The misdiagnosis of onychomycosis delays the proper treatment of the nail condition. Nail histomycology refers to the microscopic examination of histologic sections prepared from nail clippings for the purpose of detecting the presence of fungi. This laboratory method is the most sensitive procedure for the diagnosis of onychomycosis. It allows for the visualization of the precise location of the invasive fungus inside the nail apparatus. The method also distinguishes various shapes of the fungal cells, in particular filamentous fungi, yeasts, conidia, and sporodochia. The correct diagnosis provided by histomycology combined with culture not only allows for more efficient expenditure of funds and services but also is important for the timely alleviation of the disorder.

Adaptation to pregnancy involves major maternal anatomical, physiological and metabolic modifications to support the mother's metabolic needs and those of the growing foetus. Invasion of embryonic territories and implantation in humans and other mammals is the result of an active biochemical process. The invasive faculty of cytotrophoblastic cells depends on their capacity to secrete proteolytic enzymes such as matrix metalloproteinases (MMPs). Many studies have addressed the variations in MMPs in placental tissues, but few have reported on their measurements in plasma. Furthermore, the Pregnancy-Associated Glycoproteins (PAGs), which are synthesized in the syncytiotrophoblast and used as early markers of pregnancy in domestic and wild animals, have not yet been studied in rabbits. In this study, we attempt to purify PAGs from rabbit placenta using a previously described methodology and to measure their concentrations as well as those of MMP-2 and MMP-9 in the plasma throughout pregnancy. In the course of the work, we noted certain modifications of the biochemical parameters in plasma during gestation, essentially in glycemia and lipemia. We detected proteins immunologically-related to PAGs in placental extracts between D-14 to D-21. Until now, it has been impossible to develop a homologous RIA in order to measure PAGs in rabbit plasma, as the recovery of PAGs during the purification procedure was very low and PAGs were undetectable in rabbit plasma using heterologous RIAs. Finally, we demonstrated a rise in MMP-2 and -9 at the middle and the end of the gestation. However, the small variations presented by these matrix metalloproteinases preclude the use of plasma levels of these enzymes as early markers of pregnancy progress in the rabbit. [less ▲]

Facultative paedomorphosis is a polyphenism in which individuals may express one of two alternative ontogenetic pathways (metamorphosis vs. paedomorphosis) depending on environmental cues. Previous laboratory experiments showed that drying can cause morph ratio change, suggesting that the maintenance of facultative paedomorphosis is highly dependent on environmental determinants. The aim of this study was to examine seasonal variation in morph ratios in eight ponds from Larzac (southern France) naturally inhabited by palmate newts and to relate it to pond drying. in some ponds, the relative proportion of paedomorphs (i.e. individuals retaining gills at the adult stage) increased after the breeding period, but it remained stable or decreased in other ponds. This seasonal variation in the abundance of the two morphs most probably reflects (1) the emigration of metamorphs leaving the pond to occupy terrestrial habitats and (2) metamorphosis of paedomorphic adults in response to drying of the ponds. This study shows that facultative paedomorphosis in palmate newts is a dynamic process that allows rapid change (i.e. within a single year) in morph ratio to fit environmental variation (i.e. risk of drying) within the aquatic habitats. Long-term studies are needed to model the evolution of the dimorphism according to environmental change. (c) 2005 Elsevier SAS. All rights reserved. [less ▲]

In hydrogeology, advances in the delimitation of protection zones are made by the use of stochastic simulations integrating all available data. In practice, due to the few available measurements of the main parameters (hard data), it is very useful to integrate several secondary properties of the media as indirect data (soft data) to reduce the uncertainty of the results. In aquifers, most of the solute spreading is governed by the hydraulic conductivity (K) spatial variability, which is generally considered as the main uncertain parameter. A stochastic approach integrating hydraulic conductivity measurements (hard data), head observations and shallow electrical resistivity tomography (soft data) is presented. Results are discussed on a synthetic and on a practical case. It is shown in practice how the uncertainty of the well capture zone probability distribution (CaPD) can be reduced. Since geophysical data and head observations are easier to collect on the field then hydraulic conductivity measurements, they are generally more abundant. The methodology presented can even be used in real applications when little or no information is available about the hydraulic properties, through the conditioning on geophysical data and/or head observations.

The goal of this research is to propose an integrated approach to incorporate structural engineering concerns into architectural schematic designs for timely and well-informed decision making. This is done through a platform that is based on two software prototypes, EsQUIsE for capturing and interpreting architectural sketches, and StAr for assisting engineers during conceptual structural design. An integrated information model is provided for communication. Given the dissimilar “quality” of the information managed by both prototypes, sketch interpretation mechanisms are also required to “tune-up” communications for bringing the sketch to a precise structural engineering definition. As a result, the engineer can propose feasible structural systems earlier than usual. [less ▲]

The Hilbert transform is one of the most successful approaches to tracking the varying nature of vibration of a large class of nonlinear systems thanks to the extraction of backbone curves from experimental data. Because signals with multiple frequency components do not admit a well-behaved Hilbert transform, it is inherently limited to the analysis of single-degree-of-freedom systems. In this study, the joint application of the complexification-averaging method and the empirical mode decomposition enables us to develop a new technique, the slow-flow model identification method. Through numerical and experimental applications, we demonstrate that the proposed method is adequate for characterizing and identifying multi-degree-offreedom nonlinear systems. [less ▲]

Wind analysis of a structure subjected to non-linear random dynamic loading Since the early developments in wind engineering, aerodynamic coefficients have been linearized in turbulence analysis. On the other hand general and complex methods based on generalized power spectral densities can now handle this kind of non linearity. Between these two extremes, it would be desirable to give simple estimation of the effects of the non linearity of aerodynamic coefficients on the response of structures. This paper aims at giving an overview of these general and complex methodologies (that could be applied in other contexts), and, in a second step, presenting an original procedure to give estimation of the effects of the non linearity of aerodynamic coefficients. This procedure will be illustrated on the drag coefficient of the Viaduct of Millau [less ▲]

The political pressure in favour of multi- and inter-modal transport has oriented the focus on sustainable transport solutions. Inter-modal transport is one of the (partial) possible solutions, but its efficiency strongly depends on the places where the container terminals are located. The number of possible locations on large scale networks such as the European one becomes rapidly too large to be taken as input by exact location methods. That’s why the first goal of this paper is to outline a method that helps to identify the best potential locations out of the thousands of potential nodes. The basic idea is to use the flows of commodities and their geographic spreading as input to determine a set of good potential locations for transfer inter-modal terminals. This set can, in a second step, be used as input for already well known optimal location models in order to identify the optimal locations for container terminals in Europe. The complete methodology is illustrated by means on a case study that concerns multi-modal transport over the whole trans-European networks. [less ▲]
