Following Northern Ireland Executive?s decision to implement the independent Pay Review Body?s recommendation of a 2.5% pay award for nurses in full, backdated to 1 April 2007, Dr Peter Carter, General Secretary of the RCN, said:
Biologists have long thought that a simple on/off switch controls most genes in human cells. Flip the switch and a cell starts or stops producing a particular protein. But new evidence suggests that this model is too simple and that our genes are more ready for action than previously thought.
Bringing together the high-quality 3D images of MRI with the intense tumor-killing x-rays of a linear accelerator, scientists at the Alberta Cancer Board are building a prototype that could for the first time enable powerful x-ray beams to become a viable treatment option for liver, stomach and pancreatic cancers, which currently must be treated with surgery, drugs, or internal radioactive seeds in most cases.
Using innovative physics, researchers have proposed a system that may one day bring proton therapy, a state-of-the-art cancer treatment method currently available only at a handful of centers, to radiation treatment centers and cancer patients everywhere.
Measuring levels of a chemical found in blood offers the best indicator yet of the amount of fat surrounding abdominal organs, according to a new study of lean and obese individuals reported in the July issue of Cell Metabolism, a publication of Cell Press.
A Canadian clinical case study indicated the potential dangers of using portable CD and MP3 players, iPods in rains and thunderstorms, published in Wednesday’s issue of New England Journal of Medicine.
A daily pinta or a helping of dairy foods protect against the clustering of abnormal body chemistry known as the metabolic syndrome, suggests a study in the Journal of Epidemiology and Community Health .
