Molecular dynamics work on thermal conductivity of SiGe nanotubes.

Context: SiGe nanotubes (SiGeNTs) hold significant promise for applications in nanosolar cells, optoelectronic systems, and interconnects, where thermal conductivity is critical to performance. This study investigates the effects of length, diameter, temperature, and axial strain on the thermal conductivity of armchair and zigzag SiGeNTs through molecular dynamics simulations. Results indicate that thermal conductivity increases with sample length due to ballistic heat transport and decreases with temperature as phonon scattering intensifies.

Puerarin Promotes the Migration and Differentiation of Myoblasts by Activating the FAK and PI3K/AKT Signaling Pathways.

Puerarin, a flavonoid compound present in the roots of radix , contributes to the development of tissues such as bone and nerve, but its role in skeletal muscle regeneration remains unclear. In this study, we employed C2C12 myoblasts and barium chloride (BaCl)-based muscle injury models to investigate the effects of puerarin on myogenesis. Our study showed that puerarin stimulated the migration and differentiation of myoblasts in vitro.

Diagnostic value of interferon-γ release assay in patients with COPD complicated with pulmonary tuberculosis.

Background: The common diagnostic methods for tuberculosis have been showing reduced sensitivity among chronic obstructive pulmonary disease patients. This study was conducted to evaluate and analyse the diagnostic value of an interferon-γ release assay in COPD patients complicated with pulmonary tuberculosis.

Methods: A nested case-control study was conducted on 123 COPD patients hospitalized at the Fifth Hospital of Shijiazhuang, Hebei Province, from January 2019 to June 2021.

Embracing the Future of Clinical Trials in Radiotherapy: An NRG Oncology CIRO Technology Retreat Whitepaper on Pioneering Technologies and AI-Driven Solutions.

This white paper examines the potential of pioneering technologies and artificial intelligence (AI)-driven solutions in advancing clinical trials involving radiotherapy. As the field of radiotherapy evolves, the integration of cutting-edge approaches such as radiopharmaceutical dosimetry, FLASH radiotherapy, image-guided radiation therapy (IGRT), and AI promises to improve treatment planning, patient care, and outcomes. Additionally, recent advancements in quantum science, linear energy transfer/relative biological effect (LET/RBE), and the combination of radiotherapy and immunotherapy create new avenues for innovation in clinical trials.

Photodynamic therapy with a novel photosensitizer inhibits DSS-induced ulcerative colitis in rats via the NF-κB signaling pathway.

Introduction: Ulcerative colitis (UC) is an inflammatory bowel disease characterized by inflammation and ulceration of the digestive tract.

Methods: Photodynamic therapy (PDT) with a novel photosensitizer LD was used to treat UC rat models to explore the therapeutic effect and mechanism of LD-PDT on UC. 16S ribosomal RNA was used to detect the composition of Gut microbiota.
