(Medical Xpress)—Pharmacy researchers at the University of Florida have isolated a new marine compound they believe may lead to improved drug therapies for pulmonary diseases by inhibiting their progression rather than managing their symptoms. http://medicalxpress.com/news/2013-02-marine-compound-discovery-drug-treatment.html Diseases, Conditions, Syndromes Thu, 28 Feb 2013 09:20:02 EST news281262909 In a London ceremony today, Wyss Founding Director Don Ingber, M.D., Ph.D., received the NC3Rs 3Rs Prize from the UK's National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) for his innovative Lung-on-a-Chip—a microdevice lined by human cells that recapitulates complex functions of the living lung. http://medicalxpress.com/news/2013-02-lung-on-a-chip-prize-potentially-animal.html Medical research Tue, 26 Feb 2013 11:38:21 EST news281101092 Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have mimicked pulmonary edema in a microchip lined by living human cells, as reported today in the journal Science Translational Medicine. They used this "lung-on-a-chip" to study drug toxicity and identify potential new therapies to prevent this life-threatening condition. http://medicalxpress.com/news/2012-11-lung-on-a-chip-stage-animal.html Medical research Wed, 07 Nov 2012 14:00:04 EST news271508128 Shelly Peyton, a chemical engineer at the University of Massachusetts Amherst, says scientists know that breast cancer will spread to many different types of tissues in the body, and that this migration is the key reason the cancer is deadly. What they don't know is why some forms of the cancer move to the brain, while others seek out bone or lung tissues. http://medicalxpress.com/news/2012-10-chemical-breast-cancer-bone-brain.html Cancer Wed, 03 Oct 2012 07:46:01 EST news268469114 When autologous (self-donated) lung-derived mensenchymal stem cells (LMSCs) were transplanted endoscopically into 13 adult female sheep modeled with emphysema, post-transplant evaluation showed evidence of tissue regeneration with increased blood perfusion and extra cellular matrix content. Researchers concluded that their approach could represent a practical alternative to conventional stem cell-based therapy for treating emphysema. http://medicalxpress.com/news/2012-06-cell-transplantation-lung-stem-cells.html Medical research Mon, 04 Jun 2012 15:30:33 EST news258042494 Flax has been part of human history for well over 30,000 years, used for weaving cloth, feeding people and animals, and even making paint. Now, researchers from the Perelman School of Medicine at the University of Pennsylvania have discovered that it might have a new use for the 21st century: protecting healthy tissues and organs from the harmful effects of radiation. In a study just published in BMC Cancer, researchers found that a diet of flaxseed given to mice not only protects lung tissues before exposure to radiation, but can also significantly reduce damage after exposure occurs. http://medicalxpress.com/news/2011-08-ancient-crop-effective-21st-century.html Cancer Tue, 09 Aug 2011 11:24:12 EST news232107792 For the first time, researchers at Brigham and Women's Hospital (BWH) have identified a human lung stem cell that is self-renewing and capable of forming and integrating multiple biological structures of the lung including bronchioles, alveoli and pulmonary vessels. This research is published in the May 12, 2011 issue of the New England Journal of Medicine. http://medicalxpress.com/news/2011-05-human-lung-stem-cell.html Medical research Wed, 11 May 2011 17:20:58 EST news224353212
