Les modes d'habitat à l'âge du Bronze en France
2018
The many discoveries made in preventive archaeology have drawn the picture of a highly anthropogenic landscape in Bronze Age France. Timber post buildings are the most common type of dwellings however other types of construction (sills, mudbrick, …) that have lighter foundations and are more susceptible to erosion are considered less common due to the inherent problems of identification. Small dwellings from 25 to 40 m2 with a quadrangular 1 to 3 aisled plan and built to house a nuclear family are the most common,. Other types of buildings differ from this standardised plan such as the long rectangular dwellings in Alsace dating to the Early Bronze Age (type Eching) or the Early Bronze Age …

Relationship between score and coaches’ verbal behavior
2013
Calpe V, Guzman J, Grijalbo C. Relationship between score and coaches’ verbal behaviour. J. Hum. Sport Exerc. Vol. 8, No. Proc3, pp. S728-S737, 2013. The way the coach act the most during the development of the game is meanwhile verbal behaviour directed to their players (Moreno et al., 2000), being it influenced by his own cognitions, motivations, and emotions, together with players behaviours and playing situation (Borrie, 1996; Smoll & Smith, 1989). The aim of this study was to analyse the relationship between a situational variable, the score during the game, and verbal behaviour of handball coaches in competitive situation. To do this, five coaches were analysed in five games. Two vari…
Activation pattern of signal transducers and activators of transcription (STAT) factors in inflammatory bowel diseases.
2005
Cytokine signaling pathways involving transcription factors of the signal transducers and activators of transcription (STAT) family play a key role in the pathogenesis of inflammatory bowel diseases (IBD). STAT proteins are latent cytoplasmic transcription factors that induce transcription upon phosphorylation, dimerization, and nuclear translocation. However, their activation pattern in IBD is poorly understood. The aim of our study was to characterize STAT-expression in IBD.Mononuclear cells were isolated from 36 colonic specimens of Crohn's disease, ulcerative colitis, or from control patients. Cells were stimulated overnight with antibodies against human CD2 and CD28 and mononuclear cel…
Embedded neural network system for microorganisms growth analysis
2020
This study presents autonomous system for microorganisms’ growth analysis in laboratory environment. As shown in previous research, laser speckle analysis allows detecting submicron changes of substrate with growing bacteria. By using neural networks for speckle analysis, it is possible to develop autonomous system, that can evaluate microorganisms’ growth by using cheap optics and electronics elements. System includes embedded processing module, CMOS camera, 670nm laser diode and optionally WiFi module for connecting to external image storage system. Due to small size, system could be fully placed in laboratory incubator with constant humidity and temperature. By using laser diode, Petri d…
LASCA and PPG imaging for non-contact assessment of skin blood supply
2013
Laser speckle contrast analysis (LASCA) offers a non-contact, full-field, and real-time mapping of capillary blood flow and can be considered as an alternative method to Laser Doppler perfusion imaging (LDPI). Photoplethysmography (PPG) is well known technique for assessment of skin blood pulsations that can be related to blood flow. In recent years several studies have been done on development of non-contact PPG imaging (PPGI). LASCA and PPGI techniques are simpler and cheaper compared with LDPI. LASCA technique has been implemented in several commercial instruments. However, these systems are still too expensive and bulky to be widely available. Several optical techniques have found new i…
3D segmentation of abdominal aorta from CT-scan and MR images
2012
International audience; We designed a generic method for segmenting the aneurismal sac of an abdominal aortic aneurysm (AAA) both from multi-slice MR and CT-scan examinations. It is a semi-automatic method requiring little human intervention and based on graph cut theory to segment the lumen interface and the aortic wall of AAAs. Our segmentation method works independently on MRI and CT-scan volumes and has been tested on a 44 patient dataset and 10 synthetic images. Segmentation and maximum diameter estimation were compared to manual tracing from 4 experts. An inter-observer study was performed in order to measure the variability range of a human observer. Based on three metrics (the maxim…
Flow cytometry diagnosis in myelodysplastic syndrome: Current practice in Latin America and comparison with other regions of the world
2019
Background: Flow cytometry (FC) is a valuable tool for the diagnosis of myelodysplastic syndromes (MDS). We present results of a survey carried out to evaluate FC current practice for MDS diagnosis in Latin America (LA), focusing on markers used and characteristics of the clinical diagnostic report. Compliance to IMDSflow recommendations was also evaluated. These practices were then compared with those used in other countries. Methods: An online survey was sent through the Grupo Latino-Americano de Mielodisplasia to LA cytometrists and other international scientific societies. Results: 91 responses from 15 LA countries were received. The median of the number of markers used was 20 +/- 4.5, …
EURECCA colorectal: multidisciplinary mission statement on better care for patients with colon and rectal cancer in Europe
2013
Contains fulltext : 125368.pdf (Publisher’s version ) (Closed access) BACKGROUND: Care for patients with colon and rectal cancer has improved in the last twenty years however still considerable variation exists in cancer management and outcome between European countries. Therefore, EURECCA, which is the acronym of European Registration of cancer care, is aiming at defining core treatment strategies and developing a European audit structure in order to improve the quality of care for all patients with colon and rectal cancer. In December 2012 the first multidisciplinary consensus conference about colon and rectum was held looking for multidisciplinary consensus. The expert panel consisted of…
Evidence for characteristic vascular patterns in solid tumours: quantitative studies using corrosion casts
1999
The vascular architecture of four different tumour cell lines (CaX, CaNT, SaS, HEC-1B) transplanted subcutaneously in mice was examined by means of microvascular corrosion casting in order to determine whether there is a characteristic vascular pattern for different tumour types and whether it differs significantly from two normal tissues, muscle and gut. Three-dimensional reconstructed scanning electron microscope images were used for quantitative measurements. Vessel diameters, intervessel and interbranch distances showed large differences between tumour types, whereas the branching angles were similar. In all tumours, the variability of the vessel diameters was significantly higher than …
