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...

Endothelial cell-microglia crosstalk mediates heart failure-associated synaptic loss and cognitive impairment in male mice

Cognitive impairment affects 30%–80% of patients with heart failure, yet the mechanisms beyond reduced brain blood flow remain poorly defined. Here we show that circulating factors released during heart failure trigger senescence of brain blood-vessel endothelial cells, which in...

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...

Clinical utility of molecular residual disease detection in early-stage resected EGFR-mutated non-small cell lung cancer

Molecular residual disease (MRD), detected through circulating tumor DNA, has emerged as a promising biomarker for surveillance in patients with early-stage non-small cell lung cancer (NSCLC) following curative-intent resection. Here we report the MRD analysis from the phase 3 EV...

Osimertinib With or Without Chemotherapy in Advanced Non–Small Cell Lung Cancer With EGFR and Concurrent TP53 Mutations

Importance: Combination therapy has emerged as a promising therapeutic approach for patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC). However, its clinical benefit-risk profile remains a focus of ongoing debate. Identifying patients...

Discovery of a peripheral Myh11-expressing nucleus pulposus cell population demontrating therapeutic potential for disc degeneration

Continual turnover of nucleus pulposus (NP) cellularity is critical for maintaining intervertebral disc (IVD) homeostasis; however, the presence and identity of potential progenitor cells within the NP remain unclear. This study identifies NP cells expressing myosin heavy chain 1...

METTL14-dependent N6-methyladenosine modification of FGF16 participates in IGFBP5 deficiency-enhanced angiogenesis.

A-FGF16 axis may offer novel therapeutic strategies for ischemic disease.

METTL14-dependent N6-methyladenosine modification of FGF16 participates in IGFBP5 deficiency-enhanced angiogenesis

Abstract N 6 -methyladenosine (m 6 A) RNA modification plays critical roles in physiological and pathological processes. Our prior study demonstrated that IGFBP5 expression is upregulated in the ischemic limb, whereas endothelial-specific IGFBP5 knockout (Igfbp5 EKO ) protects ag...

Associated Factors and Latent Patterns of Work-Related Musculoskeletal Disorders Among Digestive Endoscopy Nurses: A Multicenter Cross-Sectional Study

Background: Work-related musculoskeletal disorders (WMSDs) have been reported to be very common among hospital workers and particularly nurses. They are assumed or found to be a result of physical workload or poor posture at work and only secondarily a consequence of (general) st...

Gliomas grading prediction using multicenter 3T Magnetic Resonance Spectroscopy

Abstract Background Magnetic Resonance Spectroscopy (MRS) is a non-invasive imaging technique that detects various metabolites in brain tissues, making it essential for the grading of brain gliomas. MRS measures key metabolites such as N-acetyl-aspartate (NAA), choline (Cho), and...
