To establish whether pressure-volume areas (PVAs) calculated using the maximum time-varying elastance (Emax) have a relation with myocardial oxygen consumption (MVO2) that improves on other indexes of myocardial oxygen demand, we studied nine dogs of either sex weighing 19-39 kg, which were instrumented with a micromanometer left ventricular (LV) catheter and a Wilton-Webster coronary sinus flo...

We present the variable-pressure luminescence spectra of crystals of isostructural palladium(ii) and platinum(ii) complexes with bis-N-benzyl-N'-3-methylpyridyldithiocarbamate (bmpDTC) ligands. The d-d luminescence band maxima Emax for these complexes are compared to others with different peripheral substituents on the dithiocarbamate ligands in the solid state. The comparison reveals significa...

Aim: To evaluate the cardiovascular effect of carvacrol treatment in a D(+)galactose accelerated aging model, investigating effects on vascular reactivity, oxidative stress, and systolic blood pressure (SBP).
 Methodology: Eight-week-old male Wistar rats (Rattus norvegicus) were used for oral eight weeks. Organ baths reactivity studies (FEN, ACh, NPS), fluorescence microscopy to detect rea...

BACKGROUND AND OBJECTIVES The removal of porcelain veneers using Er:YAG lasers has not been previously described in the scientific literature. This study was designed to systematically investigate the efficacy of an Er:YAG laser on veneer debonding, possibly without damage to the underlying tooth, and preservation of the veneer integrity. STUDY DESIGN/MATERIALS AND METHODS The Fourier Transfo...

Background Right ventricular-pulmonary arterial coupling plays an important role in the occurrence of right ventricular failure. Ventricular-arterial coupling is defined as Ea/ Emax. Ea is the effective arterial elastance and an index of the post-load, and includes vascular resistances, vessel compliance, vascular impedance, systolic and diastolic time intervals. Ea = (arterial end-systolic pre...

We construct efficient designs for the Michaelis-Menten enzyme kinetic model capable of checking model assumption. An extended model, called EMAX model is also considered for this purpose. This model is widely used in pharmacokinetics and reduces to the MichaelisMenten model for a specific choice of the parameter setting. Our strategy is to find efficient designs for estimating the parameters i...

Methods This retrospective study included subjects with PAH who a cardiac magnetic resonance (CMR) study within 14 days of cardiac catheterization between January 2009-August 2013. The effective elastance (Ea, index of arterial load) and right ventricular maximal end-systolic elastance (Emax, index of contractility) were determined by a combination of CMR and hemodynamic data. Ea is defined as ...

This study for the first time achieved an emission spectrometric analysis of the chemiluminescence of flavonoids in the presence of hydrogen peroxide, acetaldehyde and horseradish peroxidase, and revealed that the maximum emission wavelengths (Emax) strictly differ among catechins (E-max 630 nm), theaflavins (Emax 690 nm) and anthocyanins (Emax 675 nm) according to their chemical structures. Th...

An increasing number of new dielectrics are being reported for the development next-generation ceramic capacitors power electronics used in clean energy technologies. Here, high discharge density (Wdis) ~6.1 J cm−3 with efficiency (η)~72% under a pulsed field (Emax) 410 kV cm−1 is along temperature stability up to 150 °C (Emax = 200 cm−1) 0.5 K0.5Bi0.5TiO3-0.42BiFeO3-0.08Sm(Mg2/3Nb1/3)O3 (KBT-B...

Recommendations to obtain the best bonding silica-based ceramics are prepare its surface by hydrofluoric-acid HF etching and regular application of a silane. This study investigated how HF-etching following ultrasonic water bath cleaning (recommended protocol improve with composite resin), modifies chemistry lithium disilicate glass-ceramic impacts chemical Lithium discs (IPS Emax Press, Ivocla...
