... "Dystrophin prevents the cell membrane from being torn by the shear forces produced during muscle contraction," says first author Swarnali Acharyya, a pre-doctoral student in Guttridge's laboratory. The researchers found that dystrophin levels were reduced in the muscles of mice with cancer cachexia, an...UCSD project takes fish collection into the digital age
... medical technology used to image brain tumors and torn knee ligaments is now taking the field of marine biology to a new dimension by allowing anyone with Internet access to examine fish as never before.

... ACLs are currently reconstructed by replacing the torn ligament with a tendon graft. This painful operati.... The gel provided a physical "bridge" between the torn ligament ends, while the platelets churned out a variety of growth factors. Compared with untreated ...Using stem cells to repair torn tendons
...es with these cells and implanted the sponges into torn Achilles tendons of rats, they found that the cells not only survived the implantation process, but were also able to invade the injury and repair the tendon for at least 7 weeks after implantation. The cells changed their appearance to look more lik...One-dimensional diffusion accelerates molecular motors
...are tiny protein polymers that can be built up and torn down like scaffolding. They also make up "tracks", along which motor proteins pull the halves of chromosomes into existing daughter cells. Until now, scientists have not known how the length of microtubule gets regulated, nor how the proteins reach t...Bones in motion: Brown scientists to create new 3-D X-ray system
...geon trying to figure out the best way to repair a torn knee ligament or an evolutionary biologist tracing the disappearance of digits in pigs would face a difficult task. To see the exact position and movement of bones and the ligaments, tendons and cartilage that surround them, would require cutting int...... the crust never there? Was it once there but then torn away on huge geological faults? If so, then how and why?" To answer some of these questions Dr MacLeod with a team of scientists, led by marine geophysicist Professor Roger Searle, Durham University, will travel to the area which lies mid-way betwe...JCI Table of Contents -- July 2, 2007

A torn anterior cruciate ligament (ACL) is among an athlete's most-dreaded injuries, often requiring surgery and months of rehab, as has been the case with Philadelphia Eagles quarterback Donovan McNabb. While being tackled in football or hurtling into an...Study points to new way to predict death risk from torn aorta
