Wellness Resources - Mind Blog: The Keys to a Better Brain | Longevity science | Scoop.it

Growing older is not the same as aging. Everyone grows older all the time, but we aren’t necessarily aging as we do so since, by definition, the aging process is one of deterioration.

But we can actually grow new brain connections and even create new neurons from stem cells as a result of our thoughts. If you want to keep your brain and body healthy, you can start by adapting our suggestions into your personal plan.

The Summer 2017 issue of Conscious Lifestyle Magazine features Ray & Terry’s recommendations for building a better brain. As a Ray & Terry’s subscriber, we are happy to share the full article with you (pdf).

Tumor Organoids Predict How Well Patients Respond to Cancer Drugs | The Scientist Magazine®

Tumor Organoids Predict How Well Patients Respond to Cancer Drugs | The Scientist Magazine® | Longevity science | Scoop.it
For cancer patients with just months to live, time is short—too short to try drug after drug with the hope of finding one that slows the disease. But lab-grown mini tumors derived from patients’ cells could offer a way to test many drugs in parallel, saving time and possibly extending lifetimes. A report today (February 22) in Science brings this concept closer to clinical reality.

Previously, there has been “anecdotal evidence that observations in the clinic can be reproduced with organoids,” says stem cell and developmental biologist Hans Clevers of the Hubrecht Institute in Utrecht, the Netherlands, who was not involved in the research. “But, [the authors] have now for the first time come up with a large number of cases like that and have statistical [results] that are very impressive.”

They have “shown definitively that these organoids are predictive of response,” Clevers continues. “I’m sure this is going to be one of the key papers in this field.”

Excessive alcohol use strongly linked to early-onset dementia in massive study

Excessive alcohol use strongly linked to early-onset dementia in massive study | Longevity science | Scoop.it

A large-scale observational study of over one million adults has confidently linked chronic heavy alcohol consumption with early-onset dementia. The strong association confirms several recent similar studies examining the damaging effects of alcohol on the brain.

The massive study examined the records of all adult patients admitted to hospitals in metropolitan France over a five-year period. Some 1.1 million subjects were found to have been diagnosed with dementia in that time and over 57,000 of those cases were classified as early-onset, meaning they were displaying symptoms at ages younger than 65 years. Strikingly, 57 percent of those early-onset dementia cases were associated with an alcohol-use disorder defined as chronic alcohol use or alcohol dependence.

Cancer Vaccines May Overhaul Cancer Therapy in the Next Decade

Cancer Vaccines May Overhaul Cancer Therapy in the Next Decade | Longevity science | Scoop.it
The term “silver bullet” gets tossed around a lot, but cancer vaccines are just that. Unlike the flu vaccines that we’re familiar with, cancer vaccines are slightly different in that they don’t just seek to prevent cancers from forming. In many cases, these vaccines also treat tumors already within the body.

What unites cancer vaccines is this: these agents, ranging from chemicals to DNA-like molecules to cells, all give the immune system a boost so that it better recognizes and attacks cancer cells.

To Dr. Ronald Levy, an oncologist at Stanford University, cancer immunotherapy is the way to go. You may have heard of some of these treatments already. CAR-T, which genetically enhances a patient’s immune cells to better target cancers, was approved last year to treat certain types of blood cancers.

Common blood pressure medication could delay onset, or even prevent, type 1 diabetes

Common blood pressure medication could delay onset, or even prevent, type 1 diabetes | Longevity science | Scoop.it

New research into off-label uses for a 50-year-old drug commonly prescribed for high-blood pressure has found that it could prevent the onset of type 1 diabetes. The promising research also suggests a new approach for investigating drugs that could help treat a variety of autoimmune diseases.

Up to 60 percent of people at risk of developing type 1 diabetes possess a molecule dubbed DQ8. The new study, from researchers at the University of Colorado and the University of Florida, set out to investigate whether blocking that specific molecule could also block the onset of type 1 diabetes and whether there was an already approved drug that achieved this effect.

Past studies have revealed that when a woman develops ovarian cancer, her sister has a higher risk of also developing the disease than her mother. This was difficult to explain, but researchers at the Roswell Park Comprehensive Cancer Center have discovered that a newly identified mutation on the X-chromosome, passed down from the father, may be linked to an earlier onset of ovarian cancer in women and higher rates of prostate cancer in men.

Virtual Biobank revolutionizes access to human cancer tissues

Virtual Biobank revolutionizes access to human cancer tissues | Longevity science | Scoop.it

In a move that could revolutionize the development of new cancer treatments, researchers from the University of Newcastle and the Hunter Medical Research Institute (HMRI) have created the world's first virtual platform to host 3D copies of human cancer tissues.

Until now, tissue samples donated by patients have only been available on request from physical biobanks that are based locally. The process can take a few months for clearance and the samples are usually unable to be reused once examined. As a way of improving this scenario, a team led by Dr Jamie Flynn, Dr Antony Martin and Dr William Palmer has established The Virtual Biobank.

"Nano-factories" produce anti-cancer drugs from inside tumors

"Nano-factories" produce anti-cancer drugs from inside tumors | Longevity science | Scoop.it

Cancer cells thrive thanks to some robust defense mechanisms, so finding ways to get past them is a key area of research. In the past, scientists have sent gold nanoparticles inside tumors by hitchhiking on white blood cells, before heating the gold with near-infrared light to kill the cancer from within. Others examined the possibility of administering a "prodrug" that remained inactive until it detected cancer markers, and then began producing drugs from inside the tumor.

The new work follows a similar function as the latter. The Technion scientists loaded molecular machines inside lipid-based particles that resemble biological cell membranes, creating what they call "nano-factories." Once they're activated by sensing the presence of abnormal cells, these particles kick into gear, producing...
