This study is part of the Follow up Restoration Program of animal communities that colonize the Guadiamar River Basin. In 1998, the area was affected by a release of toxic sludge after the retention walls of the Aznalcóllar Mines (southern Iberian Peninsula) broke. The main objective of this study was to assess the current state of the population of Tenebrionidae, one of the most representative...

background: in spite of available, and sensitive screening assay for detection of hepatitis b virus surface antigen (hbsag), occasional cases of post-transfusion hepatitis b virus infection are still observed. the aim of the present study was to assess the prevalence of positive anti hepatitis b core (anti-hbc) and presence of hbv-dna in serum sample of healthy blood donors negative for both hb...

Background: The outcome of Hepatitis B virus (HBV) infection is chronic or resolved HBV infection. Over the time, the levels of HBsAg or Anti-HBs declined and were not detectable in their sera and was named as isolated anti-HBc. The purpose of this study was to assess the prevalence of isolated anti-HBc in previously HBV infected individuals.Methods: From April 2000 to September 2008, the resul...

The enterotoxins (ETs) of Clostridium perfringens isolated from enterotoxemic or diarrheic alpacas, pigs, calves, dogs, and horses were obtained from sporulated cell extracts. The ETs from alpaca, pig, and calf isolates were chromatographed on Sephadex G-lOO. Monoclonal antibodies (MAbs) against ETs derived from alpaca, pig, and calf C. perfringens isolates were produced. The MAbs were used...

1. the most important challenge in diagnosis of celiac disease is not-performing the diagnostic tests in suspected persons. because of multi-organ damage and multiple manifestations of disease, diagnosis of celiac disease may be delayed. it seems general physicians should be aware about uncommon presentations of disease and indications of celiac tests. 2. the second most important challenge is ...

the most important progress in the field of retinal diseases during recent years might be the introduction of pharmacotherapy. age-related macular degeneration for instance was an irreversible disease leading to permanent anatomical and functional changes in the macula up to the previous decade; however, the use of anti-vascular endothelial growth factor agents (anti-vegfs) not only stops the p...
