Hybrids of copper cysteamine nanosheets and silver nanocluster ensure superior bactericidal capability via enhanced photodynamic effect.

Over the past decades, bacterial infections resulting from the misuse of antibiotics have garnered significant attention. Among the alternative antibacterial strategies, photodynamic therapy (PDT) has emerged as a promising non-antibiotic approach. However, persistent bacterial biofilms, particularly those composed of gram-negative bacteria with their protective outer membranes, have exhibited remarkable resilience to PDT.

Indocyanine Green Fluorescence Plus Blue Dye for Sentinel Lymph Node Biopsy in Patients Undergoing Neoadjuvant Chemotherapy for Breast Cancer: A Multicenter, Prospective Cohort Study.

Background: Sentinel lymph node biopsy (SLNB) using radioisotope tracer plus blue dye is the gold standard after neoadjuvant chemotherapy (NAC) in initially cN1 breast cancer patients, but clinical use still has limitations. This study aims to examine diagnostic performance of dual indocyanine green (ICG) and methylene blue tracing for SLNB in patients who have completed NAC for breast cancer with initially cN1 disease.

Methods: Adult women (20-80 years of age) scheduled to undergo NAC for biopsy-proven cT0-3N1M0 primary invasive breast cancer were consecutively enrolled in this prospective, multicenter, cohort study.

Mechanisms of He Shi Yu Lin formula in treating premature ovarian insufficiency: insights from network pharmacology and animal experiments.

Objective: He Shi Yu Lin Formula (HSYLF) is a clinically proven prescription for treating premature ovarian insufficiency (POI), and has shown a good curative effect. However, its molecular mechanisms are unclear. This study aimed to investigate the molecular mechanisms of HSYLF and clarify how network pharmacology analysis guides the design of animal experiments, including the selection of effective treatment doses and key targets, to ensure the relevance of the experimental results.

Secondary aluminum dross self-heating enhances hazardous waste vitrification.

This study demonstrates the potential of secondary aluminum dross (SAD) to enhance the vitrifying hazardous waste incineration fly ash (FA) and bottom slag (BS). Based on the CaO-SiO-AlO ternary phase diagram, a liquid phase can be achieved at relatively low temperatures by carefully adjusting the AlO content, particularly when the CaO to SiO ratio is around 0.66.

The causal relationship between gut microbiota and preterm birth: a two-sample Mendelian randomization study.

Background: Preterm birth, a significant global health concern, has been associated with alterations in the gut microbiota. However, the causal nature of this relationship remains uncertain due to the limitations inherent in observational studies.

Purpose: To investigate the potential causal relationship between gut microbiota imbalances and preterm birth.
