Feline Kobuvirus in Domestic Cats in Northern Vietnam: Molecular Insights Reveal Adaptive Evolution in VP1 Protein

Feline kobuvirus (FKoV) has been linked to diarrheal disease in cats and has recently emerged in several Asian countries. This study aimed to investigate the epidemiological and genetic characterization of FKoV in domestic cats in northern Vietnam from 2022 to 2025. In total, 244...

Influenza Vaccine Effectiveness Against Pneumonia and COPD Exacerbations Among Patients with Chronic Obstructive Pulmonary Disease in Thailand: A National Test-Negative Design Study, 2013–2024

ABSTRACT Background/Objectives Influenza infection is a major trigger of pneumonia and acute exacerbations among patients with chronic obstructive pulmonary disease (COPD). However, national laboratory-confirmed evidence on influenza vaccine effectiveness (VE) in this high-risk p...

Understanding brand loyalty formation through emotional engagement: evidence from social media marketing in Thailand

Purpose This study examines how emotional engagement, customisation, entertainment, interaction, trendiness and electronic word-of-mouth (eWOM) combine to shape brand loyalty among Thai luxury-brand consumers exposed to high-intensity social-commerce environments. The study is fr...

Human scFv inhibiting broad coronavirus replication: a pandemic preparedness candidate

The ongoing emergence of zoonotic coronaviruses (CoVs) and the rapid evolution of viral variants underscore the need for broadly active antiviral agents. The relatively conserved S2 subunit of the coronavirus spike protein is an attractive target for developing pan-coronavirus th...

Mechanical-press torrefaction of Napier grass for bio-coke production: effects of temperature and pressure on densification, fuel properties, and CO2 gasification behavior

This study investigated a mechanical-press torrefaction-assisted carbonization route for producing Napier grass-derived bio-coke. Napier grass was first torrefied under mechanical pressure at 280–340 °C and 20–70 MPa, followed by carbonization at 1000 °C. The effects of torrefact...

Altered ScalingDynamics in Liquid Crystal DropletCoalescence: The Role of Surfactants and Marangoni Stresses

Abstract In the clean-interface limit, the early-stage coalescence of liquid droplets typically follows the standard neck-growth scaling r∝(γR/ρ)1/4t1/2 where inertia dominates. When a surfactant is present, the dynamics can depart substantially from the baseline due to additiona...

Prevalence and Determinants of Sexually Transmitted Infections Among Thai Men Who Have Sex with Men Enrolled in National Pre-Exposure Prophylaxis Program: A Real-World Cross-sectional Study

Background: Sexually transmitted infections (STIs) remain a major public health concern among men who have sex with men (MSM). This study estimated STI prevalence and associated factors among MSM enrolled in Thailand’s national pre-exposure prophylaxis (PrEP) registry under the U...

Starter Unit Promiscuity of Dictyostelid Type III Polyketide Synthases Generates Diverse Acylphloroglucinols with Antimicrobial Activity

Abstract Cavenderia subdiscoidea and Cavenderia ungulata are dictyostelid social amoebae found in northern Thailand. Genomic analysis identified two type III polyketide synthase genes, designated cspks and cupks. Heterologous expression of both genes in Aspergillus oryzae NSAR1 y...

Advanced functional biochar-based hybrid nanocomposites for electrochemical sensing platforms in environmental monitoring

Biochar (BC), a stable, carbon-rich material produced by heating biomass, is increasingly used in electrochemical sensing, particularly in hybrid nanocomposite forms, because hybridization can improve electrical conductivity, catalytic activity, surface area, and interfacial char...

Differential Response of Three Legume Crops to Integrated Nutrient Management: Synergistic Effects of Reduced Nitrogen and Bradyrhizobium-Based Biofertilizer

This study investigates the impact of selected soil parameters and integrated fertilizer formulations on the productivity of three legume crops—mung bean, soybean, and cowpea—in order to identify the optimal strategies to maximize yields through reduced nitrogen and bio-augmentat...

Corn Stover-DerivedLewis Acid Carbon Catalyst forEfficient Hantzsch Synthesis of 1,4-Dihydropyridines

Abstract The development of sustainable heterogeneous catalysts from renewable biomass is an important strategy for advancing green organic synthesis. In this work, a series of Lewis acid carbon catalysts were prepared from corn stover via AlCl3-assisted activation and thermal ca...

Dietary Application of Synergistically Degraded Low-Molecular-Weight Chitosan to Promote Health and Antioxidant Responses in Pacific White Shrimp (Litopenaeus vannamei)

This study evaluated the potential of synergistically degraded low-molecular-weight chitosan (LMW-CS) as a functional feed additive to promote growth, antioxidant capacity, innate immunity, and disease resistance in Pacific white shrimp (Litopenaeus vannamei). High-molecular-weig...

Evaluation of recombinant TgGRA14 as a diagnostic antigen for detection of Toxoplasma gondii antibodies in cattle

Toxoplasma gondii ( T. gondii ) a widespread zoonotic parasite infecting various host species. Since cattle serve as major intermediate hosts for T. gondii , giving a significant public health concern, developing effective diagnostic tools is essential. This study evaluated the s...
