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 ▲]

In the human and equine species, different kinds of free floating intra-articular particles are related to certain disorders. Osteochondral fragments formed during osteochondrosis dissecans are the most common finding in the equine species, whereas in humans rice bodies due to rheumatoid arthritis are more frequent. Herein we report a third type of floating body inside the stifle of an adult draught horse stallion, in macroscopic appearance similar to articular rice bodies known in humans. As revealed by histologic examination, the two particles consist of polypoid degenerated structures derived from synovial villi. Their formation was probably induced by ischemia. [less ▲]

Computer simulations of metal forming processes using the finite element method (FEM) are, today, well established. This form of simulation uses an increasing number of sophisticated geometrical and material models, relying on a certain number of input data, which are not always readily available. The aim of inverse problems, which will be considered here, is to determine one or more of the input data relating to these forming process simulations, thereby leading to a desired result. In this paper, we will focus on two categories of such inverse problems. The first category consists of parameter identification inverse problems. These involve evaluating the material parameters for material constitutive models that would lead to the most accurate results with respect to physical experiments, i.e. minimizing the difference between experimental results and FEM simulations. The second category consists of shape/process optimization inverse problems. These involve determining the initial geometry of the specimen and/or the shape of the forming tools, as well as some parameters of the process itself, in order to provide the desired final geometry after the forming process. These two categories of inverse problems can be formulated as optimization problems in a similar way, i.e. by using identical optimization algorithms. In this paper, we intend firstly to solve these two types of optimization problems by using different non-linear gradient based optimization methods and secondly to compare their efficiency and robustness in a variety of numerical applications.

The sesquiterpenoid juvenile hormone (JH) regulates insect development and reproduction. Most insects produce only one chemical form of JH, but the Lepidoptera produce four derivatives featuring ethyl branches. The biogenesis of these JHs requires the synthesis of ethyl-substituted farnesyl diphosphate (FPP) by FPP synthase (FPPS). To determine if there exist more than one lepidopteran FPPS, and whether one FPPS homolog is better adapted for binding the builder ethyl-branched substrates/products, we cloned three lepidopteran FPPS cDNAs, two from Choristoneura fumiferana and one from Pseudaletia unipuncta. Amino acid sequence comparisons among these and other eukaryotic FPPSs led to the recognition of two lepidopteran FPPS types. Type-I FPPSs display unique active site substitutions, including several in and near the first aspartaterich motif, whereas type-II proteins have a more "conventional" catalytic cavity. In a yeast assay, a Drosophila FPPS clone provided full complementation of an FPPS mutation, but lepidopteran FPPS clones of either type yielded only partial complementation, suggesting unusual catalytic features and/or requirements of these enzymes. Although a structural analysis of lepidopteran FPPS active sites suggested that type-I enzymes are better suited than type-II for generating ethyl-substituted products, a quantitative real-time PCR assessment of their relative abundance in insect tissues indicated that type-I expression is ubiquitous whereas that of type-II is essentially confined to the JH-producing glands, where its transcripts are ∼20 times more abundant than those of type-I. These results suggest that type-II FPPS plays a leading role in lepidopteran JH biosynthesis in spite of its apparently more conventional catalytic cavity [less ▲]

Les fictions télévisées, quand elles viennent à parler de police ou de justice, répondent à des codes, des règles, des schémas qui leur sont propres : si certains aspects de ces séries sont calqués assez fidèlement sur la réalité (par exemple, les personnages sont censés obéir à un corpus juridique), d'autres prennent plus de libertés, à divers degrés (de nombreuses conceptions relatives à la hiérarchie et à la déontologie ne sont appliquées que comme véhicules scénaristiques, ou sont simplement ignorés si l'histoire l'exige). Un élément que nous pourrions qualifier de plus accidentel est que beaucoup des séries favorites des téléspectateurs belges sont des programmes d'importation américaine. Même dans le cas où un scénariste américain aurait voulu coller de très près à la réalité et aux lois de son pays, il s'écartera en de nombreux points de notre système juridique, de par les fortes différences entre notre système (dit de droit civil) et le système anglo-saxon (dit de common law ou de case law). Les traductions et doublages français, parfois approximatifs – que les traductions soient mauvaises ou que certains termes ne disposent pas d'équivalents francophones parfaits – achèvent de créer la confusion. Partant de cette double constatation – la justice et la police romancées d'un côté et les problèmes de droit comparé et de traduction de l'autre –, j'en suis venue à me demander dans quelle mesure nos concitoyens transposaient ces situations au réel et les utilisaient comme « grille de compréhension » du fonctionnement de notre système judiciaire et policier.

Seven double-muscled Belgian Blue bulls (initial BW: 341 ± 21 kg) with cannulas in the rumen and proximal duodenum were used in an incomplete replicated Latin square. The study examined the effect of imbalance between energy and N in the rumen on microbial protein synthesis and N metabolism by giving the same diet according to 3 different feeding patterns. The feed ingredients of the diet were separated into 2 groups supplying the same amount of fermentable OM(FOM) but characterized by different levels of ruminally degradable N (RDN). The first group primarily provided energy for the ruminal microbes (12.5 g of RDN/kg of FOM), whereas the second provided greater N (33.3 g of RDN/kg of FOM). These 2 groups were fed to the bulls in different combinations with the aim of creating 3 levels of imbalance (0, 20, and 40 g/ kg of DM) between energy andN supplies in the rumen. Imbalance was measured by the variation of the degradable protein balance (OEB value in the Dutch system) of the diet between the 2 meals each a day. Diurnal variations in ruminal NH3-N concentrations and plasma urea concentrations were greatly influenced by the feeding patterns of the diet. Introduction of imbalance affected neither microbial N flow at the duodenum (P = 0.97) nor efficiency of growth (P = 0.54). The feeding patterns of the diet had no negative impact on NDF degradation in the rumen (P = 0.33). Nitrogen retention was not affected by imbalance (P = 0.74) and reached 49.7, 52.0, and 51.3 g/d, respectively for 0, 20, and 40 g of OEB/kg of DM imbalance. It seems that introduction of an imbalance between energy and N supplies for the ruminal microbes by altering the feeding pattern of the same diet does not negatively influence the microbial activity in the rumen norNretention of the animal. Nitrogen recycling in the rumen plays a major role in regulating the amount of ruminally available N and allows a continuous synchronization of N and energyyielding substrates for the microorganisms in the rumen. Therefore, imbalance between dietary energy and N created over a 24-h interval was not detrimental to rumen microbial growth for the animal as long as the level of imbalance did not exceed 40 g of OEB/kg of DM. Thus, these feeding patterns of the diet can be used under practical feeding conditions with minimal impact on the performance of ruminant animals for meat production. [less ▲]
