In this study, we have investigated the influence of the installation on the dynamometer and of the mode of contraction used during a rotator cuff muscle training. 24 subjects were divided into 3 groups. Two groups of 8 subjects performed a training of the Internal Rotators (IR) in concentric mode (60°/s and 240°/s) and of the External Rotators in eccentric mode (60°/s). The first group was trained at 45° of abduction; the second was trained at 90° of abduction. The third group did not perform any shoulder training. All patients were assessed thanks to the isokinetic device ((3) x 60°/s concentric – (5) x 240°/s concentric – (4) x 60°/s eccentric) before and after training. Only the group trained at 45° of abduction increased the isokinetic maximal peak torque (+ p) in concentric mode during the second isokinetic assessment. No subject showed improvement through the eccentric exercise. They also improved the throw of the ball (+ 8.5 %). Possible feeling of discomfort and signs of subacromial conflict explained that no progression was recorded after training at 90° of abduction. Likewise, the eccentric mode would major the inhibition limiting the strength increase. Even if 90° of abduction seems more specific for assessment, 45° of abduction is more suitable for training.

Besides the concentric classical ratios, the eccentric isokinetic assessment of the muscle shoulder allows us to build some specific ratios. The mixed ratio combines the eccentric maximal contraction of the external rotators (ER) and the concentric maximal strength of the internal rotators (IR). The mixed ratio is frequently decreased among overhead athletes. This imbalance could rise to shoulder tendinopathy, but seemed to be linked with field performance. The functional ratio corresponds to the balance between the ER in concentric mode and the IR in eccentric contraction. The unstable shoulder shows a trend to lower functional ratios, highlighting the weakness of the eccentric IR in that pathology. [less ▲]

The European Court of justice has long been aware of economists watching its judgements, particularly in the field of European Competition Law. This article considers first what exactly economists are looking at when they read the case law. Then, the typical content of their observation is analysed. Finally, the analysis turns to how the Court takes into account economist's view point on the case law. [less ▲]

Clinical affections of the locomotor and respiratory systems are the two main causes of poor performance in sport horses. Nevertheless, each subclinical affection of any system implicated in the oxygen system (respiratory, cardiovascular, blood, muscular and metabolic) may also become a limiting factor concerning the athletic capacities of the horse. A systematic medical examination of the horse, combining ail the clinical and laboratory exams, is thus necessary in order to establish a precise and comprehensive diagnosis regarding the different affections. The objectives of this communication are therefore to present the different methods currently available for the practitioner as well as the techniques recently developed for horses. The complementarity of the different clinical and laboratory exams, as well as the ideal moment for performing each test are clarified in order to accurately determine the different causes of poor performance as well as their functional repercussions [less ▲]

Examination of the horse during daily work is essential to follow-up his athletic préparation, however a good level of expérience is required to judge if he is ready to perform in compétition. Beyond thé subjective estimation of his behaviour and progress, objective parameters can be measured to evaluate his athletic capacity, level of fitness and health. Simple exercise tests can be integrated to thé horse's regular work schedule and parameters such as speed, heart rate and cardio-respiratory recovery may be readily monitored and compared during thé course of thé season. More sophisticated tests allow investigating exercise physiology of thé horse during exertion and thé way he tolerates and adapts to physical strain. It also allows early détection of subclinical diseases liable to impair performance. Like in human sports medicine, treadmill tests represent a safe investigation tool that is particularly well adapted to examining horses during exercise and helps diagnose one or several causes of poor performance, as many ancillary examinations may be implemented.

Forty-eight extracts from 16 common Belgian trees from the Walloon Region forest were evaluated for IN VITRO growth inhibitory activity against the human LoVo colon cancer, PC3 prostate cancer, and U373 glioblastoma cell lines. Our study was performed with the aim of selecting plant candidates in order to later isolate new anticancer compounds from an easily affordable tree material. Extracts from ALNUS GLUTINOSA (stem bark), CARPINUS BETULUS (leaves and stem bark), CASTANEA SATIVA (stem bark), FAGUS SYLVATICA (leaves), ILEX AQUIFOLIUM (leaves), LARIX DECIDUA (leaves), QUERCUS PETRAEA (stem bark), and QUERCUS ROBUR (leaves) showed for the first time potent IN VITRO growth inhibitory activity and could become easily affordable sources of potential new anticancer agents. Root extracts from ROBINIA PSEUDOACACIA, already known for containing cytotoxic lectins, also showed interesting activity. [less ▲]

The concentrations of pregnancy-associated glycoproteins (PAG) were determined in buffalo cows (Bubalus bubalis) using three different radioimmunoassay (RIA) systems (RIA-497, RIA-706, and RIA-708). Samples (10 mL) were collected by jugular venipuncture from Week 0 until Week 28 of pregnancy (9 females), and from parturition until Week 10 postpartum (13 females). During pregnancy, PAG molecules were detectable at Week 6 using the three aforementioned RIA systems (3.9 ± 1.3 ng/mL, 9.7 ± 1.3 ng/mL, and 9.9 ± 0.7 ng/mL for RIA-497, RIA-706, and RIA-708, respectively). These concentrations increased gradually until Week 28, reaching values of 39.6 ± 4.0 ng/mL (RIA-497), 50.5 ± 11.9 ng/mL (RIA-706), and 68.2 ± 20.8 ng/mL (RIA-708). PAG concentrations determined by RIA-497, RIA-706, and RIA-708 were strongly correlated throughout the entire gestation period, RIA-708 giving the higher concentrations. At parturition, the mean concentrations ranged from 34.9 ± 4.0 (RIA-497) to 84.7 ± 10.6 ng/mL (RIA-708). Thereafter, the concentrations decreased steadily, reaching very low levels (< 1.0 ng/mL) at Week 8 postpartum. In conclusion, PAG concentrations measured by the above three RIA systems showed a profile similar to those previously described in bovine species, with higher concentrations being detected by RIA-706 and RIA-708. However, the patterns of PAG concentrations, studied using the three aforementioned PAG-RIA systems, differed around parturition, with very low levels being observed in the female buffaloes [less ▲]

Located in the floodplain of the Mekong River and the Tonle Sap River, Batheay irrigation system and its reservoir directly receive floodwater from the Mekong. The Batheay reservoir formedby a ring dike functions as botha reservoir anda paddy field. In thewet season, the ring dike prevents floodwater fromentering the reservoir and rainy season rice is growninside the dike. After harvesting, the gateson the ring dike are openedto receive floodwater. The water is stored inside the dike for cultivating dry season rice outside the dike. In this paper, the irrigation system is studied as a model site for future development of the floodplain of the Tonle Sap Lake of Cambodia. Specifically, this paper is concerned with the study of water balance and analysis of the hydrologic components of the Batheay irrigation system, and the effectiveness of the ring dike system. The study found that floodwater of the Mekong River contributed about 74% to the total inflow to the Batheay reservoir. Contributions to the total water supply of reservoir water, floodwater remaining in the fields, and precipitation were 73, 12, and 15%, respectively. The efficiency of the systemwas found to be 92%. The dike system is expected to be a paradigm for the floodplain of the Tonle Sap Lake. [less ▲]

The purpose of this study was to compare pure concentric and eccentric isokinetic training with respect to their possible specificity in the progression of strength of the knee flexor and extensor muscles. Subjects were divided into 2 groups (eccentric or concentric training) and performed a specific training of dominant leg. Before and after the training session, isokinetic performances of trained leg and non-trained leg (cross-education) were evaluated. We observed a greater increase of muscle performances after eccentric training. A cross-education effect was measured exclusively after eccentric training session. We showed an increase of maximal eccentric performances after the pure concentric training. No significant progression of maximal concentric performance was measured after eccentric training.

Muscle strength and anaerobic power of the lower extremities are neuromuscular variables that influence performance in many sports activities, including soccer. Despite frequent contradictions in the literature, it may be assumed that muscle strength and balance play a key role in targeted acute muscle injuries. The purpose of the present study was to provide and compare pre-season muscular strength and power profiles in professional and junior elite soccer players throughout the developmental years of 15-21. One original aspect of our study was that isokinetic data were considered alongside the past history of injury in these players. Fifty-seven elite and junior elite male soccer players were assigned to three groups: PRO, n=19; U-21, n=20 and U-17, n=18. Players benefited from knee flexor and extensor isokinetic testing consisting of concentric and eccentric exercises. A context of lingering muscle disorder was defined using statistically selected cut-offs. Functional performance was evaluated throughout a squat jump and 10 m sprint. The PRO group ran faster and jumped higher than the U-17 group (P<0.05). No significant difference in isokinetic muscle strength performance was observed between the three groups when considering normalized body mass parameters. Individual isokinetic profiles enabled the identification of 32/57 (56%) subjects presenting lower limb muscular imbalance. Thirty-six out of 57 players were identified as having sustained a previous major lower limb injury. Of these 36 players, 23 still showed significant muscular imbalance (64%). New trends in rational training could focus more on the risk of imbalance and implement antagonist strengthening aimed at injury prevention. Such an intervention would benefit not only athletes recovering from injury, but also uninjured players. An interdisciplinary approach involving trainers, a physical coach, and medical staff would be of interest to consider in implementing a prevention programme. [less ▲]

The objective of the study was to measure the subjective long-term effects of vocal therapy (more than 6 months) in 29 patients suffering from dysfunctional dysphonia. Four subjective measurements were used: one visual analog scale ranging from 0 (not efficient at all) to 100 (very efficient); one question "Is the speech therapy still efficient?," answered by yes or no; the GRB parameters of the GRBAS scale (evaluated by the patient); and the VHI-10. The results show that 76% of the patients consider that the vocal therapy they received is still efficient. On the vocal quality (G), roughness (R), and breathiness (B) parameters, we observe a high degree of satisfaction on the G parameter (median=77). The scores on the R and B parameters are lower (median R=12, S=5). Roughness is significantly correlated to the Grade (Spearman coefficient r=0.516, P=0.004), whereas breathiness is not (P=0.251, NS). The comparison of the results on the VHI-10 pre and post treatment shows a significant decrease in the grade of perceived handicap (medians 15 vs 11, P=0.017). The correlations between the judgment of the treatment's efficacy and the vocal quality is significant (r=0.623, P<0.001) as well as the correlation between the VHI-10 and the length of the treatment (r=0.416, P=0.035). The conclusion can be made that speech therapy plays an important role in long-term treatment of dysfunctional dysphonias. [less ▲]

Artificial olfaction system (the so-called electronic nose) is a very promising tool to monitor the malodour in the field. Usual odour measurement techniques use human olfaction or analytical techniques. The first category represents the real odour perception but is not applicable to measure in continuous bad odours in the field. The second class of techniques gives the composition of the mixture but not the global information representative of the odour perception. The e-nose has the potentialities to combine “the odour perception” and the “monitoring in the field”. However to be able to reach this goal, the signal processing has to be adapted to work in complex environment. We have more than teen years experiments in the measure of environmental malodours in the field and the paper presents the minimal requirements that we consider essential for artificial olfaction system to become successful for this application.

BACKGROUND: Persistent use of glucocorticoid drugs is associated with bone loss and increased fracture risk. Concurrent oral bisphosphonates increase bone mineral density and reduce frequency of vertebral fractures, but are associated with poor compliance and adherence. We aimed to assess whether one intravenous infusion of zoledronic acid was non-inferior to daily oral risedronate for prevention and treatment of glucocorticoid-induced osteoporosis. METHODS: This 1-year randomised, double-blind, double-dummy, non-inferiority study of 54 centres in 12 European countries, Australia, Hong Kong, Israel, and the USA, tested the effectiveness of 5 mg intravenous infusion of zoledronic acid versus 5 mg oral risedronate for prevention and treatment of glucocorticoid-induced osteoporosis. 833 patients were randomised 1:1 to receive zoledronic acid (n=416) or risedronate (n=417). Patients were stratified by sex, and allocated to prevention or treatment subgroups dependent on duration of glucocorticoid use immediately preceding the study. The treatment subgroup consisted of those treated for more than 3 months (272 patients on zoledronic acid and 273 on risedronate), and the prevention subgroup of those treated for less than 3 months (144 patients on each drug). 62 patients did not complete the study because of adverse events, withdrawal of consent, loss to follow-up, death, misrandomisation, or protocol deviation. The primary endpoint was percentage change from baseline in lumbar spine bone mineral density. Drug efficacy was assessed on a modified intention-to-treat basis and safety was assessed on an intention-to-treat basis. This trial is registered with ClinicalTrials.gov, number NCT00100620. FINDINGS: Zoledronic acid was non-inferior and superior to risedronate for increase of lumbar spine bone mineral density in both the treatment (least-squares mean 4.06% [SE 0.28] vs 2.71% [SE 0.28], mean difference 1.36% [95% CI 0.67-2.05], p=0.0001) and prevention (2.60% [0.45] vs 0.64% [0.46], 1.96% [1.04-2.88], p<0.0001) subgroups at 12 months. Adverse events were more frequent in patients given zoledronic acid than in those on risedronate, largely as a result of transient symptoms during the first 3 days after infusion. Serious adverse events were worsening rheumatoid arthritis for the treatment subgroup and pyrexia for the prevention subgroup. INTERPRETATION: A single 5 mg intravenous infusion of zoledronic acid is non-inferior, possibly more effective, and more acceptable to patients than is 5 mg of oral risedronate daily for prevention and treatment of bone loss that is associated with glucocorticoid use.
