Purinergic signaling during rat embryonic development

Adenosine 5'-triphosphate (ATP) has been shown to be an important extracellular signaling molecule that mediates various physiological activities via the P2 (P2X and P2Y) receptors. However, information on the expression patterns of the P2 receptors during mammalian embryogenesis is limited. We therefore examined the expression patterns of different P2 receptor subtypes in rat embryos. In the hindbrain neural tube, the P2X3 receptor was transiently expressed at embryonic day E11 in the cranial motor neurons and the outgrowing axons. ATP significantly inhibited neurite outgrowth from neural tube explants. P2X3 receptors were also prominently expressed in sensory ganglia at this early stage and were coexpressed with P2X2 receptors in El6.5 embryos. Other P2X receptor subtypes were observed in different brain regions such as subventricular zones, the site of postnatal neurogenesis. In addition, the P2Y receptor expression was detected in the somites and subsequently in the developing skeletal muscle but was downregulated as development proceeded. While the P2Y1 receptor was no longer expressed in the adult skeletal muscle, the expression of P2Y2 receptor was present, although restricted in the satellite cells and the P2Y4 receptor showed reduced expression in adult skeletal muscle. Likewise, the expression of the P2Y receptors was initially expressed throughout the myocardium (El2) but was gradually restricted to the trabeculated myocardium (El4-18). Studies on Ca2+ influx showed that particular P2 receptor subtypes of P2X2, P2X4, P2Y1, P2Y2, P2Y4 and P2Y6 receptors responded to nucleotides in E14 cardiomyocytes. P2X7 receptor expression was detected in developing pancreatic islet cells and later coexpressed with glucagon in ? -cells. In addition, transient expression of the P2X7 receptor in insulin-expressing cells was observed in the embryonic, but not in adult, islet cells. Together, the results indicated that widespread and dynamic expression of P2 receptors was found in the three-germ layer-derived embryonic tissues, particularly in some transient embryonic structures during development, which suggested they may be important in embryonic organogenesis.
A nationwide assessment of perceptions of research-intense academic careers among predoctoral MD and MD-PhD trainees

Abstract Introduction: While previous studies have described career outcomes of physician-scientist trainees after graduation, trainee perceptions of research-intensive career pathways remain unclear. This study sought to identify the perceived interests, factors, and challenges associated with academic and research careers among predoctoral MD trainees, MD trainees with research-intense (>50%) career intentions (MD-RI), and MD-PhD trainees. Methods: A 70-question survey was administered to 16,418 trainees at 32 academic medical centers from September 2012 to December 2014. MD vs. MD-RI (>50% research intentions) vs. MD-PhD trainee responses were compared by chi-square tests. Multivariate logistic regression analyses were performed to identify variables associated with academic and research career intentions. Results: There were 4433 respondents (27% response rate), including 2625 MD (64%), 653 MD-RI (15%), and 856 MD-PhD (21%) trainees. MD-PhDs were most interested in pursuing academia (85.8%), followed by MD-RIs (57.3%) and MDs (31.2%). Translational research was the primary career intention for MD-PhD trainees (42.9%). Clinical duties were the primary career intention for MD-RIs (51.9%) and MDs (84.2%). While 39.8% of MD-PhD respondents identified opportunities for research as the most important career selection factor, only 12.9% of MD-RI and 0.5% of MD respondents shared this perspective. Interest in basic research, translational research, clinical research, education, and the ability to identify a mentor were each independently associated with academic career intentions by multivariate regression. Conclusions: Predoctoral MD, MD-RI, and MD-PhD trainees are unique cohorts with different perceptions and interests toward academic and research careers. Understanding these differences may help to guide efforts to mentor the next generation of physician-scientists.
A legitimate sphere of influence: Understanding France’s turn to multilateralism in Africa

ABSTRACT Scholars argue that the 1991 Gulf War, when the United States worked hard to secure approval from the United Nations (UN), set a precedent for legitimate military intervention that other states, especially other liberal democracies, subsequently felt compelled to follow. France, however, continued to intervene unilaterally in its traditional African sphere of influence for several years, without seeking approval from the UN or regional bodies. Even after France drew widespread opprobrium for its support of a murderous regime in Rwanda, French leaders deployed thousands of combat troops unilaterally on various missions. This article relies on original interviews with French policymakers as well as on primary documents to make the case that the 2002–04 Côte d’Ivoire intervention finally steered French Africa policy towards greater multilateralism. It drove home the danger that unilateral interventions could fuel anti-French sentiment among African audiences, undermining France’s regional influence. Ultimately, therefore, concerns about African acceptance more than broader international pressure led France to fully embrace new norms of legitimate intervention.
Occupational therapists’ views on core competencies that graduates need to work in the field of neurology in a South African context

Background. The burden of neurologically related conditions in South Africa (SA) necessitates that undergraduate occupational therapy education and training provide students with core competencies to deliver comprehensive, effective client-centred interventions. Given developments in the practice of neurology and changes in policy, funding and infrastructure, it is essential that training remains relevant and responsive to the needs of individuals and their context. Occupational therapists should be in touch with the local context and its challenges and consider the practicalities of the suggested interventions. Objectives. To explore occupational therapists’ perspectives on the knowledge, skills and attitudes that graduates need to work in the field of neurology. Methods. An explorative qualitative study consisting of semi-structured interviews was conducted with 10 occupational therapists in Western Cape Province, SA. Data were analysed using inductive analysis. Results. Four themes emerged from the findings, including foundational knowledge and skills, intra- and interpersonal attitudes, suggestions to consider when revising a neurology curriculum and resource constraints. Conclusions. This study highlighted that, in addition to neurology-specific skills, graduates also require core generic knowledge, skills and attitudes that address the evolving needs of society. These competencies are further necessary to allow graduates to work within the constraints of the health and educational systems.
Reducing Exchange Rate Risks in International Trade: A Hybrid Forecasting Approach of CEEMDAN and Multilayer LSTM

In international trade, it is common practice for multinational companies to use financial market instruments, such as financial derivatives and foreign currency debt, to hedge exchange rate risks. Making accurate predictions and decisions on the direction and magnitude of exchange rate movements is a more direct way to reduce exchange rate risks. However, the traditional time series model has many limitations in forecasting exchange rate, which is nonlinear and nonstationary. In this paper, we propose a new hybrid model of complete ensemble empirical mode decomposition (CEEMDAN) based multilayer long short-term memory (MLSTM) networks. It overcomes the shortcomings of the classic methods. CEEMDAN not only solves the mode mixing problem of empirical mode decomposition (EMD), but also solves the residue noise problem which is included in the reconstructed data of ensemble empirical mode decomposition (EEMD) with less computation cost. MLSTM can learning more complex dependences from exchange rate data than the classic model of time series. A lot of experiments have been conducted to measure the performance of the proposed approach among the exchange rates of British pound, the Australian dollar, and the US dollar. In order to get an objective evaluation, we compared the proposed method with several standard approaches or other hybrid models. The experimental results show that the CEEMDAN-based MLSTM (CEEMDAN–MLSTM) goes on better than some state-of-the-art models in terms of several evaluations.
Using Smart Routing for Secure and Dependable NoC-Based MPSoCs

The Internet-of-Things (IoT) boosted the building of computational systems that share computation, communication and storage resources for uncountable types of applications. MultiProcessor System-on-Chip (MPSoC) is a fundamental component of such systems offering large parallelism degree in an ocean of processors and memories connected through one or more Network-on-Chips (NoCs). Therefore, a massive quantity of sensitive information of several applications can share computation and communication resources of the MPSoCs demanding security mechanisms and policies. Besides, the advances of CMOS technologies increases the quantity of static and dynamic faults, requiring a dependable and resilient target architecture, which can be partially fulfilled by an effective and efficient NoC design. This work addresses fault tolerance and security at NoC level with SDR, a routing algorithm that includes the concept of security zones in the MPSoC while providing support for dependable routing avoiding faulty links. The proposed routing algorithm prioritizes communication paths deemed secure in 2D mesh NoCs with deadlock freedom. Experimental results employing realistic workload scenarios based on the NASA Numeric Aerodynamic Simulation (NAS) Parallel Benchmark (NPB) and a fault model for 65nm and 22nm CMOS fabrication technologies demonstrates the scalability, security, and dependability of SDR.
Substitution of fish meal by Jatropha curcas kernel meal: effects on growth performance and body composition of white leg shrimp (Litopenaeus vannamei).

Jatropha curcas (L.) is a multipurpose and drought-resistant tree, widespread throughout the tropics and subtropics. Its seeds are rich in oil and protein (contains 600–660 g kg−1 crude protein similar to fish meal). It is being promoted as a biofuel plant. Jatropha kernel meal obtained after oil extraction is an excellent source of protein. However, presence of toxic and antinutritional constituents restricts its use in fish and shrimp feed. An 8-week experiment was conducted to evaluate the nutritional quality of the detoxified Jatropha kernel meal (DJKM) in white leg shrimp (Litopenaeus vannamei). Shrimp (60) with an initial average body weight of 4.46 ± 0.64 g were randomly distributed into three treatments with four replicates and fed isonitrogenous and isoenergetic diets (crude protein 350 g kg−1, crude lipid 90 g kg−1): Control (fish meal-based protein), JC25 and JC50 (25% and 50% of fish meal protein replaced by DJKM). Higher (P 0.05) feed conversion ratio was observed in DJKM-fed groups, while protein efficiency ratio exhibited an opposite trend. Protein, ash and gross energy content of the whole shrimp body were higher (P < 0.05) in DJKM-fed groups compared to Control group. Moisture and lipid content of the whole shrimp body did not differ significantly among the three groups. Cholesterol level in plasma was highest (P < 0.05) in the Control group, followed by JC25 and JC50 groups; all being significantly different. In conclusion, DJKM is a promising fish meal replacer in shrimp diets.
Broadband and high gain multilayer multiresonator elliptical microstrip antenna

In this study, a low cost, broadband and high gain multilayer multiresonator microstrip antenna (MSA) is designed. It consists of one metallic fed patch at the bottom layer and two circular patches (1B2 T) are printed on the bottom side of the top FR4 substrate layer, which is air suspended. Two configurations with the bottom patch of circular and elliptical shapes are compared. The elliptical 1B2 T MSA provides better bandwidth (BW), i.e. 53.4% with peak gain of 9.8 dBi. The antenna design parameters are selected to provide maximum BW with uniform gain. The elliptical 1B2 T MSA is further enclosed in a metallic cavity, which improves the BW, gain and front to back (F/B) ratio of the antenna. The elliptical 1B2 T MSA with cavity enclosure is fabricated and tested. Experimental results are in agreement with simulated ones. The elliptical 1B2 T MSA with cavity provides 55.7% BW with peak gain of 12.1 dBi and F/B of >18 dB. The proposed antenna can be used in GPS, 2G, 3G, 4G and Wi-Fi frequency bands applications.
Psychometric Testing of a Spiritual Well-being Scale for People with Cancer

Spiritual well-being is crucial to the health outcomes of people with cancer and is influenced by culture, religious perspectives, and the characteristics of particular societies. There was no Thai instrument that measured this important concept, consequently, the Spiritual Well-being Scale for People with Cancer was developed by researchers and its psychometric properties were tested in this study. This instrument contains 20 items and the content validity index was . 88. People with cancer aged 18 years and over, who had at least two experiences of treatment, and could communicate in the Thai language were selected to be study participants. The dimensions of spiritual well-being were identified using exploratory factor analysis (n = 190) and internal consistency testing. Four factors accounting for 58.35% of the total variance were: spiritual strengthening, spiritual suffering, spiritual uncertainty, and spiritual readiness. The confirmatory factor analysis was tested (n = 203), and the results indicated that the measurement model had a good fit with the data. The Cronbach’s alpha coefficient of the entire scale was . 76. The correlation coefficient was tested with the other three instruments, and the results were between . 58 and . 75 (p < .001). The instrument has an acceptable level of content, construct, and concurrent validity, as well as internal consistency reliability. Nurses and other healthcare profession can use this instrument to assess and evaluate intervention designs to improve the spiritual well-being of people with cancer. It is recommended that the scale be further tested with other groups of people with cancer in Thailand.
Business Risk Evaluation of Electricity Retail Company in China Using a Hybrid MCDM Method

Electricity retail marketization reform is in progress in China, and many electricity retail companies (ERC) have been founded. The comprehensive evaluation of business risk for ERC can help effectively manage business risk and reduce risk loss, which is vital for its healthy and sustainable development. In this paper, a new hybrid multi-criteria decision making (MCDM) method integrating the Bayesian best-worst method (BBWM) and improved matter-element extension model (IMEEM) is proposed for business risk evaluation for an ERC. The latest group MCDM method, namely the BBWM is employed to determine risk criteria weights, and the IMEEM is used to rank the business risk of ERC. The evaluation index system is built including three aspects of economic operation risk, marketable risk and political risk. The business risk of ERC in China is evaluated by using the proposed MCDM method, and the result shows the current business risk belongs to ‘High’ grade and closer to ‘Very High’ grade more. The proposed MCDM method for business risk evaluation of ERC is effective and practical, which can provide references for risk management and sustainable development of ERC.
Multi-site evaluation of stable radiomic features for more accurate evaluation of pathologic downstaging on MRI after chemoradiation for rectal cancers

Tumor downstaging after neoadjuvant chemoradiation (CRT) in rectal cancer patients is typically assessed via Magnetic Resonance Imaging (MRI) in order to determine follow-up surgical interventions, but is associated with marked inter-reader variability and limited performance. While radiomic features have shown promise for evaluating chemoradiation response and tumor stage in rectal cancers, there is a need to determine how reproducible these features are across different MRI scanners and acquisitions. In this study, we evaluated radiomic feature reproducibility in terms of feature instability within a uniquely curated true healthy" rectum cohort in order to construct a stability-informed radiomic classifier for differentiating poorly from markedly down-staged rectal tumors after chemoradiation in a multi-site setting. We utilized a cohort of 156 patients, with (a) 74 MRIs visualizing the healthy rectum, (b) 52 post-CRT MRI scans in the discovery cohort, and (c) 30 post-CRT MRI scans in a second-site validation cohort; the latter 2 being from rectal cancer patients. 764 radiomic features were extracted from within the entire rectal wall on each MRI scan. Feature instability was used to quantify how reproducible each radiomic feature was between the discovery cohort and the healthy rectum cohort, using locations along the rectum that were spatially distinct from the treated tumor region. From the resulting stability-informed" feature set, the most relevant features were identified to distinguish pathologic tumor stage groups in the discovery cohort via a QDA classifier with cross-validation to ensure robustness. The top 4 radiomic features were then evaluated in hold-out fashion on scans from the validation cohort. We found that utilizing a stability-informed radiomic model (which comprised features that were reproducible in 100% of all comparisons) was significantly more accurate in identifying pathological tumor stage regression in both discovery (AUC=0:66 ± 0:09) and validation (AUC=0.73) cohorts, compared to a basic radiomic model that used all extracted features (AUC=0:60 ± 0:07 in discovery, AUC=0.62 in validation). Evaluating feature instability with respect to healthy rectal tissue may thus enhance the performance of radiomic models in characterizing pathologic downstaging in rectal cancers, via MRI.
Equipment-Level Locating of Low Frequency Oscillating Source in Power System With DFIG Integration Based on Dynamic Energy Flow

In view of the complex correlation between Doubly Fed Induction Generator (DFIG) internal components and control links which makes it difficult to locate the oscillating source in the equipment level, a DFIG equipment-level oscillating source locating method based on dynamic energy flow is proposed. Firstly, the energy correlation topology network of DFIG internal components and control links is constructed. On this basis, the analytical expressions of dynamic energy flows of DFIG internal components and control links are derived. And then, through Partial Directional Coherence (PDC) analysis, the values of causality between dynamic energy flows of DFIG internal components and control links are calculated, and the diagram of DFIG internal oscillation transmission causality is depicted. Thus according to the distribution pattern of causality values in the causality diagram, the oscillation transmission route is identified and the oscillating source is located. Finally, simulation tests in Real Time Digital Simulator (RTDS) of IEEE 10-machine 39-bus system verify that, the proposed method can quantitatively describe the intensity of interaction between dynamic energy flows of DFIG internal components and accurately identify the oscillation transmission route and the oscillating source in the equipment level. The proposed method can accurately track the original control link/physical component that causes the system to oscillate. Therefore, this paper will facilitate research on DFIG parameter tuning and oscillation suppression measures for low-frequency oscillation in power system.
An Analysis of Communities’ Attitudes Toward Wildlife and Implications for Wildlife Sustainability

Negative human–wildlife interactions do not only have adverse effects on rural livelihoods but also lead to negative attitudes toward wildlife conservation. This research uses primary data collected from 221 randomly selected households in the Okavango Delta to analyze their perceptions on poaching and community involvement in anti-poaching activities. The results reveal that the majority of the respondents acknowledge the existence of poaching within their communities. Close to 50% of the respondents noted that they poach for subsistence purposes. There is a generally low participation rate in anti-poaching efforts in the study area. The study concludes that the negative attitudes of communities toward wildlife and wildlife conservation threaten wildlife sustainability in the Okavango Delta. There is a need to strike an intricate balance between wildlife conservation and improving communities’ welfare and tolerance to wildlife through designing effective institutions that are aligned to local realities.
Structural and Electrical Properties of Ca2+ Doped LaFeO3: The Effect of A-site Cation Size Mismatch

In this study, nanosized La1-xCaxFeO3 (0.00≤x≤0.40) compounds prepared via sol-gel method followed by heat treatment at 1100oC for 24 hours are studied. Crystal structure, microstructure, surface morphology and temperature-dependent resistivity of the samples are investigated. TEM investigation reveals nanoparticles with an average size of 35nm produced from the sol-gel process. The crystal structure of the compounds belongs to an orthorhombically distorted perovskite structure with Pbnm space group. Lattice distortion and cation size mismatch increase with an increase in Ca and particle and grain growth are suppressed by Ca doping. Electrical conduction is explained via thermally activated hopping of small polarons. Unit cell volume, charge ordering temperature, and activation energy for small polarons decrease linearly with an increase in cation size mismatch. Room temperature resistivity decreases with Ca doping and gets its minimum value for 30% Ca at which the orthorhombic distortion is maximum.
