In this article methods are shown to use software in the loop (SIL) and hardware in the loop (HIL) techniques in connection with the microscopic traffic flow simulation program PELOPS. With some application examples the use of these methods are depicted. In this context the ossibilities of such coupled simulation tools in development of driver assistance systems are presented. An outlook is given to future enhancements of the described HIL techniques to control for example test benches or assess real vehicles in virtual traffic. [less ▲]

Irwin et al. (2003) pointed out the principles that quality PE teachers should incorporate into their pedagogical practice in order to take into account the increasing number of overweight and obese students in their classes. Fighting against obesity is so complex that no simple solution can be proposed. It means that the development of specific tools providing PE teachers with new instructional strategies inspired from public health is needed (Prusak et al., 2011). Inclusion of overweight students into PE can be linked with a social ecological model (Li & Rukavina, 2012). Even if PE teachers are able to develop and implement specific instructional strategies, it seems that they need support from health experts (Cloes et al., 2013). Internet, continuing professional development activities, and educational info capsules were identified as the preferred supports to be used by the practitioners (Cloes et al., 2014). The aims of this study were to produce and validate three pedagogical capsules focusing on specific concerns of PE teachers as well as to analyze the procedure of validation. Using an extensive analysis of the literature, the researchers first identified theoretical and practical resources to be mobilized in the understanding and development of solutions for the selected problems: (1) Students’ lack of awareness about the risks of overweight and obesity; (2) Constraints associated with the motor/physical disabling; (3) Parents’ lack of awareness about PA impact on health. The capsules were then submitted to 11 experts (health specialists, health educators, psychologists, PE teachers) who had to analyze the documents. They acknowledged the content and form of the capsules. Minor changes were requested in order to finalize them. The proposed evaluation sheet was also validated but face-to-face assessment was recommended. Dissemination of the existing capsules as well as development of additional ones should be the next steps of this project. [less ▲]

Wound dressing is one of the most promising medical applications for chitosan, due to its adhesive nature, together with some biological properties including bacteriostatic and fungistatic properties that help in faster wound healing. In this work we propose a chitosan biomimetic scaffolds and methods for modulating their intrinsic properties such as rigidity, elasticity, resistance to mechanical stress, porosity, biodegradation and absorbance of exudates. Therefore, the chitosan scaffold comprising at least two fused layers, wherein the advantage of a first fused layer composed of a chitosan electrospun nanofiber membrane are oxygen-permeability, high porosity, variable pore-size distribution, high surface to volume ratio, and most importantly, morphological similarity to natural extracellular matrix in skin, which promote cell adhesion migration and proliferation. The advantages of a second fused layer comprising a porous chitosan support layer are improving mechanical property, good absorption capacities to remove excess exudates and good water and gas exchange. Moreover, the scaffold was characterized by (i) a good adhesion between the porous and nanofiber layers, (ii) a tuneable porosity of the nanofiber layer by tuning the distance between the nanofibers, (iii) a stable nanofibers and porous morphology even when immersed in water. Finally, the scaffolds have shown tremendous promise as a wound dressing, in tissue engineering. The three main human cell types fibroblasts, endothelial cells and keratinocytes was cultured in vitro on electrospun nanofibers scaffold. Properties of electrospun chitosan scaffold and chitosan sponges obtained by lyophilization were also compared in vivo, in order to evaluate importance of the 3D-architecture of the biomaterial.

Mosquitoes (Diptera: Culicidae) are zoonotic vectors responsible for numerous infectious diseases of medical and veterinary importance such as filariasis, malaria and encephalitis. As part of an integrated vector control, entomopathogenic fungi could be developed as biopesticides in two ways: spores and metabolites recognized as effective virulence factors. Solid-state fermentation enhances spore production and induces the secretion of metabolites quantitatively and qualitatively different from submerged fermentation, which impairs fungal metabolic efficiency. In this context, we showed high spore productivity of solid-state media based on agro-industrial substrates as wheat bran. Spores remained pathogenic, as revealed by classical toxicity tests and electron microscopy. However, the absence of free water makes culture parameter variations difficult to control in large-scale. Recently, we performed a bioreactor design intended for simultaneous spore and metabolite production, combining the technological advantages of submerged and solid-state fermentations. Biofilm fermentation (i.e. growth of fungal biomass on an inert support immerged in a nutrient medium) is a tremendous production system favouring the secretion of insecticidal metabolites in the liquid medium as we showed recently. This is also an interesting tool to provide an overview of the complexity of the metabolic pathways involved in the regulation of extracellular metabolites secretion because corresponding genes are reported to be differentially expressed from classical fermentation systems. Researches in vector control are currently intensified. In this context, the identification of genes and metabolites specifically expressed during biofilm fermentation will help to develop new technologies related both to the design of bioreactor and the production of insecticidal proteins.

Laminitis is a painful systemic disease of which the principal manifestation is a diffuse aseptic pododermatitis. An ischaemia-reperfusion and/or an activation of matrix métalloproteinases following a proinflammatory status (mainly gastro-intestinal) or hormonal disorders involving metabolic dysfunctions related to the development of insulin resistance, are at the origin of laminitis. The presence of histological lesions of keratinocytes and endothelial cells, and the infiltration of polymorphonuclear neutrophils (PMNs) in laminar tissues, warranted the development of the two cellular culture models corresponding for the study of this disease. Therefore, keratinocytes and endothelial cells are isolated by enzymatic digestion and mechanical separation, respectively from coronary bands and carotids, and are put in culture under controlled atmosphere in DMEM supplemented with additives. Microscopic observations of phenotype, the immunocytochemistry, growth curves, and apoptosis stainings allowed to characterize the cells. The cells can be used, between passage 3 and 5 for the keratinocytes and 3 and 6 for the endothelial cells, in models of interaction with PMNs and their enzymes, in condition of anoxia/reoxygenation with variable glucose.concentrations.

The classic view of brain and behavioral sexual differentiation holds that the neural mechanisms controlling sexual behavior in female rodents develop in the absence of ovarian sex hormone actions. However, in a previous study, female aromatase knock-out (ArKO) mice, which cannot convert testosterone to estradiol, showed deficient male-oriented partner preference and lordosis behaviors in response to adult ovarian hormones, raising the possibility that estradiol may contribute to the development of these female sexual behaviors. In the present experiments, administering estradiol prepubertally [between postnatal day 15 (P15) and P25] significantly enhanced the ability of ArKO female mice to display lordosis behavior in response to ovarian hormones administered later in adulthood, whereas treatment with estradiol over an earlier postnatal period (P5-P15) had no such effect. Treatment of ArKO females with estradiol between P15 and P25 also rescued their later preference to approach distal cues from an intact male over an estrous female. ArKO females also displayed significantly less female-directed (male-typical) mounting behavior than wild-type control females when treated with testosterone in adulthood. Prepubertal estradiol treatment failed to reverse this deficit in ArKO females, whereas earlier postnatal estradiol augmented later mounting in both genotypes. Our results provide new evidence for an organizing role of prepubertal estradiol in the development of neural mechanisms that control female-typical sexual behavior. [less ▲]
