lar-arterial coupling, defined by the quotient of end-systolic elastance and effective arterial elastance, was preserved throughout all stages of exercise. Maximal pressures increased significantly during exercise, while end-diastolic volumes were essentially unchanged. Overall, these findings demonstrate that the healthy RV is not merely a passive conduit, but actively participates in cardiopulmonary performance during exercise by accessing an enormous amount of contractile and lusitropic reserve, ensuring that VA coupling is preserved throughout all stages of exercise.

METHODS first molar extractions were performed in adult, skeletally mature mini pigs and mice. Alveolar bone repair was evaluated at early, intermediate and late timepoints using quantitative micro-computed tomographic (μCT) imaging, histology, molecular, and cellular assays. Vital dye labeling was employed to quantify mineral apposition rates (MAR) in both species. RESULTS Despite a 3000-fold difference in weight, the relative proportions of the mini pig and murine maxillae and are equivalent. GSK2256098 in vitro Quantitative μCT demonstrated that within the posterior alveolar bone, the volume of mineralized bone was lower in mini pig than in the mice; during healing, however, the bone volume fraction was equivalent. The histologic appearance of healing sites was also comparable, and alkaline phosphatase (ALP) and tartrate resistant acid phosphatase (TRAP) staining showed a similar temporal and spatial distribution of bone remodeling. Vital dye labeling indicated equivalent MAR between the species. The absolute duration of the healing period differed In mice, complete healing was accomplished in ∼21 days. In mini pigs, the same process took four times longer. CONCLUSIONS Extraction socket healing is histologically equivalent between mini pigs and mice, supporting the hypothesis that the underlying mechanisms of alveolar bone healing are conserved amongst species.

In this paper, I describe the time use patterns in the years 1983 and 2015 by social class, and gender in the British context. Using sequence analysis methods, I show how the diversity of time use patterns in British society is socially stratified. I find that 13 clusters capture the heterogeneity of time use patterns and that these clusters are associated with social class, gender, and day of the week. These clusters capture patterns of paid and unpaid work schedules, as well as leisure patterns. The results show that men have experienced a reduction of the standard Monday to Friday 8-hr working day, while women have experienced a general increase in this type of schedule. On the other hand, patterns of domestic working days have reduced for women and increased for men. Important differences exist in paid and unpaid work patterns between social classes. Working-class women have experienced an important increase in shift work on weekends. They are also much more likely to be doing unpaid work on weekdays compared to upper-class and middle-class women. Working-class men are more likely to experience non-working days and leisure days on both weekdays and weekends and are more likely to be doing shift work. They are also more often doing unpaid work on weekdays compared to men in upper-class households. Patterns of childcare indicate that all families have increased their childcare time. Men in upper-class households in particular have experienced an important growth in childcare time between 1983 and 2015. I conclude by discussing how time use can further our understanding of social stratification. © 2020 The Authors.

Since cures are currently unavailable, major efforts in improving brain health need to focus on prevention, with emphasis on modifiable risk factors such as promoting physical activity. Moderate-intensity continuous training (MICT) paradigms have been shown to confer vascular benefits translating into improved musculoskeletal, cardiopulmonary and cerebrovascular function. However, the time-commitment associated with MICT is a potential barrier to participation, and high-intensity interval training (HIIT) has since emerged as a more time-efficient mode of exercise that can promote similar if not indeed superior improvements in cardiorespiratory fitness for a given training volume and further promote vascular adaptation. However, randomised control trials (RCTs) investigating the impact of HIIT on the brain are surprisingly limited. The present review outlines how the HIIT paradigm has evolved from a historical perspective and describes the established physiological changes including its mechanistic bases. Given the dearth of RCTs, the vascular benefits of MICT are discussed with a focus on the translational neuroprotective benefits including their mechanistic bases that could be further potentiated through HIIT. Safety implications are highlighted and components of an optimal HIIT intervention are discussed including practical recommendations. Finally, statistical effect sizes have been calculated to allow prospective research to be appropriately powered and optimise the potential for detecting treatment effects. Future RCTs that focus on the potential clinical benefits of HIIT are encouraged given the prevalence of cognitive decline in an ever-ageing population. This article is protected by copyright.
