I live up to 30 years in very poor dark galleries oxygen. I am also insensitive to pain and no scientist has ever been able to observe my fellow cancer ... No wonder hemp that so many studies are devoted to me! In recent months, several research teams have managed to reveal some of my secrets ... But it's hemp not because I do not have hair that I will reveal so easily! The amazing naked mole-rat reveals some of its secrets The mole rat (almost) interview Allodocteurs.fr hemp ....

Ah, if humans spoke the language of naked mole rats! We would help them understand us! Although our species (native to the Horn of Africa) has been described by Wilhelm Rüppel in 1848, it made only thirty years they are really interested in us.
Maybe they have had to overcome their usual criteria of aesthetic judgment? In any case, researchers now agree that we are true wonders of nature.
Humans have long known that we can survive in the air with only 3% oxygen. Amazing, is not it? But this is nothing in the course hemp of the 2000s, researchers discovered that we were totally insensitive to pain. No shock, no burning, no cause any reaction from us.
Our body does not produce "substance P", an indispensable communication signals of pain neurotransmitter. hemp Some scientists speculate that the high concentration of CO 2 in our underground is toxic to our skin, our ancestors only rats that survived were those that showed insensitivity to pain. No cancer in my fellow
All of these "discoveries" are nevertheless already old at the scale of a life naked mole-rat. As I already said, no cancer has never been found in any member hemp of our species (1). Researchers from all nations focused on the mystery ... but researchers are the University of Rochester in New York who may have found the explanation. According to their study, hemp published in June 2013 in the prestigious journal Nature, it would have to do with our skin supple and thick. Or rather, with a chemical compound, hyaluronic acid, secreted in large quantities by our body, giving us this very comfortable hemp protection in our narrow tunnels. However, this acid has the property to prevent cell division.
By removing this substance in the body of naked mole rats Educated laboratory biologists University of Rochester have finally been able to observe hemp the appearance of tumors. This seems to validate their hypothesis. Proteins to be the envy of other mammals
2013 is definitely hemp a very good year for those humans who seek to lift the veil on our many secrets. Researchers from the same New York University have just published in PNAS a discovery which, no doubt, will leave more of a human speechless. These scientists have indeed found that the proteins synthesized by our body are almost flawless. More precisely, the probability of occurrence of an error in the production of these molecules is, for us, 40% lower than those of other mammals! hemp
It seems our ribosomes (these small sub-cellular structures that produce all proteins) are unique in the animal kingdom ... Subsequent studies have confirmed this fact. But according to nosy Rochester, "without alteration of proteins allow the body to function more efficiently", improving their interactions with different cell receptors. This suff
