The present study was designed to examine the specificity of (3-adrenergic antagonists for al-, 192-adrenergic and 5HT1B-serotonergic receptors by the compe titive interaction with 1251-iodocyanopindolol (1251-ICYP) as a radioligand. The 81 -adrenoceptors were preferred by acebutolol, atenolol, betaxolol, practolol, and I-, dl and d-metoprolol, while(More)
Redox-active phenazinium salts bonded to amphiphilic polymer backbones are demonstrated to function as high-performance electron-transfer mediators in enzymatic bioanodes applicable to biofuel cells. The redox-active moieties could be easily tethered to the electrodes by physical adsorption of the hydrophobic regions of the polymer backbones onto the(More)
Rectal gastrointestinal stromal tumors (GISTs) are rare. Accordingly, their clinical features are not well-documented and optimal treatment has not been established. The objective of this study is to clarify the rates and patterns of recurrence after surgical resection of rectal GISTs, with a focus on outcomes and therapeutic modalities. The registry was(More)
