Authors: Carvalho Luiz Paulo , Suzano José Antônio , Oliveira Jonice , Gasparini Isabela , Santoro Flavia Maria
Published: December 2021

There is no doubt about the relevance of Computing in Education (CE), especially after the COVID-19 pandemic. However, the more we deal with computational artifacts in Education, the more we will have to face ethical dilemmas and concerns behind the engineering of the educational artifact and its values and qualities. In the context of the Brazilian Symposium on Computers in Education (SBIE), this paper aims to answer the question: what is the panorama of the occurrence of ethical aspects in SBIE publications between 2011-2020? To answer this question, we followed the methodology of Systematic Literature Review. We analyze topics such as Informed Consent, Ethics Committee, technological domains, ethical principles, and research contexts.

Published: December 2021

Os Recursos Educacionais Abertos (REA) visam tornar o conhecimento mais livre e acessível para todos. É fundamental a disponibilização de repositórios que promovem a descoberta, o uso e a reutilização de REAs para que estes possam ser melhor utilizados. Diante disso, é relevante avaliar se, no Brasil, os Repositórios de REA (RREA) possuem qualidade para prestar apoio à educação básica. Neste artigo, realizamos uma análise comparativa entre RREA brasileiros voltados para o ensino básico. Forma selecionados repositórios segundo os seguintes critérios: serem nacionais, abrangentes e terem conteúdos voltados exclusiva ou majoritariamente ao ensino básico. Os repositórios selecionados foram avaliados com o uso de Indicadores de Qualidade. Apesar do grande número de RREA disponíveis, a pesquisa revelou um baixo número de RREA voltados ao ensino básico, especialmente os de alto rendimento, o que demonstra que ainda há um caminho a ser percorrido nessa área.

Published: December 2021

Jogos Sérios (JS) devem ser projetados com foco não apenas na reação, mas na avaliação do desempenho do aluno, o que tem sido negligenciado. Este trabalho visa desenvolver e avaliar o AvaliaJS, um modelo conceitual (que possui dois artefatos: modelo canvas e documento de projeto) para estruturar, orientar e apoiar o planejamento da concepção e execução da avaliação. Os artefatos foram aplicados a três jogos já prontos, como prova de conceito. A qualidade foi avaliada por seis especialistas em desenvolvimento e avaliação de JSs, por meio de um questionário. Os resultados apontam que o modelo pode auxiliar na documentação e desenvolvimento dos artefatos, coleta de dados e execução da avaliação.
To Vote or not to Vote?
Authors: Agbele Fortune
Published: December 2021

This book examines variations in voter turnout at the sub-national level during general elections. It employs a case study–mixed methods approach, combining quantitative and qualitative data to provide in-depth evidence for three systematically selected constituencies with varying levels of voter turnout. Findings from the study challenge the adequacy of the strict application of rational choice theory in providing a comprehensive understanding of why voter turnout might vary. The book furthermore advances a framework, that is, individual and collective-level utilities, expanding on the concept of utility to account for variations in voter turnouts. The book’s conclusions highlight the importance of local contexts in shaping voter behaviour and emphasises the primacy of local political dynamics when studying voter behaviour. Moreover, the book enriches our understanding of voter behaviour on the African continent, underscoring the need to adopt a multi-dimensional lens for the study of African politics.

Authors: Rezaei Azadeh , Shariati Abdolali , Molavynejad Shahram , Ghanbari Chah Anjiri Saeed
Published: December 2021

Background: One of the effective nursing measures for enhancing the quality of life (QOL) and adaptation of patients undergoing coronary artery bypass graft (CABG) is the use of Roy’s adaptation model (RAM). Objectives: This study aimed to determine the effect of a training program based on Roy’s adaptation model on the adaptation of patients undergoing CABG. Methods: This quasi-experimental study was performed on 60 patients admitted to the intensive care units (ICUs) of Imam Khomeini Hospital and Golestan Hospital in Ahvaz, southwest of Iran, in 2020. Patients were selected based on inclusion criteria and randomly assigned into intervention and control groups. A four-session training program based on RAM was held for the intervention group. Data were analyzed using SPSS ver. 22. Results: The mean scores of physiological, self-concept, role function, and independence and interdependence dimensions in the experimental group before the intervention were 48.76 (6.36), 23.76 (4.10), 19.60 (2.93), and 25.60 (3.54), respectively. After the intervention, the mean scores in the mentioned dimensions were 101.26 (5.23), 50.80 (3.82), 39.10 (4.15), and 25.47 (3.99), respectively, indicating an upward trend (P < 0.05). Also, the mean score of total adaptation before the intervention was 117.73 (12.00), which rose to 216.63 (7.88) after the intervention (P < 0.05). Conclusions: The results showed that RAM plays an important role in the adaptation of patients undergoing CABG surgery. Thus, this model can provide a suitable framework for examining and providing care for patients undergoing CABG in ICUs.

Published: December 2021

Background: Escherichia coli in the vagina includes several virulence factors in its genome mobile genetic elements and can facilitate colonization, mainly in immunosuppressed patients. Objectives: This work aimed to demonstrate that E. coli strains of vaginal origin isolated from dysplastic patients possess virulence and resistance genes Methods: This study included one hundred and five E. coli strains isolated from women with cervical dysplasia and vaginal infection. The strains were characterized by antimicrobial susceptibility. The Clermont algorithm performed the phylogenetic assignment. The structure of class 1 integrons was performed by identifying integrase (int1), the variable region, and qacEΔ1-sul1 genes. The variable region was amplified, sequenced, and analyzed. Enterobacterial repetitive intergenic consensus (ERIC) PCR and virus typing typed strains with identical genetic arrangements by detecting virulence genes related to cytotoxicity, adherence, and iron uptake. Results: Escherichia coli strains showed great resistance to β-lactams and quinolones, and phylogenetic assignment showed that the group A/C was highly predominant. Sixteen integrons were identified, with monogenic arrays represented by aadA1, dfrB4dfrA7, dfr2D, and dfrA17 cassettes. The prevalence of the biogenic arrays aadA1/dfrA1 and aadA5/dfrA17 was lower than that of blaOXA-1/aadA1. Concerning virulence genes, fimH, traT, and iutA were the most predominant. Conclusions: The high incidence of virulence and resistance factors in commensal and virulent strains of E. coli revealed potential tools in the pathogenesis of vaginal infection.

Published: December 2021

Background: In recent decades, reducing the size of the drug delivery systems along with precise control of the amount of drug pumped, has attracted the attention of many researchers. Objectives: The slow subcutaneous infusion of the deferoxamine in thalassemia major patients during day is of vital importance either for the drug effectiveness. However, this is difficult to achieve due to the large size of the conventional infusion pumps and their high weight. Therefore, size and weight reduction of the infusion pumps are very important issues that must be well addressed. Methods: A biomedical micropump for drug solution infusion to human body based on the magnetohydrodynamic (MHD) concept is and designed, and its performance experimentally is investigated in this research. The key challenge in the fabrication of the micropump is its size, weight, bubble generation, and high operating voltage. Results: The present design is well responded to these problems. The final design operates with a 1.2 v without any bubble generation, while its size and weight are 20 × 40 × 50 mm3 and 90 grams, respectively. The size of the micropump is about 1/3 size of conventional micropump, while its weight is half of them. Conclusions: Therefore, the newly designed micropump has the ability to inject the drug solution to thalassemia major patients with a sufficient infusion rate during the day without disturbing them, so it can increase their quality of life and increase their life expectancy.
Vagueness and Theory of Gaps
Authors: Hlouch Lukáš
Published: December 2021

This contribution is dedicated to the concept of gap (lacuna in Latin, Lücke in German), more precisely to the theory of gaps and its role in legal thought, particularly in the Czech Republic. The starting point to this analysis is the notion of vagueness. For the beginning, different meanings of vagueness shall be presented and explained. Then the focus shall be laid on the relation between the ‘theory of gaps’ and vagueness. Therefore main attention is paid to the theoretical distinctions between various types of legal gaps and their usage in the legal practice. As a conclusion I will try to resolve the question whether or not the notion of ‘gap’ shall apply for instances of vague terms (uncertainty) of normative text.

The aim of this paper is to analyze the body of crime and the punishments imposed according to C 9. 8. 5. The punishments will be examined both concerning their efficiency and compliance with modern approaches, such as individual and general prevention and repression, and non-discrimination.
Dr. Korbuly Pál, sudca Štátneho súdu v Bratislave
Authors: Neupauer František
Published: December 2021

The history of law indeed refers to persons handing down judgments and often offers interesting stories, such as the story of a judge working under various political regimes Dr. Pavel Korbuly (1906–1970). On May 4, 1934, Korbuly was appointed a single judge in criminal matters, after 1948 he became an instrument of justice under the communist regime and was one of the most active judges of the State Court in Bratislava. Prior to the Vienna Arbitration, he was a judge in the Czechoslovak Republic, then in Hungary, and after 1948 he was one of the judges who tried and sentenced victims of the communist regime (more than 500 people) in Slovakia. By the same communist regime, however, Korbuly was later prosecuted due to his active support of the anti-communist uprising in Hungary in 1956. Unlike others, he was one of the judges who had realized their responsibility for convicting the innocent and committed public repentance. From this perspective, his life story is unique in Central Europe as well as worldwide.
Poválečné perzekuce příslušníků armády a přijetí zákona na ochranu lidově demokratické republiky
Authors: Řepa Tomáš
Published: December 2021

After the end of the Second World War, Czechoslovakia was a country at a crossroads. The communists tried to take control of key institutions of the state, including the army. In doing so, a number of illegalities were committed. After the coup in February 1948, this was followed by the adoption of legislation by the already totalitarian state. A striking example was Law No. 231/1948 on the Protection of the People’s Democratic Republic, adopted in October 1948. On the basis of this law, many thousands of people were convicted for alleged anti-State acts.

Estonian Male Journalists’ Experiences with Abusive Online Communication
Authors: Riives Armas , Murumaa-Mengel Maria , Ivask Signe
Published: December 2021

Several studies have established that female journalists experience (sexual) harassment and online abuse considerably more than their male colleagues. Understandably, this has resulted in a gap in research – male journalists’ experiences with abusive online communication have not yet been thoroughly studied. This paper seeks to understand how abusive communication is contextualised and defined by male journalists in the context of hegemonic masculinity, and to explore which coping strategies are employed to overcome such experiences. From qualitative in-depth interviews with male journalists (n=15), we found that participants considered different forms of abusive online communication from readers/sources a normalised practice, “feedback” that one must just ignore or overcome. Experiences are interpreted predominantly in the frame of hegemonic (complicit) masculinity, but the results also indicate that shifts in these rigid norms are emerging and can be embraced when acknowledged and supported by surrounding structures.
Hoffmanigraptus n. gen., a new retiolitine (Graptolithina), an early member of the Plectograptus lineage from the Silurian of Baltica, Poland
Authors: KOZŁOWSKA Anna
Published: December 2021

Most upper Homerian and Ludfordian retiolitines have a tubarium with hexagonal meshes and a zigzag pattern in the middle part of their lateral walls, a shallow ancora umbrella, and a free nema. Hoffmanigraptus varsoviensis n. gen., n. sp. is described from isolated, three-dimensional material, from the upper part of the Colonograptus praedeubeli Biozone (upper Homerian, Silurian) of Poland, Baltica, and represents one of the earliest forms with this construction. This type of tubarium is represented by the upper Homerian Doliograptus Lenz & Kozłowska-Dawidziuk, 2002 and Spinograptus Bouček & Münch, 1952, differing from Hoffmanigraptus n. gen. mainly in larger proximal lateral orifices, pattern of clathrial lists on lateral walls, as well as size and shape of tubaria. Hoffmanigraptus n. gen. has a tubarium widening medially, tapering towards the distal end and forming a finite tubarium, with a possible three-vaned nematularium. Flattened specimens Plectograptus? ovatus Kozłowska, Lenz & Štorch, 2001 and Plectograptus? karlsteinensis Kozłowska, Lenz & Štorch, 2001, preserved on a rock surface from the Barrandian area are assigned to the new genus. They are of the same upper Homerian age, and show the main features of the new form. Hoffmanigraptus n. gen. is regarded as an early member of the Plectograptus clade.

Published: December 2021

Introduction Sleep is essential for performing cognitive function in humans. We have hypothesized that sleep fragmentation compared to sleep efficiency may have a negative impact on the working memory.

Material and Methods Twenty-eight healthy adults (18 males and 10 females; mean age 27.8±15.5 years) were enrolled in this study. We measured the total sleep time (TST), sleep efficiency, %stage wakefulness (W), %stage rapid eye movement (REM), %stage N1, %stage N2, %stage N3, wake after sleep onset (WASO), and arousal index using polysomnography. Working memory, executive function, and sustained attention of three domains of cognitive function were evaluated with the number of back task (N-back task), Wisconsin card sorting test (WCST), and continuous performance test-identical pairs (CPT-IP), respectively.

Results The percentage of correct answers on the 2-back task was significantly correlated with %stage REM, %stage N1, and %stage N2 (%stage REM: r=0.505, p=0.006; %stage N1: r=-0.637, p<0.001; %stage N2: r=0.670, p<0.001), and multiple regression analysis including the stepwise forward selection method revealed that %stage N2 was the most significant factor (%stage N2: β=0.670, p<0.001). The percentage of correct answers on the 2-back task was also significantly correlated with TST, sleep efficiency, WASO, and arousal index (TST: r=0.492, p=0.008; sleep efficiency: r=0.622, p<0.001; WASO: r=-0.721, p<0.001; arousal index: r=-0.656, p<0.001), and WASO was the significant factor (β=-2.086, p=0.007). The WCST category achievement and CPT-IP d-prime score were correlated with none of the sleep variables.

Conclusion Increased WASO and a decrease in %stage N2 were associated with worse working memory.
An easy maneuver to screen for moderate-to-severe obstructive sleep spnea: the Simmons Chin Press and Tongue Curl
Authors: Meskill Gerard Joseph , Kincheloe Kelly , Simmons Jerald Howard , Meskill Sarah Dennis
Published: December 2021

Objectives: To demonstrate that the Simmons chin press and tongue curl (SCPTC) correlates with diagnosis of moderate-to-severe obstructive sleep apnea (msOSA) by itself as well as irrespective of the presence of other associated features.

Material and Methods: A consecutive sample of 1,911 sleep studies performed on adult patients from 2/8/2017 to 3/5/2019 was analyzed. The SCPTC exam maneuver was performed on each patient, followed by home sleep apnea testing or in-laboratory polysomnography. The AASM hypopnea 1B 4% desaturation criteria were utilized for scoring to correlate results to existing literature on morbidity and mortality. A chi-squared using low and high SCPTC score was performed for the outcome of msOSA. Known significant predictors of OSA were dichotomized for comparison and a multiple logistic regression was performed.

Results: 1,708 patients qualified for inclusion: 902 males (52.8%) and 806 females (47.2%) with a mean age of 49.4 and a mean body mass index (BMI) of 28.6. A high SCPTC score correlated with an odds ratio (OR) of 2.49 (95% CI: 2.03-3.04, p<0.001) for msOSA. A multiple logistic regression analysis including other risk factors for msOSA demonstrated that high SCPTC scores had an odds ratio for msOSA of 1.77 (95% CI: 1.40-2.23; p<0.001).

Conclusion: The SCPTC is a reproducible physical exam feature that can be utilized by healthcare providers to screen for patients with msOSA.
Strain specific behavioral and physiological responses to constant light in male CBA/J and CBA/CaJ mice
Authors: Deane Hannah V , Concepcion Holly A , Gatewood Avery E , Quintana Janessa , Seggio Joseph A
Published: December 2021

Objective: Being visually impaired increases the likelihood of sleep disorders and altered behavior. This study investigated physiological and behavioral differences in two similar mice substrains when exposed to constant light (LL) - CBA/J with retinal degeneration and CBA/CaJ mice (no retinal degeneration).

Material and Methods: Male CBA/J and CBA/CaJ mice were placed into a 12:12 light:dark cycle or constant light (LL). Open field behavior, metabolic markers, and home-cage circadian activity were observed.

Results: CBA/CaJ mice have greater circadian period lengthening, increased weight gain, reduced glucose, and increased novelty-induced locomotor activity in LL, compared to CBA/J mice. LL reduced thyroid hormone and insulin in both substrains.

Discussion: While several baseline substrain differences were elucidated, CBA/CaJ mice were more effected by the exposure to LL than the blind CBA/J mice. These results illustrate that LL causes alterations in physiology and behavior and that circadian photoreceptivity might contribute to these effects.
What does your favourite colour say about your personality? Not much
Authors: Jonauskaite Domicele , Thalmayer Amber Gayle , Müller Lauriane , Mohr Christine
Published: December 2021

The claim that favourite colours reveal individuals’ personalities is popular in the media yet lacks scientific support. We assessed this claim in two stages. First, we catalogued claims from six popular websites, and matched them to key Big Six/HEXACO trait terms, ultimately identifying 11 specific, systematic, testable predictions (e.g., higher Extraversion among those who prefer red, orange, yellow, pink, or turquoise). Next, we tested these predictions in terms of the Big Six personality trait scores and reports of favourite and least favourite colours from 323 French-speaking participants. For every prediction (e.g., red-extraversion), we compared trait scores between participants who chose or did not choose the predicted colour using Welch’s t-tests. We failed to confirm any of the 11 predictions. Further exploratory analyses (MANOVA) revealed no associations between colour preferences and personality trait. Favourite colours appear unrelated to personality, failing to support the practical utility of colour-based personality assessment.

Published: December 2021

Background: Philanthropic donations are important funding sources in academic oncology but may be vulnerable to implicit or explicit biases toward women. However, the influence of gender on donations has not been assessed quantitatively. Methods: We queried a large academic cancer center’s development database for donations over 10 years to the sundry funds of medical and radiation oncologists. Types of donations and total amounts for medical oncologists and radiation oncologists hired prior to April 1, 2018 (allowing ≥2 years on faculty prior to query), were obtained. We also obtained publicly available data on physician/academic rank, gender, specialty, disease site, and Hirsch-index (h-index), a metric of productivity. Results: We identified 127 physicians: 64% men and 36% women. Median h-index was higher for men (31; range, 1–100) than women (17; range, 3–77; P=.003). Men were also more likely to have spent more time at the institution (median, 15 years; range, 2–43 years) than women (median, 12.5 years; range, 3–22 years; P=.025). Those receiving donations were significantly more likely to be men (70% vs 30%; P=.034). Men received significantly higher median amounts ($259,474; range, $0–$29,507,784) versus women ($37,485; range, $0–$7,483,726; P=.019). On multivariable analysis, only h-index and senior academic rank were associated with donation receipt, and only h-index with donation amount. Conclusions: We found significant gender disparities in receipt of philanthropic donations on unadjusted analyses. However, on multivariable analyses, only productivity and rank were significantly associated with donations, suggesting gender disparities in productivity and promotions may contribute to these differences.
Robótica para la inclusión educativa: una revisión sistemática
Authors: Rodrigo Parra Judit
Published: December 2021

La educación debe ser inclusiva y uno de los instrumentos de los que se puede servir es la robótica. Además, uno de los elementos de la robótica es la programación y para programar se aplica el pensamiento computacional. Por otra parte, para que la educación sea inclusiva se debe atender a la diversidad. Así, se procede a desarrollar una revisión sistemática sobre el uso de la robótica para la inclusión educativa. Las preguntas de investigación son: ¿La robótica educativa puede ser una estrategia de inclusión educativa?, ¿qué beneficios se obtienen con el uso de la robótica en la inclusión educativa? y ¿cómo es la formación de los docentes en relación con el uso de la robótica para la inclusión? Tras aplicar filtros siguiendo la declaración PRISMA han sido seleccionados 23 estudios pertenecientes a las bases de datos Scopus y WOS. Las conclusiones son que la robótica sí puede ser una estrategia de inclusión educativa. Además, se señalan numerosos beneficios de la misma, como el aumento de la motivación, la creatividad y la capacidad de trabajo en equipo y la mejora en habilidades sociales y comunicativas. En lo relativo a la formación docente en este ámbito se han obtenido pocos resultados, pues muy pocos estudios de la revisión sistemática tratan este tema. No obstante, se destaca que la mayoría de los docentes considera la robótica una herramienta útil para la inclusión educativa.

Education must be inclusive and one of the tools used to achieve this is robotics. In addition, one of the elements of robotics is programming and computational thinking is applied to program. On the other hand, to ensure that education is inclusive, there must be diversity. I proceed to develop a systematic review on the use of robotics for educational inclusion. The questions of this research are: Can educational robotics be a strategy for educational inclusion? What benefits are obtained with the use of robotics in educational inclusion? How is the training of teachers in relation to the use of robotics for inclusion? After applying filters following the PRISMA statement, 23 studies belonging to the Scopus and WOS databases have been selected. The conclusions are: educational robotics can indeed be a strategy for educational inclusion. In addition, numerous benefits are reported, such as increased motivation, creativity and teamwork skills, and improved social and communication skills. Few results have been obtained about teacher training in this área (very few studies in the systematic review address this issue). However, it is noted that most teachers consider robotics a useful tool for educational inclusion.
Satisfaction au travail et attachement à l’emploi des enseignants/es d’éducation physique : une contribution à l’analyse des conditions de travail en enseignement au Québec
Authors: Desbiens Jean-François , Larouche René
Published: December 2021

Les enseignants d’éducation physique et à la santé (ÉPS) disposent d’un faible statut qui les expose à de la dévalorisation et à de la marginalisation. Après un bref état de la situation de l’enseignement au Québec, l’attention est ensuite portée sur celle des enseignants en ÉPS. Un cadre conceptuel articulant les modèles de la satisfaction au travail et de l’attachement à l’emploi est ensuite proposé pour étudier la situation de ces enseignants au Québec. En conclusion de cette réflexion théorique, il est avancé qu’en période de pénurie d’enseignants, les organisations scolaires devraient s’inscrire dans une culture de gestion durable des ressources enseignantes.
Utilitarian attitude and norm in the discourse of Russian nationalists (on the material of the social network “VKontakte”)
Authors: Golikov Leonid Mikhailovich
Published: December 2021

Expressions with the predicative “expediently” manifest as a regular means of realization of modality of necessity, which is diverse in the semantic characteristics. The article aims to determine the type of the meaning of necessity and the nature of potentiality contained in such expressions in the discourse of Russian nationalists in the social network “VKontakte”. The article employs the methods semantic and pragmatic analysis. The author describes the predicative “expediently” as a modal operator of necessity, and the structure of the situation of necessity reflected by the expressions in the specified pragmatic conditions. The author reveals the semantic characteristics of combination of the utilitarian and deontic modalities that recognize such forms as the norm. It is established that expressions with the predicative “expediently” in the discourse of Russian nationalists manifest as the target norms and norms of operational preference. Such examples, due to their semantic and pragmatic characteristics, are the traditional method for realization of the speech act of appeal. The obtained results can be used in linguistic expertise, as they represent the significant diagnostic attributes of speech act of appeal in the pragmatic conditions of sociopolitical discourse. The scientific novelty is consists in the fact that this article is first to characterize the expressions with the predicative “expediently” as the forms of realization of meaning of the norm, which are recognized as the speech act of appeal in the discourse of Russian nationalists.

The purpose of this paper is to analyze the role of Posidonius as a source for Strabo. Both were Greek-speaking authors who lived under Roman rule, and both professed Stoic doctrine. Strabo made extensive use of Posidonian works to complete his own geographical ouvre, however, we will see that the conditioning factors derived from the different political necessities in which each lived would mark fundamental ideological and methodological differences.
Going minimal: An exploration of reduction as a design method
Authors: Redyantanu Bramasta Putra
Published: December 2021

The purpose of this paper is to reflectively explore minimalist architecture as an architecture that is driven by the reduction-based design method. The discussion aims to reframe the design processes and methods of minimalist architecture as informed by field observation. The phenomenon of applying a minimalist architectural approach has become a trend in small-scale housing in Indonesia lately. In the country, the small-scale residential design processes take place in different contexts and are faced with various limitations, from resources, budgets, land size, materials, and so on. The study will frame this discussion around exploring the reductive design method as a way of responding to these limitations. Informed by design strategies from the modern architecture movement, the study was conducted by observing reduction strategies in eight small-scale domestic design which was published and well-narrated in various media. The study findings demonstrate that the reduction does not only exist in the visual aspect of the design and construction process. It also exist in numerous other design elements, such as materials, forms, spaces, and ornamentation, as a strategic response towards the limitations of various resources.
Diverse mating phenotypes impact the spread of wtf meiotic drivers in Schizosaccharomyces pombe
Authors: López Hernández José Fabricio , Helston Rachel M , Lange Jeffrey J , Billmyre R Blake , Schaffner Samantha H , Eickbush Michael T , McCroskey Scott , Zanders Sarah E
Published: December 2021

Meiotic drivers are genetic elements that break Mendel’s law of segregation to be transmitted into more than half of the offspring produced by a heterozygote. The success of a driver relies on outcrossing (mating between individuals from distinct lineages) because drivers gain their advantage in heterozygotes. It is, therefore, curious that Schizosaccharomyces pombe, a species reported to rarely outcross, harbors many meiotic drivers. To address this paradox, we measured mating phenotypes in S. pombe natural isolates. We found that the propensity for cells from distinct clonal lineages to mate varies between natural isolates and can be affected both by cell density and by the available sexual partners. Additionally, we found that the observed levels of preferential mating between cells from the same clonal lineage can slow, but not prevent, the spread of a wtf meiotic driver in the absence of additional fitness costs linked to the driver. These analyses reveal parameters critical to understanding the evolution of S. pombe and help explain the success of meiotic drivers in this species.

Published: December 2021

Nature has evolved many supramolecular proteins assembled in certain, sometimes even seemingly oversophisticated, morphological manners. The rationale behind such evolutionary efforts is often poorly understood. Here, we provide atomic-resolution insights into how the dynamic building of a structurally complex enzyme with higher order symmetry offers amenability to intricate regulation. We have established the functional coupling between enzymatic activity and protein morphological states of glutamine synthetase (GS), an old multi-subunit enzyme essential for cellular nitrogen metabolism. Cryo-EM structure determination of GS in both the catalytically active and inactive assembly states allows us to reveal an unanticipated self-assembly-induced disorder-order transition paradigm, in which the remote interactions between two subcomplex entities significantly rigidify the otherwise structurally fluctuating active sites, thereby regulating activity. We further show in vivo evidences that how the enzyme morphology transitions could be modulated by cellular factors on demand. Collectively, our data present an example of how assembly status transition offers an avenue for activity modulation, and sharpens our mechanistic understanding of the complex functional and regulatory properties of supramolecular enzymes.

Wheat root rot disease due to soil-borne fungal pathogens leads to tremendous yield losses worth billions of dollars worldwide every year. It is very important to study the relationship between rhizosphere soil fungal diversity and wheat roots to understand the occurrence and development of wheat root rot disease. A significant difference in fungal diversity was observed in the rhizosphere soil of healthy and diseased wheat roots in the heading stage, but the trend was the opposite in the filling stage. The abundance of most genera with high richness decreased significantly from the heading to the filling stage in the diseased groups; the richness of approximately one-third of all genera remained unchanged, and only a few low-richness genera, such as Fusarium and Ceratobasidium, had a very significant increase from the heading to the filling stage. In the healthy groups, the abundance of most genera increased significantly from the heading to filling stage; the abundance of some genera did not change markedly, or the abundance of very few genera increased significantly. Physical and chemical soil indicators showed that low soil pH and density, increases in ammonium nitrogen, nitrate nitrogen and total nitrogen contributed to the occurrence of wheat root rot disease. Our results revealed that in the early stages of disease, highly diverse rhizosphere soil fungi and a complex community structure can easily cause wheat root rot disease. The existence of pathogenic fungi is a necessary condition for wheat root rot disease, but the richness of pathogenic fungi is not necessarily important. The increases in ammonium nitrogen, nitrate nitrogen and total nitrogen contributed to the occurrence of wheat root rot disease. Low soil pH and soil density are beneficial to the occurrence of wheat root rot disease.

Published: December 2021

Hepatoid adenocarcinoma is a rare Alpha Fetoprotein (AFP) producing extrahepatic malignant tumour commonly seen in the stomach but can also arise from the ovary, endometrium lung. It is a rare type of adenocarcinoma with hepatocyte like histological differentiation and occurs outside the liver. In the lung, it is often presented as a bulky tumour, highly malignant, and associated with a poor prognosis. Early diagnosis and appropriate treatment options can result in long term survival. Here, authors reported a case of 58-year-old male patient, with no history of smoking presented as an Unknown Primary (UKP) with cervical and mediastinal lymphadenopathy which was later diagnosed histopathologically and confirmed by Immunohistochemistry (IHC) as Hepatoid Adenocarcinoma Lung (HAL) without any lesion in the lung on Computed Tomography (CT) chest. The serum AFP levels were normal. It expressed IHC markers Cytokeratin (CK7), CDX-2, Hep Par1 positivity, Thyroid Transcription Factor 1 (TTF-1) cytoplasmic positivity, and abnormally raised serum Carcinoembryonic Antigen (CEA). The patient was treated with definitive lower neck and mediastinal irradiation followed by adjuvant chemotherapy with five cycles of three weekly pemetrexed and carboplatin. Post treatment the serum CEA levels are decreasing and attained clinically complete response. The patient was in a close follow-up. To date, the review of literature about HAL didn’t showed any case presented as UKP with neck nodes without any lesion in the lung. The purpose of this case report was to present a new case of HAL with nodal metastasis, its unique histological findings, and its approach to diagnosis and treatment.
Gerber-Shiu Function in a Discrete-time Risk Model with Dividend Strategy
Authors: Huang Junqing , Bao Zhenhua
Published: December 2021

In this paper, a discrete-time risk model with dividend strategy and a general premium rate is considered. Under such a strategy, once the insurer’s surplus hits a constant dividend barrier , dividends are paid off to shareholders at  instantly. Using the roots of a generalization of Lundberg’s fundamental equation and the general theory on difference equations, two difference equations for the Gerber-Shiu discounted penalty function are derived and solved. The analytic results obtained are utilized to derive the probability of ultimate ruin when the claim sizes is a mixture of two geometric distributions. Numerical examples are also given to illustrate the applicability of the results obtained.
