Organic dust contains pathogen-associated molecular patterns (PAMPs) which can induce significant airway diseases following chronic exposure. Mononuclear phagocytes are key protecting cells of the respiratory tract. Several studies have investigated the effects of PAMPs and mainly endotoxins, on cytokine production. However the sub-lethal cytotoxicity of organic dust components on macrophages has not been tested yet. The novel technology of high content analysis (HCA) is already used to assess subclinical drug-induced toxicity. It combines the capabilities of flow cytometry, intracellular fluorescence probes, and image analysis and enables rapid multiple analyses in large numbers of samples. In the present study, HCA was used to investigate the cytotoxicity of the 3 major PAMPs contained in organic dust, ie. endotoxin (LPS), peptidoglycan (PGN) and β-glucans (zymosan) on THP-1 monocyte-derived macrophages. LPS was used at concentrations of 0.005, 0.01, 0.02, 0.05, 0.1 and 1 μg/ml; PGN and zymosan were used at concentrations of 1, 5, 10, 50, 100 and 500 μg/ml. Cells were exposed to PAMPs for 24 h. In addition, the oxidative burst and the phagocytic capabilities of the cells were tested. An overlap between PGN intrinsic fluorescence and red/far-red fluorescent dyes occurred, rendering the evaluation of some parameters impossible for PGN. LPS induced sub-lethal cytotoxicity at the lowest dose (from 50 ng/ml). However, the greatest cytotoxic changes occurred with zymosan. In addition, zymosan, but not LPS, induced phagosome maturation and oxidative burst. Given the fact that β-glucans can be up to 100-fold more concentrated in organic dust than LPS, these results suggest that β-glucans could play a major role in macrophage impairment following heavy dust exposure and will merit further investigation in the near future.

The economic and statistical merits of a multiple variable sampling intervals (MVSI) scheme are studied. The problem is formulated as a double-objective optimization problem with the adjusted average time to signal as the statistical objective and the expected cost per hour as the economic objective. Bai and Lee’s ‎[2] economic model is considered. Then we find the Pareto-optimal designs in which the two objectives are minimized simultaneously by using the non-dominated sorting genetic algorithm. Through an illustrative example, the advantages of the proposed approach is shown by providing a list of viable optimal solutions and graphical representations, which indicate the advantage of flexibility and adaptability of our approach.

ultrasonography is currently more and more used in equine acute abdominal disease as well as in the follow-up of surgical colic patients because of its sensibility for the detection of small intestinal distension. General anaesthesia is known to diminish gastrointestinal motility even if there are no clinical signs associated with it. The aim of this study was to evaluate the effect of general anaesthesia on transabdominal ultrasonographic images of the small intestine in horses undergoing routine non abdominal surgeries. The ultrasonographic exams were performed in 19 horses before and after the general anaesthesia (immediately after the recovery and then 2h, 12h and 24h after it). Each ultrasonographic exam focused on the duodenum, the jejunum and the presence of peritoneal fluid. For the jejunum, 5 locations were used: on the ventral midline just caudally to the sternum, on the left and right cranial ventral parts of the abdomen, on the left and right inguinal regions. Other parameters such as the gut sounds and the postoperative fecal output were also recorded. Anova and Chi-square tests were used for the statistical analysis. No horse showed colic signs. No significant difference was found between the pre and post anaesthetic period considering the maximal diameter of the duodenum, the maximal diameter of the jejunum on the 5 locations and the peritoneal fluid. The contractions of the duodenum were increased at the recovery compared to before the anaesthesia (p= 0,0299). The small intestine was most visible at the recovery (57,5%) and then at 2 hours after it (38,3%). It seemed that the ventral midline just caudally to the sternum and the right and left inguinal regions were the best locations to observe the jejunum (with a mean of respectively 44,6%, 39,8% and 38,5% of visualization of the jejunum).The gut sounds were very significantly decreased at the recovery (p < 0,0001) and at 2h after it (p = 0,0006). The postoperative fecal output was not decreased. In conclusion, even if general anaesthesia seems to reduce temporarily the intestinal activity (decreased gut sounds in the early post anaesthetic period), it does not cause significant distension of the small intestine (almost the small intestinal diameters were in the normal range). If an increased diameter of small intestine is observed by ultrasonography after surgery it should therefore be attributed to a pathological process and not to the anaesthesia. [less ▲]

According to results of laboratory experiments and modelling, it can be observed that, if there is an influence of 2° and 4° angle of inclination on pull-off bond strength, it is however not statistically significant: the decrease of pull-off strength is usually no larger than 14% for 4°.

The efficiency of the composite repair system is usually evaluated through semi-destructive test: pull-off test. But some difficulties can also be induced by the eccentricity of the load application, due to incorrect placement of the test device. The paper presents the results of a research project and the impact of incorrect design on tensile strength values. According to results of laboratory experiments and modelling, it can be observed that, if there is an influence of 2o and 4o angle of inclination on pull-off bond strength, it is however not statistically significant: the decrease of pull-off strength is usually no larger than 8% for 2o [less ▲]

The European Union Common Agricultural Policy (CAP) holds as principal objectives, as they were outlined in the Treaty of Rome, the following: increase productivity, by promoting technical innovation and ensuring optimum use of factors of production, ensure a fair standard of living for the agricultural community, stabilize agricultural markets, secure availability of agricultural supplies and provide consumers with food at reasonable prices. Over time, and depending on certain factors, new secondary objectives have been added such as: environmental protection, biodiversity, animal welfare, enhancement of rural areas. In the North-East Region of Romania, the impact of rural development policies implemented through the National Rural Development Programme (NRDP) has been assessed at regional and local level utilizing a combined analysis of statistical databases.

Objectives: To assess the efficacy and safety of etoricoxib 60 mg once daily and naproxen 500 mg twice daily over a 138- week treatment period in patients with osteoarthritis ( OA). Methods: Two 1- year randomised, double blind, parallel group two- part base studies ( part I 12 weeks; part II 40 weeks), followed by an 86- week extension, in patients with OA ( hip or knee) were conducted at 80 clinical centres ( 19 countries). The studies had identical designs. Patients taking placebo in part I received etoricoxib or naproxen ( 1: 1 ratio) in part II and the extension; patients taking etoricoxib or naproxen in part I continued to receive the same treatment throughout the entire length of the studies. Co- primary efficacy end points were patient global assessment of disease status, and WOMAC questionnaire pain subscale and physical function subscale ( 100 mm VAS). Efficacy over 138 weeks was assessed by graphical analysis. Safety was assessed by observation of adverse experiences and laboratory and physical evaluations. Results: 997 patients entered ( 615 completed) the base studies. Of these patients, 463 patients entered the extensions. A total of 161 and 152 patients in the etoricoxib and naproxen groups, respectively, completed 138 treatment weeks. Etoricoxib and naproxen showed similar efficacy throughout the 138 weeks of treatment. For etoricoxib and naproxen, respectively, WOMAC pain assessments were 67 and 67 mm ( baseline); 28 and 29 mm ( 1 year), and 34 and 33 mm ( 138 weeks). Results for the other efficacy end points were similar to those seen with the WOMAC pain assessments. Both etoricoxib and naproxen were generally well tolerated. Conclusion: Both etoricoxib and naproxen demonstrated long- term clinical efficacy for the treatment of OA. Etoricoxib and naproxen were generally well tolerated. [less ▲]
