Tracheal intubation is a common procedure during General Anesthesia. It consists in introducing a probe into the trachea. This simple act remains not without risks. Various incidents and complications have been described due to this procedure. Among these is granulomas. Different factors and mechanisms are responsible for these complications. The prolongation of the intubation especially in intensive care remains the main causative factor of the development of granulomas, on the other hand this complication remains infrequent in anesthesia. The main clinical signs are dyspnea or a change in voice. Surgery is often required. Through two clinical cases of granulomas developed after surgery, the authors discuss the mechanisms and requirements for anesthetic management of this type of complication.
Probing atomic-scale processes at the ferrihydrite-water interface with reactive molecular dynamics

Published: March 2024

Interfacial processes involving metal (oxyhydr)oxide phases often control the mobility and bioavailability of nutrient and contaminant elements in soils, sediments, and water. Consequently, these processes influence ecosystem health and functioning and have shaped the biological and environmental co-evolution of Earth over geologic time. Here we employ reactive molecular dynamics simulations, supported by synchrotron X-ray spectroscopy, to derive accurate surface complexation model constants for ferrihydrite-water systems containing aqueous \ce{MoO_4^{2-}}. This is achieved by employing a force-field that is adept at capturing the realistic dynamics of surface restructuring, surface charge equilibration, and the evolution of the interfacial water hydrogen bond network in response to adsorption processes or proton transfer events. We inform surface complexation models by exploring the free energy landscape of \ce{MoO_4^{2-}} adsorption at the ferrihydrite-water interface at different concentrations. We find how hydration and adsorption induce changes in surface charge, prompting the surface to restructure into more disordered ferrihydrite phases. We observe how the dynamics of adsorbed complexes are concentration-dependent and how surface restructuration, along with adsorption, influence the interfacial hydrogen bond network. By incorporating reactivity, reactive molecular dynamics opens new avenues to study mineral-water interfaces, enriching and refining surface complexation models beyond their foundational assumptions.
Photoassisted amplification of chain-growth in CO2 hydrogenation: Switching selectivities of heterogeneously catalyzed reactions with light
Authors: Becker Henning , Ziegenbalg Dirk , Güttel Robert
Published: March 2024

Selective carbon-carbon bond formation is a major challenge for chemical transformations to meet the global sustainability targets, which requires game-changing concepts instead of further improvement of conventional catalyst materials. In this work, a new paradigm to tune the selectivity of thermal catalytic systems is presented by using light as an external trigger to switch the selectivity from pure reduction to carbon-carbon bond formation. In a ruthenium-catalyzed CO2 hydrogenation reaction, chain-growth is initiated through irradiation with light, eventually leading to the formation of higher hydrocarbons instead of solely methane. Photoassisted reaction control was differentiated from photokinetic and photothermal effects by sophisticated thermal imaging and kinetic modelling. A light-induced change of the sorption properties of the solid catalyst surface was identified as reason for the changes in selectivity. The results render the exploitation of photoassisted effects as highly potent general strategy for comprehensive reaction control of reactions catalyzed by solids.

Authors: Kawamoto Takuji , Hisayuki Mai , Kamimura Akio
Published: March 2024

The rate constants for the radical addition of a trifluoromethyl radical to aryl-substituted vinyl triflates have been determined by applying competition kinetics at a single concentration point. The rate constants range from 4.1 × 106 to 5.6 × 106 M−1 s−1 and depend on the electronic properties of the benzene rings on the aryl-substituted vinyl triflates.
Water and q-Gaussians (Raman Spectroscopy)
Authors: Sparavigna Amelia Carolina
Published: March 2024

A large literature exists about the Raman spectroscopy of water. Here we present some articles regarding the spectral region between 2800 and 3800 cm−1, that is the O-H stretching Raman band, and the proposed decomposition obtained by means of Gaussian profiles. We will also consider the decomposition of this region with three q-Gaussian functions, instead of the five Gaussians usually considered. Being the q-parameter of q-Gaussians related to the correlation time of stochastic Kubo approach to fluctuations, we propose its use to characterize the local environment of O-H bonds.

Published: March 2024

DNA-encoded library (DEL) technology has proven to be a powerful method for discovering novel inhibitors for diverse targets. Particularly when combined with machine learning (ML), the DEL-ML workflow expands the chemical space and enhances cost-effectiveness, offering new opportunities to find desired hit molecules. Heme oxygenase-1 (HO-1), primarily a heme-degrading enzyme, has been identified as a potential therapeutic target in diseases such as cancer and neurodegenerative disorders. Despite years of study, the HO-1 inhibitor toolbox remains limited. Here, we report the discovery of five series of novel scaffold HO-1 inhibitors using a DEL-ML workflow that emphasizes the model’s uncertainty quantification and its domain of applicability. The DEL-ML model demonstrated a strong ability to extrapolate to novel chemical spaces by identifying new structures. Approximately 33% of the predicted molecules, validated by biophysical assays, had a binding affinity of K¬D < 15 µM, with the strongest affinity being 141 nM. Fourteen tested molecules showed over 100-fold selectivity towards HO-1 over Heme oxygenase-2 (HO-2). These molecules are also structurally novel compared to the reported HO-1 inhibitors. Further, binding mode simulations via docking provided insights into the possible selectivity rationale of some selective series.

Published: March 2024

Aromatic and antiaromatic ring currents can reveal global electronic delocalization around the circumference of pi-conjugated macrocycles, although these phenomena are poorly understood in large rings. Here we present the template-directed synthesis of a fully pi-conjugated cyclic porphyrin 12-mer consisting of six b,meso,b-edge-fused porphyrin dimers connected by six butadiyne bridges. The lowest energy pi-pi* absorption band of this partially fused nanoring is shifted far into the NIR, confirming the strong pi-conjugation around the circumference of the macrocycle. Investigation of the oxidized and reduced nanoring-template complex by 1H and 19F NMR spectroscopy demonstrates the presence of coherent global (anti)aromatic ring currents, consistent with DFT calculations. The stronger -conjugation enables global charge delocalization even at low levels of oxidation or reduction. These findings open new avenues for the engineering of cyclic molecular wires.
The role of fine particles in the stability of emulsion in the naphthenic froth treatment (NFT) process
Authors: Velayati Arian , Zeng Hongbo
Published: March 2024

This study investigates the role of fine particles in stabilizing emulsion in the naphthenic froth treatment (NFT) process. The characterization results of different types of solids collected from the diluted bitumen froth indicate that kaolinite is the dominant clay mineral in the composition of NFT solids. There were differences in the mineralogy of the fine samples depending on the phase (carrier fluid) from which the samples were collected. FTIR analysis shows that the fines that remain in the diluted bitumen even after several hours of sample retention time are mainly kaolinite, though the presence of other minerals such as siderite is very likely. Moreover, the presence of organic functional groups on the surface of the particles is confirmed for all types of solids in the FTIR analysis, regardless of the washing and drying procedures employed. Inspection of the different layers of the diluted bitumen via micrography and measurement of the solids concentration shows higher fine content and smaller particles in the top layer, a dire situation for destabilizing the emulsion in the top layer, supported by the observation that the water droplets in this layer are tiny. Solid partitioning tests revealed the solid particles migrate to the interfacial region and the aqueous phase. The concentration of particles increased in the interfacial region with the presence of asphaltene in the oil phase (dominant effect) and the increased polarity of the oil. The wettability measurements show that without the coverage of solid particles with organics (asphaltene-resin molecules), the fine particles are extremely hydrophilic. The adsorption of asphaltene-resin matter on the fine particles increased the hydrophobicity of the fines, a situation that promotes the partitioning of the fine particles at the interfacial region and the stability of the droplets. It was observed that the contact angle increased with the decreasing polarity of the oil phase. In the interfacial tension measurements, the fine solids with minimal asphaltic matter coverage did not remain suspended in the oil phase and either sedimented rapidly or migrated to the air-oil interface, unlike the organics-covered solids which remained immersed in oil. No decrease in the interfacial tension was recorded for the water-oil systems in the presence of fine solids. Interfacial rheology measurements illustrate the viscoelastic behavior of the interfacial film at lower frequencies and higher fine particle concentrations. We conclude that if not for the interaction between the asphaltic matter and the fine particles, the emulsion stability by fine particles would have been very unlikely.

Published: March 2024

KRAS is a proto-oncogene encoding a small GTPase. Mutations contribute to ∼30% of human solid tumours, including lung adenocarcinoma, pancreatic, and colorectal carcinomas. Most KRAS activating mutations interfere with GTP hydrolysis, essential for its role as a molecular switch, leading to alterations in their molecular environment and oncogenic signalling. However, the precise signalling cascades these mutations affect are poorly understood. Here, APEX2 proximity labelling was used to profile the molecular environment of WT, G12D, G13D, and Q61H-activating KRAS mutants under starvation and stimulation conditions. Through quantitative proteomics, we demonstrate the presence of known KRAS interactors, including ARAF and LZTR1, which are differentially captured by WT and KRAS mutants. Notably, the KRAS mutations G12D, G13D, and Q61H abrogate their association with LZTR1, thereby affecting turnover. Elucidating the implications of LZTR1-mediated regulation of KRAS protein levels in cancer may offer insights into therapeutic strategies targeting KRAS-driven malignancies.

Published: March 2024

Histamine is the most common cause of human foodborne illness and is found to be associated with the consumption of fish products especially in scombroid fishes containing unusual levels of histamine. In this study, histamine-producing bacteria in the Frigate Tuna, Auxis thazard samples of the local Ukkadam fish market of Coimbatore were investigated. Among 12 isolates 4 were found to be prominent histamine producing bacteria. An automated microbiology system called VITEK, a biochemical test analyzer was used for the identification of bacteria, and four isolates were tentatively identified as Sphingomonas paucimobilis; Proteus vulgaris; Providencia rustigianii, and Neisseria zoodegmatis. The isolation of histamine-producing bacteria from the muscle emphasizes the possible importance of muscle as a reservoir for bacterial contamination. The study suggests that the practice of more hygienic and sanitary conditions during the handling and processing of fish is required to minimize the contamination of such histamine-producing bacteria.
How were professional boundaries developed and navigated in my practice as a student music therapist?
Authors:   , Bellringer Deborah
Published: March 2024

This exegesis explores how professional boundaries were developed and navigated in my practice as a student music therapist. Boundaries are an important aspect of therapy. The motivation for this research topic came from my interest in developing my ability to remain professional in the intimate therapeutic relationship and to ensure that I could navigate transference and countertransference. I used an interpretivist inquiry, with a hermeneutic lens, which examined the data from the context of my lived experiences during practicum. The data were from secondary sources, which included clinical notes, my reflexive journal and supervision notes. The two facilities I attended for practicum were a school for students with disabilities and a day centre for adults with disabilities. A thematic analysis of the data revealed that I did not struggle with maintaining boundaries in the ways I initially thought I would, however other boundaries that I navigated emerged and are discussed. Some of these boundaries were pre-conceived, while other boundaries I found I had to extend. Four key themes were developed using thematic analysis: The boundaries around navigating my position as a student; pushing my knowledge boundaries around people’s way of being; extending boundaries of music making in my music therapy practice to include non-normative, inclusive ways of playing; and, how music was a boundary that supported the creation and deepening of trust and connection.
The Prognostic Value of Red Cell Distribution Width in Critically Ill Cerebral Infarction Patients: A Retrospective Cohort Study
Authors: Zhao Lingyan , Wu Linna , Li Gui-Ping
Published: March 2024

Objective: Red blood cell distribution width (RDW) has been utilized as a prognostic indicator for mortality risk assessment in cardiovascular and cerebrovascular patients. Nevertheless, the prognostic significance of RDW in critically ill patients with cerebral infarction is yet to be investigated. The objective of this study is to examine the association between RDW and the risk of all-cause mortality in cerebral infarction patients admitted to the intensive care unit (ICU). Method: A retrospective cohort study was conducted using the Medical Information Mart for Intensive Care IV 2.2 (MIMIC-IV) intensive care dataset for data analysis. The main results were the all-cause mortality rates at 3 and 12 months of follow-up. Cumulative curves were plotted using the Kaplan-Meier method, and Cox proportional hazards analysis was used to examine the relationship between RDW and mortality rates in critically ill cerebral infarction patients. Results: The findings indicate that RDW serves as a significant prognostic factor for mortality risk in critically ill stroke patients, specifically at the 3 and 12-month follow-up periods. The observed correlation between increasing RDW levels and higher mortality rates among cerebral infarction patients further supports the potential utility of RDW as a predictive indicator. Conclusion: RDW emerges as an independent predictor of mortality risk during the 3 and 12-month follow-up periods for critically ill patients with cerebral infarction.

Authors: Shanmugam Kirubanandan , Chandrasekar Narendhar , Balaji Ramachandran
Published: March 2024

Fibrous substrates made of cellulose like paper and paperboard are widely used in packaging. Furthermore, cellulose materials are biodegradable and completely safe for the environment. The water vapor barrier properties of paper and paperboard are limited due to the hydrophilic nature of cellulose fibrils. Paper is frequently combined with other materials, such as plastics, wax, and aluminum to improve its water barrier properties. Unfortunately, these materials lead to significant environmental problems and are difficult to recycle. Nanocellulose has shown the potential of being a substitute natural nanomaterial for creating environmentally friendly and sustainable barrier materials for a range of uses, including food packaging materials and substrates for the development of functional materials. Numerous cellulose sources can be used to create nanocellulose, which offers benefits like a high aspect ratio and tensile strength, making it useful for a variety of applications. The production of nanocellulose is done through a variety of processes. Potential biomedical applications of nanocellulose are tissue engineering, drug delivery, wound dressings, biosensors, implants and prosthetics, and nerve regeneration. Its application in these fields will result in the advancement of medical technology and the improvement of healthcare outcomes. Furthermore, biodegradable materials, barrier coatings, antimicrobial packaging, sustainable packaging solutions, smart packaging, and lightweight, high-strength packaging can all be made with nanocellulose. Nanocellulose-based packaging will improve the sustainability and efficiency of the packaging supply chain while providing environmentally friendly substitutes for conventional packaging materials.

Сільськогосподарська освіта на Поділлі на початку 20 ст. (на прикладі школи у с. Гуменному)
Authors: Тригуб Олександр , Степанчук Юрій
Published: March 2024

Розвиток аграрної освіти на українських землях імперської доби продовжує залишатися маловивченим, а в деяких губерніях взагалі є білою плямою, або має значні лакуни у своєму висвітленні. Отже, метою статті є реконструкція становлення та розвитку Гуменської практичної школи садівництва і сільського господарства (1902-20), аналіз її діяльності та результатів.

Історичний розвиток зазначеного навчального закладу свідчить, що ключову роль у розвитку навчальних закладів аграрного профілю відігравали органи місцевого самоврядування та приватна ініціатива. Саме завдяки їх енергії на початку 20 ст. постала зазначена школа. При цьому цю школу дійсно можна іменувати «селянською», адже 88% учнів складали селяни Подільської губернії та сусідніх губерній. Безкоштовне навчання, наявність стипендіальних програм від земства та приватних осіб приваблювали до навчання навіть найбіднішу селянську молодь. Окрім цього, у діяльності школи були зацікавлені місцеві великі землевласники, які оплачували навчання учнів у школі, переслідуючи власні інтереси. З іншого боку – вимога навчання аграрній науці, велика частка у навчанні практичної складової, праця по господарству без вихідних приводила до того, що лише ⅖ завершувала навчання.

Училище мало достатньо потужний викладацький колектив, де усі штатні педагоги мали професійну фахову освіту. Натомість спостерігаємо досить значну плинність кадрів серед вчителів як професійних, так і загальноосвітніх чи спеціальних предметів.

Натомість, не дивлячись на усі недоліки, які мав означений навчальний заклад, він поклав початок формуванню системи аграрної освіти українського селянства на Поділлі, яка трансформувалася у сучасну систему підготовки фахівців аграрної галузі, що є стратегічно важливою для української державності та її економіки.

Фінансування. Стаття підготовлена за результатами фундаментального дослідження «Соціокультурний простір України другої половини ХІХ – першої третини ХХ ст.: селянський світ» (номер державної реєстрації: 0123U101600) за підтримки Міністерства освіти і науки України.
Спільна політика у сфері безпеки та оборони Європейського Союзу в постбіполярну добу: стан розвитку та можливості для України
Authors: Стецюк Микола
Published: March 2024

У статті розкривається процес розвитку спільної політики Європейського Союзу (ЄС) у сфері безпеки й оборони після завершення Холодної війни. Здійснено огляд ключових нормативно-правових актів ЄС, які встановлюють засадничі принципи Спільної політики у сфері безпеки та оборони (СПБО), як складової частини Спільної зовнішньої та безпекової політика (СЗБП) Європейського Союзу. Охарактеризовано сучасний стан розвитку СПБО, зокрема акцентовано увагу на форматах «Постійної структурованої співпраці (PESCO), та наголошено на можливостях щодо приєднання України до даного формату перед офіційним вступом до ЄС.

Усього за рік після розпаду Радянського Союзу процес європейської інтеграції досягнув видатної віхи: Маастрихтським договором від 1992 р. було засновано Європейський Союз (ЄС). Ним же було впроваджено Спільну зовнішню та безпекову політику як один зі стовпів ЄС. Рівно через двадцять п’ять років – у 2007 р. – було підписано Лісабонський договір, який вивів СПБО ЄС на якісно новий рівень. По-перше, Договір про ЄС у редакції Лісабонського договору містить зобов’язання про взаємодопомогу в разі збройної агресії проти однієї з держав-членів. По-друге, проголошується амбітне бачення, згідно з яким СПБО має стати основою для перспективного переходу ЄС до «колективної оборони», – щоправда, за умови наявності консенсусу серед усіх держав-членів. По-третє, Лісабонським договором передбачено формат «Постійної структурованої співпраці» (PESCO), у рамках якого держави-члени можуть вступати в тіснішу співпрацю між собою, при цьому беручи на себе певні розширені зобов’язання. Останній формат, попри орієнтованість на вузькоспеціалізовані проєкти та неоднорідну залученість держав-членів, може стати першим майданчиком для раннього залучення України до СПБО.

Published: March 2024

Graphite is a carbon-based material potentially utilized in numerous applications, such as electrodes for supercapacitors, lithium-ion batteries, and absorbers for water treatment. Biomass graphite is a beneficial candidate for low-cost yet valuable graphite. In this work, coconut shells, the abundant materials with high carbon contents, were successfully transformed into valuable coconut shell graphite (CSG) using metal catalytic graphitization with nickel as a catalyst at low-temperature conditions of ~1200 °C. Nickel concentration varied between 2 mmol, 3 mmol, and 5 mmol per gram of carbon. The samples were further examined using X-ray diffraction (XRD), Raman Spectroscopy, and Transmission Electron Microscope (TEM). The high graphitization degree of ~ 72 % was confirmed by X-ray diffraction analysis. That was further supported by the high-ordered stacking carbon layer that appeared in HR-TEM images. Meanwhile, Raman spectroscopy confirms that nickel impregnation diminished the structural defect of samples and increased the sp2-carbon bond indicated by its rise of IG/ID. The IG/ID values of CGS and CGS-Ni5mmol are 0.86 and 0.92, respectively.
