High pressure processing applied for enhancing the antioxidant content of minimally processed peaches por Denoya, Gabriela Inés, Polenta, Gustavo Alberto, Apóstolo, Nancy Mariel, Budde, Claudio Olaf, Cristianini, M., Vaudagna, Sergio Ramon

“…Therefore, minimally processed peaches were subjected to HPP-treatment with different pressure levels (100, 300, 500 MPa) and holding times (1,5 min). Results showed that 300 and 500 MPa induced a significant increase in the antioxidant content, which can be partially linked to the increase in the extractability of these compounds brought about by the changes in the microstructure. …”

Agricultural intensification impairs behavioral abilities and the expression of genes associated with social responsiveness in honeybees por Macri, Ivana Noelia, Moja, Pablo Joaquín, Latorre Estivalis, Jose M., Cristos, Diego Sebastian, Zavala, Jorge Alberto, Farina, Walter Marcelo

“…Here, behavioral, molecular, and toxicological approaches were performed in beehives located in an agricultural setting of the Argentine pampas to compare their global state at different times of crop management. Our results show that foraging bees were impaired in their sensory and cognitive abilities and the brain’s expression of several genes related to metabolic, immune, and neuronal processes associated with social behavior after crop flowering and pesticide application. …”
