This chapter describes longitudinal findings from a socially diverse sample of 125 British children seen at ages two and four. Four models of social influence on executive function are tested, using multiple measures of family life as well as comprehensive assessments of children's executive functions. Our results confirm the importance of maternal scaffolding for young children's executive functions, but they also suggest positive effects of observational learning and adverse effects of disorganized and unpredictable family life; however, no support was found for an association between executive function and general positive characteristics of family interactions.

Chronic kidney disease (CKD) is defined by persistent abnormalities of kidney function or structure that have consequences for the health. A progressive decline of excretory kidney function has effects on body homeostasis. CKD is tightly associated with accelerated cardiovascular disease and severe infections, and with premature death.

Cognitive flexibility is the ability to appropriately adapt one's thinking and behavior to changing environmental demands and is conceptualized as an aspect of executive function. The dopamine system has been implicated in cognitive flexibility; however, a direct, that is, neurochemical, link to cognitive flexibility has not been shown yet. The aim of this study was, therefore, to investigate how cognitive flexibility is mediated by dopaminergic signaling in the ventromedial prefrontal cortex (vmPFC).

Objectives: This study aimed to investigate the association between relative hypothermia measured by a wearable device and cognitive function, and to clarify whether relative hypothermia is a useful indicator for preventing poor cognitive function.
Design: Cross-sectional study.
Setting And Participants: The study included 103 community-dwelling older adults aged 60 to 90 years.
In 2021, a year before ChatGPT took the world by storm amid the excitement about generative artificial intelligence (AI), AlphaFold 2 cracked the 50-year-old protein-folding problem, predicting three-dimensional (3D) structures for more than 200 million proteins from their amino acid sequences. This accomplishment was a precursor to an unprecedented burgeoning of large language models (LLMs) in the life sciences. That was just the beginning.

This meta-review provides the first meta-analytic evidence from published meta-analyses examining the effectiveness of acute exercise interventions on cognitive function. A multilevel meta-analysis with a random-effects model and tests of moderators were performed in R. Thirty systematic reviews with meta-analyses (383 unique studies with 18,347 participants) were identified.
