Large-Scale Computer Simulation Of Human Blood
5/04/2012
Having a virtual copy of a patient's blood in a computer would be a boon to researchers and doctors. They could examine a simulated heart attack caused by blood clotting in a diseased coronary artery and see if a drug like aspirin would be effective in reducing the size of such a clot...
For Patients With Multiple Myeloma, Low-Dose Whole-Body CT Finds Disease Missed On Standard Imaging
5/03/2012
Low dose whole body CT is nearly four times better than radiographic skeletal survey, the standard of care in the U.S., for determining the extent of disease in patients with multiple myeloma, a new study shows. The study, conducted at the University of Maryland in Baltimore, included 51 patients who had both a radiographic skeletal survey as well as a low dose whole body CT examination...
Lung Cancer Patients Benefit From Patient Education Video When Viewed Before Their Operation

A patient education process may provide an antidote to the emotional and physical difficulties that lung cancer patients face before and after an operation, according to a new study published in the May issue of the Journal of the American College of Surgeons...
Stunning Inner Space Observations Could Impact Treatment Of Down Syndrome, Lissencephaly Or Cancer
5/03/2012
Scientists using high-powered microscopes have made a stunning observation of the architecture within a cell - and identified for the first time how the architecture changes during the formation of gametes, also known as sex cells, in order to successfully complete the process...
"Ex Vivo" Surgery Enables Removal Of Previously Inoperable Tumors Of The Abdomen
5/03/2012
Abdominal tumors involving both roots of the celiac and superior mesenteric artery (SMA) are deemed unresectable by conventional surgical methods, as removal would cause necrosis of the organs that are supplied by those blood vessels...
New Clues To How Brain Cancer Cells Migrate And Invade
5/03/2012
Researchers have discovered that a protein that transports sodium, potassium and chloride may hold clues to how glioblastoma, the most common and deadliest type of brain cancer, moves and invades nearby healthy brain tissue...
The Risks Of Low-Level Radiation Highlighted By Experts
5/03/2012
Each time a release of radioactivity occurs, questions arise and debates unfold on the health risks at low doses - and still, just over a year after the disaster at the Fukushima Nuclear Power Station, unanswered questions and unsettled debates remain...
Study Lends Support To Safe Use For Adult-Derived Human Stem Cell Therapy
5/03/2012
A team of researchers from Johns Hopkins University and the National Human Genome Research Institute has evaluated the whole genomic sequence of stem cells derived from human bone marrow cells - so-called induced pluripotent stem (iPS) cells - and found that relatively few genetic changes occur during stem cell conversion by an improved method...
In Postmenopausal Women, Weight Loss Led To Reduction In Inflammation

Postmenopausal women who were overweight or obese and lost at least 5 percent of their body weight had a measurable reduction in markers of inflammation, according to a study published in Cancer Research, a journal of the American Association for Cancer Research...
After Breast Lumpectomy Brachytherapy Linked To More Complications Than Whole-Breast Irradiation
5/02/2012
A study in the May 2 edition of JAMA reveals that older women with invasive breast cancer who were treated with brachytherapy after lumpectomy were more likely to develop complications and had a lower risk of long-term breast preservation than women who received whole-breast irradiation, however, there was no difference in overall survival...
