Published: May 2024

BackgroundLong-term skill learning can lead to structure and function changes in the brain. Different sports can trigger neuroplasticity in distinct brain regions. Volleyball, as one of the most popular team sports, heavily relies on individual abilities such as perception and prediction for high-level athletes to excel. However, the specific brain mechanisms that contribute to the superior performance of volleyball athletes compared to non-athletes remain unclear.MethodWe conducted a study involving the recruitment of ten female volleyball athletes and ten regular female college students, forming the athlete and novice groups, respectively. Comprehensive behavioral assessments, including Functional Movement Screen and audio-visual reaction time tests, were administered to both groups. Additionally, resting-state magnetic resonance imaging (MRI) data were acquired for both groups. Subsequently, we conducted in-depth analyses, focusing on the amplitude of low-frequency fluctuations (ALFF), regional homogeneity (ReHo), and functional connectivity (FC) in the brain for both the athlete and novice groups.ResultsNo significant differences were observed in the behavioral data between the two groups. However, the athlete group exhibited noteworthy enhancements in both the ALFF and ReHo within the visual cortex compared to the novice group. Moreover, the functional connectivity between the visual cortex and key brain regions, including the left primary sensory cortex, left supplementary motor cortex, right insula, left superior temporal gyrus, and left inferior parietal lobule, was notably stronger in the athlete group than in the novice group.ConclusionThis study has unveiled the remarkable impact of volleyball athletes on various brain functions related to vision, movement, and cognition. It indicates that volleyball, as a team-based competitive activity, fosters the advancement of visual, cognitive, and motor skills. These findings lend additional support to the early cultivation of sports talents and the comprehensive development of adolescents. Furthermore, they offer fresh perspectives on preventing and treating movement-related disorders.

Age-dependent changes in plasma concentrations of 25-hydroxyvitamin D may complicate vitamin D status assessment of immature cats
Authors: Backus Robert C. , Ueda Devon C. 
Published: May 2024

BackgroundVitamin D deficiency and excess in clinically presented cats conventionally is diagnosed by comparison of patient plasma 25-hydroxyvitamin D (25 (OH)D) concentration with plasma reference intervals determined in healthy adult cats. For immature cats, validity of this vitamin D status assessment method is uncertain.ObjectiveThe overall objective was determination of whether plasma concentration of 25 (OH) D and other vitamin D metabolites in immature cats markedly change with developmental age as has been reported in other species.MethodsFour male and 4 female domestic short-hair kittens from weaning were continuously presented a single nutritionally adequate growth-diet. Concentrations of 25 (OH) D and 24,25-dihydroxyvitamin D (24,25 (OH)2D), and calcitriol were quantified in plasma of jugular venous blood collected at 12, 15, 18, and 21 weeks and 1 year of age. Plasma was liquid and solid-phase extracted and fractionation by normal-phase HPLC, and 25 (OH) D and 24,25 OH)2D quantified by reverse-phase HPLC-UV and calcitriol by RIA.ResultsPlasma 3-epi-25 (OH) D and 25 (OH) D concentrations increased (p &lt; 0.001) with age so that by study end the concentrations rose by 1-and 2-fold, respectively. Concentrations of 3-epi-25 (OH) D relative to 25 (OH) D were 30% at 12 weeks and 20% at 1 year. Between ages 12 and 21 weeks, rises in 25 (OH) D concentration were positively correlated with body weight gains (ρ = 0.952, p &lt; 0.001) and 24,25 (OH)2D concentrations were consistently greater than 25 (OH) D concentrations (p &lt; 0.001). At 1 year of age, concentrations of 24,25 (OH)2D declined below those of 25 (OH) D and 3-epi-24,25 (OH)2D consistency occurred in low concentrations. Vitamin D2 metabolites and sex differences in metabolite concentrations were not observed.ConclusionReliance on quantification of plasma 25 (OH) D concentration for vitamin D status assessment in kittens may be confounded by developmental changes in 25 (OH) D independent of vitamin D intake. High 24,25 (OH)2D concentration and occurrence of 3-epi-25 (OH) D in plasma additionally may interfere with the quantification.

Authors: Amasha Edippuli Arachchige Dona Hiruni , Kandiah Mathivathani 
Published: May 2024

The biological synthesis of nanoparticles using plants or microorganisms has gained attention in the recent past, mainly due to its eco-friendly nature and because they can be used in a vast variety of fields such as medicine, agriculture and textiles. The current study focuses on the green synthesis of silver nanoparticles (AgNPs) using five varieties of Cordyline fruticosa (candy cane, waihee rainbow, exotica, pink cascade and pink diamond) leaves, and assessing their antioxidant, photocatalytic and antimicrobial activities. SEM analysis of pink cascade-AgNPs shows they are spherical and in the range of 40-50nm. Band gap energy calculations reveal that synthesized AgNPs can act as semiconductors. Total flavonoid content, total phenolic content and total antioxidant capacity were analyzed and the DPPH-free radical scavenging assay was performed. These showed that AgNPs had higher antioxidant activity compared to aqueous extracts. The antibacterial activity of AgNPs and aqueous extracts was assessed using cultures of Escherichia coli and Staphylococcus aureus. Extracts and AgNPs showed better bactericidal effect on S.aureus. Photocatalytic activity of synthesized AgNPs was assessed using malachite green as a model dye and significant degradation of the dye was observed when AgNPs were added together with catalyst NaBH4. According to the results obtained from this study, it can be seen that AgNPs synthesized using Cordyline fruticosa have potential in different aspects including treatment of free-radical mediated diseases, overcoming antibiotic resistance, treatment of bacterial diseases and overcoming environmental pollution.
Introduction to Special Issue: Centering Community Healing, Sustenance, and Resilience in STEM and Computing Education Through Art and Social Justice

Published: May 2024

Computing, technology, and engineering education are in particular need of examining how we can bring love, community, and joy to the center of learning experiences to support a diversity of youth to flourish. Computing and STEM disciplines are often taught in ways that detach knowledge from people and communities, making it difficult to explore a variety of personal, social, and societal connections that are not already at the center of the tech industry. These exclusionary practices limit the way work is accomplished—including who is involved in the design work and who technological innovations are designed for; as well as the way the work is situated within our society—including what problems technology is designed to solve and who benefits from particular innovations (Benjamin, 2019; Noble, 2018). Learning experiences and spaces for technology education should support youth as they develop new knowledge and skills in ways that recognize them as full humans, and enable them to ground it in their ideas, perspectives, interests, goals, identities, communities, relationships, and local environments. The goal of this special issue is to bring together educators’, researchers’, and youth voices in conversation about how we are centering self-empowerment in our educational work and how we can drive forward our practices.

Abstract
This study investigates the effects of sulfur atomic defects and crystallinity on the thermal conductivity of MoS2 thin films. Utilizing scanning transmission electron microscopy (STEM), X-ray diffraction (XRD), and Raman spectroscopy, we examined MoS2 films, several nanometers thick, deposited on Si/SiO2 substrates. These films were prepared via a combination of RF magnetron sputtering and sulfur vapor annealing (SVA) treatment. Structural analyses, including cross-sectional STEM and in-plane and out-of-plane XRD measurements, revealed an increase in the S/Mo ratio and grain size of the MoS2 films following SVA treatment. Notably, the in-plane thermal conductivity of MoS2 films treated with SVA was found to be at least an order of magnitude higher than that of films without SVA treatment. This research suggests that the in-plane thermal conductivity of MoS2 thin films can be significantly enhanced through crystallinity improvement via SVA treatment.

Abstract
By imaging a capacitively coupled plasma from multiple directions using telecentric lens cameras and optical bandpass filters, the spatial structure of emission at specific wavelengths was reconstructed using the Tikhonov–Phillips regularization method. Camera parameters, crucial for relating three-dimensional structures to two-dimensional images, were evaluated experimentally to avoid a complex analytical approach. Assuming an axisymmetric emission profile, 750.4 nm Ar and 585.2 nm Ne emissions from Ar/Ne mixture plasma were reconstructed. The pressure dependence of the reconstructed Ar profile showed a similar trend to that of the two-dimensional emission images. The spatial structure of the emission intensity ratio of Ne to Ar from the reconstructed Ar and Ne profiles agreed well with a spatial distribution of electron temperatures measured with a Langmuir probe.

Abstract
With the rapid development of fifth-generation communication technology, there are more and more 5 G frequency bands and their bandwidths differ. Therefore, many researchers devote themselves to the study of resonators with adjustable electromechanical coupling coefficient. In this paper, we apply composite films to the Lamb wave resonator with a double-IDT configuration to achieve adjustable effective electromechanical coupling coefficient (Keff

2) of the first symmetric mode. The experimental results show that with the increase of the thickness ratio, the series resonant frequency (

fs

) of the resonator decreases from 2.567 GHz to 2.333 GHz; and the parallel resonant frequency (

fp

) of the resonator decreases from 2.608 GHz to 2.396 GHz. The Keff
2 is adjusted from 3.82% to 6.32% and the Δf (

fp
−
fs

) is adjusted from 41 to 63 MHz by using the AlN/Sc0.096Al0.904N composite films with different thickness ratios. This method may be an efficient way to adjust the bandwidth of the filter to meet the needs of different frequency bands.

Abstract
The simulation of advanced synaptic functions of the human brain by electrical devices could be an effective strategy for constructing high-efficiency neuromorphic systems. Two-dimensional (2D) materials are promising candidates in the fabrication of optoelectronic devices due to their excellent photoelectric performances. Herein, opto-electronic synapses based on layered MoS2/SnSe2 van der Waals heterojunction(vdwH) memtransistors have been investigated. It can be observed that the typical synaptic functions, such as excitatory/inhibitory postsynaptic current, long-term potentiation/depression, paired-pulse facilitation/depression (PPF/PPD), as well as the transition from short-term memory (STM)to long-term memory (LTM) are realized using both electrical and optical pulses as input signals. In addition, the time constant for PPF under optical pulses was 3.91 s, which was comparable with the response times of biological neural synapses. So the MoS2/SnSe2 memtransistor could work as an electronic synapse in future artificial neural networks, inspiring the implementation of 2D materials for neuromorphic storage and computation.

A doença cárie é tida como um grande problema de saúde bucal em todo o mundo. Dessa forma, é caracterizada como uma doença comportamental diretamente ligada a hábitos alimentares, e a falta de higienização efetiva. A odontologia trabalha em busca de diminuir procedimentos invasivos, como as intervenções operatórias cuja intenção é favorecer um ambiente onde ocorra a paralisação da atividade cariogênica. Portanto, a remoção parcial do tecido cariado é considerada uma ótima opção quando a ideia é um tratamento que visa reabilitação estética e funcional do paciente, atrelado a promoção de saúde bucal1. E é um procedimento realizado de forma menos invasiva e com menos estresse ao paciente odontopediátrico. O objetivo desse trabalho é realizar uma revisão de literatura, tendo como a finalidade de se ampliar o conhecimento á respeito da remoção seletiva do tecido cariado em dentes decíduos e sobre a utilização da técnica de coroa metálica de hall technique. Tratamentos minimamente invasivos que removem o tecido cariado infectado, preservando tecidos afetados, e utilizam materiais de alta viscosidade com liberação de flúor como o cimento de ionômero de vidro tem demonstrado bons resultados na manutenção e prevenção da progressão da cárie dentária. O presente estudo se trata de uma revisão narrativa da literatura, que considera artigos de revisão, relato de caso clínico, monografias e capítulos de livros publicados nas bases de dados Medline, Lilacs, Scielo e Google Acadêmico.
