ObjectiveExtreme sport participation is growing, yet it is still not clear exactly what motivates individuals to participate in sports where accidents can lead to serious injury or death. The purpose of this systematic review was to review and assess current research and identify the factors that explain engagement in extreme sport participation.MethodsA systematic review of PsycInfo, ProQuest, PsychArticles, SportDiscus and Google Scholar was performed according to PRISMA guidelines. Eligibility criteria were defined to identify studies exploring the factors that explain or are associated with taking part in extreme sports. Articles published in English in peer-reviewed journals were retrieved.ResultsA total of 35 studies met the eligibility criteria. The sample comprised 17 qualitative studies, 12 quantitative studies, 5 case studies and 1 mixed method study. Findings were categorised into five key themes; “existential and external” (external reasons for participation, e.g., being in nature), “personality” (i.e., stable traits that predicted participation e.g., sensation seeking), “motivation characteristics” (i.e., one's capability and confidence whilst participating, e.g., self-determination theory), “managing risk” (i.e., explanation centred around the desire to take risks e.g., experiential vs. analytical) and “analogies with addiction and withdrawal” (i.e., the behavioural response experienced whilst abstaining from/unable to take part in the sport e.g., craving).ConclusionThere are multiple reasons why individuals participate in extreme sports despite their inherent danger. This review highlights how individuals differing perceptions of risk can impact motivations and therefore the complexity in this area. Potential links between themes and suggestions for future research are also discussed.Systematic Review Registrationhttps://osf.io/mvk2j.

Published: July 2024

A Síndrome Dolorosa Regional Complexa (SDRC), antigamente chamada de Distrofia Simpático Reflexa e de Causalgia, consiste em uma condição de dor crônica. Essa Síndrome é caracterizada por uma dor contínua, progressiva, regional, que afeta predominantemente as partes distais de uma extremidade e é precedida de uma lesão traumática ou de outra lesão. O presente artigo visou como objetivo analisar a Dor Neuropática na SDRC. Como metodologia, foi produzida uma pesquisa descritiva do tipo revisão de literatura integrativa. Assim, esta pesquisa baseou-se em uma análise de artigos selecionados das bases de dados Pubmed e Medline , publicados entre o período de 2018 a 2023. Foram utilizados para a busca os descritores "complex regional pain syndromes"; "dor crônica"; "manejo da dor". A partir dos achados, foram reunidos 17 artigos organizados segundo o critério PRISMA, que serviu de ferramenta de verificação e pontuação de credibilidade das fontes utilizadas. Como critério de elegibilidade, foram aplicados apenas trabalhos científicos completos, em língua inglesa e um em Islandês. As duplicatas e os artigos que não responderam a pergunta norteadora foram excluídos. A pesquisa possibilitou identificar os mecanismos fisiológicos da dor neuropática presente na síndrome e contribuiu para destacar a importância da prevenção, diagnóstico e tratamento. Apesar disso, há lacunas na literatura, exigindo mais pesquisas para entender completamente a SDRC. Logo, essa temática mostra-se relevante, quando analisamos que é necessária uma abordagem multidisciplinar para o manejo eficaz da SDRC, para um diagnóstico precoce, bem como pela necessidade de melhorar as intervenções e qualidade de vida dos pacientes.

Published: July 2024

Introdução: O elevado número de infecções por COVID 19 em um curto período ocasionou uma crise sanitária no sistema de saúde brasileiro e trouxe impactos significativos em diversos setores da economia. Com isso, uma das alternativas para tentar atenuar os efeitos da pandemia foi o Plano Nacional de Operacionalização da Vacinação Contra a COVID-19 (PNOVC), estratégia de vacinação do Programa Nacional de Imunizações contra a COVID-19, com definição de público alvo. A divisão dos grupos prioritários, por sua vez, foi pautada no risco de desenvolvimento de um quadro mais grave da doença (Kemp,2020). Há a possibilidade de desenvolvimento de efeitos reacionais após a aplicação dos imunizantes, portanto uma compreensão melhor acerca de quais são essas complicações, em quais grupos de indivíduos elas se concentram, sua frequência e intensidade, bem como outras informações, como o tipo da vacina, se fazem necessárias, representando um potencial de obtenção de dados extremamente relevantes. Objetivo: Analisar os fatores que influenciam o grau dos efeitos colaterais das vacinas oferecidas pelo Programa Nacional de Imunizações (PNI). Metodologia: Foi realizado um estudo quantitativo, inserido nas ciências da saúde, a respeito das reações adversas provocadas pelas vacinas contra a COVID-19 disponíveis no Brasil. Foram considerados eventos adversos provenientes da vacina aqueles que se manifestarem até 72 horas após a aplicação (Brasil,2014). Como instrumento de coleta, foi utilizado um formulário, distribuído de maneira aleatória, a fim de selecionar as pessoas que se enquadram nos critérios de inclusão. Resultados e conclusões: A partir da observação dos dados coletados, foi notado que há uma redução do aparecimento de efeitos colaterais na população mais idosa, em mulheres e em pessoas com comorbidades em relação aos jovens, homens e pessoas com comorbidades, respectivamente (APS,2018). Aparentemente, há uma relação entre essa população com um déficit no sistema imune (Kemp,2020), mas para qualquer afirmação, novos e maiores estudos são necessários. Além disso, não ficou claro se a grande quantidade de participantes que tomaram a CoronaVac assintomáticos no pós-aplicação está relacionado com a idade mais avançada da população que tomou esta vacina ou com a vacina em si, já que que a idade mais avançada apareceu, neste estudo, com menos efeitos adversos em relação à aplicação das vacinas.

Hormone replacement therapy (HRT) has been a primary method in menopausal women and patients with ablated ovaries, but safety has been a concern. Cell-based HRT has emerged as an alternative approach without side effects causing pharmaceutical HRT via 3-dimensionally engineered constructs layering ovarian hormone-producing cells. In this study, we applied micro-sized ovarian cell-laden hydrogel beads as an approach to cell-based HRT using a minimally invasive method in the menopausal rat model. Here, we constructed GC/TC-laden microbeads (GTBs; GC, granulosa cell; TC, theca cell) that allow crosstalk between endocrine cells, encapsulating multiple beads for the figuration of the original ovary. We assessed the ovarian hormone production function of GTB through in vitro culture for 90 days. We applied it to a menopausal rat model and confirmed that GTB-injected rats restored their endocrine function, leading to the regeneration of the thinned endometrium and the maintenance of regular estrous cycles in some individuals. Additionally, it was observed to alleviate menopausal symptoms, including body weight gain and osteoporosis. Notably, the GTB-injected rats did not show mammary gland hyperplasia observed in the pharmaceutical HRT groups and exhibited fewer p53- and KI67-positive and an increase in phosphatase and tensin homolog-positive mammary gland epithelial cells compared to pharmaceutical hormone-treated rats. These results suggest that GTB-based HRT could present a lower risk of breast cancer compared to conventional pharmaceutical-HRT use. Our study highlights the potential of cell-based HRT using an injectable artificial ovary, offering a safer alternative for women requiring HRT.

Abstract
In this research, we have investigated the effect of excimer laser annealing (ELA) on the ferroelectric nondoped HfO2 (FeND-HfO2) formation deposited on a Si(100) substrate. The XeCl (λ: 308 nm) ELA was irradiated as post-deposition annealing (PDA) in the N2 ambient to the 10 nm thick HfO2 deposited by RF-magnetron sputtering without substrate heating. The C–V characteristics of Al/HfO2/p-Si(100) metal/ferroelectrics/Si (MFS) diodes were gradually improved with the energy density of ELS from 170 mJ cm−2 to 270 mJ cm−2 irradiated at 200 Hz for 200 shots although the charge-injection type hysteresis of 0.2–0.3 V remained. The post-metallization annealing (PMA) at 400 °C/5 min in N2/4.9%H2 ambient for Al/HfO2/p-Si(100) MFS diodes markedly improved the C–V characteristics, and negligible hysteresis with ideal flat-band voltage (V
FB) was realized. The memory window (MW) of 0.42 V was achieved by the program/erase (P/E) operation with the input pulses of +3 V/100 ms and −8 V/100 ms for the MFS diode with an ELA energy density of 270 mJ cm−2 at 200 Hz for 200 shots followed by the PMA.

Published: July 2024

Abstract
Free electron mobility (μ
free) in 4H-SiC(0001) MOSFETs with gate oxides annealed in NO or POCl3 was calculated in a wide range of effective normal field (E
eff) from 0.02 to 2 MV cm−1, taking account of scattering by fixed charges and trapped electrons. The present calculation indicates that the Hall mobility in the high-E
eff region experimentally obtained for NO-annealed MOSFETs (14 cm2 V−1 s−1 at 1.1 MV cm−1) is much lower than that for POCl3-annealed MOSFETs (41 cm2 V−1 s−1) due to severe Coulomb scattering by electrons trapped at a very high density of interface states.

Abstract
We analyzed the effects of a hypo-osmotic environment on rat Schwann cells, a type of glial cell surrounding neurons, using ultra-broadband multiplex coherent anti-Stokes Raman scattering (CARS) microscopy. After hypo-osmotic treatment, we detected vacuole-like components in the cytoplasm using both bright-field and CARS spectroscopic imaging. An approach integrating both morphological examination and a spectroscopic analysis based on multiple vibrational bands revealed that these structures are predominantly water-filled, and their characteristics closely resembled those of the vacuoles observed in plant cells.

Abstract
Transfer learning was examined to predict current-voltage (I-V) characteristics of MOSFETs at cryogenic temperatures. An experimental dataset was obtained from approximately 800 silicon-on-insulator MOSFETs using an automated cryogenic wafer prober to pre-train a 3-hidden-layer neural network (NN) model. Transfer learning based on the NN model was then conducted using another small dataset from 2 bulk MOSFETs. The transfer learning NN model predicted more realistic I-V characteristics and threshold voltages than a control NN model trained using only the small dataset. This study demonstrates cryogenic MOSFET characteristics prediction from a small dataset to reduce time and financial costs for developing cryo-CMOS devices.

Published: July 2024

Abstract
Graphene–graphene oxide (GO) hybrid liquid cells (LCs) for liquid-phase scanning transmission electron microscopy (STEM) were fabricated using a facile method with commercial graphene on a polymethyl methacrylate sheet and GO on a TEM grid. LCs containing Pt nanoparticles (NPs) and pure water were efficiently produced and observed via STEM. Their composition and thickness were characterized by STEM-electron energy-loss spectroscopy. High-resolution (HR) STEM revealed slow-moving Pt NPs’ atomic structures and fast-moving single Pt atoms at the LC’s thin edges. Minimal damage during HR STEM indicated stable LCs because of their excellent electrical and thermal conductivities and radiolysis species scavenging ability.

BACKGROUND. Endothelial dysfunction (ED) plays an important role in the development and progression of chronic kidney disease (CKD). However, there is insufficient information in the literature on changes in the expression of vascular wall endothelial adhesive molecules in patients with kidney disease.THE AIM: to study the content of P-selectin in the blood of patients with CKD and to evaluate its effect on the development of ED and atherosclerotic changes.PATIENTS AND METHODS. 128 patients with CKD (41% of men and 59% of women) were monitored, with an average age of 63.5±1.7 years. The diagnosis of CKD was made in accordance with the recommendations of KDIGO (2012). The concentration in serum of P-selectin was determined by solid-phase enzyme immunoassay using a set of reagents "Cloud-Clone Corp. P-selectin ELISA" (China).RESULTS. All patients were divided into 6 groups depending on the stage of CKD. In CKD C1 - C3a stage, an increase in the concentration of P-selectin in blood serum was revealed. Starting from the C3b stage of CKD, the values of P-selectin begin to decrease significantly, especially sharply at the C5d stage.CONCLUSION. An increase in the concentration of P-selectin in blood serum can serve as an indication for in-depth dynamic monitoring of coagulogram and lipidogram parameters, a decrease in the concentration of P-selectin in blood serum is highly likely to indicate adverse changes in the geometry of the arterial bed. In this regard, it is advisable to determine the pulse wave velocity and the Agatston index.
Acute effect of short-duration static stretching exercises on dynamic balance in U-14 female athletes

Published: July 2024

Purpose
The acute effects of static stretching (SS) on dynamic balance, a key fitness component that contributes to injury prevention, has been and is still a subject of significant debate. This study aimed to investigate the acute effect of short-duration SS exercises on dynamic balance following different recovery durations in youth female volleyball players.
Methods
Thirteen volunteers U-14 female players were included. Eight random assessments were carried-out on separate days. They consisted of 2D-kinematic analysis of frontal and/or sagittal balance of the center of mass (COM) displacement, velocity, and acceleration on wobble board conducted without SS, immediately after and following 2 and 10 minutes of SS.
Results
Repeated-measures ANOVA showed a significant difference between conditions in the velocity (p=0.002 to 0.049; d=0.844 to 2.200) and the acceleration (p=0.014 to 0.021; d=1.532 to 1.657) of the COM in both frontal and sagittal planes sway. Post-hoc analysis revealed decreased COM velocity (p=0.001 to 0.030; d=2.501 to 6.750) and acceleration (p=0.001 to 0.030; d=2.501 to 6.750) in the frontal plane, regardless of the recovery time. The most prominent decrease in both parameters was observed immediately after SS (p=0.001 to 0.013; d=2.907 to 6.750). However, in the sagittal balance, we observed an immediate increase in COM acceleration following SS (p<0.001; d=4.223).
Conclusions
Short-duration SS leads to improved dynamic balance, particularly on the frontal plane, with the most favorable effect observed immediately after stretching. Practically speaking, short-duration SS appears to be an effective exercise modality for inducing acute enhancements in dynamic balance among youth female volleyball players.
