Published: December 2023

Neuromuscular disorders can lead to nocturnal hypoventilation. Accurate diagnosis of hypoventilation is imperative to guide treatment decisions. This study determined interobserver agreement for a number of definitions of nocturnal hypoventilation in children and adolescents with neuromuscular disorders. Overall mean interobserver agreement was 89% (range 66–100%); however, reliability of agreement was moderate at best (Fleiss κ = 0.574, p < 0.001). When hypoventilation was present, the objective definition used most frequently was an average increase in partial pressure of carbon dioxide (pCO2) ≥ 3 mm Hg from NREM to REM. The appearance of the transcutaneous CO2 (TCO2) trend graph and an increase in pCO2 ≥ 10 mm Hg from awake to asleep were most often associated with a false positive diagnosis. The variation and at best moderate agreement between pediatric sleep physicians observed in this study when diagnosing hypoventilation in children with neuromuscular disorders may be partially explained by the existence of multiple definitions and failure to remove artifact and “drift” from the TCO2 data.

Published: December 2023

Background and Objective The aim of our study was to evaluate the psychometric properties of the ASWS in a Turkish adolescent sample.Methods Two hundred and two Turkish high school students participated in our study. We used exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) for factor structure. McDonald’s ω and Cronbach’s α values were utilized for reliability analyses. We examined convergent validity by calculating correlations between the ASWS and sleep parameters and perceived stress scale scores.Results A 3-factor structure was detected, explaining 66.20% of the total variance with an eigenvalue above 1 in EFA. The 3-factor structure was confirmed with good fit indices in CFA. The scale demonstrated solid internal consistency (α = 0.844, ω = 0.832). We found a significant negative correlation between the ASWS and perceived stress, sleep latency, wakefulness after sleep onset, and ability to sleep after wakefulness at night.Conclusions The Turkish ASWS was found to be a valid and reliable instrument.

The main subject of this text is the study of analytic second order linear partial differential equations. We aim to solve the classical equations and some more, in the real or complex analytical case. This is done by introducing methods inspired by the Frobenius method for second order linear ordinary differential equations. We introduce a notion of Euler type partial differential equation. To such a PDE we associate an indicial conic, which is an affine plane curve of degree two. Then comes the concept of regular singularity and finally convergence theorems, which must necessarily take into account the type of PDE (parabolic, elliptical or hyperbolic) and a nonresonance condition. This condition gives a new geometric interpretation of the original condition between the roots of the original Frobenius theorem for second order ODEs. The interpretation is something like, a certain reticulate has or not vertices on the indexical conic. Finally, we retrieve the solution of all the classical PDEs by this method (heat diffusion, wave propagation and Laplace equation), and also increase the class of those that have explicit algorithmic solution to far beyond those admitting separable variables. The last part of the text is dedicated to the construction of PDE models for the classical ODEs like Airy, Legendre, Laguerre, Hermite and Chebyshev by two different means. One model is based on the requirement that the restriction of the PDE to lines through the origin must be the classical ODE model. The second is based on the idea of having symmetries on the PDE model and imitating the ODE model. We study these PDEs and obtain their solutions, obtaining for the framework of PDEs some of the classical results, like existence of polynomial solutions (Laguerre, Hermite and Chebyshev polynomials).

This research concerns with analysis of a class of modified predator- prey type Leslie-Gower models. The model is described by an autonomous nonlinear ordinary differential equation system. The functional response of predators is Holling IV type or non-monotone, and the growth of prey is affected by the Allee effect. An important aspect is the study of the point (0, 0) since it has a strong influence on the behavior of the system being essential for the existence and extinction of both species, although the proposed system is not define there.

Published: December 2023

The autonomous prey-predator system with logistic growth and Holling type II functional response, which describes the population dynamics of two species. In this study, the equilibrium points of the system (1.1) were identified. Two saddle-node points and one non-trivial P3 equilibrium point were found. For this latter point, the conditions were determined for the Jacobian matrix of (1.1), evaluated at P3, to have a pair of purely complex eigenvalues (necessary condition for the Hopf bifurcation). Through this analysis, values c0, δ0, k0 were found that satisfied these conditions. Subsequently, each of these values is considered as a bifurcation parameter value, and the remaining two are considered as control parameters, under the assumptions of the normal form theorem for the Hopf bifurcation, it’s concluded that by varying these values slightly, the system undergoes the Hopf bifurcation. Finally, the first Lyapunov coefficient was calculated to determine the conditions under which the system exhibits supercritical, subcritical, and degenerate Hopf bifurcation. The analysis was supported by using MAPLE and MATLAB software, which enabled graphical visualization of the obtained results.

Hidrogênio verde e usos múltiplos dos recursos hídricos: análise crítica de (integração de e entre) políticas públicas e legislação ambiental
Authors: Agostinho Rafaela Ueked de Alvarenga , Ribas Luíz César
Published: December 2023

A utilização dos recursos naturais não renováveis (sobretudo os combustíveis fósseis) para fins de produção de energia está acelerando os problemas ambientais, além de interferir no equilíbrio ambiental, aumentar a produção de dióxido de carbono na atmosfera e contribuir para o aumento do efeito estufa. Atualmente estão sendo discutidas, dentro do escopo das políticas públicas/ambientais, questões de proteção ambiental, social e econômica para um melhor desenvolvimento sustentável e econômico do país. As mudanças climáticas estão cada vez tomando mais destaques entre as pautas importantes da atualidade. Este trabalho será apresentado como alternativa energética mitigadora das mudanças climáticas, qual seja, a produção do hidrogênio verde (H2V) para a descarbonização do meio ambiente, substituindo a exploração de combustíveis fósseis. O objetivo deste trabalho foi demonstrar que a produção de H2V, enquanto fonte de energia limpa, deve se pautar em dispositivos normativos que promovam o uso e a conservação de recursos naturais. Desenvolveu-se uma pesquisa exploratória e documental apoiada na abordagem dedutiva de algumas das principais leis e políticas que orbitam ao redor do tema central deste trabalho. Demonstrou-se que a proteção sustentável de H2V prescinde, para tanto, da garantia do uso racional dos recursos naturais (florestais e hídricos, em especial). Esta garantia pode ser vislumbrada em dispositivos normativos tais como a nova Lei Florestal e a Política Nacional de Recursos Hídricos. Todavia, por conta de alguns “elos” de ligação (como, por exemplo, pagamento por serviços ambientais), uma série de outras normas ambientais deverão também ser referenciadas quando da produção sustentável de H2V.

Authors: Joy Ameloko
Published: December 2023

The placenta is a heterogeneous and complex organ with multiple cell types, posing a challenge for the field of maternal-fetal medicine to implement single-cell technologies for a deeper characterization of this essential organ. Several protocols use enzymes to digest the tissue and generate single cell suspension, but this approach has several shortcomings including the loss and reduced viability of cells. In this study, we describe a non-enzymatic approach to generate single cell suspensionfrom placental tissue with high yield and viability for single cell RNAsequencing.

Published: December 2023

In the current study, Eleuthrine bulbosa bulb extract was utilized to synthesize zinc oxide nanoparticles (ZnO NPs) in a simple, sustainable, and environmentally friendly manner. The bioactive compounds of E. bulbosa extract were identified by gas chromatography-mass spectrometry (GC-MS). Following synthesis of the ZnO NPs via the green method with E. bulbosa bulb extract as the reducing and capping agent, ZnO NPs were characterized using X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Ultraviolet-Visible Spectroscopy (UV-Vis), and Photoluminescence (PL) further evaluated for antibacterial and cytotoxic activities. GC-MS analysis showed the presence of phytochemical compounds acting as reducing and capping agents. The UV-Vis spectra of ZnO nanoparticles containing E. bulbosaextract showed an optical energy bandgap between 3.12 and 3.89 eV. In addition, XRD showed that the crystalline size of ZnO NPs ranged from 21 to 68 nm with a wurtzite crystal structure. FTIR analysis showed that the plant extract contains identified functional groups including alcohols, phenols, alkene, and flavonoid compounds that influenced the mechanism of bonding with ZnO NPs. Particularly, the peaks of formation of Zn-O stretching vibrations at 470 to 480 cm-1 were successfully shown. In addition, ZnO NPs displayed antibacterial activity, which was greatest against Staphylococcus aureus, and were cytotoxic to MCF-7 and MCF-10A breast cells with IC50 values of 5.540 µg/mL and 15.77 µg/mL, respectively. ZnO NPs were successfully synthesized utilizing a green method, resulting in intriguing biocompatible potential candidates for use in both biomedical and environmental fields due to their eco-friendly synthesis and nontoxic.

The development process of titanium ore deposits is always accompanied by anthropogenic changes in natural landscapes, which, in turn, leads to several negative environmental impacts. Therefore, it is necessary to monitor mining areas. This paper presents the results of satellite monitoring of the Mezhyrichne deposit territory of the Irshansk placers group, which has been developed for over 20 years. The assessment of the ecological state includes assessment of forests condition, factors impacting the microclimate and the level of pollution by iron oxides and hydroxides. Spectral indices NDVI, NDWI and leaf area index (LAI) were used to assess the condition of forests. Among the factors impacting the microclimate, values of surface temperature distribution and evapotranspiration according to the Sebal model were calculated. As a result of the study, water loss in trees was detected within adjacent areas to the mining concessions due to the groundwater flow into cones of depression, formed under the influence of quarrying. The analysis of surface temperature distribution and evapotranspiration showed a simultaneous increase in the first one and a decrease in the second one, which is a signal of negative changes in microclimate. No significant contamination of the earth’s surface with iron oxides was detected. The maximum values of the iron oxide index (IOR) are associated with the mining concession objects especially the tailings. In general, the impact of open-pit mining of ilmenite on the environment is not critical, which is due to the use of mechanical methods of ore enrichment. The main changes of the environment take place within the mining concessions, which territory is subject to mandatory restoration after exploitation is stopped. Further research is planned to involve new modern multispectral satellite data and new methods of digital information processing in combination with ground truth measurements.

It is about one of the most important characteristics of the location of the boundaries of certain soil differences in the Northern Black Sea region, which are due to the morphological, genetic, age and dynamic features of the relief earth’s surface. Using the example of six key sites covering an area of more than one thousand km2, it has been established that the distribution over the territory of a typical black soil soils of moderately slightly humus-acumulative, southern soils with low-humus-acumulative, dark-chestnut-type low-humus-acumulative soils, to a large extent depends on a number of features of the terrestrial surface, which largely determine the configuration of the boundaries of soil differences. The scientific novelty of the study lies in the fact that the location of soil catenas is not only peculiar to isolated areas of the slopes, as current views assert, but also on large areas between the regions, due to the influence of geomorphological and paleogeographic factors. The influence on the distribution of the main soil differences of the studied territory of the factors of formation of numerous and expressive, even acute angular fractures of their boundaries is traced. Such reasons include a detailed study of the complex configuration of modern contours of the sea coast, a sharp change in the location of the coastline from submeridional to latitudinal, the presence of deeply incised valleys of the Big and Small Kuyalnik (Khadzhibeysky and Kuyalnitsky estuaries), Dniester, Berezansky and Bug estuaries which causes considerable energy of a relief and distribution of processes of plane washing away, numerous fault disturbances close to surfaces of pontic limestone and accordingly difficult orientation of directions of rivers, estuaries and beams developed river valleys, which changed the nature of the landscapes. This allows to extend the formalization of soil differences on the slopes, where it is still represented by the concept of “catena”, in large areas between rivers of the northern Black Sea coast, where differences in soil types and configuration of their boundaries due to “geomorphologic environment” (morphology, genesis age and dynamics of relief) and paleogeographic events of the region, which significantly influenced the formation of “background” types of soil cover.

Authors: GÜVENER Hakan , AYHAN Emine
Published: December 2023

Son yıllarda kentsel nüfus artışı, artan kronik hastalık yükü, birinci basamak sağlık hizmetlerine erişimin azalması acil servis hizmetlerine olan talebin artmasına neden olmaktadır. Bu artış acil servislerin hasta yoğunluğuna, kullanılan ilaç ve tıbbi sarf malzemeye, tetkik hizmetlere ve maliyetlere etki etmektedir. Sağlık hizmet arzının sürdürülebilir olmasında gelir ve gider dengesinin sağlanması gerekmektedir. Bunu sağlayabilmek için başta acil servis olmak üzere hastanenin tüm bölümlerinde gelir ve giderlerin belirlenmesi, analiz edilmesi ve denetlenmesi ihtiyacı ortaya çıkmaktadır. Bu kapsamda araştırmada bir kamu üniversite hastanesinin retrospektif olarak mali, idari, teknik ve tıbbi bilgilerinin derlenmesi, incelenmesi ve değerlendirilmesi yoluyla acil servis bölümünün giderleri ile gelirlerinin belirlenmesi amaçlanmıştır. Çözümleyici ve alt grubunda yer alan kesitsel araştırma niteliğinde yapılan bu nicel çalışmada, elde edilen verilerin hesaplanmasında geleneksel maliyet yöntemi kullanılmıştır. Araştırma sonucunda acil servis bölümünün 2022 yılı toplam maliyeti 35.985.390,84 Türk Lirası (TL), gelirleri toplamı ise 28.655.369 TL’dir. Gider çeşitlerine göre en yüksek maliyetler sırası ile işçilik giderleri, tıbbi sarf malzeme giderleri, yemek giderleri ile sarf malzeme giderleridir. Acil servis bölümünün 2022 yılının tüm aylarında giderlerinin gelirlerinden fazla olduğu görülmüştür. Ortalama bir hastanın acil servis maliyeti 199,99 TL’dir. Bu maliyet acil servis kırmızı ve yeşil alan muayene ücretinin ortalama dört katıdır. Araştırmada elde edilen sonuçlar, hastane yöneticilerine finansal planlama, performans değerlendirme ve maliyet kontrollerinde yardımcı olabilir. Ayrıca sağlık hizmetlerinin fiyatlandırılmasında elde edilen bu maliyetler, karar vericilere bilimsel dayanak oluşturabilir.

Bu çalışmanın amacı, bilişsel davranışçı yaklaşıma dayalı olarak yapılandırılan çevrim içi psikolojik danışma müdahalesinin sağlık kaygısı üzerinde nasıl bir etki oluşturduğuna ilişkin danışan görüşlerini incelenmektir. Bu çalışmada nitel araştırma yöntemlerinden durum çalışması deseni kullanılmıştır. Araştırma katılımcılarını belirlemede amaçlı örnekleme yöntemlerinden ölçüt örnekleme tekniğine yer verilmiştir. Buna göre araştırmanın çalışma grubunu tanı almamış ancak sağlık kaygısı yüksek olan ve Bilişsel Davranışçı Terapi (BDT) temelli çevrim içi psikolojik danışma müdahalesine dâhil olan üç danışan oluşturmuştur. Araştırmada veri toplama aracı olarak araştırmacı tarafından geliştirilen yarı yapılandırılmış görüşme formu kullanılmıştır. Araştırma verilerinin analizi aşamasında tematik analiz yöntemine yer verilmiştir. Verilerin analizi deneme sürümü edinilen NVivo 12 paket programı ile yapılmıştır. Araştırmadan elde edilen bulgulara göre çevrim içi BDT müdahalesinin sağlık kaygısını azalttığı, daha gerçekçi düşünebilme ve bilişsel düşünce özelliklerini fark edebilme becerilerini artırdığı, sosyal ilişkileri olumlu yönde etkilediği, sorun çözme becerilerini artırdığı ve sağlık kaygısı dışındaki endişeleri de azaltmada etkili olduğu belirlenmiştir. Bunun yanında terapi seanslarına farklı yer ve mekânlardan katılabilme imkânı vermesi çevrim içi BDT müdahalesinin olumlu bir özelliği olarak değerlendirilmiştir. Ayrıca zamanı verimli kullanabilme olanağı ve yüz yüze terapiye göre daha düşük maliyetler gerektirmesi danışanlar tarafından ön plana çıkarılan diğer olumlu özelliklerdir. Bunların yanında internet kaynaklı oluşabilecek teknik aksaklıklar ve beden dilinin daha az fark edilmesi sonucu ortaya çıkabilecek dikkat dağınıklığı sorunu çevrim içi BDT müdahalesinin olumsuz yönleri olarak ortaya çıkmıştır. Çalışmanın bulgularından yola çıkılarak uygulama sahasında çalışan ruh sağlığı uzmanlarına ve araştırmacılara önerilerde bulunulmuştur.

Published: December 2023

COVID-19 ile mücadelede; hastalıkla enfekte olmuş kişilerin tespiti ve sonrasında izole edilmesi son derece önemlidir. Bu amaçla dünya genelinde kullanılan tanı testleri, çeşitlilik ve uygulama kriterleri açısından farklılık göstermektedir. Bu derlemede halk sağlığı bakış açısıyla; COVID-19 tanısı için kullanılan testler ile kimlere yönelik ve nasıl kullanıldığının yanısıra test kullanımı konusundaki yaklaşımlar ele alınmıştır. Polimeraz zincir reaksiyonu (PCR) tabanlı testler, yüksek duyarlılık ve özgüllük değerleri dolayısıyla altın standart olarak kabul edilmektedir. Farklı örnek alma yöntemlerine yönelik karşılaştırmalar yapılmakla birlikte genel görüş, nazofaringeal sürüntü yönündedir. Altın standart tanı yöntemi olarak kabul edilmesine karşın bazı dezavantajları vardır. En önemlisi sonuçlanmasının uzun sürmesi ve yüksek maliyettir. Maliyeti azaltmak için birkaç örneğin tek bir örnek gibi değerlendirilmesi yani havuzlandırılması tercih edilebilir. Bu dezavantajlara alternatif olarak hızlı antijen testleri göz önünde bulundurulabilir. Hızlı antijen testlerinin pek çok farklı piyasa formu vardır. Bu testlerin özgüllükleri ve duyarlılıklarına yönelik pek çok çalışma yapılmakta olup farklı değerler bulunmaktadır. Genel olarak özgüllüklerinin yüksek ve duyarlılığının ise daha düşük olduğu tespit edilmiştir. Hastalığın semptomatik tanısının zorluğu, bazı kişilerin hastalığı bulaştırmasına karşın semptom göstermemesi sorunları için toplum taramaları çözüm yolu olabilir. Yeni varyantların ortaya çıkması ile dünya genelinde test politikalarında değişiklikler ve farklı yaklaşımlar gözlenmiştir. Daha geniş kapsamlı tarama yapmak amacıyla testlerin tüm halka açık hale getirilmesi veya toplum taramaları yönünde çalışmalar gerçekleştirilmiştir. Ancak artan PCR test yükü dolayısıyla bazı ülkelerde test yapılacak kişilerin kısıtlanması veya hızlı antijen testleri gibi alternatif test yöntemlerinin ek olarak kullanılması gibi test politikalarının uygulanması gerekmiştir.

Published: December 2023

El balonmano, un deporte altamente dinámico y competitivo, involucra una interacción compleja de variables que influyen en el rendimiento de jugadores y equipos, entre ellas está la comunicación. Este artículo se centra en examinar la relación entre la comunicación y el entrenamiento en el balonmano durante el período 2013-2023. El objetivo de esta revisión sistemática es revelar el estado actual de la investigación en este ámbito. 12 estudios fueron exhaustivamente revisados, abordando la comunicación, el rendimiento y la formación en el contexto del balonmano a partir de una revisión sistemática siguiendo las directrices del PRISMA, recopilando evidencia de una exhaustiva búsqueda de literatura en la Web of Science, abarcando artículos publicados entre 2013 y 2023. Los resultados resaltan un interés creciente en la comunicación entre entrenadores y jugadores, especialmente enfocado en mejorar el rendimiento de los jugadores. La literatura subraya la importancia de una comunicación efectiva en la formación y el desempeño, pero se identifica una carencia en el enfoque integral de la comunicación como variable crítica. A pesar de la evidencia abundante sobre su importancia, la exploración de la comunicación en el contexto del balonmano aún está en sus etapas iniciales en comparación con otros deportes. Se concluye que existe un creciente interés en la relación entre la comunicación del entrenador y el rendimiento de los jugadores en balonmano, pero se necesita un enfoque más integral. Los entrenadores pueden utilizar esta información para mejorar la formación y el rendimiento.

Published: December 2023

El hábito deportivo resulta esencial para el descanso nocturno del adolescente de Bachillerato.  Este estudio analiza la influencia de la práctica deportiva sobre tres variables: conocimiento, calidad e higiene del sueño. Los 145 adolescentes (M = 16.72; DE = 0.74) que componen la muestra reportaron un deficiente conocimiento en nociones del sueño (SBS = 12.04), una pobre calidad del sueño (AYA-PSQI-S = 8.36) y una perfectible higiene del sueño (ASHSr = 4.26). Sin embargo, el 83.6% de los estudiantes que realizaban actividad física demostraron puntuaciones medias totales más altas en las tres variables, asumiendo diferencias significativas (p < 0.05) en las dimensiones de duración y eficiencia del sueño, en comparación al alumnado sedentario. Además, según el estudio, el ejercicio actúa como protector ante la deficitaria calidad de sueño y como impulsor de la higiene del sueño. Por su parte, la alta intensidad de la práctica de ejercicio físico está relacionada con un mejor desempeño en la dimensión de duración de sueño y un mayor autoconcepto, teniendo en cuenta que horas de práctica tardías están relacionadas negativamente con la hora de cenar, postergando el descanso. El hábito deportivo influye positivamente en el conocimiento, la calidad y la higiene del sueño adolescente; apostando por el ejercicio de fuerza, a intensidades submáximas y alejadas en la medida posible de la hora de dormir.

Authors: CANBEK OZDİL Zeliha Cansu
Published: December 2023

This study presents a straightforward and non-enzymatic approach for glucose detection utilizing aggregated gold nanorods (GNRs) based on surface plasmon resonance (SPR). The GNRs exhibited enhanced sensitivity toward glucose concentrations of up to 10 mM. The LSPR-based glucose detection method demonstrated superior sensitivity, stability, ease of use, and a convenient readout. Moreover, the LSPR detection technique can be seamlessly integrated with various sensing platforms, offering the potential to expand the sensor's range and applicability. This study highlights the promising prospects of LSPR-based non-enzymatic glucose detection and its potential for integration into diverse sensing systems. For the 10 mM glucose solution, the addition of 5.85x109 GNRs caused a 136 nm shift. On the other hand, when 50 mM glucose is added, the shift amounted to 82 nm, while adding 100 mM glucose resulted in a shift of 71 nm. This implies that at lower glucose concentrations, the degree of aggregation is greater, suggesting a heightened sensitivity to smaller concentrations. TEM images depicted the formation of the gold nanorod aggregates upon the introduction of 10 mM glucose.

Soil fertility is pivotal for agricultural productivity, and iron (Fe) is a critical micro- nutrient essential for a successful crop development. This study investigates a potential of ensemble machine-learning methods in geospatial prediction of soil Fe in Croatia. Using a dataset of 686 soil samples, three individual machine-learning methods, including the extreme gradient boosting (XGB), support vector machine (SVM), and Cubist, as well as their ensemble, were evaluated for the soil Fe predi- ction. The ensemble method outperformed the individual models, exhibiting a higher prediction accuracy expressed by the coefficient of determination (R2 = 0.578), with a lower root-mean-square error (RMSE = 0.837) and the mean absolute error (MAE = 0.550). The soil clay content emerged as the most influential predictor, followed by the sand content, pH values, and select bioclimatic variables. This study’s results demonstrate the effectiveness of ensemble machine learning in an accurate predicti- on of soil Fe content and contribute to an informed decision-making in sustainable agricultural land-use planning and management. By including the complementary machine-learning methods into an ensemble with the representative environmental covariates, a geospatial prediction aids to a reliable comprehension of soil proper- ties and their spatial variability.

Authors: Purnama Sari Ulwan , Reveny Julia , Morin Sinaga Siti
Published: December 2023

Background: The curry leaf is an Indonesian plant commonly utilized as a spice. Curry leaves are abundant in secondary metabolites, which endow this plant with numerous advantages, including antibacterial and antifungal properties, as well as the ability to reduce blood sugar levels and blood pressure. The objective of this study is to assess the efficacy of an ethanol extract derived from curry leaves in suppressing the proliferation of Pityrosporum ovale and Candida albicans fungus.
Methods: The symbiotic properties and phytochemical composition of curry leaf simplisia were examined. The antifungal efficacy of the ethanol extract derived from curry leaves was evaluated against Pityrosporum ovale and Candida albicans using the disc diffusion method. Calculate the precise values of the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC).
Results: The simplisia of curry leaf fulfills the criteria for simplisia characterization. Curry leaves possess a variety of secondary metabolite chemicals, including alkaloids, flavonoids, tannins, saponins, glycosides, steroids, and triterpenoids. The activity against the inhibition of fungal growth of Pityrosporum ovale and Candida albicans can suppress fungal growth with inhibition zone diameters measuring 6.93±0.15 mm and 7.27±0.47 mm, respectively. The minimum lethal concentration of leaf ethanol extract for Pityrosporum ovale fungi is 8.75%, resulting in a decrease of 98.25%. For Candida albicans fungi, the minimum lethal concentration is 12.5%, resulting in a reduction of 98.37%.
Conclusions: The ethanol extract derived from curry leaves has the ability to hinder the proliferation of Pityrosporum ovale and Candida albicans fungus.

Published: December 2023

An elderly man undergoing treatment for carcinoma of left buccal mucosa experienced the appearance of skin lesions on his chest, both upper limbs, and both lower limbs after receiving the first cycle of nivolumab therapy. A biopsy report confirmed that the patient had eczematous dermatitis, which was believed to be induced by nivolumab. Patient received symptomatic treatment with Prednisolone, Clobetasol propionate and Fusidic acid. The Skin lesions improved, and subsequently Framycetin cream was recommended, resulting in no further recurrence of lesion. Clinicians should remain vigilant about development of T-cell activation-related skin disorders when administrating immune checkpoint inhibitors, such as nivolumab.
Evolution of the Amyotrophic Lateral Sclerosis Diagnostic Criteria Towards the Gold Coast Criteria
Authors: Lee Sanggon
Published: December 2023

Amyotrophic lateral sclerosis (ALS) is a fatal, neurodegenerative disorder characterized by progressive degeneration of upper and lower motor neurons (LMNs). Careful history taking, neurological examination, and electromyography are used to confirm its clinical diagnosis. The El Escorial, revised El Escorial and Awaji criteria have proposed varying degrees of diagnostic probability for ALS. However, such categories may cause uncertainty among patients regarding the certainty of diagnosis. Cases labeled as “possible ALS” also risk exclusion from clinical trials. To clarify and simplify the diagnostic criteria of ALS, the previous diagnostic categories of possible, probable, and definite were abandoned in the newly suggested criteria, Gold Coast criteria. The simplified criteria offer practical utility for precise diagnosis of LMN-predominant ALS and clinical trial recruitment going forward.
PROJETO CIDADANIA:
Authors: SOARES FILHO JOSÉ , SOARES MARTINS EDSON
Published: December 2023

A presente pesquisa tem por objetivo realizar um estudo sobre o exercício direto do voto cristão protestante entre os anos de 2010 e 2020, tendo como base para nossa discussão o fenômeno surgido no seio da Igreja Evangélica Assembleia de Deus em Pernambuco, o  Projeto Cidadania. Analisaremos, de modo inicial, e a partir de Halbwachs (2006) e Pollack (1989), o processo de construção, apagamento e disputa da memória coletiva, mostrando como isso pode ser aplicado ao estudo sobre esse projeto, em vista da tentativa de apagamento da relação estabelecida entre a igreja e essa esfera político-eleitoral; na sequência, nos deteremos na análise de material de divulgação de candidatos evangélicos que concorriam ao cargo de vereadores no Estado de Pernambuco, no ano de 2012, nessa seção nos concentramos nas concepções estéticas dos gêneros do discurso de Bakhtin (2003); e, por fim, pensaremos quais elementos aproximam e distanciam esse projeto daquilo que pode ser entendido como um partido político Berstein (1998), e como elemento constitutivo e ordenador de orientação ao exercício da cidadania na escolha do candidato.
A IMPRENSA AUSENTE NA AMÉRICA PORTUGUESA
Authors: Duque Estrada de Barros Jeronimo
Published: December 2023

Resumo:

Ainda paira sobre a historiografia brasileira uma questão não completamente respondida: por que em todo o período colonial houve tão poucas tentativas de fundar oficinas de tipografias, ou seja, uma imprensa na América portuguesa? Esse artigo foca na tentativa de avaliar a influência da censura portuguesa para esse fenômeno e indica a necessidade de revisão historiográfica para o avanço das investigações sobre o tema. Prega, sobretudo, o afastamento de concepções contemporâneas que se ligam a noções de liberdade de imprensa e censura que seriam exóticas à sociedade luso-americana de Antigo Regime. O objetivo é demonstrar que a renovação historiográfica pode revelar novas perspectivas e ampliar a compreensão das condições de existência da cultura letrada da época moderna na América lusa.

Semiotics of V. Nabokov’s artistic language in the light of N. Goodman’s theory of symbolization
Authors: Shevchenkp Ekaterina , Gerchenova Daria
Published: December 2023

The article is devoted to the problems of V. Nabokov’s author’s style, considered from the standpoint of semiotics. Russian-language prose created by V. Nabokov during the Berlin period of his life is used as research material: the novels “Mary”, “King, Queen, Knave”, “The Luzhin Defense”, “Glory”, “Camera Obscura”, “Despair”, “Invitation to a Beheading”, “The Gift” and stories from the collection “The Return of Chorb”. The features of the Nabokov’s text verbal sign, as well as the visual and expressive capabilities of the verbal images in the writer’s works are considered. Thanks to the use of N. Goodman’s general theory of symbols and Aage A. Hansen-Löwe’s theory of intermediality as a methodological basis, the possibility of interpreting Nabokov’s poetics as “flickering,” metaphorical, “polycode” opens up. As a “code” of Nabokov’s images, not only verbal signs themselves are considered, but also their translation into signs of other arts that are not directly related to words - painting, cinema, architecture. As a result of the study, the authors come to the conclusion that V. Nabokov’s verbal sign strives for maximum visual expressiveness, taking on some of the properties of the iconic sign. Thanks to the chosen approach, new results were achieved in the study of V. Nabokov’s artistic language.
The phenomenon of creative self-reflection and the problem of creating a biography of the writer
Authors: Golubkov Sergey A.
Published: December 2023

The article deals with the consideration of numerous cases of the writer's self-reflection when creating his scientific biography, about the dialogical links of biography with the epoch. The creative life of an artist can develop both thanks to and despite the influence of time, or even independently of it. Attention is paid to the problem of the gradual formation of the writer, the creative person's awareness of his own mission, his socio-cultural destiny. There is an important question about the incentive motives for choosing a profession, which include a fateful meeting with a great artist, and the burden of accumulated life impressions, and the experienced psychological trauma. The importance of the writer's diverse reception of someone else's aesthetic experience is great. The attitude to this experience can be expressed as a triad: influence, repulsion, mutual enrichment. The article discusses the dual role of the creative crisis (the annoying lack of a theme, the feeling of exhaustion and frustration, the impoverishment of creative means), which can be considered not only as a failure, but also as a rare chance of a probable productive renewal. The examples of such radical renewal in the creative life of V.P. Kataev, Yu.V. Trifonov, V.F. Tendryakov in the 1960-1970s are given. In addition, the article takes into account the phenomenon of the literary generation, belonging to which can become a school for the writer and help him to determine the vector of further development, the problems of creativity, the choice of artistic language, creative manner. The author talks about the special importance of cultural generation and the own individual creative code developed by the writer, which the writer will pass on to future literary generations.
