Centrally mediated mechanism for pain adaptation may explain these findings, and the role of sEMG as a diagnostic tool for muscle pain needs to be carefully reconceptualized.”
“Polycrystalline samples

of Ca0.9-xSrxYb0.1MnO3-delta (x=0, 0.025.0.05, 0.1, and 0.2) were prepared VX-770 by a conventional solid-state reaction and their thermoelectric properties were evaluated at 303-973 K. Each of the samples consisted of a single phase with an orthorhombic structure. All the samples showed a metallic conductivity and their electrical resistivity was markedly affected by the distortion of the MnO6 octahedron. The Seebeck coefficient of all the samples was negative, indicating that the predominant carriers were electrons over the entire temperature range examined. The highest power factor achieved (0.22 mW m(-1) K-2 at 773 K) was shown by the sample with x = 0.1. The thermal conductivity was affected by both the crystal distortion and the difference in mass between the Ca2+ and Sr2+ ions. The highest dimensionless figure of merit obtained was 0.09 at 973 K for the sample with x = 0.1; this is a result of its low electrical resistivity and its moderate Seebeck coefficient and

thermal conductivity. (C) PP2 inhibitor 2009 American Institute of Physics. [DOI: 10.1063/1.3125450]“
“ObjectiveTo determine the rate of vasovagal (vv) complications in fluoroscopically guided interventional procedures.

DesignRetrospective case series analysis of prospectively collected data from March 8, 2004 to January 30, 2009.

SettingA single academic medical center.

SubjectsFour thousand one hundred eighty-three subjects undergoing 8,010 consecutive injections.

Outcome MeasuresPearson’s chi-square test was used to determine

the relationship between categorical Crenigacestat mw variables.

ResultsA total of 8,010 injections, including epidural steroid injections, radiofrequency nerve ablations, medial branch blocks, hip injections, knee injections, and glenohumeral injections were performed. Overall vv reaction rate was 2.6%, with 0.8% of procedures resulting in early terminated due to vv reaction. Peripheral joint injections had a vv rate of 0.2%, all occurring in hip injections. Transforaminal epidural steroid injections had a vv rate of 3.5%. Diagnostic blocks of the medial branches had the highest rate of vv (5.1%). Other predictors of vv reactions were identified including preprocedure pain score visual analog scale <5 (P=0.004), male gender (P<0.001), and age less than 65 years old (P<0.001).

Conclusionsvv reactions have an overall low occurrence rate (2.6%) in interventional procedures ranging from 0% in peripheral knee and shoulder injections to 5.1% in medial branch blocks. Conservative treatment of vv reaction and willingness to terminate procedures resulted in no serious adverse events related to vv reaction in 8,010 procedures.
