Polyphenols are compounds of secondary metabolism in plants and their action is recognized in the control against free radicals and reactive oxygen species. Th e study aimed to indicate polyphenols and their intake in fruits and vegetables as a protective action for human health due to stress against Covid-19. Given the rapid spread of the emerging pandemic Covid-19, it continues to be of great concern due to the mortality that occurs globally and there is no doubt about the level of stress in the population. Attempts to fl atten the epidemiological curve are diverse in that Covid-19 could not only aff ect psycho-mentally, but some non-communicable diseases may perhaps debut. Considering the serious situation, from the axiological point of view, a question arises: can the daily consumption of fruits and vegetables in the diet patterns generate, from the metabolic point of view, any poten...

The purpose of the study was to describe the analytical bioevaluation of the predictive model of science in aquatic ecotoxicology. From the Sciencedirect website, 18 scientific reviews, 72 scientific articles, six encyclopedias and 32 book chapters corresponding to 11 scientific journals were analyzed. Two descriptors were proposed: 1st) of the field conditions which referred to the natural development of organisms and, 2nd) of the laboratory conditions where three types of tests were considered: A) potential of toxicity, B) of growth and, C) transformation. Although, the advantage of field conditions is the disadvantage in laboratory conditions, it is essential that bio-assessments are combined for ecosystem services to be sustainable in society. From various bioevaluations of field and laboratory conditions, data that have statistical significance and its argumentation constitute new p...

Yes __ No __”. “Do you wear a double mask on public roads or in public spaces? Yes __ No __”. “Do you frequently eat food in public places with your family? Yes __ No __”. Likewise, the relationship between wearing and removing the mask by ...

Any global crisis will be more damaging in regions such as Latin America and the main solutions should not come from a pattern of technoscience that exists in developed countries. Given the health situation that occurs on the planet, prevention models are inherited and even hospital and community treatment practices that in various settings are incomprehensible and inappropriate. Th e objective of this note was to communicate the perception of decolonizing epistemological thinking in Latin America as the closest social evidence since the COVID-19 pandemic. Th e conceptual operability of resources, interpretation and productive modes of knowledge always prevent non-adjustable or delayed programs from being interpolated and that are probably contradictory to the conditions and refl ective forms in each territory.
