The present study used isolated rat hearts to investigate whether (1) Sheng-Mei-San (SMS), a traditional Chinese formulation comprising Radix Ginseng, Radix Ophiopogonis and Fructus Schisandrae, is protective against post-ischemic myocardial dysfunction, and (2) whether the cardioprotective effect of SMS is related to scavenging of hydroxyl radicals and(More)
To date, there are two pathways discussed as a mechanism of ischemic preconditioning. Activation of protein kinase C by ischemic preconditioning increases adenosine release. The increased adenosine further activates protein kinase C through adenosine A1 receptors, and activated protein kinase C induces an infarct size-reducing effect through the opening of(More)
Thirty-six patients who were admitted for surgical resection of leiomyosarcomas of the gastrointestinal tract to the Department of Surgery II, Kanazawa University Hospital, Kanazawa, Japan and its affiliates are included in the study. Follow-up data on survival is available for 32 patients. The clinico-pharmacologic variables, such as tumor site, tumor(More)
We examined whether pharmacological inhibition of glycogenolysis by N-methyl-1-deoxynojirimycin (MOR-14), a new compound which reduces the glycogenolytic rate by inhibiting the α-1,6-glucosidase activity of the glycogen-debranching enzyme, can protect the heart against postischemic left ventricular dysfunction. The hearts of male Sprague-Dawley rats were(More)
In rabbits, both the stimulation of α1-adrenoceptors and ischemic preconditioning (PC) reduce infarct size. One candidate for the mechanism of PC is noradrenaline (NA), which stimulates α1-adrenoceptors in the myocardium during PC. Opening of the KATP channel is considered to be another candidate for PC, since a KATP channel blocker, glibenclamide, blocks(More)
This paper presents a ring oscillator with the function of the oscillation controlled for wireless sensor systems (WSSs). The proposed oscillator consists of a NAND gate, 4 inverters, and 1-, 3-, 9-times buffer stage. Operation of it is controlled by the NAND gate. The oscillator can reduce the power loss because the oscillator is oscillated during only(More)
