Surface double defects-dominated TiO with high liquid phase stability for smart SERS sensing of dye additives in foods.

Surface defect engineering is an effective strategy to regulate the physical and chemical properties of semiconductors for a wide range of applications. Herein, a surface-highly-reduced anatase TiO (R-TiO) with double defects (surface oxygen vacancy defect and Ti energy level defect) was developed as a plasmon-free surface-enhanced Raman scattering (SERS) substrate for ultrasensitive detection of food additives. Abundant surface oxygen vacancies enable R-TiO to exist stably in liquid phase, which realizes a smart SERS detection for dye target molecules due to evading fluorescent interference from analytes, while SERS enhancement of analytes cannot be observed on the solid phase substrate at all.

However, important RNA regulators in kidney cancer still need further exploration. In this study, we collected regulators representing different types of RNA modification and identified the prognosis-related RNA regulators in kidney cancer patients.

Catheter ablation for atrial tachycardia in pediatric patients: a single-center experience.

Purpose: Atrial tachycardia is an uncommon supraventricular tachycardia in children. It is often drug-resistant and likely to occur concomitantly with tachycardia-induced cardiomyopathy, making radiofrequency catheter ablation the preferred treatment. The aim of this study was to assess the feasibility, safety, and effectiveness of radiofrequency catheter ablation for the treatment of different types of atrial tachycardia in children, particularly in those with drug-resistant and tachycardia-induced cardiomyopathy.

Temperature cycling between 4 °C and 37 °C could reduce Salmonella viability in low-moisture foods.

Low-moisture foods (LMFs) have been linked to Salmonella transmission due to the remarkable resilience of Salmonella against desiccation, allowing its survival for extended periods. Being metabolically inactive, Salmonella in LMFs exhibit extraordinary resistance to inactivation treatments. This study proposes a novel strategy for mitigating Salmonella in LMF products through a temperature cycling (TC) approach.

Synergy Effects of HPV E6-E7 Encoding mRNA and Nucleic Acid Immunostimulators Improve Therapeutic Potential in TC-1 Graft Tumor.

Cervical cancer is the second most common cancer among women globally and the most prevalent cancer in developing countries, which was caused by human papillomavirus (HPV) infection. Messenger RNA (mRNA) vaccines have opened up new avenues for vaccine development and pandemic preparedness with potent scalability, which may possess the potential antitumor effects of an mRNA-HPV therapeutic vaccine containing nononcogenic E6 and E7 proteins. Here, we reported a lipid nanoparticle (LNP) plus nucleic acid immunostimulators (CPG 1018 and Poly I:C) mRNA vaccine platform.

Quasi-One-Dimensional Fibrous Phosphorus: An Air-Stable Low-Symmetry Semiconductor with High Anisotropy.

Due to their novel optical and optoelectronic properties, 2D materials have received increasing interest for optoelectronics applications. However, when the width of the channel layer decreases to the nanoscale, the properties of 2D materials can be seriously influenced due to the boundary defects and the approximation of physical dimensions and mean free path of the electron. That brings many challenges to developing novel electronics.

Brain-to-heart cholinergic synapse-calcium signaling mediates ischemic stroke-induced atrial fibrillation.

Stroke-related cardiovascular diseases have attracted considerable attention, with atrial fibrillation (AF) being among the most frequent complications. Despite increasing clinical evidence, experimental models of stroke-induced AF are still lacking, hindering mechanistic discoveries and the development of adequate therapeutics targeting this stroke-heart syndrome (SHS). This study aims to create a rat model of ischemic stroke-induced AF (ISIAF) and to explore the efficacy and mechanism of Wenxin Keli (WK), an antiarrhythmic Chinese medicine.

Comprehensive Analysis of Genes Across the Genome Uncovers Potential Functions in Sexual Reproduction and Abiotic Stress Tolerance.

The Domain of Unknown Function 506 () belongs to the PD-(D/E) XK nuclease superfamily and has been reported to play critical roles in growth and development as well as responses to abiotic stresses.

A Randomized Controlled Trial of Adding Deep Parasternal Intercostal Plane Block to Interpectoral-Pectoserratus Plane Block in Breast Cancer Surgery.

Background: The interpectoral-pectoserratus plane block is expected to anesthetize the lateral breast, but it is unclear whether the deep parasternal intercostal plane block may enhance recovery by providing analgesia to the medial breast.

Methods: Patients undergoing breast cancer surgery were randomly assigned to receive either the interpectoral-pectoserratus block (single block) or interpectoral-pectoserratus combined with deep parasternal intercostal block (combined block). The primary outcome was the quality of recovery-15 questionnaire score assessed at 24 hours postoperatively.

She-Chuang-Si-Wu-Tang Alleviates Inflammation and Itching Symptoms in a Psoriasis Mouse Model by Regulating the Th17/IL-17 Axis via the STAT3/MAPK Pathways.
