UCLA researchers who analyzed dozens of previously unexamined internal documents from the tobacco industry say tobacco companies developed "deep and intimate" knowledge about the cancer-causing potential of radioactive alpha particles in cigarette smoke but deliberately kept it from the public for more than four decades...
HPV Vaccine Less Likely To Be Recommend By Pediatricians In Appalachia
9/29/2011
Pediatricians in Appalachia are less likely than doctors in other areas to encourage parents to have their children receive the human papillomavirus (HPV) vaccine, according to a new study...
Pump Action Shut Down To Break Breast Cancer Cells' Drug Resistance
9/29/2011
Breast cancer cells that mutate to resist drug treatment survive by establishing tiny pumps on their surface that reject the drugs as they penetrate the cell membrane - making the cancer insensitive to chemotherapy drugs even after repeated use...
Pre-clinical Research Proves Promising For The Treatment Of Blood Cancer
9/29/2011
Pre-clinical research has generated some very promising findings about a prototype drug for the treatment of chronic lymphocytic leukemia (CLL). The findings, from work carried out by scientists at NUI Galway, are published in this month's Molecular Cancer Therapeutics, a journal of the American Association for Cancer Research...
Fluke Worm 'Cell Death' Discovery Could Lead To New Drugs For Deadly Parasite
9/29/2011
Researchers from the Walter and Eliza Hall Institute have for the first time identified a 'programmed cell death' pathway in parasitic worms that could one day lead to new treatments for one of the world's most serious and prevalent diseases. Dr Erinna Lee and Dr Doug Fairlie from the institute's Structural Biology division study programmed cell death (also called apoptosis) in human cells...
Tobacco Companies Knew Radioactive Particles In Cigarette Posed Cancer Risk But Kept Quiet
9/29/2011
Tobacco companies knew that cigarette smoke contained radioactive alpha particles for more than four decades and developed "deep and intimate" knowledge of these particles' cancer-causing potential, but they deliberately kept their findings from the public, according to a new study by UCLA researchers...
How Normal Cells Become Brain Cancers
9/29/2011
Brain tumor specimens taken from neurosurgery cases at the University of California, San Francisco (UCSF) Medical Center has given scientists a new window on the transformation that occurs as healthy brain cells begin to form tumors. The work may help identify new drugs to target oligodendroglioma, a common type of brain tumor, at its earliest stage, when it is generally most treatable...
Modern Shift Work Pattern Potentially Less Harmful To Health
9/29/2011
Recent research suggests that the modern day-day-night-night shift pattern for shift workers may not be as disruptive or as potentially carcinogenic as older, more extreme shift patterns...
Mammographic Surveillance Increases Breast Cancer Survival
9/29/2011
New research published in Health Technology Assessment 2011; vol. 15:34 has found that surveillance using mammography increases the survival chances of breast cancer patients. The research was funded by the National Institute for Health Research Health Technology Assessment (NIHR HTA) programme. Around 45,000 women are diagnosed with breast cancer in the UK every year...
Reducing Tumour Growth By Treating Common Virus
9/29/2011
Researchers at Karolinska Institutet in Sweden have demonstrated for the first time that it is possible to inhibit the growth of brain tumours by treating the common Cytomegalovirus (CMV). The virus, which is found in a wide range of tumour types, offers a possible route towards controlling tumour growth and reducing the size of the tumour as a complement to conventional cytotoxin-based therapies...
