Scientists use stem cells to grow new human hair in the lab | KurzweilAI

Scientists use stem cells to grow new human hair in the lab | KurzweilAI | Longevity science | Scoop.it
A method for initiating human hair growth — using human pluripotent stem cells to create new cells — has been developed by Sanford-Burnham Medical Research Institute (Sanford-Burnham) researchers.

Their idea is to coax human pluripotent stem cells to become dermal papilla cells — a unique population of cells that regulate hair-follicle formation and growth cycle. (Human dermal papilla cells on their own are not suitable for hair transplants because they cannot be obtained in necessary amounts and rapidly lose their ability to induce hair-follicle formation in culture, the researchers explain.)

Targeting immune cell halts type 1 diabetes development in mice

Targeting immune cell halts type 1 diabetes development in mice | Longevity science | Scoop.it
Scientists working at St Louis University (SLU) have demonstrated the ability to prevent type 1 diabetes in mice by focusing on a particular immune cell whose properties weren't entirely clear. They discovered that impeding the development of this cell they could in fact stop the onset of the disease.

The lack of insulin production that defines type 1 diabetes and makes blood-sugar levels difficult to manage is driven by the body's immune system. A couple of culprits are already known to scientists in the form of two "T-cells", which have a hand in the demise of the pancreatic beta cells that produce insulin.

First contracting human muscle ever grown in laboratory

First contracting human muscle ever grown in laboratory | Longevity science | Scoop.it
Researchers working at Duke University’s Pratt School of Engineering claim to have produced a laboratory first by having grown human muscle tissue that contracts and reacts to stimuli. Electrical pulses, biochemical signals and pharmaceuticals have all been used to produce reactions in the tissue that show it behaves in the same way that natural human muscles does. As a result, laboratory grown tissue may soon provide researchers with the ability to study diseases and assess drugs without invasive procedures on human subjects.

‘Glowing’ nanotech guides cancer surgery, kills remaining cancer cells | KurzweilAI | Longevity science | Scoop.it
Oregon State University researchers have developed a new way to selectively insert compounds into cancer cells — a system that will help surgeons identify malignant tissues and then, in combination with phototherapy, kill any remaining cancer cells after a tumor is removed.

The method should allow more accurate surgical removal of solid tumors at the same time it eradicates any remaining cancer cells. In laboratory tests, it completely prevented cancer recurrence after phototherapy.

Man-made ligament could replace ruptured ACLs

Man-made ligament could replace ruptured ACLs | Longevity science | Scoop.it
According to professor of biomedical engineering Guillermo Ameer, who is leading the project, the use of patellar tendon grafts often results in knee discomfort that never goes away. This isn't surprising, as the procedure involves removing part of the existing patellar tendon to take the place of the ACL – in fact, what's left of the patellar tendon can subsequently end up rupturing, too.

That's where his team's engineered ACL comes in. Its main body is made from braided polyester fibers, with a tensile strength similar to that of the natural ligament. At either end of it, however, those fibers are blended into a mixture of a porous antioxidant biomaterial developed previously in his lab, and hydroxyapatite (a form of calcium) nanocrystals – these occur naturally in bones and teeth.

New approach could lead cancer cells down path of destruction

New approach could lead cancer cells down path of destruction | Longevity science | Scoop.it
Scientists from Case Western Reserve University's School of Medicine have discovered a potential treatment that may steer cancer cells toward their own destruction. The study focused on a particular gene that was found to influence levels of a tumor-fighting protein called 53BP1, the heightened presence of which makes cancer cells more vulnerable to existing forms of treatment.

The proposed therapeutic approach centers on the repairing of DNA, a process that sees the body mend molecules damaged by everything from reactive oxygen components to radiation and chemical agents. More specifically, it focuses on a double-strand break, a type of injury that sees both strands of the double helix severed, leading to damaged and dead cells.

U.S. cancer deaths fell 22 percent since 1991

More than 1.5 million Americans avoided death from cancer since 1991 thanks to falling smoking rates and better cancer prevention, detection and treatments, according to a study from the American Cancer Society.

The overall rate of deaths from cancer decreased from about 215 per 100,000 people in 1991 to about 169 per 100,000 people in 2011, researchers found.

Scientists extend telomeres to slow cell aging | KurzweilAI | Longevity science | Scoop.it
Scientists at the Stanford University School of Medicine have developed a new procedure that uses modified messenger RNA to quickly and efficiently increase the length of human telomeres, the protective caps on the ends of chromosomes that are associated with aging and disease.

Treated cells behave as if they are much younger than untreated cells, multiplying with abandon in the laboratory dish rather than stagnating or dying. Skin cells with telomeres lengthened by the procedure were able to divide up to 40 more times than untreated cells.

New sensor may allow for better long-term monitoring of patients' vitals

New sensor may allow for better long-term monitoring of patients' vitals | Longevity science | Scoop.it
Researchers have developed a new silver nanowire sensor that has the potential to significantly improve long-term patient health monitoring. The new sensor is as accurate as those used in hospitals, and thanks to its dry nature and flexibility, is well suited to electrophysiological monitoring when the patient is moving around.

With existing hospital-based electrophysiological sensors, such as EKGs, a layer of electrolytic gel must be maintained between the sensor and patient’s skin in order for accurate recordings to be obtained. This wet electrode method provides accurate results, but lacks practicality, as the gel must be reapplied to keep it from drying up. If this occurs, the sensor will be less effective at reporting stats and may cause discomfort to the patient.

Microcapsule delivery method opens door for protein to treat osteoarthritis

Microcapsule delivery method opens door for protein to treat osteoarthritis | Longevity science | Scoop.it
Although known to reduce inflammation and aid in the repair of damaged tissue, the protein molecule called C-type natriuretic peptide (CNP) could not previously be put to use in treating osteoarthritis as it breaks down easily in the body. But now researchers at Queen Mary University of London (QMUL) could make this possible by using slow-release microcapsules containing the protein.

CNP, which occurs naturally in the body, being produced by the endothelium and the heart, is believed to play a major role in vascular and cardiac function. Although it reduces inflammation and aids in the repair of damaged tissue, it could not perform these functions in the treatment of osteoarthritis, even if injected into the cartilage tissue, because it breaks down before it can reach the site of the damage.

Pre-surgical tests using 3D printed models is proving itself to be one of the most critical medical applications of 3D printing, 3D scanning and 3D software. When all of these tools are used together in one process in medical settings, the results have been overwhelmingly positive for both patients and surgeons. There are some applications that occupy “pivot” zones, where we can expect to see them used similarly in a variety of different ways. What those pivot zones are, we will have to wait and see.

Exercise improves your ‘healthspan,’ but why that is remains a mystery

Exercise improves your ‘healthspan,’ but why that is remains a mystery | Longevity science | Scoop.it
It has become increasingly clear that exercising into old age is one of the best -- if not the best -- thing you can do to grow old successfully. By this, researchers mean aging with the fewest number of infirmities and the least deterioration of physiological function. There's even a word for it: exercise (and other efforts such as quitting smoking) improves your "healthspan," the number of years you are able to live in good health. Which, as we know, is not keeping up with average life expectancy for much of the developed world's population.

Social stress seems to reach deep into cellular control centers to shape key aspects of the immune system—and, as a result, can impair one’s ability to avoid or fight off disease and psychiatric disorders. Now researchers are trying to pin down the molecular mechanisms by which psychological stress is translated into gene-expression changes, and to develop a more precise understanding of the conditions under which stress-mediated gene regulation affects health.
