The inhibitory effect of Hypericum japonicum on H9N2 avian influenza virus.
Adv Biotechnol (Singap)
November 2024
State Key Laboratory of Biocontrol, School of Life Sciences, Sun Yat-Sen University, Guangzhou, China.
The H9N2 subtype of avian influenza virus (AIV) causes severe immunosuppression and high mortality in view of its frequent co-infection with other pathogens, resulting in significant economic losses in the poultry industry. Current vaccines provide suboptimal immune protection against H9N2 AIV owing to antigenic variations, highlighting the urgent need for safe and effective antiviral drugs for the prevention and treatment of this virus. This study aimed to investigate the inhibitory effects of Hypericum japonicum extract on H9N2 AIV.

Context: This study investigates the reaction mechanism of luteolin with selenium dioxide in ethanol. Through a detailed search for transition states and thermodynamic energy calculations, it was found that the reaction proceeds via two possible pathways, leading to the formation of products P1 and P2, respectively. A common feature of both pathways is that the first elementary step results in the formation of the intermediate INT1.

Department of Chemistry, Faculty of Nano and Bio Science and Technology, Persian Gulf University, Bushehr 75168, Iran.
Molecular dynamics simulations were conducted on mixtures of ionic liquids (ILs) and alcohols, specifically methanol, ethanol, and 1-propanol. Two different ILs, [Mmim][MeSO] and [Bmim][MeSO], were used with varying alcohol mole fractions to investigate the impact of alkyl chain length of cations, alcohol types, and alcohol concentrations on different structural and dynamic properties. Unique characteristics of the ILs were observed due to the varying polarity of solvents and the creation of diverse local environments surrounding the ILs.

CAS Key Laboratory of Mechanical Behavior and Design of Materials, Department of Precision Machinery and Precision Instrumentation, University of Science and Technology of China, Hefei, 230027, P. R. China.
We propose a novel contactless droplet manipulation strategy that combines electrostatic tweezers (ESTs) with lubricated slippery surfaces. Electrostatic induction causes the droplet to experience an electrostatic force, allowing it to move with the horizontal shift of the EST. Because both the EST and the slippery operating platform prepared by a femtosecond laser exhibit a strong binding effect on droplets, the EST droplet manipulation features significant flexibility, high precision, and can work under various operating conditions.

Macrophages play crucial roles in both the innate and adaptive immune systems, contributing to the removal of pathogens and subsequent immune responses. Conversely, aberrant macrophage functions are associated with the onset and progression of various diseases, highlighting macrophages as potential therapeutic targets. Aged garlic extract (AGE) is derived from garlic that has undergone a maturation process of over 10 months in an ethanol solution and contains a variety of bioactive components which are produced in the aging process.
