UC Irvine study: Small amount of brain bleeding is common among older individuals

Neurologist Dr. Mark Fisher and neuropathologist Dr. Ronald Kim found that cerebral microbleeds are highly prevalent in the aging brain - and not primarily products of stroke-related injury, hypertension or neurodegenerative diseases such as Alzheimer's, as had been thought.

Highlights of Frontiers in Optics 2010/Laser Science XXVI Meeting

Scientists and engineers from around the world will gather on the shores of Lake Ontario in Rochester, N.Y. next week to discuss some of the latest breakthroughs in lasers and optics and their applications to cutting-edge science, the development of new materials, and medicine.

Pericytes regulate blood-brain barrier

While the blood-brain barrier (BBB) protects the brain from harmful chemicals occurring naturally in the blood, it also obstructs the transport of drugs to the brain. In an article in Nature scientists at the Swedish medical university Karolinska Institutet now present a potential solution to the problem. The key to the BBB is a cell-type in the blood vessel walls called pericytes, and the researchers hope that their findings will one day contribute to new therapies for diseases like Alzheimer's and stroke.

Scientists discover 'switch' mechanism of lymphatic and blood vessel cells

Scientists at the University of East Anglia have made an important breakthrough in the way anti-cancer drugs are tested. A tumour cannot grow to a large size or spread until it has developed its own blood supply and leading research has looked for a way of halting capillary formation to stop tumours taking hold.But new findings published today in the Journal of Cell Science have shown that scientists testing such treatments may not have been studying exactly what they thought they were.

Agilent's HPLC-Chip/MS technology helps identify over 200 different human milk oligosaccharides structures

Agilent Technologies Inc. today announced that a group of researchers from the University of California, Davis, has made a significant discovery: human breast milk contains an unexpected abundance of sugars that coats the lining of infants' intestines, protecting it from noxious bacteria. Results of the research, which used Agilent technology, were published in this month's Proceedings of the National Academy of Sciences of the United States of America.

CD31 positive cells have potential for treating peripheral artery disease: Research

Isolating cells from a patient's blood or bone marrow that nourish blood vessels may be a safer and less arduous route to treatment of cardiovascular disease than obtaining rare stem cells, according to research from Emory University School of Medicine. In recent clinical trials, doctors in several countries have tested the ability of a patient's bone marrow cells to repair damage, such as heart attacks and peripheral artery disease, created by problems of blood flow.

New findings show why some people suffer from high levels of triglycerides

New findings reported in the July issue of Cell Metabolism, a Cell Press publication, are offering new leads as to why some people might suffer from high levels of triglycerides. High triglycerides are a risk factor for atherosclerosis and cardiovascular disease. They can also lead to inflammation of the pancreas, the researchers said.

UAB receives $1.47M NHLBI grant to study red blood cell lesion

Researchers in the University of Alabama at Birmingham (UAB) departments of Pathology, Microbiology and Surgery have received a $1.47 million grant from the National Heart, Lung, and Blood Institute (NHLBI) to study so-called red blood cell lesion, a term given to the potentially harmful changes in red blood cells that have been stored for longer times after collection.

NHLBI funds nine research grants to determine safety and efficacy of red blood cell transfusions

The National Heart, Lung, and Blood Institute, part of the National Institutes of Health, is funding nine research grants to determine if the safety and efficacy of red blood cell transfusions vary depending on how long the cells have been stored. One of the grants supports the first large, multi-center, randomized clinical trial to compare outcomes in heart surgery patients who receive transfusions of red blood cells that have been stored for shorter or longer amounts of time.

Adult stem cell infusion during bypass surgery improves heart function: Study

Stem cell scientists from around the world gathered at the International Society of Stem Cell Research (ISSCR) in San Francisco to exchange information about the latest treatments with stem cells. An American company, TCA Cellular Therapy, LLC announced its FDA clinical trial results using adult stem cells in patients with history of a heart attack during open heart surgery.

Alexion's Soliris may benefit patients with thrombotic microangiopathy from uncontrolled complement activation

Researchers reported today that Soliris® (eculizumab), a first-in-class terminal complement inhibitor developed by Alexion Pharmaceuticals, Inc., may provide clinical benefits to patients with thrombotic microangiopathy (TMA) resulting from uncontrolled complement activation. TMA, the formation of blood clots in capillaries and small arteries, can lead to life-threatening damage in multiple organs including kidney failure, thrombocytopenia (abnormally low platelet count) and anemia.

Tiny cell bricks hold potential for building artificial tissue

Tissue engineering has long held promise for building new organs to replace damaged livers, blood vessels and other body parts. However, one major obstacle is getting cells grown in a lab dish to form 3-D shapes instead of flat layers.
