Gut Microbiota Differences in Down Syndrome Are Most Pronounced in Childhood and Diminish With Age. [PDF]

Int J Microbiol
Introduction Down syndrome (DS) is linked to increased risks of metabolic, gastrointestinal, and neurodegenerative disorders. Early alterations in the gut microbiota have potential long‐term health impacts. This report appears to be the first study to stratify DS participants by age to explore early‐life microbiota changes.

Plant species-specific rhizobiome assembly in the hyper-arid Atacama Desert [PDF]

Frontiers in Microbiology
The hyper-arid core of the Atacama Desert represents one of the oldest and driest regions of the world and is characterized by high aridity (precipitation <2 mm y−1), hypersaline soil conditions, extremes in temperature (−5 °C to 50 °C), intense UV ...

Mathematical Model for Scaling up Bioprocesses Using Experiment Design Combined with Buckingham Pi Theorem

Applied Sciences, 2021
Scaling up bioprocesses from the experimental to the pilot or industrial scale involves heuristics and scale relationships that are far from the specific phenomena and are usually not connected to the experimental data. In complex systems, the scaling-up

Methane Hydrate Behavior for Water–Oil Systems Containing CTAB and Synperonic PE/F127 Surfactants

Energies, 2022
Methane hydrates were studied in systems containing aqueous dissolved surfactants in oil emulsions with a volume ratio of 40/60. Two commercial surfactants, named synperonic PE/F127 and cetyltrimethylammonium bromide, were evaluated at 0, 350, 700 and ...
