Suspended animation: the molecular basis of metabolic depression
STOREY, K. B. 1988. Suspended animation: the molecular basis of metabolic depression. Can. J. Zool. 66: 124 132. An impressive array of organisms is capable of radically depressing basal metabolic rate and entering a hypometabolic state characterized by a marked reduction of many normal physiological functions. Environmental cues are often the trigger: low oxygen, low temperature, or lack of wa...

متن کاملIs hydrogen sulfide-induced suspended animation general anesthesia?
Hydrogen sulfide (H(2)S) depresses mitochondrial function and thereby metabolic rates in mice, purportedly resulting in a state of "suspended animation." Volatile anesthetics also depress mitochondrial function, an effect that may contribute to their anesthetic properties. In this study, we ask whether H(2)S has general anesthetic properties, and by extension, whether mitochondrial effects unde...
متن کاملNitric oxide-induced suspended animation promotes survival during hypoxia.
Oxygen plays a key role in energy metabolism. However, there are organisms that survive severe shortfalls in oxygen. Drosophila embryos rapidly arrest development upon severe hypoxia and recover upon restoration of oxygen, even days later. Stabilization of the normally unstable engrailed RNA and protein preserved the localized striped pattern of this embryonic patterning gene during 3 days in h...
متن کاملH2S induces a suspended animation-like state in mice.
Mammals normally maintain their core body temperature (CBT) despite changes in environmental temperature. Exceptions to this norm include suspended animation-like states such as hibernation, torpor, and estivation. These states are all characterized by marked decreases in metabolic rate, followed by a loss of homeothermic control in which the animal's CBT approaches that of the environment. We ...
