Effects of physiological changes and social life events on adrenal glucocorticoid activity in female zoo-housed Asian elephants (Elephas maximus)
Authors: Glaeser Sharon S. , Edwards Katie L. , Wielebnowski Nadja , Brown Janine L.
Published: November 2020

Ensuring good health and welfare is an increasingly important consideration for conservation of endangered species and includes breeding of individuals managed under human care. Understanding how factors in the captive environment affect individual animal wellbeing can be aided by long-term monitoring of biological functioning. This study involved longitudinal assessments (4 to 28 years) of reproductive and adrenal hormones in zoo-housed female Asian elephants (Elephas maximus) (age range 4 to ~71 years) to elucidate patterns in adrenal glucocorticoid (GC) activity in association with reproductive and demographic factors, and examine individual response to major social changes. Concentrations of serum and urinary cortisol covaried more consistently with physiological changes (ovarian cycle phase, puberty, pregnancy, lactational anestrus, and age) than with social life events (births, deaths, and facility transfers). Cortisol fluctuated across the ovarian cycle with mean concentrations being higher in the follicular than in the luteal phase, and concentrations were highest in lactational anestrous compared to all other reproductive states. The elephants in this study exhibited substantial individuality in adrenal GC response to major social change, reinforcing the need to assess welfare on an individual basis and to consider factors influencing the impact of perceived stressors, such as social relationships, social support, temperament, and life history. Outcomes from this study deepen our understanding of Asian elephant physiology and highlight the importance of taking intrinsic patterns of hormone secretion into account when evaluating the impact of external factors. Finally, a better understanding of the impact of social change and resiliency in response to real and perceived stressors allows us to improve social management to enhance welfare in both captive settings and free-ranging environments.
Assessment of knowledge, attitude and practice on tuberculosis among teacher trainees of Samtse College of Education, Bhutan
Authors: Dorji Thinley , Tshering Tandin , Wangdi Kinley
Published: November 2020

Background

Tuberculosis (TB) is a major public health problem in Bhutan despite the implementation of directly observed treatment short-course since 1997. This study aimed to assess the knowledge, attitude and practice on TB among the teacher trainees of Samtse College of Education.

Methodology

A cross-sectional study was conducted among the teacher trainees of Samtse College of Education. A standardized pretested questionnaire was distributed and self-administered. The participants were selected randomly using randomization. The data was entered in Epi-data 4.4.2.1 and analysed using STATA version 13. A score of 1 point for a correct answer and 0 for wrong/don’t know answer was given. The knowledge, attitude and practice score were divided into good and poor based on 50% cut off. Logistic regression was used for the analysis to identify the significant covariates.

Results

A total of 420 trainees responded to the survey questionnaire. The average knowledge score on TB was 10.7 (Range = 0–21). Two hundred and forty respondents (58.6%) had low knowledge (mean score 7.8±2.5) on TB. Cough, chest pain and weight loss were correctly reported as the symptoms of TB by 306 (72.9%), 187(44.5%) and 187 (44.5%) participants. Eighty-nine-point five percent (376) of participants reported coughing as the main route of TB transmission and 85% (357) of the participants said that it could be prevented by covering the mouth while coughing. In multivariable analysis; the trainees in the junior years of college had good knowledge of TB compared with the senior years (adjusted odds ratio [AOR] 2.02; 95% confidence interval [CI] 1.18–3.5; p-value 0.011). Respondents previously treated for TB were more likely to have good knowledge on TB compared to those who never had TB in the past (AOR 2.39; 95% CI 1.07–5.31; p-value 0.033). The majority (93%) of respondents had a good attitude towards TB cases. Female trainees were 2.4 (95% CI 1.02–5.62; p-value 0.045) times more likely than male trainees to have a positive attitude towards TB. Eighty-eight percent of the respondents reported that they would visit the hospital if they had TB symptoms. The mean score for the practice on TB was 1.33±0.59 (Range:0–2).

Conclusion

In this study, the majority of the trainees had poor knowledge on TB, especially among the trainees in senior years of college and those who had never suffered from TB. The attitude towards TB was good especially among the female trainees. However, the overall practice was poor among the participants. Therefore, the Ministry of Health should collaborate with relevant stakeholders especially the Ministry of Education to incorporate topics on TB in the syllabus of students and colleges to create awareness on it.
Beyond the peak: A deterministic compartment model for exploring the Covid-19 evolution in Italy
Authors: Romano Silvio , Fierro Annalisa , Liccardo Antonella
Published: November 2020

Novel Covid-19 has had a huge impact on the world’s population since December 2019. The very rapid spreading of the virus worldwide, with its heavy toll of death and overload of the healthcare systems, induced the scientific community to focus on understanding, monitoring and foreseeing the epidemic evolution, weighing up the impact of different containment measures. An immense literature was produced in few months. Many papers were focused on predicting the peak features through a variety of different models. In the present paper, combining the surveillance data-set with data on mobility and testing, we develop a deterministic compartment model aimed at performing a retrospective analysis to understand the main modifications occurred to the characteristic parameters that regulate the epidemic spreading. We find that, besides self-protective behaviors, a reduction of susceptibility should have occurred in order to explain the fast descent of the epidemic after the peak. A sensitivity analysis of the basic reproduction number, in response to variations of the epidemiological parameters that can be influenced by policy-makers, shows the primary importance of a rigid isolation procedure for the diagnosed cases, combined with an intensive effort in performing extended testing campaigns. Future scenarios depend on the ability to protect the population from the injection of new cases from abroad, and to pursue in applying rigid self-protective measures.
Side by Side by Plutarch
Authors: Titchener Frances B.
Published: November 2020

Like many authors of his time, Plutarch associated specific characteristics and vocabulary with barbarians, notably superstition, great numbers, tremendous wealth, and the like. When he uses this language to describe non-barbarians, he is able to import a subtle negativity to his undertaking without distracting from his main narrative. The Life of Nicias furnishes a useful case study.

La educación culturalmente relevante: un modelo pedagógico para los estudiantes de origen cultural diverso. concepto, posibilidades y limitaciones
Authors: Rodríguez-Izquierdo Rosa M. , González-Faraco Juan Carlos
Published: November 2020

Este artículo presenta un estudio de la amplia producción científica sobre la Educación Culturalmente Relevante (ECR), un modelo pedagógico que pretende potenciar significativamente el éxito de los estudiantes culturalmente diversos. Este modelo, de origen norteamericano, es prácticamente desconocido en España. De ahí que las aportaciones de este trabajo puedan considerarse una verdadera novedad. Su objetivo es doble: profundizar en el conocimiento de la ECR, cuya eficacia avalan numerosas investigaciones empíricas, y valorar su traslación a nuestro contexto, en el que los alumnos de origen inmigrante suelen tener un rendimiento académico promedio más bajo que el de sus pares. Mediante el análisis de la literatura más importante sobre la ERC, se ha podido: 1, establecer las características teóricas más importantes de este modelo pedagógico, en relación con los de otros enfoques concomitantes y complementarios; 2, estimar su impacto en la mejora del rendimiento del alumnado culturalmente diverso; y 3, determinar sus posibilidades y limitaciones de traslación a nuestro contexto. Los resultados de este trabajo ponen de manifiesto la gran potencialidad de la ECR en la mejora de los procesos de aprendizaje de los estudiantes culturalmente diversos. Por otro lado, se subraya la importancia de la formación inicial y permanente del profesorado en el desarrollo de este modelo educativo, además de sus valiosas orientaciones para la investigación pedagógica y la praxis docente.
Líneas de acción y principios para la incorporación del aprendizaje-servicio en el ámbito local. Trabajo en red en el territorio
Authors: Bär Kwast Brenda , Campo Cano Laura , Rubio Serrano Laura
Published: November 2020

El presente artículo tiene como objetivo aportar algunas reflexiones acerca de la potencialidad del aprendizaje-servicio desde un punto de vista territorial. La construcción de apuestas educativas en el ámbito local a través del aprendizaje-servicio permite superar el desarrollo de experiencias concretas y aisladas y avanzar hacia la construcción de redes educativas que tienen un horizonte de bien común. Los aportes en este sentido parten de una investigación experiencial de corte cualitativo que ha combinado el análisis documental de diferentes experiencias anteriores y el proceso de investigación-acción realizado en tres territorios catalanes (Barcelona, Sant Cugat y Puig-Reig). En este texto se exponen las principales líneas de acción a desarrollar desde la perspectiva de facilitación y/o coordinación en el proceso de implementar el aprendizaje-servicio a nivel territorial: aproximación al territorio, diagnóstico compartido; generación de proyectos; y comunicación de la apuesta territorial. La reflexión acerca de este proceso subraya que todas ellas se sustentan en base a principios como la apertura, el reconocimiento, la coherencia y la sostenibilidad, entre otros. Asimismo, el trabajo también apunta algunas reflexiones acerca de la agencia educativa por parte de otros agentes del territorio, más allá de los centros educativos, y el fortalecimiento del trabajo en red para generar territorios más educadores.
Prolactin gene polymorphisms and associations with reproductive traits in Indonesian local ducks
Authors: Purwantini Dattadewi , Santosa R. Singgih Sugeng , Santosa Setya Agus , Susanto Agus , Candrasari Dewi Puspita , Ismoyowati Ismoyowati
Published: November 2020

Background and Aim: Reproductive traits play an important role in population increases and the egg production (EP) abilities of Indonesian local ducks (ILD). The prolactin (PRL) gene is a single chain polypeptide hormone belonging to a family of growth hormone genes that are mainly synthesized in the anterior pituitary gland in all vertebrates. It has a significant effect on reproductive traits and EP. Single nucleotide polymorphisms (SNPs) present in PRL are a useful molecular marker for EP. This study aimed to identify the PRL polymorphisms based on these SNPs and to uncover the associations with reproductive traits in ILD. Materials and Methods: A total of 280 ILDs consisting of Tegal and Magelang (F0) ducks and their reciprocal crosses, namely, Gallang (F1) and Maggal (F1), were maintained and specific variables were recorded, that is, age at first egg, body weight at first egg, first egg weight, and EP, for 90 days. Allele and genotype frequencies were used to determine the Hardy- Weinberg (H-W) equilibrium. The association between the SNP genotypes of PRL and reproductive traits was analyzed using one-way analysis of variance, following the GLM procedure of SAS. The genotypic effects on the reproductive traits were determined using regression analysis. Results: This study successfully amplified a polymerase chain reaction product of 190 bp, which was used to identify the SNP. Results indicated that PRL in ILDs is polymorphic. A SNP was found at position 164 nt (c.164G >A), consisting of three different genotypes, namely, GG, GA, and AA. The genotypes of Tegal and Magelang (F0), and Gallang (F1) populations were not in H-W equilibrium. The Maggal population (F1) was in H-W equilibrium. Significant associations were detected between the genotypes and EP in all ILDs (p<0.01), following a regression line of y=2.337x+64.605, with a determination coefficient of 0.0188 (r=0.14). Conclusion: PRL can be recommended as a candidate gene for reproductive traits in ILD, especially EP.

Published: November 2020

This study investigates the perceptions of teaching competency in multicultural classrooms held by 421 teachers at 16 schools in Hong Kong. The aims of the study are (a) to use confirmatory factor analysis to validate a culturally appropriate version of the Multicultural Teaching Competency Scale (MTCS), (b) to assess three types of multicultural-teaching competency, and (c) to provide recommendations for teacher-education institutes and policy makers on developing effective training in multicultural education. The results indicate that a tripartite model assessing skills, knowledge, and relationships, the core features of multicultural-teaching competency as assessed by the MTCS from a Hong Kong sample. The teachers all identified multicultural-teaching relationships as the most important component of multicultural-teaching competency. Future researchers should examine the concurrent validity of the MTCS and the cultural contexts of multicultural-teaching relationships. Recommendations are also made for incorporating the Confucian beliefs of fairness, justice, and equity into multicultural classroom.

of high-level security and no intermediary transactions. Although the requirements of land registry systems vary by country, common to all of them are the eye-catching advantages and conveniences that a blockchain-based system brings. We examined the process used in Turkey, which consists
of eight steps, identified the participants of the system, and generated a blockchain-based land registry system for Turkey. This article explains that proposed blockchain-based land registry system, configured for the local requirements of Turkey.
«Más» y «más» con Cristo. Cristología y santidad a la luz de «Gaudete et exsultate»
Authors: Gil Canto Salvador
Published: November 2020

El Concilio Vaticano II presentó en el capítulo V de la constitución dogmática Lumen gentium la llamada universal a la santidad de todos los miembros del pueblo de Dios. El papa Francisco, en la exhortación apostólica Gaudete et exsultate, nos ha recordado la validez y la necesidad de acoger de nuevo esa llamada a ser santos en el contexto eclesial y cultural de nuestros días. El presente artículo reflexiona sobre los elementos más destacados del contenido de la exhortación con el objeto de esclarecer el hondo significado de esta llamada a la santidad; profundiza en la dimensión cristológica que expone el documento, así como en la relación que existe entre el misterio de Cristo y la vocación a la santidad. Siendo la llamada a la santidad un tema teológico de primer orden, esta debe inspirarse en quién es «el Santo de Dios» (Jn 6,69) para que en el encuentro personal con Cristo se vislumbre el modelo de santidad al que estamos llamados. El dinamismo de la santidad reclama la llamada y el encuentro con Cristo para configurar la existencia cristiana según la forma Christi. Sin Cristo no hay santidad, sin una Iglesia santa no habrá anuncio misionero ni evangelización.

The COVID-19 Pandemic Exposes Fatal Health Inequities
Authors: Turshen Meredeth , Thébaud-Mony Annie
Published: November 2020

As stated in the United Nations Universal Declaration of Human Rights, health is a fundamental human right. However, we find ourselves in the midst of the COVID-19 pandemic with a shortage of both human and material health resources, most of which must be sourced from the private sector. Some of the wealthiest countries—France, Italy, Spain, the United Kingdom, and the United States—have proved unable to respond rapidly. The evolution of public health over the past four decades, during which government health policies have reduced health services to commodities and objects of speculative investment, has led to the current crisis.

The Mexican and Latino Question: What Is to Be Done?
Authors: Armbruster-Sandoval Ralph
Published: November 2020

In his book Chicano Communists and the Struggle for Social Justice, Enrique M. Buelna examines the life of Ralph Cuarón, a Mexican-American or Chicano seaman, furniture maker, father, husband, and lifelong activist who joined the Communist Party at age 19 during the Second World War. The Communist Party, however, largely ignored Mexican workers and local members were not pleased with his organizing of that segment of the working class. In the early twenty-first century, the Mexican question remained, although it became known as the "Latino question" after considerable immigration from Central America in the 1980s and '90s. In their book The Latino Question: Politics, Labouring Classes, and the Next Left, Armando Ibarra, Alfredo Carlos, and Rodolfo D. Torres deconstruct the word Latino, arguing that it homogenizes an extremely diverse population.
A Meta-Synthesis Study of Research About Mathematic Textbooks
Authors: Gökçek Tuba , Çelik Sedef
Published: November 2020

This research aimed to investigate studies examining mathematics textbooks in depth. To this end, specific keywords and criteria were entered into Google’s advanced search engine and the Council of Higher Education national thesis center to obtain articles and theses related to mathematics textbooks. The research investigated a total of 114 studies on mathematics textbooks published between 2005 and 2019. The data obtained were firstly subject to a descriptive analysis. A meta-synthesis method was then used to evaluate the studies included in this research. To analyze the objectives of the studies included in this research, we used the theoretical framework developed by Fan, Zhu and Miao (2013) to create an original classification. Results showed that studies examining opinions on mathematics textbooks (41.00%) were less than studies analyzing mathematics textbook (59.00%). Moreover, surveys were found to be the most frequentlyy used data collection tool in studies collecting opinions on mathematics textbooks, with teachers being the most commonly used participants subject to this data collection method. Additionally, the meta-synthesis analysis indicated that studies analyzing mathematics textbooks generally focused on topics specific to mathematics and on a specific section of a textbook (e.g. activities, problems) whereas those investigating opinions on mathematics textbooks concentrated on studies emphasizing the features of mathematical textbooks and the role of textbooks in learning-teaching.
The Wave Heights Distribution of Random Wave Based on Ocean Basin
Authors: Firdaus Nurman , Ali Baharuddin , Nasir Mochammad , Muryadin M
Published: November 2020

The wave height parameter in ocean waves is one of the important information for a marine structure design. The present paper investigates the results of wave heights distribution from laboratory-generated for single sea state. Data of the random wave time series collected at the ocean basin are analyzed using the wave spectrum and compared with the theoretical spectrum in this study. The random wave data is varied with four sea states consisting of sea states 3, 4, 5 and 6 obtained from laboratory measurements. The parameter conditions of generated sea waves are represented by a value of significant wave height and wave peak period in the range of sea states. The individual wave heights data in each sea state are presented in the form of exceedance probability distribution and the predictions using a linear model. This study aims to estimate the wave heights distribution using the Rayleigh and Weibull distribution model. Furthermore, the accuracy of the wave heights distribution data's prediction results in each sea state has been compared and examined for both models. The applied linear models indicate similar and reasonable estimations on the observed data trends.

Published: November 2020

As a green city, Surabaya had been developing a program of an environmentally friendly concept in almost all sectors. One of the developed sectors with this concept is the tourism area around the Kalimas river. Tour by riding a small passenger leisure boat is the most favorite recreational option. The leisure boat designs with environmentally friendly solar-powered concepts were developed, but regarding PV power and battery capacity determination, almost all designs are not optimal. This research is aimed to obtain the optimal PV power and battery capacity by calculating the number of PV panels and batteries with minimum cost. A Linear programming approach by Simplex method is applied in the optimization calculation. The results show that the number of the battery of the previous design can be reduced from 4 (four) units (20 kWh) becomes 3 (three) units (15 kWh) and the number of PV panels are still the same number with the previous one, i.e., 7 (seven) units (2,24 kW). The optimum system cost is around 264 million rupiahs, which means that the cost is reducing around 81 million rupiahs or 24%.

Digitalisierung als Informatisierung in der sozialen Arbeit?
Authors: Will-Zocholl Mascha , Hardering Friedericke
Published: November 2020

Aktuell wird die Digitalisierung als Megatrend des Wandels der Arbeitswelt thematisiert. Dabei greift der alleinige Fokus auf die Digitalisierung als Treiber und Auslöser aktueller Veränderungen zu kurz. Gerade im öffentlichen Sektor sind die Triebkräfte der anhaltenden Reorganisation in der Einführung des New Public Management (NPM) sowie der Sozial- und Gesundheitsreformen zu sehen. Versteht man diese Entwicklungen als Teil eines soziohistorischen Prozesses der Informatisierung, zeigt sich, dass die Diskussion um Digitalisierung der sozialen Arbeit neue Schlaglichter auf eine bekannte Debatte wirft, nämlich auf Tendenzen der Ökonomisierung, Bürokratisierung und Standardisierung von Arbeit. Der vorliegende Beitrag nimmt Bezug auf diese Entwicklungen und fragt danach, wie Führungskräfte in der sozialen Arbeit ihre Arbeit wahrnehmen, inwieweit sie Prozesse der Informatisierung und Digitalisierung als Chance oder Risiko sehen. In der Empirie zeigt sich, dass aus Sicht der Beschäftigten die Arbeits- und Beschäftigungsbedingungen im Feld der sozialen Arbeit weniger von Digitalisierung als von Informatisierung geprägt sind. Erfahren werden die Veränderungen primär als Belastungszunahme und Bedrohung für das professionelle Selbstverständnis.
Modeling and parameter identification for real-time temperature controlled retinal laser therapies
Authors: Kleyman Viktoria , Gernandt Hannes , Worthmann Karl , Abbas Hossam S. , Brinkmann Ralf , Müller Matthias A.
Published: November 2020

Laser photocoagulation is a widely used treatment for a variety of retinal diseases. Temperature-controlled irradiation is a promising approach to enable uniform heating, reduce the risks of over- or undertreatment, and unburden the ophthalmologists from a time consuming manual power titration. In this paper, an approach is proposed for the development of models with different levels of detail, which serve as a basis for improved, more accurate observer and control designs. To this end, we employ a heat diffusion model and propose a suitable discretization and subsequent model reduction procedures. Since the absorption of the laser light can vary strongly at each irradiation site, a method for identifying the absorption coefficient is presented. To identify a parameter in a reduced order model, an optimal interpolatory projection method for parametric systems is used. In order to provide an online identification of the absorption coefficient, we prove and exploit monotonicity of the parameter influence.

Authors: Wankhade Megha M. , Chorage Suvarna S.
Published: November 2020

Objectives

The Electroencephalogram (EEG) signal is modified using the Motor Imagery (MI) and it is utilized for patients with high motor impairments. Hence, the direct relationship between the computer and brain is termed as an EEG-based brain-computer interface (BCI). The objective of this survey is to presents an analysis of the existing distinct BCIs based on EEG.

Methods

This survey provides a detailed review of more than 60 research papers presenting the BCI-based EEG, like motor imagery-based techniques, spatial filtering-based techniques, Steady-State Visual Evoked Potential (SSVEP)-based techniques, machine learning-based techniques, Event-Related Potential (ERP)-based techniques, and online EEG-based techniques. Subsequently, the research gaps and issues of several EEG-based BCI systems are adopted to help the researchers for better future scope.

Results

Couples with infertility issues have been assisted byin vitrofertilization reproduction technologies with high success rates of 50-80%. However, complications associated with ovarian stimulation remain, such as ovarian hyperstimulation. Oocyte quality is a significant factor impacting the outcome ofin vitrofertilization procedures, but other processes are also critical for fertilization success. Increasing evidence points to aberrant inflammation as one of these critical processes reflected in molecular changes, including glycosylation of proteins. Here we report results from a MALDI-TOF-MS-based glycomic profiling of the total IgG and total proteome N-glycomes isolated from the follicular fluid obtained from patients undergoing fertilization through either (1) assisted reproduction by modified natural cycle or (2) controlled ovarian stimulation (GnRH antagonist, GnRH Ant) protocols. Significant inflammatory-related differences between analyzed N-glycomes were observed from samples and correlated with the ovarian stimulation protocol used in patients.
Crosslinguistic influence in development of reference realization: A comparison of foreign language learners and heritage language learners
Authors: Wu Shu-Ling
Published: November 2020

Recent developments in the study of crosslinguistic influence have started to account for how the dynamic interaction between language and cognition influences transfer phenomena. This study examined the acquisition and use of referring expressions in narratives produced by 80 English-dominant learners of Chinese representing two proficiency levels (Low vs. High) and two linguistic backgrounds (Foreign Language vs. Heritage Language), as compared to two baseline groups of 40 Chinese native speakers (NSs) and 40 English NSs. Results showed that, while heritage language learners (HLLs) demonstrated a more idiomatic use of referential forms to introduce new characters and maintain reference to them than did foreign language learners (FLLs) at the same low-proficiency level, the advantage of early language exposure diminished at the high-proficiency level when HLLs were compared to High FLLs who had prolonged in-country experience. Meanwhile, three types of production errors persisted, including (i) failing to use definite reference when obligatory for simple bare nouns, (ii) struggling to supply item-specific classifiers, and (iii) avoidance of zero anaphora, when discourse coherence would prefer such a strategy. All three of these features involve the restructuring of L1 preferences to accommodate L2-specific patterns due to L1-L2 typological differences.

Published: November 2020

Objectives

Monoclonal immunoglobulins can cause interference in many laboratory analyses. During a 4 month period we observed seven patients with monoclonal disease and falsely extremely elevated 25-hydroxyvitamin D (25(OH)D) results above 160 ng/mL (>400 nmol/L) measured using an immunoassay from Abbott Diagnostics. Based on these findings, we studied the occurrence of falsely elevated 25(OH)D in samples with paraproteins and investigated possible mechanisms of the observed interference.

Methods

25(OH)D was analyzed using the Architect i2000 platform from Abbott Diagnostics and a higher order method, liquid chromatography-mass spectrometry (LC-MS/MS), in serum samples from 50 patients with known monoclonal disease. Patients with falsely elevated 25(OH)D were included in further studies to elucidate the cause of interference. Spuriously elevated results were in addition analyzed on two alternative platforms (Siemens and Roche).

Results

Falsely elevated 25(OH)D levels were present in eight patients on the Abbott analyzer and one on the Siemens platform. Results from Roche were comparable with LC-MS/MS. Additional investigations excluded elevated concentrations of rheumatoid factor and heterophilic antibodies as the cause of interference in the Abbott assay.

Conclusions

Laboratories should be aware of the risk of falsely elevated 25(OH)D in samples run on the Architect analyzer from patients with monoclonal disease. Highly elevated vitamin D results should be diluted and if the dilution is non-linear, rerun by a different method, preferably LC-MS/MS. In patients with spuriously elevated 25(OH)D without known monoclonal disease, the laboratory should consider requesting protein electrophoresis to exclude paraprotein interference.
A promising naphthoquinone [8-hydroxy-2-(2-thienylcarbonyl)naphtho[2,3-b]thiophene-4,9-dione] exerts anti-colorectal cancer activity through ferroptosis and inhibition of MAPK signaling pathway based on RNA sequencing

Published: November 2020

Naphthoquinones are naturally occurring metabolites with recognized anti-cancer potential but limited clinical application. This study investigated the molecular mechanism of 8-hydroxy-2-(2-thenoyl)naphtho[2,3-b]thiophene-4,9-dione (1), a new candidate for colorectal cancer (CRC) treatment, using different experimental settings: MTT, clonogenic, wound healing, and cell cycle assays; as well as RNA sequencing. Naphthoquinone 1 selectively reduced the viability and migration of HT-29 cells by G2/M arrest and changes in their transcriptome signature with significant effect on cellular survival, proliferation, angiogenesis, response to interferon, oxidative stress, and immune response. Impact analysis identified ferroptosis and MAPK pathways as significantly affected. In summary, our results suggest that 1 induces the selective death of CRC cells by inducing oxidative stress, ferroptosis, and MAPK inhibition.

In this study, a numerical investigation tensile test using ANSYS on three different carbon and alloy sheets of steel: AISI 1030 medium carbon steel, AISI 1080 high carbon steel and high-strength low-alloy (HSLA) A606 steel, has been carried out. The influences of three different specimen geometries on the stress–strain curve were also investigated. Understanding the properties of these materials, such as stress–strain obtained from a tensile test, is important. Materials are subjected to forces or loads when in use, for example, steel in a ship’s hull experiences significant stresses and strains. In such situations, it is necessary to understand the characteristics of the material because grounding or collisions can occur, which deform the materials. The differences in stress and strain obtained from three specimens with different geometries and mesh sizes of 2.5, 5, 7.5, and 10 mm for all proposed steels, were observed. The results showed that the ultimate tensile strength was always lower in specimen 2 compared to the other specimens. Furthermore, the highest von Mises stress and strain contour was located in the midsection of specimens 1 and 3 in all of the proposed materials.
Enhancement of barrier and anti-corrosive performance of zinc-rich epoxy coatings using nano-silica/graphene oxide hybrid

Published: November 2020

This study reports a facile method to prepare silica-coated graphene oxide nanoflakes (SiO2–GO). Results of X-ray diffraction analysis, Raman spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy and atomic force microscopy reveal that silica was successfully coated on the GO flakes. The effect of SiO2–GO nanosheets on the corrosion protection and barrier performance of the epoxy coating was investigated in this work. Results indicate that the mechanical properties of all coatings added with GO and SiO2–GO were significantly improved. Furthermore, electrochemical impedance and Tafer polarisation curves showed that added 0.5 wt% SiO2–GO nanoflakes into zinc-rich epoxy coating could greatly improve the anti-corrosion performance of the sample, and the corrosion protection efficiency increased from 67.01 to 99.58%.
Nonlinear trending of corrosion of high nickel alloys in extended marine and atmospheric exposures
Authors: Melchers Robert E.
Published: November 2020

The relatively limited data for the corrosion and pitting of high nickel alloys are reviewed herein and time-dependent trends developed for exposures in marine and atmospheric environments. Data sets for average or ‘uniform’ corrosion losses that are sufficiently extensive show topological consistency with the bimodal functional model previously observed for steels and various copper-nickel and aluminum alloys. Trends for localized corrosion (pit or crevice depth) plateau after earlier rapid growth over several years. The present observations add support to the concept that there is a change in corrosion behavior with extended temporal exposure and that this is generally consistent for many alloys. They also reinforce that shorter-term observations of maximum corrosion or pit depth usually is unsuited for extrapolation to, and prediction of, longer-term corrosion as typically important for practical infrastructure applications.
