This study shows HIF-1α and HIF-2α differentially regulate lung alveolar macrophage function, with HIF-2α playing a central role in impaired maturation and surfactant clearance.

This paper investigates how piperine affects resting thick filament activation and dynamic contractility in fast and slow rat skeletal muscles, finding fiber-type-dependent enhancements in contractile function.

This study evaluates a water-soluble Passiflora incarnata formulation's effect on sperm motility, finding it reduces motility without affecting viability, suggesting potential as a non-hormonal contraceptive.

This study shows that loss of CEACAM2 in mice impairs renal insulin clearance, leading to hyperinsulinemia, insulin resistance, and kidney dysfunction.

This study examines how KCNC1 gene polymorphisms affect blood lipid levels and response to high-intensity interval training in young Han Chinese individuals, finding sex-specific associations.

This study profiles systemic immune changes in a murine OA model, finding reduced MHCII on macrophages and DCs, increased tolerogenic DCs, and shifts in T cell composition.

This study shows that increased plasma viscosity affects endothelial and mural cell activity in capillaries, impairing flow dynamics and perfusion.

This study investigates how different photoperiods affect cotton growth and development by integrating physiological measurements and transcriptomics, revealing gene expression changes and regulatory pathways involved.

This paper shows that injecting a cobalt oxide time-release ion matrix (CoO-TRIM) accelerates skeletal muscle regeneration in injured mice without affecting healthy muscle.

This study quantifies seasonal plasticity in coral physiology and symbiont communities across three genera, revealing differences in stress resilience linked to environmental factors and genetic diversity.

This study shows that DENND5B is critical for dietary triglyceride absorption and that its deletion reduces body fat and increases intestinal fatty acid oxidation via autophagy in both sexes.

This study examines how umbilical cord structure affects heat transfer in mammals, finding that cord morphology influences fetal thermal resilience.

The paper identifies a biphasic gene regulatory network in rat pituitary gonadotropes that controls the preovulatory hormone surge, showing FSH surge is driven by dynamic Fshb transcription rather than Lhb upregulation.

This study shows that intermittent fasting improves systemic metabolism regardless of ketogenesis but has sex-specific hepatic benefits requiring ketogenesis in mice.

This study uses BOLD-fMRI to map real-time spatial and temporal changes in brain activity induced by transcranial photobiomodulation in healthy humans.

This paper compares high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on VO2max and microvascular adaptations, finding HIIT leads to greater VO2max improvement and distinct structural changes without angiogenesis.

This study links canine temperament scores to salivary cortisol and serotonin levels, showing negative correlations between cortisol and temperament scores, and positive associations between serotonin and higher scores.

This study shows Drosophila and their gut bacteria exchange pantothenate for nitrogen, reprogramming fly metabolism and supporting bacterial growth.

This study identifies chondroitin sulfate as a potential therapeutic target for type 2 diabetes through genetic and preclinical evidence showing its effects on glycemic control and insulin action.

This study examines postoperative platelet count changes in dogs after mitral valve repair and identifies associated factors.
