Background and objectives: Beside its nutritional role, caper (Capparis spinosa) has long been used as an analgesic, anti-inflammatory, anti-diabetic and anti-cancer remedy. In the present study, we tested whether this plant can make effective changes in Sirt3 and mitochondrial function in colorectal carcinoma cell line since mitochondrial dysfunction has long been imp...
Prostate-specific membrane antigen (PSMA) is a type II transmembrane protein, which is anchored in the cell membrane of prostate epithelial cells. It is highly expressed on prostate epithelial cells and strongly up-regulated in prostate cancer. Although, 177Lu-PSMA has been recently introduced for radionuclide therapy of metastatic castration-resistant prostate cancer (mCRPC) with co...
Abstract It has become increasingly evident that even though B cells respond to both soluble and membrane-presented antigens in vitro, the primary mode of antigen recognition vivo appears be on surfaces antigen-presenting cells. To determine how sense an is membrane associated, we investigated role Piezo1 mechanosensing cation channel human B-cell activation. We discovered flux calcium when sim...
Abstract In these notes, we have considered models of electrophysiology across several scales. The first was the membrane model. It assumes that action potential is similar whole cell membrane, and model represents as a function time alone. No spatial variable involved in pure models, so length scale does not make sense.
The aim of this study was to compare invasive and non-invasive strains of Shigella flexneri isolated from Tehran by a 120 kDa protein band by SDS-PAGE, electron microscopy of cell culture and Congo red dye methods. Methods: S. flexneri strains were isolated by standard bacterial methods from fecal specimens of children attending to the 3 children’s hospitals. Phenotype analysis for screening v...
Numerical simulations are used to compare the impact of internal fluid viscosity and membrane on an isolated tank-treading red blood cell. Both decrease frequency, with moderate changes in deformation inclination However, it is shown that frequencies from existing experiments only retrieved if accounted for, apparent shear-thinning membrane.
background & aim:combretaceae family is known for efficacy in the management of sickle cell disorder (scd). based on the earlier reports of anti-sickling property of terminalia genus the study investigates in vitro antisickling properties of terminalia arjuna and terminalia bellirica. experimental: anti-sickling assay of methanolic and aqueous extract of t. arjuna and t. bellirica on ...
امروزه با توسعه روز افزون تکنولوژی mems و کاربردهای گسترده آن در مهندسی پزشکی می توان قطعاتی را طراحی نمود که قابل کاشت (implantable ) در داخل بدن باشد. اندازه گیری مقدار قند خون یکی از زمینه هایی می باشد که با توسعه تکنولوژی memsمورد توجه بوده است. در بیماران دیابتی نوع دوم، میزان قند خون بالا می باشد و از آنجایی که با افزایش قند خون احتمال بیهوشی نیز بالا می رود، لذا اندازه گیری قند خون بصورت...
Background and Objective: Though amniotic membrane has recently been introduced as a natural tissue with anti-cancer properties, there are inadequate studies about involved mechanisms. In this study, the effect of amniotic membrane culture supernatant on viability of cancer cells via applying different doses was evaluated. Apoptosis as a possible mechanism of inducing cancer cell death by amnio...
Abstract The effects of wheat gluten hydrolysates (WGH) and their ethanol elution fractions obtained on XAD-16 resin physiological activity fermentation performance brewer’s yeast during very-high-gravity (VHG) worts were investigated. results showed that the addition WGH in VHG significantly enhanced biomass viability, further increased fermentability, yield productivity yeast. Supplementation...
