Secondary metabolites are important bioactive compounds for diet and medicine. This study optimizes the extraction of hydroethanolic herbal extracts using an EDGE (Energized Dispersive Guided Extraction) system, evaluates their antioxidant capacity, and analyzes correlations among antioxidant activity, total phenolic content, and individual compounds. A Doehlert matrix design was used to optimize extraction, having temperature and time as independent variables, and total phenolic content (mg GAE/g) as the response, quantified via the Folin-Ciocalteu method.

Extreme event attribution assesses how climate change affected climate extremes, but typically focuses on single events. Furthermore, these attributions rarely quantify the extent to which anthropogenic actors have contributed to these events. Here we show that climate change made 213 historical heatwaves reported over 2000-2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.

Therapeutic drug monitoring (TDM) is vital for effective optimization of pharmacological treatments. In this study, we engineered a chromatography column that is sensitive to temperature fluctuations, thereby enabling safe and straightforward TDM without relying on organic solvents. Silica beads were modified by applying poly(N-isopropylacrylamide) (PNIPAAm) hydrogels, using a condensation reaction to modify the initiator, followed by radical polymerization to integrate the PNIPAAm hydrogel.

Temperature-sensitive Transient Receptor Potential (TRP) channels contribute to modulating skin vascular tone. Their role in Raynaud's Phenomenon (RP) remains unknown. We aimed to investigate TRPs expression in the skin, along with microvascular reactivity to cooling in patients with primary and secondary RP, compared with healthy subjects.

Background: Phrenic nerve injury during mediastinal tumor resection can lead to significant postoperative diaphragmatic dysfunction. Current intraoperative protection techniques are imprecise and lack real-time feedback. We aimed to develop and validate a quantifiable, multimodal neuroprotective strategy.
