This study was planned to determine HIV seroprevalence among pulmonary tuberculosis patients, to characterize the isolated mycobacteria into typical and atypical strains and to evaluate the drug resistant pattern of mycobacterial isolates. The study aims to correlate multidrug resistance (MDR) and HIV seropositivity status in pulmonary tuberculosis patients. During the year 1994-1997, 750 pulmo...

Objective(s): To address the alarming problem of methicillin-resistant Staphylococcus aureus (MRSA), herein, a marine Streptomyces capable of producing an anti-MRSA compound has been studied.Materials and Methods: Strain MN41 was morphologically and physiologically characterized and then, molecularly identified using 16SrRNA analysis. To...

The onset of infections by Leishmania parasites mainly caused by amastigote growth inside the macrophages. One of the important properties of lesion-derived amastigote is thought to be the attachment of various host proteins including immunoglobulins on the surface of amastigote. In this study, the presence of immunoglobulins on the surface of lesion-derived amastigotes was detected by Western ...

Background and Objective: Oxidative stress induced by proinflammatory cytokines such as IL-1β plays a major role in β-cell destruction in diabetes type 1. Salvianolic acid B (Sal B) is a polyphenolic compound with antioxidant and protective effects. Thus, objective of this study was to assess the protection exerted by Sal B on isolated rat islets exposed to IL-1β and to investigate an underlyin...

 Background: Systemic lupus erythematosus (SLE) has various presentations in children. Hematologic abnormalities is common in childhood onset of SLE, however, isolated thrombocytopenia is relatively rare. Thus, we present a child with isolated thrombocytopenia as a rare presentation of SLE. Case presentation: A 12-year-old boy with chief complaints of loss of appetite, weight loss, decrease...

Introduction: Marine actinomycetes have a great potential to produce unique bioactive compounds due to their special adaptation in the harsh ocean environment. The current study aimed to isolate anti-cancer compounds producing actinomycetes from sediments of Harra forests of the Persian Gulf and investigate their potential as anti-breast cancer metabolites. Methods: In the current study, 40 se...

conclusions we found that purified locally isolated soluble crude antigens of the rh strain of t. gondii from the peritoneal cavity of mice may be one of the most promising antigens for detection of human toxoplasmosis in routine screening. results indigenous elisa was used to examine 100 serum samples containing anti-t. gondii igg, with a sensitivity of 98% (commercial kits: 100%). another 100...
