INTRODUCTION AND OBJECTIVES To investigate the relationship between patent foramen ovale and cryptogenic stroke in patients aged > or =55 years. METHODS This prospective study determined the presence of patent foramen ovale and atrial septal aneurysm using transesophageal echocardiography in 262 consecutive patients with a diagnosis of probable cryptogenic stroke. Data from 44 patients aged >...

Abstract The effect of high pressure processing (300 and 600 MPa) combined with mild heat treatment (55 75 °C) on the colour parameters, anthocyanin content, sensory characteristics strawberry puree were examined after treatments 2 weeks cold storage at 15 °C. As an industrial scale simultaneous implementation these remains a challenge, HHP carried out consecutively in different sequences. para...

The interest in using the pseudoelastic properties of NiTi wires in orthodontic practice arises chiefly from the expectation that they can afford low continuous forces at constant temperature. The reversion force developed by NiTi archwires depends, however, upon temperature since the superelastic force follows a Clausius-Clapeyron like equation. Actually the oral environment temperature is mod...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a worldwide disruption of global health putting healthcare workers at high risk. To reduce the transmission SARS-CoV-2, in particular during treating patients, our team aims to develop an optimized isolation chamber. The present study was conducted evaluate role temperature elevation against SARS-CoV-2 viability, whe...

The heat resistance of 35 Salmonella strains was determined at 55 to 65 °C. No correlation between the heat resistance and the origin of the Salmonella spp. could be established. D-values in chicken broth, using a linear regression, of an 8 Salmonella serotype cocktail were 4.87, 2.72, 1.30, and 0.41 min at 55, 58, 60 and 62 °C, respectively. Using a linear model, the D-values ranged from 4.86 ...

The morphology and cell wall composition of Bacillus coagulans, a facultative thermophile, were examined as a function of growth temperature. The morphology of the organism varied when it was grown at different temperatures; at 37 C the organism grew as individual cells which increased in length with increasing growth temperature. At 55 C it grew in long chains of cells. Cell wall prepared from...

Anaerobic digestion is now commonly used for sludge treatment. Most industrial digesters operate under mesophilic (37°C) or thermophilic (55°C) conditions. These two regimes are considered as optimal for methane production. In this work, continuous sludge digestion has been operated at labscale at 5 different temperatures comprised between 28° and 55°C. The reactors were first inoculated with a...
