Developments in Wireless Power Transfer Using Solar Energy
Authors: Dehra Himanshu
Published: March 2021

This chapter presents state-of-the-art and major developments in wireless power transfer using solar energy. The brief state-of-the-art is presented for solar photovoltaic technologies which can be combined with wireless power transfer (WPT) to interact with the ambient solar energy. The main purpose of the solar photovoltaic system is to distribute the collected electrical energy in various small-scale power applications wirelessly. These recent developments give technology based on how to transmit electrical power without any wires, with a small-scale by using solar energy. The power can also be transferred wirelessly through an inductive coupling as an antenna. With this wireless electricity we can charge and make wireless electricity as an input source to electronic equipment such as cellphone, MP3 Player etc. In harvesting energy, technologies of ambient solar radiation like solar photovoltaic, kinetic, thermal or electro-magnetic (EM) energy can be used to recharge the batteries. Radio frequency (RF) harvesting technologies are also popular as they are enormously available in the atmosphere. The energy converted to useful DC energy which can be used to charge electrical devices which need low power consumption. The chapter has also presented a parallel plate photovoltaic amplifier connected to a potentiometer as a Resistance-Capacitance (RC) circuit power amplifier. The effect of inductance and resulting power transfer has been theoretically determined in the RC amplifier circuit. The electrical and thermal properties and measurements from a parallel plate photovoltaic amplifier were collected to analyze the unbalanced power transfer and inductance in a nonlinear RC circuit amplifier using equivalent transfer functions. The concept of Wireless Information and Power Transfer using Electromagnetic and Radio Waves of Solar Energy Spectrum is also briefly outlined.
S’engager dans un monde complexe

Published: March 2021

In this article, I propose to question under what conditions an act of engagement can take place for causes that escape our immediate perception (in a phenomenological way), even though our hypermodern lifestyles are ambivalent: they allow us to open up to the world through information technology, but they also close us to our own subjective spheres. In the digital age, access to information is indeed becoming more and more personalized and dependent on algorithmic recommendation logics. The more we create cognitive bubbles, the more we make it difficult to access a common world, as well as to get morally involved in distant causes.
Incidence of Corrected QT Prolongation With Concomitant Methadone and Atypical Antipsychotics in Critically Ill Children
Authors: Hughes Kaitlin M. , Thorndyke Anne , Tillman Emma M.
Published: March 2021

OBJECTIVE

To evaluate the safety of the combination of methadone and an atypical antipsychotic in PICU patients.

METHODS

This was a retrospective observational cohort pilot study in a single-center PICU in an academic children's hospital. Children 1 month to 18 years of age were included if they received methadone, were then initiated on an atypical antipsychotic (i.e., quetiapine or risperidone), and had EKG monitoring before and after medication initiation.

RESULTS

Prolongation of the corrected QT (QTc) interval occurred in 5 of the 34 included patients when an atypical antipsychotic was added to methadone. Of the 5 patients who had a prolonged QTc interval, 4 (80%) were older than 12 years and had a median weight of 91.3 kg. There were statistical differences between age and weight when comparing patients who experienced QTc prolongation, but no differences in sex, ethnicity, electrolyte deficiencies, number of additional QTc-prolonging medications, and number of additional drug-drug interactions were identified. When comparing atypical antipsychotics, 9.5% of patients receiving risperidone had a prolonged QTc interval, versus 23% of patients receiving quetiapine (p = 0.04). The net change in QTc interval after initiation of methadone was 0.19 milliseconds (IQR: −3, 15), which increased after atypical antipsychotic initiation to 4 milliseconds (IQR: −16, 15).

CONCLUSIONS

Our pilot trial suggests there is no clinically significant difference in incidence of QTc prolongation with addition of atypical antipsychotics to methadone.
Combination Anti-IgE and Anti-IL5 Therapy in a Pediatric Patient With Severe Persistent Asthma
Authors: Fox Haley M. , Rotolo Shannon M.
Published: March 2021

Biologic agents, including anti-immunoglobulin E (omalizumab) and anti-interleukin 5 (mepolizumab), target different mediators involved in the inflammatory process and may work synergistically to decrease symptoms in patients with severe asthma. Here we describe a 12-year-old female on 2 biologic agents, omalizumab and mepolizumab, to control severe persistent asthma. Omalizumab was started years earlier with an initial response; however, her asthma again became uncontrolled and mepolizumab was added. Both biologics were administered concomitantly for over 6 months with marked improvement of asthma symptoms without significant side effects. A combination of biologic agents may be a potential therapy for pediatric patients with severe persistent asthma that remains uncontrolled on a single agent.

The paper summarises what industry business entities in Serbia need to do in order to be more numerous and more efficient. The paper consists of theoretical research that was realised in accordance with the techniques of the methodology of scientific research.
Harmony between economy and environment
Authors: Vukićević-Petković Milica , Šmigić-Miladinović Jasmina
Published: March 2021

Since the environment surpasses all the frames created by men, the basic aim of this paper is to point to how important the quality of the environment is, as well as to discuss whether the two, protection of the environment and economy endorsement, can function together. The economy which does not respect natural resources in an adequate way is irrational. That is why the importance of social awareness of the environment's sacrificing for the purpose of economic progress is underlined. It is not always sufficient to abandon everything to various interests, and thus secure the most favourable economic status, but it is also necessary to refocus people's economic functioning to the promotion of the environment. This paper analyses economy's essential functions - production, distribution, exchange, and consumption which, on the one hand, have an impact on the exploitation of natural resources, and on the other bring about waste generation. Only a correct treatment of waste may produce multiple benefits.

Published: March 2021

We investigated the charged micron-sized particle separation by the alternating electric field in a linear quadrupole electrodynamic trap in open air under standard atmospheric temperature and pressure conditions (STP). In experiments we varied the amplitude of the alternating voltage supplying the electrodynamic trap and used a mixture of charged glassy carbon and alumina particles. The carried out numerical simulations and experimental results showed the mutual influence of the amplitude and frequency of the supplied to the trap electrode voltage on the separation of the different sizes particles. The typical particle charges in simulations were approximately equal to experimentally measured values obtained in a corona discharge.

Authors: Pavić Slađana , Maričić Ljubisav , Vujović Mira , Janković Ivan , Pavić Aleksandra
Published: March 2021

Introduction: Fulminant hepatitis is a severe acute liver disease. It occurs due to massive necrosis of hepatocytes. The disease progresses to lethal outcome within a few days. The most common causes of this disease are toxic substances, autoimmune and viral hepatitis. The aim of the study was to present a lethal case of fulminant hepatitis caused by hepatitis B virus in a patient with treated bladder cancer. Case Outline: A 63-year-old patient was admitted for treatment due to weakness, nausea and decreased diuresis. She had surgery to remove her bladder, which was affected by a malignant process, two years earlier. On admission, she had a subicteric, orderly auscultatory finding. The abdomen was palpably painful below the right costal arch, without organomegaly. The ureterostomy was functional. The diagnosis of acute HBV infection was made by evidence of HBsAg, HBeAg and antiHBc IgM antibody titer. Laboratory findings indicated an increase in transaminases, urea, creatinine, total and conjugated bilirubin, decreased albumin values and coagulation disorders. The patient was treated with hepatoprotective therapy, antibiotics and antiviral therapy. Hemodialysis was performed as needed. Encephalopathy developed on the third day with further progression.The disease progressed with gastrointestinal bleeding and cardiac disorders and ended in death on the ninth day. Conclusion: Fulminant liver damage caused by hepatitis B virus is a severe disease that can be complicated by acute renal failure. The prognosis of the disease is often unfavorable, so optimal treatment requires a liver transplant.

Authors: Stojković-Zlatanović Sanja
Published: March 2021

IV industrial revolution and digitalization of production and labour have a positive impact on economic and social development. However, consideration and analysis of the challenges of adapting the existing international legal framework in terms of guidelines for redefining national policies and responding to changes in the field of work are necessary to ensure decent working conditions and protection of the basic rights of employees. By applying the normative, comparative-legal, and axiological method, the paper aims to identify basic legal issues of the status of workers regarding changes caused by the IV industrial revolution. After determining the theoretical-conceptual framework of the so-called platform work, the advantages and disadvantages of using Internet technology in the field of work, as well as possible ways to eliminate them are pointed out. Furthermore, a special focus is on the application of the Internet of Things technology in the field of health and safety at work. The worker-oriented concept in terms of a holistic and integrative approach to the subject of the research should result in the establishment of basic legal assumptions of the regulatory and normative framework of new forms of work.
Metabolic syndrome in the population of psychiatric patients in Novi Sad
Authors: Kuljančić Dušan
Published: March 2021

OBJECTIVES: The aim of this study is to determine the prevalence of metabolic syndrome (MetS) in a sample of hospitalized patients and to relate it to socio-demographic characteristics, psychiatric diagnosis and psycho-pharmacotherapy. METHODS: The study was conceived as a retrospective cohort study. Data of interest for this research were collected from the medical history of hospitalized patients at the Clinic for Psychiatry KCV in the period from January 2018 to January 2020. RESULTS: Out of a total of 2409 patients hospitalized at the Psychiatric Clinic, 1327 patients had criteria for metabolic syndrome, with a high prevalence of 55.1% among this population. Although there are more respondents in the sample (55.7%), males with a diagnosis of MetS (58.1%) dominate. The data show that the prevalence of metabolic syndrome increases statistically significantly with the age of psychiatric patients. However, the prevalence of metabolic syndrome in the study population younger than 30 years is about 33%. Among patients with incomplete primary school, 67% have a diagnosis of metabolic syndrome, which is statistically significantly higher than other compulsory profiles (p <0.001). The study sample shows a statistically significantly higher prevalence of metabolic syndrome among patients treated for psychotic disorders, with as much as 67% prevalence. Therapy with atypical antipsychotics was most associated with metabolic syndrome in 67.5% of patients, followed by a combination of 2 or more antipsychotics with 60.7% (x²=26.99, p<0.0019). Abdominal obesity is the strongest predictor of the response that the subjects will suffer from the metabolic syndrome, the quotient of which is 1.34 by logistic regression. Another important predictor refers to triglyceridemia, whose probability quotient is 1.12. CONCLUSION: The prevalence of metabolic syndrome in psychiatric patients in Novi Sad is alarmingly high, in more than half of patients, especially those treated for psychotic and mood disorders and using atypical antipsychotics and combinations of antipsychotics. In a patient with metabolic syndrome there is male dominance, low educational profile and the prevalence increases statistically significantly with increasing age of psychiatric patients.

Filología y pintura conceptual: Análisis de dos obras de Hilario Bravo
Authors: Garcia-Manso Angelica , Tovar Paz Francisco Javier
Published: March 2021

La creación pictórica de Hilario Bravo responde a una reflexión sobre la escritura, sobre la capacidad del arte pictórico para convertirse en texto y, a la inversa, acerca de las formas de los alfabetos y las lenguas que estos vehiculan. Se analizan las obras Fontis patet (2014) y “El tríptico de Freya” (2017) a partir de las expresiones en latín presentes en las mencionadas pinturas. Se concluye que el pintor utiliza la reflexión sobre la escritura como una exégesis conceptual del paisaje o entorno en tanto las variaciones lingüísticas en los lemas (en lengua latina en las obras estudiadas) suponen un esfuerzo hermenéutico de los cambios que se descubren en el hábitat objeto del cuadro.

Hilario Bravo's paintings are a reflection on writing, on the capacity of pictorial art to become text and, conversely, on the forms of alphabets and the languages they convey. The works Fontis patet (2014) and "Triptych about Freya" (2017) are analysed on the basis of the Latin expressions present in the aforementioned paintings. It is concluded that the painter uses the reflection on the writing as a conceptual exegesis of the landscape or environment in as much the linguistic variations in the lemmas (Latin lemmas in the studied works) suppose a hermeneutic effort of the changes that are discovered in the habitat object of the painting.
La Murcia modernista de los siglos XIX-XX. Autores del modernismo y el asentamiento del trovo o poesía popular repentizada como arte escénico
Authors: Tomás Loba Emilio del Carmelo
Published: March 2021

Desde que en 1880 comienza oficialmente el periodo conocido como Modernismo, en la región de Murcia, la corriente fue asumida con el mismo grado de rechazo si bien es cierto que autores como Ricardo Gil dejaron entrever en su pluma la influencia parisina de la que hará gala Rubén Darío como figura literaria mundial indiscutible. Lo cierto es que, en ese cambio de siglo convulso, y debido al capital extranjero, el territorio del sureste español emerge en el sector primario de la minería, y es en ese contexto minero donde el modernismo arquitectónico eclosiona, pero también en torno al denominado Café Cantante, la representación poética del Trovo o poesía oral improvisada, evolucionando así de la calle y el ámbito tabernario, al arte escénico.

Since the period Known as Modernism officially began in 1880, in te Murcia region, the current was assumed with the same degree of rejection, although it is true that authors such as Ricardo Gil, hinted at the Parisian influence of wich Rubén Darío will show off as the undisputed world literary figure. The truth is that, in this turbulent turn of the century, and due to foreign capital, the territory of the Spanish southeast emerges in the primary sector of mining, and it is in this minig context, where architectural modernism hatches, but also, around the so-called Café Cantante, the poetic representation of the Trovo or improvised oral poetry, thus evolving from the Street and the tavern enviroment, to performing art.

Internet of Things (IoT) devices often lack device cybersecurity capabilities their customers-- organizations and individuals--can use to help mitigate their cybersecurity risks. Manufacturers can help their customers by improving how securable the IoT devices they make are by providing necessary cybersecurity functionality and by providing customers with the cybersecurity-related information they need. This publication describes recommended activities related to cybersecurity that manufacturers should consider performing before their IoT devices are sold to customers. These foundational cybersecurity activities can help manufacturers lessen the cybersecurity-related efforts needed by customers, which in turn can reduce the prevalence and severity of IoT device compromises and the attacks performed using compromised devices.
La revendication d’un titre ancestral sur le domaine privé au Québec
Authors: Otis Ghislain
Published: March 2021

Dans le présent article, l’auteur s’attache à préciser le cadre juridique pour la résolution en droit québécois d’une revendication de titre ancestral sur une propriété privée. Ce type particulièrement sensible de revendication autochtone a été, à ce jour, principalement observé dans les provinces régies par la common law où la doctrine a par ailleurs déjà réfléchi de manière approfondie sur le sujet. L’auteur veut ici entamer la réflexion au regard du contexte civiliste québécois. Dans la première partie de son étude, il démontre que ni l’aliénation du domaine public au profit de particuliers ni les règles de prescription n’ont pour effet d’éteindre le titre ancestral, lequel peut dès lors fonder une action en revendication à l’encontre d’un propriétaire privé. La deuxième partie sert à montrer que, à défaut de pouvoir invoquer les recours de droit commun qu’accorde le Code civil du Québec au propriétaire, le peuple autochtone peut demander la protection de son bien en vertu de la Charte des droits et libertés de la personne. Dans la troisième et dernière partie, l’auteur examine les arbitrages envisageables dans le contexte de l’article 9.1 de cette charte et jauge la conformité de ces solutions aux exigences de la Constitution. Il fait valoir que, bien que la restitution en nature ne soit peut-être pas la réparation la plus fréquemment octroyée au peuple autochtone, elle s’imposera dans certains cas. Des formules de restitution partielle ou par équivalence seront aussi à la disposition du tribunal qui devra en outre s’assurer que la Couronne se conformera à son obligation de fiduciaire.

Este artículo tiene por objetivo analizar la emergencia de Nuevos Movimientos Sindicales (NNMMSS) vinculándola a la oportunidad de revitalización que puede suponer para las contemporáneas centrales sindicales mayoritarias, hijas del taylorismo-fordismo. Para ello, nos centramos en el análisis de sus aportaciones. A nivel teórico, estudiamos el alcance de las críticas vertidas al actual modelo de representación salarial, resaltando la necesidad de asumir la teoría de la oferta y la importancia de los factores internos para afrontar la citada revitalización. Y a nivel práctico, señalamos su apuesta por la horizontalidad en las tomas de decisiones de colectivos con menor representación histórica y por prácticas de afiliación múltiple que cuestionan tanto el reparto del poder como los límites de la negociación colectiva. Estas son las principales conclusiones extraídas de un estudio llevado a cabo en Cataluña. Cualitativamente nos hemos basado en la realización de entrevistas semiestructuradas a representantes cualificados de sindicatos mayoritarios y minoritarios, de NNMMSS y miembros de asociaciones empresariales y expertos académicos, junto al análisis crítico de la literatura científica vinculada.

Authors: Liu Yawei
Published: March 2021

The development of opera genre in Europe and Russia in the XIX century is of particular interest for the Chinese and Russian art historians. The subject of this article is the history of European and Russian opera in the XIX century. The object of this research is the works of the leading opera composers and the novelties introduced by each of them into the opera genre. The goal consists in examination of the following aspects of the topic: specificity of emergence of opera in Russia in the XVIII century, establishment of the national opera schools – Italian, French, German and their prominent representatives, as well as peculiarities of the Russian opera tradition of the XIX century. The novelty lies in determination of similarities and differences between the European and Russian opera in the XIX century from the perspective of of Chinese art history. The author's special contribution consists in the attempt to discuss the subject matter in the context of Chinese art historians who take interest in the peculiarities of opera of the XIX century. The acquired results demonstrate that the development of opera within the framework of the vocal and musical performance in the XIX century is a unique sociocultural phenomenon, which manifested through the system of spiritual values and spiritual life of the Russian and European nations.
The Implementation of Industry 4.0 Elements as a Tool Stimulating the Competitiveness of Engineering Enterprises
Authors: Kubickova Lea , Kormanakova Marcela , Vesela Lucie , Jelinkova Zdenka
Published: March 2021

The article deals with the implementation of Industry 4.0 elements in Czech engineering companies in connection with the impact of this trend on the relationship between supplier and customer. The implementation of Industry 4.0 elements can have a positive effect on the relationship between supplier and customer through higher labour productivity, higher product quality as well as shorter production or delivery times. Industry 4.0 brings great opportunities for companies, which can mean greater efficiency and competitiveness; on the other hand, there are questions about whether companies are ready for it, i.e. whether there is sufficient infrastructure necessary to put Industry 4.0 into practice. The aim of this article is to identify the specifics of supplier-customer relationships in engineering which respond to the current trends and to find out how Czech engineering companies have implemented specific elements of Industry 4.0. No study of this kind has ever been conducted in the environment of Czech engineering companies. Based on the analysis of primary data obtained from 236 Czech engineering companies, the current trends in the management of relations between suppliers and customers are described; Czech engineering companies can use our results to increase their competitiveness. Emphasis is placed on Industry 4.0, planned investments in this infrastructure and the implementation of individual elements. Of the elements of Industry 4.0, Czech engineering companies mostly use tools and methods ensuring data security, automation of technological equipment and processes, cloud computing, mass customization and introducing sensors into production. Our results show that the investment in the necessary infrastructure is mainly related to the size of the company, with almost half of the large companies surveyed planning to invest in the infrastructure necessary to implement Industry 4.0 elements, while 46% of micro-enterprises do not plan to invest in Industry 4.0 elements.
Assessing the Intermediary Role of Relationship Ending Capability and Dark Side Between Network Embeddedness and SMEs’ Innovation Performance
Authors: Tian ongyun , Dogbe ourage Simon Kofi , Bamfo Bylon Abeeku , Pomegbe Wisdom Wise Kwabla , Borah Prasad Siba
Published: March 2021

A key driver of firm competitive advantage is the firm’s ability to develop along with the everchanging business environment and associated market demands by being innovative. Small and medium-sized enterprises (SMEs), however, often lack adequate resources to develop innovation, so they search for external resources to augment the deficiency of their internal resources. Network embeddedness has many advantages for the firm, but it also has a dark side which has a negative effect on the network relationship. In order to take advantage of a network, firms should cultivate the capability to deal with the dark side of inter-firm relationships. Firstly, this study assesses the effect of network embeddedness on the innovation performance of SMEs. Secondly, the authors investigated the moderating role of this dark side in the relationship between network embeddedness and the innovation performance of SMEs. Finally, the role of relationship ending capability in neutralizing the negative effect of dark side we presented. Empirical analysis was based on 388 SMEs. Various validity and reliability checks were conducted before the presentation of the analysis itself, which was conducted using the ordinary least squares approach in SPSS (v.23). The findings showed the dark side negatively moderated the relationship between network embeddedness and the innovation performance of SMEs. This negative effect is, however, reduced by SMEs with a high relationship ending capability by freeing up firm’s limited resources for more fruitful business relationships.
Beyond Habitat
Authors: Safdie Moshe
Published: March 2021

Habitat was one of the most intriguing buildings in the world when it opened as the housing exhibit of Expo 67 in Montreal. Seven million visited it; heads of state lived in it; models flew half way around the world to pose in front of it; children played hide-and-seek all over it; and critics heralded it as “the breakthrough of twentieth century architecture.”

As intriguing as the bilding is the story of how it came to exist. Here, in Beyond Habitat, its young architect Moshe Safdie describes – with a frankness that permits a rare view behind the scenes of modern architecture and mass housing – how his ideas developed and how he fought them into realization. It is a personal statement – almost a private diary and photo album, often containing observations “of a kind one confides only to a friend.”

Safdie tells his story now because he believes that what lies beyond Habitat, what Habitat presaged, is even more significant then Habitat itself. In each of his projects since, he has tried to advance the work Habitat began: in Habitat Puerto Rico (now under construction); in Habitat Israel, the 1,500 dwelling system covering a mountainside outside Jerusalem; in the design for a union building commissioned by students of the San Francisco State College which, when rejected by state officials, became a symbol influencing the campus uprising; in a spectacular suspension building system for the New York waterfront.

Safdie's work points to a new kind of environment:

... factory built cities where modern technology, far from regimenting, is used to liberate man to a wider choice of environment than he has ever known

... three dimensional cities reaching upwards with streets in the sky, gardens on rooftops, dwellings open on three sides to air and space and sun

... creative cities where the cultural riches of a high density environment combine with the quiet and privacy of low density to give men the best of both worlds

... and, most important of all, cities that would express a contemporary vernacular, be so harmony with man's spirit that he would no longer need arbitrary design, inappropriate furnishings and irrelevant art to help him forget the ugliness around him.

To achieve such an environment, Safdie believes we must change most of our present attitudes toward government, housing, industry, design and art. Governments must set themselves new action for cities, laws, taxes; they must adopt new environmental codes. Industry must undertake the kind of research in building materials it did for automobiles and airplanes. Contractors must reorganize their methods of working. Unions must give up present division of trades. Building codes and by-laws must be updated.

In all of this Habitatit Montreal was the beginning. The struggle to get Habitat built is indicative of the kind of the stuggleo build the new city, The fact that Hahitat di get built is casue for hope,
Survey of Architectural History in Cambridge
Authors:   Cambridge Historical Commission
Published: March 2021

This series, called the Survey of Architectural History in Cambridge, was among the first inventories of its kind in America.

Shortly after the Cambridge Historical Commission was established it embarked on the task of surveying Cambridge's architectural resources. The Commission published five reports, from 1964 to 1977, on each area of the city. This series, called the Survey of Architectural History in Cambridge, was among the first inventories of its kind in America. This new edition of East Cambridge, the first report, appears at a time when the neighborhood is experiencing increasing development pressures, making it a particularly valuable resource on the area's history and growth for residents, planners, and outside investors. Although its primary focus remains architectural, the second edition includes the results of extensive primary source research on the district's colonial history, industrial development, and social history. It breaks new ground by correlating city directory and census data with the types of workers' housing built in the period from 1820 to 1870. Development is not new to East Cambridge. Established on an isolated island in the salt marshes opposite Boston in 1809, it became the first part of Cambridge to undergo industrial expansion and attracted great numbers of immigrants during the mid-nineteenth century. The substantial Federal brick houses built on speculation by the Lechmere Point Corporation gave way to modest workers' cottages in the early 1820s. This building type soon became characteristic of the community densely populated, working class, with a distinctive architecture that still largely survives.

Mice emit ultrasonic vocalizations (USVs) that communicate socially relevant information. To detect and classify these USVs, here we describe VocalMat. VocalMat is a software that uses image-processing and differential geometry approaches to detect USVs in audio files, eliminating the need for user-defined parameters. VocalMat also uses computational vision and machine learning methods to classify USVs into distinct categories. In a data set of >4000 USVs emitted by mice, VocalMat detected over 98% of manually labeled USVs and accurately classified ≈86% of the USVs out of 11 USV categories. We then used dimensionality reduction tools to analyze the probability distribution of USV classification among different experimental groups, providing a robust method to quantify and qualify the vocal repertoire of mice. Thus, VocalMat makes it possible to perform automated, accurate, and quantitative analysis of USVs without the need for user inputs, opening the opportunity for detailed and high-throughput analysis of this behavior.

Although the function of microRNAs (miRNAs) during embryonic development has been intensively studied in recent years, their postnatal physiological functions remain largely unexplored due to inherent difficulties with the presence of redundant paralogs of the same seed. Thus, it is particularly challenging to uncover miRNA functions at neural circuit level since animal behaviors would need to be assessed upon complete loss of miRNA family functions. Here, we focused on the neural functions of MiR34/449 that manifests a dynamic expression pattern in the spinal cord from embryonic to postnatal stages. Our behavioral assays reveal that the loss of MiR34/449 miRNAs perturb thermally induced pain response thresholds and compromised delicate motor output in mice. Mechanistically, MiR34/449 directly targetSatb1andSatb2to fine-tune the precise number of a sub-population of motor synergy encoder (MSE) neurons. Thus, MiR34/449 fine-tunes optimal development of Satb1/2oninterneurons in the spinal cord, thereby refining explicit sensory-to-motor circuit outputs.

Background

Totoaba,Totoaba macdonaldi, is an endemic species of the Gulf of California, where wide variations in sea temperature throughout the year, surface salinities that gradually increase towards the north, and contamination by discharge of wastewater have been recorded. In addition to the challenges of reproduction and swimming, its characteristic biannual migration presents totoaba with changes in environmental factors that could affect oxidative stress indicators. The objective of this study was to assess spatial and seasonal changes in the oxidative stress indicators in muscle samples of totoaba.

Methods

Reactive oxygen species production, antioxidant enzyme activities and lipid peroxidation levels were quantified by spectrophotometry.

Results

Results suggest spatial-temporal variations of the oxidative stress indicators in muscle of totoaba that may be associated to a complex interaction between environmental and biological factors, including reproduction and nutrient availability. These results contribute to explain the appeal of totoaba as a marketable meat and suggest totoaba may provide antioxidant nutrients to consumers.
Effectiveness of Video Assisted Teaching on Knowledge among ASHA Workers Regarding HPV Infection in a Selected Rural Community of Mangaluru, India
Authors: Fernandes Philomena , Nayak Sabitha
Published: March 2021

Introduction: Human Papilloma Virus (HPV) is a major aetiological agent for cervical cancer, the second most common cancer in the world. The main role of Accredited Social Health Activist (ASHA) includes, motivating women to give birth in hospitals, bringing children to immunisation clinics, encouraging family planning, treating minor ailments, keeping demographic records, and improving village sanitation. In the community, ASHA create awareness on health and its social determinants and mobilise the community towards local health planning and increased utilisation and accountability of the existing health services. Aim: To evaluate the effectiveness of video-assisted teaching on knowledge regarding HPV infection among ASHA workers. Materials and Methods: A pre-test post-test design was adapted for this study. Fifty-eight ASHA workers were selected using a convenience sampling method. A pre-test was conducted to assess the existing knowledge on HPV infection with the help of structured knowledge questionnaire, followed by Video-Assisted Teaching on HPV infection and seven days later a post-test was done. Interpretation of score of knowledge questionnaire between 1-5 was considered as poor knowledge, 6-10 an average knowledge, 11-15 good knowledge and 16-20 excellent knowledge. Data were analysed using descriptive statistics and inferential statistics. The p-value less than 0.05 were considered to be significant by Z-test. Results: The knowledge of HPV infection was improved noticeably after the video-assisted teaching program as the pre-test mean knowledge score was 7.19±2.55, and the post-test score was 13.10±1.95 at p<0.05. Statistically significant effectiveness of the video-assisted teaching program was established using Willcoxon signed-rank test (Z-value=-6.56 with p<0.05); however, no significant association was found between the pre-test level knowledge and demographic variables. Conclusion: Knowledge of HPV infection among peripheral community workers is vital as it can influence the broader population and avoid this preventable disease condition at the grass root level. The current study revealed that a video-assisted teaching program on HPV infection effectively improved the knowledge level of ASHA workers.
CT Imaging in Gastrointestinal Stromal Tumour: A Case Series

Published: March 2021

Gastrointestinal Stromal Tumours (GISTs) being most common non-epithelial tumours comprise a bunch of non-epithelial smooth muscle, mesenchymal alimentary tract tumours, appearing from the interstitial cells of Cajal of varying malignancy which specify KIT protein-CD117, a stem cell factor receptor. The mutations seen in GIST’s are most common in the proto-oncogene c-KIT; seen only in GIST. This gene is not seen in the other mesenchyamal tumours. Here, the mutated c-KIT helps in the growth and survival of this tumour by activation of the KIT receptor tyrosine kinase. The incident of GISTs is increasing in recognition and the increased rate of survival has made imaging seemingly important, not only for diagnosis, but also for monitoring the effects of treatment and detecting progression of the tumour. The clinical symtoms in this case series include pain abdomen, nausea, vomiting and constipation. Some cases can present as abdominal distension. The investigation of choice for these spectrum of diseases is currently Computed Tomography (CT), however many imaging techniques, such as Positron Emission Tomography (PET), fluorine 18 Fluorode-Oxyglucose (FDG), Magnetic Resonance (MR) imaging, and Ultrasonography (US) can also be used. This article describes the typical imaging findings of GISTs at initial presentation. Many cases present late and at a stage where surgery will not be of much use. However, Imatinib has showed a drastic response in prognosis and helps increasing the survival changes leading a normal life. This study helps us in identifying the pattern of the lesion and its enhancement patterns leading to early detection, thus aiding the surgeon or the oncologist to plan for treatment.
