Published: June 2022

Background and objectives: Several infection are associated with abortion among them toxoplasmosis and cytomegalovirus infection. Toxoplasma gondii causes congenital toxoplasmosis along with HCMV a highly teratogenic virus that interfere emberyogenesis. Both infections are almost asymptomatic thus, diagnosis depends primarily on serological tests namely ELISA to detect antibodies in serum of pregnant women. Methods: A semi-quantitative Elisa technique is applied for detection of anti-toxoplasma IgG and anti-CMV IgM in sera of 348 pregnant women tested in Rezan Private Lab who have previously experienced abortion. Results: The seropositivity rates are 29.05% for Toxoplasma-IgG and 45.25% for CMV-IgM. The increasing age is associated with increasing times of abortion (p ≤ 0.0001). Cases with co-infection are more likely to have multiple abortions. The number of abortions is statistically not highly associated with socioeconomic status of pregnant women (p ≥ 0. 1364). Conclusion: Through this study a plain connection can be figured out between chance of multiple times of abortion and infections caused by CMV and Toxoplasma gondii. Similarly, this association is verified more with increasing age while the socioeconomic status of cases is not indicative for the possibility of multiple miscarriages. All these results are rationally expected and in agreement with most other studies.

Authors: Zangana Kawes , Chalabi Dlair
Published: June 2022

Background and objectives: Acute lower respiratory tract infections (ALRI) are the leading cause of morbidity and mortality among children in developing countries. Pulse oxymetry is a simple technique to determine the oxygen saturation. However, the detection of hypoxemia by use of pulse oxymetry is not available in most situations in developing countries; in addition, the availability of supplementary oxygen is inadequate. It is therefore, important to identify hypoxemia accurately in children by using of clinical signs. The objective of this study was to find out the clinical signs and symptoms that predict hypoxemia in acute lower respiratory tract infection. Methods: A well matched case control study was performed on 120 children from 2 months to 5 years of age admitted with acute lower respiratory tract infections (ALRI) to the emergency department of Raparin Pediatric Teaching Hospital -Erbil, from 1st January 2009 to 1st April 2010.Clinical symptoms and signs were recorded .Hypoxemia was defined as oxygen saturation less than 95%. A portable oxymeter was used to measure oxygen saturation with an appropriately sized sensor on the finger or the toe. The reading was taken while the child was breathing room air. The clinical symptoms and signs to predict the presence of hypoxemia were evaluated. Results: Sixty (50%) children were hypoxemic. The median O2 saturation was 91.2%with a range of 72-93.8%. Physical signs including intercostal and subtotal retractions, supraclavicular recessions, grunting, nasal flaring, cyanosis, head nodding, were statistically associated with hypoxemia. Conclusion: None of the clinical features either alone or in combinations has sufficient sensitively and specificity to predict hypoxemia in children with acute lower respiratory tract infections, therefore pulse oxymetry is desirable for identification of hypoxemia.

A Primer into the Current State of Artificial Intelligence in Gastroenterology
Authors: Moldoveanu Alexandru Constantin , Fierbinteanu-Braticevici Carmen
Published: June 2022

Artificial intelligence (AI) is not a new idea or field of research. However, recent advancements in computing technology as well as increasing worldwide experience in applying AI to various fields have enabled us to hope that applying it to the medical practice could improve outcomes. The aim of the article was to evaluate potential applications of artificial intelligence (AI) in the clinical practice of gastroenterology. AI algorithms can offer many benefits over the traditional diagnostic, prognostic, therapeutic scores, or non-AI enhanced procedures that we perform today. It can very easily process complex mathematical data, which would allow to account for many parameters and with highly sophisticated formulas to determine a conclusion, to a degree that would be impractical or impossible for a human to do alone in the clinical practice. This could allow for significantly more individualized treatments for each patient. As more data becomes available, it can be fed into the algorithm, which allows it to change based on the new data. However, we must be aware that most studies performed today are still early retrospective studies, and their utility still needs to be evaluated in future large scale prospective studies. Apart from the medical challenges, it must be noted that the impact of large-scale implementation of artificial intelligence will have challenges related to ethical and financial aspects as well.

Published: June 2022

Crohn’s disease and ulcerative colitis, the two most common inflammatory bowel diseases (IBD), arecharacterized by chronic relapsing inflammation. Although recent progress regarding the therapeutic approachto these diseases has been made in the development of biologic therapies, not every patient responds well,resulting in a high percentage of ineffectiveness. Even though the immunological cascades range between thecurrent pharmacological agents for IBD treatment and the constant research for more possible pharmacologicaltargets, a lot of progress still needs to be made regarding the correct therapeutical choice for each individualpatient. Therefore, it is still important to find proper, inexpensive, and measurable biomarkers, in order to beable to assess the efficacy of these therapies, to make personalized choices, as well as to avoid potential adversedrug reactions and side effects. The biomarkers that are available in the present vary; metabolic, microbial,cytokine-related, genetic, disease-specific and drug-specific. This review presents the existing biological agentsfor IBD and focuses both on the cascades affected by each biologic agent and on the different markers thathave been found to be indicative of their effectiveness.

The effect of synthetic leu-enkephalin (dalargin) on apoptosis and necrosis in leukocytes after cold stress on the morphological characteristics of cells and using fluorescent dyes Hoechst 33342 as well as propidium iodide was studied. The degree of cold stress influence depending on the duration of incubation of cell suspension at 0–2 and 37°C on the initiation of apoptosis and necrosis on the morphological characteristics of cells was determined. It has been proven that the ratio of apoptotic cells to necrotic ones was maximal after the use of the regimen as follows: preliminary incubation of leukocytes at 37°C – 15 min, cell exposure at 0–2°C – 15 min and subsequent incubation of leukocytes at 37°C. It has been confirmed that pre-incubation of cells with neuropeptide to cold stress affects the effectiveness of the protective action of dalargin, in particular, contributes to a significant (p ≤ 0.05) reduction in the percentage of leukocytes with morphological signs of apoptosis and necrosis. It was found that a consistent increase in temperature after cold stress to 37°C did not affect the percentage of cells with morphological signs of apoptosis and necrosis. It has been validated that the percentage of leukocytes with the apoptosis and necrosis signs after cold stress was significantly reduced after incubation of leukocytes with dalargin at a concentration of 10–9 mol/l.

The effect of local cold injury in rats on the osmotic resistance of erythrocytes in the early and late reactive terms was investigated. Cryoinfluence was performed by pressing the applicator to the skin on the lateral surface of the rat thigh for 30, 60 and 120 s. Afterwards, the blood was collected from the aorta of animals after 1 and 4 hours and after 24 and 48 hours (early and late reactive periods, respectively). The effect of hypotonic solutions on cells was used as a test for osmotic resistance of erythrocytes. It is shown that the osmotic resistance of erythrocytes in the early reactive term increases (compared with control cells). In the late reactive term, the indices of osmotic resistance of erythrocytes after 24 hours approached the control values and after 48 hours they reached the norm. Osmotic resistance of erythrocytes in both reactive terms after local cold injury does not depend on the duration of cryoinfluence (30, 60, 120 s). The findings are considered from the standpoint of adaptive reactions that have an allostatic nature.

Cryopreservation of gametes is one of the important stages of assisted reproductive technologies (ART). To obtain high results using ART, it is essential to cryopreserve sperm in a favorable season, when gametes have a high ability to fertilize oocytes. The aim of this research was to study seasonal variability of spermatozoa cryoresistance and reproductive characteristics of Saanen goats. After removing the seminal fluid, the gametes of five mature animals were cryopreserved in a solution of 10% glycerol and 20% egg yolk. The ability of spermatozoa to fertilize was examined by the embryo development rate on day 7 of in vitro culture. Reproductive characteristics of Saanen goats during the breeding season were found to be featured by increased sperm concentration and motility. The survival rate of goat spermatozoa after cryopreservation is seasonally dependent, i. e. in the breeding season the number of viable spermatozoa was notably higher than in non-breeding one. The frequency of oocyte fertilization after the use of fresh and cryopreserved spermatozoa derived in different seasons was significantly higher in the breeding season group. The number of embryos which developed to the blastocyst stage was the lowest after fertilization of oocytes with cryopreserved spermatozoa obtained in the non-breeding season. It is concluded that sperm cryotolerance and reproductive characteristics of goats are higher in a breeding season compared to non-breeding one. The findings will allow to develop a strategy in the reproduction of farm animals for the food security of Ukraine.

Authors: Quynh Nguyen Vu
Published: June 2022

This paper presents a using Radial Basis Function Neural Network (RBFNN) for PMSM to overcome the changing load. Firstly, a mathematic model of the PMSM drive is derived; then, to increase the performance of the PMSM drive system, a Fuzzy PI controller in which an RBFNN adjusts its parameters is applied to the speed controller for coping with the effect of the system dynamic uncertainty and the external load. Secondly, the Very high-speed integrated circuit Hardware Description Language (VHDL) is adopted to describe the behaviour of the speed control IC which includes the circuits of space vector pulse width modulation (SVPWM), coordinate transformation, RBFNN, and Fuzzy PI. Thirdly, the simulation work is performed by MATLAB/Simulink and ModelSim co-simulation mode, provided by Electronic Design Automation (EDA) Simulator Link. The PMSM, inverter, and speed command are performed in Simulink, and the speed controller of the PMSM drive is executed in ModelSim. Finally, the co-simulation results validate the effectiveness of the proposed algorithm based speed control system

Triterpenoids are considered to be the major pharmaceutical active compounds found in the macrofungus Ganoderma lucidum (G. lucidum). Extraction conditions of triterpenoids from the Vietnamese red G. lucidum were optimized by response surface methodology using ultrasound –assisted extraction (UAE) method. A Box – Behnken experimental design was used to determine the simultaneous influences of three independent variables, namely solvent-to-material ratio, extraction time, and ultrasonic power on the yield of triterpenoids. The highest yield of triterpenoids obtained under optimum conditions including extraction time of 55 min, ultrasonic power of 480 W, solvent-to-material ratio of 27:1 mL/g was 9.5768 ± 0.228 mg/g according to ultraviolet-visible spectroscopy (UV-Vis) analysis. Besides, the hot water extraction method was carried out in order to compare with UAE in terms of the yield of triterpenoids. The results of anticancer evaluation of the extract obtained indicated that with the half-maximal inhibitory concentration value of 67.25 ± 0.82 µg/mL on the human Hep-G2 liver cancer cell lines, triterpenoids extracted from G. lucidum could be regarded as a potential agent for medicinal treatment.

Yüce Kur’an, Müslümanlar tarafından da gayrimüslimler tarafından da üzerinde pek çok çalışmanın yürütüldüğü kutsal bir kitaptır. Dinî ve kültürel kökenleri itibariyle Türkiye, Kur’an üzerine en fazla araştırma yapılan ülkelerdendir. Ancak yapılan çalışmaların ve sunulan katkıların uluslararası düzlemde daha fazla yer edinebilmesi için Türkiye’de Kur’an üzerine yazılmış makalelerin çeşitli yönleriyle ele alınması ayrı bir önem taşımaktadır. Bu maksatla, söz konusu makaleler konulara göre tasnif edilerek; üzerinde fazlaca araştırma yapılmış konular ile nispeten daha az çalışma yapılan alanlar tespit edilmeye çalışılmıştır. Çalışma, ayrıca Kur’an üzerine yazılmış makalelerde ne kadarının disiplinler arası çalışmalara konu olduğunu saptamayı hedeflemektedir. Bu makalelerin gösterdikleri sayısal değişimler, yıllara dağılımı açısından da incelemeye alınmıştır. Kur’an üzerine Türkçe dışında bir dille yazılmış makaleler de tespit edilmiş, makalelerin içerikleri ve yazarları hakkında değerlendirmelerde bulunulmuştur. Son olarak Kur’an üzerine yazılmış makalelerdeki bazı şekil, içerik ve bilimsel usul hataları incelenmiş, makalelerde etik ihlaller bulunup bulunmadığı tetkik edilmiştir. Nihayetinde de eksikliklerin giderilmesi için çeşitli önerilerde bulunulmuştur. 2015 yılından sonra makale sayılarındaki aşırı artış araştırmayı güçleştirdiği için makaledeki tespitler 1930-2015 yılları arasındaki makalelerle sınırlandırılmıştır.

Türkiye'de yapılan din sosyolojisi çalışmaları beraberinde nesnel olanı tarafsız bir tarzda inceleme kaygısını her zaman sürdürmüştür. Ülkemizdeki çalışmaların İslam dini ve İslam temelli farklı dini gruplar üzerine yoğunlaşması metodolojik olarak din sosyolojisinin tarafsızlığı problemini gündemde tutmuştur. Bununla beraber Türk toplumunu ve İslamiyet’in hâkim din olduğu diğer toplumları anlamak, dini olduğu kadar sosyolojik olarak da ilk kaynaklara inmekle, vahyin ilk muhataplarının davranışlarını yorumlamakla mümkün olacağı dikkate alınmalıdır. Özellikle İslam tarihinin özel bir dönemi olan “Râşid Halifeler Dönemi” ictihadları, hem İslam fıkhının teşekkülünde hem de Müslüman milletlerin toplumsal yapılanmalarında şer’i ve rasyonel bir kaynak olarak refere edilmiştir. Bu bağlamda Müslüman toplumların idari ve içtimai teşekkülü meselesinde ilk dört halifenin ictihadlarının etkisi ve bu ictihadların sosyolojik veçheleri nelerdir sorusu irdelenecektir. Bir “İctihad Sosyolojisi” denemesi olacak bu çalışma, Sosyoloji ve Fıkıh ilmi için ortak bir çalışma alanı olanaklarını sorgulamayı da amaçlamaktadır.

Bu çerçevede makalenin ele aldığı problem, Dembski’nin mekansal düzenliliklere dayalı olan tasarım argümanının geçerliliği ve ikna ediciliğidir. Tasarım argümanlarının hem tarihsel hem de çağdaş verisyonları ağırlıklı olarak mekansal düzenlilikleri konu edinmektedir. Bununla birlikte, evrim kuramının bilim ve felsefe çevrelerinde yaygın kabul görmesiyle, mekansal düzenliliklere dayalı tasarım argümanları ciddi biçimde eleştirilmiştir. Bu bağlamda, makalenin amacı, mekansal düzenliliklere dayalı tasarım argümanlarının çağdaş bir örneğini felsefi bakımdan incelemek ve evrim kuramı kaynaklı itirazlara karşı gücünü koruyup koruyamadığını belirlemektir. Çalışmada nitel veri toplama yöntemlerinden literatür incelemesi kullanılmış, elde edilen veriler tutarlılık ve savunulabilirlik açısından felsefi değerlendirmeye tabi tutulmuştur. Din felsefesi, bilim ve din bağlamındaki tartışmalarda hayli kapsamlı bir yer tutan bu konu, Dembski’nin kanıtı ve ona yöneltilen itirazlar ile sınırlandırılmıştır. Bu çalışmanın sonucunda, Dembski’nin mekansal düzenliliklere dayalı tasarım argümanının evrim kuramı kaynaklı eleştiriler karşısında yeterince ikna edici olmadığı savunulacaktır.
İki Kadın, Tek Acı: Hansa ve Antigone

Bir tarafta ağıtlarıyla Cahiliye ve İslami dönemde adından çokça söz ettirmiş el-Ḫansā, diğer tarafta Sophokles’in ünlü tragedyasında karşımıza çıkan Antigone; bu iki kadının hayat hikâyeleri ve karakterlerine şekil veren trajik olaylar incelenmeye değer olduğu kadar ilginç benzerliklere de sahiptir. Her ikisi de kardeşlerini trajik bir şekilde kaybetmiş ve akabinde yaşadıkları sıkıntılar nedeniyle hüzün ve trajedinin timsali haline gelmişlerdir. Öte yandan Ḫansā’nın neredeyse isyan derecesine varan ağıtları; Antigone’un ise dinî ritüelleri yerine getirmek uğruna sarf ettiği çabalar onları farklı kılan hususiyetlerdendir. Ḫansā kendi döneminde ve daha sonraki dönemlerde adından kadın Arap şairlerin en büyüklerinden biri olarak söz ettirirken; Antigone ise Thebai kralı karşısındaki sağlam duruşu, kararlılığı ve kralın ona karşı olan söylemleriyle güçlü bir kadın figürü çizmiş, hatta feminist görüşün dayanak noktalarından birini oluşturmuş ve bu yönüyle literatürdeki yerini almıştır.
The Politics of EU towards Environmental Education and Sustainable Development

Published: June 2022

Although there are many ways to overcome environmental problems, the threat of climate change and resource depletion, which has become a global problem, forces countries to make common policies. However, some economic costs that occur at the same time prevent countries from adopting sustainable environmental policies. Therefore, this article, which emphasizes environmental education, includes examples of cooperation between countries on environmental protection and sustainable development.Environmental policies and development policies in the member states of the European Union are also among the subjects to be examined. In this way, the level of environmental policy in countries with different foreign policy priorities could be observed. The EU, which has rapidly developed its environmental policies with the effect of globalization, sets an example in this regard. Therefore, the research, it is aimed to discuss the place of environmental protection policies in the education system in European Union (EU) countries. It is seen that the current education system does not adequately focus on climate change. It has been determined that the environmental policies carried out to overcome the negative effects of environmental problems cannot be integrated into the education system or their sustainability cannot be ensured. If it is desired to have environmentally sensitive societies: It is important to improve the curriculum and analyze the international repercussions of climate challenges on education. Indeed, education is one of the most important stages of this informing process. In this article, “globalization” will also be discussed together with the EU's environmental policy and education system. Furthermore, it will be analyzed which subjects are included in the curriculum and what the differences are between European countries. There are three main titles in this study in which qualitative research method is preferred: “Introduction”, “The Effects of The Globalization on Environmental Problem”, “Environmental Education in EU and Sustainable Development”. As a result, in the light of the information obtained, it is seen that the effort to integrate the environmental policies of the European Union into the education system in economic, social, and political life dimensions continues. Considering the EU's 2030 and 2050 sustainable development goals; in addition to a sustainable environmental education policy, investments should be made in sustainable energy and sustainable urbanization policies.
Dilemas de um esporte em construção: uma análise da seção de cartas na revista Overall (1985 - 1990)
Authors: Brandão Leonardo , Fortes Rafael
Published: June 2022

Resumo Este artigo visa investigar os dilemas em torno da prática do skate através das cartas que foram publicadas na revista Overall. Essa revista contou com 19 edições entre 1985 e 1990, sendo que, ao todo, 107 cartas foram publicadas ao longo deste período. A década de 1980 pode ser compreendida como um momento-chave para a esportivização desta atividade, entretanto, ela marca, paradoxalmente, o período no qual se desencadeiam concepções ambivalentes sobre o skatismo, sobretudo acerca de sua prática nas ruas. Tais cartas foram um reflexo desse paradoxo, pois, ao passo que muitos skatistas se sentiam confiantes pela existência da Overall como um elemento de fomento desta atividade como um esporte, muitos também reclamavam das coibições e proibições que a prática ensejava.
Dilemmas of a sport under-construction: an analysis of the letter section in the Overall magazine (1985 - 1990)
Authors: Brandão Leonardo , Fortes Rafael
Published: June 2022

Abstract This article aims to investigate the dilemmas surrounding skateboarding through the letters published in Overall magazine. This magazine had 19 issues between 1985 and 1990, and in all of them, 107 letters were published during this period. The 1980s can be understood as a key moment for the sportivization of this activity, however, it paradoxically marks the period in which ambivalent conceptions about skateboarding are triggered, especially about its practice on the streets. Such letters reflect this paradox, while many skateboarders felt confident that Overall existed as an element to foster this activity as a sport, others complained about the restrictions and prohibitions the practice entailed.
Bodies, silences, and disciplines: on the ways to confine and their possible educations
Authors: Bocchetti André
Published: June 2022

Abstract The text analyzes the issue of silence in a contemporary context, thinking from its double Latin meaning: that of taceo, as silencing; and that of sileo, as a silence that expands subjective spaces of creation, suspending previous significant codifications. The analysis goes through the relationships between ways of silence and discipline (of oneself or the other) and their reverberations in the bodies, based on the thoughts of Michel Foucault and José Gil. The reflection culminates thinking about the silence that sometimes operates as moralizing pedagogy, other times as a pedagogical act that opens space for new modes of existence.
Inclusión sociocomunitaria y ocupaciones colectivas: Diálogos entre el mundo institucional y el de las organizaciones de personas con discapacidad psicosocial
Authors: Angulo Rodrigo Javier Vera , Molina Valeria Alicia Parra , Carrasco Cristóbal Rodrigo Sepúlveda
Published: June 2022

Resumen El artículo analiza, prácticas de inclusión socio comunitaria, de agrupaciones de personas con discapacidad psicosocial, generadas en el hacer y sentir en sus ocupaciones colectivas, a partir de los diálogos que se producen con las instituciones sociales. Se empleó una metodología cualitativa, con enfoque crítico. La información fue recolectada mediante grupos de discusión, lo que permitió recoger discursos de los participantes de dos agrupaciones de personas con discapacidad psicosocial, correspondientes a las comunas de Penco y Concepción, de la Región del Biobío (Chile); discursos que fueron codificados, analizados, categorizados e interpretados. Entre los resultados más relevantes obtenidos, se evidencian diferencias y tensiones en las formas de comprender y proceder hacia la inclusión, pues las instituciones tienden a mantener relaciones jerárquicas, mientras que las agrupaciones propenden a prácticas más democráticas y participativas. Con respecto a las conclusiones, es posible visualizar que los derechos humanos de las personas con discapacidad psicosocial se materializan en un campo de ocupaciones colectivas, de acciones diarias en contextos cotidianos y de conflicto social.

The production of suitable coatings with excellent antibacterial performance has now become a viable technique for enhancing the functional qualities of various biomedical materials. Here, pulsed plasma polymerisation was used to produce an antibacterial coating from the carvone oil of the spearmint plant. The coating films have adjustable chemical and physical properties based on the deposition parameter – that is, duty cycle (DC). The static water contact angle (WCA) values of pulsed wave (PW) plasma-polymerised carvone (ppCar) increase with the increase in DC. Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy showed that the molecular structure of carvone is less fragmented, retaining moieties associated with C–O and C=O when the DC is reduced. These C–O and C=O moieties likely reduced the measured static WCA. This surface chemical composition with predominantly C–O and C=O also showed a stronger bactericidal effect, based on the biofilm assay with bacteria (Escherichia coli and Staphylococcus aureus), compared with those coatings with C–C and C–H produced at a higher DC. As shown by the atomic force microscopy images, a lower DC resulted in smoother and more homogeneous coatings than those produced with a higher DC, while field emission scanning electron microscopy images show that when E. coli and S. aureus membranes were attached to PW ppCar, they ruptured and distorted with a pore created and that these distortions and ruptures increased as the DC was reduced.

Mental health at work – The psy50 as an integrative approach to the measurement of working conditions Work can either stabilize or impair mental health. Thus, factors that support well-being and commitment must be considered in addition to burdens and stressors. Further, without knowledge of the mental well-being or engagement of the workers, the assessment of psychosocial working conditions remains incomplete. Long-term studies show that the lack of or variation in resources correlates more strongly with engagement, emotional well-being or health-related productivity losses than stressors. The effects differ across personality types. Methodological advances allow the development of compact screening instruments which cover all relevant constructs yet can be completed in less than 10 minutes. The second part of the article presents such an instrument, the psy50. The instrument was developed over several years in cooperation with the BKK umbrella organization, the Federal Ministry of Labour, experts and employees as part of the psyGA project. Keywords: workplace conditions – mental health – personality – measuring psychosocial working conditions
