Combination therapy shows improvement for breast cancer patients
Giving radiation therapy and chemotherapy at the same time after a lumpectomy helps keep breast cancer from returning locally. view more (2006-12-01)
Iterative reconstruction technique significantly reduces patient radiation dose during CT scans
Computed tomography (CT) scans are responsible for more than two thirds of the total radiation dose associated with medical imaging exams. view more (2009-08-19)
Tackling the threat of nuclear terrorism
The only effective way to tackle the threat of nuclear terrorism is to abolish nuclear weapons and establish strict international control of all fissile materials that could be used to make new weapons, argue three US physicians in this week's BMJ. In the aftermath of 11 September 2001, nuclear terrorism has emerged as a real threat and could... view more... (2002-02-06)
Combination therapy reduces tumor resistance to radiation
Radiation is used to treat a variety of tumors and the response of tumors to radiation is dependent on endothelial cell death, which in turn limits oxygen delivery to the tumor, causing hypoxia and tumor cell death. view more (2007-06-08)
Largest PSA bounce study eases worry of prostate cancer returning
Prostate cancer patients who have a temporary rise in their prostate specific antigen (PSA) levels after radiation therapy-called a PSA bounce-are not at an increased risk of their cancer coming back any more than those who don't have a temporary rise. view more (2006-11-09)
Patent Granted For A Chemical Compound That Acts As A Molecular Switch
The University Jaume I (UJI), together with researchers from the CSIC and the Universitat Polite'cnica de Vale'ncia, has patented a new compound whose physico-chemical characteristics open up a wide range of technological applications. The compound is one of the metallodendrimers, which are molecules that undergo reversible changes in their... view more... (2004-06-30)
Cancer Gene Radiation Therapy Discovery
Dr Tracy Robson, a lecturer in molecular radiation science at the University's Jordanstown campus, has isolated a novel gene, called DIR-1, which can alter a tumour cell's susceptibility to radiation therapy. view more (1999-09-20)
Hydrocarbons in the Horsehead mane
Observing the edge of the famous Horsehead Nebula with the IRAM interferometer located on the Plateau de Bures (France), a team of French and Spanish astronomers discovered a large quantity of small hydrocarbon molecules. This is a surprise because the intense UV radiation illuminating the Nebula should destroy the small hydrocarbons near the... view more... (2005-02-21)
Experimental agents may prevent radiation-induced leukemia
Treatment with biphosphonates could prevent radiation-induced leukemia, according to data presented at the American Association for Cancer Research 100th Annual Meeting 2009. view more (2009-04-20)
Towards predicting late-stage radiation toxicity
Radiation is a brutal and in many cases necessary part of cancer therapy. More 50% of cancer patients receive radiotherapy as part of their treatment, and many experience concurrent negative side effects. view more (2006-10-31)
University Scientists Will Not See the Eclipse...At Least, Not With Their Eyes!
The sun constantly radiates energy across the spectrum of frequencies from radio, through heat, to visible light and beyond. During the period of totality, only radiation present in the sun's annular corona will be detectable, with energy directly radiated from the sun being masked by the moon. view more (1999-08-06)
Patients regain cognitive function after radiation for brain tumors
Patients who suffer from low-grade brain tumors are able to regain normal cognitive function after receiving radiation therapy to shrink their tumor. view more (2005-11-16)
Order of chemotherapy, radiation has no effect on breast cancer survival
For women who have had surgery for early breast cancer, it may not matter whether they receive follow-up chemotherapy before, after or during radiation therapy, according to a new review of studies. view more (2006-10-31)
Changing climate may make 'super weed' even more powerful
Researchers at the University of Delaware have discovered a new reason why the tall, tasseled reed Phragmites australis is one of the most invasive plants in the United States. view more (2009-06-04)
Multi-wavelength images help astronomers study star birth, death
In recent years, a number of ground-based optical and radio surveys of the Large and Small Magellanic Clouds - Earth's nearest neighboring galaxies - have become available. view more (2006-01-12)
40 Years of Research with Synchrotron Radiation at DESY
On Wednesday, May 19, starting at 1.30 p.m., the DESY research center will celebrate the anniversary of a very special kind of light: For 40 years, scientists have been conducting research with so-called synchrotron radiation at DESY - i.e. light with exceptional properties generated at accelerators. "The first measurements with the light... view more... (2004-05-19)
Radiation dose reduction in liver cancer
A new digital angiography flat panel system reduces the radiation dose to patients undergoing interventional treatment for liver cancer by about one-fourth, a new study shows. view more (2005-10-03)
Modern radiation therapy ups lung cancer survival
Modern three-dimensional radiation therapy has been proven to be more successful at curing lung cancer than older two-dimensional radiation therapy for some patients with early stage lung cancer. view more (2006-09-01)
Jefferson researchers show chemotherapy and radiation together extend lung cancer patients' lives
Chemotherapy given at the same time as radiation therapy can help patients with a certain type of lung cancer live nearly 50 percent longer than they might have otherwise if the same treatment was given differently, according to an international team's analysis of several trial results. view more (2007-11-12)
Making waves in cancer detection
We`re all familiar with X-rays being used to look inside our bodies. But according to physicists, medical imaging in the future is likely to be based on an as yet unused type of radiation known as terahertz radiation. view more (2002-07-23)
