Summary: This study examined the test-retest reliability of submaximal fitness test (SMFT) outcome measures derived from different protocols and analytical techniques. The results showed that exercise heart rate, vertical PlayerLoad, and contact time had the highest degrees of reliability, regardless of the SMFT protocol or analytical approach.

Summary: Parkinson's disease is characterized by exaggerated beta activity in the cortico-basal ganglia motor loops. This study investigates the relative contribution, dopamine dependency, and clinical correlations of oscillatory vs. non-oscillatory beta activity. The results suggest that the oscillatory component of beta activity is dopamine dependent and may play a role in the pathophysiology and progression of Parkinson's disease.

Summary: The present meta-analysis examined the effects of low-volume high-intensity interval training (LV-HIIT) on cardiometabolic health and body composition. The results showed that LV-HIIT can improve cardiorespiratory fitness, lower blood pressure, and reduce fat mass, with no significant differences compared to moderate-intensity continuous training and high-volume HIIT.

Summary: This study investigated the impact of cooking skills and cooking with processed foods on health and diet outcomes. The findings suggest that individuals with poor cooking skills are less likely to have adequate fruit and vegetable intake and are more likely to have obesity. It also indicates that in addition to improving cooking skills, reducing the use of processed foods is important for promoting better health and diet outcomes.

Summary: This study investigated the changes in the gut microbiome of in-home healthcare patients after consuming MR-Amazake. The results showed that MR-Amazake alleviated constipation symptoms and caused significant changes in the gut microbiome in some patients, primarily associated with Bifidobacterium. These changes were observed only during MR-Amazake intake, and the gut microbiome returned to its original state after discontinuation. Continuous consumption of MR-Amazake is necessary to sustain these changes.

Summary: This study describes the timing of physical activity for children on school and weekend days and explores the differences in timing across sex and body mass index categories. The results suggest that normal weight boys are more active than boys with obesity, while girls' physical activity levels are similar across different BMI categories. Additionally, there are timing differences in physical activity on school days and weekends.

Summary: This study investigated the characteristics of spatio-temporal attention using electroencephalography. The results showed that dynamic alpha power modulations and slow negative potentials were correlated with subsequent memory performance, indicating a preferential allocation of attention to task-relevant locations and time points. This study provides important insights into the key signatures of spatio-temporal top-down attention.

Summary: The development of scars after burns is a common and significant healthcare challenge that affects the lives of many patients. This review discusses the different forms of fibrosis that occur after burns, highlighting the impact of burn severity on scar development, and exploring the systemic response induced by burns and the role of fibroblasts in skin healing.

Summary: Fibrotic scarring is a common response to various lesions in the central nervous system, where perivascular cells give rise to stromal fibroblasts. This review summarizes the current understanding of fibrotic scar formation and provides an evaluation of perivascular cells using human single-cell gene expression datasets.

Summary: This study investigates the contributions of ERG channels and TTCCs to the pacemaker and atrioventricular conduction in zebrafish larvae and explores the mechanisms causing atrioventricular block. The zebrafish lines expressing Ca2+ biosensors in the heart provide a valuable model for studying physiological feedback mechanisms and complex arrhythmias.

Summary: This brief review summarizes recent observations on the impact of myocardial steatosis on cardiac morphology and function. Research suggests that myocardial steatosis leads to adverse cardiac remodelling and left ventricular dysfunction. The use of 1H magnetic resonance spectroscopy for clinical translation in this field is discussed.

Summary: The contribution of environmental factors is more strongly related to changes in body composition than genetic ones. Additionally, the presence of the risk allele combined with unfavorable environmental factors like ACEs leads to visible interaction effects, resulting in increased BMI z scores and FMI z scores in children.

Summary: This meta-analysis compared the peak changes in indirect markers of exercise-induced muscle damage (EIMD) in youths versus adults and found that the magnitude of EIMD is substantially less in youths, especially in the upper limbs for muscle soreness. These findings are important for guiding the potential impact of EIMD on youth athletes during training.

Summary: High altitude is a natural environment for studying human acclimatization and adaptation. However, there is a mismatch between high-altitude populations and the countries where high-altitude research has been conducted. The majority of research has focused on lowlanders visiting high altitude rather than high-altitude natives, and there is under-representation of females in high-altitude physiology research.

Summary: Kv10.1 is a voltage-dependent K channel associated with human cancers, and its structure-function properties are not well understood. In this study, we examined the interaction between the antiarrhythmic drug desethylamiodarone (desAd) and Kv10.1. We found that desAd binds to both closed and open channels, with most inhibition occurring from the open state. The affinity of desAd is approximately five times smaller than that of amiodarone. Additionally, desAd does not inhibit the Kv10.1 Cole-Moore shift, suggesting that a hydrophobic interaction between amiodarone and Kv10.1 is involved in the inhibition of the Cole-Moore shift, which is lost with desAd.
