Mechanical stretch-induced IGF2 overexpression in epidermal keratinocytes promotes hypertrophic scar formation through the IGF1R/p-c-Jun axis.

Insulin-like growth factor 2 (IGF2) is a mitogenic peptide hormone expressed by various tissues. Although it is three times more abundant in serum than IGF1, its physiological and pathological roles are yet to be fully understood. Previous transcriptome sequencing studies have shown that IGF2 expression is increased in hypertrophic scar (HS); however, its role in HS formation and the underlying mechanism remains elusive.

Construction and immunological evaluation of recombinant adenovirus vaccines of new novel NADC34-PRRSV strains in pigs.

Introduction: Porcine reproductive and respiratory syndrome virus (PRRSV) causes reproductive and respiratory diseases in sow herds and piglets. The emergence of ORF5 RFLP 1-7-4-like (NADC34-like) PRRSV strain in China has brought a new round of challenges to PRRSV prevention.

Methods: In addition, recombinant adenovirus vaccine candidates against the newly emerged NADC34-like strain were constructed in the study; the immunogenicity of the vaccine was investigated in piglets.

Kappa opioid receptor internalisation-induced p38 nuclear translocation suppresses glioma progression.

Background: Recent studies have implicated a role for perioperative medications in determining patient outcomes after surgery for malignant tumours, including relapse and metastasis.

Methods: A combined approach spanned molecular, cellular, and organismal levels, including bioinformatics, immunohistochemical staining of clinical and animal samples, RNA sequencing of glioblastoma multiforme (GBM) cells with Ingenuity Pathway Analysis, lentiviral-mediated gene expression modulation, in vitro cell experiments, and in vivo orthotopic tumour transplantation.

Results: We observed a significant correlation between increased kappa opioid receptor (KOP receptor) expression and better prognosis in patients with glioma.

Cross sectional associations of physical activity and sleep with mental health among Chinese university students.

Objective: This study aimed to examine the levels of physical activity (PA), sleep, and mental health (MH), specifically depression, anxiety, and stress, among Chinese university students. It also aimed to analyze the influencing factors of MH, providing a theoretical foundation for developing intervention programs to improve college students' mental health.

Methods: A stratified, clustered, and phased sampling method was employed.

Tailoring Acid-Salt Hybrid Electrolyte Structure for Stable Proton Storage at Ultralow Temperature.

The critical challenges in developing ultralow-temperature proton-based energy storage systems are enhancing the diffusion kinetics of charge carriers and inhibiting water-triggered interfacial side reactions between electrolytes and electrodes. Here an acid-salt hybrid electrolyte with a stable anion-cation-HO solvation structure that realizes unconventional proton transport at ultralow temperature is shown, which is crucial for electrodes and devices to achieve high rate-capacity and stable interface compatibility with electrodes. Through multiscale simulations and experimental investigations in the electrolyte employing ZnCl introduced into 0.
