Antibody/enzyme combo protects transplanted lungs from oxidative stress damage

Researchers based at the University of Pennsylvania School of Medicine have combined the precision of antibodies with the power of an antioxidant enzyme to create a new way to protect transplanted lungs from oxidative stress – also known as free radical damage – before and during transplantation.

Their findings, presented in the April edition of Nature Biotechnology and available online now, demon

Discovery could lead to new therapies for Smith-Magenis Syndrome

Researchers at Michigan State University have identified the gene responsible for a developmental disorder known as Smith-Magenis syndrome (SMS), a discovery that could lead to new therapies for the disorder and the myriad problems that accompany it.
The finding is documented in the March 24 issue of Nature Genetics, a prestigious peer-reviewed British journal.

SMS is a chromosome microdeletion syndrome th

Using direct-write assembly of organic ink, researchers at the University of Illinois at Urbana-Champaign have developed a technique for fabricating three-dimensional microvascular networks. These tiny networks could function as compact fluidic factories in miniature sensors, chemical reactors, or computers used in applications from biomedicine to information technology.

“The fabrication technique produces a pervasive network of interconnected cylindrical channels, which can range from 10 t

Aim is better filters for contaminants

Tracy L. Cail, a Ph.D. student in geological sciences at Virginia Tech, is developing a new method for calculating sticking efficiency at the nanoscale with the aim of someday developing improved filters for removing contaminants from solutions, such as bacteria from groundwater. She will present her research at the 225th American Chemical Society national meeting March 23-27 in New Orleans.

In the past, scientists have used theoretical

Because methanol, as a liquid, would be easier to dispense using current infrastructure, it will likely be one of the first fuels for fuel cells.

Speaking at the 225th national meeting of the American Chemical Society March 23-27 in New Orleans, Yu Seung Kim, a former research scientist at Virginia Tech, will report the results of studies at Virginia Tech to determine the optimum materials for use as a proton exchange membrane in a methanol-based fuel cell.

Methanol is the

In the future, consumers may be adding a powerful “spice” to their food that could save lives. Researchers in Canada are developing a natural antibody cocktail that can help prevent the most common foodborne germs, including E. coli and Salmonella, which cause thousands to become sick or die each year in this country.

Derived from freeze-dried egg yolk, the substance is nicknamed a spice because it can be sprinkled or sprayed onto meats, fruits and vegetables to complement existing sanitati
