Relationship Between Physical Literacy and Cardiorespiratory Fitness in Children and Adolescents: A Systematic Review and Meta-analysis.

Background: Physical literacy (PL) can positively affect the health of children, adolescents, and adults, and is closely related to cardiorespiratory fitness (CRF).

Objective: To perform a systematic review and meta-analysis to examine the relationship between overall physical literacy (PL) and CRF in children and adolescents.

Methods: Cross-sectional, cohort and experimental studies on the relationship between PL and CRF in children and adolescents were collected by searching the Web of Science Core Collection, PubMed, EBSCOhost, ScienceDirect, Cochrane Library and China National Knowledge Infrastructure (CNKI) databases.

Integrated analysis of transcriptome and proteome reveals a core set of genes involved in osteoblast under oxidative stress.

Osteoblasts dysfunction, induced by oxidative stress (OS), is a significant contributor to the pathogenesis of osteoporosis. However, the genes implicated in regulating osteoblast dysfunction remain unclear. Here, we employed the hydrogen peroxide (HO)-induced osteoblast dysfunction model to assess its impact on osteoblast phenotype and to conduct transcriptome and proteome analyses in osteoblasts under OS.

Role of the PGAM5-CypD mitochondrial pathway in methylglyoxal-induced bone loss in diabetic osteoporosis.

Diabetic osteoporosis (DOP) is a skeletal complication with a high rate of disability. It results in a great burden to the patient's family and society. Methylglyoxal (MG) is a toxic by-product of the glycolytic process that occurs during diabetic conditions.

Structured-unstructured activity behaviours on preschoolers' mental and physical health: a compositional and isotemporal reallocation analysis.

This study analysed the relationship between the structured and unstructured activities of preschoolers and their mental and physical health, and also investigated the predicted changes in mental and physical health by reallocating activity time. This cross-sectional study was carried out with 324 preschoolers. Video recording and SOPARC activity observation system was used for the division of structured and unstructured activities.

Synthesis and Antiosteoporotic Characterization of Diselenyl Maleimides: Discovery of a Potent Agent for the Treatment of Osteoporosis by Targeting RANKL.

To discover new osteoclast-targeting antiosteoporosis agents, we identified forty-six diselenyl maleimides, which were efficiently prepared using a novel, simple, and metal-free method at room temperature in a short reaction time. Among them, showed the most marked inhibition of osteoclast differentiation with an value of 0.36 ± 0.

Effects of structured and unstructured interventions on fundamental motor skills in preschool children: a meta-analysis.

Background: It has been suggested that higher levels of fundamental motor skills (FMS) promote the physical health of preschool-aged children. The impacts of structured and unstructured interventions on FMS in children aged 10-16 years have been widely acknowledged in previous studies. However, there is a lack of relevant studies in preschool-aged children.

The "supercompensation" effect of children's lockdown during COVID-19: based on the analysis of changes in physical activity, sleep, and psychology.

Objective: To investigate the "supercompensation" effect of preschoolers during the coronavirus disease 2019 lockdown by comparing the changes in physical activity (PA), psychological, and sleep indicators before and after the lockdown.

Methods: A total of 127 children (aged 3-6 years) were recruited. Before and after the lockdown, the children's PA levels were measured using the ActiGraph GT3X, and their psychological and sleep indicators were measured using the Strengths and Difficulties Questionnaire (SDQ) and Child Sleep Habit Questionnaire (CSHQ), respectively.

Relationship between 24-h activity behavior and body fat percentage in preschool children: based on compositional data and isotemporal substitution analysis.

Objective: This study aims to elucidate the dose‒response relationship between 24-h activity behaviors and body fat percentage (BFP) in Chinese preschool children using a compositional isotemporal substitution model (ISM).

Methods: In a cross-sectional design, 881 children aged 3-6 from urban and rural areas of Jiangxi Province were sampled. Activity behaviors, including sedentary behavior (SB), low-intensity physical activity (LPA), and moderate- to high-intensity physical activity (MVPA), were measured using accelerometers.

Effects of Traditional Chinese Exercise on Oxidative Stress in Middle-Aged and Older Adults: A Network Meta-Analysis.

Objective: To evaluate the best option among traditional Chinese exercises for reducing oxidative stress in middle-aged and older adults, using a network meta-analysis.

Methods: PubMed, Web of Science, and CNKI databases were used. We searched randomized controlled trials (RCTs) on middle-aged and older adults to influence oxidative stress by any traditional Chinese exercises from the beginning to 20 January 2022.

[Effects of different maintain doses of dexmedetomidine on plasma cortisol and glucose during anesthesia recovery period in patients undergoing uvulopalatopharyngoplasty under sevoflurane inhalation anesthesia].

Objective: To observe the effects of different maintain doses of Dexmedetomidine on plasma cortisol and glucose during anesthesia recovery period in patients undergoing uvulopalatopharyngoplasty under sevoflurane inhalation anesthesia.

Method: In this prospective, randomized, double-blind study, 120 ASA I and II patients undergoing selective uvulopalatopharyngoplasty under general anesthesia were included. The patients were randomly allocated to three groups (n = 40): Dexmedetomidine low maintain dose group (D1), Dexmedetomidine high maintain dose group (group D2) and control group (group C).
