Study questions risks of anti-bleeding drug during heart surgery
Contrary to recent studies, proper use of a drug called aprotinin to reduce bleeding during heart surgery does not increase the risk of heart attack or stroke, according to a study in the June issue of The Journal of Thoracic and Cardiovascular Surgery. view more (2007-05-30)
Methane bacteria possess pressure valve
Microbiologists from the University of Nijmegen have discovered that a methane-forming archaeabacterium sometimes deliberately allows hydrogen ions to leak out of its cell. At high hydrogen concentrations in particular, the cell membrane works as a sort of pressure valve. The waste of energy seems to be of vital importance for the microorganism.... view more...

Cardiac arrest resuscitation: Passive oxygen flow better than assisted ventilation
Arizona researchers have added another piece to the mounting body of evidence that suggests during resuscitation efforts to treat patients in cardiac arrest, "passive ventilation" significantly increases survival rates, compared to the widely practiced "assisted ventilation." view more (2009-08-12)
Nanotube, heal thyself
Pound for pound, carbon nanotubes are stronger and lighter than steel, but unlike other materials, the miniscule cylinders of carbon - which are no wider than a strand of DNA - remain remarkably robust even when chunks of their bodies are blasted away with heat or radiation. view more (2007-02-16)
Boosting lung power - the key to athletic success
As the England team celebrates success in the Commonwealth Games, UK scientists are developing new technologies that could further boost athletes' performances by training their breathing muscles. The muscles that draw air into our lungs are crucial to ensuring that the rest of the body receives a good supply of oxygen-rich blood - yet these... view more... (2002-08-05)
Nasal plastic surgery improves airway function
Nasal plastic surgery appears to improve nasal airway function in patients with severe nasal obstructions. view more (2006-09-19)
A simple, noninvasive test measures survival time in adult pulmonary hypertension
Researchers have developed a simple, noninvasive way to measure right ventricular function in the heart to predict survival of adults who suffer from pulmonary hypertension. view more (2006-11-01)
Low-risk balloon trip to the heart
Patients who are at high-risk of having a heart attack or who require a bypass must undergo a coronary angiography. A new balloon catheter, being presented at the MEDTEC exhibition, allows this to be done more swiftly, more easily and with less risk than previous examinations. Calcium and cholesterol can block coronary blood vessels. The thicker... view more... (2002-03-05)
Nasal surgery creates feminine profiles in male-to-female transsexuals
Nasal surgery appears to effectively create feminine facial profiles in patients undergoing male-to-female gender reassignment, according to a report in the September/October issue of Archives of Facial Plastic Surgery, one of the JAMA/Archives journals. view more (2007-09-18)
Radical engine redesign would reduce pollution, oil consumption
Researchers have created the first computational model to track engine performance from one combustion cycle to the next for a new type of engine that could dramatically reduce oil consumption and the emission of global-warming pollutants. view more (2007-05-11)
A breakthrough in heat transfer technology
A revolutionary breakthrough in heat transfer technology that could improve process productivity and reduce energy consumption and waste, is being developed by Ashe Morris Ltd thanks to a £100,000 investment from NESTA (the National Endowment for Science, Technology & the Arts), the largest source of early stage funding in the UK. view more (2003-07-21)
Holiday season could ring in 'heartburn season'
Making merry is often synonymous with overindulging - whether from holiday feasts or rich desserts or alcoholic beverages - ringing in the holiday season as "heartburn season." view more (2006-11-16)
Patients dying while waiting for bypass operation-many could be saved
A dissertation from the Sahlgrenska Academy at Göteborg University in Sweden shows that 1.3 percent of those waiting for a bypass operation die waiting. Many more patients would survive if high risk cases were given top priority. Diseases of the coronary artery are the most common cause of death in the world. Surgery of the coronary artery,... view more... (2005-03-04)
Sticky surfaces turn slippery with the flip of a molecular light switch
Changing a surface from sticky to slippery could now be as easy as flipping a molecular light switch. view more (2006-06-20)
NewYork-Presbyterian/Columbia leads research into robotic surgery for kidney cancer
Clinical research at NewYork-Presbyterian Hospital/Columbia University Medical Center is helping bring the advantages of robotic surgery, including reduced pain and quicker recovery, to kidney cancer patients. view more (2008-07-29)
Octogenarians can be good candidates for heart surgery
Patients 80 years and older who are in overall good health are perfectly able to withstand open-heart surgery, according to the latest study of Dr. Kevin Lachapelle of the McGill University Health Centre (MUHC). His findings were presented this morning in Toronto during the 2008 Canadian Cardiovascular Congress. view more (2008-10-29)

Vitamin K discovery may lead to new treatments for patients at risk from blood clots
Medical Research Council (MRC) scientists have discovered more about the role that vitamin K plays in the complicated process of how blood clots. Their work, published in Nature, may lead to new treatments for patients at risk from blood clots, including those who have had heart attacks, have coronary artery disease, irregular heart beats, or have... view more...

Flower power
A plastic "energy flower'' that collects solar and wind energy that can then be used to power appliances in the home for free has won a Northumbria University student a top award. Paul Richardson, a third year design student, won a £1,750 Design International Attachment Award from the RSA (Royal Society for the encouragement of Arts,... view more... (2002-05-24)
