The scientific community actively pursuits novel compounds with biological activities. In this context, our study utilized the predicted data mining approach (PDMA), which can efficiently screen out biotransformable precursor candidates to produce new bioactive compounds. The PDMA was applied to tyrosinase (TYR) to form new bioactive hydroxyl compounds from isoxsuprine hydrochloride (isoxsuprine).

Endotracheal tube dislodgement is a common patient safety incident in clinical settings. Current clinical practices, primarily relying on bedside visual inspections and equipment checks, often fail to detect endotracheal tube displacement or dislodgement promptly. This study involved the development of a deep learning, artificial intelligence (AI)-based system for monitoring tube displacement.

Background: Cold as a common environmental stress, causes increased heat production, accelerated metabolism and even affects its production performance. How to improve the adaptability of the animal organism to cold has been an urgent problem. As a key hub of lipid metabolism, the liver can regulate lipid metabolism to maintain energy balance, and O-GlcNAcylation is a kind of important PTMs, which participates in a variety of signaling and mechanism regulation, and at the same time, is very sensitive to changes in stress and nutritional levels, and is the body's "stress receptors" and "nutrient receptors".

Article Synopsis
  • - The study aims to determine how the Stress Hyperglycemia Ratio (SHR) and N-terminal pro-B-type Natriuretic Peptide (NT-proBNP) can predict all-cause mortality in diabetic patients with multivessel coronary artery disease (MVD).
  • - Researchers analyzed data from 1148 diabetic patients, finding that both SHR and NT-proBNP were strong independent predictors of mortality, with the highest risk observed in patients with elevated levels of both markers.
  • - The findings suggest that combining these biomarkers significantly improves the prediction of mortality risk, highlighting their importance in managing diabetic patients with MVD.

Chlorine has been widely used in different advanced oxidation processes (AOPs) for micropollutants removal. In this study, different chlorine-based AOPs, namely medium pressure (MP) UV/chlorine, low pressure (LP) UV/chlorine, and in-situ chlorination, were compared for carbamazepine (CBZ) removal efficiency, energy consumption, and disinfection by-products (DBPs) formation. All three processes could achieve nearly 100% CBZ removal, while the reaction time needed by in-situ chlorination was double the time required by UV/chlorine processes.

Little is known about the association between the free triiodothyronine/free thyroxine (FT3/FT4) ratio and clinical outcomes in euthyroid patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) undergoing percutaneous coronary intervention (PCI). A total of 1448 euthyroid patients with NSTE-ACS who underwent PCI were included in this prospective study. Multivariate Cox regression analysis revealed that there was a significantly increased risk of stroke (hazard ratio [HR] 11.

  • Pyrolysis effectively removes organic contaminants from spent lithium-ion batteries but can create high levels of dissociable fluorine and fluorine-containing wastewater during the process.
  • An in-situ pyrolysis method using Ca(OH)-based materials is proposed to manage fluorine species by adsorbing them and preventing harmful reactions with electrode materials.
  • The optimized experimental conditions successfully reduced the fluorine content in black mass from 3.84 wt% to 2.54 wt%, offering a new approach for controlling fluorine contaminants in the recycling of lithium-ion batteries.

Background And Objective: There are a substantial proportion of elderly patients with ST-segment elevation myocardial infarction (STEMI) miss the optimal time window (12 h from symptom onset) of primary percutaneous coronary intervention (PCI). For these patients, the ideal timing of delayed PCI remains undetermined. Therefore, this study compared the clinical outcomes of early versus late delayed PCI in elderly patients with STEMI.
