There has been no report for the expression of cyclooxygenase-2 (COX-2) and its clinicopathologic and biologic significance in ampulla of Vater cancer. This study was aimed for the clarification of COX-2 expression and its biologic roles in ampulla of Vater cancer. Fourty-six patients with ampulla of Vater cancer were enrolled and their COX-2 expression and clinicopathologic features were analy...

OBJECTIVE To investigate the long-term outcomes of supracricoid partial laryngectomy with cricohyoidoepiglottopexy (CHEP) and its modified version, in which we reserve the poster inferior borders of both thyroid cartilage laminas to protect swallowing function. METHODS This retrospective survival analysis was performed in 86 patients, wherein 46 undergoing CHEP and 40 undergoing modified CHEP...

When testing the null hypothesis that treatment arm-specific survival-time distributions are equal, the log-rank test is asymptotically valid when the distribution of time to censoring is conditionally independent of randomized treatment group given survival time. We introduce a test of the null hypothesis for use when the distribution of time to censoring depends on treatment group and surviva...

Pearson differential equation‎. ‎This distribution is also obtained from a compounding mixture of‎ ‎distributions‎. ‎Moments‎, ‎inequality measures‎, ‎uncertainty measures and reliability measures are theoretically established‎. ‎Characterizations of MLBXII distribution are also studied via different techniques‎. ‎Parameters of MLBXII dist...

PurposeIt is not known whether donor-transmitted coronary artery (DTCAD) disease after heart transplantation (HT) and its severity have prognostic implications. Our aim to assess if patients with multivessel significant-DTCAD (s-DTCAD) left anterior descendent (LAD) s-DTCAD worse prognosis at long-term follow-up.MethodsRetrospective study of HT > 18-year-old between 2008-2018 in 11 centers Spai...

in the present study, five log-normal models, normal model (n), and two four- parameter models namely gompertz (g) and fredlund (fr) were tested on 71 psd data from 10 soil textural classes. the jaky (j) and fr models had the smallest and largest r2 values for all of the soils, respectively. the results of comparing the n and simple log-normal (sl) models showed that the accuracy of the n model...
