Following literature screening and data extraction, the bias risk assessment tool in the Cochrane reviewer handbook 5.

Effect of polyethoxylated flavonoids (PMFs)-loaded citral and chitosan composite coatings on citrus preservation: From the perspective of fruit resistance.

Previous studies have shown that polymethoxylated flavonoids-loaded citral emulsion (PCT) can inhibit the growth and reproduction of Penicillium in citrus; however, PCT is difficult to apply to fruit preservation due to its high fluidity and volatility. Therefore, in this study, we combined PCT with chitosan (CS) to investigate the effect of a composite coating on citrus preservation. The results showed that compared to the control group, the CS-PCT group could effectively reduce the decay rate and maintain moisture availability, color difference, and hardness.

Citrus Carotenoid Extracts Promote ROS Accumulation and Induce Oxidative Stress to Exert Anti-Proliferative and Pro-Apoptotic Effects in MDA-MB-231 Cells.

Citrus fruits are economically significant crops worldwide, as they contain various bioactive compounds that possess health-promoting properties. Carotenoids, as the most important component in citrus, exhibit notable pharmacological activities, such as antioxidation and anticancer, which make carotenoids valuable in the prevention and treatment of breast cancer. In this study, after treatment with carotenoid extracts from XiYou (XY) and ZaoHongQiCheng (ZH), we evaluated the cytotoxicity, apoptosis, antioxidant system, and oxidative stress induced by ROS overproduction and MMP damage in MDA-MB-231 cells.

Ultrathin 2D Pd/Cu Single-Atom MOF Nanozyme to Synergistically Overcome Chemoresistance for Multienzyme Catalytic Cancer Therapy.

Single-atom nanozymes (SAzymes) have obtained increasing interest to mimic natural enzymes for efficient cancer therapy, while challenged by chemoresistance from cellular redox homeostasis and the interface of reductive species in tumor microenvironment (TME). Herein, a dual single-atomic ultrathin 2D metal organic framework (MOF) nanosheet of multienzyme (Pd/Cu SAzyme@Dzy) is prepared to synergistically overcome chemoresistance for multienzyme enhanced cancer catalytic therapy. The Pd SAzyme exhibits peroxidase (POD)-like catalytic activity for overcoming chemoresistance via disturbing cellular redox balance.

Oxygen Bridge Formed by Doping Nonmetal Atoms into Cationic Vacancies To Enhance the Photoelectrochemical Oxygen Evolution Reaction.

To enhance photoelectrochemical (PEC) water splitting for renewable energy conversion, the conventional strategy is doping nonmetals into anionic vacancies. Compared to anionic vacancies, cationic vacancies are theoretically more effective and reliable for anchoring nonmetals owing to their larger radii and unique advantages. The current research mainly focuses on anionic vacancies, while there are few studies on cationic vacancies due to high formation energy and challenging characterizations by convenient techniques.

Dual Active Centers Linked by a Reversible Electron Station as a Multifunctional Nanozyme to Induce Synergetically Enhanced Cascade Catalysis for Tumor-Specific Therapy.

Nanozymes have shown great promise in reactive oxygen species (ROS)-mediated tumor therapy with mitigated side effects but are normally limited by the complex tumor microenvironment (TME). Herein, to overcome the adverse effects of TME, such as tumor hypoxia and high endogenous glutathione (GSH), an aptamer-functionalized Pd@MoO nano-hydrangea (A-Pd@MoO NH) is constructed for high-efficiency cancer therapy. Utilizing the irregular shape characteristics of nano Pd, the A-Pd@MoO NH nanozyme simultaneously exposes catalase-like Pd(111) and oxidase-like Pd(100) surface facets as dual active centers.

Water-resistant organic-inorganic hybrid perovskite quantum dots activated by the electron-deficient d-orbital of platinum atoms for nitrogen fixation.

Due to their special physicochemical properties, organic-inorganic hybrid perovskite quantum dots (OIP QDs) are ideal and potential catalysts for the nitrogen reduction reaction (NRR). However, the OIP QD-based NRR is limited by poor water resistance, competitive suppression by the hydrogen evolution reaction, and inefficient active sites on the catalyst surfaces. Herein, to ensure an efficient NRR in aqueous solution, a water-resistant polycarbonate-part-encapsulated heterojunction of Zn,Pt co-doped PbO-MAPbBr (Pt/Zn/PbO/PC-Zn/MAPbBr) is prepared through one-step electrospray-based microdroplet synthesis.
