Probiotics' Benefits May Be More Than a Gut Feeling

Probiotics' Benefits May Be More Than a Gut Feeling | Longevity science | Scoop.it

Probiotics, believed to help with digestion, are increasingly being studied to treat wide-ranging conditions, from colic to cholesterol and the common cold.

 

One of the fastest-growing dietary supplements, probiotics are now prominent on drug and big-box store shelves. They are live microorganisms—or "good" bacteria—that when consumed in capsules or yogurt are said to confer a health benefit.

15 Health Benefits of Vitamin D, According to Science (+15 Best Vitamin D Foods) - Jen Reviews

15 Health Benefits of Vitamin D, According to Science (+15 Best Vitamin D Foods) - Jen Reviews | Longevity science | Scoop.it
Vitamin D, sometimes referred to as the “sunshine vitamin”, is a hormone-like, fat-soluble vitamin that your body produces when it is in direct contact with sunlight. Sunscreen however, important for protection from melanoma and rapid aging of the skin, blocks these rays. So while we do make it naturally, it is recommended to take supplements.

Vitamin D is vital to the intestinal absorption of many minerals and vitamins that we need to stay healthy and a lack of vitamin D can have dire consequences on our bones, immune system and heart health.

Harvard's tiny robot arm picks, packs and performs surgery on the micro scale

Harvard's tiny robot arm picks, packs and performs surgery on the micro scale | Longevity science | Scoop.it

Thanks to their speed and dexterity, Delta robots are commonly used on assembly lines, but they do need a lot of space to work in. Now, Harvard engineers have developed the world's smallest version of the ubiquitous bot, dubbed the MilliDelta. As its name suggests, the new robot measures just a few millimeters, and could lend a hand in precise picking, packing, manufacturing and even surgery on the micro scale.

In 2011, the team at Harvard's Wyss Institute developed a flatpack fabrication technique for tiny robots, which they call pop-up microelectromechanical systems (MEMS) manufacturing. Over the last few years, the researchers put the idea into action to make a self-assembling crawling robot, and the agile Robobee. The MilliDelta is the latest and smallest creation to be made using this approach, allowing the team to quickly iterate on the design until they reached the current, final version.

RNA-based decoy molecule suggests path to opioid-free pain control

RNA-based decoy molecule suggests path to opioid-free pain control | Longevity science | Scoop.it

Many modern opioid-based painkillers don't target the specific site of pain but instead interfere with the brain's sensation of that pain. It's not an especially efficient way to tackle pain and has resulted in widespread social problems stemming from the addictive quality of the drugs. A team of researchers has revealed a novel method for reducing our responsiveness to pain and it involves tricking our body's pain-signaling processes.

A great deal of research is currently underway to find effective and viable new techniques to control pain without resorting to addictive and psychoactive opioids.

Limiting dietary fat could help prevent prostate cancer’s fatal metastatic progression

Limiting dietary fat could help prevent prostate cancer’s fatal metastatic progression | Longevity science | Scoop.it

A team from the Cancer Center at Beth Israel Deaconess Medical Center (BIDMC) has been studying the mechanisms behind the metastatic progression of prostate cancer. They've found that a high-fat diet could play a major role in promoting metastasis of what is generally an "indolent" disease.

 

Indolent cancers are low-risk, slow-growing tumors that can progress so slowly that often no treatment is ever needed. Thyroid, lung and breast cancers can be classified as indolent, as can many cases of prostate cancer. The key thing for a physician trying to plan a treatment after a cancer has been identified is to understand what factors can cause it to metastasize and move to other parts of the body, often with fatal results.

Safety Communications > The FDA Warns that Biotin May Interfere with Lab Tests: FDA Safety Communication

Biotin in blood or other samples taken from patients who are ingesting high levels of biotin in dietary supplements can cause clinically significant incorrect lab test results. The FDA has seen an increase in the number of reported adverse events, including one death, related to biotin interference with lab tests.

Biotin in patient samples can cause falsely high or falsely low results, depending on the test. Incorrect test results may lead to inappropriate patient management or misdiagnosis.
Ray and Terry's 's insight:

Our products do not contain more than 100% RDA of biotin. The safety warning pertains to high levels of biotin in supplements.

Gene Therapy Had a Breakthrough 2017—2018 May Be Even Better

Gene Therapy Had a Breakthrough 2017—2018 May Be Even Better | Longevity science | Scoop.it
Gene therapy had a hell of a 2017. After decades of promises but failed deliveries, last year saw the field hitting a series of astonishing home runs.

The concept of gene therapy is elegant: like computer bugs, faulty letters in the human genome can be edited and replaced with healthy ones.

But despite early enthusiasm, the field has suffered one setback after another. At the turn of the century, the death of an 18-year-old patient with inherited liver disease after an experimental gene therapy treatment put the entire field into a deep freeze.

But no more. Last year marked the birth of gene therapy 2.0, in which the experimental dream finally became a clinical reality. Here’s how the tech grew into its explosive potential—and a sneak peek at what’s on the horizon for 2018.

The Future of Cancer Treatment Is Personalized and Collaborative

The Future of Cancer Treatment Is Personalized and Collaborative | Longevity science | Scoop.it
Just a few years ago, microscopes were the primary tool used in cancer diagnoses, but we’ve come a long way since.

“We still look at a microscope, we still look at what organ the cancer started in,” Wender said. “But increasingly we’re looking at the molecular signature. It’s not just the genomics, and it’s not just the genes. It’s also the cellular environment around that cancer. We’re now targeting our therapies to the mutations that are found in that particular cancer.”

Cancer treatments in the past have been largely reactionary, but they don’t need to be. Most cancer is genetic, which means that treatment can be preventative. This is one reason why newer cancer treatment techniques are searching for actionable targets in the specific gene before the cancer develops.

Does sunlight help us shed winter weight? | Longevity science | Scoop.it

A team of researchers at the University of Alberta in Canada has uncovered an extraordinary new, previously undiscovered, fat-burning mechanism. The new study reveals fat cells just under the skin are sensitive to a specific spectrum of sunlight and shrink when exposed.

As with many wonderful scientific discoveries, this new mechanism was unearthed completely by accident while the team of researchers was investigating ways to use light as a trigger to make fat cells produce insulin.

Anesthetics found to do more than simply induce sleep

Anesthetics found to do more than simply induce sleep | Longevity science | Scoop.it
Research over the last decade is suggesting that anesthetics result in unconsciousness by disrupting the brain's ability to communicate with itself. Blocking transmissions between different areas in the cortex seems to result in our consciousness vanishing. This also seems to result in strange side effects, such as memory loss and post-anesthesia cognitive impairment.

Wound monitoring app may keep patients out of hospitals | Longevity science | Scoop.it
According to recent studies, surgical site infections (SSIs) are the leading cause of hospital readmission following an operation. In hopes of catching those SSIs before readmission is necessary, scientists from the University of Wisconsin, Madison have developed an experimental app known as WoundCare.

In a test of the app, 40 vascular surgery patients were instructed to regularly upload photos of their wound sites to a server, along with answering a few onscreen questions regarding any symptoms they might be experiencing. They were instructed to do so daily for two weeks.

Engineered T-cell treatment helps keep cancer at bay

Engineered T-cell treatment helps keep cancer at bay | Longevity science | Scoop.it

Cancer has been winning the arms race agains the immune system for too long, but scientists are developing plenty of new weapons to try to turn the tide. One key technique is to supercharge T-cells – the foot-soldiers of the immune system – to better detect and kill tumors, and a new trial at the Children's Research Institute has delivered promising results, keeping cases of Hodgkin's lymphoma at bay for years at a time.

Normally, T-cells protect us from infection by patrolling the body, seeking out specific protein signatures that indicate invading bacteria, viruses or cancer cells, and then rallying more T-cells together to attack the threat. At least, that's how it would work in a perfect world. In our imperfect world, tumors have developed workarounds that ensure their survival.

Researchers Team Up with Patients to Build a Breast Cancer Database

Researchers Team Up with Patients to Build a Breast Cancer Database | Longevity science | Scoop.it

Last October, after a hectic couple of days campaigning for metastatic breast cancer awareness and research funding in Washington, D.C., Lisa Quinn boarded an RV owned by the advocacy group METAvivor for a road trip up the East Coast. The stay-at-home mom from northwest Arkansas was diagnosed with stage IV breast cancer in July 2015 at age 36, and in 2016, she had donated saliva and blood samples, along with her clinical data and information about her disease, to the Metastatic Breast Cancer Project (MBCproject).

Launched by the Broad Institute of MIT and Harvard University in October 2015, the MBCproject aimed to collect patient-donated samples from which to extract molecular and genomic information on metastatic breast cancer, pairing those data with clinical records and patient-reported information.

Tiny time-release beads target post-joint-replacement infections | Longevity science | Scoop.it
Ordinarily, people who are receiving new joints (such as hip implants) are placed on intravenous antibiotics before and after the operation. There might be a better method of reducing the chances of infection, however. A Houston Methodist orthopedic surgeon has created time-release antibiotic beads that are implanted with the joint.

"There is a risk of infection with any surgery, but infections after a joint replacement surgery are harder to treat," says Dr. Terry Clyburn, who developed the technology. "The metal implants are not connected to the body's bloodstream, so the white blood cells sent to fight the infection cannot reach the implant and kill the bacteria."

No sweat: The smart guide to exercise

No sweat: The smart guide to exercise | Longevity science | Scoop.it
Polls invariably cite the most common New Year's resolutions as focusing on diet, exercise and weight loss – which is perhaps unsurprising after the excess of the holidays.

But regardless of our good intentions, most resolutions are already broken come February. Some 39 per cent of adults in the UK fail to get enough exercise – despite gym membership hitting an all-time high in 2017 – and it’s a similar story in many other parts of the world. The price is more than vanity. Physical inactivity is thought to be responsible for 5 million deaths worldwide. So where are we going wrong?

We’re bombarded by specialist exercise advice and workouts that promise unrealistic results in record time, which can leave people feeling overwhelmed and doomed to fail. But if you strip down to the bare facts, things start to look a lot simpler. Just when your resolutions are most likely to crack, here's the no-nonsense guide to the exercise advice you really need to know.

How to grow functioning human muscles from stem cells | KurzweilAI

How to grow functioning human muscles from stem cells | KurzweilAI | Longevity science | Scoop.it
Biomedical engineers at Duke University have grown the first functioning human skeletal muscle from human induced pluripotent stem cells (iPSCs). (Pluripotent stem cells are important in regenerative medicine because they can generate any type of cell in the body and can propagate indefinitely; the induced version can be generated from adult cells instead of embryos.)

The engineers say the new technique is promising for cellular therapies, drug discovery, and studying rare diseases. “When a child’s muscles are already withering away from something like Duchenne muscular dystrophy, it would not be ethical to take muscle samples from them and do further damage,” explained Nenad Bursac, professor of biomedical engineering at Duke University and senior author of an open-access paper on the research published Tuesday, January 9, in Nature Communications.
