O uso de plantas pode ser considerado uma das formas mais antigas de práticas terapêuticas. Com base nessa afirmação, o presente artigo buscou descrever os principais fatos históricos relativos à utilização de plantas medicinais desde a pré-história até a atualidade. O objetivo do trabalho foi a realização de um levantamento bibliográfico sobre o histórico de uso de plantas medicinais e a sua relevância frente a implementação de políticas públicas de saúde. A pesquisa foi realizada de setembro a outubro de 2020, sendo analisados artigos e dissertações presentes em bases de dados específicas (Schoolar Google, Science Direct e Pubmed). Ao término do estudo pode-se perceber a fundamental importância dos saberes populares presentes em diferentes culturas, como fator essencial a construção e implementação políticas sólidas de saúde, de âmbito nacional, como o Sistema Único de Saúde (SUS) e a Política Nacional de Plantas Medicinais e Fitoterápicos (PNPMF).

Due to their mass production and intense consumption in human medicine, veterinary, and aquaculture, antibiotics have been widely detected in different ecosystems, leading to a growing worldwide concern. These and their byproducts are being continuously discarded in natural ecosystems via excretion of human and animal urine and feces, also domestic and hospital effluents. Residues of these drugs can persist in natural environments through bioaccumulation due to their difficult biodegradation. Also, they have a gradual deposition in sediments, aquatic surfaces, and groundwater. Studies have shown the presence of these drugs in aquatic environments, which can trigger severe changes in the composition and structure of the bacterial community, such as the ability to develop and propagate genes resistant to these pollutants. In this context, this review aims to address the effects of the antibiotics on microorganisms present in impacted aquatic environments.
Research Article IJBM (2020) 4:10 Phytochemical profile and cytotoxic activitys of Zanthoxylum tingoassuiba A. St. Hil extract The Caatinga phytogeographic domain represents 11 % of the Brazilian territory and presents a plant singularity that is not described anywhere else in the world. From this perspective, this study aimed to evaluate the phytochemical and cytotoxic profile of the aqueous extract of the plant species Zanthoxylum tingoassuiba A. ST. Hil, in addition to the evaluation of the photoprotective activity. The methodology used for these analyzes consisted of the collection and determination of secondary compounds of the species, by thin layer chromatography, in addition to the evaluation of the cytotoxic activity by different methods, as well as the evaluation of the photoprotective activity by spectrometry. As a result, it was noticed that the extract did not present erythrocyte hemolysis, as well as cytotoxicity by MTT in relation to the controls.
Amburana cearensis is a medicinal species popularly known as "cherry" or "aroma amburana" that has wide distribution in South America, being characteristic of Seasonal Forests. It also occurs in Semideciduous Seasonal Forest, restricted to rocky or limestone outcrops; in Submontane Deciduous SubmontanaSe-asonalForest; in Dense Ombrophilous Forest (Atlantic Forest) and even in caatinga/dry forest. Taking into account the growing interest in the search for agents that act in the face of oxidative stress, without causing toxic effects to biological systems, the present study aimed to investigate the phytochemical composition and evaluate the antioxidant and hemotoxic activities in vitro of the aqueous extract obtained from the shells of Amburana cearensis (EAAc). Hemaglutination wasevaluated for human erythrocytes collected from people with the presence of O+ blood. In the face of the tests, Amburana cearensis presented significant results for antioxidant activity without causing erythrocyte hemolysis, highlighting the importance of the species as a source of antioxidant agents, which are recognized for blocking the evolution and acting to combat symptoms triggered by diseases associated with oxidative stress.
Review Article AJAP (2020) 3:12 Metabolism: Pancreas and glycemic regulating hormones Understanding the physiology of the metabolic regulation of hormones responsible for glycemic control is of fundamental importance for a thorough understanding of Diabetes Mellitus. In this scenario, this chapter is intended to explain this regulation, as well as the main hormones that participate in this metabolic process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
