Active Methodologies in Teaching Human Anatomy: An Integrative Review
Human anatomy is one of the fundamental disciplines for the training of health professionals, especially in the medical field. Its didactic origin is based on the European school where the body was dissected in amphitheaters and anatomical knowledge was transmitted from the teacher to his students. With the restructuring of medical curricula, and the use of active methodologies, seeking to make the student the center of the learning process, anatomy started to be taught in another way. This study carries out an integrative review in the Scielo, Science Direct and Google Scholar databases, from 2015 to 2020, about the active methodologies used in the teaching of human anatomy for the medical course. The PICo strategy was used to form the guiding question and the results were presented through the Prisma Flow diagram. It was found that there are a number of tools and strategies that can be used aiming at the active teaching of human anatomy, however, a common point observed in most works is the approach of joint use with cadavers and anatomical parts, thus seeking to stimulate the development of the skills and competences of medical students
Diversity, chemical constituents and biological activities of endophytic fungi isolated from Schinus terebinthifolius raddi
Schinus terebinthifolius Raddi is a medicinal plant widely used for the treatment of
various diseases. The secondary metabolites responsible for the pharmacological properties can
be produced directly by the plant or by endophytic fungi. The objective of this study was to
evaluate the diversity of endophytic fungi of di erent parts of S. terebinthifolius and to identify
chemical compounds produced by endophytes and their antioxidant and antibacterial activities.
For this, fruits, stem bark and roots were dried, ground and placed in fungal growth medium.
The selected endophytes were grown and subjected to extraction with ethyl acetate. DPPH, FRAP,
-carotene bleaching and antimicrobial assays were performed. The phylogenetic tree was elaborated,
encompassing 15 di erent species. The fungal extracts showed hydroxybenzoic acids and 1-dodecanol
as predominant compounds. All fungal extracts exhibited antioxidant activity. The fungal extracts
exhibited bactericidal and bacteriostatic activities against Gram-positive and Gram-negative bacterial
ATCC strains and against methicillin-resistant nosocomial bacteria. Among the 10 endophytic
fungi evaluated, the extract of the fungus Ochrocladosporium elatum showed higher phenolic content
and exhibited higher antioxidant and antibacterial activities in all tests. Together, the results increase
the known diversity of S. terebinthifolius endophytic fungi, secondary metabolites produced and their
antioxidant and antibacterial activities.Thisworkwas supported by grants fromFoundation to Support to Fundação deApoio aoDesenvolvimento do Ensino, Ciência e Tecnologia do Estado deMato Grosso do Sul (FUNDECT), Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), and Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq).info:eu-repo/semantics/publishedVersio
Beyond the “resprout or not resprout” dichotomy: on the prevalence and evolutionary fingerprint of resprouting in tropical dry forest trees
Conservation of wild mushrooms through electron beam irradiation
The high perishability is a characteristic of the mushrooms consumed in fresh. Therefore, it is mandatory the application of effective conservation technologies to preserve and protect their chemical composition and nutritional value. Drying processes are widely used, but do not avoid the development of bacteria and fungi which have the ability to survive for long periods of time in dry foods, causing the loss of some nutrients and leading to food browning and oxidation of lipids and vitamins [1]. Irradiation appears as an alternative to food preservation assuring and maintaining its quality [2]. In this work, the effects of electron beam irradiation and storage time on nutritional and chemical parameters of wild samples of Macrolepiota procera (Scop.) Singer, previously submitted to a drying process (oven at 30 ºC), were assessed. The wild mushroom samples were collected in Trás-os-Montes; electron beam irradiation (doses 0.5, 1 and 6 kGy) was carried out in the INCT- Institute of Nuclear Chemistry and Technology in Warsaw, Poland and the analyses were performed over the storage period (0, 6 and 12 months). The results were compared with a control (non-irradiated samples). The nutritional value was determined according to the official procedures of food analysis, while the profiles of fatty acids, tocopherols, mono and oligosaccharides were obtained by chromatographic techniques [1]. The irradiation showed a better capacity to maintain the nutritional and chemical profile, in comparison with the storage time. Effectively, the storage time had a significant effect in all parameters, but fatty acids undergone significant changes both with irradiation doses and storage time. Electron beam irradiation can be considered a suitable technique for conservation of mushrooms for long periods of time, attenuating the changes caused by the drying treatment.The authors are grateful to the Foundation for Science and Technology (FCT, Portugal) and FEDER under Programme PT2020 for financial support to CIMO (UID/AGR/00690/2013), A.

Microbiological quality, chemical profile as well as antioxidant and antidiabetic activities of Schinus terebinthifolius Raddi
Schinus terebinthifolius Raddi, commonly known as Brazilian peppertree, is a plant species widely used in Brazilian traditional medicine for various purposes. The objective of this study was to assess the microbiological quality, safety, chemical profile as well as antioxidant and antidiabetic potentials of different parts of S. terebinthifolius. Microbiological analysis of the methanolic extracts of the roots (MESR), stem bark (MESB) and leaves (MESL) of S. terebinthifolius showed no microbial growth. The concentrations of phenolic compounds, phenolic acids and flavonoids were determined by spectrophotometry. The phenolic compounds of the MESL were identified by liquid chromatography coupled to a diode array detector and mass spectrometer (LC-DAD-MS). The antioxidant activities of the extracts were analyzed by 2,2-diphenyl-1-(2,4,6-trinitrophenyl)hydrazyl radical (DPPH[rad]), 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) radical (ABTS[rad] + ), fluorescence recovery after photobleaching (FRAP), reducing power, β-carotene bleaching and malondialdehyde (MDA) assays in human erythrocytes. The antidiabetic properties of the extracts were demonstrated in vitro by their inhibition of the α-glucosidase enzyme and their anti-glycation activity via fructose and glyoxal. After showing no acute toxicity in vivo, MESL was able to lower postprandial glycemia after glucose overload in normoglycemic mice as well as the water and feed intake, liver weight, glycemia and serum levels of glycated hemoglobin, aspartate transaminase (AST) and alanine transaminase (ALT) in diabetic mice. Overall, S. terebinthifolius extracts showed microbiological safety along with antioxidant and antidiabetic activities, likely mediated by its chemical constituents, such as gallic acid, gallotannins and glycosylated flavonolsThis work was supported by grants from Foundation to Support to Fundação de Apoio ao Desenvolvimento do Ensino, Ciência e Tecnologia do Estado de Mato Grosso do Sul (FUNDECT), Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), and Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq).info:eu-repo/semantics/publishedVersio

Antiobesity Effects of Hydroethanolic Extract of Jacaranda decurrens
Obesity is a worldwide epidemic that reduces life expectancy; therefore, the search for new alternative and effective treatments is ongoing. The aim of the present investigation was to identify the chemical compounds in the hydroethanolic extract of leaves of Jacaranda decurrens subsp. symmetrifoliolata and to evaluate their toxicity and antiobesity effects. High-performance liquid chromatography was used to identify the chemical constituents, and acute toxicity was evaluated in rats treated with doses of 2 and 5 g·kg−1 body mass. The antiobesity effect was determined in rats with hypercaloric diet-induced obesity. Our results revealed the presence of compounds, such as jacaric, ursolic, and oleic acids, as well as luteolin, quercetin, and kaempferol, in the extract. The acute toxicity tests revealed that rats treated with elevated doses of the extract showed no signs of toxicity. The extract induced reduction in total body mass and the white adipose tissue depots. The obese rats treated with the extract showed an increased fluid intake and feces excretion while their serum total cholesterol and triglyceride levels decreased compared to those in the controls, without any hematological changes. Taken together, the results showed that the constituents of J. decurrens extracts included phenolic compounds and exhibited antiobesity effects with no toxicity
Influence of grape seed oil on sun protection factor in sunscreen formulations: a study using Central Composite Design approach
This study aimed to evaluate the influence of the grape seed oil (GSO) on the sun protection factor (SPF) of sunscreen emulsified formulations containing butyl methoxydibenzoylmethane (avobenzone (AVO)) and octyl methoxycinnamate (OMC) developed by phase inversion temperature (PIT) employing a Central Composite Design. Formulations were prepared by PIT emulsification process. Seventeen emulsions containing different amounts of GSO, AVO and OMC were obtained according to experimental design. In vitro SPF was determined using a spectrophotometric method. As expected, formulations with the highest concentrations of UV filters, AVO and OMC, resulted in the highest SPF values, while the lowest SPF values were obtained by formulations containing concentrations of these filters below the central point. In the tested concentrations, the variable OMC and its combination with GSO showed to influence the SPF linearly as a function of their concentrations in formulations. The combination of GSO with OMC contributed to increase in vitro SPF. The use of natural compounds with antioxidant activity, such as GSO, is a viable strategy to increase the effectiveness of sunscreens to protect the human skin against UV-induced damage

Introdução: A partir do movimento da Reforma Psiquiátrica e com a aprovação da Lei Federal 10.216/2001, instituiu-se no Brasil uma política de saúde mental baseada no respeito aos direitos humanos e no tratamento em liberdade. Pesquisadores e usuários da saúde mental, através da experiência de países europeus, buscam incorporar novas estratégias de cuidado. A estratégia Gestão Autônoma da Medicação, orientada pelos princípios do recovery, se propõe a deslocar a centralidade do saber médico, proporcionando espaço de discussão com usuários, valorização de vivências, sentimentos e necessidades de cada indivíduo, por meio da corresponsabilização. Método: Trata-se de relato de experiência a respeito de um projeto de implantação de um grupo GAM como uma estratégia de melhoria de cuidado realizado em um Centro de Referência em Saúde Mental em Belo Horizonte. O projeto foi delineado e desenvolvido no âmbito da Residência Integrada de Saúde Mental do Hospital Odilon Behrens e Rede de Atenção Psicossocial de Belo Horizonte, realizada há quase uma década no município. Resultados: Desenvolveu-se um grupo GAM ao longo de três meses, com participação de, em média, cinco usuários por encontros semanais, com duração de uma hora cada. Conclusão: A estratégia GAM mostrou-se como ferramenta capaz de convocar trabalhadores e usuários para ocuparem um espaço coletivo de produção de cuidado, embora algumas dificuldades tenham surgido, como a pouca adesão. Todavia, o processo de implementação da estratégia demonstrou plausível sua aplicabilidade, mesmo em um dispositivo de urgência.Introduction: From the Psychiatric Reform movement and with the approval of Federal Law 10,216/2001, a mental health policy based on respect for human rights and treatment in freedom was instituted in Brazil. Mental health researchers and users, through the experience of European countries, seek to incorporate new care strategies.
