Background: Hydatidosis is one of the cosmopolitan parasitic zoonoses caused by the larval stage of Echinococcus granulosus. Diagnosis of hydatidosis is still an unresolved problem. Serological tests using crude antigens for diagnosis of E. granulosus are sensi-tive, however their specificity are not satisfactory. Therefore, WHO recommended spe-cific serological methods using specific antigens,...
Background & Aim: Fascioliasis as a zoonosis is one of the important parasitic diseases which is caused when fasciola species enter the host’s body. Approximately 2.4 million people throughout the world are infected with this parasite and 180 million people are vulnerable to it. On time diagnosis and rapid treatment of the disease can substantially prevent the harmful effects of the infecti...
background: prostate cancer is the most common malignancy among the male population in the united states and the 3rd most common non-skin cancer among men in iran. its prevalence has shown a rising trend in recent decades. the aim of this study was to report the epidemiological features of prostate cancer in patients referred for prostate biopsy in the south of iran and to evaluate the accuracy...
background helicobacter pylori (h. pylori) infection is common among humans and plays a major role in the etiology of peptic ulcer disease with significant morbidity in patients with hiv-1 on antiretroviral therapy. there are conflicting prevalence patterns of h. pylori in hiv-1 infected patients using various methods of detection. the noninvasive technique used for detection of h. pylori infec...
many studies have shown that cytotoxic t lymphocyte antigen-4 (ctla-4) gene variants are associated with several autoimmune diseases particularly type 1 diabetes. due to the lack of consistent data for this association with type 2 diabetes (t2d), this study explored the possible influence of ctla-4 gene polymorphisms at -1722 (t/c), -318 (c/t), and +49 (g/a) positions for susceptibility to t2d ...
a random 12 mers phage library was used to screen a pool of immunoglo¬bulin fractions obtained from vitiligo patients. subsequent to panning experiments, a panel of affinity selected phage from vitiligo patients were obtained. this panel was tested using an elis a for their reactivity with pooled sera from patients and normal controls. among the 16 randomly selected clones, two of clones showed...
background: prostate specific antigen (psa) is a protein currently used in vconjunction with the digital rectal examination to detect and guide management of prostate cancer. there are several causes of increase in serum psa including urological manipulations, medications, prostatic diseases, prostate cancer, prostate inflammation or infection, etc. some studies had reported cystoscopy to cause...
mesenchymal stem cells can be obtained from deferent tissues like adipose tissue, umbilical cord, placenta, skin, bone marrow, etc. these cells have regulatory effects on all types of immune cells such as dendritic cell, natural killers and lymphocytes. mesenchymal stem cells induce inhibitory phenotypes of antigen presenting cells (apcs) following their activity. they also change t cells pheno...
background: prostate specific antigen (psa) is an important laboratory marker for diagnosis of prostatic cancer. thus, development of diagnostic tools specific for psa plays an important role in screening, monitoring and early diagnosis of prostate cancer. in this paper, the production and characterization of a panel of murine monoclonal antibodies (mabs) against psa have been presented. metho...
