of type a trichothecenes produced by several fungal genera such as fusarium species. mycotoxins can affect both cell mediated and humoral immune compartments. objective: the purpose of this study was to investi-gate the effect of t-2 toxin on cytokine production by mouse peritoneal macrophages and lymph node t cells. methods: mouse peritoneal macrophages and...
