Discovery of a heparan sulfate binding domain in monkeypox virus H3 as an anti-poxviral drug target combining AI and MD simulations.

Viral adhesion to host cells is a critical step in infection for many viruses, including monkeypox virus (MPXV). In MPXV, the H3 protein mediates viral adhesion through its interaction with heparan sulfate (HS), yet the structural details of this interaction have remained elusive. Using AI-based structural prediction tools and molecular dynamics (MD) simulations, we identified a novel, positively charged α-helical domain in H3 that is essential for HS binding.

Methylcrotonyl-CoA carboxylase 2 supports leucine catabolism to promote mitochondrial biogenesis and alleviate cisplatin-induced acute kidney injury.

Background: Cisplatin is widely used in clinical practice, but its nephrotoxicity severely limits its use. Previous studies have shown that cisplatin-induced acute kidney injury (AKI) is closely related to mitochondrial damage and that alleviating mitochondrial dysfunction can alleviate cisplatin-induced AKI. Methylcrotonyl‑CoA carboxylase 2 (MCCC2) is mainly located in mitochondria, where it catalyzes the catabolism of leucine and maintains mitochondrial function; however, the role of MCCC2 in cisplatin-induced renal injury has not yet been studied.

Boosting Exciton Dissociation and Charge Transfer in Fluorine-Substituted Covalent Organic Frameworks with Biomimetic Electron Pumps for Remarkable Photocatalytic Extraction of Uranium.

Visible-light-driven photocatalytic uranium extraction based covalent organic frameworks (COFs) are green and sustainable, but their performance is severely restricted by a strong exciton effect. Herein, inspired by the physiology of cardiac pacing, a novel fluorine-based COF (PyF-DaS-COF) with a biomimetic electronic pump has been fabricated and used for the photocatalytic extraction of uranium. Both experimental and theoretical calculations confirm that strongly electronegative fluorine plays a crucial role in exciton dissociation and charge transfer.

Exploration of Body Image in Postoperative Patients With Oral Cancer: An Exploratory Sequential Mixed Methods Study.

Background: Postoperative patients with oral cancer are deeply distressed about their body image. However, their true inner feelings and the factors influencing body image remain unclear.

Aims: This study aims to investigate the experience of body image disturbance in patients 3 months after oral cancer surgery and analyze the influencing factors.

Muscle Fiber-Inspired High-Performance Strain Sensors for Motion Recognition and Control.

The rapid development of wearable technology, flexible electronics, and human-machine interaction has brought about revolutionary changes to the fields of motion analysis and physiological monitoring. Sensors for detecting human motion and physiological signals have become a hot topic of current research. Inspired by the muscle fiber structure, this paper proposed a highly stable strain sensor that was composed of stretchable Spandex fibers (SPF), multiwalled carbon nanotubes (MWCNTs), and silicone rubber (Ecoflex).
