Variation at the pleiomorphic adenoma gene 1 (PLAG1) locus has recently been implicated in the regulation of stature and weight in Bos taurus. Using a population of 942 outbred Holstein-Friesian dairy calves, we report confirmation of this effect, demonstrating strong association of early life body weight with PLAG1 genotype. Peripubertal body weight and growth rate were also significantly associated with PLAG1 genotype. Growth rate per kilogram of body weight, daily feed intake, gross feed efficiency and residual feed intake were not significantly associated with PLAG1 genotype. This study supports the status of PLAG1 as a key regulator of mammalian growth. Further, the data indicate the utility of PLAG1 polymorphisms for the selection of animals to achieve enhanced weight gain or conversely to aid the selection of animals with lower mature body weight and thus lower maintenance energy requirements.

In a context of high productivity, eggs’ quality assessment is necessary for enhanced safety and quality assurance towards the consumers and feedback for producers. The quality assessment of eggs and egg products is performed using destructive and time-consuming methods, therefore the use of rapid tools becomes mandatory, especially in the case of a high production rate. Near Infrared (NIR) spectroscopy is considered a very reliable and rapid technique with large use in food industry. At the farm level, NIR spectroscopy technique would be an interesting tool to determine the chemical and physical properties of eggs, eggshell and internal quality and, moreover, this information may help the layer farm manager when a problem occurs in the flock. Its application in the egg industry is aimed at the quality changes in eggs during storage and quality assessment of the egg products, through the compositional analysis. It is possible and in some cases successful the prediction and/or determination of different parameters such as: protein, total lipid and total solids content (for liquid egg products), polyunsaturated fatty acids (for freeze-dried egg yolk), moisture, fat and protein content (for spray-dried whole eggs). In addition, for the white colored shell eggs, the detection of blood and meat spots is also successful. Further studies with NIR and near infrared hyper spectral imaging system (NIR-HSI) are needed in this direction, as the results obtained until now are very promising for the development of a rapid tool for quality assessment of eggs and egg products.

Introduction : Le plasma riche en plaquettes (PRP) aurait des effets bénéfiques sur les symptômes des tendinopathies grâce à la libération locale de leurs nombreux facteurs de croissance. Le but de cette étude est d’évaluer les résultats d’une injection de PRP sur la symptomatologie des patients présentant une tendinopathie patellaire supérieure. Matériels et Méthodes : Vingt patients atteints d’une tendinopathie patellaire supérieure, rebelle aux traitements conservateurs classiques depuis au moins 3 mois, ont bénéficié d’une évaluation du statut algo-fonctionnel (EVA, algomètre de pression, VISA-P et IKDC) et des performances physqiues (isocinétique et optojump), ainsi que d’un bilan d’imagerie (échographie et IRM). Ces analyses ont été réalisées en pré-injection ainsi qu’aux 6èmeet 12èmesemaines post-injection. Le test isocinétique évaluait la force des quadriceps et des ischios-jambiers des deux membres suivant différentes modalités (C60°/sec, C240°/sec et E30°/sec). Le test Optojump évaluait la détente et la puissance musculaire par la mesure de la hauteur de saut via deux modalités («Counter Movement Jump » et « Drop Jump »). Le PRP est obtenue à l’aide d’une machine d’aphérèse (COM.TEC, Fresenius-Kabi), permettant d’obtenir une concentration plaquettaire reproductible d’un patient à l’autre, en l’absence quasi totale de globules rouges et blancs. L’infiltration intratendineuse de PRP (6mL) est réalisé à la pointe de la rotule in loco dolenti sans anesthésie locale. Résultats : Les résultats de notre expérimentation démontrent qu’une seule injection locale de PRP accompagnée d’un programme de rééducation excentrique améliore significativement la cicatrisation du tendon patellaire au niveau du score EVA, de l’algomètre de pression, des scores VISA-P et IKDC. Lors du test isocinétique, seuls l’augmentation du MFM des ischios jambiers en C240°/sec, de la différence bilatérale des ischios jambiers en C60°/sec ainsi que de l’EVA en E30°/sec était significative. Les résultats optojump en terme de détente et puissance musculaire ne montrent pas d’amélioration des performances. Néanmoins, l’EVA du « Counter Movement Jump » se voit significativement diminuée après l’infiltration. Enfin, les résultats de l’imagerie (échographie et IRM) ne démontrent pas de modification significative du tendon. Conclusions : L’injection locale de PRP dans le cadre de tendinopathies patellaires supérieure permet une diminution de la symptomatologie douloureuse à 6 semaines, se poursuivant à 12 semaines. La performance fonctionnelle et l’imageries, quant à elles, ne sont pas modifiées. [less ▲]

The present article aims at pinpointing the issues involved in the analysis of the economy of ‘primitive’ societies carried out by Deleuze and Guattari in Anti-Oedipus by relying on a logic of debt (Nietzsche) rather than on a logic of reciprocity (Lévi-Strauss). Deleuze and Guattari’s critical discussion of Lévi-Strauss’s ethnology should related to the problematization of kinship as a system of alliance and filiation relationships suggested by French Marxist anthropology (E. Terray, C. Meillassoux) on the one hand, and to Edmund Leach’s critical anthropology on the other. This double mediation helps to show that in Anti-Oedipus, Deleuze and Guattari seek to identify the political strategies which are at work in economic relationships, that is to say, in the present case, the finite alliance strategies in ‘primitive’ societies, which are deeper than trade and production relationships.

The aim of this analysis was to determine whether pregnancy loss (PL) after embryo transfer (ET) in cattle was related to maternal progesterone (P4) concentrations during and shortly after ET, and maternal bovine pregnancy-associated glycoprotein-1 (bPAG-1) concentrations in plasma at days 25–35 of gestation. Embryos (n = 260) were produced either in vivo after superovulation (n = 115), or in vitro from oocytes (obtained with ovum pick-up) in co-culture (n = 44) or cultured in a synthetic medium (n = 101). Overall, PL was 56.9% (148) and no significant differences occurred in calving rate among the three embryo production groups. There was no difference in P4 concentrations on days 7–14 of gestation in the three groups, nor between ongoing and interrupted pregnancies. Between days 25 and 35 of pregnancy, bPAG-1 concentrations were unaffected by embryo production, but in cattle that had PL between days 26 and 120, four bPAG-1 profiles could be detected. Between days 25 and 32, bPAG-1 concentrations were influenced by PL, and concentrations were significantly lower in animals in which PL occurred between days 26 and 120 than in those animals that aborted later or calved at term. Early P4 concentrations suggested that maternal luteal factors were not responsible for PL which appeared to be caused by impaired conceptus development (regardless of embryo type) as reflected by low maternal bPAG-1 concentrations prior to embryonic death [less ▲]

Background Studies in population genetics are mainly based on the analysis of genetic variations among different populations. With the advent of advanced genotyping technology, large number of Single Nucleotide Polymorphisms (SNPs) can be used to capture the underlying population variations. Iterative pruning principal component analysis (ipPCA) is a very powerful tool to cluster subpopulations based on their SNP profiles. However, when several similar populations are considered in the analysis, differentiating these populations can become very challenging. Haplotype has been known to capture more segregation information and higher power than SNP but due to high inference complexity, this concept has not been widely used. Recently, haplotype sharing (HS) was reported as a good alternative method to evaluate variation among populations. HS interrogates the entire genotyping without estimating haplotype block, making it computational efficient, yet retaining population profile. Adopting HS technique and introducing a new haplotype encoding as the input to ipPCA to perform population clustering can yield very good outcomes. Results In this study we transformed an indigenous Thai SNP genotyping data, obtained from Pan Asian SNP consortium, into encoded haplotype profiles. The dataset include 13 indigenous populations (245 individuals) composing of approximately 54K SNPs for each individual. To do this, an encoded haplotype matrix was constructed by inferring overlapping haplotype based on sliding window approach in BEAGLE, an efficient haplotype inference tool. We fed this encoded haplotype matrix to ipPCA to cluster these individuals into sub-groups using only their genetic profiles. We compared the results obtained from standard protocol of ipPCA with the one that use the encoded haplotype matrix in terms of numbers of clustered subpopulations as well as the accuracy to correctly assign an individual to a correct subpopulation. Using the encoded haplotype matrix as input to ipPCA rendered the exact 13 subpopulations to be clustered with 99.18% of individual assignment accuracy, whereas the conventional ipPCA identified only 10 subpopulations with 93.47% of individual assignment accuracy. Conclusions Our result demonstrated the great potential of using the encoded haplotype matrix with ipPCA for population genetics studies. This new protocol can promote the clustering of individuals using only their genetic profiles. [less ▲]

Objectif : Etudier l’expression de KISS1 (métastatine) et de son récepteur KISS1R lors de la grossesse normale et pathologique. Matériels et méthodes : Nous avons étudié la localisation de KISS1 et KISS1R par immunohistochimie dans des placentas normaux (1 er et 3 ème trimestre). Par RT-PCR quantitative, nous avons évalué le niveau d’expression des ARNm dans les placentas et les lits placentaires correspondants. Les niveaux d’expression de ARNm ont été comparés entre les grossesses normales (GN, n=13) et les grossesses spathologiques Prééclampsiques -PE-, n=17 et retard de croissance intrautérine -RCIU-, n=9). Résultats : Au premier trimestre des GN, KISS1 est majoritairement localisé dans les syncitiotrophoblastes, alors que KISS1R est détecté dans le mesenchyme villositaire. Au cours du troisième trimestre, KISS1 est uniquement localisé dans le syncitiotrophoblaste au contact avec la décidue et dans le mésenchyme villositaire et KISS1R est détecté dans le trophoblaste extra-villeux ainsi que dans quelques cellules de la décidue. Les analyses par RT-PCR mettent en évidence une expression plus importante des ARNm de KISS1 (p<0,001) et de KISS1R (p=0.039) dans les placentas (GN,PE et RCIU) par rapport aux lits placentaires correspondants. Les niveaux d’expression de KISS1 et KISS1R ne sont pas, cependant, significativement modulés dans les grossesses pathologiques. Conclusions : Par immunohistochimie, nos résultats indiquent une expression spatiotemporelle différente pour KISS1 et KISS1R entre le 1 er et 3 ème trimestre des grossesses normales. Nous n’avons pas mis en évidence de modulation de l’expression des ARNm dans les grossesses pathologiques. [less ▲]

The 21st century is rich in mutations regarding veterinary medicine; society has never been so far from farm animal practices in industrialized countries, and so demanding in developing nations for a continuous milk and meat production. Meanwhile, even this great distance in northern nations between agriculture and society, our work has never been so much analyzed for its potential risk on human health and production quality. As health is now globalized, following trade and science, exchange could be the source of several pathological emergences. Focusing on animal health, our responsibility toward “larga manu” use of antibiotics has been identified and criticized. This situation is also happening in a time where, nevertheless our industrialization of agricultural production, ancillary exams are still expensive, and most of the time non valuable regarding a common cattle practice time schedule. So yes, we are mainly still experiencing empirical use of antibiotics like our pairs did, back several decades before. Yet, there exists nowadays many tools to analyze whether our practice could be considered as harmful to humanity survival and good use of priority antibiotics. We therefore have to reconsider our practice of Antibiotherapy, regarding these new challenges and find new ways for medical management of infectious diseases. [less ▲]

In the wake of Richards Benton’s “Keats and Zen” (published in Philosophy East and West (1966)), this paper sets out to examine Janet Frame’s appropriation of Buddhist philosophy in Snowman, Snowman (1962). The novella’s allusions to a Buddhist-like epistemology, together with its subtle references to Scandinavian myths, however, have so far remained uncovered and are therefore best approached in the light of what has been called “the suppressed intertextuality in post-colonial writing”. The author’s intention in this paper is twofold: On the one hand, the author will suggest that post-colonial writers do not necessarily write against the Western canon and that maintaining the contrary amounts to vindicating the centrality of imperial texts in the contemporary literary scene—an endeavour which is hardly post-colonial. On the other hand, the author will go some way towards shifting eastward the core of Frame’s ontology by suggesting that her poetics is anchored not only in Western thinking, but also, perhaps more importantly so, in Eastern philosophy. The author’s primary impulse, however, in examining the interplay between canonical and peripheral intertextualities, is to illuminate in fundamental fashion the haunting beauty of the writer’s universe and the lyricism of Snowman, Snowman.

Bone marrow stromal cells are adult multipotent cells that represent an attractive tool in cellular therapy strategies. Several studies have reported that in vitro passaging of mesenchymal stem cells alters the functional and biological properties of those cells, leading to the accumulation of genetic aberrations. Recent studies described bone marrow stromal cells (BMSC) as mixed populations of cells including mesenchymal (MSC) and neural crest stem cells (NCSC). Here, we report the transformation of NCSC into tumorigenic cells, after in vitro long-term passaging. Indeed, the characterization of 6 neural crest-derived clones revealed the presence of one tumorigenic clone. Transcriptomic analyses of this clone highlighted, among others, numerous cell cycle checkpoint modifications and chromosome 11q down-regulation (suggesting a deletion of chromosome 11q) compared with the other clones. Moreover, unsupervised analysis such as a dendrogram generated after agglomerative hierarchical clustering comparing several transcriptomic data showed important similarities between the tumorigenic neural crest-derived clone and mammary tumor cell lines. Altogether, it appeared that NCSC isolated from adult bone marrow represents a potential danger for cellular therapy, and consequently, we recommend that phenotypic, functional and genetic assays should be performed on bone marrow mesenchymal and neural crest stem cells before in vivo use, to demonstrate whether their biological properties, after ex vivo expansion, remain suitable for clinical application.
