Objetivo: Analisar na literatura científica sobre a relação do estrogênio no risco cardiovascular. Métodos: Essa Revisão Integrativa utilizou plataformas, como PubMed, SciELO, Lilacs e Clinical Trials, para encontrar fontes relevantes para desenvolver este projeto. Descritores em Ciências da Saúde como “cardiovascular risk”, “cardiology”, “cardiology risk”, “estrogen”, “estrogen replacement”, “menopause”, “primary health care” e "hypertension" em associação com operadores booleanos foram usados para pesquisa nessas plataformas científicas, resultando em 2653 artigos. Dentro desses números, devido aos critérios de inclusão e exclusão, apenas 20 tornaram-se fontes oficiais. Resultados: Estudos mostram que o estrogênio tem papel importante na regulação do tônus vascular, evitando a remodelação vascular e, consequentemente, diminuindo o risco cardiovascular. Ainda, a deficiência de estrogênio contribui para o desenvolvimento de hipertensão durante a menopausa devido ao hormônio ovariano vasodilatador circulante reduzido, que causa colapso do sistema circulatório junto com a formação de placas ateroscleróticas. Por outro lado, a reposição hormonal durante a menopausa aumenta a chance de eventos trombóticos. Considerações finais: O estrogênio atua como fator protetor do risco cardiovascular, porém é muito importante considerar outros elementos de risco, como presença de comorbidades, tipos de reposição estrogênica e via de administração de medicamentos, para definir a conduta do paciente.
Perianal Inflammation or Something More?
Authors: Dsouza Romina Geraldine , Al Rasheed Mohamed Rizwan Haroon , Low Gavin
Published: September 2021

Perianal fistulae are commonly complicated by abscesses and ramifications, which have well-recognized imaging morphology. Less commonly, atypical findings of solid enhancing mass-like lesions with no fluid component are associated with chronic and recurrent fistulae, the etiology of which includes inflammatory masses as well as locally aggressive malignancy. The latter predicts poorer prognosis and warrants extensive surgical resection. The reading radiologist must identify the unusual appearance, be aware of the possible etiologies, and if appropriate recommend prompt tissue sampling to exclude malignancy. This is pertinent as it determines surgical management, which is crucial in achieving a potential curative outcome.

Published: September 2021

Cette recherche vise l’inventaire et la sélection de coproduits agricoles d’intérêt pour l’élevage d’Hermetia illucens (L. 1758) au Bénin. Les données relatives à la nature, la disponibilité et la valeur marchande des coproduits agricoles ont été collectées à travers une enquête dans 8 départements du Bénin. Deux régimes expérimentaux isoprotéiques et isolipidiques ont été formulés à partir de trois coproduits principaux (tourteau de coton, son de maïs et abats de poisson) et testés sur la croissance larvaire et la qualité nutritionnelle des prépupes d’H. illucens. 28 coproduits agricoles ont été recensés et répartis en 3 groupes : les tourteaux, les résidus et les sons. Le substrat à base de son de maïs et d’abats de poisson favorise une croissance optimale des larves. Les teneurs en protéines (47,89 ± 0,11 %) et en lipides (26,75 ± 0,29 %) des prépupes issues de ce régime permettent de répondre aux besoins nutritionnels du tilapia du Nil. Le régime à base de tourteau de coton a induit une forte mortalité (67,33 ± 3,96 %) chez les larves d’H. illucens. Sur la base des facteurs de disponibilité, de compétition et des résultats de l’expérimentation, 22 coproduits agricoles sont retenus pour de futurs essais.

Stories, places: storied place and placed story

. . . the universe is not simply a place but a story –a story in which we are immersed, to which we belong, and out of which we arose. –Brian Swimme & Mary Evelyn Tucker

ABSTRACT

For a while now I have been ‘wondering’ about, pondering the link between story and place, inhabitant and colonizer: the inextricable and intractable connections that come into being between them. And so in this short diffractive piece where a constellation of concepts (space, place, story, performance, hospitality, refrain, vibe, power to/power over, rhizomes etc.,) come together with no one ‘truth’ privileged, I hope to explore those connections and provide some compelling examples of story as place and place as story with particular reference to one particular place, a school, and the inhabitants of one particular classroom in that school in Cape Town, South Africa. For in schools where matter, in all its forms, is ‘storied’–has its own story to tell–and storified, stories matter.

Authors: Bawazeer A. A. , Hattab A. S. , Morales E.
Published: September 2021

The objectives of this study were first to estimate the prevalence of cigarette smoking among secondary-school students and then to identify and analyse the demographic, social and cultural risk factors associated with the first cigarette smoking experience. A sample comprising 1000 students was selected randomly. Results showed that 19.6% of the total sample smoked; 15.5% among females and 21.9% among males. Family and/or friends appeared to influence the first cigarette experience and thus prevention strategies should involve not only the students themselves but the home, school and social environments also
Haemolytic potential of three chemotherapeutic agents and aspirin in glucose-6-phosphate dehydrogenase deficiency
Authors: Ali N. A. J. , Al Naama L. M. , Khalid L. O.
Published: September 2021

The potential haemolytic effect of three chemotherapeutic drugs and aspirin was tested in vitro by gluthathione stability tests. Blood was collected from the local population of Basra, Iraq where previous studies had found a high frequency of glucose-6-phosphate dehydrogenase [G6PD] deficiency. Primaquine, chloramphenicol and sulfanilamide caused significant concentration-dependent reductions of glutathione levels in G6PD-deficient red cells when compared to normal red cells. Acetylsalicylic acid had no effect on glutathione level. The G6PD-deficient erythrocytes behaved as previously reported, probably due to similar patterns in the distribution of its variants. Studies on each local variant are warranted and new drugs should be tested for haemolytic potential prior to their introduction in areas where the deficiency is common
Removing hepatitis C virus from polytetrafluoroethylene-coated orthodontic archwires and other dental instruments
Authors: Ramadan A. A.
Published: September 2021

Thefficacy of removing, rather than destroying, hepatitis C virus [HCV] from polytetrafluoroethylene [PTFE] -coated orthodontic archwires was tested. PTFE-coated archwires, pieces of PTFE and endodontic files [20 each] were immersed in HCV-infected blood for 24 hours. Half were washed under running water for 10 seconds while the remainder were thoroughly scrubbed with a toothbrush under running water for 10 seconds. Items were kept in separate dishes of distilled water for 24 hours. Reverse transcription polymerase chain reaction was used for viral replication. Viruses were detected by the gel method using a transilluminator. Only scrubbed PTFE pieces and coated archwires were negative for HCV. This suggests that PTFE coating of dental instruments inhibited HCV adhesion when thoroughly scrubbed

Published: September 2021

Datafrom all 148 cases of oesophageal cancer in Bahrain during 1952-99 were analysed according to patient sex and age and site and histological pattern of tumour, and compared with other Gulf countries. In Bahrain, oesophageal cancer accounted for 2.6% of malignant neoplasms. The female: male ratio was 1.8: 1, and the majority of patients were >/=51 years and </=70 years of age. The lower and upper third of the oesophagus were the most and least frequently involved sites, respectively. Squamous carcinoma [males] and adenocarcinoma [females] were the main histological types. There is varying consistency between these data and those of other Gulf countries having similar anthropological and demographic profiles. A prospective study may help to better underst and the aetiology of the disease and inform preventive policies

Published: September 2021

Serum transforming growth factor-beta [TGF-beta1] production was estimated for 10 patients with essential hypertension, 12 patients with glomerulonephritis [5 hypertensive and 7 normotensive] and 10 healthy controls. The glomerulonephritis group received angiotensin-converting enzyme inhibitor captopril 25-75 mg/day for 4 weeks. Blood urea, serum creatinine, 24-hour urinary protein and serum TGF-beta1 were then re-estimated. Urea and creatinine were significantly higher in the hypertension and glomerulonephritis groups than in the controls and also higher in the glomerulonephritis group than the hypertension group. TGF-beta1 was significantly higher in the glomerulonephritis groups than in the control and hypertension groups. TGF-beta1 and 24-hour urinary protein were significantly reduced in the glomerulonephritis group
Clima y concentraciones de polen de gramíneas en el País Vasco
Authors: Rasilla Álvarez Domingo Fernando
Published: September 2021

La información sobre los niveles de calidad del aire en las ciudades españolas raramente incluye las partículas de origen orgánico, de las que el polen es un componente fundamental, responsable de numerosas patologías respiratorias y un buen marcador de los cambios ambientales. Este trabajo analiza la relación entre el polen de gramíneas medido en las tres capitales vascas y las condiciones atmosféricas, tanto a escala local como regional. Los resultados sugieren que una parte sustancial del polen de gramíneas medido en el País Vasco procede de ámbitos ajenos a esa Comunidad Autónoma, arrastrado por vientos de componente S y E y situaciones sinópticas del SW y SSE.

Published: September 2021

The article presents an analysis of the impact of climate change on the main characteristics of ice phenomena, snow cover and the water regime in the Small Northern Dvina River basin occurring in recent decades. Recently, a significant climate warming has been observed in the basin. As a result, winters are getting warmer and shorter. There is also an increase in winter precipitation and the number of thaws. Climate warming directly affects the duration of snow cover, which decreases both due to the later formation and to the earlier destruction of snow. There is also a slight downward trend in the annual values of the maximum snow water equivalent, which may be the result of an increase in the number of thaws in winter, when a part of the snow cover melts contributing to the winter river runoff. The analysis of the main characteristics of the ice cover on the rivers of the studied basin shows that their changes are similarly to changes in the snow cover: there is a reduction in the freeze-up period due to its later formation and earlier complete destruction. The maximum ice thickness on the rivers of the basin also tends to decrease. There is an increase in winter and a decrease in spring runoff. Predictive estimates of changes in the observed trends in the future are presented in the fi nal part of the article based on the CMIP5 project data.
CRITICAL ASSESSMENT OF THE IMPLEMENTATION OF TARGET PROGRAMS IN SOLVING THE PROBLEM OF TECHNICAL RE-EQUIPMENT OF AGRICULTURE
Authors:   Russian State Agrarian University - Moscow Timiryazev Agricultural Academy, GONCHAROV ANTON A.
Published: September 2021

Over the years of results-based management, the agricultural sector of Russia has enhanced a signifi cant increase in production volumes. Special results have been achieved in crop production, primarily in the production of grain crops. This was urgent in terms of meeting the needs of the domestic market and increasing the volume of supplies to foreign markets. Despite a number of positive results achieved in agriculture through the implementation of targeted programs, especially during the period of counter-Russian sanctions and the ongoing policy of import substitution, the problem of providing the industry with means of production has not been fully solved. This hinders the implementation of Russia’s export capacity. To further increase the volume of agricultural production, the technical re-equipment of the industry is required, which will increase the effi ciency of production. To this end, it is necessary to critically evaluate the implementation of targeted programs used to solve the problem of technical re-equipment. This indicates the relevance of the research topic. The study was conducted on the basis of a systematic approach (monographic, economic and statistical methods, the method of deduction) with the use of relevant materials of offi cial statistics. During the implementation of targeted programs, the pace of technical re-equipment of agriculture was extremely low, accompanied by a considerable share of obsolete imported agricultural machinery, tractors and combine harvesters, and decresing energy supply of the industry. Insuffi cient provision of agriculture with means of production constrains the growth rate of labor productivity. The targets set in the State Program for the renewal of agricultural machinery are low and have been exceeded for several previous years, and they do not indicate a high rate of technical re-equipment of agriculture. The study results serve as a basis for adjusting the current mechanism of results-based management of agricultural development.
DEVICE AND METHOD FOR CONTROLLING MICROWAVE SEED TREATMENT ON A CONVEYOR BELT
Authors:   Russian State Agrarian University - Moscow Timiryazev Agricultural Academy, MALAKHOV ALEKSANDR N.
Published: September 2021

The sowing qualities of seeds – such as germination, germination energy, weight of 1000 seeds, etc., are the factors ensuring high yields of agricultural crops. Technological methods of seed and grain treatment with the UHF MEMF (microwave electromagnetic fi eld of ultrahigh frequency) energy involve the use of various types of microwave devices, diff ering both in operating principle and in design. In fact, the process of microwave treatment of seeds is similar to the process of heat treatment of dielectric materials. Therefore, depending on the goal of treatment, microwave devices should provide some kind of selectivity of microwave heating, a high conversion factor of microwave energy into thermal energy, uniformity of microwave treatment of the bulk of material, protection of the microwave generator and electromagnetic safety. During the microwave treatment of seeds, it is important to ensure uniform treatment of the bulk of seeds and automatically maintain optimal treatment modes (microwave heating modes). An installation design is proposed for microwave treatment of seeds. A specifi c feature of the proposed design is that seeds are processed on a moving belt under an emitter with the process control and regulation according to the speed and fi nal heating temperature. Moreover, the microwave source intensity depends on the load (a layer of seeds on the conveyor belt). The authors also propose an algorithm for the microprocessor control of the device. Thus, the proposed design of the installation for treating seeds in a layer under the emitter on a moving conveyor belt, as well as the technological algorithm for matching the microwave source with the load ensure the compliance with the processing modes in strictly specifi ed ranges of the fi nal temperature and microwave heating rate of the material, as well as protect the microwave source from refl ected electromagnetic waves.
DOSED-CAPACITY ELECTRODE WATER HEATER USED IN BOILING AND HEATING INSTALLATIONS
Authors:   Russian State Agrarian University - Moscow Timiryazev Agricultural Academy, SHICHKOV LEONID P.
Published: September 2021

Power change of electrode water heaters depending on the water quality is their main disadvantage. To eliminate this drawback and improve the reliability of water heaters, an electrode water heating system was developed and its operating mode was analyzed. The paper considers an aggregated system of electric water heating, consisting of a single-phase electrode water heater connected to a single-phase network via a valve-capacitor converter with a metered energy transfer. To regulate and stabilize the heating power, the storage capacity of the converter is divided into separate sections. The performed formula analysis of the load mode of the aggregated system allows optimizing its operation mode. In order to increase the safety and ease of operation of the installation, additional interlocks of the corresponding electrical circuits are provided in the electrical circuit. The authors conclude that it is advisable to use single-phase electrode water heaters by switching on through a valve-condenser converter with dosed energy transfer, which allows regulating and stabilizing the heating power and thereby increasing electrical safety, functionality, reliability of electrode water heaters, as well as ensuring a signifi cant improvement in the quality of operation.
The Effect of Recombinant Vascular Endothelial Growth Factor (VEGF)-121 Towards Placenta Growth Factor Serum Levels in Female Mice (Mus Musculus) with Preeclampsia Model
Authors: Prabowo Wisnu
Published: September 2021

Background: Preeclampsia is a multi syste­mic disease which recognized by the develop­ment of hypertension after 20 weeks of gesta­tion with the presence of proteinuria or any signs indicative of target organ injury. The correct diagnosis and classification of the disease are essential since the therapies are unique in each class. Moreover, the angiogenic factors claims to play a significant role in the endothelial injury which plays as an etiology for preeclampsia. Thus, this study aimed to analyze the differences between angiogenic factors in pregnancy mice with preeclampsia models after administration of VEGF-121.
Subjects and Method: Subject of the study were swiss’s strains of pregnancy mice (Mus musculus) which divided into three groups that consist of 10 subject of study in each group. Subjects for this research were recruited between March and May 2015 in Biomedical Laboratory of The Faculty of Veterinary Medicine, Universitas Airlangga as part of a cross sectional study designed for analytical experimental. The angiogenic factor which measured was PIGF serum levels with ELISA method and only group of pregnant mice with preeclampsia model which administred with injection of VEGF-121.
Results: This study was conducted of 30 male and 30 female Mus musculus with homoge­neous characteristic in terms of age, average body weight and have never been pregnant before. The differences in PIGF serum levels between three observed group are significant (p=0.035).
Conclusion: Administration of VEGF-121 increased the PlGF serum levels in pregnant mice with preeclampsia model. Thus, the admi­nistration of VEGF-121 improves the condition of endothelial damage in preeclampsia with an increase in PlGF levels.

Published: September 2021

Background: Ectopic pregnancy is an import­ant cause of maternal morbidity and mortality, estimated to occur in approximately 1-2% of pregnancies worldwide. Smoking and history of using intrauterine devices are risk factors for ectopic pregnancy. This study aims to estimate the magnitude of the relationship between smoking and a history of using intrauterine devices on the incidence of ectopic pregnancy based on a number of previous primary studies.
Subjects and Method: This study is a syste­matic review and meta-analysis. The articles used in this study were obtained from several databases, including: PubMed, Google Scholar, and Science Direct which were published from 2000-2020. The inclusion criteria used are full text articles with Case Control design. The keywords used to search for articles were as follows: smoking AND "ectopic pregnancy" AND multivariate; "use of intrauterine device" AND "ectopic pregnancy" AND multivariate; smoking OR cigarette AND “use of intrauterine device” AND “ectopic pregnancy” OR “tubal pregnancy” AND multivariate. Articles were collected using PRISMA flow diagrams and analyzed using the Review Manager 5.3.
Results: A meta-analysis of 7 articles showed that women of reproductive age who smoked had a 2.20 times risk of ectopic pregnancy compared to women of reproductive age who did not smoke (aOR= 2.20; 95% CI= 1.45 to 3.34; p= 0.002). A meta-analysis of 9 articles showed that women of reproductive age with a history of using intrauterine devices had a 2.28 times risk of ectopic pregnancy compared to women of reproductive age who did not use intrauterine devices (aOR= 2.28; 95% CI= 1.74 to 2.98; p<0.001).
Conclusion: Smoking and a history of using intrauterine devices increase the risk of ectopic pregnancy.
THE FORMATION OF THE HISTORICAL AND LITURGICAL RESEARCH AREA IN RUSSIAN ACADEMIC SCHOLARSHIP IN THE LATE 19TH – EARLY 20TH CENTURY. A COMPARATIVE ANALYSIS OF METHODOLOGICAL APPROACHES OF N.V. POKROVSKY AND I.A. KARABINOV
Authors:   St. Philaret’s Orthodox Christian Institute, Dashevskaya Zoya M.
Published: September 2021

n the second half of the 19th century – especially in the period following the introduction of the Academic Constitution of 1869, and in the 1880s and continuing until the forced closure of Theological Academies after the Revolutionary coup – the historical and liturgical research area in Russian academic science experienced a period of its formation and flourishing. The subject of the article is a comparison of approaches to the study of the worship service history and analysis of the formation of the research methodology for teaching Liturgics by professors N.V. Pokrovsky and I.A. Karabinov of the St. Petersburg Theological Academy, where they taught the history of Christian worship from the 1880’s until its forced closure in 1918. Analysis and juxtapos- ing of academic courses in Liturgics allows defining the boundaries and content of the discipline in the period of its formation as well as considering the evolu- tion in research methodology and, more broadly, the formation of the Russian historical and liturgical scientific school. A comparison of the courses reveals the authors attitudes towards histori- cal sources material and its studies. Their own ideas about the provenance of various rites used in church worship characterize their views on the develop- ment of the liturgical tradition, expressing their approaches to its study and thereby form our picture of the establishment of historical Liturgics as a field of researchable knowledge.
P.M. GOLOVACHEV. THE FAR EAST IN THE THOUGHTS OF THE HISTORIAN
Authors:   Russian State University for the Humanities, Medvedev Konstantin A.
Published: September 2021

The author of the article makes an attempt to analyze the views of Russian historian Peter Mikhailovich Golovachev. Those views concerned issues of Russian policy in the Far East in the late 19 th – early 20 th century. The basis of the article is analyzing P.M. Golovachev’s treatise “Russia in the Far East”. The author of the article intends not only to research different aspects of Russian Far Eastern policy raised in that treatise. The analysis of intellectual context has an equal significance. The author makes an attempt to represent specific features of Russian public thought at the turn of the ages. Researching of P.M. Golovachev’s views enables to identify several intellectual transformations concerned Russian society’s visions of the Far East. The author of the article emphasizes that historical knowledge allowed P.M. Golovachev having an unconventional approach to the consideration of issues of interest to the Russian public. The latter was expressed, in particular, in criticism of well-established ideas and concepts. The author concludes arguing that P.M. Golovachev’s work was the great example of the Far East development project. The emergence of such projects became the forerunner of the sphere of knowledge, which later became known as “geopolitics”.
THE “TURNING POINT” IN THE SECOND WORLD WAR: CONTEMPORARY SCHOLAR DISCUSSIONS
Authors:   Moscow State Institute of International Relations, Magadeev Iskander E.
Published: September 2021

The aim of the article is to review the contemporary scholar discussions which take place in the Russian and foreign historiography about the “turning point” in the Second World War. The use of the “turning point” term by scholars was inevitably linked to the question about the relative con - tribution made by the countries of the “Grand Alliance” to the victory over the “Axis Powers”. Thus, it was logical that after 1945, during the rise of the Cold War, the academic and media discussions about the “turning point” had not only a historiographical but also political significance. Such disputes continue nowadays. This article analyses one of the recent revisionist conceptions about the “turning point” proposed by the British historian Ph. O’Brien. He tried to revise the widely held thesis that the huge land battles at the Soviet-German front were crucial to the outcome of the whole war. A critical evaluation of O’Brien’s conception is fruitful to the further scholar research on the topic as well as to the understanding of the historiographical process itself.
dimensão ética do currículo
Authors: Nicolay Deniz Alcione
Published: September 2021

O presente artigo tem como objetivo inicial resgatar noções clássicas da filosofia antiga no campo do currículo. Entre essas noções destacamos as concepções de: ética, comunidade, humanismo e natureza. Desse modo, consideramos que tais noções só fazem sentido quando pensadas no ideal da Paidéia grega (JAEGER, 1994). Por isso, resgatamos passagens da Republica de Platão e da Ética de Aristóteles. Por meio dessas passagens, valendo-se de analise comparativa, compreendemos a diferença entre o saber-fazer do primeiro em detrimento ao saber-agir do segundo. Nesse sentido, a ética, com Aristóteles, recebe um componente pedagógico, a virtude intelectual conhecida por phronesis (prudência). Assim, com prudência e clareza da condição ética política, podemos superar a moralização contemporânea.

Os resultados do inquérito aplicado aos professores dos cursos de Biblioteconomia da Região Nordeste do Brasil que serão abordados neste trabalho, mostram claramente o impacto do OA no Brasil e, de uma forma muito especifica, nas comunidades acadêmicas da área de Biblioteconomia no Nordeste do Brasil.
Accountability: novo conceito para a Ciência da Informação?
Authors: Rêgo Herbert de Oliveira , Freire Isa Maria
Published: September 2021

Discorre sobre as mudanças ocorridas na gestão pública no Brasil, nas últimas décadas, oriundas de transformações impostas pela Constituição de 1988 e pelo crescimento de um movimento de cidadanização, no contexto da disseminação das tecnologias digitais de comunicação e informação. Ressalta que há uma lacuna dessa discussão na literatura da Ciência da Informação e discute o contexto da accountability e da transparência no Brasil, e as políticas de informação na sociedade em rede. Destaca a necessidade de uma concepção do que seja accountability para a Ciência da Informação, de modo que os profissionais da área assumam o protagonismo no movimento da cidadania para a transparência, na implantação dos portais de transparência, no contexto da interatividade comunicativa e da ação responsável no campo da informação.
