A case of massive intestinal blood loss from multiple duodeno-jejunal diverticula is described. A 39-year-old man was referred to our hospital because of recurrent bloody stool and worsening anemia. Upper and lower endoscopy, selective abdominal angiography, and radionuclide scanning were performed to seek the cause of the intestinal bleeding, but none of(More)
Serotonin (5-hydroxytriptamine; 5-HT), which is stored in platelets, is known to induce vasoconstriction and promote platelet aggregation. More recent studies suggest that serotonin also plays a role in organ injury after ischemia and reperfusion. The purpose of this study was to characterize the role of 5-HT and platelet function in the pathogenesis of(More)
We propose a triplexer in a low temperature co-fired ceramic substrate for ultra-wideband (UWB) and 2.4GHz wireless systems. This triplexer can be applied to the band of 2.4GHz wireless systems (2.4 2.5GHz), the band group 1 (3.168 4.752GHz) of multiband orthogonal frequency-division multiplexing UWB wireless systems, and the band groups 3 and 4 (6.336(More)
Recently, compact wireless modules using low temperature co-fired ceramic (LTCC) technology are widely used for the wireless systems such as mobile phones, Bluetooth, and wireless local-area networks(Lin et al.,2004; Wang et al.,2005). Fig.1 shows the general structure of the compact wireless modules using the LTCC technology. The modules consist of an LTCC(More)
