Study on the catalytic mechanism and water resistance of Cu-Mn-Sn catalyst for CO elimination.

CO in coal mine underground spaces can easily cause casualties among miners. The humidity in coal mines is relatively high, and traditional Cu-Mn catalysts are prone to deactivation. Compared to traditional Cu-Mn catalysts, doping with Sn enhances the activity and water resistance of Cu-Mn catalysts.

Triglyceride-glucose index and triglyceride-glucose-body mass index as prognostic factors for early stage breast cancer patients receiving neoadjuvant chemotherapy.

Background: Insulin resistance (IR) is closely associated with the risk of breast cancer. The triglyceride-glucose (TyG) index and the triglyceride-glucose-body mass index (TyG-BMI) are considered surrogate indicators of IR; however, their prognostic value in breast cancer patients has not been discussed. The purpose of this study is not only to explore whether the TyG index and the TyG-BMI can predict the chemotherapy response and long-term prognosis of breast cancer patients receiving neoadjuvant chemotherapy (NACT) but also to investigate the possible mediating mechanism and to analyze the relationship between TyG-related enzyme expression and drug resistance and prognosis.

Urea Complexation for Docosahexaenoic Acid Enrichment from Crypthecodinium cohnii Oil: Using Water as the Urea Solvent.

Based on the observation that urea, water, and ethyl esters (EE) can form gypsum-like mixtures, this study explored the feasibility of employing water as a solvent for urea in the urea complexation method to enrich n-3 polyunsaturated fatty acids with docosahexaenoic acid (DHA)-containing ethyl esters (DHA- EE) from Crypthecodinium cohnii as the material. Under the conditions of a urea/DHA-EE ratio of 3, a water/DHA-EE ratio of 0.75, a mixing temperature of 65℃, and a cooling temperature of 20℃, a concentrate containing over 90% DHA was achieved.

Metabolic profiles and potential antioxidant mechanisms of hawk tea.

Hawk tea has received increasing attention for its unique flavor and potential health benefits, with antioxidant function being one of its significant bioactivities. However, the metabolic profiles, potential antioxidant components, and action mechanisms of different types of hawk tea are still unclear. In this study, the chemical components of five hawk teas were determined using untargeted metabolomics.

Carbon quantum dots amplify beneficial effects of EGCG against neural injuries by NLRP3 inflammasome after intracerebral hemorrhage.

Neuroinflammation plays an indispensable role in neural damages after ICH, responsible for the induced high mortality and poor prognosis. NLRP3 inflammasome, which is known mediated by ROS, has been widely documented to aggravate brain injuries. Therefore, suppressing neural injuries by ROS/NLRP3 pathway may be beneficial in treating ICH.
