Children get lab-grown organs

The urethra is a narrow tube, which provides the bubble with the genitals, a conduit, usher waste out of the body. History of HIGHLIGHTSScientists reported successful reconstruction of Urethras in 5 young patients with own CellsThe challenge with traditional urethra replacement is the creation of a viable tube, which is grafts not CollapseThe engineering ImplantedRegenerative appeared medicine harnesses body which were ability to heal normal about three months after it, ItselfRELATED TOPIC Wake Forest UniversityBiotechnologyHealth and fitness (dpa) - engineering institutions begins with something fehlt-- a phantom organ of the body of a patient gives incredible discomfort, dysfunction, or pain. It ends with a Star Trek-esque feat of engineering through the replacement missing organs culled with cells from a patient's body. In a small pilot study, Monday in the Lancet reconstruction of Urethras in five young patients published reported scientists successfully, with their own cells. "We could create own fabric patients that actually belongs there," said Dr. Anthony Atala, author of the study and Director of the Institute for regenerative medicine at Forest University School of medicine wake lead. "If the tissue is to be available, we will do hopefully better by the patient." Patients had their engineered Urethras implanted from March 2004 to July 2007 the Federico Gomez children's Hospital in Mexico City. Their Urethras to several years follow-up function. The urethra is a narrow tube, which provides the bubble with the genitals, a conduit, usher waste out of the body. If that - sometimes natively or as a result of the disease, pelvic fractures or other trauma-damaged is you usually according to Atala replaced with tissue from the lining of a patient cheeks harvested or grafted skin from another part of the body, use. "Unfortunately for the narrow structures in the body (like Urethras), they are kind of complex, because they tend to reduce," Atala said, adding that conventional urethra replacement more than half beats the time fail. "Each institution has its own challenges." The challenge with traditional urethra replacement creates a viable tube, one that is not easily reduced. And this is where engineering Urethras can provide some benefit. The first step for the construction of a new urethra is a very small piece of the patients of own tissue (about half as large as a stamp) take out of the bubble. Cells are from the biopsiert website, allows multiply, scraped that muscle cells from urethra cells separated. It is in the next steps in the process, which sound like science fiction. If there is a sufficient number of cells, scientists "Seed" seven - so as a new lawn seed würde-- perform on a grid, the core techniques is shaped like a urethra. The inside of the network is coated with urethral cells, whereas outside muscle cells. "It is as cake bake a layer, but it does one level at a time," said Atala. The sown structure is in an incubator for about two weeks, in a "" placed the cooking process, the Atala says how cell growth occurs within the body simulated. Then, the newly developed urethra is ready to be implanted in the patients. "During the operation, we go in the area that was damaged, clean, scar tissue and plug - in a new, engineered urethra," said Atala. "It sounds simple, but it is a fairly complex surgical procedures." "This is a narrow structure and it must fit just right." According to the study which was carried out engineering grafts normal implanted approximately three months after they were. Patients of Urethras retained worked normally within a few weeks after the operation and the function for up to six years. "This is an exciting study that shows that a viable option for complex urethral tissue engineering can be repairs," said David A. Vorp, Professor of Bioengineering and heart thoracic surgery at the University of Pittsburgh, who was not involved in this study. "It shows that the patient's own cells can be used, is the possibility of rejection to eliminate." VORP added that biopsies will carry their own risks such as infection and other complications, and the study in a larger study group needs to be replicated. Although the current study had registered only a few patients, Vorp said it is "an important step in the direction of important new means for urethral repair." Atala admits that there are some years before engineering institutions becomes the norm, and that it is not yet clear whether this same technology in adults will work. He said that in addition to the patients with urethra dysfunction, patients with other complex small vessels, the Probleme--could such as blood vessels, which one day will benefit from this technology after heart bypass surgery to reduzieren--. "There is a huge population with small vessel disease where the ships reduce and close to keep," said Atala. "The most important concept here is a narrow tubularized, complex structure that doesn't collapse in the long term." Atala and colleagues reported similar success in seven spina bifida patients to replace its dysfunctional bubbles in 2006. Scientists at Wake Forest have successfully developed more than 30 tissues and organs, including miniature liver, heart-valve-pressure even institutions such as human skin and kidney-in the laboratory. Scientists such as Atala regenerative medicine say a new frontier where medicine is the doctors cure, rather than merely treatment of diseases with the body's natural ability to heal itself could see. Autologous cell - or cells that taxes of a patient's body - can be transplanted organs without rejection. Still, all this is many years away. Most of these emerging technologies are not yet ready for widespread implantation, and the cost of the regenerative medicine at this early stage is often much higher than the conventional methods. "An interesting challenge with many of these technologies and regenerative medicine, you must, go slowly", Atala said. "The key is too slow going and have long-term follow up." "Keep patient safety first."

Complex migraines: this is you?

23 Million Americans suffer from some form of unusual migraines a ne, the complex could be described. History of HIGHLIGHTSNational Headache Foundation says that 23 million Americans suffer unusual migraine expert says that complex migraines are neurological event of the HeadacheComplicated survived the migraine with a number of other serious ConditionsRELATED TOPICSMigrainesBrain and nerves, health (CNN)-Barbara A. Mosgrave of Annandale go hand in hand können(Virginia), remember not the first time, it happened. It is still a blur. But she thinks that the episodes began 50 years ago. At least that's when she told someone her, she spoke gibberish in mind. "My friends would look at me and say 'What you're talking about?'" At 71 know to expect Mosgrave to the unexpected. As she was a teenager, that the you has suffered from severe migraines. "The kind that cause you to go in a dark room, and the door to close;"the pain is bad, she said. But she knew they control how and why they happened. Still, when it came to her speech, the different was. "I had no idea that I was babbling," she says. But when told sometimes, that it has no sense began her, she began to questions why their words and phrases from all were wrong? At the beginning of all Mosgrave thought they might be with mini strokes but if she attended many neurologists the same told her: it was a form of headache classified as suffering from a complex migraines. Do you live with complex migraines? Share their Council "which is different from the common migraine complex migraine is that this neurological event survived the headache itself," says Dr. Marc Schlosberg, neurologist in Washington Hospital Center in Washington, D.C., and Mosgrave the doctor.

How the human penis lost his spikes

Scientists are trying that are the reasons, why humans and chimpanzees have key differences. History of HIGHLIGHTSHumans a change in the genome is missing that penis spine, sensory WhiskersSome, scientists suspect "turn on", that the absence of spines encouraged BondingChimpanzees pair and both mice penis spikes and sensory whiskers (CNN) – have you read the headline, and it probably giggling. Go ahead. Refer to your system. Then inhale deeply and consider how evolution a few specific parts of the body concerned, and why. Some are humans and chimpanzees parts more than 97% of the DNA, but it fairly obvious differences in appearance, behavior and intellect. Scientists are now more than ever, learn what makes us uniquely human. We know that people have bigger brains and within the brain, a larger angular gyrus, a region associated with abstract concepts. Also male chimpanzees have smaller penises than people, and their penises have thorns. Not like Porcupine needles or something, but small top projections on the surface, basically the organ make the bumpy. A biologist at Stanford University wanted to continue to investigate why humans and chimpanzees have such differences Bejerano Gill, school of medicine and colleagues. Analyzes the genomes of humans and closely with primates and more than 500 regulatory regions-sequences in the genome responsible for the control of generations, the chimpanzees and other mammals, but not discovered people. In other words, they make a list of the DNA which has disappeared from the human genome during millions of years of evolution. Results from their study will be published in the journal nature. Think of it as light bulbs and their switches, where the light bulbs are gene and the switch are these controlling DNA sequences. If it can not onion, the switch does not turn on the light. Now think of, it is a PEAR and enable five switches at different times in different places. If the switch way take one, works the bulb in the four other contexts, but not in the fifth. This study deals with two specific switches. Bejerano and colleagues took the switch information from a chimpanzee genome and in the main "connected to" to a reporter gene, a gene, whose Auswirkungen scientists can track how an organism develops. You injected egg to see the reporter gene in a mouse, what would do the switch.

7 Tons of beef recalled on E. coli fears
