New Technique For Measuring Blood Flow To Brain In Babies (p 1749)
Authors of a research letter in this week's issue of THE LANCET describe how an ultrasound technique can be used as a non-invasive way of measuring blood flow to the brain in babies, which may be of benefit to infants with brain disorders arising from restrictions in cerebral blood flow. Changes in the rate of blood flow to the brain in premature... view more... (2002-11-27)
Monitoring of blood flow to the brain could prevent brain damage
University of Southampton engineers believe that monitoring blood flow to the brains of head injury patients could potentially reduce the incidence of brain damage and long-term disability, and are developing methods of using ultrasound to do this. With many years experience in studying the rise and fall of pressure inside the heads of patients... view more... (2003-04-30)
Late life depression associated with blood flow changes in the brain
Depression in later life seems to be associated with changes in blood flow velocity in the main arteries of the brain, shows research in the Journal of Neurology Neurosurgery and Psychiatry. Hardened and thickened arteries, which are more typical in later life, do not explain the findings. view more (2002-06-25)
Brain Research To Help In Fight Against Cardiovascular Disease
Scientists at the University of Liverpool, supported by the British Heart Foundation, are studying blood flow in the brain to further medical understanding of cardiovascular disease. view more (2005-03-21)
Endurance Athletes Could Benefit From Surgical Release Of Kinked Leg Arteries (p 466)
Flow restrictions in leg arteries of endurance athletes are commonly caused by kinking and could be easily resolved by a straightforward surgical procedure, conclude authors of a study in this week's issue of THE LANCET. Endurance athletes-especially cyclists and speed skaters-often have restrictions in blood flow in their iliac arteries (the... view more... (2002-02-06)
Blood flow to brain may be clue to certain dementias
The amount of blood flowing into the brain may play a larger role in the development of dementia than previously believed, according to a study in the September issue of the journal Radiology. view more (2005-08-30)
Scientists find how neural activity spurs blood flow in the brain
New research from Harvard University neuroscientists has pinpointed exactly how neural activity boosts blood flow to the brain. The finding has important implications for our understanding of common brain imaging techniques such as fMRI, which uses blood flow in the brain as a proxy for neural activity. view more (2008-06-26)
St. Joseph's Hospital in Phoenix offers special test for children with stroke risk
Children's Rehabilitative Services (CRS) at St. Joseph's Children's Health Center in Phoenix is using a special ultrasound to identify the risk for stroke in children who have sickle cell disease. view more (2006-01-31)
Smoking damages the placenta and reduces foetal growth
Dr Peter Hindmarsh (University College, London), at the British Endocrine Societies 2003 meeting, will reveal new evidence that smoking when pregnant causes damage to the placenta and reduced birth weight. His team found that nutrient delivery to the baby was restricted and levels of an important developmental hormone, IGF-1, were reduced, causing... view more... (2003-03-19)
'Lite' low tar cigarettes impair blood flow as much as regular cigarettes
Low tar "lite" cigarettes impair blood flow through the heart as severely as regular cigarettes, reveals a small study published ahead of print in the journal Heart. view more (2007-05-15)
Scanning blood flow during operations
EUREKA project E! 2427 PERMON is developing a radiological imaging system that will give medics a clearer view inside the human body by accurately monitoring organ blood flow during operations. This essential information will lead to an increase in techniques such as laser surgery over more invasive methods. Operations will be less costly and less... view more... (2004-06-01)
Penn Research Team Tests Bedside Monitoring of Brain Blood Flow and Metabolism in Stroke Victims
A University of Pennsylvania team has completed the first successful demonstration of a noninvasive optical device to monitor cerebral blood flow in patients with acute stroke, a leading cause of disability and death. view more (2009-03-03)
Statins may improve circulation in the retina
The cholesterol-lowering medications known as statins may improve circulation in the eye, potentially reducing the risk of certain eye diseases. view more (2006-05-09)
How blood flow dictates gene expression
Researchers at the University of Pennsylvania School of Medicine have pinpointed a key regulatory protein that translates blood flow into gene expression. view more (2006-12-21)
Study: Even occasional smoking can impair arteries
Even occasional cigarette smoking can impair the functioning of your arteries, according to a new University of Georgia study that used ultrasound to measure how the arteries of young, healthy adults respond to changes in blood flow. view more (2008-10-08)
Constipation in women linked to anxiety, depression, and feeling "unfeminine"
Chronic constipation in some women is linked to anxiety, depression, and feeling "unfeminine," suggests a study in Gut. Researchers from St Mark's Hospital, Middlesex, studied 34 women between the ages of 19 and 45 who had suffered from constipation for five years or more. The study group was then compared with women who had no history... view more... (2001-07-11)
Opening a channel for salt retention
A research team has developed the first small molecule that can reversibly activate a key protein involved in balancing sodium levels, paving the way for drugs that can treat low blood pressure and related conditions. view more (2008-04-28)
Massage after exercise myth busted by Queen's research team
A Queen's University research team has blown open the myth that massage after exercise improves circulation to the muscle and assists in the removal of lactic acid and other waste products. view more (2009-05-08)
Novel computer model for blood flow could help doctors predict arterial disease
A unique computer model of how blood flows in human arteries has been developed by researchers in the UK. The model could help doctors understand the stresses that blood places on the walls of vessels and provide new insights into vascular disease. The work has been carried out by Dr Yun Xu together with Dr Simon Thom and Professor Alun Hughes at... view more... (2000-10-19)
Research finds older women who are more physically fit have better cognitive function
New research published in the international journal Neurobiology of Aging by Marc Poulin, PhD, DPhil, finds that being physically fit helps the brain function at the top of its game. view more (2009-01-09)
