Segetalin B promotes bone formation in ovariectomized mice by activating PLD1/SIRT1 signaling to inhibit γ-secretase-mediated Notch1 overactivation.

Segetalin B (SB) has shown promise in mitigating osteoporosis in ovariectomized (OVX) mice, though its underlying mechanisms remain unclear. This study investigates how SB promotes bone formation through Phospholipase D1 (PLD1) activation in OVX models. In vitro, bone marrow-derived mesenchymal stem cells (BMSCs) from OVX mice were cultured for osteogenic differentiation.

Enhancing CO photoreduction to CO with 100 % selectivity by constructing heterojunctions and regulating open metal sites in Au/FeO/MIL-101(Fe) catalysts.

The widespread utilization of fossil fuels has resulted in a significant increase in CO emissions, leading to a variety of environmental issues. The photocatalytic conversion of CO into fuel presents an effective solution to both the energy crisis and environmental warming. Therefore, the selection of a suitable catalyst is paramount.

A review of copper-based Fenton reactions for the removal of organic pollutants from wastewater over the last decade: different reaction systems.

In recent years, as global industrialization has intensified, environmental pollution has become an increasingly serious problem. Improving water quality and achieving wastewater purification remain top priorities for environmental health initiatives. The Fenton process is favored by researchers due to its high efficiency and ease of operation.

The catalytic oxidation performance of toluene over the Ce-Mn-O catalysts: Effect of synthetic routes.

Ce-Mn-O catalysts were synthesized by impregnation (CM-IM), co-precipitation (CM-CP), citrate sol-gel (CM-SG) and hydrothermal (CM-HT) methods. The synthesis methods exhibited a great impact on the physicochemical properties of catalysts, resulting in different catalytic activity. The catalytic oxidation activity of toluene followed the sequence: CM-HT (T: 234 °C; T: 246 °C) > CM-SG (T: 242 °C; T: 249 °C) > CM-CP (T: 243 °C; T: 259 °C) > CM-IM (T: 251 °C; T: 261 °C), which was consistent with the sequence of surface relative percentage of C, Ce, Mn, O and r values.
