The DevTox Germ Layer Reporter Platform: An Assay Adaptation of the Human Pluripotent Stem Cell Test
Authors: Gamble John T. , Hopperstad Kristen , Deisenroth Chad
Published: July 2022

Environmental chemical exposures are a contributing factor to birth defects affecting infant morbidity and mortality. The USA EPA is committed to developing new approach methods (NAMs) to detect chemical risks to susceptible populations, including pregnant women. NAM-based coverage for cellular mechanisms associated with early human development could enhance identification of potential developmental toxicants (DevTox) for new and existing data-poor chemicals. The human pluripotent stem cell test (hPST) is an in vitro test method for rapidly identifying potential human developmental toxicants that employs directed differentiation of embryonic stem cells to measure reductions in SOX17 biomarker expression and nuclear localization. The objective of this study was to expand on the hPST principles to develop a model platform (DevTox GLR) that utilizes the transgenic RUES2-GLR cell line expressing fluorescent reporter fusion protein biomarkers for SOX17 (endoderm marker), BRA (mesoderm marker), and SOX2 (ectoderm and pluripotency marker). Initial assay adaption to definitive endoderm (DevTox GLR-Endo) was performed to emulate the hPST SOX17 endpoint and enable comparative evaluation of concordant chemical effects. Assay duration was reduced to two days and screening throughput scaled to 384-well format for enhanced speed and efficiency. Assay performance for 66 chemicals derived from reference and training set data resulted in a balanced accuracy of 72% (79% sensitivity and 65% specificity). The DevTox GLR-Endo assay demonstrates successful adaptation of the hPST concept with increased throughput, shorter assay duration, and minimal endpoint processing. The DevTox GLR model platform expands the in vitro NAM toolbox to rapidly identify potential developmental hazards and mechanistically characterize toxicant effects on pathways and processes associated with early human development.
Vegetative Insecticidal Protein Vip3Aa Is Transported via Membrane Vesicles in Bacillus thuringiensis BMB171

Published: July 2022

Vegetative insecticidal protein Vip3Aa, secreted by many Bacillus thuringiensis (Bt) strains during the vegetative growth stage, represents the second-generation insecticidal toxin. In recent years, significant progress has been made on its structure and action mechanism. However, how it is translocated across the cytoplasmic membrane into the environment remains a mystery. This work demonstrates that Vip3Aa is not secreted by the General Secretion (Sec) System. To reveal the secretory pathway of Vip3A, we purified the membrane vesicles (MVs) of B. thuringiensis BMB171 and observed by TEM. The size of MVs was determined by the dynamic light scattering method, and their diameter was approximately 40–200 nm, which is consistent with the vesicles in Gram-negative bacteria. Moreover, Vip3A could be detected in the purified MVs by Western blot, and immunoelectron microscopy reveals Vip3A antibody-coated gold particles located in the MVs. After deleting its signal peptide, chitinase B (ChiB) failed to be secreted. However, the recombinant ChiB, whose signal peptide was substituted with the N-terminal 39 amino acids from Vip3A, was secreted successfully through MVs. Thus, this sequence is proposed as the signal region responsible for vesicle transport. Together, our results revealed for the first time that Vip3Aa is transported to the medium via MVs.

Published: July 2022

Arctic regions are ecologically significant for the environmental persistence and geographic dissemination of influenza A viruses (IAVs) by avian hosts and other wildlife species. Data describing the epidemiology and ecology of IAVs among wildlife in the arctic are less frequently published compared to southern temperate regions, where prevalence and subtype diversity are more routinely documented. Following PRISMA guidelines, this systematic review addresses this gap by describing the prevalence, spatiotemporal distribution, and ecological characteristics of IAVs detected among wildlife and the environment in this understudied region of the globe. The literature search was performed in PubMed and Google Scholar using a set of pre-defined search terms to identify publications reporting on IAVs in Arctic regions between 1978 and February 2022. A total of 2125 articles were initially screened, 267 were assessed for eligibility, and 71 articles met inclusion criteria. IAVs have been detected in multiple wildlife species in all Arctic regions, including seabirds, shorebirds, waterfowl, seals, sea lions, whales, and terrestrial mammals, and in the environment. Isolates from wild birds comprise the majority of documented viruses derived from wildlife; however, among all animals and environmental matrices, 26 unique low and highly pathogenic subtypes have been characterized in the scientific literature from Arctic regions. Pooled prevalence across studies indicates 4.23% for wild birds, 3.42% among tested environmental matrices, and seroprevalences of 9.29% and 1.69% among marine and terrestrial mammals, respectively. Surveillance data are geographically biased, with most data from the Alaskan Arctic and many fewer reports from the Russian, Canadian, North Atlantic, and Western European Arctic. We highlight multiple important aspects of wildlife host, pathogen, and environmental ecology of IAVs in Arctic regions, including the role of avian migration and breeding cycles for the global spread of IAVs, evidence of inter-species and inter-continental reassortment at high latitudes, and how climate change-driven ecosystem shifts, including changes in the seasonal availability and distribution of dietary resources, have the potential to alter host–pathogen–environment dynamics in Arctic regions. We conclude by identifying gaps in knowledge and propose priorities for future research.

Published: July 2022

Since countries commenced COVID-19 vaccination around the world, many vaccine-related adverse effects have been reported. Among them, short-term memory loss with autoimmune encephalitis (AE) was reported as a rare adverse effect. Since case numbers are limited, this brief report may draw the attention of the medical community to this uncommon adverse effect and serve as a reference for future vaccine improvement. However, given the high risk of adverse outcomes when infected with SARS-CoV-2 and the clearly favorable safety/tolerability profile of existing vaccines, vaccination is still recommended.

Published: July 2022

Healthcare workers (HCWs) are one of the most vulnerable groups for contracting COVID-19 and dying as a result of it. Over 10,000 HCWs in Africa have been infected with COVID-19, according to the World Health Organization, making it a substantial occupational health threat for HCWs. To that end, Somalia’s Ministry of Health has ordered that all healthcare personnel obtain the COVID-19 vaccination to safeguard themselves and the community they serve. In this investigation, we aimed to assess the COVID-19 vaccination coverage and its associated factors among healthcare workers in Somalia. A cross-sectional study was employed to examine COVID-19 vaccination coverage among healthcare personnel in Somalia. The data were obtained via an online questionnaire supplied by Google forms between December 2021 and February 2022, where a total of 1281 healthcare workers from the various federal states of Somalia were recruited. A multinomial regression analysis was used to analyse the factors associated with COVID-19 vaccine uptake. Overall, 1281 HCWs participated (630 females, 651 males) with a mean age and standard deviation of 27.7 years ± 7.1. The overall vaccine coverage was 37.4%. Sex, age, the state of residency, education level, specialization, hospital COVID-19 policy, vaccine availability at the centre, COVID-19 treatment centre, and health facility level were the factors that influenced the COVID-19 vaccine uptake among health professionals in Somalia. Male healthcare employees were 2.2 times (odds ratio-OR = 2.2; confidence interval-CI: 1.70, 2.75, p < 0.001) more likely than female healthcare workers to be fully vaccinated. The survey discovered that the COVID-19 vaccine coverage among health professionals was quite low, with the major contributing factors being accessibility, security challenges and literary prowess. Additional efforts to enhance vaccination uptake are needed to improve the COVID-19 vaccination coverage.

Vaccination is an effective way in providing protection against COVID-19 infection and severe outcomes. However, vaccine resistance and hesitancy are a great concern among vulnerable populations including older adults who live alone or only with an older partner. This study examined their vaccination status and reasons and associated factors of vaccine resistance and hesitancy. A cross-sectional study was conducted among older adults living alone or only with an older partner in communities in Hong Kong. Participants were interviewed between October 2021 and February 2022. Logistic regression analyses were employed to examine factors associated with vaccine resistance and hesitancy. Of the 2109 included participants, the mean age was 79.3 years (SD 7.6), 1460 (69.2%) were female, 1334 (63.3%) lived alone, and 1621 (76.9%) were receiving social security support. The vaccine uptake, non-uptake (i.e., resistance), and hesitancy rates were 50.1%, 34.4%, and 15.5%, respectively. The top four reasons for vaccine resistance and hesitancy were “Not feeling in good health” (27%), “Worry about vaccine side effects” (18%), “Feeling no need” (10%), and “Lack of recommendation from doctors” (9%). Vaccine resistance and hesitancy was significantly associated with older age, living alone, more chronic conditions, fewer types of social media use, and lower self-rated health status. Similar associations can be observed in their separate analysis for vaccine resistance and vaccine hesitancy, and ever hospital admission over the past 6 months was additionally related to vaccine hesitancy. Older people who live alone or only with an older partner had a low vaccination rate. Poor health or worry about vaccine side effects were the most common reasons for their vaccine resistance and hesitancy. Actions are greatly needed to improve the uptake rate among this vulnerable population, especially those who were older, have poorer health, and use less social media.
The Big Potential of Small Particles: Lipid-Based Nanoparticles and Exosomes in Vaccination
Authors: Shimon Marina Ben , Shapira Shiran , Seni Jonathan , Arber Nadir
Published: July 2022

Some of the most significant medical achievements in recent history are the development of distinct and effective vaccines, and the improvement of the efficacy of previously existing ones, which have contributed to the eradication of many dangerous and life-threatening diseases. Immunization depends on the generation of a physiological memory response and protection against infection. It is therefore crucial that antigens are delivered in an efficient manner, to elicit a robust immune response. The recent approval of COVID-19 vaccines containing lipid nanoparticles encapsulating mRNA demonstrates the broad potential of lipid-based delivery systems. In light of this, the present review article summarizes currently synthesized lipid-based nanoparticles such as liposomes, lipid-nano particles, or cell-derived exosomes.

Published: July 2022

Varroa destructor is the most dangerous pest that poses a threat to honey bee survival. In recent years, increasingly worrying phenomena of drug resistance have occurred to various active ingredients of pharmaceutical formulations used to control this parasitosis. Determining the level of infestation is essential to preventing the inappropriate use and abuse of veterinary medicines, and to choose the most appropriate time for treatment. This comparative study investigates the sensitivity and diagnostic accuracy of two field techniques for diagnosing V. destructor infestations in hives. The EasyCheck device (Véto-pharma) was used in two of its application modes, namely, the sugar roll test and carbon dioxide (CO2) injection. The experiments were conducted on 15 samples of 300 bees each taken from the same frame and checked for the presence of mites using standard and modified field techniques in both uncaged and caged queen hive conditions. The results demonstrate that the sugar roll technique is significantly more effective and safer than CO2 injection, allowing for a higher accuracy in diagnosing a V. destructor infestation. Furthermore, the evaluation of mites present on bees in brood block conditions has proven to be particularly reliable. Considering the number of mites on the filter of the device as an additional step helps to implement the diagnostic accuracy of the CO2 injection technique, however, not achieving the efficacy results of the sugar roll.

Histological diagnosis of Canine Mammary Tumours (CMTs) provides the basis for proper treatment and follow-up. Nowadays, its accuracy is poorly understood and variable interpretation of histological criteria leads to a lack of standardisation and impossibility to compare studies. This study aimed to quantify the reproducibility of histological diagnosis and grading in CMTs. A blinded ring test on 36 CMTs was performed by 15 veterinary pathologists with different levels of education, after discussion of critical points on the Davis-Thompson Foundation Classification and providing consensus guidelines. Kappa statistics were used to compare the interobserver variability. The overall concordance rate of diagnostic interpretations of WP on identification of hyperplasia-dysplasia/benign/malignant lesions showed a substantial agreement (average k ranging from 0.66 to 0.82, with a k-combined of 0.76). Instead, outcomes on ICD-O-3.2 morphological code /diagnosis of histotype had only a moderate agreement (average k ranging from 0.44 and 0.64, with a k-combined of 0.54). The results demonstrated that standardised classification and consensus guidelines can produce moderate to substantial agreement; however, further efforts are needed to increase this agreement in distinguishing benign versus malignant lesions and in histological grading.
Making Room for Social Responsibility in Translator Training
Authors: İlmek Seda Taş
Published: July 2022

This study examines how the integration of social responsibility into translator training contributes to the learning and development of translation students. To this end, an action research design and an innovative situated learning project were implemented in an existing Bachelor's course in Translation and Interpreting. Students voluntarily performed two types of authentic translation tasks for a non-profit foundation and wrote project reports. The reports suggest that the integration of social responsibility into translator training raises the awareness of social responsibility among translation students and thus contributes to the improvement of their knowledge. It also has the potential to offer translation students a real experience and develop their translator competences. Therefore, this study proposes linking social responsibility with different learning environments in translator training because making room for social responsibility allows students to develop as socially responsible translators.
Invaders, Attackers and Destroyers: Trespassing-related Terms and Representations in Nigerian Newspaper Headlines
Authors: Igwebuike Ebuka Elias
Published: July 2022

Discourses on herding have focussed on the "exact" representations of the social actions of itinerant herders who clash with farmers while grazing on supposed cattle routes. Media coverage on the herdsmen-farmers conflict has deployed ideologically laden terms to represent herding as trespassing on farmlands and herders as foreigners and trespassers. Using van Leeuwen's Representation of Social Actions and Actors model and Martin and White's Appraisal Framework, this paper examines how different trespassing-related terms (i.e. invade, attack and destroy) were deployed in the Nigerian newspaper headlines to represent herders and their activities with a view to discussing the kinds of representations that were constructed of the nomads through the texts. Findings revealed that using transactive role allocations, nominalization, descriptivation, identification, aggregation and attitudinal lexicalization, these social actors were evaluated negatively as intruders, raiders, and destroyers. The negative othering underscores the general perception and suspicious treatment of nomads in their host farming communities.

The Effectiveness of Coleus Amboinicus l. Leaves Extract Solution for Grade II Laceration of the Perineal Tears in Postpartum Mothers
Authors: Pakpahan Sulastry , Sianturi Elly
Published: July 2022

Vaginal laceration (perineal tears) is one of the risks that often occurs in the process of vaginal delivery, because of the intense stretching and pressure in the birth canal when the mother pushes to deliver her baby, causing tears in the skin and muscle tissue around the birth canal. Treating birth perineal laceration is very important to accelerate healing and prevent infection of the birth canal and bladder in postpartum mothers. The leaves have a composition that can be used as an antimicrobial and antiseptic. This study aims to determine the effectiveness of a solution of extracts of the leaves of Coleus amboinicus on pain and healing of perineal lacerations in postpartum mothers. This type of quantitative research with experimental design. The research sample of postpartum mothers met the inclusion criteria, pain observation using the UPAT scale and wound healing using the REEDA scale, data analysis with the WMean Score. The results showed that postpartum pain decreased on the 5th day with an average of 1.97 (mild pain), and the healing time of perineal lacerations occurred on the 5th day, with a mean of 2.90 (good). Wax leaf extract solution is effective in reducing pain and healing time for second-degree perineal lacerations in postpartum mothers

La política social en relación al problema obrero y los sindicatos, a la luz de la Encíclica Rerum Novarum del papa León XIII
Authors: González González George
Published: July 2022

El presente artículo trata sobre la influencia de la encíclica Rerum Novarum del papa León XIII en la política social, documento este que, dada la inmutabilidad de la doctrina y moral cristianas, se erige como una carta abierta a los políticos de todos los tiempos. Se trata de un análisis científico que muestra la relación entre el magisterio petrino y la política social del siglo XIX, todo ello bajo los métodos cualitativo y morfológico, teniendo como referentes el arqueo de fuentes primarias y secundarias sobre el tema. Dicha investigación muestra cómo la obra de León XIII reaccionó ante el problema obrero, que constituyó uno de los campos en los que más fueron violados la dignidad y los derechos humanos. Asimismo, el Sumo Pontífice se presenta como un propulsor de la creación de sindicatos y asociaciones que dieron fuerza al gremio obrero, en tanto estos ya no actuaban de forma solipsista, sino en conjunto, lo que los hizo más fuertes.

Abstract. Bitcoin's value can fluctuate unpredictably over a short period of time as a result of its young, new economic value and a non-liquid market. The problem commonly faced by investors and traders is how to predict the movement of the value of Bitcoin electronic money in the future based on past data. Investors and traders only see movements based on movements in the value of world currencies and decide to buy / sell Bitcoin intuitively, so they often make wrong buying / selling transactions. This error caused many investors and traders to lose a large amount. Losses that occur can be minimized by using an algorithm that can predict the movement of the value of Bitcoin electronic money. This study aims to identify and analyze data on the movement of electronic money values using the Moving Average (MA) forecasting algorithm. Bitcoin movement data tested for 5 years to test the accuracy of forecasting. The data collection process is taken from public data available on investing.com and meta trader 4 with the help of the C# programming language. The test results show that the correct percentage predicted in the Buy / buy technique is 62.86%, while for the selling technique in the same period it shows the percentage of correct predictions is only 25%.

Published: July 2022

The Faculty of Information Technology, Perbanas Institute, is still processing work assignments for students (read: KKP), as well as manual submissions for “the KKP” supervisors. To determine the supervisor, the Head of the Study Program is only supported by manually processed data. During guidance with the supervisor, both students and lecturers record the guidance material on paper so that it is at risk of being lost or scattered. In addition, the evaluation process for the Job Training Lecture activity is still written on paper, so that the assessment is not confidential. This paper presents the design of an information system to process the application for the Practical Work Lecture program and the determination of student supervisors. Applications developed using the Analytical Hierarchy Process (AHP) model and running in Web Base mode. The main feature of the application is in the form of a computerized name recommendation system for the internship supervisor.

Abstract. One of the challenges in the world of education is the application of increasingly advanced technological innovations. One example is the application of the updated printed management information system using augmented reality at the Open University. The printed teaching materials for the management information system require additional supplementation with augmented reality because there are so many images that require more detailed explanations. With the augmented reality-based supplement, it is hoped that it will be more useful to the readers of the printed teaching materials. This study adds augmented reality supplements to printed teaching materials for management information systems using the waterfall model. It aims to provide an explanation of the material that is not written in the printed teaching materials and provide more useful information than other printed teaching materials. The results show that the application runs well and is ready to be used by the user. This can be seen from the functional and non-functional tests that have been carried out. From functional testing the application can run on devices that have a camera of more than 3MP while from non-functional testing the application gets a score of 80.125, meaning that the application is acceptable and useful to users.
