Differences in referral path, clinical and radiographic outcomes between seronegative and seropositive rheumatoid arthritis Mexican Mestizo patients: A cohort study
Authors: Guaracha-Basáñez Guillermo Arturo , Contreras-Yáñez Irazú , Ortiz-Haro Ana Belén , Pascual-Ramos Virginia
Published: June 2024

Background

The study compared the referral path, the first two-year clinical outcomes, and the first five-year radiographic outcomes between seronegative patients (SNPs) from a recent-onset rheumatoid arthritis dynamic cohort initiated in 2004 and seropositive patients (SPPs). Predictors of incidental erosive disease were investigated.

Patients and methods

Up to March 2023, one independent observer reviewed the charts from 188 patients with at least two years of clinical assessments and up to five years of annual radiographic assessments. SNPs were defined when baseline RF and ACPA serum titers were within local normal ranges. The erosive disease was defined on hand and/or foot radiographs when at least one unequivocal cortical bone defect was detected. The incidental erosive disease was defined in baseline erosive disease-free patients who developed erosions at follow-ups. Multivariate Cox regression analyses identified hazard ratios (95% confidence interval) for factors to predict incidental erosive disease.

Results

There were 17 (9%) SNPs, and they had a shorter time from symptoms onset to first physician evaluation, visited a lower number of physicians, and received less intensive treatment at referral and during the first years of follow-up than SPPs. Also, they had fewer 0–66 swollen joints and were less frequently persistent on therapy. The erosive disease was detected only in SPPs, and its frequency increased from 10.1% at baseline to 36.1% at the five-year radiographic assessment. There were 53 (31.4%) patients with incidental erosive disease, and differences between SPPs and SNPs were statistically significant at the feet location. Incidental erosive disease was predicted by baseline ACPA, ESR, substantial morning stiffness, and cumulative CRP.

Conclusions

SNPs showed mild differences in their referral path and clinical outcomes compared to SPPs. However, erosive disease was detected only in SPPs and was predicted by baseline and cumulative clinical and serologic variables.
An innovative protocol to increase egg production of chicken layers
Authors: Alaraji Furkan
Published: June 2024

This study investigated the effects of different doses of limestone, light durations, light intensities, and vitamins on both the productive performance and egg quality. The study utilized two rearing houses (control and treatment), each accommodating 75000 Lohmann Brown Classic chicks reared in open-sided rearing cages from one day old until they reached 89 weeks of age. Throughout the laying period, the hens were subjected to a specific light regimen (light = 14 h; dark = 10 h a day). At the end of experiment, the treatment group displayed significant (p<0.05) differences compared to the control group across various parameters. Notably, the treatment group exhibited lower daily feed intake (treatment: 112 g/bird vs control: 115 g/bird), 9.6% higher egg production (treatment: 78.5% vs control: 68.9%), lower body weight (treatment: 2057 g vs control: 2073 g), lower feed conversion ratio (FCR)/egg (treatment: 1.44 vs control: 1.69), higher egg weight (treatment: 69.4 g vs control: 68.5 g), greater egg mass (treatment: 56.14 vs control: 48.76), greater shell thickness (treatment: 3.52 mm vs control: 3.44 mm), and greater shell weight (treatment: 9.3 g vs control: 8.79 g). However, the albumin weight, yolk weight, yolk diameter, shape index, and Haugh units (HU) were not significantly (p˃0.05) affected after 75 weeks of treatment when compared with those of the control group. Therefore, this study is the first of its kind to demonstrate that different ratios of limestone, different durations and intensities of light, and different vitamin supplementation doses in the treatment group (subjected to the novel rearing recommendations described in this study) may yield a profit of 180,541 USD, exceeding the baseline profit of the control group (subjected to conventional rearing methods).
Viral load non-suppression status among women exposed to Dolutegravir-based versus Efavirenz-based regimens in Ethiopia: A before-and-after study
Authors: Facha Wolde , Tadesse Takele , Wolka Eskinder , Astatkie Ayalew
Published: June 2024

Background

High viral load during pregnancy and breastfeeding period is the risk factor for vertical transmission of human immunodeficiency virus (HIV). Currently, Dolutegravir (DTG)-based regimens are recommended to attain adequate viral load suppression (VLS) among women. However, its effect on VLS has not been investigated among women in PMTCT care in Ethiopia.

Objective

This study aimed to investigate the rate of viral load non-suppression among women exposed to DTG-based versus Efavirenz (EFV)-based regimens in Ethiopia.

Methods

An uncontrolled before-and-after study design was conducted among 924 women (462 on EFV-based and 462 on DTG-based regimens) enrolled in PMTCT care from September 2015 to February 2023. The outcome variable was the viral load (VL) non-suppression among women on PMTCT care. A modified Poisson regression model was employed, and the proportion was computed to compare the rate of VL non-suppression in both groups. The risk ratio (RR) with a 95% confidence interval (CI) was calculated to assess viral load non-suppression among women on DTG-based and EFV-based regimens by adjusting for other variables.

Results

The overall rate of non-suppressed VL was 16.2% (95% CI: 14.0–18.8%). Mothers on DTG-based regimens had approximately a 30% (adjusted risk ratio (aRR): 0.70; 95% CI: 0.52–0.94) lesser risk of developing non-suppressed VL than women on EFV-based regimens. Besides, older women were 1.38 times (aRR: 1.38; 95% CI: 1.04–1.83); mothers who did not disclose their HIV status to their partners were 2.54 times (aRR: 2.54; 95% CI: 1.91–3.38); and mothers who had poor or fair adherence to antiretroviral (ARV) drugs were 2.11 times (aRR: 2.11; 95% CI: 1.45–3.07) at higher risk of non-suppressed VL.

Conclusion

Women on DTG-based regimens had a significantly suppressed VL compared to those on EFV-based regimens. Thus, administering DTG-based first-line ART regimens should be strengthened to achieve global and national targets on VLS.

Issue 3.1 presents several views and debates concerning luxury, beginning with a focus on legislation and the emergence of sumptuary laws in the ancient and premodern world and ending with a consideration of luxury as a global force in contemporary multicultural society. From economic and moral perspectives, we move towards psychology as a means to understand the ultra-high net worth luxury consumer through an analysis of psychographics as a means of defining and properly targeting this market. We consider the historical and social forces that shaped the experience and practices of the dandy in the 1890s, and industry standards and practices and consumer motivations are investigated with respect to menswear and high-end audio systems.
Why craftsmanship is an essential ingredient in luxury menswear
Authors: Montgomery Bruce
Published: June 2024

The luxury menswear industry is one of the growing areas of the fashion business in an albeit saturated marketplace. Luxury menswear brands are evolving as they endeavour to remain relevant and at the top of the fashion pyramid. To continue growth, many luxury brand groups have expanded across product areas. These include automobiles, jewellery, luxury hotels, fragrances and yachts, as well as clothing. To get even greater attention, the luxury menswear brands have recently reviewed their marketing campaigns with bolder approaches including experiences on global cultural sites and dabbled with the metaverse. However, with this foray into virtual technologies maintaining a high level of craft quality within all products is essential for continuity. This is a theoretical positional article that discusses what are the challenges facing the luxury sector such as global developments, local policies and social issues that affect the luxury menswear industry. The article emphasizes that craft skills are still very much at the forefront to create the type of products needed to meet the luxury market demand and business needs of the future. This qualitative study highlights that a large percentage of luxury menswear is now being purchased by a Generation Z brand consumer who puts pressure on luxury brands to incorporate their values. It considers the problems in maintaining craft skills, bespoke and why they are key to enhance luxury menswear provenance and stop it becoming bland, monotonous and mass-produced.

Tolkien fanzines, fandom and the literary tradition in the 1960s
Authors: Wisniewski Mark
Published: June 2024

This article summarizes the manner in which fanzine authors contextualize J. R. R. Tolkien’s fiction within diverse literary traditions. Although rarely the topic of academic discussions in the 1960s, fanzine authors regularly contextualize The Hobbit, The Lord of the Rings, and Tolkien’s unfinished fiction in terms of genre, canon and literary tradition. After examining and categorizing the authors and texts discussed in 80 fan letters and articles, I found that fan authors are almost evenly divided in the ways they contextualize Tolkien’s fiction: as part of the fantasy tradition, as an inheritor of the epic or mythological genealogy, or as part of a third more eclectic tradition.
Reconstructive nostalgia in later life fandom
Authors: Smith Joseph Andrew
Published: June 2024

Older people are often stereotyped as being ‘stuck in the past’. They are seen as liable to moaning about change, of disliking new, contemporary culture, of living in the sweet embrace of nostalgic reminiscence. This article argues that a form of nostalgia – which I call reconstructive nostalgia, based on the work of Svetlana Boym – is an important part of fandom in the later life course. It is crucial for fannish object-relating, as this nostalgic process enables long-term fans to remain engaged with their favourite cultural texts, which change – sometimes fundamentally – across many decades. Based on in-depth interviews with 35 older sports fans (average age 72.5 years), this article introduces a new type of non-pejorative nostalgia to describe the process whereby an individual cherry picks aspects of a remembered text, and ‘reads’ those characteristics in the contemporary text, thus strengthening the subject-object bond. This textual manipulation helps to nurture ontological security, as the long-term fan seeks to retain their favourite text(s) as a central pillar of identity
Fandom identification and in-person activities as mediators of the association between cosplay and psychological well-being
Authors: Leshner Connor E. , Reysen Stephen , Plante Courtney N. , Roberts Sharon E. , Gerbasi Kathleen C.
Published: June 2024

Cosplay, a portmanteau of the words ‘costume’ and ‘roleplay’, involves fans dressing up and acting out fictional characters, usually at fan-themed events. Previous research on cosplay and well-being has found that people who cosplay, compared to non-cosplaying anime fans, experience more positive well-being, in part because they are more likely to disclose their fan interests to others rather than hiding it. In the present study we expand upon prior research by testing whether fandom identification and attending events mediate the association between cosplaying (i.e. a sample of cosplayers vs. non-cosplaying anime fans) and well-being. The results provide evidence for a serial mediation model consistent with our predictions and with prior findings. We discuss implications for measuring well-being in fan communities, including both cosplayers and non-cosplaying fans, as well as the potential benefits of in-person contact with members of one’s fandom.

Blood, sweat and tears: Kinning otherwise through art
Authors: Vaage Nora S. , Lie Merete
Published: June 2024

The article discusses two bioart projects that bring the symbolically core human substances of blood, sweat and tears into technologically mediated relationships with plants and fungi to explore human kinship with other species: Tarah Rhoda’s BS&T (short for ‘blood, sweat and tears’) and OurGlass, and Saša Spačal’s MycoMythologies: Patterning. The article analyses the art projects through the lens of the molecular gaze and different perspectives on kinning, bringing anthropological conceptualizations of kinship together with Haraway’s pathways to connect with other species. How can bioart use technologies to explore interspecies kinship through a molecular gaze? And may such artworks contribute to the toning down of human exceptionality in the face of a precarious future? We find that artworks providing a molecular gaze on interspecies biological processes may risk a decontextualized approach to complex relational processes but may also create new visions of filiation even with biological organisms imagined to be genetically distant from humans, thus spurring awareness of the fragile interrelationships among species.
Hermogenes’ Progymnasmata
Authors: Rosário Pedro
Published: June 2024

Relying on the historical-critical method, I propose an analysis of the nature of the Gospel of Luke and its possible dependency on Greek rhetorical conventions. Taking into account the highly literate nature of this Gospel, this paper puts forward the case that its author has been educated in the Greek rhetorical exercise of encomion, as documented in Hermogenes’ progymnasmata. Empowered by his knowledge of encomion, Luke probably used Mark as a template to compose a eulogy of Jesus of Nazareth. In light of this, I suggest a list with the correspondence between Hermogenes’ encomiastic topics and the pericopae used by Luke in his Gospel. Considering the hypothesis that the Gospel of Luke is best understood as an encomion, I propose an assessment of its implications to the reconstruction of the historical Jesus.
Nikos Orphanides
Authors: Tanga Fabio
Published: June 2024

Le tormentate vicende politiche relative all’indipendenza di Cipro, ai conflitti etnici tra greco-ciprioti e turco-ciprioti sull’isola e all’invasione turca del 1974, hanno contribuito alla nascita di una generazione di poeti ciprioti, tra cui spicca la figura di Nikos Orphanides, che ha composto due liriche ispirate all’Antigone sofoclea. Il poeta e saggista, originario della zona di Cipro attualmente occupata dalle forze turche, trae ispirazione dalla tragedia dedicata da Sofocle alla figlia di Edipo per identificare in Antigone il paradigma di una relazione amorosa turbolenta, il simbolo della patria perduta e la paladina della lotta per i diritti civili e del diritto alla sepoltura dei caduti greco-ciprioti all’interno delle terre occupate. Così, in una sorta di dittico poetico, Orphanides sviluppa diversi motivi presenti nell’Antigone di Sofocle ricontestualizzandoli nella storia contemporanea dell’isola di Cipro, al fine di offrire un modello archetipico di lotta civile esente da narrazioni edulcorate e da magniloquenti esaltazioni di maniera.
Kulturális rendszerek elsajátítása és használata
Authors: Pléh Csaba
Published: June 2024

Az ember kognitív tevékenységét számos kulturális rendszer teszi lehetővé, illetve irányítja. A mai evolúciós irányultságú kognitív pszichológia ezeket a rendszereket nem egyszerűen a ’magas kultúra’ és az iskoláztatás konstruált következményeinek tartja, hanem olyan, beállítást és egyéni élet során történő stabilizációt igénylő reprezentációs fordulatok (Merlin Donald) eredményeinek, melyek az ember biológiai alapú szocialitásának és a kultúra önkényeit elfogadó természetes pedagógiai hozzáállásának (Csibra és Gergely) a következményei. A természetes nyelv mint egyetemes rendszer lehetővé teszi nemcsak a távoli dolgokról való kommunikációt, hanem a nem közvetlenül észlelt tudások elsajátítását, a Russell értelmében vett kettős episztemológia (érzékelésen és leíráson alapuló tudás) megjelenését is. A nyelv mint elsődleges kulturális rendszer egyszerre ad számunkra kódokat és általános, illetve specifikus tudásokat. Ugyanaz érvényes a másodlagos kulturális rendszerekre, az írás/olvasás, számolás, zene stb. rendszereire is. A dolgozatban elsősorban az olvasásra és a webalapú tudásszervezésre összpontosítva bemutatom ezeknek a másodlagos rendszereknek néhány feszítő jellemzőjét, melyek a kognitív kutatás és a szervezett oktatás közös kérdéseibe helyezik őket. A másodlagos rendszerek, miközben lassan alakulnak ki az egyénnél, működésükben ugyanolyan gyorsak és hatékonyak, mint az észlelés elsődleges rendszerei. Miközben nincsenek evolúciósan kialakult előre specializált moduláris idegrendszeri „központjaik”, egy idegrendszeri újrahasznosítás (Dehaene) révén megtalálják a működtetésükhöz optimális agykérgi rendszereket. A paradoxonok mellett kitérek a mai legújabb rendszerek felvetette gondokra is. Vajon a digitális eszközök támogatta feladatmegoldás, a képernyőn keresztüli állandó vándorlás, az állandóan hozzáférhető tudásrendszerek kattintásnyi távolsága és például a webalapú tudáskeresés ki fogja-e alakítani a maga idegrendszeri fülkéjét, mint az olvasás tette volt, illetve visszafejleszti-e vagy új kategorizációkra készteti-e a meglevő kognitív rendszereinket?

Published: June 2024

Sugarcane bagasse (SB) like other lignocellulosic materials contains high levels of insoluble dietary fibers (IDF) that can be extracted using various treatments. Moreover, the extracted IDF properties were found to be dependent on the implemented treatment. Thus, this study set out to evaluate the impact of five treatments (NaOH, NaOH+H2O2, NaOH+H2SO4, PAA (peracetic acid) and NaOH+PAA) and the subsequent bleaching treatment on the physicochemical, structural, and functional properties of SB fiber. In addition, the effect of particle size reduction on the physicochemical and functional properties was investigated. Lignin content, holocellulose content, XRD, FT-IR, and whiteness index were used to characterize the extracted fibers and to evaluate their structural modifications. The experiments confirmed that NaOH+PAA treatment extracted fibers that had the lowest lignin content (1.65%) and highest holocellulose content (93.07%) and exhibited the highest whiteness index (83.37). The high crystallinity index of NaOH+PAA extracted fibers in addition to the disappearance of spectral bands at 1512, 1595, 1620 and 1730 cm–1 of NaOH+PAA FT-IR spectrum confirms the preceding outcomes. The water holding capacity (WHC) and oil binding capacity (OBC) of NaOH+PAA extracted fiber and other extracted fibers were improved as a result of bleaching treatment. Reducing the particle size of treated bleached samples to > 500 μm significantly decreased their WHC and OBC whereas increased their α-amylase inhibitory activity. The obtained results indicate that NaOH+PAA is a promising method for the extraction of fibers from SB under moderate conditions.

Published: June 2024

Diabetes Mellitus (DM) is a chronic disease that occurs when the pancreas does not produce enough insulin, or the body cannot use insulin effectively. Type 2 DM treatment can be done using antidiabetic drugs, but the continuous use of synthetic drugs will cause side effects. Empirically, the people of Nias Indonesia use palm juice (Arenga pinnata Merr.) as an antidiabetic, which can reduce blood glucose levels. This study aimed to find the active compounds in palm juice that can potentially be an antidiabetic type 2 using an in silico approach. The methods used were toxicity screening, profile pharmacokinetics, drug scanning, docking, and molecular dynamics simulation. Screening, molecular docking, and molecular dynamics of 30 compounds generated from pyrazine and furan revealed that two compounds, PF 16 and PF 30, can bind to receptors and produce lower ∆G values than metformin HCl. Molecular dynamics simulation results using the MM-GBSA calculation method showed that the PF 16 compound was more selective than the 2PDY (aldose reductase) with a value of -39.23 kcal/mol, while compound PF 30 was more selective to 1Z89 (aldose reductase) with a value of -7.36 kcal/mol. It can be concluded that the level of affinity of the PF 30 compound to the 1Z89 receptor and the PF 16 compound to the 2PDY were predicted to have the potential as antidiabetic (DM type 2).

Authors: Lutsenko N. S. , Isakova O. A. , Rudycheva O. A. , Kyrylova T. S.
Published: June 2024

Aim. To analyze the risk factors for the development of posterior subcapsular cataract in patients with different morphological changes using anterior segment optical coherence tomography.
Materials and methods. A prospective clinical study on the risk factors for posterior subcapsular cataract was conducted during 2020–2022. The study involved 296 patients (512 eyes). The morphological type of the posterior capsule was evaluated using anterior segment optical coherence tomography (AS OCT), Optovue RTVue 100 XR Avanti (Optovue Inc., USA).
Results. Significant differences have been found between the first and second types of morphological changes in the posterior lens capsule in diabetes mellitus, long-term steroid use and myopia (χ2 = 68.01, р ≤ 0.0001), as well as between the second and third types of posterior capsule changes in myopia (χ2 = 16.97, р ≤ 0.0001). In the third type of morphological changes in the posterior lens capsule, mainly hereditary risk factors for the development of capsule opacification have been identified, namely, a history of retinitis pigmentosa in 77.8 % of cases, congenital myopia – in 22.2 %.
Conclusions. Defining the morphological type of posterior capsule opacities coupled with studying the etiology of the process provide new knowledge concerning the prediction of visual functions and the phacoemulsification technique for posterior subcapsular cataract.
Accelerated biological ageing as a complication of cancer therapy

Published: June 2024

Aim. The paper aimed to update the study on accelerated biological aging as a complication of cancer therapy with a focus on diagnosing and prognosing the disease course.
The authors independently searched scientific literature for the systematic review within databases PubMed, Scopus and Cochrane in the period from 2018 to 2024, using combinations of keywords “cancer”, “biological aging”, “replicative aging”, “antitumor therapy”, “markers of cellular senescence”, “coronary artery calcium” and selected full-text publications written in English and Ukrainian with level 1–3 evidence.
People affected by cancer grow old faster. This could be related to malignant growth biology as well as to methods of anticancer therapy received. Cytostatics, targeted, hormonal and immune drugs damage not only malignant, but also benign cells, which leads to violations of replication with sustained cell cycle arrest and other phenotypic signs – macromolecular damage, metabolic changes, production of a specific senescence-associated secretome. Clinically, this is manifested by reduced work capacity, weakness, chronic organ dysfunction, cardiovascular disorders, progression of coronary atherosclerosis, hypertension, diabetes, dyslipidemia, sarcopenia, cognitive disorders, a de novo development of tumors and premature death. Biological markers of cellular senescence include the expression of lipofuscin, Ki67, p21 WAF1/Cip1 or p16 INK4a. A clinical marker of aging is the deposition of calcium salts within coronary arteries based on the Agatston score detected using multidetector computed tomography.
Conclusions. A better understanding of the cancer consequences associated with accelerated biological aging might suggest new therapeutic strategies and improve the quality of life among cancer survivors. Rehabilitation measures through changes in diet, caloric restriction, aerobic exercises and pharmacological senolytic therapy should be a part of a patient’s daily routine after completion of radical cancer treatment.

Celem artykułu jest ocena zróżnicowania przestrzennego struktury obszarowej gospodarstw ekologicznych w Polsce na poziomie regionów i gmin wraz z rozpoznaniem kierunku i tempa przemian w latach 2012–2021. Podstawę badania stanowiły dane z Głównego Inspektoratu Jakości Handlowej Artykułów Rolno-Spożywczych (GIJHARS). Przedstawiono i opisano aktualne trendy i zmiany zachodzące w strukturze wielkościowej gospodarstw ekologicznych. Stwierdzono, że ich przeciętna powierzchnia wynosi 27,5 ha i jest zróżnicowana na poziomie regionalnym, od poniżej 15 ha w województwach lubelskim, małopolskim i podkarpackim, do ponad 40 ha w dolnośląskim, lubuskim, pomorskim i zachodniopomorskim. Wykazano, że zróżnicowanie przestrzenne przeciętnej powierzchni gospodarstw ekologicznych oraz jej zmian jest zbieżne z sytuacją obserwowaną w gospodarstwach konwencjonalnych.

Celem artykułu jest analiza zapomnianego i pozbawionego znaczących artefaktów dziedzictwa kulturowego gminy Wągrowiec, a także przedstawienie pomysłów na jego rewitalizację i uatrakcyjnienie. W publikacji skupiono się przede wszystkim na dziedzictwie związanym z zakonem cystersów oraz rodem Pałuków, ograniczając analizę do obszaru Łekna, Tarnowa Pałuckiego i Bracholina oraz terenów wzdłuż rynny jezior gołaniecko-wągrowieckich. Badania były częścią projektu „Nauka przez praktykę – włączanie studentów w prace na rzecz jednostek samorządu terytorialnego” realizowanego przez studentów gospodarki przestrzennej oraz członków Koła Naukowego Zintegrowanego Planowania Rozwoju i Akademickiego Koła Naukowego Gospodarki Przestrzennej, pod opieką pracowników Wydziału Geografii Społeczno-Ekonomicznej i Gospodarki Przestrzennej UAM i przy współpracy z gminą Wągrowiec. Wyniki badań, sformułowane w trzech płaszczyznach: naukowo-poznawczej, dydaktycznej i praktycznej, wskazują, że zapomniane dziedzictwo kulturowe może być jednym z czynników rozwoju lokalnego pod warunkiem powiązania go z innymi endogenicznymi czynnikami (takimi jak atrakcyjność przyrodnicza i aktywność miejscowej społeczności), a także z inwestycjami infrastrukturalnymi, zwłaszcza w zakresie infrastruktury turystycznej i komunikacyjnej. Konieczna jest również integracja planowania rozwoju w wymiarze sektorowym i terytorialnym.
Sommerstück: On Christa Wolf’s Rediscovery of the Idyll
Authors: Beizaei Baharak
Published: June 2024

This article examines Christa Wolf's Sommerstück (1989) through the lens of modernist utopian thinking and genre-theory. The novel challenges the common-sense definition of utopia as an imagined paradisiacal state and the idyll as an idealized vision of communal harmony, complicating the question of dwelling within a utopian idyll at the specific historical conjuncture that preceded the Mauerfall. Interrogating the function of fantasy and the structure of mirage in idealized moments of crystallization with reference to Jameson’s opposition of idyll to utopia, the article contends that utopian impulses in Sommerstück aim to replace the harsh reality of East Germany through the idealization of the quotidian. Although lampooned by Hegel in the Aesthetics as lacking development and the many-sidedness of human interests evinced in epic poetry, the idyll is nonetheless positioned as the prosaic ground for romance and on a continuum with hybrid forms of epic. The article charts the temporal structure of development and progression inherent in the formalism of the genre in terms of the temporal structure of utopian striving. I first identify the temporal structure of idyll and utopia as outlined in the narrative. Of paramount importance is how the narrative, despite being rooted in a specific historical context, attempts to create a utopian vision of social relations as at once timeless and evolving. The shifting relationship between utopian ideals and a changing political reality becomes a focal point for thinking the inseparability of the idyllic from the utopian. With the fall of the Berlin Wall, anti-utopian elements of the negative ideal – the remnants of the old society of control and surveillance – were rendered more prominent to the observers of the divide. From a certain vantage point, then, one could say that the phenomenon of utopia is one of perspectival and spectatorial distance; it intersects with the idyllic mirage of a harmonious collocation in a state of innocence where different societal ideals and classes merge into indistinction. The article deepens the analysis of utopia by considering it within broader frameworks of genre-theory and German idealist thinking, suggesting that the quest for a perfect society may involve control, assimilation, and power struggles – dystopian themes highlighted by the novel when reread in light of catastrophe and a critical reevaluation of the meaning of dwelling at ‘the end of history.’

The discovery of a stone fragment from Svingerud/Hole in Norway, whose inscription is dated between 1/25 and 250 CE, attests to the early use of rūnō (cf. Zilmer/Vasshus 2023) as opposed to rūnōʀ. The plural rūnōʀ (ON rúnar) is attested on runestones of the Classical and Post-classical runic periods including C-bracteates. The paper aims to clarify whether rūnō is to be understood soberly with Morris (1985) and Antonsen (1980) as a term of everyday language ›message, inscription‹ to be distinguished from Goth. rūna ›mystery, secret, counsel‹, or rather as a term for ›secret, orally presented knowledge‹, before being linked up to the fuþark and writing in runes in the due course of its history.

Published: June 2024

Because of extreme global temperatures driven by climate change, the vulnerability of asphalt pavement to heat-induced damage has become a major concern given increasing traffic loads. Traditional asphalt binders oftentimes do not meet the demanding standards for withstanding this condition. As a result, the use of recycled plastics in asphalt road construction has gained popularity because of its potential performance improvement, sustainability, and cost-effectiveness. This study investigates the impact of recycled high-density polyethylene (rHDPE) and recycled polypropylene (rPP) on the high-temperature rheological properties of asphalt binder throughout its service life. A comprehensive evaluation was conducted to assess the rutting resistance, elastic response, deformability, stress sensitivity, and aging susceptibility of modified binders at high temperature. The findings reveal that the addition of rHDPE and rPP to asphalt binders enhances rutting resistance, as evidenced by improved rutting parameters and rutting failure temperatures. The analysis of nonrecoverable creep compliance and percent recovery also showed improvement in elasticity and resistance to permanent deformation of the modified asphalt. Although rHDPE and rPP-modified asphalt did not meet the criteria for elastomeric polymers, a trend toward improved elastic response was observed with aging. Additionally, the result of the aging index showed that though increased stiffness is observed as asphalt-aged, rPP-modified asphalt is more susceptible to short-term aging but exhibits more stable performance during service life compared with the rHDPE-modified asphalt.
The Granular Retrosplenial Cortex Is Necessary in Male Rats for Object-Location Associative Learning and Memory, But Not Spatial Working Memory or Visual Discrimination and Reversal, in the Touchscreen Operant Chamber

The retrosplenial cortex (RSC) is a hub of diverse afferent and efferent projections thought to be involved in associative learning. RSC shows early pathology in mild cognitive impairment and Alzheimer's disease (AD), which impairs associative learning. To understand and develop therapies for diseases such as AD, animal models are essential. Given the importance of human RSC in object-location associative learning and the success of object-location associative paradigms in human studies and in the clinic, it would be of considerable value to establish a translational model of object-location learning for the rodent. For this reason, we sought to test the role of RSC in object-location learning in male rats using the object-location paired-associates learning (PAL) touchscreen task. First, increased cFos immunoreactivity was observed in granular RSC following PAL training when compared with extended pretraining controls. Following this, RSC lesions following PAL acquisition were used to explore the necessity of the RSC in object-location associative learning and memory and two tasks involving only one modality: trial-unique nonmatching-to-location for spatial working memory and pairwise visual discrimination/reversal. RSC lesions impaired both memory for learned paired-associates and learning of new object-location associations but did not affect performance in either the spatial or visual single-modality tasks. These findings provide evidence that RSC is necessary for object-location learning and less so for learning and memory involving the individual modalities therein.

Published: June 2024

[Objective] This study seeks to characterize mathematical tasks assessed in exams, with a focus on didactic features related to the meaning of the mathematical content they address, and their cognitive aspects. Additionally, it aims to describe the evolution of these features over time. [Methodology] In this longitudinal descriptive study, a content analysis of 568 mathematical tasks from 51 exams was conducted over 17 consecutive academic periods between 2014 and 2022. The analysis was conducted within the context of a Differential and Integral Calculus course taught at a university in Costa Rica. Information was organized and interpreted using a system of seven variables related to didactic features specific to the analysis of school-level mathematical tasks. [Results] The assessed mathematical tasks stand out for their variety of content and a predominance of verbal-symbolic representation, exclusively mathematical scientific situations, and cognitive demand at the level of procedures without connections. The predominance of exclusively mathematical scientific situations remained constant over time. However, from a certain point onwards, there was a tendency for verbal-symbolic representation and procedures without connections to decrease in favor of multiple representations and procedures with connections. [Conclusions] The assessed mathematical tasks partially reflect features related to the meaning of mathematical content and cognitive aspects essential for learning calculus. The evolution over time indicates progress in several features, although there is still ample room for improvement in others.

[Objective] The teaching of quantification tends to focus on formulas for quantifying the measurement of geometric magnitudes, ignoring their uses in other disciplines. This makes it essential to formulate reference frameworks that allow such teaching to meet the functional justifications demanded by other domains of knowledge. For this reason, and within the framework of socioepistemology, the aim of this research was to formulate an epistemology of the uses of quantification. [Methodology] The methodology was qualitative and consisted of a theoretical-methodological corpus that articulated constructs of a modelling category with empirical data. This formulation was carried out in two phases. In the first one, an epistemology was hypothetically formulated based on an analysis of resignification of the uses of quantification constructed in two specific measurement situations: one specific to an interdisciplinary community, and the other to the mathematical work entitled Intégrale, Longueur, Aire. The second phase analyzed the emergence of a resignification of the uses of quantification by engineering students during the development of a school situation designed on the basis of hypothetical epistemology. [Results] This emergence made it possible to empirically validate this epistemology and to express a transversality of uses of quantification in specific measurement situations, made up of meanings, procedures and instruments that together can be used to derive quantification arguments. [Conclusions] This epistemology of uses makes it possible to capture the measurement situation as an educational reference to establish the use, resignification, and transversality of quantification.

Published: June 2024

[Objective] Trypanosoma cruzi, a causal agent of Chagas’ disease, is a parasite whose life cycle alternates between an invertebrate (triatomine) and a vertebrate (mammal) host. Various studies have shown that in T. cruzi, HSP83 (a homolog of HSP90) is essential for cell division and control of the response to thermal stress. This investigation focused on studying the cloning, bioinformatic characterization, and expression of the heat shock protein HSP83 T. cruzi gene for further cell signaling studies. [Methodology] RNA was extracted from T. cruzi epimastigotes (EPm6 clone, MHOM/VE/2007/ 6c) using a commercial kit. The cDNA encoding HSP83 was determined using RT-PCR on extracted mRNA, for which the primers were designed based on the HSP83 sequence of T. cruzi strain CL Brener. Cloning was performed using pGEM®T-Easy and subcloned into the expression vector pQE30. Sequence and bioinformatic characterization were performed. The gene was expressed, and the recombinant protein was purified using affinity chromatography and identified through immunoblotting. [Results] Sequence analysis showed similarity to the gene encoding HSP83 from Trypanosoma cruzi, and HSP domains and B epitopes in the sequence were also observed. After 3 hours of induction with IPTG, a recombinant protein with an approximate weight of 83 kDa was obtained. The immunoblotting reaction with hyperimmune anti-T. cruzi epimastigote serum helped detect a single band with a molecular weight of nearly 83 kDa. [Conclusions] All results indicate that the cloning and characterization of HSP83 from Trypanosoma cruzi was achieved.

Published: June 2024

[Objective] The objective of this investigation was to analyze the composition of birds associated with organic cocoa (Theobroma cacao) crops managed under 3 different types of tree cover. [Methodology] Three census points were established in each farm to record all birds observed and heard in 5-minute sample periods. Counts were conducted in triplicate, both in the early morning and at dusk. Differences in avifauna composition between farms were analyzed using the ANOSIM test. Abundances were transformed using the Decostand function and the Hellinger method in the R-Vegan statistical package. Analysis of clustering of species among plantations was performed using non-metric multidimensional scaling (nMDS) and the Bray-Curtis index. Contribution of species to the dissimilarity between groups was analyzed with the SIMPER module. Statistically significant differences were considered when P ≤ 0.05. [Results] Four hundred and twenty-eight individuals were observed, and classified into 49 species and 23 families. The farms where cocoa plants grow in shadier conditions due to canopy development showed a higher number of species (34) and individuals (146). Bird composition varied significantly between farms (F (1,8) = 3.22; P < 0.02). The mean abundance of 19 species (39.6%) showed significant differences (P < 0.05) when comparing the farms with the most and least shade. [Conclusion] Bird composition is more complex on organic cocoa farms, which have more developed canopies and are near regenerating forests.

[Objective] Genetic literacy relates to knowledge and skills in utilizing genetic principles for solving various problems or issues related to genetics. Genetic literacy is an essential ability for students to master, as it is related to various current issues, especially in the fields of health and agriculture. However, research on genetic literacy has not been properly developed from different perspectives, including those related to academic level and gender. Therefore, to fill this gap, the present research seeks to measure the genetic literacy of Indonesian high school students in relation to their academic level and gender. [Methodology] Data were collected using an analytic observational cross-sectional study. The research participants were 1102 students from 55 senior high schools in Indonesia. The participants took a test, which had been evaluated for validity and reliability. The data was then analyzed using ANOVA, and the participants’ genetic literacy levels were categorized as adequate or inadequate. [Results]. The study showed that students’ genetic literacy was relatively inadequate. While academic level was significantly related to students’ genetic literacy, gender was not. [Conclusions] The results of this study indicate that the academic level has a significant effect on the level of students’ genetic literacy, while gender does not. The findings support the conclusion that genetic literacy needs to be considered in education, and that it is necessary that teachers and schools design appropriate strategies to empower and increase students’ genetic literacy in high school settings.
