Toxoplasmosis is a disease caused by an obligate intracellular protozoan, Toxoplasma gondii (T. gondii). The gastrointestinal tract is therefore a major route of T. gondii infection in most cases. For this reason the intestinal epithelium is a cellular model that provides to study the first line of defense against oral infections. The gap junctions, mediated by connexin 43 (Cx43), that have the role of mediating the interactions between adjacent cells.

Visando identificar os resultados financeiros da cultura da erva-mate (Ilexparaguariensis) consorciada com a apicultura, em propriedade de agricultura familiar, a pesquisa apresenta possibilidades de geração de renda e diversificação de produção no âmbito das pequenas glebas rurais. A diversificação da renda é uma estratégia incentivada em propriedades praticantes da agricultura familiar pois possibilita otimizar os recursos aplicados, ter diferentes fontes de renda e propicia melhor aproveitamento da área territorial disponível.

This study explores the relationship of school dropout with poverty, having as interface the family with students in the modality of Youth and Adult Education (YAE). To this end, the context and influence of the family as a generational link of poverty is a premise for the issue of school dropout, age/grade distortion, and absenteeism. Indeed, many young people and adults who are unable to complete their studies build families and throughout their lives the generational poverty system is likely to be permeated by lack of educational qualification.

The present study has aimed to assess the soil mesofauna groups' density and diversity, as well as their relationship with chemical attributes of a Yellow Oxisol being managed for fourteen years with biochar (BC) increasing doses. This study was undertaken at an Experimental Station of the National Institute for Amazonian Research, in Manaus-AM. The experimental design was in randomized blocks, with four doses of BCand four replications (blocks), totaling 16 experimental units.

The water needs of agricultural crops are one of the most important factors affecting the selection of crops suitable for agriculture, which affect crop productivity and thus the availability of human food.

Candida albicans is one of the most prevalent pathogenic fungi worldwide and in recent decades has shown resistance to azoles and echinocandins. Therefore, the search for therapeutic alternatives is necessary in order to combat infections caused by this fungus. This study evaluated the chemical composition and the effects of Cnidoscolus urens methanolic extract, derived from the plant latex, on virulence attributes of C. albicans. The ability of the methanolic extract of C.

The objective of the present study is to analyze the influence of the COVID-19 pandemic on the menstrual cycle, from the evaluation of biological and psychosocial factors of women who contracted the disease compared to those who did not. A cross-sectional study was carried out with data collected through an online questionnaire that was self-completed by the participants. A total of 113 university students were included in the study, all of them of childbearing age and during the pandemic period.

Plant tissue culture allows the clonal propagation of Coffea canephora on a large scale through somatic embryogenesis. The aim of this study was to optimize the conditions for the induction of somatic embryogenesisin leaves of the Robusta variety. The physiological stage of the leaves – drain or source; the use of the surrounding area ofprimary or secondary veins; and the position of the explants – abaxial or adaxial surface in contact with the culture medium were evaluated.
