“…In former two studies, absence of a significant reduction in sP-selectin level after successful PMBV might be caused by persistent AF that may mask the positive influence of PMBV on platelets. Since warfarin therapy can also affect platelets functions, short term cessation of warfarin therapy prior to the PMBV is another problematic issue about these studies (25,26). In present study all patients was in sinus rhythm and no patient was on warfarin therapy.…”

“…In JK we have already derived interrelations for the high-quality light curves of a sample of 74 stars. Since this is a relatively small sample, and as a result the corresponding relations may be too restrictive, here we derive formulae based on an extended sample of 257 stars (a subsample of the data set used in KJ and Kovács & Jurcsik 1997). The ranges of the Fourier parameters are listed in Table 1, whereas the new relations are given in Table 2.…”

In order to make an in‐depth comparison between theory and observations, we analyse the light and velocity curves of various hydrodynamical models simulating RRab stars. The observations are represented by empirical formulae, derived in this and our earlier papers. It is shown that the overwhelming majority of the models tested do not follow the empirical relations regarding the shape of the light curves and the physical parameters. In almost all cases the luminosities predicted from the model light curves are significantly lower than the corresponding model values. The overall discrepancy of the models is an important indication of the limitation of the applicability of the present theoretical light and velocity curves in the determination of the physical parameters of these stars. In transforming the theoretical data to the observed light curves in V colour and in computing the observed radial velocities, it is shown that both bolometric correction and tracing the line‐forming regions have considerable effects on the evaluation of the observed quantities. In an effort to resolve the discrepancy between theory and observations, it is suggested that a proper evaluation of the bolometric correction and radial velocity based on complete dynamical atmosphere models may be a useful step in this direction.

We present the results of a photometric study of RR Lyrae variables in the field of the globular cluster M55. We have discovered nine new RR Lyrae stars, increasing the number of known variables in this cluster to 15 objects. Five of the newly discovered variables belong to Bailey type RRc and two to type RRab. Two background RRab stars are probable members of the Sagittarius dwarf galaxy. Fourier decomposition of the light curves was used to derive basic properties of the present sample of RR Lyrae variables. From an analysis of the RRc variables we obtain a mean mass of M = 0.53 ± 0.03M ⊙ , luminosity log L = 1.75 ± 0.01, effective temperature T ef f = 7193 ± 27 K, and helium abundance Y = 0.27 ± 0.01. Based on the B − V colors, periods and metallicities of the RRab stars we estimate the value of the color excess for M55 to be equal to E(B − V ) = 0.11 ± 0.03. Using this value we derive the colors of the blue and red edges of the instability strip in M55. The blue edge lies at (B − V ) 0 = 0.20 mag and the red edge lies at (B − V ) 0 = 0.38 mag. We estimate the values of the visual apparent and dereddened distance moduli to be 13.65 ± 0.11 and 13.31 ± 0.11, respectively. The light curves of three of the RRc variables exhibit changes in amplitude of over 0.1 mag on the time scale of less than a week, rather short for the Blazhko effect, but with no evidence for another radial pulsational frequency. However we do detect other periodicities which are clearly visible in the light curve after removing variations with the first overtone radial frequency. This is strong evidence for the presence of non-radial pulsations, a behavior common for δ Scuti stars but not yet observed among RR Lyr variables.
