In the same group of subjects, imaging and measurements were repeated using BK Medical Flex Focus 400 ultrasound system

with linear (18 MHz) and curved 5 (MHz) transducers. The MobiUS system was also used to image plastic cylinders and procedure needles embedded in tofu bars. Outside diameters of cylinders were measured using digital calipers and sonography.\n\nResults: The mean diameter of the hyomental muscle in 10 healthy volunteers was 7.22 +/- 1.6 mm using BK 18 MHzprobe, 7.11 +/- 1.7mmusing MobiUS 7.5 MHz probe, and 7.84 +/- 2 mm using MobiUS 3.5 MHz probe. These means were not statistically different (BK vs Mo 7.5, P = .74, and BK vs Mo 3.5, P = .13). The mean outside diameter of plastic cylinders Smoothened Agonist measured with digital calipers was 10.1 +/- 0.2 mm (n = 5) vs 9.8 +/- 0.3 mm and 10.2 +/- 0.2 mm using 3.5 and 7.5 MHz probes, respectively. These means were not statistically different (calipers vs Mo

3.5, P = .16 and calipers vs Mo 7.5, P = .39).\n\nConclusion: Mobisante MobiUS system was able to acquire clinically useful images of the suprahyoid airway and muscular architecture in the mouth floor and allowed accurate measurements ACY-738 datasheet of linear distances.

“An effective method for mass production of field-emission microcathodes (mu FECs) is suggested and described. The main properties of the mu FECs are calculated using the actual geometric parameters of the system (emitting nanotip radius similar to 15-20 nm, interelectrode distance similar to 1.5-2 mu m, etc.). It is shown that the electric field strength in the immediate vicinity of a nanotip is several units of 10(7) V/cm at comparatively low (100-200 V) voltages applied. A series of probable applications taking advantage of the unique features of the mu FECs Bcl-2 inhibitor are suggested. (C) 2010 Elsevier B.V. All rights reserved.”
“To address the pressing need for better in vitro testicular toxicity models, a workshop sponsored by the International Life Sciences Institute (ILSI), the Health and Environmental

Science Institute (HESI), and the Johns Hopkins Center for Alternatives to Animal Testing (CAAT), was held at the Mt. Washington Conference Center in Baltimore, MD, USA on October 26-27, 2011. At this workshop, experts in testis physiology, toxicology, and tissue engineering discussed approaches for creating improved in vitro environments that would be more conducive to maintaining spermatogenesis and steroidogenesis and could provide more predictive models for testicular toxicity testing. This workshop report is intended to provide scientists with a broad overview of relevant testicular toxicity literature and to suggest opportunities where bioengineering principles and techniques could be used to build improved in vitro testicular models for safety evaluation. Tissue engineering techniques could, conceivably, be immediately implemented to improve existing models.
