Caloric restriction reveals a metabolomic and lipidomic signature in liver of male mice [PDF]
, 2014 Lipid composition, particularly membrane unsaturation, has been proposed as being a lifespan determinant, but it is currently unknown whether caloric restriction (CR), an accepted life-extending intervention, affects cellular lipid profiles.

Immunology, EarlyView.Antibiotic‐induced dysbiosis of the gut microbiota shifts host tryptophan metabolism and impairs the innate immune response during Pseudomonas aeruginosa pulmonary infection. (A) Eubiosis: During eubiosis, the intestinal microbiota metabolises tryptophan into indole metabolites, which keeps tryptophan levels within normal serum concentrations. However,

Rapid Communications in Mass Spectrometry, Volume 39, Issue 13, 15 July 2025.ABSTRACT Rationale Several phytosterols (PSs), well known for their role in plant physiology and their health benefits, represent a subset of the family of 4‐desmethyl‐sterols. They exhibit remarkable structural variability due to differences in the number and position of C=C bonds in their tetracyclic backbone and side chain composition. When analysed

Applied Organometallic Chemistry, Volume 39, Issue 7, July 2025.Mn (II) complex with 4‐iodo‐pyridine‐2‐carboxylic acid and 5,5′‐dimethyl‐2,2′‐bipyridine has shown significant potential for nonlinear optical (NLO) applications, as evidenced by both static and frequency‐dependent NLO analyses. This is attributed to the interaction between Mn (II) ion and the coordinated ligands, which facilitates intramolecular ...

The limitation for popular descriptions of alpha-relaxation temperature dependence [PDF]
arXiv, 2011 Applicability of three popular functions (Vogel-Fulcher-Tammann, double activation law and frustration-limited domains model) for the description of the temperature dependence of alpha-relaxation time tau_alpha is considered for three typical glass-formers (propylene carbonate, ethanol and picoline). Two first functions have three free parameters.

Geometric-algebraic approach to aqueous solutions of diprotic acids and its buffer mixtures [PDF]
arXiv, 2023 A closed-form analytical expression for $\ce{[H3O+]}$ has been obtained for aqueous solutions of diprotic acids and its soluble salts. This formula allows to calculate the pH of aqueous solutions of diprotic acids, their buffer solutions, and the titrations of these two by a strong base, from the values of p$K_1$, p$K_2$, and the effective ...
