genus leishmania is a protozoan parasite that causes different severe diseases. fetal calf serum (fcs) is the major part of the leishmania culture media, for mass cultivation and the most expensive ingredient in these media. in the present work, the efficacy of chicken serum was evaluated in leishmania culture media. the results indicated that, the (10%) chicken serum enriched culture medium su...

Nano-silver (AgNP) has biological properties which are significant for consumer products, food technology, textiles and medical applications (e.g. wound care products, implantable medical devices, in diagnosis, drug delivery, and imaging). For their antibacterial activity, silver nanoparticles are largely used in various commercially available products. Thus, the use of nano-silver is becoming ...

in this paper we introduce the notion of classical quasi-primary submodules that generalizes the concept of classical primary submodules. then, we investigate decomposition and minimal decomposition into classical quasi-primary submodules. in particular, existence and uniqueness of classical quasi-primary decompositions in finitely generated modules over noetherian rings are proved. moreover, w...

Microglia is considered the only cell population of mesodermal origin, which comprises 10% of the cells in brain parenchyma. Recent neural stem cell (NSC) studies demonstrate that the brain has regenerative potential. NSCs do not give rise to microglial cells, however indicating that NSCs alone cannot complete the regenetion of the brain. Although the role of microglia is not fully understood, ...

The aim of the present study was to develop an in vitro system for functional investigation of ovarian follicular cells in Sterlet, Acipenser ruthenus. Oocytes for the primary culture were obtained from the ovaries of a 6 years old Sterlet 729 g in weight and 47 cm in total length. The oocytes were in advanced vitellogenesis stage (PI >10). A part of the ovary (containing about 300 follicles) w...

Glioblastoma multiform (GBM) is the most common and malignant form of glial tumors. GBM microenvironment contains various cell types showing characteristics of activated or dimorphic macrophages/microglia. Some of these cells provide significant help for tumor growth, while others are able to inhibit tumor progression. Microglia play a major role in brain function by monitoring tissue for patho...

Background: Human fibroblasts are the part of the dermis that secrete extracellular matrix for the purpose of tissue repair. Culturing fibroblasts, which leads to formation of a monolayer of these cells, is used for treating various conditions including thermal burns and other skin defects such as diabetic and varicose vein leg ulcers. Therefore, we aimed at developing a fibroblast bank to acco...

In this study we show that patients with primary biliary cirrhosis (PCB) have a marked deficiency in the ability to generate an autologous mixed lymphocyte reaction (AMLR) but have a normal ability to generate an allogeneic mixed lymphocyte reaction (MLR). This deficiency is not due to differences in the time-course of the proliferative response or to an altered response to variable numbers of ...
