Veterinary Sciences, 2020 In avian medicine, Doppler sonographic techniques are used to visualize and estimate blood flow in the heart. In the literature there is a lack of standardized studies of the use of color Doppler flow on healthy avian species.

On systolic zeta functions [PDF]
European Journal of Mathematics, 2017 We define Dirichlet type series associated with homology length spectra of Riemannian, or Finsler, manifolds, or polyhedra, and investigate some of their analytical properties. As a consequence we obtain an inequality analogous to Gromov's classical intersystolic inequality, but taking the whole homology length spectrum into account rather than just ...

Arquivos Brasileiros de Cardiologia, 2008 FUNDAMENTO: O acoplamento eletromecânico (sincronia) do ventrículo esquerdo (VE) tem importância na análise da performance sistólica, especialmente para a indicação da terapia de ressincronização cardíaca em pacientes com ICC avançada. OBJETIVO: Comparar

Late systolic central hypertension as a predictor of incident heart failure : the Multi-Ethnic Study of Atherosclerosis [PDF]
, 2015 Background: Experimental studies demonstrate that high aortic pressure in late systole relative to early systole causes greater myocardial remodeling and dysfunction, for any given absolute peak systolic pressure.

Graphs of Large Girth and Surfaces of Large Systole [PDF]
, 2015 The systole of a hyperbolic surface is bounded by a logarithmic function of its genus. This bound is sharp, in that there exist sequences of surfaces with genera tending to infinity that attain logarithmically large systoles.

Systoles of hyperbolic manifolds [PDF]
Algebraic & Geometric Topology, 2011 We show that for every $n\geq 2$ and any $ >0$ there exists a compact hyperbolic $n$-manifold with a closed geodesic of length less than $ $. When $ $ is sufficiently small these manifolds are non-arithmetic, and they are obtained by a generalised inbreeding construction which was first suggested by Agol for $n=4$. We also show that for $n\geq 3$

Aortic valve stenosis: Prognosis and therapy [PDF]
Vojnosanitetski Pregled, 2003 There is a long latent period in the clinical course of aortic valve stenosis in adults. Symptoms usually occur in the case of critical stenosis, when aortic orifice area is under 0.7cm2 (0.4 cm2/m2).

Fear from the heart: sensitivity to fear stimuli depends on individual heartbeats [PDF]
, 2014 Cognitions and emotions can be influenced by bodily physiology. Here, we investigated whether the processing of brief fear stimuli is selectively gated by their timing in relation to individual heartbeats.

Systolic freedom of orientable manifolds [PDF]
, 1997 In 1972, Marcel Berger defined a metric invariant that captures the `size' of k-dimensional homology of a Riemannian manifold. This invariant came to be called the k-dimensional SYSTOLE.
