Anatomical Responses of Two Species under Controlled Water Restriction.

Quillay ( Molina) and peumo ( [Molina] Looser) are two tree species endemic to Chile that grow in Mediterranean climate zones, characterized by a summer season with high temperatures, high solar radiation, and low soil water availability. A study was conducted with 2-year-old and plants and two substrate water conditions: well-watered and controlled water restriction. At the end of the study, anatomical leaf modifications were analyzed.

In vitro bioaccessibility and uptake of β-carotene from encapsulated carotenoids from mango by-products in a coupled gastrointestinal digestion/Caco-2 cell model.

β-carotene is a carotenoid with provitamin A activity and other health benefits, which needs to become bioavailable upon oral intake to exert its biological activity. A better understanding of its behaviour and stability in the gastrointestinal tract and means to increase its bioavailability are highly needed. Using an in vitro gastrointestinal digestion method coupled to an intestinal cell model, we explored the stability, gastrointestinal bioaccessibility and cellular uptake of β-carotene from microparticles containing carotenoid extracts derived from mango by-products.

Multiple mycotoxin exposure of infants and young children via breastfeeding and complementary/weaning foods consumption in Ecuadorian highlands.

The dietary exposure to mycotoxins in Ecuadorian children aged 0-23 months (320 rural and 603 urban) was evaluated based on the intake of breast milk and staple cereals used as complementary/weaning foods. A probabilistic distribution approach by first order Monte Carlo simulation was adopted to assess the locally occurring mycotoxins (aflatoxins M and B in breast milk, ochratoxin A and deoxynivalenol in wheat noodles and oat flakes, and HT-2 toxin in polished rice). Overall, exposure was modest but higher for rural children due to their monotonous diet.

A school-based intervention improved dietary intake outcomes and reduced waist circumference in adolescents: a cluster randomized controlled trial.

Background: In Ecuador, adolescents' food intake does not comply with guidelines for a healthy diet. Together with abdominal obesity adolescent's inadequate diets are risk factors for non-communicable diseases. We report the effectiveness of a school-based intervention on the dietary intake and waist circumference among Ecuadorian adolescents.
