National trends and ecological factors of physical activity engagement among U.S youth before and during the COVID-19 pandemic: A cohort study from 2019 to 2021.

Background: This study aims to investigate the trends and ecological determinants of physical activity among U.S. children and adolescents during the 2019-2021 period, encompassing the COVID-19 pandemic's onset and subsequent years.

SMURF1 activates the cGAS/STING/IFN-1 signal axis by mediating YY1 ubiquitination to accelerate the progression of lupus nephritis.

Aggravated endoplasmic reticulum stress (ERS) and apoptosis in podocytes play an important role in lupus nephritis (LN) progression, but its mechanism is still unclear. Herein, the role of SMURF1 in regulating podocytes apoptosis and ERS during LN progression were investigated. MRL/lpr mice was used as LN model .

Digital Technology Use and Adolescent Mental Health Before and During the COVID-19 Pandemic: The Roles of Internet Addiction and Digital Competence.

This study examined whether Internet addiction (IA) and digital competence (DC) mediated the association between digital technology use and mental health problems in adolescents before and during the COVID-19 pandemic, when digital device use increased dramatically. Repeated cross-sectional data from a 3-year cross-cohort study adopting stratified random sampling were analyzed. In 2019, 569 adolescents (female = 312) from 14 secondary schools completed a DC assessment and an online survey on their digital technology use, IA, and mental health.

Child aggression and parenting behavior: Understanding the child-driven effects with parents' emotion regulation as a moderator.

The present study examined the longitudinal relations between child aggression and coercive parenting behaviors and the moderating role of parental emotion regulation strategies in these relations. The sample of this study were 168 children (88 girls; = 60.97 months, = 5.

Association between nutritional status, physical fitness and executive functions in preadolescents: A person-centered approach.

Objective: In the current study, a person-centered approach was adopted to investigate the relationship between nutritional status and physical fitness profiles and executive functions (EF) in preadolescents.

Methods: Participants ( = 10.8 years; Male = 50.

Effect of isometric handgrip exercise on cognitive function: Current evidence, methodology, and safety considerations.

Cognitive function is essential for most behaviors of daily living and is a critical component in assessing the quality of life. Mounting prospective evidence supports the use of isometric handgrip exercise (IHE) as a small muscle mass practice to promote health-related outcomes in clinical and healthy populations. The aim of the present review was to systematically investigate whether IHE is effective in improving the cognitive function of adults (aged ≥18 years).

Associations of Device-Measured Physical Activity, Sedentary Behavior, and Executive Function in Preadolescents: A Latent Profile Approach.

Purpose: This study investigated the associations between physical activity (PA), sedentary behavior, and executive function in preadolescents.

Methods: One hundred and twenty preadolescents were recruited from 2 Hong Kong primary schools. PA and sedentary behavior were recorded for 7 consecutive days by accelerometer.

Digital Technology Use and Cyberbullying Among Primary School Children: Digital Literacy and Parental Mediation as Moderators.

Cyberbullying has become a critical issue in many parts of the world. Children affected by bullying in cyberspace may also experience various other problems in their daily lives, such as emotional and behavioral issues. Despite the well-documented positive correlation between digital technology use and cyberbullying experiences in adolescents, a paucity of research has explored the association between digital technology use and cyberbullying, and the extent to which digital literacy (DL) and parental mediation moderate these relationships among primary school-aged children.

Coparenting and Parental Involvement During School Transition Among Chinese Mothers and Fathers: Children's School Liking as a Moderator.

Parental involvement is a vital social resource that helps children to deal with different challenges in their learning and development in the transition period and may be a strong determinant of children's outcomes. While the role of fathers has been increasingly recognized, there has been a lack of studies examining the predictive role of mother and fathers' coparenting to parental involvement and child readiness outcomes. The purpose of this study is to examine the longitudinal association between coparenting behavior and parental involvement for parents with children in the transition to primary school in a Chinese context, and test whether children's school liking moderated these associations.

Long non-coding RNA T-cell leukemia/lymphoma 6 serves as a sponge for miR-21 modulating the cell proliferation of retinoblastoma through PTEN.

Retinoblastoma (Rb) is one of the most common eye malignancies occur in childhood. The crucial roles of non-coding RNAs, particularly long non-coding RNAs (lncRNAs) and microRNAs (miRNAs), have been widely reported in Rb progression. In the present study, we found the expression of lncRNA T-cell leukemia/lymphoma 6 (TCL6) was significantly downregulated in Rb tissues and cell lines.
