Regenerative techniques and devices that aid in reversing human disease and the aging process.
Traditional medicine has been the realm of doctors, and only people who had the intellect and persistence to complete university are able to practice it in developed countries. Separately IT or Information Technology has been developing along, doubling in power roughly every year. Suddenly we are seeing patients 'Google' their symptoms and present their findings to doctors for confirmation. Likewise doctors 'Google' rarer symptoms, the latest treatments and drug interactions in an effort to stay current. They then pass the information back to patients with a prescription to match.
Diagnostics are ever more computer based, and doctors themselves are relying on the results of tried and tested Apps. Take for instance the CANTABmobile app available on iPAd which diagnoses early onset of alzheimers and is smart enough to filter out normal age related memory loss.Add a comment
A pain-free way that reverses the damage of acid attack and re-builds teeth as new has been developed at the University of Leeds. This new treatment will do away with the need for filling teeth completely. It involves painting a peptide-based fluid onto the tooth's surface. The peptide technology is based on knowledge of how the tooth forms in the first place and stimulates regeneration of the tooth defect.Add a comment
A new light adjustable lens implant is allowing any residual errors in vision to be corrected using ultraviolet light without any additional surgical procedures. This lens adjustment is completely non invasive and so predictable that it is possible to give patients 20/20 normal vision without glasses and the ability to see brighter colors.
After age 40 nearly everyone develops some form of presbyopia or cataracts which results in poor focus and loss of color. The only treatment for cataracts is surgery where the old lens is removed and replaced with an artificial one. Previously over 70% of people who have lens implants after cataract surgery or clear lens extraction are left with some longsighted, shortsightedness or astigmatism. This meant that they still needed to wear glasses to achieve good vision. These new adjustable lenses mean that patients get perfectly fitted with a new lens for life.Add a comment
Researchers at The Saban Research Institute of Children's Hospital in Los Angeles have engineered a small intestine in mice that replicates the intestinal structures of natural intestine. Dr. Grikscheit who led the study is concerned with finding solutions for newborns who are born prematurely. These infants are at increased risk for a gastrointestinal disease called necrotizing enterocolitis (NEC), which occurs when the intestine is injured and often removal of the organ is the only option.
Working in the laboratory, the research team took samples of intestinal tissue from mice. This tissue was comprised of the layers of the various cells that make up the intestine — including muscle cells and the cells that line the inside, known as epithelial cells. The investigators then transplanted that mixture of cells within the abdomen on biodegradable polymers or "scaffolding."Add a comment
Aubrey de Grey, a pioneer of anti aging research has predicted a 50/50 chance of bringing aging under medical control within the next 25 years or so. And by then the first person to live for 1,000 years could already have been born. He also predicts the first person who will live to see their 150th birthday has already been born.
Currently we are seeing a an average of three months being added to life expectancy every year and its estimated there could be a million centenarians across the world by 2030. In 2010 there were just 44,000 centenarians. As medical technology advances this trend is only likely to accelerate and get to a point where the average increase to life expentacy per year becomes more than one year.
De Grey believes people will soon visit their doctors only for regular "maintenance," which will include gene therapies, stem cell therapies, immune stimulation and some other advanced medical techniques to help them keep in good shape. "And what I mean by decisive is the same sort of medical control that we have over most infectious diseases today." Preventative geriatrics as he calls it, is where you periodically repair molecular and cellular damage before it gets to the level of abundance that is pathogenic.Add a comment
A very quick video that shows a functioning artificial rat lung. The video was posted just a week ago. Scientists from Massachusetts General Hospital and Harvard Medical School in Boston, led by Harald C. Ott, have successfully grown a rat lung in the lab.
One of the top searches on this site is 'how to increase lung capacity' probably by ex smokers researching how to reverse the damage. (Or extreme athletes!!)Add a comment
It's seems just a matter of time before current reconstructive techniques like dental implants are replaced with more natural regenerative procedures. The first ever international conference on Dental and Craniofacial Stem Cells will take place April 2011, at the New York Academy of Sciences in New York CIty. The conference will be an assembly of many of the world’s most prominent scientists in the field of dental and craniofacial stem cells.
Dr. Jeremy Mao of Columbia University is one of the pioneers of regrowing teeth using stem cells. “The teeth and the face harbor stem cells, just like virtually all other regions of the body; however, stem cells from the teeth and the face have special properties that make them unusual, if not unique, in some cases,” said Dr. Mao. “Dentistry is undergoing a transformation from restorative, such as drilling and filling, to regenerative. This conference represents the first dedicated gathering of stake holders from the scientific community, industry, and government officials who fund and regulate regenerative technologies.”Add a comment
For the first time, scientists have created functioning human intestinal tissue in the lab from pluripotent stem cells. The scientists from Cincinnati Children’s Hospital Medical Center in the U.S. say their findings will open the door to unprecedented studies of human intestinal development, function and diseases.
Other research areas opened up include creating intestinal tissue for transplantation and investigating drugs than can be better absorbed by the body, since the intestine absorbs most drugs taken orally.

Solta Medical, maker of the fraxel laser treatment, has announced it has received FDA 510(k) clearance of its Fraxel re:store®Dual for the treatment of actinic keratosis (AKs) which are a common precancerous skin condition caused by sun exposure on the face or other areas of the body.
In a six month clinical study of 21 people, there was an 83.5% average reduction of AK lesions using the Fraxel re:store Dual's 1927 nm wavelength. Treatments were shown to be effective both on and off the face, including the arms, hands and chest area. Each person underwent a series of two to four treatments with the Fraxel re:store Dual that were spaced two to four weeks apart. No adverse reactions occurred for any of the subjects. In addition, the study found improvement in skin texture and pigmentation following a Fraxel treatment.Add a comment
RNL Bio located in Korea has already launched commercial stem cell therapy for pets like dogs and cats with spinal cord injury since 2008. Now they have announced they are beginning trials of the same treatment on humans. On April 30th the Korean FDA approved its human clinical study to treat patients with spinal cord injury using their product ‘RNL-Astrostem’ that is based on fat derived adult stem cells.
In early 2009 the U.S. FDA permitted Geron Corp to conduct a clinical trial using embryonic stem cells to treat patients with spinal cord injuries. However the RNL Bio method may prove less controversial due to using adult stem cells.Add a comment
