AIM After pulmonary vein isolation (PVI), dormant conduction (DC) is present in at least one vein in a substantial number of patients. The present study seeks to determine whether there is a relationship between poor contact forces (CF) and the presence of DC after PVI. METHODS AND RESULTS This prospective, operator-blinded, non-randomized dual-centre trial enrolled 34 consecutive patients wi...

Inhibitors of the enzyme farnesyl protein transferase prevent a key step in the post-translational processing of the Ras protein, and were developed initially as a therapeutic strategy to inhibit cell signalling in ras-transformed cells. As more has been learnt about the biological effects of farnesyl transferase inhibitors (FTIs) on cancer cells, it is clear that tumours without oncogenic ras ...

Sixty six clinically proven hypothyroid subjects were studied using radioimmunoassay techniques for estimation of serum thyroid hormones and pituitary TSH concentrations. The mean level for serum TSH was significantly elevated while the mean levels for serum T4, 13 and Free T4 were significantly low. A significant positive correlation was found between 14 and T3 and between T4 and FTI. Serum TS...

We study the surface state-dependent magneto-optical properties of an ultrathin Floquet topological insulator (FTI) under influence external perpendicular magnetic field in terahertz frequency regime. Under picture, we treat circularly polarized off-resonant light as perturbation that introduces a mass gap at Dirac cone, thus, making state fermions massive. By tuning optical energy FTI thin-fil...

Both systolic pressure-volume area (PVA) and force-time integral (FTI) have been used as measures of oxygen consumption per beat (VO2) in the isolated left ventricle. The reciprocal of the slope of the VO2-PVA relation has been considered to reflect the chemomechanical energy transduction efficiency of the contractile machinery (contractile efficiency), whereas its VO2 intercept consists of ene...

Background Similar to speckle tracking echocardiography cardiac MR (CMR) feature tracking imaging (FTI) uses a 2-dimensional deforming analysis of the myocardium which allows quantitative evaluation of myocardial motion and contractility. This technique might provide important additional information in children, including those with congenital heart disease (CHD). Until now, there are no refere...

The concentration of thyroxine-binding globulin (TBG) in the serum can now be measured by direct assays that are simple and inexpensive. Comparison of a direct measurement of TBG concentration with a widely used indirect method (Thyopac-3) showed that the indirect method was inaccurate when TBG concentrations were high. This will result in an increase in the derived free thyroxine index (FTI), ...

Sustainable methods of practice within the fashion and textile industry (FTI) often strive to employ a circular economy that aims eliminate waste through continual use resources. Complex problems such as waste, consumption, overproduction are heavily intertwined; main aim this paper is report on research focused re-examining potential food streams commercially viable source raw materials for FT...
