Obstructive hypertrophic cardiomyopathy is a complex pathology. The understanding of its physiopathology and, notably, of the SAM phenomenon (Systolic Anterior Motion), is crucial for all available treatments. Amongst the most efficient therapies, one can cite the septal myectomy and its most recent technical updates, as well as the alcohol septal ablation. The choice between these two methods depends on the general state of the patient, the thickness of the interventricular septum and the coronary anatomy of the patients. [less ▲]

This paper presents new developments to maximize the number of ship blocks and ship sections produced in various workshops of shipyards during a certain time window. The visualization tool OptiView® was developed to support users to improve the space utilization and workshop productivity. The software is coupled with a heuristic optimisation solver. The paper describes the approach to the space allocation problem and gives three application examples. [less ▲]

A major challenge in prostate cancer oncology is to develop more accurate imaging assessments than those currently available. Indeed, an efficient imaging technique which significantly improves the sensitivity and specificity of the diagnostic and predicting the cancer behaviour would be extremely valuable. This project intends to prove the concept of using optoacoustic imaging in combination with biologically functionalized nanoparticles as an integrated biosensor based system for the production of specific and sensitive data for accurate diagnosis of prostate cancer. This concept results on the use of contrast agents which transform an incident luminous energy into local heating inducing a pressure wave detectable by acoustic (echography). For the optoacoustic detection, the nanoparticles used must present a maximum of absorption in the optical transparency window of the human tissues in order to allow their and subsequently the tissue specific excitations while avoiding unwanted destructive energy transfers. According to these characteristics (energy transfer by thermoelastic reaction), rod-like gold nanoparticles (stick form) with a maximum of absorption towards 760 nm were produced by using a “bottom-up” approach with dynamic templates (surfactant). These nanoparticles are then coupled with an antibody directed against the cancerous cells to guarantee the specific detection of the particles. The development of the biosensor is firstly performed to target the Prostate Specific Membrane Antigen (PSMA), a transmembrane protein considered as a suitable biomarker for prostate cancer. Detection and localisation of PSMA on LNCaP fixed cell surface was performed by immunostainning on monolayer cell culture and on spheroid slices. Then, by backscattered electron (BSE) microscopy analysis and two-photon luminescence imaging, detection of nanoparticles on fixed and living cell surface shows the successful binding of the biosensor to the cells expressing PSMA. In prospect, the detection of the biosensor will be tested on spheroids, on human biopsies and finally on in vivo models (mouse xenograft models). [less ▲]

The multiobject spectrograph OPTOPUS, for use at the 3.6-m ESO telescope with the CCD detector, is described, and preliminary results of spectra obtained in December 1985 of selected regions in the coma of Halley's comet are presented. The instrument's 54 separately cabled optical fibers, whose input ends are located in the focal plane by connectors plugged into drilled starplates, enable light to be guided from freely distributed points in a 33 arcmin zone of the Cassegrain focal plane, to a common slit. The spectra show the presence of a very faint continuum, due to the scattering of solar line photons in the inner region of the coma, on which is superimposed the bright emission bands of molecules such as CN, C2, C3, and NH2. The spectra also indicate that the brightness decrease of molecular bands as a function of the projected radial distance is not the same for different molecules. 3-3 (PDF) ESO [less ▲]

Au grand mécontentement général, le prix du pétrole augmente irrésistiblement. Malgré cela, notre société ne semble pas disposée à changer ses habitudes. [...] Ces mois de vacances ont été riches en catastrophes climatiques. Ainsi, en Afrique de l'Ouest, des milliers de personnes ont disparu suite à une longue famine consécutive à un ciel resté trop longtemps avare en précipitations. En Méditerranée occidentale, on ne compte plus les milliers d'hectares de forêt partis en fumée à cause de la sécheresse. Au même moment, l'Europe centrale et orientale est lasse de patauger dans l'eau. Les spécialistes qualifient ces inondations comme étant les plus graves qu'aient connues la Suisse et la Roumanie. L'Inde est également noyée alors que Taïwan se prépare à la tempête la plus violente de son histoire. Et après ces préliminaires dramatiques, voici Katrina qui sème chaos et désolation.
