    Directional functional connectivity analyses revealed a bidirectional causal loop between left parietal and frontal areas for table-related solutions, with frontal areas explaining the resolution of arithmetic competition behaviorally. Hence, this study isolated at least 3 neurofunctional networks orchestrated between hemispheres during calculation.As a newly discovered protein posttranslational modification, histone lysine crotonylation (Kcr) involved in cellular regulation and human diseases. Various proteomics technologies have been developed to detect Kcr sites. However, experimental approaches for identifying Kcr sites are often time-consuming and labor-intensive, which is difficult to widely popularize in large-scale species. Selleckchem Guanosine 5′-monophosphate Computational approaches are cost-effective and can be used in a high-throughput manner to generate relatively precise identification. In this study, we develop a deep learning-based method termed as Deep-Kcr for Kcr sites prediction by combining sequence-based features, physicochemical property-based features and numerical space-derived information with information gain feature selection. We investigate the performances of convolutional neural network (CNN) and five commonly used classifiers (long short-term memory network, random forest, LogitBoost, naive Bayes and logistic regression) using 10-fold cross-validation and independent set test. Results show that CNN could always display the best performance with high computational efficiency on large dataset. We also compare the Deep-Kcr with other existing tools to demonstrate the excellent predictive power and robustness of our method. Based on the proposed model, a webserver called Deep-Kcr was established and is freely accessible at http//lin-group.cn/server/Deep-Kcr.

    Given increasing incidence of cognitive impairment and dementia, further understanding of modifiable factors contributing to increased healthspan is crucial. Extensive literature provides evidence that physical activity (PA) delays the onset of cognitive impairment; however, it is unclear whether engaging in PA in older adulthood is sufficient to influence progression through cognitive status categories.

    Applying a coordinated analysis approach, this project independently analyzed fourteen longitudinal studies (NTotal = 52,039; mean baseline age across studies= 69.9-81.73) from North America and Europe using multi-state survival models to estimate the impact of engaging in PA on cognitive status transitions (non-impaired, mildly impaired, severely impaired) and death. Multinomial regression models were fit to estimate life expectancy (LE) based on American PA recommendations. Meta-analyses provided the pooled effect sizes for the role of PA on each transition and estimated LEs.

    Controlling for baseline age, sex, education and chronic conditions, analyses revealed that more PA is significantly associated with decreased risk of transitioning from non-impaired to mildly impaired cognitive functioning and death, as well as substantially longer LE. Results also provided evidence for a protective effect of PA after onset of cognitive impairment (e.g., decreased risk of transitioning from mild to severe cognitive impairment; increased likelihood of transitioning backward from severe to mild cognitive impairment), though between-study heterogeneity suggests a less robust association.

    These results yield evidence for the importance of engaging in PA in older adulthood for cognitive health, and a rationale for motivating older adults to engage consistently in PA.

    Despite evidence of negative aspects of the work-caregiving interface (e.g., work-family conflict) among family caregivers of people with dementia (PWD), little is known about the positive aspects (e.g., enrichment). We examined antecedents and outcomes of family-to-work enrichment (FWE) and work-to-family enrichment (WFE) among working family caregivers of PWD. In terms of antecedents, we investigated whether factors that alleviated work-family conflict increased enrichment.

    We conducted a three-wave 6-month-interval longitudinal online survey of Japanese working family caregivers of PWD (N = 747). We examined the mediational effects of WFE and FWE on associations between participants’ work resources (job control, supervisor support, co-worker support, and organizational support) and caregiving support and their well-being (psychological distress and quality of life). We also examined the moderating effect of caregiving self-efficacy on the relationships between caregiving support/caregiving demands and ld focus on supporting companies to create family-friendly work environments. More research is needed on factors that increase FWE and moderate the relationship between enrichment and working family caregivers’ well-being.

    Healthy aging is associated with impairments in motor functioning. Such functioning is not limited to the physical execution of actions, but also involves cognitive processes that allow for goal-directed behavior. The present study examined whether aging affects 2 of such cognitive components that control motor functioning, namely action planning and action adaptation, and whether age effects are associated across components.

    A group of 103 participants aged 18-82 years performed 2 tasks that have previously been linked to action planning and adaptation, respectively.

    Despite observations that aging was associated with slower and less accurate responses, Bayesian models showed evidence indicating that older age was not associated with poorer action planning and conflict adaptation.

    These findings challenge the view that healthy aging is associated with a general deficit in motor functioning and suggest that some cognitive aspects of motor control may be relatively spared.
