Flavanol monomer-induced changes to the human faecal microflora [PDF]

, 2008
We have investigated the bacterial-dependent metabolism of ( − )-epicatechin and (+)-catechin using a pH-controlled, stirred, batch-culture fermentation system reflective of the distal region of the human large intestine.

A prebiotic intervention study in children with autism spectrum disorders (ASDs)

Microbiome, 2018
Different dietary approaches, such as gluten and casein free diets, or the use of probiotics and prebiotics have been suggested in autistic spectrum disorders in order to reduce gastrointestinal (GI) disturbances.

Nitrate as a potential prebiotic for the oral microbiome

Scientific Reports, 2020
The salivary glands actively concentrate plasma nitrate, leading to high salivary nitrate concentrations (5–8 mM) after a nitrate-rich vegetable meal.

Intestinal histomorphology, autochthonous microbiota and growth performance of the oscar (Astronotus ocellatus Agassiz, 1831) following dietary administration of xylooligosaccharide [PDF]

, 2016
The present study investigates the changes in intestinal histomorphology, autochthonous microbiota and growth performance of the oscar, Astronotus ocellatus, following dietary administration of different levels of xylooligosaccharide (XOS).

DNA Renaturation at the Water-Phenol Interface [PDF]

, 2003
We study DNA adsorption and renaturation in a water-phenol two-phase system, with or without shaking. In very dilute solutions, single-stranded DNA is adsorbed at the interface in a salt-dependent manner.

Chirality Makes or Breaks Chemically Driven Self‐Assembly

Angewandte Chemie, EarlyView.
Chirality‐controlled reaction cycles: Reaction cycles are constructed to respond to the chirality (handedness) of an acylating agent. Left‐ and right‐handed aminoacyl phosphate esters modulate the structure, lifetime, and transformation of transient (thio)ester intermediates, enabling control over distinct chemical pathways using molecules that are ...

Prebiotic Organic Globules [PDF]

, 2010
Analogs of organic globules observed in carbonaceous chondrite meteorites and in interplanetary dust particles and of rod to spherical structures observed in terrestrial archean microstructures have been synthesized in our experiments conducted with ...

Chiral Polymerization in Open Systems From Chiral-Selective Reaction Rates

, 2012
We investigate the possibility that prebiotic homochirality can be achieved exclusively through chiral-selective reaction rate parameters without any other explicit mechanism for chiral bias.

Mixed Spices at Culinary Doses Have Prebiotic Effects in Healthy Adults: A Pilot Study. [PDF]

, 2019
Spices were used as food preservatives prior to the advent of refrigeration, suggesting the possibility of effects on microbiota. Previous studies have shown prebiotic activities in animals and in vitro, but there has not been a demonstration of ...
