Brain inflammation may be friend, not foe, for Alzheimer's patients

..., not causing the crash. The work suggests that doctors not rush in to turn off molecular events that scientists have widely considered to be detrimental in people with the disease. The findings could also renew efforts to develop a vaccine or other strategies against Alzheimer’s by engaging the body’s im...

Blood test may help signal tumor's remission, return in throat cancer patients

Research shows cord blood comparable to matched bone marrow

... When doing bone marrow or cord blood transplants, doctors generally try to have the donors’ and recipients’ HLA types match as closely as possible. Wagner added that increasing the inventory will increase the chance of finding donors for ethnic and racial minorities currently underrepresented in volunteer...

Blood-brain barrier breached by new therapeutic strategy

...ation or antibodies to the peptide. Currently, doctors use various methods to deliver therapeutic drugs directly into the brain. These methods involve invasive procedures that result in only localized delivery around the site of injection. The new research provides a safe and non-invasive method for deli...

Adult stem cells from human cord umbilical cord blood successfully engineered to make insulin

...adult stem cells rather than embryonic stem cells, doctors practicing so-called regenerative medicine eventually might be able to extract stem cells from an individual’s blood, then grow them in the laboratory to large numbers and tweak them so that they are directed to create a needed organ. In this way, he...

Avian influenza survivors' antibodies effective at neutralising H5N1 strain

...known cases in humans, 185 of them fatal. Now, doctors based at the Hospital for Tropical Diseases in Ho Chi Minh City, Vietnam, the Institute for Research in Biomedicine in Bellinzona, Switzerland and the National Institute of Allergy and Infectious Diseases in Bethesda, US, have shown that monoclonal a...

'Virtual Patient' to simulate real-time organ motions for radiation therapy

...etermine accurate and effective radiation dosages, doctors must consider such issues as the breathing functio...n treatment." Real-time simulations could allow doctors to spot the small fractions of time when the lungs, liver, kidneys, and eventually the heart, are st...

Mice with a migraine show signs of brain damage

...e headaches and by using medications prescribed by doctors to prevent them. “Normally, the focus of migraine treatment is to reduce the pain. We’re saying that migraines may be causing brain damage, and that the focus should be on prevention, which will stop not only the pain but also minimize potential d...

Novel system developed to turn data into real-time, interactive 3-D images

...gy developed at Kent State University will provide doctors with a dramatically improved ability to evaluate medical images that are commonly used. This patent-pending technology allows for interactive viewing of large image data sets from virtually any medical imaging device and has led to a licensing agreem...

Students invent protective pouch to enhance cell therapy

...niors and two freshmen, working with Johns Hopkins doctors and engineers, devised a protective "pouch" that should fit inside the portal vein, which feeds into the liver. This pouch would keep microcapsules of therapeutic cells in one place, allowing them to thrive and send out needed insulin. The inventors ...

Study offers clues to 'Broken Heart Syndrome'

...s of "broken heart syndrome" remain a mystery, but doctors will soon have an easier time recognizing and treating this rare, life-threatening condition, thanks to data being reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI), May 9?2, 2007, ...

Bones in motion: Brown scientists to create new 3-D X-ray system

...earchers are creating a technology that will allow doctors and scientists to do the seemingly impossible: See inside living humans and animals and watch their bones move in 3-D as they run, fly, jump, swim and slither. This high-resolution, high-speed imaging system will contribute to better treatments fo...

Transfusion expert urges wider use of filtered blood

...ioners are not convinced they hold many risks. But doctors at the University of Rochester, leaders for two decades in the study of "transfusion immunomodulation," believe otherwise. Giving donor blood to someone, Blumberg said, is akin to a temporary organ transplant. In many cases the transfused blood modif...

Scientists genetically engineer tomatoes with enhanced folate content

...he folate is already present in the food." Will doctors be recommending a healthy dose of salsa for would-be pregnant women anytime soon? Probably not, the researchers say. "It can take years to get a genetically-engineered food plant approved by the FDA," Hanson said. "But before that is even a questi...

A 'traffic light' for neurons means 'go' for improving brain research

...ignals, such as movement instructions, could allow doctors to bridge blockages in damaged spinal columns, perhaps restoring some function to the limbs of paralyzed patients. Finally, the technique could be useful in teasing out the largely unknown functioning of healthy brains. "One day we'd like to be...

Woven scaffolds could improve cartilage repair

...e said. "The use of this scaffold will also permit doctors to treat larger areas of cartilage damage, since the current approaches are only suitable for repairing smaller areas of cartilage damage or injury." Cartilage is a type of connective tissue that lines the ends of bones, providing cushioning and a...

NT researchers discover breakthrough in malaria treatment

...he risk of malaria is greatest. "Scientists and doctors wage a constant battle to develop and implement effective treatments for malaria. This study is one of the first to highlight the best treatment of drug resistant strains of vivax malaria found in the Asia pacific region." said Dr Price. "It als...

Radiation therapy combo cures prostate cancer long-term

... for prostate cancer. Over the course of 15 years, doctors followed 232 men with early-stage prostate cancer who received a course of external beam radiation therapy followed by permanent seed implants a few weeks later. Sixty-five percent of these patients had T2b-T3 disease and the entire group had an aver...
