Abstract

Intestinal parasitism and its epidemiological characteristics were studied in an isolated Amerindian population from Upper Oyapock (French Guiana) that has retained its traditional social and cultural specificities. This population consisted of 138 Wayampi Indians, 68 adults and 70 children (below the age of 15 years), with a sex ratio (M/F) of 0.86, spread over the four villages of the community of Trois Sauts, corresponding to more than two thirds of the population recorded as inhabiting the sector in the last census (375 inhabitants). Fecal examination combined the direct examination of fresh feces with the quantitative techniques of Kato-Katz method, Baermann and MIF staining. Overall, 92 % of the subjects were found to have intestinal parasites, 85 % if only direct examination of fresh stools was taken into account. Fourteen species of human parasite were identified: seven protozoa and seven helminths. We observed in particular 1) a high frequency of hookworm infection due to Necator americanus. Over 50 % of subjects were affected, with a range of 25 % to 75 % according to the village, but with only moderate parasite loads; 2) a high level of parasitism by E. histolytica/E. dispar (17 %), Stongyloides stercoralis (16 %) and Hymenolepis nana (18%) ; 3)a lower level of parasitism by Ascaris lumbricoides and very low levels (almost absent) of Trichiuris trichiura ; 4) the absence of Schistosoma and fluke eggs. With the exception of H. nana, which was more frequent in children than in adults, there was no significant difference in the level of parasitism according to sex and age. Although the Wayampi of French Guiana are French citizens and consequently have quite high incomes and ready access to clinics and medicines, intestinal parasites are far from under control in this population. A lack of fecal hygiene and the habit of walking barefoot are widespread in the unchanging Amazonian environment and contribute to this phenomenon.

Abstract

In the present study, experiments were carried out in a single-cylinder downsized SI engine with different rates of oxygen (15% to 27% by volume in the total mixture of intake gases except fuel) and equivalence ratios (from 0.45 to 1). Therefore, the oxygen volume fraction is due to oxygen enrichment or nitrogen dilution. The study of the impact of controlling the oxygen concentration on the combustion characteristics and emissions was performed at 1 400 rpm, at several loads (Indicated Mean Effective Pressure (IMEP) from 400 to 1 000 kPa). For each operation point, the spark advance and the intake pressure were adjusted simultaneously in order to maintain the load and obtain a minimum value of the indicated Specific Fuel Consumption (SFC). The effect of the oxygen concentration on the engine combustion characteristics was simulated by using the commercial software AMESim, with the combustion model developed by IFP Energies nouvelles, and an adapted algorithm was used to avoid residual gas calibration. By implementing a correlation for the laminar burning velocity, the in-cylinder pressures were perfectly predicted with a maximum pressure relative error of less than 2% for almost all the operating points. The classification of engine combustion according to the Peters-Borghi diagram, gives a deeper insight into the interaction between turbulence and the flame front.

Abstract

A comparative analysis of the spalling of (a) cores made of 3 concrete mixes embedded into 3 slabs made of the 3 same concrete mixes; and (b) 3 reference slabs made again of the same 3 concrete mixes has been made. Samples have been exposed to the French Increased HydroCarbon temperature curve. Results confirm that concrete spalling phenomena is not only related to the material properties. Concrete spalling is also very much influenced by the geometry of the samples.

Abstract

Several concrete mixes have been designed to evaluate the influence of an air entraining agent (AEA) on spalling. Tests have been performed under the ISO curve (occasionally under the HCinc curve) on specimens of various sizes and shapes to assess spalling. Results were somehow erratic on the smallest specimens whereas the beneficial effect of the air-bubble network could be emphasized on slabs.

Abstract

OBJECTIVE: Whole-cell (WC) modeling is a promising tool for biological research, bioengineering, and medicine. However, substantial work remains to create accurate comprehensive models of complex cells. METHODS: We organized the 2015 Whole-Cell Modeling Summer School to teach WC modeling and evaluate the need for new WC modeling standards and software by recoding a recently published WC model in the Systems Biology Markup Language. RESULTS: Our analysis revealed several challenges to representing WC models using the current standards. CONCLUSION: We, therefore, propose several new WC modeling standards, software, and databases. SIGNIFICANCE: We anticipate that these new standards and software will enable more comprehensive models.

Abstract

Abundant evidence over past decades shows that foods with added plant sterols and plant stanols lower serum LDL cholesterol concentrations. However, despite the overwhelming data, numerous scientific questions still remain. The objective of this paper is to summarize the considerations of 60 academic and industrial experts who participated in the scientific meeting in Maastricht, the Netherlands, on issues related to the health effects of plant sterols and plant stanols. The meeting participants discussed issues including efficacy profiling, heterogeneity in responsiveness, effects beyond LDL-C lowering, and food formulation aspects of plant sterol and stanol consumption. Furthermore, aspects related to the potential atherogenicity of elevated circulatory plant sterol concentrations were discussed. Until the potential atherogenicity of plant sterols is resolved, based on the results >200 clinical trials, the risk to benefit of plant sterol use is favorable. Evidence on these topics in plant sterol and plant stanol research was presented and used to reach consensus where possible. It was concluded that endpoint studies looking at plant sterol and plant stanol efficacy are needed, however, there was no clear opinion on the best marker and best design for such a study. Based on the current scientific evidence, plant sterols and plant stanols are recommended for use as dietary options to lower serum cholesterol. © 2012.

25. Staphylococcus aureusIsolated in Cases of Impetigo Produces Both Epidermolysin A or B and LukE-LukD in 78% of 131 Retrospective and Prospective Cases

Author

Gravet, A., Couppie´, P., Meunier, O., Clyti, E., Moreau, B., Pradinaud, R., Monteil, H., and Pre´vost, G.

Abstract

ABSTRACTClinical symptoms of impetigo and staphylococcal scalded skin syndrome may not only be expressed as the splitting of cell layers within the epidermis but are often accompanied by some localized inflammation. Toxin patterns of Staphylococcus aureusisolates originating from patients with impetigo and also from those with other primary and secondary skin infections in a retrospective isolate collection in France and a prospective isolate collection in French Guiana revealed a significant association (75% of the cases studied) of impetigo with production of at least one of the epidermolysins A and B and the bicomponent leucotoxin LukE-LukD (P< 0.001). However, most of the isolates were able to produce one of the nonubiquitous enterotoxins. Pulsed-field gel electrophoresis (PFGE) of genomic DNA hydrolyzed withSmaI showed a polymorphism of the two groups of isolates despite the fact that endemic clones were suspected in French Guiana and France. The combination of toxin patterns with PFGE fingerprinting may provide further discrimination among isolates defined in a given cluster or a given pulsotype and account for a specific virulence. The new association of toxins with a clinical syndrome may reveal principles of the pathological process.

Abstract

Dans les conditions climatiques de l'île de la Réunion l'étude du développement du bananier (cv. "Americani", type de taille moyenne du sous-groupe Cavendish, AAA) est indispensable pour diriger la production et limiter le saisonnement du à l'hiver austral. Une expérimentation a été mise en place dans la région sud (Bassin Martin) : 3 traitements correspondant à 3 époques de plantation. (I= mi-novembre 1973. II= mi-mars 1974; III= mi-juillet 1974). Les observations ont été faites sur 3 cycles successifs sur la croissance la floraison et la récolte. Conditions climatiques de la région : 1398 mm de precipitations/an, 2743 h/an d'insolation. Altitude : 300 m; sols évolués de type ferrallitique brun, les techniques culturales d'un système intensif ont été appliquées. L'essai a permis de connaître l'influence du climat sur la longeur des cycles, de situer les époques de récoltes et leur étalement en fonction des dates de plantation

Abstract

A semi-empirical method for electronic correlation energy calculations, recently proposed by Liévin and al. (refs.1,3), is discussed in regard to its domain of applicability. Although the economical version of this method was primarily limited to the calculation of reaction energies, it is proposed here to extend the use of this version to the study of potential surfaces associated with the fundamental state of a supermolecule. A few points of the potential surface of 2 CN are examined as an example. © 1984., SCOPUS: ar.j, info:eu-repo/semantics/published
