In Vitro Evaluation of Prebiotic Potential of Red Ginger (Zingiber officinale var. rubrum) Rhizome Ethanol Extract on Lactobacillus acidophilus and Escherichia coli

Borneo Journal of Pharmacy
Prebiotics, including carbohydrates and phenols, promote beneficial gut bacteria (probiotics). Red ginger (Zingiber officinale var. rubrum) rhizomes, rich in these compounds, have been traditionally used in medicine but their prebiotic potential remains

Atmospheric Constraints on the Surface UV Environment of Mars at 3.9 Ga Relevant to Prebiotic Chemistry [PDF]

, 2017
Recent findings suggest Mars may have been a clement environment for the emergence of life, and may even have compared favorably to Earth in this regard. These findings have revived interest in the hypothesis that prebiotically important molecules or even nascent life may have formed on Mars and been transferred to Earth.

The origin of life: chemical evolution of a metabolic system in a mineral honeycomb? [PDF]

, 2009
For the RNA-world hypothesis to be ecologically feasible, selection mechanisms acting on replicator communities need to be invoked and the corresponding scenarios of molecular evolution specified.

Gut Microbiota Colonization in Early Life Influences Susceptibility to Adulthood Hepatic Lipid Accumulation in High‐Fat‐Diet‐Fed Mice

Advanced Science, EarlyView.
This study indicates that perinatal antibiotic exposure elevates susceptibility to high‐fat‐diet‐induced hepatic lipid accumulation via disrupting early‐life gut microbiota colonization. The decreased Lactobacillus colonization inhibits primary‐to‐secondary bile acid conversion, lowering secondary bile acids, enhancing adulthood intestinal lipid ...

Environmental History is Transferred via Minerals Altering Formose Reaction Pathways

Angewandte Chemie, EarlyView.
We study the influence of minerals on the formose reaction. We found that different minerals have distinct impact on the network outcome effects, that change over sequential batch reactions, demonstrating a history effect. Finally, we show that when minerals are first incubated with the aqueous catalysts, they subsequently allow for formation of ...

Enhancing Broiler Growth Performance and Gut Health: A Comparative Study on the Impact of Probiotics, Prebiotics, and Pomegranate (Punica granatum L.) Peel Powder [PDF]

Brazilian Journal of Poultry Science
A total of 200 one-day-old Ross 308 male broilers were randomly assigned to 4 treatments and 5 replicates in a completely randomized design to assess growth performance, serum biochemicals, and intestinal characteristics for 42 days. Treatments comprised

Cosmic dust fertilization of glacial prebiotic chemistry on early Earth [PDF]

Earth. Nat Astron (2024)
Earth's surface is deficient in available forms of many elements considered limiting for prebiotic chemistry. In contrast, many extraterrestrial rocky objects are rich in these same elements. Limiting prebiotic ingredients may, therefore, have been delivered by exogenous material; however, the mechanisms by which exogeneous material may be reliably and

Dynamics of growth and form in prebiotic vesicles [PDF]

Phys. Rev. Lett. 123, 038102 (2019), 2019
The growth, form, and division of prebiotic vesicles, membraneous bags of fluid of varying components and shapes is hypothesized to have served as the substrate for the origin of life. The dynamics of these out-of-equilibrium structures is controlled by physicochemical processes that include the intercalation of amphiphiles into the membrane, fluid ...

Lactobacillus johnsonii Generates Cyclo(pro‐trp) and Promotes Intestinal Ca2+ Absorption to Alleviate CKD–SHPT

Advanced Science, EarlyView.
The mechanism map of how L.johnsonii generates cyclo(pro‐trp) to alleviate CKD–SHPT by promoting the expression of CaSR and TRPV4 in IECs, enhancing Ca2+ absorption, and negatively feedback inhibiting iPTH secretion. Abstract Patients with chronic kidney disease (CKD) are at a high risk of developing secondary hyperparathyroidism (SHPT), which may ...
