Researchers examine long-term risks of exposure to medical radiation

Article Abstract:

The frequent use of radiation as therapy and in diagnostic procedures, such as computed tomography (CT) scans, has caused concerns about the increased risks of developing cancer. Epidemiologists are studying people who have been exposed to medical radiation, noting which individuals may be especially sensitive and whether interactions with other therapies, medical conditions and lifestyle factors may be of influence, to learn more about long-term effects of radiation used in health care settings.

Researchers find genetic clues to chronic fatigue syndrome

Article Abstract:

Research by a multidisciplinary team of researchers links chronic fatigue syndrome with genes that have roles in the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system, specifically, genes involved in the body's response to stress. The investigators found that the three genes containing the most relevant and frequent of these polymorphisms are associated with brain function, stress reactions, and emotional responses.

Researchers use dots to light up tumor cells

Article Abstract:

Researchers are expected to see the minute-by-minute activities of cancer cell, with a new technology that uses fluorescent inorganic nanocrystals that glow under UV light. The study included quantum dots in conjunction with mutiphoton and emission scanning microscopy in which each dot emits a different color from blue to infrared, which helps the researcher to identify each of five populations of tumor cells.
