Study reveals zinc-regulated small compound in blood mediates harmful effects of zinc deprivation

According to new research published in The FASEB Journal, a drop in blood zinc levels does not directly harm the blood vessel cells. Rather, zinc regulates the production of a small molecular compound, which then circulates in the blood and causes harmful blood vessel cell effects.

Study to test ability of doxycycline dose to reduce growth of abdominal aortic aneurysms

A new clinical study at the University of Michigan Health System will test the ability of a once daily dose of doxycycline to reduce the growth of small abdominal aortic aneurysms.

Pulmonary hypertension may be caused by molecular pathway that damages blood vessels

Pulmonary hypertension, a deadly form of high blood pressure that develops in the lungs, may be caused by an inflammation-producing molecular pathway that damages the inner lining of blood vessels, according to a new study by researchers at the Stanford University School of Medicine.

Research findings may help scientists develop anthrax treatments for humans

Researchers at the National Institute of Allergy and Infectious Diseases and the National Heart, Lung, and Blood Institute, both part of the National Institutes of Health, have identified the cells in two distinct areas of the body that are simultaneously targeted for damage by anthrax toxins, eventually causing illness and sometimes death. Their findings, which appeared online today in Nature, are based on testing in mice.

Research finding could lead to potential treatment for lymphedema

The molecule interleukin-7 is an important immune messenger protein which ensures that a sufficient number of T cells are present in our body for immune defence. Researchers from ETH Zurich have now demonstrated that IL-7 has another important function: it enhances the drainage function of lymphatic vessels, which collect fluid that has leaked out of blood vessels into the body tissue and return it to the bloodstream.

Microscopic material in cells offers robust treatment for stroke

In the latest in a series of experiments testing the use of stem cells to treat neurological disease, researchers at Henry Ford Hospital have shown for the first time that microscopic material in the cells offers a "robust" treatment for crippling stroke.

Powerful new option for treating vasculitis

In a study published in the New England Journal of Medicine, a research consortium that includes the University of Alabama at Birmingham (UAB) has shown that a new drug for vasculitis, a potentially life-threatening auto-immune disease which causes inflammation in blood vessels, is as effective as standard therapy over 18 months.

Oxygen-generating compound could preserve muscle tissue after severe injury

The same compound in a common household clothes detergent shows promise as a treatment to preserve muscle tissue after severe injury. Researchers at the Wake Forest Baptist Medical Center's Institute for Regenerative Medicine hope the oxygen-generating compound could one day aid in saving and repairing limbs and tissue.

FDA approves Galderma's Mirvaso topical gel for facial erythema of rosacea

Galderma Laboratories, L.P. announced that the U.S. Food and Drug Administration has approved Mirvaso (brimonidine) topical gel, 0.33% for the topical treatment of the facial erythema (redness) of rosacea in adults 18 years of age or older. Applied once daily, Mirvaso works quickly to reduce the redness of rosacea and lasts up to 12 hours. Galderma expects Mirvaso to be available in pharmacies September 2013.

BSCs may offer new approach for reducing post-stroke cognitive dysfunction

Cognitive deficits following ischemic stroke are common and debilitating, even in the relatively few patients who are treated expeditiously so that clots are removed or dissolved rapidly and cerebral blood flow restored. A new study in Restorative Neurology and Neuroscience demonstrates that intracerebral injection of bone-marrow-derived mesenchymal stem cells reduces cognitive deficits produced by temporary occlusion of cerebral blood vessels in a rat model of stroke, suggesting that BSCs may offer a new approach for reducing post-stroke cognitive dysfunction.

Scientists grow cells that line blood vessels from human iPSCs

In a scientific first, Harvard Stem Cell Institute scientists have successfully grown the cells that line the blood vessels-called vascular endothelial cells-from human induced pluripotent stem cells (iPSCs), revealing new details about how these cells function.

In dynamic mind-body interaction, brain recruits cells from immune system to promote anxiety

New research shows that in a dynamic mind-body interaction during the interpretation of prolonged stress, cells from the immune system are recruited to the brain and promote symptoms of anxiety.

New drug-delivery strategy for central vision loss

Johns Hopkins biomedical engineers have teamed up with clinicians to create a new drug-delivery strategy for a type of central vision loss caused by blood vessel growth at the back of the eye, where such growth should not occur.
