BACKGROUND Sentinel-node navigation surgery (SNNS) for breast cancer and melanoma has been accepted as a reasonable oncologic surgery worldwide. On the other hand, in gastric cancers that do metastasize well to the lymph node, the use of SNNS has been approached with care and performed in only limited cases. Some obstacles still have to be overcome, such as(More)
To investigate the cardioprotective effects and mechanism of action of KR-32560 {[5-(2-methoxy-5-fluorophenyl)furan-2-ylcarbonyl]guanidine}, a newly synthesized NHE-1 inhibitor, we evaluated the effects of KR-32560 on cardiac function in a rat model of ischemia/reperfusion (I/R)-induced heart injury as well as the role antioxidant enzymes and pro-survival(More)
Meigs' syndrome is a benign ovarian tumor associated with ascites and pleural effusion. Elevated cancer antigen 125 (CA-125) in Meigs' syndrome is an unusual clinical condition reported in few cases. We report here on a 61-year-old woman who presented with dyspnea; in imaging assessment, a heterogeneous pelvic mass measuring 12 × 11 cm with ascitic fluid(More)
The cardioprotective effects of the novel sodium/hydrogen exchanger-1 (NHE-1) inhibitor KR-32560 {[5-(2-methoxy-5-fluorophenyl)furan-2-ylcarbonyl]guanidine} were studied in an anesthetized rat model of 30-min ischemia / 2.5-h reperfusion heart injury. KR-32560 (0.01 - 1 microM) dose-dependently inhibited NHE-1-mediated rabbit platelet swelling induced by(More)
A method of collision avoidance for point mass UAVs (own and intruder) with constant velocity is described in 3-D. This paper discusses en route aircraft which are assumed to be linked by real time data bases like ADS-B and can be considered as a constant velocity motion. The proposed approach uses probabilistic trajectory model supposed to have uncertain(More)
The development of an efficient catalytic activation (cleavage) system for C-H and C-C bonds is an important challenge in organic synthesis, because these bonds comprise a variety of organic molecules such as natural products, petroleum oils, and polymers on the earth. Among many elegant approaches utilizing transition metals to activate C-H and C-C bonds(More)
We evaluated the antiplatelet effects of two classes of ATP-sensitive potassium channel openers (K(ATP) openers) on washed human platelets, and the study's emphasis was on the role of mitochondrial K(ATP) in platelet aggregation. Collagen-induced platelet aggregation was inhibited in a dose dependent manner by lemakalim and SKP-450, which are potent(More)
Radix Salviae miltiorrhiza (RSM, 'Dansham' in Korea, 'Danshen' in Chinese), the root of Salviae miltiorrhiza Bunge (Labiate) has been used as Chinese fork medicine for the treatment of cardiovascular diseases such as angina pectoris, coronary heart disease, myocardial infarction, and hypertension. In the present study, we evaluated the inhibitory effects of(More)
OBJECTIVES This study was conducted to determine the number of hours worked per week by full-time wage workers by using the data of the Korean Labor and Income Panel Study (KLIPS), which represents the domestic urban area household, and to determine the association between weekly working hours and the level of self-rated health. METHODS We used data from(More)
