Realizar a medição de grandezas físicas, tais como corrente e tensão, com precisão é de fundamental importância na área da instrumentação para automação, visto que tais medições geralmente realimentam controladores em malha fechada. De modo geral, os sinais aquisitados são de baixa intensidade. Assim, é indispensável o uso de placas de condicionamento de sinal para converter a grandeza medida em uma forma adequada aos sistemas de processamento de dados e controle. Dessa forma, a principal contribuição deste trabalho é apresentar uma metodologia para elaboração de um sistema de condicionamento de sinais para leitura de corrente, por meio de um sensor do tipo Bobina de Rogowski. Assim, espera-se que, como resultado deste trabalho, qualquer pessoa consiga reproduzir o sistema de medição bem como as placas de circuito impresso apresentadas neste documento para a correta medição de corrente. Além disso, também são apresentados, de forma didática, os passos matemáticos que atendam as especificações do projeto de instrumentação proposto.

Experimental project of a signal conditioning plate for a Rogowski coil differential current sensor
Abstract
Measurement of physical quantities, such as current and voltage, with precision is of fundamental importance in the area of instrumentation for automation, since such measurements generally feedback closed loop controllers. In general, the signals acquired have low intensity. Thus, it is essential to use signal conditioning plates to convert the measured quantity into a form suitable for data processing and control systems. Thus, the main contribution of this work is to present a methodology for the elaboration of a signal conditioning system for current reading, in a didactic way. It is expected that, as a result of this work, anyone can reproduce the measurement system, as well as the printed circuit boards presented in this document for correct current measurement. In addition, the mathematical steps that meet the specifications of the proposed instrumentation project are also presented in a didactic way.

Aim.
The aim of our work was the development and testing method of hysterectomy, which would greatly facilitate radical hysterectomy in patients who are overweight.
Materials and methods.
In the main group of supervision were included 76 women who had 0 and stage 1 prolapse by POP-Q classification and were operated under minimally invasive surgery of RPCPCM in the period from 2019 to 2020because of uterine fibroids by the method developed by us.The control group consisted of 50 women whom was performed intrafascial hysterectomy by the method of Oldridge. To study the vaginal profile marked by two indicators: the length of the vagina and the range of displacement of the proximal point of the vagina (apex), which were determined before surgery and 24 months after surgery at intervals of one year. Determining the length of the vagina was performed in the supine position, immediately determine the most proximal point of the vagina.
Results and discussion
Conclusions.
Methods of intrafascial hysterectomy using high-frequency diathermy are effective in preventing prolapse stump and shortening of the vagina. Shortening of the vagina in patients in the control group may have been caused by the degenerative processes due to serious injury of support structures and vessels of proximal vagina with the emergence in this context of inflammatory processes in the stump. Shortening of the vagina in patients operated on the proposed method was observed. Trends shortening of the vagina or prolapse at follow-up were found.

Glucose is an essential carbohydrate for the good functioning of the organism and in normal conditions it is able to maintain the glucose in adequate levels. The glucose can be measured by the portable glucometer or by the laboratory method, which is considered the standard methodology, but with disadvantages such as cost and the necessary amount of blood. The portable glucometer shows itself to be an applicable option because it is less expensive and faster. This prospective clinical study aimed to compare and evaluate the efficiency between the OneTouch UltraMini® portable monitor and the automated colorimetric method for measuring the blood glucose concentration of 48 dogs and 20 cats. The results obtained from the mean of the portable monitor and laboratory method were 87.54 mg/dL and 94.47 mg/dL for dogs, and 85.95 mg/dL and 100 mg/dL for cats, respectively. It could be concluded that the comparison between the methods showed that the portable meter represents an excellent option for measuring blood glucose in dogs and cats.

A delimitação das APPs é um requisito fundamental em diversos processos, tais como o Cadastro Ambiental Rural, o diagnóstico ambiental, o zoneamento ambiental e o Plano de Recuperação Ambiental. Porém, a implementação das definições legais das APPs não é tarefa trivial, dependendo principalmente da representação detalhada da malha hidrográfica. Este artigo aborda a integração de dados e a utilização de métodos de geoprocessamento para obtenção semi-automatizada de Áreas de Preservação Permanentes (APPs). para o município de Santa Rosa de Lima-SC.. Para delimitar as APPs ciliares através de Sistemas de Informações Geográficas, foi necessário realizar um mapa de distância para cada feição hidrográfica. A especificação da largura do buffer é dependente do tipo, largura e tamanho das feições da rede de drenagem. As APPs de nascentes foram definidas a partir 50 m, tendo como ponto central a própria nascente ou olho d’água. Para os cursos d’água, as APPs são delimitadas na faixa marginal a partir da calha regular, em projeção horizontal com larguras mínimas que variam de 30 a 500 m de largura. Ao considerar a junção de todas APPs delimitadas – nascentes/olhos d’água, cursos d’água, corpos d’água e áreas úmidas – há muitas áreas sobrepostas. Ao unir todas estas áreas, considerando-se adequadamente todas as sobreposições, a área resultante é de 10.125,04 ha, representando 50,12% da área total do município. Cerca de 76% da APP ciliar delimitada neste trabalho está devidamente coberta por vegetação florestal.

Published: November 2020

Introduction: The endocannabinoid system is involved in several diseases such as addictive disorders, schizophrenia, post-traumatic stress disorder, and eating disorders. As often mice are used as the preferred animal model in translational research, in particular when using genetically modified mice, this study aimed to provide a systematic analysis of in vivo cannabinoid type 1 (CB1) receptor ligand-binding capacity using positron emission tomography (PET) using the ligand [18F]MK-9470. We then compared the PET results with literature data from immunohistochemistry (IHC) to review the consistency between ex vivo protein expression and in vivo ligand binding.Methods: Six male C57BL/6J (6–9 weeks) mice were examined with the CB1 receptor ligand [18F]MK-9470 and small animal PET. Different brain regions were evaluated using the parameter %ID/ml. The PET results of the [18F]MK-9470 accumulation in the mouse brain were compared with immunohistochemical literature data.Results: The ligand [18F]MK-9470 was taken up into the mouse brain within 5 min after injection and exhibited slow kinetics. It accumulated highly in most parts of the brain. PET and IHC classifications were consistent for most parts of the telencephalon, while brain regions of the diencephalon, mesencephalon, and rhombencephalon were rated higher with PET than IHC.Conclusions: This preclinical [18F]MK-9470 study demonstrated the radioligand’s applicability for imaging the region-specific CB1 receptor availability in the healthy adult mouse brain and thus offers the potential to study CB1 receptor availability in pathological conditions.
Electroacupuncture Protects Cognition by Regulating Tau Phosphorylation and Glucose Metabolism via the AKT/GSK3β Signaling Pathway in Alzheimer’s Disease Model Mice

Published: November 2020

BackgroundAlzheimer’s disease (AD) is mainly manifested as a continuous and progressive decline in cognitive ability. Neurofibrillary tangles (NFTs) are pathological hallmarks of AD and due to accumulated phosphorylated Tau. Glycogen synthase kinase-3β (GSK3β), as a major Tau kinase and a downstream target of the serine protein kinase B (AKT) signaling pathway, can regulate Tau phosphorylation in AD. Importantly, the AKT/GSK3β signaling pathway is involved in glucose metabolism, and abnormal glucose metabolism is found in the AD brain. Numerous studies have shown that electroacupuncture (EA), which is thought to be a potential complementary therapeutic approach for AD, can protect cognitive ability to a certain extent.ObjectiveThe purpose of this experiment was to investigate whether the protective and beneficial mechanism of EA on cognition was mediated by the AKT/GSK3β signaling pathway, thereby improving glucose metabolism and Tau phosphorylation in the brain.MethodsEA was applied to the Baihui (GV20) and Yintang (GV29) acupoints of 6-month-old amyloid precursor protein (APP)/presenilin-1 (PS1) mice for 20 min, and then quickly prick Shuigou (GV26) acupoint. The intervention was performed once every other day for 28 days. The Morris water maze (MWM) test was performed on C57BL/6N (Non-Tg) mice, APP/PS1 (Tg) mice and EA-treated Tg (Tg + EA) mice to evaluate the effect of EA therapy on cognitive function. 18F-FDG positron emission tomography (PET), immunohistochemistry, and western blotting (WB) were used to investigate the possible mechanism underlying the effect of EA on AD.ResultsEA treatment significantly improved the cognition of APP/PS1 mice and the glucose uptake rate in the hippocampus. Furthermore, EA inhibited the phosphorylation of Tau (Ser199 and Ser202) proteins by inducing AKT (Ser473) and GSK3β (Ser9) phosphorylation.ConclusionThese results demonstrate that EA intervention protects cognition by enhancing glucose metabolism and inhibiting abnormal phosphorylation of Tau protein in the AD model mice, and the AKT/GSK3β pathway might play an irreplaceable role in the regulation process.

Objective: This study aims to explore the association between life events and coping styles, and how resilience and self-esteem mediate the association.Methods: A cross-sectional study was conducted among 981 left-behind adolescents (LBAs) in five junior high schools in Hunan Province, China, from April 13 to April 20, 2020. We utilized self-designed sociodemographic questionnaire, Adolescent Self-Rating Life Events Checklist, Resilience Scale Chinese Adolescent, Rosenberg Self-Esteem Scale, and Simplified Coping Style Questionnaire to assess the mental health of LBAs. Statistic description, Pearson correlation analysis, and structural equation model were adopted to analyze the data.Results: Results revealed that life events could negatively predict resilience (β = −0.29, P &lt; 0.001) and self-esteem (β = −0.39, P &lt; 0.001) and positively predict LBAs' positive coping style (β = 0.28, P &lt; 0.001) and negative coping style (β = 0.21, P &lt; 0.001). Self-esteem could also positively predict the resilience of LBAs (β = 0.62, P &lt; 0.001); resilience could negatively predict the negative coping style (β = −0.21, P &lt; 0.001) and positively predict the positive coping style (β = 0.79, P &lt; 0.001). Life events not only have direct effects on negative coping style (β = 0.21) and positive coping style (β = 0.28) but also have indirect effects on coping styles by affecting resilience (β = −0.29) and self-esteem (β = −0.39). The total effect of life events on coping styles was 0.32, where 34.37% was mediated by resilience and self-esteem.Conclusion: We proved that resilience and self-esteem mediated most of the effects of life events on coping styles. The findings had important implications for interventions to promote mental health of LBAs, particularly the enhancement of resilience and self-esteem.
