Study suggesting that cellular and tissue function can be reactivates in pigs after death
Without oxygen, mammalian cells die. Paradoxically, restoring oxygen to cells that have been deprived of it also causes stress and damage — a phenomenon called reperfusion or reoxygenation injury. For decades, scientists have been searching for strategies to protect cells and organs against the detrimental effects of oxygen deprivation and reintroduction that can occur following stroke, heart attack or the cessation of breathing. Writing in Nature, Andrijevic et al. describe a system called OrganEx that enables oxygen to be recirculated throughout a pig’s body, preserving cells and organs an hour after a cardiac arrest.
Prof Martin Monti, Professor of Cognitive Psychology, University of California Los Angeles (UCLA), said:
“Biological death is more like a cascade of dominoes, with one event triggering the next, than an instantaneous transition. What is ground-breaking about this technology is that this cascade can be halted in some organs if only the right cellular environment and metabolic parameters can be restored. The potential implications, if this will ever be successfully translated to humans, are huge: how many more lives could be saved through transplantation each year thanks to greater organ viability?
Dr Anders Sandberg, Senior Research Fellow at the Future of Humanity Institute, University of Oxford, said:
“When blood circulation stops, cells begin to die due to lack of oxygen, and chemical changes begin that harm tissues and organ function. At normal temperature, irreversible changes set in after a few minutes. What this paper shows is that significant improvements are possible in how long after death preservation methods to keep organs alive can be started (up to an hour), and that some of the cellular damage can be partially reversed.
In the current study, Andrijevic et al. optimized this perfusate for whole-body reperfusion, altering the cryoprotective agents and antibiotics it contained, among other changes. They pumped their perfusate through the body using a computer-controlled system that involved a perfusion pump, an oxygenator and a haemodialysis unit, which maintains stable levels of electrolytes and other essential molecules in the perfusate.
10 ways to sleep better in unbearable heat
Is the mid year heat making it hard to get some rest?

A warm shower will increment blood stream to your skin and increment heat misfortune from your body. Then you can slip between the sheets feeling spotless and agreeable.
6. Rest on ice
Ice, truly? Indeed! In the event that you're battling with heat, snatch an ice pack from the cooler, enclose it by a tea towel and spot it in the bed any place it feels great. Or on the other hand recover your high temp water bottle. Fill it with water and pop it in the cooler for a bed-accommodating arrangement.
For more moment help, put an ice pack on the beat focuses on your wrists, neck, elbows, crotch, lower legs and, surprisingly, behind your knees. The virus will travel rapidly around your body, and you'll see the distinction very quickly. Simply don't get excessively cold!
