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.

[Tc]Technetium and Rhenium Dithiocarbazate Complexes: Chemical Synthesis and Biological Assessment.

Background/objectives: Dithiocarbazates (DTCs) and their metal complexes have been studied regarding their property as anticancer activities. In this work, using S-benzyl-5-hydroxy-3-methyl-5-phenyl-4,5-dihydro-1H-pirazol-1-carbodithionate (Hbdtc), we prepared [ReO(bdtc)(Hbdtc)] and [[Tc]TcO(bdtc)(Hbdtc)] complexes for tumor uptake and animal biodistribution studies.

Methods: Re complex was prepared by a reaction of H2bdtc and (NBu)[ReOCl], the final product was characterized by IR, H NMR, CHN, and MS-ESI.

Bee pollen from bracatinga (Mimosa scabrella): Effects of gastrointestinal digestion and epithelial transport in vitro on phenolic profile and bioactivities.

The main objective of the present work was to assess the phenolic profile of bracatinga (Mimosa scabrella) bee pollen, and its antioxidant and anti-inflammatory activities after gastrointestinal digestion in vitro and epithelial transport in a Caco-2 cell monolayer model. The botanical origin of bee pollen was confirmed by optical microscopy and scanning electron microscopy. As major results, 34 phenolic compounds (13 phenylamides, 14 flavonols, and 7 flavanones) were tentatively identified in the extract of bracatinga bee pollen by HPLC-ESI-QTOF-MS.

Motor Competence and Difficulty of Self-Set Goals on Motor Learning.

Motor competence is associated with the perceived difficulty of a task. This study hypothesized that children with higher motor competence perceive certain tasks as less challenging than their peers with lower motor competence. As a result, children with higher motor competence were expected to set more ambitious goals for themselves while learning a new task compared to children with lower motor competence.
