New medical devices can cause new immune problems

Medical devices are traditionally thought of as fairly simple implants such as stents and hip replacements – pieces of plastic or metal that are placed in the body to handle a very specific function. But biomedical devices now on the drawing board are considerably more sophisticated and represent an unprecedented melding of man and machine.

Better ways to heal and regenerate bones using microcomputed tomography imaging

Tissue engineers can choose from a wide range of living cells, biomaterials and proteins to repair a bone defect. But finding the optimum combination requires improved methods for tracking the healing process.

Nanoscale mechanism to externally control the function and action of a protein

"We can switch a protein on and off, and while we have controlled a specific protein, we believe our approach will work with virtually any protein," said Giovanni Zocchi, assistant professor of physics at UCLA, member of the California NanoSystems Institute and leader of the research effort. "This research has the potential to start a new approach to protein engineering."

Defect in one of nature's oldest proteins may be an underlying cause in human miscarriages

University of Rochester scientists studying a vital protein called Serum Response Factor (SRF) in mice have learned new and unexpected facts about SRF's role in early cardiovascular development, and how a defect in this gene may be an underlying cause in human miscarriages.

Scientist develops way to deliver promising genetic tool into living cells

By exploiting an HIV protein that readily traverses cell membranes, Carnegie Mellon University scientists have developed a new way to introduce a gene-like molecule called a peptide nucleic acid (PNA) directly into live mammalian cells, including human embryonic stem (ES) cells.

Rifampicin can prevent the formation of protein fibrils associated with Parkinson's disease

Researchers at the University of California, Santa Cruz, have shown that rifampicin, an antibiotic used to treat leprosy and tuberculosis, can prevent the formation of protein fibrils associated with the death of brain cells in people with Parkinson's disease. The drug also dissolved existing fibrils in laboratory tests.
