Genetic Test May Help Tailor Cancer Treatment For Children
3/29/2012
A study led by Dr Janet Shipley from The Institute of Cancer Research (ICR) in London in collaboration with Dr Mauro Delorenzi from the SIB Swiss Institute of Bioinformatics in Lausanne has shown that a simple genetic test could help predict the aggressiveness of rhabdomyosarcoma tumours in children...
Long-Term Memory May Be Improved By Blocking 'Oh-Glick-Nack'
3/29/2012
Just as the familiar sugar in food can be bad for the teeth and waistline, another sugar has been implicated as a health menace and blocking its action may have benefits that include improving long-term memory in older people and treating cancer...
Pre-Cancerous Polyps May Be Hidden When Bowel Prep Inadequate Prior To Colonoscopy
3/29/2012
What happens on the day before a colonoscopy may be just as important as the colon-screening test itself. Gastroenterologists at Washington University School of Medicine in St. Louis have found that when patients don't adequately prep for the test by cleansing their colons, doctors often can't see potentially dangerous pre-cancerous lesions...
Taxane Chemotherapy Resistance Seen In Some Breast Cancer Tumors
3/29/2012
Some breast cancer tumours may be resistant to a common chemotherapy treatment, suggests recent medical research at the University of Alberta. Principal investigator Ing Swie Goping and her team discovered some breast cancer tumours had low levels of certain genes, and that those tumours didn't respond well to taxane chemotherapy, a common treatment used in breast cancer...
Prostate Cancer And Androgen Suppression
3/28/2012
Androgen suppression - the inhibition of testosterone and other male hormones - is a routine therapy for prostate cancer. Unfortunately, it can dramatically reduce the quality of patients' sex lives and, more importantly, lead to cancer recurrence in a more deadly androgen-independent form...
Nanoparticles, Magnetic Current Used To Damage Cancerous Cells In Mice
3/28/2012
Using nanoparticles and alternating magnetic fields, University of Georgia scientists have found that head and neck cancerous tumor cells in mice can be killed in half an hour without harming healthy cells...
Antibody Shrinks Tumors Of Seven Cancers
3/28/2012
A single antibody caused tumors from seven different human cancers transplanted into mice to shrink or disappear, according to a new study led by Stanford University School of Medicine in the US. The researchers hope to repeat this dramatic finding with tests in humans within the next two years...
Cellular Automation Model Created To Study Complex Tumor-Host Role In Cancer
3/28/2012
Cancer remains a medical mystery - despite all of the research efforts devoted to understanding and controlling it. The most sought-after tumor model is one that would be able to formulate theoretical and computational tools to predict cancer progression and propose individual treatment strategies...
Small Number Of Cancer Cells Detectable Using Photoacoustics Technique
3/28/2012
Researchers have developed multiple techniques and procedures to detect cancer cells during the earliest stages of the disease or after treatment. But one of the major limitations of these technologies is their inability to detect the presence of only a few cancer cells...
Game Theory Improves Understanding Of The Physics Of Cancer Propagation
3/28/2012
In search of a different perspective on the physics of cancer, Princeton University and University of California, San Francisco researchers teamed up to use game theory to look for simplicity within the complexity of the dynamics of cooperator and cheater cells under metabolic stress conditions and high spatial heterogeneity...
