Photothermal functionalized antibacterial packaging film with controllable release capability for fruit preservation.

The traditional contact release active packaging film is easily restricted by the strict storage environment and designing a more intelligent release system to achieve lasting food preservation is still a challenge. Herein, a light-responsive thermal-controlled curcumin release packaging film was fabricated by integrating chitosan with Cu-MoO and curcumin (CS/CMC). The addition of filler did not destroy the crystal structure and thermal stability of the chitosan matrix.

Thermal-Driven Curcumin Release Film with Dual-Mode Synergistic Antibacterial Behavior for Efficient Tangerine Preservation.

Antimicrobial packing showed great potential in extending the shelf life of food. However, developing a new biocomposite film with an intelligent and efficient antimicrobial performance is still desirable. Herein, a Fe-MoO encapsulated with curcumin (Cur) filled chitosan-based composite film (CCF films) was prepared by solvent casting method.

Integrated Design of a Dual-Mode Colorimetric Sensor Driven by Enzyme-like Activity Regulation Strategy for Ultratrace and Portable Detection of Hg.

Colorimetric analysis for mercury detection has great application potential in the prevention of health damage caused by mercury in the environment. Sensitivity, selectivity, and portability are core competencies of sensors, and concentrating these properties in a single sensor for efficient mercury detection remains a great challenge. Herein, a hollow structure CuS@CuSe@PVP (CCP) was prepared in which the enzyme-like activities could be activated by Hg due to the antagonism between Hg and Se, inspiring the establishment of a colorimetric method for Hg detection.

Effects of Yangzheng Sanjie Decoction-containing serum mediated by microRNA-7 on cell proliferation and apoptosis in gastric cancer.

Gastric cancer (GC) is one of the most common types of cancer and a leading cause of cancer-associated mortality. MicroRNAs (miRNAs/miRs) are demonstrated to function as oncomiRs or tumor-suppressor-miRs in GC. miR-7 has been identified to be a tumor suppressor of GC by targeting epidermal growth factor receptor (EGFR).
