Orally Administered Functional Polyphenol‐Nanozyme‐Armored Probiotics for Enhanced Amelioration of Intestinal Inflammation and Microbiota Dysbiosis

Advanced Science, EarlyView.
This study presents a novel polyphenol‐nanozyme‐armored probiotic system (ECA@EcN) for enhanced treatment of inflammatory bowel disease (IBD). By integrating chitosan‐modified epigallocatechin gallate (EGCG‐CS) with gold nanozymes, the system effectively scavenges ROS, improves probiotic viability, and restores gut microbiota balance.

Inulin‐type fructans and short‐chain fructooligosaccharides—their role within the food industry as fat and sugar replacers and texture modifiers—what needs to be considered!

Food Science &Nutrition, Volume 11, Issue 1, Page 17-38, January 2023., 2023
Inulin‐type fructans and short‐chain fructooligosaccharides are becoming and increasingly common ingredient used in the food industry as fat and sugar replacers and texture modifiers. Yet careful consideration must be given to the type and quantity of fructans used in replacement of fat and sugar in order product integrity while maintaining product ...

Setting the geological scene for the origin of life and continuing open questions about its emergence

Frontiers in Astronomy and Space Sciences, 2023
The origin of life is one of the most fundamental questions of humanity. It has been and is still being addressed by a wide range of researchers from different fields, with different approaches and ideas as to how it came about.

Extraterrestrial Photochemistry: Principles and Applications [PDF]

arXiv, 2021
Energetic processing of interstellar ice mantles and planetary atmospheres via photochemistry is a critical mechanism in the extraterrestrial synthesis of prebiotic molecules. Photochemistry is defined as chemical processes initiated by photon-induced electronic excitation, not involving ionization.

Titan Mare Explorer (TiME): first in situ exploration of an extraterrestrial sea [PDF]

, 2010
The lakes and seas of Titan are a sink of products of photolysis in the atmosphere, and a crucial component in Titan's active methane cycle.

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.

Resilient Membranized Coacervates Formed through Spontaneous Wrapping of Heat‐Destabilized Lipid Bilayers around Coacervate Droplets

Advanced Science, EarlyView.
We present a universal way to wrap liposomes around coacervate droplets. Membrane‐enclosed coacervates form when heat‐destabilized liposomes are mixed with coacervates. Membranized coacervates (MCs) can survive pH and ionic strength fluctuations, osmotic stress, and low temperatures.

Characterization of ultrasonically extracted flaxseed polysaccharide gum and assessing its lipid‐lowering potential in a rat model

Food Science &Nutrition, Volume 11, Issue 1, Page 137-147, January 2023., 2023
On the basis of current research it was suggested that FPG have anti‐hyperlipidemic potential. Still, the mechanism of actions of FPG as anti‐hyperlipidemic and other therapeutic potential have yet to be explored. Abstract Flaxseed polysaccharide gum (FPG) was extracted through the ultrasound‐assisted process using water as a solvent with a yield ...

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 ...
