The purpose of this in vitro study was to compare the effect staining, glazing, and polishing on wear behavior stabilized zirconia with 5 mol% yttrium oxide (5Y-TZP) opposing 5Y-TZP, leucite-reinforced ceramic (LC), lithium disilicate (LD), microhybrid composite resin (MCR). Hemispheres 5Y-TZP were divided into six groups (n = 10) according finishing procedure: C (control), S (staining), G (gla...

Implantable cardioverter-defibrillators (ICDs) are critical for preventing sudden cardiac death (SCD) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC), but differences their utilization across North America and Europe unknown. To identify cross-national both of primary prevention ICDs survival free from arrhythmia (VA) ARVC. This was a retrospective analysis ARVC without ...

Oxaliplatin (Oxa) treatment to SH-SY5Y human neuroblastoma cells has been shown by previous studies to induce oxidative stress, which in turn modulates intracellular signaling cascades resulting in cell death. While this phenomenon of Oxa-induced neurotoxicity is known, the underlying mechanisms involved in this cell death cascade must be clarified. Moreover, there is still little known regardi...

Arsenic trioxide (As(2)O(3)) has anticancer properties; however, its use also leads to neuro-, hepato- or nephro-toxicity, and therefore, it is important to understand the mechanism of As(2)O(3) toxicity. We studied As(2)O(3) influence on intracellular calcium ([Ca(2+)](i)) homeostasis of human neuroblastoma SY-5Y and embryonic kidney cells (HEK 293). We also relate the As(2)O(3) induced [Ca(2+...

We present an elementary inductive proof which Euler could have obtained, for the corresponding result as the title indicates, had he refined a bit his proof for Fermat’s assertion on representing primes as two squares. It is really a pleasure to start with the story told by Cox in the nice book [2]. All letters in this note stand for nonnegative integers, unless otherwise specified. 1. Fermat ...
