La glomerulonefritis membranoproliferativa es una lesión poco frecuente, que abarca un grupo de patologías que comparten un patrón histológico en común, y pueden originarse a partir de diversos mecanismos patogénicos. Con base a los hallazgos de la biopsia renal, inicia un proceso que busca determinar la etiología de la lesión. El daño renal inicial ocurre por el depósito de inmunoglobulinas, elementos del complemento o ambos en el mesangio y en el endotelio capilar, generando depósitos subendoteliales, subepiteliales, y/o en la membrana basal glomerular, adoptando con frecuencia el glomérulo un aspecto lobulado.  Se presenta el caso de un hombre de 48 años que ingresó al servicio de urgencias del Hospital San José de Bogotá, sin antecedentes relevantes que debuta con proteinuria en rango nefrótico severo (62 gramos en 24 horas), elevación de nitrogenados y reporte de biopsia con glomerulonefritis membranoproliferativa, se describe el enfoque clínico y diagnóstico de esta entidad.

Authors: Mendoza Panta Diego Alexander , Cuesta Mero Paola Lisette , Correa Mejía Jimmy Patricio
Published: December 2020

El síndrome hemolítico urémico (SHU) es una entidad clínica deﬁnida por la tríada anemia hemolítica no inmune, trombocitopenia e insuﬁciencia renal aguda, en la que las lesiones subyacentes están mediadas por un proceso de microangiopatía trombótica (MAT) sistémico. Distintas causas pueden desencadenar el proceso de MAT que caracteriza el SHU.

Se describe el caso de una mujer, con antecedentes de Diabetes Mellitus, Hipertensión arterial, quién ingiere veneno de serpiente tipo Bothrops con fines medicinales; luego de 72 horas es hospitalizada por edema de miembros inferiores, dolor abdominal, equimosis, ictericia, realizándose analítica sanguínea donde se constata trombocitopenia, elevación de azoados y anemia, documentándose datos de Falla Renal Aguda, catalogándose como Síndrome hemolítico urémico secundario a la ingesta de veneno de serpiente. Se describen aspectos del diagnóstico, manejo clínico que se realizó. El compromiso renal por veneno de serpiente Bothrops es una entidad poco frecuente, que si no se maneja de manera adecuada puede ser letal, y más aún si existen comorbilidades predisponentes.

Background: Alterations in the acid-base balance are studied in all medical specialties. Although most cases derive from a preexisting pathology, they can also manifest themselves in a primary context. The proper identification of the acid-base disorder allows the pathological process to be characterized. The correct interpretation of the blood gasometry as a technique for monitoring the ventilatory status, oxygenation and acid-base balance of a patient requires the integration of various physicochemical approaches in order to specify a diagnosis, quantify a therapeutic response, and monitor the severity or the progression of a pathological process.

Material & Method: A literature review was conducted in the PubMed, Scopus and Science Direct databases. The articles were selected according to the title and the abstract and sorted by topics relevant by pathophysiology, divergences, clinical approach, diagnosis, and management.

Results: A guide the clinical correlation of the critical patient with the blood gasometry parameters to characterize the acid-base disorder through the proposition of a diagnostic algorithm.

Conclusion: The incorporation of the three theories in a diagnostic algorithm facilitates a greater understanding of the pathophysiological mechanisms and allows us to identify a more precise therapeutic objective to correct the underlying disorder in the different clinical contexts of the patient.

Published: December 2020

Research objectives: To study the migration of the serving Tatars of Meschera and their economic development of the “wild field” in the southern Cis-Volga region’s “Hill Bank Land” in the context of the military confrontation with the Nogais at the end of the sixteenth and beginning of the seventeenth centuries. Research materials: Bibliographic and archival materials about the military border service of the Meshchera Tatars and their colonization of the territory of the former Nogai nomads in the Volga region. Results and novelty of the research: The authors studied the military confrontation bet­ween the serving Tatars of the Arzamas and Alatyr districts and the Nogai detachments at the end of the sixteenth and beginning of the seventeenth centuries. This process became the reason for the resettlement of large groups of Tatars on the territory of the Volga region. The serving Tatars of Meschera began to populate lands on a massive scale in the southern Cis-Volga region after their military clashes with the Nogais in 1571, 1577, 1581, 1593–1594, 1612, 1614, 1620, and after the construction of the city of Simbirsk and the Karsun-Simbirsk defensive line. Today, these territories include the Drozhzhanovsky, Buinsky, Tetyushsky districts, and part of the Kaibitsky district in the Republic of Tatarstan. An important historical event in this process was the defeat of the Nogais in 1612 by the serving Alatyr Tatars and Mordovians under the leadership of Bayush Rozgildeev and Yamash Mangushev. It was during this period that the serving Tatars began to receive estates in the “Dikoe pole” (”Wild field”). The settlement of the region called “Gornaya storona” (“Hill Bank Land”) by serving Tatars continued during the seventeenth and first half of eighteenth century. At this time, there was a shift in the social status of the serving Tatars that was associated with their transfer to the department of the Kazan Admiralty. This was called the Lashman Service. Due to the economic activity of the Tatar landowners, the southern Cis-Volga region became a developed agricultural region in the eighteenth and nineteenth centuries, with a wide cooperative peasant trade and the establishment of various crafts. In conclusion, the military border campaign against the Nogais and other nomads in which the Meschera Tatars participated was a powerful stimulus for the formation of one of the key ethnocultural centers of the Tatar people.
Demographic potential of the Russian Far East: expectation and reality

Published: December 2020

For almost three decades, the problem of the annual decline in the demographic potential of the Russian Far East has not lost its relevance. Joining the list of Russia's national priorities in the 21st century and the active state policy pursued in this regard for the accelerated development of the largest macro-region in the country did not lead to positive changes in the demographic trend. Despite different kinds of preferences for the potential Far-Easterners, their number does not cover the number of people leaving the Far East. The article analyzes the indicators characterizing the change in the demographic potential of the Far-Eastern federal district in the context of the constituent entities of the Russian Federation for a five-year period of an active policy of socio-economic development of the macro-region. The main components of natural movement of the population are considered. It is shown that the Russian Far East is characterized by the all-Russian tendency of a decline in the birth rate, caused by the deformation of the age composition of the population, primarily women of fertile age, changes in the intensity of fertility and its age profile. While comparable to the all-Russian general coefficient, the Far East is characterized by an increased mortality rate among the population of working age. Moreover, during the analyzed period, the gap between the average Russian and Far-Eastern mortality rate of the working-age population is growing for most causes of mortality. The high mortality rate of the working-age population is the main factor in the low life expectancy of the Far East. Comparison of real and predicted estimates of demographic potential established in the Concept of demographic policy of the Far East and the Decrees of the President of the Russian Federation is carried out. As a result, it was found that expectations of the future demographic potential of the Far East laid down in the documents significantly exceed the real demographic capabilities of macro-region and will most likely remain unrealizable.

E DAÍ?

Published: December 2020

Diante de toda a surrealidade imposta pelo ano de 2020, senti que era o momento de desabafar um pouco em forma de charge. A pandemia afeta a todos de formas diferentes. O meu caso, em específico, como autor de Histórias em Quadrinhos e Ilustrador, o chamado “home office” não é algo estranho e nem fora da rotina. Mas os meses foram passando...A postura irresponsável do então ocupante do cargo máximo do poder executivo brasileiro, traduzida em um “E DAÍ?”, diante da constatação de mais de oito mil mortes (naquele momento), mesmo perante o caos e o colapso da saúde pública do país, foi o estopim para esta pintura.Devo confessar que a ideia não foi original. Diversos amigos Caricaturistas e Chargistas já haviam representado o presidente e sua total falta de empatia diante das mortes, mas eu senti que também precisava fazer. e, no momento, me senti bem. A charge não precisa necessariamente trazer o riso, e, riso nem sempre é algo leve. O humor pode ser simplesmente a nossa incredulidade de fronte aos absurdos. O que fica é o meu repúdio e um questionamento:como poderemos lidar com tantos despropósitos e todos agirmos de maneira responsável e cidadã, buscando passar por esta crise, sem este custo absurdo de perdas de vidas?

Objetivo: Esta pesquisa teve como objetivo investigar a percepção subjetiva de saúde de idosos, participantes de um programa de inclusão digital, no projeto Viver a Vida da Paranaprevidência. Metodologia: Fizeram parte da pesquisa 21 idosos com idade igual ou superior a 60 anos, que participaram de uma intervenção de inclusão digital no programa Viver a Vida, o qual foi criado a partir da parceria entre PARANAPREVIDÊNCIA e a Secretaria de Estado da Administração e Previdência e o Governo do Paraná. Para avaliar a percepção de saúde foi feita uma pergunta “O que é ter saúde para você?” A análise dos dados descritivos foi realizada por meio de média, desvio padrão e frequência. A análise de dados qualitativos foi feita por meio de análise temática, sendo realizada uma análise da coocorrência das palavras significativas. Na sequência da metodologia, foi aplicada uma técnica de identificação de temas chamada nuvem de palavras, utilizando o software IRaMuTeQ (Interface de R pour les analyses multidimensionnelles de textes et de questionnaires). Resultados: A nuvem de palavras, deixa claro que, na perspectiva das participantes, saúde é vida, saúde é viver bem, saúde é não ser dependente de outras pessoas e ter autonomia nas suas escolhas, não tomar medicamento, comer com qualidade, ter bom relacionamento com os outros e consigo mesmo, levando a um bem-estar físico e emocional. Conclusão: Verifica-se que o termo saúde estabelece relações com o bem-estar, emocional, viver, mental, cuidar, funcionar, comer, doença, sentir e corpo, levando a crer que a percepção de saúde para as participantes envolve todos esses fatores e não está relacionado apenas a ausência de doença.

Published: December 2020

Through collaborative media arts practice we explore texture morphing soft robotics as an artistic medium of expression. We present an installation, Homo Viridis, that features a soft robotic interface developed to mediate signals between a vascular plant and a human body. The exposition paper discusses how Homo Viridis stages a situation of hybridity where individual, more-than-human subjectivities are mentally and physically intertwined. In conclusion, the paper reflects on how connecting organisms through soft robotic interfaces can actualize visions of a novel being - a ‘posthuman entity’. We argue that such a being might be physically composed of organic and synthetic elements that come together, but that it can also exist as a conceptual persona that may initiate discussions on what humans can become.
Immune targeted therapies for COVID-19 Infection: A Promising Outlook
Authors: Forouzani-Haghighi Bahareh , Rezvani Alireza , Vazin Afsaneh
Published: December 2020

In December 2019, the coronavirus disease-19 (COVID-19) outbreak emerged
in Wuhan, China. On March 11, 2020, the WHO (World Health Organization)
officially declared it a pandemic. Reports indicated that the associated
mortality of the infection is quite higher in the elderly, patients with
specific comorbidities (like diabetes mellitus), and generally the ones
with a compromised immune system. A cohort study of 452 patients with
laboratory-confirmed COVID-19 in Wuhan, China, reported a dysregulated
immune response in these patients. As a result of this suppressed immune
response, the increase of neutrophil to lymphocyte ratio (NLR), T
lymphopenia, and decrease of CD4+ T cells was considered as common
laboratory findings, especially in severe cases. On the other hand,
there is also clear evidence of T cell exhaustion in severely ill
patients. So, the immune system seems to play an important role in
disease prognosis and pathogenesis. This study aims to review the
evidence on the immune response dysregulation in COVID-19 infection and
the potential role of immunoregulatory treatments such as immune
checkpoint inhibitors, interferons, and CD200 inhibitors in altering
disease prognosis, especially in critically ill patients.
Prognostic Significance of COX-2 Expression in Wilms' Tumor
Authors: Ceylan Onur , Caglar Ozgur
Published: December 2020

Objectives: In Wilms Tumor (WT) secondary malignancies caused by the
side effects of intensive treatments remain one of the important
problems. Therefore, there is a need for new studies to identify low-
and high-risk groups for WT and to improve the treatment regimens of
children in the low-risk group. Therefore, in our study, we aimed to
determine the prognostic significance of the cyclooxygenase-2 (COX-2)
biomarker in WT. Materials and Methods: Our study included 24 patients
diagnosed with WT between January 2010 and December 2019. The
correlation between COX-2 expression and significant prognostic
parameters was investigated by studying COX-2 antibody using the
immunohistochemical method. Results: COX-2 expression was observed in 22
of the patients, and the expression was more evident especially in the
epithelial component. There was no significant correlation between COX-2
positivity and prognostic parameters. Conclusions: In our study, no
significant relationship was found between significant prognostic
parameters and COX-2 expression. We think that the COX-2 pathway is
effective during the development phase of WT, since COX-2 expression was
observed in almost all patients, therefore it may be beneficial to add
COX-2 inhibitors to the treatment, and that a sufficient number of
studies should be conducted in this respect.

Mitral annular disjunction (MAD) is a structural abnormality of the
mitral annulus, defined by a detachment of the atrial wall-mitral
valvular junction from the left ventricular (LV) free wall. This
structural abnormality in mitral annulus fibrosus is significantly
associated with the presence of mitral valve prolapse (MVP) [1], but
it can be also detected in normal cases as an anatomical variation of
the mitral annulus fibrosus [2]. The main tools to detect MAD are
echocardiography and cardiac magnetic resonance. Prevalence of MAD in
the general population ranges from 7% [1] to 9% [2]. Several
studies proved an association between MAD and arrhythmic events,
independently of concomitant mitral valve abnormalities, suggesting the
existence of a novel entity: MAD arrhythmic syndrome [3]. Herein we
describe a case report of a middle age man with MAD who experienced
ventricular arrhythmias and placement of an implantable
cardioverter-defibrillator (ICD).
The US banking system: Does the size of the institution matter to its economic-financial situation?
Authors: Fernández Fernández , Vázquez Virginia , Vicente Virseda
Published: December 2020

This paper analyzes the relationship between the size of the entities in the US banking system and their economic-financial situation. The objective of this study is to group different economic and financial variables of the entities together into factors that characterize the US banking system and identify how the factors vary according to the size of the entities. To do this, we start from the values taken by 32 economic-financial and regulatory ratios, obtained directly from the Federal Deposit Insurance Corporation (FDIC), for a period between the first quarter of 1990 and the penultimate of 2016. With this data it is performed a factorial analysis that allows synthesizing the 32 variables in 7 factors and, at the same time, obtaining relationships between these variables and the size and between themselves. Finally, through a neural network, the previous factors are hierarchized according to the influence that the size of the entities exerts on them. Among the conclusions reached, it should be noted that the loan structure is the factor that best classifies the size. It also determines the existence of a negative ?profitability solvency? relationship with larger entities, (Assets > $250 B.) and smaller ones (Assets < $100 M.), as well as demonstrating the existence of moral hazard and the need for regulation that limits said risk (because the largest entities are the least solvent and assume the most risks).
Comparison of the structural and photo-catalytic properties of nanostructured Fe3O4/TiO2 core-shell composites synthesized by ultrasonic and Stöber methods
Authors: Parast Faezeh , Montazeri-Pour Mehdi , Rajabi Masoud , Bavarsiha Fatemeh
Published: December 2020

In the present research, Fe3O4/TiO2 magnetic photo-catalytic nanocomposites
with a core/shell structure were successfully synthesized using two
techniques of ultrasonic and St?ber. In this way, iron oxide (II, III)
nanoparticles as soft magnetic cores of this composite were prepared by
utilizing a chemical method assisted by ultrasound with a Fe+3/Fe+2 molar
ratio of 1.5 under the nitrogen atmosphere. Thereafter, titanium oxide
coating was performed on Fe3O4 nanoparticles by using tetrabutyl
orthotitanate (TBOT) and titanium isopropoxide (TTIP) precursors. The
resultant nanostructures were characterized by means of X-ray powder
diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, energy
dispersive X-ray (EDX) analysis, vibrating sample magnetometer (VSM),
scanning electron microscopy (SEM), and transmission electron microscopy
(TEM). Through findings obtained from TEM examinations, the formation of
core/shell nanostructure was confirmed in the prepared Fe3O4/TiO2
composites. Analysis of magnetic properties revealed that titanium oxide
coating on iron oxide nanoparticles reduces saturation magnetization (Ms).
The values of saturation magnetization for Fe3O4 powder and Fe3O4/TiO2
nanocomposite powders achieved via ultrasonic and St?ber methods were 60, 23
and 9 emu/g, respectively. Photo-catalytic properties of Fe3O4/TiO2
nanostructures were evaluated by the use of methylene blue dye under UV
light. Results indicated that Fe3O4/TiO2 composite obtained by the St?ber
method has a better photo-catalytic property as well as a decreased but
acceptable magnetic separation. Degradation of methylene blue dye in the
presence of photo-catalytic powder prepared by ultrasonic and St?ber
procedures was 61 and 69 %, respectively, within 90 minutes of UV light
exposure.

treatment (2 h at 480?C), and aging processes (3, 6, 9, and 12 h,
respectively, at 120?C) were applied to the samples. The hardness and
tribo-metallurgy properties of the products were investigated. After
sintering, the hardness values of the three alloys were close to each other;
however, the solution treatment after sintering caused the hardness values
to increase significantly. It was determined that the Al-2Zn-5Cu-4Mg alloy
had the highest hardness increase with the 6-h aging heat treatment. The
wear resistance of the materials in all the compositions had increased. The
highest wear resistance and lowest friction coefficient were obtained for
the Al-2Zn-5Cu-4Mg alloy with the 6-h aging heat treatment.

This paper covers the creation and numerical realization of proposed mathematical model of hydrodynamical processes in shallow water based on contemporary information technology and new computational methods that allow improve the prediction accuracy of the environmental situation using the example of the Taganrog Bay in the Azov Sea basin. The proposed mathematical hydrodynamics model takes into account surges, dynamically reconstructed geometry, elevation of the level and coastline, wind currents and friction against the bottom, Coriolis force, turbulent exchange, evaporation, river flow, deviation of the pressure field value from the hydrostatic approximation, the salinity and temperature impact. The discretization of the mathematical model of hydrodynamics was performed using the splitting schemes for physical processes. The constructed discrete analogs possess the properties of conservatism, stability, and convergence. Numerical algorithms are also proposed for solving the arising SLAEs that improve the accuracy of predictive modeling. The practical significance of this research is software implementation of the developed model and the determination of limits and prospects of its application. The experimental software development was based on a graphics accelerator for mathematical simulation the possible scenarios of shallow water ecosystems in consideration the environmental factors influence. The decomposition methods taking into account the CUDA architecture specifications were used at parallel implementation for computationally labors diffusion-convection problems.

Islam must be able to exist in all situations and conditions, Al Qur'an as the main source is expected to have its existence especially in facilitating the benefit of Muslims. Because the benefit and needs of one community to another have differences, then the need for the concept of abrogation becomes one of the media and methods in weighing a benefit that implies the emergence of relevant new laws to be applied. This paper tries to unravel the basic concepts of abrogation (Naskh) and the domain of its work in the area of Islamic jurisprudence. with descriptive-analytical study, the result is that the concept of abrogation must indeed exist in the minds of every mujtahid in formulating a legal solution.

This article discusses Muslim convertsâ€™ (muallaf) reception on Q.S. al-Muâ€™minÅ«n (23): 1-11 as a process of self-understanding to become a Muslim and looks for the factors prompting their reception. This article is based on field research on the community of Muslim converts affiliated with the Mualaf Center Solo (MCS). This research employed the theory of Qurâ€™anic reception. The collected data is examined using discourse analysis and then presented descriptively. The research shows that Muslim converts in MSC are capable of comprehending Q.S. al-Muâ€™minÅ«n (23): 1-11 and of understanding the characters of Muslims described in these verses such as pious, generous, honest, self-discipline, social care, reproduction health awareness, trustworthy, responsible and steady. The Muslim converts, however, have different reception on those verses which was influenced by certain factors, among others are religious motivation, the role of family, social interaction, and self-awareness.

Published: December 2020

The Algerian English foreign language (EFL) baccalaureate is a high stake exam that assesses both students’ learning and their critical thinking skills. Thus, devising appropriate and effective exam questions may be a problematic issue for tests designers. Under the requirements of the current Algerian English curriculum, the exam questions must cover the lower and higher-order thinking skills of Bloom’s taxonomy. On this basis, this research paper seeks to investigate the effectiveness of the EFL baccalaureate exam papers, and aims to answer the research question: ‘To what extent does the Algerian EFL Baccalaureate exam paper cover the lower and higher-order thinking skills of Bloom’s taxonomy?’ This research is a descriptive content analysis; the researcher analyzed the exam questions of the Algerian EFL Baccalaureate under the cognitive domains of Bloom’s taxonomy. This study is significant as it helps tests’ designers to design practical EFL exams that develop students’ thinking skills and language competencies. The findings of this study revealed that the EFL baccalaureate exam does not establish the students’ higher-order thinking skills and does not assess their communicative abilities. Accordingly, some recommendations are suggested to hopefully help test designers to improve the quality of the EFL Baccalaureate questions.

Svako ko je selio domaćinstvo bar jednom u toku života, zna koliki stres selidba može da prouzrokuje, jer se stres ne odnosi samo na selidbu domaćinstvao, nego i na kreiranju nove životne rutine i novog životnog prostora. Zato je stres od selidbe prema naučnim istraživanjima pozicioniran na 5. mestu najstresnijih događaja u životu.

Ako se napravi analogija sa selidbom fabrike, ona bi zauzela sigurno visoko mesto među najstresnijim poslovnim iskušenjima, koji vlasnici fabrike i učesnici u selidbi, mogu u toku svoje karijere da dožive. Jer u toku procesa selidbe domaćinstva, čovek paralelno nastavlja sa svojim životnim obavezama, dok u slučaju selidbe fabrike, fabrika staje sa radom i u tom periodu dolazi do pozpunoh zaustavljanja generisanje kapitala. Šta više, proces selidbe troši finansijske resurse sve više i više kako vreme teče.

Selidba fabrike je veće kompleksnosti od izgradnje nove fabrike i potrebno joj je pristupiti sa posebnom brigom uzimajući u vide različite aspekte procesa selidbe. Posebno treba biti vođena briga o istrošenim delovima fabrike u toku celog procesa selidbe, zato štosu  istrošeni delovi fabrike, čija je jačina i krutost u toku vremena oslabljena, podložniji oštećenju i lomu i čine proces selidbe samo po sebi još težim.

Dental implant applications for edentulous jaws are today considered a predictable, safe, and daily technique for giving patients new aesthetics and function. However, the success of the implant therapy should be thoroughly investigated for long-term clinical results about the stress distribution in hosting bone tissue and prosthetic components. In this study, the effect of different prosthesis designs on the stress distribution around the abutment and dental implant in bone tissue was investigated using the finite element method (FEM) with Workbench module of the ANSYS package program. The examination focuses on the effect of the number of implants in teeth layouts on the distribution of stresses, strains, and displacements. In the study the historical development of dental implant problems is mentioned, and some previous studies are summarized. Critical information is also given about biomechanics, dental implants, jawbone, teeth, and the finite element method. Totally four different cases, one layout with three implants and three layouts with two implants, were analyzed. Titanium was used as an implant and abutment material. Nobel Active implants and abutments manufactured by Nobel BioCare Company were used for complete toothless lower jaw case. The critical stress, strain, and displacement values were determined for all four different scenarios. As a result, it was concluded that stresses, strains, and displacements have lower values for the design of triple dental implants compared to other layouts.
