Goals of this study were to analyze the ability of mass spectrometry serum profiling to distinguish non-small cell lung adenocarcinoma from squamous cell carcinoma patients and healthy controls. Sera were obtained from 19 adenocarcinoma patients, 24 squamous cell carcinoma patients, and 21 controls. Identifications of significant mass-to-charge ratio (m/z)(More)
This study evaluated the usefulness of electrospray mass spectrometry to distinguish sera of early-stage pancreatic cancer patients from disease-free individuals. Sera peak data were generated from 33 pancreatic cancer patients and 30 disease-free individuals. A "leave one out" cross-validation procedure discriminated stage I/II pancreatic cancer versus(More)
OBJECTIVE The aim of this study is to identify biomarkers in sera of pancreatic cancer patients using mass spectrometry (MS) approaches. METHODS Sera from patients diagnosed with pancreatic adenocarcinoma and sera from normal volunteers were subjected to gel electrophoresis to resolve and quantify differences in protein levels. Protein bands that differed(More)
Doublecortin-like kinase 1 (DCLK1) is a putative pancreatic stem cell marker and is upregulated in pancreatic cancer, colorectal cancer, and many other solid tumors. It marks tumor stem cells in mouse models of intestinal neoplasia. Here we sought to determine whether DCLK1 protein can be detected in the bloodstream and if its levels in archived serum(More)
Hemorrhagic complications are common in patients placed on extracorporeal life support (ECLS), especially in those who have additional risk factors. Several centers use epsilon-aminocaproic acid (EACA) in their high-risk ECLS patients in an attempt to decrease the incidence of such complications, despite the fact that no controlled trials have been(More)
The impact of extracorporeal membrane oxygenation (ECMO) on neonatal leukocyte content and function was examined in six patients. Patients were treated with ECMO for a mean of 134 h (range 44-246 h). Absolute neutrophil counts decreased from 14679 +/- 2291/mm3 to 7791 +/- 1672/mm3 after 2 h of ECMO. However, neutrophil phagocytosis and oxidative burst(More)
The anti-inflammatory selenium compounds, ebselen (2-phenyl-1,2-benzisoselenazol-3[2H]-one) and selenite, were found to alter the DNA binding mechanisms and structures of cysteine-rich zinc-finger transcription factors. As assayed by DNase I protection, DNA binding by TFIIIA (transcription factor IIIA, prototypical Cys(2)His(2) zinc finger protein), was(More)
Mercury has harmful effects in both rodents and humans. In rodent tissue culture cells exposed to HgCl(2), the metal ions were observed to concentrate in cell nuclei and to associate with chromatin. Thus, transcription factors and other proteins associated with chromatin are possible targets of mercuric ion toxicity. In this study, mercuric ions were found(More)
OBJECTIVE Inhaled nitric oxide (iNO) improves oxygenation and reduces the need for extracorporeal membrane oxygenation in infants with severe persistent pulmonary hypertension of the newborn (PPHN). The effectiveness of iNO in the treatment of moderate PPHN has not been adequately defined. We therefore conducted a randomized, prospective multicenter study(More)
