Introduction : Le projet TADAM, une étude contrôlée randomisée, comparait un nouveau traitement assisté par héroïne avec des traitements existants par méthadone à Liège, en Belgique. Nous avons réalisé une étude qualitative sur l'attitude des personnes dépendantes de l'héroïne envers ce type de projet, ainsi que sur l'attitude des intervenants d'institutions de soins travaillant avec ces personnes Méthode : Avant qu'un patient ne soit inclus dans le projet TADAM, il lui était demandé d'expliquer pourquoi il souhaitait rentrer en traitement (n=80). Des interviews ont également été réalisées auprès de consommateurs d'héroïne non inclus dans le projet, avant la période d'inclusion (n=65), au milieu de celle-ci (n=30) et dans ses derniers mois (n=23). Pendant le projet, des interviews ont également été réalisées auprès d'intervenants travaillant dans des institutions de soins pour personnes dépendantes de substances, soit de manière individuelle (n=10), soit en groupe (n=6) pour connaître leur attitude face au projet TADAM. Résultats : De nombreux patients souhaitaient rentrer dans ce projet pour améliorer leurs conditions de vie. La raison principale de ne pas rentrer dans ce type de traitement était la peur de devenir plus dépendant. Cette raison était renforcée par le fait que le traitement par héroïne proposé ne durait que 12 mois et les patients s'inquiétaient de leur situation après ce traitement : ils avaient peur d'être plus dépendants et donc dans une situation plus difficile qu'avant le traitement. L'attitude des intervenants étaient plutôt favorable mais prudente. Conclusion : Contrairement aux craintes préalables, les usagers d'héroïne ne se précipitent pas en masse et sans réfléchir vers un traitement assisté par héroïne. Certains réfléchissent longtemps avant de s'y engager. Une information précise et un traitement sans durée minimum sont nécessaires. [less ▲]

Aim. The objective of this study was to use in vivo PET/CT imaging as a validation tool for a novel human colorectal carcinoma model being developed in chicken chorioallantoic membrane (CAM). For this initial pilot study a cell line modeling colon cancer was selected and imaged using [18F]fluorodeoxyglucose (FDG). <br />Materials and methods. A window was made in the shell of fertilized chicken eggs and 3x106 SW1222 human colorectal carcinoma cells were implanted at day 10 post-fertilization. On day 17 the shell window was enlarged to allow direct injection of FDG (12.2 ± 4.5 MBq/egg) into a CAM blood vessel. During injection the egg was warmed on a heating pad. A mixture of ketamine/medetomidine (50 :1 mg/ml, 0.2 ml/egg) was injected into the albumin in some eggs to assess the effect of anesthesia. After FDG injection the egg was returned to the incubator for a 45 min uptake period before imaging. Imaging was performed on a Siemens Focus 120 microPET with structural CT on a General Electric eXplore CT120. A Minerve cell system allowed reproducible positioning between modalities. PET data was acquired in list mode before histogramming into a single 10 min frame for reconstruction using a 3D maximum a posteriori (MAP) method with all corrections except scatter. A standard 100 µm (theoretical) image resolution protocol (70 kV, 50 mA, 32 ms, 220 views) was used to obtain structural CT data. Image coregistration was performed in PMOD version 3.3. In a separate egg, the influence of added contrast on the CT data was investigated by adding iodinated contrast agent (Iobitridol 35 mgI/ml) to the albumin. <br />Results. FDG uptake was clear in chick and tumor, with notably high uptake at the major joints. Tumors were identified by localization of FDG uptake on the surface of the CAM. A lack of soft tissue contrast between tumor, CAM and albumin made precise structural identification of the tumor difficult. Anesthesia was crucial to image quality in both PET and CT. CT contrast between the soft tissues of the chick and surrounding albumin/structures was improved by addition of contrast agent. <br />Conclusion. For the first time we demonstrate successful imaging of FDG uptake in a human colorectal carcinoma chicken CAM model in ovo. Methods to improve structural data are under investigation and will be used in further studies. With such improvement, this model could be of great value to PET oncology imaging. [less ▲]

This paper is the first of a series considering the properties of distribution of nearby galaxies in the low density regions. Among 7596 galaxies with radial velocities V_{LG}<3500 km/s, absolute magnitudes M_K<-18.4^m$, and Galactic latitudes |b| >15 degr there are 3168 field galaxies (i.e. 42%) that do not belong to pairs, groups or clusters in the Local universe. Applying to this sample the percolation method with a radius of r_0=2.8 Mpc, we found 226 diffuse agglomerates with n>=4 number of members. The structures of eight most populated objects among them (n>=25) are discussed. These non-virialized agglomerates are characterized by a median dispersion of radial velocities of about 170 km/s, the linear size of around 6 Mpc, integral K-band luminosity of 3*10^{11} L_sun, and a formal virial-mass-to-luminosity ratio of about 700 M_sun/L_sun. The mean density contrast for the considered agglomerates is only <Delta n/\bar{n}\gtrsim 5, and their crossing time is about 30-40 Gyr. [less ▲]

Il sera ici question de phénomènes réflexifs qui, au sein d’un texte littéraire, produisent des écarts sensibles et rompent le processus classique de la représentation du réel. Les cas rencontrés sont étonnamment divers, tant en ce qui concerne leur structure que les effets produits. C’est pourquoi l’on se propose de les classer en six catégories distinctes : réflexivité autotélique, réflexivité poétique, réflexivité linguistique, réflexivité de l’énonciateur, réflexivité conative et réflexivité référentielle.

Ultrasound techniques allow examination of some parts of the suspensory ligament (SL) but "anomalies" are regularly observed. Their significance is not known. Few studies have described the relationship between ultrasonographic appearance and the exact morphology in histological sections. The aim of this study is to develop good techniques for cutting, staining, and showing the variation in the tissue composition within the SL. The SLs from the right limbs of 11 horses were collected. Samples were taken from cross-sections at six levels of the SL and they were embedded in paraffin or in Tissue-Tek®. Most of the paraffin sections were shredded. By using the cryosection technique, some freezing artifacts (holes) appeared. Therefore, a technique of freezing with cryoprotection was carried out, which produced the best results. Hematoxylin-phloxine-saffron gives a good contrast of colors between the tissues observed allowing the use of an image analysis program. The percentage of each tissue within the SL for each section and for six levels of the ligament was calculated. Results were analyzed by SAS software. The muscle tissue (PMT) and adipose tissue (PAT) decreased significantly (p < 0.0001), whereas the connective tissue (PCT) increased significantly (p < 0.0001) with age and when descending from the proximal to the distal level of the SL. The PMT was significantly higher (p < 0.0001) in females than males, while the PCT was significantly higher (p < 0.0001) in males than females. The PAT was significantly higher (p = 0.0278) in hindlimbs than in forelimbs. [less ▲]

The aim of the present study is to compare the effect of different steam explosion treatments on physicochemical properties and hydrolysis rate of a pure bleached cellulose. The results showed that moderate steam explosion treatments (severity factor below 5.2) did not improve the enzymatic hydrolysis rate of the cellulose fibers. The characterization of the obtained samples showed an increase of the cellulose accessibility coupled with an increase of the overall crystallinity of the substrate. In these conditions, the higher accessibility is counterbalanced by the increased crystallinity. Indeed, a greater proportion of the substrat is accessible by only a fraction of the enzymatic complex (exo-glucanases) activities. When the severity factor reached 5.2, a decrease of the cellulose enzymatic hydrolysis rate was observed. In this case, TGA analysis showed an increase of the char level at the end of the pyrolysis which traduced an important thermal degradation of the samples. The thermal degradation of cellulose lead to an important change in substrate composition, which induced a decrease of the cellulose ratio available for hydrolysis and caused a decrease of the hydrolysis yields.

Polyphenols have favorable antioxidant potential on human health suggesting that their high content in apple is responsible for the beneficial effects of apple consumption. They are also related to the quality of ciders as they predominantly account for astringency, bitterness, color and aroma. Five groups of phenolic compounds are described in the apple fruit: flavanols, hydroxycinnamic acids, dihydrochalcones, flavonols and anthocyanins. So far, only two studies have been published on the genetic basis of the phenolic content of dessert apples. As cider apples are commonly described to be much more concentrated in phenolic compounds than dessert varieties, the present study focuses on a cider apple progeny. 32 compounds belonging to the five groups were identified and quantified by HPLC-UV and UHPLC-UV-MS/MS in fruit extracts and juices. 53 QTL controlling phenolic compounds concentration were detected on nine linkage groups (LG) on the integrated linkage map, for all phenolic groups except anthocyanins. QTL clusters located on LG1, 12, 14, 15 and 17 were stable across the year or the studied material. QTL detected on LG1, 14 and 17 for quercitrin, p-coumaroylquinic acid, rutin and chlorogenic acid confirmed results of previous studies. However, no significant QTL was obtained on the LG16 where a major locus for flavanols was previously located. With the two previous studies, this study shows the diversity of genomic regions controlling traits of interest in apple. [less ▲]
