Progress for heart disease!

For the first time, a new drug given along with a cholesterol-lowering statin medicine has proved able to shrink plaque that is clogging arteries, potentially giving a way to undo some of the damage of heart disease.

The difference was very small but doctors hope it will grow with longer treatment, and any reversal or stabilization of disease would be a win for patients and a long-sought goal.

The drug, Amgen Inc.’s Repatha, also drove LDL, or , down to levels rarely if ever seen in people before. Heart patients are told to aim for below 70, but some study participants got as low as 15.

I said over a year ago that if the US will not do it China will. Whilst there was talk about a moratorium on CRISPR in the US the Chinese were forging ahead and taking steps to become a world leader in biotech. Well here we are, they have deployed CRISPR in humans for cancer and this is only the start. As George Church advocates, we should have appropriate engineering safety measures in place but we should push ahead and do these things.

The move by Chinese scientists could spark a biomedical duel between China and the United States.

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.

The researchers chose mice as their target, feeding some groups water with spermidine mixed in, while other groups received plain water. After observing the rodents over the course of their lifespans, the researchers discovered that those who had been given spermidine lived longer than those who had not—even if the supplement was not given to them until middle age. Closer examination of the rodents revealed that those given the supplement also had better heart function and lower . They also found that rats fed a high-salt diet, which causes , had lower pressure readings when given spermidine.

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!

Why support the SENS Research Foundation, and their ally the Methuselah Foundation? Because these organizations have proven capable of using your charitable donations more effectively than any other in order to make significant progress towards an end to aging and age-related disease. For fifteen years now, the principals and their network of advocates and scientists have nudged, debated, and funded researchers to ensure that the broader research community builds the basis for human rejuvenation. Aging is an accumulation of molecular damage, and if that damage is repaired sufficiently well, a goal that modern medicine is only just starting to grapple with despite decades of evidence, then the result will be a halt to the processes of degenerative aging. An end to the disease, dysfunction, and suffering of aging.

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.

Tmem135 has previously been associated with fat storage and long life in the roundworm Caenorhabditis elegans, but its molecular function has never been characterized clearly. The new study shows that irregular levels of the protein lead to symptoms of a common age-related retinal disease called macular degeneration.

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.

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…
