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.

Person-Centered Social Determinants and Neighborhood-Level Deprivation Associated With Disability in Hispanic People With Multiple Sclerosis.

Background And Objectives: Multiple sclerosis (MS)-related disability in Hispanic people with MS is associated with inequities in social determinants of health (SDOH) as measured by composite indices of areal-level census data. Studies of individual-level measures of SDOH are lacking. This study examined the separate and joint effects of person-centered SDOH indicators and an area-level composite on MS disability measures.

Spatial and Temporal Analysis, and Machine Learning-Based Prediction of PCB Water Concentrations in U.S. Natural Water Systems.

Data on dissolved phase water concentrations of polychlorinated biphenyls (PCBs) from 32 locations across the U.S. were compiled from reports, Web sites, and peer-reviewed papers, spanning 1979-2020, resulting in 5132 individual samples.
