Cu-substituted 58S bioactive glasses (0-10%mol CuO) were synthesized by sol-gel method and the effect of copper substitution for calcium on their biodegradability, bone-like apatite formation, cell proliferation, alkaline phosphatase activity of M3T3-E1 osteoblast cells and antibacterial efficiency were investigated. The results of x-ray diffraction (XRD) and Fourier transform infrared spectros...

Stem/progenitor cell based therapeutic approach in our daily routine clinical practice, has been elusive dream in medical sciences and improvement of stem cell homing as one of major challenges in cell therapy programs, has been considered a promising milestone. It has been proved that stem/progenitor cells exhibit a homing response to injured tissues/organs, mediated by interactions of chemoki...

Bcl-2, a well-known anti-apoptotic gene, promotes cell viability without cell proliferation. Expression of the bcl-2 oncogene is reported in certain low grade neoplasms including Basal Cell Carcinomas(BCCs). Bcl-2 expression in BCCs is contradictory, with 67-100% immunopositivity being reported. The purpose of this study was to evaluate bcl-2 expression in the indolent variants of B...

Objective: Silymarin is a herbal extract containing flavonolignans, and it has inhibitory effects against the growth of different cancer cell lines by inducing apoptosis. Toll-like receptors are suggested as a novel and attractive target to treat cancer. The current study aimed at examining the mechanism of silymarin-induced apoptosis in Ramos cells and investigating its effect...

Background & Objective: Type1 diabetes is characterized by autoimmune destruction of pancreatic β cells, leading to reduced insulin secretion. Differentiation of mesenchymal stem cells (MSCs) into β-like cells offers new ways of diabetes treatment. MSCs can be insulated from the human umbilical cord tissue and differentiate into insulin-producing cells. Material & Methods: Human um...

Background: Male infertility refers to the inability of a male to achieve a pregnancy in a fertile female. The root of many causes of infertility is miscommunication between immune and reproductive system. Male reproductive system is very sensitive and vulnerable, infections can hinder maturation and movement of spermatozoa lead to impaired fertility.All species need an immediate reply to the m...
