Purpose: we reviewed that the mental fatigue is influenced by dopamine depletion, and we assume that increasing DA level can increase athletic stamina and promote athletic performance after prolong exercise. Methods: The search strategy was according to key words contain, Mental fatigue , Decision making , Dopamine, Stroboscope training through the Google scholar, PubMed, and Elsevier. Among the literatures, 100 papers include review and original articles were studied. Finally, we decided to select 49 papers based on similarity and recent studies so more than 50 percent of papers were excluded, because of they were out of date or irrelevant to key words. Results: Based on many studies, it was found dopamine has an essential role on athletic performance and his stamina. Conclusion: The stroboscope vision training in sports could enhance the dopaminergic neurons and associated visuo-motor skills

Forecasting the prices of hogs has always been a popular field of research. Such information has played an essential role in decision-making for farmers, consumers, corporations, and governments. It is hard to predict hog prices because too many factors can influence them. Some of the factors are easy to quantify, but some are not. Capturing the characteristics behind the price data is also tricky considering their non-linear and non-stationary nature. To address these difficulties, we propose Heterogeneous Graph-enhanced LSTM (HGLTSM), which is a method that predicts weekly hog price. In this paper, we first extract the historical prices of necessary agricultural products in recent years. Then, we utilize discussions from the online professional community to build heterogeneous graphs. These graphs have rich information of both discussions and the engaged users. Finally, we construct HGLSTM to make the prediction. The experimental results demonstrate that forum discussions are beneficial to hog price prediction. Moreover, our method exhibits a better performance than existing methods.

Dopaminergic Pathway

Taste memory involves storing information through plasticity changes in the neural network of taste, including the insular cortex (IC) and ventral tegmental area (VTA), a critical provider of dopamine. Although a VTA-IC dopaminergic pathway has been demonstrated, its role to consolidate taste recognition memory remains poorly understood. We found that photostimulation of dopaminergic neurons in the VTA or VTA-IC dopaminergic terminals of TH-Cre mice increases the salience to facilitate consolidation of a novel taste stimulus regardless of its hedonic value, without altering their taste palatability. Importantly, the inhibition of the D1-like receptor into the IC impairs the salience to facilitate consolidation of an aversive taste recognition memory. Finally, our results showed that VTA photostimulation improves the salience to facilitate consolidation of a conditioned taste aversion memory through the D1-like receptor into the IC. It is concluded that the dopamine activity from the VTA into IC is required to increase the salience to facilitate consolidation of a taste recognition memory. Notably, the D1-like receptor activity into the IC is required to consolidate both innate and learned aversive taste memories but not appetitive taste memory.

Participation Mechanisms

This study identifies the impacts of different citizen satisfaction signals (positive/negative) on managers’ agreement to use various participation channels. Citizen satisfaction with public service quality plays an essential role in managers’ accountability expectations. Accordingly, it is crucial to examine how public managers use participation mechanisms, reacting to citizen satisfaction signals on public service quality. The results confirm a negativity bias: Managers are more reactive to citizens’ negative signals than a positive signal in their service quality evaluations. However, the negative signal’s effect does not reach the participation tools, where the degree of their decision-making is highly delegated to citizens.

IntroductionOpioid use disorder (OUD) is characterised by the fifth Edition of the Diagnostic and Statistics Manual as a problematic pattern of opioid use (eg, fentanyl, heroin, oxycodone) that leads to clinically significant impairment. OUD diagnoses have risen substantially over the last decade, and treatment services have struggled to meet the demand. Evidence suggests when patients with chronic illnesses are matched with their treatment preferences and engaged in shared decision-making (SDM), health outcomes may improve. However, it is not known whether SDM could impact outcomes in specific substance use disorders such as OUD.Methods and analysisA scoping review will be conducted according to Arksey and O’Malley’s framework and by recommendations from Levacet al. The search strategy was developed to retrieve relevant publications from database inception and June 2017. MEDLINE, EMBASE, PsycINFO, Cochrane Database for Controlled Trials, Cochrane Database for Systematic Reviews and reference lists of relevant articles and Google Scholar will be searched. Included studies must be composed of adults with a diagnosis of OUD, and investigate SDM or its constituent components. Experimental, quasi-experimental, qualitative, case–control, cohort studies and cross-sectional surveys will be included. Articles will be screened for final eligibility according to title and abstract, and then by full text. Two independent reviewers will screen excluded articles at each stage. A consultation phase with expert clinicians and policy-makers will be added to set the scope of the work, refine research questions, review the search strategy and identify additional relevant literature. Results will summarise whether SDM impacts health and patient-centred outcomes in OUD.Ethics and disseminationScoping review methodology is considered secondary analysis and does not require ethics approval. The final review will be submitted to a peer-reviewed journal, disseminated at relevant academic conferences and will be shared with policy-makers, patients and clinicians.

Impairment of autophagy has been strongly implicated in the progressive loss of nigral dopaminergic neurons in Parkinson’s disease (PD). Transcription factor E3 (TFE3), an MiTF/TFE family transcription factor, has been identified as a master regulator of the genes that are associated with lysosomal biogenesis and autophagy. However, whether TFE3 is involved in parkinsonian neurodegeneration remains to be determined. In this study, we found decreased TFE3 expression in the nuclei of the dopaminergic neurons of postmortem human PD brains. Next, we demonstrated that TFE3 knockdown led to autophagy dysfunction and neurodegeneration of dopaminergic neurons in mice, implying that reduction of nuclear TFE3 may contribute to autophagy dysfunction-mediated cell death in PD. Further, we showed that enhancement of autophagy by TFE3 overexpression dramatically reversed autophagy downregulation and dopaminergic neurons loss in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) model of PD. Taken together, these findings demonstrate that TFE3 plays an essential role in maintaining autophagy and the survival of dopaminergic neurons, suggesting TFE3 activation may serve as a promising strategy for PD therapy.
