Comparison of Pediatric and Adult Firearm Deaths to Inform Violence Prevention at Pediatric Trauma Centers.

Introduction: Hospital-based violence intervention programs primarily target adults, raising questions about the effectiveness in preventing pediatric firearm deaths. We hypothesized that pediatric and adult firearm injury deaths are different enough to require unique intervention strategies.

Methods: Retrospective chart review was conducted of medical examiner and trauma center records of firearm-related deaths in the largest metropolitan county in Texas.

Coupling and Energy Transfer between an Exciton in a Semiconductor Quantum Dot and a Surface Plasmon in a Metal Nanoparticle.

The coupling between excitons in semiconductors or molecules and metal nanoparticles has been well-studied, primarily for nanoparticles in their ground electronic state. However, less attention has been given to exciton-nanoparticle interactions when the nanoparticle generates surface plasmons upon incident excitation. In this study, we explore the coupling and energy transfer dynamics between an exciton and the surface plasmon of a metal nanoparticle, forming a "plexciton".

Circumpolar Population Structure, Diversity and Recent Evolutionary History of the Bearded Seal in Relation to Past and Present Icescapes.

The Arctic environment plays a critical role in the global climate system and marine biodiversity. The region's ice-covered expanses provide essential breeding and feeding grounds for a diverse assemblage of marine species, who have adapted to thrive in these harsh conditions and consequently are under threat from global warming. The bearded seal (Erignathus barbatus), including two subspecies (E.

Nerve repair with polylactic acid and inosine treatment enhance regeneration and improve functional recovery after sciatic nerve transection.

Background: Following transection, nerve repair using the polylactic acid (PLA) conduit is an effective option. In addition, inosine treatment has shown potential to promote nerve regeneration. Therefore, this study aimed to investigate the regenerative potential of inosine after nerve transection and polylactic acid conduit repair.

A Long-Term Retrospective Observational Clinical Study Evaluating the Efficacy of Plasma Rich in Growth Factors (PRGF) in the Treatment of Back Pain.

Introduction: Chronic back pain is a long-lasting disorder that is significantly associated with a reduction in the quality of life. Previously, the efficacy of intradiscal and epidural injections of plasma rich in growth factors (PRGF) was demonstrated at 6 months. The objective of this study was to retrospectively examine the medical records of these patients in order to determine whether the observed improvement at the 6-month follow-up was sustained over time.
