Intérêt de l'apport de levures sur la susceptibilité à l'acidose et le comportement alimentaire du ruminant (application à la chèvre laitière)

L’acidose sub-clinique est relativement difficile a diagnostiquer et a prevenir en elevage, car elle est principalement caracterisee par une instabilite des fermentations ruminales et des parametres zootechniques. Une meta-analyse, realisee sur 110 publications, a montre que les levures pouvaient reguler les fermentations ruminales, en particulier pour les animaux a fort niveau d’ingestion et recevant un regime riche en concentre. La distribution d’un regime riche en concentre a entraine une situation d’acidose subclinique (pH < 6,25) entrecoupee par des crises spontanees d’acidose, plus ou moins nombreuses selon les individus, et pouvant influencer la production pendant plusieurs semaines. Les mesures quotidiennes d’ingestion, de production et de pH ruminal ont permis de modeliser la dynamique d’evolution de ces trois parametres pendant les crises d’acidose, ce qui constitue une premiere approche vers un modele plus mecaniste de l’acidose. De nombreuses mises au point methodologiques ont ete effectuees afin de mesurer simultanement l’ingestion, le pH ruminal et la mastication en continu (pas de temps de l’ordre de la minute) pendant plusieurs semaines. Ces mesures ont permis de presenter une nouvelle methode d’analyse de l’ingestion par segmentation / classification et de determiner des types de comportements alimentaires differents, independants du regime distribue et plus ou moins stables selon les individus, les crises d’acidose etant caracterisees par un manque d’appetit et une desorganisation de l’ingestion et de la rumination. Ces types de comportements sont associes, pour des quantites ingerees similaires, a des cinetiques de pH tres differentes. Cependant, aucune relation n’a ete mise en evidence entre le type de comportement alimentaire individuel, et la susceptibilite individuelle des animaux a l’acidose. La prise en compte des episodes d’acidose dans les analyses a permis d’eviter les confusions d’effets. L’apport de levures a augmente la production laitiere, sans modifier la matiere seche ingeree, la production de matiere grasse ou de proteines du lait. Ceci pourrait resulter de l’augmentation de la proportion de concentre ingeree par les animaux supplementes, suite a un tri en faveur d’une ration moins fibreuse que celle ingeree par les temoins. La supplementation a egalement eu tendance a augmenter la biodiversite de l’ecosysteme ruminal, ce qui pourrait expliquer que la diminution du pourcentage de fibres ingerees n’a pas induit de baisse du pH ruminal. Cette etude a montre que les crises d’acidose spontanees ont eu des consequences importantes sur tous les parametres etudies, et souligne l’interet de la prise en compte du comportement alimentaire pour mieux comprendre les phenomenes digestifs et metaboliques.
Food Recommendation System Using Sequential Pattern Mining

Sequential pattern mining is an important subfield in data mining. In this paper, we introduce a sequential pattern mining-based food recommendation system. The purchase history of users is analyzed to find their sequential patterns using SPADE algorithm [5]. These patterns are then used to predict the next possible purchase. One of these patterns will be shown as a special offer with discount. The proposed approach is experimented on real transaction data. It demonstrate that the proposed system effectively improves the efficiency for mining sequential patterns, increases the user-relevance of the identified sequential patterns, and most importantly, generates significantly more accurate next-items recommendation for the target users.
Beyond Neuroanatomy: Novel Approaches to Studying Brain Evolution

The study of the evolution of brain structure and function, although fascinating, has been contentious, largely due to the correlative nature of neuroanatomical comparisons and the often ill-defined categorizations of habitat and behavior. We outline four conceptual approaches that will help the field of brain evolution emerge from a historical focus on descriptive comparative neuroanatomy. First, reliable, efficient and unbiased behavioral assays must be developed to characterize relevant cross-species differences in addition to focused studies of neuroanatomy. Second, developmental and physiological processes underlying neuroanatomical and behavioral differences can be analyzed using the comparative approach. Third, genome-wide comparisons including genome-wide linkage mapping, transcriptional profiling, and direct sequence comparisons, can be applied to identify the genetic basis for phenotypic differences. Finally, signatures of selection in DNA sequence can provide clues about adaptive genetic changes that affect the nervous system. These four approaches, which all depend on well-resolved phylogenies, will build on detailed neuroanatomical studies to provide a richer understanding of mechanistic and selective factors underlying brain evolution.
Influence of platelet count and activity on thromboelastography parameters

It has been suggested that thromboelastography (TEG) can help in limiting or directing the appropriate use of blood products during surgery. However, the contribution of platelets to the TEG profile has not been studied in detail. Blood was taken from eight healthy subjects and eight patients with peripheral arterial disease (PAD). Immunomagnetic separation was achieved by the addition of Dynabeads® labeled with a CD41 murine antibody (to the GPIIb/IIIa receptor) to achieve 90-100% depletion of platelets from blood. This was then titrated with whole blood to achieve platelet counts of approximately 0, 25 and 50% of the original count to compare with whole blood using TEG. Platelet function was also assessed by spontaneous platelet aggregometry (SPA) at baseline and at the 50% dilution. SPA, maximum amplitude (MA) and K time were significantly different in PAD patients compared to controls (P < 0.05). In both controls and PAD patients there was a strong linear correlation between Log10 [platelet count] and MA (r=0.97 for controls, r=0.89 for PAD) and K time (r=−0.86 for controls, r=−0.68 for PAD). Correlation between Log10 [platelet count] and R time was poor in both groups. The MA and K TEG parameters may be most useful for assessing platelet transfusion requirements.
De la reterritorialisation à la relocalisation des filières, avec ou sans terroir

Les fonctions hydrologiques, biogeochimiques et biologiques des zones humides sont souvent mises en avant dans les politiques publiques de preservation des milieux naturels. Face a ce constat, les schemas directeurs d’amenagement et de gestion des eaux demandent desormais la compensation des fonctions des zones humides en cas d’impact sur ces milieux par des amenagements. Afin de repondre a cette demande, une methode d’evaluation rapide des fonctions des zones humides a ete developpee. Cet article presente la demarche de validation de la methode dans les Alpes du Nord, ou sa reproductibilite a ete etudiee et ses resultats compares avec des donnees plus approfondies issues du programme rhonalpin de suivi des zones humides.
Autonomous Dirigible Navigation Using Visual Tracking and Pose Estimation

Describes a methodology for visual navigation of dirigibles based on tracking and pose estimation of visual beacons-artificial landmarks with known geometrical and visual properties. Fast pose estimation for the dirigible is necessary since the 3D position and orientation data may be used for attitude control. Robust tracking of the beacons is also an important feature. The methodology is validated through different experiments. Results on precision of position and velocity parameters, robustness in tracking the beacon in unstructured environments and time performance of the system are discussed. Finally, future improvements and applications to external airships are discussed.
Immunoregulatory function of mesenchymal stem cells

Mesenchymal stem cells (MSC) are a rare subset of stem cells residing in the bone marrow where they closely interact with hematopoietic stem cells and support their growth and differentiation. MSC can differentiate into multiple mesenchymal and non‐mesenchymal lineages, providing a promising tool for tissue repair. In addition, MSC suppress many T cell, B cell and NK cell functions and may affect also dendritic cell activities. Due to their limited immunogenicity, MSC are poorly recognized by HLA‐incompatible hosts. Based on these unique properties, MSC are currently under investigation for their possible use to treat immuno‐mediated diseases. However, both their condition of immunoprivilege and their immunosuppressive function have recently been challenged when analyzed under particular experimental conditions. Thus, it is likely that MSC effects on the immune system may be deeply influenced not only by cell‐to‐cell interactions, but also by environmental factors shaping their phenotype and functions.
Multiple Venous Malformations with Phleboliths: Radiological-Pathological Correlation

Vascular malformations are congenital lesions that are present at birth and do not regress. However, they often present later in life. They are subdivided into two categories: (1) slow- or low-flow and (2) fast- or high-flow malformations. Low-flow malformations contain combinations of capillary, venous, and lymphatic components. Venous malformations can occur anywhere in the body, but are most frequently seen in the head and neck (40%). These lesions present in a variety of ways, from a vague blue patch to a soft blue mass, which may be single isolated or may occur in multiple areas. Treatment depends on the type of lesion, the location, degree of involvement, and the clinical symptoms. Here we are report the imaging and histopathologic findings in a patient with multiple venous malformations affecting the left side of the face and trunk.
What drives the positive correlation between human population density and bird species richness in Australia

Aim To test six hypotheses that could explain or mediate the positive correlation between human population density (HPD) and bird species richness while controlling for biased sampling effort. These hypotheses were labelled as follows: productivity (net primary productivity, NPP); inherent heterogeneity (diversity of vegetation types); anthropogenic heterogeneity (diversity of land uses); conservation policy (proportion of conservation land); increased productivity (humaninduced productivity increases); and the reduced-slope hypothesis (which predicts that humans have a negative impact on species numbers across the full range of variation in HPD).
End-of-life conversations: evolving practice and theory.

This article examines the evolution of and need for "end-of-life conversations. " Barriers to end-of-life discussions that have been identified in patients and families, health care professionals, and health care systems can seriously interfere with the quality of remaining life for terminally ill patients. Strategies for enhancing end-of-life discussions are most productively linked to (1) physicians' interpersonal communication skills, (2) a patient-centered model of care, (3) a focus on quality of remaining life, and (4) innovative clinical models for implementing these discussions earlier in the care process. We conclude that end-of-life conversations must become a routine, structured intervention in health care and that advance care planning is best viewed as one component in a series of ongoing end-of-life discussions. Randomized trials are needed to examine new approaches and models for enhancing end-of-life conversations. JAMA. 2000;284:1573-1578.
Evaluating performance on older individuals using a fMRI protocol for Wisconsin Card Sorting Task

This paper describes an fMRI study with 76 middle-aged and older subjects using the Wisconsin Card Sorting Task, widely utilized to investigate executive function and frontal lobe dysfunction. Several cognitive processes involved in the task are correlated with the cognitive decline observed due to aging. With functional imaging we demonstrate that subjects with a better performance show an increased activation in the frontal lobe and cingulate cortex, which are important regions for the processes involved in the task.
Building mPHR to assist diabetics in self-healthcare management

There are more than 220 million diabetics in the world and 5 % of global deaths was resulted from diabetes or diabetes complications. The cost of diabetes of medical and healthcare is very high at each state. Diabetics can be controlled through proper self-care behaviors, risk of the complications like the disease of eyes; kidney; nerve and cardiovascular system can be deduced through positively blood sugar control and healthcare. PHR is a tool that can help diabetics to manage their diabetes self-care. The form of PHR was changed from paper chart to ePHR. Most of ePHR provides service for users to save and upload their own health records through the Internet and to access data by using computer. But the mobility of a computer is not so convenient and probably set on an immovable place. There are more people using mobile devices to communicate with others and get information through the mobile Internet. This study will build a mPHR system for diabetics and diabetics can use mobile phone upload their own health records and access their data from the Internet Questionnaires are being utilized as a measurement for the acceptance of mPHR system and the difference in self-care behaviors between diabetics using mPHR system before and after.
A Compact Model of Silicon-Based Nanowire MOSFETs for Circuit Simulation and Design

A silicon-based nanowire FET (SNWT) compact model is developed for circuit simulation. Starting from the solution of poisson's equation, an accurate inversion charge expression is derived for SNWTs with arbitrary body doping concentration. The drain current, transconductance, output conductance, terminal charges, and capacitances are then calculated based on fundamental device physics. Short-channel and quantum effects have been included in the model in a self-consistent way. Comparison between the numerical simulation and analytical calculation shows that the proposed model is valid for all operation regions of SNWTs with different dimensions and channel doping. The model has been implemented in circuit simulators by Verilog-A, and its application in circuit simulation is also demonstrated.
Representations With Constant System Matrices of Linear Time-Periodic Dynamical Systems

Abstract In the paper it is investigated, under which conditions a time variable state transformation can be used to change a periodic autonomous system realization into a form with constant real coefficients. Conditions for the transformation to be periodic are further considered, and it is shown that the necessary and sufficient condition to meet the conditions is in that two specific matrices must be similar to each other. The properties of the matrices and the transformation are studied, and the discussion is then extended to input-output systems. An approach to design stabilizing control laws for these kinds of periodic systems is outlined.
Growth and Bone Mineral Accretion During Puberty in Chinese Girls: A Five‐Year Longitudinal Study

There are few longitudinal data on bone development during puberty in children with low calcium intake. This 5‐yr longitudinal study showed that, in Chinese girls, the mean apparent calcium retention efficiency during puberty was 40.9%, PHV occurred at 3–0 yr before menarche, and peak bone mineral accretion occurred 1 yr later than PHV. Chinese girls have high calcium retention efficiency during puberty.
Music and the Continuous Nature of the Mind : Koelsch ’ s ( 2012 ) Brain and Music Reviewed

Anyone interested in the neuroscience of music will likely be familiar with the work of Stefan Koelsch, who since 2010 is Professor of Biological Psychology and Music Psychology at the Freie Universität Berlin. His book Brain and Music (2012) is a useful synthesis of his rigorous empirical work and theoretical contributions on the psychology and neuroscience of music, which have included some 75 co-authored articles during the past 15 years. In this review, I shall first provide a sketch of the book’s contents, including examples of Koelsch’s empirical work from four core areas: (1) musical syntax, (2) musical semantics, (3) music and action, and (4) music and emotion, before providing a few thoughts in response to this impressive work. The first seven chapters of the book, drawn from Koelsch’s dissertation, provide useful reviews on the foundational topics of ear and hearing (Chapter 1), music theory (Chapter 2), the perception of pitch and harmony (Chapter 3), EEG and MEG (Chapter 4), event-related potentials (ERPs), including a review of language ERP research (Chapter 5), a review of music ERP research (Chapter 6), and functional neuroimaging (Chapter 7). Researchers using the ERP technique to study language or music will find the review and synthesis presented in Chapters 5 and 6 invaluable. The remaining chapters cover material that will likely already be familiar to the seasoned readers of this journal, but highly useful for students needing additional background in one or more of these foundational disciplines. The essential chapters comprising the second half of the book give an overview of Koelsch’s framework (Chapter 8), followed by integrative reviews of work on musical syntax (Chapter 9), musical semantics (Chapter 10), music and action (Chapter 11), and emotion (Chapter 12), followed by an overall summary of the theory (Chapter 13).
Design of a power assist system for lifting objects based on human's weight perception and changes in system's time constant

In this paper, we designed a simple 1 DOF power assist system for lifting objects based on human's perception of object weight. We hypothesized that, human's perception of weight due to inertial force might be different from the perceived weight due to gravitational force. We then compared human's load force rates for lifting objects manually with that for lifting objects with the power assist system. We found the load force rates much lower for the power assisted objects. We then hypothesized whether or not mechanical time constant of the power assist system is a factor that reduces heaviness of objects lifted with it. The results show that, higher mechanical time constant lowers the perceived heaviness as well as peak load forces. Uses of the findings in design of power assist robots for lifting heavy objects in industries may improve interactions with humans.
Intra-arterial therapy for basilar artery thrombosis: the role of machine learning in outcome prediction

INTRODUCTION: Although only 10% of strokes are due to involvement of the posterior circulation, they can be associated with a very poor prognosis. Therefore, accurately predicting stroke outcome from a set of variables may identify high-risk patients and guide treatment approaches, leading to decreased morbidity. In this study, our aim was to design and compare different machine learning methods, capable of predicting the outcome of endovascular intervention in acute posterior circulation ischaemic stroke. METHODS: We conducted a retrospective analysis of a prospectively collected database of acute posterior circulation ischaemic stroke treated by endovascular intervention. Using SPSS®, MATLAB® and Rapidminer®, classical statistics as well as artificial neural network and support vector algorithms were applied to design a supervised machine capable of classifying these predictors into potential good and poor outcomes, as defined by 30 day mRS. RESULTS: We included 50 consecutive acute posterior circulation ischaemic stroke patients treated by endovascular technique. All the available demographic, procedural and clinical factors were included in the machine. The final confusion matrix of the neural network, demonstrated an overall congruency of ~90% between the target and output classes, with a relatively favourable overall receiving operative characteristic. However, after optimisation, the support vector machine had a relatively better performance, with a root mean squared error of 2.432 (SD: ±0.584). CONCLUSION: Consistent with the findings for anterior circulation, we showed promising accuracy of outcome prediction in posterior circulation strokes, suggesting that a robust machine learning system can potentially help in prognostication of acute posterior circulation stroke.Keywords: stroke, cerebrovascular occlusion, brain infarction - posterior circulation, brain infarction ‐ anterior circulation, predictors.
Field genetic evaluation of beef cattle in France: From birth to slaughterhouse

The "BLUP Animal Model" methodology was put forward in 1991 to improve the French genetic evaluation of suckling breeding stock by using on-farm performance recording from birth to weaning. Based on this methodology, the IBOVAL evaluation has officially replaced the former evaluations since 1994. Today, nine breeds are concerned: either beef production specialised breeds (Bazadaise, Blonde d'Aquitaine, Charolaise, Limousine), or hardy breeds adapted to inhospitable environments (Aubrac, Gasconne, Salers) as well as dual purpose suckling breeds (Rouge des Pres formerly known as Maine-Anjou, Parthenaise). Beside French animals, performances from Italy (Limousine and Charolaise), Luxemburg (Limousine and Charolaise), Spain (Blonde d'Aquitaine) and The Netherland (Charolaise). have also been included in the IBOVAL evaluation. Performances in these countries for the detailed breeds are recorded following the French methods and are considered as French performances.
Priming Effects in Amnesia and Normal Memory

Learning and memory are inextricably intertwined. The capacity for learning presupposes an ability to retain the knowledge acquired through experience, while memory stores the background knowledge against which new learning takes place. During the dark years of radical behaviorism, when the concept of memory was deemed too mentalistic to be a proper subject of scientific study, research on human memory took the form of research on verbal learning (Schwartz & Reisberg 1991; Anderson 2000).
Acute Dacryocystitis with Empyema of the Lacrimal Sac

Objectives To evaluate the efficacy of endoscopic dacryocystorhinostomy (Endo-DCR) in the treatment of acute dacryocystitis with lacrimal sac empyema (ADLSE). Design Case series with chart review. Setting Academic tertiary center. Patients The study included 26 consecutive patients who underwent Endo-DCR for ADLSE between August 2005 and December 2013. Main Outcome Measures The success of the procedure was defined as complete complaint relief and DCR patency. Data on the time from referral to surgery, postoperative complications, and revision surgery are also reported. Results The present patient series included 4 males (15.4%) and 22 females (84.6%) (mean age, 66 years). The mean time between referral and surgery was 0.88 days and the mean follow-up time was 29 months. All patients showed immediate relief from symptoms, with no ADLSE recurrences. Complete success was achieved in 25 (96.2%) cases; the only failure was in a patient who had previously undergone radioiodine treatment. In this case, revision Endo-DCR was not successful. The only perioperative complication (3.8%) was epistaxis in a patient who required revision surgery under general anesthesia. The definitive success rate was 96.2% after primary and revision surgery. Conclusions Endo-DCR enables rapid resolution of ADLSE with a very high success rate. Immediate surgery may reduce the risk of skin fistulization and/or orbital complications. DCR shrinkage and lacrimal obstruction are unlikely with Endo-DCR since the procedure is performed on an enlarged sac. The main advantage of Endo-DCR, compared with external DCR, is the absence of a skin incision in an inflamed and infected field.
