Abstract: foodborne diseases have been deserving special attention by researchers of the whole world. viral etiology outbreaks of foodborne diseases have been improperly treated as less important than bacterial ones. rotavirus is the most reported cause of gastroenteritis and accounts for thousands of deaths annually. the present work reports a rotavirus-induced disease outbreak in a commercial establishment, where 51 employees related symptoms like diarrhea, vomits, nausea. water, food and beverages were analyzed microbiologically. no pathogenical bacterial contamination were detected, neither any modification on sensorial characteristics. according to the "attributable risk" of each food involved, bread and butter was considered suspicious food, and epidemiological approach pointed to the fact that the employee responsible for preparing this food was rotaviruses sicked just before the outbreak spreading.
Socio Psychological Counseling: How to Manage Identities?  [PDF]
Philippe Castel, Brigitte Minondo-Kaghad, Marie-Fran?oise Lacassagne
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.43A052
Abstract:

The work presented here is a research carried out into initiatives for returning the long-term unemployed to work. A small case group study based on international expertise in social categorization and communication was conducted in France. This analysis of “long-term unemployment” was done through the consequences for relationships with work with a view to suggesting a suitable remedial approach. The recommended socio psychological counseling is based on reconstructing the professional identity of the long-term unemployed person and implementing this before the return to a supported role that should serve as a springboard towards permanent employment. The results lead to extend this method to other social disabilities.

Abstract: Meat-grain-size (MGS) assessment is an empirical method for the early prediction of meat quality, a larger grain being synonymous with higher meat tenderness. The objective was to characterize 4 muscles (longissimus thoracis LT; rectus abdominis RA; longus colli LC; diaphragma D) of 5 coarse and 5 fine carcasses in terms of MGS in order to establish a link between muscular physicochemical properties and carcass MGS score. All comparisons were made of samples with similar fat content. The broiled sample hardness (shear force) was significantly higher for the coarse group than for the fine group (7.20 vs 5.89 kg; RA). Higher collagen content (27.94 vs 24.87 mg/g of dry matter in LT muscle; 15.86 vs 13.13 mg/g of dry matter in D muscle), higher oxidative metabolism (cytochrome-c oxidase; LT and D) but also higher glycolytic metabolism (lactate dehydrogenase; LT) were also observed in the coarse groups. Not all the muscles react in a similar way depending on the MGS group. Nevertheless, significant results are constant from one muscle to another, the RA being the only muscle for which the difference in hardness between the two groups is significant.
Benfotiamine, a synthetic S-acyl thiamine derivative, has different mechanisms of action and a different pharmacological profile than lipid-soluble thiamine disulfide derivatives

Abstract: Background Lipid-soluble thiamine precursors have a much higher bioavailability than genuine thiamine and therefore are more suitable for therapeutic purposes. Benfotiamine (S-benzoylthiamine O-monophosphate), an amphiphilic S-acyl thiamine derivative, prevents the progression of diabetic complications, probably by increasing tissue levels of thiamine diphosphate and so enhancing transketolase activity. As the brain is particularly sensitive to thiamine deficiency, we wanted to test whether intracellular thiamine and thiamine phosphate levels are increased in the brain after oral benfotiamine administration. Results Benfotiamine that is practically insoluble in water, organic solvents or oil was solubilized in 200 mM hydroxypropyl-β-cyclodextrin and the mice received a single oral administration of 100 mg/kg. Though thiamine levels rapidly increased in blood and liver to reach a maximum after one or two hours, no significant increase was observed in the brain. When mice received a daily oral administration of benfotiamine for 14 days, thiamine derivatives were increased significantly in the liver but not in the brain, compared to control mice. In addition, incubation of cultured neuroblastoma cells with 10 μM benfotiamine did not lead to increased intracellular thiamine levels. Moreover, in thiamine-depleted neuroblastoma cells, intracellular thiamine contents increased more rapidly after addition of thiamine to the culture medium than after addition of benfotiamine for which a lag period was observed. Conclusion Our results show that, though benfotiamine strongly increases thiamine levels in blood and liver, it has no significant effect in the brain. This would explain why beneficial effects of benfotiamine have only been observed in peripheral tissues, while sulbutiamine, a lipid-soluble thiamine disulfide derivative, that increases thiamine derivatives in the brain as well as in cultured cells, acts as a central nervous system drug. We propose that benfotiamine only penetrates the cells after dephosphorylation by intestinal alkaline phosphatases. It then enters the bloodstream as S-benzoylthiamine that is converted to thiamine in erythrocytes and in the liver. Benfotiamine, an S-acyl derivative practically insoluble in organic solvents, should therefore be differentiated from truly lipid-soluble thiamine disulfide derivatives (allithiamine and the synthetic sulbutiamine and fursultiamine) with a different mechanism of absorption and different pharmacological properties.

Abstract: The article investigates the implementation of the workplace health project ‘Body and Bureau’ at the Department of Development at the Copenhagen University Hospital. The project attempted to intervene with the daily routines of staff members, who were believed to be bodily inactive while performing their daily tasks. In seeking to add movement and exercise to the daily routines of staff members, ‘Body & Bureau’ was understood to promote a new pattern of behaviour in the office that would help avoiding life style conditions such as overweight, hypertension, pre-diabetes and increased levels of cholesterol, generally considered to expose office workers to increased risks of poor health. The article addresses the ways in which the bodies of staff members were objectified by the project and the ways in which it influenced their everyday lives, and how it became a catalyst for new modalities of social relations within the office. Subsequent to individual health tests being performed, a number of staff members were classified as being overweight, which led them to form what they ironically dubbed ‘The Group ofMourners’ in order to cope with their sense of sadness. About one month later, however, the group decided to become ‘The Group of Enthusiasts’, thereby taking on the tasks of changing the way they perceived of themselves and developing into an exercise support group. While the project had set out to promote movement as integral to the work routines, which was set against an undesirable notion of exercise for its own sake, the staff members ended up by pursuing the latter rather than the former. While the authors acknowledge the importance of tracing how bodies become objects of political power in the Foucauldian sense, they underscore that the nitty-gritty details of how projects play out in local social worlds such as the Development Department will eventually shape the trajectory of the intervention. Taking their cue from anthropologists Nancy Schepher-Hughes and Margaret Lock, the authors argue that a good starting point for the analysis of how a bodily objectifying project like that of ‘Body & Bureau’ intervenes in the social reality of an office is to pay equal attention to the political body, the individual body, and the social body. Similarly, these three perspectives on the body are used to explain how the state sponsored intervention politicizes the body of office workers, which leads to the testing and measuring of individual bodies, which finally becomes a collectivizing moment for staff members, because they eventually chose to socialize arou

Abstract: The restriction fragment length polymorphism of the 195 bp repeated DNA sequence of Trypanosoma cruzi was analyzed among 23 T. cruzi stocks giving a reliable picture of the whole phylogenetic variability of the species. The profiles observed with the enzymes Hinf I and Hae III were linked together and supported the existence of two groups. Group 1 shows a 195 bp repeated unit (Hinf I) and high molecular weight DNA (Hae III), while group 2 presents a ladder profile for each enzyme, which is a characteristic of tandemly repeated DNA. The two groups, respectively, clustered stocks pertaining to the two principal lineages evidenced by isoenzyme and RAPD markers. The congruence among these three independent genomic markers corroborates the existence of two real phylogenetic lineages in T. cruzi. The specific monomorphic profiles for each major phylogenetic lineage suggest the existence of ancient sexuality and cryptic biological speciation.

Computer Science , 2005,
Abstract: This paper presents some experiments in clustering homogeneous XMLdocuments to validate an existing classification or more generally anorganisational structure. Our approach integrates techniques for extracting knowledge from documents with unsupervised classification (clustering) of documents. We focus on the feature selection used for representing documents and its impact on the emerging classification. We mix the selection of structured features with fine textual selection based on syntactic characteristics.We illustrate and evaluate this approach with a collection of Inria activity reports for the year 2003. The objective is to cluster projects into larger groups (Themes), based on the keywords or different chapters of these activity reports. We then compare the results of clustering using different feature selections, with the official theme structure used by Inria.

Advances in Physical Education (APE) , 2012, DOI: 10.4236/ape.2012.23019
Abstract: This study aims at assessing the modifications of renal parameters with 13 female players of the same Benin team-amateur Division 1, during two consecutive handball games played 26 hours apart. The players are divided into two groups: starters (ST: N = 7) and nonstarters (NS: N = 6). The estimated glomerular filtration rate (eGFR) with Cockcroft-Gault and MDRD formulae, the fractional excretion of sodium (FeNa), the plasma haemoglobin (Hb) and albumin (Alb) were assayed at rest and at the end of each game. At the end of the first game, only eGFR decreased significantly by at least 16.30% (p < 0.05) in ST only. At the end of the second game, the average reductions of eGFR are significant in both the ST and NS groups (p < 0.05), but they are less important than those recorded at the end of the first (p > 0.05). FeNa varied in no group, neither after the first game, nor after the second (p > 0.05). But a cumulative reduction is observed between the values before the first and those recorded at the end of the second game in both ST and NS groups. The status of the players (ST or NS) did not influence the results. Two games of handball played 26 hours apart in the sub-Saharan environment of Cotonou caused in girls, a transitory decrease in eGFR without a cumulative effect. FeNa decreased too, but with a cumulative effect which indicates large sodium retention.

Abstract: This paper presents insights and perceptions of stakeholders involved in the development and implementation of residential smart grid pilot projects in the Netherlands, adding to the limited information that is currently available in this area, while expectations about the potential benefits of smart grids are high. The main research questions of this study are: (1) How have some typical residential smart grid pilots in the Netherlands been set up? (2) Which stakeholders are involved in these pilots in the year 2014? (3) What are their views and perceptions with regards to the development and performance of residential smart grids? and (4) What do these stakeholders think about the products and services that may support an active participation of end-users in a smart energy home? To obtain information, we evaluated five residential smart grid pilot projects where smart energy products and services have been implemented. Semi-structured interviews were conducted with nine stakeholders involved in these projects. The Strategic Niche management framework was used to identify the present state of development and implementation of smart grid pilots. Our study shows that in the Netherlands residential smart grid pilots have been set-up and funded mainly by the government and grid operators. Other stakeholders involved include energy suppliers, end-users (as an energy cooperative or individual household), product and service suppliers, Information and Communication Technology (ICT) companies, and knowledge institutes. Currently a technology-push approach exists which barely includes an integrated approach towards smart grids products and services development. To the opinion of the interviewed stakeholders, current products and services offered in residential smart grid pilots are functionally attractive, but often too technically complex for the understanding of end-users. Hence, the general view held by respondents is that end-users should be the starting point in the development of smart grid products and services at the residential areas.
