Prebiotics and Immune Responses
Journal of Pediatric Gastroenterology and Nutrition, 2004Feeding breast milk of healthy mothers is associated with a lower incidence of infectious and allergic diseases. Although this effect is of multifactorial origin, it is widely accepted that the entire intestinal flora of breastfed infants provides anti-infective properties and is an important stimulating factor for the postnatal development of the ...

Prebiotics for Probiotics [PDF]
, 2020 Owing to their perceived therapeutic effects, functional foods have been a matter of extensive research in recent years. Prebiotics, probiotics and synbiotics are the important members of this family exhibiting property that improves health, mental well-being and particularly reflected as an outcome of optimized gastrointestinal health status. The most

Origins of Life and Evolution of Biospheres, 2014
This short communication summarizes a global and continuous reflection on the origins of life. "Prebiotic Petroleum" assumes that "the class of most complex molecules of life that may have geochemical and abiotic origin is the class of fatty acids with long aliphatic chains" and proposes a physical process for the formation of liposomes.

Prebiotics and lipid metabolism
Current Opinion in Lipidology, 2002Prebiotics are defined as nondigestible food ingredients that beneficially affect the host by selectively stimulating the growth or the activity of one or a limited number of bacteria (bifidobacteria, lactobacilli) in the colon. Dietary fructans are nutritionally interesting oligosaccharides that strictly conform to the definition of prebiotics and (in

Most of our understanding of the human colonic microbiota is derived from studying the microbial contents of fecal samples, because it is impractical to access the human large intestine during normal digestion, and as an alternative, bacteria detected in feces are most representative of populations present in distal region of the intestine. The colonic

Analysis of Probiotics and Prebiotics
2013Probiotics are live microorganisms that confer health benefits on the host when they are administered in adequate numbers (Coman et al. 2012, da Cruz et al. 2007, FAO/WHO 2002, Saad et al. 2012). Probiotics are supplements or foods that contain viable microorganisms that cause alterations of the microflora of the host.

Prebiotic Synthesis on Minerals: Bridging the Prebiotic and RNA Worlds
The Biological Bulletin, 1999An array of experimental findings suggest that the simple molecules required for the origin of life may have been available on the primitive Earth. The well-known MillerUrey electric discharge experiment yields HCN, amino acids, and carboxylic acids (1). Carbonaceous meteorites contain over 70 amino acids, some heterocyclic compounds, including purines,

Prebiotic Activation Processes
Nature, 1973Questions regarding the combination of amino acids and ribonucleotides to polypeptides and polynucleotides are investigated. Each of the reactions considered occurs in the solid state in plausible prebiotic conditions. Together they provide the basis for a unified scheme of amino acid and nucleotide activation. Urea, imidazole and Mg(++) are essential

Tolerance of Probiotics and Prebiotics
Journal of Clinical Gastroenterology, 2004The clinical efficacy of probiotics and prebiotics has been proved in several clinical settings. The authors review their proved or potential side effects. Probiotics as living microorganisms may theoretically be responsible for 4 types of side effects in susceptible individuals: infections, deleterious metabolic activities, excessive immune ...

Astrobiology, 2001
Equilibrium adsorption isotherm data for the purine base adenine has been obtained on several prebiotically relevant minerals by frontal analysis using water as a mobile phase. Adenine is far displaced toward adsorption on pyrite (FeS2), quartz (SiO2), and pyrrhotite (FeS), but somewhat less for magnetite (Fe3O4) and forsterite (Mg2SiO4). The prebiotic
