The Outcome of Keystone Flap for Lower Extremity Defects: A Systematic Review
Authors: Marcevianto Kevin Varian , Wardhana Aditya , Putri Nandita Melati
Published: February 2025

Introduction : Lower extremity defect poses a significant challenge in reconstructive surgery due to the limited usability of soft tissue. The keystone flap which utilizes fasciocutaneous perforators, has emerged to be a potential technique in fixing soft tissue defects. However, scientific evidence, specifically on its effectivity and complication rate in lower extremity defect is lacking. Therefore, this systematic review aims to assess the outcome and potential complications correlated to the use of Keystone Flap in repairing lower extremity defect.
Method : This systematic review was done in accordance to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). Literature searching was conducted using four databases, which is PubMed Central, Embase, Scopus and Cochrane Library.
Result : A grand total of sixteen studies were included in the review. Among it, fourteen studies were case series. The others were cohort prospective and single arm interventional studies. Out of the 662 keystone flaps used, a total of 129 complications (19.5%,) were recorded, with the majority being infection or cellulitis (5%, n=33), delayed healing (4.5%, n=30), wound dehiscence (4.3%, n=28), and partial flap loss or necrosis (2%, n=13).
Conclusion: The keystone flap could be an alternative for lower extremity defect with a realtively low complication rate.
Psychological Landscape of Children With Cleft Palate: A Comprehensive Review
Authors: Christabella Rininta , Evillia Wati
Published: February 2025

Cleft lip and/or palate (CL/P) is a common congenital craniofacial abnormality with significant psychosocial implications. This review synthesizes recent research on the psychological landscape of children and adolescents with CL/P, emphasizing the impact on emotional well-being, social functioning, and quality of life. Psychological distress, including anxiety and lower self-esteem, is prevalent among individuals with CL/P, persisting into adulthood and influencing various aspects of mental health. While some studies suggest resilience or underreporting of psychological difficulties, others highlight enduring challenges in appearance satisfaction and emotional well-being. Factors such as familial support and satisfaction with appearance play crucial roles in positive adjustment. Social functioning and peer acceptance present significant challenges, with many children experiencing isolation and stigma. However, some demonstrate adaptive social behaviours, suggesting protective factors. Quality of life is adversely affected, emphasizing the need for holistic interventions addressing physical and psychosocial aspects. While treatments positively impact perceived quality of life, specific cleft types and comorbidities like obstructive sleep apnea further influence outcomes. Overall, understanding the multifaceted challenges of CL/P is essential for implementing targeted interventions and improving overall well-being. Further research is needed to assess the long-term effectiveness of interventions and identify novel approaches for enhancing mental health in this population.

Disseminated Varicella-Zoster and Acute Liver Failure in a Patient With Crohn's Disease on Systemic Immunosuppression
Authors: Shore Brandon , Fix Oren K. , Hansen Jonathan J.
Published: February 2025

Approximately 4 million cases of varicella-zoster occur annually, most of which are self-limited and managed conservatively with supportive care with or without oral valacyclovir. However, varicella-zoster rarely disseminates leading to severe systemic illness affecting multiple organs. Disseminated varicella-zoster causes significant morbidity and mortality, particularly in immunocompromised individuals. In this study, we report a case of a 27-year-old immunosuppressed man who developed disseminated varicella-zoster infection culminating in multiorgan failure and death. We review the epidemiology, risk factors, diagnosis, prevention, and treatment of disseminated varicella-zoster.

Published: February 2025

Se presentan resultados de una investigación sobre académicos que laboran en la Escuela Normal Bilingüe e Intercultural de Oaxaca (ENBIO). Esta institución, propone un modelo de formación de docentes vinculado a las lenguas y prácticas socioculturales del contexto de Oaxaca. El objetivo fue conocer el proceso de autoformación e identidad profesional de los académicos, a quienes se nombran como formadores de docentes, vinculado a su proyecto educativo. Así, a través del empleo de una metodología cualitativa, con perspectiva narrativa, se aplicaron 7 entrevistas en profundidad, que se analizaron siguiendo el método de la inducción analítica. Se encontró así un complejo entramado de distinciones y posicionamientos políticos y educativos de parte de los formadores, que se articulan con el interés de autoformarse y de comprometerse con su profesionalización, tanto como docentes, como investigadores. De igual forma, se identificó un creciente interés por fortalecer sus procesos identitarios, en la medida en que interactúan con sus estudiantes y pares académicos, así como en la constante reflexión sobre su propia autoadscripción identitaria y práctica docente. Para concluir encontramos la presencia de tensiones y conflictos al reconocerse como académicos de educación superior, y como promotores de un proyecto educativo con una perspectiva educativa “comunitaria”.
El libre desarrollo de la personalidad de las personas con discapacidad
Authors: Martínez Sánchez Nuria
Published: February 2025

El reconocimiento del principio de autonomía de la voluntad de las personas con discapacidad ha sido fruto de un proceso arduo, encumbrado por la Convención sobre los derechos de las personas con discapacidad (Nueva York, 2006), que supuso un cambio de paradigma en la concepción de la discapacidad, considerándola como una cuestión de derechos humanos. En España, como Estado Parte del instrumento internacional, se han sucedido reformas legislativas y pronunciamientos judiciales en distintas esferas de la personalidad de la persona con discapacidad, que pretendían acercarse a tal cometido, mas, no ha sido hasta la entrada en vigor de la Ley 8/2021, de 2 de junio, por la que se reforma la legislación civil y procesal para el apoyo a las personas con discapacidad en el ejercicio de su capacidad jurídica, que la normativa interna se ha impregnado del espíritu de la Convención. Bajo el respeto al libre desarrollo de la personalidad de la persona con discapacidad, paulatinamente se ha procedido a la sustitución de un sistema donde primaba la protección del interés superior de la persona con discapacidad, por otro, cuyo eje vertebral se basa en la autonomía de la voluntad de la persona. En este contexto, cobra gran importancia la figura del apoyo a la persona con discapacidad -especialmente aquellas medidas de carácter voluntario, diseñadas por la propia persona-, que, en cualquier caso, deberá respetar su voluntad, deseos y preferencias. De acuerdo con lo expuesto, se aborda en la última parte de esta monografía, la evolución en el derecho de autodeterminación de la persona en el ejercicio de ciertos derechos fundamentales que han experimentado grandes cambios hasta alcanzar esta finalidad.

Authors: Paché Gilles
Published: February 2025

This article offers a fresh analysis of 15th-century maritime explorations through the lens of large-scale project management. By detailing the critical stages of these expeditions, from shipbuilding and recruitment to provisioning essential supplies, it highlights the ingenuity, meticulous planning, and organizational expertise of navigators in the face of extreme challenges. The author explores the efficient management of scarce resources, such as water and food, and examines how adaptability to unexpected events—storms, diseases, navigational errors, and equipment failures—enabled explorers to overcome the hardships of long ocean crossings. In a unique and thought-provoking manner, the article draws parallels between the logistical practices of 15th-century navigators and those used in managing complex 21st-century projects. This cross-disciplinary approach underscores the continued relevance of historical lessons for addressing modern logistical challenges, particularly in uncertain, volatile, and turbulent environments. Ultimately, the article stresses the importance of ethics in large-scale project management, reminding scholars that innovation and progress must prioritize human dignity, environmental sustainability, and long-term social responsibility.
Cardinality Estimation for Having-Clauses

Published: February 2025

We present several methods for estimating the result cardinality of single table queries with a having clause. More specifically, we provide cardinality estimates for predicates using the aggregate functions count(*), sum(B), avg(B), min(B), and max(B). We do so for queries with and without a where-clause. Finally, we show how to handle conjunctions and disjunctions in the having-clause.
Chameleon: A Heterogeneous and Disaggregated Accelerator System for Retrieval-Augmented Language Models
Authors: Jiang Wenqi , Zeller Marco , Waleffe Roger , Hoefler Torsten , Alonso Gustavo
Published: February 2025

A Retrieval-Augmented Language Model (RALM) combines a large language model (LLM) with a vector database to retrieve context-specific knowledge during text generation. This strategy facilitates impressive generation quality even with smaller models, thus reducing computational demands by orders of magnitude. To serve RALMs efficiently and flexibly, we propose
Chameleon
, a heterogeneous accelerator system integrating both LLM and vector search accelerators in a disaggregated architecture. The
heterogeneity
ensures efficient serving for both inference and retrieval, while the
disaggregation
allows independent scaling of LLM and vector search accelerators to fulfill diverse RALM requirements. Our Chameleon prototype implements vector search accelerators on FPGAs and assigns LLM inference to GPUs, with CPUs as cluster coordinators. Evaluated on various RALMs, Chameleon exhibits up to 2.16× reduction in latency and 3.18× speedup in throughput compared to the hybrid CPU-GPU architecture. The promising results pave the way for adopting heterogeneous accelerators for not only LLM inference but also vector search in future RALM systems.
LLM-R

: A Large Language Model Enhanced Rule-Based Rewrite System for Boosting Query Efficiency
Authors: Li Zhaodonghui , Yuan Haitao , Wang Huiming , Cong Gao , Bing Lidong
Published: February 2025

Query rewrite, which aims to improve query efficiency by altering an SQL query's structure without changing its result, has been an important research problem. In order to maintain equivalence between the rewritten query and the original one during rewriting, traditional query rewrite methods always rewrite the queries following certain rewrite rules. However, some problems still remain. First, existing methods of finding the optimal choice or sequence of rewrite rules are still limited and the process always costs a lot of resources. Methods involving discovering new rewrite rules typically require complicated proofs of structural logic or extensive user interactions. Second, current query rewrite methods usually rely highly on DBMS cost estimators which are often not accurate. In this paper, we address these problems by proposing a novel query rewrite method named LLM-R
2
, which leverages a large language model (LLM) to recommend rewrite rules for a database rewrite system. To further enhance the inference ability of the LLM in recommending rewrite rules, we train a contrastive model using a curriculum-based approach to learn query representations and select effective query demonstrations for the LLM. Experimental results show that our method significantly improves the query execution efficiency and outperforms the baseline methods. In addition, our method exhibits high robustness across different datasets.

Influenza infections are often complicated by secondary bacterial infections such as MRSA pneumonia, which increase morbidity and mortality. Viral infections lead to an inflammatory response that includes elevated levels of IL‐6 and interferons. IL‐6 activates the JAK/STAT signaling pathway, amplifying downstream inflammation. Given the clinical efficacy of the JAK inhibitor baricitinib in reducing disease severity in COVID‐19, we evaluated its impact in a murine model of influenza, MRSA, and post‐influenza MRSA pneumonia. Additionally, because IL‐6 inhibitory therapies have improved outcomes during COVID‐19, we evaluated the impact of IL‐6 deletion on post‐influenza MRSA pneumonia. In our studies, baricitinib effectively inhibited the JAK/STAT pathway in the lungs, as demonstrated by decreased interferon‐stimulated genes (ISGs) and STAT3 phosphorylation. Despite this inhibition, baricitinib did not cause a global suppression of cytokines. Notably, baricitinib treatment did not impair either antiviral or antibacterial host immunity, inflammatory cell recruitment, or lung tissue injury. IL‐6 deficiency did not alter weight loss, inflammatory cell recruitment, or bacterial burden during post‐influenza MRSA pneumonia. These findings suggest that both JAK inhibition via baricitinib and IL‐6 deletion do not enhance host defense or limit tissue injury in murine models of influenza and post‐influenza MRSA pneumonia.

Between core and periphery: the development in English of a modal adverb, an evaluative adverb and a discourse connector
Authors: Lewis Diana
Published: February 2025

In recent discourse approaches to the peripheries, sentence adverbs have received less attention than categories such as pragmatic markers or discourse connectors. This study compares the development of sentence adverbs and discourse connectors via a case study of evidential apparently, evaluative sadly, and discourse-connector instead. These expressions occur in present-day English in all three ‘peripheral slots’. The study shows that the three expressions evolved into peripheral stance expressions via similar mechanisms, the developments being favoured by occurrence in constructions which appear to provide ‘bridging contexts’. The expressions are viewed in the light of two models of the development of such peripherals: Grammaticalization theory and Diachronic Construction Grammar. The findings point to some compatibility with a discourse-prominence-based approach to grammaticality and some compatibility with a model of productivity within a higher-level modification schema. Apparent regularities in the diachronic development, together with parallels between sentence modifiers and constituent modifiers, and synchronic relations between the constituent source items and the emergent peripheral items, suggest that the ‘boundary’ between core and periphery is both permeable and gradient rather than clear-cut.

Published: February 2025

Cr/Co-MOFs were synthesized via a solvothermal method using chromium acetate and cobalt chloride hexahydrate as metal ions, and trimeric acid as the organic ligand. The structures of Cr/Co-MOFs were characterized using Fourier infrared spectroscopy, X-ray diffraction, and scanning electron microscopy techniques. These Cr/Co-MOFs were used for removing organic contaminants in wastewater treatment. Fleroxacin and Rhodamine B (RhB) were specifically selected as target molecules in this study to evaluate the removal efficiency based on the mass of Co/Cr-MOFs, concentrations of organic contaminants, and adsorption time. Experimental findings indicated that at a Co/Cr-MOFs dosage of 100 mg, with initial concentrations of Fleroxacin (30 ppm) and RhB (20 ppm), removal efficiencies achieved were 95% and 99%, respectively. Within a timeframe of 5 h, Co/Cr-MOFs attained adsorption capacities amounting to 269.6 mg·g−1 for fleroxacin and 289.5 mg·g−1 for RhB. The interaction between Co/Cr-MOFs and fleroxacin, as well as RhB, is primarily attributed to factors such as pore size, hydrogen bonding, electrostatic charge, and π–π interactions. Moreover, theoretical analysis corroborated these experimental results by demonstrating conformity between the adsorption process and both second-order kinetic model equations alongside Langmuir isotherm model equations. Collectively, the experimental data combined with theoretical investigations underscore the practical significance associated with employing Co/Cr-MOFs for effective eradication of organic pollutants.

Published: February 2025

Additive manufacturing techniques have made it possible to create lighter and stronger lattice structures with intricate repeating geometric patterns which can be utilized for various industrial applications. Although several studies have reported on the effects of lattices with varying geometry on mechanical properties, fewer studies have investigated the effects of post-processing parameters on mechanical properties of these lattices. As such, this study investigates the effects of solid fraction of octet truss-based lattices and the effect of heat treatment on the mechanical properties of 3D printed octet truss lattices. Experimental findings revealed that Young’s Modulus and strength of lattices were enhanced upon heat treatment where tensile strength and stiffness of lattices with 40 % solid fraction improved by 20.55 % and 29.11 % respectively. Besides, it was found that the lattices without and with heat treatment obeyed the Ashby’s classic scaling law reasonably well for both modulus-density and strength-density relationship.
Influence of the viscosity of polymer melts on the coextrusion process based on wall slip conditions
Authors: Deng Xiaozhen , Chen Tianrong , Xiao Bing , Ren Zhong , Tang Gang , Xu Fang , Yan Xiaoxiao
Published: February 2025

Three-dimensional viscoelastic flow numerical models for the polymer coextrusion process were established on the basis of two different wall conditions and solved via finite element methods. The influence of polymer melt viscosity on the coextrusion process was investigated by analyzing die swell, melt interlayer interface stability and flow field distribution under two different wall slip conditions, namely, sticky adhesive condition and fully slip non adhesive condition. The results indicate that in the traditional coextrusion process with sticky adhesive condition, the die swell, interface stability and flow field distribution change with the melt viscosity, but the effects of the shell melt viscosity differ from those of the core melt viscosity. The die swell, interface offset degree and radial flow strength (orthogonal to the flow direction) increase with increasing shell melt viscosity and decrease with increasing core melt viscosity. The die pressure drop, shear rate and first normal stress difference increase with increasing shell or core melt viscosity, but the influence of the shell melt viscosity is much greater than that of the core melt viscosity. In the gas-assisted coextrusion process with fully slip non adhesive condition, the die swell, interface stability and flow field distribution are not affected by the viscosity of both polymer melts which means that the flow behavior in the coextrusion channels is independent of the polymer viscosity. There is no die swell or interface deviation phenomenon, nor any melt radial flow. The die pressure drop, shear rate and first normal stress difference are close to zero, except in the close vicinity of the die inlet. This approach not only ensures product quality but also solves the problem of material selection for polymer coextruded products. In addition, the goal of energy conservation and consumption reduction has been achieved, and the energy savings and consumption reduction effects are particularly significant for high-viscosity melts.
Temperature and pups influence daytime roosting behavior of the great fruit-eating bat, Artibeus lituratus, in an urban southern Brazilian habitat

Published: February 2025

Urbanization affects animal behavior, making ethology crucial for understanding its full impact. Artibeus lituratus is the most captured bat species in urban environments in Brazil, yet its ethology has never been studied in the country. Furthermore, there is much to be uncovered about the roles temperature and offspring play in influencing bat behavior. Thus, this study aimed to analyze the behavior of a group of roosting A. lituratus, and to test the influence of temperature and presence of offspring on their behaviors. A group of A. lituratus was observed roosting under palm leaves, on the Campus of Universidade do Extremo Sul Catarinense. Ad libitum sampling was used for behavior description, whereas Scan sampling was used to analyze the activity patterns and test the influence of temperature and offspring. Sixteen behaviors were distinguished. The bats were observed during daytime, and were the most active between 09:00 and 16:00, and lowest at 07:00, 8:00, and 17:00. Ambient temperature was positively correlated with behaviors “active” and “self-grooming”, and negatively correlated with “inactive”. “Allogrooming” was more abundant when offspring were present. This study provides the first ethological insights into A. lituratus in Brazil, emphasizing the roles of temperature and offspring in shaping their behavior.

Published: February 2025

Objectives

PCSK9 is critical in cholesterol homeostasis and anti-tumor immunity modulation. This study aims to investigate PCSK9’s role in HER2-positive breast cancer (BC) as a potential prognostic marker.

Methods

The impact of PCSK9 on HER2-positive BC was analyzed by virtue of data from The Cancer Genome Atlas (TCGA). Moreover, PCSK9 expression in tumor cells from 92 HER2-positive patients was assessed through immunohistochemistry (IHC). Then, it was found that this expression was correlated with various clinicopathological parameters including histological grading, hormone receptor (HR) status, and patient survival.

Results

PCSK9 expression positively correlated with pathohistological grading and hormone receptor status, but negatively with patient survival. GSEA showed low PCSK9 expression groups enriched in immune-related pathways, while high expression groups favored coagulation pathways. CIBERSORT analysis revealed a notable negative association between PCSK9 expression and γδ T cells, suggesting PCSK9’s role in modulating tumor microenvironment (TME) immune reactivity. Low PCSK9 expression was associated with a more favorable response to neoadjuvant therapy in patients.

Conclusions

PCSK9 expression in HER2-positive BC is a significant prognostic indicator, with higher levels related to worse clinical outcomes. These results suggest PCSK9’s potential utility in predicting treatment responses and guiding therapeutic strategies for HER2-positive BC patients.
Die Energiewende als gesellschaftliche Transformation: Potenziale der Zivilgesellschaft nutzen

Published: February 2025

Das Gelingen der Energiewende wird maßgeblich von dauerhafter Akzeptanz und Unterstützung in der Bevölkerung abhängig sein. Dieses Papier untersucht das Potenzial von Energiegenossenschaften, zur Förderung dieser Akzeptanz und zur Mitgestaltung der Energiewende vor Ort beizutragen. Die Ergebnisse zeigen eine Vielzahl an gesellschaftlichen Mehrwerten des genossenschaftlichen Modells, die in energiewirtschaftlichen Diskussionen jedoch häufig vernachlässigt werden. Gleichwohl stehen Energiegenossenschaften vor mehreren Herausforderungen, wie dem Druck zur Professionalisierung, einem Mangel an politischer Unterstützung und einer noch zu geringen Vielfalt innerhalb der Mitgliedschaft. Darüber hinaus zeigt sich die Notwendigkeit, dass sich Kommunen künftig stärker als bislang als Netzwerke von Akteuren unterschiedlicher gesellschaftlicher Sektoren begreifen, um gesellschaftlichen Wandel gemeinsam zu gestalten.

Objective: The aim of this study was to analyse Mexican physical education teachers' level of knowledge of prevention and safety recommendations for returning to classroom instruction after COVID-19 confinement, and to determine whether there were differences according to gender and type of professional training. Methods: A total of 669 teachers (Mage = 40.33 years, SD = 10.26) responded to an ad hoc questionnaire. Results: The results showed high mean scores for prevention and safety measures, with hygiene recommendations being the highest (M = 6.52), while the use of technology was the lowest (M = 5.32). Significant differences were only found for professional training in hygiene recommendations (p < .05; Hedges' g = 0.09), while there were no statistically significant differences according to gender in any of the factors. Conclusion: There seems to be a broad recognition of safety measures for COVID-19 prevention by the teachers participating in this research, however, studies with different methodologies are needed to confirm these findings.
La especialización temprana en el deporte: es necesario cambiar el paradigma de atleta-máquina
Authors: Rodríguez Sebastián , Rodríguez-Jaime María Fernanda
Published: February 2025

Introduction: Early specialization in sports is a highly controversial and debated topic throughout history, it involves designating an individual to a particular sport discipline prematurely or in an anticipatory manner, typically occurring at very young ages. Objective: To question the practice of early specialization in children, both boys and girls, through the development of arguments and reflections. Development: Rather than benefiting athletes, this practice favors external agents with private monetary interests. Although at first glance, it may seem harmless or even beneficial, it is not truly what it appears to be. Multiple negative aspects have been evidenced, which can jeopardize the integrity of children, causing physical and psychological issues, violating their rights, and leading to early abandonment and distancing from exercise and sports. Conclusions: Coaches and physical educators should emphasize aspects of the mind, understand athletes’ perceptions and sensations, respect their preferences and tastes, and avoid manipulation and persuasion. Therefore, young people should be allowed to explore multiple sports disciplines, thereby fostering sports as a space for learning and social development rather than mere competition.

Published: February 2025

When humans engage with video, their brain and body interact in response to sensory input. To investigate these interactions, we recorded and are releasing a dataset from N=178 participants across five experiments featuring short online educational videos. This dataset comprises approximately 110 hours of multimodal data including electrocardiogram (ECG), heart rate, respiration, breathing rate, pupil size, electrooculogram (EOG), gaze position, saccades, blinks, fixations, head movement, and electroencephalogram (EEG). Participants viewed 3-6 videos (mean total duration: 28±5 min) to test attentional states (attentive vs. distracted), memory retention (multiple-choice questions), learning scenarios (incidental vs. intentional), and an intervention (monetary incentive). Demographic data, ADHD self-report (ASRS), and working memory assessments (digit span) were collected. Basic statistics and noteworthy effects: increased alpha power in a distracted condition, broadband EEG power increases from posterior to anterior scalp, increased blink-rate, and decreased saccade-rate in distracted and intervention conditions. All modalities are time-aligned with stimuli and standardized using BIDS, making the dataset valuable for researchers investigating attention, memory, and learning in naturalistic settings.

This study investigates the conservation assessment of a polychrome sculpture from the 17th century depicting San Diego de Alcalá, whose origin and workshop remain unknown. Traditionally characterized by specific iconographic elements such as bread and keys, the examined statue deviates from these norms. Initiated by the Diocesan Mitre in Duque de Caxias, the assessment focused on the structural integrity and pigment composition of the sculpture. Using techniques of Computed Tomography (CT), Digital Radiography (DR), and X-ray Fluorescence (XRF), the sculpture underwent a comprehensive analysis. Portable equipment, such as the ICM CP120B X-ray tube and DXR 250U-W flat panel detector, facilitated both CT and DR scans. The CT scan was segmented due to detector size limitations, using an 80 kV, 1 mA X-ray tube to capture 360 images per segment. XRF analysis focused on 12 specific points, employing the Bruker Tracer III-SD with a rhodium X-ray tube and silicon detector, operating at 40 kV and 35 µA for 60 seconds per point. Imaging techniques revealed imperfections, restorations, and structural details, including high-density fillings and embedded nails in the sculpture. XRF analysis identified characteristic elements of historical pigments, along with indications of more recent restorations, possibly involving 20th-century pigments. These findings significantly enrich the understanding and conservation strategies of this religious artwork, providing valuable insights into its construction history and restoration.

The aim of this work was to establish the possibility of Lemna minor usage to improve the efficiency of wastewater treatment from nitrogen and phosphorus compounds.

Due to their pollution resistanse, Lemna minor is often used for wastewater remediation. It’s capability of absorption and transformation of various compounds, promotes the deposition of suspended matter, saturates water with oxygen, intensifies the purification processes.

Due to the rapid growth rate, duckweed absorbs a large amount of pollutants, thereby purifying water from them. However, there is insufficient data and information on the efficiency of nitrogen and phosphorous compounds extraction by Lemna minor wastewater. That is why the research direction was to determine the efficiency of wastewater treatment from biogenic nitrogen and phosphorus compounds by higher aquatic plants of Lemna minor.

The necessary conditions for cultivation of higher aquatic plants of Lemna minor in autumn and winter were established. The efficiency of using duckweed of different mass for purification of waste water from biogenic compounds of nitrogen and phosphorus was investigated. The usage of duckweed together with other higher aquatic plants to investigate wastewater from biogenic nitrogen and phosphorus compounds was investigated.

It was found that the efficiency of sewage treatment in the autumn-winter period should adjust the mode of illumination and temperature regime.

The use of multifunctional nanosystems in medicine and research is of contemporary interest.

Aim. The purpose of the work was to summarize publications on the prospects of creating and using nanocontainers based on curcumin (Cur). Cur fluorescence in nanoparticles (NP) makes it possible to investigate the distribution of fluorescent and non-fluorescent components, significantly accelerating the study and implementation of drugs in practice. Particular attention is paid to the use of hydrophobic substances in NP, to penetrate into a living cell.

Understanding the interaction of NP with living cells is extremely important when these particles are used to transport and deliver water-insoluble drugs to cells. Cur is one of the drugs with various and very promising pharmaceutical effects, it is poorly soluble in aqueous media, and the use of nanocarriers is an effective way to significantly increase its bioavailability. Cur has its own fluorescence, which enables to use it in multifunctional fluorescent nanosystems, for example, with Pluronic® micelles.

The use of the fluorescence method makes it possible to trace the stages of interaction of Cur-loaded NP with cultured cells and their localization in cell organelles.

With this approach, nanoscale dynamics of drug distribution and stability is observed over time.

Conclusions. The main conclusion is that for unstable in the aquatic environment drugs such as Cur, it is necessary to use the most hydrophobic nanostructures without traces of water, which include the nuclei of Pluronic® micelles. This method makes it possible to use other poorly water-soluble drugs.

A promising area of nanomedicine is the creation of complex bio-compatible nanomaterials based on several active drugs that reduce the toxicity of preparations to normal cells.

This article is devoted to the study of the influence of the chemical nature of the components of polyurethane matrices (PU) on their optical and viscoelastic properties in order to obtain polymer materials that combine several different functional properties: high transparency, effective UV protection and high damping ability. PU matrices with different chemical structures of diisocyanate (aliphatic (hexamethylene diisocyanate) or aromatic (toluylene diisocyanate)) and oligodiol (oligoether (oligooxypropylene glycol) or oligoester (oligodiethylene glycol adipate)) blocks were synthesized. PU matrices with different molecular weights of ester (800 and 1500) were synthesized too. It was established that all PU matrices have a fairly high (~90 %) transmission coefficient in the range of visible wavelengths and UV blocking. However, the range of UV absorption significantly depends on the PU components. Matrices based on aliphatic diisocyanate absorb UV up to 250–280 nm. The UV absorption of PU matrices based on aromatic diisocyanate, regardless of the nature of their oligoester component and its molecular weight, undergoes a shift to the long-wavelength region – up to 300–400 nm, which is due to the presence of aromatic rings. For PUs with an aromatic component, the highest absorption in the UV region is observed for PUs based on oligoesters, which is explained by the greater absorption ability of ester groups relative to ether ones. It was found that PU matrix based on oligoester has better elastic properties, but the PU matrix based on oligoether is characterized by a wider temperature range of effective damping. The replacement of aliphatic diisocyanate with an aromatic one shifts the area of effective damping of PU material towards positive temperatures. Therefore, by changing the nature of PU components, as well as the molecular weight of the PU oligoester component, it is possible to obtain transparent materials with a wide temperature range of effective damping in combination with high protection against UV radiation.

Purulent pericarditis (PPc) is a rare but clinically significant form of pericarditis that is typically associated with severe infection. Diagnosis is made by aspirating purulent fluid from the pericardial space, although cultures or gram stains of this fluid often yield negative results. Early detection and treatment are important in preventing severe complications such as cardiac tamponade, persistent infection, and the need for advanced therapies. This report describes the case of a 56-year-old man with multiple comorbidities, including diabetic ketoacidosis, COVID-19, and methicillin-sensitive Staphylococcus aureus (MSSA) bacteremia, who was diagnosed with PPc after developing early cardiac tamponade and undergoing successful pericardiocentesis.
DISHARMONY OF MASCULINE AND FEMININE PRINCIPLES IN GOGOL’S «VIY»: CHRISTIANITY VERSUS PAGANIZM
Authors: ZAIETS Olga , TYMCHENKO Vitaly
Published: February 2025

The article shows an example of the masculine and feminine principles disharmony on the basis of Gogol’s “Viy” analysis. The events described by Gogol are presented as the psychopathology of erotic life. The general context of this interpretation is the socio-cultural adoption of paganism and patriarchal Christianity. The article highlights the significance of pagan roots of Ukrainian culture, which is usually drowned out by the influence of Russian Orthodox chauvinism and is a factor in the revival of Ukrainian culture at the time of its genocide. “Viy” is an image of the patriarchal-church civilization, that has humiliated feminine virtues. Due to the supplanting of femininity, masculinity becomes wild, deviates to crazy destructiveness, men’s attitude towards women sinks into the subconscious darkness, women are demonized, and men behave in a mean, aggressive and insidious manner. The church temple is a symbol of a person, his or her desire to achieve spiritual growth, rebirth of divine heights. Gogol describes the temple as a place of death and emptiness - that is devoid of God and life. Viy is interpreted as a living nature force symbol, the one who is able to see in a person what person avoids to see and issues as alive - the deadness of the soul, which brings death to the living.Homa sees himself for the first time. But such a sudden, fatal, terrifying vision of someone from whom it is no longer possible to turn away, who until now he imagined as an unclean evil force, causes such a stormy attack of pangs of conscience that Homa cannot endure. The dirt falls, the earth returns to the earth, the dead bury the dead. Only the spirit flies to the heights to be reborn in the spring. Homa Brut did not use the chances to realize and surpass himself in this life.
