Contact Cooling-Induced ELOVL4 Enhances Skin Wound Healing by Promoting the Inflammation-to-Proliferation Phase Transition.

Empirical evidence indicates that the rate of wound healing varies through different seasons, where it is higher in spring and fall but lower in summer and winter, suggesting adequate temperatures may promote wound healing via an unknown mechanism. Here we show that adequate temperature facilitates wound healing by inducing the expression of Elongation of Very Long Chain Fatty Acid Elongase 4 (ELOVL4) that curtails the inflammation phase. Using skin injury and skin organoids models, bulk- and single-cell RNA-sequencing and spatial transcriptomics analysis, and functional perturbations, we first demonstrate that adjusting skin surface temperature to 20°C by contact cooling markedly increases the rate of wound healing via upregulating ELOVL4 in the injured epidermis.

Dynamics of Globular Proteins when Interacting with Zwitterionic Silica Nanoparticles by Nuclear Magnetic Resonance Spin Relaxation.

The many emerging applications of nanoparticles in diverse fields in chemistry and biology require the characterization of interactions between nanoparticles and surrounding biomolecules such as proteins. Nuclear magnetic resonance spin relaxation of proteins, which is highly sensitive to interactions with nanoparticles, contains rich information about protein mobility and binding kinetics. The interactions of globular proteins with silica nanoparticles differ markedly from those with liposome nanoparticles, although both are driven by electrostatic forces.

The global, regional, and national patterns of change in the burden of chronic kidney disease from 1990 to 2021.

Background: Chronic kidney disease (CKD) is a major global public health problem with increasing prevalence and a huge health and economic burden. Diabetes mellitus and hypertension are major risk factors for CKD, and CKD is associated with cardiovascular disease and end-stage renal disease. Understanding the prevalence and burden of CKD is essential for the development of prevention and control strategies.

MBD2 promotes epithelial-to-mesenchymal transition (EMT) and ARDS-related pulmonary fibrosis by modulating FZD2.

Objective: To investigate the role and underlying mechanism of Methyl-CpG binding domain protein 2 (MBD2) in the pathogenesis of acute respiratory distress syndrome (ARDS)-related pulmonary fibrosis.

Methods: Murine models for ARDS-related pulmonary fibrosis were established in wildtype or MBD2 knockout mice, expressions of MBD2 were determined with immunohistochemistry (IHC), immunofluorescence, and western blot. Epithelial-to-mesenchymal transition (EMT) was detected with determined with decreased expression of E-cadherin and increased expressions of N-cadherin, Vimentin, and α-smooth muscle actin (α-SMA).

Trimethylamine-N-oxide enhances drought tolerance in Eucalyptus by increasing photosynthesis.

Drought stress significantly reduces agricultural productivity, threatening global food security and timber production. Although trimethylamine-N-oxide (TMAO) has been shown to enhance drought tolerance in plants such as Arabidopsis thaliana and tomato, the physiological and molecular mechanisms by which it regulates drought tolerance in plants remain unclear. In this study, we investigated the physiological and transcriptomic changes in Eucalyptus under drought stress following exogenous TMAO treatment.
