Although statin use in patients with acute myocardial infarction (AMI) is mandatory, it has been suggested to be associated with new-onset diabetes mellitus (NODM). In real world practice, moderate-intensity statin therapy is more commonly used than high-intensity statin therapy. In this study, we investigated the impact of moderate-intensity pitavastatin (2 to 4 mg) compared with moderate-intensity atorvastatin (10 to 20 mg) and rosuvastatin (5 to 10 mg) on the development of NODM during a follow-up period of up to 3years...

The specific role of human epidermal growth factor receptor-2 (HER2) status in rectal cancers remains unclear. This study therefore aimed to explore clinicopathologic and molecular characteristics, and prognostic value of HER2-positivity in residual mid- and/or low-rectal cancers after preoperative chemoradiotherapy (CRT). Surgical specimens from 145 patients with residual rectal cancer after preoperative CRT between January 2006 and January 2011 were used to evaluate HER2 status. HER2 protein expression and gene amplification were determined using immunohistochemistry (IHC) and silver in situ hybridization (SISH) on whole tissue sections, respectively...

Visual evaluation of the surface anchoring energies in a nematic liquid crystal (LC) cell is characterized by the direction of the convection roll pattern that appears in the low-frequency conduction regime. The convection roll pattern in a twisted nematic LC (TNLC) cell is oriented perpendicular to the midplane LC director dominating the direction of convection flow, and its direction is determined by the relative surface anchoring energy between two surface boundaries. Thus the direction of the roll pattern generated at the TNLC cell with asymmetric LC alignment layers can provide information on the surface anchoring energies at the two boundaries...
