New Drug Capsule May Allow Weekly HIV Treatment

The new capsule is designed so that patients can take it just once a week, and the drug will release gradually throughout the week. This type of delivery system could not only improve patients' adherence to their treatment schedule but also be used by people at risk of HIV exposure

Dopamine Levels Fall During Migraine Attacks, Brain Scans Show

This could help scientists better understand dopamine-based therapies for migraines as well as a patient's behavior during an attack. The connection between dopamine and migraines has long been a poorly understood therapeutic and research area, says Alex DaSilva, assistant professor at the U-M School of Dentistry and Center for Human Growth

No Evidence that Gadolinium Causes Neurologic Harm

Gadolinium-based contrast media were introduced in 1988 as a means of enhancing MRI images and are commonly used today. The contrast agent is injected into the patient's bloodstream and eliminated from the body through the kidneys. "It's estimated that approximately 400 million doses of gadolinium have been administered since 1988," said

Prototype UT Equipment can Detect Rheumatoid Arthritis

Several years ago, researchers from the University of Twente joined forces with a number of companies to develop a prototype for a machine that would combine ultrasound and photoacoustics medical imaging techniques. Combining these techniques allows specialists to create images of superficial areas of the body that can offer doctors

Squirtable Elastic Surgical Glue Seals Wounds in 60 Seconds

Biomedical engineers from the University of Sydney and the United States collaborated on the development of the potentially life-saving surgical glue, called MeTro. MeTro's high elasticity makes it ideal for sealing wounds in body tissues that continually expand and relax -- such as lungs, hearts and arteries -- that are otherwise

Asymmetric Sound Absorption Lets in the Light

Many asymmetric absorbers, those that only absorb sound coming in from one direction, are currently based on a single-port system, where sound enters one side and is absorbed before a rigid wall. In this design, however, light and air are unable to pass through the system. But a combined research
