El síndrome de Cushing es un trastorno potencialmente mortal asociado con un exceso de cortisol endógeno, que puede ser difícil de detectar, especialmente en casos leves donde los síntomas son comunes en la población en general. En los últimos diez años, se han identificado mecanismos moleculares y alteraciones genéticas vinculadas a diversas causas del síndrome de Cushing. Aunque ha habido avances en técnicas de imagen y pruebas bioquímicas, el diagnóstico y tratamiento del síndrome aún presentan dificultades. La cirugía sigue siendo el tratamiento de elección para todas las formas de la enfermedad, pero la terapia médica ha progresado significativamente con la innovación de nuevos medicamentos. En casos de hipercortisolismo grave o potencialmente peligroso, es esencial administrar tratamiento médico urgente, utilizando medicamentos por vía intravenosa o en combinación terapéutica, antes de que los pacientes puedan ser sometidos a cirugía. En esta última década, el enfoque médico ha avanzado de unos pocos inhibidores de la esteroidogénesis a tres nuevas clases de fármacos: los nuevos inhibidores de las enzimas esteroidogénicas que pueden tener menos efectos adversos, los fármacos dirigidos a la hipófisis que buscan inhibir las vías fisiopatológicas de la enfermedad de Cushing, y los antagonistas de los receptores de glucocorticoides que bloquean la acción del cortisol.

INTRODUÇÃO: A endodontia visa prevenir e tratar alterações patológicas na polpa dental e nos tecidos periapicais. Apesar das técnicas padronizadas, falhas podem ocorrer, tornando a cirurgia paraendodôntica uma alternativa em casos de insucesso endodôntico, especialmente diante de lesões periapicais persistentes. Desde os anos 1990, a microcirurgia endodôntica tem avançado com o desenvolvimento de instrumentos ultrassônicos e biomateriais, aumentando as taxas de sucesso para até 98%.RELATO DE CASO: Paciente do sexo masculino apresentou dor após tratamento endodôntico no dente 22. O exame clínico revelou uma fístula, confirmada por radiografia e tomografia, associada a uma lesão periapical causada por material obturador extravasado. Realizou-se uma cirurgia com retalho quadrangular, osteotomia exploratória e curetagem apical. Após remover 2 mm do ápice radicular, decidiu-se não realizar retrobturação, optando por encaminhamento para retratamento endodôntico. O fechamento foi feito com sutura simples, e o paciente foi orientado para acompanhamento. DISCUSSÃO:A decisão por cirurgia considerou a inflamação persistente e as limitações do retratamento convencional. Estudos indicam que fatores como resistência bacteriana e complexidade anatômica influenciam o insucesso endodôntico. A cirurgia permite o reparo de tecidos periapicais ao eliminar infecções e lesões. CONCLUSÃO: A microcirurgia paraendodôntica é eficaz em casos de insucesso endodôntico, favorecendo a preservação do dente e promovendo o reparo tecidual. O acompanhamento é essencial para avaliar a reparação e prevenir complicações

Anxiety and odontophobia represent significant barriers in the daily life of dental surgeons, directly impacting the quality and success of care. These conditions manifest at different levels and require varied management strategies, such as behavioral techniques, pharmacological sedation, and other complementary approaches. Overcoming such challenges is essential not only for the benefit of the patient, but also for the improvement of the professional's clinical practice. The present study aimed to evaluate the efficacy of conscious sedation with nitrous oxide (N₂O) in reducing anxiety and odontophobia in patients undergoing dental procedures. Five consultations were performed with conscious sedation in patients previously diagnosed with odontophobia. For the analysis, two evaluative instruments were applied: the Corah Dental Anxiety Test, used to measure anxiety levels before and after care, and the Trieger Test, used to assess changes in motor coordination resulting from sedation. In addition, vital signs, symptoms, and complications during the procedures were recorded and systematized for analysis. The results indicated that there were no significant changes in the Trieger Test scores before and after the consultations, suggesting that conscious sedation with nitrous oxide did not compromise the motor coordination of the patients. Stabilization or reduction of blood pressure was observed during the procedures, in addition to a noticeable reduction in anxiety levels, according to the data from the Corah Test. However, the intensity of odontophobia was shown to be associated with the complexity of the procedures performed. We conclude that the use of conscious sedation with nitrous oxide was effective in reducing anxiety in dental procedures, reinforcing its role as an adjuvant tool in the management of odontophobic patients. However, the results did not allow us to establish significant correlations between anxiety, age, or gender of the patients.

Energy, Debt, and Growth: Time Series Evidence on Causality in OECD European Countries
Authors: Awada Mohamed , Darwiche Joanna , Badran Moustapha
Published: December 2024

In this paper, we explore the causal relationships between energy, debt, and growth for a selection of nine OECD European countries. This examination enables us to draw lessons and deduce implications regarding the interconnections between these variables, helping us determine whether they evolve independently, or are mutually related. To conduct this analysis, we utilize annual data and employ econometric techniques, including vector-autoregressive (VAR) models, as well as Granger and Toda-Yamamoto causality tests, applied to specific countries within the group. Our key findings provide significant insights, enabling us to categorize the countries by their levels of indebtedness and energy independence. The inclusion of energy supply results in a more coherent segmentation of countries, consistent with descriptions in the literature. This classification provides a clearer understanding of the economic and energy dynamics within these nations and helps inform policy decisions aimed at managing debt levels and enhancing energy security.

Background: Innovation implies making better quality items and administrations, which together
create a superior personal satisfaction. The purpose of this study is to clarify why the Gulf
Cooperation Council (GCC) nations are as yet battling in the field of development despite the way
that the committee is comprised of wealthy nations with high per capita pay. The point of this
paper is to clarify the truth as to development in the GCC nations and to distinguish the
fundamental snags and difficulties confronting these nations. Methodology of this empirical
research embraced a systematic analysis method to control for the missing data. It utilized real
GDP, employment rates, and capital stock data. Therefore, the study adopts a review of secondary
data and analysis. Finding: in light of subjective exploration techniques, is that there are various
impediments confronting GGC nations, hindrances like low interest in innovative work as a level
of GDP, a low number of cutting edge sends out as a level of fabricated fares, and a low extent of
laborers utilized in information serious exercises. Recommendations: These discoveries affirm
that the GCC governments need to put forth incredible attempts to create development,

Analysis of a fractional-order mathematical model for occupational transition from farming to other sectors
Authors: Daimary Nobin , Paul Ranu
Published: December 2024

In this article, we developed a fractional-order mathematical model to study the dynamics of farmers transitioning to other professions, incorporating memory effects through Caputo-type fractional derivatives. We ensured the model's biological viability by proving non-negativity and boundedness of solutions, and demonstrated existence and uniqueness using fixed-point theory. The model has non-negative equilibrium points, with local and global stability conditions analyzed. The basic reproduction number R0 was determined, showing that when R0<1, the equilibrium point E1 is locally asymptotically stable. The stability of the endemic equilibrium E* was assessed using the Routh-Hurwitz criterion. The global stability of the equilibrium points is also analyzed using the Lyapunov function. Sensitivity analysis identified optimal intervention strategies, and numerical simulations confirmed the theoretical findings.

Authors: Etse Kossi Roland , Lakmon Anaté Kodjovi , Mensah Yaogan
Published: December 2024

In this paper, we study some geometric properties of the Fourier space of a hypergroup and other related Banach spaces. We are mainly concerned with the Radon-Nikodym property, the Dunford-Pettis property and the Schur property. Among other results, we proved that if H is a commutative hypergroup, then the Fourier space of A(H) has the Dunford-Pettis property; if $H$ is a compact hypergroup then A(H) has the Schur property and consequently the Dunford-Pettis property. We also showed that the Figa-Talamanca--Herz space Ap(H) does not have the Schur property if H is not compact.

Authors: Ramazanova Aysel , Taghiyev Rauf , Mehraliyev Yashar
Published: December 2024

We analyze the solvability of the inverse problem with an unknown coefficient for a fourth-order hyperbolic equation. To investigate the solvability of the inverse problem, the problem is considered in a rectangle area, with set conditions being typical of the boundary-value problem and an auxiliary condition being necessary of the unknown coefficient searching. Using the Fourier method, the problem is reduced to solving a system of integral equations, and using the compressed mapping method, the existence and uniqueness of a solution to the system of integral equations is proved. The existence and uniqueness of a classical solution to the original problem is shown.

Published: December 2024

Since the beginning of the 1990s, a renewed interest for the thermoelectric appeared, due in particular to the emergence of environmental concerns regarding the gases used in refrigeration and emissions of greenhouse gases as well as the willingness to develop alternative sources of energy. The generation of current by thermoelectric effect appears as an interesting source to relieve the problems existing energy, capitalizing on the transformation of the enormous quantities of heat lost identified for example, by cars, to useful energy. The objective of the present analysis is the study and modeling of a thermoelectric generator. In the work of realization of a thermoelectric generator, a fan has been used to cool the latter during the generation of the electric current with a speed of cooling ranging from 0 to 12 m/s. The characteristic of the energy collected at the terminals of the electrical resistance as a function of temperature is a rising curve up to a maximum value of flow (Qmax = 80.4 W) and then decreasing, so we can say that the thermoelectric a non-linear effect of temperature. The maximum value of the performance is 22.55%. Therefore 22.55% of the thermal energy is transferred into electrical energy through the thermoelectric module of a length X of the order of 0.16 m.

Dengue Hemorrhagic Fever (DHF) is an infectious disease caused by the dengue virus, transmitted through the bite of the Aedes aegypti mosquito. This disease poses a serious public health problem in tropical and subtropical regions, including Indonesia, with an increased risk of transmission, especially during the rainy season. At the Harapan Kita Orphanage, unsanitary conditions, such as scattered trash and stagnant water, were found to be breeding grounds for mosquitoes, increasing the risk of DHF transmission among the children in the orphanage.To address this issue, a community service program was carried out with the aim of educating the children and caregivers at the orphanage about DHF prevention. Through interactive counseling sessions and the use of visual aids, it was hoped that the community would better understand the symptoms, modes of transmission, and proper preventive measures. The results of this program showed an increase in awareness regarding the importance of maintaining environmental cleanliness and the implementation of preventive measures, such as the use of abate powder and proper water management.

The majority of the Borehbangle village community works as farmers, and their main need in supporting agriculture is fertilizer. However, the farmers face challenges in obtaining subsidized fertilizers from the government, causing concern. Additionally, the farmers lack the skills to process organic fertilizer into liquid fertilizer that they can utilize. Therefore, the objective of this community service is to assist farmers in improving their skills in processing organic fertilizer into liquid fertilizer that can be used in agricultural activities. The partners in this service project are the farmers of Borehbangle village and the Agricultural Service Agency (BPP) of Merakurak. The method used is Participatory Action Research (PAR), with approaches that include mapping, transect walks, field notes, seasonal calendars, Venn diagrams, flow charts, as well as historical tracing and problem trees. The community service team collaborated with BPP Merakurak to conduct training on producing organic liquid fertilizers, specifically NPK and urea. The results of this project show that the farmers actively participated in the socialization and direct training on producing organic liquid fertilizers. Moreover, they are now able to apply this knowledge independently at their homes. This training had a significant impact on improving the farmers' self-reliance in addressing fertilizer issues, ultimately supporting the sustainability of agriculture in Borehbangle village.

This community service aims to develop new Girilayu Batik motifs that combine traditional elements with modern designs, and apply them to fashion and home decor products. Through a series of stages, starting from motif development, prototyping, to market testing, this Community Service has succeeded in producing products that are well received by consumers. The results of the market test show that this new motif not only increases the aesthetic appeal but also the selling value of Girilayu Batik products. The training provided to batik artisans improves their skills in applying new motifs, as well as involving the younger generation in preserving the batik tradition. Marketing strategies through digital catalogs, company profile videos, and other digital platforms have proven effective in expanding market reach. However, this community service identified challenges in technology adaptation by artisans and international market penetration. Overall, motif innovation and product diversification are important strategic steps to maintain the relevance and competitiveness of Girilayu Batik in an increasingly competitive market.

Adapting LLMs to New Domains: A Comparative Study of Fine-Tuning and RAG strategies for Portuguese QA Tasks
Authors: da Costa Leandro Yamachita , Oliveira e Souza Filho João Baptista de
Published: December 2024

The rise of Large Language Models (LLMs) represented a significant advance in text generation applications. However, LLMs face challenges in domains outside the scope of their original training. This study investigates the following two approaches to adapt LLMs to new domains in the context of generative question-answering (QA) with data in Portuguese: fine-tuning and Retrieval-Augmented Generation (RAG). The experiments carried out in this study demonstrate the effectiveness of incorporating external data sources, even in models that had not been adjusted for the specific domain. Furthermore, the combination of supervised fine-tuning with RAG proved to be the most effective approach.
Europäische Öffentlichkeit: Entwicklungen an der Schnittstelle von Legitimations- und Kommunikationsordnung
Authors: Ingold Albert
Published: December 2024

Europäische Öffentlichkeit rückt als politischer Raum verstärkt ins Bewusstsein und wird entsprechend auch rechtlich zunehmend adressiert. Diese zumeist punktuellen Zugriffe werden aber selten in einem größeren Kontext betrachtet. Deshalb skizziert der Beitrag in einer Doppelbewegung zum einen die legitimatorischen Bezüge durch das EU-Primärrecht sowie das Außenverfassungsrecht und stellt ihnen zum anderen eine öffentlichkeitsbezogene Analyse jüngerer Rechtssetzungsakte im EU-Kommunikationsrecht – konkret der Regelungsansätze aus der DS-GVO, dem DSA und dem EMFA – gegenüber. Die Parallelisierung von Legitimations- und Kommunikationsordnung erlaubt dann abschließend Erwägungen zur Konzeptfrage europäischer Öffentlichkeit.
Kein Verlust der Unionsbürgerschaft ohne tatsächliche Möglichkeit einer Individualprüfung – Anmerkung zum Urteil des EuGH v. 25.4.2024, verb. Rs. C-684/22 bis C-686/22 (Stadt Duisburg u.a.)
Authors: Würkert Felix
Published: December 2024

Das Urteil vom 25.4.2024 betrifft in Deutschland insbesondere eine Vielzahl von Altfällen, die bei der letzten größeren Reform des Staatsangehörigkeitsrechts 1999 entstanden sind. Dabei schärft der EuGH die unionsrechtlichen Anforderungen an die Regelungen des Staatsangehörigkeitsrechts. Der Verlust kraft Gesetzes ohne faktische Möglichkeit einer Individualprüfung verstößt damit gegen das Unionsrecht, was bereits in der bisherigen Rechtsprechung angelegt war. Nun müssen mitgliedsstaatliche Stellen die Individualprüfung ggf. rückwirkend nachholen und auch die Staatsangehörigkeit rückwirkend wiederherstellen. Diesen Anforderungen genügt der neue Art. 30 Abs. 1 S. 5 StAG nicht, der jedoch nicht Gegenstand des Verfahrens war.
Нейтрализация и преодоление негативного влияния ключевых поведенческих паттернов частных инвесторов на процесс и результаты инвестирования
Authors: И.В. Горбунов
Published: December 2024

в условиях повышенной волатильности финансовых рынков особенно остро встает вопрос негативного влияния различных поведенческих паттернов инвесторов на результаты инвестиций. Важными составляющими биржевой торговли являются психологические факторы, многие из которых инвесторы не умеют или не в состоянии распознать, а также эффективно контролировать. Данные факторы приводят к искаженной интерпретации получаемой инвестором информации, неверному установлению и толкованию причинно-следственных связей, а рациональность действий инвестора оказывается под серьезным сомнением. В статье автор анализирует функционирование разных типов мышления во время принятия инвестиционных решений, рассматривает ключевые поведенческие уязвимости инвесторов, описывает их воздействие на инвестиционный процесс и предлагает способы снижения риска ошибок, вызванных психологическими факторами. Также в статье выявлены основанные на эмпирических наблюдениях поведенческие паттерны, наиболее часто встречающиеся в процессе инвестирования, предложены практические рекомендации по нейтрализации их негативного влияния, а также варианты адаптации инвесторов и их биржевой торговли к таким свойствам финансовых рынков, как скорость изменений и масштабируемость.

in conditions of increased volatility of financial markets, the issue of negative impact of various behavioral patterns of investors on investment results is particularly acute. Psychological factors are important components of stock exchange trading, many of which investors are unable to recognize and effectively control. These factors lead to distorted interpretation of the information received by the investor, incorrect establishment and interpretation of cause-and-effect relationships, and the rationality of investor's actions is seriously questioned. In the article the author analyzes the functioning of different types of thinking during investment decision-making, considers key behavioral vulnerabilities of investors, describes their impact on the investment process and suggests ways to reduce the risk of errors caused by psychological factors. The article also identifies behavioral patterns, based on empirical observations, most frequently encountered in the investment process, offers practical recommendations for neutralizing their negative impact, as well as options for adapting investors and their stock trading to such properties of financial markets as speed of change and scalability.

Published: December 2024

в настоящей статье рассмотрены сложные задачи системных преобразований бюджетной сферы, направленных на обеспечение долгосрочной сбалансированности и устойчивости всех уровней бюджетной системы страны, определяют необходимость укрепления финансовых основ местного самоуправления как важного фактора социально-экономического развития муниципальных образований. В этой связи выявление проблем и перспектив такого укрепления имеет особое значение для последовательного осуществления бюджетных реформ, влияющего на муниципальную экономику и, в конечном итоге, на благосостояние граждан. Целью исследования является выявление проблем и обоснование основных направлений укрепления финансовых основ местного самоуправления в России. В нынешней ситуации, характеризующейся замедлением экономической динамики и ужесточением финансовых ресурсов страны, важным фактором повышения стабильности и баланса бюджетной системы страны является повышение эффективности муниципального управления финансами за счет укрепления финансовой базы местного самоуправления. Это влечет за собой разработку всеобъемлющего механизма, включая нормативные меры и стимулы для адаптации к нынешней системе налогообложения межбюджетных отношений, а также формирование эффективной финансовой политики муниципалитетов.

In this regard, the identification of problems and prospects for such strengthening is of particular importance for the consistent implementation of budget reforms that affect the municipal economy and, ultimately, the well-being of citizens. The purpose of the study is to identify problems and substantiate the main directions for strengthening the financial foundations of local self-government in Russia. In the current situation, characterized by a slowdown in economic dynamics and a tightening of the country's financial resources, an important factor in increasing the stability and balance of the country's budget system is to increase the efficiency of municipal financial management by strengthening the financial base of local government. This entails the development of a comprehensive mechanism, including regulatory measures and incentives to adapt to the current system of taxation of inter-budgetary relations, as well as the formation of an effective financial policy of municipalities.
