BACKGROUND: Corynebacterium spp. are diphtheroid bacteria responsible for pitted keratolysis, a common plantar infection confined to the thick stratum corneum. AIM: To study a series of demographic features of patients suffering from pitted keratolysis, and to present a review of the Corynebacterium-associated infections, including pitted keratolysis, erythrasma, and trichobacteriosis. MATERIALS AND METHODS: A 2-year, two-center, prospective survey assessed the demographics of pitted keratolysis, including age, gender, site of infection, symptoms, patients' complaints, the use of protective and/or occlusive shoes, seasonality of diagnosis, drug intake, associated skin signs (including dyshidrosis, erythrasma, and trichobacteriosis), recurrences, and previous diagnoses and treatments. RESULTS: The mean age of the 53 patients with pitted keratolysis was 24.9 years (range, 10-57 years). The male to female ratio was 7.8:1. The soles of both feet were commonly involved (92.4%). Pressure-bearing areas were the usual sites of infection, ranging from restricted involvement of the toes (12/53, 22.6%) to spreading to the entire plantar surface (15/53, 28.3%). A total of 36 (68%) of the 53 patients complained of hyperhidrosis. An unpleasant smell and pain were noted by 35 (66%) and 25 (47%) of the 53 patients, respectively. Occlusive and protective shoes were worn in 51 (96.2%) and 31 (58.4%) of the 53 cases, respectively. CONCLUSION: Pitted keratolysis commonly affects young male patients wearing protective shoes for professional reasons, inducing a moist and warm environment. Hyperhidrosis, an unpleasant smell, and pain are the main clinical complaints. [less ▲]

Four brachiopod species from the upper Givetian of Ferques are described of which two are new: Cupularostrum minimum n. sp. (Rhynchonellida) and Cleiothyridina blacourti n. sp. (Athyridida). The third, which is assigned to Stringocephalus aff. fontanus Veevers, 1959, corresponds after revision to S. sp. (in Brice & Loones 2002) pro parte. The fourth is Stringodiscus giganteus (Sowerby, 1840) which is recorded for the first time in France. Material originates mainly from the Couderousse Member of the Blacourt Formation, dated by conodonts from the “Middle-Upper varcus Zone”, but exclusively for S. aff. fontanus and St. giganteus. Some rare specimens of C. minimum and Cl. blacourti have been collected in the lower part of the Bastien Member, upper part of the Blacourt Formation. Cl. blacourti is very common in the upper Givetian of Ferques, so the genus Cleiothyridina appears as soon as the upper Givetian as in Spain and not in the Famennian as it is reported in the “Treatise revised” (Alvarez & Rong, 2002).

The mouthbrooding cichlid Oreochromis niloticus is one of the world’s best-studied fish and is raised extensively for aquaculture. Although it is a common behavioural model, its acoustic communication has been neglected. Because of extensive parental care, the species is a good candidate for vocal learning. In male O. niloticus, we investigated for the first time sound production in agonistic interactions during nest construction. Males produce short-duration (250– 400 ms), often double-pulse sounds. Most energy is below 200 Hz and includes three main low-frequency peaks although energy extends beyond 1 kHz. Males (separated as eggs and raised in isolation) produce similar sounds in the same context as parental fish, indicating that the ability to produce sounds and the basic properties of the sounds are innate.

The quality valuation of wheat is based on characteristics like yield, specific weight, protein content and protein quality. Until now. the starch properties are rarely considered as a quality criterion. In this study, we showed the influence of wheat cultivars (Triticum aestivum L.) and culture year on the intrinsic properties of starch, extracted from European wheat grown in the same conditions. For example, starch damage varied from 13.2 to 19.9 CDU in function of the cultivars and contribution of the B-type starch granules (<10 mu m) to the total volume ranged from 11.6% to 29.9%. Starch viscosity at 95 degrees C, characterized with alpha-amylase inactivation by 2 mM AgNO3 addition. varied from 276.5 to 351.5 BU with the wheat cultivars. It is apparent from this study that starch properties were principally influenced by the wheat cultivar and slightly by the culture year. A good relationship between the pasting properties of whole flour and starch were finally established, showing the important role of starch in the whole flour viscosity. A thorough working knowledge of starch properties could lead to an appropriate selection of wheat cultivar, well-adapted to industrial end uses, without encountering processing or end-products quality problems and with most cost-competitive production.

Aias, herausragender griechischer Heros vor Troia, metzelt im Zustand der Raserei Herdenvieh nieder, in dem er seine Gegner zu erkennen glaubt. Zur Besinnung gekommen, stürzt er sich, beschämt über den Ehrverlust, in sein Schwert. Die ‚Entschuldigung‘, die für Aias nur durch Entleibung zu leisten war, entspricht heute etwa dem medial inszenierten Rückzug aus der politischen Öffentlichkeit, dem Rücktrittsangebot oder dem Fehlereingeständnis. Offensichtlich gibt es nach wie vor ein kollektives Bedürfnis nach solchen stellvertretenden Reinigungsritualen. Anlässe und Reaktionsformen haben sich zwar gewandelt, das Gefühl der Scham aber ist immer noch von existenziell-individueller Bedeutung und besitzt eine öffentlich wirksame Symbolik. Historisch gesehen spannt der Band einen Bogen von der (laut Georg Wilhelm Friedrich Hegel) ‚gewissenlosen‘ griechischen Antike bis in die ‚unverschämte‘ Gegenwart. Systematisch betrachtet konfrontieren die unterschiedlichen Kulturkreise einander in ihren Definitionen und Kompensationen von Fehlverhalten: vom paganen Griechentum über das christliche Abendland bis hin zum Islam. Im 20. und 21. Jahrhundert bestimmen Diskurse der Bewältigung den Umgang mit der Geschichte, mit Fragen der Kriegsschuld oder des Völkermordes. Kulturelle, nationale, historische und gender-spezifische Unterschiede prägen die verbalen Entschuldigungen, das öffentliche und private Verhalten, Kleidercode und Körpersprache. Während Schamdiskurse dazu dienen, eigenes Fehlverhalten in der Gemeinschaft zu regulieren oder vor dem Selbst zu rechtfertigen, funktionieren umgekehrt Schuldzuschreibungen oder gezielte Beschämungen des anderen als Herrschaftsinstrumente: prominent etwa in den Bildern von Abu Ghraib.

The main purpose of the present paper is to describe and discuss the development, validation and application of a numerical model designed to handle transient flows with high sediment transport rates. The model considers non-equilibrium transport (i.e. accounting for loading / unloading delay) and is numerically as well as physically totally coupled. The closure relations needed to evaluate the exchange fluxes between the fixed bottom and the flowing mixture (erosion and deposition rates) are also detailed in the paper. Finally, the model is validated against experimental data collected in the framework of the European project IMPACT. [less ▲]

La GFP permet de voir les protéines directement dans les organismes vivants, de les localiser grâce à la fluorescence qu’elle émet. Par manipulation génétique, on peut accrocher la GFP à diverses protéines que l’on peut ainsi suivre à la trace dans les cellules en fonctionnement. Comme une large variété de mutants de la GFP émettant des fluorescences de couleurs différentes sont disponibles, on peut même localiser plusieurs protéines simultanément.

The present thesis is concerned with the issues involved in obtaining reliable experimental data permitting a retrospective assessment of radiation-induced doses at the time of application or contamination. In order to provide prompt medical treatment of those injured in accidents with ionizing radiation, biological procedures that can be implemented swiftly and at an early stage are required both to determine the radiation dose originally received as well as to assess the course of the dose-dependent biological reactions on the basis of individual sensitivity to radiation. To this end, in the present thesis the lymphocyte proteins (phosphoproteins and total proteins) in blood taken from test subjects who had been exposed to γ-radiation (applied dose: 0-4 Gy) were analysed just 15 minutes after completing irradiation by means of 2D gel electrophoresis. Only those early-response proteins (ERPROs) that displayed a significant radiation-induced change were identified by nano-HPLC-MS/MS. For validation purposes, the dose-dependent gene expression of some of these proteins was determined by RT-qPCR. The following ERPROs displayed pronounced early reactions in the form of changes of concentration in comparison to unirradiated control samples: talin-1, talin-2, β-actin, mutant β-actin, peroxin-1 and also the phosphoproteins annexin-A6, MHC-binding protein-2, zyxin-2, interleukin-17E and phosphoglycerate kinase-1. The majority of the lymphocyte ERPROs represent proteins responsible for changes to the cytoskeleton, proliferation and cell cycle, modulation of immunoreactions as well as protein degradation and energy production. Other cellular processes may not have been determined due to the sensitivity restrictions of the 2D-PAGE and MS methods, but cannot be excluded. Gene expression studies revealed that a combination of methods, comprising RT-qPCR and 2D-PAGE as well as DNA microarray and Western blot, may in future be able to overcome these restrictions. The slopes of the curves from concentration measurements of various early response proteins after doses had been applied in the 0 and 4 Gy range yielded a characteristic arrangement or pattern representative of an individual. In case of contamination, this pattern prepared ex vivo serves as a reference for identifying the originally unknown dose, thus creating the necessary condition for applying an individual radiation biodosimeter. This thus provides for the first time an experimental means of biologically quantifying in retrospect radioactive doses in the 0 and 4 Gy range after a relatively short time. [less ▲]

Due to their kinetic and substrate specificities, triacylglycerol acyl-hydrolases or lipases are atypical enzymes. In function of their microenvironment, lipases are able to act as hydrolases in aqueous solution or as biocatalysts in organic synthesis. As hydrolases, they are responsible of the triglycerids catabolism into fatty acids and glycerol. In many organisms, this reaction plays a major role in the fat and lipid metabolism. In addition, lipases are also able to hydrolyse phospholipids and cholesterol esters. In organic solvent, lipases could catalyse reactions such as esterifications, acidolysis or alcoolysis with enantio-, regio- and chimioselectivity. Lipases form a mixed class of enzyme due to their animal, vegetal or microbial origins. All those properties led to the development of many applications in the food and chemical industries but also in the medical and therapeutic field. [less ▲]
