PET and PET-CT in Oncology describes the principles of positron emission tomography and is a useful resource for incorporating the technique in clinical practice. In a clear and straightforward fashion, this heavily-illustrated text offers instructive information and overviews of the basic principles of PET and PET-CT as well as the routine clinical PET scanning procedures for all important oncological indications. It is designed to serve as a reference work for specialists in nuclear medicine and radiology (including therapy planning) and for oncologists. It also provides student and physicians in other medical specialities with a general introduction to the effective integration of this modern technique into routine clinical diagnostics. Above all, this volume illustrates the importance of PET and PET-CT in comparison with other imaging techniques. [less ▲]

M. haemolytica serotype A1 (formerly known as Pasteurella) is the most important and commonly isolated bacterial pathogen from fatal cases of bovine fibrinous pleuroneumonia. M. haemolytica and its two principal toxins, the lipopolysaccharides (LPS) and the leukotoxin (LktA) induce the recruitment, the activation and the necrosis of neutrophils involved in the pathogenicity of bovine pneumonic mannheimiosis (BPM). The objective of this study was to determine whether systemic therapy with carprofène (Rimadyl®*), a non-steroidal anti-inflammatory drug, improves the disease development in an acute experimental model of BPM. The experimental pathology was induced by trans-tracheal inoculation of M. haemolytica and toxins at T0. One hour post-inoculation, six calves were treated intravenously with carprofen (1,4 mg/kg) while six placebo-treated calves received dose-matched volumes of sterile saline. The clinical and biochemical parameters were measured at one (T+1), three (T+3) and seven (T+7) hours after inoculation. Disease scores for carprofen treated calves were significantly lower than those for placebo-treated controls six hours (T+7) after treatment. These results were associated to a significantly oxygen saturation decrease at T+3 and a significantly blood lactate increase at T+7 in the control calves. Moreover, pulmonary lesions were significantly less extensive than those in the control group. Taken together, this finding suggest that pharmacological modulation by carprofen of pulmonary inflammation after appearance of acute BPM clinical signs leads to calves’ health enhancement and reduces the extent of gross pneumonic lesion.

Les Isomaltooligosaccharides (IMO) sont constitués de monomères de glucose liés par au moins une liaison α-1-6 (IMO classique), ou dans une moindre proportion α -1-3 (famille nigero-) ou α -1-2 (famille koji-). Ils sont produits par voie enzymatique à partir d’amidon de céréales hydrolysé. Un mélange très complexe est obtenu avec des molécules caractérisées à la fois par leur valeur de DP (de 2 à ~15), le type de liaisons en présence ainsi que la proportion et la position de chaque type de liaison (seules α -1-6 ou en combinaison). Le défi de cette étude est de trouver une méthode qualitative et quantitative pour caractériser ces sirops. Trois différentes méthodes ont été testées à l’aide de trois différents types de détecteur et comparées selon des critères de sélectivité, sensibilité, robustesse, applicabilité et de la faisabilité de l’analyse quantitative L’HPLC-RID (Refractive Index Detector) utilisée avec une colonne Prevail Carbohydrate (Alltech), adaptée aux sucres de DP variables, s’est révélée être peu sélective du fait de l’obligation de travailler en conditions isocratiques. L’HPLC-ELSD (Evaporating Light Scattering Detector) permettant de travailler en gradient d’élution, une très bonne séparation des différents DP est obtenue sur la même colonne ainsi qu’une séparation des différents DP2 et une amélioration de la sensibilité. L’analyse quantitative reste plus délicate du fait de la zone relativement limitée de linéarité. La Chromatographie à Echange d’Anion et à Haute performance couplée à la Détection à Amperometrie Pulsée (HPAEC-PAD), une séparation hautement sélective et une détection très sensible. Elle est une des seules méthode capable de séparer des molécules homologues ayant comme seules différences leur DP ou de leur type et la séquence de leurs liaisons. L’analyse quantitative a fait l’objet d’une étude approfondie, les facteur de réponses étant dépendant de la structure, du DP et du type de liaisons des oligosaccharides. [less ▲]

Strained silicon on insulators (sSOI) wafers with a supercritical thickness of 58 nm were produced using thin strain relaxed SiGe buffer layers, wafer bonding, selective etch back and epitaxial overgrowth. Raman spectroscopy revealed an homogeneous strain of 0.63 plusmn 0.03 % in the strained Si layer. Long channel n-type SOI-MOSFETs showed very large electron mobilities up to 1200 cm2/Vs in the strained Si devices. These values are more than two times larger than those of reference SOI n-MOSFETs. Mobility simulations with state of the art scattering models are then used to interpret the experiments. [less ▲]

We study passive and nonlinear targeted energy transfers induced by resonant interactions between a singledegree- of-freedom nonlinear energy sink (NES) and a 2-DOF in-flow rigid wing model. We show that it is feasible to partially or even completely suppress aeroelastic instability by passively transferring vibration energy from the wing to the NES in a one-way irreversible fashion. Moreover, this instability suppression is performed by partially or completely eliminating its triggering mechanism. Numerical parametric studies identify three main mechanisms for suppressing aeroelastic instability: recurring burstout and suppression, intermediate suppression, and complete elimination.Weinvestigate these mechanisms both numerically by the Hilbert–Huang transform and analytically by a complexification-averaging technique. Each suppression mechanism involves strong 1:1 resonance capture during which the NES absorbs and dissipates a significant portion of energy fed from the flow to the wing. Failure of suppression is associated with restoring the underlying triggering mechanism of instability, which is a series of superharmonic resonance captures followed by escapes from resonance. Finally, using a numerical continuation technique, we perform a bifurcation analysis to examine sensitive dependence on initial conditions and thus robustness of instability suppression. [less ▲]

Background: With the improvements in biosensors and high-throughput image acquisition technologies, life science laboratories are able to perform an increasing number of experiments that involve the generation of a large amount of images at different imaging modalities/scales. It stresses the need for computer vision methods that automate image classification tasks. Results: We illustrate the potential of our image classification method in cell biology by evaluating it on four datasets of images related to protein distributions or subcellular localizations, and red-blood cell shapes. Accuracy results are quite good without any specific pre-processing neither domain knowledge incorporation. The method is implemented in Java and available upon request for evaluation and research purpose. Conclusion: Our method is directly applicable to any image classification problems. We foresee the use of this automatic approach as a baseline method and first try on various biological image classification problems. [less ▲]

A characteristic of incremental sheet metal forming is that much higher deformations can be achieved than conventional forming limits. In this paper it is investigated to which extent the highly non-monotonic strain paths during such a process may be responsible for this high formability. A Marciniak-Kuczynski (MK) model is used to predict the onset of necking of a sheet subjected to the strain paths obtained by finite-element simulations. The predicted forming limits are considerably higher than for monotonic loading, but still lower than the experimental ones. This discrepancy is attributed to the strain gradient over the sheet thickness, which is not taken into account in the currently used MK model. [less ▲]

BACKGROUND: The observation of photo-exposed skin under ultraviolet light reveals a mosaic pattern of varying intensity in epidermal melanization. Several patterns of mosaic subclinical melanoderma (MSM) have been described using a specially designed CCD camera and the ultraviolet light-enhanced visualization (ULEV) method. Vitamin D(3) and its analogues influence the biology of keratinocytes and melanocytes. OBJECTIVE: To assess the effect of calcipotriol on MSM. METHODS: This randomized split-face study was conducted in 27 men to compare the effect of once daily applications of 5% calcipotriol cream or a moisturizing cream on the heterogeneity of facial MSM. Computerized image analysis of video images was used at 1-month intervals before and during a 2-month treatment, as well as during a 3-month follow-up. RESULTS: At both sites, the average melanin content of the epidermis showed no significant change over time. However, the mottled appearance was smoothened at the calcipotriol site, whereas it was increased at the site receiving the moisturizer. CONCLUSION: The decreased heterogeneity in MSM after calcipotriol applications suggests a control of the epidermal melanocyte unit by the vitamin D(3) derivative. [less ▲]
