Background: Radical segmentectomy has been performed for small-sized non-small cell lung cancer (NSCLC). However, underestimation of mediastinal lymph node metastasis in the absence of hilar or interlobar metastasis (skip N2) affects surgical strategy. Our aim was to investigate preoperative and intraoperative predictors of skip N2 in clinical stage (c-stage) IA NSCLC.

Myristoylated alanine-rich C-kinase substrate as a prognostic biomarker in human primary lung squamous cell carcinoma.

To identify novel biomarkers for the diagnosis and prognosis of human primary lung squamous cell carcinoma (SCC), we compared the spectrum of proteins expressed in SCC and in the adjacent non-cancer tissue, using QSTAR Elite liquid chromatography with tandem mass spectrometry (LC-MS/MS), coupled with iTRAQ technology. We identified 410 proteins differentially expressed in more than 75% of patients, and validated the expression of candidate target proteins by immunohistochemistry. Based on the results of LC-MS/MS, Ingenuity Pathway Analysis and immunohistochemical analyses, myristoylated alanine-rich C-kinase substrate (MARCKS) (upregulated 2.

Does rich coronary collateral circulation distal to chronically occluded left anterior descending artery compete with graft flow?

Objectives: In coronary artery bypass grafting (CABG), graft flow distal to a mild stenosis can compete with relatively preserved native flow through the stenosis and the competition can result in graft stenosis. In chronic total occlusion (CTO), coronary collateral circulation, which is essential to maintain myocardial viability distal to CTO, varies in extent among patients and the extent can be scored by Rentrop grade in coronary angiography. We investigated whether rich collateral circulation distal to CTO competes with distally anastomosed graft flow in association with Rentrop grade.
