| BONN SCIENTISTS DISCOVER NEW HEMOGLOBIN TYPE. INSTRUMENTS FALSELY REPORT ANOXIA IN AFFECTED PEOPLE. |
| Scientists at the University of Bonn have discovered a new rare type of haemo-globin. Haemoglobin transports oxygen in the red blood corpuscles. When bound to oxygen it changes colour. The new haemoglobin type appears optically to be transporting little oxygen. Measurements of the blood oxygen level therefore present a similar picture to patients suffering from an inherited cardiac defect. |

| NEW UNDERSTANDING OF WHY BRAIN CELLS DIE AFTER STROKE WILL LEAD TO DEVELOPMENT OF NEW TREATMENTS |
| Scientists at Toronto Western Hospital and the University of Toronto have found a major mechanism that causes brain cells to die from stroke. They discovered that when brain cells are deprived of oxygen and vital nutrients, as happens to parts of the brain affected by a stroke, a special channel on the surface of those brain cells is activated, triggering a lethal chain reaction. The channel, called TRPM7, when activated causes brain cells to produce large quantities of free radicals – toxic molecules that break down the cell's DNA, proteins, and other components. Free radicals also cause TRPM7 to become even more active, causing massive overproduction of free radicals, resulting in death of the brain cell. |

| VASCULAR DISEASE AND AGING |
| Vascular disease pertains to the disorders that affect our arteries and veins. For the three most common types of vascular disease --carotid, aortic and peripheral – aging is a major risk factor. Recent studies suggest that pathological changes not only predispose the vasculature to disease but also impair compensatory adaptations to various stimuli including shear force and injury. Other studies have demonstrated a progressive increase in oxidative stress, activation of inflammatory mediators, and increasing endothelial dysfunction in both humans and animals. |

|
| ADULT BONE MARROW STEM CELLS CAN BECOME BLOOD VESSELS |
| Researchers at the University of Minnesota Stem Cell Institute (SCI) have demonstrated, for the first time, the ability of adult bone marrow stem cells to expand in vitro as endothelial cells (which line blood- and lymphatic vessels) and then engraft in vivo and contribute to new growth of blood vessels (neoangiogenesis). The findings will be published in the February 1, 2002 issue of the Journal of Clinical Investigation. |
