Surgery for hibernation.
I n the early 1980s Rahimtoola reviewed the results of coronary bypass surgery trials 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. Coronary artery bypass grafting provides superior long term survival, but may be associated with a hi...
متن کاملHibernation
Hibernation (multiday torpor) and daily torpor in heterothermic mammals and birds are characterized by pronounced temporal reductions in body temperature, energy expenditure, water loss, and other physiological functions and are the most effective means for energy conservation available to endotherms. Hibernators express multiday torpor predominately throughout winter, which substantially enhan...
متن کاملChanges in gut function during hibernation: implications for bowel transplantation and surgery.
Organ transplantation has become routine in many centres throughout the world. Although success rates for intestinal transplantation are generally lower than for other organs, it is still high enough to warrant this form of therapy for patients with short bowel syndrome or other untreatable bowel diseases. Much of the success in transplantation is due to the impact of immunosuppressive drugs as...
متن کاملHibernation: Endotherms
The main function of hibernation and daily torpor in heterothermic mammals and birds (i.e. species capable of expressing torpor) is to conserve energy and water and thus to survive during adverse environmental conditions or periods of food shortage no matter if they live in the arctic or the tropics. However, the reduced energy requirements also permit survival of bad weather during reproductio...
متن کاملHibernation: poikilotherms
Introduction For cold-blooded or poikilothermic animals, winter presents challenges to survival. Since the body temperature (Tb) of poikilotherms is usually very close to that of their surrounding environment, the risk of death from freezing is very real when temperatures drop below 0°C. Food is also scare during the winter and some animals also have limited mobility because the cold can make m...
