The cardiopulmonary baroreflex responds to an increase in central venous pressure (CVP) by decreasing total peripheral resistance and increasing heart rate (HR) in dogs. However, the direction of ventricular contractility change is not well understood. The aim was to elucidate the cardiopulmonary baroreflex control of ventricular contractility during normal physiological conditions via a mathem...

BACKGROUND Respiratory muscle function in patients with cystic fibrosis (CF) has been studied by measurement of maximal inspiratory pressure (P(Imax)), maximal expiratory pressure (P(Emax)), and the pressure-time index of the respiratory muscles (PTI(mus)). The maximum rate of pressure development (MRPD) during P(Imax) (MRPD-P(Imax)), MRPD during P(Emax) (MRPD-P(Emax)), maximal relaxation rate ...

Pharmacokinetic and pharmacodynamic variability largely account for interindividual differences in the response to antihypertensive drugs including angiotensin converting enzyme inhibitors. The factors determining the response to enalapril have been investigated in a placebo-controlled study in essential hypertension. The effects of placebo, the initial dose of enalapril, and long-term (1 and 6...

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...

Sixteen glass ceramic blocks (IPS e.max CAD/CAM) were fabricated by a CAD/CAM machine withdimensions (6mm × 11mm x 13mm) and divided into 4 groups (n=4), according to surface treatments: (G1)Hydrofluoric acid (HF) etching silane application, (G2) Acidulated phosphate fluoride (APF) silaneapplication, (G3) Monobond Etch Prime (MEP), (G4) Tetrabutylammonium dihydrogen trifluoride (TDTF) andsilane...

Abstract The prevalence of type 2 diabetes (T2DM) is higher in peripheral artery disease (PAD) than coronary (CAD) patients, and PAD overall confers cardiovascular risk CAD. purpose this study was to investigate how the incidence major events compares between CAD patients when analyses are stratified by presence (T2DM). We prospectively recorded death over 10.0±4.7 years 923 with stable CAD, wh...

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...
