tropical fasciolosis caused by infection with fasciola gigantica is regarded as one of the most important single helminthes infections of ruminants in asia and africa. fasciolosis diagnosis, due to low sensitivity of coprological diagnostic method has been challenging for a long period. to evaluate the usefulness of elisa for diagnosis of anti – fasciola gigantica antibodies in parasitized shee...
Introduction & Objective: The plasminogen activator inhibitor-1 (PAI-1) is an important regula-tor of fibrinolysis at sites of vascular injury and has been implicated in the pathogenesis of thrombosis at the arterial sites. The aim of this study was to examine the effect one month aerobic exercise and vitamin E consumption on plasminogen activator inhibitor-1. Materials & Methods: In this qua...
Background: Crohn's disease and Ulcerative colitis are known as inflammatory bowel disease with high morbidity which are as a result of increasing immune responses to intestinal microbiota in genetically susceptible individuals. The association of adherent invasive Escherichia coli with Crohn's disease in human has been discussed for decades. The principal aim of this study was to assess the re...
Background: Cystic echinococcosis (CE) is a helminthic disease caused by the larval form of Echinococcus granulosus. In the present study, the B8/2 subunit of antigen B (AgB) of E. granulosus was expressed in E. coli host and then applied in a diagnostic ELISA set up. Methods: The DNA sequence of AgB8/2 subunit from E. granulosus was extracted from the GenBank and codon-optimized. The target s...
Background: The advent of recombinant DNA technology has facilitated heterologous expression of proteins from various sources in different host systems including Escherichia coli. If a plant virus coat protein is expressed in the bacterium it can be used as the antigen for antibody preparation. Such a recombinant antigen preparation can be particularly useful where equipment such as ultracentri...
background : e-cadherin is a trans-membrane glycoprotein that plays a critical role in many aspects of cell adhesion as well as establishment and maintenance of epithelial cell polarity. loss of the adhesive function of e-cadherin seems to promote invasive and metastatic properties of neoplastic cells. objectives: the present study is a retrospective study aiming to evaluate the loss of e-cad...
Excretory/Secretory antigen was prepared by culturing live adult worms of Haemonchus contortus in RPMI 1640 medium at a concentration of 50 worms per mL in a culture-flask at 37 ˚C for 24 hr and the culture supernatant was used as antigen. The E/S antigen was purified by thiol-sepharose affinity chromatography. On western blot analysis, it was demonstrated that thiol-purified antigen showed a s...
Background and purpose: Lactic acid bacteria (LAB) play an important role in human and other organisms life. Some of LABs kill pathogenic and other harmful microorganisms. Enterococcus are, gram-positive, catalase-negative, cocci forming, non-sporogenesis, and facultative anaerobic bacteria. This study was done to identify and isolate possible probiotic bacteria with benefits to human health fr...
The expression of Ia antigen by various murine and human macrophage populations and the ability of prostaglandins of the E series to regulate Ia antigen expression were explored. Monocytes and macrophages from human and murine populations demonstrated a dichotomy in the expression of Ia antigen. Both human monocytes and macrophages expressed elevated levels of Ia antigen compared to their murin...
