“The operation
of visible-sensitive gaseous and to some extent, vacuum-photomultipliers is critically affected by secondary electrons originating from ion impact on the photocathode. A simple method for indirect measurement of the effective ion-induced secondary-electron emission (IISEE) coefficient from the photocathode into a gas medium gamma(eff)(+) was developed. The experimental results with visible-sensitive K-Cs-Sb, Na-K-Sb, and Cs-Sb photocathodes, yielded gamma(eff)(+)-values between 0.02 and 0.03 in Ar/CH(4)(95/5) at 700 mbar; these are in good agreement with theoretical calculations. The corresponding vacuum IISEE BV-6 molecular weight https://www.selleckchem.com/products/shp099-dihydrochloride.html coefficients gamma(+) were estimated, based on a theoretical model, to be 0.47, 0.49, and 0.47 for K-Cs-Sb, Na-K-Sb, and Cs-Sb photocathodes, respectively. The ratio of gas gamma(eff)(+) and vacuum gamma(+) IISEE coefficients, calculated to be similar to 0.06, is the fraction of secondary electrons surmounted the backscattering in the gas media.

“Background: The diagnosis of the impaired left ventricle (LV) diastolic function during atrial fibrillation (AF) using
traditional methods is very difficult. Natriuretic peptides seem to be useful for assessment of diastolic function in patients with AF.
Aim: To evaluate
the influence of LV diastolic dysfunction on natriuretic peptides concentrations and to assess the diagnostic value of atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP) in patients with AF and impaired LV diastolic function.
Methods: The study included 42 patients (23 males, 19 females), aged 58.6 +/- 8.2 years with nonvalvular persistent AF with preserved LV systolic function who were converted into sinus rhythm by DC cardioversion (CV) and maintained sinus rhythm Tideglusib nmr for at least 30 days. Echocardiography (ECG), ANP, and BNP level measurements were taken at baseline 24 hours before CV and 24 hours and 30 days after CV. On the 30th day following CV in patients with sinus rhythm, Doppler ECG was performed to assess LV diastolic function.
Results: Thirty days after CV, normal LV diastolic function in 15 patients and impaired diastolic function in 27 patients was diagnosed: 20 with impaired LV relaxation and seven with impaired LV compliance. During AF and 24 hours, and 30 days after sinus rhythm restoration, significantly higher ANP and BNP levels were observed in patients with LV diastolic dysfunction as compared to the subgroup with normal LV diastolic function. The average values of ANP during AF in patients with normal and impaired diastolic function were 167.3 +/- 70.1 pg/mL and 298.7 +/- 83.6 pg/mL, respectively (P < 0.
