hibernation
- Activation of respiratory muscles does not occur during cold-submergence in bullfrogs, Lithobates catesbeianus
Summary: Persistent neuromotor activity of respiratory muscles in bullfrogs during aquatic overwintering is unlikely to underlie normal respiratory motor function after months without lung breathing, despite having respiratory mechanics that operate underwater.
- Blood clotting behavior is innately modulated in Ursus americanus during early and late denning relative to summer months
Summary: Features of the blood clotting cascade of black bears provide novel insights into the underlying mechanisms they evoke for embolic protection during hibernation.
- Prevention of muscle wasting and osteoporosis: the value of examining novel animal models
Summary: Understanding the biology of animals that experience natural periods of disuse but suffer little musculoskeletal atrophy may reveal novel regulatory factors and lead to new therapeutics.
- Winter metabolic depression does not change arterial baroreflex control of heart rate in the tegu lizard Salvator merianae
Summary: Winter acclimation is compatible with lower resting heart rate but unchanged baroreflex sensitivity in the lizard Salvator merianae; independent of acclimation, heart rate responds more to hypotension than to hypertension.
- Insight into post-transcriptional gene regulation: stress-responsive microRNAs and their role in the environmental stress survival of tolerant animals
Summary: Overview of transcriptome regulation by microRNA and its involvement in the coordination of stress survival.
