Resumo Trata-se de ensaio, embasado na literatura sobre o tema, que tem como objetivo refletir acerca dos eventos relacionados ao processo de trabalho que comprometem a saúde mental de docentes de Instituições de Ensino Superior (IES) em tempos de covid-19. A falta de habilidade no manuseio de tecnologias da informação e comunicação no desenvolvimento das atribuições profissionais, a autocobrança e a pressão das IES para adaptação ao novo modelo de trabalho e a necessidade de gerenciar os afazeres laborais e domésticos constituem eventos que predispõem ao sofrimento psicoemocional em docentes do ensino superior.

Abstract This essay, based on the literature on the subject, aims to reflect on events related to the work process that compromise the mental health of Higher Education Institutions’ (HEI) professors in times of covid-19. The lack of skill in handling information and communication technology for the undertaking of professional assignments, the act of demanding too much from oneself and the pressure from the HEI to adapt to the new work model, as well as the need to manage work and household chores are events that predispose to psycho-emotional suffering in higher education teachers.

Ultrathin sections of tissue cysts isolated from the brain of Toxoplasma gondii infected mice were submitted to two different methodologies derived from the periodic acid - Schiff's reagent (PAS) technique. The use of osmium tetroxide vapor as a developing agent of the aldehyde oxidation to reveal polysaccharides with periodic acid resulted in positive reaction in amylopectin granules in bradyzoites, as well as in the wall and matrix of the cysts, with excellent increment of the ultrastructural morphology. This technique can be used for study of T. gondii-host cell intracellular cycle, the differentiation tachyzoite-bradyzoite, and also for the formation of cysts into the host cells.
