Diabetes mellitus, especially when complicated with decline of renal function due to diabetic nephropathy (DN), is associated with accumulation of advanced glycation end products (AGEs) exerting their adverse effects via receptor of AGE (RAGE). Soluble RAGE (sRAGE) is a truncated form of RAGE functioning as an inhibitor of AGE-mediated signalling. We studied relationships between sRAGE, renal function and genetic variability in the AGER gene in diabetic subjects. Study comprised a total of 265 diabetics (type 1 or 2 or LADA) with normoalbuminuria (n = 94) or DN (n = 171). sRAGE (assessed by ELISA) was significantly higher in DN than normoalbuminuria subjects (P = 0.007) and positively correlated with age, S-urea, S-creatinine and albuminuria and AGEs (determined spectrofluorimetrically), negatively with GFR (all P < 0.05); however, multivariate regression revealed that GFR was the only independent variable associated with sRAGE (P = 0.047). sRAGE did not correspond with carrier state of risk-haplotype copies (RAGE2) (P > 0.05). In conclusion, GFR is a principal determinant of sRAGE concentration and gradual sRAGE increase in subjects with advancing impairment of renal function is paralleled by AGEs.

Impact of kidney volume on incidence of in-hospital kidney-related adverse outcomes in patients with acute heart failure.

Background: Recent studies revealed an association between small kidney volume and progression of kidney dysfunction in particular settings such as kidney transplantation and transcatheter aortic valve implantation. We hypothesized that kidney volume was associated with the incidence of kidney-related adverse outcomes such as worsening renal function (WRF) in patients with acute heart failure (AHF).
Methods: This study was a single-center retrospective cohort study.
Acute kidney injury in paediatric kidney transplant recipients.

Acute kidney injury (AKI) in paediatric kidney transplant recipients is common. Infection including urinary tract infection (UTI) and rejection are the most common causes in children. Surgical complications often cause AKI early post-transplant, whereas BK polyomavirus nephropathy rarely occurs in the first month post-transplant.

Na-K-Cl cotransporters functions as an anion importers, regulating trans-epithelial chloride secretion, cell volume, and renal salt reabsorption. Loop diuretics, including furosemide, bumetanide, and torsemide, antagonize both NKCC1 and NKCC2, and are first-line medicines for the treatment of edema and hypertension. NKCC1 activation by the molecular crowding sensing WNK kinases is critical if cells are to combat shrinkage during hypertonic stress; however, how phosphorylation accelerates NKCC1 ion transport remains unclear.

Membrane incompatibility poses significant health risks, including severe complications and potential fatality. Surface modification of membranes has emerged as a pivotal technology in the membrane industry, aiming to improve the hemocompatibility and performance of dialysis membranes by mitigating undesired membrane-protein interactions, which can lead to fouling and subsequent protein adsorption. Affinity energy, defined as the strength of interaction between membranes and human serum proteins, plays a crucial role in assessing membrane-protein interactions.

School of Cardiovascular and Metabolic Health, University of Glasgow, Glasgow, UK.
Renal ischaemia due to renal artery stenosis produces two differing responses - a juxtaglomerular hypertensive response and cortical renal dysfunction. The reversibility of renal impairment is not predictable, and thus renal revascularisation is controversial. This study aims to test the hypothesis that the hypertensive response to renal ischaemia reflects viable renal parenchyma, and thus could be used to predict the recovery in renal function.
