The livestock sector plays a dynamic role in the economic development of rural areas in Algeria. Due to its adaptation to harsh environments, goat breeding is practiced in many areas of the country. To the north, it is confined to mountainous areas, but the bulk of the workforce is left in the steppe and semi-desert areas. The goat population in Algeria reached 3.8 million heads, ranking second after sheep. The present work contributes to a better characterisation of local goat in Kabylie for production and reproduction traits. The study was conducted in the regions of Chemini (Bejaia province) and Bouzeguene (Tizi-Ouzou province). A survey was conducted in 29 herds. The results revealed that the overall mean of goats per households was 6.69 ± 2.97. The purposes of keeping goat in Chemini and Bouzguene was private consumption of milk (82.76%) and meat (68.97%) as well as for commercial exchange (62.07%). The Kabyle goat is small (male: 62.23 cm and female: 58.41 cm) with long hair. Its ears are drooping, its convex profile has a slightly pronounced nasal split and its coat colour ranges from dark brown to black. However, the crossbreeding with exotic breeds (mainly with Saanen goat), controlled or uncontrolled, increased the frequency of white coat. The average age at puberty in males was 6.93 ± 1.04 and 7.38 ± 0.94 months in females. The reported age at first kidding and kidding interval were 13.03 ± 0.87 months and 7.83 ± 1.29 months, respectively. [less ▲]

Il existe des parentés remarquables entre certaines caractéristiques du roman d’aventures et les premières fictions d’anticipation françaises. Il n'y a pas seulement que la notion d’"aventure" est floue, composant une catégorie infiltrante tenant de l’hypergenre ou du genre parasite, mais il existe aussi des propriétés communes formant un genre hybride de « science-fiction d’aventures» qui compose un corpus important, pourtant peu considéré par les études littéraires consacrées au récit d'anticipation. Envisagé sous cet angle, tout un pan de la production d’anticipation de la seconde moitié du XIXe siècle apparaît comme marqué par le déplacement géographique autant sinon davantage que par le voyage temporel, cultivant une plasticité qui permet dans certains cas des reprises à l’identique ou presque. Ce sont ces procédés d’hybridation qui font l'objet de cette communication, à partir d’un type de récits généralement considéré comme un sous-genre matriciel de l’aventure, la robinsonnade, considérée dans quatre romans du dernier quart du XIXe siècle: André Laurie, Les Exilés de la Terre; Georges Le Faure, Les Robinsons lunaires; Jules Verne, L'Île à hélice; Paul Adam, Lettres de Malaisie.

The objective of this study was to evaluate the effects of the inclusion of Urtica dioica leaves meal in diets on growth performances and carcass characteristics of broiler chicken. The study was conducted from May to June 2014 in the area of Chemini (Algeria). In a completely randomized design, a total of 100 one-day-old broilers (industrial strain) were divided into 2 groups and 2 repetitions with 25 chickens each. Group 1 was the control group fed a standard commercial diet based on corn and soybean purchased on the local market, whereas the birds in group 2 were fed the nettle diet (control diet with addition of 2% of nettle). The animals were housed inside in experimental pens and fed ad libitum. The results showed that nettle inclusion significantly promotes growth performance of broilers at 42 days of age (1644.8 ± 45.5 vs. 1565.1 ± 45.5g; P<0.05). The broilers fed the nettle diet had higher thigh yield (26.0 ± 0.3 vs. 25.2 ± 0.3%; P<0.05) but lower abdominal fat yield (4.39 ± 0.16 vs. 3.90 ± 0.16%; P<0.05). No significant effect of the diet was observed for carcass yield (around 71.1%) and breast percentage (around 32.40%). The overall mortality was not significantly different (P>0.05) for any of the dietary regimens (around 20%). Feed conversion ratio of the two groups were very close (around 2.17). This experiment showed that dietary inclusion of Urtica dioica has positive effects on growth performance and carcass quality of broilers. [less ▲]

A l’heure actuelle, la vision prégnante du vieillissement est négative, teintée des phénomènes d’âgisme et de jeunisme. Cette vision est objectivée dans diverses enquêtes récentes (ex : l’Eurobaromètre des statistiques de discrimination en Europe) qui soulignent que le motif de discrimination le plus souvent cité en Europe est l’âge (correspondant ici au fait d’avoir plus de 55 ans ; 4 % en 2012, 6 % en 2009), suivi seulement par la race (3 %). Si la personne vieillissante est déjà stigmatisée en général, il n’est pas étonnant de constater que le fait d’être atteint d’une pathologie démentielle accroît encore ce phénomène : les individus souffrant de démence sont considérés comme faisant partie du groupe le plus marginalisé et stigmatisé dans la société (Graham et al., 2003). Les personnes qui en sont atteintes sont souvent perçues comme n’ayant plus une bonne qualité de vie (Qdv) ni la capacité d’éprouver du plaisir (Garand et al., 2009). En ce sens, ces personnes font donc l’objet d’une double stigmatisation (stigmatisation liée au fait d’être âgé et d’être atteint de démence). Sur base de ce constat, cette présentation s’axera sur les liens qui peuvent exister entre nos représentations du vieillissement (et de la démence) et le concept de Qdv. Tout d’abord, nous aborderons les résultats des recherches dans le vieillissement « normal ». A côté des études de Levy (cf. Levy, 2009 pour une synthèse) ayant démontré l’impact délétère d’une vision négative du vieillissement sur la santé mentale et physique des aînés, diverses études récentes (ex : Bodner et al., 2011) ont montré qu’une vision négative du vieillissement était liée à une moindre Qdv. Plus encore, le niveau de Qdv peut en partie s’expliquer par la vision du vieillissement (ex : Top et al., 2012). Ces constations nous amènent à nous questionner sur la situation dans le cadre des pathologies démentielles. A ce niveau, il s’avère nécessaire de recourir à une hétéro-évaluation de la Qdv pour toute personne souffrant d’une démence sévère. En ce sens, ce n’est pas le patient lui-même qui fournit des réponses mais un aidant (professionnel ou familial). Sur base de cet élément, nous avons mis au point un protocole de recherche destiné à évaluer la Qdv de personnes souffrant de pathologies démentielles vivant en MR ou MRS, en y incluant des mesures d’âgisme des aidants. Ce protocole a été élaboré dans le cadre d’une collaboration avec l’ASBL Fédération des Institutions Hospitalières (FIH). Nous faisons l’hypothèse que la perception d’une même réalité (un même patient est évalué sur base d’un même outil) c.à.d. la qualité de vie, serait en partie tributaire de la vision que chaque soignant a du vieillissement et de la démence. Dans le prolongement de la présentation de cette étude, nous aborderons le fait qu’avoir une vision négative du vieillissement et de la démence nous amène à avoir des attitudes différentes (souvent bienveillantes mais pas toujours positives) à l’égard des personnes âgées. Ces attitudes ont un impact délétère sur la santé mentale et physique des personnes âgées et donc aussi sur leur qualité de vie (ex : Mandelblatt et al., 2003). Ces conséquences de l’âgisme sont donc susceptibles de confirmer la vision négative véhiculée à l’égard des personnes âgées (ex. : les personnes âgées sont vulnérables, dépendantes et ont une mauvaise qualité de vie) et ainsi d’alimenter un cercle vicieux.

The aim of this work was to measure the effect of supplementation with bovine colostrum among newborn Red goats breastfed in breeding conditions for semi-intensive type of Niger. The study was conducted in Secondary Goat Breeding Center of Maradi (SGBCM). Forty newborn kids, regardless of sexe, were divided randomly into two groups: a "T-Control " group receiving only breast milk per feeding (n = 20) and a "C-Colostrum" group having the same diet but supplemented with bovine colostrum thawed (50 ml the first day of life, then 25 ml in 2 meals/ day between the ages of 2 and 15d, n = 20). The results indicate that supplementation with bovine colostrum in the first 15 days of life, increases the growth of kids until weaning (P<0.001), modifie some barymetric changes some settings improves health status and reduces the mortality rate. To our knowledge, in the studied environment, this work is original and seems to bring new knowledges likely to have practical applications in areas with farming conditions quite difficult. [less ▲]

Two common approaches for beef aging are wet-aging and carcass-aging. Wet-aging refers to meat aged in a sealed vacuum package at refrigerated temperatures, while carcass aged at controlled temperatures and humidity is defined as carcass-aging. Carcass-aging is an ancient process used nowadays to produce beef characterized by its superior quality. The meat conservability is influenced by its sensitivity to oxidative process which can vary from one muscle to another. The aim of this study was to compare the effect of aging technique (wet-aging vs. carcass-aging), muscle (longissimus dorsi vs. rectus femoris) and previous vacuum storage time on colour and lipid stability of beef packaged in high-oxygen atmosphere. After a seven-day wet- or carcass-aging step, longissimus dorsi and rectus femoris muscle cuts from 4 Belgian Blue cows were vacuum packaged and stored at −1 °C for up to 28 days. At different times, part of these samples was repackaged under modified atmosphere – 70 % O2:30 % CO2 –, and stored during 7 days at +4 °C in order to simulate retail conditions. The following parameters were evaluated: colour (CIE L*a*b*), metmyoglobin %, lipid oxidation (TBARS), antioxidant enzyme activities (catalase, glutathione peroxidase and superoxide dismutase), alpha-tocopherol and fat content. The sensitivity of high-oxygen atmosphere repacked meat cuts to oxidation was influenced by the aging technique (wet > carcass conditions), muscle (rectus femoris > longissimus dorsi) and length of the vacuum storage. Oxidation stability could be associated with muscle catalase activity, and no association could be established with the alpha-tocopherol content. [less ▲]

Carnobacterium maltaromaticum is a lactic acid bacterium, and many lactic acid bacteria associated with meat are known for their bactericidal or bacteriostatic activity against other strains, species or genera of bacteria. The presence of certain lactic acid bacteria adapted to a low temperature in fresh meat could extend the shelf life and improve the microbial stability and safety of this product. The aim of this study was to perform a morphological and functional characterization of a C. maltaromaticum strain with a potential bioprotective effect isolated from vacuum packaged beef with very long shelf life. The morphological, biochemical and enzymatic profiles, the influence of different temperatures and atmospheres, and the microbial stability of fresh beef inoculated with the C. maltaromaticum strain were evaluated. The isolated C. maltaromaticum strain presented similar morphological, biochemical and enzymatic profiles as those of two reference strains (LMG 11393 and LMG 22902). Among the studied conditions, a temperature of +12 °C and an atmosphere poor in oxygen were optimal for the growth of C. maltaromaticum. Vacuum packing is therefore suitable for this bacterium. An antimicrobial effect against Enterobacteriaceae was highlighted on inoculated fresh meat stored under N2. The functional characterization of this isolate will be further pursued by a genotypic characterization. Special attention will be taken to study its bioprotective properties. [less ▲]

DBA/2J and C57BL/6J represent two opposite ends in terms of sensitivity and resistance to influenza A virus between the Mx-negative mouse lines. Several research teams focused on the factors explaining this difference, mainly by genetic approaches using Recombinant Inbred Lines between those two strains. Several candidate-genes have been proposed, but it was not possible to determine their importance. To help to define the factors involved in the susceptibility of DBA/2J mice to influenza infection, we adopted a phenotypic approach to identify the critical steps of the infection process accounting for this extreme susceptibility. Overall, the data presented here support the role of a dysfunction of alveolar macrophages, to influenza infection in the higher susceptibility of DBA/2J mice to this virus. [less ▲]

Eggs are a rich source of lipids and proteins. Because of their low production cost, they represent a cheap source of animal proteins and lipids. recently, in Algeria, consumers’ interest are oriented of healthiness and dietetic values food. The purpose of this study was to investigate the effects a dietary supplement of Urtica dioica on laying hen's performance and egg quality. The study was conducted from may to june 2014 in the area of Chemini (Algeria). Sixty, 25-wk-old Lohmann Brown layers were randomly divided into 3 groups with 20 hens in each group. Group 1 was the control group fed a standard commercial diet based on corn and soybean, whereas the groups 2 and 3 were fed the control diet supplemented with 1% and 1.5% of nettle respectively. The hens were housed in cages in the same local and fed ad libitum. Fifty five eggs were sampled 4 times in each group from 25 to 27 weeks. A total of 220 eggs were examined. A series of measurements were carried out on each egg, namely egg weight, form index (egg shape), yolk to albumen ratio (Y:A), Yolk color, egg shell thickness, Haugh’s units. Egg weight, yolk color and Haugh Units (HU) were affected by age. Significant differences (P<0.05) were recorded between feeding type in total egg weight, yolk color and Haugh Units. The egg from group 2 proved to have a higher egg weight (57.67g; group 1: 55.41g; group 3: 56.70g; P<0.05), (33.4%), intermediate Yolk color (8.53; group 1: 9.03 ; group 3: 9.38; P<0.05) and HU (79.81; group 1: 80.85; group 3: 76.92). The results showed that the use of 1% and 1.5% of Urtica dioica, had positive effects on the color of yolk of laying hens. Using different levels of Urtica dioica could change the characteristics of egg and could meet the preferences of consumers for the intense color of the yolk. [less ▲]

Bi2Sr2CaCu2O8+δ HTSC superconductor is characterized by a very strong normal-state resistivity anisotropy, with ρc/ρab typically above 104. The aim of this study is to use Quantitative Texture Analysis from neutron diffraction measurements to estimate the orientation effect on the macroscopic resistivity (ρM) in melt-cast bulk Bi2Sr2CaCu2O8+δ superconductors. Our approach uses the geometric mean (GMA) [1] of the single crystal resistivity tensor (ρSC) weighted by the Orientation Distribution Function (ODF) to quantitatively estimate the macroscopic resistivity tensor of the samples. The ODF is obtained from neutron Combined Analysis [2], using the E-WIMV algorithm of the MAUD software. The GMA applies to the rank-two resistivity tensor of the orthorhombic space group considered tetragonal due to the small difference of a- and b-axes of the phase, with only two independent tensor components. We relate a relatively good agreement between measured and calculated macroscopic resistivity ratios. [less ▲]

In 1865 the French mathematician Eugène Catalan was appointed professor at the University of Liege. In the nineteenth century the Belgian government developed a policy of attracting famous foreign scholars, mainly coming from the German principalities and France, in order to bring the education system to a higher level. In this case, however, the appointment had an outspoken political and philosophical dimension. Catalan sought and found refuge in Belgium because his career prospects in France were severely hindered due to his strong republican and anti-Bonapartist viewpoints. In a speech he gave at the University’s Academic Hall on the occasion of his retirement on December 7, 1881, Catalan emphasized he had two passions in life: la Politique militante et les Mathématiques [“Militant Politics and Mathematics”]. In this paper, we will investigate the first of these passions against the background of the revolutionary tensions of the time on the basis of a series of primary sources: first, a brochure edited by Catalan himself at the end of his life, entitled Miettes littéraires et politiques, par un vieux mathématicien (Liège, 1889); second, Catalan’s correspondence, covering several decades, and preserved at the Manuscripts Department of the University of Liège; third, a journal kept by Catalan during the years 1858 to 1862, entitled Journal d’un bourgeois de Paris. An in-depth analysis of these sources will allow us to discover Catalan’s own perception of his political and philosophical commitments, the reasons behind his involvement in the revolutionary uprisings of 1830, 1848 and 1851, the exact nature of his activism, his interpretation of the republican ideal, his political hopes and deceptions, his view on both French and European social and political realities, his struggle with the Catholic Church, the meaning of his engagement in Freemasonry.

Recent reports suggest that chlorophyll can also be used as a biomordant to enhance the dyeing process of textile products, but also as a textile dye with antimicrobial properties. In this presentation, different aspects of chlorophyll production are discussed. Firstly, numerous plant biomass types as potential sources of chlorophyll are presented. Subsequently, different methods for chlorophyll extraction and separation from plant biomass are described. Finally, possibilities of chlorophyll implementation into textile products on industrial scale are evaluated. [less ▲]

Objectif: Notre but est d'analyser la pression sous-glottique estimée (PSGE) en fonction de la pathologie vocale, du genre et du niveau de pression sonore. Nous observons également les corrélations entre la PSGE, le Voice Handicap Index (VHI) et le Dysphonia Severity Index (DSI). Méthode: 418 patients (118 H, 300 F) ont réalisé un bilan vocal (VLS, mesures acoustiques, aérodynamiques, VHI). La PSGE est collectée à l’aide du Phonatory Aerodynamic System Model 6600 (KayPentax). Les patients ont produit 3 séries de /ipipi/ à 3 niveaux de pressions sonores (conversationnel, faible et fort). Résultats: A intensité forte, les hommes ont un niveau de PSGE supérieur à celui des femmes. A intensité faible, le groupe « atrophie » montre des scores plus faibles que le groupe « nodules » et à intensité forte plus faibles que le groupe « polype ». A intensité conversationnelle, le groupe « examen normal » montre des scores plus faibles que les groupes « nodules », « polypes » et « œdème de Reinke ». A intensité faible, la même différence est observée avec en plus les groupes « kystes » et « cicatrices ». Nous observons une corrélation positive entre la PSGE et le VHI à intensité faible et négative à intensité forte. A intensité conversationnelle et faible, nous observons une corrélation négative entre le DSI et la PSGE. Quel que soit le niveau d’intensité, nous n’observons pas de corrélation pour le groupe « kyste ». Conclusion: Cette étude met en évidence l’intérêt de la PSGE. Une PSGE élevée est principalement observée chez les patients avec lésion sur le plan glottique. La corrélation entre PSGE et niveau de pression sonore varie en fonction de la pathologie. La mesure de PSGE peut aider le clinicien à mieux comprendre le comportement vocal du patient en lien avec sa pathologie. [less ▲]

Nous avons analysé les dossiers de 1079 patients (754 femmes et 325 hommes) qui se sont présentés au CHU de Liège entre 2009 et 2013 pour une plainte vocale. Chez ces patients, nous avons répertorié 121 personnes sans profession (11%), 166 étudiants (16%), 215 retraités (20%), et 577 travailleurs (53%). Parmi ces 577 travailleurs, il y avait notamment 129 enseignants, 55 employés de bureau, 50 chanteurs, comédiens et musiciens, 41 commerçants, 39 managers, 37 aides ménagères et 35 ouvriers. Objectif : Pour les travailleurs, nous avons tenté d’établir le degré d’exposition aux troubles de la voix selon la profession exercée en fonction de leur représentation dans la partie francophone de la Belgique (Wallonie). Notre objectif était de cibler les travailleurs les plus à risque de consulter un spécialiste de la voix. Méthode : Nous avons estimé la proportion de ces travailleurs par profession en calculant le rapport entre leur nombre en consultation phoniatrique et leur nombre parmi les travailleurs wallons. Résultats : Les travailleurs qui consultent le plus pour un problème de voix et qui sont donc le plus à risque sont, par ordre décroissant : les chanteurs, comédiens et musiciens (3.3% ont consulté), suivis par les professeurs de musique (1.5%), les animateurs (0.45%), les entraineurs sportifs (0.29%), les psychologues (0.20%), les journalistes et standardistes (0.17%), et les enseignants (0.14). En conclusion, cette étude montre que les travailleurs qui consultent le plus en phoniatrie ne représentent pas nécessairement le groupe professionnel le plus à risque. [less ▲]

At the beginning of Meditation IV the meditator triumphantly announces that he has “now no difficulty in turning away (convertam) from imaginable things and toward things which are objects of the intellect alone” (AT, VII, 53). Meditation VI thereafter confirms that pure intellection, as opposed to imagination, consists only in turning towards oneself (convertat) and demands no “peculiar effort of the mind” (73). However efforts of attention are required throughout the Meditations and Meditations IV, V and VI are no exceptions in this respect. Descartes’ Second Set of Replies (156-159) confirms that attention is needed as a mental support for metaphysical analysis in order to embrace different ideas and connect different parts of a demonstration. A thorough examination of the Meditations shows something even more interesting: attention is conceived by Descartes as a varying force that can be diminished or relaxed but also, and most importantly, increased as comparative forms like “attentius” (19; 55; 66; 71) or “diligentius” (32; 35; 45) suggest. For sure, it is an original aspect of Cartesian meditative exercise: we are not only invited to maintain our attention but also to make it more intense at a certain point. Such an increase is crucial for the development of the dream argument (55) and also for the achievement of both proofs of the existence of God (45; 66). But is it not a kind of deus ex machina that the meditator puts forward in order to overcome otherwise unsolvable difficulties? A posterior work, The Passions of the Soul, can help us understand such a strategy. In article 72, Descartes distinguishes between two kinds of attention; the first one stems from wonder and is “at its full strength from the start” (XI, 382); it is contrasted with a second type “which, being weak at first and growing only gradually, can be easily diverted” (Ibid.) Further on Descartes says that passion is useful in “strengthening thoughts… and causing them to endure into the soul” (383) but that “the application of our understanding” has the same effect when “our will fixes [it] in a particular attention or reflection” (384). This last case applies to the Meditations: the meditator who is constantly exposed to misleading influences would be easily “diverted” and even stopped if he was not pushed by his own will to go further in his metaphysical inquiry. “Peaks” of attention occurring in the Meditations are caused by volitions originating in the meditator’s resolution to attain truth and certainty and, as we shall see, they are used against three types of harmful influence: sensitive in Meditation I, imaginative in Meditation II and III, and intellectual in Meditation IV and V where old philosophical habits stand in the way of Cartesian theology.

In 2013, the Hungarian writer Terézia Mora was awarded the German Book Prize for her novel "Das Ungeheuer" (The Monster). Her text contrasts with other more current and popular novels in terms of thematic content, textual form, and book design. As such, "Das Ungeheuer" does not really fit into the range of "technically properly narrated" literature that used to be awarded with the prize. Usually, the laureates of the German Book Prize were so-called "Familienromane" (family novels), a currently very popular genre. By honouring Mora, the jury attempted to increase and preserve the prestige of the young literary prize (awarded since 2005) that is based on the model of the French Prix Goncourt and the English Booker Prize. The German Book Prize had quickly fallen into disrepute with the German literary critics who characterize the Book Prize as a "sheer marketing prize" because it comes along with high ranks in German bestseller lists and many foreign rights sales for its laureates. As a new award, the German Book Prize has to position itself in the literary field. A detailed analysis of the prize and its laureates therefore allows us to observe how the struggle for prestige develops today and to consider the question whether "attention" can be considered a new form of capital that competes with Bourdieu's symbolic capital, or a variant form of symbolic capital in the current media-drenched (literary) society. In order to find an answer to this question I am going to confront the marketing and transfer strategies as well as the literary reception of the novels "Die Mittagsfrau" by Julia Franck (laureate in 2007) and "Das Ungeheuer" by Terézia Mora.

IS THERE A ROLE FOR INTRA-ARTERIAL THERAPY OR ISOLATED LIVER PERFUSION? Pr Olivier Detry, Dpt of Abdominal Surgery and Transplantation, CHU Liege, University of Liege, The liver is the most common visceral site of colorectal cancer (CRC) metastasis and recurrence. Approximately 25% of CRC patients present with synchronous hepatic metastases at time of initial diagnosis, and further 50% will develop metachronous metastases during the course of their illness. Unfortunately, only 25% of patients with hepatic CRC metastases are suitable for R0 resection at time of diagnosis or after chemotherapy. Intra‐arterial locoregional therapies are evolving tools in the management of CRC liver metastases. Although these therapies were initially used for salvage and palliation, they are becoming therapeutic options earlier in the course of disease in selected populations, to increase the rate of curative surgical resection, and to improve survival and quality of life. Furthermore, intra‐arterial therapies may serve as viable first‐line treatments for the large majority of patients who present with unresectable liver metastases, and as neoadjuvant chemotherapy prior to hepatectomy to minimize systemic effects. Hyperthermic isolated liver perfusion (HILP) has also been proposed by some groups as a mean to treat patients with unresectable liver metastases. Significant anti-tumoral effect has been demonstrated but HILP is a complicated procedure with a high morbidity. There remains a lack of robust, prospective randomized data for fair and balanced comparisons to be made between locoregional and modern systemic therapeutic modalities, as well as between locoregional therapies. Future RCTs addressing overall patient survival, tumor response and toxicity are required before any of these locoregional intra‐arterial treatments can be definitively recommended as the standard of care for hepatic colorectal liver mestastases. At the CHU of Liege, intra-arterial chemotherapy is now the usual way of administrating chemotherapy in patients with multiple CRC metastases limited to the liver after R0 liver resection. [less ▲]

The purpose of this talk is to present recent advances and developments of the R package catR. This package allows for random generation of response patterns under computerized adaptive testing (CAT) and holds various options to select the first items, estimate ability, select the next item, stop the test and return final results. Two main improvements were realized. First, several rules for next item selection were added, among others, Kullback- Leibler, progressive and proportional methods. Second, catR was limited to dichotomous IRT models so far. The most recent update allows now for several polytomous IRT models, such as partial and generalized partial credit model, graded and modified graded response models, rating scale model, and nominal response model. All improvements will be shortly presented, both from a theoretical point of view and in terms of practical implementation in catR. If possible, several illustrative examples will be displayed in a short live demonstration of catR. [less ▲]

Introduction and objectives: In Crohn's disease (CD), there is a discrepancy between clinical activity of the disease (symptoms) and intestinal healing. However absence of tissue healing is associated with the risk of relapse and tissue damage progression. Endoscopy is costly and invasive. Hence biomarkers correlating with intestinal healing could improve disease management. We aimed to identify potential biomarkers associated to CD mucosal healing by a shotgun proteomics label free study. Methods: We used the STORI clinical trial cohort (n=103) aiming at identifying markers associated to relapse prediction after Infliximab treatment withdrawals. We used serum samples of patients in clinical remission, grouped according to the degree of intestinal healing seen at endoscopy. We performed depletion of the 20 most abundant plasma proteins on each serum pools and ran a proteomics label free differential analysis using 2D-nanoUPLC-MSE HDMS Synapt G1 for data acquisition and Protein Lynks Global Server vs 2.4 for data analysis (Waters, Corp., Milford, USA). Results and Discussion: We obtained potential biomarkers and designed a multiplexed -selected reaction monitoring (SRM) method for validation of these candidates in each individual patient. The method may also be tested in an independent set of IBD patients with and without mucosal healing. Conclusions: This research strategy and results of SRM validation of potential biomarkers associated to mucosal healing in this cohort of CD patients as well as the tests done on other CD patients, may provide new opportunities for CD follow-up tests development.

Near-Death Experiences (NDEs) are classically associated with positive emotions like peacefulness, happiness and joy [1-3]. To date, few negative NDEs reports have been documented [4]. Although NDEs classically arise in the context of an acute severe brain damage, their associated memories are reported as being phenomenologically very rich and detailed [5]. To date, no satisfactory explanatory model exits to fully account for the rich phenomenology of NDEs following a severe acute brain injury [6]. Neurobiological hypotheses include cerebral hypoxia [7, 8] and temporal lobe dysfunctions [9] to account for some of the features occurring during NDEs. However, it has been recently shown that anoxic/hypoxic, traumatic and other supratentorial brain lesions do not seem to influence the content of a NDE when assessed with a standardized tool (i.e., Greyson NDE scale; [1]). Due to their particular brain lesion (i.e., pontine brainstem), locked-in syndrome (LIS) patients provide a unique opportunity to further investigate the neural correlates of NDEs. We here aimed at retrospectively characterizing the content of NDEs in patients with LIS having suffered from an acute brainstem lesion (cerebrovascular accident (CVA) or trauma; i.e., “LIS NDEs”) and to compare these experiences to those collected in a cohort of matched NDE experiencers after coma with supratentorial lesions (CVA or trauma; i.e., “classical NDEs”).

Cyprinid herpesvirus 3 (CyHV-3) is the causative agent of a lethal disease in common and koi carp. Since its emergence, in the late 1990s, CyHV 3 has caused severe economic losses worldwide creating a need for a safe and efficacious vaccine. With this goal in mind, recombinant strains deleted for single gene were produced using prokaryotic recombination technologies. While producing such a recombinant for ORF134, we unexpectedly obtained a clone deleted for ORF56 and ORF57 in addition to the expected deletion of ORF134. Interestingly, this triple deleted recombinant replicated efficiently in vitro, exhibited an attenuated profile and induced an immune protection against a lethal challenge in vivo. To determine the role of each deleted locus in the phenotype of the triple deleted recombinant, a series of recombinant were produced and tested in vivo. Firstly, to investigate the role of ORF134 deletion, a double ORF56-57 deleted recombinant and an independent triple ORF56-57-ORF134 deleted recombinant were produced. These experiments revealed that ORF134 deletion did contribute significantly neither to the attenuation nor to the immune protection observed for the triple deleted recombinant. Secondly, to determine the relative importance of ORF56 and ORF57 deletion in the attenuation observed, two single deleted recombinants were produced for ORF56 and ORF57. These experiments demonstrated that ORF57 deletion, in contrast to ORF56 deletion, correlates with an attenuated phenotype. Based on its safety-efficacy profile, the ORF56-57 double deleted recombinant was selected as a candidate vaccine. Complementary experiments were performed to further investigate the potential of this strain as a safe and efficacious attenuated recombinant vaccine. The results obtained can be summarized as follows: (i) In vivo imaging (IVIS) of vaccinated fish challenged with a wild type strain expressing luciferase as a reporter gene, suggested that vaccination induces a sterile immunity at the portal of entry. (ii) Study of viral tropism by qPCR, IVIS, and histopathological analyses, demonstrated that in comparison to the wild type parental strain, the vaccine strain replicates at lower level, at later time post-infection and for a shorter period of time. (iii) Transmission studies demonstrated that there is no detectable spread of the vaccine from freshly vaccinated fish to naive fish located immediately down stream of vaccinated fish (water sharing). All together, the results of the present study demonstrate the potential of ORF56-ORF57 double deleted CyHV-3 recombinant strain for safe and efficacious mass vaccination of carp. [less ▲]

Background: Population based studies have shown evident benefit in terms of mortality from screening for Abdominal Aortic Aneurysm (AAA) among men aged over 65. However, recent studies from USA, UK and Sweden suggest a decrease in the prevalence of AAA in the general population. Whether these findings are generalizable for the rest of Europe is unknown. Thus we decided to set up a screening program in order to detect AAA in Liege, Belgium. Material and Methods: During our ongoing study, over a first 3-month period, abdominal aortic ultrasound was performed on 541 participants, (198 women 343 men) to measure the maximal suprarenal and infrarenal aortic outer-outer diameter as well as the maximal diameter of the common iliac arteries. Moreover, we have measured arm and ankle blood pressure in each subject and the clinical characteristics of the patients, were collected. Results: The overall AAA prevalence was 4.62% (n = 25). In female participants aged ≥ 74 years the AAA prevalence amounted 1.01 %. While in male patients aged ≥ 65 years, it rose to 6.71%. Statistical analysis showed that male gender, aging, history of ischemic heart diseases, hyperlipidemia and varicose veins were significantly associated with AAA. Conclusion: Despite a reported declining prevalence of AAA in some recent population-based studies, we found that the prevalence of AAA in Liège population remains high in men aged 65 years or more. The prevalence of AAA seems to vary in different geographical regions. However, we need a larger sample to confirm our preliminary findings. [less ▲]

Purpose: Successful downstaging of hepatocellular carcinoma (HCC) into the Milan criteria (MC) remains a controversial indication for orthotopic liver transplantation (OLT). In Belgium, successful downstaging of HCC is an accepted non-standard- ized exception (NSE) for liver allocation. This NSE group rep- resents a unique cohort to analyse if OLT can be safely offered to patients with those extended allocation criteria. The aim of this study is to compare the overall and recurrence free survival after cadaveric OLT between patients with successful downstaging (MILDOWN) and patients always inside the MC (MILIN) from all Belgian transplant centres. Methods: We ret- rospectively analysed all patients listed for OLT with HCC and underlying cirrhosis between 12/2006 and 12/2011 from all Belgian liver transplant centres. Successful downstaging was defined as bringing a patient who was outside the MC into the MC after locoregional therapy (LRT). Results: Overall 381 patients were listed in Belgium during the study period. Of these, 320 received OLT. 248 were MILIN, 62 were MIL- DOWN and 10 were transplanted outside MC. Downstaging treatment included transarterial chemoembolization (TACE; n=26), radiofrequency (RF; n=9), transarterial radioembolisa- tion (TARE; n=4), resection (n=3), percutaneous ethanol injec- tion (n=2) and a combination of the above-mentioned therapies in 18 cases. In the MILIN group 67.3% received locoregional therapy before transplantation, with no significant differences in the distribution of treatment type compared to the MIL- DOWN group. At listing there were no significant differences between the MILIN and MILDOWN group for age, gender and underlying liver disease. Median time on waiting list between the two groups was similar (120 days vs. 115.5 days). Overall survival at 1 year was not significantly different between MILIN and MILDOWN (87.1% vs. 79%; p=0.120). 1.6% of patients were lost to follow-up in both groups. Although not significant, recurrence free survival at 1 year tended to be higher in the MILIN group than in the MILDOWN group (83.9% vs. 74.2%; p=0.073). Conclusion: In this large Belgian multicentre cohort, overall and recurrence free survival at 1 year are not signifi- cantly different between patients who have been downstaged successfully and patients who were always inside the Milan criteria. However, a longer follow up period will define, if the trend of lower survival in the successfully downstaged group becomes significant. Factors associated with HCC recurrence have to be identified.

Background. Due to recently developed therapies, patients’ life expectancy with CF today is in the early 40s. As a result, medical providers in CF care centers seek not only to improve patients’ health but also to enhance their quality of life (QOL). QOL as a concept for children, in particular, is fairly new. Accordingly, QOL of school-aged children with CF is relatively under-investigated. In recent years, the role of family contextual variables has received increased attention as predictors of child adjustment to illness. Evidence exists that parenting and parent-child relationship factors are related to children’s emotional development and thus may be life-course determinants in their health. To date, no study has quantitatively investigated parental factors, particularly with respect to paternal variables, associated with the QOL of children with CF. Objective. The study aimed to investigate the relation of parenting stress, family functioning, and fathers’ involvement in the disease’s management to emotional distress and QOL in children with CF. Study design. Using a cross-sectional design, this study recruited families of children with CF from four different CF Centers. Data collection is on going and a full sample of 40 families is expected for this presentation. To date, the study protocol was completed by 18 families. Inclusion criteria for children include: (a) a diagnosis of CF for at least one year; and (b) age 8 to 12 years. Also, both parents must be willing to participate to be included in our sample. Children complete the State-Trait Anxiety Inventory for Children (STAIC), Children’s Depression Inventory (CDI-2), and Quality of Life Systemic Inventory for Children (QLSI-C). Parents complete the Parenting Stress Index – Short Form (PSI-4-SF), Family Environment Scale (FES), and Dad’s Active Disease Support (DADS) (i.e., a measure of paternal involvement in illness management). Results. With the full sample, we will run multiple regression analyses with STAIC, CDI, PSI-4-SF, FES and DADS as predictors of children’s QOL scores and run moderation and mediation analyses to examine the indirect effect of mothers and fathers’ variables on the child’s QOL. With the sample to date, QOL in children is significantly associated with state anxiety (r=.62; p=.007), trait anxiety (r=.76; p<.001), and depression (r=.77; p=.001). We also found a direct link between the mothers’ parenting stress levels and children’s QOL (r=.51; p=.031), anxiety (r=.49; p=.045), and depression (r=.47; p=.054). Fathers’ parenting stress levels (r=.54; p=.026) and mothers’ evaluation of fathers’ involvement (r=.47; p=.047) each are significantly associated with the mothers’ parenting stress. These results may be suggestive of a potential mediator effect. Conclusion. Information about fathers is underrepresented in pediatric psychology research. However, interest in impact of parental adaptation on children’s adjustment to chronic disease is on the increase. The results of this study are expected to contribute significantly to the understanding of how both parents play a role in the QOL and emotional adjustment of school-aged children with CF. [less ▲]

Several insect species are known to have different morphotypes, an adaptation to heterogeneities in changing environments. This phenotypic plasticity could be a factor used by the Multicoloured Asian Ladybird, which is considered as an invasive species in Europe since its introduction in the 80’s. Harmonia axyridis has four major morphotypes: 2 melanic forms, conspicua and spectabilis; and 2 non-melanic, succinea and axyridis. In Belgium, only the three first are observed. Literature reports variations in morphotype frequencies, across native and introduced strains. These variations seem to be linked to climate (geographical and seasonal variation), with non-melanic forms being the most abundant in hot and arid climate. This study focused on the variation of morphotype abundance in H. axyridis according to season, field and gender. Adult ladybirds were caught from mid-July to mid-October 2012 into 5 maize fields. The proportions of observed morphotypes were compared according to the sampling season. The abundance of morphotypes was not significantly different through the fields; the observed ratios were 81.6%, 15% and 3.4% for succinea, spectabilis and conspicua respectively. Succinea was the most observed morphotype (χ2=755.8; P<0.001). The total number of collected males and females was the same with ratios of 48.2% and 51.8%: (χ2=0.93; P=0.33). The sex ratio was also not significantly different for each morphotype. There was no evolution of melanic and non-melanic form ratio according to the season, with 25.6% of melanic form in summer and 20.6% in autumn (χ2=1.22; P=0.27). Our results seem to show that morphotype adaptation according to the climate is not observed for Belgian ladybirds. [less ▲]
