Low Incidence Of Venous Insufficiency In MS
Date: Mar-11-2013Results of a study using several imaging methods showed that CCSVI (chronic cerebrospinal venous insufficiency) occurs at a low rate in both people with multiple sclerosis (MS) and non-MS volunteers, contrary to some previous studies. The research by an interdisciplinary team at The University of Texas Health Science Center at Houston (UTHealth) was published in a recent early online edition of the Annals of Neurology...
Mindfulness And Emotional Well-Being
Date: Mar-11-2013A new study from the University of Utah shows that individuals who describe themselves as being more mindful have more stable emotions and perceive themselves to have better control over their mood and behavior throughout the day. Higher mindful people also describe less cognitive and physiological activation before bedtime, suggesting that greater emotional stability during the day might even translate into better sleep. The study results will be presented later this month at the annual meeting of the American Psychosomatic Society...
Predicting Which Women Are Likely To Develop Preeclampsia In Pregnancy
Date: Mar-11-2013Pregnant women who have a reduced number of capillaries under their skin during pregnancy may be at heightened risk for preeclampsia, according to research being presented at the American College of Cardiology's 62nd Annual Scientific Session. Researchers say monitoring such changes in small blood vessels early in pregnancy may allow for medical intervention long before the potentially life-threatening condition occurs...
Molecular Switch Discovered That Turns On Self-Renewal Of Liver Damage
Date: Mar-11-2013The liver is one of the few organs in our body that can regenerate itself, but how it occurs is a biological mystery. New research from BRIC, University of Copenhagen and the Finsen Laboratory, Rigshospitalet, has identified a protein complex that acts as a molecular switch turning on a self-regeneration program in the liver. The protein complex furthermore fine tunes liver metabolism, allowing this to run efficiently in parallel with the tissue damage repair...
C. Elegans Helping To Find New Treatments For Alzheimer's Disease
Date: Mar-11-2013According to a 2012 World Health Organization report, over 35 million people worldwide currently have dementia, a number that is expected to double by 2030 (66 million) and triple by 2050 (115 million). Alzheimer's disease, the most common form of dementia, has no cure and there are currently only a handful of approved treatments that slow, but do not prevent, the progression of symptoms. New drug development, no matter the disease, is a slow, expensive, and risky process...
What Is Cardiovascular Disease? What Causes Cardiovascular Disease?
Date: Mar-11-2013Cardiovascular diseases include illnesses that involve the blood vessels (veins, arteries and capillaries) or the heart, or both - diseases that affect the cardiovascular system. The cardiovascular system, also called the circulatory system, is the system that moves blood throughout the human body. It is composed of the heart, arteries, veins, and capillaries. It transports oxygenated blood from the lungs and heart throughout the whole body through the arteries. Blood goes through the capillaries - vessels situated between the veins and arteries...
Global Management Of Anemia In Children On Dialysis
Date: Mar-10-2013Children on dialysis who have anemia and who require high doses of drugs to treat it have an increased risk of dying prematurely, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The findings provide new insights that may help improve the health of children with kidney failure. Many patients on dialysis develop anemia, which can be treated with erythropoesis stimulating agents (ESAs) to boost hemoglobin, the component of blood that transports oxygen throughout the body...
Natural Immune Defenses That Resist Viral Infection Are Only Turned On In Some Brain Cells
Date: Mar-10-2013Viruses often spread through the brain in patchwork patterns, infecting some cells but missing others. New research at Washington University School of Medicine in St. Louis helps explain why. The scientists showed that natural immune defenses that resist viral infection are turned on in some brain cells but switched off in others. "The cells that a pathogen infects can be a major determinant of the seriousness of brain infections," says senior author Michael Diamond, MD, PhD, professor of medicine...
Walking Program Improves Stroke Survivors' Lives
Date: Mar-10-2013Regular, brisk walking after having a stroke could help boost your physical fitness, mobility and quality of life, according to research in the American Heart Association journal Stroke. "Walking is a great way to get active after a stroke," said Carron Gordon, Ph.D., lead author of the study and a lecturer in the physical therapy department at University of the West Indies in Jamaica. "It's familiar, inexpensive, and it's something people could very easily get into...
Hemophilia Mystery Solved
Date: Mar-10-2013An Australian researcher has found the third and final missing piece in the genetic puzzle of an unusual form of hemophilia, more than 20 year after he discovered the first two pieces. Professor Merlin Crossley, of the University of New South Wales, and his international team studied the blood-clotting disorder, hemophilia B Leyden, which is unusual because symptoms improve after puberty...
