This study examines the role of both parasympathetic and sympathetic arousal in threat conditioning, showing that parasympathetic responses are linked to anxiety resilience and that ignoring them can misclassify individuals as non-learners.

This study investigates the role of the SLO2.1/NALCN complex in regulating mouse myometrial smooth muscle cell membrane potential across pregnancy, finding its activity decreases as pregnancy progresses.

The paper compares the olfactory performance of pectinate and filiform antennae in Lepidoptera, finding that pectinate antennae are more efficient at capturing odor at most speeds, while filiform are more energy-efficient at low speeds.

This study measures hemoglobin fractional synthetic rate in trained and untrained humans using 2H2O and finds no difference between trained and untrained individuals or between males and females.

This study examines how emojis affect autonomic responses, finding increased sympathetic activity and decreased parasympathetic activity in both males and females during an emotional task.

This study develops a PET-based method to track nitrogen gas movement in vivo and ex vivo using 13N2, showing its distribution in organs after inhalation.

This study shows that peripheral opioid receptor antagonism can reverse fentanyl-induced respiratory depression without causing aversive behaviors.

This study examines the effect of exercise frequency on aortic calcification in hyperlipidemic mice, finding that 5 days/week low-speed treadmill exercise reduces 18F-NaF uptake and cardiac remodeling.

This study shows that housing temperature affects molecular and systemic responses to cancer in mice, influencing metabolic adaptations and cytokine levels.

This study shows that endurance exercise increases plasma mature BDNF (mBDNF) in children, adolescents, and adults, with a greater response in adults, and that regular vigorous activity in youth correlates with higher basal mBDNF levels.

This study simulates how different motor unit pool models affect force generation in muscles during static and dynamic tasks, finding that feedback improves performance, especially for physiologically relevant models.

This study examines how low light affects cigar tobacco leaf morphology, growth rates, and gene expression, revealing hormonal and cellular changes in leaf structure.

This study investigates if haptic augmentation improves bimanual finger response times in middle-aged adults, finding performance gains but not in younger adults.

This study shows that oxidative injury to mitochondrial DNA contributes to acute and chronic lung injury, and that targeting OGG1 can mitigate this damage.

ABRpresto automatically estimates ABR thresholds using resampled cross-correlation across subaverages, achieving 92% accuracy within ±10 dB of human ratings on mouse data.

This study shows that female C57BL/6J mice exhibit reproductive seasonality in controlled lab conditions, mirroring external seasonal patterns.

The paper tests a neural simulator, Tau-20 version 2, to safely deliver high-frequency stimulation for identifying ganglionated plexuses in atrial fibrillation treatment without causing cardiac damage.

This study shows that reducing prothrombin levels protects podocytes and decreases proteinuria in a rat model of glomerular disease.
