Cefotaxime acts synergistically with levofloxacin in experimental meningitis due to penicillin-resistant pneumococci and prevents selection of levofloxacin-resistant mutants in vitro.

Cefotaxime, given in two doses (each 100 mg/kg of body weight), produced a good bactericidal activity (-0.47 Deltalog(10) CFU/ml. h) which was comparable to that of levofloxacin (-0.49 Deltalog(10) CFU/ml. h) against a penicillin-resistant pneumococcal strain WB4 in experimental meningitis. Cefotaxime combined with levofloxacin acted synergistically (-1.04 Deltalog(10) CFU/ml. h). Synergy between cefotaxime and levofloxacin was also demonstrated in vitro in time killing assays and with the checkerboard method for two penicillin-resistant strains (WB4 and KR4). Using in vitro cycling experiments, the addition of cefotaxime in sub-MIC concentrations (one-eighth of the MIC) drastically reduced levofloxacin-induced resistance in the same two strains (64-fold increase of the MIC of levofloxacin after 12 cycles versus 2-fold increase of the MIC of levofloxacin combined with cefotaxime). Mutations detected in the genes encoding topoisomerase IV (parC and parE) and gyrase (gyrA and gyrB) confirmed the levofloxacin-induced resistance in both strains. Addition of cefotaxime in low doses was able to suppress levofloxacin-induced resistance.

Interpretation of partial fingermarks using an automated fingerprint identification system

Abstract : In the subject of fingerprints, the rise of computers tools made it possible to create powerful automated search algorithms. These algorithms allow, inter alia, to compare a fingermark to a fingerprint database and therefore to establish a link between the mark and a known source. With the growth of the capacities of these systems and of data storage, as well as increasing collaboration between police services on the international level, the size of these databases increases. The current challenge for the field of fingerprint identification consists of the growth of these databases, which makes it possible to find impressions that are very similar but coming from distinct fingers. However and simultaneously, this data and these systems allow a description of the variability between different impressions from a same finger and between impressions from different fingers. This statistical description of the withinand between-finger variabilities computed on the basis of minutiae and their relative positions can then be utilized in a statistical approach to interpretation. The computation of a likelihood ratio, employing simultaneously the comparison between the mark and the print of the case, the within-variability of the suspects' finger and the between-variability of the mark with respect to a database, can then be based on representative data. Thus, these data allow an evaluation which may be more detailed than that obtained by the application of rules established long before the advent of these large databases or by the specialists experience. The goal of the present thesis is to evaluate likelihood ratios, computed based on the scores of an automated fingerprint identification system when the source of the tested and compared marks is known. These ratios must support the hypothesis which it is known to be true. Moreover, they should support this hypothesis more and more strongly with the addition of information in the form of additional minutiae. For the modeling of within- and between-variability, the necessary data were defined, and acquired for one finger of a first donor, and two fingers of a second donor. The database used for between-variability includes approximately 600000 inked prints. The minimal number of observations necessary for a robust estimation was determined for the two distributions used. Factors which influence these distributions were also analyzed: the number of minutiae included in the configuration and the configuration as such for both distributions, as well as the finger number and the general pattern for between-variability, and the orientation of the minutiae for within-variability. In the present study, the only factor for which no influence has been shown is the orientation of minutiae The results show that the likelihood ratios resulting from the use of the scores of an AFIS can be used for evaluation. Relatively low rates of likelihood ratios supporting the hypothesis known to be false have been obtained. The maximum rate of likelihood ratios supporting the hypothesis that the two impressions were left by the same finger when the impressions came from different fingers obtained is of 5.2 %, for a configuration of 6 minutiae. When a 7th then an 8th minutia are added, this rate lowers to 3.2 %, then to 0.8 %. In parallel, for these same configurations, the likelihood ratios obtained are on average of the order of 100,1000, and 10000 for 6,7 and 8 minutiae when the two impressions come from the same finger. These likelihood ratios can therefore be an important aid for decision making. Both positive evolutions linked to the addition of minutiae (a drop in the rates of likelihood ratios which can lead to an erroneous decision and an increase in the value of the likelihood ratio) were observed in a systematic way within the framework of the study. Approximations based on 3 scores for within-variability and on 10 scores for between-variability were found, and showed satisfactory results. Résumé : Dans le domaine des empreintes digitales, l'essor des outils informatisés a permis de créer de puissants algorithmes de recherche automatique. Ces algorithmes permettent, entre autres, de comparer une trace à une banque de données d'empreintes digitales de source connue. Ainsi, le lien entre la trace et l'une de ces sources peut être établi. Avec la croissance des capacités de ces systèmes, des potentiels de stockage de données, ainsi qu'avec une collaboration accrue au niveau international entre les services de police, la taille des banques de données augmente. Le défi actuel pour le domaine de l'identification par empreintes digitales consiste en la croissance de ces banques de données, qui peut permettre de trouver des impressions très similaires mais provenant de doigts distincts. Toutefois et simultanément, ces données et ces systèmes permettent une description des variabilités entre différentes appositions d'un même doigt, et entre les appositions de différents doigts, basées sur des larges quantités de données. Cette description statistique de l'intra- et de l'intervariabilité calculée à partir des minuties et de leurs positions relatives va s'insérer dans une approche d'interprétation probabiliste. Le calcul d'un rapport de vraisemblance, qui fait intervenir simultanément la comparaison entre la trace et l'empreinte du cas, ainsi que l'intravariabilité du doigt du suspect et l'intervariabilité de la trace par rapport à une banque de données, peut alors se baser sur des jeux de données représentatifs. Ainsi, ces données permettent d'aboutir à une évaluation beaucoup plus fine que celle obtenue par l'application de règles établies bien avant l'avènement de ces grandes banques ou par la seule expérience du spécialiste. L'objectif de la présente thèse est d'évaluer des rapports de vraisemblance calcul és à partir des scores d'un système automatique lorsqu'on connaît la source des traces testées et comparées. Ces rapports doivent soutenir l'hypothèse dont il est connu qu'elle est vraie. De plus, ils devraient soutenir de plus en plus fortement cette hypothèse avec l'ajout d'information sous la forme de minuties additionnelles. Pour la modélisation de l'intra- et l'intervariabilité, les données nécessaires ont été définies, et acquises pour un doigt d'un premier donneur, et deux doigts d'un second donneur. La banque de données utilisée pour l'intervariabilité inclut environ 600000 empreintes encrées. Le nombre minimal d'observations nécessaire pour une estimation robuste a été déterminé pour les deux distributions utilisées. Des facteurs qui influencent ces distributions ont, par la suite, été analysés: le nombre de minuties inclus dans la configuration et la configuration en tant que telle pour les deux distributions, ainsi que le numéro du doigt et le dessin général pour l'intervariabilité, et la orientation des minuties pour l'intravariabilité. Parmi tous ces facteurs, l'orientation des minuties est le seul dont une influence n'a pas été démontrée dans la présente étude. Les résultats montrent que les rapports de vraisemblance issus de l'utilisation des scores de l'AFIS peuvent être utilisés à des fins évaluatifs. Des taux de rapports de vraisemblance relativement bas soutiennent l'hypothèse que l'on sait fausse. Le taux maximal de rapports de vraisemblance soutenant l'hypothèse que les deux impressions aient été laissées par le même doigt alors qu'en réalité les impressions viennent de doigts différents obtenu est de 5.2%, pour une configuration de 6 minuties. Lorsqu'une 7ème puis une 8ème minutie sont ajoutées, ce taux baisse d'abord à 3.2%, puis à 0.8%. Parallèlement, pour ces mêmes configurations, les rapports de vraisemblance sont en moyenne de l'ordre de 100, 1000, et 10000 pour 6, 7 et 8 minuties lorsque les deux impressions proviennent du même doigt. Ces rapports de vraisemblance peuvent donc apporter un soutien important à la prise de décision. Les deux évolutions positives liées à l'ajout de minuties (baisse des taux qui peuvent amener à une décision erronée et augmentation de la valeur du rapport de vraisemblance) ont été observées de façon systématique dans le cadre de l'étude. Des approximations basées sur 3 scores pour l'intravariabilité et sur 10 scores pour l'intervariabilité ont été trouvées, et ont montré des résultats satisfaisants.

Maturation protéolytique et sécrétion de la rénine: importance fonctionnelle de la pro-région

RÉSUMÉ Le système rénine-angiotensine joue un rôle prépondérant dans la régulation de la pression sanguine et de la balance des sels ainsi que dans d'autres processus physiologiques et pathologiques. Lorsque la pression sanguine est trop basse, les cellules juxtaglomérulaires sécrètent la rénine, qui clivera l'angiotensinogène circulant (sécrété majoritairement par le foie) pour libérer l'angiotensine I, qui sera alors transformée en angiotensine II par l'enzyme de conversion de l'angiotensine. Ce système est régulé au niveau de la sécrétion de la rénine par le rein. La rénine est une enzyme de type protéase aspartique. Elle est produite sous la forme d'un précurseur inactif de haut poids moléculaire appelé prorénine, qui peut être transformé en rénine active. Si le rôle de la prorégion de la rénine n'est pas encore connu, plusieurs études ont montré qu'elle pourrait être un auto-inhibiteur. Des travaux menés sur d'autres enzymes protéolytique ont mis en évidence un rôle de chaperon de leurs prorégions. Dans la circulation, la prorénine est majoritaire (90%) et la rénine active ne représente que 10% de la rénine circulante. L'enzyme qui transforme, in vivo, la prorénine en rénine active n'est pas connue. De même, l'endroit précis du clivage n'est pas élucidé. Dans ce travail, nous avons généré plusieurs mutants de la prorénine et les avons exprimés dans deux types cellulaires : les CV1 (modèle constitutif) et AtT-20 (modèle régulé). Nous avons montré que la prorégion joue un rôle important aussi bien dans l'acquisition de l'activité enzymatique que dans la sécrétion de la rénine, mais fonctionne différemment d'un type cellulaire à l'autre. Nous avons montré pour la première fois que la prorégion interagit de façon intermoléculaire à l'intérieur de la cellule. Les expériences de complémentation montre que l'interaction favorable de la rénine avec la prorégion dépend de la taille de cette dernière : prorénine (383 acides aminés) > pro62 (62 acides aminés) > pro43 (43 acides aminés). Par ailleurs nos résultats montrent qu'une faible partie de la rénine est dirigée vers la voie de sécrétion régulée classique tandis que la majorité est dirigée vers les lysosomes. Ceci suggère qu'une internalisation de la rénine circulante via le récepteur mannose-6-phosphate est possible. Cette dernière concernerait essentiellement la prorénine (dont les taux circulants sont 10 fois plus élevés que la rénine active). La suite de ce travail porterait sur la confirmation de cette hypothèse et l'identification de son possible rôle physiologique. SUMMARY The renin-angiotensin system is critical for the control of blood pressure and salt balance and other physiological and pathological processes. When blood pressure is too low, renin is secreted by the juxtaglomerular cells. It will cleave the N-terminus of circulating angiotensinogen (mostly secreted by the liver) to angiotensin-1, which is then transformed in angiotensin-II by the angiotensin-converting-enzyme (ACE). This system is regulated at the level of renin release. Renin, an aspartyl protease, is produced from a larger precursor (called prorenin) which is matured into active renin. Although the role of the renin proregion remains unknown, it has been reported that it could act as an autoinhibitor. Works on other proteolytic enzymes showed that their prorégion can act as chaperones. prorenin is the major circulating form of renin, while active renin represents only 10%. The enzyme which transforms, in vivo, the prorenin into active renin is unknown and the exact cleavage site remains to be elucidated. In this study, we generated some prorenin mutants, which were expressed in CV1 cells (constitutive pathway model) or AtT-20 cells (regulated pathway model). We showed that the proregion plays a pivotal role in the enzymatic activity and secretion of renin in a different manner in the two cell types. For the first time, it has been demonstrated that the proregion acts in an intermolecular way into the cell. Complementation assays showed that interaction between renin and proregion depends on the size of the proregion: prorenin (383 amino acids) > pro62 (62 amino acids) > pro43 (43 amino acids). Furthermore, our results showed that only a small amount of the cellular renin pool is targeted to the "canonical" regulated pathway and that the remaining is targeted to the lysosomes. Those results suggest a possible internalizátion of the circulating renin through the mannose-6-phosphate receptor pathway. This would mostly concern the prorenin (whose levels are ten times higher than active renin). Further studies would confirm or infirm this hypothesis and elucidate a potential physiological role.

The purpose of this Supplementary Report is to advise on how the budgetary measures impact on the conclusions in relation to tax credits and stamp duty included in the Authority’s November 2011 Report. in doing so, we will assess the direct impacts and we will discuss some scenarios. However, the Authority’s advice in this area relies on projections of the health insurance market and, in light of the above, there is considerable uncertainty surrounding any projections of how claims inflation or the market size may develop, even in the short and medium terms.
