The genus Sobralia (Orchidaceae) is a plant species present in Ecuador, which lacks little research on its biological activity. Therefore, this study was proposed with the objective of determining the antibacterial activity and toxicity of five species of this genus. The seven plant samples were collected in five provinces of the country, the plant...

Research in toxicology has been insufficient in Ecuador, despite the reported cases of food products, particularly those derived from fisheries, with levels of contaminants that widely exceed the limits allowed for human consumption. Therefore, there is an urgent need for information to prevent and solve the environmental issues causing this situat...

Political talk shows have been one of the most relevant tools in political communication since they burst onto American television at the end of the 20th century (Baum & Jamison, 2006). The rise of «infotainment» (Thussu, 2007) in those years caused an alliance between political information and entertainment that had traditionally been addressed se...

Chlorpyrifos is widely used in agricultural and building industries to control many insects including termites. However, its low aqueous solubility and tendency to decompose under sunlight results in decrease in its efficiency. In the present study, chlorpyrifos was encapsulated into nano-sized poly (styrene-co-maleic anhydrite) using a mini-emulsi...

[Objective] The objective was to determine which of the two hydra species (Hydra attenuata or Hydra viridis) was more sensitive to two pesticides, and then use the most sensitive species as part of the battery of test organisms of the Ecotoxicological Studies Laboratory (ECOTOX). [Methodology] For this purpose, dilutions of two of the most commonly...

Introduction: Cytostatic agents are toxic concentrates used for the treatment of neoplastic diseases and are included in the group of «high-risk drugs». The danger associated with its handling was known in 1970, since then the exposure has been limited thanks to the implementation of standards that guarantee the protection. The introduction of safe...
