Root hair plasticity in cereals under abiotic stress
New Phytologist, Volume 251, Issue 4, Page 1684-1693, August 2026.An integrative perspective on how to study the regulation of root hair plasticity to increase the resilience of cereals to abiotic stress. Summary Abiotic stress is a constant threat to crop growth and yield in the context of climate change. Root systems that can best adapt their architecture to environmental challenges contribute to enhanced ...

EPIDs and QA of advanced treatments
Journal of Physics: Conference Series, 2019 Abstract In this paper I will summarize the various possibilities of EPIDs for their use as tools for QA of advanced treatments. After elucidating the choice of EPIDs for this purpose, I will review the use of EPIDs for pre-treatment and in vivo (transit) dosimetry applications.

ENFERMEDAD PULMONAR INTERSTICIAL DIFUSA (EPID)
Revista Cuarzo, 2016 Si bien es cierto que la radiografía simple del tórax permite sospechar la presencia de enfermedad pulmonar instersticial, la tomografía axial computarizada (TACAR) es más sensible y específica en la valoración de pacientes con esta enfermedad. En este artículo se trata sobre los patrones básicos que permiten identificar los diversos grupos de EPID ...
