Introduction: Because radiology technologists are exposed to protracted low-dose ionizing radiation and considering the possible effects of low-dose radiation on blood factors, we aimed to investigate the effects of occupational exposure on blood factors of radiographers working in radiology departments of Khuzestan Province, Iran. Materials and Methods: This case-control study was conducte...
Background: Hematopoietic stem cell transplantation (HSCT) is a therapeutic approach in treatment of hematologic malignancies and incompatibility of bone marrow. Umbilical cord blood (UCB) known as an alternative for hematopoietic stem/ progenitor cells (HPSC) for in allogenic transplantation. The main hindrance in application of HPSC derived from umbilical cord blood is the low volume of colle...
Background: There is evidence that mesangial cell structural changes contribute to the pathogenesis of diabetic nephropathy. To gain better insight into the mechanisms responsible for this issue, present study focused on effect of cord blood mononuclear cells (MNCs) derived CD133 positive cells on mesangial cell structure and function. Materials and Methods: The animals were randomly divided in...
Introduction: Rectal cancer is a heterozygous disease in which cancerous cells grow in the rectum and lower parts of the colon. The primary cause of this cancer is not yet known, but factors such as over age 50, smoking, family history, improper diet or having a history of polyps and inflammatory bowel disease are the major risk factors for developing the rectum cancer. The rec...
Introduction: Considering the development of nanotechnology and extensive use of nano-materials are in different fields of industry, it is necessary to investigate their destructive effects on biological systems. Titanium dioxide(TiO2) is used in the production of different dyes, cosmetics, ceramics, photocatalysts, water and sewage treatment and a lot of other products. In the present study, t...
Efforts have been made to study the behavior of complex materials in micrometer dimensions with various techniques. One of these methods is the use of optical tweezers for biophysical applications. Red blood cells, as the most abundant blood-forming cells, play an important role in the life of living organisms, and their unique mechanical properties are important. In this report, the study of s...
Background: The appendix is considered as part of the gut-associated lymphoid tissue; however, lymphocyte subsets in this tissue are not fully defined. Objective: To investigate and compare the function and phenotype of lymphocyte subsets in peripheral blood and appendix of patients with normal and inflamed appendix tissues. Methods: Peripheral blood samples and appendiceal mononuclear cells we...

کوکسیدیوز بیماری انگلی ناشی از یک انگل تک یاخته ای از جنس ایمریا است (larry et al., 2008)، که با آسیب رساندن به بافت روده، دریافت غذا و جذب مواد غذایی را کاهش داده و همچنین احتمال ابتلا به عفونت های ثانویه را افزایش می دهد (morris et al., 2007; cooper and songer, 2009). این بیماری مهم ترین و متداول ترین بیماری انگلی طیور صنعتی در سراسر جهان بوده که خسارات اقتصادی آن در مزارع پرورش طیور دائمی اس...
Cancer is type of disease caused by irregular, uncontrollable growth of blood cells in bone marrow. The process of generating three main blood cells including pallets, red and white blood cells, is started from a progenitor cell called as blast. Blast generates a considerable number of immature cells which are developed affected by differentiation factors. If any interruption occurs during this...
