Procedures-In
a crossover design, SAP was measured via Doppler ultrasonography when dogs were sitting (on hind limbs with nonmeasured forelimb bearing weight) and laterally recumbent, with the cuff position at the level of the right atrium for both positions. Seven measurements were obtained per position for each dog.
Results-Mean +/- SD SAP was significantly higher in the sitting (172.1 +/- 33.3 mm Hg) versus recumbent (147.0 +/- 24.6 mm Hg) position, and this difference was evident for 44 of 51(86%) dogs. The mean difference in measured SAP between the 2 positions was 25.1 +/- 28.5 mm Hg. Blood pressure Selleckchem BAY 1895344 measurements had a significantly higher repeatability in the recumbent position than in the sitting position.
Conclusions and Clinical Relevance-Blood pressure measurements in dogs
were significantly affected by body position, and they were higher for most dogs when sitting rather than laterally recumbent. Blood pressure measurements in the laterally recumbent body position were less variable than in the sitting position. (J Am Vet Med Assoc 2013;242:1523-1527)”
“A new approach is presented to quantify the so-called “”heat affected zone”" (HAZ) during femtosecond laser pulse processing. Ablation of titanium nitride (TiN) thin films (similar to 3 mu m thickness) by multiple femtosecond laser pulses (tau = 130 fs, lambda = 800 nm) in air environment was studied by means of two different surface analytical methods selleck screening library both being sensitive to chemical alterations check details at the surface. Scanning Auger electron microscopy was applied for a visualization of the spatial distribution of specific elements (Ti, O) within the laser-modified areas. The chemical state of the irradiated surface was revealed by complementary x-ray photoelectron spectroscopy. Both methods were used for a depth-profiling chemical analysis (tracking the elements Ti, N, O, and C) using an Ar-ion beam for surface sputtering. In a
narrow laser fluence range slightly below the ablation threshold of TiN significant superficial oxidation can be observed leading to the formation of substoichiometric TiO(2-x). At fluences above the ablation threshold, an increased titanium concentration is observed within the entire ablation craters. Following upon sputter removal the elemental distribution into the depth of the nonablated material, the results allow an estimation of the heat-affected zone for femtosecond laser ablation in air environment. According to our analyses, the HAZ extends up to a few hundreds of nanometers into the nonablated material. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3311552]“
