Similarly, it was shown that a linear dispersion relation is obtained in the presence of the SiC substrate, and also for various distances between adjacent carbon layers for AA stacking. (C) 2011 American Institute of Physics. [doi:10.1063/1.3585829]“
“Objective. The aim of this study was to clarify the
sonographic features of the masseter muscle as indices for judging the efficacy 4-Hydroxytamoxifen inhibitor of massage treatment.
Study design. Fifteen patients with temporomandibular disorder (10 with unilateral and 5 with bilateral muscle pain) underwent massage treatment alternately on the bilateral masseter and temporal muscles with an oral rehabilitation robot. Sonography was performed before and after treatment, and the masseter thickness and existence of anechoic areas were evaluated.
Results. The thickness on the symptomatic side
in the unilateral group significantly decreased after treatment. Anechoic areas were shown in 20 muscles (66.7%) before treatment, and disappeared or were reduced in size in 17 muscles (85.0%) Nutlin-3 after treatment. The pretreatment thickness was significantly related to visual analog scale (VAS) scores regarding posttreatment muscle pain and massage impression. The existence of anechoic areas was relevant to VAS scores regarding muscle pain.
Conclusion. Masseter thickness and existence of anechoic areas might be related to the therapeutic efficacy regarding muscle pain. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010;110:517-526)”
“Background: Left ventricular (LV)-only pacing has a significant effect on delay in depolarization of parts of the ventricles that are likely oversensed in the right atrial channel. The study aimed to assess the impact of ventricular activation sequence on QRS oversensing and far-field endless-loop pacemaker tachycardia (ELT) in patients who received cardiac resynchronization therapy (CRT) devices.
Methods: The study examined 102 patients
with CRT devices. Oversensing artifacts in the atrial channel were inspected on intracardiac electrograms, and their timing with respect to the beginning of QRS was determined during DDD-right ventricular (RV), DDD-LV, DDD-biventricular (BiV), and AAI pacing modes. The occurrence Selleck VX770 of ELT during DDD-LV pacing with a postventricular atrial refractory period (PVARP) of 250 ms was also assessed.
Results: The timing of oversensing artifacts (in relation to the beginning of surface QRS) was dependent on ventricular activation sequence, occurring promptly following intrinsic activation via the right bundle branch (47.1 +/- 26.4 ms), later during RV pacing (108.7 +/- 22.5 ms) or BiV pacing (109.4 +/- 23.1 ms), and significantly later, corresponding to the final part of the QRS, during LV pacing (209.6 +/- 40.0 ms, range: 140-340 ms, P < 0.001). Oversensing was significantly more frequent during LV than during RV pacing (35.3% vs 22.5%, P < 0.
