De novo or Salvage? Nucleotide Availability as a Driver of Bacterial Adaptation and Virulence

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Bacterial pathogens survive in different host environments by switching between making nucleotides by de novo synthesis and scavenging them from the host. This flexibility supports growth and virulence making nucleotide metabolism an attractive therapeutic target.

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.

Hydrothermally Synthesized Cerium Phosphate with Functionalized Carbon Nanofiber Nanocomposite for Enhanced Electrochemical Detection of Hypoxanthine

Chemosensors
This work presents the detection of hypoxanthine (HXA), a purine derivative that is similar to nucleic acids who overconsumption can cause health issues, by using hydrothermally synthesized cerium phosphate (CePO4) followed by a sonochemical approach for

Effects of Coffee Decaffeination on Beverage Bioactives, Antioxidant Activity, and Lipid Metabolism in Hyperlipidemic Rats

Journal of Food Science, Volume 91, Issue 8, August 2026.
ABSTRACT The aim of this study was to evaluate the effect of chemical decaffeination on two coffee species (Coffea arabica and Coffea canephora) in terms of the chemical composition of filtered coffee beverages and their influence on lipid profile and oxidative stress in rats with diet‐induced hyperlipidemia. Rats (n = 30) were divided into six groups:

Metabolic Signatures of Aging and Gametogenesis in Hydra oligactis

Aging Cell, Volume 25, Issue 8, August 2026.
Hydra oligactis undergoes cold‐induced sexual differentiation and aging, culminating in death. GC–MS‐based metabolite profiling revealed signatures of gametogenesis, for example, polyamine accumulation, and of aging, such as loss of cytoprotection and neurotransmitter function, including taurine depletion.

Thrombocytosis and the generation of platelet‐derived microparticles in the pathophysiology of sickle cell disease

British Journal of Haematology, Volume 209, Issue 2, Page 420-431, August 2026.
Thrombocytosis is associated with an increased production of platelet‐derived microparticles from activated platelets, which contribute to vaso‐occlusion in sickle cell disease by perpetuating the cycle of inflammation, procoagulant state and endothelial dysfunction.

Possibilities of the use of fast scan voltammetry in simultaneous determination of purines at carbon fiber ultramicroelectrodes

Journal of the Brazilian Chemical Society, 2000
Hypoxanthine, xanthine and uric acid are purines present in extracellular fluids that can be used as metabolic markers, in evaluation of meat conservation and other applications. Voltammetric studies were performed in order to investigate the possibility

Pomegranate Peel Polyphenol Extract Ameliorates Hyperuricemia by Inhibiting Uric Acid Synthesis and Reabsorption

Chemical Biology &Drug Design, Volume 108, Issue 2, August 2026.
The graphical abstract illustrates the action mechanisms through which PPE alleviates HUA by inhibiting XOD activity, and by suppressing the PI3K‐AKT signaling pathway to downregulate the expression of the urate reabsorption transporters URAT1 and GLUT9, thereby promoting renal UA excretion and attenuating renal injury.

Clinical Implications and Research Progress of Salivary Biomarkers for Endocrine and Metabolic Disorders

Diabetes, Obesity and Metabolism, Volume 28, Issue 8, Page 6561-6575, August 2026.
ABSTRACT Aims Similar to blood, saliva contains a broad range of biomarkers and may offer a non‐invasive, repeatable specimen for endocrine and metabolic assessment. This review aims to synthesise and evaluate recent advances in the clinical translation of salivary biomarkers, while providing a critical assessment of the diagnostic reliability and ...
