The multidrug and toxin extrusion (MATE) transporter DTX51 antagonizes non‐cell‐autonomous HLS1–AMP1 signaling in a region‐specific manner

open access: yesFEBS Letters, EarlyView.
The Arabidopsis mutants hls1 hlh1 and amp1 lamp1 exhibit pleiotropic developmental phenotypes. Although the functions of the causative genes remain unclear, they act in the same genetic pathway and are thought to generate non‐cell‐autonomous signals.

Minería y vulnerabilidad de los territorios rurales en los Andes ecuatorianos: evidencias desde la provincia del Azuay

open access: yesCuadernos de Geografía: Revista Colombiana de Geografía, 2018
En los Andes ecuatorianos, la agricultura familiar se encuentra desde hace varias décadas en una situación de gran vulnerabilidad. A pesar de la reciente renovación del discurso político en Ecuador y del advenimiento de la era del “Buen Vivir”, el auge ...

From the diffusion coefficient to the diffusion tensor [PDF]

open access: yesNMR in Biomedicine, 2002
AbstractWith diffusion tensor MRI one has access to the organization in space of tissue microstructural components. This outstanding potential adds, however, another layer of complexity to the diffusion MRI data acquisition and analysis processes. Over the last few years many articles have been published dealing with those matters.

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

open access: yesFEBS Letters, EarlyView.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Short communication: Bifidobacterium abundance in the faecal microbiota is strongly associated with milk traits in dairy cattle

open access: yesAnimal
The performance of dairy cows is influenced by the microbial communities hosted within their digestive tract. While the rumen microbiota has long been associated with host phenotypes, the impact of the faecal microbiota remains elusive. In this study, we

A statistical approach to surface renewal: The virtual chamber concept

open access: yesAgrosystems, Geosciences & Environment, 2021
In the stable conditions prevailing at night, concentrations of emitted gases (e.g., radon [Rn], carbon dioxide [CO2], methane [CH4], ammonia [NH3], and nitrous oxide [N2O]) build up at the surface, with intermittent interruptions due to the passage of ...

Generating Diffusion MRI scalar maps from T1 weighted images using generative adversarial networks

open access: yes, 2019
Diffusion magnetic resonance imaging (diffusion MRI) is a non-invasive microstructure assessment technique. Scalar measures, such as FA (fractional anisotropy) and MD (mean diffusivity), quantifying micro-structural tissue properties can be obtained ...
