Health Research: Oral hepatitis B vaccine could become a reality ♦ New way to evaluate meniscus tears ♦ Sensor can report conditions from deep in the body

New way to evaluate meniscus tears An individual’s meniscus (cushion in the knee providing stability, load bearing and preservation of the knee joint. It is also one of the most easily injured and difficult to heal. Researchers utilized MRI data to determine the potential for biologic healing following a meniscus tear.
Sensor can report conditions from deep in the body Scientists have devised and demonstrated a new, shape-shifting probe, about 100th as wide as a human hair, which is capable of sensitive, high-resolution remote biological sensing that is not possible with current technology. The design could have a major impact on research in medicine, chemistry, biology and engineering.
New genetic link found for alcohol-related liver cirrhosis In most people, any liver damage that might occur from drinking alcohol is reversible. However, in 25 to 30 percent of alcoholics what begins as accumulation of fat in the liver progresses to inflammation, fibrosis and ultimately irreversible cirrhosis, for which the only treatment is a liver transplant..
New compounds could offer therapy for multitude of diseases An international team has demonstrated that the compounds they developed can safely prevent harmful protein aggregation in preliminary tests using animals. The findings raise hope that a new class of drugs may be on the horizon for the over 30 diseases that involve protein aggregation, including diabetes, cancer, spinal cord injury, Alzheimer’s disease, Parkinson’s disease and amyotrophic lateral sclerosis
Oral hepatitis B vaccine could become a reality In a new study, researchers report progress toward perfecting a radical new method of producing vaccines using genetically modified corn. The approach could lead to an oral hepatitis B vaccine that requires no refrigeration and costs less than $1 per dose to manufacture.
