Background The adverse health effects of sugar-sweetened beverage consumption have been studied worldwide. There are several reports on actual sugar contents in sugar-sweetened beverages. However, there is no recent report on actual sugar contents in Japanese sugar-sweetened beverages. Therefore, we attempted to analyze glucose, fructose, and sucrose contents in Japanese common beverages. Methods Glucose, fructose, and sucrose contents in 49 beverages including 8 energy drinks, 11 sodas, 4 fruit juices, 7 probiotic drinks, 4 sports drinks, 5 coffee drinks, 6 green tea drinks, and 4 tea drinks were determined using the enzymatic methods. Results Tow zero calorie drinks, 2 sugarless coffee drinks, and 6 green tea drinks contained no sugar. Three coffee drinks contained only sucrose. The orders of median glucose, fructose, and sucrose contents in categorized beverages containing sugars were as follows: for glucose, fruit juice > energy drink ≥ soda >> probiotic drink > black tea drink > sports drink; for fructose, probiotic drink ≥ energy drink > fruit juice > soda >> sports drink > black tea drink; and for sucrose, black tea drink > energy drink ≥ probiotic drink > fruit juice > soda > coffee drink >> sports drink. The rate of total fructose content in total sugar content in 38 sugar-containing beverages was approximately 40-60%. The total sugar content analyzed was not always equivalent to carbohydrate content indicated on the nutrition label. Conclusions These results indicate that actual sugar content in Japanese common beverages is necessary for the exact assessment of beverage-derived sugar intake.

Abstract: Alginate has an imbibition property if it comes in contact with water that will affect the dimensional stability. Green tea (Camellia sinensis) contains phenolic compounds which can minimize the imbibition process while it is used in disinfection of alginate impression. This study was aimed to analyze the differences in the dimensional stability of alginate impressions after immersion in green tea leaf extract based on time variation. This was an experimental post-test laboratory study only. The one way Anova test on the anteroposterior and mediolateral dimensions showed that variation of immersion time in 50% green tea leaf extract could affect the dimensional stability. Moreover, the post hoc Games Howell test on the anteroposterior dimension and the post hoc LSD test on the mediolateral dimension resulted that there were significant differences between the control group and the groups of 5 minutes, 15 minutes, 30 minutes, and 50 minutes of immersion. Among all alginate impressions, the one immersed for 15 minutes was still in accordance with the standard of the American Dental Association. In conclusion, 15-minute immersion of alginate impression in 50% green tea leaf extract was the best time variation.Keywords: alginate, dimensional stability, green tea leaf extract 50% Abstrak: Alginat memiliki sifat imbibisi bila berkontak dengan air yang akan memengaruhi stabilitas dimensi alginat.

The aim of this in vitro study was to investigate the degree of C=C double bond conversion of high-viscosity dimethacrylate- or ormocer-based bulk-fill composites as a function of measurement depth. Four bulk-fill composites (Tetric EvoCeram Bulk Fill, x-tra fil, SonicFill, and Bulk Ormocer) and the conventional nanohybrid composite Tetric EvoCeram were applied in standardized Class II cavities (n = 6 per group) and photoactivated for 20 s at 1350 mW/cm2. The degree of conversion of the composites was assessed using Fourier-transform infrared spectroscopy at seven measurement depths (0.15, 1, 2, 3, 4, 5, 6 mm). Data were analyzed using repeated measures ANOVA and one-way ANOVA with Bonferroni post-hoc tests (α = 0.05). The investigated bulk-fill composites showed at least 80% of their maximum degree of conversion (80% DCmax) up to a measuring depth of at least 4 mm. Tetric EvoCeram Bulk Fill and Bulk Ormocer achieved more than 80% DCmax up to a measuring depth of 5 mm, x-tra fil up to 6 mm. The conventional nanohybrid composite Tetric EvoCeram achieved more than 80% DCmax up to 3 mm. In contrast to the conventional composite, the investigated ormocer- and dimethacrylate-based bulk-fill composites can be photo-polymerized in thick layers of up to at least 4 mm with regard to their degree of C=C double bond conversion.

A urbanização nas zonas costeiras torna necessário avaliar o impacto antrópico sobre os ecossistemas associados. O objetivo deste trabalho foi analisar temporalmente a dinâmica de populações de macroalgas com potencial bioindicador, estabelecendo-as como ferramenta para avaliação da saúde ambiental. Foi amostrado o ambiente recifal intertidal da Praia de Formosa, no Município de Cabedelo, Estado da Paraíba, Nordeste do Brasil, durante intervalos trimestrais de agosto/2013 a novembro/2014. A variação temporal da frequência de ocorrência (F') das populações macrofitobênticas foi avaliada pela análise de variância (One-Way Anova) com teste Post-Hoc de Tukey. A influência das variáveis ambientais sobre F’ foi avaliada pela Correlação Linear de Pearson e pela PERMANOVA. A análise da qualidade ambiental e a proposta de biomonitoramento basearam-se no Grupo 1, formado por espécies perenes e/ou raras com maiores valores ao longo do Componente Principal 1 (CP1) da Análise de Componentes Principais (ACP), e Grupo 2, formado por espécies com comportamento errático com menores valores ao longo do CP1 da ACP. Foram encontradas 33 espécies macrofitobênticas. A frequência de ocorrência apresentou variação temporal, porém não influenciada pelo conjunto de variáveis ambientais. Phyllodictyon anastomosans, Gelidiella acerosa e Gelidium corneum compuseram o Grupo 1, com Dictyopteris delicatula, Canistrocarpus cervicornis e Hypnea spinella formando o Grupo 2. O Grupo 2 apresentou correlação positiva com a temperatura, alcançando as máximas frequências nos períodos mais quentes, mas esse fator isolado não é capaz de explicar a distribuição errática das espécies. A ocorrência de espécies bioindicadoras de eutrofização foi considerada natural, fato que, aliado à alta frequência de espécies bioindicadoras de qualidade ambiental, sugerem que o Recife de Formosa não sofre impactos antrópicos significativos. O desaparecimento de espécies perenes ou crescimento populacional significativo de espécie rara (Grupo 1), bem como a fuga do padrão temporal de frequência ou dominância do recife pelas espécies do Grupo 2, são indícios da ocorrência de impactos. Este trabalho fornece à gestão do Recife de Formosa uma eficiente ferramenta para avaliação do impacto urbano sobre a comunidade macrofitobêntica.

Summary The variables impacting the efficiency of the offensive phase of the game in ice hockey may be determining factor for both the training process and game strategies. The research aimed to acquire and expand the knowledge about selected goal-scoring characteristics in the National Hockey League. A total of 511 even-strength goals were recorded in 129 randomly selected games in a regular-season 2020/2021 by indirect observation. Goals were differentiated by selected variable dimensions: location of the offensive team’s puck possession gain before scoring a goal, game situation preceding a goal, and the number of passes of the offensive team preceding a goal. Data were analyzed by performing a one–way ANOVA. Post hoc multiple comparisons were performed using the Tukey HSD test. The significance level of p ≤ 0.05 was used. Significant differences were found within all variable dimensions (p= 0.00001). In terms of the puck possession gain location, zone 1 (along the boards in the offensive zone) was the zone with the significantly highest mean score (p= 0.00305). Offensive zone play was significantly the game situation preceding most of the goals (p= 0.00000). The interval of the passes that preceded most of the recorded goals was the interval of 1 – 2 passes (p= 0.00000). Acquired results point out the dominance of particular variables and may help coaches to determine the content of the training process and game strategies. Based on the assumption of the realization of similar research in different environments in terms of the quality and age category, if the analogy would be found between the results of the present study and the results of potential studies, we can state the trends applicable to youth training.

Purpose: The inconsistencies and variations of creatine kinase level due to modifiable and non-modifiable factors were the basis of this study. The aim was to find out the relationships between creatinine and creatine kinase in the blood of somatotypes.    Methods: The 122 males, aged 10 to 20 years, were classified according to their somatotypes. Somatotypes were measured by the ISAK method. By standard laboratory methods, creatinine and creatine kinase estimate. The IBM SPSS version 24 is used for calculation. One way ANOVA followed by post hoc tests was performed to compare the variables among the three groups (p<0.05).   Results: Creatinine level in the blood insignificantly deferred among the three somatotypes. The significant differences (p<0.05) were found in creatine kinase level in the blood and creatinine/creatine kinase ratio among the three dominant Somatotypes. Creatine Kinase was significantly higher in Ectomorphs (212 U/L) than Endomorphs. Ectomorphs and mesomorphs have crossed normal creatine kinase levels (35 -175 U/L). The creatinine/creatine kinase ratio was found highest in endomorphs and lowest in the ectomorphs and significantly differed in three Somatotypes.   Conclusion: Creatinine production remains the same, indicating production of Creatinine is independent of specific body types. A significant higher Creatine Kinase level in Ectomorphs over Endomorphs showed fat content was not associated with it. Significant differences in Creatinine / Creatine Kinase ratio among Somatotypes suggested its relevance between cellular and morphological relationships and might uses as biomarkers.
