BACKGROUND Tumor recurrence is the most common cause of treatment failure, especially after complete resection of pathological stage N2 non-small cell lung cancer (NSCLC). In this study, we investigated the clinicopathological characteristics in order to identify independent risk factors for postoperative recurrence. METHODS Between January 2001 and December 2013, 96 patients who underwent su...

Traits related to nitrogen fixation may be used as indirect selection criteria foraflatoxin resistance in peanut. The aim of this study was to investigate therelationship between N2 fixation traits and aflatoxin contamination in peanut underdifferent drought conditions. Eleven peanut genotypes were evaluated under threewater regimes for two seasons in the field. Data were observed on kernel inf...

The Charge transport in desoxyribonucleic acid (DNA) is being intensively investigated in view of its biological implications in damage and repair, protein bonding, and envisioned integration in future (bio)electronics or DNA-based chips. Notwithstanding, despite sustained efforts to unveil the nature and range of charge transfer in these biomolecules, present knowledge lacks stable foundations...

OBJECTIVE To reveal the incidence and clinical significance of mediastinal nodal metastases without N1-station nodal metastases ('skip-N2 metastases') in non-small cell lung cancer (NSCLC). METHODS A total of 450 NSCLC patients who underwent tumor resection with a systemic mediastinal nodal dissection were retrospectively reviewed. p53 status and proliferative activity represented as prolifer...
