The subcellular localization of N-formylmethionyl-leucyl-phenylalanine (fMLP) receptors in human neutrophils was investigated. The fMLP receptor was detected with a high-affinity, photoactivatable, radioiodinated derivative of N-formyl-methionyl-leucyl-phenylalanyl-lysine (fMLFK). Neutrophils were disrupted by nitrogen cavitation and fractionated on Percoll density gradients. fMLP receptors wer...

This study investigated the distribution of neutrophil gelatinase-associated lipocalin (NGAL) and neutrophil gelatinase-associated lipocalin receptor (NGALR) in human embryonic, fetal and normal adult tissues. Tissue microarray technology was used to perform immunohistochemical examination on human embryos, fetuses at 4-22 weeks of gestation and a...

Cardiac surgery-associated acute kidney injury (AKI) is common and carries a poor prognosis. Hemodynamic and inflammatory factors and the release of labile iron, contributing to oxidation from reactive oxygen species are among the major determinants of cardiac surgery-associated AKI. The diagnosis of AKI is typically delayed because of the limitations of currently used clinical biomarkers indic...

Lipocalin 2 (LCN2), a multifunctional secretory protein known as neutrophil gelatinase-associated lipocalin (NGAL), is expressed in a variety of cancers. However, little is known about the biological functions of NGAL in the development of lung adenocarcinoma. In the present study, we primarily found that NGAL expression was up-regulated in human lung adenocarcinoma tissues. Additionally, deple...

Background: Routine diagnostic methods of Vesicoureteral reflux (VUR) are invasive and can cause exposure to radiation and may increase risk of urinary tract infections. Therefore, introducing reliable, non invasive methods might be more interested in pediatric nephrology. The objective of this perspective case control study was to evaluate the prognostic value of urinary neutrophil-gelatinase ...
