Gut Microbiota-derived Bile Acids Promote Gamma-secretase Activity Through Interactions with Nicastrin Subunits [PDF]
arXiv, 2023 Alzheimer's disease (AD) has emerged as a progressively pervasive neurodegenerative disorder worldwide. Bile acids, synthesized in the liver and modified by the gut microbiota, play pivotal roles in diverse physiological processes, and their dysregulation in individuals with AD has been well-documented.

The effects of carboxylic acids on the aqueous dispersion and electrophoretic deposition of ZrO2 [PDF]
Journal of the European Ceramic Society, Volume 32, Issue 1, 2012,
Pages 235-244, 2013 The agglomeration, electrokinetic properties and electrophoretic deposition behaviour of aqueous suspensions of ZrO2 with carboxylic acid additives were studied in comparison with conventional pH adjustment. It was found that citric acid imparted negative zeta-potential values and electrosteric stabilisation to particles in suspensions at all pH levels.

Learning the Hydrophilic, Hydrophobic and Aromatic Character of Amino Acids from their Interfacial Thermal Conductance in Water [PDF]
, 2021 In this study, the thermal relaxation of the 20 naturally occurring amino-acids in water is investigated using transient non-equilibrium molecular-dynamics simulations. By modeling the thermal relaxation process, the relaxation times of the amino-acids in water occurs over a timescale covering 2-5 ps.

Inferring ozone production in an urban atmosphere using measurements of peroxynitric acid [PDF]
Atmospheric Chemistry and Physics, 2009 Abstract. Observations of peroxynitric acid (HO2NO2) obtained simultaneously with those of NO and NO2 provide a sensitive measure of the ozone photochemical production rate. We illustrate this technique for constraining the ozone production rate with observations obtained from the NCAR C-130 aircraft platform during the Megacity Initiative: Local and ...

Kinetics of Bacterial Inactivation by Peroxynitric Acid in the Presence of Organic Contaminants
Applied and Environmental Microbiology, 2021 A good disinfectant for the human body should have various properties, such as strong bactericidal activity, harmlessness to living tissues, and resistance against biological fluids (or other organic contaminants). Peroxynitric acid (PNA) showed a bactericidal effect that was several tens up to several hundred times higher per unit of molarity than ...

Nature's Starships. I. Observed Abundances and Relative Frequencies of Amino Acids in Meteorites [PDF]
, 2014 The class of meteorites called carbonaceous chondrites are examples of material from the solar system which have been relatively unchanged from the time of their initial formation. These meteorites have been classified according to the temperatures and physical conditions of their parent planetesimals.

Meteoritic Abundances of Fatty Acids and Potential Reaction Pathways in Planetesimals [PDF]
Icarus, 2019, 319, 685-700, 2018 The origin of fatty acids on the prebiotic Earth is important as they likely formed the encapsulating membranes of the first protocells. Carbon-rich meteorites (i.e., carbonaceous chondrites) such as Murchison and Tagish Lake are well known to contain these molecules, and their delivery to the early planet by intense early meteorite bombardments ...

Plasma–Liquid Interaction for Agriculture—A Focused Review
Plasma Processes and Polymers, Volume 22, Issue 1, January 2025.This article presents an overview of the applications of plasma activated water (PAW) in the field of agriculture, focusing on the chemistry of long‐lived reactive species and their roles in plant cell mechanisms. We describe different types of discharges for the production of PAW and its application to seeds and plants.
