Aims: The aim of the present work was to study the antimicrobial effect of cell free supernatant (CFS) of probiotics on an Iranian isolate’s biofilm formation. Methods: A l...

Four methods for the assay of human interferon in Vero cells were compared based on the inhibition of viral cytopathic effect (CPE) in tubes, the inhibition of CPE in microplates, the reduction of plaques, and the inhibition of quantitative hemadsorption. For inhibition of CPE, Sindbis virus, vesicular stomatitis virus, poliovirus type 2, and vaccinia virus were used for challenge. In the plaqu...

Monoclonal antibodies were derived against the SA11 simian, NIC bovine, and Wa human rotavirus strains and characterized by enzyme-linked immunosorbent assay, plaque neutralization, and hemagglutination inhibition. Several strain SA11-specific antibodies were found to have neutralizing and hemagglutination-inhibiting capacity.

Present study was designed to compare antioxidant and DNA damage protection of Soxhlet assisted (80% methanol) extract (SEMC) with microwave assisted (80% methanol) extract of Michelia champaca Linn. (MEMC). The in vitro antioxidant activity of SEMC and MEMC were tested for DPPH, hydroxyl radical (OH) by deoxyribose, lipid peroxidation and reducing power capacity. The extracts were also tested ...
