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...

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...

cryptococcus neoformans is the most incriminated fungal pathogen causing meningitis in acquired immune deficiency syndrome (aids) patients, and is known to constitute a major cause of deaths in aids patients. this study aimed to determine the sero-prevalence and effect of cd4 count on seropositivity for cryptococcus neoformans antigen (crag) in antiretroviral- naïve (art-naïve) aids patients. t...

background and objectives: uterine smooth muscle tumors are the most common human neoplasm .they are divided clinically as benign and malignant but there is  another group of  lesions which is difficult to place in these two categories ,so-called smooth  muscle tumors of uncertain malignant potential (stump) and differentiation  of these tumors on the basis of h&e staining is impossible . t...

conclusions results showed that whereas knowledge by itself cannot guarantee men’s participation in prostate cancer screenings, perceived barriers can play an important role in discouraging men from cancer screening participation. therefore, designing programs to address these barriers is very important. results the most common barriers to screening for prostate cancer were a lack of knowledge ...
