Authors: Moon Sun Joon , Choe Hun Jee , Kwak Soo Heon , Jung Hye Seung , Park Kyong Soo , Cho Young Min
Published: October 2021

Background: Prevailing insulin regimens for glycemic control in hospitalized patients have changed over time. We aimed to determine whether the current basal-bolus insulin (BBI) regimen is superior to the previous insulin regimen, mainly comprising split-mixed insulin therapy.Methods: This was a single tertiary center, retrospective observational study that included non-critically ill patients with type 2 diabetes mellitus who were treated with split-mixed insulin regimens from 2004 to 2007 (period 1) and with BBI from 2008 to 2018 (period 2). Patients from each period were analyzed after propensity score matching. The mean difference in glucose levels and the achievement of fasting and preprandial glycemic targets by day 6 of admission were assessed. The total daily insulin dose, incidence of hypoglycemia, and length of hospital stay were also evaluated.Results: Among 244 patients from each period, both fasting glucose (estimated mean±standard error, 147.4±3.1 mg/dL vs. 129.4±3.2 mg/dL, P<0.001, day 6) and preprandial glucose (177.7±2.8 mg/dL vs. 152.8±2.8 mg/dL, P<0.001, day 6) were lower in period 2 than in period 1. By day 6 of hospital admission, 42.6% and 67.2% of patients achieved a preprandial glycemic target of <140 mg/dL in periods 1 and 2, respectively (relative risk, 2.00; 95% confidence interval, 1.54 to 2.59), without an increased incidence of hypoglycemia. Length of stay was shorter in period 2 (10.23±0.26 days vs. 8.70±0.26 days, P<0.001).Conclusion: BBI improved glycemic control in a more efficacious manner than a split-mixed insulin regimen without increasing the risk of hypoglycemia in a hospital setting.

The risk of tumours, including pheochromocytoma and gastrointestinal stromal tumour is higher in patients with neurofibromatosis Type 1 (NF1). The co-occurrence of these two tumours is rare, and most patients are symptomatic. In this case report we describe the case of an asymptomatic 42-year-old female patient with left adrenal mass and concurrent lesion in the jejunum, just distal to the ligament of Treitz. Both tumours were successfully simultaneously removed by totally robotic transperitoneal technique using da Vinci Robotic Surgical System Xi.
Laparo-endoscopic transgastric resection of gastric gastrointestinal stromal tumor located near the gastro-oesophageal junction with hiatus hernia repair
Authors: Mishra Richa , Gautam Suryanarayan , Misra Saurabh
Published: October 2021

A 63-year-old male presented to us with upper abdominal pain and odynophagia for 3 months. Contrast-enhanced computed tomography of the abdomen revealed hiatus hernia with ulceroproliferative growth involving the gastro-oesophageal (GE) junction and cardia of the stomach with no obvious transserosal extension. Upper gastrointestinal (GI) endoscopy was suggestive of a tumour of size 3 cm × 3 cm near the GE junction and sliding hiatus hernia. Although there are various ways described in the literature for managing GI stromal tumour (GIST), we opted for laparo-endoscopic transgastric resection with hiatus hernia repair due to obvious advantages in terms of safety and efficacy. Just a handful of cases have been described in the literature being treated in this fashion. The procedure was successfully performed as evidenced by an uneventful recovery of the patient. His histopathology report was suggestive of GIST of size 3.5 cm × 3.0 cm × 2.0 cm. The resected margins were free of the tumour.

Published: October 2021

Objectives:

Renal cell carcinoma (RCC) was the most common and lethal urological malignancy with the dismal outcome when distant metastasis. Melatonin was known as a potential oncostatic agent against several types of malignancy and sorafenib had been considered as an agent to treat RCC, but the synergistic effects of melatonin and sorafenib on human RCC have not been elucidated.

Materials and Methods:

Human renal cancer cell lines (Caki-1 and ACHN) were treated with melatonin combined with sorafenib were detected the cell growth and cell cycle by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide assay and flow cytometry. The ability of cell migration/invasion was performed with in vitro migration and invasion assay. The proteins and mRNA expression of metastasis-associated protein 2 (MTA2) from the RCC cells were measured by quantitative reverse transcription-polymerase chain reaction and western blotting. Clinical significance of MTA2 in RCC tissues was analyzed from The Cancer Genome Atlas database by using TISIDB software.

Results:

Our results showed that melatonin combined with sorafenib, sorafenib or melatonin-treated alone did not induce the cytotoxic effects or cell cycle arrest in human RCC cells and HK2 cells. Additionally, cotreatment with melatonin and sorafenib synergistically reduced migration and invasion in human Caki-1 and ACHN cells through synergistically suppression of MTA2 expression. Bioinformatics analysis showed that MTA2 expression significantly correlated with overall survival (P < 0.002), tumor grade (P < 0.001) and tumor stage (P < 0.001) in human RCC.

Conclusion:

Our results demonstrated that concomitantly used melatonin and sorafenib could significantly reduce the abilities of migration and invasion of RCC cells through inhibiting MTA2. We considered that this novel promising combination strategy towards the treatment of RCC, but further studies are warranted.

Performance of Exile: Poet-Translators in the Leningrad Underground

Literary translation during the Soviet period has been mostly analysed in terms of conforming to or resisting the dominant ideology. However, there were spaces where translation practices were to a certain extent free from this dichotomy, though excluded from the official literary field. The focus of the article is the particular condition of displacement or exile experienced by the underground poets who lived in Leningrad during the 1980s. The samizdat poet-translator plays the role of an exile, living on the fringes of the society and creating a network in the underground. The outcomes of this “performance of exile” are the translated texts, which show the handprints of the translator’s conditions. The article responds to Anthony Pym’s call for humanizing Translation History, and using the sociological tools developed in Translation Studies by Daniel Simeoni and Moira Inghilleri, it investigates the role of context, agent and text in the poetry translation practice of late samizdat.
Tłumacz-polemista. Zderzenie paradygmatów w pierwszym polskim wydaniu Orientalizmu Edwarda Saida
Authors: Szwebs Weronika

Translator as Polemicist: The Clash of Paradigms in the First Polish Edition of Said’s Orientalism

The article analyzes the paratextual activity of Witold Kalinowski, the author of the first Polish translation of Edward Said’s Orientalism (1991), paying special attention to his polemical remarks and their relation to the vision of scientific, theoretical discourse. The translator does not strive for invisibility. On the contrary, he uses footnotes and brackets inserted in the main text to comment on different aspects of Said’s work. He signals problems ensuing from the differences between languages and cultures, explains the nature of linguistic difficulties and justifies his own solutions. He also takes on the role of editor and commentator, explaining Said’s allusions, supplementing the discussion with additional information, anticipating readers’ doubts about certain facts that might sound suspicious, and even inserting bracketed additions and clarifications which suggest that the original is unclear or imprecise. Finally, Kalinowski overtly expresses his polemical attitude: he provides certain parts of Said’s discussion with sic! annotation (thus suggesting that the author is wrong) and adds footnotes where he argues with what he sees as the author’s dubious and far-fetched interpretations. The Translator’s Note gives certain insight into the nature of the disagreement between the author and the translator. Explaining why Orientalism is a difficult book to translate, Kalinowski enumerates its troubling features: the combination of different types of discourse and the large number of polemical accents, due to which the book is not fully scientific. The moment of the book’s publication might suggest that such a qualification could have been a result of the then scarce presence of poststructuralist thought and cultural studies in the Polish humanities. However, the analysis of Witold Kalinowski’s articles as well as his doctoral thesis from the 1980s shows both his awareness of the theoretical currents that influenced Orientalism and his critical attitude towards Marxist thought. It is the aversion to the Marxist-inspired interpretations – both Kalinowski’s personal methodological conviction and a widespread attitude in the early post-communist Poland – that seems to be the reason of the clash in the first Polish translation of Said’s work.
La organización administrativa de la investigación sanitaria en Andalucía. Algunas consideraciones en torno a la fallida proposición de ley de creación del Instituto Andaluz de Salud
Authors: Bueno Armijo Antonio
Published: October 2021

Durante las tres últimas décadas, la Comunidad Autónoma de Andalucía ha desarrollado su propia política pública de I+D en materia sanitaria y de salud pública. Esta política pública, sin embargo, se ha hecho descansar fundamentalmente sobre entes privados instrumentales creados por la propia Administración y regidos por el Derecho Privado. Como resultado, esta política ha estado sometida a un régimen jurídico altamente disfuncional para los intereses públicos. Una reciente proposición de ley planteó la sustitución de estos entes instrumentales privados por una nueva Agencia administrativa de investigación sometida al Derecho Público. Aunque la proposición entró rápidamente en vía muerta, el presente trabajo analiza los principales cambios que proponía, sus fundamentos jurídicos y su posible impacto en la situación actual.

LEACHING OF URANIUM ORES IN THE PROCESS OF SODIUM SULPHATE ELECTROLYSIS
Authors: Nefedov V.G. , Sknar Yu.E. , Kharytonova O.A.
Published: October 2021

When uranium is extracted from concentrates with high silicon content, acid leaching is usually used. The disadvantage of this method is the high consumption, high cost and corrosion activity of the reagents. Moreover, for the oxidation of tetravalent uranium to highly soluble hexavalent uranium, it is necessary to process it with oxidizing agents, for example, oxygen. The work shows the possibility of development and chemical concentration of uranium ores using electrolysis of sodium sulfate. During electrolysis the pH in the anode chambers ranges from 2.2…2.5 to 0.5…0.7 in the near-electrode layer of the electrolyte, which corresponds to the pH range during leaching in agitators. Oxygen released at the anode is able to oxidize uranium to hexavalent one.

A COMPARATIVE STUDY OF THE RADIOLYSIS OF USED TRANSFORMER OIL AND OIL CONTAINING 1, 2, 4-TRICHLORBENZENE UNDER THE INFLUENCE
OF GAMMA-RADIATION
Authors: Iskenderova Z.I.
Published: October 2021

A comparative study of the radiolysis of used transformer oil and oil containing 1, 2, 4-trichlorbenzene (TCB) under the influence of gamma-radiation was carried out. Dependence of concentration of H2, H2O2, pH-indicator and IR-spectra of γ-irradiated samples from absorbed doses in the range of 4…136 kGy was studied. The pH-value dependence and concentration of hydrogen peroxide as a function of the absorbed dose is studied. Irradiation leads to increasing of acidity, related with dechlorination of TCB molecules. It is found that during the radiolysis of transformer oil containing TCB in the presence of dissolved oxygen, radiation-initiated oxidation of the oil takes place (formation of H2O2, CO2).

SITUATIONAL CRIME PREVENTION AS A KIND OF CRIMINOLOGICAL CRIME PREVENTION
Authors: Kuzmin Yury A.
Published: October 2021

The article raises the problem of situational crime prevention as a type of criminological crime prevention. The urgency of issues related to situational crime prevention, which is aimed at eliminating conditions directly facilitating crimes, has been substantiated. One of the most effective ways to prevent criminal acts is to eliminate provocations and reduce the possibilities for committing crimes, that is situational crime prevention. Understanding the expected and predictable algorithm of the criminal's actions to commit a crime can be successfully used to develop certain measures that eliminate the possibility of committing a crime and thereby prevent it. Situational crime prevention offers very specific methods of crime prevention that are currently being studied and theorized by progressive criminologists. Particular attention is paid to new theoretical directions in this area, such as identifying the places most susceptible to crime, calculating the algorithm for the actions of criminals and determining the places, routes, the time when criminals gather or carry out their criminal activities. Detailed knowledge of this information gives an idea of where and at what moment police officers can intervene to repress the crime, or take the necessary advance actions to prevent the crime. This method is based on focusing on the place and time of the crime. Crime is never completely random, criminal events and criminal behavior are shaped according to a specific time and place. Thus, the essence of the theory of situational crime prevention is to eliminate provocations, reduce the possibilities of committing crimes and conditions facilitating crimes. Its main purpose is situational crime prevention or security measures.

Authors: Anjana.S  , Mahesh.C.Kundagol  , Devipriya Soman  , James Chacko
Published: October 2021

Purpose: UTI is the broad term used to describe infection of any part of urinary tract and is a problem frequently encountered by health care providers today. E.coli is found to be the main causative agent for causing UTI (80%). The prevalence of UTI are increasing and the present standard of care includes the usage of antibiotics. The alarming and exponential use of nonspecific antibiotics, increased resistance and the high cost of prescribed medications for the management of the infective microorganisms will raise the need for alternate and safe medication. The signs and symptoms of Mutrakruchra and UTI are similar in nature. The combination of Brihatyadi Ksheera Kashaya, Chandraprabhavati and Shweta Parpati is widely practiced in Mutrakruchra. The present study was aimed at exploring the combined effect of the above combination in UTI.

Materials and Methods: The present study was a single group study with pre and post test study design. 20 diagnosed cases of UTI based on ICD10N39.0 diagnostic criteria and proper exclusion were selected from IPD and OPD of Amrita Ayurveda Hospital. They were administered Brihatyadi Ksheera Kashaya, Chadraprabhavati and Shweta Parpati for 15 days.

Result: The obtained data were analyzed statistically with symptoms of UTI, Urine analysis and urine culture by using Wilcoxon signed rank test done on the 0th and 16th day. There was significant change with 100% of improvement in clinical symptoms of UTI after treatment. Statistically significant result was obtained in reduction of WBC with p value 0.001, Epithelial cells with p value 0.005, and Nitrites, Leucocyte esterase, Bacteria with p value 0.0001. There was reduction in growth of E.coli in urine culture with statistically significant p value 0.0001.

On assessing the symptoms, Grahani dushti, Agnimandya, Arsas and Tridosha involvement can be found predominating in the pathophysiology. Kaidaryadi kashayam is a well known traditional decoction formulation from the text Chikitsa manjari- Mahodara chikitsa. This yoga having Tridoshahara, Kleda soshana, Pachana deepana, Vatanulomana and Grahani balya property is found to be effective in reducing the symptoms of IBS, when administered along with suitable formulations. Kaidaryadi kashayam contain 4 drugs i.e., Zingiber officinale, Murraya koeinigii, Terminalia chebula and Tricosanthes dioica. The action of Kaidaryadi kashayam is evaluated for its action on IBS based on available clinical and research data here in this paper. The ingredients inhibits proton pump, thereby reducing the gastric secretion, helps in the protection of gastric mucosa, reduces the acidity of gastric juice and acts as a strong cytoprotective. So based on the available data we can say Kaidaryadi kashayam is an effective formulation in the management of Lower GIT pathology of IBS.

Tongue-coating and mixed saliva obtained from smokers and/or drinkers: nitric oxide/nitrite contents
Authors: Souza Marise Ramos de , Genestra Marcelo
Published: October 2021

The aim of this study was to investigate comparatively the concentration of a nitrogen radical, particularly nitric oxide (NO)/nitrite (NO2 -), in the tongue-coating and mixed saliva obtained from smokers/non-smokers and drinkers/non-drinkers, proving the cytotoxic and cytoprotective effect of these free radicals in oral metabolism and physiophatolology of oral diseases. Masticatory (stimulated) methods were used in order to determine the salivary flow rates of 100 patients. The tongue-coating was obtained through of tongue cleaning named Kolbe’s cleaner. Nitrite contents was measured spectophotometricaly by Griess method. Despite the NO been admittedly an important mediator of some physiological functions, when it is generated in excess it acts as the molecule-key of the cellular damage and tissue injury. The results point out that the association tobacco/alcohol points positive correlation between the increasing concentration of nitrogen radicals in the mixed saliva in order to favour tobacco/alcohol users, in comparison with the control group (not smokers/not drinkers). However, the NO/NO2 - concentration in tongue-coating is worthless, comparing to mixed saliva.

Published: October 2021

A paracoccidioidomicose é uma micose sistêmica. Sua infecção ocorre pela inalação dos conídeos dispersos no ar. É uma patologia que pode acometer todo o organismo humano e contém diversas formas de apresentação. O objetivo deste estudo foi relatar e discutir o caso de um paciente que apresentou a forma infanto-juvenil. Paciente do sexo masculino, 11 anos, HIV negativo, natural de Mendes – RJ, onde foi criado na zona rural até os 7 anos de idade, atualmente reside em Volta Redonda. O adolescente foi admitido no hospital: hipocorado (1+/4), presença de linfoadenopatias generalizadas, hepatoesplenomegalia e iniciou quadro de febre após o terceiro dia de internação. A sorologia de TORCH não nos mostrou resultados importantes. Foi realizada biopsia linfonodal axilar esquerda, cujo resultado histopatológico foi de doença granulomatosa difusa, com imagens fúngicas semelhantes à “roda de leme”, fortificando o diagnóstico de Paracococcidiodomicose. Fez uso de Anfotericina B em ambiente hospitalar e sulfametaxazol com trimetoprim em domicílio. A suspeita dessa enfermidade é facilitada através da associação do caráter endêmico com a história e manifestações clínicas apresentadas pelos pacientes. Esse relato teve como finalidade evidenciar a importância de se elaborar uma anamnese minuciosa, o diagnóstico e o tratamento adequado desta patologia grave e que pode ser fatal.

Authors: Rodrigues William Costa
Published: October 2021

A geração de resíduos sólidos tem crescido ao longo dos anos, principalmente pelo crescimento do consumo e da população. O presente estudo teve como objetivo elucidar o estado da arte do impacto ambiental gerado pela atividade antrópica, além de dimensionar os impactos gerados. O estudo compreendeu o período de estudo entre maio de 204 e março de 2015, sendo realizados três levantamentos em lixeiras espalhadas pelo Campus, para a contagem e segregação dos resíduos por tipo e material de fabricação. Associado a este levantamento foram obtidos os dados de venda de produtos na cantina local, visando a comparação entre estes. Para o dimensionamento dos possíveis impactos gerados pelo Campus foi aplicada a matriz de impacto de Suetênio. Verificou-se que o copo descartável de 180 mL é o resíduo com maior geração, com média de 201 copos/dia, seguido por copos de guaraná natural (25,67/dia). Quando considerado o tipo de material de fabricação verifica-se que os plásticos respondem por 85,35% dos resíduos produzidos, seguido por metais 4,34%. Conclui-se que os impactos gerados pelos Campus poderia ser minimizados com a implantação de um projeto de educação ambiental e a coleta seletiva e destinação correta dos mesmos.
Espécies de Lactobacillus e seu papel na vaginose bacteriana
Authors: Lima Miguel Guzzo , Pereira Carlos Alberto Sanches , Nowak Lara Danielle
Published: October 2021

A vaginose bacteriana representa o distúrbio ginecológico mais prevalente em mulheres com idade reprodutiva e tem como etiologia principal a alteração da microbiota vaginal normal, composta predominantemente por lactobacilos, que inibem o crescimento e a adesão de patógenos fornecendo defesa local. O gênero Lactobacillus contém mais de 80 espécies, em que os predominantes no canal vaginal da mulher em idade reprodutiva são: L. crispatus (30,1%), L. jensenii (26,5%), L. gasseri (22,9%) e L. vaginalis (8,4%), destes o L. crispatus demonstrou ser o maior produtor de acido lático e o melhor protetor contra infecções. Devido as suas características benéficas, o L. crispatus poderia ser utilizado como biomarcador de saúde vaginal e como probiótico. Os lactobacilos vaginais usados como probióticos na recolonização e na manutenção da microbiota vaginal, combinados com antibióticos ou não, podem ser eficientes no tratamento e na prevenção de infecções vaginais. Entretanto é preciso mais estudos para confirmar os benefícios do uso de probióticos no tratamento da vaginose.

Estudos sobre Ferro Fundido têm sido diversamente difundidos com o passar dos anos, devido a seu baixo custo e sua alta aplicação de mercado. Este trabalho tem como objetivo principal a caracterização microestrutural e a análise da Microdureza Vickers no ferro fundido cinzento que se diferenciam pela quantidade de Carbono existente na composição química 2,5 e 4,0% e de silício variam entre 1,0 e 3,0. As amostras foram preparadas metalograficamente, conforme norma ASTM E 407. As análises foram realizadas, utilizando-se os seguintes equipamentos: Microscópio Óptico (MO), Microscópio Eletrônico de Varredura (MEV) e Microdurômetro. Análises em MO mostram a morfologia das amostras, também utilizou-se o MEV para uma melhor visualização da morfologia da microestrutura. Testes de microdureza na escala Vickers foram realizados com duas cargas de indentação, 300 e 500 gf. A dureza por microindentação Vickers da amostra ficou em torno de 230 HV.
Políticas Públicas Como Ferramenta De Equidade Entre (Trans) Gêneros No Mundo Do Trabalho
Authors: Moura Renan Gomes de
Published: October 2021

O presente trabalho consiste em uma revisão teórica sobre as políticas públicas que visam combater o preconceito enfrentados pelos transgêneros ao tentar inserir-se no mercado de trabalho. A intolerância à transsexualidade e a homofobia estão impregnadas em todos os âmbitos sociais.  Nesse sentido é possível perceber que as políticas do mercado são altamente excludentes, onde a sexualidade é tratada como um quesito de diferenciação dos demais trabalhadores indo assim contra princípios constitucionais, fazendo assim a necessidade da elaboração de políticas públicas. O objetivo geral do presente trabalho é verificar como o governo brasileiro vem intervindo no mercado de trabalho através da elaboração de políticas públicas que visam a inserção de transgêneros no mercado de trabalho. A metodologia adotada consiste na revisão bibliográfica sobre a temática proposta. Concluiu-se que as políticas públicas são ineficazes, pois em sua maioria, estas foram propostas pelo Ministério da Saúde e não pelo Ministério do Trabalho e Emprego.

Published: October 2021

A Lei 8069/90, a Lei 12010/09 e o Plano Nacional de Promoção, Proteção e Defesa de Crianças e Adolescentes à Convivência Familiar e Comunitária determinam que o Estado deva assegurar a convivência familiar de crianças e adolescentes, se não for possível em sua família natural, numa família substituta, que pode se constituir pela adoção, para que se evite a institucionalização. A avaliação dos pretendentes à adoção é uma das etapas de preparação psicossocial dos postulantes, prevista no Estatuto da Criança e do Adolescente em seu parágrafo terceiro, artigo 50. A responsabilidade desta etapa do processo é da equipe auxiliar do Juiz, composta por assistente social e psicólogo. E qual o perfil das famílias que desejam a adoção? Não há estudos e pesquisas que caracterizem o perfil do adotante, ao contrário da multiplicidade de informações sobre o perfil de quem pode ser adotado. Este trabalho objetiva apresentar o perfil dos habilitados para adoção no município de Volta Redonda, construído após a análise das fichas cadastrais dos habilitados registrados no Cadastro Nacional de Adoção e da leitura dos relatórios e pareceres profissionais da equipe técnica da Vara da Infância e Juventude da Comarca da Volta Redonda.

Published: October 2021

O estudo dos polímeros e suas propriedades são incentivados pela ampla utilização desses tipos de materiais nos mais diversos setores de atividade econômica. O objetivo desta avaliação foi identificar as propriedades mecânicas das blendas poliméricas com corpos de PEBD/EVA nas proporções 70/30, respectivamente, e 50/50, que foram submetidos à injeção em Injetora, à temperatura de 260ºC, para conformação de CPs a pressão de 70 PSI. Foram preparados 5 (cinco) corpos de prova relativos a cada porcentagem para realização dos ensaios de tração, segundo a norma ASTM D 638-03. Os ensaios de tração e alongamento à ruptura foram realizados no equipamento EMIC DL1000 capacidade de 100KN, com temperatura de ambiente de 22ºC, velocidade de 10 mm/min. Os resultados foram obtidos a partir de 5 (cinco) corpos de prova na forma de gravatas. No ensaio de tração usaram-se corpos de prova de 60 mm. A microscopia óptica (MO) foi realizada em microscópio óptico marca OPTON objetivas 10, 20 e 40X e a microscopia eletrônica em microscópio eletrônico de varredura (MEV) marca HITACHI TM3000, com elétrons secundários. Através do estudo de microscopia óptica e MEV, observou-se uma estrutura de duas fases, onde, partículas de copolímero EVA estão dispersas na matriz de PEBD. Do ponto de vista das propriedades mecânicas, concluiu-se que a incorporação de copolímero de EVA em uma matriz de PEBD tem um impacto significativo para o melhoramento de sua flexibilidade. A resistência a tração diminui, enquanto que a ductilidade e a tenacidade aumentam.
