Autoinflammatory Disease Model Reveals Role For Innate, Not Adaptive, Immunity PDF Print E-mail
Thursday, 11 June 2009 15:51
Researchers at the University of California, San Diego School of Medicine have developed the first mouse model for auto-inflammatory diseases, disorders that involve the over-activation of the body's innate, primitive immune system. Their study, published early online in Cell Immunity on June 4, suggests that the innate – not adaptive – immune system drives auto-inflammatory diseases. The findings could open new therapeutic directions for research into disorders such as gout or inflammatory bowel disease.

New Pathway Found Underlying Pulmonary Hypertension PDF Print E-mail
Monday, 08 June 2009 12:00
Pulmonary hypertension is an unremitting disease caused by a progressive increase in blood pressure in the blood vessels of the lung; it leads to heart failure and ultimately death. Currently there are limited treatment options. However, You-Yang Zhao and colleagues, at the University of Illinois College of Medicine, Chicago, have identified in mice a new molecular pathway underlying pulmonary hypertension that they hope might provide novel therapeutic targets.
Dentures: 3D Digital Images Of Tooth Contours May Replace Plaster Models PDF Print E-mail
Friday, 05 June 2009 16:54
Using current technology, dental technicians can only make dentures using a bite impression. The silicone template for this plaster model is made by the dentist, in a procedure which is unpleasant for the patient. In future a 3-D digitizer will provide the teeth contours – without a plaster model.

Benefit Of Aspirin For Healthy People Is Uncertain PDF Print E-mail
Wednesday, 03 June 2009 17:05
A new study has shown that, while taking aspirin is beneficial in preventing heart attacks and strokes among people with established cardiovascular disease (secondary prevention), its benefits don’t clearly outweigh the risks in healthy people (primary prevention).
Good News For Some Hard-to-treat Hepatitis C Patients PDF Print E-mail
Tuesday, 23 June 2009 16:04
In a multi-center trial led by a Saint Louis University researcher, investigators found that a new combination therapy of daily consensus interferon and ribavirin helps some hepatitis C patients who have not responded to previous treatment. The findings, published in the June issue of Hepatology, offer a new option for hepatitis C patients, and may be effective even for those patients with factors that make their condition difficult to treat.
Cardiac Rehabilitation Saves Lives PDF Print E-mail
Thursday, 18 June 2009 15:31
Coronary heart disease (CHD) is the leading cause of death worldwide and a major driver of medical and economic costs, especially among older adults. It has long been established that cardiac rehabilitation improves survival, at least in middle-aged, low- and moderate-risk white men. Now a large Brandeis University-led study published in the Journal of the American College of Cardiology reports that older cardiac patients benefit as much from cardiac rehab as their younger counterparts.
Breakthrough In Understanding Severe Asthma Has Potential For New Treatment PDF Print E-mail

Death Rates Same For Diabetes And Heart Disease Patients Receiving Drug Therapy Or Surgery PDF Print E-mail
Monday, 08 June 2009 12:03
There is no difference in mortality among patients with type 2 diabetes and stable heart disease who received prompt bypass surgery or angioplasty compared to drug therapy alone, according to a landmark study focused exclusively on patients with both conditions. The study, which was led by investigators at the University of Pittsburgh Graduate School of Public Health, published in the June 11 issue of the New England Journal of Medicine and presented at the American Diabetes Association 69th Scientific Sessions, also found that while prompt bypass in patients with more severe heart disease did not lower mortality, it lowered their risk of subsequent major cardiac events.

First Multi-pixel Terahertz Modulator Created PDF Print E-mail
Tuesday, 02 June 2009 17:10
Scientists have for the first time devised a multi-pixel modulator for light waves at terahertz (THz, or 1012 Hz) frequencies. The formal study of THz radiation, which can be described as far-infrared light, dates back many years, but has become increasingly widespread since around 1990, when efficient methods for generating and detecting the radiation become available. The expected applications include carrying out biological spectroscopy and imaging buried structures in semiconductors.
