Table_1_Autonomous motivation, social support, and physical activity in school children: moderating effects of school-based rope skipping sports participation.DOCX
PurposeRecent studies have shown that physical activity (PA) levels are low among children and adolescents globally. In order to reverse this trend, PA interventions are increasingly favoured. The school setting is the ideal place to address the issues that many children face. The purpose of this study was to (a) The primary focus of this study is to delve into the mediating role played by school-based rope skipping sports participation (SRSP) in the connection between social support and moderate to high-intensity physical activity (MVPA) among school children. (b) Additionally, this research aims to examine the moderating effect of within this pathway.MethodsWe conducted a survey involving 721 adolescents residing in Changsha City. The participants’ ages ranged from 8 to 12 years, with an average age of 9.84 ± 1.535 years. Out of these participants, 406 were boys, and 315 were girls. To assess variables such as social support and autonomous motivation, we employed standardized measurement scales. Subsequently, we analyzed the collected data using various statistical methods, including independent s-amples t-tests, bivariate correlation analysis, descriptive statistical analysis, structural equation modeling (SEM), and the Johnson-Neyman method.ResultsAn independent samples t-test revealed a statistically significant difference in MVPA between genders (p = 0.003 ConclusionSocial support and autonomy support have been proven effective in enhancing school children’s engagement in MVPA. They exert their influence indirectly by fostering autonomous motivation. Notably, robust social support can significantly benefit MVPA school children with high activity requirements, particularly those regularly engaged in MVPA during the school day.</p
The expression level of some key enzymes involved in the ‘arginine and proline metabolism’ pathway during cold acclimation.
<p>Both the up-regulated expression of OAT (ornithine-oxo-acid transaminase), P5CS (pyrroline-5-carboxylatesynthase), ProTp (proline transporter), ProRK (proline-rich receptor protein kinase), P5CR (pyrroline-5-carboxylate reductase), and the down-regulated expression of ProDH (proline dehydrogenase), P4HO (prolyl 4-hydroxylase), OCD (ornithine cyclodeaminase) could result in proline accumulation.</p
Comparative Transcriptomic Analysis of the Response to Cold Acclimation in <i>Eucalyptus dunnii</i>
<div><p><i>Eucalyptus dunnii</i> is an important macrophanerophyte with high economic value. However, low temperature stress limits its productivity and distribution. To study the cold response mechanisms of <i>E. dunnii</i>, 5 cDNA libraries were constructed from mRNA extracted from leaves exposed to cold stress for varying lengths of time and were evaluated by RNA-Seq analysis. The assembly of the Illumina datasets was optimized using various assembly programs and parameters. The final optimized assembly generated 205,325 transcripts with an average length of 1,701 bp and N50 of 2,627 bp, representing 349.38 Mb of the <i>E. dunnii</i> transcriptome. Among these transcripts, 134,358 transcripts (65.4%) were annotated in the Nr database. According to the differential analysis results, most transcripts were up-regulated as the cold stress prolonging, suggesting that these transcripts may be involved in the response to cold stress. In addition, the cold-relevant GO categories, such as ‘response to stress’ and ‘translational initiation’, were the markedly enriched GO terms. The assembly of the <i>E. dunnii</i> gene index and the GO classification performed in this study will serve as useful genomic resources for the genetic improvement of <i>E. dunnii</i> and also provide insights into the molecular mechanisms of cold acclimation in <i>E. dunnii</i>.</p></div
Cu-Catalyzed Consecutive Hydroxylation and Aerobic Oxidative Cycloetherification under Microwave Conditions: Entry to 2‑Arylbenzofuran-3-carboxylic Acids
A convenient one-pot
synthesis of 2-arylbenzofuran-3-carboxylic
acids from (<i>E</i>)-2-(2-bromophenyl)-3-phenylacrylic
acids via Cu-catalyzed consecutive hydroxylation and aerobic oxidative
cycloetherification under microwave conditions has been developed.
This protocol employed the reagent combination of CuÂ(OAc)<sub>2</sub>, 1,10-phen, and KOH in DMSO/H<sub>2</sub>O (1:1), all of which are
cost-effective, readily available, and easily removable from the reaction
mixture. Utilizing this synthetic protocol, various 2-arylbenzofuran-3-carboxylic
acids as well as the natural product moracin M have been synthesized
in satisfactory yields under mild conditions

Fracture properties and response surface methodology model of alkali-slag concrete under freeze-thaw cycles.pdf
<p>In this paper, response surface
methodology is used to study alkali-slag concrete(ASC) fracture toughness; the influence on fracture
toughness from high to low is slag content, age and sol ratio, the interaction
of slag content and age is the most significant; initiation fracture toughness
is about 50%~70% of unstable fracture toughness, crack initiation should be the
warning indicator of ASC structure; fracture toughness decreases with
freeze-thaw times increasing, its declining rate and degree increase with sol
ratio and slag content; increase of sol ratio reduces internal density and hinders
depolymerization. Cementitious material content reduces ASC toughness.</p
