Marine sponge leads researchers to immune system regulator

...ease. NKT cells play an important, although still poorly understood, role in regulating all sorts of immune responses. Defects in the system may allow the body to attack itself, leading to chronic inflammation or tissue damage. "It has been extremely difficult to explore the mechanisms that govern the rec...

Ventricular assist devices can be used as bridge to heart recovery without need for heart transplant

...fit from VAD as a bridge to heart recovery remains poorly defined. In a study presented today at the American Heart Association's Scientific Sessions 2004 in New Orleans, Marc A.

African-American heart attack patients fare worse long term

...ans," Mehta said. "These differences, coupled with poorly understood genetic, biologic and other socio-economic factors appear to result in higher mortality rates for African-Americans. "This data also shows that just treating the heart attack acutely may not be enough," he continued. "We also need to focus...

Lung cancer specialist calls for cash to beat 'Cinderella' disease

A small percentage of patients with pancreatic cancer have first-degree relatives with pancreatic cancer. Smoking has been identified as...

Genetic testing can identify ischemic and nonischemic heart failure

Longterm immune memory cells cells do not develop during chronic viral infections

...ey found that chronic memory CD8 T cells responded poorly to both IL-7 and IL-15, whereas acute memory CD8T cells proliferated in response to both cytokines. Additional research could show whether the defect in chronic memory cell response to IL-7 and IL-15 can be overcome by increasing the expression of t...

The researchers, led by Hirohito Kita, M.D., of the Mayo Clinic in Rochester, MN, compared blood samples taken from 18 people diagnosed with chronic sinusitis with blood samples from 15 healthy volunteers. Nasal secretions from ...

Increase in childhood leukaemia may be part due to increased light at night

... Although the causes of leukaemia in children are poorly understood, environmental factors are thought to play a major role in the rising incidence since changes in our genetic make up simply do not happen on this kind of timescale. If this is the case, then it may be possible to take preventative measures...
