Children's fundamental movement skills (FMS) require planned and guided interventions to develop appropriately. We investigated the effect of a novel Physical Education (PE) method to develop children's object control, locomotor skills, and motor competence. Further, we examined children's trainability, i.

Objective: Emergency contraception serves as the only dependable method for women to prevent pregnancy following unprotected sex. Among emergency contraception methods, the copper intrauterine device provides continuous, highly effective contraception for over a decade. This study aimed to evaluate the effectiveness, safety, and side effects of the copper intrauterine device over methods containing levonorgestrel for emergency contraception.

Purpose: The purpose of this paper is to present a scale that assesses students' perceptions of their engagement in physical education. The scale assesses all four dimensions of engagement (agentic, cognitive, behavioral, and emotional) in order to be consistent with the contemporary notion of engagement used in current educational research.
Method: A total of 231 eighth and ninth-grade students (108 boys, Mage = 14.
Article Synopsis
- Dissolved organic carbon (DOC) plays a crucial role in the carbon cycle of the Southern Ocean, but understanding its dynamics in polar regions remains limited.
- Researchers focused on the northern Antarctic Peninsula (NAP) between 1995 and 2019, finding DOC concentrations ranged from 33.1 to 157.6 μmol kg-1 and highlighting regional differences in DOC due to various water currents and meltwater inputs.
- The study revealed that advective fluxes of DOC are significantly stronger than diffusive fluxes, underscoring the importance of ocean fronts for observing DOC movements and indicating the need to understand its role in biogeochemical processes, especially in the context of climate change.
Objective: Obesity is associated with liver depletion of ω-3 polyunsaturated fatty acids (ω-3 PUFAS) promoting steatosis and inflammation, whose levels are maintained by diet or biosynthesis involving Δ-5D, Δ-6D desaturases and elongases.
Method: We aimed to assess Δ-5D and Δ-6D activities in liver and brain from mice fed a control diet (CD) or high-fat diet (HFD) for four to sixteen weeks.
Results: HFD led to (1) an early (4 weeks) enhancement in liver Δ-5D, Δ-6D, and PPAR-α activities, without changes in oxidative stress, liver damage or fat accumulation; (2) a latter progressive loss in hepatic desaturation with insufficient compensatory increases in mRNA and protein expression, leading to ω-3 PUFA depletion, PPAR-α down-regulation reducing FA oxidation, and liver steatosis with enhancement in lipogenesis; and (3) brain ω-3 PUFA depletion after 12 to 16 weeks of HFD feeding.
