We comment on some points about the coding of stochastic processes by sequences of independent random variables. The most interesting question has to do with the standardness property of the filtration generated by the process, in the framework of Vershik's theory of filtrations. Non-standardness indicates the presence of long memory in a purely probabilistic sense. We aim to provide a short, non-technical presentation of Vershik's theory of filtrations. [less ▲]

This article concentrates on the disputes born from de redaction followed by the publication of a little theology handbook entitled “Instructio ad tyronem” (1672). Work of a Canon of Gent, Peter van Buscum, it causes passionate reactions in the Low Countries because it questions the possibility of a dogmatic definition of the Immaculate Conception. The A. shows how two clans confront each other. The first group comprises some theologians and priests trained in the Louvain University to the positive theology. They promote, from a theological as well as religious point of view, a moderate and rigorous behaviour, invoking the obligation of fidelity to the scriptural and patristic sources. The others (Eugène-Albert d’Allamont, Gent’s Bishop, Carlo Francesco Airoldi, internuncio, Mendicants and Jesuits) are the defenders of Rome. They sustain some demonstrative worship forms, sometimes ostentatious. The one and the others weren’t able to get along. Their opposition manifested itself around the “Instructio”. [less ▲]

OBJECTIVES: The treatment of brain tumors in childhood is frequently complicated by growth retardation with a high proportion of irradiation (Irr)-induced GH deficiency (GHD) resulting in reduced adult final height (AFH) even after GH therapy (GHT). In order to optimize future GHT protocols, more information on the factors influencing the growth response to GH in these children is needed. This retrospective study evaluated AFH and influencing auxological and treatment factors of a standardized daily biosynthetic GHT in childhood survivors of brain tumors with documented GHD after brain Irr. DESIGN AND METHODS: From the Belgian GH Registry, 57 children survivors of a brain tumor outside the hypothalamo-pituitary area with available AFH were stratified into two groups depending on cranial (C-Irr; n=25) or craniospinal (CS-Irr; n=32) Irr. RESULTS: In the C-Irr patients, results showed an AFH of -0.8 (-2.5, 1.4) SDS (median (range)) and in the CS-Irr patients, results showed a significantly (P<0.001) lower AFH of -1.8 (-4.2, 0.0) SDS. AFH SDS corrected for mid-parental height (MPH) in the C-Irr group was -0.5 (-2.2, 0.9) and -1.5 (-3.6, 0.0) SDS in the CS-Irr group. AFH was positively correlated with age at end of tumor therapy, height SDS at start GHT, height gain SDS first year GHT, and negatively correlated with CS-Irr. CONCLUSIONS: GHT failed to restore adult height to MPH in nearly half of Irr-induced GHD patients for brain tumor, especially those receiving CS-Irr, irradiated at a younger age or shorter at start GHT.

Thanks to their photosynthetic and nutritive properties, cyanobacteria of the Arthrospira genus are of interest as food supplements, as efficient oxygen producing life support system organisms for manned space flight, and for the production of biofuels. Despite these potential valuable applications, full genome sequences and genetic information in general on Arthrospira remain scarce. This is mainly due to the difficulty to extract sufficient high molecular weight nucleic acids from these filamentous cyanobacteria. In this article, an efficient and reproducible DNA extraction procedure for cyanobacteria of the genus Arthrospira was developed. The method is based on the combination of a soft mechanical lysis with enzymatic disruption of the cell wall. The comparison with other extraction protocols clearly indicates that this optimised method allows the recovery of a larger amount of DNA. Furthermore, the extracted DNA presents a high molecular weight, a reduced degradation and an excellent overall quality. It can be directly used for molecular biology purposes such as PCR, and clone library construction. [less ▲]

Reversible protein phosphorylation is a major intracellular mechanism for controlling many important physiological activities. In the past, most of the attention was focused primarily on protein kinases and on their regulation, mainly because phosphatases were then viewed as simple housekeeping enzymes. But advances in the understanding of phosphatases make now clear that protein phosphatases are dynamic and highly regulated enzymes and are as important as kinases in the regulation of cellular processes involving protein phosphorylation. Protein phosphatase 2A (PP2A) is a very abundant -it accounts for as much as 1% of total cellular protein-, ubiquitous and remarkably conserved enzyme. By dephosphorylating a plethora of cellular proteins, it is involved in the regulation of nearly all cellular activities. [less ▲]

Le Soleil est à l’origine de la vie sur Terre. Le grand ensemble d’interactions biogéochimiques entre la vie, le sol, l’atmosphère et l’océan n’est pas sans rappeler la physiologie d’un grand organisme unique. Ce dernier a reçu le nom de Gaïa. Tout le fonctionnement de la biosphère qui en fait partie est largement dépendant de l’apport énergétique solaire. Celui-ci est diversifié car le spectre des rayonnements électromagnétiques est large et variable en intensité et en nature. Le réchauffement global de la Terre et le « trou d’ozone » sont sous les feux de l’actualité. De tels bouleversements sont-ils la préfiguration d’une apocalypse ? L’écologie et la dérive géoclimatique vont-elles influencer la dermatologie de demain ? [less ▲]

Le sujet adulte d’âge moyen en surpoids ou obèse est caractérisé par une adiposité exagérée, généralement combinée à une aptitude physique cardio-respiratoire déficiente. La pratique régulière d’une activité physique d’endurance améliore le profil de risque cardio-métabolique dans cette tranche d’âge. Le manque d’activité physique chez les adolescents contribue à augmenter leur masse grasse et à induire des anomalies métaboliques, tandis que la sédentarité marquée des sujets âgés peut conduire à un excès de graisse combiné à une fonte musculaire (obésité sarcopénique). Dans ces deux tranches d’âge, les effets néfastes d’un excès de masse grasse (fatness) pourraient être contrecarrés, voire annulés, par la pratique régulière d’exercices musculaires conduisant à une meilleure aptitude physique (fitness). Cet article décrit les relations entre fitness et fatness, et les impacts cardio-métaboliques respectifs de ces deux composantes, d’une part, dans la population jeune (< 20 ans), d’autre part dans la population âgée (> 60 ans).

Olfactory signals play an important role so that breeding efforts are synchronized with appropriate social and environmental circumstances. In this context, the mammalian olfactory system is characterized by the existence of several olfactory subsystems that have evolved to process olfactory information. While the vomeronasal (or accessory) olfactory system is usually conceived as being involved in the processing of pheromonal signals due to its close connections with the reproductive hypothalamus, the main olfactory system is, by contrast, considered as a general analyzer of volatile chemosignals, especially those that are used for the social identification of conspecifics. In fact, several recent sets of experiments suggest that both the main and accessory olfactory systems have the ability to process partly overlapping pheromonal chemosignals and that both systems converge at a downstream level of pheromonal processing. As a consequence, both systems have the ability to support complimentary aspects in mate discrimination and sexual behavior. However, the relative roles played by these systems and their interactions are at present still far from being understood. [less ▲]
