Panel offers expert analysis on causes, prevention of stent thrombosis
... When stent struts separate, they leave a gap that exposes the artery and becomes the focal point for the build-up of scar tissue or even a blood clot. The risk of stent fracture is greatest at the point where stents overlap or where there is repeated bending of the stent with each cardiac contraction. "As...American Journal of Lifestyle Medicine from SAGE explores how lifestyle affects heart disease
... Angelopoulos, PhD, MPH, and Linda Zukley, MA, RN, exposes the truth about coronary heart disease (CHD) and its causes. "In many ways," write the authors, "coronary heart disease represents the quintessential lifestyle disease of developed countries. Six of the major risk factors for developing CHD involve...Fast test for low blood flow in dogs detects early heart trouble
...t, George says, is that CT imaging, like PET, also exposes patients to radiation from X-rays, but PET takes nearly one hour to perform, whereas CT scanning is quicker. To assess if blood flow in dogs could be accurately measured with 64-CT, researchers compared the new scanner with an existing test that i...Newest in CT imaging technology -- dual energy source -- now being utilized on patients at Penn
...r or claustrophobic patients. Plus, the new system exposes patients to as much as 50% less radiation dose because it obtains images in half the time," adds Litt.

... outcome," says Dr. Van geertruyden. This finding exposes a danger that implementing new malaria combination therapies to treat the disease in immune-suppressed patients could lead to the emergence and spread of antimalarial drug resistance.

The tank then moves along a track that exposes the medical device to nine different EAS systems and five tag deactivators that use various types of magnetic, acoustic-magnetic and radio frequency technologies.

...unts of radioactive iodines in their glands. This exposes the thyroid tissues to the radiation which in turn, increases the chance of getting thyroid cancer and other diseases of the thyroid gland later in life." The researchers estimate that 75% of the thyroid cancer cases would have been avoided in the ...Novel virus entry mechanism could lead to new drugs against poxviruses
...ting the outer membrane with polyanionic compounds exposes the virus, allowing antiviral antibodies to be more effective. The disruption of the outer membrane also limits the spread of the virus in the body. Professor Geoffrey L.
