Chronic wounds, due to their high prevalence, are a serious global health concern. Effective therapeutic strategies can significantly accelerate healing, thereby reducing the risk of complications and alleviating the economic burden on healthcare systems. Although numerous experimental studies have investigated wound healing, most rely on qualitative observations or quantitative direct measurements.

Stable-isotope resolved metabolomics (SIRM) is a powerful approach for characterizing metabolic states in cells and organisms. By incorporating isotopes, such as C, into substrates, researchers can trace reaction rates across specific metabolic pathways. Integrating metabolomics data with gene expression profiles further enriches the analysis, as we demonstrated in our prior study on glioblastoma metabolic symbiosis.

Descending necrotizing mediastinitis (DNM) is a rare and potentially life-threatening condition characterized by the rapid spread of infection within the mediastinum. This severe form of mediastinitis poses a significant challenge to clinicians due to its aggressive nature and potential for rapid deterioration. In this case report, we present a challenging case of descending necrotizing mediastinitis in a 39-year-old patient with persistent pyrexia and an extended hospital stay in the intensive care unit (ICU), cardiothoracic unit (CTU), and surgical intensive care unit (SICU).

One of still outstanding issues in protein folding is to be able to directly observe structural changes occurring along the folding pathway. Herein, we report on changes of the viscoelastic properties for a single protein molecule measured along its mechanically-induced unfolding and refolding trajectories. We use a model system, the I27 poly-protein, and investigate its conformational changes force-clamp AFM (FC-AFM) spectroscopy.
View Article and Find Full Text PDFAortic regurgitation is the third most common valve lesion with increasing prevalence secondary to an ageing population. Transthoracic echocardiography plays a vital role in the identification and assessment of aortic regurgitation and proves essential in monitoring severity and determining the timing of intervention. Building on the foundations of previous British Society of Echocardiography (BSE) recommendations, this BSE guideline presents an update on how to approach an echocardiographic assessment of aortic regurgitation.
