El proyecto Círculo Virtuoso de la ciudad de Pereira, Colombia, como una iniciativa transformadora del territorio
Authors: Marín-Montoya Martha Liliana
Published: March 2024

El proyecto Círculo Virtuoso (CV), de la ciudad de Pereira, busca la transformación del territorio y el desarrollo socioeconómico de la ciudad a través de la promoción de una sociedad productiva y equitativa basada en el conocimiento. Ideado en el 2012 por la Oficina de Planeación de la Universidad Tecnológica de Pereira, el CV integra ciclos vitales con ciclos productivos, estructurado bajo tres componentes (salud sensorial, psicosocial y pedagógico), distribuidos en cinco eslabones (jardín, colegio, universidad, red de nodos, y comunidades innovadoras) que, articulados entre sí, y de manera secuencial, prometen alcanzar «la sociedad deseada». A pesar de haber sido catalogado tan solo como un proyecto educativo durante sus diez años de implementación, su motivación e implementación, así como su alto nivel de inclusión de actores múltiples provenientes de diferentes sistemas sociotécnicos, presenta matices de instrumento de política de innovación local con visión sistémica. Dichos elementos, poco tradicionales en iniciativas de ciudad, unidos a características particulares del CV que modifican paradigmas del desarrollo territorial, logran alinearse con lo propuesto por el marco de políticas de innovación transformativa. Siendo el CV un instrumento de planeación con limitados intentos de evaluación y análisis de impacto, la aplicación de la herramienta Radar: 7 principios de innovación transformativa es la oportunidad para denotar que la creación de narrativas transformadoras, el desarrollo de planes de evaluación formativa y la implementación de gobernanzas horizontales son elementos indispensables en instrumentos de desarrollo que, como el CV, pretenden transformar el territorio.
Understanding dis-adoption of technologies by smallholder dairy farmers in Indonesia
Authors: Akzar Rida , Peralta Alexandra , Umberger Wendy
Published: March 2024

Farmer cooperatives represent a vertical coordination strategy aimed at reducing transaction costs and facilitating the adoption of technologies among farmers. In their roles, cooperatives undertake internal coordination of activities which may include enforcement measures, provision of quality inputs, internal control, and negotiation of favourable terms of exchange with buyers. However, limited attention has been given to understanding how cooperatives’ performance in the internal coordination of activities either promotes or hinders the continued adoption of agricultural technologies among cooperative members. We conducted a case study of the dairy sector in West Java, Indonesia, and utilised a mixed-method approach combining insight from dairy cooperative board members and dairy farming households. Our results suggest that the dis-adoption of dairy technologies is rooted in weak or non-existent monitoring and enforcement mechanisms to ensure input and output quality, the absence of price incentives, and inadequate provision of extension services. Furthermore, the lack of tight monitoring and control mechanisms reduces the cooperatives’ bargaining power with input providers and milk buyers. Unless these issues within the cooperatives are addressed, continued adoption of recommended dairy farming practices by smallholder farmers will not be sustained.
THE EFL PRE-SERVICE TEACHERS' PERSPECTIVES AND EXPECTATIONS TOWARDS MICROTEACHING: A CASE STUDY AT AN ENGLISH DEPARTMENT, IN A PUBLIC UNIVERSITY
Authors: Aslamia RTS. Suaibatul
Published: March 2024

Teaching practice in real educational environment is an obligation course for student teacher of teacher training and education faculty. This course is believed to be very significant as authentic experience to create professional educator by training. However, student teacher has to follow microteaching program before teaching practice at school as a set of teaching practice preparation (Ismail, 2011) which provided by university to be qualified pre-service teacher. This study was conducted as qualitative research with a case study approach. It was commonly used to understand peoples' experiences and to express their perspectives (Creswell, 1994). Furthermore, this study used triangulation data sources, consisting of: (1) demographic questionnaire, (2) face-to-face interview, and (3) observation that consisted of video as visual data, to conduct high quality research with an excellent way (Christensen & Johnson, 2008). The first, microteaching gave knowledge about teaching technical steps. This finding was relevant with another research that microteaching provided and developed knowledge of methodological teaching skill (Sen, 2009). However, findings in this study provided very specific technical teaching skill that gained by EFL pre-service teachers during the implementation of microteaching, such as a teacher should design lesson plan before coming to class, besides on lesson plan they had to pay attention with several points like material that would be taught and then decided appropriate steps in teaching that material to student on accurate time allocation. Second, the advantages of microteaching were teaching practice which gave opportunities to smoothness pre-service teachers' teaching skill (Ismail, 2011) which been the most important point of microteaching itself. However, not only well preparation that needed by EFL pre-service teachers to be an educator, but also well teaching was also significant.
The Antinomy Between Fictionality and Authenticity in The World According to Garp by John Irving
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Beshenkova Tatevik A.
Published: March 2024

The article examines the antinomy between fictionality and authenticity in The World According to Garp by John Irving. The first part of this article deals with the narrator of the framing text, who constantly shifts from pure imagination to meticulous fixation on pseudo-documental facts about the fictionalized character Garp. The mode of narration in terms of adhering to factuality and imagination alters in different parts of the novel. The ambiguity of the narrator’s position and its inclusion in the considered novel’s antinomy result in the possibility of attributing the novel’s framing text to either Garp himself or his official biographer, Donald Whitcomb. Further, the article examines interpolated texts attributed to the secondary narrator (Garp), in which he tries to find a balance between pure fantasy and reliance on memory in his work. Garp’s fiction here divides into three major groups: memory and personal experience based, imaginative, and a combination of the two, of which the latter proved to be the most fruitful. The article describes how the relationship of the primary and secondary narrators with conventional “reality” is complicated by comparing the frame text and texts attributed to the character, as well as the latter with the works of the biographical author (i. e. Irving). The final part of the article exposes the lyric poetry as a synthesis of (auto)biographical (e. g. “Sexual Suspect” by Jenny Fields, character’s mother) and fictionalized (Garp’s works). The antinomy of fictionality and authenticity helps raise questions about authenticity in art, “high” and “low” literature, and the nature of art and creativity.
“You Are New, I Am Old”: Handwritten Drafts of A.S. Suvorin’s Letters to D.S. Merezhkovsky (1901–1911)
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Andrushchenko Elena A.
Published: March 2024

This work is the first to introduce handwritten drafts of the letters of A.S. Suvorin (1834–1912), owner and publisher of the “Novoye vremya” newspaper, to D.S. Merezhkovsky. The letters, which remained in the newspaper’s archive, cover the period from 1901 to 1911 and can explain the reasons for Suvorin’s interest in the young writer. Merezhkovsky was one of the objects of his passion for talented people, which was recalled by contemporaries and which explains his relationship, in particular, with Anton Chekhov. Suvorin’s letters to Merezhkovsky express his views as a critic, publisher, and theater owner, exhibiting an awareness of circumstances, business sense, and broad knowledge. Appearing as a representative of the “old” literature, he showed a keen perception of the aspirations of the “new” one. Suvorin attempted to hold Merezhkovsky back from an ill-timed publication of his letter to “Novoye vremya” about L. Tolstoy (1901). He also made detailed comments about the drama “Paul I” and reacted sharply to Merezhkovsky’s quoting of his words in the article “Nationalism and Religion” (1911). Attempts to patronize Merezhkovsky and support his endeavors concluded in a conflict with him towards the end of Suvorin’s life. The publication of handwritten drafts of Suvorin’s letters fills certain gaps in the notions about his contacts with the Merezhkovskys. Suvorin’s correspondence also illuminates his personal features and helps to restore the details of the literary life in the first decade of the 20th century.
A.P. Platonov and V.P. Stavsky (New Materials to the Writer’s Biography)
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Osipenko Maria V.
Published: March 2024

For the first time, the article examines the role of V.P. Stavsky, the Secretary of the Union of Soviet Writers, in the biography of A.P. Platonov during the 1930s. The study of previously known facts about Stavsky’s favorable response to Platonov’s short story “Immortality” (“Bessmertie,” 1936) in a broader context, together with the new materials, allows reconsidering the established notion of an episodic role of Stavsky in the writer’s fate. The support of the Secretary of the Writers’ Union (behind which possibly stood Stalin himself) provided Platonov with an official place among the best Soviet writers in 1936–1937. His work was declared a benchmark for the authors of the literary works collections of the state. His name sounded among the representatives of the new generation of literary leaders of the country. He was entrusted with new projects with the support of the Writers’ Union. At the same time, it was Stavsky’s support that triggered the largest wave of critical attention toward Platonov since the publication of “For Future Use” (“Vprok”), which led to the following persecution of the writer. Most of the archival materials in this article are published for the first time. The article introduces new biographical facts about A. Platonov and V. Stavsky.
Georgij Breitburd and Soviet Reception of Italian Neo-Avant-Garde
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Golubtsova Anastasia V.
Published: March 2024

The article analyzes the Soviet reception of Italian Neo-Avant-Garde (Group 63), including the contribution by Georgij Breitburd, translator, consultant on Italian literature at the Foreign Commission of the Union of Soviet Writers, one of the key figures in Soviet-Italian cultural relations. The study focuses on the focal episode of Neo-Avant-Garde polemics, that is, on Breitburd’s article in “Novy Mir” (March 1967) dedicated to Group 63 and on Italian discussion around it, which took place mainly in left-wing periodicals, like newspaper “Unità,” magazines “Rinascita” and “Quindici,” but also in moderate and center-right newspapers “Il Messaggero” and “La Discussione.” The article proves that Breitburd played a crucial role in the Soviet reception of Italian Neo-Avant-Garde. It was his article in “Novy Mir” that made possible profound and academically correct discussions around this movement in “Inostrannaya Literatura” and “Voprosy Literatury.” Breitburd’s ideological fight against Group 63 in the late 1960s and early 1970s paradoxically increased the popularity of the movement in the USSR. After Breitburd died and the fight stopped, Italian Neo-Avant-Garde literature was nearly forgotten by Soviet critics and researchers and now, in modern Russia, is known only to a narrow circle of specialists. Most of Neo-Avant-Garde fiction was not translated and published either in Soviet or in post-Soviet times and still remains practically unavailable to Russian-speaking readers.

How do corporate governance, artificial intelligence, and innovation interact? Findings from different industries
Authors: Gouiaa Raef , Huang Run
Published: March 2024

Research in the field of corporate governance has been exhaustive, and recently many scholars have focused on the relationship between corporate governance attributes and artificial intelligence (AI), corporate governance attributes, and corporate innovation (Asensio-López et al., 2019), however, there are few studies that combine corporate governance, AI, and corporate innovation. This article examines the relationships among corporate governance attributes, AI, and corporate innovation. Adopting a new perspective, we have tried to help resolve this issue using a content-analysis that integrates data from over 50 companies that trade on National Association of Securities Dealers Automated Quotations (NASDAQ) to analyze the relationship between board attributes, the practice of AI and firm innovation for the time 2018–2022. The results suggest that particular aspects of boards, such as board size, board diversity, and ownership concentration show significant correlations with firm AI development and innovation for overall industries, but the levels of associations also vary depending on different innovation measurements and samples considered in specific industries. Corporate governance has more significant variables in the manufacturing and information technology service industries. Moreover, the mediating effects of AI and innovation are examined, respectively. This research offers implications to corporate decision-makers as to how to proceed if the intent is to offer commercialized AI advancements and successful breakthrough innovations.

Published: March 2024

An unparalleled copper(I)-catalyzed synthesis of 1,3,4-oxadiazoles from
tertiary amines in one step has been described. The one-pot reactions
involving (N-isocyanimine)triphenylphosphorane , tertiary amines , and
carboxylic acids resulted in the formation of 1,3,4-oxadiazoles in
moderate to good yields through a consecutive oxidative Ugi/aza-Wittig
reaction, enabling direct functionalization of sp3 C-H bonds adjacent to
the nitrogen atom. This method offered several notable advantages,
including mild reaction conditions, ligands free, exceptional
productivity and high functional group tolerance. The preliminary
biological evaluation demonstrated that compound 4f inhibited hepatoma
cells efficiently, suggesting potentially broad applications of the
approach for synthesis and medicinal chemistry.

Published: March 2024

Puerto Rico harbors a diverse vertebrate fauna with high levels of
endemism. However, while several books for vertebrate diversity and
local checklists for birds have been published, checklists of
amphibians, reptiles, and bats are lacking or nonexistent at both local
and regional scales. In this study, we documented the amphibian,
reptile, and bat faunas at Mata de Plátano Field Station and Nature
Reserve, in Arecibo, Puerto Rico. We document four species of
amphibians, seven lizards, three snakes, and nine bats. Despite prior
works using samples from this nature reserve, this represents the first
vertebrate checklist for the Mata de Plátano Field Station and Nature
Reserve. We provide additional natural history observations based on our
survey results and highlight the importance of including local and
regional checklists of species for downstream research and conservation.

Published: March 2024

Phytochemical studies on the leaves and twigs of Garcinia oligantha led
to the isolation of twelve novel depsidone derivatives
(oli-ganthdepsidones A-L, 1-12). Their structures were elucidated by
extensive spectroscopic analysis including 1H and 13C NMR, HSQC, HMBC
and NOESY along with HRESIMS. The structure of oliganthdepsidone J was
finally determined using DFT-NMR chemical shift calculations and DP4+
methods. Cytotoxicity test in four human cancer cell lines indicated
that oliganthdepsidone F (6) had relatively strong cytotoxic effect
against A375 (melanoma), A549 (lung cancer), HepG2 (liver cancer), and
MCF-7 (breast cancer) cell lines with IC50 of 18.71, 15.44, 10.92, and
15.90 μM, respectively. The dose- and time-dependent antiproliferative
effects of oliganthdepsidone F on these cell lines were also observed by
CCK-8 test. As determined by fluorescent microscopy and flow cytometry
in these cell lines, oliganthdepsidone F could promote cell apoptosis,
leading to the inhibition of cell proliferation. The results of wound
healing assay and transwell assay showed that oliganthdepsidone F could
inhibit the migration and invasion of A549 and MCF-7 cell lines in a
concentra-tion-dependent manner.
Resilient Data-Driven Asymmetric Bipartite Consensus for Nonlinear Multi-Agent Systems against DoS Attacks
Authors: Zhang Yi , Wang Yichao , Zhao Junbo , Zuo Shan
Published: March 2024

In this article, we study an unified resilient asymmetric bipartite
consensus (URABC) problem for nonlinear multi-agent systems with both
cooperative and antagonistic interactions under denial-of-service (DoS)
attacks. We first prove that the URABC problem is solved by stabilizing
the neighborhood asymmetric bipartite consensus error. Then, we develop
a distributed compact form dynamic linearization method to linearize the
neighborhood asymmetric bipartite consensus error. By using an attack
compensation mechanism to eliminate the adverse effects of DoS attacks
and an extended discrete state observer to enhance the robustness
against unknown dynamics, we finally propose a distributed resilient
model-free adaptive control algorithm to solve the URABC problem. A
numerical example validates the proposed results.
The Impact of Storytelling about Local Cultural Heritage on City Attractiveness, Place Identity, and Loyalty: Focusing on Cultural Heritage Tourists in the Gongju Area
Authors:   The Convergence Tourism Contents Society, Cheon Deok-Hee , Kim Sang-Hun
Published: March 2024

Purpose: Cultural heritage tourism is different from general tourism, so you can properly understand the cultural heritage when there is explanation through storytelling. Therefore, in this study, we aim to empirically study how cultural interpreters' storytelling about Gongju City's cultural heritage affects the city attractiveness, place identity, and loyalty perceived by tourists visiting Gongju City.
Methods: For the empirical study, a survey was conducted on tourists who visited Gongsanseong Fortress and King Muryeong's Tomb, which are cultural heritage sites in the Gongju region, and experienced storytelling by cultural interpreters. A total of 182 questionnaires were used for empirical analysis.
Results: As a result of factor analysis, storytelling was divided into education, interestingness, sensitivities, and theme nature categories, and city attractiveness, place identity, and loyalty were each classified into a single dimension. As a result of the hypothesis testing, it was found that among the components of storytelling, interestingness, sensitivities, and theme nature had a similar degree of influence on city attractiveness, while education had a somewhat lower influence. In addition, education had the highest influence on place identity, while interestingness, sensitivities, and theme nature had a lower influence than education.
Conclusion: In the end, research has shown that storytelling about cultural heritage can increase city attractiveness, place identity, and loyalty.
Preparation of magnetic surface molecularly imprinting polymers based on glycidyl methacrylate as selective sorbents for aniline removal from aqueous medium
Authors: Tadic Tamara , Vukovic Zorica , Pavlovic Vladimir , Nastasovic Aleksandra , Onjia Antonije , Markovic Bojana
Published: March 2024

In this paper, two molecularly imprinted polymers (MIPs) based on glycidyl
methacrylate were synthesized by radical suspension polymerization and
surface imprinting method in the presence of silica-coated magnetic
nanoparticles. Ethylenediamine (eda) and triethylentetramine (teta) were
used for surface imprinting. The samples were characterized by Fourier
transform infrared spectroscopy (FTIR), scanning electron microscopy with
energy-dispersive X-ray spectroscopy (SEM-EDS), and mercury porosimetry. The
sorption and desorption behaviors of two MIPs as an aniline sorbent from
aqueous solutions were evaluated. Sorption studies were carried out in the
pH range of 2.0 - 10.0, and maximum sorption capacities were attained at pH
6.0. Also, the effect of different desorption agents were examined and
acetonitrile was chosen as the best desorbing eluent for aniline. The
obtained MIPs were regenerated in four sorption/desorption cycles, and the
results show that these two MIPs could be reusable as sorbents for removing
aniline from polluted wastewater.
The tomb of Queen Theodora at the Banjska Monastery - another reexamination
Authors: Popovic Danica
Published: March 2024

The paper explores the problem of the tomb of Queen Theodora, the first wife
of King Stefan Decanski and mother of King and later Emperor Stefan Dusan,
at the Banjska Monastery, a foundation of King Stefan Uros II Milutin. The
tomb is the main topic of the charter King Dusan issued to this monastery.
The paper minutely examines the previous research on the subject, including
different identifications of the personages buried at Banjska. Special
attention was accorded to the analysis of new sources, written and material,
relevant to this problem. The author concludes that the transfer of Queen
Theodora?s remains to Banjska, on the orders of King Dusan, was an
ideologically motivated move. The tomb on the north side of the west bay is
identified as Theodora?s. The author cautiously proposes that Konstantin,
King Milutin?s younger son, might have also been interred at Banjska, in the
north parekklesion along the narthex. The funerary program of Banjska is
assessed from the perspective of traditional solutions and the reception of
new models adopted from Byzantium.
Ever ready throne: Reassessing the role of hetoimasia in the church of the virgin Eleousa in Veljusa
Authors: Milanovic Ljubomir
Published: March 2024

The Church of the Virgin Eleousa in Veljusa was commissioned by the former
bishop of Tiberioupolis (Strumica), monk Manuel. In the narthex, under the
arcosolium adjacent to the south wall, a brick grave was discovered by
archaeologists. According to the finds, the construction of the grave was
inseparable from the southern wall, thus indicates that the monk Manuel
commissioned a tomb establishing a place of his eternal rest. The original
painting executed between 1085 and 1093 is best preserved in the sanctuary
along with fragmentary portions in the naos and the south subsidiary chapel.
An enthroned Virgin and Child decorates the altar area in the main apsidal
conche. Below is the unusual composition of the Officiating bishops. Four
church fathers surround the throne, hetoimasia on which are placed a Gospel,
a cross, which is flanked by instruments of torture, and the dove of the
Holy Spirit. Scholars have explained the unique representation of hetoimasia
within the scene of Officiating Bishops through its liturgical symbolism.
What has been neglected in the case of Veljusa, however, is the elucidation
of another symbolic meaning of the depiction of hetoimasia, namely its
soteriological-eschatological role connected with a possible function of the
church as a burial place of the monastery founder. This paper will shed a
light to the problem of eschatological nature of hetoimasia in the context
of the burial place of monk Manuel in Veljusa.
Hagios germanos of prespa, a church and a patriarch after the other
Authors: Angelidi Christine
Published: March 2024

The study of the middle Byzantine church of Saint Germanos is a good example
of the complicated relations in the south of the Balkan Peninsula during the
era of national allegiances and their impact on earlier and current
scholarship. The founding of the church, its architecture and iconography
have been studied through various lenses, but a comprehensive approach has
yet to appear. The paper does neither intend to fill these gaps nor to
investigate new archeological material or provide definitive solutions to
the puzzling history of the monument, which, until recently, functioned
within culturally and linguistically diverse communities. Instead, it
proposes a re-reading of the visual and written evidence, in dialogue with
the comments and interpretations that have so far been published. Moreover,
the monument?s iconography and the issue of its patron saint are tentatively
contextualized.
A legal-historical contribution to the research of the office of praetor in Byzantium
Authors: Ilic Tamara
Published: March 2024

The office of praetor in Byzantium represents a vestige of antiquity revived in the middle years of the reign of Justinian I. The paper offers a history of the function following the chronological timeline, as well as an analysis of the praetor?s competences in the judicial and administrative spheres. Firstly, relying on the few available sources up to the 10th century, it brings an overview of the praetor?s competences. In the 10th century, the praetor became a thematic judge, the supreme civil officer in the province, outranking the strategos, which is how most sources portray the praetor in the 11th and 12th centuries. The paper examines the praetor?s service in law and juxtaposes it with his authority as the supreme figure in the province. Simultaneously, in the 11th century, the praetor was part of the capital?s judiciary system, with a possible scope of duties in private law. The last known sources describe the praetor as the court?s official in contacts with the Latins.
The peculiarities of the Byzantine provincial administration in the Balkans under the Komnenoi
Authors: Cvetkovic Milos
Published: March 2024

The text presents the results of the research on the Byzantine provincial
organization in the parts of the Balkans that the Empire directly controlled
during the Komnenian era. The non-uniform historical and political evolution
of some regions of the Balkan Peninsula called for different methods to be
employed by the Constantinopolitan court when organizing the local
provincial administration, leading to a differentiation among the Balkan
themes. Another factor that contributed to the differentiation process was
that not all provinces were of equal importance to the Empire, which is why
strategically important districts and their local elites received certain
privileges, mostly of a fiscal and financial nature. The role and
significance of some themes grew over time, while others gradually lost
their strategic relevance. That was reflected in Constantinople?s changing
approach to organizing the provincial administration in the Balkans. This
contribution focuses on when, how, and why some Balkan districts received
privileges or had them rescinded in the Komnenian era.

This study compared the effects of a low-fat vegan diet to those of a portion-controlled diet in people with type 1 diabetes. Over 12 weeks, the average total daily dose of insulin decreased significantly and insulin sensitivity increased significantly in the vegan group, while no significant changes were observed in the group receiving the portion-controlled diet. Total and LDL cholesterol decreased in the vegan group, as did the ratio of blood urea nitrogen to creatinine. A1C decreased in both groups. These findings suggest that a low-fat vegan diet may yield improvements in insulin sensitivity, insulin requirements, glycemic control, and markers of cardiovascular and renal health compared with a portion-controlled diet in people with type 1 diabetes.

Published: March 2024

OBJECTIVE

Tubulointerstitial injury contributes to diabetic kidney disease (DKD) progression. We tested tubular biomarker associations with DKD development in type 1 diabetes (T1D).

RESEARCH DESIGN AND METHODS

We performed a case-cohort study examining associations of tubular biomarkers, measured across seven time points spanning ∼30 years, with incident macroalbuminuria (“severely elevated albuminuria,” urinary albumin excretion rate [AER] ≥300 mg/day) and sustained low estimated glomerular filtration rate (eGFR) (persistent eGFR <60 mL/min/1.73 m2) in the Diabetes Control and Complications Trial (DCCT)/Epidemiology of Diabetes Interventions and Complications (EDIC) study. Biomarkers included KIM-1 and sTNFR1 in serum/plasma, MCP-1 and EGF in urine, and a composite tubular secretion score reflecting secreted solute clearance. We assessed biomarkers using single values, as mean values from consecutive time points, and as change over consecutive time points, each as time-updated exposures.

RESULTS

At baseline, mean diabetes duration was 5.9 years, with mean HbA1c 8.9%, eGFR 125 mL/min/1.73 m2, and AER 16 mg/day. There were 4.8 and 3.5 cases per 1,000 person-years of macroalbuminuria and low eGFR, respectively. Assessed according to single biomarker values, KIM-1 was associated with risk of subsequent macroalbuminuria and low eGFR (hazard ratio [HR] per 20% higher biomarker 1.11 [95% CI 1.06, 1.16] and 1.12 [1.04, 1.21], respectively) and sTNFR1 was associated with subsequent macroalbuminuria (1.14 [1.03, 1.25]). Mean KIM-1 and EGF–to–MCP-1 ratio were associated with subsequent low eGFR. In slope analyses, increases in KIM-1 and sTNFR1 were associated with subsequent macroalbuminuria (per 20% biomarker increase, HR 1.81 [1.40, 2.34] and 1.95 [1.18, 3.21]) and low eGFR (2.26 [1.65, 3.09] and 2.94 [1.39, 6.23]).

CONCLUSIONS

Serial KIM-1 and sTNFR1 are associated with incident macroalbuminuria and sustained low eGFR in T1D.
Discontinuation of Fumaric Acid Esters is Affected by Depressive Symptomatology: A Retrospective Analysis
Authors: Krefting Frederik , Hölsken Stefanie , Schedlowski Manfred , Sondermann Wiebke
Published: March 2024

Fumaric acid esters (FAEs) remain a widespread therapy option for moderate-to-severe psoriasis. However, drug survival of FAEs is limited by adverse events (AEs) or inadequate treatment response. Depressive disturbances are highly prevalent in psoriasis patients and are hypothesized to be associated with the reporting of AEs and therapy discontinuation. This study’s aim was to analyze whether psoriasis patients with comorbid depressive symptomatology are more likely to discontinue treatment with FAEs due to AEs and/or inadequate treatment response. Data were retrospectively extracted from the records of patients starting therapy with FAEs in the Department of Dermatology, University Hospital Essen, Germany between 2017 and 2022, covering the first 52 weeks of treatment. Psoriasis severity and depressive symptomatology, as well as AEs and therapy discontinuation, were analyzed. Psoriasis patients (N = 95, 47.37% female) with depressive symptomatology (42.11%) were more likely to discontinue therapy due to patient-reported AEs, while the total number of reported AEs was not associated with depression. The results support the hypothesis that among psoriasis patients with depressive symptoms, the associated introspection and somatization may result in increased sensitivity for AEs and thus in quicker therapy discontinuation. In these patients, the occurrence of nocebo effects should be minimized, e.g. by special communication techniques.

Since December 2019, the COVID-19 pandemic has profoundly affected healthcare. The real effects of the COVID-19 pandemic on skin cancer are still unclear, more than 3 years later. This study aims to summarise the pandemic’s impact on skin cancer diagnosis and outcome. A systematic review and meta-analysis was conducted, selecting studies comparing skin cancer diagnosis and prognosis post-pandemic with pre-pandemic data. A total of 27 papers were reviewed including 102,263 melanomas and 271,483 keratinocyte carcinomas. During the initial pandemic months (January–July 2020), melanoma surgeries dropped by 29.7% and keratinocyte carcinomas surgeries by 50.8%. Early pandemic tumours exhibited greater thickness and stage. In a long-term period beyond the initial months, melanoma surgeries decreased by 9.3%, keratinocyte carcinomas by 16.6%. No significant differences were observed in the Breslow thickness of melanomas after the start of the pandemic (mean difference 0.06, 95% confidence interval –0.46, 0.58). Melanomas operated on post-pandemic onset had an increased risk of ulceration (odds ratio 1.35, 95% confidence interval 1.22–1.50). Keratinocyte carcinomas showed increased thickness and worsened stage post-pandemic. However, studies included were mostly retrospective and cross-sectional, reporting diverse data. This review indicates that the pandemic likely caused delays in skin cancer diagnosis and treatment, potentially impacting patient outcomes.

The mobility sector is considered a major contributor to global greenhouse gas emissions and air pollution. As a result, many countries have initiated the transition from fossil fuel-powered to electrified powertrains. This transformation of the powertrain concept will lead to a rapid increase in the production of electric vehicles and, therefore, to a high demand for so-called traction batteries. As a production step of the traction batteries, a connection between the cell connector and the terminal of the battery cell has to be manufactured. For this purpose, laser beam welding is a reliable and efficient joining technique. In order to ensure continuous quality of the welding process during production and to detect defects in real time, reliable process monitoring is required. In this study, spectral and acoustic emissions during laser beam welding were recorded using a laser welding monitor and an optical microphone. For determining possible correlations between the signals and weld defects, various failure cases were generated by the systematic placement of disturbance elements. These elements included a contaminated surface, a gap between the cell connector and the battery cell, and a misalignment of the cell connector. Based on the recorded signals, statistical metrics were calculated. Finally, weld seams with and without defects were compared to assess the capability of both sensor systems for detecting the weld defects.

A taxonomic study of the genus Trachelomonas (Euglenophyta) was undertaken in temporary ponds on Menorca Island, Spain, called “basses”. Among the 13 studied ponds, this genus was found in only one, called Verda B. A light and scanning electron microscope study of the samples taken from this body enabled the identification of 28 taxa, 26 of which were documented by SEM micrographs, including different views and details of the lorica. All the taxa described are reported as new for this region, while 18 are new for Spain. T. granulosa var. crenulatocollis, T. nigra, T. pseudofelix, and T. raciborskii var. nova f. minor are examined and photographed by SEM for the first time. T. duquei var. minor is proposed as a new variety.
A Mini Review on Current Challenges and Opportunities in the Management of Bovine Mastitis
Authors: PR Bhatt
Published: March 2024

Bovine subclinical mastitis stands out as a significant challenge in the dairy industry, leading to substantial milk losses. The issue becomes more alarming as lactating cows frequently face severe infections caused by Staphylococcus aureus bacteria, resulting in detrimental udder damage. The conventional approach of combating such infections involves prolonged antibiotic treatments, contributing to the emergence of Antimicrobial Resistance (AMR) in cows. Compounding the issue, S. aureus bacteria can undergo modifications, transforming into the formidable Methicillin-Resistant S. aureus (MRSA). Addressing this pressing concern requires exploring alternative solutions, and one promising avenue lies in the realm of medicinal plants. Leveraging the inherent antibacterial properties of phytochemicals found in various medicinal plants could offer a sustainable and effective approach to managing bovine mastitis. Not only do these botanical remedies provide a potential solution to the challenges posed by conventional antibiotic treatments, but they also offer a more environmentally friendly and holistic approach to safeguarding the health of dairy cows and preserving milk production in the industry.

Researchers are increasingly investigating marketing assertions related to natural products and supplements. In the modern era, the study of bioavailability has gained prominence as a burgeoning scientific discipline. This comprehensive review explores the bioavailability of natural products in pharmaceutical applications, shedding light on their intrinsic challenges and innovative strategies for improvement. The assessment encompasses the limitations including poor aqueous solubility, low permeability, and instability, which collectively impede the effective absorption of natural products in the human body hinder the effective utilization of these compounds, and underscores the critical need for enhanced bioavailability to unlock their full therapeutic potential. Such challenges have spurred research into innovative approaches to overcome these limitations and optimize bioavailability. In response to these challenges, this review highlights cutting-edge strategies, including nanoparticle formulations, lipid-based delivery systems, and prodrug design, as effective means to enhance bioavailability. These approaches aim to improve solubility, stability, and overall absorption, thereby maximizing the therapeutic efficacy of natural products in pharmaceutical formulations. Moreover, the review emphasizes the importance of understanding the interplay between formulation techniques and the physicochemical properties of natural products. By integrating these innovative approaches, researchers can tailor solutions to specific compounds, providing a roadmap for overcoming bioavailability limitations and advancing the integration of natural products into mainstream pharmaceutical practice.
