In Vivo tissue healing mechanism at the intestinal anastomosis site following high-frequency electric welding.

To investigate the effect of High-Frequency Electric Welding (HFEW) on intestinal tissue healing, we performed end-to-end anastomosis experiments in New Zealand rabbits. Within one week post-surgery, animals exhibited normal vital signs, replaced necrotic tissue with healthy collagen, and showed improved tissue strength while inflammation decreased. By day 60, tissue pathology and function fully recovered, resembling normal tissue.

Metabolic Alterations of Short-Chain Organic Acids in the Elderly Link Antibiotic Exposure with the Risk for Depression.

Background: Our previous study showed that antibiotic exposure was linked to depressive symptomatology in community-dwelling older adults in China. Our current study aims to explore the underlying mechanisms by assessing the intermediated effects of circulating short-chain organic acids (SCOAs) on this association.

Methods: Depressive symptoms were screened by the 30-item Geriatric Depression Scale (GDS-30).

Quality of life and subjective well-being comparison between traumatic, nontraumatic chronic spinal cord injury, and healthy individuals in China.

Background: Differentiating between traumatic and non-traumatic spinal cord injuries (NT-SCI) is critical, as these classifications may significantly impact patients' health outcomes and overall well-being, potentially resulting in differences in treatment protocols and therapeutic efficacy.

Objective: This study aims to compare the quality of life (QoL) and satisfaction with life (SWL) among individuals with traumatic spinal cord injuries (T-SCI), NT-SCI, and the healthy population in China.

Method: A quantitative, cross-sectional survey was conducted between July and December 2020 in the Rehabilitation and Physiotherapy Department of Tongji Hospital, Hubei University of Science and Technology.

Performance Enhancement by Integrating the Ionic Thermoelectric Generator with a Photovoltaic Cell.

The global solar market is booming with a rapid growth in installed integrated devices, while photovoltaic (PV) systems are suffering from waste heat, which causes the decline of the photovoltaic conversion efficiency (PCE). This study presents the seamless integration of the ionic thermoelectric generator (iTEG) layer with traditional PV modules, facilitating the exploitation of waste heat and augmenting the overall power output. Experimental results validate the effectiveness of the iTEG, demonstrating substantial power generation and a consistent energy output.

Noble-Metal-Free Cocatalysts Reinforcing Hole Consumption for Photocatalytic Hydrogen Evolution with Ultrahigh Apparent Quantum Efficiency.

Achieving efficient and sustainable hydrogen production through photocatalysis is highly promising yet remains a significant challenge, especially when replacing costly noble metals with more abundant alternatives. Conversion efficiency with noble-metal-free alternatives is frequently limited by high charge recombination rates, mainly due to the sluggish transfer and inefficient consumption of photo-generated holes. To address these challenges, a rational design of noble-metal-free cocatalysts as oxidative sites is reported to facilitate hole consumption, leading to markedly increased H yield rates without relying on expensive noble metals.
