Фактори ризику розвитку оклюзій артерій сітківки після кардіохірургічних втручань при клапанних вадах серця
Authors: Panchenko Yu.O. , Kovalchuk N.Ya.
Published: February 2024

Актуальність. Є повідомлення про розвиток оклюзії центральної артерії сітківки (ОЦАС) після інвазивних серцево-судинних процедур. Хірургічне втручання, операція на відкритому серці та післяопераційна кровотеча підвищували ризик ОЦАС. У кардіохірургії виокремлюють певні фактори ризику для ОЦАС, як-от: гігантоклітинний артеріїт, каротидний стеноз, інсульт, стан гіперкоагуляції, цукровий діабет з офтальмологічними ускладненнями, гострий коронарний синдром, фібриляція передсердь, застійна серцева недостатність, а також куріння. Матеріали та методи. Під спостереженням перебувало 380 пацієнтів (760 очей) із клапанною патологією серця після кардіохірургічних втручань. Проводилося дослідження характеру, частоти й особливостей розвитку та клінічного перебігу оклюзій артерій сітківки у цих хворих. Для виявлення факторів ризику розвитку оклюзій артерій сітківки у пацієнтів із клапанними вадами серця після кардіохірургічних операцій була вивчена залежність їх частоти від статі, віку, виду оперативного втручання, типу протеза серцевого клапана й операційного доступу. Результати. Частота артеріальних оклюзій сітківки після проведених кардіохірургічних втручань протягом 1 року спостережень у середньому становила 11,12 % (χ2 = 173,645; p < 0,001). При аналізі типів артеріальних оклюзій зафіксовано розвиток усіх типів оклюзій на 3-тю добу. На 10-ту добу та через 3 місяці спостерігалася тільки оклюзія ЦАС — 0,66 і 0,41 % відповідно. Через 1 рік було діагностовано тільки оклюзію гілки ЦАС — 0,32 %. Частота артеріальних оклюзій вища втричі у пацієнтів з віковим проміжком від 51 до 70 років і вдвічі у пацієнтів віком понад 71 рік порівняно з пацієнтами вікового діапазону 50 років і молодше (p = 0,042); після протезування клапанів частота оклюзій удвічі вища (p = 0,034), ніж після пластики; при використанні механічних імплантів частота оклюзій артерій сітківки збільшується на 62 % (p = 0,010) порівняно з біологічними імплантами; при використанні класичного доступу під час операції частота оклюзій артерій сітківки статистично значуще вища на 35 % порівняно з мінідоступом та в 11 разів порівняно з доступом через стегнову артерію (р < 0,001).
Порівняльна характеристика показників гемодинаміки ока у хворих на ускладнений і неускладнений рецидивуючий ідіопатичний передній увеїт
Authors: Khramenko N.I. , Konovalova N.V.
Published: February 2024

Одне з найпоширеніших структурних ускладнень увеїтів — це макулярний набряк, який є найчастішою причиною як оборотного, так і стійкого зниження гостроти зору. Втрата зору відбувається і через вторинну дистрофію макули внаслідок переднього увеїту. Крім того, прогресивно наростає частота вторинної глаукоми як ускладнення переднього увеїту. Характеристики гемодинаміки ока при ускладненому перебігу ідіопатичного рецидивуючого переднього увеїту в період загострення та ремісії мають відмінності залежно від характеру ускладнень. Визначення особливостей гемодинаміки ока при ускладненнях переднього увеїту має значення для призначення необхідної терапії і запобігання рецидивам. Значний рівень медико-соціальних та економічних втрат для суспільства в регіонах світу пов’язаний саме з ускладненнями хронічного запалення судинного тракту ока (переднього ідіопатичного увеїту).

Applying Weighted Taylor Series on Time Series Water Wave Modeling
Authors: Hutahaean Syawaluddin
Published: February 2024

This study develops a time series model for water waves using a weighted Taylor series approach to analyze water wave dynamics. The model incorporates the continuity equation, Euler's momentum conservation equation, and the Kinematic Free Surface Boundary Condition, all formulated through the weighted Taylor series. By integrating the modified continuity equation across the water depth, utilizing depth-averaged velocity concepts, we derive the water surface elevation equation. Similarly, applying the Euler momentum conservation principle to the water surface yields an equation for the horizontal water particle velocity, which is subsequently converted into an expression for the horizontal depth-averaged velocity. The equations for water surface elevation and horizontal water particle velocity are solved using numerical methods. The application of the numerical model results in the generation of four distinct wave profiles: sinusoidal, Stokes, cnoidal, and solitary wave profiles, classified according to Wilson's (1963) criteria. The emergence of each wave profile type is influenced by the specified input wave height.
A phenomenological insight into the use of pandemic pedagogy in the primary English Language Arts Grammar class
Authors: Constance Barbara , Pierre Richard
Published: February 2024

The Covid-19 Pandemic led to online teaching at all levels of education in Trinidad and Tobago. The teaching of all subject areas, including Grammar, had to be adjusted to suit this new educational paradigm. This study seeks to examine the pedagogical approaches to the teaching of Grammar at the primary level in Trinidad and Tobago during the Covid-19 period. The study utilized a hermeneutic phenomenological approach wherein the teachers were given an open-ended questionnaire covering aspects of teaching strategies employed during this pandemic. The findings reveal that while online teaching allowed for diverse teaching strategies, students’ over reliance on the grammatical tools made it challenging for teacher to determine whether they really grasped the concept.

Authors: Naik Shweta Sagar , Thilagaraj W. Richard , Gangadharan Pooja , Leela K.V.
Published: February 2024

In recent years, the rapid growth in Antimicrobial resistance (AMR) has become a global concern. Essential oils derived from plants that include bioactive components with proven antioxidative and antibacterial activities could be a potential solution to arrest this problem. In this study, antibacterial activities of DoTERRA essential oils such as Onguard, Clove, Teatree, Lavender and Eucalyptus were evaluated with Indian essential oils against clinical pathogenic bacteria. The GC-MS study revealed that cineole, terpinene, eucalyptol, and eugenol were the most prevalent bioactive components in these essential oils. The purity of the essential oils was confirmed with zeta potential and white light absorption spectrophotometer and shows that the Zeta potential of all the essential oils ranges from -51.4 to 0 mV. Using agar well diffusion and Micro broth dilution procedures, the antimicrobial activity of essential oils of clove, lavender, tea tree, eucalyptus, and On-Guard (combined) was assessed against several multi-drug-resistant bacteria. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of essential oils in aqueous and micellar solutions were determined by Micro broth dilution techniques. The most effective antibacterial essential oils were clove, tea tree, and On guard (a blended essential oil with a predominance of Limonene and Eugenol). The current research could result in development of formulas that contain micelle or colloid suspensions of whole essential oils such as clove, On-Guard, or Tea-Tree oil to aid in antimicrobial treatment.
Obsolete or Opportunity? Challenging Perceptions of Device Usefulness
Authors: Gupta Vedant
Published: February 2024

Abstract: Obsolete devices add to the rising levels of electronic waste, a major environ- mental concern, and a contributing factor to climate change. In recent years, device manufacturers have established environmental commitments and launched initiatives such as supporting the recycling of obsolete devices by making more ways available for consum- ers to safely dispose of their old devices. However, little support is available for individuals who want to continue using legacy or ‘end-of-life’ devices and few studies have explored the usefulness of these older devices, the barriers to their continued use and the associated user experiences. With a human-computer interaction lens, this paper reflects on device usefulness as a function of utility and usability, and on the barriers to continued device use and app installation. Additionally, the paper contributes insights from a sequel study that extends on prior work evaluating app functionality of a ‘vintage’ Apple device with new empirical data on app downloadability and functionality for the same device when newly classified as ‘obsolete’. A total of 230 apps, comprising the top 10 free App Store apps for each of 23 categories, were assessed for downloadability and functionality on an Apple iPad Mini tablet. Although only 20 apps (8.7%) could be downloaded directly onto the newly obsolete device, 143 apps (62.2%) could be downloaded with the use of a different non-legacy device. Of these 163 downloadable apps, 131 apps (com- prising 57% of all 230 apps and 80.4% of the downloadable apps) successfully installed, opened, and functioned. This was a decrease of only 4.3% in functional apps (of the 230 total apps) compared to the performance of the device when previously classified as ‘vin- tage’.

The power of role models: Influence on undergraduates' sense of purpose
Authors: Yang Guoliang , Wang Zhihua , Wu Weijiong , Wang Ruiming
Published: February 2024

We constructed a moderated mediation model to examine the mediating effect of social identification between the psychological distance of the role model and students' sense of purpose and the moderating effect of students' social comparison orientation on the relationship between psychological
distance of the role model and students' social identification, which subsequently affects their sense of purpose. Participants were 518 Chinese undergraduates who completed experiments in two studies, and a survey in a third study. Results showed that (a) after excluding the influences of
gender and major, psychological distance from their role models negatively predicted participants' sense of purpose; (b) social identification partially mediated the relationship between psychological distance and sense of purpose; and (c) social comparison orientation moderated the negative
effects of psychological distance on social identification. Our results show that for the practice of education by example, students should be guided to choose proximal role models as references to enhance their sense of purpose, and thereby reduce the hollow heart phenomenon.
Husain Faizhanov in the History of the Russian Oriental Studies
Authors: Mukhetdinov D. V.
Published: February 2024

This article summaries the results of research on the scientific activity of Husain Faizkhanov (1823–1866), especially taking into account the studies conducted during the passing year 2023. The expansion of the range of materials involved has led to the acquisition of new facts, as well as made it possible to revise some ideas about the general chronology of H. Faizkhanov’s life and rethink his direct contribution to various fields of oriental studies. The article shows that the arrival of H. Faizkhanov in Saint Petersburg, which took place at least in 1853, had already led him to close interaction with the Russian Imperial Academy of Sciences and he was involved in the transcription of manuscripts in Arabic, Persian and Turkic languages, consistently engaged in this work for many years. Faizkhanov was engaged by B. A. Dorn to compile the catalogue of Oriental manuscripts of the Imperial Public Library. Besides, it was with Faizkhanov that the first catalogue of Arabic manuscripts of the Asiatic Museum was started, which was only later completed by V. R. Rosen. The article also considers some circumstances of the initial period Faizkhanov’s life and, in this connection, the factors that influenced the formation of his personality.

Published: February 2024

Objective:  examine the effect of CNTNAP2 gene polymorphism on behavioral therapy response in Iraqi children with autism spectrum disorder using ABLLS-r.

Methods: In this study, 150 samples for autism spectrum disorder were obtained from AL-SIBTEIN ACADEMY, however owing to many challenges, the final number of samples was 50 patients. Polymerase Chain Reaction-Restriction refers to a technique that combines the use of polymerase chain reaction (PCR) with restriction enzymes to amplify and analyze certain DNA sequences. Fragment Length Polymorphism (PCR-RFLP) was used to genotype the CNTNAP2 gene at rs7794745. All 25 ABLLS-R repertoires and all four primary components had their dependent parameters determined by aggregating and converting the ABLLS data to a percentage. This provided us with the proportion of finished assignments from each repertoire.

Results: After correlating the genotype data (AA/AT/TT) with the behavioral therapy response as indicated by ABLLS-R, we only discovered a statistically significant difference between the frequency of AA/TT genotypes in the rs7794745 variant in patients and the social interaction domain. Conversely, the remaining 24 subdomains exhibited no discernible correlation.

Conclusion: This research topic could provide significant information on targeting and categorizing which skill areas need to be developed based on genetic models' influence.

Improved Accuracy for Trotter Simulations Using Chebyshev Interpolation
Authors: Rendon Gumaro , Watkins Jacob , Wiebe Nathan
Published: February 2024

Quantum metrology allows for measuring properties of a quantum system at the optimal Heisenberg limit. However, when the relevant quantum states are prepared using digital Hamiltonian simulation, the accrued algorithmic errors will cause deviations from this fundamental limit. In this work, we show how algorithmic errors due to Trotterized time evolution can be mitigated through the use of standard polynomial interpolation techniques. Our approach is to extrapolate to zero Trotter step size, akin to zero-noise extrapolation techniques for mitigating hardware errors. We perform a rigorous error analysis of the interpolation approach for estimating eigenvalues and time-evolved expectation values, and show that the Heisenberg limit is achieved up to polylogarithmic factors in the error. Our work suggests that accuracies approaching those of state-of-the-art simulation algorithms may be achieved using Trotter and classical resources alone for a number of relevant algorithmic tasks.

“National Women’s Issue”: Introduction
Authors:   Marjani Institute of History of the Tatarstan Academy of Sciences, Murtazina Lyalya R. , Khanipova Ilnara I. ,   Marjani Institute of History of the Tatarstan Academy of Sciences
Published: February 2024

The article opens a special issue of the journal “Historical Ethnology”, dedicated to the Tatar woman. Its authors, who acted as compilers and scientific editors of the issue, substantiate the research focus, chronology and source base of the published materials. The emphasis on Tatar women as an object of a special study is explained by their active social and professional stand during the period of the Russian Empire and the USSR. The coverage of these two historical periods made it possible to identify the ethnospecific logic of integrating Tatar women into large-scale political and social phenomena. The bulk of the articles included in the issue are accompanied by the publication of materials from state archives, ego-documents, literary works, articles from Tatar newspapers and magazines of the pre-revolutionary period, inaccessible to most researchers. Their introduction into scientific circulation, according to the authors of the introductory article, strengthens the possibilities of a diachronic approach to the analysis of the ethnosocial field from a historical perspective. Giving a brief overview of the articles in the issue, the authors of the introduction come to the conclusion that in the era of bourgeois reforms, along with the traditional care for family and children for women, her role in the society is strengthening; her desire for education and educational activities is intensifying. With the advent of the Soviet system, which proclaimed gender equality of the sexes, the burden on women increases both in their personal life and in the public sphere. At the same time, Tatar women retain their most important purpose – educating and bringing up the younger generation.

Rukiya Mukhammadish on the role of Tatar women in the life of the people
Authors:   Marjani Institute of History of the Tatarstan Academy of Sciences, Murtazina Lyalya R.
Published: February 2024

The article analyses the views of a prominent representative of the Tatar emigration, teacher, journalist, and public figure Rukiya Mukhammadish on the Tatar woman and her role in the fate of the people. The work is accompanied by a publication written by Rukiya Mukhammadish in the newspaper “Milli Bayraq”, which was published in Mukden, Manchuria in 1935–1945. The publication made a considerable contribution to the enlightenment and the cultivation of national identity among the Tatars in the Far East. The presented source is dedicated to highlighting the role of the Tatar woman in the national education, life and history of the people in various periods of its existence. In the article “Woman in the Life of Our Nation”, R. Mukhammadish sets a goal to show the place of women in the family, in the life of the people and the state, and gives examples from various historical sources. According to the author, the position of women in the Turkic society was quite free; they were distinguished by their courage, determination and participated in solving not only family but also state-related issues. Women of the Golden Horde participated in the government affairs; in the Kazan Khanate, they ruled the country. The upbringing of mothers and Abystays helped to preserve Islam, their native language, and folk traditions. Thus, women fulfilled their responsibilities not only to their family, but also to the people and the country. The purpose of the presented article is to raise the national self-awareness (“milli barlyk”) of Tatar emigrants and disseminate historical knowledge among them. The relevance of documents of this nature lies in the fact that they are valuable sources for studying the life and features of the development of social and pedagogical thought of the Mukhadzhir Tatars.

Innovative food products in the eyes of Polish young consumers
Authors:   West Pomeranian University of Technology, Hernik Joanna , Grinberga-Zalite Gunta ,   Latvia University of Life Sciences and Technologies, Mazur Rafal ,   West Pomeranian University of Technology
Published: February 2024

This article discusses the acceptance of innovative food products – i.e. new and unconventional products that have not been widely consumed so far. The aim of the article is to determine the level of acceptance of innovative food products by young Poles. We put a thesis that innovative food products are not readily accepted and that consumers do not perceive them as worth more than typical food products. Thus, food products are difficult to be subjected to major innovations. The research methodology was based on the literature review summarizing scholarly literature on the chosen research topic, a questionnaire survey, comparative analysis and logical construction research methods. This study is essential from at least two perspectives: 1) acceptance of novelties is important for the authorities shaping social policies regarding sustainable development and food security; 2) understanding the customers is important for food industry companies that want to introduce new products to the market. Food preferences are often tied to cultural traditions, which can make it difficult for new or unfamiliar foods to gain traction. This is confirmed by the results of the study elaborated in the article: the approach of respondents to innovative food products is ambiguous - they agree that such products are beneficial for people and the Earth's resources, but not always they are ready to use them themselves. The research also shows that innovative products would not be accepted immediately and consumers would need time to get used to them. Therefore, the authorities shaping social policies regarding sustainable development and food security, as well as food producers, should plan educational campaigns explaining the benefits of alternative food sources and innovative food products.

The study investigates "Optimizing Cement Stabilization for Lateritic Soil in the Takie Area of Ogbomoso" and presents a comprehensive analysis of geotechnical properties. The research encompassed particle size determination and Atterberg limits testing to classify the samples, primarily composed of lateritic soil. The results detailed the particle size distribution and indicated the soil’s composition, predominantly sand with gravel and unaccounted finer silt content. The Atterberg limits testing revealed variations in plastic and liquid limits across different cement percentages. Additionally, dynamic and static compaction tests were performed, indicating Optimum Moisture Content (OMC) and Maximum Dry Density (MDD). The static compaction involved replacing proportions of bulk sand with cement for each percentage addition. The study achieved its objective of understanding soil properties for stabilization purposes, offering insights into the impact of varying cement content on soil characteristics and compaction. The abstract emphasizes the comprehensive investigation into lateritic soil properties and the influence of cement stabilization, vital for engineering applications in the Takie area of Ogbomoso.

Ważne jest, aby ta grupa współczynników była łatwa do wykrycia, ponieważ ich wartość jest równa 0 lub ±1. Nazywano je współczynnikami logicznymi, w przeciwieństwie do współczynników technicznych. W artykule przedstawiono wzory opisujące zmienność współczynników technicznych rzeczywistych zmiennych podstawowych przy tzw. warunkach ścisłych w decyzji optymalnej. Wzory te opierały się na liniowych efektach zmiany współczynników kosztu i prawej strony pomimo nieliniowej zależności pomiędzy zmieniającymi się współczynnikami technicznymi a zmiennymi bazowymi. Dzięki takiemu rozwiązaniu łatwo jest uzyskać miary stabilności w przypadku zmiany współczynników technicznych.
Reliability-based design optimization of screw shaft for continuous high-pressure hydrothermal co-liquefaction process
Authors: Venkatachalam Chitra , Bhuvaneshwaran Premkumar , Sengottian Mothil , Ravichandran Sathish
Published: February 2024

Hydrothermal co-liquefaction (HTCL) is the prominent process for producing bio-products with a higher conversion rate. It is performed at high temperatures and pressure in the presence of water. Earlier, it was mostly conducted in batch reactors, but it has major limitations including operating volume, back mixing, and tedious process for high productivity. With that, the present investigation is performed on designing the screw shaft for the high-pressure HTCL process. The dimensional factors including flight length, pitch, helix angle, and depth were considered to design the optimal screw shaft. Likewise, principal stresses, shear stress, bending stress, bending moment, and total deformation were regarded as inevitable response variables to analyze the internal strength of the shaft. In this regard, the Taguchi approach provides the L9 (34) orthogonal array as an experimental design. Then, the numerical results from the transient structural analysis were analyzed with the assistance of statistical methods such as Grey Relational Grade (GRG), Grey Fuzzy Reasoning Grade, Analysis of Variance (ANOVA), and Taguchi method to find the most influential dimensions for minimizing the response variable. Consequently, the results from both GRG and Taguchi optimization were compared, and selected the most optimum parameters.
The Impact of the CPA Evolution on Students’ Interest in Earning a CPA License and Working in Public Accounting
Authors: Johnson Tristan , Lang Bradley , Mauldin Shawn
Published: February 2024

The CPA Evolution is a joint initiative of the AICPA and NASBA to ensure the continued relevance of the CPA exam and to increase CPA licensure. Beginning in January 2024, a core plus discipline approach requires all candidates to pass three core exam sections and one of three discipline sections. This study examines whether this new exam format affects an individual’s interest in earning the CPA license and working in public accounting. The results of an experiment suggest that the new exam format significantly increases interest in earning a CPA license and that this effect is driven by nonaccounting major students who have career preferences in the accounting profession. Additionally, the new exam format marginally increases interest in working in public accounting, specifically with nonaccounting majors with career preferences in accounting. Our results indicate the CPA Evolution may help address the current pipeline staffing shortages in the field of accounting.

Loan-Level Disclosure and the Convenience Yield of Asset-Backed Securities
Authors: Schmidt Brent A. , Zhang Haiwen
Published: February 2024

We examine the impact of transparency on the convenience yield of AAA-rated asset-backed security (ABS) tranches. AAA tranches of ABS are commonly held by investors to manage financial liquidity and therefore enjoy a price premium beyond what is determined solely by the expected monetary payoff (i.e., convenience yield). The Securities and Exchange Commission (SEC) requires ABS issuers to provide monthly disclosures about the performance of the underlying individual loans for ABS issued after November 23, 2016 to improve transparency. We document that AAA tranches of ABS experience a significant increase in price volatility after the loan-level disclosure mandate. As a result, the use of these tranches as collateral for short-term funding and their convenience yield decrease significantly after the increased disclosure. Our collective evidence highlights an important unintended consequence of increased transparency in the ABS market; it diminishes the pledgeability of long-term safe assets.

Background: Telerehabilitation has become increasingly popular since the SARS-CoV-2 (COVID-19) outbreak. However, studies are needed to understand the effects of remote delivery of spine treatment approaches.
Objectives: To verify and compare the effects of traditional rehabilitation programmes (in-person) and telerehabilitation (online) on the progression of scoliotic curvature in adolescents with idiopathic scoliosis during the COVID-19 pandemic, and to verify the acceptability, appropriateness, and feasibility among patients and physiotherapists regarding both treatments.
Methods: This is a cohort study (prospective analysis of 2 intervention groups: telerehabilitation (online) and traditional rehabilitation (in-person). A total of 66 adolescents with idiopathic scoliosis were included. Recruitment was conducted through the Clinical Center in Scoliosis Care (January–December 2020). Participants were divided into 2 intervention groups: telerehabilitation (online) (n = 33) and traditional rehabilitation programme (in-person) (n = 33). Both groups also were supplied with a spinal orthopaedic brace. Scoliosis was confirmed by a spine X-ray examination (Cobb angle). Radiographic parameters measured were: Cobb angles (thoracic and lumbar). The method of Nash and Moe (thoracic and lumbar) was also evaluated based on the relationship between the vertebral pedicles and the centre of the vertebral body in the X-rays. Assessments were performed at baseline (T0) and after 6 months of the intervention protocol (T6). Patient and physiotherapist reports were evaluated on the acceptability, appropriateness, and feasibility of the interventions.
Results: Adolescents with idiopathic scoliosis showed a significant decrease in the Cobb angle (main scoliotic curvature), with a 4.9° for the traditional rehabilitation programme and 2.4° for the telerehabilitation. Thoracic and lumbar Cobb angles did not show significant changes after the intervention in both groups or between groups. Thoracic and lumbar Nash and Moe scores scores also did not show significant differences after 6 months of in-person or telerehabilitation intervention, or between groups. The intervention by telerehabilitation was acceptable, appropriate, and feasible for patients and physiotherapists.
Conclusion: Use of the rehabilitation programme for adolescents with idiopathic scoliosis, delivered via telerehabilitation during the COVID-19 pandemic, was encouraging for future applications due to the improved effect on reducing the Cobb angle, preventing progression of scoliosis. In addition, telerehabilitation showed good acceptability among patients and physiotherapists. Traditional rehabilitation programmes (in-person) in adolescents with idiopathic scoliosis also showed a reduction in the Cobb angle.

A definição ácido-base de Arrhenius dos livros-textos de química: a história de um obstáculo epistemológico e suas consequências para o ensino-aprendizagem
Authors: Herbst Marcelo
Published: February 2024

A assim chamada definição ácido-base de Arrhenius, presente em vários livros-textos de Química no Brasil, foi analisada tanto do ponto de vista epistemológico, usando o referencial teórico dos obstáculos epistemológicos de Gaston Bachelard, quanto do ponto de vista histórico, através de pesquisa bibliográfica em publicações originais dos químicos Svante Arrhenius e Justus von Liebig, bem como em materiais relacionados à história das definições ácido-base. O objetivo deste trabalho é contribuir para a problematização do ensino das definições ácido-base, a partir do questionamento da definição atribuída a Arrhenius e amplamente disseminada na comunidade química no Brasil. Não foram encontradas evidências bibliográficas que demonstrem que Arrhenius tenha cunhado alguma definição ácido-base, e a partir dessa constatação é proposto que a definição atribuída a Arrhenius nos livros-textos é uma acomodação/amalgamação da teoria da dissociação eletrolítica de Arrhenius com a longeva definição de Liebig para ácidos, baseada na presença de hidrogênio e aceita pelos químicos no século XIX. Argumenta-se que a definição ácido-base atribuída a Arrhenius nos livros-textos é também errônea, uma vez que soluções aquosas ácidas ou básicas podem ser preparadas sem a adição de solutos contendo íons hidrogênio ou hidroxila. É proposto que o obstáculo epistemológico substancialista representado pela exigência de hidrogênio na composição dos ácidos foi responsável pela transferência de fidelidade da definição de ácidos de Liebig para a teoria iônica de Arrhenius, uma vez que esta pode explicar a reatividade de ácidos e eletrólitos em geral em solução aquosa. As consequências do ensino da errônea definição ácido-base atribuída a Arrhenius são discutidas, e estratégias didáticas para o ensino das definições ácido-base no ensino médio e nos cursos de formação inicial e continuada de professores de química e ciências são apresentadas.
150 anos de investigação após a descoberta de Enrico Sertoli
Authors: Calado Ana Margarida
Published: February 2024

Resumo
A complexa morfologia das células de Sertoli, bem como as suas interações com as células germinativas tem sido foco de investigação desde que a sua descrição pela primeira vez em 1865 por Enrico Sertoli. Nos últimos anos, a investigação no âmbito das células de Sertoli vai muito além da morfologia, da fisiologia e tornou-se cada vez mais focada nas questões moleculares. O objetivo dos investigadores tem sido entender o papel das células de Sertoli na espermatogénese e aplicar essa informação em problemas relacionados à fertilidade masculina. Os numerosos e distintos complexos juncionais e especializações de membrana entre as células de Sertoli e as células germinativas proporcionam um microambiente para o desenvolvimento das células germinativas, definindo dois compartimentos anatómica e fisiologicamente distintos no túbulo seminífero. As células de Sertoli constituem uma população de células que não se dividem, mas que se encontra ativa durante a vida reprodutiva, alterando ciclicamente a sua morfologia e a expressão génica de forma a contribuírem para o inicio da onda espermática e cooperação com a espermatogénese.
Esta revisão, destacaremos os principais avanços científicos relativos ao importante papel das células de Sertoli na espermatogénese, na diferenciação do testículo, na determinação do sexo e em questões clínicas que envolvem interação das células de Sertoli com células germinativas.

Abstract
The complex morphology of Sertoli cells, as well as their interactions with germ cells, has been the focus of investigation since their first description in 1865 by Enrico Sertoli. In recent years, Sertoli cell research has gone far beyond morphology and physiology and has become increasingly focused on molecular issues. The researchers' goal has been to understand the role of Sertoli cells in spermatogenesis and to apply this information in problems related to male fertility. The numerous and distinct junctional complexes and membrane specializations between Sertoli cells and germ cells provide a microenvironment for germ cell development, defining two anatomically and physiologically distinct compartments in the seminiferous tubule. Sertoli cells constitute a population of cells that do not divide, but are active during reproductive life, cyclically changing their morphology and gene expression in order to contribute to the initiation of the sperm wave and cooperation with spermatogenesis. In this review, we will highlight the main scientific advances regarding the important role of Sertoli cells in spermatogenesis, testis differentiation, sex determination and clinical issues involving Sertoli cell interaction with germ cells.
