A group of scientists at The Scripps Research Institute (TSRI) and San Diego Supercomputer Center at the University of California at San Diego (UCSD) have used a powerful laser in combination with innovative quantum mechanical computations to measure the flexibility of mouse antibodies.

The new technique, described in an upcoming issue of the journal Proceedings of the National Academy of Sciences, is significant because protein flexibility is believed to play an important role in antibody-a

Surgeons at Rush-Presbyterian-St. Luke’s Medical Center in Chicago have documented the first use of a blood vessel from the abdomen to treat a blocked artery in the brain. The case study was published in the December issue of Surgical Laparoscopy, Endoscopy and Percutaneous Techniques.

Researchers at the Johns Hopkins Children’s Center report that two doses of the varicella vaccine for chicken pox given one to two months apart can be safe and effective in children with chronic kidney disease.

The findings, reported in the January issue of Pediatric Nephrology, are critical for chronic kidney disease patients, particularly children who will eventually undergo a kidney transplant. After transplantation, immunosuppressive medications put these children at high risk for

Faint glow given off only when cells are killed could speed drug development for cancer, stroke, other diseases

The process that makes fireflies glow bright in the summer night can also shed light on how well new medicines work, showing immediately whether the drugs are effective at killing cells or causing other effects.

That’s the conclusion of a team of scientists from the University of Michigan Health System, who report that they have inserted the gene for a firefly
