Targeting the Thy-1 mechanotransduction regulator rescues regenerative wound healing and induces hair follicle neogenesis under high tension

Abstract Mechanical tension is a critical driver of hypertrophic scar (HS) formation, primarily by inducing the differentiation of fibroblasts into pathological myofibroblasts. However, the upstream mechanotransduction regulators that initiate this fibrotic cell fate switch remai...

Comparison of transumbilical single-port and conventional multi-port laparoscopic hepatectomy for benign liver lesions

Transumbilical single-port laparoscopic hepatectomy represents a further refinement of minimally invasive liver surgery, but its safety and perioperative value remain insufficiently defined. This study aimed to compare transumbilical single-port laparoscopic hepatectomy with conv...

Study on the pathogenic mechanisms and clinical treatment of advanced glycation end products (AGEs) in diabetic complications

The accumulation of Advanced Glycation End Products (AGEs), resulting from the Maillard Reaction formed via exogenous intake from food and a hyperglycemic internal environment in the body, can cause or exacerbate various complications of Diabetes Mellitus. This article discusses...

Acridine-Based[68Ga]Ga- and [18F]AlF-Labeled PSMA RadiotracersEnabling High-Contrast PET Imagingwith Minimized Undesired Retention

Abstract Prostate-specific membrane antigen (PSMA)-targeted radioligands have achieved clinical success in prostate cancer imaging, yet nonspecific uptake in normal tissues remains a challenge. Here, we developed a series of acridine-based PSMA ligands and systematically investig...

Mefatinib versus gefitinib as a first-line treatment for EGFR-mutated non-small cell lung cancer: a randomized, double-blind, multicenter phase III study

Mefatinib, a novel second-generation epidermal growth factor (EGFR) tyrosine kinase inhibitor that has shown promising antitumor activity in targeting non-small cell lung cancer (NSCLC) with common and uncommon EGFR- activating mutations. In this phase III, randomized, double-bli...

Microfluidic engineering of CeO2/Peptide nanosheet-integrated bioactive hydrogel microspheres for multi-enzymatic biomimetic catalytic therapy of osteoarthritis

Osteoarthritis (OA) is a degenerative joint disease characterized by chronic inflammation and oxidative stress-induced cartilage degeneration, yet effective disease-modifying therapies remain limited. Herein, we report a CeO 2 /peptide nanosheet (CeP)-integrated hydrogel microsph...

Estimating individualized gonadotropin starting doses in women with PCOS: a target-driven machine learning model for GnRH-antagonist stimulation

Abstract Background Women with polycystic ovary syndrome (PCOS) are prone to excessive ovarian response and ovarian hyperstimulation syndrome (OHSS) during controlled ovarian stimulation, whereas overly conservative gonadotropin (Gn) dosing reduces oocyte yield and efficiency. Th...

Neural regulation in lung cancer: from mechanisms to new therapeutic perspectives

Lung cancer remains a leading cause of cancer-related deaths worldwide. Despite advances in targeted therapy and immunotherapy, treatment outcomes are often constrained by tumor heterogeneity and the complex tumor microenvironment. Recent studies highlight the critical role of th...

Comprehensive genomic characterization of extraintestinal pathogenic Escherichia coli isolated from neonates: multiple center insights into virulence, resistance, and transmission dynamics

Neonatal extraintestinal pathogenic Escherichia coli (ExPEC), which can cause severe long-term sequelae by systemic infections, is gradually becoming the primary pathogen threatening neonatal health. The lack of large-scale genomic epidemiological investigation hinders further un...

Risk factors for incident chronic kidney disease following unilateral nephrectomy: a systematic review and meta-analysis

Nephrectomy is standard for kidney tumors and living kidney donation, but postoperative chronic kidney disease (CKD) is a critical determinant of long-term outcomes. Risk factors for incident CKD after unilateral nephrectomy remain incompletely synthesized. PubMed, Embase, Web of...

A mitochondria-related 9-gene induced sputum signature for severe asthma: an integrative transcriptomic analysis with external validation

OBJECTIVE: Severe asthma is biologically heterogeneous, and airway-derived biomarkers for disease stratification remain limited. We aimed to identify a mitochondria-related induced sputum transcriptomic signature associated with severe asthma. METHODS: Two public induced sputum m...

Post-injury high-sensitivity C-reactive protein to lymphocyte ratio and nonunion risk in adult extremity fractures: evidence from a multicenter retrospective cohort

Early immuno-inflammatory response serves a critical role in the process of fracture healing, and both excessive and insufficient activation after injury may predict adverse outcomes. This study aimed to investigate the association between post-injury high-sensitivity C-reactive...
