Single-Cell Atlas Reveals the Hemocyte Subpopulations and Stress Responses in Asian Giant Softshell Turtle during Hibernation

Biology, 2023
Hibernation in turtle species is an adaptive survival strategy to colder winter conditions or food restrictions. However, the mechanisms underlying seasonal adaptions remain unclear.

Cold resistance of mammalian hibernators ∼ a matter of ferroptosis?

Frontiers in Physiology
Most mammals adapt thermal physiology around 37°C and large deviations from their range, as observed in severe hypothermia and hyperthermia, resulting in organ dysfunction and individual death. A prominent exception is mammalian hibernation.

Surgery for hibernation [PDF]

Heart, 2004
In the early 1980s Rahimtoola reviewed the results of coronary bypass surgery trials1 and identified patients with coronary artery disease and chronic left ventricular dysfunction that improved upon revascularisation. The results of medical treatment for ischaemic cardiomyopathy have been poor.

Mechanisms controlling mammalian hibernation [PDF]

, 1992
P(論文)Seasonal cold or long term cold exposure induces hibernation in certain species of mammals. Hibernation is a physiological state in which extreme but regulated reductions in body temperature, metabolic rate and other physiological systems occur. The

Comparison of brain transcriptome of the greater horseshoe bats (Rhinolophus ferrumequinum) in active and torpid episodes. [PDF]

PLoS ONE, 2014
Hibernation is an energy-saving strategy which is widely adopted by heterothermic mammals to survive in the harsh environment. The greater horseshoe bat (Rhinolophus ferrumequinum) can hibernate for a long period in the hibernation season.

Transgenic system for conditional induction and rescue of chronic myocardial hibernation provides insights into genomic programs of hibernation

, 2008
A key energy-saving adaptation to chronic hypoxia that enables cardiomyocytes to withstand severe ischemic insults is hibernation, i.e., a reversible arrest of contractile function.

EXAMINING HIBERNATION IN THE BIG BROWN BAT THROUGH DNA METHYLATION [PDF]

, 2021
Hibernation allows individuals to conserve energy during seasonal low temperatures. As the physiological regulation of hibernation is inadequately understood, I examine hibernation using DNA methylation (DNAm).

Dynamics in gut microbiota diversity, composition, and assembly reveal the adaptability of invasive snail Pomacea canaliculata during hibernation in rice fields

Frontiers in Microbiology
The gut microbiota plays a crucial role in host immunity and metabolism and may facilitate the adaptation of invasive species to new environments. During hibernation, gut microbial communities undergo compositional shifts to help hosts cope with low ...

Increased brain histamine H₃ receptor expression during hibernation in golden-mantled ground squirrels

BMC Neuroscience, 2003
Background Hibernation is a state of extremely reduced physiological functions and a deep depression of CNS activity. We have previously shown that the histamine levels increase in the brain during hibernation, as does the ratio between histamine and its

Psychological Hibernation in Antarctica [PDF]

Frontiers in Psychology, 2018
Human activity in Antarctica has increased sharply in recent years. In particular during the winter months, people are exposed to long periods of isolation and confinement and an extreme physical environment that poses risks to health, well-being and performance.
