OBJECTIVE We investigated whether the Frank-Starling mechanism is absent or preserved in end-stage failing human myocardium and if phosphorylation of contractile proteins modulates its magnitude through the sarcomere length-dependence of calcium sensitivity of isometric force development. METHODS The effect of phosphorylation of troponin I and C-protein by the catalytic subunit of protein kin...

In this paper simple quartic trigonometric polynomial blending functions, with a tensionparameter, are presented. These type of functions are useful for constructing trigonometricB´ezier curves and surfaces, they can be applied to construct continuous shape preservinginterpolation spline curves with shape parameters. To better visualize objects and graphics atension parameter is included. In th...

In this note we prove only the important special case (1.1), omitting the parts of the argument required for other cases. In addition, we present an alternate proof, dating from 2002, of the lower bound implicit in (1.1). This proof avoids the use of results about uniform order statistics required in [3], and instead utilizes the cycle lemma from combinatorics. Although shorter and technically ...

A binary gravitational rotator, also called the two-body problem, is a pair of masses m1, m2 moving around their center-of-mass (com) in own field. In Newtonian gravitation, problem can be described by single reduced mass (gravitational rotator) mr = m1m2/(m1+m2) orbiting total m m1+m2 situated com distance r, which between two original masses. this paper, we discuss rotator Newtonian, Schwarzs...

various scaling methods such as relative viscosity, peclet and reynolds scaling were used to find the best scaling law. scaling and modeling of the flow curves of various model emulsions consist of tragacanth gum (tg) (0.5, 1 % wt), oleic acid (5, 10% v/v) and wpi (2, 4 % wt) were investigated and the best models were selected. as these emulsions are non-newtonian, they do not obey the usual, si...

To assess the influence of the autonomic nervous system upon the recovery of the normal human sinus node, the responses to overdrive pacing at multiple cycle lengths of the denervated donor heart sinus nodes of 18 human cardiac transplant recipients were compared to the responses of those 18 patients' innervated, remnant atria and of 20 control subjects with normal sinus node function. The mean...

BACKGROUND AND OBJECTIVES In order to provide a good match between donor and recipient in liver transplantation, four scoring systems [the product of donor age and Model for End-stage Liver Disease score (D-MELD), the score to predict survival outcomes following liver transplantation (SOFT), the balance of risk score (BAR), and the transplant risk index (TRI)] based on both donor and recipient ...

Aims: The purpose of this study was to investigate the role of spiritual well-being and demographic characteristics in signing the donor card. Instrument & Methods: This cross-sectional study was conducted in Hamadan in 2018. Six hundred employees from 57 offices (out of 60) were selected using a random sampling method. Data gathering was carried out using a self-administered questionnaire. Th...
