This paper comprises an experimental and theoretical study on gas bubble formation in a liquid in a spinning disc device.
Currently, artificial spinal discs require transection or partial removal of the annulus fibrosis in order to excise the nucleus and implant a prosthetic nucleus or implant a total disc device, respectively.
However, under external forces applied by an atomic force microscope or by a spinning disc device causing shear forces, the mutant caused stronger cell adhesion than the wild-type integrin.
The combination of the small high-speed disc device and the laboratory centrifuge is particularly advantageous when dealing with biological products at the early stages of process development for which only small quantities of test material are often available.
All hospitals participating in the study used the same artificial lumbar disc device.
All MR-HIFU treatments were successfully completed using the investigational DISC device; no technical failure was observed.
USD feed zone studies were conducted with a rotating disc device (RDD) depicted in Figure 1A (Boychyn et al., 2001).
A schematic illustration of the clinical volumetric MR-HIFU system with and without the presence of the investigational DISC device is shown in Figure 1.
All patients gave written informed consent for conducting an MR-HIFU procedure with the presence of the direct skin cooling (DISC) device.
On the basis of the small number of patients studied, using the additional DISC device in this trial appears to be safe.
In this study, patients were asked to lie down in prone position (feet first) on the patient MR table top with the integrated DISC device.
