Evaluation of organic carbon, elemental carbon, and water soluble organic carbon concentration in PM2.5 in the ambient air of Sina Hospital district, Tehran, Iran

In the present study, carbon species including organic carbon (OC), elemental carbon (EC), and water-soluble organic carbon (WSOC) concentration in PM2.5 were assessed at an urban site of Tehran, Iran during March to June 2014. The PM2.5 samples were collected using an frmOMNITM Ambient Air Sampler. Thermal gravimetric analysis (TGA) was used to analyze OC and EC. The results showed that PM2.5 ...

بررسی تأثیر سرم موش حامله بر روی سلولهای دندریتیک در القاء تحریک لنفوسیت‌های T و تولید سیتوکین‌های IL-10 و IFN-γ Dendritic Cells and Antigen Specific T Cell Responses: Effect of Pregnant Mouse Serum

    Background & Aim: Tolerance to the semi-allogenic fetal graft by the maternal immune system is a medical enigma that has stimulated investigations for a half of century. Several hypotheses have been proposed to explain the tolerance of mother to the fetus. The successful pregnancy is proposed and proved by many scientists to be a Th2 dominant phenomenon. This hypothesis is proved in most as...

Evaluation of effective factors in the optimization of immunization to achieve antibodies against RhD antigen in culture medium

Abstract Background and Objectives Antibody against RhD antigen is important in blood transfusion and clinical medicine. Therefore, in this study, the effective factors in the optimization of in vitro immunization to achieve immunized lymphocytes that produce antibodies were evaluated to obtain antibodies against RhD antigen in the culture medium.

Comparision of the effects of Leishmania Soluble Antigen (LSA) and Lipopolysaccharide (LPS) on C57BL/6 Mice Macrophage Function

Background: Macrophages activation is the important anti-leishmania immune response. Different signals could affect macrophages development and functional activation. Objectives: In the present study, we compared the effect of Leishmania Soluble Antigen (LSA)and Lipopolysaccharide (LPS) on peritoneal macrophage responses. Appropriate activation of macrophages depends on thesignals they receive ...
