Objectives: To estimate the prevalence of allergic rhinitis (AR), atopic dermatitis (AD), and wheezing, and to describe their patterns of co-occurrence according to different characteristics in adolescence and early adulthood.
Methods: Cross-sectional analyses from the 15-year and 22-year follow-ups of the 1993 Pelotas (Brazil) Birth Cohort. The outcomes were assessed based on self-reported data, and the patterns of co-occurrence were determined using cluster analysis.

Herein, we assessed the potential toxicogenic and/or oxidant effects of hydroxyurea associated with ascorbic acid by examinations in and human cancer cells and systemically on mice tissues. Growing roots and HCT-116 colorectal tumor cells were examined after HU and HU plus ascorbic acid exposure.

- - The velvetbean caterpillar significantly affects soybean crops in Brazil, and biopesticides like Bt (Bacillus thuringiensis) utilize Crystal toxins (Cry) to kill these pests by targeting their midgut receptors, such as aminopeptidase N (APN).
- - This study aims to identify and characterize APNs in the caterpillar’s midgut to understand how Cry1Ac interacts with its receptors, which is vital for managing pest resistance against the biopesticide.
- - Research methods included immunohistochemistry, aminopeptidase activity assays, and mass spectrometry, leading to the discovery of seven APNs potentially involved in Cry toxin binding, as well as variations in expression levels
Xenarthran mammals of the suborder Folivora are arboreal species that feed mainly on leaves and Cecropia spp, an abundant plant in the Brazilian Amazon region, is favoured. The stomach of sloths represents 20-30% of their body weight and is adapted to gastric fermentation of plant material. These anatomical and physiological adaptations can be altered by many factors when confined to captivity, which favours fatal gastric conditions.
