Two naturally occurring lignanolides, isolated from the tropical climbing shrub Ipomoea cairica, (-)-arctigenin and (-)-trachelogenin, were found to inhibit strongly replication of human immunodeficiency virus type 1 (HIV-1; strain HTLV-III B) in vitro. At a concentration of 0.5 microM, (-)-arctigenin and (-)-trachelogenin inhibited the expression of HIV-1 proteins p17 and p24 by 80-90% and 60-...
We have isolated a substance with anti-retroviral activity from the freshly prepared crude extract of Chelidonium majus L. (greater celandine) by 9-aminoacridine precipitation method and ion exchange chromatography using Dowex-50W/H+ resin followed by the gel filtration on Sephadex-75 column. Elemental and phenol/sulfuric acid method analyses as well as the mass spectrometry of the purified sub...
UNLABELLED The H9N2 influenza viruses that are enzootic in terrestrial poultry in China pose a persistent pandemic threat to humans. To investigate whether the continuous circulation and adaptation of these viruses in terrestrial poultry increased their infectivity to pigs, we conducted a serological survey in pig herds with H9N2 viruses selected from the aquatic avian gene pool (Y439 lineage) ...
We have previously identified two distinct forms of putative viral assembly intermediate complexes, a detergent-resistant complex (DRC) and a detergent-sensitive complex (DSC), in human immunodeficiency virus type 1 (HIV-1)-infected CD4(+) T cells (Y. M. Lee and X. F. Yu, Virology 243:78-93, 1998). In the present study, the intracellular localization of these two viral assembly intermediate com...
Waterfowl are considered to be natural reservoirs of the avian influenza virus (AIV). However, dynamics transmission and evolutionary patterns AIV its subtypes within duck farms in Bangladesh remain poorly documented. Hence, a cross-sectional study was conducted nine districts between 2019 2021, determine prevalence H5 H9, as well identify risk factors phylodynamics H5N1 clades circulating dome...
. The reactive epitope of heat shock protein 60 (HSP60) of Helicobacter pylori to its monoclonal antibody (H9) was determined, and its synthesized peptide designated pH9 was used for ELISA. The patients with H. pylori infection had significantly lower titers of pH9 antibody than did uninfected patients. In C57BL/6 mice immunized intraperitoneally with the pH9 peptide with Freund's complete adju...
