The aim of the study was to investigate whether inhibition of dorsal spinocerebellar tract (d.s.c.t.) cells evoked from group I afferents is mediated by the same interneurones which mediate the non-reciprocal inhibition of hind-limb motoneurones. The origin of inhibition of d.s.c.t. cells from group I afferents was compared in intact preparations, after(More)
The topographical distribution of interneurones mediating disynaptic inhibition of dorsal spinocerebellar tract (d.s.c.t.) cells from group I muscle afferents in the cat was investigated using both physiological and morphological techniques. Lesions of either the dorsal funiculi or of the lateral and ventral funiculi were made between L4 and L5 segments in(More)
The effects of stimulation of the caudate nucleus were investigated in alert cats, with special reference to the induction of eye and head movements. Stimulation of caudal portions of the caudate nucleus on one side with trains of current pulses induced gaze shifts towards the contralateral side. When the head of the animal was restrained, the majority of(More)
An attempt was made to re-examine regional differences in the cat caudate nucleus as to the effectiveness in inducing contraversive head-turning by electrical stimulation and to analyze the time course of head-turning quantitatively. In 5 of the total 9 cats, the right sensorimotor cortex and its surrounding areas had been ablated chronically. While the(More)
The purpose of this study was to compare the parameters of the dose-volume histogram (DVH) between proton beam therapy (PBT) and X-ray conformal radiotherapy (XCRT) for locally advanced non-small-cell lung cancer (NSCLC), according to the tumor conditions. A total of 35 patients having NSCLC treated with PBT were enrolled in this analysis. The numbers of(More)
BACKGROUND Proton-beam therapy (PBT) provides therapeutic advantages over conformal x-ray therapy in sparing organs at risk when treating esophageal cancer because of the fundamental physical dose distribution of the proton-beam. However, cases with extended esophageal lesions are difficult to treat with conventional PBT with a single isocentric field, as(More)
Surgical resection is the first choice for treatment of a thymic carcinoid tumor and radiotherapy is often performed as adjuvant therapy. Here, we report a case of an unresectable and chemoresistant thymic carcinoid tumor that was treated successfully using standalone proton beam therapy (PBT). The patient was a 66-year-old woman in whom surgical resection(More)
