PURPOSE As the proportion of early gastric cancer (EGC) has recently been increased, minimally invasive treatment is currently accepted as main therapy for EGC. Accurate preoperative staging is very important in determining treatment options. To know the accuracy of endoscopic ultrasonography (EUS), we compared the depth of invasion of the tumor with(More)
Gprotein-coupled receptor kinases (GRKs) are known to be involved in the development of cardiac hypertrophy. Their exact role and subcellular distribution during cardiac hypertrophy and failure remain to be elucidated. We examined expression and subcellular distribution of GRK2 and GRK5 in the left ventricle of female spontaneously hypertensive heart(More)
Focal adhesion kinase (FAK) and focal adhesion kinase-related nonkinase (FRNK) are likely involved in mechanical signaling during hypertension. We investigated expression, subcellular distribution, and phosphorylation of FAK, as well as FRNK in left ventricles of spontaneously hypertensive heart failure rats. Compared with normotensive controls, FAK and(More)
Beta-catenin is not only an adhering junction protein, but also the central player of the canonical Wnt signalling pathway. In order to investigate the roles of β-catenin in the mechanism of myocardial hypertrophy, we determined the expression and distribution of β-catenin in the cardiomyocytes of spontaneously hypertensive heart failure (SHHF) rats and(More)
PURPOSE Gastric cancer surgery is a common operation in East Asia, such as Korea and Japan, and there has been a significant increase in the need for this procedure due to the aging population. As a result, surgery for the treatment of gastric cancer for elderly patients is expected to increase. This study examined the effect of old age on gastric cancer(More)
This paper models the behavior of Ada tasks with Petri nets according to the semantics and the syntax of them, and this net is called an Ada net. Moreover our Ada net can improve the rendezvous model proposed by the S.M. Shatz as well as describing the task type. At the same time, we present the semantics and the syntax of computation tree logic with the(More)
The objective of the present study is to determine the role of prostaglandin E2 (PGE2) and downstream EP receptors in the development of human papillary thyroid carcinoma (PTC). A total of 90 thyroid specimens excised from patients undergoing total or subtotal thyroidectomy in the Department of General Surgery, the Fifth Affiliated Hospital of Sun Yat-sen(More)
