OBJECTIVE: Carperitide, alpha-human atrial natriuretic peptide, is used in expectation of protecting the kidney during sepsis in internal care unit; however, the detailed mechanism of action has not been clarified yet. As septic acute kidney injury (AKI) does not induce characteristic histological damage, we aimed assess the effects of carperitide treatment on the decline of renal function during lipopolysaccharide-induced AKI by using real-time intravital imaging technique. DESIGN AND METHOD: The renal function was analyzed by the bolus-shot FITC-inulin kinetics method that visualizes the tubular flow after free filtration from glomeruli...

OBJECTIVES: Serum creatinine (SCr) is a late marker of acute kidney injury (AKI) due to the lag time between initiating injury and loss of function. We assessed the ability of urinary interleukin-18 (IL-18), kidney injury molecule-1 (KIM-1), and neutrophil gelatinase-associated lipocalin (NGAL) to predict AKI in critically ill children with circulatory collapse. METHODS: Serum creatinine, estimated creatinine clearance (eCrCL), urine IL-18, KIM-1, and NGAL values were measured in 86 children with circulatory collapse on the day of admission, and the results were compared with those obtained 6 days later...

BACKGROUND: Acute kidney injury (AKI) caused by drug and toxicant ingestion is a serious clinical condition associated with high mortality rates. We currently lack detailed knowledge of the underlying molecular mechanisms and biological networks associated with AKI. In this study, we carried out gene co-expression analyses using DrugMatrix-a large toxicogenomics database with gene expression data from rats exposed to diverse chemicals-and identified gene modules associated with kidney injury to probe the molecular-level details of this disease...

BACKGROUND & AIMS: In patients with cirrhosis of the liver, acute kidney injury (AKI) is classified into 3 stages. Recent studies indicate that there are 2 subgroups of stage 1 disease, associated with different outcomes and serum levels of creatinine (sCr): stage 1A (sCr <1.5 mg/dL) and stage 1B (SCr ≥1.5 mg/dL). We performed a prospective study to validate, in a large series of patients with cirrhosis, the association between this new description and patient outcomes, as well as assess the relationship between AKI stage and the presence of acute-on-chronic liver failure (ACLF)...

Acute kidney injury (AKI) is a recognized complication post-endovascular aneurysm repair (EVAR). Neutrophil gelatin-associated lipocalin (NGAL), interleukin 18 (IL-18), and retinol-binding protein are emerging urinary biomarkers that have shown promise in detecting subclinical and clinical renal impairment. In this study, we assessed changes in these urinary biomarkers as well as serum creatinine (SCr) in patients undergoing EVAR. Urine samples were collected prospectively at 5 time points for each recruited patient: pre-EVAR (baseline) and 6, 12, 24, and 48 hours after the procedure for serial assessment of urinary biomarkers...

Resveratrol (RSV), a polyphenolic compound derived from red wine, inhibits the proliferation of various types of cancer. RSV induces apoptosis in cancer cells, while enhancing autophagy. Autophagy promotes cancer cell growth by driving cellular metabolism, which may counteract the effect of RSV. The present study aimed to elucidate the correlation between RSV and autophagy and to examine whether autophagy inhibition may enhance the antitumor effect of RSV in endometrial cancer cells. Cell proliferation, cell cycle progression and apoptosis were examined, following RSV exposure, by performing MTT assays, flow cytometry and annexin V staining, respectively, in an Ishikawa endometrial cancer cell line...
