One example is nonlinear predictive control. This makes it possible to predict future behaviour following interventions...

First animal model for pancreatic cancer may lead to early detection of disease

...derstanding the pathology of how pancreatic cancer develops is essentialto finding a way to prevent or treat this disease. Drs. Sunil R. Hingoraniand David A.

... may occur in younger subjects. Polycythemia vera develops slowly, and most patients do not experience any problems related to the disease after being diagnosed. However, the abnormal bone marrow cells may begin to grow uncontrollably in some patients leading to blood hyperviscosity. Patients with polycy...

...ch get rougher as they get thicker. The paper also develops a theoretical model that shows that the material's extreme smoothness arises from the process of growing the films, in which heat from ions deposited on the surface dissipates, melting and flattening the surface.

Research on spleen cells could yield potential cure for Type 1 diabetes

...w approach to diabetes treatment." Type 1 diabetes develops when the body's immune cells mistakenly attack the insulin-producing islet cells of the pancreas. As islet cells die, insulin production ceases, and blood sugar levels rise, damaging organs throughout the body. In their earlier study, Faustman's te...

Dying nerves cause even more harm after spinal cord injury

.... Interestingly, this latent, or secondary, injury develops over days and even weeks after the initial injury. It also appears to cause larger, more debilitating lesions in the spinal cord, said Randy Christensen, the study's lead author and a postdoctoral researcher in neuroscience at Ohio State University. ...

Ten-year study leads researchers to psoriasis genes

...e. "Since only 2 percent of the general population develops psoriasis, there are clearly many other genes involved in determining psoriasis risk, and the genes we identified are low-risk," Bowcock says. "But it's encouraging because they're not genes we would have predicted to be involved in psoriasis, and no...

Diet may improve cognition, slow aging, and help protect against cosmic radiation

Studies suggest that antioxidants may also protect against certain cancers, heart disease and other non-neurological age-related diseases.

The outer layer of proteins is often arranged in an intricate pattern of interlocked molecules that can give the part...

Hospitalization injuries prove costly to patients, health care system

"If you don't have that, you are a rock, you sit there and take whatever comes along," Capecchi says. "So we are concerned with how the brain is put together and maintain...

No current treatments are consistently effective. Scientists had believed that the cause of the disease would be revealed...

Sick Kids researchers link maternal folic acid intake to decrease in deadly childhood cancer

...000 children in North America. Because this cancer develops in utero, neuroblastoma is the most commonly diagnosed malignant tumour of infancy. The aggressive nature of this tumour also makes it the most common cause of cancer-related death among children one to four years old. When a number of Sick Kids onco...

New gene for rare inherited paralysis may aid other spinal cord research, too

...ding a mutation responsible for a form of HSP that develops in early childhood and may resemble familial cerebral palsy. That discovery, of a gene on chromosome 14 that encodes a protein called atlastin, has already yielded a diagnostic test that can give patients a firm diagnosis to tell them if they have or...
