SLU scientists have identified the first gene regulating programmed cell death in plant embryos
A research team at the Swedish University of Agricultural Sciences, SLU, has succeeded in isolating a novel gene that regulates cell death in plant embryos. This is a world first. The team consists of scientists from the Department of Plant Biology and Forest Genetics, headed by Peter Bozhkov and Sara von Arnold. The team has discovered... view more... (2004-06-01)
Calls to doctor's office may delay stroke treatment
Calling a primary care doctor instead of 9-1-1 at the first sign of a stroke can delay patients from reaching an emergency room during the most critical period - the first three hours after onset of stroke symptoms. view more (2008-02-21)
INCREASED OPIOID USE AT END OF LIFE DOES NOT SHORTEN SURVIVAL (p 398)
Patients who receive increased doses of opioid at the end of their lives do not have shorter survival than those who receive no increases, concludes a research letter published in this week's issue of THE LANCET. Public and professional concern that the use of opioids for symptom control might shorten life prompted the study by Nigel Sykes and... view more... (2000-07-26)
Doctors over-estimate survival of terminally ill patients
Doctors tend to over-estimate the survival of terminally ill cancer patients, but become more accurate closer to the date of death, finds a study in this week's BMJ. Accurate prognoses are important so patients can plan for death. Researchers reviewed eight studies involving more than 1,500 patients over 30 years to assess the accuracy of... view more...

'Virtual autopsy' helps identify drowning as cause of death
"Virtual autopsy" performed with multidetector computed tomography (MDCT) can aid forensics teams in determining if a person has drowned, according to a study published in the June issue of Radiology. view more (2007-05-29)
Burnham Researchers Turn Cancer Friend into Cancer Foe
Burnham Institute for Medical Research today announced that scientists have created a peptide that binds to Bcl-2, a protein that protects cancer cells from programmed cell death, and converts it into a cancer cell killer. view more (2008-10-08)
Researchers describe mechanisms by which capon gene causes heart rhythm disturbances
research team from the Cedars-Sinai Heart Institute, Johns Hopkins University and China Medical University and Hospital in Taiwan have described for the first time the mechanisms by which variants of a specific gene, CAPON or NOS1AP, can disrupt normal heart rhythm. Until recently, CAPON was not even suspected of existing in heart tissue or... view more... (2008-03-04)
Altered sodium channel function linked to heart failure
The results of a study, using mice and heart muscle cells from rabbits, by researchers from Georg-August-University Göttingen, Germany, have provided a potential molecular explanation for the abnormally rapid heartbeats known as ventricular tachyarrhythmias (VTs) that can cause the sudden death associated with heart failure. view more (2006-11-27)
Few young competitive athletes survive sudden cardiac arrest
Cardiopulmonary resuscitation (CPR) and automated external defibrillators (AED's) had surprisingly little effect on the survival rates for young athletes who experience sudden cardiac arrest (SCA). view more (2006-06-21)
Multiple organ failure and malignant tumors main causes of death in ICU and hospital
Multiple organ failure is the main cause of death in intensive care units. A study published today in the journal Critical Care shows that the main risk factors for death in the intensive care unit are central nervous system failure and cardiovascular failure, and the most frequent cause of death is multiple organ failure. view more (2006-11-03)
Therapeutic peptide frees the protein p73 to kill tumor cells
The protein p53 suppresses tumor development by potently inducing tumor cell death, making it an obvious target for anticancer therapeutics. view more (2007-03-09)
Call for closer examination of 'brain death' as the end of life
The medical diagnosis of brain death is at odds with our traditional view of when death actually occurs. view more (2007-09-12)
AIDS surpasses black death as deadliest disease in history
In terms of illness and death, AIDS is worse than the Black Death of the 14th century. Ninety five per cent of new infections of HIV are in the world's poor countries and heterosexual transmission is responsible for most of these, reports Peter Lamptey, in this week's BMJ. view more (2002-01-23)
Physicists uncover new solution for cosmic collisions
It turns out that our math teachers were right: being able to solve problems without a calculator does come in handy in the "real" world. view more (2008-01-11)
Doctors are often strongly affected by patient deaths
Doctors are often powerfully affected by the deaths of patients for whom they care, and some may need emotional support, according to a study in this week's BMJ. Researchers at two teaching hospitals in the United States investigated the emotional reactions of 188 doctors who cared for 68 patients at the time of their death. Most doctors (74%)... view more...

Study reveals high death toll after severe urinary complications in men over 45
As many as one in four men admitted to hospital with acute urinary retention will die within a year, finds a study published on bmj.com today. view more (2007-11-12)
Heart failure treated 'in the brain'
Beta-blockers heal the heart via the brain when administered during heart failure, according to a new study by UCL (University College London). view more (2008-03-26)
Young athletes need dual screening tests for heart defects, study suggests
To best detect early signs of life-threatening heart defects in young athletes, screening programs should include both popular diagnostic tests, not just one of them, according to new research from heart experts at Johns Hopkins. view more (2009-11-16)
Quitting smoking reduces risk of death from coronary heart disease by more than a third
Research news from The Cochrane Library New evidence from The Cochrane Library indicates a 36% reduction in the risk of death for sufferers of coronary heart disease (CHD), simply by quitting smoking. Smoking is a proven contributor to death from CHD; 40% of heart disease cases in the UK are attributable to smoking. A number of studies have shown... view more... (2003-12-16)
Experts unveil new CVD guidelines and position papers
Several new guidelines and position papers offering the most up to date information to ensure that clinicians practice evidence-based medicine were released at the Canadian Cardiovascular Congress 2009 this week. view more (2009-10-28)
