Authors: ÇOPUROĞLU Filiz
Published: October 2022

Çevrimiçi mağazaların, e-ticaret platformlarının artışı pazarın küreselleşmesine neden olurken bir taraftan işletmelerin uluslararası yönelimlerini, bir taraftan da küresel rekabeti tetiklemektedir. Küresel rekabetin bu denli yoğunlaştığı bir çağda tüketicinin satın alma kararları ve değerlendirmeleri açısından marka adı, ülke algısı vb. gibi birçok parametre arasından menşe ülke en önemlileri arasında dikkat çekmektedir. Geleneksel pazarlama iletişimi araçlarının etkinliği azalırken, yeni nesil dijital tüketicilere hitap eden “çevrimiçi etkileyiciler” daha da dikkat çekmektedir. Bu bağlamda bu çalışmanın amacı fenomen pazarlaması ve satın alma niyeti arasındaki ilişkiye menşe ülke etkisinin aracılık etki edip etmediğini belirlemektir. Çalışmanın amacı doğrultusunda bir devlet üniversitesinin iletişim fakültesinde öğrenim gören öğrenciler ana kütle olarak seçilmiş ve 256 katılımcıdan elde edilen veriler istatistik programları aracılığı ile analiz edilmiştir. Yapılan analizler sonucunda fenomen pazarlaması ile satın alma niyeti arasında ve satın alma niyeti ile menşei ülke etkisi arasında orta düzeyde ve pozitif yönlü bir ilişki olduğu; fenomen pazarlama ile menşei ülke etkisi arasında ise düşük düzeyde ve pozitif yönlü bir ilişkili olduğu tespit edilmiştir. Bunun yanında fenomen pazarlamasının ve menşei ülke etkisinin, satın alma niyetindeki değişimin %32,77’lik kısmını açıkladığı sonucuna ulaşılmıştır. Buna göre menşei ülke etkisinin, fenomen pazarlamasının satın alma niyeti üzerindeki etkisine kısmi olarak aracılık ettiği bulgusu tespit edilmiştir.

Bu çalışmada Türkiye'deki emeklilik planı yatırımcılarının yatırım tercihleri, portföy dağılımları ve getirileri, yüksek kapsamlı idari verilerle, Aralık 2019 ay sonu değerleri ile ampirik olarak analiz edilmiştir. Prim ödemeli emeklilik planı yatırımcılarının portföy tercihlerini analiz edebilmek amacıyla, portföylerdeki hisse senetleri, borçlanma araçları ve standart fonlar üzerindeki yoğunlaşmalar incelenmiştir. Sonuçlar, emeklilik portföylerinde; hisse senetleri, borçlanma araçları ve standart fonların ağırlıklarının heterojen olduğunu göstermektedir. Ancak portföy getirileri için bu tespit geçerli değildir. Ayrıca, emeklilik birikimlerinin miktarlarında yüksek bir eşitsizlik gözlenmektedir. Portföyler içerisinde yer alan hisse senedi fonlarının ağırlıklarının da çok küçük olduğu tespit edilmiştir. Borçlanma araçlarının fon ağırlıkları daha yüksek olsa da, bu durum borçlanma araçları için de geçerlidir. Bunun aksine, portföylerde standart fonlarının portföy ağırlıklarının, hisse senedi ve sabit getirili fonlara göre çok yüksek tespit edilmiştir. Bu sonuçlar, Türk emeklilik yatırımcılarının standart fonlara bağlılığının yaygın olduğunu göstermektedir. Bu durum ABD ve İsveç gibi bazı gelişmiş ülkelere odaklanan literatürle paralellik göstermektedir.
Estigma e paradoxo:
Authors: Dantas Lemos Daniel , Duarte da Silva Mantuano Giovanna
Published: October 2022

O presente trabalho visa a explicitar o problema da exclusão dentro de uma Escola Libertária Freinet, a Camafeu. O problema da exclusão é visto sob a ótica de dois sistemas conceituais, o de Gilberto Velho: “Desvio e Divergência” (1979) e o de Erving Goffman: “Estigma: notas sobre a manipulação da identidade deteriorada” (2004). O trabalho se relaciona a dois conceitos desses autores: o desvio e o estigma, respectivamente. Dentro desses dois agentes conceituais discursivos, trabalhamos o desvio como algo que foge à regra vigente, seja pela via do sujeito, seja pela via institucional. Já o estigma é aplicado aos sujeitos como algo ou aquilo que não corresponde às expectativas vigentes da norma social – as pessoas portadoras de alguma deficiencia (física, mental ou intelectual), por exemplo. São dentro desses dois planos (desvio e estigma) que observamos, pois, a exclusão dos estudantes. Através das práticas de sociabilidade observadas na Escola, desenvolvemos uma observação na qual foi possível utilizar-se de questionários e vivências in loco, com base no exercício etnográfico, em um período de 10 meses. Foram investigadas as moralidades que permeiam o espaço escolar e levantada a questão: “é possível haver exclusão social dentro de um espaço libertário?”. A principal hipótese é que por mais que a instituição seja libertária e tipicamente desviante, ela não resolve o problema da exclusão, pois as grandes transformações viriam, na verdade, das relações estabelecidas no interior das salas entre os próprios alunos e não pela pretensa metodologia inclusiva.
White Matter Damage in Alzheimer’s Disease: Contribution of Oligodendrocytes
Authors: Zhou Jinyu , Zhang Peng , Zhang Bo , Kong Yuhan
Published: October 2022

Alzheimer’s disease (AD) is an age-related neurodegenerative disease seriously influencing
the quality of life and is a global health problem. Many factors affect the onset and development of
AD, but specific mechanisms underlying the disease are unclear. Most studies investigating AD have
focused on neurons and the gray matter in the central nervous system (CNS) but have not led to effective
treatments. Recently, an increasing number of studies have focused on white matter (WM). Magnetic
resonance imaging and pathology studies have shown different degrees of WM abnormality during
the progression of AD. Myelin sheaths, the main component of WM in the CNS, wrap and insulate
axons to ensure conduction of the rapid action potential and axonal integrity. WM damage is characterized
by progressive degeneration of axons, oligodendrocytes (OLs), and myelin in one or more areas of
the CNS. The contributions of OLs to AD progression have, until recently, been largely overlooked.
OLs are integral to myelin production, and the proliferation and differentiation of OLs, an early characteristic
of AD, provide a promising target for preclinical diagnosis and treatment. However, despite
some progress, the key mechanisms underlying the contributions of OLs to AD remain unclear. Given
the heavy burden of medical treatment, a better understanding of the pathophysiological mechanisms
underlying AD is vital. This review comprehensively summarizes the results on WM abnormalities in
AD and explores the relationship between OL progenitor cells and the pathogenesis of AD. Finally, the
underlying molecular mechanisms and potential future research directions are discussed.
How Medium Affects the Activity and Stereopreference of Thermoanaerobacter
ethanolicus Secondary Alcohol Dehydrogenase Catalyzed Reduction
of Ketones
Authors: Karume Ibrahim , Bbumba Simon , Tewolde Simon
Published: October 2022

The activity and selectivity of W110G Thermoanaerobacter ethanolicus secondary alcohol
dehydrogenase were altered by cosubstrate and cosolvent at varying temperatures. A sharp drop in the
enantiomeric excess (ee) was observed at 60 oC in the first 3 h, suggesting increased selectivity mistakes
in the reduction of 4-phenyl-2-butanone to the expected (S)-4-phenyl-2-butanol using 5% v/v of
2-propanol as a cosubstrate. The ee increased exponentially with cosubstrate concentration, reaching
≥94% with 30-70% v/v 2-propanol. However, a decrease in enzyme activity was noticed at ≥30% v/v
2-propanol by a sharp drop in conversion. The lowest ee (<3%) was registered using 5% v/v 2-
propanol at 30-40 oC, which prolonged enzyme life that allowed reversible redox reaction with selectivity
mistakes to give the R-alcohol compared to ≥18% ee at 50-60 oC, where faster reaction rates
promoted selectivity mistake, but enzyme life was shortened by protein denaturation at the elevated
temperatures. Water-miscible and immiscible organic cosolvents (25% v/v) increased enzyme selectivity.
For methanol, ethanol, ethylene glycol and tert-butanol, the activity/conversion decreased with
an increase in pKa and log P while the stereoselectivity/ee increased.
Ritual Techniques in Affliction Rites and the Lutheran-Catholic ecumenical Liturgy of Lund, 2016
Authors: Belcher Kimberly Hope
Published: October 2022

Protest and reconciliation rituals play a contested but important role in social change. This essay analyzes how rituals of reconciliation effectively negotiate between competing factions and norms by using ritual techniques as embodied symbols. Against the horizon of theory from Victor and Edith Turner and Cas Wepener, participant observation of the Lutheran and Catholic Joint Commemoration of the Reformation “Common Prayer” in Lund, Sweden on October 31, 2016 reveals five stages: crisis/diagnosis, redress, forgiveness and acceptance, binding, and reparative mission. Each is marked by its own characteristic techniques, whereas some symbolic elements manifest the different stages throughout the liturgy. This liturgy demonstrates how one liturgy can speak to various factions and stages in the process of accommodating a new norm (Christian unity) within a contested set of identities (“Lutheran” and “Catholic”). It is in the stages of forgiveness and binding that the relationship between the ritual-symbolic realm and the real work of social reconciliation is most directly visualized.
Exploring the Eschaton. The Lord’s Supper as a Cultural Technique Enabling Prefigurative Politics
Authors: Smit Peter-Ben
Published: October 2022

Focusing on 1 Cor. 11, this article argues that the early Christian meal can be understood as a cultural technique that enables new knowledge and insight, specifically about the world to come. The argument takes its vantage point from an understanding of the early Christian meal as a form of social experimentation that engages in prefigurative practices, thereby anticipating the world to come. To explore the latter phenomenon, this article makes use of a body of theory concerning prefigurative politics, a field not commonly associated with the study of religion. However, it is shown that this body of theory is a useful tool for considering that the kind of knowledge regarding the world to come is made possible through the performance of the early Christian meal, understood as a cultural technique. In this manner, the present article aims to make contributions at the levels of both the theory regarding the study of the early Christian meal and insights into it.

(ZrO2)1-x-y(Sc2O3)x(Yb2O3)y solid solution crystals, where (x=0.07-0.09; y=0.01-0.03), were grown by directional crystallization of the melt in a cold crucible. It is shown that crystals with a cubic fluorite structure were obtained at a total concentration of stabilizing oxides Sc2O3 and Yb2O3 above 10 mol%. At a fixed concentration of Sc2O3, crystals with a total concentration of stabilizing oxides of 10 mol.%, which have the structure of a pseudocubic t''-phase, have the maximum conductivity. Crystals with a total concentration of stabilizing oxides of 10 mol, having a pseudocubic t''-phase structure, at a fixed concentration of Sc2O3, have the maximum conductivity. It is shown that an increase in the Yb2O3 concentration in the field of cubic solid solutions leads to a decrease in the conductivity of the crystals.

Published: October 2022

Using ab initio calculations, the stability issues of a series of Heusler alloys Ni2Mn1+xSb1-x (x=0, 0.25, 0.5, 0.75, 1) with staggered and layer-by-layer ordering of Mn atoms are investigated. It is shown that compositions with an excess of Mn are stable with respect to decomposition into constituent elements and unstable with respect to decomposition into a two-phase system consisting of a ferromagnetic cubic L21-phase Ni2MnSb and an antiferromagnetic tetragonal L10-phase NiMn. Thus, all nonstoichiometric compositions in the austenite and martensitic phases, taking into account different magnetic and atomic ordering, tend to segregate. Stability of alloys is possible only in stoichiometric compositions (x=0 and 1). Keywords: Heusler alloys, ab initio calculations, segregation, phase stability.

The structural and optical properties of colloidal Ag2S quantum dots in various environments are investigated. With the help of transmission electron microscopy, X-ray diffraction and energy-dispersive X-ray analysis the formation of colloidal Ag2S quantum dots with an average size of 2-3 nm with a monoclinic crystal lattice, and Ag2S/SiO2 core-shell systems based on them, has been established. The change in the luminescence quantum yield of quantum dots with the change of the surface environment state is shown. The decoration of TiO2 nanoparticles of 10-15 nm in size with Ag2S quantum dots was performed and the influence of the structure of the interfaces of quantum dots and their environment (2-mercaptopropionic acid, water, ethylene glycol, SiO2 dielectric shell with a thickness of 0.6 nm and 2.0 nm) on the formation of TiO2-Ag2S heterosystems was analyzed. For Ag2S quantum dots passivated with 2-mercaptopropionic acid, signs of charge phototransfer after adsorption on TiO2 nanoparticles surface have been established. Signs of reactive oxygen species appearance due to charge phototransfer in heterosystem are enstablished, based on methylene blue photobleaching under excitation of heterosystem outside of TiO2 fundamental absorption region, Keywords: Quantum dots, photocatalysis, luminescence, titanium dioxide, silver sulfide.

Published: October 2022

The effect of radiation defects on the critical current of a layered anisotropic superconductor has been investigated by numerical methods. Model defects simulating various cases of radiation damage to a superconductor as a result of electron and ion irradiation are considered. The obtained dependences of the critical current on the magnetic field show that the greatest pinning gain with equal irradiation fluence is given by defects forming 3D conical regions inside the superconductor. It is shown that in a weakly anisotropic superconductor, conical defects enhance the critical current more efficiently than in a strongly anisotropic one. The interaction of a vortex lattice with radiation defects is considered, vortex configurations arising under the action of the self-field of the transport current are obtained. Keywords: HTSC, pinning, Abrikosov vortices, radiation defects, Monte Carlo method.

Published: October 2022

An analysis of the field and time dependencies of the magnetization of PrDyFeCoB amorphous crystalline microwires is presented. It is found that the magnetization curve near the saturation field has a smoother approximation to saturation than in a ferromagnet, according to theoretical predictions for the spin-glass state of the alloy in the amorphous state within the framework of the random magnetic anisotropy model. Deviations of the dynamics of relaxation of the magnetization of microwires from the logarithmic time dependence and the disappearance of this difference when observing magnetic relaxation in a magnetic field are found. This indicates the typical dynamics of the magnetization reversal of a spin glass in a zero field and the ferromagnetic character of demagnetization in a nonzero field. The results indicate the presence in the PrDyFeCoB microwires of an exotic magnetic state of the material with stochastic local magnetic anisotropy. Keywords: spin glass, ferrimagnet, rare earth alloys, random magnetic anisotropy.

In order to clarify the possibility of sintering reactor powders of ultra-high molecular weight polyethylene under pressure at a temperature higher than its equilibrium melting point at atmospheric pressure (T0m) without catastrophic changes in the internal structure of particles, a comparative WAXS analysis was carried out of the samples sintered below (TT0m) this temperature and cooled under different conditions. A structural analysis of the X-ray scattering curves recorded in the Bragg-Brentano mode on a 2D Phaser Bruker diffractometer from UHMWPE reactor powders sintered under different conditions was carried out, and the crystallite sizes were calculated. It was found that an increase in the sintering temperature above T0m does not significantly change the crystal structure of the polymer, and the precursors produced can be used for further orientational hardening. Keywords: ultrahigh molecular weight polyethylene reactor powders, sintering, WAXS.

Authors: Butko A. V.  , Butko V. Y.  , Kumzerov Y. A.
Published: October 2022

Hybrid nanostructures with large interface between nanostructural elements play an important role in the modern electronics. Among these nanostructures are hybrid nanostructures formed at the interface of graphene with ensembles of molecular ions in the solution gated Graphene Field Effect Transistors (GFETs) that are promising for chemical and biological sensor fabrication. Therefore investigation of interfacial effects in electrical transport in these systems is interesting. This work is a theoretical study of dependence of the charge carrier mobility (μ) in these nanostructures on density of the interfacial molecular ions (Nii). We show that dependence μ propto 1/(Nii)1/2 obtained in free charge carrier model with short range scattering in case of the weak interaction between the charge carriers and the interfacial ions is in agreement with experimental transistor characteristics obtained at the high gate voltages. Keywords: graphene, hybrid nanostructures, transistors, mobility, interface.

Authors: Faiq Aseel Muhammad , Noori Midya Subhi
Published: October 2022

Social media platforms have become a favorable way of communication, sharing opinion and views about different topics around the world freely. Freedom of expression or free speech is the right to say whatever one likes; it has been sometimes conflated with hate speech. The latter is a public communication that expresses hate or advocates violence toward a person or group based on their race, religion or sex. The aim of the current study is to see the reactions of Kurdish and English commentators on similar political posts on Facebook platform, and what forms of hate speech were used more in each of them based on Bahador’s (2020) Intense Scale of Hate Speech model. After analyzing three similar posts, it has been concluded that the majority of the English commentators used negative character, while the majority of the Kurdish commentators used Dehumanization and Demonization, in which it was only found in one comment on the English posts.
Rough Set-Based Feature Selection for Predicting Diabetes Using Logistic Regression with Stochastic Gradient Decent Algorithm
Authors: Kaka-Khan Kanaan Mikael , Mahmud Hoger , Ali Aras Ahmed
Published: October 2022

Disease prediction and decision-making plays an important role in medical diagnosis. Research has shown that cost of disease prediction and diagnosis can be reduced by applying interdisciplinary approaches. Machine learning and data mining techniques in computer science are proven to have high potentials by interdisciplinary researchers in the field of disease prediction and diagnosis. In this research, a new approach is proposed to predict diabetes in patients. The approach utilizes stochastic gradient descent which is a machine learning technique to perform logistic regression on a dataset. The dataset is populated with eight original variables (features) collected from patients before being diagnosed with diabetes. The features are used as input values in the proposed approach to predict diabetes in the patients. To examine the effect of having the right variable in the process of making predictions, five variables are selected from the dataset based on rough set theory (RST). The proposed approach is applied again but this time on the selected features to predict diabetes in the patients. The results obtained from both applications have been documented and compared as part of the approach evaluations. The results show that the proposed approach improves the accuracy of predicting diabetes when RST is used to select variables for making the prediction. This paper contributes toward the ongoing efforts to find innovative ways to improve the prediction of diabetes in patients.
Extraction and Quantification of Words Representing Degrees of Diseases: Combining the Fuzzy C-Means Method and Gaussian Membership
Authors: Han Feng , Zhang ZiHeng , Zhang Hongjian , Nakaya Jun , Kudo Kohsuke , Ogasawara Katsuhiko
Published: October 2022

Background

Due to the development of medical data, a large amount of clinical data has been generated. These unstructured data contain substantial information. Extracting useful knowledge from this data and making scientific decisions for diagnosing and treating diseases have become increasingly necessary. Unstructured data, such as in the Marketplace for Medical Information in Intensive Care III (MIMIC-III) data set, contain several ambiguous words that demonstrate the subjectivity of doctors, such as descriptions of patient symptoms. These data could be used to further improve the accuracy of medical diagnostic system assessments. To the best of our knowledge, there is currently no method for extracting subjective words that express the extent of these symptoms (hereinafter, “degree words”).

Objective

Therefore, we propose using the fuzzy c-means (FCM) method and Gaussian membership to quantify the degree words in the clinical medical data set MIMIC-III.

Methods

First, we preprocessed the 381,091 radiology reports collected in MIMIC-III, and then we used the FCM method to extract degree words from unstructured text. Thereafter, we used the Gaussian membership method to quantify the extracted degree words, which transform the fuzzy words extracted from the medical text into computer-recognizable numbers.

Results

The results showed that the digitization of ambiguous words in medical texts is feasible. The words representing each degree of each disease had a range of corresponding values. Examples of membership medians were 2.971 (atelectasis), 3.121 (pneumonia), 2.899 (pneumothorax), 3.051 (pulmonary edema), and 2.435 (pulmonary embolus). Additionally, all extracted words contained the same subjective words (low, high, etc), which allows for an objective evaluation method. Furthermore, we will verify the specific impact of the quantification results of ambiguous words such as symptom words and degree words on the use of medical texts in subsequent studies. These same ambiguous words may be used as a new set of feature values to represent the disorders.

Conclusions

This study proposes an innovative method for handling subjective words. We used the FCM method to extract the subjective degree words in the English-interpreted report of the MIMIC-III and then used the Gaussian functions to quantify the subjective degree words. In this method, words containing subjectivity in unstructured texts can be automatically processed and transformed into numerical ranges by digital processing. It was concluded that the digitization of ambiguous words in medical texts is feasible.
Gambaran faktor lingkungan fisik wilayah kerawanan malaria di kabupaten buol
Authors: Ichsan Ichsan
Published: October 2022

Latar Belakang :Malaria adalah penyebab kematian nomor 4 di dunia setelah infeksi pernapasan, HIV/AIDS dan diare. Hasil laporan WHO dalam World Malaria Report tahun 2014 memberikan laporan bahwa terjadi 198 juta kasus malaria terjadi pada  97 negara yang ada di dunia dan dilaporkan 584.000 kematian terjadi setiap tahunnya. Malaria erat kaitannya dengan faktor–faktor lingkungan, seperti geofisik, biogeografik, klimatologik sampai pada faktor-faktor  yang berkaitan dengan agen penyebab penyakit, manusia dan  nyamuk vektornya. Perbedaan kondisi lingkungan di tiap wilayah menyebabkan penyebaran penyakit malaria pun berbeda. Kabupaten Buol merupakan salah satu daerah di Provinsi Sulawesi Tengah yang memiliki kasus kejadian malaria yang masih tinggi pada beberapa wilayahnya (API > 5/1000 penduduk). Kegiatan eliminasi dan pengawasan malaria secara terestial dalam wilayah yang luas membutuhkan banyak biaya, tenaga dan waktu. Pengaruh subjektifitas dalam hasil pengawasan merupakan masalah lain pada aplikasi metode konvensional dari pengawasan vektor dan penyakit yang umumnya bersifat manual. Masalah teknis ini perlu diatasi dengan metode atau alat alternatif yang objektif, efisien dan efektif baik dalam pemetaan, pemantauan/monitoring maupun prediksi untuk wilayah rawan malaria.

Published: October 2022

In the past thirty years, French teaching in Chinese universities has undergone many changes. Language plays a vital role in transmitting information between countries. Grammar teaching should be an important part of foreign language teaching. Of course, Chinese students’ learning habits should be respected. However, investigating their preferred learning style in the process of contextualization is our responsibility as well. Therefore, in order to meet the new requirements of grammar teaching in China, we must combine the role and communicative function in grammar teaching. Finally, based on the results of the analysis, the corresponding teaching suggestions are summarized.

El sistema de inmunidad adaptativa en bacterias y arqueas, encargado de reconocer las secuencias de DNA invasores, se caracteriza por tener grupos de secuencias palindrómicas cortas repetidas e intercaladas de manera regular por espaciadores (CRISPR). Las proteínas asociadas a CRISPR (Cas) y los RNAs guías complementarios a secuencias específicas del DNA blanco constituyen una de las herramientas de edición genética más utilizadas para modificar a los organismos. En los últimos años se ha incrementado la variedad de los sistemas CRISPR/Cas, adaptándose a microorganismos como las levaduras, que cuentan con potencial biotecnológico. El objetivo de esta revisión es facilitar la comprensión de los conceptos básicos del sistema CRISPR/Cas9 y reconocer algunas de las variedades de esta herramienta molecular que se han implementado de manera exitosa en distintas levaduras. Asimismo, se describen varias de las nuevas tecnologías basadas en CRISPR que están revolucionando la investigación.

El artículo tiene como objetivo identificar y analizar la producción de libros académicos en Colombia entre 2013 y 2019. Para hacerlo, toma como fuente la base de datos de ISBN gestionada por la Cámara Colombiana del Libro y selecciona dentro del universo editorial general, a través de materias, la producción propiamente académica. Así, con la información exigida por la organización gremial del libro en el país y suministrada por los mismos editores, se presentan criterios que permiten caracterizar la producción de libros académicos en Colombia dentro del periodo  Es la primera caracterización de este tipo que se hace en el país. Resulta llamativo que, según la metodología utilizada, el grupo de libros académicos constituya el 67% de la producción total de libros registrada. Las materias en las que más se publican libros académicos son Sociología con el 15%, Economía con el 12% y Derecho con el 10%. Con respecto al origen de las publicaciones, se debe reconocer el papel fundamental que juegan las editoriales universitarias. El grupo de libros académicos es además analizado por si se trata o no de traducciones. Este aporte es el piloto para consolidar los criterios para hacer posibles estudios comparados de la producción de libros académicos en países de habla española y portuguesa.

Abstract: The development of biologically synthesised nanoparticles using plant extracts plays an important role in the field of nanotechnology as it is eco-friendly and does not involve any harmful chemicals. The present study deals with green synthesis and characterization of Copper oxide and Iron oxide nanoparticles using Hymenocallis littoralis floral extract. To our knowledge, this is the first report where this flower extract was found to be a potential source for the green synthesis of copper oxide and iron oxide nanoparticles. Aqueous floral extract of fresh flowers of Hymenocallis littoralis were utilised for the synthesis of nanoparticles. The aqueous extract acts as both reducing and capping agent. The synthesised oxide nanoparticles of copper (CuONPs) and iron (IONPs) were confirmed by the change of colour after addition of floral extract into the precursors CuSO4.5H2O and FeCl3.6H2O salt solutions separately. The synthesised nanoparticles were characterised by UV-Visible Spectroscopy and Scanning Electron Microscopy(SEM). The UV-VIS spectroscopy showed the absorption peaks at 300nm and 314nm for CuONPs and IONPs respectively. The SEM analysis confirmed the presence of CuONPs and IONPs nanoparticles and the average size of some selected particles ranged from 100nm-200nm. It was observed that the aqueous floral extract can reduce copper and iron ions into their oxide nanoparticles within a day. Following the synthesis and characterization, the antimicrobial activity of the nanoparticles was evaluated. Thus, the method followed has the potential for simple, safe and stable biosynthesis of these nanoparticles.

Published: October 2022

Uma das doenças a que o feijão está mais vulnerável é a do Mosaico Dourado, provocada por geminivírus que têm como vetor a mosca branca. Essa doença tem provocado danos e perdas significativas à cultura do feijoeiro-comum. A Embrapa desenvolveu o evento transgênico Embrapa 5.1, que proporciona Resistência ao Mosaico Dourado (RMD). Tal tecnologia contribui para o aumento da produtividade e redução dos custos para os agricultores. O objetivo do presente trabalho foi analisar o posicionamento dos produtores de feijão-comum quanto à adoção da tecnologia, além de identificar o perfil do produtor e da propriedade, forma de gestão e perfil tecnológico. É uma pesquisa quali-quantitativa, com caráter exploratório e descritivo, utilizando-se da pesquisa bibliográfica, documental e levantamento de campo. Para o levantamento dos dados fez-se uso de questionário eletrônico e ligações telefônicas direcionadas aos produtores. Os dados coletados foram analisados utilizando-se tabelas de frequência e gráficos para variáveis qualitativas, e os dados quantitativos foram tratados pelo programa estatístico R. O resultado indica que a maioria dos participantes é favorável à tecnologia RMD e que a adotaria, sendo o principal incentivo a redução do uso de pesticidas e o menor risco de perda da produção.

Published: October 2022

Objectives: The aim of this study is to evaluate the GLUT-1 expression in benign proliferative, hyperplastic, and malignant endometrial tissues, to evaluate the usefulness of GLUT-1 expression in endometrial hyperplasia, and to determine its role in the neoplastic progression to endometrioid type adenocarcinoma. We also aimed to analyze some prognostic clinical parameters (age, stage, grade).

Methods: This cross sectional study was carried out on paraffin embedded surgical specimens of endometrial tissue. Applying the immune histochemical techniques by using the GLUT-1 as a primary antibody, statistical analysis was done and the correlation with different clinical and pathological parameters were assessed.

Results: 98 cases of endomertial tissue, 17.4% disordered proliferative endometrium, 22.4% endometrial hyperplasia without atypia, 18.4% endometrial hyperplasia with atypia, 41.8% endometrioid adenocarcinoma, 56.1% were GLUT-1 positive. Significant correlation was found between GLUT-1 expression and increasing degree of atypia as it was negative in benign proliferative and hyperplasia without atypia meanwhile positive in hyperplasia with atypia and endometrioid carcinoma. Significant correlation with grade of carcinoma, patient age, no correlation was found with ovarian and cervical metastasis, no significant correlation was found with tumor stage.

Conclusions: GLUT-1 immunostaining may be useful in distinguishing hyperplasia without atypia from hyperplasia with atypia; GLUT-1 overexpression is a consistent feature of endometrioid adenocarcinoma.

Authors: Layth Zina Adnan , Yaseen Zainab Sami
Published: October 2022

Objectives: This study aimed to evaluate the role of MRI in differentiation between benign and malignant well-circumscribed breast masses.

Methods: A prospective cross-sectional study conducted on selected female patients with Breast mass who their age older than 35 years. All patients underwent examination using 1.5 Tesla magnetic resonance unit (MAGNETOM AERA, SIMENS).

Results: 30 female patients were selected (mean age of 44.2±9.2 years, range between 35-69). Final findings of MRI revealed that 6 (20%) women had malignant breast mass while 24 (80%) women had benign breast mass. The histopathology revealed that 4 (13.3%) women were having malignancy while 26 (86.6%) were having benign breast tumor. There was a highly significant association between malignancy and hyperdense mammography findings of women (p<0.001), multiple lymph nodes for women (p<0.001), increased size of mass by MRI (p<0.001), circumscribed macrolabular lesion on MRI, rapid early kinetic phase of enhanced MRI (p<0.001), washout late kinetic phase enhanced MRI (p<0.001), and MRI kinetic curve type 3(p<0.001). There was a highly significant association between homogenous enhanced MRI findings of women and benign lesions (p<0.001).

Conclusion: The validity results of MRI in differentiation between benign and malignant circumscribed breast masses are high, except for positive predictive value, and application of kinetic curve dynamic contrast enhancement increases magnetic resonance in differentiation between benign and malignant circumscribed breast masses.
