The implementation of the Water Framework Directive (EU 2000) requires a groundwater quality monitoring. It is used for characterisation of the 'good' chemical status of each groundwater body and for the restoration or protection purposes of those bodies already at 'good' status. Interpretative aspects are lying in the design of monitoring network and in the way of building global indicators. Attention is given here to the global chemical status of the groundwater bodies and to the role of diffuse pollution, much of which is brought via groundwater to surface water. Monitoring 'local' pollution associated with individual sites is not addressed. Groundwater bodies with different contrasted hydrogeology conditions, land use and topography have been considered to establish an approach for choosing an optimised monitoring network. Then, a quality assessment system has been developed and applied for qualifying the general status of each groundwater body. The use of non-dimensional indexes allows us to process with all kinds of chemical parameters in a normalised way and, by means of adequate aggregation rules, to qualify the general quality status of a groundwater body. The obtained diagnostic, even if not fully validated, is closely linked to the pragmatic objectives contained in the EU Water Directive. [less ▲]

We report on the magnetic field evolution of the Neel temperature T-N in the heavy electron system CeIn3-xSnx (x = 0 and 0.3), as determined by specific heat, magnetocaloric effect, and electrical transport measurements. For the stoichiometric compound, T-N is fully suppressed at H-c similar to 65 T, whereas for x = 0.3 the critical field extrapolates to H-c similar to 30 T. An increasing Sommerfeld coefficient gamma, obtained above T-N, as field increases is observed and could be related to the a putative quantum critical point at H-c.

Idiopathic canine eosinophilic bronchopneumopathy (EBP) is a disease characterized by eosinophilic infiltration of the pulmonary interstitium and bronchial mucosa, a cause for which has not yet been discovered. A recent study, examining the relative proportion of various lymphocyte cell subsets within bronchoalveolar lavage fluid from dogs with EBP, has shown a selective increase in CD4(+) T-cells and a selective decrease in CD8(+) T-cells, suggesting that a similar Th2 immune response might occur in EBP. The aim of the present study was to determine the profile of cytokine, chemokine and CC chemokine receptor 3 (CCR3) messenger RNA (mRNA) expression in bronchial tissue from dogs with EBP. Real-time RT-PCR assays were used for the quantification of mRNA encoding for a panel of cytokines, CC chemokines and CCR3 in perendoscopic bronchial biopsies from eight dogs with EBP and seven age-matched control dogs. Messenger RNA transcribed from the housekeeping gene glyceraldehyde-3 -phosphate dehydrogenase was used for normalisation of the threshold cycle in order to determine the relative copy numbers of the transcripts. No significant difference in the expression of any cytokine, MCP-1, -2, -4 and CCR3 was found between control and EBP dogs. The expression of transcript for MCP-3, eotaxin-2 and -3 was significantly greater in bronchial biopsies from dogs with EBP than in samples from control dogs while there was significantly less mRNA encoding RANTES in the mucosa of dogs with EBP. In conclusion, the cytokine mRNA expression profile in perendoscopic bronchial biopsies is similar in dogs with EBP and dogs without respiratory disease. Further studies on the quantification of mRNA encoding cytokines in isolated T lymphocytes from bronchoalveolar lavage fluid or bronchial biopsies are needed before any conclusion on the cytokine profile in canine EBP can be drawn. Eotaxin-2, -3 and MCP-3 appear to be implicated in the pathogenesis of the disease. (c) 2005 Elsevier B.V. All rights reserved. [less ▲]

Behavioural responses of sea bass Dicentrarchus labrax were investigated after exposure to cadmium ions in laboratory-controlled conditions. The aim of this study was to discover whether environmental exposure to cadmium ions inactivates fish lateral line system neuromasts, and to determine the behavioural consequences of such a sensory blockage. For this, fish escape behaviour in response to an artificial water jet was recorded using a 25-frames s(-1) analog video camera before and after cadmium exposure. Experimental set up was tested with fish whose lateral line system was artificially inactivated by antibiotics (gentamicin and streptomycin). Histological analyses with scanning electron microscopy showed antibiotic treatment destroyed lateral line system neuromasts. In addition, these fish did not respond to stimulations provoked by the water jet after antibiotic treatment. Fish escape behaviour was then recorded before and after cadmium exposure at two different concentrations. When fish were exposed to the first concentration of cadmium tested (0.5 microg l(-1), which represents the maximal cadmium concentration encountered in contaminated estuaries), no alteration in neuromast tissue was observed. In addition, before cadmium exposure, fish responded positively in 98.41 +/- 4.95% of lateral line system stimulations (escape behaviour in response to the water jet). After cadmium exposure, no behavioural modification could be detected: the fish responded positively in 95.16 +/- 9.79% of stimulations (chi(2) = 2.464, p = 0.116). In contrast, the high cadmium concentration used (5 microg l(-1), which represents 10 times the concentration occurring in highly polluted estuarine areas) involved severe neuromast tissue damage. Just after such cadmium exposure, fish showed only 41.67 +/- 35.36% of positive responses to their lateral line system stimulations, while they responded positively in 95.93 +/- 9.10% of stimulations under control conditions (chi(2) = 24.562, p < 0.0001). Their lateral line system neuromasts seemed to regenerate about 1 month after cadmium exposure. Associated with this regeneration, from the 21st day after cadmium exposure, their escape behaviour had recovered and was not significantly different from that recorded under control conditions (86.74 +/- 20.82%, chi(2) = 2.876, p = 0.090). This study shows that although 5 microg l(-1) cadmium is able to damage lateral line system neuromasts and causes fish behavioural alterations, fish exposed to 0.5 microg l(-1) cadmium displayed neither tissue neuromast nor behavioural modification.

Recent studies have shown that the T 2 control chart with variable sampling intervals (VSI) and/or variable sample sizes (VSS) detects process shitis faster than the traditional T 2 chart. This article extends these studies for processes that are monitored with VSI and VSS using double warning lines ( T 2 - DWL ). It is assumed that the length of time the process remains in control has exponential distribution. The properties of T 2- DWL chart are obtained using Markov chains. The results show that the T 2 - DWL chart is quicker than VSI and/or VSS charts in detecting almost all shifts in the process mean. [less ▲]

BACKGROUND: In various connective tissue disorders, collagen fibrils and elastic fibers may exhibit some ultrastructural abnormalities. OBJECTIVE: This electron microscopy study focused on collagen fibril orientation and unusual shapes in the dermis of Ehlers-Danlos syndrome (EDS) and related entities, including spontaneous cervical artery dissection syndrome and recurrent preterm premature rupture of fetal membranes syndrome. RESULTS: In addition to some abnormal fibril shapes typically found in these syndromes, other conformations (hook shaped, S shaped, ring shaped) that have not been illustrated previously in the literature were observed. CONCLUSION: The abnormal collagen fibril conformations observed in EDS and other related conditions characterized by tissue fragility likely affect both the internal cohesiveness of the bundles and the mechanobiologic properties of the tissue.

Specimens of the pearlfish Carapus mourlani (Carapidae) were observed for the first time in association with the sea cucumber Isostichopus fuscus (Holothuroidea: Echinodermata) along the coast of Ecuador. Out of 4345 sea cucumbers collected from various depths between 5 and 60 m, 12 harbored a pearlfish either in the coelomic cavity, the respiratory tree, or the digestive tract, yielding a prevalence of ca. 0.0028. The presence of C. mourlani appeared to be detrimental to the holothurian host in some cases. Side effects resulting from coelomic cavity infections included less advanced gonad maturity (reduced gonadal tubule diameter and length, lower ratio of mature oocytes) and a significant proportion of necrotic and shriveled gonadal tubules, devoid of gametes. Aside from discussing this evidence, the present paper briefly describes the biology of the pearlfish, its relationship with the host, and its daily activity cycle. [less ▲]

Rapid eye movement sleep (REMS) is associated with intense neuronal activity, rapid eye movements, muscular atonia and dreaming. Another important feature in REMS is the instability in autonomic, especially in cardiovascular regulation. The neural mechanisms underpinning the variability in heart rate (VHR) during REMS are not known in detail, especially in humans. During wakefulness, the right insula has frequently been reported as involved in cardiovascular regulation but this might not be the case during REMS. We aimed at characterizing the neural correlates of VHR during REMS as compared to wakefulness and to slow wave sleep (SWS), the other main component of human sleep, in normal young adults, based on the statistical analysis of a set of (H2O)-O-15 positron emission tomography (PET) sleep data acquired during SWS, REMS and wakefulness. The results showed that VHR correlated more tightly during REMS than during wakefulness with the rCBF in the right amygdaloid complex. Moreover, we assessed whether functional relationships between amygdala and any brain area changed depending the state of vigilance. Only the activity within in the insula was found to covary with the amygdala, significantly more tightly during wakefulness than during REMS in relation to the VHR. The functional connectivity between the amygdala and the insular cortex, two brain areas involved in cardiovascular regulation, differs significantly in REMS as compared to wakefulness. This suggests a functional reorganization of central cardiovascular regulation during REMS. (c) 2006 Elsevier Inc. All rights reserved. [less ▲]
