Published: April 2024

The research was conducted with the aim of establishing a connection between plasma amino acid peculiarities and Holter ECG monitoring indexes in Coronary Artery Disease (CAD) and Atrial Fibrillation (AF) patients. 300 patients were examined divided into 3 groups: I – 149 patients with CAD without arrhythmias, II – 124 patients with CAD and AF paroxysm, and the Control Group (CG) – 27 patients without CAD and arrhythmias. Holter ECG monitoring was performed for the patients with AF within 24 hours after sinus rhythm restoration, and for the patients without AF on the first day of observation. Plasma AA level was detected by the method of ion exchange liquid column chromatography. It was established that there is a significant increase glutamate and Branched-Chain Amino Acids (BCAA) levels in patients of the II group, and significant depletion in glycine levels comparison with the I group patients (p<0.05). In the II group patients, an increase in SupraVentricular (SVE) and Ventricular Extrasystoles (VE) was checked in comparison with the I group patients (p<0.05). Total SVE was significantly correlated with threonine (r=-0.316), serine (r=-0.336), glycine (r=-0.397), isoleucine (r=0.317), BCAA (r=0.356), and glycine+serine sum (r=-0.302), p<0.05. AF paroxysm was significantly correlated with taurine (r=-0.302), serine (r=-0.328), glycine (r=-0.311), glutamine (r=-0.304), and glycine+serine sum (r=-0.379), p<0.05. Total VE was significantly correlated with glycine (r=-0.370) and tyrosine (r=0.325), p<0.05. Changes in ST-segment were significantly correlated with tyrosine (r=0.307), phenylalanine (r=0.318), and Aromatic Amino Acids (AAA) (r=0.379), p<0.05. We concluded that glycine, serine, and BCAA are significantly correlated with cardiac arrhythmias. Changes in ST segment are significantly correlated with AAA levels.

Authors: Gödekmerdan Elif , Kocar Günnur
Published: April 2024

This work explores the effects of the temperature (250, 280, 310°C), time (20, 40, 60 min), sewage sludge mixing ratio (25, 50, 75%) on the solid fuel quality and yield of the biochar produced from sewage sludge blended with pine sawdust. The optimal conditions for the torrefaction of sewage sludge and pine sawdust were investigated by the response surface methodology. Mathematical models were developed on the weight yield, high heating value and ash content and experimental data were examined through analysis of variance. The results depicted that the effects of temperature and mixing ratio were more considerable than residence time for the three response variables. The optimum point for weight yield, HHV, ash were predicted to be 60.82%, 21.58 MJ kg-1 and 18.78% at 310°C, 20 min and sewage sludge mixing ratio of 25%, respectively. The experimental results show that the average values of the experiments were 56.4%, 22.9 MJ kg-1, and 21% for weight yield, HHV and ash content, respectively.

Published: April 2024

The modern standard in dentistry is minimally invasive treatment, as it allows you to preserve the viability of teeth.
The purpose of this study was to evaluate the possibility of using an autofluorescence diagnostic device (AFS) to determine the end-points of the carious cavity preparation.
Material and methods. The study was conducted on ten third molars extracted for medical reasons. Autofluorescence with AFS device and caries-marker were used to visualize infected carious dentin at different stages of cavity preparation.
Results. The method showed effectiveness for differentiating affected and infected dentin. Sound dentin, dense carious dentin, and soft infected dentin was characterized with green, orange, and red fluorescence, respectively. The data obtained from caries markers do not always coincide with the probing indicators and the AFS device. For the FACE method with AFS device sensitivity, specifity, and overall diagnostic accuracy were 81.8%, 88.9%, and 85%, respectively. For the caries-marker sensitivity, specifity, and overall diagnostic accuracy were 90%, 77.8%, and 80%, respectively.
Conclusions. The AFS device allows selective removal of infected dentin more carefully compared to caries-marker staining as fluorescence allows us to visualize infected dentin and to preserve demineralized (affected) dentin.
Contrapontos religiosos em Clarissa, de Erico Verissimo
Authors: Oliva Osmar Pereira
Published: April 2024

O romance Clarissa, de Erico Verissimo, publicado inicialmente em 1933, apresenta ao leitor uma galeria de tipos humanos que representam diversas identidades, concentradas em um só espaço, a pensão da tia Zina. Dentro desse microcosmo social brasileiro, no contexto histórico muito próximo da primeira guerra mundial, do crash da bolsa de valores de Nova York e da Era Vargas, o autor constrói personagens que poderiam ter existido nesse período, que poderiam ter sido seus conhecidos, como o judeu Levinsky e o protestante Gamaliel. Já nesse romance de iniciação, Verissimo investe na técnica do contraponto, recurso recorrente em toda a sua ficção, a fim de levar o seu leitor a uma dialética sobre questões históricas, econômicas, religiosas e afetivas. Este trabalho propõe, portanto, uma análise literária das representações do judeu e do protestante, articulada a essa contraposição.

A Phenomenological Analysis of the Effect of the Covid-19 Pandemic on School-Going Children
Authors: Joseph Asha , Zacharias Kakkamthottil Tobby
Published: April 2024

Objective: This paper looks at the COVID-19 pandemic that continues to affect humanity and school-going children in specific, in myriad ways even to this day , thr ough a phenomenological lens.
Background: The jury is still out on whether the Coronavirus SARS-COV -2 is man-made or a natural mutation. What has been established beyond doubt is that the disease has its origins in the city of Wuhan, in Hubei province in China, in December 2019. In the first wave, the disease seemed to affect senior citizens and those whose immunity was already compromised because of pre-existing conditions like diabetes, cardiovascular diseases and obesity . The second wave affected middle-aged with similar immunity-compr omised health profiles. While adolescents and children were relatively unaffected by the severity of the disease, their lives were definitely altered in irr evocable ways.
Methodology: The authors have synthesized what they themselves have observed and experienced along with those of various subject matter experts like doctors, epidemiologists, scientists and other researchers thr ough the articles in research journals as well as other media to understand how the pandemic has affected, continues to affect and may affect school going children in years to come.
Key Findings: It is clear that the pandemic, the consequent lock-downs as well as shifting to on-line learning for a good part of 2 years have robbed these children of two valuable years of growth and development both from an educational as well as from a social, psychological and emotional adaptability and maturity perspective. What is not yet clear is the health effects of the disease itself as well as the vaccination. On the positive side, school-going children seem to be more environmentally conscious and vocal about the need to leave the earth in a better state than what they have inherited.
Implications:As a society, will need to continue to provide whatever support we can to help limit the damage that the pandemic has inflicted on the psyches and personalities of these children and help the recover some of those lost years. We owe it to them.

Authors: Roy Raveena , K. S. Lakshmi
Published: April 2024

In the recent past, the concept of sustainability has gained immense significance due to the ongoing climatic changes and environmental degradation. It has thus become imperative that consumers consider measures towards ensuring the environment is protected, we consume just what is required and leave it for future generations to cherish. One of the measures to start is to shift towards sustainable products. The purpose of this paper is to study the factors influencing the purchase of sustainable products among Gen Y and Gen Z in Bengaluru City. This descriptive type of research employed a well-structured questionnaire and Simple random sampling method was used. The questionnaire was validated through Pilot study and reliability analysis. The primary data was collected from 250 respondents and the same was analysed using descriptive statistical tools and inferential analysis including exploratory factor analyses (EFA). Findings show that Gen Y and Gen Z were equally aware of sustainable products. Friedman test revealed that among various reasons, the purchase of products to serve the purpose had the highest mean rank while concern for the environment secured the lowest and thus, the purchase of sustainable products is driven by personal reasons rather than environmental reasons. The contribution of media to increase the awareness levels of sustainable products among Gen Y and Gen Z was significant, though the sources of media engagement were different. Thus, while marketers are advertising sustainable products, care should be taken to convey the environmental benefits of such products along with enhancing customer knowledge.

Published: April 2024

Here we aimed to enhance azimuth estimation to accurately locate a communication partner’s position by utilizing a low-resolution underwater acoustic lens system for communication. We proposed a method to accurately estimate the direction-of-arrival (DoA) by finding the center of gravity of the focal distribution using two adjacent elements of the transducer array. Ranging was to be based on time-of-flight (ToF). The method’s effectiveness was evaluated by two-dimensional finite difference time domain simulation. The lens’s focused sound field was calculated and the array was designed based on the result. DoA and ToF were estimated from the received signals and evaluated by comparing them with the true values under conditions involving 1-, 2-, and 3- users. The results confirmed DoA estimation with an error of almost 4°, even when using a lens system with an azimuth resolution of 10°. As the number of users increased, the maximum error value increased, though slightly.

Analysis of acceptance and use of the agree mart mobile groceries marketplace application using the UTAUT-3 Model in Indonesia
Authors: Salman Irfan Nurdin
Published: April 2024

The use of applications for trade transactions in the digital era is increasingly in demand by the public, one of which is to meet their daily needs. There is no exception in the food sector to meet the needs of kitchens and fresh products, more and more applications are trying to meet these needs. However, the commodities that are sold are commodities that are quite vulnerable both in terms of price (price sensitive) and resilience (perishable goods). Instead of creating e-commerce groceries in the food sector, PT Telkom Indonesia prefers to create a grocery marketplace, so that it is not affected by price conditions and product durability because the products sold are owned by MSMEs. On the other hand, Indonesian people are used to getting promos from applications when they are about to adopt an application or when they are about to make a transaction. This is a challenge for app creators to acquire consumers and maintain active user retention so that the business can continue.

Purpose: This research was made with the aim of being able to find out what things affect the community as consumers of fresh products and kitchen needs to adopt the Agree Mart groceries marketplace by implementing the UTAUT-3 model (Unified Theory of Acceptance & Use of Technology 3)

Research methodology: This research method uses a mixed method by taking a sample of the population of active users in Indonesia and using samples from several respondents, and registered users who have not made transactions

Results: It is hoped that this research will provide benefits to add insight and as a digital business reference and material for consideration for meeting daily needs in Indonesia in determining the right strategy both in business and application.
Miradas diversas para la escuela que deseamos: coeducación inclusiva con artes
Authors: Alonso Sanz Amparo
Published: April 2024

Un reto pedagógico actual es lograr entornos educativos que fomenten la igualdad en la diversidad, para la convivencia pacífica de personas de todos los géneros, edades, clases sociales, culturas, religiones, orientaciones sexuales y capacidades. El conocimiento de nuestras identidades y el respeto a todas ellas es clave para este fin. Alcanzarlo pasa por una implicación de toda la comunidad educativa, que revise sus concepciones y prácticas cotidianas. Este libro es un apoyo para observar los problemas identitarios que nos preocupan en las escuelas e institutos y, a partir de esta reflexión, promover entornos más coeducativos e inclusivos. La perspectiva feminista y la teoría de la interseccionalidad pueden ayudar a la comunidad educativa a evaluar qué valores desean compartir el profesorado, el alumnado y las familias. En su primera parte, la obra busca suscitar el pensamiento crítico planteando revisiones de los usos de diferentes espacios como los patios, las bibliotecas, los baños, los vestuarios, los comedores o las aulas, así como las violencias directas, culturales, simbólicas y estructurales que subyacen en estas tradiciones. En su segunda parte, a modo de guía, reúne propuestas pedagógicas para abordar en el aula cuestiones de identidad con alumnado infantil y juvenil en la prevención de conflictos. Las actividades que se ofrecen están fundamentadas en aportaciones de la educación artística y se basan, sobre todo, en métodos de trabajo colaborativo y aprendizaje activo.

Background and objectives: In Nigeria, there are wide use of medicinal plants for different health conditions like diabetes. Zingiber zerumbet rhizome is one such plant used for health challenges. This study assessed the effectiveness of Zingiber zerumbet in a diabetic rat model. Methods: Extraction was carried out with methanol, using cold maceration. Fractionation was carried out with n-hexane, ethyl acetate and butanol. The antidiabetic studies were done using Alloxan induced diabetic rat model. Haematological parameters and liver and kidney function enzyme levels were analyzed using standard protocols. Results: The glucose levels were reduced significantly by 68.17, 67.68, 54.29, 66.81, 77.74, 64.00, 60.89, 69.12, 62.11 and 58.26 % for 100mg/kg of Glibenclamide, 100 mg/kg crude extract, 250 mg/kg crude extract, 500 mg/kg crude extract, 250 mg/kg n-hexane, 500 mg/kg n-hexane, 250 mg/kg Ethylacetate, 500 mg/kg Ethylacetate, 250 mg/kg butanol and 500 mg/kg butanol respectively. The liver and kidney function enzymes were brought to control at p<0.05 significance. The haematological parameters were also brought to control at p<0.05 significance. Conclusion: The extract and fractions of Zingiber zerumbet rhizome exhibited potential antidiabetic effect in rat model. Further studies are required to isolate, purify, characterize and structurally elucidate the particular bioactive constituent(s) responsible for the observed antidiabetic effect.

Published: April 2024

Background: Pulmonary renal syndrome (PRS) is a diagnostic and therapeutic emergency defined by the association of alveolar haemorrhage and rapidly progressive glomerulonephritis. The primary causes of PRS are dominated by ANCA-associated vasculitis (60-70% of cases) and Goodpasture's syndrome. The pauci-immune variant of this syndrome (ANCA-negative) is rare, and its management lacking well-established guidelines. We herein present the case of a patient with renal and pulmonary manifestations of ANCA-negative vasculitis. Case presentation: A 42-year-old woman with no prior medical history presented with acute dyspnoea with hemoptysis associated with purpuric lesions on both lower limbs and macroscopic hematuria. Initial laboratory values revealed a normochromic normocytic anemia at 6.1 g/dL, CRP of 264 mg/L, renal failure with a GFR of 33 mL/min/1.73m², active urine sediment and 24-hour urine protein at 2.53g/24h. The anti-nuclear antibody was negative, and routine enzyme-linked immunosorbent assay (ELISA) were negative for MPO-ANCA, PR3-ANCA and anti-MBG. A thoracic angioscan revealed alveolar hemorrhage, while cardiac echocardiography indicated an acute cor pulmonale. Due to the patient's clinical instability, a kidney biopsy was not performed. The diagnosis of ANCA-negative vasculitis was suspected. Management of the patient required several stays in intensive care, including pulse therapy with a high dose of methylprednisolone at 1000 mg/daily for 3 days followed by oral prednisone 1 mg/kg per day, appropriate antibiothics, multiple transfusions, and plasma exchanges due to corticosteroid resistance. The patient’s clinical status showed an initial moderate respiratory improvement before succumbing to an acute respiratory failure. Conclusion: There is a pressing need to promptly establish a well-structured management approach to ensure a more favorable prognosis for this uncommon condition.

Published: April 2024

Hemangiomas are the most common benign tumors in children (10% of infants), affecting girls more than boys. It corresponds to a transient proliferation of endothelial cells fed by neo-vessels. Hemangiomas of orbito-palpebral localization affect 10 to 12% of children, requiring rapid diagnosis and management as they can be complicated by amblyopia due to mechanical ptosis and astigmatism due to compression of the eyeball. We report the case of a 7-year-old male child who presented with a swelling of the left lower eyelid, discovered at the age of one, progressively increasing in size and unimproved by beta-blockers. On examination, a bluish mass was found, with fine telangiectasias and no pain on palpation. Imaging, in particular orbital MRI, confirms the diagnosis of subpalpebral capillary hemangioma, as well as assessing its retrobulbar extension, appearing as T1 hyposignal, T2 hyperhypersignal and the site of numerous structures in "signal voids" corresponding to fast-flowing vessels, and which takes on strong contrast after injection of Gadolinium with respect for intra- and extra-conical fat and the optic nerve.

Published: April 2024

Introduction: The lower eyelid is a frequent site of basal cell carcinoma (BCC), the excision of which leaves room for loss of substance of varied characteristics which must be reconstructed. We report the case of a patient treated in our training for basal cell carcinoma of the right lower eyelid. Observation: This is a 78-year-old female patient, a farmer, without any particular ATCD, who presents an ulcerative-budding mass of the lower right eyelid measuring 2.5cm in its long axis, painless, and has been evolving slowly for 10 years. A facial CT scan revealed a lesional process infiltrating the eyelid without extending to the endo-orbital structures. A biopsy revealed sclerodermiform and nodular basal cell carcinoma. The patient underwent tumor excision with 1cm margins under general anesthesia, performing a total amputation of the lower eyelid associated with loss of jugal substance. She benefited from reconstruction using palatal fibromucosa for the posterior lamella and Mustardé temporo-jugal advancement-rotation flap for the anterior lamella and cheek. Discussion: Eyelid reconstruction constitutes a real challenge for the surgeon who must meet aesthetic and functional requirements. Several means of repair have been described in the literature. The choice falls to the surgeon who must respect the principles of eyelid reconstruction. This choice depends on the characteristics of the loss of substance and the experience of the surgeon.
