aim : in this paper effect of combinational usage of calprotectin and etoposide on ags cell line is studied. background : application of combined toxic agents such as etoposide and cicplatin are commonly used for chemotherapy purposes. as a matter of fact, calprotectin and etoposide were both applied on human gastric adenocarcinoma cell line (ags) as antitumor agents. both calprotectin and etop...

back ground: candida albicans is a member of the normal human microflora. c. albicans cell wall is composed of several protein and carbohydrate components which have been shown to play a crucial role in c. albicans interaction with the host immune system. major components of c. albican cell wall are carbohydrates such as mannans, β glucans and chitins, and proteins that partially modulate the h...

the aim of this study was to investigate the association of bovine leukocyte antigen-drb3 alleles with peripheral blood mononuclear cell (pbmc) proliferation in response to staphylococcus aureus. the animals included in this study (n=347) were approximately of same age and comprised of f2 holstein-friesian ´ charolais (n = 155), holstein-friesian backcross (f0 holstein-friesian dams crossed wit...

Objective(s) Mesenchymal stem cells (MSCs) from large animals as goat which is genetically more closely related to human have rarely been gained attentions. The present study tried to isolate and characterize MSCs from goat bone marrow. Materials and Methods Fibroblastic cells appeared in goat marrow cell culture were expanded through several subcultures. Passaged-3 cells were then different...

aerial parts of salvia mirzayanii was extracted with methanol. methanol extract was suspended in water and defatted with petroleum ether. the defatted part was then partitioned between ethyl acetate and water. the ethyl acetate partition was chromatographed on a silica gel column to afford several fractions. lymphocyte proliferation inhibitory assay of the resulted fractions was compared in vit...

abstract due to their mulitpotency, mesenchymal stem cells (mscs), have the ability to proliferate and differentiate into multiple mesodermal tissues. the aim of this study was to isolate mscs from human umbilical cord (hucmscs) to determine their osteogenic potential on nanofibrous scaffolds. to this end, poly (l-lactic acid) (plla)/nano hydroxyapatite (ha) composite nanofibrous scaffolds were...

background: one area of nanoscience deals with nanoscopic interactions between nanostructured materials and biological systems. to elucidate the effects of the substrate surface morphology and viscoelasticity on cell proliferation, fractal analysis was performed on endothelial cells cultured on nanocomposite samples based on silicone rubber (sr) and various concentrations of organomodified nano...

the use of low level laser to reduce pain, inflammation and edema, to promote wound, deeper tissues and nerves healing, and to prevent tissue damage has been known for almost forty years since the invention of lasers. this review will cover some of the proposed cellular mechanisms responsible for the effect of visible light on mammalian cells, including cytochrome c oxidase (with absorption pea...

micrornas are 19-22 nucleotide rnas involved in such important processes as development, proliferation, differentiation and apoptosis. different mirnas are uniquely expressed in lymphoid t cells, and play a role indevelopment and differentiation of various subtypes by targeting their target genes. recent studies have shown that aberrant mirna expression may be involved in t cell leukemogenesis ...
