Background: Fatigue, lack of motivation and low compliance can be observed in nursing home residents during the practice of physical activity. Because exercises should not be too vigorous, whole body vibration could potentially be an effective alternative. The objective of this randomized controlled trial was to assess the impact of 3-month training by whole body vibration on the risk of falls among nursing home residents. Methods: Patients were randomized into two groups: the whole body vibration group which received 3 training sessions every week composed of 5 series of only 15 seconds of vibrations at 30 Hz frequency and a control group with normal daily life for the whole study period. The impact of this training on the risk of falls was assessed blindly by three tests: the Tinetti Test, the Timed Up and Go test and a quantitative evaluation of a 10-second walk performed with a tri-axial accelerometer. Results: 62 subjects (47 women and 15 men; mean age 83.2 ± 7.99 years) were recruited for the study. No significant change in the studied parameters was observed between the treated (n=31) and the control group (n=31) after 3 months of training by controlled whole-body-vibrations. Actually, the Tinetti test increased of + 0.93 ± 3.14 points in the treated group against + 0.88 ± 2.33 points in the control group (p = 0.89 when adjusted). The Timed Up and Go test showed a median evolution of - 1.14 (− 4.75-3.73) seconds in the treated group against + 0.41 (− 3.57- 2.41) seconds in the control group (p = 0.06). For the quantitative evaluation of the walk, no significant change was observed between the treated and the control group in single task as well as in dual task conditions. Conclusions: The whole body vibration training performed with the exposition settings such as those used in this research was feasible but seems to have no impact on the risk of falls among nursing home residents. Further investigations, in which, for example, the exposure parameters would be changed, seem necessary [less ▲]

Background: Chorioamnionitis is one of the important causes of preterm labor. Preterm labor with chorioamnionitis is associated with oxidative stress. We reported that 4-hydroxy-2-nonenal (4-HNE), a major end product of oxidative fatty acid metabolism, is accumulated in the placenta with chorioamnionitis. The aim of this study was to confirm the effect of 4-HNE on cyclooxygenase-2 (COX-2) and prostaglandin (PG) induction in the uterine myometrial tissues. We also examined the effect of N-acetylcysteine (NAC) on 4-HNE-induced COX-2 expression. Methods: Uterine myometrial tissues were obtained from 5 patients. One of them underwent elective cesarean section without labor, and 4 of them underwent hysterectomy because of placental previa or atonic bleeding. We stimulated the uterine myometrial tissues with 4-HNE. In addition, the tissues were pretreated with NAC before 4-HNE treatment. The expression of COX-2 mRNA was observed by real-time PCR. PGE2 and prostacyclin release into the supernatants of the tissue cultures was measured by ELISA. Results: 4-HNE induced the COX-2 mRNA expression and PGE2 production in the uterine myometrial tissue culture in a dose-dependent and time-dependent manner. NAC inhibited 4-HNE-induced COX-2 expression. Conclusion: 4-HNE may play an important role in preterm labor. NAC might be protective against preterm labor under oxidative stress. [less ▲]

8-Epi-PGF2alpha, a prostaglandin-like compound generated by oxidative stress, has been shown to be an in vitro bronchoconstrictor in airways from healthy laboratory animals and healthy humans, but it has never been studied in diseased airways. Here, the bronchoconstrictive capacity of 8-epi-PGF2alpha on isolated bronchial rings (BR) of healthy and heaves-affected horses was evaluated by comparing the maximal effect and the potency of 8-epi-PGF2alpha to those of (1) acetylcholine (ACh), (2) its stereoisomer PGF2alpha and (3) its synthetic receptor agonist, U46619. Furthermore, the potential capacity of 8-epi-PGF2alpha to enhance the cholinergic (ACh) responsiveness of bronchial smooth muscle was investigated. 8-Epi-PGF2alpha contracted BR with a rank order of efficacy of Ach > U44619 > PGF2alpha > 8-epi-PGF2alpha in both healthy and heaves-affected horses. The contractile maximal response elicited by 8-epi-PGF2alpha was significantly smaller than that elicited by the other drugs, but was significantly higher in BR from heaves-affected horses than in those sampled in healthy horses, whilst pD2 values were similar. A subthreshold concentration of 8-epi-PGF2alpha (10-7 M) did not induce in vitro cholinergic hyper-responsiveness in BR of either healthy or heaves-affected horses. In conclusion, it has been demonstrated that 8-epi-PGF2alpha is an in vitro bronchoconstrictor of minor importance in healthy horses, but whose efficacy is significantly increased in heaves-affected horses.

OBJECTIVE: To study the effects of the slightly estrogen-dominant monophasic low-dose oral contraceptive (OC) Diane-35 (Schering AG, Berlin, Germany) (35 micrograms ethinyl estradiol [EE2] + 2 mg cyproterone acetate, a 17 alpha-hydroxyprogesterone derivative [17-OHP]) on glucose and insulin metabolism. DESIGN: Seven healthy young women were investigated by using the euglycemic hyperinsulinemic glucose clamp technique (insulin delivery rate = 100 mU/kg per hour for 120 minutes). This test was performed, after an overnight fast, during the last 7 days of a spontaneous cycle and within the last 5 days of pill intake during the sixth and twelfth cycle of a continuous treatment with Diane-35 in each subject. RESULTS: The three indexes measuring the insulin-induced glucose disposal during the clamp (glucose infusion rate, glucose metabolic clearance rate, and glucose infusion rate divided by plasma insulin plateau levels) were not significantly affected by Diane-35. In contrast, the metabolic clearance rate of the exogenous insulin infused during the clamp tended to be slightly increased with Diane-35 (significant after 6 but not after 12 cycles). CONCLUSION: These results suggest that a 1-year treatment with the OC Diane-35, which contains EE2 + a 17-OHP rather than a 19-nortestosterone derivative as the progestogen compound, does not significantly alter peripheral (presumably muscular) insulin sensitivity but slightly increases insulin (presumably hepatic) clearance.

The industrial revolution in the 1800s and the subsequent industrialization had the consequence of an anthropogenic release of many organic and inorganic pollutants. Among these pollutants, cadmium is very problematic due to its high toxicity. It can induce significant damage to the vegetation and an accumulation in farmland introduces the pollutant into the food chain. This creates a possible major health risk for humans. Poplar plants, as a member of the Salicaceae family, seem to possess a certain tolerance to this toxic metal and accumulate significant amount in their aerial parts, making poplar a possible candidate for phytoremedation. The metabolic and physiological impact of cadmium have been studied as well in field trials as in controlled laboratory conditions, but mostly in clearly targeted studies focusing on a few key aspects. The recent advent of more global techniques such as transcriptomics and proteomics, make it possible to obtain new results. In the thesis presented here, a proteomic study of the short-term and long-term effects of cadmium on poplar leaf and roots metabolic processes in controlled laboratory conditions was carried out. With the help of this technique, complemented with biochemical and physiological approaches and with morphological observations, it was possible to obtain results on the stress-coping mechanisms underlying an acute first response, but also on the more general adaptation mechanism which make it possible for the poplar plants to tolerate significant amounts of cadmium. Results showed a negative impact on important cell processes like photosynthesis and ATP synthesis and the antioxidant system, explaining the impaired growth. Similar results could be obtained in roots, although the stress seemed much more acute, as evidenced by the stronger accumulation of typical stress proteins (i.e. heat shock proteins). In a final set of experiments a controlled combination of two stresses (cadmium and nonlethal chilling stress; 4°C) allowed separating specific cadmium responses from a more general stress response. Cadmium had a much more severe impact on plant survival when combined with an additional constraints. In this present work, the procedures, results and conclusions obtained are presented in detail.

The toxicity of Fyto11, a plant resistance elicitor commercial formulation used to increase the natural resistance of Cucurbitaceae (cucumber, zucchini and melon) and Solanaceae (tomato and sweet pepper) against powdery mildew under greenhouse conditions, has been assessed on several beneficial arthropods: the honeybee Apis mellifera, the predatory miteTyphlodromus pyri, the aphid parasitic wasp Aphidius rhopalosiphi and the aphid predator Episyrphus balteatus. Tested at 0.5% and 1.0% spray dilution on plants, Fyto11 did not lead to significant corrected mortalities for E. balteatus larvae and adult wasps of A. rhopalosiphi, with a maximum of 5.4% mortality. No effects on reproduction capacity of the parasitic wasps were observed. The exposure of T. pyri protonymphs to Fyto11 on glass plates lead to corrected mortalities of 1.1% and 32.6% at 0.5% and 1.0% and to a reduction of female fertility of 9.0% and 25.4%, compared to the control performance. When assessed on the honeybee by contact and oral exposure, Fyto11 did not lead to significant effects, with LD50 estimated as > 10 μg a.i./bee (oral) and 12.5 μg a.i./bee (contact), leading to HQ ratio < 50 and classifying the product at no or low risk for honeybees. These results showed that the product was harmless for all beneficials at the proposed commercial rate, except for T. pyri at 1.0% on glass plates, where the product was rated as slightly harmful. Even if all the beneficial species’ diversity has not been assessed with this product, negative effects on non-target organisms are not expected in field conditions and Fyto11 can be considered as compatible with IPM programs.

A daily physical educationprogramme (one 40 minute session) lasting for three years was implemented in 14 schools (kindergarten and primary levels). These schools were located in the whole territory of the French Community in Belgium. More than 3.500 children were involved in the experimental programme. Its implementation demanded a close cooperation between classroom teachers and physical education specialists. The evaluation of the effects of the daily physical education programme was copleted on the basis of a multidimensional data collection. This paper deals essentially with the children's attitudes in the comparison of experimental aned control schools and the longitudinal aspect of the study. A progressive deterioration of the pupils' attitude towards school was evidenced. However, children from the experimental classes maintained a significantly more favourable attitude towareds school and towards classroom and specialists teachers than pupils from control classes at each investigated level.

An experiment was conducted to study effects of dietary vitamin E supplementation on animal performance, slaughter characteristics and meat quality traits in Belgian Blue double-muscled bulls. Two groups of six bulls each (404 kg) were offered (close to ad libitum) a fattening diet based on sugar beet pulp for 154 days, at which time they were slaughtered. The diet given to the control group (CG) contained 12.5 mg vitamin E/kg concentrate. The vitamin E-treated group (VG) received the same concentrate plus a supplement of 1000 mg vitamin E per bull daily. Steaks from m. longissimus thoracis were used to determine meat quality characteristics, α tocopherol concentration and thiobarbituric acid reactive substances content (TBARS), an indicator of oxidation rancidity. Supplementation had no influence on performance or carcass characteristics. The main findings were that vitamin E doubled the muscle alpha tocopherol level (1.9 vs. 0.9 mg/kg; P<0.001), lipid oxidation was suppressed as indicated by TBARS values (P<0.01 at days 7, 9, 11 and 14 after slaughter), but muscle colour was not significantly affected although a* (redness) tended to be higher for VG.

Background and Objectives: Stereotypes about schizophrenia may lead to prejudicial attitudes and discrimination with debilitating effects on people diagnosed with schizophrenia. There is thus a need to develop interventions aiming to prevent, reduce or eliminate such stereotypes. The aim of this study was to evaluate the effects of a documentary film on schizophrenia on cognitive, affective and behavioural aspects of stigmatisation. Methods: Forty-nine participants were assessed on measures of stereotypes and social distance, and on the Model of Stereotype Content, which includes measures of stereotypes, emotional reactions and behavioural tendencies. Participants were randomly assigned into either a condition in which they viewed the documentary film (Film group), or into a control condition in which no intervention was conducted (Control group). Results: Only participants in the Film group revealed a significant decrease of negative stereotypes (Dangerousness and Unpredictability) and desired Social distance, and a significant increase in the perception of sociability in persons with schizophrenia. Limitations: Small sample size and its reduced generalizability are the main limitations in this study. Conclusions: These findings suggest that a documentary film promoting indirect contact with people diagnosed with schizophrenia is a promising tool to prevent and reduce stigmatisation regarding schizophrenia.

This study aims to measure under barn conditions the emissions of NH3, N2O, CH4 and CO2 associated with gestating sows (trial 1) and fattening pigs (trial 2) fed either a control diet (CTD) based on cereals or a high-fibre diet (HFD) based on sugar beet pulp (SBP). Three successive batches of 10 Belgian Landrace gestating sows were used for trial 1. Two successive batches of 24 Pi etrain Belgian Landrace fattening pigs were used for trial 2. Animals were kept on slatted floor. The gas emissions were measured by infrared photoacoustic detection and expressed per day and per livestock unit, equals to 500 kg body weight. Similar trends were observed for both animal types. With HFD, the NH3 emissions were reduced (27.2 vs. 36.5 g for the gestating sows, P < 0.001; 23.2 vs. 45.0 g for the fattening pigs, P < 0.001) but the CH4 emissions were increased (41.5 vs. 21.0 g for gestating sows, P < 0.001; 37.9 vs. 27.2 g for fattening pigs, P < 0.001). The fibre content of the diet had not significant impact on N2O emissions (around 1.4 g for gestating sows and 2.1 g for fattening pigs, P > 0.05), and on CO2 emissions (around 6.0 kg for gestating sows and 9.1 kg for fattening pigs, P > 0.05). Most of manure parameters did not statistically differ regarding the treatment. Reproductive performance and body condition of the sows were not affected by the diet. However, growth performance and carcass traits of the HFD-fed fattening pigs were deteriorated compared to CTD. [less ▲]

This study examines the potential effects of a new micro hydroelectric power plant (MHPP) on the behaviour (habitat use, movements) and population abundance of European grayling (T. thymallus) and brown trout (S. trutta) in the Lhomme (Belgian Ardennes). Thirteen grayling and five brown trout were captured before their spawning period and were manually radio-tracked up to 6 times a week. Population density and biomass were estimated into two different sampling sectors with electric fishing, before and after the MHPP started up. The mobility patterns of grayling and trout in the reach of the river Lhomme influenced by the MHPP strongly contrasted with results obtained in an undisturbed river of the same type in the Belgian Ardennes. Movements were mostly restricted and rarely increased during the spawning period. Spawning took place, but was disturbed by hydropeakings. The population biomass of grayling and trout decreased by 61 % and 23 % respectively, five months after the start-up of the MHPP exploitation. [less ▲]
