Migraine is a neurological, not vascular, disorder

The latest genetic and biological research shows that migraine is a neurological, not vascular, disorder and both acute and preventive treatments being developed target peripheral and central nervous systems, according to a prominent migraine expert addressing the American Pain Society (APS)today.

Scientists investigate how ApoE4 gene contributes to Alzheimer's disease

A well-known genetic risk factor for Alzheimer's disease triggers a cascade of signaling that ultimately results in leaky blood vessels in the brain, allowing toxic substances to pour into brain tissue in large amounts, scientists report May 16 in the journal Nature.

Apigenin effective against human breast cancer

Apigenin, a natural substance found in grocery store produce aisles, shows promise as a non-toxic treatment for an aggressive form of human breast cancer, following a new study at the University of Missouri.

NeuroSigma Subsidiary sees potential for Thin-Film Nitinol in next-generation flow-diverting stents for treating intracranial aneurysms

NeuroSigma, Inc., a Los Angeles-based medical device company, today announced that its majority-owned subsidiary, NSVascular, Inc. (NSV), acquired a portfolio of patents and related trade secrets covering the fabrication of Thin-Film Nitinol (TFN) from TiNi Alloy Company, including U.S. Patent No. 6,746,890 entitled “Three Dimensional Thin Film Devices and Methods of Fabrication,” an important piece of the portfolio covering the production of three-dimensional TFN constructs.

African-Americans with scleroderma have more antibodies linked to severe complications

A new analysis finds that compared to Caucasians, African-Americans with systemic scleroderma have more antibodies in the blood that are linked to severe complications and an increased likelihood of death. They say this finding, published today in Arthritis & Rheumatism, suggests physicians can use these disease markers to screen and treat scleroderma patients proactively.

Sildenafil may improve cardiac function in children, young adults with single ventricle defects

Sildenafil, also known as the erectile dysfunction drug Viagra, may give a boost to underdeveloped hearts in children and young adults with congenital heart defects. Researchers from The Children's Hospital of Philadelphia report that sildenafil significantly improved echocardiographic measures of heart function in children and young adult survivors of single ventricle heart disease palliation.

Cellular-level images of the living eye

The same technology used by astronomers to obtain clear views of distant stars is now being used by optometrists to perform incredibly detailed examinations of the living eye.

Breast brachytherapy with strut-based applicator effective for women with DCIS

Breast brachytherapy with a strut-based applicator appears to be an effective treatment for women who have ductal carcinoma in situ (DCIS) of the breast, according to a groundbreaking study presented at the annual meeting of the American Society of Breast Surgeons, held in Phoenix May 2-4.

Researchers discover how diabetes affects specific brain area leading to memory loss

Badly controlled diabetes are known to affect the brain causing memory and learning problems and even an increased incidence of dementia, although how this occurs is not clear.

Oral nutriceutical restores vision to otherwise hopeless patients facing permanent loss

There may be new found hope for patients whose vision is threatened when medicine injected directly into the eyes fails to cause abnormal blood vessels to recede. While injectable drugs called angiogenesis (an-gee-oh-jen-esis) inhibitors are considered a modern miracle and have become the standard of care for patients with the fast-progressive form of macular degeneration, they are not foolproof.

Researchers identify new mechanism that causes choroidal neovascularization

Sloppy shipping of a donated human retina to an Indiana University researcher studying a leading cause of vision loss has inadvertently helped uncover a previously undetected mechanism causing the disease. The discovery has led researchers to urge review of how millions of dollars are spent investigating the cause of a type of age-related macular degeneration called choroidal neovascularization.

PDE4 enzyme regulates division of tumour cells and blood vessel growth in cancer tissue

Lung cancer is the leading cause of cancer death throughout the world. Standard treatment methods do not usually result in long-term recovery. In addition to the proliferation of the tumour cells, the growth of blood vessels controls tumors development. The blood vessel growth is controlled by several signalling molecules. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim and Justus Liebig University Giessen have discovered a molecule that plays a key role in this process. They succeeded in reducing tumour growth in their experiments by blocking the phosphodiesterase PDE4.

LRI applauds ACR colleagues for new lupus nephritis guidelines

The Lupus Research Institute (LRI) applauds our colleagues at the American College of Rheumatology (ACR) for issuing new guidelines to help healthcare professionals screen, diagnose and treat lupus nephritis, a type of kidney disease associated with lupus. Available on the ACR website, the new guidelines are just published in the April 2012 issue of Arthritis Care & Research.

Hypoxia may be a primary cause of uncontrollable tumor growth in cancers

Low oxygen levels in cells may be a primary cause of uncontrollable tumor growth in some cancers, according to a new University of Georgia study. The authors' findings run counter to widely accepted beliefs that genetic mutations are responsible for cancer growth.

Scientists identify first gene associated with congenital asplenia

Researchers at Weill Cornell Medical College and Rockefeller University have identified the first gene to be linked to a rare condition in which babies are born without a spleen, putting those children at risk of dying from infections they cannot defend themselves against. The gene, Nkx2.5, was shown to regulate genesis of the spleen during early development in mice.

Large-scale, patient-specific simulations of blood function

Having a virtual copy of a patient's blood in a computer would be a boon to researchers and doctors. They could examine a simulated heart attack caused by blood clotting in a diseased coronary artery and see if a drug like aspirin would be effective in reducing the size of such a clot.

Study investigates use of stem cells to treat lower-limb peripheral artery disease

Research led by vascular surgeons at Dartmouth-Hitchcock may offer new hope to sufferers of peripheral artery disease, the cause of nearly 60,000 lower-limb amputations annually, through the use of a patient's own stem cells.
