Authors: Manokaran Kalaivani , Krishnananda Rao Vasanthalaxmi , . Nilima , Shimoga Durgoji Rao Manjula , Prasanna Kumar Sucheta
Published: December 2020

Introduction and Aim: Oxidative stress plays a very important role in endosulfan-induced toxic effects on reproductive organs. Vitamin C is a potent antioxidant which plays an important role in decreasing oxidative stress. The present study was aimed to investigate the protective role of vitamin C against endosulfan-induced testicular toxicity in Wistar rats. To investigate a protective effect of vitamin C against endosulfan induced toxicity on biochemical changes.

Materials and Methods: Seventy male neonatal Wistar rats were divided into  seven groups. The group  I was taken as the control group, the endosulfan-treated were grouped into II (3 mg/kg body weight (BW) and group III (6 mg/kg BW), Group IV (9 mg/kg BW) and Group V (12 mg/kg BW). Group VI (9 mg/kg BW) and group VII (12 mg/kg BW) were pretreated with vitamin C (20 mg/kg BW) for 60 days. After  the experimental procedures, the testicular weight, lactate dehydrogenase (LDH) enzyme and testosterone in plasma, LDH, steroidogenic enzymes 3?-HSD and 17?-HSD in testis were evaluated. One-way ANOVA was used to determine the statistical significance.

Results: Significant improvement in the testicular weight (P<0.05) , LDH (P<0.05) levels both in plasma and testis, increase in testosterone(P<0.001) and steroidogenic enzyme levels(P<0.001) was observed in the group pretreated with vitamin C treated group when compared to the endosulfan treated group.

Conclusion: Vitamin C decreases the toxic effect of endosulfan on testis. The present action might be  due to its antioxidative properties.

Published: December 2020

Introduction and Aim: Breast cancer accounts for about 30% of all cancers in women. The present study aims to see the role of prolactin and Vitex agnus fruit extract in breast cancer progression in mammary tumor induced Sprague Dawley (SD) rats.

Materials and Methods: Thirty-day old inbred SD female rats of body weight 70-80 grams were taken for this study. The rats were induced with N- Methyl-Nitroso-Urea for mammary tumor development. After the development of palpable and visible tumor the rats were treated with anti-prolactin drug (Cabergoline) and a prolactin lowering herb Vitex agnus Castus (VAC) for two months. After the treatment the rats were sacrificed for antioxidants estimation and histopathological section examination.

Results: The rats treated with anti-prolactin drug showed benign tumors with hyperplasia and lactational change proving the presence of prolactin in the tumor tissue, whereas the plant extract showed mammary tumor regression by the presence of foamy macrophages in the histopathological sections. Results also showed treatment with cabergoline increased the GSH level and decreased the MDA level compared to tumor induced group.

Conclusion: Prolactin may have a potential role in progression of breast cancer and Vitex agnus extract showed a prolactin lowering effect and facilitated in regression of the tumor.
Climate change, vulnerability, social conflicts and human displacement in the Andes: The case of Huaytapallana glacier
Authors: Altamirano Teofilo
Published: December 2020

La región andina, en particular el Perú, ha sido clasificada como la tercera región más vulnerable al cambio climático en el mundo (Trigoso 2008); además, a pesar del crecimiento económico de los últimos quince años, más de un tercio de la población vive en la pobreza, lo que aumenta su vulnerabilidad a los diversos efectos del cambio climático, como el retroceso de los glaciares, la pérdida de diversidad biológica, la salud, la producción agrícola y la escasez de agua. En la actualidad, el 65 por ciento de los conflictos sociales están relacionados con cuestiones ambientales, según diversos estudios. En las últimas seis décadas, Perú, como país tropical, ha experimentado cambios significativos en los niveles de precipitaciones y temperaturas, lo que ha provocado un mayor retroceso de los glaciares e inundaciones (Foresight Report 2011). El aumento de los riesgos y peligros ambientales, si bien es de carácter mundial, tendrá más repercusiones locales, en particular en el desierto costero y en las comunidades campesinas andinas (Blaikie y Cannon 2003). En las zonas costeras y áridas, el 80 por ciento del agua dulce proviene de los glaciares, lagos y ríos andinos. Durante los últimos diez años en la costa, la agricultura de regadío ha aumentado, ya que la mayor parte de esta producción se destina a la exportación. Esta producción incluye frutas, flores, espárragos, etc., que requieren más agua que la producción ganadera. Últimamente, se ha informado sobre la escasez de agua y los consiguientes conflictos sociales entre los grandes, medianos y pequeños productores.

Desde 1972 a área de Design está presente na Universidade Federal de Pernambuco. No entanto, o Departamento de Design [dDESIGN] foi criado apenas em 1997, sendo o seu grupo de professores oriundos dos departamentos de Desenho e de Teoria da Arte e Expressão Artística do Centro de Artes e Comunicação. Tais departamentos foram, no passado, responsáveis pelos cursos de Desenho Industrial e suas habilitações em Programação Visual e Projeto do Produto. Atendendo à imensa demanda e, enfim, reunindo condições de maturidade do corpo docente, produção acadêmica e infraestrutura, foi criado em 2004 o Programa de Pósgraduação em Design da UFPE [PPGDesign UFPE] com o curso de Mestrado Acadêmico em Design stricto sensu, o terceiro no Brasil. Junto às especializações lato sensu em Design da Informação e em Ergonomia, o Mestrado Acadêmico em Design da UFPE passou a formar pesquisadores capacitados à docência nas instituições de ensino superior que à época surgiam no Norte e Nordeste do país. Já o curso de Doutorado, foi criado em 2010 como decorrência natural da qualidade do curso de Mestrado e da expansão das atividades de pesquisa potencializadas pelo programa no dDesign.

Calibrating a long-term meteoric 10Be delivery rate into eroding western US glacial deposits by comparing meteoric and in situ produced 10Be depth profiles
Authors: Clow Travis , Willenbring Jane K. , Schaller Mirjam , Blum Joel D. , Christl Marcus , Kubik Peter W. , von Blanckenburg Friedhelm
Published: December 2020

Abstract. Meteoric 10Be (10Bemet) concentrations in
soil profiles have great potential as a geochronometer and a tracer of Earth
surface processes, particularly in fine-grained soils lacking quartz that
would preclude the use of in situ produced 10Be (10Bein situ). One
prerequisite for using this technique for accurately calculating rates and
dates is constraining the delivery, or flux, of 10Bemet to a site.
However, few studies to date have quantified long-term (i.e., millennial)
delivery rates, and none have determined a delivery rate for an eroding
soil. In this study, we compared existing concentrations of 10Bein situ with new measurements of 10Bemet in eroding soils sampled
from the same depth profiles to calibrate a long-term 10Bemet
delivery rate. We did so on the Pinedale (∼ 21–25 kyr) and Bull
Lake (∼ 140 kyr) glacial moraines at Fremont Lake, Wyoming
(USA), where age, grain sizes, weathering indices, and soil properties are
known, as are erosion and denudation rates calculated from 10Bein situ. After ensuring sufficient beryllium retention in each profile,
solving for the delivery rate of 10Bemet, and normalizing for
paleomagnetic and solar intensity variations over the Holocene, we calculate
10Bemet fluxes of 1.46 (±0.20) × 106 atoms cm−2 yr−1 and 1.30 (±0.48) × 106 atoms cm−2 yr−1 to
the Pinedale and Bull Lake moraines, respectively, and compare these values
to two widely used 10Bemet delivery rate estimation methods that
substantially differ for this site. Accurately estimating the 10Bemet
flux using these methods requires a consideration of spatial scale and
temporally varying parameters (i.e., paleomagnetic field intensity, solar
modulation) to ensure the most realistic estimates of
10Bemet-derived erosion rates in future studies.
Temporal and spatial variations in three-dimensional seismic
oceanography
Authors: Zou Zheguang , Bakhtiari Rad Parsa , Macelloni Leonardo , Zhang Likun
Published: December 2020

Abstract. Seismic oceanography is a new cross-discipline between geophysics and oceanography that uses seismic reflection data to image and study the ocean water column. Previous works on seismic oceanography were largely limited to two-dimensional seismic data and methods. We present a complete three-dimensional (3D) oceanic seismic study and explore its imaging capability in seismic oceanography. From a 3D multichannel seismic survey acquired for oil and gas exploration in the Gulf of Mexico over six months period, a 3D water-column seismic volume was derived. The 3D seismic volume exhibits both temporal and spatial variations of the ocean, and theoretical and empirical analyses were performed to discriminate their contribution. Our analyses shows that temporal variation is largely embedded along crossline direction, hence deteriorating the quality of seismic images; however, inline sections, which can be seen as snapshot representation of the water column, allow to capture not only thermohaline structure but also the temporal evolution of the ocean dynamics. Our finding highlights that appropriately processed and analyzed 3D seismic data not only provide superior images of the ocean structure but also can be useful for investigation of temporal evolution of mesoscale ocean dynamics.
Laboratory experiments on the influence of stratification and a
bottom sill on seiche damping
Authors: Medjdoub Karim , Jánosi Imre M. , Vincze Miklós
Published: December 2020

Abstract. The damping of water surface standing waves (seiche modes) and the associated excitation of baroclinic internal waves are studied experimentally in a quasi-two-layer laboratory setting with a topographic obstacle at the bottom, representing a seabed sill. We find that topography-induced baroclinic wave drag indeed contributes markedly to seiche damping in such systems. Two major pathways of barotropic-baroclinic energy conversions were observed: the stronger one – involving short-wavelength internal modes of large amplitudes – may occur when the node of the surface seiche is situated above the close vicinity of the sill. The weaker, less significant other pathway is the excitation of long waves, internal seiches along the pycnocline that may resonate with the low frequency components of the decaying surface forcing.
Coupled dynamics and evolution of primordial and recycled
heterogeneity in Earth's lower mantle
Authors: Gülcher Anna Johanna Pia , Ballmer Maxim Dyonis , Tackley Paul James
Published: December 2020

Abstract. The nature of compositional heterogeneity in Earth’s lower mantle remains a long-standing puzzle that can inform about the long-term thermochemical evolution and dynamics of our planet. Here, we use global-scale 2D models of thermochemical mantle convection to investigate the coupled evolution and mixing of (intrinsically-dense) recycled and (intrinsically-strong) primordial heterogeneity in the mantle. We explore the effects of ancient compositional layering of the mantle, as motivated by magma-ocean solidification studies, and of the physical parameters of primordial material. Depending on these physical parameters, our models predict various regimes of mantle evolution and heterogeneity preservation over 4.5 Gyrs. Over a wide parameter range, primordial and recycled heterogeneity are predicted to coexist with each other in the lower mantle of Earth-like planets. Primordial material usually survives as mid-to-large scale blobs (or streaks) in the mid-mantle, around 1000–2000 km depth. This preservation is largely independent on the initial primordial-material volume. In turn, recycled oceanic crust (ROC) persists as large piles at the base of the mantle and as small streaks everywhere else. In models with a dense FeO-rich layer that is initially present at the base of the mantle, the FeO-rich material partially survives at the top of ROC piles, causing the piles to be compositionally stratified. Moreover, the addition of an ancient FeO-rich basal layer in the lowermost mantle significantly aids the preservation of the viscous domains in the mid-mantle. Primordial blobs are commonly (but not always) directly underlain by thick ROC piles, and aid their longevity and stability. The preservation of primordial domains along with recycled piles is relevant for Earth as it may reconcile geophysical and geochemical constraints on lower mantle heterogeneity.

Published: December 2020

This work presents a failure diagnosis tool for a water pump using a low-cost MEMS accelerometer. It was inserted three types of failures: rotor blade (new and damaged), pump soleplate tightness (stiff or loose), and cavitation, in this case on three conditions: none, incipient and severe, totaling twelve fault combinations. These conditions were tested under two different speeds to perform the diagnosis, totaling twenty-four tests. In all cases, the vibration signals from axes X, Y, and Z were acquired. Some features extracted from the vibration spectra from X-axis were used to compose the dataset. These data were analyzed employing logistic regression, a linear support vector machine (SVM), and an artificial neural network multilayer perceptron (ANN-MLP). We compared these three techniques of machine learning and evaluated which one was able to obtain the most accurate result. Using the ANN-MLP, the system was able to detect all three types of failures inserted, with about 100% of accuracy on the rotor blade condition, 92% for anchorage faults, and about 99% accuracy on cavitation state. As a conclusion, it is demonstrated that this classifier algorithm can be used to process the data from the low-cost MEMS accelerometer in predictive maintenance as an accurate tool.

The goal of this research was to evaluate the chemical composition of some herbal products consumed in Brazil through the Energy Dispersive X-ray Fluorescence (EDXRF). The methodology used encompassed the selection of 14 plants’ dried extracts and six ground plants. The qualitative and quantitative analyses of samples indicating the presence of As, Cr, Cu, Fe, Ni, Zn, Si, P, S, Cl, K, Ca, Ti, V, Mn, Co, Rb, Zr, Cd, Sn, Ba, Hg, Pb, Bi, Mo, and Pt in different concentrations. It is feasible that part of the contamination found in the herbal products come from the adjuvants/excipients used in the production process. Also, it was found that the extract production process seems to have a low efficiency for the extraction of the main chemical elements present in the ground plants. In the other hand, it has the benefit of reducing the contamination by harmful elements to health, such as heavy metals. EDXRF can replace atomic absorption spectrometry as low-cost and high precision technique to quantify all elements of interest in the pharmaceutical and food industries, within the limits established by regulatory agencies
Tecnologia assistiva em dispositivos móveis: aplicativos baseados no TEACCH como auxílio no processo de alfabetização com crianças autistas
Authors: Reis Marlene Barbosa de Freitas , Souza Carla Salomé Margarida de , Dos Santos Lilian Cristina
Published: December 2020

Progressivamente emerge a necessidade de redimensionar práticas pedagógicas que, para além do respeito às diferenças, ofereça acessibilidade de aprendizagem a todos os discentes. Uma escola com metodologias conservadoras, dificilmente conseguirá bons resultados diante da educação inclusiva, colocando os discentes com deficiências em condições de exclusão, dentro da própria escola. Percebe-se que no redimensionamento dessas práticas, a Tecnologia Assistiva (TA) assume papel primordial, pois visa a superação de barreiras para a aprendizagem e independência na vida social de indivíduos com deficiências ou outras condições que geram necessidades especiais. Isso fomentou a inquietação que deu origem a este estudo: de que forma a Tecnologia Assistiva associada à Tecnologia Móvel em smartphones e tablets pode contribuir com a aprendizagem, mais especificamente com a alfabetização de crianças com Transtorno do Espectro Autista (TEA) na escola regular? Para responder a essa inquietação, desenvolveu-se uma pesquisa de cunho bibliográfico em autores como: bell hooks  (2013), Reis et. al. (2017), Ferreira (2016), Cunha (2017), Furtado (2012), Fonseca e Ciola (2016), Mello (2007), Berch (2007), entre outros. Este artigo apresenta um dos principais métodos educacionais utilizado na educação de crianças autistas, o TEACCH, e faz um levantamento dos usos desse método em dispositivos móveis. Os resultados apontam para a contribuição de dois aplicativos (Lina Educa e ABC Autismo) que podem ser utilizados como ferramentas pedagógicas no processo de aprendizagem de crianças com TEA, auxiliando a inclusão dessas crianças, principalmente no tocante ao processo de alfabetização.
O legado de Paulo Freire à onda neoconservadora: resistência na práxis
Authors: Ramos Nara Vieira , Py Dutra Maria Rita
Published: December 2020

O objetivo deste estudo é refletir sobre o legado de Paulo Freire e os processos possíveis de resistência e permanência a partir da educação popular, no enfrentamento à onda neoconservadora. Tem-se como questão de pesquisa como o legado de Paulo Freire poderá contribuir no arrefecimento da atual onda neoconservadora que atinge a sociedade brasileira, em especial o campo da educação? Trata-se de uma análise predominantemente teórica que busca dialogar com os campos político, econômico e social, dando ênfase à educação. No referencial teórico dialogamos com Freire (1967,1980, 1983), Bobbio, Matteucci Pasquino (1998), Mounk (2019), Apple (2004), entre outros. Ao aprofundarmos essa literatura destacamos três dimensões para compreender o atual momento em que vivemos e destacar possíveis caminhos para a resistência a partir da educação: a trajetória de Freire na construção do inédito viável; a onda neoconservadora na contemporaneidade e a práxis necessária para enfrentar os desafios de uma realidade opressora. Apontamos como possíveis caminhos aprofundar estudos e práticas a partir do legado Freireano, reinventando-o em um processo contínuo de ação-reflexão-ação em busca do sonho na construção da resistência.

Performative potential of a dramatic fairy tale and its inclusion
in the educational and didactic process
Authors: Sibirnaja Maria
Published: December 2020

Specific art practices, which include performance, are especially prevalent in popular culture at the turn of the 20th and 21st century. The concept of ‘performance’ means an action in the process of which creation involves a new experience both for the performer of the action and for the recipient. However, it is necessary to distinguish performance as a type of cultural action, dramatization, and performative potential of a work, creating conditions for influencing the consciousness of a person who, when perceiving a work, becomes a full participant in a creative act. Modern fairy-tale plays written by playwrights based on well-known works or the authors’ own dramatic tales have great performative potential. They connect the game principle, the performativity of a fairy tale, capable of activating empathy, influencing the child’s consciousness through the magic of the word, and the performance of the drama, the goal of which is to involve the young viewer in the show. At the same time, the theatrical performance of fairy-tale plays and the metatheatrical techniques involved in them have a significant visual impact on the young audience, which also contributes to the performative dialogue. The moralizing orientation of modern fairy-tale plays, reflecting the current moral and ethical problems of the society, increases the efficiency of the educational process, and contributes to the fulfilment of modern didactic tasks.
In this article, based on the Russian playwright Anna Bogacheva, an attempt is made to identify those features of modern fairy-tale plays that convey their performative character and didactic potential.
Oh, go to sleep, honey. If you want some chills – you got it. On affect in ASMR
Authors: Łapińska Joanna
Published: December 2020

In the article, the author discusses a new cultural phenomenon known as ASMR in a posthuman perspective, especially from the perspective of new materialism (Karen Barad), studies of things (Bjørnar Olsen, Ewa Domańska) and affective studies (Jane Bennett, Sara Ahmed). The article analyzes selected ASMR videos published on the YouTube website in terms of the affectivity of the objects used in them, arguing that ASMR cultural practices encourage the production of human-non-human assemblages of subjects and objects built of “vibrating matter” (Jane Bennett).
Are we merely “meat”?
Authors: Szarlej Jolanta
Published: December 2020

The book “The Body […] is […] for the Lord, and the Lord for the Body” (1 Cor 6, 13). Biblical Foundations for the Theology of the Human Body by father prof. Tomasz Maria Dąbek OSB touches on a subject that is extremely significant for contemporary people and dramatically current in a world where, on the one hand, medical progress and inventing many new medicines have allowed us to radically prolong human life expectancy and facilitate social activisation of sick and handicapped persons, while on the other hand led to considering human organs as transplants and implants, “spare parts” of sorts (A. Litwińczuk, Ciało człowieka w kulturze. Przegląd zagadnień [Human Body in Culture. A Review]), which has led to “breaking up the integrity of the person.”
If we add to this diagnosis the twentieth-century conceptions of the industrial body (e.g. the body of a factory worker or a soldier), considered in terms of efficiency, productivity, as well as the hedonistic body, subjected to the constant pressure of “the global culture of consumption” (A. Litwińczuk), it will appear that the threat of human beings becoming objectified becomes very real. All the circumstances listed above justify a return to elementary questions about the human nature in relation to the world, God, and other human beings. The answers are to be sought, among other places, in the Bible – a work of fundamental significance for the civilisation of the West – and Tomasz Dąbek’s publication offers useful help in this task.
Okresowe oceny stanu technicznego elewacji budynków
Cz. 7. Elewacje z okładzin kamiennych przyklejanych do ścian
Authors: Runkiewicz Leonard , Kopyłow Ołeksij , Sieczkowski Jan
Published: December 2020

Elewacje z okładzinami kamiennymi przyklejanymi do ścian niewątpliwie należą do grupy najstarszych systemów wykończenia ścian zewnętrznych. Na systemy te składają się: okładziny kamienne, łączniki mechaniczne i zaprawy klejowe. Systemy te były często stosowane w Polsce na budynkach reprezentacyjnych w minionych epoterkach, często objętych opieką konserwatorów zabytków. Niestety czas, oddziaływania środowiskowe i antropogeniczne niekorzystnie wpływają na tego typu elewacje. Awarie omawianych systemów (ze względu na masę okładzin kamiennych) mogą powodować bardzo groźne skutki. Główne przyczyny awarii tych typów elewacji związane są z zaniedbaniami użytkowymi. Zminimalizowanie ryzyka wystąpienia awarii jest możliwe dzięki systematycznemu przeprowadzaniu okresowych ocen stanu technicznego tych elewacji.
W artykule przedstawiono zasady przeprowadzania ocen elewacji z okładzin kamiennych oraz podstawowe zakresy czynności pozwalających określić ich stan techniczny. Opisano również metody eksperckie i badawcze pozwalające na diagnozowanie omawianych systemów elewacyjnych z wymaganymi dokładnościami.
Price discount strategies in times of increasing price transparency: How price consciousness and price comparison moderate the effect of discount strategy on store price image
Authors: Scheidegger Gianluca , Linzmajer Marc , Rudolph Thomas
Published: December 2020

This research uses a large set of price promotion field data to better understand the application of price discount strategies by Swiss grocery retailers. Taking the prevalence of these strategies in the Swiss grocery retail market as a basis, we use an online experiment that builds on recent developments in technology usage by consumers and investigate the impact of price comparison on store price image. The results show that Swiss grocery retailers have increased their number of discounts offered over the observation period of two years. In addition, store price image significantly improved with the number of discounted products offered. On the other hand, discount depth had no influence on store price image. These effects, however, are dependent on consumers’ price consciousness and their (non-) usage of a price comparison tool. Lastly, theoretical and practical implications are being provided.
Cross-Layer Inference in WSN: From Methods to Experimental Validation
Authors: Dey Indrakshi
Published: December 2020

In this chapter, the fundamentals of distributed inference problem in wireless sensor networks (WSN) is addressed and the statistical theoretical foundations to several applications is provided. The chapter adopts a statistical signal processing perspective and focusses on distributed version of the binary-hypothesis test for detecting an event as correctly as possible. The fusion center is assumed to be equipped with multiple antennas collecting and processing the information. The inference problem that is solved, primarily concerns the robust detection of a phenomenon of interest (for example, environmental hazard, oil/gas leakage, forest fire). The presence of multiple antennas at both transmit and receive sides resembles a multiple-input-multiple-output (MIMO) system and allows for utilization of array processing techniques providing spectral efficiency, fading mitigation and low energy sensor adoption. The problem is referred to as MIMO decision fusion. Subsequently, both design and evaluation (simulated and experimental) of these fusion approaches is presented for this futuristic WSN set-up.

The stability analysis carried out by GEO5 software and uses free sliding analysis by wet and pore saturated weight charting provided the safety factor of 1.35. The safety precautions were followed by inclinometers and wire extensometer measurements. The other pore saturated asphalt bound shear box and unaxial test compression tests were resulted in the geotechnical and geoseismical data over sliding soil /shale inter surface quality and the characteristics of free rock falling risk and discontinuity distribution, sub crack density and distribution on stereo nets were determined. The research was firstly followed the perched water levels on geoseismical data over causing water burst or explosion of highly free mud and landslides. The hazardous rock falls over saturated soil and uncohesive rock explosions. The proposed study was secondly as strengthening methods such as asphalt mixing as precautious on shear stabilization and other wire mesh barriers anchored. The free sliding cracks was filled by asphalt and compressed for stabilization strengthening known as the characteristics of avoiding shear falls in the future. The unconditional expectations related to this study was also defined for this region such as the influence of the ground water, rock cracks and slope design, explosion exchange dynamics leading to landslide.

Authors: Li Feng
Published: December 2020

Organic–inorganic hybrid perovskites, which combine the superior optical and electronic properties and solution-processed manufacturing, have emerged as a new class of revolutionary optoelectronic devices with the potential for various practical applications. Encouraged by the advantages of longer carrier diffusion length, higher carrier mobility and lower trap densities as compared to the polycrystalline counterparts’, increasing research attention has focused on preparation and optimization of perovskite crystal candidates, via using various facile growth techniques, for the development of a wide range of optoelectronic applications. This chapter presents a comprehensive review of recent advances in the field of optoelectronic technologies based on different forms of single crystals, including bulk crystals and thin ones, with emphasis placed on the optimization of crystals and the relationship among the charge-carrier transport, operation mechanism, device architecture, and device performance. First, we introduce the main methods used to prepare bulk and thin single crystals, and analyze several aspects of their properties. Thereafter, the applications of single crystals into solar cells, photodetectors, light-emitting diodes, and lasers, are discussed in depth. Finally, we summarize the challenges of perovskite single crystals and propose further improvements in the synthesis approaches and device applications.
Online Career Guidance Systems for PK-12 School Students: Compliments to a Comprehensive School Counseling Program
Authors: A. Cerrito Julie , Joseph Behun Richard
Published: December 2020

The American School Counselor Association (ASCA) identifies three main domains that should be included in a developmental and comprehensive school counseling program. These domains include academic development, social/emotional development, and career development. This chapter will provide an overview of the career development needs of PK-12 students. It will also offer several online career guidance system suggestions that school counselors and educators may employ to meet both the needs of school-aged students and the demands of career guidance and planning during the formative years of elementary, middle, and high school. Research has shown that the area of career development is significantly lacking in school systems and less emphasis is placed on this domain in comparison to others. Therefore, online career guidance systems that may be accessed by students independently or with educator collaboration may help to bridge this gap.

Published: December 2020

Background: Breast cancer is a major cause of female death worldwide. Several factors contribute to cancer development, one of the most important of which is viruses identified by the host immune system and Toll-like receptors (TLRs). Human herpes virus 8 (HHV-8) is one of the viruses with a proven role in Kaposi’s sarcoma development. Objectives: This study aimed to investigate the correlation between HHV-8 infection and breast cancer, as well as the role of rs4986791 polymorphism in women’s health. Methods: Blood samples of 80 healthy subjects and 80 patients suffering from breast cancer were collected (from May-September 2018). The presence of HHV-8 in the samples was examined by PCR. Also, the rs4986791 polymorphism was evaluated by nested PCR-RFLP. Results: The results showed a significant relationship between age and breast cancer. Of 80 cancer patients and 80 healthy subjects, 17 (21.3%) and 15 (18.8%) were carriers of HHV-8, respectively. Also, there was no significant relationship between HHV-8 infection and breast cancer (P = 0.693). We found no significant relationship between the presence of virus and cancer grade (P = 0.618). Conclusions: The results of rs498679 polymorphism analysis indicated that the T allele was associated with increased health phenotype and decreased risk of cancer development. Also, women with TT genotype exhibited significantly lower HHV-8 infection than the other genotypes.
Prophylactic Ablation in Asymptomatic Patients with Wolff-Parkinson-White Syndrome
Authors: Ong Leong Tung
Published: December 2020

Context: Radiofrequency ablation is a highly effective and safe therapy for the management of patients with symptomatic Wolff-Parkinson-White (WPW) syndrome. However, the management of asymptomatic patients with radiofrequency ablation is controversial. This review aimed to investigate whether prophylactic ablation could improve the long-term outcomes of asymptomatic patients with WPW. Methods: A systematic literature search was performed in databases such as PubMed, Google Scholar, and Cochrane Library for the relevant articles published during 2000 - 2020. Only original studies, cohorts, and randomized controlled trials (RCTs) performed on the WPW patients undergoing radiofrequency ablation were selected. Results: In total, six studies were reviewed, some of which suggested that the patients undergoing radiofrequency ablation had a high incidence of atrial fibrillation even after ablation. On the other hand, some of the findings indicated that ablation could reduce the mortality rate of WPW patients. In addition, two RCTs suggested that prophylactic ablation may reduce arrhythmic events in high-risk pediatric and adult patients, while one clinical trial showed no significant risk reduction for arrhythmias in the patients undergoing the prophylactic radiofrequency catheter ablation of the accessory pathways. Conclusions: Available evidence suggests that prophylactic ablation is effective in the prevention of arrhythmic events and sudden cardiac death in asymptomatic patients with WPW. However, the risk of asymptomatic patients becoming symptomatic or sudden cardiac death has been reported to be low. Therefore, only high-risk patients are recommended to undergo prophylactic ablation.

Background: Congenital heart disease (CHD) is the most common congenital disorder in neonates. Many factors are associated with the occurrence of the CHD, including genetic factors, teratogenic exposure and several other unrecognized factors. Objectives: This study aims to investigate the role of several potential factors associated with the occurrence of CHD. Methods: This study was conducted as a cross-sectional case-control study, in Imam Khomeini Hospital Complex, Tehran, Iran. A total of 1338 known cases of CHD, diagnosed by echocardiography or angiography and 1201 healthy children as the controls were included in this study. Factors that could have an association with CHD were investigated by a questionnaire from all participants. Results: Maternal age above 30 years (P-value < 0.001), positive parents’ consanguinity (P-value < 0.001) and previous maternal history of abortion (P-value < 0.001) was significantly higher among patients with CHD; furthermore, positive history of CHD among siblings of the known cases of CHD was higher than healthy ones (P-value < 0.001). The mean birth weight in case and control group were 3 (+ 0.648) and 2.9 (+ 0.707) kilograms, respectively. The maternal age in 983 (73.4%) cases and 960 (79.93%) controls was below the 30 years, the maternal age for other participants was above the 30 years (P-value < 0.001). Conclusions: All factors except the history of stillbirth, maternal underlying disease and drug use during pregnancy in the case group were significantly different with the control group. It seems that the causes of CHD in Iran are most commonly related to the hereditary genetic factors, and the increased maternal age, drug use, and underlying diseases in the mother are a matter of less importance.

Published: December 2020

Background: As the traditional indicators of the operative outcomes, including morbidity and mortality, cannot give sufficient information on a patient’s physical, mental, emotional, and functional well-being alone, we aimed to compare life quality in the patients under open vein harvesting (OVH) and endoscopic vein harvesting (EVH) techniques after four years of follow-up. Methods: This prospective cohort study followed all the patients who were scheduled for off-pump CABG in the Mashhad-based Imam Reza Hospital, in October 2013, for 4 years. Accordingly, data related to their quality of life were collected, and their life quality was then compared using the WHOQOL-BREF scale. Chi-squared, t-test, Fisher exact test, and relative risk were also used. Results: This study was conducted on a total of 103 patients under the two techniques of OVH (n = 53) and EVH (n = 50). The difference between the EVH (4.7%) and OVH (16.3%) groups at the demographic characteristics was the Transient Ischemic Attack (P = 0.023). After a 4-years follow-up period, no significant differences were observed between the patients undergoing the two techniques of OVH and EVH in all the domains of life quality. Conclusions: According to the obtained results, there was no difference in the quality of life between the patients undergoing OVH and EVH techniques over a four-year period. In this regard, further investigations are recommended on the quality of life in patients under the two techniques of OVH and EVH with long-term follow-up periods.
