Optically tunable catalytic cancer therapy using enzyme-like chiral plasmonic nanoparticles.

Cascade enzymatic reactions in living organisms are fundamental reaction mechanisms in coordinating various complex biochemical processes such as metabolism, signal transduction, and gene regulation. Many studies have attempted to mimic cascade reactions using nanoparticles with enzyme-like activity; however, precisely tuning each reaction within complex networks to enhance the catalytic activity remains challenging. Here, we present enzyme-like chiral plasmonic nanoparticles for optically tunable catalytic cancer therapy.

Aspartate aminotransferase-to-platelet ratio index as a novel predictor of early mortality in heat stroke patients: a multi-centre retrospective study.

Background: The aspartate aminotransferase-to-platelet ratio index (APRI) is an effective non-invasive marker for chronic liver dysfunction. Given that heat stroke patients often suffer from poor prognosis due to multi-organ involvement, with liver injury and coagulation dysfunction being of particular concern, this study aims to investigate whether APRI can comprehensively reflect liver injury and coagulation dysfunction in heat stroke patients and explore its relationship with 28-day mortality.

Methods: This retrospective study analysed electronic medical records from patients treated at 57 grade A tertiary hospitals in China from May 2005 to May 2024.

Short communication: Evaluating laying curve models and estimating genetic parameters for egg production traits in chickens.

The Qingyuan partridge chicken, a highly valued indigenous breed in China, requires optimised egg production traits to maximise economic returns. This study analysed weekly egg production data from 6 776 Qingyuan partridge chickens to compare the Grossman and Wood models in fitting individual egg-laying curves and identify the most robust model for estimating egg production persistency. Genetic parameters were estimated for three key traits: age at first egg (AFE), cumulative egg number up to 28 weeks (EN), and persistency derived from the Wood model, alongside weekly egg numbers using a random regression model.

Disparities in Antidiabetic Medication Discontinuation Between Non-Hispanic White and Black Beneficiaries in Medicare Across Diabetes Belt and Surrounding Area.

Objective: To assess racial and geographic disparities in antidiabetic medication discontinuation among Medicare beneficiaries with type 2 diabetes (T2D) in or around Diabetes Belt (DB) areas, with a specific focus on differences between non-Hispanic (NH) white and NH Black individuals.

Study Design: A retrospective cohort analysis was conducted on Medicare beneficiaries who initiated metformin and used antidiabetic medications during 2011-2015, including metformin, sulfonylureas, insulin, DPP-4 inhibitors, GLP-1 receptor agonists, SGLT2 inhibitors, and thiazolidinediones. Medication discontinuation was defined as a gap of 90 days or more without any antidiabetic medications.

Inhibiting EZH2 complements steroid effects in Duchenne muscular dystrophy.

Duchenne muscular dystrophy (DMD) is a devastating X-linked disorder caused by dystrophin gene mutations. Despite recent advances in understanding the disease etiology and applying emerging treatment methodologies, glucocorticoid derivatives remain the only general therapeutic option that can slow disease development. However, the precise molecular mechanism of glucocorticoid action remains unclear, and there is still need for additional remedies to complement the treatment.
