Poorly water-soluble drugs such as nifedipine (NIF) (similar to 20 mu g/mL) offer challenging problems in drug formulation as poor solubility is generally associated with poor dissolution characteristics and thus with poor oral bioavailability (BCS class H drugs). In order to enhance these characteristics, formulation of NIF as nanocrystals was carried out. NIF nanoparticles (NP) were prepared using high-pressure homogenization (HPH). Solubility and dissolution characteristics have been reported in previous work to be significantly enhanced for NIF NP. Influence of NIF particle size on NIF permeation rate across intestinal cell models (Caco-2 and HT29-5M21 cultures and co-cultures) was investigated in order to complement these promising in vitro data. Apical to basolateral transfer studies were carried out across Caco-2 and HT29-5M21 cultures and co-cultures. Caco-2/HT29-5M21 co-cultures (seeding ratio 3: 1) were evaluated to better represent in vivo intestinal conditions. The influence of chitosan in the NIF NP formulation with regard to in vitro NIF permeation rate was also evaluated. These studies showed that NIF permeation rate across the different in vitro models evaluated can be significantly enhanced (approximate to 6-fold) by formulation of NIF as nanoparticles. No significant difference was observed either in the presence of chitosan in the formulation or between the three cell models evaluated. To complement these observations, preliminary in vivo pharmacokinetic evaluations in Sprague-Dawley rats, in the fed and fasted states, were also carried out for both un-milled NIF and NIF NP.

The increased concern about environmental effect of off-target deposits of pesticides use has resulted in the development of numerous spray drift models. Statistical models based on experimental field studies are used to estimate off-target deposits for different sprayers in various environmental conditions. Random-walk and computational fluid dynamics (CFD) models have been used to predict the effect of operational parameters and were extensively validated in wind tunnel. A third group, Gaussian dispersion models have been used for several years for the environmental assessment of the pesticide spray drift, mainly for aerial application. When these models were used for the evaluation of boom sprayer spray drift, their predictions were found unreliable in the short range, were the initial release conditions of the droplets have a significant effect on the spray deposits. For longer ranges, the results were found consistent with the field measurements as the characteristics of the source have a reduced influence on the small droplets drift. Three major parameters must be taken into account in order to define realistic initial conditions of the droplets in a spray drift model: the spray pattern of the nozzle, the boom movements and the effect of entrained air and droplet velocities. To take theses parameters into account in a Gaussian model, the nozzle droplet size distribution measured with a Malvern laser particle analyser was used to divide the nozzle output into several size classes. The spray deposits of each diameter class was computed for each successive position of the nozzle combining the nozzle spray distribution with drift computed with a Gaussian tilting plume model. The summation of these footprints resulted in the global drift of the nozzle. For increasing droplet size, the release height used in the Gaussian model was decreased from nozzle height to ground level using an experimental law to take into account the effect of entrained air and droplet initial velocity. The experimental law was adjusted on 2m/s wind tunnel measurements and robustness was evaluated for 1 and 4 m/s. [less ▲]

Les auteures envisagent l’écriture comme un instrument de construction de savoirs et de développement de la réflexivité chez les futurs professionnels de l’enseignement. Or, les données recueillies dans leurs recherches relèvent des réticences à écrire chez de nombreux étudiants. Il y a lieu de comprendre ces réticences avant d’élaborer des dispositifs visant dans un premier temps la réconciliation de ces étudiants avec l’écrit, pour qu’ils puissent ensuite y recourir pour élaborer leurs savoirs professionnels et opérer des liaisons entre la théorie et la pratique. Afin que de tels dispositifs ne profitent pas seulement à ceux qui possèdent déjà une bonne maitrise du langage écrit, il importe de les intégrer dans des processus de socialisation et d’accompagnement tout en outillant la production de textes réflexifs.

L'abondance de matières colorantes sur certains sites d’habitat sans art pariétal indique qu’il existait probablement des utilisations artisanales et domestiques des ces minéraux. L’utilisation de ces matériaux nécessitait l’élaboration de chaînes opératoires de production qu’il a été possible de reconstituer à travers l’étude des matières colorantes provenant des sites solutréens de Combe Saunière (Dordogne), Fressignes (Indre) et Les Maîtreaux (Indre-et-Loire). L'hématite, produisant une poudre rouge, et les oxydes de manganèse, produisant une poudre noire, sont les matières colorantes préférentiellement recherchées par les Solutréens. Il a été possible de mettre en évidence le chauffage des matières colorantes jaune, qui a pour but la production d'hématite. A Combe Saunière et à Fressignes, le contexte ne permet pas de trancher en faveur d’un chauffage volontaire. En revanche, sur le site des Maîtreaux, une aire de 20 m2 environ concentre des matières colorantes qui ont été triées, stockées et transformées par chauffage. Un certain nombre de matières colorantes rouges résultent du chauffage intentionnel et contrôlé des matières colorantes jaunes. De plus, des indices indéniables de réduction en poudre des matières colorantes rouges jonchent cet espace. L’aire de 20 m² définit un véritable atelier de préparation des matières colorantes, inédit à ce jour. Par ailleurs, le statut économique du site et la richesse des ressources de matières colorantes dans l'environnement immédiat du campement sont intimement liés à la nature des restes abandonnés sur les sites. Ainsi, sur le site d’habitat saisonnier de Combe Saunière, les matières colorantes, dont l'environnement immédiat est riche et varié, ont été clairement réduites en poudre et utilisées directement sans trop de transformations. Sur la halte de chasse de Fressignes, les matières colorantes, inexistantes autour du site sont extrêmement rares et ont été exploitées au maximum de leur capacité par réduction en poudre. Sur le site d’atelier de taille du silex des Maîtreaux, les matières colorantes ont été préparées, transformées, triées et stockées. Leur utilisation devait avoir lieu sur un autre gisement.

Les pouvoirs adjudicateurs désirant avoir une consommation responsable, favorable au développement durable, hésitent souvent à insérer des considérations "autres que strictement économiques" dans leurs procédures d'achat et donc à valoriser les spécificités des entreprises d'économie sociale. Mais d'où vient cette hésitation? L'argument généralement avancé est le fait que l'insertion de considérations autres que strictement économiques va à l'encontre de la logique de marché imposée par la législation nationale, le droit communautaire ou encore l'Accord sur les marchés publics. L'exercice leur apparait dès lors difficile et périlleux. Qu'en est-il de l'état du droit aujourd'hui? [less ▲]

The prescription of a pharmacological agent concludes most medical visits. The rational basis of drug prescription by the physician relies on numerous pharmacodynamic, pharmacokinetic, pragmatic and economic considerations. However, it is a pity to notice that one patient out of two does not strictly follow the pharmacological treatment as it was prescribed. This article analyses some problems of the patient-doctor relationship, which may reduce medication compliance, and provides practical advice for improving such a situation in order to enhance both efficacy and safety of drug prescribing.

BACKGROUND: Eotaxin (chemokine, CC motif, ligand; CCL11) is a potent eosinophil chemoattractant strongly implicated in the pathobiology of asthma. Genetic variation at the CCL11 locus has been correlated with serum total IgE, blood eosinophil counts, and circulating eotaxin protein levels in several case-control asthma studies. Family-based association studies of CCL11 genetic variants have not been reported to date. OBJECTIVE: To evaluate 9 common CCL11 single nucleotide polymorphisms (SNPs) in nuclear families ascertained through patients with asthma participating in the Childhood Asthma Management Program study. METHODS: Single nucleotide polymorphism genotyping was performed by using minisequencing and probe hybridization platforms. Family-based association analysis for asthma and 4 asthma-related intermediate quantitative phenotypes was performed by using FBAT. RESULTS: One SNP, -384A>G, was associated with asthma among African American families (P = .01). CCL11 SNPs and haplotypes were not associated with asthma among white or Hispanic families. Two low-frequency alleles in strong pairwise linkage disequilibrium, -426C and IVS2+199A, were associated with lower serum total IgE levels (P = .0006 and P = .009, respectively) in white families, whereas 2 more common variants, -576C and g.4438C, were associated with higher IgE levels in African American families (P = .01-.04). Haplotype analysis in the white cohort provided additional evidence of association with serum total IgE, implicating 2 haplotypes. No single SNP or haplotype associations were observed with blood eosinophil levels, FEV(1), or airway responsiveness. CONCLUSION: These findings provide further evidence that genetic variation at the CCL11 locus is an important determinant of serum total IgE levels among patients with asthma. [less ▲]

This paper compares two methods based on machine vision to provide driver assistance in seed drill guidance in order to improve spacing accuracy during contiguous passages. The first case consisted of following the furrow created at the preceding passage by a special marker disc attached to the seed drill. A camera was located on the tractor and detected this furrow. In the second case, the seed rows themselves were detected by the camera without making use of the marker disc. In both cases, several video sequences were acquired in various situations, including different soil textures and various illumination conditions (375 sequences were acquired during three years). A pre-treatment of these sequences was performed and included a background subtraction in order to remove shadows and other wide unevenness. In the first case, the best results were obtained by using an image treatment based on the Hough transform coupled to a recursive filter. The search of the maximum of the Hough transform was performed using a mean shift algorithm. In the second case, where several parallel rows were simultaneously present on the images, an adapted Hough transform was proposed which took into account the a priori knowledge of the rows spacing. The trueness and precision in row detection were superior in the second case. The results are compatible with the application, since the trueness was smaller than 30 mm. This suggested that it can be possible to assist the manual guidance of a seed drill by an automatic system consisting in a camera detecting the seed rows. [less ▲]

Studies of lysozyme have played a major role over several decades in defining the general principles underlying protein structure, folding, and stability. Following the discovery some 10 years ago that two mutational variants of lysozyme are associated with systemic amyloidosis, these studies have been extended to investigate the mechanism of amyloid fibril formation. This Account describes our present knowledge of lysozyme folding and misfolding, and how the latter can give rise to amyloid disease. It also discusses the significance of these studies for our general understanding of normal and aberrant protein folding in the context of human health and disease. [less ▲]
