Heart failure is a leading cause of death in New Zealand. In order to determine the causesof rhythm disturbances leading to failure a knowledge of the structure and mechanical behaviour of cardiac tissue is important. This paper presents realistic stress and strain distributions for the passive heart that have been reproduced using a three-dimensional finite element model of the ventricles base...

We present the draft genome of an Oceanobacillus sp. strain isolated from spores found in soil samples from a burial crypt of the Cathedral of Sant'Antonio Abate in Castelsardo, Italy. The data obtained indicated the closest relation of the strain with Oceanobacillus caeni.

This study is focused on anomalous strain-rate-dependent behaviour of bacterial cellulose (BC) hydrogel that can be strain-rate insensitive, hardening, softening, or strain-rate insensitive in various ranges of strain rate. BC hydrogel consists of randomly distributed nanofibres and a large content of free water; thanks to its ideal biocompatibility, it is suitable for biomedical applications. ...

A strain of Spirochoeta refringens has been obtained in pure culture, and its morphological and cultural characteristics have been studied. The strain possessed no pathogenicity for rabbits or monkeys. It probably belongs to the genus Treponema, but it is easily differentiated from Treponema pallidum, Treponema microdentium, and Treponema macrodentium. Its relation to Spirochoeta balanitidis an...

We demonstrate the growth of ultra-thin AlN films on Si (111) and a GaN/sapphire (0001) substrate using atomic layer epitaxy in temperature range 360 to 420 °C. Transmission electron microscopy X-ray diffraction were used characterize interfaces, fine scale microstructure, crystalline quality thin films. Films deposited epitaxily with hexagonal structure, while substrate, film is epitaxial has ...

OBJECTIVES Previous studies have indicated an association between shiftwork and coronary heart disease. The increased risk could be due to job strain, which could act as a mediator of disease. There is also a possibility that interaction between shiftwork and job strain could occur that may induce or modify the development of disease. We conducted this study to explore the relation between shif...

background recently, assessment of the atrial motion and deformation indices obtained via doppler myocardial imaging (dmi) has been proposed as a new method of exploring the atrial function. objective our aim was to assess the right atrial (ra) regional function using myocardial velocities, strain, and strain rate imaging (sri) and compare it with the function of the inter-atrial septum (ias) a...

Background The degree and quantification of contractile dysfunction and myocardial scar in patients after acute myocardial infarction (AMI) has important prognostic implications. Myocardial deformation parameters like strain and strain rate have been shown to be more sensitive markers for contractile dysfunction than standard 2-D parameters. We sought to investigate whether strain and strain ra...
