Bacterial community structure in a sympagic habitat expanding with global warming: brackish ice brine at 85-90 degrees N
(NATURE PUBLISHING GROUP, 2019)Larger volumes of sea ice have been thawing in the Central Arctic Ocean (CAO) during the last decades than during the past 800,000 years. Brackish brine (fed by meltwater inside the ice) is an expanding sympagic habitat ... -
Bacterially produced metabolites protect C. elegans neurons from degeneration
(Public Library of Science, 2020-03)Caenorhabditis elegans and its cognate bacterial diet comprise a reliable, widespread model to study diet and microbiota effects on host physiology. Nonetheless, how diet influences the rate at which neurons die remains ... -
Baroreflex Modulation During Acute High-Altitude Exposure in Rats
(Frontiers Media, 2020)Baroreflex (BR) control is critically dependent of sympathetic and parasympathetic modulation. It has been documented that during acute hypobaric hypoxia there is a BR control impairment, however, the effect of a natural ... -
BarR, an Lrp-type transcription factor in sulfolobus acidocaldarius, regulates an aminotransferase gene in a β-alanine responsive manner.
(Facultad de Ciencias, 2014)In archaea, nothing is known about the β-alanine degradation pathway or its regulation. In this work, we identify and characterize BarR, a novel Lrp-like transcription factor and the first one that has a non-proteinogenic ... -

Bayesian sampling with BeAtlas, a grid of synthetic Be star spectra I. Recovering the fundamental parameters of α Eri and β CMi
(Oxford University Press, 2023-09)Classical B emission (Be) stars are fast rotating, near-main-sequence B-type stars. The rotation and the presence of circumstellar discs profoundly modify the observables of active Be stars. Our goal is to infer stellar ... -
Beef production from dairy bulls under two different production systems and its effect on the fatty acid profile and beef quality.
(CIENCIAS, 2014)Bulls in dairy production are usually slaughtered at an early age to avoid production problems and unnecessary costs. However, the animals could be a source of additional income and better quality meat. The objective of ... -
Bending energy of 2D materials: graphene, MoS2 and imogolite
(ROYAL SOC CHEMISTRY, 2018)The bending process of 2D materials, subject to an external force, is investigated, and applied to graphene, molybdenum disulphide (MoS2), and imogolite. For graphene we obtained 3.43 eV angstrom(2) per atom for the bending ... -
