The aim of this study was to evaluate the accuracy of multiple detector computed tomography (MDCT) in the preoperative staging of gastric cancer, prospectively comparing CT findings with pathological findings at surgery, in a single-center study. A total of 19 consecutive patients with primary cancer recruited between March and July 2014 were submitted to preoperative MDCT staging according to a standard protocol. All diagnostic procedures were performed by dedicated radiologists who were unaware of the final pathological results. Subsequently, 16 patients underwent surgical treatment and 15 were finally included in the study. The primary tumor was detected at CT in all 15 cases. CT results for T staging were in agreement with pathological findings in 12 of 15 cases, with overall accuracy of 80%. Stage-specific sensibility was high for advanced stages (sensibility for T1, T3, and T4 resulted 60%, 85.7%, and 100%, respectively), while earlier stages showed higher specificity (specificity for T1, T3, and T4 resulted 100%, 75%, and 91.7%, respectively). Overall N staging accuracy was 86.7%, with 13 of 15 patients correctly staged. Stage-specific sensibility was 75% for N0 and 100% for N3, while specificity was 100% for N0 and lower for advanced stages. Accuracy for peritoneal involvement was 100%. Our findings show a good performance of the diagnostic protocol performed with MDCT tested in this study.

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton ...

Effects of Karate Training on Basic Motor Abilities of Primary School Children

“You never attack first in karate” might be the best conclusion of karate, which is a martial art practiced typically without weapons. It’s reported that karate has a long history for several hundred years, but the modern karate was spread to the whole Japan from Okinawa in the early part of 20th century. Now it has become one of the most widely practiced martial art forms in the world. Usually, it’s divided into Kihon, Kata and Kumite. As for the beginners, Kihon is more suitable for them because it involves basic techniques. Due to karate consists of dynamic offensive and defensive techniques using all parts of the body to their maximum advantage, the best understanding of true karate practice is the perfection of oneself through the perfection of the art. It not only develops coordination, quickens reflexes, and builds stamina, but also develops composure, a clearer thought process, deeper insight into one’s mental capabilities, and more self-confidence. So many researchers stu...
