A história da arte mágica proposta por André Breton
Authors: Lino Sulamita Fonseca
Published: December 2024

Em 1957, três décadas após a criação do primeiro Manifesto Surrealista (1924), Breton publica L'Art Magique : Une Histoire de l'Art, obra na qual são retomados temas como o fascínio pelo mistério, pelo desconhecido e pelo maravilhoso. O livro consiste em um vasto levantamento de imagens, obras de arte e textos de autores que lidaram com o tema da magia em diversos campos do conhecimento, como o ocultismo, a antropologia, a filosofia e a literatura. Nesta obra, Breton retoma temas tratados nos escritos surrealistas anteriores, tais como o acaso, a espontaneidade e a oposição ao racionalismo. Contudo, todos eles agora são reconfigurados a partir da perspectiva da magia. Isso fez com que o autor retomasse os textos de Baudelaire, o debate acerca da arte primitiva e a maneira como o surrealismo abordou a questão da magia. Tendo em vista que L'Art Magique é uma obra com muitas referências, optamos, neste trabalho, por fazer uma apresentação geral do texto e  abordar as conexões entre o fazer artístico e a espontaneidade.

CALCULATION OF THE SEISMIC RESISTANCE OF THE START-UP AIR SYSTEM OF RDES
Authors: Bibik Tymofii , Ostapenko Ivan , Havrylʹchyk Dmytro
Published: December 2024

The earth beneath our feet is alive, even though it is a rocky planet. Despite the fact that geological activity cannot be felt, sometimes it manifests itself sharply and dangerously. Earthquakes and seismic phenomena are responsible for the transmission of these tectonic shocks and have forced people to be prepared for different situations with the oscillation of the earth's crust. Seismic shocks cause many dangerous phenomena: landslides and avalanches in the mountains, flood waves (tsunamis) on the shores of seas and oceans, cracks and liquefaction on the land surface.
Depending on the magnitude of the earthquakes, each year there are from one to two dozen earthquakes with a power of more than 7 points according to the Richter scale. How can the destruction of building equipment, disasters and deaths be prevented and what is "seismic resistance" is the question of our research.
In order to confirm that the equipment is guaranteed to perform its functions under seismic conditions, equipment qualification is performed. The assessment of the initial state of seismic qualification consists in comparing the seismic qualification characteristics with the seismic qualification requirements, as well as establishing the availability of information in the factory and project documentation regarding the fastening of the equipment, and allows to establish whether the qualification requirements presented in the process of seismic qualification were taken into account during development and staging for production, manufacturing and installation.
Seismic qualification characteristics are contained in the design documentation of equipment developers and manufacturers and can be specified in different forms: values of acceleration amplitudes; the intensity of the earthquake and the level of installation of equipment above the zero mark; test parameters, mechanical performance groups, etc.
If the qualification characteristics of the equipment meet the defined or calculated qualification requirements, then the qualification of such equipment for earthquake resistance is established.
THE INFLUENCE OF THE RESISTANCE OF THE NEUTRAL GROUNDING RESISTOR ON THE 20 KV VOLTAGE DISTRIBUTION MODES OF OPERATION
Authors: Kyryk Valerii , Buryak Anna
Published: December 2024

The article examines the impact of different modes of neutral grounding on the operating parameters of 20 kV distribution networks, in particular, the selection of the optimal resistor resistance for resistive neutral grounding. One of the main tasks is to improve the efficiency of distribution networks of the UES of Ukraine by switching from a voltage of 10 kV to 20 kV. This solution is aimed at reducing power losses, increasing the amount of transmitted energy and improving the operation of relay protection. In the context of such a transition, the choice of the method of grounding the neutral of the power transformer is particularly relevant, which significantly affects the reliability and safety of operation of electrical networks.
In the study, an analysis of the effect of resistive grounding of the neutral of the transformer on the operating characteristics of the 20 kV network was performed, as well as determination of the optimal value of the resistance of the resistor. The article presents the results of a comparison of a network with an isolated neutral and resistive grounding. The main operating parameters, such as short-circuit currents, overvoltages on undamaged phases, power losses and operation of relay protection, which have a significant impact on the stability and safety of network operation, are analyzed.
Modeling is performed using the PowerFactory software complex, which provides the ability to accurately reproduce the real operating conditions of electrical systems. To conduct the research, a simulation model of the distribution network was created based on a two-transformer 110/20 kV substation, which includes two sections with outgoing lines of different lengths and loads. Special attention was paid to the selection of the resistance of the neutral grounding resistor and its influence on network parameters. Four options were considered in the study: isolated neutral and resistive grounding with a resistance of 10 Ohm, 15 Ohm and 20 Ohm.
It was established that in order to ensure stable and safe operation of the distribution network, it is important to correctly choose the neutral grounding method. The best option is resistive grounding with a resistance of 15 Ohms, which allows you to reduce power losses, provides a sufficient level of currents for the effective operation of relay protection, and minimizes the risks of overvoltages on undamaged phases. This study is important for increasing the reliability of the operation of distribution networks and the security of electricity supply, especially in the context of the modernization of Ukraine's UES networks.
EFEITOS DA TOXICIDADE DO HERBICIDA NORTON® NA GERMINAÇÃO E CRESCIMENTO EM CAPSICUM ANNUUM
Authors: Do Carmo da Silva Ducilene , Gustavo Paulino Marcelo
Published: December 2024

Dos herbicidas mais utilizados no Brasil, as formulações combinadas com 2,4–D e Picloram como princípios ativos geram preocupações quanto ao resíduo final, que podem ser rios ou solos, impactando negativamente a saúde humana e ambiental. O objetivo deste estudo foi avaliar o efeito tóxico do herbicida Norton® com o uso de um organismo bioindicador vegetal Capsicum annuum. A toxicidade do pesticida foi avaliada através das concentrações  de 1, 3, 5, 10, 25, 50, 75 e 100%, com exposição de 7 dias. Quantificou-se o número de sementes germinadas e o comportamento de germinação durante o bioensaio. Às sementes germinadas, mediu-se o comprimento das raízes. As sementes foram transferidas para vasos contendo adulbo vegetal, e monitoras durante 4 meses. Houve efeitos tóxicos na germinação e crescimento radicular. Às sementes expostas às baixas concentrações, houve grande número de germinação, entretanto, com redução do comprimento radicular. Houve morte das plantas expostas ao herbicida, principalmente as submetidas as maiores concentrações. Nas plantas expostas a concentrações minimas do herbicida, houve alterações na morfologia foliar e crescimento da planta. Portanto, foi evidente que a diluição do pesticida, mesmo em baixas concentrações causam toxicidade e morte dos indivíduos a longo prazo.

Second Language Learners’ Age: A Case Study of Selected Non-native speakers of English
Authors:   University of Dundee, Oluwole Joshua
Published: December 2024

Debates on the ideal age to learn the English language as a second or foreign language continue to permeate the field of applied linguistics. While some research concludes that the earlier a learner is exposed to the target language, the better, others are of the opinion that later access to a second or foreign language might be more advantageous. Employing selected non-native speakers of English as a case study, this research attempts to examine both sides of the argument.

A qualitative research design was employed, using in-depth interview as the data gathering tool, with 4 participants. The findings of the study show that both earlier and later access to a second language tend to have unique benefits and shortcomings. While second language learning should be encouraged to start at earlier ages, adult learning should also be supported and promoted, as the maturity capacity can be advantageous in the learning process if appropriately harnessed.

Skin cancer is a disease that reflects most malignant neoplasms worldwide, whose rate of involvement has increased significantly in recent decades. Treatments that offer efficient results with attenuation of adverse reactions and greater patient compliance have been the subject of many systematic investigations. This review aims to qualitatively present published works that showed new strategies to increase the penetration power of natural substances through the skin in the topical treatment against skin cancer. In this sense, nanoengineering mechanisms, the iontophoresis technique, and photodynamic therapy using natural products (NP) contribute to new knowledge about substance carrier strategies in topical treatments against skin cancer.
The Sentinel Sleep Theory: Unweaving The Biological Function of REM Sleep
Authors: Spinassi Raffael
Published: December 2024

The biological function of rapid eye movement (or REM) sleep—one of the great mysteries of neuroscience—remains unknown. Here, I demonstrate that the biological function of REM sleep is to heighten brain alertness, significantly reducing the high vulnerability of deep sleep. Every organism with a nervous system must undergo deep sleep: a necessity that comes with substantial vulnerability. Deep sleep, by lowering alertness, compromises the organism's safety, putting its survival at risk. Therefore, REM sleep is a necessary adaptation for any organism that must sleep. My primary goal here is to present a comprehensive conceptual framework—supported by extensive empirical evidence—to connect numerous disparate empirical findings under a unified theory of the biological function of REM sleep. Additionally, I also provide a historical narrative to explain its origin and subsequent evolution. To test the theory I developed here, I drew on a substantial body of evidence and testable hypotheses derived from it. All 38 hypotheses capable of empirical verification were corroborated, revealing that the theory is widely corroborated. Furthermore, it also resisted numerous other attempts at refutation. Thus, the theory I elaborated here will advance theoretical neuroscience and change the way REM sleep research is planned and carried out.
Denoising X-ray Diffraction two-dimensional patterns by a Lattice Boltzmann Method
Authors: Ladisa Massimo
Published: December 2024

An X-ray Diffraction pattern consists of the relevant information (the signal) and the noisy background. Under the assumption that they behave as the components of a two-dimensional mixture (bicomponent fluid) having slightly different physical properties related to the density-gradients, a Lattice Boltzmann Method is applied to disentangle the two different diffusive dynamics. The solution is numerically stable, computationally not demanding and, moreover, it provides an efficient increase of the signal-to-noise ratio for patterns blurred by poissonian noise and affected by collection data anomalies (fiber-like samples, experimental setup, etc.). The model has been succesfully applied to different resolution images.

Authors: Cao Mingxuan , Xu Meng , Gao Yongqiao , Wang TianLei , Deng Anan , Liu Zhenyu
Published: December 2024

Aiming at the anti-swing control problem of shipboard cranes with limited movement space in actual work, a nonlinear anti-swing controller based on asymmetric Barrier Lyapunov Functions (BLF) is designed. First, model transformation mitigates the explicit effects of ship roll on the desired position and payload fluctuations. Then, a newly constructed BLF is introduced into the energy-based Lyapunov candidate function to generate nonlinear displacement and angle con-straint terms to control the rope length and boom luffing angle. Among them, constraints with positive bounds are effectively handled by the proposed BLF. For the swing constraints of the unactuated payload, a carefully designed relevant constraint term is embedded in the controller by constructing an auxiliary signal, and strict theoretical analysis is provided by utilizing reduc-tion to absurdity. In addition, this auxiliary signal fully considers the boom luffing velocity and payload swing angle-related information to enhance swing suppression performance. Finally, the asymptotic convergence of the system is proved through rigorous stability analysis, and simula-tion comparison results verify the effectiveness and salient features of the proposed controller.

Energy efficiency is a critical concern for cloud computing infrastructures, especially for large-scale web platforms with extensive computational demands. This paper presents a framework integrating dynamic resource allocation, workload optimization, and renewable energy utilization to enhance energy efficiency without compromising performance or Quality of Service (QoS). By leveraging machine learning models for predictive resource management and bio-inspired algorithms for workload distribution, the framework achieves a 20% reduction in energy consumption, 85% resource utilization, and 95% QoS compliance. Additionally, it relies on renewable energy for 60% of operations, contributing to sustainability. The framework was evaluated using real-world datasets and simulated environments, demonstrating its scalability and adaptability to diverse workloads. This study addresses challenges in balancing energy efficiency and performance in cloud infrastructures, providing insights into intelligent optimization techniques and sustainable practices. Future work will extend the framework to emerging paradigms like edge and fog computing, ensuring relevance in next- generation distributed systems.
Is dUTPase Enzymatic Activity Truly Essential for Viability?

Published: December 2024

The study of protein enzymatic activities has always been a significant area of scientific and industrial research. The key stages typically undertaken in the characterization of a given enzyme family include establishing the mechanism of catalysis, measuring kinetic parameters, determining structural organization and the architecture of the catalytic center, and subsequential classification. In this review, we address these classical aspects concerning the dUTPase enzyme family, specifically focusing on spatial structure and catalytic activity, while also providing an overview of certain additional functional properties exhibited by some members of this family. The fact of existence of such extra functions raises questions about the reasons for this functional duality. Based on the information known in the literature and our previous research, in this review we conclude that the enzymatic activity of dUTPases suplements other functions independent of the hydrolysis reaction occurring in the catalytic center. In this context, dUTP acts not just as a substrate, but as a signaling molecule, whose binding facilitates the realization of a distinct, non-enzymatic role of dUTPases.

Published: December 2024

To address the issues of severe information loss and suboptimal fusion effects in multimodal feature extraction and integration during multimodal point cloud shape completion using autoencoder structures, which results in difficulty in balancing local and global feature information of point clouds and significant loss of structural information in images, this paper proposes a LiDAR point cloud multi-scale completion algorithm guided by image rotation attention mechanisms, with a focus on the study of feature extraction from point clouds and images. The network employs an encoder-decoder structure, where the image feature extractor in the encoder utilizes rotation attention mechanisms to enhance the capability of image feature extraction. The point cloud feature extractor employs multi-scale methods to improve the global and local information of point cloud features and employs multi-level self-attention mechanisms to achieve multimodal feature fusion. The decoder then employs a multi-branch completion method to accomplish the point cloud completion task, with the network trained using chamfer distance guidance. Comparatively, our algorithm outperforms eight related algorithms on the ShapeNet-ViPC dataset across various metrics. Compared to the state-of-the-art network XMFnet, the category-averaged Chamfer Distance (CD) value is reduced by 11.71\%. The proposed algorithm in this paper can better extract image structural information, and the feature extraction of in-complete point clouds can consider both global and local information. Furthermore, through multi-level progressive feature fusion, the algorithm enhances the complementarity of information between different modalities, leading to more accurate point cloud completion results.

A novel sequential one-pot bimetallic catalytic system combining Fe(III)-catalyzed alkynylation and a Rh(I)-catalyzed [2+2+2] reaction was successfully developed. The σ-Lewis acid properties of iron (III) and the π-Lewis acid properties of rhodium (I) catalysts were unified in an unprece-dented intermolecular alkynylation/cyclotrimerization one-pot process. Using this unique Fe/Rh bimetallic relay catalytic system, a variety of benzo and pyrridinoisoindolinones derivatives were obtained under mild conditions from easily available N-(propargyl) hydroxy aminals, as the simplest N-acyliminium ion precursors, and several alkynes.

Published: December 2024

To investigate the impact of different exogenous plant hormones on the root phenotype, plant morphology, and endogenous hormone levels of Malus hupehensis seedlings, hydroponically cultivated seedlings were treated with different plant hormones, including IAA, IBA, GA, 6-BA, BR, and MeJA. The development of the plants was meticulously observed, and morphological indices (including the number of lateral roots, root length, root surface area, root volume, plant height, and stem diameter) as well as endogenous hormone levels (including ZR, IAA, ABA, GA1+3, JA, and BR) were measured. The results showed that auxins facilitated the lateral root development of M. hupehensis, whereas 6-BA impeded it. Compared with the control group, IAA and IBA enhanced the lateral root number, whereas 6-BA reduced it. BR was found to stimulate the development of plant height and stem diameter in M. hupehensis. Concurrently, the application of exogenous hormones also exerted influence on endogenous hormone levels. For instance, after treatment with 0.1mg L-1 BR, the levels of ZR, IAA, and GA1+3 in the lateral roots of M. hupehensis seedlings were markedly reduced, whereas after 0.1mg L-1 IAA treatment, the IAA and BR levels in the roots significantly increased, with concurrent notable decreases in ABA and GA1+3 levels. These findings provide a theoretical basis for the hormonal regulation of lateral root development in M. hupehensis.

This article investigates the possibilities of the Metaverse in the creation of trade fair stands 1 for the exhibition of products and services associated with the textile sector, particularly upholstery 2 fabrics, with the aim of expanding the possibilities of interrelation between manufacturers and 3 customers. This study is part of a broader research that analyses the applications of the Metaverse 4 in Industry 5.0, improving design aspects and interactions with users. The applied methodology 5 proposes to expand the possibilities of a physical stand and to impose itself as an alternative exhibition 6 for the promotion and sale of these textile products. To create the digital environment, the Metaverso 7 platform, Spatial.io and its Spatial Toolkit have been used, which has a Unity template, allowing 8 for more efficient editing of scenarios in their three-dimensional aspects. The template used has 9 limitations imposed by Spatial because it does not have the full potential of Unity, however, some 10 restrictions have been overcome by resorting to good programming so that the user can combine 11 fabrics from a texture selector. The authors of this article have designed a virtual stand following the 12 client’s indications by applying compositional resources based on simple structure systems, according 13 to the basic design theories of modernity. This design was tested at the Habitat Fair in Valencia 2024, 14 and the result shows the potential of these new technologies at the service of the textile sector.

Authors: Kanagaraj Uthaya Kumaran , Kulkarni Tapas , Kwan Eddie , Bone Jeffery , Shivananda Sandesh
Published: December 2024

Background/Objectives: The numerical risk of bronchopulmonary dysplasia (BPD) and/or death could be estimated using the National Institute of Child Health and Human Development (NICHD) BPD outcome estimator 2022 in extremely low gestational age (ELGA) infants during the first 4 weeks of life to facilitate prognostication, and centre specific targeted improvement interventions. However, 2022 NICHD BPD outcome estimator’s performance in Canadian setting has not been validated. Our objective is to validate the NICHD BPD outcome estimator 2022 in predicting death and or moderate to severe BPD at 36 weeks in less than 29 weeks infants admitted to NICU. Methods: A retrospective observational study (March 2022–August 2023) was conducted on both inborn and outborn preterm infants excluding neonates with major congenital anomalies. Infants were classified into five groups based on the predicted risk of death or moderate-to-severe BPD (<10%, 10-20%, 20-30%, 30-40%, ≥50%) followed by noting observed outcomes from unit’s database. A Receiver Operating Characteristics (ROC) curve was used to assess the accuracy of the NICHD BPD outcome estimator 2022, with an area under curve (AUC) >0.7 defined a priori as an acceptable predictive accuracy for local use. Results: Among 99 infants included, 13 (13.1%) died, and 40 (40.4%) developed BPD. Median gestational age was 26 weeks, and median birth weight was 914 grams. Twenty-three infants (23.2%) received postnatal steroids. The AUC values for death or moderate to severe BPD on days 1, 3, 7, 14, and 28 were 0.803, 0.806, 0.837, 0.832, and 0.843, respectively. The AUC values for moderate to severe BPD alone on those days were 0.766, 0.746, 0.785, 0.807 and 0.818 respectively. Conclusions: The 2022 BPD estimator accurately predicted the death and /or moderate to severe BPD on Days 1, 3, 7, 14 and 28 of life. This tool could serve as a valid adjunct to facilitate discussion between clinicians and families on initiating time-sensitive targeted interventions to prevent or alter the course of BPD.

Published: December 2024

Monitoring creatinine levels in urine helps to recognize kidney dysfunction. In this research we have developed a photocurable membrane for the detection of serum creatinine. Using a system based on field-effect transistors, we carried out comparative tests of creatinine recognition in solutions prepared in different matrices. The device was able to detect creatinine in water, synthetic urine and pH 4 buffer from the lowest concentration tested (3 mmol L-1), covering values between 21 % and 31 % within the range of creatinine variation for healthy individuals (3-27 mmol L-1) with measurement linearity of 97 %. The LOD achieved in the test was 1.31 mmol L-1 under flow conditions. With LOQs between 4.34 mmol L-1 and 24.13 mmol L-1. The system performed very well in the measurements, with hysteresis ranging from 1.1 % to 8.6 % for the different matrices tested. Up to 90 days after manufacture, the sensor still maintained more than 70% of its initial response, even when used periodically during the first week and when stored unused at -18 ºC, it was able to maintain 96.7 % of its initial response. The device used in the flow test only had a useful life of three days due to membrane saturation, which was not reversible. In the interference test, the membrane was also shown to respond to the urea molecule, but in a different response window, which allowed the contributions of the two molecules to be differentiated. EGFETs can be used to identify variations in creatinine concentration and can help in therapeutic decision-making.

Extremal principles of irreversible thermodynamics are considered, such as the principles of minimum and maximum entropy production in an analytically exactly solvable model of a Rayleigh gas with and without particle sources. It is shown that in an isolated system, during relaxation to an equilibrium state, the entropy production is minimal. In a system with sources, during relaxation of an equilibrium state to a nonequilibrium state, the entropy production is maximum. The concepts of free and forced the relaxation are introduced. Free relaxation is the transition of a system from a state far from equilibrium to a state close to equilibrium. Moreover, at each moment of relaxation, entropy production is minimal, i.e. the principle of minimum entropy production is fulfilled. During forced relaxation, the system moves from a state close to equilibrium to a state far from equilibrium, in which case the entropy production is maximum. It is shown that the principles of minimum and maximum entropy production are variational principles of irreversible thermodynamics under various thermodynamic conditions.

Background: Sleep deprivation is a global health concern with clinical, economic, and social consequences. Studies conducted in Asia reported a significant prevalence of poor sleep quality. There is a paucity of data on sleep deprivation in the Middle East and UAE, in particular. We set out to determine the prevalence of sleep deprivation and its association with physical and mental health in UAE. Methods: We used a cross-sectional design with a sample size, estimated using StatCalc software. Data collection tool was a survey instrument that we developed and then validated. Data analysis was done using Statistical Package for Social Sciences (SPSS). Results: Nearly 51% of the participants were younger than 25 years. Sleep deprived participants reported experiencing headaches frequently (25%) with a p-value of 0.07, with 22% having feelings of depression and lack of concentration with a p-value of 0.016. Discussion: sleep deprivation showed an association with depression/hopelessness but not statistically significant. However, sleep-deprived individuals may be more prone to physical and mental health conditions in the long term, requiring further research. Conclusion: This study establishes a link between sleep deprivation and physical/mental health outcomes, requiring further research. The willingness of many sleep-deprived individuals to seek help offers a promising avenue for intervention. Policymakers ought to integrate sleep health into broader public health policy.
Effect of Aging and Obesity on Parameters of Insulin, T4/T3 Ratios, Metabolic Rates, Sirtuins and Longevity in Congenic LA/Ntul//-cp (Corpulent) Rats

Changes in thyroidal activity occur in aging, where they typically exhibit a U-shaped curve for plasma TSH concentrations, with variable responses in other parameters of thyroidal function and peripheral physiological actions and their pathophysiologic sequelae. The LA/Ntul//-cp rat strain, developed from a cross between a Koletsky Rat and an NIH longevity-prone LA/N strain of unknown origin exhibits one of the longest life spans of the various rodent strains that express a trait for early onset obesity in association with impairments in sympathetic and thyroidal components of non-shivering thermogenesis, insulin resistance and energy metabolism. To determine the effects of aging and obesity from adolescence through much of the projected lifespan of the obese phenotype, groups of congenic lean and obese female LA/Ntul//-cp rats were studied from 4 until 24 months of age. Measures of Resting Metabolic rates (RMR), fasting plasma insulin and glucose, T3, T4, plasma half-life of T4, and computation of T4/T3 ratios were determined as an indication of the capacity for deiodination of T4 to T3 in peripheral tissues and its cumulative effects on RMR. Body weight of obese >>> lean at all ages studied. Plasma Insulin was significantly elevated in the obese phenotype, and decreased with advancing age, while plasma glucose remained within the normal fasting range in all rats of both phenotypes. RMR of lean > obese at all ages studied and decreased with advancing age in both phenotypes. Liver T4-5’ deiodinase activity of lean > obese at all ages studied. Plasma T4/T3 ratios decreased with aging in both phenotypes, with the greatest decrease in the obese phenotype. The T1/2 of 131I-T4 was over 40 % longer in the obese phenotype littermates at 4 months of age (p=< 0.01).These results suggest that conversion of T4 to T3 in peripheral tissues in association with attenuation of hyperinsulinemia contributes to decreases in RMR with aging and is further decreased in the obese phenotype, thereby decreasing the quantifiable availability of tissue T3 mass for thyroidal actions at the genomic level, including decreases in harmful reactive oxygen species (ROS) and other entities as products of intermediary metabolism. Thus, the progressive decreases in plasma insulin and deiodination-mediated activation of T4 may represent a longevity attribute via decreases in resting metabolic rates, and in an associated attenuation of free radical generation and other metabolic factors of aging and longevity in this strain.

Microbiota could be of interest in the diagnosis of Colorectal and Non-small Cell Lung Cancer (CRC and NSCLC). However, how the microbial components of tissues and feces reflect each other remains unknown. In this work, our main objective is to know the degree of correlation between the composition of the tissue microbiota and that of the feces of patients affected by CRC and NSCLC. Specifically, we investigated tumor and non-tumor tissues from 38 recruited patients with CRC and 19 with NSCLC. DNA from samples was submitted for 16S rDNA metagenomic sequencing, followed by data analysis through the QIIME2 pipeline and further statistical processing with STATA IC16. Tumor and non-tumor tissue selected genera were highly correlated in both CRC and NSCLC (100% and 81.25%). Following, we established tissue-feces correlations, using selected genera from a LEfSe analysis previously published. In CRC, we found a strong correlation between the taxa detected in feces and those from colorectal tissues. However, our data do not demonstrate this correlation in NSCLC. In conclusion, our data demonstrate that the microbiota components of tumor and non-tumor tissues are similar, with only minor differences being detected. Furthermore, our results clearly demonstrate that the fecal microbiota reflects the microbial composition of intestinal tissue but not that of lung tissue.

Introduction: Evaluating the quality of patient care is a key indicator of the effectiveness of a health system. In the context of tuberculosis, such an evaluation appears necessary and timely in one of the specialized centers for tuberculosis patient care to assess its impact on achieving the targets of a health program, such as the tuberculosis control program. Objective: To assess the quality of care provided to tuberculosis patients at the Anti-Tuberculosis Center in Brazzaville. Method: A de-scriptive study conducted over six months using a questionnaire administered to tuberculosis pa-tients receiving follow-up during the study period. Results: A total of 139 tuberculosis patients were interviewed, including 75 women (54%) and 64 men (46%). The mean age was 36.7 ± 16.82 years (range: 17–76 years). Most patients were married (56.1%), lived in Brazzaville (95%), and had a secondary education level (49%). The reception was poorly rated in 72% of cases at the administrative level and 65% at the care level, including the lack of respect for privacy (99%). Patients were informed about their disease (87%), and the information provided was clear (73%). However, the reception quality was rated as poor (83%), although administrative procedures were easy. The waiting time for consultations and care was relatively long in 73% and moderately long in 84% of cases, respectively. The waiting conditions were deemed very poor in 90% of cases, and cleanliness was insufficient in 85%. The consultation duration was considered adequate in 90% of cases. The level of patient sat-isfaction was rated as insufficient in 48.2% of cases. Therapeutic success was achieved in 88% of cases, while 7% of patients were lost to follow-up, and 4% died. Conclusion: The quality of care for tu-berculosis patients at the Anti-Tuberculosis Center in Brazzaville should be improved by prioritizing patient-centered care.
