Hydrogel-based nonwoven with persistent porosity for whole-stage hypertonic wound healing by regulating of water vaporization enthalpy.

Moisture induced by wound exudate is crucial throughout the wound repair process. The dressing directly affects the absorption, permeation, and evaporation of the wound exudate. However, most dressings in clinical often result in excessive dryness or moisture of wound due to their monotonous structure and function, leading to ineffective thermodynamic control of evaporation enthalpy.

TMSB4Y restrains sphingomyelin synthesis via de novo purine synthesis to exert a tumor suppressor function in male esophageal squamous cell carcinoma.

Y chromosome genes play a vital role in sex difference of cancer. The dysregulation and functional implications of Y chromosome genes in esophageal squamous cell carcinoma (ESCC) remains elusive. Here, we analyze the Y chromosome gene signature and identify TMSB4Y as an emerging prognostic predictor in male ESCC.

Antioxidant packaging films based upon starch-montmorillonite with forsythia flower extract: characterization and application.

Plastic pollution is one of the most acute environmental problems in the world, so active packaging materials made from biodegradable natural polymers have received widespread attention in recent years.

Synthesis of 2-imidazoles copper-catalyzed homo/cross-coupling of oxime acetates.

A facile and practical protocol to construct 2-imidazoles by applying an oxime acetate block as the sole component oxidative homo/cross-coupling catalyzed by Cu(I) was developed. This strategy provides a straightforward method to produce a series of substituted 2-imidazoles in moderate to excellent yields. The transformation process is straightforward to operate and is considered as a readily available catalytic system exhibiting good substrate compatibility, eliminating the necessity for pre-functionalization of azides or the use of additives.

A protein O-GlcNAc glycosyltransferase regulates the antioxidative response in Yersinia pestis.

Post-translational addition of O-linked N-acetylglucosamine (O-GlcNAc) to proteins is commonly associated with a variety of stress responses and cellular processes in eukaryotes, but its potential roles in bacteria are unclear. Here, we show that protein HmwC acts as an O-GlcNAc transferase (OGT) responsible for O-GlcNAcylation of multiple proteins in Yersinia pestis, a flea-borne pathogen responsible for plague. We identify 64 O-GlcNAcylated proteins (comprising 65 sites) with differential abundance under conditions mimicking the mammalian host (Mh) and flea vector (Fv) environments.

Insect ribosome-rescuer Pelo-Hbs1 complex on sperm surface mediates paternal arbovirus transmission.

Arboviruses can be paternally transmitted by male insects to offspring for long-term persistence, but the mechanism remains largely unknown. Here, we use a model system of a destructive rice reovirus and its leafhopper vector to find that insect ribosome-rescuer Pelo-Hbs1 complex expressed on the sperm surface mediates paternal arbovirus transmission. This occurs through targeting virus-containing tubules constituted by viral nonstructural protein Pns11 to sperm surface via Pns11-Pelo interaction.
