Mechanical forces drive early heart development

...scientists better understant the roles physics and mechanics play in the developing heart and in heart defects. The heart either loops or it doesn’t, and if it loops it either goes left or right,’ and those often are the only distinctions made. It takes 21 days to hatch a chicken; at day 1 tubes form on two s...

Researchers Aim To Develop Next Generation Of Surgical Robots

...t are reversed. But a robot can understand all the mechanics and compensate for them, eliminating the fulcrum effect," Peine said. These robots can also perform movements or surgeries that call for fine dexterity. In prostate cancer surgeries some nerves are inadvertently damaged causing incontinence and impot...

Nanotechnology at its best: Nanomotors And Mechanical Nanoswitches

...ork on bionanotechnology exploring single molecule mechanics and nanomotors for technical applications. Engineering principles of biological nanosystems for the development of new technologies has been devised and deciphered by Dr. Vogel. In addition the use of biological motors to build assembly lines for ...

...ant we use, a highly successful implant with great mechanics and 10 years of clinical success. Only the shape of this new implant is different, to make it feel more natural.’ The clearance allows Zimmer to begin distributing the implant to U.S. orthopedic surgeons and hospitals as part of Zimmer’s NexGen Com...

Discovery of Agile Molecular Motors Could Aid in Treating Motor Neuron Diseases

...dynactin motor, while Yale’s group delves into the mechanics of the motor itself,” says Holzbaur. “We’re deconstructing the system to understand how it all works in a living cell. In the lab, we start with a clean microtubule with a motor walking across it, but in the cell it’s different: microtubules are pack...

Cell Behavior Better Understood with Nano Probe

...oblem came from a trick related to the basic fluid mechanics of ionic fluids, as the researchers exploited strong capillary forces to confine fluid within a nanoscale domain of the probe inlet (enabling natural separation of liquid and gaseous environments) and then used the classical Taylor electrohydrodynami...

Too Much of Air in the Lungs Results in VILI

...inflation can safely improve gas exchange and lung mechanics and may confer protection from biotrauma,’ the authors wrote. ‘Differences between LVDI and HV suggest that an optimal frequency range of deep inflation exists, within which the benefits of maintaining an open lung outweigh injury incurred from over-...

Study Unveils West Nile Virus Immune Evasion, Points to Vaccine Development

...aling. The remaining key is figuring out the exact mechanics of how the strains block signaling, a project Dr. Gale’s team is already at work on. Fortunately, North American strains are extremely similar – in fact, the one that appeared in the United States in 1999 and the Texas strain used in this study are...

Foot Deformity Could Be Corrected With Minimal Surgery

... Ponseti, we do have a better understanding of the mechanics of the foot and ankle which has made it possible to figure out how best to gradually correct the deformity in CVT." The treatment is based on principles developed in the 1950s for clubfoot, another congenital foot deformity. Ignacio Ponseti, M.D., ...

"The work is particularly encouraging for the use of brain stimulation in chronic disease such as stroke and dementia. "The challenge now is to find ways of combining stimulation with drug therapies." Professor Clive Ba...
