Authors: GÜREL Musa , BİLGİSEVEN Emre , AKTÜRK İlker , YAMAN Ömer Miraç
Published: January 2024

This study aims to thoroughly examine the processes through which individuals who use substances access these substances. The main focuses of the study are the channels and locations of substance access, the process leading from substance use to procurement, communication with sellers, and applied privacy strategies. This research is designed according to qualitative research methods. During data collection, a semi-structured interview form was preferred, and interviews were conducted with 10 substance users. The collected data were analyzed using descriptive analysis methods, and the results were interpreted. The findings are presented under four themes: "Initiation of Substance Use, Methods of Accessing Substances and Privacy Strategies, Language and Trust Relationships in the Substance Acquisition Process, Locations for Substance Procurement, Risky Situations, and Social Consequences." According to the results of the study, it is highlighted that the process of starting substance use due to curiosity and experimentation, often influenced by social environment and friendships, turns into addiction, and individuals usually begin using substances between the ages of 14 and 18. The study finds that while experienced users resort to traditional neighborhood channels like street dealers, the new generation prefers social media platforms (such as Telegram, Instagram, WhatsApp, Facebook) and certain games (like PUBG mobile, Minecraft) as covert channels. It has also been determined that the language and communication methods used in the process of procuring substances are developed using various names and jargons specific to different substances. On the other hand, the need to secure financial resources for continuous consumption and procurement during the transition from substance use to procurement often leads individuals to illegal actions such as theft, robbery, and violence, as well as to dangerous and risky behaviors.
Dysfunctional Breathing – View of Otorhinolaryngologist
Authors: Šereg Bahar Maja
Published: January 2024

Background. Dysfunctional breathing – vocal cord dysfunction (VCD) or paradoxical vocal fold movement (PVFM) is inappropriate vocal fold movement. Adduction of the vocal folds appears during inspiration, resulting in dyspnea and inspiratory and sometimes expiratory stridor, and acute upper airway obstruction. It is a functional disorder, an important mimicker of asthma, leading to unnecessary morbidity and high medical utilization, unnecessary drug use, and high-dose corticosteroid use. The gold standard test for diagnosis of VCD is direct visualization of the vocal folds by laryngoscopy while a patient has symptoms or is combined with special maneuvers that trigger symptoms. Methods. The recent papers on vocal cord dysfunction were reviewed. Results. VCD is an important differential diagnosis of refractory asthma, that is widely unrecognized. But concomitant vocal cord dysfunction and asthma are seen in a high degree of patients, up to 50%. VCD is a benign and self-limiting disorder and there are no long-term sequelae. Correct diagnosis is important due to proper treatment. The cornerstone of the VCD treatment is speech therapy like respiratory retraining, learning breathing techniques, and different maneuvers that enable quick release of symptoms. Psychotherapy and hypnosis are important modes of treatment as well. Medications and botulinum toxin are used rarely. Conclusions. We should suspect VCD in patients with asthma-like symptoms that do not respond to conventional asthma therapy or are induced by stress and exercise. A team of different specialists is necessary to find the correct diagnosis and proper treatment.

Juvenile neuronal ceroid lipofuscinosis (or Batten disease) is an autosomal recessive, rare neurodegenerative disorder that affects mainly children above the age of 5 yr and is most commonly caused by mutations in the highly conservedCLN3gene. Here, we generatedcln3morphants and stable mutant lines in zebrafish. Although neither morphant nor mutantcln3larvae showed any obvious developmental or morphological defects, behavioral phenotyping of the mutant larvae revealed hyposensitivity to abrupt light changes and hypersensitivity to pro-convulsive drugs. Importantly, in-depth metabolomics and lipidomics analyses revealed significant accumulation of several glycerophosphodiesters (GPDs) and cholesteryl esters, and a global decrease in bis(monoacylglycero)phosphate species, two of which (GPDs and bis(monoacylglycero)phosphates) were previously proposed as potential biomarkers forCLN3disease based on independent studies in other organisms. We could also demonstrate GPD accumulation in human-induced pluripotent stem cell–derived cerebral organoids carrying a pathogenic variant forCLN3. Our models revealed that GPDs accumulate at very early stages of life in the absence of functional CLN3 and highlight glycerophosphoinositol and BMP as promising biomarker candidates for pre-symptomaticCLN3disease.

Published: January 2024

Pesticides residue determination in fruits like chlorpyrifos is important due to its health effects on humans. Thus, there is a need for sensitive and accurate methods for better quantification. In this study, the performance of two gas chromatographic detection methods, nitrogen phosphorus detector (GC-NPD) and isotope dilution triple quadrupole mass spectrometer (GC-IDMS/MS), for the determination of chlorpyrifos in mango was evaluated to be used for the development of candidate reference material. Other than liquid-liquid extraction (LLE), Quick, Easy, Cheap, Efficient, Rugged and Safe (QuEChERS) sample extraction and dispersive solid phase extraction (dSPE) clean-up procedures were optimized to extract chlorpyrifos from the sample matrix. Comprehensive method validations were performed in GC-NPD and GC-IDMS/MS with HP-5 capillary column to establish linearity, the limit of detection (LOD), the limit of quantification (LOQ), accuracy, repeatability, and intermediate precision using freeze-dried mango samples. The LOD and LOQ were 2.35 and 3.47 Âµg kg-1  for GC-NPD, and 1.23 and 1.85 Âµg kg-1 for GC-IDMS/MS, respectively. Matrix-matched calibration curves showed excellent linearity of r2=0.999 for both GC-NPD and GC-IDMS/MS protocols. Acceptable repeatability was obtained for three spike concentrations of 10, 30, and 60 Âµg kg-1 (n=10) and intermediate precision for 0.5-, 1- and 3-months in the same three-spike concentrations (n=3) expressed as relative standard deviation (RSD) ranging from 0.34-5.61 % for GC-NPD and 0.46-4.22 % for GC-IDMS/MS. Satisfactory mean recoveries (n=10) were achieved: 88.48-109.81% in GC-NPD and 97.61-108.40% in GC-IDMS/MS. GC-IDMS/MS and GC-NPD methods were fit for the purpose of quantifying chlorpyrifos in Philippine mango accurately with the use of isotope dilution technique and traceability to international standards by the application of gravimetric sample preparation.
Atomic Ontology in the Chemistry Curriculum and Implications for Optimizing Chemical Atomism in Teacher Education in Ethiopia
Authors: Abayneh Lemma , Woldie Belachew
Published: January 2024

This study is aimed at examining how the atom is ontologically presented in the curricular documents of teacher education in accordance with the persistence of the oldest notion of the atom and its corresponding ontological deviation. It involved content analysis of three curriculum frameworks and four modules through the interpretative coding approach of Merriam's qualitative case study. Accordingly, the curriculum was found to portray the outdated mechanical ontology as much as it endorses the targeted operational ontology. Even the operational ontology was found to controversially exhibit the mereological, functional and desired chemical notions. Though the narrative is more accurate in figurations of observable properties and phenomena, it is extremely problematic in its style and argumentation. Most of the arguments lack a solid foundation and the essential connections to the desired data, evidence, and contexts of those historical, philosophical, and scientific inquiries. This implies that issues of having an ontological basis, choice of words, and aligning corresponding components of argumentation with historical, philosophical, and scientific evidence and contexts must all be taken seriously for the curriculum to portray the targeted ontology and notion of chemical atomism.

Published: January 2024

Protein-stabilized metal nanoparticles have been receiving significant attention because their optical properties could be used for sensing applications. This study describes the synthesis of gold nanoparticles (AuNPs) stabilized with salt-soluble proteins extracted from wheat flour, and their use in the fluorescence-based detection and quantification of folic acid. The salt-soluble protein extract from defatted wheat flour contained at least eight components with molecular weights ranging from 7.26 to 57.0 kDa. The extract was made alkaline and then mixed with a HAuCl4 solution to synthesize the AuNPs. The wheat-AuNPs were red in color and had a surface plasmon resonance (SPR) peak at 519 nm. Based on the UV-visible spectrum, the AuNPs may have ~3.4 nm average size. The AuNPs exhibited fluorescence emission at 734 nm upon excitation at 365 nm. The fluorescence quenching of the AuNPs observed upon incremental addition of folic acid (0 to 10 Î¼g mL-1) was fitted to the Stern-Volmer equation. From the Stern-Volmer plot, the limits of linearity (LOL), detection (LOD), and quantitation (LOQ) were determined as 22.0 Î¼g mL-1, 0.92 Î¼g mL-1, and 3.1 Î¼g mL-1, respectively. Several substances, including some metal ions, were tested for their effects on the AuNPsâ€™ fluorescence. Moreover, a proposed fluorescence-based folic acid quantification was evaluated by determining the folic acid content of several pharmaceutical formulations.
Avaliação da interleucina-6 e do metabolismo do ferro em 20 cães saudáveis
Authors: Medeiros Nina da Cunha , Locatelli Dittrich Rosangela
Published: January 2024

Em processos inflamatórios ocorre aumento da circulação de interleucina-6 (IL-6), citocina pró-inflamatória que estimula a produção de hepcidina. Este hormônio regula o metabolismo do ferro, diminuindo sua absorção intestinal e indisponibilizando o ferro no interior das células. A principal consequência destas alterações é a anemia por indisponibilidade deste mineral. Para auxiliar no diagnóstico, determinação do prognóstico e guiar decisões terapêuticas, a avaliação laboratorial do metabolismo do ferro, hepcidina e IL-6 são de grande valia. O presente estudo objetivou avaliar a concentração sérica de ferro, capacidade latente de ligação do ferro (CLLF), capacidade total de ligação do ferro (CTLF), índice de saturação da transferrina (IST), IL-6 e hepcidina em cães saudáveis. Foram avaliados 20 cães adultos sadios sem especificação de raça e sexo e apresentando proteína C reativa abaixo de 10 mg/L. A concentração de ferro e a CLLF foram avaliadas por método colorimétrico utilizando Ferene, em seguida CTLF e IST foram calculadas. A determinação da concentração sérica de IL-6 e hepcidina foram realizadas por Ensaio de Imunoabsorção Enzimático (ELISA) utilizando kits específicos para a espécie canina. Os valores médios obtidos foram: ferro sérico = 157,75 µg/dL; CLLF= 270,41 µg/dL; CTLF = 425,61 µg/dL; IST = 36% e IL-6 = 0,164 ng/mL. Das 20 amostras avaliadas apenas uma apresentou leitura para hepcidina (16,9 ng/mL). Não houve correlação entre as concentrações séricas de IL-6 e a concentração sérica de ferro, CLLF, CTLF e IST, sugerindo que variações fisiológicas desta citocina não interferem no metabolismo de ferro de cães saudáveis.

Published: January 2024

A platinossomíase é uma infecção parasitária causada pelo trematódeo Platynosomum spp., encontrado no fígado de gatos domésticos. O felino é o hospedeiro definitivo e a severidade da doença depende da quantidade de parasitos, tempo de parasitismo e resposta do hospedeiro. O objetivo deste trabalho foi relatar um caso de icterícia pós-hepática em um gato decorrente de platinossomíase. Um gato, macho, jovem, sem raça definida, foi recebido para exame pós morte com histórico de icterícia grave, emagrecimento progressivo e morte repentina. Uma amostra de conteúdo biliar foi submetida ao método de sedimentação por centrifugação para a busca de ovos de helmintos, que revelou numerosos ovos marrom-escuros, ovais, monoperculados e embrionados, morfologicamente compatíveis com ovos de Platynosomum. O exame direto do fígado em estereoscópio e a histopatologia confirmaram a parasitose sob a identificação de formas adultas do parasito que apresentavam características morfológicas compatíveis com Platynosomum illiciens. As lesões histológicas incluíram colangio-hepatite, ectasia com obstrução ductal, fibrose, regeneração micronodular e lipidose. A icterícia pós-hepática foi relacionada à estase biliar resultante do acúmulo de muco e parasitos. Neste caso, os achados macroscópicos (icterícia intensa, fibrose hepática e colestase extra-hepática obstrutiva) e histológicos associados à identificação de parasitos adultos recuperados dos ductos biliares foram fundamentais para o diagnóstico definitivo da doença.

O objetivo do presente trabalho foi avaliar diferentes concentrações de conídios do fungo Duddingtonia flagrans (AC001) e hipoclorito de sódio (NaOCl) a 5% (v/v) sob a eclosão de ovos de nematódeos gastrintestinais de equinos. Foram formados cinco grupos experimentais: Grupo 1 (3 x 106 conídios de AC001 + 20 g de fezes), Grupo 2 (6 x 106 conídios de AC001 + 20 g de fezes), Grupo 3 (9 x 106 conídios de AC001 + 20 g de fezes), Grupo 4 (5 mL de hipoclorito de sódio 5% (v/v) + 20 g de fezes) e Grupo 5 (5 mL de água destilada + 20 g de fezes). Em seguida, as coproculturas foram incubadas por 10 dias no escuro 26 ± 1° a 2°C e, posteriormente, procedeu-se a recuperação de larvas infectantes (L3) de nematódeos por meio da técnica de Baermann. Ao final do período experimental, constatou-se a presença absoluta de L3 de nematódeos ciatostomíneos. Os resultados demonstraram que houve redução significativa (p<0,01) na recuperação de L3 em todos os grupos tratados com o AC001 (G1, G2 e G3) e também com o hipoclorito de sódio a 5% (v/v) (G4) em relação ao grupo controle (G5). Notou-se que não houve diferença (p>0,01) entre as três concentrações de conídios testadas nos grupos G2 e G3. Conclui-se que o fungo D. flagrans e o hipoclorito de sódio a 5% (v/v) foram eficientes na redução de L3 de nematódeos gastrintestinais nas coproculturas, podendo esse resultado ser utilizado em futuros delineamentos experimentais.

Comparing The Effects of Metformin and Exercise-Based Lifestyle Interventions for Symptom Management of Polycystic Ovary Syndrome (PCOS): A Literature Review
Authors: Gao Angela , Wen Jean-Ren
Published: January 2024

Introduction: Polycystic ovary syndrome (PCOS) is a common hormone problem characterized by androgen excess and typically leads to the development of small cysts in the ovaries, insulin resistance, hirsutism, irregular menstrual cycles, and hyperandrogenism. While there is no cure for PCOS, treatments like metformin and lifestyle modifications work to manage individual symptoms. While studies in the past have compared individual effects of metformin and lifestyle modifications on symptoms of PCOS, a limited number of studies have compared the effects of metformin with lifestyle modifications, specifically aerobic exercise. This review compared the effects of metformin treatment and exercise interventions on metabolic symptoms, such as high blood glucose and insulin levels in PCOS. Methods: A literature search using Pubmed and Google Scholar was conducted. A total of five articles focusing on metformin were included in the review; some focusing inclusively on the drug itself, others comparing lifestyle modifications alone and modifications combined with metformin. In this review, the lifestyle modification was aerobic exercises, taking the form of exercise regimes (walks, marching in place, or supervised fitness sessions). Results: Results show that metformin improves metabolic symptoms, including blood glucose and insulin levels, significantly more than lifestyle interventions alone; however, if both treatments were combined, these effects were more profound. Discussion: Metformin serves as an effective treatment for metabolic and hormonal symptoms, consequently improving PCOS symptomology. Although exercise is shown to be less effective than metformin, the addition of exercise to metformin treatment further ameliorates symptomology. Conclusion: Combining metformin and aerobic exercise demonstrates the greatest impact on managing PCOS symptoms. Future studies should examine the standardization of an aerobic exercise regimen and pharmaceutical treatments for the management of PCOS.

Published: January 2024

The subject of the research is the evolution of scientific approaches to the study of the spatial development of Russia. The purpose of the work is a substantive examination of the strategic planning tools as a leading institute as part of the scientific foundations of spatial development management in Russia. The article presents the technology of development and practice of execution of strategic documents for the development of the country and regions, national projects and target programs at various levels. To determine the role of strategizing in the management of spatial development, the scientific works of Russian scientists are analyzed in historical retrospect. The key role of economic and geographical research of the Soviet period in the formation of regional science is substantiated. The problems of spatial research in the modern history of Russia are presented. The development of the program-target approach is shown and the reasons preventing the coordinated functioning of the strategic planning system are identified. A number of factors complicating the implementation of national projects and state programs have been identified, including the lack of operational data, the limitations of the information system, the imperfection of the tools used for economic and financial regulation, insufficient consistency of decision-making in a hierarchically structured management sphere, etc. The necessity of applying organizational and economic innovations, activation at a qualitatively higher level of activities aimed at training specialists in regional studies and regional economics in the context of the development of international integration is argued. Conclusions are drawn about the expediency of updating the theoretical basis of regional economic disciplines and strengthening the practical training of students to work with the tools of strategic management and territorial development planning.

Published: January 2024

Certain integrals are integrals that handle integral computations between predetermined integral boundaries. This study aims to evaluate and compare several methods to calculate certain integrals numerically, especially for quite complex and tabulated functions, namely the function f(x), which is not explicitly known. The methods in question include the Trapezoidal method, the Simpson 1/3 method, the Simpson 3/8 method, and the Newton-Cotes method of orders 4 to 10. The main factor in comparing the methods mentioned above is the accuracy of the numerical solution. This study shows that for integral problems that can be calculated analytically, the results of calculations using the Newton-Cotes method of order 6 and with many partitions of 12 ( n = 12), the error is 0.0000026%. In contrast, with the Newton-Cotes method of order 6 and with n = 30, the error is 0.000000002 %, while with the Newton-Cotes method of order 10 and using n = 30, the error is 0.00000000 %.

Published: January 2024

La ferrita de lantano (LaFeO3), un cerámico con estructura tipo perovskita, es un material multiferroico que resulta atractivo por su uso en dispositivos electrónicos. A pesar de esto, presenta un orden anti-ferromagnético (AF) provocando que su magnetización específica sea pequeña a temperatura ambiente. Una manera de modificar las propiedades magnéticas es distorsionando su estructura cristalina, lo cual afecta la orientación de los momentos magnéticos. En este trabajo se modificó el orden anti-ferromagnético por medio de sustitución de cationes de Fe3+ por cationes Co2+ obteniendo LaCoxFe1-xO3 donde (0 ≤ x ≤ 0.125, Δx = 0.025). La síntesis se realizó por medio de molienda mecánica de alta energía y tratamiento térmico a 1200 °C durante 5 h. Mediante difracción de rayos X se confirmó la introducción del Co2+ en la estructura cristalina de la LaFeO3. La caracterización de magnetometría de muestra vibrante mostró que el Co2+ modifica el orden magnético, presentando ferromagnetismo débil. Por otro lado, el comportamiento dieléctrico, muestra una disminución general para las muestras dopadas a frecuencias menores a 104 Hz.

Darülmuallimatlar, geç Osmanlı modernleşmesinde kız öğrencilere eğitim vermesi için kadın öğretmen yetiştirmek amacıyla Osmanlı Devleti tarafından faaliyete geçirilmiş eğitim kurumlarıdır. 1870’te kurulan İstanbul Darülmuallimatı yaklaşık 40 yıl kadar tüm Osmanlı coğrafyası için kadın öğretmen yetiştiren tek kurum olmuştur. 1913 senesine gelindiğinde taşrada da Darülmuallimatlar açılmaya başlamıştır. Kadınların hem eğitim alma hem de verme hakkını kazandıkları bu yeni eğitim kurumlarının mekânsal üretimleri de bu süreçte gerçekleştirilmiştir. Bu okullar, izlenen politikalarla bağlantılı olarak mimari ve inşai faaliyetler açısından çok sayıda yenilikle karşılaşılan Geç Osmanlı döneminde Osmanlı mekân üretim alışkanlıklarını ve uygulamalarını anlamak için önemli bir örnekleme grubu oluşturmaktadır. Makalenin amacı da bu okullar için nasıl mekân üretildiğini ortaya koymaktır. Bu amaç doğrultusunda çalışmada kadınlar için özel olarak kurulmuş bu eğitim kurumlarının mekânsal olarak nasıl tahayyül edildiği, mekânsal üretiminde nasıl bir yaklaşımın sergilendiği, mekanlarının işlev, ölçek ve kullanıcı profiliyle nasıl ilişki kurduğu sorgulanmıştır. Bu sorgulamada kadın eğitim kurumlarına ilişkin izlenen politikalar, alınan kararlar ve bu kurumların işleyişlerine ilişkin düzenlemeler önemli ipuçları vermektedir. Arşiv belgelerinden elde edilen bilgilerle birlikte Darülmuallimatların mekânsal üretiminde yeni bina inşasının yanında, mevcut binaların dönüştürülmesi üzerinden yapılan uygulamalar incelenerek, Osmanlı mekân üretim alışkanlıklarıyla “inşa” ve “tahsis” olarak adlandırılan mimarlık pratiklerinin ilişkisi ortaya konmuştur.

Published: January 2024

The accelerating ecological crisis affecting all human beings around the world has made existing social problems such as inequality, marginalization and violence more visible, and there is now a shared understanding that ecological and social crises are fundamentally one problem that requires a unified effort. This study aims to establish the foundation to systematize the characteristics of ecocitizenship of the 21st century by examining the Transition Town Movement in Brazil as an example of ecological transition and analyzing the values shared by ecopedagogy, which seeks a new educational paradigm, and the Transition Town Movement. The fundamental purpose of this study is to explore what philosophical and practical orientations ecocitizenship have and how it differs from existing approaches to addressing inequality. To this end, this article analyzed the Transition Network website, the global umbrella organization for the Transition Town movement, the Transition Brazil website, and further related literature. It then focused on identifying the goals and main characteristics of ecopedagogy, focusing on the Pedagogia da Terra of Moacir Gadotti, a pioneer of ecological pedagogy in Brazil. The results of the study revealed a set of shared values at the intersection of the Transition Town Movement and ecopedagogy. Meanwhile, while the Transition Movement in the U.K. was centered in middle-class neighborhoods, in Brazil it started in the favelas of São Paulo and Rio de Janeiro. And it was found that Transition Town Movement and ecopedagogy do not specifically target the poor, but presuppose their active participation as the same as other citizens, and consequently practice a more constructive approach to inequality.
