Exploring the molecular origin of blood clot flexibility

...del that can then be used to predict the effect of changes at one scale on clot properties at other scales. Such a model should be useful for developing prophylactic and therapeutic treatments for many aspects of cardiovascular disease and stroke, suggest the investigators. ...

Genes and biomarkers that allow doctors to choose the right therapy for the right patient

...consistent with clinical experience. For CI-1040, changes in the MEK pathway were most strongly associated with response. Predictors based on combinations of molecular correlates of response were able to quantitatively predict individual cell line responses. "The concordance of our markers of response ...

Carnegie Mellon University research shows how sensory-deprived brain compensates

...n-depth studies of brain plasticity in response to changes in how an animal senses its environment. Ultimately, we want to understand at the molecular level the dynamic between sensory use and neural plasticity," Barth said. ...

Prenatal cocaine's lasting cellular effects

...e altered D1 receptor trafficking may underlie the changes in neuronal architecture and behavior that Stanwood and others have previously observed. What remains to be determined, he cautioned, is whether D1 receptor localization is affected in humans exposed to cocaine prenatally. If found in humans,...

Twin studies reveal genetic components leading to cardiac and kidney disease

... study shows that both elevated blood pressure and changes to the kidney’s filters are caused by genetic variation at multiple points along the adrenergic pathway. Links between adrenergic activity and renal injury could lead to novel approaches to predicting, preventing, diagnosing and treating kidney dise...

"Given the immense changes that took place in South America following the arrival of the Europeans it is surprising that this crop has remained unaltered for hundreds of years."

Scientists find new genetic clue to cause of Alzheimer's disease

...tively short segments of DNA where disease-causing changes could lie. The study did not, however, identify specific genetic changes that result in Alzheimer's. Richard Mayeux, M.D., of Columbia University, Lindsay Farrer, Ph.D., o...

Global 'sunscreen' has likely thinned, report NASA scientists

...ll of aerosols is due to human activity or natural changes will have to await the planned launch of NASA's Glory Mission in 2008.

Growth hormone is not the anti-aging bullet for healthy adults

...at the synthetic hormone was associated with small changes in body composition but not in body weight or other clinically important outcomes. Further, people who took GH had increased rates of unhealthy side effects such as soft tissue swelling, joint pain, carpal tunnel syndrome, and, in men, abnormal bre...

Cheaper, better disease treatments expected from faster approach to developing antibodies

...enes that produce antibodies are introduced. These changes result in slightly altered antibodies that may attach more strongly to a disease protein. The interaction between the antibody and the disease protein blocks the protein from doing harm in the body, effectively short-cutting a disease process. Ge...

Inflammation may play role in metastasis of prostate cancer

...ancer metastisizes or not is determined by genetic changes within the cancer cell itself. But this hypothesis didn't explain why metastases appear many years after the initial tumor. "Our findings suggest that promoting inflammation of the cancerous tissue, for instance, by performing prostate biopsies, ...

QUT scientists on the way to sifting out a cure for HIV

.... "With this in mind we have introduced radical changes to the membrane texture because it is the membrane texture which is crucial to the separation efficiency of the material," he said. "It is scientifically known that a mesh structure is the most efficient form of filtration and we are the first gro...

Notorious cancer gene may work by destroying messenger

...y an unidentified enzyme. Contact with this enzyme changes the properties of PMR1, and this enables it to join with, or bind to, its target mRNA. Peng then used monoclonal antibodies to isolate PMR1 and the enzyme while the two were bound together, capturing both. After separating the two, the investigat...
