Appropriate margin for planning target volume for breast radiotherapy during deep inspiration breath-hold by variance component analysis

open access: yesRadiation Oncology, 2021
Background This study aimed to quantify errors by using a cine electronic portal imaging device (cine EPID) during deep inspiration breath-hold (DIBH) for left-sided breast cancer and to estimate the planning target volume (PTV) by variance component ...

Functional characterization of NRT1/PTR FAMILY transporters: looking for a needle in a haystack

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1124-1144, February 2026.
Summary NRT1/PTR FAMILY (NPF) transporters play crucial roles in plant physiology and development due to their involvement in nitrogen nutrition and their ability to transport multiple signaling molecules and metabolites. Whereas most eukaryotic and prokaryotic NPF orthologs are peptide transporters, most flowering plant NPF transport other substrates ...

ENFERMEDAD PULMONAR INTERSTICIAL DIFUSA (EPID)

open access: yesRevista 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 ...

SWEET1‐mediated glucose transport is crucial for energy availability in Arabidopsis

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1816-1830, February 2026.
Summary The stress‐responsive hormone abscisic acid (ABA) is known for its inhibitory effects on various physiological processes, including seed germination, often resulting in energy deprivation. Interestingly, ABA‐induced germination inhibition can be alleviated by exogenous glucose (Glc), mimicking a functional interplay between ABA and sugar ...
