Hydrogen Sulfide Delivery in Sulfurous Thermal Waters: Saturnia as a Translational Model for Gasotransmitter Pharmacology—A Narrative Review

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background Hydrogen sulfide (H2S) is an endogenous gasotransmitter regulating redox balance, inflammation, and vascular tone, but reproducing the spatial and kinetic features of endogenous production remains challenging. We examine sulfurous thermal waters as natural contexts of sustained H2S exposure, using the Saturnia springs (Tuscany ...

Understanding Mass Spectrometry: From Ion Generation to Spectral Interpretation

Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT This tutorial provides a structured introduction to mass spectrometry (MS), with particular emphasis on electrospray ionization (ESI)–based measurements. It is intended to support researchers from chemistry and related disciplines in developing a coherent understanding of MS principles, instrumentation, and data interpretation.

Liebig Review: Essential and Beneficial Elements in the Regulation of Cadmium Uptake and Tolerance in Crop Plants

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 4, Page 429-444, August 2026.
ABSTRACT Cadmium (Cd2+) contamination in agricultural soils has been reported to pose risks to crop productivity, food safety, and human health. This review synthesizes current knowledge on the mechanisms by which essential (S, Zn, Fe, Mg, K, Ca) and beneficial (Si, Se, rare earth elements) elements mitigate Cd2+ toxicity in plants.

Centennial‐scale phosphorus accumulation drives regeneration and internal loading in a boreal lake

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Legacy anthropogenic phosphorus (P) accumulated in sediments drives internal P loading in eutrophic lakes. However, predicting the temporal response of internal P loading to the external loading reduction is difficult due to the complexity of sedimentary P cycling. In this study, we use geochemical profiles obtained from a 180‐cm sediment core

Metabolic Regulation of Macrophages in Health and Disease

MedComm, Volume 7, Issue 8, August 2026.
Extracellular metabolites drive metabolic rewiring of glucose, lipid, and amino acid pathways in macrophages, steering their polarization toward pro‐ or anti‐inflammatory phenotypes and shaping a wide range of disease processes. Macrophages from different tissues display distinct metabolic signatures, and therapeutic strategies that target these ...

Nucleotide Metabolism in Health and Disease

MedComm, Volume 7, Issue 8, August 2026.
Nucleotide metabolism, including de novo synthesis, salvage pathways, and catabolism, when dysregulated contributes to cancer, immune disorders, metabolic and urological diseases, and radiation injury. Metabolites such as adenosine, cGAMP, NAD, and cAMP and enzymes like RNR are promising therapeutic targets and biomarkers.
