Current regulatory requirements for the development of disease-modifying drugs in osteoarthritis (OA) still consider the measurement of joint space narrowing (a change in joint space width over many years) on plain x-rays as the appropriate primary end point for the demonstration of efficacy. However, other outcomes have recently been proposed. Among these, time to joint replacement appears to be an attractive option. Preliminary results are encouraging; however, more data are needed before recommending joint replacement as a primary outcome in disease-modifying OA drugs. It should be acknowledged that, owing to potential biases (e.g., absence of recommended guidelines, socio–economic and gender disparities in the rates of knee surgery, variability from country to country and willingness of patients to undergo the surgery), a recent expert consensus panel did not recommend this particular outcome as the primary end point for assessing the success or failure of a disease-modifying drug. Other tools, such as magnetic resonance imaging or biochemical markers, have potential as outcome measures but more studies are needed. [less ▲]

The purpose of this study is to analyze the localization of palladium nanoparticles within their silica support, in two heterogeneous catalysts synthesized by the sol-gel process, with different metal loadings. Electron tomography demonstrates that the palladium particles are localized deep inside the silica skeleton. The use of digital image analysis further shows that the dispersion of palladium is optimal in the sample with the lowest loading. The particles are regularly spaced in the middle of the silica skeleton, with a distance between them comparable to the diameter of the struts of silica. [less ▲]

For patients who require treatment over a period of some years, intranasal administration of synthetic salmon calcitonin (SSCT) obviates the discomfort associated with administration by injection. Moreover, this mode of administration is not associated with the side effects normally encountered when calcitonin is injected intramuscularly or subcutaneously. The aim of this study was to assess, in normal subjects, the biological activity of nasal SSCT by comparing the fluctuations of parameters reflecting calcium-phosphorus metabolism after nasal instillation, injection of SSCT and injection of placebo, respectively. In nine healthy subjects, this instillation of 200 IU of SSCT into the nasal cavity caused a fall in serum calcium, a fall in serum phosphorus and a transient rise in parathyroid hormone levels similar to that observed after the intramuscular (i.m.) injection of 80 IU of SSCT. SSCT whether administered by the nasal route or by injection, does not inhibit endogenous calcitonin secretion. There were no changes in serum beta-endorphin, magnesium or erythrocyte magnesium levels after administration of calcitonin by the intranasal route or by injection. [less ▲]

The cell-mediated immunity (CMI) following bovine herpesvirus 4 (BHV4) infection has been poorly investigated in cattle. The in vivo response measured by a delayed type of hypersensitivity (DTH) assay has been reported to be positive in only few animals showing serological evidences of BHV4 infection. We have investigated the CMI following BHV4 infection by an in vitro antigen-specific interferon gamma (IFN-gamma) release assay, as an indicator of an actively acquired immunity to BHV4. Our preliminary results using a partially purified antigen suggest that there was a measurable CMI in 75 out of 168 animals (44.4%) originating from a farm with a clinical history and serological evidences (76.3% seropositivity) of BHV4 infection. If the results of serological tests and BHV4 IFN-gamma test are interpreted in parallel, 81.5% of the animals are classified positive, demonstrating the complementarity of these tests. The specificity of the BHV4 IFN-gamma test was supported by the absence of a measurable CMI in 41 animals originating from a farm with no clinical history or serological evidence of BHV4 infection. In an allied study, we developed a bovine herpesvirus 1 (BHV1) IFN-gamma test. This allowed us to measure the antigen specific IFN-gamma release after stimulation with a mixture of BHV1 and BHV4 antigens. Animals that were classified negative by the BHV4 IFN-gamma test and by the BHV1 IFN-gamma test, were classified negative after stimulation with a mixture of both antigens. Animals that were classified positive by the BHV4 IFN-gamma test or the BHV1 IFN-gamma test, were classified positive after stimulation with a mixture of both antigens. Taken together these results suggest that the in vitro assessment of the CMI after BHV4 infection should be further investigated as a specific and valuable alternative to the DTH assay. [less ▲]

This overview paper describes a study conducted for the Belgian Federal Public Service of Health, Food Chain Safety and Environment during 2006–2007. Home-produced eggs from Belgian private owners of hens were included in a large study aiming to determine concentration levels of various environmental contaminants. Bymeans of the analyses of soil samples and of kitchen waste samples, obtained from the same locations, an investigation towards the possible sources of contaminants was possible. Eggs, soils, faeces and kitchen waste samples were checked for the presence of dioxins, PCBs (including dioxin-like PCBs), organochlorine pesticides, trace elements, PAHs, brominated flame retardants and mycotoxins. The study design, sampling methodology and primary conclusions of the study are given. It was found that in some cases dioxin-like compounds were present at levels that are of concern for the health of the egg consumers. Therefore, measures to limit their contamination in eggs, produced by hens of private owners, were proposed and deserve further attentio [less ▲]

This paper describes the PREI (Posidonia oceanica Rapid Easy Index), a method used to assess the ecological status of seawater along Mediterranean French coasts. The PREI was drawn up according to the requirements of the Water Framework Directive (WFD 2000/60/EC) and was tested on 24 and 18 stations in PACA (Provence-Alpes-Côtes d’Azur) and Corsica respectively. The PREI is based on five metrics: shoot density, shoot leaf surface area, E/L ratio (Epiphytic biomass/leaf biomass), depth of lower limit, and type of this lower limit. The 42 studied stations were classified in the first four levels of status: high, good, moderate and poor. The PREI values ranged between 0.280 and 0.847; this classification is in accordance with our field knowledge and with our knowledge of the literature. The PREI was validated regarding human pressure levels (r²= 0.74). (http://eurex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2000:327:0001:0072:EN:PDF) [less ▲]

Posidonia oceanica (L.) Delile is a protected species, included in the Red list of marine threatened species of the Mediterranean. Because of its sensitivity to disturbance, P. oceanica is used as a bioindicator to define the health status of coastal waters. Monitoring methods generally require to sample plants, followed by measurements on picked shoots. This implies the total destruction of several tens of shoots. This study presents a method, “The Non Destructive Shoot Methodology”: NDSM, that permits the measurement of (1) the most used seagrass metrics, (2) the determination of C, N, P contents and (3) the measurement of the trace metal levels in P. oceanica leaves. Our technic has been firstly tested by comparison with the results obtained with classic method of biometry. Secondly, differences between levels of C, N, P and trace metals obtained with classic picking and our methodology were tested. Thirdly, the physiological consequences on the shoots were investigated (% of survival, growth, essential element contents (C, N, P, Fe, Cu...). The NDSM gives similar results to classic investigations to assess the ecological status of P. oceanica meadow (i.e. PREI, BiPO...) and avoid the uprooting of the “K-strategist” protected species. This methodology is usable in cases of monitoring and impact studies. [less ▲]

Current transportation models often do not explicitly address the degree of uncertainty in travel forecasts. Of particular interest in activity-based travel demand models is the model uncertainty that is caused by the statistical distributions of random components, i.e. micro-simulation error. Therefore, the main objective of this paper is to assess the impact of micro-simulation error on two key travel indices, namely the average daily number of trips per person and the average daily distance traveled per person. The effect of micro-simulation error will be investigated by running the activity-based modeling framework FEATHERS 200 times using the same 10% fraction of the population. Results show that micro-simulation errors are limited especially when disaggregation is limited to two levels. Notwithstanding, results indicate that for more elaborate analyses a 10% fraction might not be sufficient. The size of micro-simulation error increases along with complexity. Moreover, more commonly used transport modes such as using the car as driver have a lower error rate. Further research should investigate the impact of the population fraction on the micro-simulation error rates. Besides, one could also investigate other aspects (e.g. the number of activities) involved in the activity-scheduling process. [less ▲]
