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)
Monash researchers lead the way in blood clotting discovery
A Monash-led research team has discovered an entirely new mechanism that promotes blood clot formation - a major breakthrough that will impact on treatment and prevention of heart disease and stroke. view more (2009-05-26)
Study explores cause of exercise intolerance in heart failure patients
A new study shows that blood flow to the legs is relatively normal in people with diastolic heart failure, suggesting other potential causes of their inability to do everyday activities. view more (2006-11-20)
Study Helps Explain Connection Between Sleep Apnea, Stroke And Death
Obstructive sleep apnea decreases blood flow to the brain, elevates blood pressure within the brain and eventually harms the brain's ability to modulate these changes and prevent damage to itself, according to a new study published by The American Physiological Society. view more (2009-01-06)
Monitoring Blood Flow Helps Improve Prostate Biopsies, Jefferson Researchers Report
Using a special ultrasound technique to spot areas of blood flow in the prostate gland may substantially reduce the number of unnecessary biopsies, according to a new study by urologists and radiologists at the Jefferson Prostate Diagnostic Center and the Kimmel Cancer Center at Jefferson in Philadelphia. view more (2008-05-27)
Brain starvation as we age appears to trigger Alzheimer's
A slow, chronic starvation of the brain as we age appears to be one of the major triggers of a biochemical process that causes some forms of Alzheimer's disease. view more (2008-12-29)
Backpack Straps Can Decrease Blood Flow In The Shoulder And Arm
More than 92 percent of the children in the U.S. carry backpacks. Typically the backpacks are loaded with almost one-fourth of the child's body weight (22 percent) and worn with only one strap. view more (2008-04-08)
Bone marrow cell therapy may be beneficial for patients with ischemic heart disease
The injection of bone marrow cells into the heart of patients with chronic myocardial ischemia (reduced blood flow to some areas of the heart) was associated with modest improvements in blood flow and function of the left ventricle. view more (2009-05-20)
Deciphering the limits to human maximal exercise performance
It has remained unknown during centuries what is the main factor limiting maximal exercise capacity in humans. During the past century evidence has accumulated suggesting that maximal exercise capacity in humans is limited by the maximal amount of O2 that can be delivered to the active muscles. A rather important step in this direction was the... view more... (2004-06-10)
Minimally invasive procedure restores blood flow to kidneys, research suggests
A pilot study suggests that the results of minimally invasive angioplasty and stenting to restore blood flow to the kidneys can be significantly improved if a suction device is used to remove the material blocking the vessel. view more (2006-07-05)
Detecting anthrax proteins at ultralow concentrations
A new laboratory method for quickly detecting active anthrax proteins within an infected blood sample at extremely low levels has been developed. view more (2005-08-29)
New study reveals components of cocoa may enhance the appearance of the skin
Cocoa butter has long been used topically in many skin creams and cosmetics because it is thought to be good for the skin. view more (2006-05-23)
Blood flow in brain takes a twist, affecting views of Alzheimer's
New findings that long-overlooked brain cells play an important role in regulating blood flow in the brain call into question one of the basic assumptions underlying today's most sophisticated brain imaging techniques and could open a new frontier when it comes to understanding Alzheimer's disease. view more (2006-01-06)
Brain Blood Flow Gives Clues to Treating Depression
The usefulness of established molecular imaging/nuclear medicine approaches in identifying the "hows" and "whys" of brain dysfunction and its potential in providing immediately useful information in treating depression are emphasized in a study in the August Journal of Nuclear Medicine. view more (2007-08-09)
Groundbreaking research highlights myriad health benefits of flavanol-rich cocoa
Research has demonstrated that consumption of naturally occurring compounds in cocoa can lead to a range of circulatory health benefits including the first observed brain and cardiovascular blood flow improvements. view more (2006-07-26)
Elevated nitric oxide in blood is key to high altitude function for Tibetans
How can some people live at high altitudes and thrive while others struggle to obtain enough oxygen to function? view more (2007-10-31)
Study: Added oxygen during stroke reduces brain tissue damage
Scientists have countered findings of previous clinical trials by showing that giving supplemental oxygen to animals during a stroke can reduce damage to brain tissue surrounding the clot. view more (2009-10-20)
Mesh-like Network of Arteries Adjusts to Restore Blood Flow to Stroke-Injured Brain
A grid of small arteries at the surface of the brain redirects flow and widens at critical points to restore blood supply to tissue starved of nutrients and oxygen following a stroke, a study published this week has found. view more (2009-02-02)
Titanium human “spare parts”
Heart valves bred from a patient’s own cells would be a big progress. Meanwhile, surgeons have to make do with other methods and materials: tissue grafts, modified heart valves from human or animal donors. Valves made from artificial materials have the advantage of lasting longer. But they have the unfortunate drawback to intensify the... view more... (2002-09-09)
Researchers uncover mechanisms leading to portal hypertension
A physician-scientist at UT Southwestern Medical Center and his research team have identified mechanisms causing a potentially deadly type of hypertension that results from liver damage-findings that could lead to its prevention. view more (2005-09-30)
