Analysis of the flavonoid component of bioactive New Zealand mānuka (Leptospermum scoparium) honey and the isolation, characterisation and synthesis of an unusual pyrrole [PDF]

open access: yes, 2013
The flavonoid components of New Zealand mānuka (Leptospermum scoparium) honey have been quantified in a series of 31 honeys of varying non-peroxide antibacterial activity to clarify discrepancies between previous studies reported in the literature. Total

Tamm–Horsfall protein in humane urine: sex-dependent differences in the excretion and N-glycosylation pattern

open access: yesScientific Reports, 2023
Tamm–Horsfall protein (THP) is a highly N-glycosylated protein from epithelial cells of the ascending limb of Henle loop. It is secreted into the urine as part of the innate immune response against uropathogenic pathogens.

Surface Tension of Electrolyte Solutions: A Self-consistent Theory

open access: yes, 2014
We study the surface tension of electrolyte solutions at the air/water and oil/water interfaces. Employing field-theoretical methods and considering short-range interactions of anions with the surface, we expand the Helmholtz free energy to first-order ...

Cellular microenvironment of erythropoietin‐producing cells in hypoxic and injured mouse kidneys

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 2236-2267, 1 April 2026.
Abstract The main sources of circulating erythropoietin (Epo) in the adult are kidney Norn cells, a recently identified interstitial cell type capable of becoming renal Epo‐producing (REP) cells following a local decrease in tissue oxygenation. REP cells are restricted to small clusters in the corticomedullary border region, suggesting that their ...

Interplay between uromodulin excretion and water balance in the general adult population

open access: yesPhysiological Reports, Volume 14, Issue 7, April 2026.
Abstract Uromodulin is a kidney‐specific protein that is excreted in the normal urine. Factors regulating its excretion are unknown. Conflicting studies suggest that water balance may influence uromodulin excretion which, in turn, may cooperate with vasopressin to increase water reabsorption in the distal nephron.

Augmenting the Endogenous RBM3 Response Protects Against Burn‐Induced Acute Kidney Injury by Enhancing Macrophage‐Mediated Resolution of Inflammation

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
This study reveals that augmenting the RNA‐binding protein RBM3 ameliorates burn‐induced acute kidney injury (AKI). RBM3 overexpression reprograms pro‐inflammatory M1 macrophages toward a pro‐resolving M2 phenotype, enhancing their capacity for efferocytosis.
