Niacin promotes motor function recovery after spinal cord injury via Hcar2‐dependent microglia immunometabolic regulation

open access: yesClinical and Translational Medicine, Volume 16, Issue 5, May 2026.
• The activation of the microglial Hcar2 receptor by niacin initiates intracellular signalling that induces metabolic reprogramming. • This metabolic shift is characterized by increased oxidative phosphorylation. Consequently, microglia polarize from a proinflammatory state toward an anti‐inflammatory, reparative phenotype.

Statistical Discrimination of Urinary Steroid Biomarkers in the Athlete Biological Passport: A Novel Approach to an Abnormal Steroid Profile Score (ASPS)

open access: yesDrug Testing and Analysis, Volume 18, Issue 5, Page 608-618, May 2026.
The study developed a single Abnormal Steroid Profile Score (ASPS) to improve interpretation of the Athlete Biological Passport steroid module. Using Bayesian modelling and logistic regression, biomarker patterns from laboratory and doping control data successfully discriminated between doped and clean individuals, with improved classification ...

Catchment Influences on Carbon Stable Isotope Variation in Trout; Might It Be Methane?

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Trout stable carbon isotope values vary significantly and appear to relate to catchment characteristics. Low carbon stable isotope values are linked to catchments with low drainage soil and high cover of pasture land use. This is likely to be linked to high levels of methane‐derived carbon entering the stream food web.

Genetic and Ecological Divergence Between Northwest Atlantic Killer Whale Populations

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Killer whale (Orcinus orca) populations exhibit substantial genetic, ecological, and morphological differences across their global distribution. In this study, we use whole‐genome resequencing and compound‐specific stable isotope analysis of amino acids to show concurrent genetic and ecological differentiation in two relatively understudied killer ...

Body composition at 2 years of age in moderate and late preterm infants

open access: yesJournal of Pediatric Gastroenterology and Nutrition, Volume 82, Issue 5, Page 1288-1295, May 2026.
Abstract Objectives Moderate and late preterm infants (MLPTI, gestational age 32 0/7–36 6/7 weeks) have altered body composition compared to term‐born infants, but data beyond infancy are lacking. This study aimed to assess body composition at 2 years corrected age for prematurity (CA) in MLPTI, compare it to the literature on term‐born infants, and ...
