OBJECT Following stereotactic radiosurgery (SRS), we examined how to differentiate radiation necrosis from recurrent malignant glioma using positron emission tomography (PET) with 11C-methionine (Met). METHODS Met-PET scans were obtained from 11 adult cases of recurrent malignant glioma or radiation injury, suspected on the basis of magnetic resonance(More)
Two patients with acute embolic occlusion of the intracranial internal carotid artery and the lenticulostriate arteries were treated by local intraarterial fibrinolysis using tissue plasminogen activator. Although fibrinolysis started within 2.5 hours from the ictus, extravasation of the contrast medium from the lenticulostriate arteries occurred in the(More)
 Background: A dural arteriovenous fistula (AVF) involving the transverse-sigmoid (T-S) sinus which is occluded at its proximal and distal ends i.e., an isolated sinus, runs the risk of haemorrhaging or causing serious neurological deficits as a result of its retrograde leptomeningeal venous drainage. While lesions of this type have not been considered to(More)
BACKGROUND & AIMS A Th1 clone, II-6, established from an autoimmune gastritis BALB/c mouse that underwent thymectomy 3 days after birth, recognized a 15 mer peptide constructing the alpha subunit of H+, K(+)-adenosine triphosphatase as antigen and induced gastritis in nu/nu mice by adoptive transfer. The aim of this study was to examine the molecular(More)
BACKGROUND AND PURPOSE The inferior petrosal sinus (IPS) is the main transvenous access route used to examine or treat lesions involving the cavernous sinus. To carry out these procedures successfully, one must have a detailed knowledge of the anatomy of the venous system around the junction of the IPS and the internal jugular vein (IJV). MATERIALS AND(More)
1. The aim of the present study was to characterize the subtypes of bradykinin (BK) receptors that evoke the relaxation and contraction induced by BK and to identify the main contracting and relaxing factors in isolated porcine basilar artery by measuring changes in isometric tension and a thromboxane (TX) metabolite. 2. Endothelial denudation completely(More)
PURPOSE A new hypoxic cell sensitizer has been synthesized; this is a 2-nitroimidazole nucleoside analog having erythritol as a sugar moiety at the N-1 position of the imidazole ring (RP-343). Its possibility as a potent hypoxic cell sensitizer was compared with those of RP-170 and etanidazole. METHODS AND MATERIALS Radiosensitization was tested in two(More)
UNLABELLED BACKGROUND" Human thymic stromal lymphopoietin (TSLP) is expressed in the human asthmatic lung and activates dendritic cells (DCs) to strongly induce proallergic T-helper type 2 (Th2) cell responses, suggesting that TSLP plays a critical role in the pathophysiology of human asthma. Th2 cells are predominantly involved in mild asthma, whereas a(More)
We have reported that dietary magnesium (Mg) deficiency induced both histaminaemia and hypomagnesaemia in rats. In this study, the effects of dietary Mg deficiency on the reactivity of the isolated thoracic aorta to some vaso-active amines were studied ex vivo. Adult male Wistar rats were fed on a Mg-deficient diet (Mg 0.001%) and a control diet (Mg 0.07%)(More)
Human thymic stromal lymphopoietin (TSLP) promotes CD4(+) T-cell proliferation both directly and indirectly through dendritic cell (DC) activation. Although human TSLP-activated DCs induce CD8(+) T-cell proliferation, it is not clear whether TSLP acts directly on CD8(+) T cells. In this study, we show that human CD8(+) T cells activated by T-cell receptor(More)
