Targeting the alternative oxidase (AOX) for human health and food security, a pharmaceutical and agrochemical target or a rescue mechanism?
Authors: Szibor Marten , Schenkl Christina , Barsottini Mario R. O. , Young Luke , Moore Anthony L.
Published: June 2022

Some of the most threatening human diseases are due to a blockage of the mitochondrial electron transport chain (ETC). In a variety of plants, fungi, and prokaryotes, there is a naturally evolved mechanism for such threats to viability, namely a bypassing of the blocked portion of the ETC by alternative enzymes of the respiratory chain. One such enzyme is the alternative oxidase (AOX). When AOX is expressed, it enables its host to survive life-threatening conditions or, as in parasites, to evade host defenses. In vertebrates, this mechanism has been lost during evolution. However, we and others have shown that transfer of AOX into the genome of the fruit fly and mouse results in a catalytically engaged AOX. This implies that not only is the AOX a promising target for combating human or agricultural pathogens but also a novel approach to elucidate disease mechanisms or, in several cases, potentially a therapeutic cure for human diseases. In this review, we highlight the varying functions of AOX in their natural hosts and upon xenotopic expression, and discuss the resulting need to develop species-specific AOX inhibitors.
Students' Reflections During Training Workshops on Communication and Information Exchange in Audiology Consultations: An Exploratory Qualitative Study
Authors: Watermeyer Jennifer , Kanji Amisha
Published: June 2022

Purpose:

This clinical focus article outlines various communication challenges and scenarios related to information giving encountered by a group of audiology students, as reflected on during a series of communication skills workshops.

Method:

We held two online training workshops during which students reflected on their clinical communication experiences and asked questions related to clinical scenarios. Third-year audiology students from a South African university participated in the workshops (17 in the first, 15 in the second). We analyzed these reflections using thematic analysis.

Results:

Students' reflections related to four themes: (a) balancing information giving, (b) managing shared decision making, (c) managing linguistic differences, and (d) relating bad news. The first theme was heavily prioritized in students' reflections. Providing students with time to practice skills introduced in the initial communication skills workshop enabled further reflection in the subsequent workshop. We discuss these themes using specific examples raised by students.

Conclusions:

Our findings suggest that students first need to master basic information giving skills before they can move on to more advanced skills such as managing shared decision making, linguistic differences, and relating bad news. This study confirms that reflective skills need to be developed with students in an explicit manner, rather than as part of a hidden curriculum. Our approach to providing communication training and encouraging reflection on clinical experiences offers a starting point for clinical educators to support students in developing these skills.
Applying project‐based learning in artificial intelligence and marine discipline: An evaluation study on a robotic sailboat platform
Authors: Lin Xiongwei , Liu Hengli , Sun Qinbo , Li Xiuhan , Qian Huihuan , Sun Zhenglong , Lam Tin Lun
Published: June 2022

Artificial intelligence is penetrating various fields. The demand for interdisciplinary talent is increasingly important, while interdisciplinary educational activities for high school students are lagging behind. Project‐based learning (PBL) in artificial intelligence (AI) and robotic education activities supported by a robotic sailboat platform, the sailboat test arena (STAr), has been shown to popularise AI and robotic knowledge in young students. In the implementation of the programme, PBL was provided for students, and gamification pedagogy was applied to increase participants' learning motivation and engagement. The results show that the proposed STAr‐based programme is capable of delivering the desired knowledge and skills to students at high school levels. The assessment results suggest that most students achieve learning outcomes on average. Students showed more interest in AI and marine disciplines and were willing to participate in more such educational programs. The findings fill the research gap that few existing education platforms have facilitated the teaching and learning of AI and marine disciplines for high school students.
The role of nonlocal response in second harmonic generation at metasurfaces with triangular metaatoms
Authors: Habibullah Yusuf B. , Ishihara Teruya
Published: June 2022

Metasurface consisting of square array of obtuse isosceles triangle metaatoms is found to exhibit much more efficient second harmonic generation (SHG) compared to that of split ring resonators and its heptagonal modification, experimentally as well as numerically. All of them are designed to lack inversion symmetry in horizontal direction but to have vertical symmetry, and to meet the double resonance condition for vertically-polarized fundamental and horizontally-polarized SHG waves. SHG efficiencies were estimated numerically for each structure by evaluating an overlap integral of second order nonlinear polarization and field distribution at the SHG wavelength. The large overlap integral for the triangle metasurface is ascribed to the nonlocal response at the SHG wavelength. Current induced at the center of the triangle near the obtuse angle by horizontally polarized light at SHG wavelength flows toward two corners of acute angles. As a result, polarization charges oscillate in time at the surfaces of two acute corners, which results in strong field oscillation away from the center where the electric field is applied to majority of free electrons. Experimentally observed wavelength dependence of SHG efficiencies for the three metasurfaces are reasonably reproduced by a numerical estimation.
Investigations on the source term of the detection of radionuclides in North of Europe in June 2020
Authors: Ingremeau Jean-Jacques , Saunier Olivier
Published: June 2022

During the second half of June 2020, small quantities of artificial radionuclides (60Co, 134Cs, 137Cs, 103Ru, 106Ru, 141Ce, 95Nb, 95Zr) have been detected in northern Europe (Finland, Sweden, Estonia), the source of the release being unknown. The measured values were close to detection limits and didn’t represent any health issue. This paper presents the investigations carried out at IRSN in order to identify the release origin. The most probable source location and the release magnitude estimation are briefly presented. This recent set of detection is also compared to previous similar ones. This paper mainly focuses on the investigations which have been performed in order to answer two main questions. First “from which type and part of a nuclear installation the release could come from?”. Although no certainty is achievable, the most probable source is found to be a spent primary ion exchange resin. The second question addressed was “how this radiological inventory could have been released into the atmosphere?”. But, mainly due to the lack of information, no satisfying answer has been found to that question and what really happened remains unknown.
Algebraic wavenumber identification method in presence of uncertainty
Authors: Li Xuefeng , Ichchou Mohamed , Droz Christophe , Zine Abdel-Malek , Bouhaddi Noureddine
Published: June 2022

This paper presents an algebraic wavenumber identification method to identify wavenumbers under stochastic conditions. Stochastic condition results from the introduction of small perturbation which is referred to the uncertainty of measurements points’ coordinates caused by the operation faults or problems with experimental errors. The proposed method is compared with two popular alternatives, namely: inhomogeneous wave correlation method and inverse convolution method which are both capable of extracting the bending wavenumbers of a meta-structure. A good performance is observed for the identification of complex wavenumbers in presence of uncertainty. In addition, the proposed method needs to solve a linear problem, reducing the computational cost compared to the inhomogeneous wave correlation method.

Published: June 2022

The modern paradigm of education requires a rethinking of the mission of universities and their role for social, economic and knowledge-intensive development of states. The main research is based on fundamental developments in pedagogy, philosophy of education, management of education and educational process, in particular on humanistic pedagogy, effective methodology of educational process, anthropological pedagogy, internationalization and globalization of higher education. Different forms of global cooperation viewed as a standard are vital for the overall thinking, environmental, economic and social dimension. Almost every developed country has extensive experience in building a system of higher education. The results of the analysis of this experience can contribute to the development and enrichment of the domestic education system, avoid the recurrence of mistakes and the opportunity to discover new approaches to solving a number of problems in this area. Universities should be able to go through a smooth, continuous process of change that ensures the effectiveness of the university’s research activities and provides resources for teaching and learning. This requires rethinking the idea of change from decision-making to perspective, which perceives change as a new reality and builds an institutional culture based on change.
Realization of human rights and freedoms when checking a crime report, taking into account digitalization
Authors: Budanova Lyudmila , Mikhailova Olga , Kazak Bronislav
Published: June 2022

The reforms of the domestic criminal procedure legislation carried out in recent years in Russia are primarily aimed at improving the effectiveness of the implementation of the rights and freedoms of persons involved in the sphere of criminal proceedings, the beginning of which, according to the criminal procedure law, is conditioned by the receipt of a crime report by the competent authorities and activities to verify it. However, the analysis of the effectiveness of pre-trial proceedings conducted by the internal affairs bodies refers only to crimes, the analysis of data on the number of registered crime reports and the number of refusals to initiate criminal proceedings is not published by the official data of the Ministry of Internal Affairs of Russia. At the same time, one of the fundamental indicators of the activity of the internal affairs bodies is the increase in the number of unsolved criminal cases, which indirectly indicates an unwillingness to initiate criminal proceedings until, during the verification of a crime report, a person subject to further involvement as a suspect is identified after the decision to initiate a criminal case is made.

Introduction: Microsoft Kinect V2® (Kinect) is a peripheral device of Xbox® and acquires information such as depth, posture, and skeleton definition. In this study, we investigated whether Kinect can be used for human gait analysis. Methods: Ten healthy volunteers walked 20 trials, and each walk was recorded by a Kinect and infrared- and marker-based-motion capture system. Pearson’s correlation and overall agreement with a method of meta-analysis of Pearson’s correlation coefficient were used to assess the reliability of each parameter, including gait velocity, gait cycle time, step length, hip and knee joint angle, ground contact time of foot, and max ankle velocity. Hip and knee angles in one gait cycle were calculated in Kinect and motion capture groups. Results: The coefficients of correlation for gait velocity (r = 0.92), step length (r = 0.81) were regarded as strong reliability. Gait cycle time (r = 0.65), minimum flexion angle of hip joint (r = 0.68) were regarded as moderate reliability. The maximum flexion angle of the hip joint (r = 0.43) and maximum flexion angle of the knee joint (r = 0.54) were regarded as fair reliability. Minimum flexion angle of knee joint (r = 0.23), ground contact time of foot (r = 0.23), and maximum ankle velocity (r = 0.22) were regarded as poor reliability. The method of meta-analysis revealed that participants with small hip and knee flexion angles tended to have poor correlations in maximum flexion angle of hip and knee joints. Similar trajectories of hip and knee angles were observed in Kinect and motion capture groups. Conclusions: Our results strongly suggest that Kinect could be a reliable device for evaluating gait parameters, including gait velocity, gait cycle time, step length, minimum flexion angle of the hip joint, and maximum flexion angle of the knee joint.

Published: June 2022

Objective This study aimed to determine whether a trial of labor after cesarean section (TOLAC) with a macrosomic neonate is associated with adverse outcomes.

Study Design A retrospective cohort study was conducted in a population motivated for TOLAC. Women attempting TOLAC with a neonatal birth weight >4,000 g were compared with women attempting TOLAC with neonatal birth weights between 3,500 and 4,000 g. The primary outcome was TOLAC success. Secondary outcomes included mode of delivery, uterine rupture, postpartum hemorrhage (PPH), shoulder dystocia, obstetric anal sphincter injury (OASI), Apgar's score <7 at 5 minutes, and umbilical artery pH <7.1. Data were analyzed using Fisher's exact test and Chi‐square test.

Results Overall, 375 women who underwent TOLAC with a neonate weighing >4,000 g comprised the study group. One thousand seven hundred and eighty-three women attempting TOLAC with a neonate weighing 3,500 to 4,000 g comprised the control group. There were no clinically significant differences between the groups for maternal age, gestational age, parity, and vaginal birth after cesarean (VBAC) rate. There were no significant differences in the rates of successful TOLAC (94 vs. 92.3%, p = 0.2, odds ratio [OR] = 0.8, 95% confidence interval [CI]: 0.5, 1.2), operative vaginal delivery (7.4 vs. 5.3%, p = 0.18, OR = 0.7, 95% CI: 0.4, 1.1), uterine rupture (0.4 vs. 0%, p = 0.6), PPH (3.2 vs. 2.3%, p = 0.36, OR = 1.4, 95% CI: 0.7, 2.7), OASI (0.8 vs. 0.2%, p = 0.1, OR = 3.6, 95% CI: 0.8, 1.6), Apgar's score <7 at 5 minutes (0 vs. 0.4%, p = 0.37), and umbilical artery pH <7.1 (0.5 vs. 0.7%, p = 1.0, OR = 0.73, 95% CI: 0.2, 3.2). Women with a neonate weighing >4,000 g had a significantly increased risk of shoulder dystocia (4 vs. 0.4%, p < 0.05, OR = 9.2 95% CI: 3.9, 22)

Conclusion Women attempting TOLAC with a macrosomic neonate are not at increased risk for failed TOLAC, operative vaginal delivery, uterine rupture, PPH, or OASI but are at risk of shoulder dystocia. This information may aid in prenatal counseling for women considering TOLAC with a macrosomic fetus.

The treatment of gender dysphoria consists of psychiatric evaluation, initiation of hormonal therapy, and the final step in an individual's transition, performing gender-affirming surgery. Construction of the neophallus is one of the most demanding tasks in genital affirming surgery of transgender men. The main objectives of phalloplasty are to achieve a cosmetically acceptable and functional phallus, with a neourethra that allows voiding in standing position, sufficient length and strength for possible penetrative intercourse, preserved tactile and orgasmic sensation, and acceptable donor site morbidity. The musculocutaneous latissimus dorsi flap has reliable and suitable anatomy (good size, volume, and length of neurovascular pedicle) to meet the esthetic and functional requirements of neophallus reconstruction. Despite many advantages, the main disadvantage of this flap is the lack of sensitivity. Although the radial free forearm flap technique is the most commonly performed procedure, musculus latissimus dorsi flap is an acceptable choice in gender-affirming surgery.

Introduction The nasopharynx and oropharynx are the main colonization sites of coronavirus. Therefore, patients with paranasal sinuses and pharyngeal problems (ear, nose, and throat [ENT] patients) predispose coronavirus infection.

Ear, nose, and throat patients with concomitant asymptomatic coronavirus infection may develop severe pneumonia following surgical procedures. As a result, presurgical screening for coronavirus infection is a substantial concern.

Objective We evaluated the usefulness of a spiral chest computed tomography (CT) scan in the diagnosis of asymptomatic coronavirus infection in the presurgical assessment of ENT patients

Methods In this study, candidates of paranasal sinus or pharyngeal surgery were evaluated for coronavirus infection. Patients with neither history of coronavirus disease 2019 (COVID-19) nor compatible symptoms and signs were screened for asymptomatic coronavirus infection. These patients composed two groups: the first group underwent a reverse transcription polymerase chain reaction (RT-PCR) test of nasopharyngeal sample and spiral chest CT scan, but for the second one, only the latter was performed.

Results In the first group, which consisted of 106 patients, 11 (10.4%) cases had positive RT-PCR test results, and 17 (16%) patients showed positive findings in favor of coronavirus infection in the spiral chest CT scan. In the second group, which consisted of 173 patients, 34 (19.7%) cases had positive chest CT scan results.

Conclusion The chest CT scan has a valuable role in the early diagnosis of asymptomatic coronavirus carriers in patients highly predisposed to infection, especially in low resource areas, where the RT-PCR test is unavailable.

Published: June 2022

Background Histoplasmosis is a rare cause of primary adrenal insufficiency. Adrenal involvement is commonly encountered with disseminated disease in immunocompromised individuals though some have been reported in immunocompetent patients. Primary adrenal histoplasmosis where adrenals are the only organs with demonstrable disease is uncommon.

Case Presentation A 33-year-old immunocompetent man presented with an adrenal crisis. Further evaluation of the underling etiology of primary adrenal insufficiency revealed bilateral adrenal enlargement that was confirmed to be histoplasmosis on adrenal biopsy.

Conclusion The case highlights the importance of considering histoplasmosis as an underlying cause of primary adrenal insufficiency in patients from high endemic areas.

Objetivo Describir el uso de los cuestionarios reportados por pacientes (patient-reported outcome measures, PROMs, en inglés) en cirugía de tobillo y pie en Chile.

Materiales y métodos Estudio descriptivo, transversal, en el que se diseñó y se aplicó una encuesta para conocer el uso de PROMs en Chile. Se invitó a participar a los traumatólogos cuya actividad principal fuese la cirugía de tobillo y pie.

Resultados En total, 73 de 110 traumatólogos contestaron la encuesta. El 75% de los encuestados ha utilizado PROMs al menos una vez, y el 50% los utiliza de manera regular. La finalidad con la que se utilizan es principalmente de investigación (83%), y su aplicación es realizada la mayoría de las veces por los médicos del equipo (94%). Se identificaron 15 cuestionarios distintos aplicados en nuestro medio, siendo los más utilizados la Escala Visual Análoga (EVA), la Escala de Tobillo y Retropié de la American Orthopaedic Foot and Ankle Society (AOFAS), el 36-item Short Form Health Survey (SF-36), y la Escala de Resultados de Tobillo y Pie (Ankle and Foot Outcome Score, FAOS, en inglés). Los encuestados que no han utilizado estos cuestionarios señalaron como principales limitantes la falta de información, de tiempo y de personal capacitado.

Conclusión El 75% de los traumatólogos dedicados a la cirugía de tobillo y pie encuestados ha utilizado PROMs en su práctica clínica. Existe una amplia variedad de cuestionarios aplicados, y el presente estudio constituye la primera aproximación de su aplicación en nuestro medio.

Atypical Posterior Reversible Encephalopathy Syndrome in Intraorbital Lymphoma after Tumor Biopsy: An Illustrative Case
Authors: Vongsfak Jirapong , Norasethada Thunya , Unsrisong Kittisak
Published: June 2022

Introduction A 63-year-old male presented with visual loss and left eye proptosis. Magnetic resonance imaging revealed a left orbital tumor, measuring 1.4 cm × 0.9 cm. The patient underwent left frontotemporal craniotomy to perform a biopsy of the tumor. During the postoperative period, the patient developed the first episode of a generalized tonic–clonic seizure.

Case Summary Computed tomography of the brain showed hypodensity of the bilateral basal ganglia and thalami with associated edematous white matter hypodensity of bilateral temporo-occipital lobes compatible with atypical posterior reversible encephalopathy syndrome (PRES). The patient received antiepileptic medication and was observed for clinical seizure. One week later, computed tomography of the brain showed the reversible process of PRES. The pathology report revealed diffuse large B cell lymphoma. Following pathological diagnosis, the patient received treatment with whole-brain radiotherapy.

Conclusion This is the first reported case of atypical PRES associated with orbital lymphoma following craniotomy for the purpose of tumor biopsy. Early detection as well as seizure and blood pressure control, is essential for the proper treatment of PRES.

Janus interpenetrating structure based on optimized water supply for solar-driven water evaporation

Published: June 2022

Realizing a balance between water supply and the evaporation of photothermal evaporators is a valuable means to enhance the solar–thermal evaporation rate, but practical obstacles remain. The interfacial mechanics of a Janus evaporator with an interpenetrating structure are proposed to achieve a dramatic improvement in the solar–thermal evaporation rate. The Janus evaporator is composed of a membrane material of Cu1.96S grown in situ on a foamed copper skeleton (CF@Cu1.96S) and a graphene oxide/sodium alginate aerogel (GA), through an interfacial freeze-drying shape technology. In this unique architecture, the superhydrophilic GA can be stretched into the hydrophobic CF@Cu1.96S interior to build an interpenetrating network architecture (CF@Cu1.96S/GA), thereby adjusting the Laplace pressure and constraining capillarity. Due to the optimized water supply of interfacial mechanics, the CF@Cu1.96S/GA evaporator achieves an evaporation rate of 1.79 kg m−2 h−1 under 1 sun irradiation and exhibits superior salt resistance. This provides a rationale for the reasonable design of the structure of the solar–thermal evaporators.

Published: June 2022

We report on the free charge carrier properties of a two-dimensional electron gas (2DEG) in an AlN/AlxGa1–xN high electron mobility transistor structure with a high aluminum content (x = 0.78). The 2DEG sheet density Ns=(7.3±0.7)×1012 cm−2, sheet mobility μs=(270±40) cm2/(Vs), sheet resistance Rs=(3200±500) Ω/◻, and effective mass meff=(0.63±0.04)m0 at low temperatures (T=5 K) are determined by terahertz (THz) optical Hall effect measurements. The experimental 2DEG mobility in the channel is found within the expected range, and the sheet carrier density is in good agreement with self-consistent Poisson–Schrödinger calculations. However, a significant increase in the effective mass of 2DEG electrons at low temperatures is found in comparison with the respective value in bulk Al0.78Ga22N (meff=0.334 m0). Possible mechanisms for the enhanced 2DEG effective mass parameter are discussed and quantified using self-consistent Poisson–Schrödinger calculations.
Partial event coincidence analysis for distinguishing direct and indirect coupling in functional network construction

Published: June 2022

Correctly identifying interaction patterns from multivariate time series presents an important step in functional network construction. In this context, the widespread use of bivariate statistical association measures often results in a false identification of links because strong similarity between two time series can also emerge without the presence of a direct interaction due to intermediate mediators or common drivers. In order to properly distinguish such direct and indirect links for the special case of event-like data, we present here a new generalization of event coincidence analysis to a partial version thereof, which is aimed at excluding possible transitive effects of indirect couplings. Using coupled chaotic systems and stochastic processes on two generic coupling topologies (star and chain configuration), we demonstrate that the proposed methodology allows for the correct identification of indirect interactions. Subsequently, we apply our partial event coincidence analysis to multi-channel EEG recordings to investigate possible differences in coordinated alpha band activity among macroscopic brain regions in resting states with eyes open (EO) and closed (EC) conditions. Specifically, we find that direct connections typically correspond to close spatial neighbors while indirect ones often reflect longer-distance connections mediated via other brain regions. In the EC state, connections in the frontal parts of the brain are enhanced as compared to the EO state, while the opposite applies to the posterior regions. In general, our approach leads to a significant reduction in the number of indirect connections and thereby contributes to a better understanding of the alpha band desynchronization phenomenon in the EO state.
A definition of the asymptotic phase for quantum nonlinear oscillators from the Koopman operator viewpoint
Authors: Kato Yuzuru , Nakao Hiroya
Published: June 2022

We propose a definition of the asymptotic phase for quantum nonlinear oscillators from the viewpoint of the Koopman operator theory. The asymptotic phase is a fundamental quantity for the analysis of classical limit-cycle oscillators, but it has not been defined explicitly for quantum nonlinear oscillators. In this study, we define the asymptotic phase for quantum oscillatory systems by using the eigenoperator of the backward Liouville operator associated with the fundamental oscillation frequency. By using the quantum van der Pol oscillator with a Kerr effect as an example, we illustrate that the proposed asymptotic phase appropriately yields isochronous phase values in both semiclassical and strong quantum regimes.
