Supercomputer used to determine structures and functions of proteins

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory are proposing to use a supercomputer originally developed to simulate elementary particles in high-energy physics to help determine the structures and functions of proteins, including, for example, the 30,000 or so proteins encoded by the human genome. Structural information will help scientists better understand proteins’ role in disease and health, and may lead to new diagnostic and therapeutic agents.

Children with sickle cell disease are living longer, dying less often from their disease

Children with sickle cell disease, an inherited red blood-cell disorder, are living longer, dying less often from their disease and contracting fewer fatal infections than ever before, researchers at UT Southwestern Medical Center at Dallas report. Their study, which will appear in the June edition of the scientific journal Blood, is the first to evaluate survival rates of children receiving the most modern treatments for sickle cell disease. It's also one of the largest published sickle cell studies to date. Researchers followed more than 700 Dallas-area children with the disease over two decades.

Stenting for Stroke Prevention is More Effective Than Surgery in Keeping Blood Vessels Open

Research presented in a six-hour symposium on carotid artery disease at the 29th Annual Scientific Meeting of the Society of Interventional Radiology showed carotid artery stenting to be safe and effective for highrisk patients. Currently, the standard of care for stroke prevention in patients with moderate to severely blocked carotid arteries is carotid endarterectomy surgery. The ARCHeR trials treated patients who were high-risk surgical candidates with carotid artery stenting with and without embolic protection, a device to capture debris that may break off during the procedure.

Alfuzosin, new treatment for Acute Urinary Retention

The results of the ALFAUR (ALFuzosin in Acute Urinary Retention) study, announced today at the XIXth European Association of Urology (EAU) Congress in Vienna, Austria, indicate that the uroselective alpha1-blocker alfuzosin 10 mg once daily (OD) may have a beneficial effect in the management of male patients suffering from acute urinary retention (AUR), a sudden inability to pass urine that results in a painful distension of the bladder, requires immediate management with urethral catheterization and could necessitate surgical intervention.

Discovery of new gene sheds light on human brain development

With the identification of the gene responsible for a newly recognized type of mental retardation, researchers at Beth Israel Deaconess Medical Center (BIDMC) have also discovered what appears to be the key target in the evolution of the frontal lobes of the brain's cerebral cortex. The findings offer a key insight into the complex puzzle of human brain development - and the evolution of human behavior.

A debate over the origins of what is sometimes called "junk" DNA has been settled

A debate over the origins of what is sometimes called "junk" DNA has been settled by research involving scientists at the Center for Advanced Research in Biotechnology (CARB) and a collaborator, who developed rigorous proof that these mysterious sections were added to DNA "late" in the evolution of life on earth, after the formation of modern-sized genes, which contain instructions for making proteins.

Asthma study turns up new information on viral infections

Researchers know that viral infections can exacerbate asthma and, in turn, make people with the condition more sensitive to environmental exposures such as endotoxin. But how viral infections contribute to this sensitivity in airway cells has not been clear. A recent study led by investigators from the University of Iowa Roy J. and Lucille A. Carver College of Medicine and the Veterans Affairs Medical Center (VAMC) in Iowa City shows, for the first time, that viral infections may increase environmental sensitivity in lung epithelial (surface) cells by changing expression of receptors on those cells.

Scientists have taken a significant leap forward in understanding the complex ways that molecules work together in cells.

Although scientists already know a lot about single molecules, they know very little about how they are assembled into larger molecular complexes or "machines" and how these machines work together to create a complete, functioning cell. The problem is like trying to assemble a puzzle with billions of pieces– with only the shapes of some pieces to go on.

Brain signals could act as remote controls

In their first human studies of the feasibility of using brain signals to operate external devices, researchers at Duke University Medical Center report that arrays of electrodes can provide useable signals for controlling such devices. The research team is now working to develop prototype devices that may enable paralyzed people to operate "neuroprosthetic" and other external devices using only their brain signals.
