A 9 + 1 multi-agent collaborative teaching model for clinical reasoning: integrating large language models into medical education

Clinical reasoning—the cognitive and metacognitive processes through which clinicians collect and interpret patient information, generate and test diagnostic hypotheses, and make clinical decisions—is a core competency in medical education. Since 1956, clinical educators have inn...

Temporal dynamics of PrEP adherence, self-efficacy, and risk perception among men who have sex with men in western China: a cross-lagged panel network analysis

<title>Abstract</title> Background Pre-exposure prophylaxis (PrEP) effectively reduces HIV infection risk among men who have sex with men (MSM), but its benefit depends on adherence. The longitudinal item-level relationships among PrEP adherence, self-efficacy, and risk perceptio...

Selective Intrinsically Photosensitive Retinal Ganglion Cells Ablation Regulates Myopia Development Through the Choroid/MAPK Pathway

Purpose This study investigates the role of selective ablation of intrinsically photosensitive retinal ganglion cells (ipRGCs) in regulating axial length (AL) and scleral remodeling during myopia progression.Methods Three-week-old pigmented guinea pigs were randomly assigned to f...

Fuzuloparib in combination with apatinib versus fuzuloparib alone for recurrent ovarian cancer: a randomized, open-label, phase 2 trial

A randomized, open-label, phase 2 trial assessed fuzuloparib (a PARP inhibitor) plus apatinib (a vascular endothelial growth factor receptor [VEGFR] inhibitor) versus fuzuloparib alone in patients with recurrent ovarian cancer (ROC). Patients with ROC who had failed ≥ 2 lines of...

Levistilide A promotes ferroptosis through the RNF40-HSP90α axis and inhibit colorectal cancer lung metastasis

Abstract The molecular mechanisms underlying lung metastasis of colorectal cancer (CRC) remain largely elusive, and effective therapeutic agents are still lacking. In this study, we identify levistilide A (LeA) as a potential anti-metastatic agent against CRC lung metastasis. We...

TREM2 regulates continual efferocytosis of apoptotic neurons by monocyte-derived macrophages via AKT-PFKFB2-mediated glycolytic reprogramming after acute ischemic stroke

Efficient clearance of apoptotic neurons is crucial for mitigating secondary injury after acute ischemic stroke (AIS). Although monocyte-derived macrophages (MDMs) rapidly infiltrate the ischemic brain and upregulate triggering receptor expressed on myeloid cells 2 (TREM2) expres...

MRI-based radiomic models of subchondral bone for predicting the occurrence of knee osteoarthritis

To extract the MRI-based radiomic features of subchondral bone, and establish multi-regional radiomic models and delta-radiomic models for predicting the 2-year risk of knee osteoarthritis (KOA). The data used in this study were obtained from the osteoarthritis initiative (OAI)....

BifunctionalIonophores for Cuproptosis Activation:Dual Targeting of Copper and Fe–S Protein Homeostasis

Abstract Cellular resilience to therapy often arises from adaptive mechanisms that safeguard iron–sulfur (Fe–S) proteins. Here, we present a rational strategy to overcome such resilience by integrating two synergistic vulnerabilities, copper toxicity and Fe–S cluster homeostasis,...

Sirtuin 4 knockout exacerbates cardiac injury in septic cardiomyopathy via activating the MAPK-JNK pathway

Septic cardiomyopathy (SCM) significantly contributes to mortality among septic patients, and its mechanism is closely related to abnormal inflammatory responses. Previous studies revealed the essential role of the Sirtuin4 gene in cardiomyocyte and myocardial function; however,...

Targeting a CDH1–TK1–dependent DNA Synthesis Pathway Overcomes Chemoresistance in Acute Myeloid Leukemia

ABSTRACT Relapsed and refractory acute myeloid leukemia (AML) remains difficult to treat, in part because leukemic cells adapt to nucleoside analogue‐induced replication stress. Here, we identify thymidine kinase 1 (TK1) as a functional contributor to chemotherapy resistance in A...

Synchronous ReactiveOxygen Species Scavenging andImmunomodulation for Autoimmune Uveitis Therapy by a MannosylatedBiomimetic Nanocloak

Abstract Autoimmune uveitis is a recurrent, vision-threatening inflammatory disease that demands precise and ongoing treatment. However, current therapies have limitations in ocular targeting, in controlling reactive oxygen species (ROS), and in regulating key inflammatory pathwa...

Pregnancy loss and prevalent cardiometabolic multimorbidity: a two-stage individual participant data analysis of CHARLS, ELSA, and HRS

Cardiovascular disease remains the leading cause of death worldwide, and cardiometabolic multimorbidity (CMM) is associated with substantially higher mortality and reduced life expectancy. Pregnancy loss is common and has been linked to later cardiovascular risk, but multinationa...

Integrative analysis of network pharmacology and machine learning suggests potential anti-colorectal cancer mechanisms of Taohong-Siwu decoction

Colorectal cancer (CRC) remains one of the most prevalent malignancies worldwide, characterized by high morbidity and poor prognosis. Although traditional Chinese herbal formulas have shown promising therapeutic potential, their multi-target mechanisms in CRC are still poorly und...
