Correlation analysis of epicardial adipose tissue and ventricular myocardial strain in Chinese amateur marathoners using cardiac magnetic resonance
<p><span>The volume of epicardial adipose tissue (EAT) is associated with an increased incidence of cardiovascular disease (CVD); however, only a few studies have examined its effect on the myocardial function of endurance in athletes. The association between the EAT and the variation of myocardial function is still unclear in amateur marathoners. Consequently, by using some sedentary individuals as the control, this study aims to evaluate the correlation between the EAT volume and the myocardial strain in the left and right ventricles of Chinese amateur marathoners by cardiac magnetic resonance (CMR).</span>The volume of epicardial adipose tissue (EAT) is associated with an increased incidence of cardiovascular disease (CVD); however, only a few studies have examined its effect on the myocardial function of endurance in athletes.

Biomechanical Analysis of Limits of Stability Using Computerized Posturography: Correlations with Functional Mobility in Elderly Individuals with Hip Osteoarthritis – A Cross-Sectional Study
<p>The study titled "Biomechanical Analysis of Limits of Stability Using Computerized Posturography: Correlations with Functional Mobility in Elderly Individuals with Hip Osteoarthritis – A Cross-Sectional Study" delves into the intricate relationship between postural stability and functional mobility in elderly patients suffering from hip osteoarthritis (OA). Utilizing advanced computerized posturography, the research quantitatively assesses the limits of stability (LOS) in various directional planes, providing a comprehensive biomechanical profile of the participants. The findings reveal significant discrepancies in LOS between hip OA patients and age-matched asymptomatic controls, underscoring the profound impact of hip OA on balance and stability. Additionally, the study examines the correlation between LOS measurements and functional mobility, as assessed by the Timed Up and Go (TUG) test. The results indicate a strong association, suggesting that diminished postural stability in hip OA patients contributes to impaired functional mobility. This cross-sectional analysis highlights the importance of targeted interventions to enhance stability and mobility in this population, aiming to mitigate the risk of falls and improve overall quality of life.</p>
Data from: Evolutionary patterns of ploidy and genome size variations show positive correlations with taxonomic diversity in tropical gingers (Zingiberaceae)
<p><strong>Premise: </strong>Cytogenetic traits such as an organism's chromosome number and genome size are taxonomically critical and can define angiosperm diversity. Variations in these cytogenetic traits by evolutionary processes such as polyploidization are known to be common, although underexplored in tropical plants. Zingiberaceae is a pantropical monocot family with ~1500 species where cytogenetic characters have often been used to define taxonomic boundaries, but a family-wide synthesis of cytogenetic patterns is absent.</p> <p><strong>Methods:</strong> A time-calibrated Bayesian phylogenetic tree was constructed to test for different models of chromosome number and genome size evolution in Zingiberaceae. We next tested how chromosome number and genome size variations differed with lineage-age, taxonomic diversity, and distributional range at two taxonomic ranks: within the family Zingiberaceae, and in the genus Hedychium using correlations, generalized linear models and phylogenetic least square models.</p> <p><strong>Key results:</strong> The most frequent changes in chromosome number within Zingiberaceae were demi-polyploidization and polyploidization (~57 % of the time), followed by ascending dysploidy (~27 %). The subfamily Zingiberoideae showed descending dysploidy at its base, while Alpinioideae showed polyploidization at its internal nodes. Although chromosome counts and genome sizes did not corroborate with each other, suggesting that they are not equivalent, at both taxonomic ranks, higher chromosome number variations and higher genome size variations were associated with higher taxonomic diversity and wider biogeographic distribution.</p> <p><strong>Conclusions:</strong> Within Zingiberaceae, multiple incidences of polyploidization were discovered, and these cytogenetic events appear to have impacted the morphology, decreased genome sizes, and increased taxonomic diversity, distributional range and invasiveness of plants within this family. </p>
