Conclusions and Clinical Relevance-Complete ductal occlusion resulted in immediate removal of the volume overload state and eventual
return of cardiac chamber dimensions to reference range, suggesting Selleckchem Caspase inhibitor regression of eccentric hypertrophy. Systolic dysfunction persisted in some dogs but appeared to be clinically unimportant. Most cardiovascular changes were independent of patient age at the time of the procedure.”
“Thermodynamic stability of hydrogenated polar InP(111)B surfaces is systematically studied by performing first-principles density functional calculations. Employing a thermodynamic approach, the hydrogen chemical potential is considered as functions of temperature and pressure. The calculated Gibbs free energies demonstrate that the surface structures of InP(111)B strongly depend on growth condition and surface compositions. The (2 x 2) surfaces with 3PH(2)+PH(3), 3H+PH(3), 3H, and P trimer, and the (root 3 x root 3) surface with In adatom are stable phases under different chemical potentials of P and H, respectively. Moreover, our calculations suggest that the ideal surface and most of (root 3 x root 3) surfaces are just metastable due to their deviation from
electron counting rule. The calculated surface phase diagrams as the functions of temperature and pressure of H(2) reveal that the (2 x 2) surface with P trimer is stable under the experimental growth condition (550-800K). Once the samples are cooled down in a H-rich ambient, the hydrogenated InP(111)B surfaces are more favorable. (C) 2010 American Institute of Physics. [doi:10.1063/1.3331767].”
“Background: Transmembrane Transporters inhibitor Law enforcement officers use electronic control devices (ECDs), such as the TASER X26 (TASER International, Inc., Scottsdale, AZ, USA),
to control resisting subjects. Some of the debate on the safety of the devices has centered on the electrical characteristics of the devices. The electrical characteristics published by TASER International have selleck products historically based on discharges into a 400 Omega resistor. There are no studies that the authors are aware of that report the electrical characteristics under a physiologic load. In this study, we make an initial attempt to determine the electrical characteristics of the TASER X26 during a 5-second exposure in human volunteers.
Methods: Subjects received an exposure to the dry, bare chest (top probe), and abdomen (bottom probe) with a standard TASER X26 in the probe deployment mode for 5 seconds. There were 10-11 pulse captures during the 5 seconds. Resistance was calculated using the sum of the absolute values of the instantaneous voltage measurements divided by the sum of the absolute values of the instantaneous current measurements (Ohm’s Law).
Results: For the eight subjects, the mean spread between top and bottom probes was 12.1 inches (30.7 cm). The mean resistance was 602.3 Omega, with a range of 470.5-691.4 Omega.
