Irritability in preschool children with attention‐deficit/hyperactivity disorder: Analysis of family environmental factors

JCPP Advances, EarlyView.
Abstract Background Irritability affects one‐third of children and adolescents with attention‐deficit/hyperactivity disorder (ADHD) and is associated with negative outcomes. The family environment plays a prominent role in the child's development, and therefore on the risk for irritability, especially during the preschool period.

Oxypropylation of Brazilian Pine-Fruit Shell Evaluated by Principal Component Analysis

Journal of Renewable Materials, 2018
Pine-fruit shell (PFS) is a lignocellulosic residue derived from the fruit of Araucaria angustifolia, a coniferous tree native of South America, part of a whole vegetation of the Atlantic Forest, found in the South and Southwest of Brazil. In this work PFS will be characterized and used in the production of PFS-based polyols through oxypropylation ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Estimating the critical angle of top near‐surface layers on the Moon

Near Surface Geophysics, EarlyView.
Abstract Near‐surface characterization of the lunar subsurface is essential for future exploration and infrastructure development, particularly for the construction of underground habitats that provide protection against radiation and micrometeorites. However, conventional seismic approaches for estimating subsurface properties typically rely on prior ...
