A new study has shown that taking ibuprofen on a regular basis can lower your risk of developing Parkinson’s disease. Jason Ramsey from TopNews reports, “The research involved 136,474 people who did not have Parkinson’s disease at the beginning of the research. They were questioned about their use of non-steroid anti-inflammatory drugs (NSAIDs), including aspirin, ibuprofen and acetaminophen.” The study revealed that those who took ibuprofen on a regular basis were 40% less likely to develop the disease than people who didn’t take the drug. Also, those who took larger doses of the drug had an even lower risk than those taking smaller levels of the drug.A new study has shown that taking ibuprofen on a regular basis can lower your risk of... more

If you needed stem cells implanted in your brain to treat a disorder, you might be able to just snort them instead. New details from a University of Minnesota researcher's initial tests show the stem cells actually make it to the brain when snorted rather than implanted through surgery. Talk about a medical improvement.
The research, conducted by Willaim Frey of the University and his colleagues in Germany, shows promise for other drugs that don't usually penetrate the blood-brain barrier, according to the U.S. News and World Report story. If the cells are suspended in fluid, they quickly reach the brain fully intact. The research was recently published in the European Journal of Cell Biology.
How did they conduct the research? Having mice sniff dropped of adult rat stem cells. Sounds like a task in itself. More from U.S. News and World Report:
An hour later, rat stem cells were clearly visible in the mice's brains. To make sure the ability to penetrate the brain wasn't limited just to those cells, they also had rats snort a second type of cells, from human brain tumors. These cells also penetrated the brain within an hour.
They likely traveled to the brain along the olfactory (smell) nerves through small holes in the cribriform plate, a thin horizontal part of the skull at the base of the brain. They also likely traveled inside fluid-filled spaces that surround blood vessels passing from the nose to the brain.
Just above the cribriform plate, olfactory nerves connect to the olfactory bulbs, two round extensions of the brain that process smell. Stem cells were found in the olfactory bulbs and also in the cerebral cortex, cerebellum, and other brain regions.
Stem cell treatments for brain disorders aren't approved yet by the Food and Drug Administration, but researchers hope this easy-to-administer method could help advance research into possible treatments for head injuries, stroke, Parkinson's disease, Alzheimer's disease, and Huntington's disease.If you needed stem cells implanted in your brain to treat a disorder, you might be... more

When Chris Stewart crashed his racing car, the force of the smash was so great that his head was wrenched from the top of his neck.
In fact Chris is only one of six people to survive his 'hangman's injury' - and the first to fully recover thanks to a risky seven-hour operation.
Surgeon Evan Davies said the youngster was one of the few to survive the devastating injury, also known as 'internal decapitation'.

"Recent breakthroughs in bionics and lab-grown body parts — along with news last month that a Swiss research team aims to recreate the intricacies of the human brain within a decade — show science is rapidly creating many of the parts needed to build a fully functional human almost from scratch.
While the ultimate goal remains years if not decades away, and some aspects may be ethically questionable, the work is already helping people live more bearable and productive lives."
***
The article continues by going through body parts and describing how close we are to being able to create them; for example "the first prototype of an artificial liver was grown in a lab in 2005. UCLA researchers are working on a wearable artificial kidney. Scientists at the Juvenile Diabetes Research Foundation expect to have a portable pancreas on the market in a few years" and "It is not impossible to build a human brain and we can do it in 10 years," Henry Markram, who leads the Blue Brain project, told the BBC."

The odds of Human Genome's drug succeeding were, according to most analysts, low. Results from an earlier trial had been disappointing and other drugs, including Biogen Idec Inc (BIIB.O) and Roche Holding AG's (ROG.VX) Rituxan, and La Jolla Pharmaceutical Co's (LJPC.O) Riquent -- both failed in late-stage lupus trials.
Yet, results of Human Genome's 52-week trial -- the first of two requested by U.S. regulators -- showed 57.6 percent of patients taking a high dose of Benlysta experienced an improvement in their symptoms, compared with 43.6 percent who took a placebo.
"Benlysta could be the first true disease-modifying therapy for lupus patients -- a blockbuster opportunity," said Joseph Schwartz, an analyst at Leerink Swann.
Of patients who took a low dose of the drug, which is administered once a month by IV infusion, 51.7 percent showed improvement in their symptoms, a figure that was also statistically significant. [ID:N201399]
Benlysta's success moved the shares of other companies trying to develop lupus drugs, such as Immunomedics Inc (IMMU.O) and ZymoGenetics Inc (ZGEN.O).
Shares of Immunomedics rose 12.5 percent to $3.43, while shares of ZymoGenetics, which is developing a drug in combination with Merck Serono, a unit of Germany's Merck KGaA (MRCG.DE), rose more than 13 percent to $4.94.
Lupus is a complex disease that causes the immune system to attack the body's own tissue and organs, including the joints, kidneys, heart, lungs, brain, blood or skin. Symptoms include achy joints, fever, arthritis, kidney damage, chest pain and skin rash.
Data from the 867-person trial, known as BLISS-52, take the company one step closer to being the first to have a new lupus drug approved in 50 years. Multiple drugs are approved for other indications and used to treat lupus, but none has been approved specifically for the disease in decades.

A Chinese hospital in southwestern Sichuan Province will import four genetically-engineered pigs from Harvard University to carry out pig-to-monkey organ transplant experiments, a doctor said Friday.
Xenotransplantation is a surgical procedure in which tissue or whole organs are transferred from one species to another. Harvard University was one of the earliest institutions in the world to conduct such studies.
In addition to organ transplants, medical and science workers at the lab plan to use the four pigs to do other research, including how to apply pig's tissues, such as skin, bone and vein, to cosmetic surgeries and treatment of injuries.A Chinese hospital in southwestern Sichuan Province will import four... more

One of the best articles I've read in a very long time. Scientists are finally "cracking the code" to our existence via the study how cells and electrons act in time. Some travel back in time to work. We may be on the cusp of discovering the Ancient answer to what we are on a quantum level.
Very well written article.
Here's an excerpt:
Not only does quantum phenomena occur in living systems, but the basic processes of life we take for granted rely on the transfer of information backward in time. Life is so magical because it cheats.
Although the mechanisms by which a living cell can prevent decoherence by dampening its own chemical “noise” remain utterly mysterious, findings such as Engels' conclusively demonstrate that room-temperature quantum computing is possible (and knowing how something works isn’t always necessary in order to use it). And Engel’s group isn’t the only team to detect it: other laboratories have implicated a phenomenon called electron tunneling (micro-teleportation, in which an electron disappears in one location and instantaneously appears somewhere else without having traveled the intermediate distance) at work behind a range of organic phenomena, from our sense of smell and the activities of our enzymes to the neutralization of free radicals with anti-oxidants… possibly even consciousness itself. Paul Davies (Arizona State University) and JohnJoe McFadden (The University of Surrey) have independently suggested that computation in the netherworld of quantum coherence might explain how the earliest self-replicating molecules overcame the inestimable odds against them –- life’s very existence may be the consequence and continued operation of a quantum computer. We may ultimately have to accept our human quest for qubit calculation as a kind of biomimicry, rather than something new and unique.One of the best articles I've read in a very long time.
