Correlates of Moderate-to-Vigorous Physical Activity Among Prepubertal Girls: A Bioecological Approach.

Objective: This study aimed to analyze the correlates of moderate-to-vigorous physical activity (MVPA) among prepubertal girls using a broad spectrum of variables, including biological factors, behavioral attributes, and maternal and built environmental factors.

Methods: The sample was comprised of 81 girls, aged 7.50-9.

Improving Motor Competence of Children: The "Super Quinas" Intervention Program in Portuguese Primary Schools.

Objectives: The objective of this study was to describe the effects of an extra hour of a structured motor program on the motor competence (MC) of children 6-10 years old..

Design: The need for movement interventions to enhance MC among school-aged children has gained vital importance in the last years, given the negative secular trends reported.

Multiple physiological response analyses of Chlorella vulgaris exposed to silver nanoparticles, ciprofloxacin, and their combination.

The combination of silver nanoparticles (AgNPs) and ciprofloxacin (CIP) can be considered an alternative to combat multidrug-resistant microbial infections. However, knowledge about their combined toxicity is scarce after being released in an aquatic environment. The present study evaluated the individual toxicity of AgNPs and CIP and their combined toxicity on the unicellular green microalga Chlorella vulgaris, evaluating cellular responses and conducting metabolomic analysis.

Improving Soybean Germination and Nodule Development with Nitric Oxide-Releasing Polymeric Nanoparticles.

Nitric oxide (NO) is a multifunctional signaling molecule in plants, playing key roles in germination, microbial symbiosis, and nodule formation. However, its instability requires innovative approaches, such as using nanoencapsulated NO donors, to prolong its effects. This study evaluated the impact of treating soybean () seeds with the NO donor S-nitrosoglutathione (GSNO), encapsulated in polymeric nanoparticles, on the germination, nodulation, and plant growth.

The Influence of Including Goalkeepers on the Intensity Demands of Walking Football Practice.

This preliminary study examined the effects of playing walking football with and without a goalkeeper (GK) on physiological, physical, technical, and perceptual variables in older men. Twenty participants (67 ± 4.7 years) engaged in two five vs.
