Discursos dos cursos da área da saúde sobre gênero e biotecnologias no âmbito da formação / Discursos de los cursos de salud sobre género y biotecnologías en el contexto de la formación / Discourses of health courses on gender and biotechnologies in the context of training

RESUMO Objetivo: investigar os discursos sobre gênero e biotecnologias no âmbito da formação dos cursos da área da saúde. Metodologia: trata-se de uma pesquisa qualitativa exploratória descritiva que está alicerçada em um estudo maior - projeto de pesquisa - desenvolvido pelo Grupo de Estudos e Pesquisas em Saúde (GEPS), intitulado "Gênero e Biotecnologias: Interfaces entre discursos e instituições na formação de alunos dos cursos da área da saúde". A pesquisa ocorreu entre os meses de março e outubro de 2019, sendo realizada por meio de entrevistas semiestruturadas com estudantes brasileiros e espanhóis da área da saúde, gravadas em áudio e transcritas para Análise do Discurso. Resultados e Discussão: os achados indicam que Gênero e Biotecnologia são temáticas que não subsidiam as discussões da formação de futuros profissionais da saúde, mostrando um entendimento de gênero centrado numa norma binária, não havendo espaço para outras possibilidades identitárias, além de a heterossexualidade ser vista como padrão de comportamento a ser seguido. Percebe-se uma certa complexidade na formulação dos discursos dos estudantes no que se refere aos aspectos em que gênero e biotecnologias escapam da relação entre corpo biológico e utilização tecnológica para esses enquadramentos físicos e mentais. Considerações Finais: as discussões sobre gênero e biotecnologias nas universidades estudadas têm sido realizadas de forma isolada, sendo necessária uma reestruturação de seus currículos de modo que os temas apresentados passem a ser contemplados para que, efetivamente, componham a formação equitativa e integral de profissionais.

RESUMEN Objetivo: investigar los discursos sobre género y biotecnologías en el contexto de la formación de los cursos de salud. Metodología: se trata de una investigación exploratoria descriptiva cualitativa que se basa en un estudio más amplio -proyecto de investigación- desarrollado por el Grupo de Estudios e Investigación en Salud (GEPS), titulado: "Género y Biotecnologías: Interfaces entre discursos e instituciones en la formación de estudiantes de cursos de salud", que se produjo entre los meses de marzo y octubre de 2019 a través de entrevistas semiestructuradas, con estudiantes de salud brasileños y españoles, grabadas en audio y transcritas para el Análisis del Discurso. Resultados y discusión: los hallazgos indican que el Género y la Biotecnología son temas que no subsidian las discusiones de la formación de los futuros profesionales de la salud, mostrando una comprensión del género centrada en una norma binaria en la que no hay espacio para otras posibilidades de identidad y la heterosexualidad como norma de comportamiento a seguir. Se percibe cierta complejidad en la formulación de los discursos de los estudiantes, en cuanto a los aspectos en los que el género y las biotecnologías escapan de la relación entre el cuerpo biológico y el uso de la tecnología para estos marcos físicos y mentales. Consideraciones finales: las discusiones sobre género y biotecnologías en las universidades brasileñas y españolas se han llevado a cabo de forma aislada, y es necesario reestructurar estos planes de estudio para que los temas presentados puedan ser contemplados en los planes de estudio para que efectivamente compongan la formación equitativa e integral de los profesionales.

ABSTRACT Objective: to investigate the discourses on gender and biotechnologies within the training of health courses. Methodology: this is a qualitative, exploratory, and descriptive study that is based on a larger study - a research project - developed by the Studies and Research Group in Health (GEPS), entitled "Gender and Biotechnologies: Interfaces between discourses and institutions in the training of students from health courses." The research took place between March and October 2019 and was carried out through semi-structured interviews with Brazilian and Spanish health students, audio-recorded, and transcribed for Discourse Analysis. Results and Discussion: the findings indicate that Gender and Biotechnology are themes that do not subsidize the discussions of the training of future health professionals, showing an understanding of gender centered on a binary norm, with no space for other identity possibilities besides heterosexuality being seen as a standard of behavior to be followed. A certain complexity is perceived in the formulation of the students' speeches regarding the aspects in which gender and biotechnologies escape from the relationship between the biological body and the technological use for these physical and mental frameworks. Final Considerations: the discussions about gender and biotechnologies in the studied universities have been carried out in an isolated way, making it necessary to restructure their curricula so that the themes presented can be contemplated to effectively compose the equitable and integral formation of professionals.

All-around management of a fungal isolate obtained from cheese spoilage as an environmental source: Direct approach from an undergrad student to a biotechnological characterization.

In this work, we present the results of an undergrad student from the perspective of its first approach as a principal researcher in a project. In order to gain practical experience, one of the options for students that have interest in pursuing a postgraduate program corresponds to a research stay in a laboratory of their selected field conducting a project for a period of 6 months. In this particular project, a fungal sample was isolated from Parmesan cheese spoilage and its enzymatic activity evaluated. Using simple and standardized protocols, the student was capable of identifying a possible biotechnological application for the isolate by detecting and categorizing the lipolytic activity. Through microculture characterization in potato dextrose agar (PDA) the genus of the sample was determined as Penicillium and confirmed by molecular analysis of the ITS1 and ITS4 regions. In order to examine comprehensively the potential of the new isolate, the extracellular and intracellular enzymatic activities were analyzed as well as four methods of cell rupture. From these results, sonication was determined as the best technique with 211 U/L as a maximum lipolytic value. To finalize the evaluation of the sample, the student determined the optimal pH and temperature as well as the thermotolerance of the crude extract obtaining a residual activity of 13% after 60 minutes of incubation at 45 °C. Upon conclusion of the research we could recognize that through a direct characterization of a fungal isolate using techniques that are widely known, the student was capable of determining and value one of the most interesting capabilities fungi has to offer; enzymatic activity, and that the knowledge obtained from established protocols enables and encourages the students to correlate the source from where they were obtained with potential biotechnological applications. © 2019 International Union of Biochemistry and Molecular Biology, 47(6):681-688, 2019.

Invisible signals from the underground: A practical method to investigate the effect of microbial volatile organic compounds emitted by rhizobacteria on plant growth.

Rhizobacteria that colonize plant roots and promote plant growth are referred to as plant growth-promoting rhizobacteria, and this can stimulate plant growth either indirectly or directly. Volatile organic compounds (VOCs) emitted by rhizobacteria have the capacity to promote plant growth as well as perform biocontrol of fungal pathogens. The microbial volatile organic compounds (mVOCs) are characterized by a low molecular weight and a high vapor pressure, which facilitate evaporation and diffusion at normal temperatures and at above-ground and below-ground pressures. mVOCs can travel far from the point of production through the atmosphere, porous soils and liquids, thereby making them ideal infochemicals for mediating interspecific interactions. However, knowledge about the biological and ecological roles of microbial VOCs is still limited compared with that of plant VOCs. Here, we describe a simple and inexpensive laboratory class aimed at biotechnology or soil microbiology students, which uses techniques to increase their understanding of the mechanisms of plant growth promoting rhizobacteria and also illustrate the effects of mVOCs emitted by rhizobacteria on plant growth promotion, as well as evaluating their potential as a biocontrol. The laboratory class is divided into two sessions: an initial 3-hour experimental session and a second 2-hour analytical one. The experimental session involves two separate experiments: one of which is dedicated to illustrating the effect of mVOCs on plant growth parameters, while the second explores the capacity of VOCs as a biocontrol. Also, the class provides students with an opportunity to perform useful assays, draw conclusions from their results, and discuss possible extensions of the study. © 2019 International Union of Biochemistry and Molecular Biology, 47(4):388-393, 2019.

Basic-education mexican teachers' knowledge of biotechnology and attitudes about the consumption of genetically modified foods.

Over the past few years, a new research field has emerged, focusing on the social-scientific criteria for the study of opinions toward genetically modified foods (GMFs), since these may be limiting factors for the success or failure of these products. Basic education is the first step in the Mexican education system, and teachers may wield an outsized influence on the attitudes and preferences of children, prospective future consumers of these products. To better understand the current state of knowledge of biotechnology issues and opinions toward the consumption of GMF of Mexican teachers, a questionnaire was distributed, and 362 Mexican teachers of basic education responded. The survey included questions about the benefits and risks of consuming GMF. The mean percentage of teachers expressing knowledge of a given topic in biotechnology was 50%. More than 60% of teachers believed that GMFs would be useful in preventing world hunger, while 39.2% considered GMF to be hazards for future generations. Although 47.0% reported not having enough knowledge about these topics, almost all (90.3%) respondents expressed an interest and willingness to learn about biotechnology. In light of the fact that teachers of basic education represent the first and potentially most lasting stage in the education of young children, this survey establishes the urgent need to develop strategies to improve the scientific knowledge of teachers and to facilitate decision making and the promotion of scientific and technological advances for their students. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(5):396-402, 2017.

A practical teaching course in directed protein evolution using the green fluorescent protein as a model.

Protein engineering is a powerful tool, which correlates protein structure with specific functions, both in applied biotechnology and in basic research. Here, we present a practical teaching course for engineering the green fluorescent protein (GFP) from Aequorea victoria by a random mutagenesis strategy using error-prone polymerase chain reaction. Screening of bacterial colonies transformed with random mutant libraries identified GFP variants with increased fluorescence yields. Mapping the three-dimensional structure of these mutants demonstrated how alterations in structural features such as the environment around the fluorophore and properties of the protein surface can influence functional properties such as the intensity of fluorescence and protein solubility.

Accommodating the difference in students' prior knowledge of cell growth kinetics

This paper describes the development and benefits of an adaptive digital module on cell growth to tackle the problem of educating a heterogeneous group of students at the beginning of an undergraduate course on process engineering. Aim of the digital module is to provide students with the minimal level of knowledge on cell growth kinetics they need to comprehend the content knowledge of the subsequent lectures and pass the exam. The module was organised to offer the subject matter in a differentiated manner, so that students could follow different learning paths. Two student groups were investigated, one consisting of students who had received their prior education abroad and one of students that had not. Exam scores, questionnaires, and logged user data of the two student groups were analysed to discover whether the digital module had the intended effect. The results indicate that students did indeed follow different learning paths. Also, the differences in exam scores between the two student groups that was present before the introduction of the digital module was found to have decreased afterwards. In general, students appreciated the use of the material regardless of their prior education. We therefore conclude that the use of adaptive digital learning material is a possible way to solve the problem of differences in prior education of students entering a course.

Educação em biossegurança e bioética: articulação necessária em biotecnologia / Education on biosafety and bioethics: necessary articulation in biotechnology

A educação científica tem sido debatida em alguns segmentos da sociedade e organizações internacionais têm estimulado as nações a investirem nessa área tão estratégica. Nesse contexto, a educação em biossegurança e bioética explora um conteúdo rico em prevenção, normas e princípios éticos, que servem para nortear os caminhos trilhados pela biotecnologia. A valorização da biossegurança e da bioética como parte de uma política educacional científica, efetiva e consistente, pode estimular a formação de indivíduos com uma consciência científica e cidadã, em condições de participar das questões de natureza ética e tecnológica produzidas pela biotecnologia.

Science education has been discussed in some segments of the society and, international organizations have encouraged nations to invest in this strategic area. In this context, education in bioethics and biosafety explores a rich content on prevention, standards and ethical principles which serve to guide the paths track by biotechnology. The recovery of bioethics and biosafety, as part of an educational policy scientific, effective and consistent, can stimulate the formation of individuals with a scientific and citizen awareness, in a position to participate on ethical and technological issues produced by biotechnology.

The relationship among knowledge of, attitudes toward and acceptance of genetically modified organisms (GMOs) among Slovenian teachers / La relación entre el conocimiento y actitudes en la aceptación sobre organismos genéticamente modificados (OGM) entre profesores eslovenos

The objective of this study was to investigate knowledge about, opinions on and attitudes toward and finally readiness to accept genetically modified organisms (GMO) among Slovenian teachers. On average, they have higher levels of knowledge in classical genetics, and poor levels of knowledge about modern issues in biotechnology, and their attitudes toward GMOs are not extreme. They make decisions based on the acceptability of a particular GMO and not on GMOs in general, following two patterns: genetic modifications (GM) microorganisms and plants are more acceptable than animals, and GMOs are more acceptable if they can not be used directly for consumption and produce something recognized as useful. The relationship among knowledge of, attitudes towards and readiness to accept GMO showed that there is no correlation between knowledge and attitudes, only a weak correlation between knowledge and acceptance, and a solid correlation between attitudes and readiness to accept GMO. The practical implication of our findings is that acceptance of GMOs will not be changed by providing new technical or scientific information to teachers but by changing attitudes. The appropriate strategies and actions for improving university courses in biotechnology and the implication for classroom science activities and future research are discussed.

Biosafety education relevant to genetically engineered crops for academic and non-academic stakeholders in East Africa

Development and deployment of genetically engineered crops requires effective environmental and food safety assessment capacity. In-country expertise is needed to make locally appropriate decisions. In April 2007, biosafety and biotechnology scientists, regulators, educators, and communicators from Kenya, Tanzania, and Uganda, met to examine the status and needs of biosafety training and educational programs in East Africa. Workshop participants emphasized the importance of developing biosafety capacity within their countries and regionally. Key recommendations included identification of key biosafety curricular components for university students; collaboration among institutions and countries; development of informational materials for non-academic stakeholders and media; and organization of study tours for decision makers. It was emphasized that biosafety knowledge is important for all aspects of environmental health, food safety, and human and animal hygiene. Thus, development of biosafety expertise, policies and procedures can be a stepping stone to facilitate improved biosafety for all aspects of society and the environment.

Food biotechnology and education

It is clear that the future of our children will be marked by the development of two scientific disciplines: computing and biotechnology. Regarding the first, during recent years considerable progress have been done in many countries around the globe aimed at enhancing the teaching in these subjects and, at the same time, encouraging the use of computers in classrooms. On the contrary, training in biotechnology is absent in many secondary schools of the planet. This formative deficiency generates citizens whose opinion on the marketing of biotechnological products is easily manipulated by both defenders and opposers of biotechnology. This situation is of particular relevance when the item in question is food biotechnological applications that provoke an intense social debate and more specifically the so-called genetically modified foods (GM foods). In this article we report a survey carried out with 500 young Spanish consumers in order to discover their attitudes to GM foods. The work has been focused on the study of the perception of GM foods and their labelling. The results indicate that they are moderately receptive to GM foods but like to be informed through labelling. However, the most important conclusion of the survey is the lack of sufficient knowledge about food biotechnology and genetic engineering on the part of young Spaniards. It is therefore very important that an unbiased presentation of the scientific basis of biotechnology should be introduced in secondary education. In this sense, the project BIOEDUCAR is an important tool to introduce unbiased information about food biotechnology in the Latin America and Spanish secondary schools.

A practical approach to the understanding and teaching of RNA silencing in plants

Gene silencing, also called RNA interference (RNAi) is a specific mechanism of RNA degradation involved in gene regulation, development and defense in eukaryotic organisms. It became an important subject in the teaching programs of molecular biology, genetics and biotechnology courses in the last years. The aim of this work is to provide simple and inexpensive assays to understand and teach gene silencing using plants as model systems. The use of transient and permanent transgenic plants for expressing reporter genes, like those derived from jellyfish green fluorescent protein (gfp) encoding gene, provides a nice, colorful and conclusive image of gene silencing. Three experimental approaches to evidence RNA silencing are depicted. In the first approach gene silencing is demonstrated after transient expression of reporter genes in non-transgenic plants. In the second, silencing is triggered against a reporter gene stably integrated into a transgenic plant. The third approach involves the triggering of RNA silencing against endogenous genes using viral vectors. In addition we illustrate systemic gene silencing showing how the silencing signal is spread over a plant and finally it is also demonstrated the suppression of gene silencing. The first group of experiments is recommended to be tough on undergraduate courses, the following two sections are recommended for graduate courses. Hopefully, it will help students to understand this important phenomenon and to unravel the importance of gene silencing as a key gene regulation mechanism and as a molecular and biotechnological tool.

A nationwide biotechnology outreach and awareness program for Malaysian high schools

Biotechnology education in developing nations remains one of the rate limiting factors in achieving optimal human resource capacity to drive and tap the bio-resources of these nations. Many developing countries are situated within rich bio-diversity enclaves. Biotechnology offers the promise of tapping these bio resources towards due process of developing these nations. While there may be a steady stream of biology and biotechnology based graduates, from Malaysian as well as foreign universities contributing to the human resource base for these countries, the numbers and knowledge diversity produced, still lack the capacity to optimally power research and development as well as supply the industrial biotechnology sectors of these countries. Realizing the need to address these issues at the grassroots level of higher education, Malaysia has taken an active step of bringing biotechnology into the classrooms of high schools throughout the country. These future generations of Malaysians, are hoped to progress towards manning and driving Malaysia's BioValley initiatives (a biotech based R&D and industry cluster), towards the national dream of developed nation status by the year 2020, using biotechnology as an economic growth vehicle. Here, we share our experiences in developing and proliferating a biotechnology awareness program for Malaysian high schools. It is hoped that similar programs will strive towards similar objectives in other developing countries.
