Cell structures exhibit novel behaviors, mimic red blood cells and liquid crystals

Researchers at the University of Pennsylvania and Yale University have manipulated the internal, structural components of cells, creating a set of simulated cellular structures with novel mechanical properties, including one that acts like a red blood cell and another that mimics the soft, elastic behavior commonly found in novel synthetic materials called liquid crystal elastomers.

Raman spectroscopy for faster body-fluid tests

University of Rochester researchers announce in the current issue of Applied Optics a technique that in 60 seconds or less measures multiple chemicals in body fluids, using a laser, white light, and a reflective tube.

New way of making artificial lungs more efficient

Artificial lungs are cumbersome beasts, but they can be a lifesaver for people with serious respiratory diseases or lung damage. Sitting outside the body, they take over the task of soaking up excess carbon dioxide from the blood and infusing it with oxygen.

New target for removing unwanted ammonia from the body

Thousands of people with liver and kidney disease die every year from too much ammonia in their blood, and scientists from the United States and Japan have found a possible solution.

FDA approves Soliris (eculizumab), first treatment for paroxysmal nocturnal hemoglobinuria

The U.S. Food and Drug Administration (FDA) has approved Soliris (eculizumab), the first product for the treatment of paroxysmal nocturnal hemoglobinuria (PNH), a rare type of blood disorder that can lead to disability and premature death.

FDA strengthens safety information for Erythropoiesis-Stimulating Agents (ESAs)

The U.S. Food and Drug Administration (FDA) has issued a public health advisory outlining new safety information, including revised product labeling about erythropoiesis-stimulating agents (ESAs), widely-used drugs for the treatment of anemia.

Mechanism driving iron overload in thalassemia identified

Led by researchers at Weill Cornell Medical College in New York City, an international group of scientists has pinpointed a specific genetic relationship as the cause of dangerous iron overload in persons with a form of the inherited blood disease, beta-thalassemia.

Researchers discover how to fight iron disorders with a drug against hypertension

We all know that iron deficiencies are dangerous, but also too much iron is bad for our health. Our body stores excess iron in various tissues, where it can lead to organ failure and even death if not treated before irreversible damage has occurred.

Folate and vitamin B12 preserve cognitive function among seniors

Folate and vitamin B12, two important nutrients for the development of healthy nerves and blood cells, may work together to protect cognitive function among seniors, reports a new epidemiological study from the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (USDA HNRCA).

Stroke risk for sickle cell children with early complications

Children with sickle cell disease who experienced major complications such as pain and lung disease early in life are at no greater risk for stroke or death during later childhood, new research from UT Southwestern Medical Center shows.

Virtual human metabolic network for medical science

Bioengineering researchers at UC San Diego have painstakingly assembled a virtual human metabolic network that will give researchers a new way to hunt for better treatments for hundreds of human metabolic disorders, from diabetes to high levels of cholesterol in the blood.

Gene produces springy protein keeping nerve cells flexible

If you bend a knee or an elbow, the nerves in your limbs stretch but do not break. A University of Utah study suggests why: A gene produces a springy protein that keeps nerve cells flexible. When the gene was disabled in tiny nematode worms, their nerve cells literally broke.

Blood levels of vitamin folate in women of childbearing age decreasing

From 1999 through 2004 there was an 8% to 16% decline in the level of the vitamin folate in the blood of U.S. women of childbearing age, according to a study published in the Jan. 5 issue of CDC's Morbidity and Mortality Weekly Report, the AP/Houston Chronicle reports (Stobbe, AP/Houston Chronicle, 1/4).

FDA expands use of Herceptin

The U.S. Food and Drug Administration (FDA) has expanded the approved use of Herceptin, a biological cancer drug. The new indication is for Herceptin, in combination with other cancer drugs, for the treatment of HER2 positive breast cancer after surgery (lumpectomy or mastectomy).
