Assessing Health Disparities in Digital Services and Technologies During and After the COVID-19 Pandemic: A Pooled Cross-Sectional Analysis Using HINTS Data.

Introduction: Digital health techniques were adopted faster during COVID-19, but the gap remains. This study analyzes how the digital gap affected pandemic patient portal uptake during and after. Patient portals improve physician connections and patient health information access, increasing health outcomes.

β-receptor blocker enhances anti-tumor immunity via inhibiting lactate-induced norepinephrine metabolism of macrophages during malignant pleural effusion.

Introduction: Malignant pleural effusion (MPE) is associated with poor quality of life and mortality in patients with tumors. In clinical practice, we observed that patients with malignant pleural effusion (MPE) and concurrent heart disease exhibited a decrease in MPE volumes following treatment with β-receptor blockers for heart disease. Immunosuppressive tumor microenvironment was found to play a substantial role in the progression of MPE, and mainly attributed to tumor-associated macrophages (TAMs).

Foliar application of 24-epibrassinolide enhances leaf nicotine content under low temperature conditions during the mature stage of flue-cured tobacco by regulating cold stress tolerance.

Background: Low temperatures disrupt nitrogen metabolism in tobacco, resulting in lower nicotine content in the leaves. 24-epibrassinolide (EBR) is a widely used plant growth regulator known for its roles in enhancing cold tolerance and nitrogen metabolism. Nevertheless, it remains unclear whether EBR enhances leaf nicotine content under low temperature conditions during the mature stage of flue-cured tobacco.

Superconjugated Anthraquinone Carbonyl-Based Covalent Organic Framework as Anode Material for High-Performance Aqueous Ammonium-Ion Batteries.

Covalent organic frameworks (COFs) have recently been emerged as promising anode candidates for aqueous ammonium ion batteries (AAIBs), but suitable COFs need to be developed and the energy storage mechanisms need to be further investigated. Here we report an anthraquinone carbonyl-containing COF as anode for AAIBs, which exhibits a high specific capacity of 141 mAh g-1 at 0.1 A g-1 and good cycling stability with 90% retention after 8000 cycles at 6 A g-1.

MnSOD non-acetylation mimic knock-in mice exhibit dilated cardiomyopathy.

Manganese superoxide dismutase (MnSOD/SOD2) is an essential mitochondrial enzyme that detoxifies superoxide radicals generated during oxidative respiration. MnSOD/SOD2 lysine 68 acetylation (K68-Ac) is an important post-translational modification (PTM) that regulates enzymatic activity, responding to nutrient status or oxidative stress, and elevated levels have been associated with human illness. To determine the in vivo role of MnSOD-K68 in the heart, we used a whole-body non-acetylation mimic mutant (MnSOD) knock-in mouse.
