Key Points

TGF-β receptor 3 (TGFBR3) staining identifies a novel type of membranous nephropathy (MN).

TGFBR3-associated MN is enriched in patients with membranous lupus nephritis with similar characteristics as exostosin 1/2- and neural cell adhesion molecule 1–associated MN.

Identification of TGFBR3-associated MN should alert the clinician to evaluate for underlying autoimmune disease.

Background

Membranous lupus nephritis (MLN) comprises 10%–15% of lupus nephritis and increases morbidity and mortality of patients with SLE through complications of nephrotic syndrome and chronic kidney failure. Identification of the target antigens in MLN may enable noninvasive monitoring of disease activity, inform treatment decisions, and aid in prognostication, as is now possible for idiopathic MN caused by antibodies against the phospholipase A2 receptor. Here, we show evidence for type III TGF-β receptor (TGFBR3) as a novel biomarker expressed in a subset of patients with MLN.

Methods

Mass spectrometry was used for protein discovery through enrichment of glomerular proteins by laser capture microdissection and through elution of immune complexes within MLN biopsy specimens. Colocalization with IgG within glomerular immune deposits from patients and disease controls was evaluated by confocal microscopy. Immunostaining of consecutive case series was used to determine the overall frequency in MN and MLN.

Results

TGFBR3 was found to be enriched in glomeruli and coimmunoprecipitated with IgG within a subset of MLN biopsy specimens by mass spectrometry. Staining of consecutive MN cases without clinical evidence of SLE did not show TGFBR3 expression (zero of 104), but showed a 6% prevalence in MLN (11 of 199 cases). TGFBR3 colocalized with IgG along the glomerular basement membranes in TGFBR3-associated MN, but not in controls.

Conclusions

Positive staining for TGFBR3 within glomerular immune deposits represents a distinct form of MN, substantially enriched in MLN. A diagnosis of TGFBR3-associated MN can alert the clinician to search for an underlying autoimmune disease.
HyP-ABC: A Novel Automated Hyper-Parameter Tuning Algorithm Using Evolutionary Optimization
Authors: Zahedi Leila , Mohammadi Farid Ghareh , Amini M. Hadi
Published: June 2021

Machine learning techniques lend themselves as promising decision-making and analytic tools in a wide range of applications. Different ML algorithms have various hyper-parameters. In order to tailor an ML model towards a specific application, a large number of hyper-parameters should be tuned. Tuning the hyper-parameters directly affects the performance (accuracy and run-time). However, for large-scale search spaces, efficiently exploring the ample number of combinations of hyper-parameters is computationally challenging. Existing automated hyper-parameter tuning techniques suffer from high time complexity. In this paper, we propose HyP-ABC, an automatic innovative hybrid hyper-parameter optimization algorithm using the modified artificial bee colony approach, to measure the classification accuracy of three ML algorithms, namely random forest, extreme gradient boosting, and support vector machine. Compared to the state-of-the-art techniques, HyP-ABC is more efficient and has a limited number of parameters to be tuned, making it worthwhile for real-world hyper-parameter optimization problems. We further compare our proposed HyP-ABC algorithm with state-of-the-art techniques. In order to ensure the robustness of the proposed method, the algorithm takes a wide range of feasible hyper-parameter values, and is tested using a real-world educational dataset.
Damped Oscillations – A smartphone approach
Authors: Santamaría Marciano , Cruz de Gracia Evgeni , Dorneles Lucio
Published: June 2021

The study of the influence of geometric factors on an oscillating pendulum under various damping conditions is reported. Different cross-section areas perpendicular to the motion of the pendulum mass were studied. A smartphone was used as a pendulum and at the same time as a data recorder. Results show that the smartphone is an effective and reliable tool to be used when performing educational activities, and at the same time it presents students with a variety of ways for learning new content and physical concepts. It offers the opportunity to carry out experiments in the classroom, in the laboratory, or at home. In this way, the increment in the cross-section area slightly increases the damping coefficient, and rapidly decreases the oscillation amplitude as time passes. Additionally, the time necessary to decrease the amplitude by half is inversely proportional to the cross-section area of the pendulum. As expected, no significant variation in the period nor the angular frequency were found, due to the air-pendulum drag properties and to the slow pendulum speed.
Proper Definitions and Demonstration of Dirichlet Conditions

Published: June 2021

Fourier theory is the backbone of the area of Signal Processing (SP) and Communication Engineering. However, Fourier series (FS) or Fourier transform (FT) do not exist for some signals that fail to fulfill a predefined set of Dirichlet conditions (DCs). We note a subtle gap in the explanation of these conditions as available in the popular signal processing literature. They lack a certain degree of explanation essential for the proper understanding of the same. For example,

the original second Dirichlet condition is the requirement of bounded variations over one time period for the convergence of Fourier Series, where there can be at most infinite but countable number of maxima and minima, and at most infinite but countable number of discontinuities of finite magnitude. However, a large body of the literature replaces this statement with the requirements of finite number of maxima and minima over one time period, and finite number of discontinuities. The latter incorrectly disqualifies some signals from having valid FS representation. Similar problem holds in the description of DCs for the Fourier transform. Likewise, while it is easy to relate the first DC with the finite value of FS or FT coefficients, it is hard to relate the second and third DCs as specified in the signal processing literature with the Fourier representation as to how the failure to satisfy these conditions disqualifies those signals from having valid FS or FT representation.

Technological Disruptions, Youth Unemployment and Vocational Education Challenges in South Asia: A Short Report
Authors: Sudan Falendra Kumar
Published: June 2021

The main objectives of the study have been to analyze the situation of youth unemployment and employment in South Asia, challenges of skills gaps and job opportunities for youth in the context of technological changes, and draw policy implications to address youth employment challenges by reorienting the technical and vocational education and training (TVET) to leverage youth employment potential in changing demographic-economic-technological dynamics of South Asia. The study has drawn the secondary data from the two major databases of the International Labour Organization and the World Bank. Data triangulation method has been used to select the relevant data and the short-listed data has been analyzed through simple descriptive statistics and deductive content analysis to evaluate the data more comprehensively and scientifically. Theoretical triangulation method has been used to support the conclusions drawn from the findings and to lower the threat of wrong interpretation of research outcomes by a deeper and broader analysis. In the South Asian region, youth unemployment rate (YUR) has been estimated at 18.8% in 2020, which is projected to increase to 18.9% in 2021. High youth unemployment levels in South Asia have been due to a lack of appropriate skills through the TVET than the lack of jobs. In South Asian countries, skills for work have been largely provided at secondary and tertiary levels through TVET programs besides non-formal training programs in public and private institutions, including employers, but still, the skills mismatches are huge in the context of new technological changes and innovations. Therefore, robust policy actions are needed to address the skills gaps and meet the youth employment challenges by reorienting TVET programs to ensure that the skills taught in TVET are demanded and valued in the labor market.

Published: June 2021

Amplification of the MCL-1 gene induces MCL-1 overexpression, which is an important marker for drug resistance in several malignancies through evasion of apoptosis. We analysed 39 lung adenocarcinomas (ADCs), 38 lung squamous cell carcinomas (SCCs), two large cell lung carcinomas (LCCs) and cell lines. A duplex ratio test TaqMan qPCR approach was performed for MCL-1 copy number change analysis and we demonstrated amplification of MCL-1 in H1395 cell line and copy number gain (isochromosome) in H2342 cell line. Immunohistochemistry (IHC) and in situ hybridization (ISH) were performed for protein and mRNA analysis respectively. MCL-1 amplification was detected in 13% and 2.5% of SCCs and ADCs respectively. MCL-1-amplified tumours demonstrated high expression of MCL-1 mRNA. Copy number gain was detected in 2.5 % of ADC but not SCC.

Authors: Wang Limin , Womiloju Aisha Adebola , Höppener Christiane , Schubert Ulrich Sigmar , Hoeppener Stephanie
Published: June 2021

The stability of surface-enhanced Raman spectroscopy (SERS) substrates in different organic solvents and different buffer solutions was investigated. SERS substrates were fabricated by a microwave-assisted synthesis approach and the morphological as well as chemical changes of the SERS substrates were studied. It was demonstrated that the SERS substrates treated with methanol, ethanol, or N,N-dimethylformamide (DMF) were comparable and showed overall good stability and did not show severe morphological changes or a strong decrease in their Raman activity. Toluene treatment resulted in a strong decrease in the Raman activity whereas dimethyl sulfoxide (DMSO) treatment completely preserved or even slightly improved the Raman enhancement capabilities. SERS substrates immersed into phosphate-buffered saline (PBS) solutions were observed to be rather instable in low and neutral pH buffer solutions. Other buffer systems showed less severe influences on the SERS activity of the substrates and a carbonate buffer at pH 10 was found to even improve SERS performance. This study represents a guideline on the stability of microwave-fabricated SERS substrates or other SERS substrates consisting of non-stabilized silver nanoparticles for the application of different organic solvents and buffer solutions.

Experimental Study on the Effect of Triangular Plate Barrier Height on Flow Velocity Distribution in Open Channels
Authors: Hwa Lhiung Phung
Published: June 2021

Open and closed channel flow flows are distinct, the flow in the channels will constantly change. The flow will also be altered if the water level or flow velocity changes. It was found that employing the Pitot Tube Portable yielded findings identical to those calculated by other methods. A water transfer system is made up of natural or artificial structures via which water is moved from one site to another. The carrier building may be open or closed, depending on whether you want to utilize it as a shipping or receiving location. An open channel with a relatively narrow opening at the top is known as an open conduit. The speed data collection technique is carried out vertically, with a review point as illustrated above. The velocity of the flow was measured using a Pitot Tube Portable Automatic tool. The results are entered into the Froude number (fr) after each review point to determine the type of velocity flow at each Review point. The normal flow velocity distribution pattern emerges at the measurement sites of 450 cm, 500 cm, and 550 cm.

The chest stab injury is a clear sign that the injured person himself/herself or somebody else tried to take the injured person’s life. In these cases, forensic professionals often arrive at a criminal scene that has been previously altered for some reason, usually with the intention of helping when facilitating the urgent patient care or with sinful intent when disguising the act. Based on the data recorded in the report, the crime scene investigators should pay close attention to the act-related changes of the crime scene and provide reasonable explanations. When examining the crime scene, it always has been started off with the presupposition of the criminal act, looking for evidence of it, or grups of evidence against it. In case of a doubt between suicide and criminal acts, it is a professional failure to make the classification of the case dependent on the future outcome of the expert report, since the progress of time can even defeat the success of the investigation. In my two-part paper – starting with the theoretical background that is followed by the descriptive analysis of the cases – I intend to present aspects related to this initial analytical-evaluative work, in order to give awareness to the work of criminal investigators beside the undeniably necessary but easy-to-wear routine; and for the other actors in the judiciary, my intention is to shed light on the responsibilities of those who apply the law at the crime scene.
Biztonság mindenhol mindenkor

It is a generally believed and popular opinion among criminal experts who ap proach the issue superficially, that the impact of crime prevention work is undetectable, as it cannot be measured what does not happen. In particular, if the act of crime, becoming a victim or becoming a perpetrator is prevented, then the authorities have nothing to deal with it, no criminal data is generated from it, and it is not added to the criminal records. In this approach, the performance of crime prevention professionals cannot be measured. At most, it can only be measured how satisfied the target groups were with all the programs that the professionals had designed and implemented. Surveys of the effectiveness of crime prevention carried out in the recent years have pointed out those professional activities and methods that produced positive changes. Such a survey – given the high demand for human and financial resources – is rarely carried out. It is a necessity and a must to measure how crime prevention tendencies develop where the crime prevention activities are regular, systematic and adequate to the target groups. However, this would require a much larger research apparatus. The study presents the impact assessment of the crime prevention project ‘Safety anywhere and anytime’ of the Nógrád County Police Headquarters between 1 February and 31 October 2020. Based on the answers to twenty questions asked in the questionnaire, the opinion of the respondents about the series of 31 crime prevention events focusing on 11 program elements is revealed. The police wanted to participate in increasing common security of the ten catching-up settlements in the county with the colorful programs. This time the selected participants were Bárna, Buják, Diósjenő, Érsekvadkert, Kazár, Nagybárkány, Nógrádszakál, Rimóc, Szécsény and Varsány. The methods were varied: from a campaign event to trainings, and were designed to activate participants from children to the elderly. The results of the questionnaire clearly show positive reception, and it is encouraging news for the crime prevention professionals in Nógrád county. But maybe not only for them. Others can learn from them how to invent and implement a complex and therefore effective set of prevention programs. The final event of the project was also unusual. Due to the coronavirus situation, the summary event was planned to be carried out by applying the Police Café method, but it could not have been held with a personal presence, only virtually. In this way, the first online Police Café was also able to debut, where the results of the questionnaire survey were available to those who were interested.

The two determinants of transport are safety and speed. Both characteristics are essential for transport processes to be able to meet the demands of society. However, the two aspects have opposite effects, increasing speed could result decreasing road safety, while increasing safety would require speed reduction. Thus, for transport, especially for road transport it is an optimum search process. This process is influenced by many factors, from the average safety level of each vehicle to the state of the infrastructure. From the point of view of countries with a more developed transport culture, the number of road deaths per 1,000 people in Hungary is high. At the same time, there are societies from which Hungarian transport morale and road safety are high. As we can see the real safety of a transport system that is considered safe by the society also depends on the internal expectations of it. Increasing the road safety levels is a fundamental task, which requires the exploration of the actual problems. In this paper we examine the question of the role of the Hungarian high speed road infrastructure from the traffic safety’s point of view.

This time we give an insight into the topics of the international law enforcement literature, which are the current issues of law enforcement administration, protection of public order and public safety, and law enforcement. Among these is the methodology of action defined as a police monopoly on violence, which the Anglo-Saxon concept interprets as the nationalization of violence. A lot of attention falls to one of the most sensitive stages of law enforcement, the investigation of suspects, and in particular the procedural and psychological aspects of interrogations. Another area worth noting is the the forgery of travel documents, the concealment of identity, which not only makes it more difficult to combat illegal migration, but is often an instrument of serious crimes such as human trafficking, criminal organization or terrorism. We are dealing with the consequences of the rise of digital data, which on the one hand makes it easier to establish identity and, on the other hand, raises barriers to data protection. We can learn about application plans for artificial intelligence that can provide a promising perspective on predictive law enforcement tactics focused on crime prevention. A recurring theme is the comparison of military and police culture, the observation of the convergence of two inherently different threat response strategies. One of the targets of police intelligence is the uncovering of prostitution, especially with regard to trap situation created by undercover investigators, which need to be revised both in terms of constitutionality and violation of the principles of fair trial. No less exciting is to examine how the methodology of effective and non-violent policing could be further enriched so that good solutions can also be included in police training.

We present an iterative method for solving the convex constraint nonlinear equation problem. The method incorporates the projection strategy by Solodov and Svaiter with the hybrid Liu-Storey and Conjugate descent method by Yang et al. for solving the unconstrained optimization problem. The proposed method does not require the Jacobian information, nor does it require to store any matrix at each iteration. Thus, it has the potential to solve large-scale non-smooth problems. Under some standard assumptions, the convergence analysis of the method is established. Finally, to show the applicability of the proposed method, the proposed method is used to solve the \begin{document}$ \ell_1 $\end{document}-norm regularized problems to restore blurred and noisy images. The numerical experiment indicates that our result is a significant improvement compared with the related methods for solving the convex constraint nonlinear equation problem.

Our study aimed to evaluate the effect of trace element pollution in the polychaete Perinereis cultrifera (Grube, 1840) from two Tunisian coasts (the port of Rades, S1; and the Punic port of Carthage, S2). To this end, we used an approach based on proximate composition, biomarker responses and trace element bioaccumulation. Our results showed a decreasing order of metals concentrations (Zn>Cu>Cd>Pb) in P. cultrifera from S1 and S2. The accumulation of Cd, Cu and Zn was significantly higher in S1 than in S2, especially in summer. Lipid, protein and glycogen content also changed significantly between S1 and S2 in relation to trace metal accumulation and environmental conditions. The results revealed a higher level of thiobarbituric acid in P. cultrifera from S1 than from S2. In addition, the enzymatic and non-enzymatic antioxidant defence system (catalase, glutathione-S-transferase, superoxide dismutase, glutathione and metallothionein) was enhanced and acetylcholinesterase activities decreased in P. cultrifera in S1 in comparison with S2. A principal component analysis showed that P. cultrifera from S1 exhibited a clear disruption of oxidative stress responses and trace element bioaccumulation among seasons. Overall, these findings revealed the sensitivity of those organisms to environmental conditions.

This study analyses growth rates of bluefin tuna young-of-the-year in the Mediterranean. Potential differences in growth rates were examined between years (2013 and 2016) and regions (eastern, central and western Mediterranean). A total of 134 specimens were aged by analysing otolith microstructure. Fish sizes ranged between 14.7 and 57 cm fork length, and estimated ages varied between 45 and 192 days. The annual growth models explained more than 90% of growth variability. The observed differences in the growth rates between 2013 (3.2 mm d-1) and 2016 (2.7 mm d-1) were not significant, whereas the daily growth rate was significantly faster in the eastern region (4.01 mm d-1) than in the western (2.52 mm d-1) and central (2.75 mm d-1) regions. Larval hatching windows were consistent with the known spawning periods but lasted longer than previously reported in the central and eastern regions. In the central region the hatching period showed two peaks in mid-June and mid-July, consistent with previous studies pointing to two distinct spawning pulses. These pulses might be due to the existence of different bluefin tuna contingents spawning at different times, the Mediterranean residents and the Atlantic migrants, but further research is needed to support this hypothesis.
Une École qui crée de l’Autre
Authors: Mabilon-Bonfils Béatrice , Martin Virginie
Published: June 2021

Dans notre modèle politique, dont l’école a été l’instrument cardinal, l’Autre doit devenir le Même. L’école républicaine a été construite pour faire du Commun sur un mode assimilationniste. La présence désormais pensée comme durable des cultures minorées questionne notre mode citoyen et donc l’école. L’article historico-théorique se propose d’analyser un processus social de retournement : une école pensée pour faire du Commun (certes, un Commun produit de rapports sociaux) se transforme en une école qui crée de l’Autre. Il sera nourri d’illustrations empiriques.
La Marseillaise à l’École... ou pas ! Enseigner la France face à l’ethnicisation
Authors: Durpaire François
Published: June 2021

L’article 2 de la loi d’orientation du 23 avril 2005 rappelait qu’« outre la transmission des connaissances, la Nation fixe comme mission première à l’école de faire partager aux élèves les valeurs de la République. » Le code de l’éducation rappelle que l’éducation civique « comporte obligatoirement l’apprentissage de l’hymne national et de son histoire. » Qu’en est-il concrètement de l’enseignement de la Marseillaise, en comparaison par exemple avec les États-Unis où s’enseigne le Pledge of Allegiance ? Que dit cet enseignement ou non de l’hymne national du rapport de l’école à la transmission d’une « citoyenneté d’adhésion » qui était l’une de ses missions originelles ? Au-delà, enseigner la nation est-elle une des solutions envisagées pour construire du commun dans une école où différentes identités coexistent.
Les appartenances ethnoculturelles en contexte scolaire à Maurice : auto-identification des futurs enseignants, perception de la diversité des élèves et conception d’une citoyenneté commune
Authors: Cauchie Dimitri
Published: June 2021

Cet article présente une partie des résultats d’une enquête menée auprès des futurs enseignants mauriciens du cycle primaire durant notre recherche doctorale. Après une brève synthèse de la littérature relative à la diversité des identités ethnoculturelles à Maurice, nous présentons les données qui nous ont permis d’étudier la manière dont les sujets interrogés s’auto-identifiaient aux plans ethnique et culturel, envisageaient de prendre en compte la diversité de leur public scolaire dans leurs pratiques professionnelles, et concevaient une identité mauricienne commune. Ces résultats montrent une complexité identitaire dynamique et évolutive chez ces futurs enseignants. Si la multiplicité des appartenances communautaires dans lesquelles les Mauriciens peuvent se reconnaître n’est pas niée, il n’entre en revanche pas dans leurs intentions pédagogiques de prendre en considération les singularités culturelles de leurs futurs élèves. L’exclusion du facteur ethnoculturel de leurs activités professionnelles leur paraît être la voie juste de l’égalité scolaire, et le développement d’une identité commune est envisagé dans la perspective d’une « mauricianité » citoyenne ne se référant pas aux appartenances religieuses.

Introduction

Venovenous extracorporeal membrane oxygenation has been recommended as an effective rescue therapy for select critically ill patients with COVID-19. This case report describes a first experience caring for a patient with COVID-19 who received venovenous extracorporeal membrane oxygenation and expands the literature by discussing relevant nursing management and operational considerations.

Clinical Findings

A 46-year-old man presented to a hospital emergency department with pleuritic chest pain, dyspnea, anorexia, and chills. The patient was intubated for pneumonia-associated acute respiratory distress syndrome.

Diagnosis

A nasopharyngeal swab specimen was positive for SARS-CoV-2, and chest radiography confirmed a diagnosis of COVID-19 with acute respiratory distress syndrome.

Interventions

After no improvement with mechanical ventilation and prone positioning, the patient began receiving venovenous extracorporeal membrane oxygenation and was transferred to an extracorporeal membrane oxygenation center. Frontline critical care nurses played a vital role in coordinating patient care activities, monitoring changes in the patient’s condition, and detecting complications early.

Outcomes

The patient was decannulated on day 15 and extubated on day 17. The patient was successfully discharged home on hospital day 24.

Conclusion

Caring for a patient with COVID-19 receiving venovenous extracorporeal membrane oxygenation posed unprecedented challenges that required deviations from standards of care to optimize infection control measures and staff safety while providing quality care. This case report may inform, prepare, and guide other critical care nurses who will be caring for similar patients during this pandemic.

Published: June 2021

Classic Hodgkin lymphomas are neoplasms originating from lymphoid tissue. Primary extranodal classic Hodgkin lymphoma (PE-cHL) of the lung is rare. A 37-year-old Caucasian male was referred to our hospital for recurrent episodes of hemoptysis, cough and bronchitis. A CT scan showed a massive left upper lung consolidation, which was positive at the PET scan. After several inconclusive tests and no benefit from medical therapies, the patient underwent a left upper lobectomy; pathology report showed a classical type Hodgkin lymphoma with no lymph-nodes involvement. Four cycles of adjuvant chemotherapy were administered with no toxicity. At the last follow up 14 months after surgery, the patient is alive and free from disease. Primary extranodal classical Hodgkin lymphoma of the lung is a rare entity, but it should be considered as a differential diagnosis in young patients with pulmonary consolidation even without systemic symptoms.
Extensively drug-resistant Salmonella typhi causing rib osteomyelitis
Authors: Iqbal Sara , Thobani Humza , Fatimi Saulat
Published: June 2021

Rationale:

Salmonella (S.) typhi is a rare cause of osteomyelitis in immunocompetent adults. Extensive drug resistance (XDR) may lead to more complicated cases of S. typhi osteomyelitis.

Patient concern:

A 55-year-old female presented with a persistent low-grade fever and a swelling on her lower left chest with a sinus discharging purulent fluid for the past 8 months. Her symptoms had been unresponsive to previous anti-microbial therapy.

Diagnosis:

Rib osteomyelitis caused by XDR S. typhi.

Interventions:

Surgical wound debridement, left 7th-9th rib resection and intravenous IV meropenem were done.

Outcome:

Fever resolved and left-sided swelling resected without recurrence.

Lessons:

The prevalence of XDR S. typhi is growing in South Asia and should be considered as the differential diagnosis of chronic osteomyelitis.
