First direct mechanical communication of mitochondria, cardiomyocyte nucleus shown

In a paper being presented in two American Physiological Society sessions at Experimental Biology 2006, a joint Estonian-French team demonstrated "for the first time that mitochondria are able to induce nuclear deformation, suggesting that mitochondria may mechanically regulate nuclear function." The team, which has been collaborating for over 10 years, reported that it recently "found a v...

Mechanical 'artificial hearts' can remove need for heart transplant by returning heart to normal

Mechanical 'artificial hearts' can be used to return severely failing hearts to their normal function, potentially removing the need for heart transplantation, according to new research. The mechanical devices, known as Left Ventricular Assist Devices (LVADs), are currently used in patients with very severe heart failure whilst they await transplantation. The new study, published in the Ne...

Mechanical Heart

The world's first self-contained mechanical heart has been implanted and the patient is resting comfortably after the seven hour operation, a US hospital has announced. The revolutionary procedure is the first major advance in the development of an artificial replacement heart in nearly two decades. If successful, the device could help thousands of patients who die each year waiting for...

Mechanical forces drive early heart development

A biomedical engineer sees the heart as a pump, plain and simple, a machine shaped by genetics and complex biomechanical forces.Larry A. Taber, professor of biomedical engineering at Washington University in St. Louis, has been probing the forces, stresses and deformations of the heart since the mid-1980s. A major focus of his work is to show that biomechanical forces may be as important as genet...

Nanotechnology at its best: Nanomotors And Mechanical Nanoswitches

Physics has been coupled and nanotechnology is spreading its wings to medicine and pharmaceuticals.// Julius Springer Prize for Applied Physics for 2006 will be awarded to Dr. Viola Vogel for her creative and pioneering work on bionanotechnology exploring single molecule mechanics and nanomotors for technical applications. Engineering principles of biological nanosystems f...

Computer-Driven System Reduces Patient Mechanical Ventilation Time Significantly

For patients with acute respiratory failure, a computer-driven system can significantly reduce the duration of mechanical ventilation and length of stay in the intensive// care unit (ICU), as compared with the traditional physician-controlled weaning process. The study, which was conducted in five medical-surgical ICUs in Barcelona, Brussels, Créteil, Geneva and Paris, appears in the...

Patients With Alcohol Problem Need Mechanical Ventilation

New findings indicate that medical patients with an alcohol-use disorder (AUD) are more likely to require mechanical ventilation, and need it for a longer period of time. More than 300,000 patients receive mechanical ventilation during intensive care per year in the United States, even though the hospital mortality rate for ventilated patients can approach 50 percent. Mechanical v...
