Estudo comparativo de ativação dos grãos de kefir sob temperatura ambiente para a produção de leite fermentado
Authors: Magalhães Raquel Da Silva , Palma Elaine Cristina Tridente , Procópio Raquel Da Silva , Racowski Ilana
Published: May 2024

Os grãos de kefir são compostos por uma matriz de polissacarídeos natural possuem uma microflora mista, composta por leveduras e bactérias. O produto proveniente da fermentação promovida pelos grãos do kefir em leite é o leite fermentado. Por se tratar de um produto difundido de forma artesanal há lacunas na literatura em relação a melhor forma de armazenamento, sobre as repicagens dos grãos pré-existentes e se os mesmos conseguem manter seu potencial probiótico. Pensando nisso foi avaliado o processo de ativação e da não ativação dos grãos após a repicagem quando armazenados em temperatura ambiente. Os grãos foram separados em dois grupos, GKA (ativados) e GKNA (não ativados), onde foram avaliadas as suas atividades metabólicas e a enumeração de bactérias láticas e leveduras, durante 28 dias. Os grãos ativados apresentaram vantagens em relação ao maior aumento de massa (25% para os GKA e 15% para os GKNA), os valores de pH e °Brix foram ligeiramente menores do que os apresentados pelas amostras GKNA. Por outro lado, a amostra GKNA apresentou valores de microrganismos maiores do que a amostra GKA. Concluindo, a ativação dos grãos não se apresentou vantajoso por ser um processo trabalhoso e não surtir efeito na multiplicação dos microrganismos.

INTRODUCTION:

Constipation is an independent risk factor for poor bowel preparation. This study aimed to evaluate the bowel cleansing efficacy and safety of polyethylene glycol (PEG) combined with linaclotide (lin) for colonoscopy in patients with chronic constipation (CC).

METHODS:

This single-blinded, randomized, controlled, and multicenter study was conducted from July 2021 to December 2022 at 7 hospitals. Patients with CC who underwent colonoscopies were enrolled and randomly assigned to 4 groups with split-PEG regimens: 4L-PEG group, 4L-PEG+1d-Lin group, 3L-PEG+1d-Lin group, and 3L-PEG+3d-Lin group. The primary outcome was rates of adequate bowel preparation, defined as a total BBPS score ≥6 and a score ≥2 for each segment. Secondary outcomes were adverse effects, sleep quality, willingness to repeat the colonoscopy, adenoma detection rate, and polyp detection rate.

RESULTS:

Five hundred two patients were enrolled. The rates of adequate bowel preparation (80.0% vs 60.3%, P < 0.001; 84.4% vs 60.3%, P < 0.001) and the total Boston Bowel Preparation Scale (BBPS) scores (6.90 ± 1.28 vs 6.00 ± 1.61, P < 0.001; 7.03 ± 1.24 vs 6.00 ± 1.61, P < 0.01) in the 4L-PEG+1d-Lin group and the 3L-PEG+3d-Lin group were superior to that in the 4L-PEG group. Compared with the 4L-PEG group, the 4L-PEG+1d-Lin group (66.7% vs 81.7%, P = 0.008) and the 3L-PEG+3d-Lin group (75.0% vs 81.7%, P = 0.224) had a lower percentage of mild adverse events. No statistically significant difference in willingness to repeat the colonoscopy, sleep quality, polyp detection rate, or adenoma detection rate was observed among groups.

DISCUSSION:

PEG combined with linaclotide might be an effective method for bowel preparation before colonoscopy in patients with CC.
HLA Genotyping in Children With Celiac Disease Allows to Establish the Risk of Developing Type 1 Diabetes

Published: May 2024

INTRODUCTION:

Celiac disease (CD) and type 1 diabetes (T1D) often co-occur and share genetic components in the human leukocyte antigen (HLA) class II region. We aimed to study the usefulness of HLA genotyping in predicting the risk of developing T1D in patients with CD and the temporal relationship between these diseases.

METHODS:

A cohort of 1,886 Sardinian patients, including 822 with CD, 1,064 with T1D, and 627 controls, underwent HLA class II typing. Seventy-six of 822 patients with CD were also affected by T1D (CD-T1D), and their HLA genotypes were analyzed for specific HLA associations with CD, T1D, and controls.

RESULTS:

High-risk HLA-DQ genotypes, including HLA-DQ2.5/DQ8, -DQ2.5/DQ2.5, and -DQ2.5/DQ2.3, were strongly associated with CD-T1D with frequencies of 34.5%, 15.9%, and 18.8%, respectively. Conversely, certain HLA genotypes associated with CD seemed to confer protection against T1D development. Therefore, HLA genotyping allows for the identification of those patients with CD who might develop T1D. The frequency of patients with CD preceding T1D is higher in younger children than older ones, with implications for the early childhood approach to diabetes prevention.

DISCUSSION:

CD is a condition for future T1D development, and specific HLA genotypes can predict this risk. Early screening for celiac autoimmunity and subsequent HLA typing in CD children could help identify those at high risk of T1D, allowing for proactive interventions and immunotherapies to preserve β-cell function. These findings may support the re-evaluation of HLA typing in children with CD.
Model-Free Sliding Mode Control for a Nonlinear Teleoperation System with Actuator Dynamics
Authors: Abdelwaheb Henni Mansour , Abderrahmane Kacimi , AEK Belaidi
Published: May 2024

Teleoperation robotic systems control, which enables humans to perform activities in remote situations, has become an extremely challenging field in recent decades. In this paper, a Model Free Proportional-Derivative Sliding Mode Controller (MFPDSMC) is devoted to the synchronization problem of teleoperation systems subject to actuator dynamics, time-varying delay, model uncertainty, and input interaction forces. For the first time, the teleoperation model used in this study combines actuator dynamics and manipulator models into a single equation, which improves model accuracy and brings it closer to the actual system than in prior studies. Further, the proposed control approach, called Free, involves the simple measurement of inputs and outputs to enhance the system's performance without relying on any knowledge from the mathematical model. In addition, our strategy includes a Sliding Mode term with the MFPD term to increase system stability and attain excellent performance against external disturbances. Finally, using the Lyapunov function under specified conditions, asymptotic stability is established, and simulation results are compared and provided to demonstrate the efficacy of the proposed strategy.
Escritores y artistas ante la política: debates intelectuales y prácticas estéticas en la cultura de izquierdas en Argentina (1920‒1970). Presentación
Authors: Alle María Fernanda , Devés Magalí A. , Prado Acosta Laura
Published: May 2024

Este dossier ofrece un panorama de algunas indagaciones actuales que se están llevando adelante en torno a los cruces entre el arte, en sus múltiples expresiones, y la política, que se suscitaron en la cultura de izquierdas en Argentina, entre 1920 y 1970. El objetivo central radica en relevar y discutir nuevas miradas y perspectivas críticas en torno a problemas, objetos, prácticas estéticas, debates y espacios de sociabilidad relacionados con la compleja vinculación entre arte y política en el país a lo largo del período recortado. Por medio de un eje compartido que recupera el transitado tópico acerca del compromiso de los/las intelectuales —y su contraparte, el de la autonomía de las prácticas artísticas—, que adquirió importantes resonancias en ciertas coyunturas de radicalización política a nivel internacional, los artículos indagan diferentes posicionamientos, actos creativos y modos de intervención a los que apelaron escritores/as, periodistas, músicos/as y artistas visuales ante dichas coyunturas, que eluden cualquier definición rígida o dogmática acerca de lo que debería establecer tal compromiso. En todos los casos, se trata de debates y prácticas en las que está en juego una valoración del arte concebido como instrumento capaz de aportar a una lucha política figurada en términos de una transformación que incluía una batalla cultural.
Experiencias locales de un antifascismo internacional. Escritores de América en defensa de la democracia
Authors: Merayo Sebastián Nicolás
Published: May 2024

En este artículo proponemos narrar un acontecimiento político‒cultural relacionado a la trama de solidaridad internacional en torno al exilio español republicano una vez finalizada la Guerra Civil en aquel país. Para ello nos referiremos a una intervención desarrollada en la ciudad de Rosario en abril de 1939, cuya finalidad fue la de recaudar fondos para el traslado de españoles hacia Chile en el vapor Winnipeg. La principal figura e impulsor de esta travesía fue el escritor y embajador cultural de Chile en Francia, Pablo Neruda. Con su presencia, sumada a la de otras figuras de la cultura, tanto locales como internacionales, se llevó a cabo un acto bajo el título «Por la defensa de las democracias en América» en el Teatro Cine Real de esta ciudad. El evento dejó trascender algunos aspectos que nos interesan explorar. Por un lado, el impacto local de las prácticas de solidaridad internacional asociada al antifascismo; por otro, la emergencia de espacios asociativos culturales conformados por intelectuales comprometidos ideológicamente; por último, planteamos una reconstrucción del panorama político cultural a partir de un cruce entre diversas fuentes hemerográficas como la prensa local, los diarios de las organizaciones, el Boletín de Cultura Intelectual y los prontuarios policiales en la descripción de dicho evento.
Quadros sartreanos: Un dios cotidiano, de David Viñas; Informação ao crucificado, de Carlos Heitor Cony
Authors: Schmitz Kremer Natan , Fernandez Vaz Alexandre
Published: May 2024

Que David Viñas, na Argentina, e Carlos Heitor Cony, no Brasil, são reconhecidos como precursores da recepção do existencialismo sartreano, não resta dúvida. Ao passo, contudo, em que Un dios cotidiano é comumente lembrado pela crítica, Informação ao crucificado é por ela esquecido. Nos romances, entretanto, são diversas as proximidades, como um espaço narrativo comum —o seminário—; uma desconfiança compartilhada sobre o Cristianismo; temas que se coadunam em imagens da violência. O texto busca, então, comparar as obras, mostrando o que guardam da recepção do existencialismo na América, ao mesmo tempo em que aponta tanto aos limites do movimento francês quanto às possibilidades de ruptura em sua recepção na Argentina e no Brasil.
Carlos Alberto Brocato: otros años 60 (y setenta)
Authors: Manduca Ramiro
Published: May 2024

Las dinámicas del campo intelectual argentino entre los años 60 y 70 han sido un objeto de estudio visitado asiduamente en las últimas décadas. En su gran mayoría las investigaciones al respecto han puesto énfasis en los cambios producidos durante esos años al calor de la «radicalización política», limitando, en muchos casos, su alcance a la adhesión de una fracción del campo intelectual a la lucha armada. El canónico trabajo de Oscar Terán al respecto sin dudas ha proporcionado una de las principales claves de lectura en ese sentido. En este caso reconstruiré la trayectoria de Carlos Alberto Brocato, quien transitó esos años a contracorriente de sus compañeros de pluma. Recorreré sus principales aportes y debates desde su expulsión del Partido Comunista y su rol como director de la revista La Rosa Blindada en 1964 hasta su ruptura con el Partido Socialista de los Trabajadores (PST) de orientación trotskista, visitando antes los aportes realizados en esta organización en pos de la organización de los intelectuales y artistas. A lo largo de esos tres momentos nos interesa ver el modo en que fue madurando la concepción de «intelectual militante» con la que el escritor definía su praxis.
risa y el juego como irreverencias poético‒políticas en Roberto Santoro
Authors: Catalano Agustina
Published: May 2024

La hipótesis principal de este trabajo sostiene que lo político en la escritura de Roberto Santoro se redefine y actualiza mediante el juego y la risa como dispositivos desde los cuales leer e interpretar la violencia dictatorial y las militancias de izquierda. Lejos de la denuncia o la protesta a secas, su poesía transgrede los lugares comunes o las formas cristalizadas de acercarse a la realidad histórico‒política de los años 70, a través del humor negro, la ironía y la reescritura de juegos infantiles, rondas y canciones populares. Se tendrán en cuenta para el análisis sus últimas dos publicaciones en vida —Poesía en general (1973) y No negociable (1975)— y poemas que permanecieron inéditos hasta la aparición de su Obra poética completa (2009). Allí se puede advertir un procesamiento del contexto represivo y sus efectos sobre los cuerpos y las subjetividades que no niega el dolor o la bronca, tampoco el entusiasmo militante, pero sí incorpora nuevos tonos y figuras a la imaginación revolucionaria, como el chiste, el calambur, el baile o los rituales infantiles.

To copy verbatim, paraphrase or summarize – listeners’ methods of discourse representation while recalling academic lectures
Authors: Wang Haiping , Yu Guoxing
Published: May 2024

It is unanimously agreed that comprehension of academic lectures is cognitively demanding; however, few studies have focused on a listener’s real-time discourse representation of a lecture. Based on the qualitative analysis of the verbal protocols, the present study investigated sixteen Chinese university students’ verbal recall of an academic mini-lecture to explore how they made sense of the lecture and represented its discourse when they recalled it episode by episode, and to what extent they differed in discourse representation. The results show that listeners’ discourse representation involved a range of cognitive processes such as paraphrasing, summarizing, and verbatim copying. Paraphrasing and summarizing were the main methods of discourse representation used by the participants when they verbally recalled the lecture. Those who correctly paraphrased more idea units recalled more content of the lecture. They were able to select and retain more idea units in their short-term memory, build more associations between the selected idea units, integrate them with the existing discourse structures and ensure contextual coherence in the construction of the local discourse structures. The findings of the study contribute to a better understanding of how listeners comprehend academic lectures and confirm that improving students’ paraphrasing skills and hierarchical discourse construction in recall are conducive to better comprehension of academic lectures.
Point-of-care testing, near-patient testing and patient self-testing: warning points
Authors: Banfi Giuseppe , Božič Borut , Cihan Murat , Pašalić Daria , Pennestrì Federico , Plebani Mario
Published: May 2024

Point-of-care testing (POCT), near-patient testing (NPT) and patient self-tests (PST) are diagnostic examinations performed at the time and place of patient care. While POCT and NPT are performed and analyzed by medical professionals, PST are based on samples and parameters directly collected and analyzed by lay users. These tests are spreading both in high income countries and in low to middle income countries as they are expected to improve healthcare efficiency and equity, by saving resources, releasing pressure from hospitals and reducing logistical barriers. However, accurate multidisciplinary assessment is mandatory to ensure that what they promise is real. We reviewed some important ethical aspects, international standards and regulations. The current risks associated with alternative ways of testing are explained by the principles of respect for patient autonomy and non-maleficence. Further evidence from multidisciplinary assessment is needed to evaluate pros and cons in light of the principles of beneficence and justice. Although POCT or NPT need common regulation and accurate provider training to ensure safe and appropriate interpretation of results, PST needs even more attention as they are subject to direct patient use. Randomized controlled trails including patient education should be conducted in order to provide reliable evidence on clinical outcomes, patient acceptance and cost-effectiveness. Mandatory regulation is needed to avoid harm and EU regulation should help different countries maintain a safe use of devices in a global population of producers and users.

Authors: Saha Debasree , Mukhopadhyay Chhanda
Published: May 2024

Imidazoles have a unique position in heterocyclic chemistry as these constitute the basic framework of several bio-molecules. Thus, increasing research is being carried out on the synthesis of imidazoles and their derivatives, mainly because of the application of imidazoles in pharmaceutical and medicinal research. Keeping sustainability in mind, researchers are developing synthetic pathways for the synthesis of imidazoles and their derivatives by employing techniques involving green tools, thus leading to sustainable pathways. In this review, we aim to compile such synthetic methodologies involving green tools for the synthesis of imidazoles. The review will cover the synthetic reactions that involve green tools such as microwave irradiation, ultrasound irradiation, and ball milling. We aim to highlight the scope and relevance of such green tools in today’s synthetic research. Through this review, we wish to contribute towards the synthesis of imidazoles that serve as a useful class of heterocyclic compounds involved in the development of pharmaceutically active molecules. We sincerely hope that this review will serve as a relevant guide for future sustainable research in the synthesis of imidazoles and their derivatives.

Five needs of teenage pregnant women are factors that can support mental health to prevent depression during pregnancy.
Female-to-male (FtM) transgender individuals’ multimodal and interactional practices in Japanese
Authors: Fukuda Chie
Published: May 2024

This study explores the multimodal and interactional practices of female-to-male (FtM) transgender individuals in Japanese, focusing on their identity construction. Most previous studies on transgender identity in Japanese contexts examine male-to-female (MtF) transgender individuals’ linguistic practices, particularly the use of so-called Japanese women’s language. In contrast, this study explores how FtM individuals use not only linguistic but also other semiotic resources to construct and negotiate their gender and sexual identities. The study utilizes empirical data such as YouTube videos and draws on multimodal conversation analysis (CA) and membership categorization analysis (MCA) to analyze the participants’ accomplishment of social actions. The findings demonstrate the use of various resources for identity construction and how the participants challenge and/or conform to hegemonic gender ideologies. The study also unveils both the diversity among FtM transgender people (inter-individual variation) and the fluidity and complexity of identities that can exist within one person (intra-individual variation).

Published: May 2024

Pathogen infection can damage agricultural products, thereby reducing their economic value. Fusarium spp. is a fungal pathogen that infects potatoes (Solanum tuberosum L.) and causes dry rot. In this study, we utilized visible–near-infrared (Vis–NIR) and shortwave–near-infrared (SW–NIR) spectroscopy for the early detection of Fusarium spp. infection in potato tubers. The spectrometer used in this study analyzed the Vis–NIR (400–1,000 nm) and SW–NIR (970–1,700 nm) regions. A total of 183 potato (G2 “Granola L.” variety) samples were used. Among these, 93 samples were artificially inoculated with Fusarium solani mycelia, while 90 samples were left uninfected and considered the control group. The potato samples were stored at two different temperatures (12 and 25°C). Vis–NIR and SW–NIR spectra were analyzed by a chemometric method, namely principal component analysis with linear discriminant analysis (PCA–LDA), to differentiate healthy and infected potatoes. The PCA–LDA model based on Vis–NIR spectra exhibited a calibration accuracy of 80.26% and a reliability of 65%. Meanwhile, the PCA–LDA model based on SW–NIR spectra exhibited a calibration accuracy of 100% and a reliability of 97.30%. Overall, both methods demonstrated their suitability for differentiating potato tubers with Fusarium spp. fungal infection and healthy ones; however, the results suggest that SW–NIR spectroscopy is more effective than Vis–NIR spectroscopy.

Published: May 2024

Casson fluids containing carbon nanotubes of various lengths and radii on a moving permeable plate reduce friction and improve equipment efficiency. They improve plate flow dynamics to improve heat transfer, particularly in electronic cooling and heat exchangers. The core objective of this study is to investigate the heat transmission mechanism and identify the prerequisites for achieving high cooling speeds within a two-dimensional, stable, axisymmetric boundary layer. This study considers a sodium alginate-based nanofluid containing single/multi-wall carbon nanotubes (SWCNTs/MWCNTs) and Casson nanofluid flow on a permeable moving plate with varying length, radius, and nonlinear thermal radiation effects. The plate has the capacity to move either parallel to or perpendicular to the free stream. The governing partial differential equations for the boundary layer, which are interconnected, are transformed into standard differential equations. These equations are then numerically solved using the Runge–Kutta fourth-order scheme incorporated in the shooting method. This research analyses and graphically displays the effects of factors including mass suction, nanoparticle volume fraction, Casson parameter, thermal radiation, and temperature ratio. Additionally, a comparison is made between the present result and the previous finding, which presented in a tabular format. The coefficient of skin friction decreases in correlation with an increase in Casson fluid parameters and Prandtl number. Heat transfer rate decreases with a variation in viscosity parameter, while it is increasing with an increase in Prandtl number. In addition, this study demonstrates that heat transfer rate for MWCNT is significantly higher than that of SWCNT nanoparticles. Thermal radiation and temperature ratio reduce the heat transfer rate, whereas nanoparticle volume fraction and Casson parameter enhance it over a shrinking surface.
Consumer Behaviour on AI Applications for Services: Measuring the Impact of Value-Based Adoption Model on Luxurious AI Resorts’ Applications
Authors: Skandali Dimitra , Magoutas Anastasios , Tsourvakas Georgios
Published: May 2024

Focussing on consumer behaviour analysis derived from the changes in Information and Communications Technology (ICT), the purpose of this study is to analyse the primary content factors that influence consumers’ attitudes and behavioural intentions in the hospitality industry. The present study is the first to investigate how benefits (happiness and perceived immersion) and sacrifices (trust and changes in habits) can predict consumers’ attitudes of acceptance and willingness to pay for artificially intelligent (AI) luxurious resort applications (apps). The researchers employed structural equation modelling to analyse the relationship between technology adoption and specific factors that influence customers’ perceived value in the hospitality industry. The research aims to expand on the theory of the Value Adoption Model (VAM). Based on the findings, AI-powered apps for high-end resorts have a tendency to boost tourists’ confidence and willingness to use and pay for these apps, as well as increase their perceived value. Happiness has an impact on behavioural intentions, while perceived immersion and changes in habits influence the outcomes related to intentions to ultimately accept and purchase them. The findings can benefit both ICT and the hospitality industry. Managers in the ICT industry should collaborate with researchers in service management who are exploring the challenges of technology adoption. Managerial implications and recommendations for future research are extensively provided.
Principales rasgos gramaticales del español de Costa Rica
Authors: Pato Enrique
Published: May 2024

This work offers an in-depth description of the main morphosyntactic (and lexical) features found in present Costa Rican Spanish, a lesser-known Central American variety. Text corpora and sociolinguistic surveys help us to provide an updated grammatical overview, which takes into account most categories: nouns and adjectives, pronouns, verbs, adverbs, prepositions and idioms, and is illustrated by examples taken both from formal and informal settings. By comparing these features with previous grammatical descriptions, this study helps in identifying some common American features – such as the use of hasta and una mi amiga – as well as some specific patterns – such as the prominence of several suffixes and parasynthetic verbs, as well as some adverbs – in present-day Costa Rican Spanish, some of which remain to be incorporated in the Academy grammar.
Une ancienne dénomination du puits absorbant figée dans la microtoponymie de la Haute-Saône : les Anduits (Lavigney, Malvillers et Melin)
Authors: Chambon Jean-Pierre , Groscolas René
Published: May 2024

Les Anduits, the name of a territory comprising parts of three Haute-Saône villages (Lavigney, Malvillers, and Melin), is the sole example of its type in French toponymy. Examination of the area leads us to postulate an Old Franc-Comtois (or Regional Middle French) *enduit ‘dry well’, nominalisation of the past participle of Old and Middle French enduire ‘seep in the ground (of water)’. This formation is parallel to the suffixal derivative ˹enduisoir˺ ‘dry well’, which is formed from the present participle stem of the same verb and is abundantly attested in the northern part of Franche-Comté (lexicon and microtoponymy).

Due diligence of transnational companies in India
Authors: de Hurtado Sadcidi Zerpa , Hurtado Briceño Alberto José
Published: May 2024

Due diligence is the minimum framework for responsibility and reparation for damages in matters of human rights that may arise during and after the production processes of companies have been carried out. In other words, an alternate strategy for encouraging businesses to voluntarily engage with the externalities that their operations may create. This paper aims to evaluate the notion of due diligence in international corporations situated in India using a qualitative case study technique. In this regard, due diligence and its guiding principles are defined to assess the transparency and management responsibility of international companies in India. Then, cases related to positive and negative aspects of due diligence in this Asian country are presented. Finally, conclusions are given. The results lead to the conclusion that even though India is a desirable destination for international investments in industries like electronics, fashion, IT, finance, and the automotive sector, foreign firms have not yet demonstrated that they have complied with due diligence requirements. The most vulnerable population continues to be subjected to cycles of poverty, slavery, and mistreatment because some of the jobs paid by large corporations represent the only means of economic subsistence.
Philosophical analysis of ethnicity in modern African politics, leadership and governance
Authors: Lajul Wilfred
Published: May 2024

Philosophical analysis of ethnicity in modern African politics leadership and governance argues that the millionist touted idea that nationalism and ethnicity would dissipate as globalization and of course universalization of political ideas on governance unfolded have been disproved as both nationalism and ethnicity have on the contrary resurged and proliferated. This points out that although there are several conceptualizations of ethnicity; the one being singled out for closer study and analysis is instrumental ethnicity, the kind strategically fermented by the political elites who at times double as military leaders, ostensibly for ethnic benefit but more often than not, for the exclusive benefits of the political or military elites themselves. The nuanced dialectic at play with instrumental ethnicity is that, superficially it looks like everybody in the ethnic grouping will benefit; indeed, for some time they may as ethnic members feel it is their son/daughter in charge, a kind of psychological satisfaction, which may be accompanied by some rudimentary economic benefits. Closer study of the dynamics of sharing locally generated resources and revenue, however, shows that lack of transparency and equity in the apportionment of those resources ends up fanning civil/tribal unrest and may flair out into open conflicts.
Nonalcoholic fatty liver disease: a review of physiology, treatments, and market outlook
Authors: Aryan Pammar
Published: May 2024

The liver is a multifunctional organ with a wide variety of roles in the body; it is highly vascularized, and 25% of cardiac output is directed toward the liver. Non-alcoholic fatty liver disease (NAFLD is diagnosed when liver cells are injured as a result of fat buildup. People with NAFLD are at greater risk of having the disease progress to hepatis, cirrhosis, and liver cancer. The purpose of this review is to discuss the physiology, available treatments, and market for non-alcoholic fatty liver disease (NAFLD). NAFLD has increased in frequency around the world in the last 20 years, and this trend is predicted to continue into the future. The best known treatment for NAFLD is liver transplantation, but only a fifth of the patients who need treatment are provided with a donor liver. One alternative to a liver transplantation is the use of an artificial liver support system, which uses a variety of dialytic techniques to treat the blood plasma outside the body. Researchers are currently in the process of building bioartificial livers and chemically derived drugs to help reduce the effects of NAFLD, which can range from liver cancer to cirrhosis. While the list of treatments for NAFLD is limited, there is great potential for the industry to grow exponentially once additional treatments are approved by the Food and Drug Administration (FDA).

Transplantation of mesenchymal stromal cells (MSCs) is a promising direction in the therapy of ischemic stroke, which promotes the regeneration of neurons in experimental and clinical studies. We evaluated the neuroprotective and angioprotective properties of intravenously transplanted allogeneic and xenogeneic MSCs obtained from human and rat adipose tissue, human umbilical cord Wharton jelly and its cells lysate compared with citicoline in a rat brain ischemia-reperfusion model. We studied the somatosensory cortex and CA1 zone of the hippocampus in rats using immunohistochemical analysis. It was found that the CA1 zone of the hippocampus was the most sensitive to ischemic damage. Analysis of brain sections 7 and 14 days after ischemia-reperfusion showed that all treatment options increased the staining intensity of NeuN-positive neurons, but did not reach the control value in sham-operated rats. To quantify the obtained results, we used the integrated fluorescence density indicator, which demonstrated a decrease in the fluorescence intensity of NeuN-positive neurons in 4.2 (7 days) and 3.2 times (14 days). All treatment variants significantly increased the intensity of fluorescence, but human umbilical cord Wharton’s jelly MSCs gave the best result. There was no difference in the fluorescence intensity of RECA-1-positive blood vessels. Thus, immunohistochemical analysis using a broad panel of antibodies against neurons and endothelial cells demonstrated that ischemia-reperfusion resulted in the death of NeuN-positive neurons in the CA1 zone of the hippocampus. Transplantation of stem cells of different origin, lysate of umbilical cord Wharton’s jelly MSCs and administration of citicoline had a neuroprotective effect on the CA1 zone of the hippocampus. However, the best result has been shown by the treatment with Wharton’s jelly MSCs.
Degenerative disc disease: analysis of treatments, tissue, and market
Authors: Bill Tawil , Tamura Kelly
Published: May 2024

The prevalence of intervertebral thinning discs and the degradation of spinal discs as a whole has created a new market and area of research to find a solution to this age-related problem. The loss of the cartilage cushioning two vertebrae is called degenerative disc disease, or DDD. DDD can impact a patient’s quality of life greatly – putting them in severe pain, limiting mobility, and decreasing their ability to perform daily activities. The market for DDD treatment shows promising growth, both globally and in the US. Most of the drugs and devices that are currently on the market aim to alleviate pain or reduce inflammation, addressing the symptoms of DDD rather than regenerating the lost disc tissue. However, there are many new treatments that are in development or are being tested in clinical trials that could satisfy this need. In the context of tissue engineering, regeneration of the intervertebral disc is a prime target. A scaffold could fulfill the need for mechanical support in between the vertebrae and growth factors and cells could stimulate the regrowth of the injured tissue.
Global facial rejuvenation with hyaluronic acid: a safe set of directives to whole-approach of the aging-changes evaluated by magnetic resonance imaging
Authors: AC Abramo , Arnon Bastos Paulo
Published: May 2024

Background: Face rejuvenation with hyaluronic acid (FR-HA) through a global approach was performed in a single session, by using a safe set of directives targeted for each facial zone. Methods: FR-HA was performed with products of the QTFill Signature® range all of them with same HA-concentration and molecular-weight, with two crosslinking technologies, the own Ultra-High-Density™ crosslinking and BDDE-crosslinking with tree degrees of BDDE, resulting in high-, medium- and low-G', and 3.0% of lidocaine hydrochloride. Bolus injection with needle and retrograde-backflow injection with microcannula or needle were directed to specific facial zones. A safe FR-HA protocol based on HA-products, fat layers and vasculature, and points and techniques of injection recovered the face youthful appearance. Results: FR-HA was made for eleven facial zones, patient average of 6.95±1.30, average of 30.55±0.74 injections-points per facial-zone and of 16.80±0.83 injections-points per patient. The volume of HA injected was 49.50 ml, average of 4.50±0.37 ml per facial zone and 2.48±0.12 ml per patient. From one-month to twelve-months there was no significant differences on the face appearance and on density of the gel-diffusion displayed by MRI in T2-weighted with fat suppression on axial and coronal planes, which were endorsed by the Facelift Outcomes Evaluation questionnaire scores. Conclusions: Minimal changes on clinical outcomes and slow degradation of gel-diffusion on MRI in T2-weighted with fat suppression on axial and coronal planes from one-month to twelve-months showed that the HA-products remained stable in the injection site without evidence of significant resorption or loss of correction, indicating FR-HA efficacy and long-lasting.

Having apparel similar to what others are wearing is a basic desire in the fashion world and results in copying. Copying is both easier with technology and more prevalent with the attraction of brands and logos; however, research in the fashion literature is limited in the exploration of copying. To address this gap, this study investigated the definition of copying, the integration of copying technologies into product development, and training within the industry relative to copying and counterfeiting. Ten product development personnel working in the fashion industry were interviewed using an online, structured survey technique. Findings indicate that copying is inherent in the product development process for fashion goods with important implications for education and training about copying and counterfeiting.
Traumatic pulmonary pseudocyst a case report: surgery? Follow-up?
Authors: Agar Mehmet , Kalkan Muhammed , Gulcek Ilham
Published: May 2024

Traumatic pulmonary pseudocysts represent uncommon parenchymal sequelae ensuing from thoracic trauma, typically arising subsequent to blunt force trauma. Generally benign in nature, these lesions frequently resolve spontaneously without necessitating specific therapeutic interventions. The significance of these acute cystic formations lies in the potential for misinterpretation by clinicians unfamiliar with their characteristics, leading to erroneous diagnoses such as malignancies or benign lung lesions. In this case report, we wanted to show that traumatic pulmonary pseudocysts, even if large in size, can resolve with follow-up without the need for surgery.

The article is dedicated to determining the energy indicators of a generating complex with stochastic wave energy gen-eration. The aim of the study is to compare the energy indicators and power consumption coefficient of wave energy generating complexes' simulation models with magneto-electric generators operating at variable speeds under resistive and resistive-capacitive loads with rectified voltage. The analytical method is employed to calculate the parameters and energy indicators of the magneto-electric generator. The calculation includes inductance, resistance, and voltage gen-erated by the rotor with permanent magnets in the three-phase winding of the magneto-electric generator for electrical circuit modeling with and without a three-phase current rectifier, as well as active-reactive and active loading. The rotor rotation frequency varies harmonically with the same period and amplitude for all electrical circuits. The deter-mined current in the electrical circuits is used to calculate the generator's electromagnetic field and energy indicators. Comparisons are made for circuits with active and active-reactive loads, including power consumption, power losses in the stator winding, power output from the generator, and the power consumption coefficient of wave energy. The com-parison of energy indicators is conducted under the condition of equal rotor oscillation frequency and shaft torque, achieved by varying the load resistance. Bibl. 10, fig. 8, table.

The paper presents the results of studying the effect of wire sagging on the charging capacity of an overhead power line. A refined mathematical model of the overhead line charging capacity is obtained. The results of the study of the error of neglect of wire sagging for typical structures of overhead power lines with voltage from 35 to 750 kV with the arrangement of wires in 2-3 tiers and horizontal arrangement are presented. The influence of changes in the wire sagging boom on the value of the power line charging capacity due to changes in the operating temperature of the wire and due to ice deposits is investigated. It is shown that for 750 kV power lines, such a change can reach 1-1.5%, which, in combination with the long length of the main power lines, can cause a change in the balance of reactive power in the line itself and in adjacent power systems. The possibility of monitoring the wire sagging boom in a run is investigated and the requirements for the accuracy of such measurements are determined. Bibl. 14, fig. 3, table.
