Selective marker found to indicate aggressive form of breast cancer
Researchers have linked a structural protein called nestin to a particularly deadly form of breast cancer, identifying a new biomarker that could lead to earlier detection and better treatment.
Dual gene therapy suppresses lung cancer in preclinical test
Combination gene therapy delivered in lipid-based nanoparticles drastically reduces the number and size of human non-small cell lung cancer tumors in mice, researchers at The University of Texas M. D. Anderson Cancer Center and the University of Texas Southwestern Medical Center report in the Jan. 15 edition of Cancer Research. more
Combination therapy reduces exacerbations in severe COPD
For patients with severe chronic obstructive pulmonary disease (COPD), combining a long-acting bronchodilator with an inhaled corticosteroid reduced the number of exacerbations by 35 percent. more
Low-dose aspirin offers lower chance of asthma
In a large, randomized, placebo-controlled study of 22,071 healthy male physicians, taking a low-dose of aspirin every other day lowered the risk of receiving an initial asthma diagnosis by 22 percent. more
Relationship between delirium and dementia
Dementia, including Alzheimer's disease, is one of the most devastating conditions of older age. Currently affecting nearly 7 million individuals in the U.S. and 24 million worldwide, dementia leads to total loss of memory and the ability to function independently – making it one of people's greatest fears of aging.
Scientists find new genetic clue to cause of Alzheimer's disease
Variations in a gene known as SORL1 may be a factor in the development of late onset Alzheimer's disease, an international team of researchers has discovered. The genetic clue, which could lead to a better understanding of one cause of Alzheimer's, is reported in Nature Genetics online, Jan. 14, 2007, and was supported in part by the National Institutes of Health (NIH). more
Uncovering a new reason why patients respond differently to the same drug dose
Why does the standard dose of certain medications prove dangerously high for some patients and too low to produce beneficial effects in others? Scientists have added a previously unrecognized factor to the list of explanations (such as age, gender, diet and genetics) for this common problem of individual variability in response to drugs. more
