Disorders of the phosphocalcic metabolism are frequent in dialysis patients. Such disorders are difficult to treat and have negative impact on bone health, but also on cardiovascular mortality. Hyperphosphoremia is a strong predictor of cardiovascular mortality. New phosphate binders are now available in Belgium. A new molecule acting on the calcium receptor of the parathyroid glands is able to control secondary and tertiary hyperparathyroidism in dialysis patients. These new therapies, specific for dialysis patients, will be reviewed in this article. [less ▲]

Theoretical and experimental suppression of aeroelastic instabilities by means of broadband passive targeted energy transfers has been recently studied. A single-degree-offreedom (SDOF) nonlinear energy sink (NES) was coupled to a 2-DOF rigid wing modeled in the low-speed, subsonic regime with quasi-steady aerodynamic theory. The nonlinear attachment was designed and optimized to suppress the critical nonlinear modal energy exchanges between the flow and the (pitch and heave) wing modes, thus suppressing the (transient) triggering mechanism of aeroelastic instability. We performed bifurcation analysis to find regions of robust passive aeroelastic suppression in parameter space. Then, we employed multi-degreeof-freedom nonlinear energy sinks (MDOF NESs) to improve robustness of the aeroelastic instability suppression. Bifurcation analysis by a numerical continuation technique demonstrated that controlling the occurrence of a limit point cycle (LPC or saddle-node) bifurcation point above a Hopf bifurcation point is crucial to enhancing suppression robustness. MDOF NESs not only can enhance robustness of suppression against even strong gust-like disturbances, but they require lower NES mass compared to SDOF NES designs. The validity of the theoretical findings was proven by a series of wind tunnel experiments. [less ▲]

Self-assembly of p-benzenedimethanethiol (p-BDMT) on Pt(111) has been investigated by high-resolution electron energy loss spectroscopy and sum-frequency generation spectroscopy. The molecules adsorb on Pt-(111) like on gold, attached through one single thiol, leaving the second thiol moiety unreacted and exposed to the outer surface. Yet, the order of the p-BDMT self-assembled film is poor in comparison to alkanethiol SAMs. Displacement in solution of a preadsorbed pentanethiol (PTT) SAM by p-BDMT molecules proved to be a successful approach to achieve films of higher quality, where the size of the dithiol molecular domains tends toward the size measured for PTT. Nearly complete exchange is accomplished after 42 h. However, no significant exchange is observed when dodecanethiol replaces PTT. Displacing the alkanethiols by benzenethiol leads to the same conclusions, suggesting that the exchange processes are lessened as compared to gold. [less ▲]

Long-term outcomes (mean 38+/-17 months) were evaluated in 27 dogs with sinonasal aspergillosis after successful medical treatment using intranasal infusions of 1% or 2% enilconazole (1%, n=15; 2%, n=12). Long-term outcomes with both treatment protocols were good, with half of the dogs being asymptomatic throughout the follow-up period. The remaining dogs showed mild clinical signs compatible with chronic rhinitis/sinusitis. These clinical signs were interpreted as chronic lymphoplasmacytic rhinitis/sinusitis and episodes of bacterial rather than fungal infection. Three dogs had confirmed reinfection or relapse 2 to 36 months after clinical resolution [less ▲]

The bi-axial experimental equipment [Flores, P., Rondia, E., Habraken, A.M., 2005a. Development of an experimental equipment for the identification of constitutive laws (Special Issue). International Journal of Forming Processes] developed by Flores enables to perform Bauschinger shear tests and successive or simultaneous simple shear tests and plane strain tests. Flores investigates the material behavior with the help of classical tensile tests and the ones performed in his bi-axial machine in order to identify the yield locus and the hardening model. With tests performed on one steel grade, the methods applied to identify classical yield surfaces such as [Hill, R., 1948. A theory of the yielding and plastic flow of anisotropic materials.

Comparison with the Taylor–Bishop–Hill yield locus is also provided. The effect of both yield locus and hardening model choices is presented for two applications: plane strain tensile test and Single Point Incremental Forming (SPIF). [less ▲]

The Pomacentridae, commonly known as damselfishes, is one of the most specious families of coral reef fishes (>350 species). The genus Dascyllus contains ten species which are fall into three complexes: the aruanus, reticulatus and trimaculatus. The members of the two first complexes are small-bodied with a maximum standard length (SL) of 50-65 mm and the third complex groups large-bodied fishes of 90-110 mm SL. Phylogenetic data place the aruanus complex in a basal position with the two other species groups as derived sister taxa. Herein, we test the hypothesis that evolutionary change throughout the large-bodied species occurs by isometry. Geometric morphometrics is used to examine the ontogeny of size and shape. This method, which allows description and statistical analysis of form, is applied for the neurocranium and mandible in the three species referencing each complex: Dascyllus aruanus, D. reticulatus and D. trimaculatus. Another closely related pomacentrid, Chromis viridis, was used as outgroup for comparing ontogeny. At the larval stage, the structures are rather similar. Multivariate regression of shapes on size reveals that the three Dascyllus species have a common ontogenetic trajectory which clearly differs from that of C. viridis. During growth, allometry concerns each unit (e.g. shortening of the neurocranium and the mandible) and is identical in each Dascyllus species. However, it appears that the largest studied specimens of D. trimaculatus (90 mm SL) have similar shapes and, differ only in size from the largest ones of both other species (50-60 mm SL). [less ▲]

The present study is the outcome of 5 former studies aiming at the adaptation of the V.H.I. to singers. We propose in this last version a V.H.I. valid for all types of singer, dysodic or not. The reliability, validity and internal coherence was evaluated on a population of 192 classical singers and 27 non singers. The comparison of the mean scores at the test and the retest shows that the results at the retest are significantly inferior for the functional scale (p=0.013) and for the global score (p=0.006). The test/re-test stability is good (ICC : Functional scale (F) : 0.869, Emotional scale (E) : 0.846, Physical scale (P) : 0.85, Global score (G) : 0.878/ Spearman’s rho F : 0.855, E : 0.834, P : 0.858, G : 0.886). The internal coherence of each sub scale is good (Cronbach’s alpha : >0.80). The correlation between the 3 subscales is quite high (FvsE : 0,613 /EvsP : 0,737/ FvsP : 0,693) which means that each scale measures a specific dimension but that they are still homogeneous. The test/re-test difference between the singers and the controls are not significant but the control group has a greater variability in their answers (Levene test : F : p<0 .001; P : p=0.009 ; G : p=0.02). Three variables increase the results : being a solist (F : p=0.046; E : p=0.002; P : p=0.056; G : p=0.006), being an amateur (F : p<0.001; E : p=0.019; P : p<0.001; G : p=0.001), having a vocal complaint (F, E, P et G : p<0.001). In conclusion, this version of the V.H.I is reliable, valid and adapted to the population of classical singers. [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.

Genetic diversity and relatedness between 2 geographically distant Holstein populations (in Luxembourg and Tunisia) were studied by pedigree analysis. These 2 populations have similar sizes and structures and are essentially importing populations. Edited pedigrees included 140,392 and 151,381 animals for Tunisia and Luxembourg, respectively. To partially account for pedigree completeness levels, a modified algorithm was used to compute inbreeding. The effective numbers of ancestors were derived from probabilities of gene origin for the 2 populations of cows born between 1990 and 2000. The 10 ancestors with the highest contributions to genetic diversity in the cow populations accounted for more than 32% of the genes. Eight of these 10 ancestors were the same in both populations. The rates of inbreeding were different in the 2 populations but were generally comparable to those found in the literature for the Holstein breed. Average inbreeding coefficients per year, estimated from the data, ranged from 0.91 and 0.50 in 1990 to 3.10 and 2.12 in 2000 for the Tunisian and Luxembourg populations, respectively. Genetic links have also strengthened with time. Average additive relationships between the 2 populations were as high as 2.2% in 2000. Results suggest that it would be possible to investigate genotype by environment interactions for milk traits using the Tunisian and Luxembourg dairy populations. [less ▲]
