Sconfiggere la vecchiaia, quando?

(Medical Xpress) -- Is it possible that your child could live to see 150 years of age? What about your grandchild living to see their 1000th birthday? According to a British biomedical gerontologist and chief scientist of the Strategies for Engineered Negligible Senescence (SENS) Foundation Aubrey De Grey, that is a definite possibility.

De Grey believes that we are within 25 years of finding the medical technology to essentially bring a ‘cure’ to aging. He says the first person to live to see 150 is already alive and that the individual who will first live to see 1,000 years could be born within the next two decades.

He believes that with the advancement of medical treatments in areas such as gene therapy, stem cells, therapy, immune stimulation and a variety of other medical techniques, people will soon be able to just visit their physician for regular maintenance checkups and cures for diseases that are a part of aging will no longer be an issue.

While De Grey’s predictions may seem a bit extreme, life expectancy is growing by three months every year and many experts are predicting over a million centenarians by 2030. In 2010, Japan alone had over 44,000 residents who had passed the 100 year mark.

In 2005 a group of scientists dismissed his work as ‘pseudo-science’ and the Massachusetts Institute of Technology (MIT) Technology Review journal offered $20,000 to any molecular biologist who was able to show that De Grey’s theory was wrong. This reward has yet to be claimed.

Heart disease is caused by what De Grey refers to as “molecular garbage” that accumulates when the body ages and can no longer ‘take out the trash.’ De Grey is currently looking at identifying particular enzymes that can break down this garbage with the idea of being able to develop a type of genetic therapy to increase longevity.

De Grey defines aging as a lifelong accumulation of cellular and molecular damage and believes that with medical technology, the practice of preventative geriatrics will enable physicians to repair this damage before it becomes a problem and extend the healthy age and life of individuals.

(Medical Xpress) -- E' possibile che i tuoi figli possano vivere fino a raggiungere l'età di 150 anni? Ed i tuoi nipoti arrivare al loro millesimo compleanno? Secondo un gereontologo biomedico e chief scientist del Strategies for Engineered Negligible Senescence (SENS) Foundation, Aubrey De Grey, questa è una possibilità concreta.

De Grey crede che entro 25 anni avremo trovato la tecnologia medica per curare l'invecchiamento. Egli dice che la prima persona a vedere i 150 è già in circolazione e l'individuo che per primo vivrà fino a 1,000 anni potrebbe nascere entro il prossimo ventennio.

Egli crede che con l'avanzamento dei trattamenti medici in aree come la terapia genica, quella attraverso le cellule staminali, la stimolazione del sistema immunitario e una varietà di altre tecniche mediche, le persone saranno presto nella condizione di visitare il loro medico per un regolare check up di manutenzione e per la cura di malattie che sono legate all'invecchiamento.

Mentre le predizioni di De Grey possono sembrare un poco estreme la speranza di vista sta crescendo di tre mesi ogni anno e molti esperti predicono oltre un milione di centenari al 2030. Nel 2010, solo il Giappone ha avuto 44,000 residenti con oltre cento anni.

Nel 2005 un gruppo di scienziati ha respinto il suo lavoro come 'pseudoscientifico' e la rivista MIT Tech Review ha offerto $20,000 al biologo molecolare in grado di dimostrare la scorrettezza della teoria di De Grey. Il premio non è stato ancora rivendicato.

Le malattie cardiache sono causate da quella che De Grey chiama "spazzatura molecolare" che si accumula quando il corpo invecchia e non può più 'sbarazzarsi della spazzatura'. De Grey sta attualmente cercando di identificare particolari enzimi che possono sbarazzarsi della spazzatura con la speranza di essere in grado di sviluppare una terapia genetica per accrescere la longevità.

L'articolo non dice un cazzo ma sono interessanti l'argomento ed i commenti sul sito.

Wow. Just wow. Not at the prospect of living to 150 or 1000 years. Just how uninformed some of the posted comments are. So it's a "hardcore" fact that we already have the knowledge and technology to live that long? Really, I thought a fact was something that has been shown to be true, not just a wild extrapolation based on some popular media reports of science. As a cancer biology researcher, I can assure you that things get really really really really really complicated at that level. We don't even have a cure for cancer, or HIV, and people are CERTAIN that we'll cure aging in a couple years? No, and especially not now that they are reducing basic science funding. There is way too much hype here and no substance. Perhaps someone will live to 150 this century, but it will most certainly be a billionaire and they won't have a mind, so if you call that living, then yeah, go for it.

This branch of science is still in it's infancy. It was only in the 1890's that they had figured out how to boil amino acids apart. It was in the 1960-70's that it had figured out the helix dna configuration. In the 1990's they said that it would take 1000 years to figure out the gene sequencing and now they can figure out several a day....It will be sooner than later that we will be living longer, the time line of discoveries are already compressing.

In 1993, I was a broadcaster on the air in Calgary, AB.

I was 24 and I remember scientists speaking on this subject. There were two main camps of thought as I recall.
The one camp believed we were capable of extending life by 150-500 years, the other camp believed that number was actually indefinate...both camps believed we were 5-15 years away from that technology.

I've been expecting this since. During this time, I've kept to exercise, good diet...trying to keep myself a good candidate.

I'm now 43 but I'm still playing football, hockey and anything else I like.

So I guess if the technology isn't available to me in my life...I still haven't wasted a year of what I've been naturally given.
