Regulation of Oil/Water Separation Using Pyridinium-Based Poly(ionic liquid)s with Prewetted Induced Responsive Transition.

The development of affordable, intelligent dual-separation technology is crucial for the treatment of oil-water mixtures. Pyridinium-based poly(ionic liquid)s (PILs), designed using molecular theory, exhibit unique switching wettability properties, making them ideal for use in both aqueous and oily environments. By prewetting the material's surface with water or oil, the targeted separation of these components becomes feasible.

Role of mutation G255A in modulating pyrethroid sensitivity in insect sodium channels.

A voltage-gated sodium channel (VGSC) plays a crucial role in insect electrical signals, and it is a target for various naturally occurring and synthesized neurotoxins, including pyrethroids and dichlorodiphenyltrichloroethane. The type of agent is typically widely used to prevent and control sanitary and agricultural pests. The perennial use of insecticides has caused mutations in VGSCs that have given rise to resistance in most insects.

Antioxidant taurine inhibits chondrocyte ferroptosis through upregulation of OGT/Gpx4 signaling in osteoarthritis induced by anterior cruciate ligament transection.

Objective: The aim of this study was to investigate the potential molecular mechanisms by which taurine protects against cartilage degeneration.

Methods: The anterior cruciate ligament transection (ACLT) surgery was used to construct an animal model of osteoarthritis (OA). Metabolomics was used to identify characteristic metabolites in osteoarthritic chondrocytes.

Structural analysis of a membrane-associated delta-6 fatty acid desaturase from Prorocentrum micans.

Delta-6 fatty acid desaturases, which play key roles in the biosynthesis of polyunsaturated fatty acids (PUFAs), are membrane-associated enzymes that present significant challenges for isolation and purification, complicating their structural characterization. Here we report the identification and structure-function analysis of a novel Δ6 fatty acid desaturase (PmD6) from the marine alga Prorocentrum micans with substrate preference to α-linolenic acid (18:3n-3). Structural modeling revealed a mushroom-like structure of PmD6 formed by four transmembrane α-helices as a stem and three cytoplasmic domains as a cap.

Functional study of three cases with novel TBX19 variants.

Purpose: Congenital isolated adrenocorticotropic hormone deficiency (CIAD) is an autosomal recessive disorder. This study identifies novel TBX19 variants for CIAD patients, explores its possible effect mechanism at the structural, functional and protein levels, and guides clinicians better understand the condition.

Methods: The clinical characteristics of three CIAD children were summarized.
