Engineering a biomimetic multiphasic suture anchor system for enhanced rotator cuff enthesis regeneration

Abstract Conventional suture anchor methods in rotator cuff repair often fail to replicate the native tendon-to-bone interface, leading to re-tears due to stress concentrations and poor biological integration at anchor sites. To address these challenges, we engineered a biomimeti...

Climate adaptation as evolvability

Abstract Standard approaches to climate adaptation, commonly understood as the protection of infrastructure, social systems, and ecosystems from adverse climate impacts, are too closely tied to the biological concept of adaptation and the ecological notion of stability . Instead,...

Eco-evolutionary feedback reshapes competitive dynamics in an orchard fly system

The feedback between competition and evolution is central to hypotheses about the origin and maintenance of species diversity. Yet, whether competition-induced evolution is sufficiently rapid, consistent, and strong to maintain diversity on ecological timescales remains unresolve...

Neurological Pupil Index and Outcome After Cardiac Arrest in Children: Single-Center, Retrospective Cohort, 2018–2023

OBJECTIVES: To determine the association between abnormal pupillary reactivity using automated infrared pupillometry and unfavorable outcome after pediatric cardiac arrest (CA). DESIGN: Single-center, retrospective, cohort study, 2018-2023. SETTING: Large tertiary PICU in the Uni...

Nuclear activities and interactome of the NS5 protein of tick-borne encephalitis virus

Orthoflaviviruses are RNA viruses responsible for significant diseases in humans, domesticated animals, and wildlife. Their NS5 protein is central in viral replication, functioning both as an RNA-dependent RNA polymerase and a methyltransferase, while also modulating cellular pro...

SNAP Benefit Cycles and Antiretroviral Therapy Adherence Among Adults With HIV

This cohort study examines the association between timing of receipt of Supplemental Nutrition Assistance Program (SNAP) benefits and adherence to oral antiretroviral therapy among SNAP recipients with HIV.

A systematic review of environmental factors in AI-based fall risk prediction models for community-dwelling older adults

Falls commonly occur in home environments, where conditions can increase fall risk. Identification and mitigation of environmental hazards are critical components of fall prevention. However, artificial intelligence (AI)-based fall prediction models have largely focused on indivi...
