ABSTRACT Background Excessive lipogenesis of the skin triggers some dermatological concerns, such as enlarged pores, acne, and blackheads. Although topical drug treatments can offer temporary relief, their prolonged usage may lead to side effects dryness, irritation, or allergic reactions. Consequently, development safer efficacious ingredients in cosmetics for managing sebum overproduction represents a significant yet challenging endeavor. Aim Saponins were extracted from tea ( Camellia sinensis ) seed meal purified by macroporous resin order investigate impact saponins (TSS) on lipid production human immortalized sebaceous cells. Moreover, we attempted reveal underlying mechanism TSS sebosuppression effect SZ95 sebocytes stimulated linoleic acid (LA). Methods The compositions chemical structures determined using UV–vis absorption spectrum, Fourier transform‐infrared (FTIR) ultra‐high‐performance liquid chromatography‐mass spectrometry analysis. An vitro model cellular accumulation induced LA was established. Total synthesis intracellular assessed through Nile Red staining, while triglyceride, cholesterol, fatty acids quantified commercially assay kits. Western blot quantitative real‐time polymerase chain reaction employed analyze protein expression levels involved AMP‐activated kinase (AMPK)/mammalian target rapamycin (mTOR) pathway well downstream mRNA expressions sterol regulatory element‐binding protein‐1 (SREBP‐1), peroxisome proliferator‐activated receptor γ (PPARγ), synthase (FAS). localizations SREBP‐1 within cytoplasm nucleus characterized immunofluorescence staining. Results Five identified TSS, all which oleanic acid‐type pentacyclic triterpenes. treatment significantly alleviated LA‐induced sebocytes. In addition, activated AMPK/mTOR downregulated transcription factors enzymes, including SREBP‐1, PPARγ, FAS. blocked nuclear transfer nucleus. Conclusion sebocytes, exhibited sebosuppressive revealed inhibited total lipids acids. anti‐lipogenesis activation enzymes Additionally, translocation. These results justify potent new candidate modulating

Activated carbon from Camellia oleifera shells for adsorption of Y(iii): experimental and DFT studies

RSC Advances, Год журнала: 2024, Номер 14(6), С. 4252 - 4263

Yttrium is an important rare earth element and widely used in fields such as special glass preparation, metallurgy, materials science. However, it difficult to recover yttrium ion waste from dilute solutions with traditional processes, resulting a significant of resources. The simple, effective, easy-to-operate adsorption method the most promising for recovering yttrium, which great significance sustainable development industry. In this study, activated carbon was prepared Camellia oleifera fruit shells (COS) using phosphoric acid activation, efficient recovery Y(iii) shell studied. Adsorption equilibrium data showed that had capacity 35.41 mg g-1, indicating potential ions. by COS consistent Langmuir model, were pseudo second-order kinetic process primarily chemical adsorption. After adsorption, surface contained large amounts N, O, Y, stably adsorbed. mechanisms on three types studied through DFT calculations. results interacted atoms surfaces form new bonds. capacities different carbons decreased order C I > II C.
