Spermidine found to lengthen lifespan in mice and to promote cardiovascular health

Posted by in categories: biotech/medical, health

Fancy a bit of cheese?


(Medical Xpress)—A large team of researchers with members from several Europeans countries and the U.S. has found that mice fed a compound called spermidine lived longer than ordinary mice and also had better cardiovascular heath. In their paper published in the journal Nature Medicine, the researchers describe experiments they carried out with the compound and mice, what they found and why they believe the compound might provide benefits for humans.

Prior research has found that ingestion of spermidine—which was first discovered in semen samples, hence its name—led to longer lifespans in simple organisms such as fruit flies, yeast and roundworms. In this new study, the researchers sought to find out if the same would prove true for more complex creatures.

Forever Healthy Foundation Provides a $150,000 Challenge Fund to Match SENS Rejuvenation Research Donations

Posted by in categories: biotech/medical, life extension

More news about SENS Research Foundation fundraiser and a look back at some of the achievements so far.

#sens #aging


Good news! Thanks to the generous pledges of new SENS Patrons, signing up for monthly donations to the SENS Research Foundation over the past two weeks since the fundraiser started, the $24,000 matching fund put up by Josh Triplett and Fight Aging! is nearly met. Just a little more left to reach the target: if you are the next person to sign up, the next year of your donations to the SENS Research Foundation will be matched dollar for dollar. But if you miss out on that, donations made before the end of the year can still be matched. The Forever Healthy Foundation’s Michael Greve, who earlier this year pledged $10 million to SENS rejuvenation research and startup companies building rejuvenation therapies, has put up a further $150,000 challenge fund. He will match all donations to the SENS Research Foundation made before the end of 2016, and there is still a way to go in order to meet that target. So help us get this done!

New protein provides critical link between aging and age-dependent disease

Posted by in categories: biotech/medical, life extension

New hope for age related macular degeneration.


The discovery of a novel protein that links aging and age-dependent retinal diseases could lead to potential new treatments for conditions that cause sight loss in later life.

In a study in mice, to be published in the journal eLife, researchers from the University of Wisconsin-Madison reveal that Transmembrane 135 (Tmem135) regulates retinal aging, and that mutations in the protein result in age-dependent disease.

Measuring the Effects of Prevention on Heart Disease

Posted by in categories: biotech/medical, health, life extension

Heart disease prevention measures have made some impact on mortality rates. Looking after your heart is absolutely critical for your longevity plan.


Despite the rising proportion of the older population who choose to be overweight or obese, risk of heart disease has declined somewhat in past few decades. This outcome can be attributed to prevention in the sense of at least some people taking better care of their health by specifically targeting measures such as blood pressure and blood lipid levels, coupled with prevention in the sense of treatments such as statins that also reliably influence these measures. Increased blood pressure with age, or hypertension, directly impacts risk of cardiovascular disease and other conditions by putting additional stress on tissue structures and causing the heart to remodel itself detrimentally. Higher blood lipid levels on the other hand contribute to the progression of atherosclerosis, attacking blood vessel walls to form fatty deposits that can later break to cause blockages or ruptures of blood vessels. These are all things best avoided if possible, but until the advent of rejuvenation therapies after the SENS model the best that can be done is to slow down the damage.

The Future of Surgery Is Robotic, Data-Driven, and Artificially Intelligent

Posted by in categories: biotech/medical, robotics/AI

As far back as 3,500 years ago ancient Egyptian doctors were performing invasive surgeries. Even though our tools and knowledge have improved drastically over time, until very recently surgery was still a manual task for human hands.

When it came out about 15 years ago, Intuitive Surgical’s da Vinci surgical robot was a major innovation. The da Vinci robot helps surgeons be more precise and dexterous and to remove natural hand tremors during surgery.

In the years since da Vinci first came out, many other surgical robots have arrived. And today there’s a new generation coming online, like the Verb robot, a joint venture between Google and Johnson and Johnson. This means surgery is about to get even more interesting. Surgical robotics will be able to do more than just improve dexterity and reduce incision size…

Can your own immune system kill cancer?

Posted by in category: biotech/medical

It definitely can.


NEW YORK (CNN) — There was another big win in the advancement of immunotherapy treatments for cancer this week.

The Food and Drug Administration approved an immunotherapy drug called Keytruda, which stimulates the body’s immune system, for the first-line treatment of patients with metastatic non-small-cell lung cancer.

An Age-Associated Decline in Thymic Output Differs in Dog Breeds According to Their Longevity

Posted by in categories: biotech/medical, life extension

Immune system decline one of the hallmarks of aging and something that we should be concerned about addressing.


The age associated decline in immune function is preceded in mammals by a reduction in thymic output. Furthermore, there is increasing evidence of a link between immune competence and lifespan. One approach to determining thymic output is to quantify signal joint T cell receptor excision circles (sj-TRECs), a method which has been developed and used in several mammalian species. Life expectancy and the rate of aging vary in dogs depending upon their breed. In this study, we quantified sj-TRECs in blood samples from dogs of selected breeds to determine whether there was a relationship between longevity and thymic output. In Labrador retrievers, a breed with a median expected lifespan of 11 years, there was an age-associated decline in sj-TREC values, with the greatest decline occurring before 5 years of age, but with sj-TREC still detectable in some geriatric animals, over 13 years of age. In large short-lived breeds (Burnese mountain dogs, Great Danes and Dogue de Bordeaux), the decline in sj-TREC values began earlier in life, compared with small long-lived breeds (Jack Russell terriers and Yorkshire terriers), and the presence of animals with undetectable sj-TRECs occurred at a younger age in the short-lived breeds. The study findings suggest that age-associated changes in canine sj-TRECs are related to breed differences in longevity, and this research highlights the use of dogs as a potential model of immunosenescence.

Scientists develop world’s first light-seeking synthetic nanorobot

Posted by in categories: biotech/medical, engineering, nanotechnology, robotics/AI

With bots the size of a single blood cell, this could spur a huge leap in the field of non-invasive surgeries.

Scientists have developed the world’s first light-seeking synthetic nanorobot which may help surgeons remove tumours and enable more precise engineering of targeted medications.

It has been a dream in science fiction for decades that tiny robots can fundamentally change our daily life. The famous science fiction movie “Fantastic Voyage” is a very good example, with a group of scientists driving their miniaturised Nano-submarine inside human body to repair a damaged brain.
