    AbstractDuring the period of acquisition and first practice of movement skills, learning becomes more effective when various sensory channels are used. According to the Dual Coding Theory, students as learners code both visually and verbally incoming information into knowledge that can be stored and retrieved for subsequent use. The aim of the present study is the proposal of a new method for the teaching of fundamental motor skills that will be depended on a visual coding of movement information. Particularly, the morphological method for the analysis of dance is the proposed method according to which graphic visual symbols will be used to represent movement skills. It is expected that the use of the proposed teaching method will make teaching more effective, improving in this way the students’ motor skills

    Rapid determination of octanol–water partition coefficient using vortex-assisted liquid–liquid microextraction

    Vortex-assisted liquid–liquid microextraction (VALLME) coupled with high-performance liquid chromatography (HPLC) is proposed here for the rapid determination of octanol–water partitioning coefficients (Kow). VALLME uses vortex agitation, a mild emulsification procedure, to disperse microvolumes of octanol in the aqueous phase thus increasing the interfacial contact area and ensuring faster partitioning rates. With VALLME, 2 min were enough to achieve equilibrium conditions between the octanolic and aqueous phases. Upon equilibration, separation was achieved using centrifugation and the octanolic microdrop was collected and analyzed in a HPLC system. Six model compounds with log Kow values ranging between ∌0.5 and 3.5 were used during the present investigations. The proposed method produced log Kow values that were consistent with previously published values and the recorded uncertainty was well within the acceptable log unit range. Overall, the key features of the proposed Kow determination procedure comprised speed, reliability, simplicity, low cost and minimal solvent consumption.EP is grateful to the Region of Crete (Perifereia Kritis) for funding.

    OBJECTIVE: The aim of the present study was to evaluate lifestyle and health determinants of cardiovascular disease (CVD) risk among Greek elderly residents living in Eastern Aegean islands, in both Greece and Turkey. METHODS: Under the context of the MEDIS study, 724 older adults (aged 65 to 100 years) from 8 Eastern Aegean Sea Greek islands (n=100 living in Samothrace, 142 in Lesvos, 150 in Limnos, 76 in Ikaria, 52 in Kassos, 149 in Rhodes and Karpathos) and from Turkey (n=55older adults of Greek origin living on Gökçeada Island) were voluntarily recruited. Overall cardiometabolic risk was measured as the sum (range 0-4) of four common CVD risk factors (hypertension, diabetes, dyslipidemia and obesity). RESULTS: Greek islanders had higher CVD scores compared to Greeks of Gökçeada (1.9±1.1 vs 1.4±1.0 risk factors / participant, p<0.001). Further analysis revealed that the diet of Greek islanders was similar to the traditional Mediterranean diet; however, these individuals demonstrated 2-times higher odds (95% CI, 1.04-3.87) for having hypertension, 1.53-times higher odds (95% CI, 0.66-3.54) for having diabetes, 3.29-times higher odds (95% CI, 1.58-6.81) for having hypercholesterolemia; whereas they had 0.78-times lower odds (95% CI, 0.40-1.52) for being obese, compared to elderly Greek adults living on Gökçeada. CONCLUSIONS: Overall, CVD risk seems to be low among Eastern Aegean Islanders; certain differences in CVD risk factors exist between Greek islanders and their counterparts living in Gökçeada, and those differences may be attributed to various environmental, cultural and lifestyle factors

    Skeletal muscle mass and body fat in relation to successful ageing of older adults: The multi-national MEDIS study

    BACKGROUND: The determinants that promote successful ageing still remain unknown. The aim of the present work was to evaluate the role of skeletal muscle mass and body fat percentage (BF%), in the level of successful ageing. METHODS: during 2005-2011, 2663 older (aged 65-100 years) from 21 Mediterranean islands and the rural Mani region (Peloponnesus) of Greece were voluntarily enrolled in the study. Appendicular skeletal muscle mass (ASM), skeletal muscle mass index (SMI) and BF% were calculated using population formulas. Dietary habits, energy intake, expenditure and energy balance were derived throughout standard procedures. A successful ageing index ranging from 0 to 10 was used. RESULTS: The mean ASM mass was 24±6.0kg, the SMI was 0.84±0.21 and the BF% was 44%. Females had lower SMI and higher BF% in comparison with males, respectively [(SMI: 0.66±0.09 vs. 1.03±0.11; BF%: 51% vs. 34%, (p<0.001)]. High successful agers had better rates in ASM (p=0.01), SMI (p<0.001) and BF% (p<0.001), compared with the medium and low successful ones. Changes in SMI [b-coefficient (95% CI):2.14 (1.57 to 2.71)] were positively associated with successful ageing, while changes in BF% [b-coefficient (95% CI): -0.04 (-0.05 to -0.03)] were inversely associated with successful ageing. Results from sensitivity analysis showed that the effects of variations on body composition were consistent, less pronounced in the positive energy balance group and more pronounced among the oldest old. CONCLUSIONS: Body composition changes seem to be associated with lower quality of life in the older adults, as measured through successful ageing

    Is parental longevity associated with the cardiovascular risk and the successful aging of their offspring? Results from the multinational MEDIS study

    The aim of the present study was to evaluate the role of parental longevity and parental cardiovascular disease (CVD) history in CVD risk and successful aging of a random sample of older adults living in the Mediterranean basin and who participated in the MEDiterranean Islands (MEDIS) study. During 2005 to 2011, 2663 elders were voluntarily enrolled. A multidimensional successful aging index consisting of 10 components was used. Paternal and maternal longevity was defined as those older participants of whom both parents lived above the age of 90. The burden of CVD-related factors (CVD-RFs) was calculated as the total score of 4 major CVD-RFs (range 0-4). After adjustment, parental longevity was inversely associated with the burden of CVD-RFs ( P = .04). Moreover, parental longevity was positively associated with the older adults' successful aging score (ÎČ-coefficient [95% confidence interval]: .38 [0.06-0.71]). Parent's long living was revealed as an important factor for successful aging and for reduced CVD risk, suggesting that further research is needed in the genetic predisposition of longevity
