Composite barrier membrane for bone regeneration: advancing biomaterial strategies in defect repair.

Bone defects represent a significant challenge in clinical practice, driving the need for innovative solutions that effectively support bone regeneration. Barrier membranes, due to playing a critical role in creating an environment conducive to bone regeneration by preventing the infiltration of non-osteogenic tissues, are widely applied to bone repair. However, inadequate spatial stability and osteogenesis-promoting ability often limit current barrier membranes.

The role of lipid metabolism in cognitive impairment.

Alzheimer's disease (AD), diabetic cognitive impairment (DCI), and vascular dementia (VD) are considered the most common causes of severe cognitive impairment in clinical practice. Numerous factors can influence their progression, and many studies have recently revealed that metabolic disorders play crucial roles in the progression of cognitive impairment. Mounting evidence indicate that the regulation of lipid metabolism is a major factor in maintaining brain homeostasis.

Eighty patients from a single centre were randomly assigned to either the propofol group or the remimazolam group.

Progress in investigating pituitary stalk lesions: A review.

Pituitary stalk lesions are uncommon and are typically identified through pituitary magnetic resonance imaging and screening for causes of diabetes insipidus. Recent literature indicates that pituitary stalk lesions primarily manifest as pituitary stalk interruption syndrome and thickening of the pituitary stalk. The etiology of these lesions is complex and can be divided into major categories: congenital disorders, inflammatory or infectious diseases, and tumors.

Cell-Active, Arginine-Targeting Irreversible Covalent Inhibitors for Non-Kinases and Kinases.

Targeted covalent inhibitors (TCIs) play an essential role in the fields of kinase research and drug discovery. TCI strategies to target more common amino acid side-chains have yet to be demonstrated. Targeting other amino acids would also expand the pharmaceutical industry's toolbox for targeting other tough-to-drug proteins.

Clinical significance of a new early diagnostic model for bladder cancer based on genome-wide microarray profiling of serum exosomal lncRNAs.

Purpose: The aim of our report was to recognize bladder cancer (BC)-specific serum exosome-derived long non-coding RNAs (lncRNAs) profile for early diagnosis of BC.

Methods: Potential BC-specific exosomal lncRNA indicators were discerned by genome-wide microarray profiling analysis of serum exosomes from 10 healthy participants and 10 early stage BC patients (Ta and T1), followed by multi-stage validation through quantitative real-time PCR (qRT-PCR) in BC cells, culture solution as well as 200 serum specimens and 50 tissue specimens from non-muscle-invasive bladder cancer (NMIBC) patients. The diagnostic panel was established using logistic regression and evaluated by receiver-operating characteristic (ROC) curve.

A comparative cohort study of post-COVID-19 conditions based on physical examination records in China.

Background: Coronavirus disease-2019 (COVID-19), caused by SARS-CoV-2 virus infection, is characterized as a multisystem disease, potentially yielding multifaceted consequences on various organs at multiple levels. At the end of 2022, over 90% of the Chinese population was infected by SARS-CoV-2 within 35 days because of adjustments to epidemic prevention and control policies. This short-term change provides an unprecedented opportunity for comparative studies on COVID-19 infection among large populations.

Cold scissors ploughing technique versus electrosurgical excision for hysteroscopic adhesiolysis: a multicenter randomized controlled trial.

Intrauterine adhesions (IUA) may lead to abnormal menstruation, infertility, and pregnancy-related complications. Hysteroscopic separation is the gold standard treatment for IUA and can be performed using a variety of instruments and methods, including cold scissors and electrotomy. However, it is unclear which method is more effective for relieving IUA, restoring uterine anatomy, and improving the pregnancy rate in women of childbearing age.

Status quo and influencing factors of posttraumatic growth of nurses exposed to nurse-to-nurse horizontal violence: a cross-sectional multicenter study.

Background: Post-Traumatic Growth (PTG) relieves physical and psychological stress symptoms in nurses who exposed to nurse-to-nurse horizontal violence (HV), has great intervention potential to reverse the negative effects of HV events. Therefore, in-depth exploration of the overall characteristics of PTG in HV-exposed nurses and its influencing factors are of great practical significance to provide them with precise psychological adaptive interventions.

Objective: This study aims to describe the current state of PTG of HV-exposed nurses and its influencing factors.

A Self-Assembled Nano-Molecular Glue (Nano-mGlu) Enables GSH/HO-Triggered Targeted Protein Degradation in Cancer Therapy.

Molecular glues are promising protein-degrading agents that hold great therapeutic potential but face significant challenges in rational design, effective synthesis, and precise targeting of tumor sites. In this study, we first overcame some of these limitations by introducing a fumarate-based molecular glue handle onto specific ligands of therapeutic kinases (TBK1, FGFR, and Bcr-Abl), resulting in the effective degradation of these important cancer targets. Despite the broad applicability of the strategy, we unexpectedly discovered potent and widespread cytotoxicity across various cell lines, including noncancerous ones, rendering it less effective in cancer therapy.

Efficacy, safety, and biomarker analysis of first-line immune checkpoint inhibitors with chemotherapy versus chemotherapy for advanced gastric cancer: a multicenter, retrospective cohort study.

Background: Recent phase III randomized controlled trials have demonstrated that first-line immune checkpoint inhibitors (ICIs) improve prognosis in advanced HER-2-negative gastric cancer patients with programmed death ligand 1 (PD-L1) combined positive score (CPS) higher than 5. However, these findings are not confirmed in real-world settings, and the benefits in PD-L1 CPS < 5 patients remain controversial.

Methods: In this multicenter, retrospective cohort study, data from across thirteen medical centers were analyzed by inverse probability of treatment weighting for matching, alongside univariate and multivariate COX proportional hazard regression models.

Development and validation of a Prediction Model for Chronic Thromboembolic Pulmonary Disease.

Background: Acute pulmonary embolism (APE) is a critical disease with a high mortality rate, some of the surviving patients may develop chronic thromboembolic pulmonary disease (CTEPD), which affects the patient's prognosis. However, the research on the early diagnosis of CTEPD is limited. This study aimed to establish a prediction model for earlier identification of CTEPD.

KLF14 inhibits tumor progression via FOSL1 in glioma.

Background: Glioma, the most frequent central nervous system malignancy, is often promoted by the overexpression of Fos-like antigen 1 (FOSL1). However, the regulation of FOSL1 remains unexplored. The present study aimed to investigate the regulatory mechanism of FOSL1 to identify potential therapeutic targets for glioblastoma.

Exosomes derived from adipose mesenchymal stem cells promote corneal injury repair and inhibit the formation of scars by anti-apoptosis.

In the corneal wound healing process, epithelial cell re-epithelialization and migration are the critical first steps following an injury. As the disease progresses, orderly regeneration of corneal stromal collagen and mild corneal stromal fibrosis are vital for corneal function reconstruction. Exosomes derived from adipose-derived mesenchymal stem cells (ADSCs-Exos) have emerged as a promising therapy due to their anti-oxidant, anti-apoptosis, and tissue repair properties.
