One of the critical aspects of athletes’ fitness for effective competitive performance is the development of special cognitive qualities, in particular attention deficits. The development and enhancement of attention is important for increasing the effectiveness of sporting activities, and above all as a tool for controlling what happens when playing sports. However, original techniques of attention improvement in children are, to date, insufficient. The age of 8-10 is known to be a sensitive period for attention development. In our opinion, these are all strong arguments for developing a comprehensive methodology for developing young badminton players’ attention. During the pedagogical experiment, standard tests were used: the application of Gorbov’s tables, ‘Pyramid-tunnel’, the application of a Correction table; pedagogical observation and mathematical processing of the results using Microsoft Office Excel 2007. The credibility of disparities was calculated against Student’s criteria at significance level р . 0.05. The main constituents of attention for being successful in badminton are the scope, capability for shifting and keeping focus. The proposed integrated technique of attention improvement in young badminton players at the age of 8-10 caused a substantial improvement of sports achievements in the test group compared to the reference group. This shows that our methodology has a positive trend in the development of attention functions and is effective for young athletes.

Objective: To evaluate the effectiveness of placing a resorbable collagen barrier in impeding the extrusion of obturation material in primary molars undergoing resorption. Study design: All the 94 canals in 47 mandibular molars were allocated to 2 groups- Group ‘A’- 47 canals with collagen barrier (Test group) and Group ‘B’- 47 canals without collagen barrier (Control group) based on randomization protocol. Pulpectomy was performed and obturation of both test and control canals were radiographically assessed. Pearson’s chi – square test was applied to analyze the results. The significance level was predetermined at p < 0.05. Results: Among the test group, 93.6% of the canals showed no extrusion while, 6.4% showed visible extrusion of the material outside the apex. In the control group, 83% showed no extrusion whereas 17% of the canals showed visible extrusion outside the apex. But no significant difference was noted (p>0.05). Conclusion: The placement of resorbable collagen barrier in the apical third of the canal prevented the extrusion of obturating material beyond the apex in resorbing primary molars.

Abstract. Although the temporal changes of aerosol properties have been widely investigated, the majority focused on the averaged condition without much emphasis on the extremes. However, the latter can be more important in terms of human health and climate change. This study uses a previously validated, quality-controlled visibility dataset to investigate the long-term trends of extreme surface aerosol extinction coefficient (AEC) over China, and compare them with the median trends. Two methods are used to independently evaluate the trends, which arrive at consistent results. The sign of extreme and median trends are generally coherent, whereas their magnitudes show distinct spatial and temporal differences. In the 1980s, an overall positive trend is found throughout China with the extreme trend exceeding the mean trend, except for Northwest China and the North China Plain. In the 1990s, AEC over Northeast and Northwest China starts to decline while the rest of the country still exhibits an increase. The extreme trends continue to dominate in the south while it yields to the mean trend in the north. After year 2000, the extreme trend becomes weaker than the mean trend overall in terms of both the magnitude and significance level. The annual trend can be primarily attributed to winter and fall trends. The results suggest that the decadal changes of pollution in China may be governed by different mechanisms. Synoptic conditions that often result in extreme air quality changes might dominate in the 1980s, whereas emission increase might be the main factor for the 2000s.

The aim of this study was to compare the efficacy of dental plaque removal by brushing with and without conventional dentifrice. Twenty-four students aged 17 to 28 years participated in this randomized controlled clinical trial. Quadrants 1-3 or 2-4 were randomly allocated to the test group (brushing without dentifrice) or control group (brushing with dentifrice). After 72 h of cessation of oral hygiene, Quigley & Hein (Turesky) plaque index was assessed before and after brushing by a calibrated and blind examiner. Overtime and intergroup comparisons were performed by Student's paired sample t-test at 5% significance level. The results showed that both groups after toothbrushing presented statistically significant reductions in plaque, with no differences between them (from 3.06 ± 0.54 to 1.27 ± 0.26 versus from 3.07 ± 0.52 to 1.31 ± 0.23). A separate analysis of the buccal and lingual aspects also showed no significant differences between groups. It may be concluded that the use of a conventional dentifrice during toothbrushing does not seem to enhance plaque removal capacity.

The objective of the research is to develop, substantiate and evaluate the effectiveness of interval training methods during physical training of students of higher educational institutions pursuant to changes in physical performance.Methods.  The reference group (RG) consisted of 20 students (5 male and 15 female), the test group (TG) — 26 (5 male and 19 female). The RG students did fitness during their physical training classes at the university, while the TG students, besides the same program, did Tabata training in class and independently on their own at three levels of intensity four times a week for four weeks.We evaluated the effectiveness by the changes in students’ physical performance. We used χ2 tests (binary variables) to compare the output characteristics in the groups, t–tests (continuous variables) and Mann-Whitney test to compare the distribution of ordinal variables, and Wilcoxon test (related samples).Results. During the month of the forming experiment being conducted, the TG students’ physical performance showed the increase of + 38.9% and was reliably different from the results of the initial period (p < 0.05). The anthropometric indicators did not significantly change in their dynamics, nor was there any difference between the comparison groups.The evaluation of the effectiveness of interval training by the Tabata methods pursuant to the dynamics of the students’ physical performance allowed to objectively prove the positive effect that additional independent training of students has when implemented.

Purpose:To investigate the influence of flushing thoracic stent-grafts with carbon dioxide and perfluorocarbon on the amount of gas released during stent-graft deployment in thoracic endovascular aortic repair (TEVAR). Materials and Methods: Ten TX2 ProForm thoracic stent-grafts were deployed into a water-filled container with a curved plastic pipe and flushed sequentially with carbon dioxide, 20 mL of liquid perfluorocarbon (PFC), and 60 mL of saline. Released gas was measured using a calibrated setup. The volume of released gas was compared with the results of an earlier published reference group, in which identical stent-grafts were flushed with 60 mL saline alone as recommended in the instructions for use. Results: The average amount of gas released in the test group was 0.076 mL, significantly lower (p<0.001) than the mean 0.79 mL of gas released in the reference group. Big bubbles appearing at the tip of the sheath when deployment was started were seen in all grafts of the reference group but in only 2 of the test group stent-grafts. Small bubbles were less frequent in the test group. Conclusion: The amount of gas released from thoracic stent-grafts during deployment can be influenced by different flushing techniques. The use of PFC in addition to the carbon dioxide flushing technique reduces the volume of gas released during deployment of tubular thoracic stent-grafts to a few microliters. This significant effect is presumably based on the high solubility of carbon dioxide in perfluorocarbon and could be a potential future approach to lower the risk of cerebral injury and stroke from air embolism during TEVAR.

Precipitation Trends

Accurately predicting precipitation trends is vital in the economic development of a country. This research investigated precipitation variability across 15 stations in the Swat River basin, Pakistan, over a 51-year study period (1961–2011). Nonparametric Mann-Kendall (MK) and Spearman’s rho (SR) statistical tests were used to detect trends in monthly, seasonal, and annual precipitation, and the trend-free prewhitening approach was applied to eliminate serial correlation in the precipitation time series. The results highlighted a mix of positive (increasing) and negative (decreasing) trends in monthly, seasonal, and annual precipitation. One station in particular, the Saidu Sharif station, showed the maximum number of significant monthly precipitation events, followed by Abazai, Khairabad, and Malakand. On the seasonal time scale, precipitation trends changed from the summer to the autumn season. The Saidu Sharif station revealed the highest positive trend (7.48 mm/year) in annual precipitation. In the entire Swat River basin, statistically insignificant trends were found in the subbasins for the annual precipitation series; however, the Lower Swat subbasin showed the maximum quantitative increase in the precipitation at a rate of 2.18 mm/year. The performance of the MK and SR tests was consistent at the verified significance level.

9004 Background: The role of treatment with Bev beyond PD is unclear in the multiline treatment strategy of advanced NSCLC.AvaALL(NCT01351415), a multinational, open-label, randomized phase III trial, assessed continuous Bev and SOC beyond first PD (PD1) in pts with NSCLC following first-line treatment with platinum-based chemo plus Bev. Here we present efficacy and safety data from AvaALL. Methods: Pts with NSCLC who received 4–6 cycles of chemo + Bev and ≥2 cycles of maintenance Bev were randomized after PD1 to second-line SOC therapy (docetaxel, pemetrexed or erlotinib) ± Bev. After second PD (PD2) and third PD (PD3), pts received third-line or fourth-line SOC ± Bev treatment, respectively. Primary endpoint was overall survival (OS). Secondary endpoints were OS rates (6, 12, and 18-months [mos]), progression-free survival (PFS) from PD1 to PD2/from PD2 to PD3, overall response rate (ORR), disease control rate (DCR), and safety. Data cut-off: 24 Jun 2016. Results: Overall, 485 pts were randomized (n = 475 treated). Pt characteristics were well balanced between the two arms. Bev plus chemo resulted in a median OS of 11.9 mos versus 10.2 mos for SOC alone (HR 0.84, 90% CI 0.71–1.00; p = 0.1016; 387 OS events). The primary endpoint was not met (416 OS events were required, at 10% two-sided significance level). OS rates were 10% higher in the Bev arm vs SOC alone at 6-, 12- and 18-mos. Median PFS2 was 4.9 mos with Bev vs 3.8 mos with SOC (HR 0.85, 90% CI 0.72–1.00; p = 0.0907). PFS3 was significantly improved (3.5 mos for Bev, 2.4 mos for SOC; HR 0.65, 90% CI 0.51–0.84; p = 0.0047). ORR and DCR were slightly higher in the Bev arm versus the SOC arm (ORR 9.7% vs 6.7%; DCR 86.2% vs 79.3%, respectively). No new safety signals were identified. Grade ≥3 adverse events were reported in 78.2% of Bev pts and 61.6% of SOC pts. Conclusions: Although the primary endpoint was not met, efficacy data suggest a positive trend for continued Bev plus SOC after PD1 compared with SOC alone. No cumulative safety signals were identified. Clinical trial information: NCT01351415.

Objective: To evaluate the efficacy of a 10-week afterschool nutrition and culinary education program in changing the culinary and nutritional behaviour, attitudes and knowledge of its 9-11-year-old participants, as assessed by parents and children.  Methods: Retrospective matched-pairs analysis of secondary pre-post survey data collected by Boîte à Lunch (BàL). Children (n=165-197; grades 4 and 5) and parents (n=53-57) who signed-up for the BàL workshops. The program was comprised of ten-week (2 hours/week) bilingual (French and English) themed sessions led by trained educators with focus on culinary skill development, nutrition education and hands-on cooking. Secondary objectives include: team-work, kitchen hygiene, compost, understanding of food systems. Workshops were held in community centres and schools in Montreal, Canada. Changes were analyzed using the expanded exact McNemar-Bowker test with a Bonferroni-adjusted significance level of 0.001631. Results: Culinary skill and knowledge improved based on all 23 measures (all p<0.001631). Of the six measures assessed for change in attitude, three were significantly improved. Of the two items used to asses a change of behaviour, one was significantly improved. 2 stand-alone post-workshop questions suggest a positive trend for improvements in each. Conclusion: Knowledge and culinary skill of youth can be improved through nutrition education and hands-on cooking. Culinary and nutritional attitudes and behaviours may be improved; further research is needed.

Chemical environmental factors trophic for the endocrine system and its organs produce negative influence on it that becomes apparent through growing incidence and pathomorphism of endocrine diseases. Our test group was made up of 102 children with diagnosed autoimmune thyroiditis (AIT) who were chronically exposed to metals (lead, manganese, nickel, chromium, and zinc) being components in emissions from metallurgic enterprises in Perm region. Our reference group included 46 children with AIT who lived beyond zones influenced by the aforementioned enterprises in areas with the sanitary-hygienic situation being relatively favorable. We comparatively analyzed the results of clinical and ultrasound examinations that focused on evaluating children’s thyroidal and immune state. A growth in incidence with thyroiditis amounted to 63.6 % on the test territory over 10 years and it was 1.6 times higher than on average in the region (40.8 %); there was no growth in the indicator detected on the reference territory. Concentrations of chromium, nickel, lead, zinc, and manganese higher than regional background level were 1.7–5.5 times more frequently detected in blood of children from the test group against the reference one. A number of AIT cases was higher among exposed boys (by 2.0 times, p = 0.070); exposed children also had higher Ig A, M, and G contents in blood serum (by up to 2.9 times, p = 0.015–0.056), higher TSH levels (by 2.0 times, p = 0.096), and lower free T4 contents (by 5.4 times, p = 0.057). Diffuse damage to the thyroid gland was by 1.3 times more frequent under exposure to adverse factors created by metallurgic production; AIT combined with other diseases was also more frequent (p = 0.041). Rates and growth in incidence of thyroid gland diseases and thyroiditis are by 1.3–2.3 times higher among children and teenagers living on territories where metallurgic enterprises are located against the same indicators on territories where sanitary-hygienic situation is relatively favorable. We detected less apparent gender-related differences in AIT frequency, a greater number of improper thyroidal state, elevated risks of diffuse changes in the thyroid gland and activation of humoral immune response that was by 2.2–3.4 times more frequent together with concomitant damage to other systems under elevated contents of metals in blood.
