Wybrane problemy i dylematy etyczne w badaniach z udziałem rodziców dzieci z zespołem Aspergera
Authors: Całek Grzegorz
Published: November 2020

Artykuł jest zbiorem refleksji etycznych wynikających z doświadczeń autora w prowadzeniu badań z udziałem rodziców dzieci z zespołem Aspergera. Punktem odniesienia dla tych rozważań są wybrane zapisy zawarte w „Kodeksie etyki socjologa”, w części dotyczącej relacji z uczestnikami badań. W szczególności zostały przeanalizowane problemy etyczne związane z relacjami pomiędzy badaczem a osobami badanymi: Gdzie przebiega granica pomiędzy rolą badacza a innymi możliwymi rolami (np. konsultanta, osoby wspierającej, terapeuty)? Czy można wykroczyć poza rolę badacza? Wskazano także na trudności związane z przestrzeganiem zasady mówiącej, że prowadzone badania nie mogą mieć negatywnego wpływu na stan ich uczestników: Czy takie badania powinni prowadzić jedynie socjologowie będący jednocześnie psychologami czy terapeutami, a więc osoby profesjonalnie przygotowane na niespodziewane reakcje osób doświadczonych trudnymi do wyobrażenia problemami codzienności życia z dzieckiem z niepełnosprawnością? Czy jest możliwe przygotowanie się na takie niespodziewane sytuacje w rozmowie z rodzicami dzieci z zespołem Aspergera? W artykule pokazano, że na te pytania nie ma jednoznacznej odpowiedzi.

The work presents the results of soil and environmental studies on the Bolshoy Solovetsky Island. The main environmental problems in this territory include the presence and operation of production facilities, discharge of untreated water into the White Sea bays, and non-compliance with the established requirements for the storage of municipal solid waste. In order to assess the anthropogenic impact on soils, 44 samples were taken in the summer of 2016-2017. The study included the determination of both physico-chemical and biological indicators. During the study, the differentiation of the soil profile by granulometric composition was revealed: the upper part is heavier and the lower part is lighter, which affected the change in all indicators. A slightly acidic environment has been established for the soils of the studied areas. The average pH of water for all studied samples was 5.7, varying down the profile from the surface from 4.4 to 5.9. The average organic matter content for all samples was 10 %. Its content in the coarse-humus horizon varied from 20 to 36 %, in the eluvial horizon it decreased to 2-3 %, and in the lower horizons of sandy horizons with various inclusions – up to 1 % and lower. The obtained indicators of the content of heavy metals (HM) and petroleum products (РP) were correlated with the accepted pollution levels. Soils in separate trial areas of TM, primarily zinc and lead, as well as petroleum products. The data obtained showed the presence of influence on the soil of three structures - a gas station and a diesel power station, a dry dock. The average value of catalase activity for all studied soil samples from the Solovetsky village amounted to 10.6±0.3 in the surface horizon of the control soil sample was 19±1 mg H2O2 for 1 hour per 3 g of soil. Eliminating the influence of natural abiotic factors, an increase in enzyme activity to 29 units relative to the control sample in soil with a high content of HM (about 10,000 μg/kg) and a sharp (up to 3 units) decrease in activity in soil with a high level of pollution of РP (13400 μg/kg). According to the results of soil research Solovetsky village showed a very high level of contamination at some PPs and a reliable response to this effect of catalase activity. It has been suggested that it is possible to use the activity of this enzyme as a diagnostic indicator of soil contamination in the Solovetsky village with the above pollutants.

O objetivo deste estudo foi avaliar o desempenho produtivo, histomorfometria intestinal e composição corporal de juvenis de jundiá alimentados com dietas contendo níveis crescentes de inclusão (0, 25, 50, 75 e 100%) de farelo de canola (FC) em substituição ao farelo de soja (FS), suplementadas ou não com a enzima fitase (0 e 1500 UFA/kg-1). Grupos de 10 peixes foram distribuídos aleatoriamente em 30 unidades experimentais e alimentados com suas respectivas dietas experimentais por 60 dias. Houve interação significativa entre os fatores para o ganho em peso (GP), conversão alimentar aparente (CAA) e taxa de eficiência proteica (TEP). Para o GP, os maiores resultados foram evidenciados nos jundiás alimentados com dietas contendo 100% de FC, sem fitase, e 75% de FC, com fitase. Na CAA, os melhores resultados foram verificados nos peixes alimentados com 50, 75 e 100% de inclusão de FC, independente da suplementação da enzima. A TEP foi maior nos peixes alimentados com 50% de FC, sem fitase. Houve influência da substituição de FS por FC para a taxa de crescimento específico (TCE), altura das dobras intestinais e matéria mineral corporal (MM). A maior TCE foi verificada nos peixes alimentados com 100% de substituição. A maior altura das dobras intestinais foi observada nos peixes alimentados com 75% de FC na dieta e a maior MM foi verificada nos peixes alimentados com dietas sem a inclusão de FC. O FC pode substituir o FS em dietas para juvenis de jundiá, contudo, sugerimos novos estudos para compreender a utilização combinada de fitase e FC em dietas para esta espécie.

A raiva é uma doença viral gravíssima que pode afetar todos os mamíferos. Trata-se de um estudo exploratório descritivo documental desenvolvido a partir dos dados do Centro de Controle de Zoonoses do município de Niterói, RJ.  No mês de julho de 2018 ocorreram três casos de raiva em morcegos, diagnosticados por imunofluorescência direta e inoculação em camundongos, todos envolvendo Artibeus sp. e localizados numa pequena área do bairro São Francisco. O Centro de Controle de Zoonoses desenvolveu uma série de ações visando impedir a transmissão da doença para humanos e outras espécies de animais. Os resultados sugerem um possível surto de raiva em morcegos no bairro São Francisco, em julho de 2018. A ocorrência de um evento desse em um bairro da área urbana de uma metrópole pode ser considerado um fator preocupante pela possibilidade de ocorrência de casos da doença em humanos ou animais domésticos, principalmente tendo em vista a existência dos demais fatores condicionantes e determinantes da ocorrência da enfermidade encontrados no município. Nesse sentido, esforços devem ser envidados pelo poder público no sentido de eliminar ou mitigar tais fatores, visando salvaguardar a saúde da população.

Published: November 2020

Criptococose é uma doença multissistêmica que acomete humanos e animais. É transmitida pela inalação de esporos de um fungo da espécie Cryptococcus neoformans que se desenvolve em matéria orgânica, principalmente em fezes de aves e madeira em decomposição. Esta enfermidade é, em geral, de caráter oportunista sendo mais comum em gatos do que em cães. As manifestações clínicas dessa doença variam e podem causar distúrbios oftálmicos, respiratórios, cutâneos e neurológicos. O diagnóstico vai além da avaliação física e anamnese, podendo o médico veterinário solicitar exames micológicos (cultura fúngica e esfregaço de material da lesão), citológicos, histopatológicos, entre outros para especificar qual realmente é a causa do problema e tratar de modo mais adequado possível. O tratamento é baseado no uso de antifúngicos sistêmicos, no entanto, a literatura não relata o tempo mínimo adequado de tratamento, indicando manter o protocolo terapêutico por mais 30 ou 60 dias após melhora do quadro clínico e resultados de exames negativos para criptococose. O presente trabalho tem o objetivo de relatar um caso de criptococose cutânea em uma cadela de nove anos da raça Pastor Alemão. A paciente apresentava lesões ulcerativas no membro torácico esquerdo, que causavam dor quando palpadas. O diagnóstico foi confirmado por cultura fúngica e a terapia foi realizada com itraconazol na dose de 10mg/kg, via oral (VO),  a cada 24h (q24h) inicialmente, fazendo ajustes posteriores para 20mg/kg VO, q24h totalizando cinco meses de terapia, resultando em melhora da doença e sem efeitos adversos, para a paciente relatada. Assim, é necessário que exames complementares e diagnósticos mais precisos sejam realizados para contribuírem para uma terapia adequada objetivando a cura clínica.

من أجل تمييز المنتجات والخدمات بعضها عن بعض وضمان عدم وقوع المستهلك أو المشتري في الخلط بينها، لجأت الشركات إلى ابتكار علامات تجارية للترويج لمنتجاتها حتى لا تكون عرضة للتقليد، وتضمن بمقتضاها جذب العملاء وإتاحة فرصة الاختيار والمفاضلة بين المنتجات والخدمات المشابهة والمماثلة المعروضة في السوق. ونظرًا للأهمية التي تكتسبها العلامة التجارية، لكونها وسيلة للتعبير عن ذاتية المنتج أو الخدمة الموضوعة عليها ونسبتها إلى مالكها، كان لا بد أن تحاط بجملة من الضمانات القانونية من أجل حمايتها حتى لا تكون عرضة للتقليد أو التزوير.وتبعًا لذلك تسعى الدراسة إلى الوقوف على آليات الحماية القانونية المقررة للعلامة التجارية في التشريعين الجزائري والسعودي، لمعرفة مدى التشابه بينهما. وقد تمخضت الدراسة على أن المشرعين الجزائري والسعودي سلكا موقفًا إيجابيًا بإقرارهما للحماية الجنائية للعلامة التجارية، وتوقيعهما لعقوبات رادعة يحققان بمقتضاها الغرض من العقوبة، ومن جهة أخرى يعاب عليهما أنهما ربطا الحماية بإجراء شكلي وهو إيداع العلامة أو تسجيلها كشرط لحمايتها. ومن أجل ذلك، توصي الدراسة بضرورة إعادة النظر في شروط الحماية المقررة للعلامة التجارية، فلا يعقل أن يحرم صاحب الحق من حقه لمجرد عدم قيامه بإجراء شكلي.
Molecular Depiction of Thirteen Indian Toxic Plants with ITS Markers
Authors: Kumari Kiran , Bhargava Saurabh , Singh Rajvinder
Published: November 2020

Plant identification is an overwhelming task due to different biological attributes and great diversity in plant species. In the absence of physical markers, molecular techniques have become useful for the identification of species of origin of medicinal plant seeds, pastes, and formulations of suspected plants.
The ITS region of nuclear rRNA was amplified from thirteen different toxic plant species by using universal primer ITS 1 & 4. Nucleotide sequences of all selected plants were submitted in NCBI and accession numbers were acquired.
The results of this study give accurate identification of thirteen plant species and proved the ITS region of 18s-26s nuclear ribosome to be an important tool for phylogenetic analysis and species identification of plants. The sequence was aligned with top matched reference sequence and presented in Clustal Omega software for making a phylogenetic neighbour tree.
The significance of these findings is paramount in forensic toxicology scenarios especially when fragmentary plant material is found in the stomach/intestine and its morphological identification becomes impossible. In these circumstances, the PCR based molecular technique surely plays a significant role in solving complicated forensic cases.

Merebaknya strain M. tuberculoisis yang resisten terhadap obat anti tuberkulosis membuat penanganan TB menjadi semakin sulit dan beban ekonomi yang tinggi. Tujuan dari penulisan paper gagasan tulis ini untuk mendeskripsikan potensi nanopartikel alginat-kitosan-ekstrak daun kedondong hutan sebagai penatalaksanaan TB dan MDR-TB. Dari 87 jurnal yang ditelaah, 50 jurnal ditemukan sesuai dengan topik bahasan dan digunakan sebagai referensi karya ini. Kombinasi penyalutan alginat-kitosan merupakan kombinasi yang paling tepat karena dapat meningkatkan bioavailabilitas dan pelepasan berkelanjutan dari obat antibakteri. Nanopartikel alginat-kitosan-ekstrak daun kedondong hutan dapat menghambat sintesis asam mikolat  M. tuberculosis, proteasom dan mengakibatkan lisis dinding sel M. tuberculosis. Ekstrak daun kedondong hutan mengandung senyawa flavonoid dan triterpenoid yang berfungsi sebagai antituberkulosis. Flavonoid dapat berikatan dengan situs aktif HadB sehingga menghambat aktivitas enzim β-hydroxyacyl-ACP dehydratase yang berfungsi dalam elongasi rantai meromycolic. Selain itu, flavonoid dapat menghambat proteasom M. tuberculosis yang dalam keadaan dorman. Triterpenoid memiliki gugus sehingga mampu mengakibatkan lisis dinding sel M. tuberculsosis. Nanopartikel alginat-kitosan-ekstrak daun kedondong hutan memiliki potensi sebagai terapi baru untuk TB dan MDR-TB. Belum terdapat penelitian mengenai kombinasi modalitas ini sehingga diperlukan penelitian lebih lanjut untuk mengetahui potensi pasti nanopartikel alginat-kitosan-ekstrak daun kedondong hutan.

The establishment of English medium instruction (EMI) brings opportunities for non-native English speaking institutions to compete with Anglophone universities and attract international students to join their program. More policies were designed to improve the academic environment quality and attract international students. As a thesis becomes the graduation requirement, there is a weight of difficulties and high expectations to produce good writing. This study explores thesis writing problems and strategies perceived by L2 writers as international graduate students in Taiwanese EMI classrooms in Taiwan. The participants were 152 international students who pursued a graduate degree in Taiwanese tertiary education; their major was categorized into engineering and social studies. The data was collected through questionnaires and in-depth interviews with some participants. The quantitative result indicates both students across the major were experiencing the same challenges in thesis writing and utilizing similar strategies to overcome the problem. Later, the qualitative result provides explanations to what really happen among these graduate students while writing thesis. The result serves reference and suggestion for academics in assisting their supervisee. It also suggests to the university to assist these L2 writers by providing writing correction services to the betterment of the EMI programs in their institution.

Authors: Guibangguibang Herford Rei Biscayno
Published: November 2020

This study sought to answer the question on the level of English language anxiety in the ESL and mainstream classrooms of 61 total number of English major students utilizing the 20-item self-assessment questionnaire of English Language Anxiety Scale (ELAS) developed by Pappamihiel (2002). Actual one-hour footage of classroom was documented through a MONACORR audio-recorder, thrice with each teacher. The recorder was given to one of the teachersâ€™ students without knowledge for the authenticity of their oral corrections. After having identified the existing oral error corrections by the English teachers through audio-recording, a self-made questionnaire was answered by the students to find what is the rate of occurrence of the identified oral error correction styles. The frequency count, weighted mean, and Chi-square tests were the statistical tools used to answer the problems posed in this study. Findings divulged after the transcription, teachers were only utilizing elicitation, explicit correction, recast, and repetition. Moreover, students perceived that elicitation oral error correction type is often used while explicit correction, recast, and repetition are only used sometimes by their English teachers.Â  Meanwhile, ELAS results indicate levels of language anxiety in the ESL classes and mainstream, although language anxiety is significantly higher in ESL classes. As to correlation, it was found out that the rate of occurrence of explicit correction, recast, and repetition as perceived by ESL English major students of their English teachersâ€™ oral error correction types have no significant relationships to their English language anxiety. This study suggests that oral error correction has nothing to do with the English language anxiety of English major students and that English teachers shall retain the practice of the oral error correction for it does not give high level of learnersâ€™ anxiety in learning English.Â
