How brain pacemakers erase diseased messages

...rk by drowning out the electrical signals of their diseased brains. Despite the clinical success of the devices, which have been approved by the Food and Drug Administration and can be found in the heads of about 30,000 Americans, the mechanisms by which deep brain stimulation alleviates disease symptoms are...

Percutaneous aortic valve replacement safe, successful in high-risk patients

... its core. As it expands, the CoreValve covers the diseased natural valve leaflets. During the procedure, the patients were placed on a bypass pump for an average of 30?0 minutes to minimize blood flow through the aorta and ease placement of the replacement valve. All 17 patients survived the procedur...

Veterinary scientists explore poultry virus as cancer killer

...said. NDV utilizes the defects to replicate in the diseased cells. The replication of NDV leads to the death of the cancer cell by a process called apoptosis - also known as programmed cell death or cell suicide- in the cell. ...

Stem cells act through multiple mechanisms to benefit mice with neurodegenerative disease

...may integrate electrically and functionally into a diseased brain. The transplanted cells also boosted the brain's supply of the enzyme Hex, which reduced the lipid accumulations in the treated animals. The experimental treatment also dampened the inflammation that typically occurs in the brains of most degen...

New protein inhibitor impedes growth of cancerous cells

...ision in cancer cells, even though these cells are diseased and have lost some of the restraints on division that normal cells impose on themselves. Because central aspects of cell division are under the control of just a few key kinases, these proteins represent potentially important targets for new cancer t...

Scientists discover new, readily available source of stem cells

...ain disease. The cells grew and "re-populated" the diseased areas. In addition, bone cells produced from the stem cells were successfully used to grow bony tissue in mice, and liver cells were able to secrete urea, which the liver produces from ammonia. The potential to generate a broad range of mature cel...

Scientists clone mice from adult skin stem cells

...hy cells and tissues that could replace damaged or diseased organs. "Scientists are well-aware that tissue derived from someone else's embryonic stem cells would be recognized as foreign and rejected by the patient," says senior co-author Elaine Fuchs, the Rebecca Lancefield Professor at Rockefeller and a How...

UW launches study testing adult stem cells for heart damage repair

... CMI develops when the coronary arteries become so diseased that they limit the flow of blood to the heart and send small blood clots downstream, blocking the small blood vessels in the heart. These blockages can result in a series of mini-heart attacks that, while they may be too small to notice at the ti...

Are scientists making progress in being able to regenerate bone tissue?

...ogress there has been in restoring the function of diseased or damaged bone by bone tissue regeneration. Until recently, say the authors, the use of bone grafts from a different part of the patient’s own body has been the number one choice for attempting to restore function. But there are major problems wit...

Inhibiting blood to save the brain

...r microglia activation and damage to myelin in the diseased mice, allowing them to survive with improved motor function. "Importantly, this approach blocks fibrin's interaction with microglia, but not with platelets, so clotting wouldn't be impacted," said Akassoglou, adding that this potential MS therapy ...

Scientists produce neurons from human skin

... We could then transplant these nerve cells in the diseased areas of the brain," explains Berthod. "This type of procedure seems particularly interesting for diseases such as Parkinson’s, but it’s all theoretical for now. Before we can think of doing such things, we’ll have to improve nerve cell differentiati...

Engineering the heart piece by piece

Among the hurdles: determining which types of cells hold the most potential, and finding the best way to grow those cells to form viable cardiac tissue that is strong, long-lasting and structured at a cellular...

Stem cell therapy shows promise in regenerating damaged muscle in heart attack patients

...nsplanted, the cells promote healing of damaged or diseased tissues. "Because of the participation by top tier sites such as Rush University Medical Center, we were able to conduct a study that was exceptionally well planned and executed" said C. Randal Mills Ph.D., President and CEO of Osiris Therapeutics...

Cancer scientists create 'human' leukemia process to map how disease begins, progresses

...an leukemia research involves studying a patient's diseased cells or a cell line grown from those cells. However, since cancer takes many months or years to develop, just studying the cells at the end of the process does not let you know what the series of changes were that caused the cells to become leukemic...
