We used a series of modified/substituted GGH analogues to investigate the kinetics of Cu(II) binding to ACTUN peptides. Rules for rate modulation by 1 and 2 sphere interactions were established, providing crucial insight into elucidation of the reaction mechanism and its contribution to biological copper transport.

Background: Active vitamin D metabolites, including 25-hydroxyvitamin D (25D) and 1,25-dihydroxyvitamin D (1,25D), have potent immunomodulatory effects that attenuate acute kidney injury (AKI) in animal models.
Methods: We conducted a phase 2, randomized, double-blind, multiple-dose, 3-arm clinical trial comparing oral calcifediol (25D), calcitriol (1,25D), and placebo among 150 critically ill adult patients at high-risk of moderate-to-severe AKI. The primary endpoint was a hierarchical composite of death, kidney replacement therapy (KRT), and kidney injury (baseline-adjusted mean change in serum creatinine), each assessed within 7 days following enrollment using a rank-based procedure.

Background: Experience with icodextrin use in children on long-term peritoneal dialysis is limited. We describe international icodextrin prescription practices and their impact on clinical outcomes: ultrafiltration, blood pressure control, residual kidney function (RKF), technique and patient survival.
Methods: We included patients under 21 years enrolled in the International Pediatric Peritoneal Dialysis Network (IPPN) between 2007 and 2024, on automated PD with a daytime dwell.

Many soft, tough materials have emerged in recent years, paving the way for advances in wearable electronics, soft robotics, and flexible displays. However, understanding the interfacial fracture behavior of these materials remains a significant challenge, owing to the difficulty of quantifying the respective contributions from viscoelasticity and damage to energy dissipation ahead of cracks. This work aims to address this challenge by labeling a series of polymer networks with fluorogenic mechanophores, subjecting them to T-peel tests at various rates and temperatures, and quantifying their force-induced damage using a confocal microscope.

Increased adiposity and chronic psychosocial stress (CPS) are plausible modifiable contributors of the recent increase in early-onset colorectal cancer (EOCRC). We conducted an 8-week randomized controlled pilot trial evaluating the feasibility and acceptability of time restricted eating (TRE) (daily ad libitum eating between 12-8pm) and Mindfulness ("Mindfulness for Beginners" course from the Calm app) among young adults. Participants were randomized to the following groups: TRE ( = 10); Mindfulness ( = 11); TRE & Mindfulness ( = 11); or Control ( = 11).

Minoritized racial, ethnic, sexual, and gender communities and populations face profound health disparities and their engagement in research remains low. In a randomized controlled trial, our community-based participatory research partnership tested the efficacy of ChiCAS, an HIV prevention intervention designed to increase pre-exposure prophylaxis use among Spanish-speaking transgender Latinas. Of 161 eligible Spanish-speaking transgender Latinas screened, we enrolled 144, achieving an 89% participation rate, and retained 94% at 6-month follow-up.
