Abstract This study investigates the antiviral efficacy of chitosan‐stabilized silver nanoparticles (AgNPs) against Foot‐and‐Mouth Disease virus (FMDV), a highly contagious pathogen affecting cloven‐hoofed animals. In vitro experiments demonstrated that AgNPs effectively inhibited FMDV replication in dose‐dependent manner. At concentration 1.56 μg/ml, exhibited no cytotoxicity to baby hamster kidney 21 (BHK21) cells while achieving complete deactivation at titer 10 3 TCID 50 and inhibiting...
A large-scale cross-sectional seroprevalence study of dengue (DEN) and Japanese encephalitis (JE) was conducted in Khammouane province, Lao PDR, as part the initial baseline health impact assessment Nam Theun 2 hydroelectric dam construction project. Health surveys were performed between May 2007 February 2008 with serum samples collected from healthy individuals involved resettlement program 16 villages (total surveyed population 4,369). Hemagglutination inhibition assay using flavivirus...
Rural farming communities in northern Vietnam do not routinely practice vaccination for influenza A viruses (IAV) either humans or poultry, which enables us to study transmission intensity via seroepidemiology. Using samples from a longitudinal cohort of households, we determined the number symptomatic and asymptomatic human infections seasonal IAV avian A/H9 over 2 years. As expected, detected virologically confirmed acute cases humans, as well large numbers subclinical seroconversions...
Background and purpose Ischemic stroke (IS) is classified into clinical subtypes likely influenced by various lipid components. Nevertheless, the roles of apolipoprotein A-I (apoA-I), B (apoB), apoB/apoA-I ratio in different IS remain underexplored. This study aimed to investigate differential distribution plasma apoA-I apoB levels among evaluate predictive value assessing disease severity. Methods In this study, 406 patients were categorized three IS-subtypes based on manifestations imaging...
