...nformation helps us to determine how intensive the rest of the therapy should be. Our goal is the complete eradication of leukemic cells with the least toxicity to the children." The continued improvement in diagnosis and treatment made possible by MRD, pharmacogenomics and new drug therapies has shifted...

Potential heart benefit found in stem cells

...empting to clarify the extent of stress-induced or rest perfusion defect (scar tissue) in patients with ischemic cardiomyopathy, or blockages in the arteries leading to the heart infarction. In the study, 17 patients with ischemic cardiomyopathy were treated with a combined percutaneous injection (both i...

...ells without affecting healthy lymphocytes nor the rest of the normal cells. Made-to-measure treatment With the molecular action mechanism understood, researchers investigated why retinamide did not affect healthy cells and they discovered other factors to explain the phenomena. So, apart from molecul...

Are dancers genetically different than the rest of us? Yes, says Hebrew University researcher

What makes dancers different than the rest of us? Genetic variants, says a researcher at the Hebrew University of Jerusalem. In a study published in the American journal, Public Library of Science Genetics, Psychology Prof. Richard P. Ebstein and his research associates have shown, throug...

How to grow a bigger brain

Secrets of the sea yield stronger artificial bone

...one. We provide the body with scaffolding, and the rest of the work is done by cells." The Berkeley Lab scientists also hope to create samples that are large enough to work with artificial joints. Their ice-templated fabrication technique also holds promise for many applications in addition to artificial...

Radiotherapy advance points way to noninvasive brain cancer treatment

... in the U.S., half will die within a year, and the rest within 3 years. Currently, the only treatments that stretch survival limits are exceptionally invasive surgeries to remove the tumor and radiation treatment with the maximum tolerated dose - all of which leads to a painfully low quality of life. Beca...

Weighting cancer drugs to make them hit tumors harder

... going to the tumor while reducing toxicity to the rest of the body," said Fan Yuan, Ph.D., co-author on the paper and an associate professor of biomedical engineering at Duke. "We can adjust the weight higher or lower depending upon where we want the drug to concentrate." Even drugs with vastly elevated...

Life, the remake

...y of Sciences. "Evolution at this level, like the rest of history, is predictable, perhaps more predictable than people want to imagine," Vermeij said. "Many traits are so advantageous under so many circumstances that you are likely to see the same things again and again." Vermeij's view contrasts with ...

UC San Diego biologists solve plant growth hormone enigma

...e plant led to defects in those tissues, while the rest of the plant appeared normal. "Knowing which auxin genes are activated when should make it possible to modify plant development," said Zhao. "It wouldn't require adding any new genes to the plant, just changing when the appropriate auxin genes were...

New device could cut chemotherapy deaths

...into the cancer site, and a much lower dose to the rest of the body. This is a more localised way of killing cancer cells than the current method of injecting the chemical into a cancer sufferer's vein so that it is carried around the body. As well as reducing the side-effects, the new drug delivery veh...

Cincinnati surgeons report new treatment for often-fatal injury

...he damaged area without stopping blood flow to the rest of the body. The endografts are regularly used in vascular surgery to treat aneurysms in the abdomen, Dr. Giglia explains, but they are too short to fully bridge the damaged area in the chest. "Used alone, extender cuffs are hard to align and oft...

Epidemic of unneeded amputations

...in diabetics, plaque blocks arteries, resulting in rest pain, development of foot ulcers and onset of limb loss. The CLiRpath procedure, using a "cool" excimer laser and catheter system developed by Spectranetics Corp. (NASDAQ: SPNC), vaporizes arterial blockages, restores blood flow, and this surgery pro...

...bout that drug," says Zhang, who hopes to test the rest of the chemicals in the collection soon for their ability to interfere with the enzyme tested in this study. Finding a drug that can tame this enzyme could lead to new treatments for heart disease, diabetes, memory disorders and certain cancers, for ...
