Synthesis, Preclinical Evaluation, and First-in-Human Assessment of ICG-PSMA-D5: A PSMA-Targeted Probe for Fluorescence-Guided Surgery of Prostate Cancer.

Precise surgical resection of prostate cancer (PCa) is a significant clinical challenge due to the impact of positive surgical margins on postoperative outcomes. Fluorescence-guided surgery (FGS) enables real-time tumor visualization using fluorescent probes. In this study, we synthesized and evaluated an indocyanine green (ICG)-based PSMA-targeted near-infrared probe, , for intraoperative imaging of PCa lesions.

Activation of locus coeruleus noradrenergic neurons rapidly drives homeostatic sleep pressure.

Homeostatic sleep regulation is essential for optimizing the amount and timing of sleep for its revitalizing function, but the mechanism underlying sleep homeostasis remains poorly understood. Here, we show that optogenetic activation of locus coeruleus (LC) noradrenergic neurons immediately increased sleep propensity following a transient wakefulness, contrasting with many other arousal-promoting neurons whose activation induces sustained wakefulness. Fiber photometry showed that repeated optogenetic or sensory stimulation caused a rapid reduction of calcium activity in LC neurons and steep declines in noradrenaline/norepinephrine (NE) release in both the LC and medial prefrontal cortex (mPFC).

Risk Factors for Symptoms in Patients With Heterotopic Gastric Mucosa in the Upper Esophagus.

This study is aimed at comparing the clinical characteristics and histological types of symptomatic and asymptomatic patients with heterotopic gastric mucosa in the upper esophagus (HGMUE) and exploring the factors influencing the occurrence and severity of laryngopharyngeal reflux (LPR) symptoms in these patients. HGMUE is a potential cause of LPR symptoms. This retrospective analysis evaluated 70 patients with HGMUE using a detailed questionnaire.

Glycoprotein 350-targeted chimeric antigen receptor T-cell therapy for nonneoplastic chronic active Epstein-Barr virus infection: a case report.

Background: Chronic active Epstein-Barr virus (CAEBV) infection is a rare disease in which the Epstein-Barr virus (EBV) persists and replicates, causing chronic symptoms and fatal complications. The treatment of CAEBV is still evolving. Our case report showed a new therapy for CAEBV.

L-Carnitine Improves Muscle Nutrient Metabolism and Intestinal Health in High-Fat-Fed Carp ().

L-Carnitine is widely recognized for its involvement in lipid metabolism, but its effects on muscle quality and gut health in carp have not been well studied. The research aimed to investigate how L-carnitine influences muscle quality and intestinal health in high-fat-fed carp. The study was separated into four groups that received either the standard diet, a high-fat diet (HFD), or a HFD supplemented with 500 mg/kg L-carnitine (LLC), or a HFD supplemented with 1000 mg/kg L-carnitine (HLC) for 56 days.
