BACKGROUND: Recently, urinary tissue inhibitor of metalloproteinase-2 (TIMP-2) and insulin-like growth factor-7 (IGFBP-7), markers for G1 cell cycle arrest, have been identified and validated in predicting the development of acute kidney injury in critically ill patients. It is unknown, however, whether these two biomarkers could predict the development of delayed graft function (DGF) after kidney transplantation (KT). METHODS: This is a single-center, prospective, observational study...

Neutrophil gelatinase-associated lipocalin (NGAL, lipocalin 2 or LCN2) is an iron carrier protein whose circulating level is increased by kidney injury, bacterial infection and obesity, but its metabolic consequence remains elusive. To study physiological role of LCN2 in energy homeostasis, we challenged female Lcn2 knockout (KO) and wild-type (WT) mice with high fat diet (HFD) or cold exposure. Under normal diet, physical constitutions of Lcn2 KO and WT mice were indistinguishable. During HFD treatment, Lcn2 KO mice exhibited larger brown adipose tissues (BAT), consumed more oxygen, ate more food and gained less body weights as compared to WT mice...

BACKGROUND: Neutrophil gelatinase-associated lipocalin (NGAL) is a marker of both tissue injury and infection. Urine NGAL levels strongly predict acute kidney injury and mortality in patients with cirrhosis, but ascites NGAL is not well characterized. We hypothesized that ascites NGAL level is a marker of spontaneous bacterial peritonitis (SBP) and mortality risk in patients with cirrhosis. METHODS: Hospitalized patients with cirrhosis and ascites undergoing diagnostic paracentesis were prospectively enrolled and followed until death or discharge...

BACKGROUND: Neutrophil Gelatinase-Associated Lipocalin (NGAL) is an inflammatory protein with gaining increasing interest for its use as marker in blood and cerebrospinal fluid (CSF) for several chronic diseases. Its biochemical properties make it an attractive marker. However, changes in blood and CSF NGAL concentrations during the diurnal rhythm in the elderly are unknown. This information is important for its optimal use as marker in studies with older people. METHODS: Serial paired plasma and CSF samples were obtained from 8 healthy elderly males over a 30 hour period...

Background Information regarding urinary biomarkers in Mestizo and Afro-Latin-American patients is very limited. We investigated whether levels of urinary neutrophil gelatinase-associated lipocalin (NGAL), and monocyte chemoattractant protein 1 (MCP-1) are good biomarkers to differentiate patients with lupus nephritis among Latin-American systemic lupus erythematosus (SLE) patients. Methods SLE patients meeting the revised American College of Rheumatology classification criteria for SLE were recruited. Urinary levels of NGAL and MCP-1 were measured using a commercial ELISA kit...

BACKGROUND: The use of artificial colloids has declined in critical care, whereas they are still used in perioperative medicine. Little is known about the nephrotoxic potential in noncritically ill patients during routine surgery. The objective of this trial was to evaluate the influences of albumin 5% and balanced hydroxyethyl starch 6% (130/0.4) on renal function and kidney injury. METHODS: One-hundred urologic patients undergoing elective cystectomy were randomly assigned for this prospective, single-blinded, controlled study with two parallel groups to receive either albumin 5% or balanced hydroxyethyl starch 6% (130/0...

Myocardial infarction (MI) is accompanied by cardiac fibrosis, which contributes to cardiac dysfunction. Mineralocorticoid receptor (MR) antagonists have beneficial effects in patients with left ventricular (LV) dysfunction after MI. We herein investigated the role of the MR target NGAL (neutrophil gelatinase-associated lipocalin) in post-MI cardiac damages. Both higher baseline NGAL and a greater increase in serum NGAL levels during follow-up were significantly associated with lower 6-month LV ejection fraction recovery in a cohort of 119 post-MI patients, as assessed by cardiac magnetic resonance imaging...

OBJECTIVE: Tumor necrosis factor- (TNF-) related apoptosis-inducing ligand (TRAIL) is attracting attention for its role in the physiopathology of metabolic disease/diabetes. Evidence suggests that it might protect against metabolic abnormalities driven by obesity-induced dysregulated secretion of adipokines, but this role of TRAIL has not yet been fully established. On this basis, we aimed to investigate the potential association between TRAIL and adipokine levels in a cohort of subjects in which age/gender/hormonal interferences were excluded...

OBJECTIVES: Cold-inducible ribonucleic acid-binding protein (CIRP) has been identified to play a role in the antiapoptotic effect of hypothermia. We sought to investigate the renoprotection of CIRP in a rat model of deep hypothermic circulatory arrest. METHODS: Overexpression and knockdown of CIRP were achieved in vivo by directly injecting lentivirus vectors containing packaging lentivirus (pL)/internal ribosome entry site (IRES)/green fluorescent protein (GFP)-CIRP or pL/short hairpin RNA (shRNA)/F-cold inducible RNA binding protein (F-CIRP)-A into the renal parenchyma of rats 7 days before deep hypothermic circulatory arrest under the ultrasound guidance...
