AIMS It remains to be proven whether left ventricular (LV) peak systolic velocity indices (peak systolic annulus tissue velocities, ejection velocity, and strain rate) are more closely related to contraction than LV end-systolic echocardiographic indices (ejection fraction, fractional shortening, systolic annulus displacement, global strain, and ejection velocity time integral). The study aimed...

Four new species of Criconematoidea are described from Hoste Island, Chile. Criconema certesi n. sp. is distinguished by the fine, spine-like, cuticular extensions on body annuli; projection of annuli into rows of scales on posterior part of body; single, smooth, labial annulus set off by short collar from second (first body) annulus which is about same diameter as first (labial) annulus. Male ...

INTRODUCTION Adult mesenchymal stem cell therapy has a potential application in the biological treatment of disc degeneration. Our objectives were: to direct adipose-derived mesenchymal stem cells (AD-MSC) from the sand rat to produce a proteoglycan and collagen type I extracellular matrix (ECM) rich in known ECM components of the annulus fibrosis of disc; and to stimulate proteoglycan producti...

(A) The integrated marking feature allows for the placement of a colored are placed on or near the center of each of the coronary cusps in the en colored markers are individually dragged (table side control, using a stand level of the aortic annulus (left panel). These 2 separate steps result in the (long-axis location) of each coronary cusp of the native aortic valve. (C) to a position such th...

The persistent Hall voltage and current in an isolated annulus in a strong perpendicular magnetic field, at filling factor ν = 1/q, and in the presence of a weak constriction is obtained as a function of temperature, and flux piercing the annulus. A thermodynamic Hall conductance is found which has a universal value even with back scattering at the constriction.

The main purpose of this paper is to study the exceptional values of meromorphic function and its derivative on annulus. We also give some theorems and corollaries about exceptional values of meromorphic function on the annulus, which are the improvement of the previous results given by Chen and Wu.

Visual perception of a stimulus is a function of the visual context in which it is displayed. Surround suppression is a specific form of contextual modulation whereby the perceived contrast of a center stimulus is decreased by a high-contrast surround. Recent studies have demonstrated that individuals with schizophrenia are less prone to visual contextual effects, suggesting impairments in cort...

We aim at finding the reversal of radial SLE and proving the reversibility of wholeplane SLE. For this purpose, we define annulus SLE(κ,Λ) processes in doubly connected domains with one marked boundary point. We derive some partial differential equation for Λ, which is sufficient for the annulus SLE(κ,Λ) process to satisfy commutation relation. If Λ satisfies this PDE, then using a coupling tec...

Gas-lifted oil wells are susceptible to failure through malfunction of gas lift valve assemblies (GLV). One failure mode occurs when the GLV check valve fails and product passes into the well annulus, potentially reaching the wellhead. This is a growing concern as offshore wells are drilled thousands of meters below the ocean floor in extreme temperature and pressure conditions, and repair and ...

We read with great interest the report by Seiffert et al. (1) on the initial German experience with transapical implantation of a second-generation transcatheter heart valve for the treatment of aortic regurgitation. With the development of second-generation transcatheter aortic value replacement (TAVR) devices, TAVR indications have been expended to high-risk patients with pure aortic regurgit...
