MD simulations and multivariate studies for modeling the antileishmanial activity of peptides
(Wiley-Blackwell, 2017-10-01)
Leishmaniasis, a protozoan-caused disease, requires alternative treatments with minimized side-effects and less prone to resistance development. Antimicrobial peptides represent a possible choice to be developed. We report ...
Biological evolution: ECO-EVO-DEVO in initial teachers and researchers education
(Univ Francisco Jose Caldas, Fac Science & Education, 2017-07-01)
Epistemology is an area that allows reflections about nature and construction of knowledge. In what is referred to Biological Sciences, the concept of evolution is understood as unifier axis of this science and therefore ...
Use of personal protective equipment in a radiology room at a veterinary teaching hospital
(Wiley-Blackwell, 2018-03-01)
The use of personal protective equipment by veterinary workers during radiographic imaging is inconsistent. While the self-reported use of leaded aprons and thyroid shields approaches 100% in some studies, the use of leaded ...
