Regional Lung Blood Perfusion Measured With Laser Doppler Method During Body Position Change, Valsalva Manoeuvre and Cardiopulmonary Bypass

2008

Regional Lung Blood Perfusion Measured With Laser Doppler Method During Body Position Change, Valsalva Manoeuvre and Cardiopulmonary Bypass Methodological approaches to investigate local regulatory mechanisms of lung blood supply in humans are restricted. We tried a new approach using laser Doppler technique. During bronchoscopy, an angled laser Doppler flow probe was introduced through a biopsy channel and wedged into small bronchus. Laser light penetrated the wall of small bronchus and was reflected from blood cells running through neighbouring capillaries. Regional blood perfusion changes were recorded during body position change from vertical to supine and back to vertical, while perfor…

A pig model of hepatic cryotherapy. In vivo temperature distribution during freezing and histopathological changes

2003

We aimed to assess the temperature distribution in the cryolesion during hepatic cryotherapy and the association with postoperative histological changes to optimise the technique and allow better preoperative planning. Hepatic cryolesions were produced in 22 pigs following laparotomy using a CMS-cryosystem and 8mm-AccuProbe-Cryoprobes. The temperature was measured in 1 min intervals at different distances from the probe during freezing. The animals were treated in 5 groups: (i) single freezing of 20 min; (ii) double freezing of 20 min each; (iii) single freezing of 40 min; (iv) single freezing of 20 min (n=4), histology at 1 week p.o., and (v) single freezing of 20 min and Pringle manoeuvre…

Papillon Lefevre syndrome: bridge between Dermatologist and Dentist

2010

Papillon-Lefevre syndrome is a rare autosomal recessively inherited condition which shows features common to both dentistry and dermatology. This disease is characterized by palmoplantar hyperkeratosis and severe periodon- titis. Therefore both the dentist and the dermatologist should be aware of the same because an early diagnosis of the syndrome can help to preserve the teeth by early institution of treatment, using a multidisciplinary approach. Here we present a case report of Papillon-Lefevre syndrome, along with a comprehensive review of the etiology, pathology, clinical features, differential diagnosis and management of the condition.

Effet du statut organique des sols pollués sur la dynamique et l'impact du cuivre sur les communautés microbiennes

2009

National audience; L’effet du statut organique des sols (SOS) sur l’impact du cuivre a été évalué par une approche en microcosmes et lysimètres d’un sol de vigne amendé en diverses matières organiques lors d’une expérience de terrain de long terme. Des microcosmes et des lysimètres du sol de vigne ont été contaminés à 240 mg Cu kg-1 et incubés à 23°C pendant 12 mois. La distribution et la dynamique du cuivre ont été caractérisées par fractionnement granulométrique et spéciation solide en extraction séquentielles et par spéciation liquide par mesure de concentration de cuivre échangeable total (ICP-AES), libre (électrode sélective) et biodisponible (biosensor). L’impact du cuivre sur les com…

Influence Des Conditions De Fabrication Sur Les Propriétés Mécaniques Et Physico-Chimiques D'un Composite Lin/Époxy Unidirectionnel

2017

This study focused on the development of a manufacturing process of laminated composites made from DGEBA epoxy matrix and flax fibers. The aim is to produce a material with good and low dispersed mechanical properties. Thermocompression is the chosen manufacturing method because it enables the production of composite with high fiber content. We used separated matrix and reinforcement, and not a prepreg, to fully control each component of our composites. Several curing cycle parameters have been tested in order to optimize mechanical properties and processing time. A multi-scale analyze has been carried on the produced composites in order to quantify the range of properties’ modifications. T…
