Long-term calorie restriction prevented memory impairment in middle-aged male mice and increased a marker of DNA oxidative stress in hippocampal dentate gyrus.

Calorie restriction (CR) is a non-invasive and economic approachknown to increase healthspan and life expectancy, through a decrease in oxidative stress, an increase in neurotrophins, among other benefits. However, it is not clear whether its benefit could be noted earlier, as at the beginning of middle-age. Hence, weaimed to determine whether six months of long-term CR, from early adulthood to the beginning of middle age (10 months of age) could positively affect cognitive, neurochemical, and behavioral parameters.

Effects of long-term social isolation on central, behavioural and metabolic parameters in middle-aged mice.

Social isolation gained discussion momentum due to the COVID-19 pandemic. Whereas many studies address the effects of long-term social isolation in post-weaning and adolescence and for periods ranging from 4 to 12 weeks, little is known about the repercussions of adult long-term social isolation in middle age. Thus, our aim was to investigate how long-term social isolation can influence metabolic, behavioural, and central nervous system-related areas in middle-aged mice.

Effects of acute exercise on spontaneous physical activity in mice at different ages.

Background: Exercise is often used to obtain a negative energy balance. However, its effects on body weight reduction are usually below expectations. One possible explanation is a reduction in spontaneous physical activity (SPA) after exercise since the increase in energy expenditure caused by the exercise session would be offset by the decrease in SPA and its associated energy cost.

Cross-cultural adaptation of body image assessment instruments for university students: a systematic review.

The theoretical-methodological process of cross-cultural adaptation of scales is fundamental for the expansion of research possibilities related to a given area and population, as instrument adequacy allows for the consistent assessment of the construct being studied. This article aims to highlight the different theoretical-methodological processes of cross-cultural adaptations of scales for assessing body image among young university students. The articles were selected in February 2020, with the following search descriptors: ("body image") and (young or "college students" or graduating or graduat *) and ("cross-cultural validation" or "cross-cultural adaptation"), in three databases-Scopus, PsycINFO, and Web of Science, without any time restrictions.
