Oral Lactoferrin-Responsive Formulation Anchoring around Inflammatory Bowel Region for IBD Therapy.

Oral formulation is the ideal treatment method for inflammatory bowel disease (IBD) therapy, but the mucosal damage and diarrhea symptoms impede the drug retention around the inflammatory region, severely limiting IBD therapeutic efficacy. To address this, an oral astaxanthin (Ast) precise delivery formulation is developed with the selective Ast anchoring around the inflammatory region by the novel lactoferrin (LF)-responsive flocculation. This formulation also heightens the apparent solubility of Ast with the minimized edible safety risks for the edible raw materials.

Orchestrated desaturation reprogramming from stearoyl-CoA desaturase to fatty acid desaturase 2 in cancer epithelial-mesenchymal transition and metastasis.

Background: Adaptative desaturation in fatty acid (FA) is an emerging hallmark of cancer metabolic plasticity. Desaturases such as stearoyl-CoA desaturase (SCD) and fatty acid desaturase 2 (FADS2) have been implicated in multiple cancers, and their dominant and compensatory effects have recently been highlighted. However, how tumors initiate and sustain their self-sufficient FA desaturation to maintain phenotypic transition remains elusive.

Ex Situ pH-Induced Reversible Wettability Switching for an Environmentally Robust and High-Efficiency Stain-Proof Coating.

Novel Nanoliposomes Synergistically Modulated by Sitogluside and Dioscin: Stability, Bioavailability, and Capacity To Alleviate Hyperuricaemia.

Cholesterol (Cho) is commonly used to stabilize nanoliposomes; however, there is controversy on the relationship between Cho and health. In this study, we developed a novel multifunctional nanoliposome utilizing structurally similar sitogluside (SG) and dioscin (Dio) instead of Cho to anchor the phospholipid bilayer and synergistically modulate the membrane properties of the nanoliposome (DPPC or DOPC). The storage and gastrointestinal tract stability experiment demonstrated that the changes of physical and chemical properties, including the significantly reduced size and Dio retention rate of nanoliposomes synergistically modulated by SG and Dio compared to those of SG alone, regulated nanoliposomes.

Regulating Carbon Vacancies and Undercoordinated Mo Sites in MoC Catalysts Toward Photo-Thermal Catalytic Conversion of Biomass Into H Fuel.

The conversion of biomass into chemical fuels is exciting but quite challenging in the development of an effective conversion strategy to generate easily-separated products without energy consumption. Herein, a lignocellulosic biomass-to-H conversion system via photo-thermal catalysis over MoC hierarchical nanotube catalysts in an acidic solution, in which the lignocellulose is hydrolyzed to small organic molecules (such as glucose, etc) by dilute HSO, and then the resulting glucose is oxidized by MoC catalyst to generate H are reported. During the photo-thermal catalytic processes, the carbon vacancy in MoC catalysts results in the generation of undercoordinated Mo sites, which act as active sites for both biomass oxidation and H generation reactions.
