OHSU Cancer Institute researchers study breathing during radiation
Oregon Health & Science University researchers have determined exactly how much breathing affects prostate movement during radiation treatment. view more (2008-09-24)
Appropriate timing in the use of breast shields in children can further reduce MDCT radiation dose
Using breast shields during pediatric chest MDCT reduces radiation dose and minimally increases image noise, according to a recent study conducted by researchers at Duke University Medical Center in Durham, NC and the University of Arkansas for Medical Sciences and Arkansas Children's Hospital in Little Rock. view more (2008-02-13)
New oral agents may prevent injury after radiation exposure
Researchers from Boston University School of Medicine (BUSM) and collaborators have discovered and analyzed several new compounds, collectively called the ''EUK-400 series,'' which could someday be used to prevent radiation-induced injuries to kidneys, lungs, skin, intestinal tract and brains of radiological terrorism victims. view more (2009-07-13)
Space radiation threats to astronauts addressed in federal research study
A better understanding of solar storms and how best to protect astronauts from space radiation is needed as NASA pushes toward manned missions to the moon and Mars in the coming decades, according to a new National Research Council report. view more (2006-10-26)
Intensity-modulated radiation therapy reduces side effects for cervical cancer
Preliminary results from a University of Pittsburgh study evaluating extended-field intensity-modulated radiation therapy (IMRT) for cervical cancer found that it resulted in significantly reduced side effects and outcomes comparable to standard radiotherapy. view more (2006-11-08)
New tool gives researchers a glimpse of biomolecules in motion
The ability of biomolecules to flex and bend is important for the performance of many functions within living cells. view more (2009-01-14)
Drug helps cognitive function in brain tumor patients after radiation
A drug that is marketed to treat Alzheimer's disease also improves cognitive function, mood and quality of life in brain tumor patients following radiation therapy. view more (2006-03-20)
Jefferson researchers find nanoparticle shows promise in reducing radiation side effects
Using transparent zebrafish embryos, researchers at Jefferson Medical College have shown that a microscopic nanoparticle can help fend off damage to normal tissue from radiation. view more (2005-11-15)
Hot Paper in the Biochemical Journal
DNA DAMAGE INSIGHT An exciting new paper from the Biochemical Journal regarding the phosphorylation state of LKB1 in response to ionising radiation can be viewed online as an Immediate Publication at www.BiochemJ.org (DOI: 10.1042/BJ20021284). Researchers at the University of Dundee, the University of Calgary and Tel Aviv University collaborated... view more... (2002-09-20)
PET imaging response a prognostic factor after thoracic radiation therapy for lung cancer
A rapid decline in metabolic activity on a PET scan after radiation therapy for non-small cell lung cancer is correlated with good local tumor control, according to a study presented by researchers at Thomas Jefferson University Hospital at the 51st ASTRO Annual Meeting. view more (2009-11-09)
Sun exposure may trigger certain autoimmune diseases in women
Ultraviolet (UV) radiation from sunlight may be associated with the development of certain autoimmune diseases, particularly in women. view more (2009-07-31)
Increasing radiation dose shortens treatment time for women who choose breast sparing treatment
Radiation therapy after lumpectomy for early-stage breast cancer can be safely delivered in higher daily doses to greatly reduce treatment time. view more (2007-05-30)
Taming Tiny, Unruly Waves for Nano Optics
Nanoscale devices present a unique challenge to any optical technology - there's just not enough room for light to travel in a straight line. view more (2007-10-09)
Measuring invisible reflections
The race is on for chip manufacturers. Many of them plan to open chip fabrication facilities employing extreme ultraviolet (EUV) radiation between up until 2010. This trend is being driven by advances in photolithography in which increasingly shorter wavelengths enable the production of even finer microelectronic structures. The result is higher... view more... (2003-07-25)
New technique measures chemical composition of tiny details
The method which the Eindhoven have developed is based on the radiation emitted by an object when it is irradiated by a beam of electrons. The measurable phenomenon occurs because the electrons in the beam collide with electrons in the atoms making up the object so that they enter an excited state. When the electrons return to the free state, with... view more... (2000-01-18)
Jefferson radiation oncologists use real-time system to plant 'seeds' against cancer
Radiation oncologists and urologists at the Kimmel Cancer Center at Jefferson and Thomas Jefferson University Hospital in Philadelphia have begun using a real-time system to implant radiation-emitting seeds in prostate cancer patients. view more (2007-09-24)
Columbia researchers: Growth of CT scan use may lead to significant public health problem
Computed Tomography (CT) scans are an increasingly used X-ray-based tool for providing a three-dimensional view of a particular organ or tissue. view more (2007-11-29)
Space-related radiation research could help reduce fractures in cancer survivors
A research project looking for ways to reduce bone loss in astronauts may yield methods of improving the bone health of cancer patients undergoing radiation treatment. view more (2009-09-16)
Research finds shorter-course radiation treatment safe for breast cancer
External-beam radiation therapy for early-stage breast cancer can be delivered safely and in a shorter course that eliminates as much as two weeks from conventional treatment. view more (2006-11-09)
Universe's oldest objects emerge from the background
The deepest reaches of space are permeated by a cloak of infrared radiation, an uneven energy swath generated by long-dead objects from the early universe. view more (2006-12-20)
