AIM A digital PCR approach has recently been suggested to detect greater amounts of cell-free fetal DNA in maternal plasma than conventional real-time quantitative PCR (qPCR). Because the digital qPCR approach uses shorter PCR amplicons than the real-time qPCR assay, we investigated whether a real-time qPCR assay appropriately modified for such short amplicons would improve the detection of cel...

objective: grape virus diseases are a serious problem in iran. leaves and fruits of grape have been used for different purposes like cooking in iran. the present investigation was carried out to study on the cytotoxic-activities of extracts of fruits and leaves of vitis vinifera from both virus-free and virus-infected grape cultivars against breast cancer cell line (mda-mb-231) and human embryo...

Abstract Curcumin, which is derived from the turmeric rhizomes (curcuma longa) as a natural polyphenol, is a substantially lipophilic molecule. This commonly used substance is employed as a spice and coloring agent in food and contains potent antioxidant, as well as anti-inflammatory, and anti-proliferative tumor activities. The developed nanomicelle formulations of curcumin are used to ...

BACKGROUND Receptor occupancy (RO) assays provide a means to measure the direct interaction of therapeutics with their cell surface targets. Free receptor assays quantify cell-surface receptors not bound by a therapeutic while total receptor assays quantify the amount of target on the cell surface. METHODS We developed both a flow cytometry-based free RO assay to detect free surface CXCR4, an...

in the present study, free-radical-scavenging and antioxidant activities of angipars™, an herbal extract which has been registered as a therapeutic drug for diabetic foot ulcer, were examined. we investigated the protective effect of angipars™ on cytotoxicity produced by exposure to h2o2 (300 µm) in hepg2 and a549 cell lines, using mtt assay, glutathione (gsh) content analysis, and lipid peroxi...

Objective(s): Cord blood (CB) is known as a valuable source of hematopoietic stem cells (HSC). Identifying strategies that enhance expansion and maintain engraftment and homing capacity of HSCs can improve transplant efficiency. In this study, we examined different culture conditions on ex vivo expansion and homing capacity of CB-HSCs. Materials and Methods: In this study, 4-5 different units o...

Introduction: Free radicals are molecules that have unpaired electrons in their last layer. The excessive production of free radicals causes oxidative stress. Oxidative stress thus adversely alters proteins, DNA and oxidation of the membrane phospholipids. Methods: The cytotoxic effects of zinc oxide nanoparticle were evaluated using MTT (3- (4-5-dimethylthiazol-2-yl) -2,5-difenyltetrazolium br...
