University Of Florida Researchers Hope To Ease Asthma Pains And Provide A Sigh Of Relief
...late the structure of thedrug so as to control the motions of the receptor, we can change the shapeof the drug/receptor complex." Richards said this change in the drug/receptor complex may provide amethod for lengthening the time it takes for the drug to leave thereceptor, providing a longer action ti...Robotics go where no surgeon has gone before
...operating directly on the patient. The surgeon's motions are relayed to a computer which digitizes them. The computer uses this information to direct two robotic arms, which are attached to the operating room table. These arms hold the instrument tips that replicate the precise maneuvers of the surgeon. ...Getting older and feeling weaker?
...that simulates and measures the effects of various motions and stresses on the spine and supporting muscles. "The assumption is that reducing fatigue will reduce injury as well as increasing efficiency," he remarks. "Industry is very receptive to this type of research." ...Landmark study uncovers reasons behind recurring back injury
...s harm. Those are the kinds of motions an injured person should never do at all," Marras said. "Bottom line -- you can send people back to work after a back injury, but you have to be very careful about what you have them do." ...'Virtual stomach' reveals pill's path
... the stomach walls. He found that these wave-like motions underlie both the shear stresses that contribute to the breakdown of the tablet and the mixing of the medicine.Pal also found that extended periods of moderate shear stress exist which continuously wear the tablet's surface and lead to gradual disper...Surgeons perform nation's first Zeus robotics system-assisted gastric bypass surgery
...nefits are that Zeus can repeat the surgeon's hand motions with great precision and without fatigue or tremor. It is important to note that the equipment does not replace humans but, instead, enhances certain human functions that are improved by the use of robotics. This allows trained staff to better utiliz...Engineering researchers are designing the ultimate fabrics, for casual or military wear
...d. "They can be designed to be aware of the user's motions and of his surroundings." For example, sensors called accelerometers -- which are used to cue airbags to deploy -- can detect changes in speed and direction. There are visual sensors that can project images to tiny displays clipped to eye glasses.

They then learn to match similar items, and then categories.

"One of the important features we found is that not all symptoms of Parkinson's Disease respond equally to treatment," notes Lang.

...hat our analytical model can predict the patients' motions quite well," said Nicolelis. "We only had five minutes of data on each patient, during which it took a minute or two to train them to the task. This suggests that as clinical testing progresses, and we use electrode arrays that are implanted for a lo...3D neutron-based medical imaging, 4D lung scans, and hitting a moving tumor

A 4D scan provides a precise, stable location of a tumor--since the data from the "fourth dimension" can correct for image blurring and other distortions caused by a patient's breathing and general movements. 4D imag...Angioplasty, robotically assisted keyhole bypass combo appears effective
