Authors: Katiyar Shikha , Rao Devendra Pratap , Verma Narendra Kumar , Gautam Amit Kumar , Verma Ashish , Singh Chandra Prakash , Shankar Vijay , Gautam Yashveer
Published: February 2024

Using di-2-furanylethanedione and 5-bromo-3-methylbenzene-1,2-diamine we prepared a monomeric [MoO2(SL)] with a Schiff base, as well as 4 different compounds using the formulation [MoO2(MSL). We investigate how [MoO2(SL)] reacts with 1,3-diketones. Several characterizations are discussed in this article, including molar conductance measurement, elemental analysis, UV-Vis, IR, NMR, and thermal measurements. Molybdenum has a six-coordination number. All five MoO2(VI) compounds have distorted octahedral arrangements. Molybdenum octahedra have four N-atoms and two oxidized O-atoms. Against S. aureus and S. typhi, all synthesized compounds showed moderate activity. The chelation hypothesis is used to define the progression of the antibacterial task.

Published: February 2024

In the present study, we have reported the synthesis of a novel thiophene - based dipodal chelator ligand MPT (N1, N3-bis(3-((E)-thiophen-2-yl)methylene)amino)propyl)malonamide). Further, the physio-chemical properties of as-synthesized ligand was analyzed employing state-of-the-art characterization tools such as 1H NMR, 13C NMR, and IR spectroscopy. In order to calculate the protonation constant for the ligand MPT and formation constants for the ligand MPT with Fe2+ metal ion potentiometric and spectrophotometric analysis were carried out. Further, to analyze the coordination behavior of the ligand MPT with Fe2+ metal ion at room temperature in a highly aqueous medium spectrophotometric analysis was carried out. On the other hand, the theoretical studies for the ligand MPT and its complex with Fe2+ ion were performed employing a semi-empirical method and density functional theory. Further, the structure optimization of the ligand MPT was obtained using the PM6 parameter and B3LYP/6-311(d,p) level for ligand and DGDZVP for metal complex calculations respectively.
Preparation and Characterization of AB2-Type Miktoarm Star-Shaped Nanomaterials Having Lactic Acid as an Arm
Authors: Panchal Siddhi S , Vasava Dilip V
Published: February 2024

A series of seven AB2-type hydrophobic miktoarm star polymeric nanomaterials were nanofabricated using coupling-onto approach. These tridentate nano-stars were synthesized using carbodiimide chemistry and characterized using FT-IR, 1H NMR and DLS techniques. Lactic acid is chosen as “arm A” and amino adipic acid as “core”, while seven biodegradable synthetic amides and polyamides as “arm B” were used individually. The diameter of the smallest nano-star LCE was 558.6 nm and largest nano-star LTD was 733.3 nm. The presence of long aliphatic chain in the LDE and LDD as well as presence of aromatic ring in LTE and LTD give them a bigger diameter in comparison to LCE, LLE and LLD. TGA analysis of the product reported a significant loss of 35% by total mass at 400ᵒC, indicating thermal degradation. The products proved to be biodegradable after 15 days of biological treatment. Biodegradation was structurally confirmed by FT-IR analysis of degraded samples.
Feminism and Capitalism under the Nuclear Cloud & Barbie
Authors: Maines Rachel
Published: February 2024

abstract: The Warner Brothers/Mattel movie Barbie is meant to be about feminism and capitalism in complicated, comical, and nuanced ways. It mostly succeeds in its dual purpose of comedy and inspiration. The doll's origin in 1959 places her and her consort, Ken, squarely in the context of the Cold War, although neither the movie nor the doll's long and successful marketing history acknowledges anything outside the sunny world of Barbie Land. The nuclear shadow does affect the movie's reception, however, in the form of international protests over the dashed lines scrawled on a supposed "World Map" in one scene. For nations in and around the South China Sea, the dashed lines evoke the specter of war in a nuclear age over claims to territorial sovereignty. Yet director Greta Gerwig's film is a runaway success, the first film solo directed by a woman to gross more than a billion dollars and counting.

Fourier analysis in single photon imaging
Authors: Laurenzis Martin , Bacher Emmanuel
Published: February 2024

Single photon imaging has become an established sensing approach. Compared to intensity imaging, versatile advantages has been demonstrated such as imaging with high sensitivity, at high frame rate and with high dynamic range. In this paper, we investigate the Fourier analysis of single photon counting at a frame rate of approximately 100 kHz and high spatial resolution of 512 px × 512 px. We observed signal modulation in raw data as well as in data converted to photon flux, but with the data processing the signal’s frequency response is affected by significant damping. Thus, analysis sensible to signal frequency should work on the raw single photon counting signal. Furthermore, imaging of magnitude and phase in the Fourier domain can visualize areas of certain signal modulation and the gradient of the phase angle can reveal the direction of movements. Finally, we have applied our method to real world scenarios by analyzing unmanned aerial vehicle’s motion in outdoor experiments.
DeepD3, an open framework for automated quantification of dendritic spines
Authors: Fernholz Martin H. P. , Guggiana Nilo Drago A. , Bonhoeffer Tobias , Kist Andreas M.
Published: February 2024

Dendritic spines are the seat of most excitatory synapses in the brain, and a cellular structure considered central to learning, memory, and activity-dependent plasticity. The quantification of dendritic spines from light microscopy data is usually performed by humans in a painstaking and error-prone process. We found that human-to-human variability is substantial (inter-rater reliability 82.2±6.4%), raising concerns about the reproducibility of experiments and the validity of using human-annotated ‘ground truth’ as an evaluation method for computational approaches of spine identification. To address this, we present DeepD3, an open deep learning-based framework to robustly quantify dendritic spines in microscopy data in a fully automated fashion. DeepD3’s neural networks have been trained on data from different sources and experimental conditions, annotated and segmented by multiple experts and they offer precise quantification of dendrites and dendritic spines. Importantly, these networks were validated in a number of datasets on varying acquisition modalities, species, anatomical locations and fluorescent indicators. The entire DeepD3 open framework, including the fully segmented training data, a benchmark that multiple experts have annotated, and the DeepD3 model zoo is fully available, addressing the lack of openly available datasets of dendritic spines while offering a ready-to-use, flexible, transparent, and reproducible spine quantification method.

Authors: Madrazo Lorenzo , Choo-Foo Jade , Domecq Marie-Cécile , LaDonna Kori A. , Humphrey-Murto Susan
Published: February 2024

Background

Illness presenteeism (IP) is the phenomenon where individuals continue to work despite illness. While it has been a prevalent and longstanding issue in medicine, the recent onset of the COVID-19 pandemic and the growing movement to improve physician wellness brings renewed interest in this topic. However, there have been no comprehensive reviews on the state of literature of this topic.

Purpose

The main aim of this scoping review is to explore what is known about presenteeism in physicians, residents, and medical students in order to map and summarize the literature, identify research gaps and inform future research. More specifically: How has illness presenteeism been defined, problematized or perceived? What methods and approaches have been used to study the phenomenon? Has the literature changed since the pandemic?

Method

Using the Arksey and O’Malley framework several databases will be searched by an experienced librarian. Through an iterative process, inclusion and exclusion criteria will be developed and a data extraction form refined. Data will be analyzed using quantitative and qualitative content analyses.

Potential implications of results

By summarizing the literature on IP, this study will provide a better understanding of the IP phenomena to inform future research and potentially have implications for physician wellness and public health.
Protective effects of ectoine on articular chondrocytes and cartilage in rats for treating osteoarthritis
Authors: Li Peng , Huang Yong , Miao Lishuai , Zhu Zhiqi , Shi Zhanjun
Published: February 2024

Osteoarthritis (OA) is a chronic degenerative disease that primarily includes articular cartilage destruction and inflammatory reactions, and effective treatments for this disease are still lacking. The present study aimed to explore the protective effects of ectoine, a compatible solute found in nature, on chondrocytes in rats and its possible application in OA treatment. In the in vitro studies, the morphology of the chondrocytes after trypsin digestion for 2 min and the viability of the chondrocytes at 50°C were observed after ectoine treatment. The reactive oxygen species (ROS) levels in chondrocytes pretreated with ectoine and post-stimulated with H2O2 were detected using an ROS assay. Chondrocytes were pretreated with ectoine before IL-1β stimulation. RT‒qPCR was used to measure the mRNA levels of cyclooxygenase-2 (COX-2), metallomatrix proteinase-3, -9 (MMP-3, -9), and collagen type II alpha 1 (Col2A1). In addition, immunofluorescence was used to assess the expression of type II collagen. The in vivo effect of ectoine was evaluated in a rat OA model induced by the modified Hulth method. The findings revealed that ectoine significantly increased the trypsin tolerance of chondrocytes, maintained the viability of the chondrocytes at 50°C, and improved their resistance to oxidation. Compared with IL-1β treatment alone, ectoine pretreatment significantly reduced COX-2, MMP-3, and MMP-9 expression and maintained type II collagen synthesis in chondrocytes. In vivo, the cartilage of ectoine-treated rats exhibited less degeneration and lower Osteoarthritis Research Society International (OARSI) scores. The results of this study suggest that ectoine exerts protective effects on chondrocytes and cartilage and can, therefore, be used as a potential therapeutic agent in the treatment of OA.
Effect of R&D activity on level of innovation of EU countries in 2014 and 2020
Authors: Piotrowska Katarzyna , Szymura Aleksandra , Wanicki Piotr
Published: February 2024

Research and development carried out by companies are pivotal for innovative economies of countries, especially in the unpredictable and changing social, economic and political environment. In this context, it is very important to answer, which factors identify the effectiveness of measures in relation to R&D activity and innovativeness in EU countries and how should the degree of development of a country be assessed in terms of R&D activity? The purpose of this article is to verify level of innovativeness and degree of research and development (R&D) activity in EU countries in the years 2014 and 2020 using Hellwig’s measure of development. To achieve this, qualitative and quantitative analysis, synthesis, deduction and induction, comparative analysis, and reasoning by analogy of phenomena were employed. The research was conducted on the basis of the expertly selected variables for their relation to R&D activity from a number of sources, such as Eurostat, World Bank Data, etc.. The indicated variables were analysed using statistical methods and then subjected to a linear ordering procedure based on the Hellwig development pattern method. Thanks to the research results, it is possible to indicate areas in which the initiation of activities would have the greatest degree of influence on development of R&D activity, thus influencing the increase in the level of innovativeness of a country. Indicators relating to R&D activity were selected and then used as variables to study the effect of the degree of R&D activity in EU countries in the years 2014 and 2020 on the level of innovativeness of these countries. The conducted research coincides with the results presented in the European Innovation Scoreboard. There is a significant correlation between the development of R&D activities and innovation performance.
Uniform-undone: A study in the repurposing of military attire through history and in experimental practice
Authors: Crivellaro Tricia , Lungu Anthony
Published: February 2024

This article reports on a practice-led research project focusing on military attire as both a subject and an agent of change. An historical account situates the origins of modern military attire within the emergent modern state during the nineteenth century, and then examines its subsequent role as part of the project to create a ‘new man’ in Fascist Italy and Nazi Germany. This is followed by a critical discussion of the decoupling of military attire from its associations with the institutions of state and warfare during the Vietnam War – where fatigues entered the popular atmosphere as casual attire that was variously subversive, countercultural and aesthetic in nature. Employing the MA-1 bomber jacket and camouflage as illustrative examples, the article then highlights the continued repurposing of military attire and its concomitant commoditization. The practice-led research employs object-based research, speculative artistic methodologies and various garment-making techniques in the production of a novel ‘military’ garment that explores the symbolism of military uniforms and critiques their traditional concept as utilitarian combat wear. The material outcomes interrogate linkages between military attire and notions of masculinity, class and gender identity. The research project further attempts to speculate on how military attire may be repurposed within the atmosphere of the twenty-first century – one that contemplates new forms of identity and other challenges that are responsive to contemporary circumstances.
Unmasking the dictator: How digital technologies expose authoritarianism in Belarus and Zimbabwe
Authors: Mututwa Wishes Tendayi , Akpojivi Ufuoma
Published: February 2024

Authoritarian governments seem to use the same methods of coercion the world over. Recent developments in Belarus and Zimbabwe resonate with this observation. President Alexander Lukashenko prevailed in a deeply flawed and controversial election which his opponents claimed was rigged in July 2020, triggering massive countrywide protests by the opposition supporters. In Zimbabwe, corruption over COVID-19 procurement, coupled with a dire economic situation, pushed citizens to organize demonstrations. Both Belarus and Zimbabwean security personnel employed a heavy-headed approach to thwart demonstrations, committing gross human rights abuses under the cover of darkness or under face masks. Although digital activism has received so much credit as a formidable force to challenge power, its success in dismantling oppressive regimes and systems is a subject of debate. In light of this debate, this qualitative article employed counterpublics as a theoretical lens to explore Twitter and digital tools that allow ordinary citizens and activists to counter human rights abuses in authoritarian environments, making future quests for justice possible.

Published: February 2024

Introducción: Debido a la pandemia por el SARS-CoV-2 se produjeron importantes restricciones para la atención presencial y de aforo en los centros sanitarios, lo cual ha desembocado en la merma en algunos aspectos de la calidad de la atención sanitaria y de la satisfacción de los usuarios. El objetivo de este trabajo es valorar el grado de satisfacción de las madres respecto a la asistencia del seguimiento de su embarazo durante la pandemia.
Pacientes y métodos: 1 321 madres que dieron a luz entre marzo de 2019 y mayo de 2021. Estudio descriptivo retrospectivo, basado en encuestas en forma de formularios online.
Resultados: El 42 % de las madres consideran satisfactoria la atención a su embarazo frente al 58 % que la considera insatisfactoria. Si comparamos con los embarazos atendidos antes del inicio del primer confinamiento, el grado de satisfacción se reduce de forma significativa a partir del 14 de marzo del 2020, de un 75 % a un 41 % (p < 0,001). Las causas de insatisfacción que verbalizan con más frecuencia han sido la escasa preparación para el parto y la lactancia, la reducción de las visitas presenciales a los centros y la frecuente ausencia forzada de acompañante en las consultas y exploraciones.
Conclusiones: Las restricciones impuestas por la pandemia han afectado de forma significativa a la satisfacción de las mujeres embarazadas respecto al seguimiento de su embarazo y la preparación para el parto y la lactancia.

Authors: Gonçalo de Araújo Elana , Maria Marta dos Santos Silva Nóbrega
Published: February 2024

As literaturas africanas de língua portuguesa, comparadas com as de outros países, são consideradas recentes.  Situadas, panoramicamente, em uma divisão colonial e pós-colonial, essas literaturas ainda são pouco exploradas nas escolas brasileiras, ainda que seu ensino tenha se tornado obrigatório em conformidade com o que preceitua a Lei 10.639/03. Um dos ganhos da leitura e do estudo dessas literaturas constitui-se em possibilidades de trocas interculturais, decoloniais e antirracistas que apresentam implicações psicológicas, sociais, culturais e políticas bastante significativas para o meio educacional do ensino básico. E neste sentido que o presente artigo descreve e analisa o modo como as literaturas africanas de língua portuguesa são abordadas no material produzido pelo Poliedro – Sistema de Ensino, tendo como referência as orientações contidas na Base Nacional Comum Curricular.

Authors: Rieuwpassa Jessica Athalia , Sugito Sugito , Widiharih Tatik
Published: February 2024

The COVID-19 pandemic has led to restrictions on activities in public places or facilities, such as cinemas. This has resulted in increased users of streaming service applications such as Netflix where users can access videos or movies online. Netflix users continue to increase from year to year, but its users began to decrease along with other streaming applications. Related to this, sentiment analysis was carried out on the classification of positive and negative reviews given by users on the Google Play website. The classification is expected to produce good accuracy and be analyzed so that it can be useful information for Netflix and potential users of streaming applications. The Naive Bayes Classifier method is a classification algorithm that is easy to apply and has high effectiveness for classifying text. This method utilizes the concept of conditional probability and has a strong assumption of independence. This study uses 2.850 Netflix application review data on Google Play which is then processed and divided into training data and test data with a ratio of 80:20. Classification with the Naive Bayes Classifier produces an accuracy value of 87,33%, a precision value of 87,6%, a recall value of 93,53%, and an F-measure value of 90,47% so it can be concluded that the performance of the Naive Bayes method is good for classifying user reviews of the Netflix.
Morphometric traits, carcass characteristics and biochemical composition of meat between local and synthetic Algerian rabbit genotypes
Authors: Sanah I. , Boudjellal A. , Becila S.
Published: February 2024

The aim of this research was to study the genetic and sex effects on morphometric traits, carcass characteristics and biochemical composition of rabbit meat of two Algerian breeds, local population and synthetic line (ITELV2006). For this purpose, 60 animals (30 per group) from 90 d of age were used. The body weight and the morphometric traits recorded were determined using a digital weighing scale and flexible tape. At slaughter, carcass traits, and biochemical meat quality characteristics such us protein, fat, ash, moisture content and fatty acids composition were measured. The results obtained revealed that the synthetic line has higher values of morphometric measurements than the local breed. The sex factor and the interaction genotype X sex had a significant effect only on chest circumference (P < 0.05). It is also observed, that the majority of carcass characteristics were more affected by genetic than by genetics. Which body weight at slaughter of males and females derived from synthetic lines were 41% and 22% higher than local rabbits respectively. Furthermore, the new line displayed a good meat yield (60%) with a higher mean value (+ 5%) of dressing out % rather than the local one. Regarding, the proximate biochemical composition of meat, the synthetic line has shown also the highest content of protein and fat (P < 0.05). Concerning with fatty acids profile; the local breed exhibited the highest content of n3 and n6 polyunsaturated fatty acids (n3 and n6 PUFAs), consequently, the lower value of n-6: n-3 ratio (9.82) and the highest value of polyunsaturated fatty acids to saturated fatty acids (PUFAs/SFAs: 0.73). Finally, it should be emphasized that the relevant differences recorded in this experiment are assumed to be primarily genetic, thus, sex might be regarded as a minor factor. The synthetic showed better characteristics due to its genetic potential. Therefore, it is recommended to be used for Algerian meat production.

The aim of this paper is to answer the question: What impact did the coronavirus pandemic have on the digitalization and electronization of tax administration in the Czech Republic? An analytical approach is used to identify the changes adopted during the coronavirus pandemic that affected the digitalization and electronization of tax administration. These changes are then assessed in terms of their specific impacts on digitalization and computerisation and whether the pandemic was the reason for their adoption. The paper falsifies the hypothesis that the coronavirus pandemic had a positive effect on the digitalisation and electronization of tax administration and concludes that the coronavirus pandemic had essentially no effect on the tax administration measures taken leading to digitalization and electronization.
Výklad daňových zákonů v trestním a daňovém řízení
Authors: Lichnovský Ondřej
Published: February 2024

The article focuses on the interpretation of tax laws in the context of criminal and tax proceedings. It stems from the premise that although tax and criminal proceedings are independent, they overlap in practice in certain areas, leading to irreconcilable differences. The aim of the article is to analyze these common points, clarify the causes of discrepancies, and assess whether they are in accordance with the law. A total of 9 combinations of tax and criminal proceedings have been identified. For many of these combinations, it is highlighted that the difference in the outcome of the proceedings is related to the difference between the two proceedings. However, in one of the cases - the tax proceedings end without a finding and the criminal proceedings end with a conviction - the conclusion is drawn that it is most likely that there is misconduct by the tax administrator or the criminal authorities.

Dzieci „piszą” stan wojenny, dorośli „przepracowują” traumy. Pamięć stanu wojennego w świetle teorii Dominicka LaCapry
Authors: Berthold Kamila
Published: February 2024

Artykuł stanowi próbę zrozumienia traumy stanu wojennego. Przy pomocy aparatu pojęciowego wypracowanego przez Dominicka LaCaprę analizie poddane zostały dwa utwory współczesnej literatury polskiej – Wilczek K. Ryrych oraz Wroniec J. Dukaja. Chociaż myśl amerykańskiego badacza skupia się przede wszystkim wokół treści traumatycznych powiązanych z II wojną światową i Zagładą, to jednak jego teoria przystaje także do innych trudnych wydarzeń historycznych. Autorka artykułu stara się zrewidować sposób, w jaki pamięć o stanie wojennym została zoperacjonalizowana przez pisarkę i pisarza, a także spojrzeć na ich teksty poprzez pryzmat osobistej strategii oswajania traumy. Analizowane utwory pokazują, iż stan wojenny nie jest „doświadczeniem niczyim”, a więc właściwie obecnym-nieobecnym, dotykającym każdego i nikogo, przeciwnie – to ważny problem społeczeństwa polskiego, który wymaga jednak przenicowania oraz nowego, być może także kreatywnego spojrzenia.
Modeling the repetitions‐in‐reserve‐velocity relationship: a valid method for resistance training monitoring and prescription, and fatigue management

Published: February 2024

Establishing a relationship between repetitions left in reserve and the mean absolute velocity (RIR‐velocity relationship) during resistance training (RT) could allow for objective monitoring, prescription, and real‐time adjustment of the training load and set‐volume. Therefore, we examined the goodness of fit and prediction accuracy of general and individual RIR‐velocity relationships in the free‐weight back squat exercise. The effects of sex, training status and history, as well as personality traits, on the goodness of fit and the accuracy of these relationships were also investigated. Forty‐six resistance‐trained people (15 females and 31 males) performed a one‐repetition maximum (1RM) test, and two repetitions to failure (RTF) tests 72 h apart. We found greater goodness of fit of individual RIR‐velocity relationships compared to general RIR‐velocity relationships. Individual, but not general RIR‐velocity relationships established in the first testing session yielded acceptable prediction accuracy of RIR (mean error <2 repetitions) in the subsequent testing session, regardless of the load used. Similar results were obtained when both general and individual RIR‐velocity relationships were averaged across the loads, suggesting that a single RIR‐velocity relationship covering a range of loads can be used instead of traditional RT methods, potentially allowing for better fatigue management and more efficient adaptation.

Published: February 2024

Um zukünftige Produktionssysteme und -prozesse auf Flexibilität, Interoperabilität und Anpassungsfähigkeit auszurichten, sind Konzepte zur Realisierung durchgängiger, horizontaler und vertikaler Integration von Assets (physischen Betriebsmittel) notwendig. In der vorliegenden Arbeit werden ein konventioneller und ein fähigkeitsbasierter Ansatz zur Kommunikation und Steuerung in Produktionsumgebungen mittels Open Platform Communications Unified Architecture (OPC UA) untersucht. Der Schwerpunkt liegt auf der intelligenten Orchestrierung von fähigkeitsbasierten Steuerungslogiken, die in Kombination mit Agentensystemen eine erhöhte Flexibilität und Anpassungsfähigkeit bieten. Dieser Ansatz ermöglicht es, auf Produktionsfähigkeiten rekonfigurierbar zuzugreifen und sie zu effizienten Produktionsservices zu aggregieren. Die Arbeit beleuchtet die Potenziale und Herausforderungen beider Ansätze und zeigt, wie fähigkeitsbasierte Systeme zur Evolution von Produktionssystemen im Sinne der Industrie 4.0 beitragen können. Durch die Verwendung von OPC UA und die Integration von Multi-Agenten-Systemen mit Digitalen Zwillingen stellt das eingeführte Konzept des Skill Orchestration Agenten (SkillOA) einen fortgeschrittenen Ansatz dar, der nicht nur die Effizienz und Leistungsfähigkeit von Produktionsprozessen steigert, sondern auch eine adaptive und dynamische Rekonfiguration von Produktionssystemen ermöglicht, ohne den Quellcode von Maschinensteuerungen anpassen zu müssen. Die Diskussion umfasst die Bewertung der Leistung und Effizienz von fähigkeitsbasierten Architekturen, die Wirksamkeit des Einsatzes von OPC UA zur Unterstützung dieser Architekturen und die notwendigen Anpassungen im Konzept eines Ressourcenagenten für eine effektive Selbst-Rekonfiguration.
Does Uncertainty Matter for the Fiscal Consolidation and Investment Nexus?
Authors: Bournakis Ioannis , Ramírez-Rondán Nelson R.
Published: February 2024

The aim of this research paper is to investigate whether there are non-linearities in the relationship between fiscal consolidation and investment. To achieve this, we take into account the overall state of the economy, as represented by the level of uncertainty. We analyzed a sample of 27 OECD countries from 1996 to 2019 and identified two different regimes of low and high uncertainty. We found that the relationship between fiscal policy and investment is significantly different in these two regimes. In the low uncertainty regime, fiscal tightening has no significant effect on investment. In contrast, in the high uncertainty regime, fiscal tightening has a negative impact on investment, which is three times larger than in the low uncertainty regime. Our results are robust, and have been confirmed through a range of sensitivity tests.

Objectives

The clinical significance of bacteremia in patients with complicated pleural infection is still uncertain. We aimed to examine the incidence and clinical significance of bacteremia in patients with complicated pleural infection.

Methods

This retrospective study comprised of consecutive patients who received pleural drainage due to complicated parapneumonic effusion or empyema. The clinical, laboratory, and radiologic data and clinical outcome were compared between patients with and without bacteremia. Additionally, the factors associated with overall mortality were evaluated in these patients.

Results

Of 341 patients included in the analysis, 25 (7 %) had a positive blood culture. Blood culture testing added 2 % identification of causative pathogen compared to pleural fluid culture alone. By multivariable analysis, radiologic features of cavitary lesion, a RAPID score≥5, and a positive microbial culture in pleural fluid were independently associated with bacteremia. Despite these clinical distinctions, there was ultimately no significant difference in in-hospital mortality between patients with and without bacteremia (3 vs. 4 %, p=1.0). The only factor significantly associated with overall mortality among patients with complicated pleural infections was a higher RAPID score [HR=1.96 (95 % CI=1.35–2.84)].

Conclusions

The rate of bacteremia in patients with complicated pleural infection was 7 %. Blood culture testing demonstrated limited diagnostic yield and had minimal impact on clinical outcomes compared to pleural fluid culture. Therefore, it seems that blood culture testing is more advantageous for specific patients with suspected pleural infection who have cavitary lesions or a RAPID score≥5.
Exploring the crystal and molecular structures of methenolone and drostanolone enanthate
Authors: Turza Alexandru , Miclăuș Maria O. , Borodi Gheorghe
Published: February 2024

Methenolone and drostanolone are two popular synthetic anabolic-androgenic agents and dihydrotestosterone derivatives which belong to the steroid family. Two esterified prodrugs of methenolone and drostanolone, in the form of methenolone and drostanolone enanthate, have been described from a structural point of view. The crystal structure of drostanolone enanthate was determined by single crystal X-ray diffraction, while the crystal structure of methenolone enanthate was solved by the powder X-ray diffraction technique. The nature and magnitudes of intermolecular interactions were analysed quantitatively by means of crystal lattice energies and Hirshfeld surfaces.

A novel isocoumarin was isolated from the mycelia of the dark septate endophytic fungus Phialocephala fortinii. The chemical structure was determined to be 8-hydroxy-6-methoxy-3,7-dimethyl-1H-2-benzopyran-1-one based on mass spectrometry, 1H-nuclear magnetic resonance (NMR), and 13C-NMR spectroscopic analyses, including 2D-NMR experiments. The isolated compound inhibited root growth of Arabidopsis thaliana, suggesting its potential as a plant growth regulator.
ALİ TEOMAN’IN EDEBİYAT GÜNLÜKLERİ
Authors: YİĞİTLER Şener Şükrü
Published: February 2024

Avrupa’da bireyin öneminin vurgulanmaya başladığı Rönesans’a kadar uzanan günlük türü, Türk edebiyatına Tanzimat’ın ardından girer. Geç Osmanlı-erken Cumhuriyet dönemlerinde özellikle siyasilerin ve ordu mensubu isimlerin damgasını vurduğu bu tür, 1950’li yıllardan itibaren ünlü edebiyatçılarla anılmaya başlar. 1980 Kuşağı yazarlarından Ali Teoman yazarlık kariyerine koşut olarak tuttuğu günlüklerinde ağırlıklı olarak yazı denemelerine, edebiyat ve sanatın diğer dallarıyla ilgili görüşlerine, eleştirilerine, eserlerinin planlarına yer verir. Yazarın günlük olayların dökümünden ziyade birer ‘edebiyat günlüğü’ olarak tasarladığı bu kayıtlar, Ali Teoman’ın yazarlığı konusunda önemli bilgiler verdiği kadar onun hayatıyla kurmaca eserleri arasındaki bağı da ortaya koyar. Yazarın ölümünden önce yayınevine teslim ettiği yaklaşık yetmiş ciltlik külliyat bugüne kadar yalnızca Gezgin Günce (2011) ve Alacakaranlık Günce (2017) adlı iki kitap şeklinde okura ulaşır. On yedi yılı aşkın bir zamana yayılmasıyla Türk edebiyatı için de önemli bir belge değeri taşıyan bu günlük kayıtlar, Türk edebiyatının erken yaşta kaybettiği özgün bir isminin edebiyat dünyasını okurlara açan eldeki tek kaynaktır.
