Prebiotic effects: metabolic and health benefits [PDF]
The different compartments of the gastrointestinal tract are inhabited by populations of micro-organisms. By far the most important predominant populations are in the colon where a true symbiosis with the host exists that is a key for well-being and ...

Prebiotic Homochirality as a Critical Phenomenon [PDF]
The development of prebiotic homochirality on early-Earth or another planetary platform may be viewed as a critical phenomenon. It is shown, in the context of spatio-temporal polymerization reaction networks, that environmental effects -- be them temperature surges or other external disruptions -- may destroy any net chirality previously produced.

Nitrogen Oxide Concentrations in Natural Waters on Early Earth [PDF]
A key challenge in origins-of-life studies is estimating the abundances of species relevant to the chemical pathways proposed to have contributed to the emergence of life on early Earth. Dissolved nitrogen oxide anions (NO$_{X}^{-}$), in particular nitrate (NO$_{3}^{-}$) and nitrite (NO$_{2}^{-}$), have been invoked in diverse origins-of-life chemistry,

The first peptides: the evolutionary transition between prebiotic amino acids and early proteins [PDF]
The issues we attempt to tackle here are what the first peptides did look like when they emerged on the primitive earth, and what simple catalytic activities they fulfilled. We conjecture that the early functional peptides were short (3 to 8 amino acids long), were made of those amino acids, Gly, Ala, Val and Asp, that are abundantly produced in many ...

Prebiotic, Probiotic, and Synbiotic Supplementation in Chronic Kidney Disease: A Systematic Review and Meta-analysis [PDF]
Gut dysbiosis has been implicated in the pathogenesis of chronic kidney disease (CKD). Restoring gut microbiota with prebiotic, probiotic, and synbiotic supplementation has emerged as a potential therapeutic intervention but has not been systematically ...

Carob Syrup: Prebiotic Potential of a Neglected Functional Beverage of Mediterranean Countries [PDF]
Carob syrup, a traditional Mediterranean functional beverage obtained from Ceratonia siliqua (L.) pods, has been historically valued for its nutritional properties but is currently underutilized.

A thermodynamic basis for prebiotic amino acid synthesis and the nature of the first genetic code [PDF]
Of the twenty amino acids used in proteins, ten were formed in Miller's atmospheric discharge experiments. The two other major proposed sources of prebiotic amino acid synthesis include formation in hydrothermal vents and delivery to Earth via meteorites.

Changes of digestible starch composition and improvements of prebiotic properties in modified taro starch by heat treatment [PDF]
This study investigated the composition of digestible starch and prebiotic properties of taro starch due to different heating treatments. The taro starch has been treated by annealing (24 hrs, 50 °C), heat moisture treatment (moisture 25%, 3 hrs, 110 ...
