BACKGROUND The exact boundaries of the reentry circuit in atrioventricular nodal reentrant tachycardia (AVNRT) have not been convincingly defined. METHODS AND RESULTS To define the tachycardia circuit, single extrastimuli were delivered during AVNRT to 8 sites of the right intra-atrial septum: 3 arbitrarily divided sites of the AV junction extending from the His bundle (HB) site to the corona...

GUT and SUSY theories predict some relations among the fermion masses (or more properly among Yukawa couplings) at the unification scale, MGUT ∼ 10(GeV ) . For instance, in SU(5) we have the usual lepton-bottom quarks unification, hb = hτ , hs = hμ, hd = he, or the modified Georgi-Jarlskog relation, hb = hτ , hs = hμ/3, hd = 3he, while for SO(10) typically we get unification of the third family...

Axis specification and segment determination in dipteran insects are an excellent model system for comparative analyses of gene network evolution. Antero-posterior polarity of the embryo is established through systems of maternal morphogen gradients. In Drosophila melanogaster, the anterior system acts through opposing gradients of Bicoid (Bcd) and Caudal (Cad), while the posterior system invol...

BACKGROUND Recombinant erythropoietin has become a routine component of care of patients with chronic kidney disease reducing the need for blood transfusions but raising the risks for cardiovascular events. We undertook this secondary analysis of subjects enrolled in the Correction of Hemoglobin and Outcomes in Renal Insufficiency (CHOIR) trial to examine the interrelationships between epoetin-...

In the present work, an in-depth, qualitative and quantitative description of non-covalent interactions in the hydrogen storage materials LiN(CH3)2BH3 and KN(CH3)2BH3 was performed by means of the charge and energy decomposition method (ETS-NOCV) as well as the Interacting Quantum Atoms (IQA) approach. It was determined that both crystals are stabilized by electrostatically dominated intraand i...

background: predicting the incidence of tuberculosis (tb) plays an important role in planning health control strategies for the future, developing intervention programs and allocating resources. objectives: the present longitudinal study estimated the incidence of tuberculosis in 2014 using box-jenkins methods. materials and methods: monthly data of tuberculosis cases recorded in the surveillan...

We fabricated ordered GaAs/AlGaAs quantum dots (QDs) on patterned GaAs(0 0 1) substrates and investigated their optical properties by micro-photoluminescence (m-PL) spectroscopy. Sharp excitonic lines with single photon emission properties were observed. Polarization-dependent PL was performed to resolve the optical fine structure splitting of neutral excitonic lines and to identify the neutral...

introduction: glycemia and blood glucose levels are under the effect of hb a1c and therefore they could be considered as a valid index for the follow-up and control of diabetes .there are different and controversial reports on the effects of iron deficiency anemia on hb a1c. effects of ida in non diabetic patients are also unknown. the aim of the study was the comparison of hb a1c levels in hea...
