Published: August 2020

Urinary volatile compounds (VCs) have been recently assessed for disease diagnoses. They belong to very diverse chemical classes, and they are characterized by different volatilities, polarities and concentrations, complicating their analysis via a single analytical procedure. There remains a need for better, lower-cost methods for VC biomarker discovery. Thus, there is a strong need for alternative methods, enabling the detection of a broader range of VCs. Therefore, the main aim of this study was to optimize a simple and reliable liquid–liquid extraction (LLE) procedure for the analysis of VCs in urine using gas chromatography-mass spectrometry (GC-MS), in order to obtain the maximum number of responses. Extraction parameters such as pH, type of solvent and ionic strength were optimized. Moreover, the same extracts were analyzed using Proton Nuclear Magnetic Resonance Spectroscopy (1H-NMR), to evaluate the applicability of a single urine extraction for multiplatform purposes. After the evaluation of experimental conditions, an LLE protocol using 2 mL of urine in the presence of 2 mL of 1 M sulfuric acid and sodium sulphate extracted with dichloromethane was found to be optimal. The optimized method was validated with the external standards and was found to be precise and linear, and allowed for detection of >400 peaks in a single run present in at least 50% of six samples—considerably more than the number of peaks detected by solid-phase microextracton fiber pre-concentration-GC-MS (328 ± 6 vs. 234 ± 4). 1H-NMR spectroscopy of the polar and non-polar extracts extended the range to >40 more (mainly low volatility compounds) metabolites (non-destructively), the majority of which were different from GC-MS. The more peaks detectable, the greater the opportunity of assessing a fingerprint of several compounds to aid biomarker discovery. In summary, we have successfully demonstrated the potential of LLE as a cheap and simple alternative for the analysis of VCs in urine, and for the first time the applicability of a single urine solvent extraction procedure for detecting a wide range of analytes using both GC-MS and 1H-NMR analysis to enhance putative biomarker detection. The proposed method will simplify the transport between laboratories and storage of samples, as compared to intact urine samples.

Cytotoxic and cytostatic chemotherapeutics act by attacking rapidly dividing tumor cells, predominantly affecting malignant tissue and to a certain degree preserving healthy cells. Nonetheless, severe side effects are caused as quickly proliferating healthy cells such as hematopoietic precursors and mucous membranes are impaired as well. This limits the administered dose and eventually allows tumor cells to escape treatment. In order to increase intratumoral drug concentration and simultaneously reduce systemic side effects, nanoparticles have come into focus as drug carriers. The functionalization of superparamagnetic iron oxide nanoparticles (SPIONs) with chemotherapeutics such as mitoxantrone (MTO) enables targeted drug transport by using magnetic forces. Here, we investigate SPIONs consisting of individual iron oxide cores of 10 nm in diameter and a total hydrodynamic diameter of 53 ± 0.8 nm as a transporting system for MTO. Comparing the killing efficacy in monolayer cell culture and multicellular tumor spheroids of HT-29 cells, we show that spheroids tolerate considerably higher doses of nanoparticle-loaded MTO. Therefore, dose predictions from conventional monolayer cell cultures are often misleading for in vivo applications. This was true for both soluble and nanoparticle-bound MTO. Using flow chambers mimicking in vivo blood flow, we furthermore demonstrate that SPIONs can magnetically accumulate MTO. We conclude that SPIONs can function as an effective delivery platform to increase local drug concentrations, thereby potentially overcoming chemotherapy resistance of cells.
MicroRNAs: Biogenesis, Functions and Potential Biomarkers for Early Screening, Prognosis and Therapeutic Molecular Monitoring of Nasopharyngeal Carcinoma
Authors: Lao Thuan Duc , Le Thuy Ai Huyen
Published: August 2020

According to reports published, the aberrant expression of microRNAs (miRNAs), a class of 19–25 nucleotide-long small non-coding RNAs, is responsible for human cancers, including nasopharyngeal cancer (NPC). The dysregulation of miRNAs that act either as a tumor suppressor or oncogene, leading to a wide range of NPC pathogenesis pathways, includes the proliferation, invasion, migration as well as the metastasis of NPC cells. This article reviews and highlights recent advances in the studies of miRNAs in NPC, with a specific demonstration of the functions of miRNA, especially circulating miRNAs, in the pathway of NPC pathogenesis. Additionally, the possible use of miRNAs as early screening and prognostic biomarkers and for therapeutic molecular monitoring has been extensively studied.

Published: August 2020

There is a growing interest in a fluidized bed particle receiver that directly irradiates sunlight to particles in the fluidized bed as a solar thermal collector for heating. Thermal performance of directly-irradiated fluidized bed gas heater is strongly affected by the physical properties of the particles. The effect of SiC particle size on heat transfer characteristics in the solar fluidized bed gas heater (50 mm-ID × 100 mm high) has been determined. The outlet gas temperatures showed a maximum value with increasing gas velocity due to the particles motion by bubble behavior in the bed, and the maximum values were found at 3.6 times of Umf for fine SiC and less than 2.0 times of Umf for coarse SiC. Heat absorption from the receiver increased with increasing gas velocity, showing with maximum 18 W for the fine SiC and 23 W for the coarse SiC at 4.5 times of Umf. The thermal efficiency of the receiver increased with increasing gas velocity, but was affected by the content of finer particles. The maximum thermal efficiency of the receiver was 14% for fine SiC and 20% for coarse SiC within the experimental range, but showing higher for the fine SiC at the same gas velocity. A design consideration was proposed to improve the thermal efficiency of the system.

Published: August 2020

Error-related potentials (ErrPs) have provided technical support for the brain-computer interface. However, different visual stimulations may affect the ErrPs, and furthermore, affect the error recognition based on ErrPs. Therefore, the study aimed to investigate how people respond to different visual stimulations (static and dynamic) and find the best time window for different stimulation. Nineteen participants were recruited in the ErrPs-based tasks with static and dynamic visual stimulations. Five ErrPs were statistically compared, and the classification accuracies were obtained through linear discriminant analysis (LDA) with nine different time windows. The results showed that the P3, N6, and P8 with correctness were significantly different from those with error in both stimulations, while N1 only existed in static. The differences between dynamic and static errors existed in N1 and P2. The highest accuracy was obtained in the time window related to N1, P3, N6, and P8 for the static condition, and in the time window related to P3, N6, and P8 for the dynamic. In conclusion, the early components of ErrPs may be affected by stimulation modes, and the late components are more sensitive to errors. The error recognition with static stimulation requires information from the entire epoch, while the late windows should be focused more within the dynamic case.
Enhancing Border Gateway Protocol Security Using Public Blockchain

Published: August 2020

Communication on the Internet consisting of a massive number of Autonomous Systems (AS) depends on routing based on Border Gateway Protocol (BGP). Routers generally trust the veracity of information in BGP updates from their neighbors, as with many other routing protocols. However, this trust leaves the whole system vulnerable to multiple attacks, such as BGP hijacking. Several solutions have been proposed to increase the security of BGP routing protocol, most based on centralized Public Key Infrastructure, but their adoption has been relatively slow. Additionally, these solutions are open to attack on this centralized system. Decentralized alternatives utilizing blockchain to validate BGP updates have recently been proposed. The distributed nature of blockchain and its trustless environment increase the overall system security and conform to the distributed character of the BGP. All of the techniques based on blockchain concentrate on inspecting incoming BGP updates only. In this paper, we improve on these by modifying an existing architecture for the management of network devices. The original architecture adopted a private blockchain implementation of HyperLedger. On the other hand, we use the public blockchain Ethereum, more specifically the Ropsten testing environment. Our solution provides a module design for the management of AS border routers. It enables verification of the prefixes even before any router sends BGP updates announcing them. Thus, we eliminate fraudulent BGP origin announcements from the AS deploying our solution. Furthermore, blockchain provides storage options for configurations of edge routers and keeps the irrefutable history of all changes. We can analyze router settings history to detect whether the router advertised incorrect information, when and for how long.

Published: August 2020

As an important paradigm of spontaneous brain-computer interfaces (BCIs), motor imagery (MI) has been widely used in the fields of neurological rehabilitation and robot control. Recently, researchers have proposed various methods for feature extraction and classification based on MI signals. The decoding model based on deep neural networks (DNNs) has attracted significant attention in the field of MI signal processing. Due to the strict requirements for subjects and experimental environments, it is difficult to collect large-scale and high-quality electroencephalogram (EEG) data. However, the performance of a deep learning model depends directly on the size of the datasets. Therefore, the decoding of MI-EEG signals based on a DNN has proven highly challenging in practice. Based on this, we investigated the performance of different data augmentation (DA) methods for the classification of MI data using a DNN. First, we transformed the time series signals into spectrogram images using a short-time Fourier transform (STFT). Then, we evaluated and compared the performance of different DA methods for this spectrogram data. Next, we developed a convolutional neural network (CNN) to classify the MI signals and compared the classification performance of after DA. The Fréchet inception distance (FID) was used to evaluate the quality of the generated data (GD) and the classification accuracy, and mean kappa values were used to explore the best CNN-DA method. In addition, analysis of variance (ANOVA) and paired t-tests were used to assess the significance of the results. The results showed that the deep convolutional generative adversarial network (DCGAN) provided better augmentation performance than traditional DA methods: geometric transformation (GT), autoencoder (AE), and variational autoencoder (VAE) (p < 0.01). Public datasets of the BCI competition IV (datasets 1 and 2b) were used to verify the classification performance. Improvements in the classification accuracies of 17% and 21% (p < 0.01) were observed after DA for the two datasets. In addition, the hybrid network CNN-DCGAN outperformed the other classification methods, with average kappa values of 0.564 and 0.677 for the two datasets.

Published: August 2020

Face recognition is a valuable forensic tool for criminal investigators since it certainly helps in identifying individuals in scenarios of criminal activity like fugitives or child sexual abuse. It is, however, a very challenging task as it must be able to handle low-quality images of real world settings and fulfill real time requirements. Deep learning approaches for face detection have proven to be very successful but they require large computation power and processing time. In this work, we evaluate the speed–accuracy tradeoff of three popular deep-learning-based face detectors on the WIDER Face and UFDD data sets in several CPUs and GPUs. We also develop a regression model capable to estimate the performance, both in terms of processing time and accuracy. We expect this to become a very useful tool for the end user in forensic laboratories in order to estimate the performance for different face detection options. Experimental results showed that the best speed–accuracy tradeoff is achieved with images resized to 50% of the original size in GPUs and images resized to 25% of the original size in CPUs. Moreover, performance can be estimated using multiple linear regression models with a Mean Absolute Error (MAE) of 0.113, which is very promising for the forensic field.
Adaptive Fine Distortion Correction Method for Stereo Images of Skin Acquired with a Mobile Phone
Authors: Moon Cho-I , Lee Onseok
Published: August 2020

With the development of the mobile phone, we can acquire high-resolution images of the skin to observe its detailed features using a mobile camera. We acquire stereo images using a mobile camera to enable a three-dimensional (3D) analysis of the skin surface. However, geometric changes in the observed skin structure caused by the lens distortion of the mobile phone result in a low accuracy of the 3D information extracted through stereo matching. Therefore, our study proposes a Distortion Correction Matrix (DCM) to correct the fine distortion of close-up mobile images, pixel by pixel. We verified the correction performance by analyzing the results of correspondence point matching in the stereo image corrected using the DCM. We also confirmed the correction results of the image taken at the five different working distances and derived a linear regression model for the relationship between the angle of the image and the distortion ratio. The proposed DCM considers the distortion degree, which appears to be different in the left and right regions of the image. Finally, we performed a fine distortion correction, which is difficult to check with the naked eye. The results of this study can enable the accurate and precise 3D analysis of the skin surface using corrected mobile images.

Authors: Reynaud Lucile , Bouchet-Spinelli Aurélie , Raillon Camille , Buhot Arnaud
Published: August 2020

In the 90s, the development of a novel single molecule technique based on nanopore sensing emerged. Preliminary improvements were based on the molecular or biological engineering of protein nanopores along with the use of nanotechnologies developed in the context of microelectronics. Since the last decade, the convergence between those two worlds has allowed for biomimetic approaches. In this respect, the combination of nanopores with aptamers, single-stranded oligonucleotides specifically selected towards molecular or cellular targets from an in vitro method, gained a lot of interest with potential applications for the single molecule detection and recognition in various domains like health, environment or security. The recent developments performed by combining nanopores and aptamers are highlighted in this review and some perspectives are drawn.

Authors: Li ChunHei , Parker Jody , Reeves Nicola , Cornish Julie
Published: August 2020

Introduction. Knowledge of fecal incontinence (FI) in medical professionals is poor. Undergraduate education is limited despite its relevance to many specialties. Our aim was to review undergraduate curriculum requirements for FI across the UK and evaluate the impact of a teaching tool on medical student knowledge. Methods. Governing bodies and medical school curricula were identified and searched for FI knowledge requirements. A questionnaire was developed to assess undergraduate exposure to FI teaching. This information was consolidated with a discussion group involving medical students and used to develop an e-learning module. Intervention was performed by trialing the module in a group of medical students and evaluated with feedback. Results. There is a considerable absence of undergraduate learning requirements for FI. Only 19% of medical students had received teaching on the subject despite there being a demand for more coverage (43%). A group discussion guided the development of an e-learning module. Introduction of this significantly improved medical students understanding in all aspects of diagnosis and management of FI. Conclusions. There is a shortfall in the undergraduate curriculum requirements for this common and debilitating problem. An e-learning module can enhance knowledge and understanding in medical students to improve patient care and management.
Primary medical care continuity and patient mortality: a systematic review
Authors: Baker Richard , Freeman George K , Haggerty Jeannie L , Bankart M John , Nockels Keith H
Published: August 2020

Background

A 2018 review into continuity of care with doctors in primary and secondary care concluded that mortality rates are lower with higher continuity of care.

Aim

This association was studied further to elucidate its strength and how causative mechanisms may work, specifically in the field of primary medical care.

Design and setting

Systematic review of studies published in English or French from database and source inception to July 2019.

Method

Original empirical quantitative studies of any design were included, from MEDLINE, Embase, PsycINFO, OpenGrey, and the library catalogue of the New York Academy of Medicine for unpublished studies. Selected studies included patients who were seen wholly or mostly in primary care settings, and quantifiable measures of continuity and mortality.

Results

Thirteen quantitative studies were identified that included either cross-sectional or retrospective cohorts with variable periods of follow-up. Twelve of these measured the effect on all-cause mortality; a statistically significant protective effect of greater care continuity was found in nine, absent in two, and in one effects ranged from increased to decreased mortality depending on the continuity measure. The remaining study found a protective association for coronary heart disease mortality. Improved clinical responsibility, physician knowledge, and patient trust were suggested as causative mechanisms, although these were not investigated.

Conclusion

This review adds reduced mortality to the demonstrated benefits of there being better continuity in primary care for patients. Some patients may benefit more than others. Further studies should seek to elucidate mechanisms and those patients who are likely to benefit most. Despite mounting evidence of its broad benefit to patients, relationship continuity in primary care is in decline — decisive action is required from policymakers and practitioners to counter this.
GPs’ practice and attitudes to initiating isotretinoin for acne vulgaris in Ireland: a cross-sectional questionnaire survey in primary care
Authors: Carmody Kevin , Rouse Martin , Nolan Dermot , Quinlan Diarmuid
Published: August 2020

Background

Isotretinoin is prescribed in secondary care for severe acne vulgaris. Anecdotal reports suggest that GPs in Ireland currently initiate isotretinoin.

Aim

To ascertain the prevalence and management of isotretinoin in Irish general practice and to describe GPs’ attitudes about the use of isotretinoin in Ireland.

Design and setting

A cross-sectional questionnaire survey of GPs in Ireland between October 2018 and February 2019.

Method

Two short questionnaires were developed: one for GPs who prescribe isotretinoin and one for GPs who do not prescribe isotretinoin. Questionnaires were distributed via email and online via GP Forum to GPs in Ireland.

Results

Of a total 298 GPs who completed the questionnaire, 52 (17%) initiated isotretinoin. Older GPs (aged 35 years) and male GPs were more likely to prescribe isotretinoin. GPs cited prolonged dermatology waiting lists (n = 34, 65%) and a special interest in dermatology (n = 31, 60%) as two key drivers to initiating isotretinoin. However, this study found evidence of suboptimal blood monitoring, pregnancy testing, and contraceptive advice. Most GPs (n = 246, 83%) did not initiate isotretinoin and identified multiple barriers: medicolegal concerns (n = 150, 61%), being unaware that GPs may initiate isotretinoin (n = 135, 55%), and being unfamiliar with managing isotretinoin (n = 102, 41%). Important enablers to initiating isotretinoin cited by GPs include Irish College of General Practitioners guidelines (n = 118, 48%) and dermatologist support (n = 119, 48%). Two-thirds of the GPs questioned (n = 164, 67%) expressed an interest in initiating isotretinoin and most (n = 223, 91%) agreed that GPs can safely manage isotretinoin.

Conclusion

Few GPs in Ireland currently initiate treatment of acne with isotretinoin, and there is suboptimal adherence to recommended monitoring. Barriers to and enablers for GPs initiating isotretinoin were identified. Most GPs expressed an interest in initiating isotretinoin.

A Educação Ambiental frente à sociedade de consumo e a necessidade de sustentabilidade
Authors: Vieira Laurentino Bernardes
Published: August 2020

O crescimento demográfico mundial que vem ocorrendo principalmente a partir do século XX, a industrialização, a urbanização, a produção e o consumo de massa têm colocado o conceito de desenvolvimento sustentável em xeque. Uma análise na literatura que aborda tal temática mostra que esse conceito foi forjado sob a perspectiva do capitalismo, o qual demanda sempre angariar a produção, o consumo e o lucro, sempre em nome do desenvolvimento, mas isso implica, muitas vezes, explorar os recursos naturais do planeta além de sua capacidade de reposição, além de provocar impactos ambientais que afetam negativamente a vida de muitas pessoas. Há necessidade de mudanças na produção e no consumo, e a Educação Ambiental é um instrumento imprescindível nesse processo de construção de sociedades realmente sustentáveis.

este ensaio teórico pretende oferecer aos educadores ambientais uma perspectiva epistêmica relacionada à educação, por meio de um novo pensar a partir da Pandemia criada pela COVID-19. Esse pensar fundamenta-se nos conceitos da complexidade e transdisciplinaridade, que são capazes de – por meio de projetos criativos ecoformadores, de uma nova racionalidade aberta, do pensar livre, multidimensional e multiocular – reorganizar ideias de forma ecossistêmica, oferecer criticidade e intelectualidade sistêmica, oportunizando a compreensão da diversidade e gerando bem-estar. Tais capacidades ampliadas no pensar sistêmico advêm da mudança do paradigma vigente, que não pode mais seguir lógica cartesiana, mas precisa se regenerar e renascer em respeito e consciência ampliados.

Published: August 2020

Issues related to entrepreneurship in the agricultural sector in particular involving SMEs young agropreneurs are gaining attention in Malaysia. To date, the agricultural sector remains the third most important contributor to Malaysia's economic growth after the services and manufacturing sectors. Development and efforts to empower the agricultural sector are still lacking in the involvement of young people, especially those who are highly educated in boosting the country's economy and producing successful SMEs young agropreneurs need to be addressed immediately. So, it becomes a necessity to develop a profile of successful SMEs young agropreneur so that the landscape of the agricultural sector can be transformed from a sector pioneered by the elderly to young people with entrepreneurial mindsets, entrepreneurial skills, and entrepreneurial attitudes. Therefore, the objective of this study is to develop the profile of successful SME young agropreneurs in the North of Peninsular Malaysia. This study was conducted using quantitative methods by distributing questionnaire forms to SMEs young agropreneurs who are participants of the Young Agropreneur Program. A total of 289 data were analyzed using SPSS software version 23. The findings show that the majority of SMEs young agropreneurs succeed in higher education by graduating with a Diploma and Bachelor's Degree and are involved in agricultural production activities such as crops, livestock, and fisheries. The implications of this study are expected to change the perceptions and mentality of young people towards the agricultural sector and further able to attract the interest of young people, especially those who are highly educated to venture into the agricultural sector as a lucrative career.

Authors: Nascimento Renata Morais do , Marcellino Nelson Carvalho
Published: August 2020

Este artigo de revisão procura analisar algumas contribuições para os estudos do lazer a partir da “teoria do processo civilizador”, de Norbert Elias, consubstanciadas em A busca da excitação: desporto e lazer no processo civilizacional, de Elias e Eric Dunning. São destacados os seguintes pontos: crítica à tradicional análise do lazer como prática presa à dicotomia “lazer x trabalho”; entendimento do lazer como uma busca por excitação e prazer que, por conta do controle exercido sobre os impulsos das pessoas, não podem ser manifestados na vida cotidiana; distinção entre os conceitos de “tempo livre” e “lazer”. As contribuições são importantes para quem se propõe a estudar questões relacionadas ao lazer.

Authors: Das St. Wardah Hanafie , Syakir Muh. , Juliadi Juliadi
Published: August 2020

Sekolah umum seperti SMA Negeri 10 Enrekang membutuhkan pendidikan karakter dan Pendidikan Agama Islam (PAI) yang efektif dan masif. Kurikulum 2013 menegaskan PAI sebagai mata pelajaran inti dalam membentuk karakter peserta didik di sekolah. Peserta didik pada jenjang SMA berada pada masa adolesen yang secara kejiwaan masih labil. Masa ini peserta didik (muslim) membutuhkan PAI dalam mengawal perkembangan psikologisnya. Realitas di SMA Negeri 10 Enrekang, peserta didik kurang fokus belajar PAI disebabkan berbagai variabel yang mengitarinya. Di sisi lain, karakteristik PAI bersifat kompleks yakni doktrin, keyakinan, pengetahuan, pengamalan, dan akhlakul karimah. Berbagai persoalan yang lahir dalam pembelajaran PAI, baik dari aspek materi dalam kurikulum 2013, motivasi belajar peserta didik, kompetensi pendidik, dan aspek lainnya. Kurikulum 2013 dalam bidang PAI semestinya bersifat adaptif dan merangkum perkembangan psikis peserta didik dan relevan dengan realitas sosial. Pendidik PAI dituntut memiliki multi-kompetensi, yakni kompetensi pedagogik, profesional, kepribadian, sosial, religius, cybernetik, enterpreneurship, dan manajerial. Kompetensi pendidik PAI tersebut dinilai lebih berpeluang dapat meningkatkan motivasi belajar peserta didik. Kompetensi pendidik PAI dapat menguasai perangkat pembelajaran, prosedur, sistematika, desain media dan sumber belajar, setting strategi dan metode pembelajaran, desain evaluasi pembelajaran, dan manajemen kelas.
