Creutzfeldt-Jakob disease (CJD) is characterized by rapidly progressive dementia with a variety of neurological disorders and a fatal outcome. The authors present a case with visual disturbance as a leading symptom and rapid deterioration in global cognitive functions. The cerebrospinal fluid was positive for 14-3-3 protein, and diffusion-weighted magnetic(More)
A recent physiological finding of neural coding for border ownership (BO) that defines the direction of a figure with respect to the border has provided a possible basis for figure-ground segregation. To explore the underlying neural mechanisms of BO, we investigated stimulus configurations that activate BO circuitry through psychophysical investigation of(More)
Early intensive care for severe acute pancreatitis is essential for improving SAP mortality rates. However, intensive therapies for SAP are often delayed because there is no ideal way to accurately evaluate severity in the early stages. Currently, perfusion CT has been shown useful to predict prognosis of SAP in the early stage. In this presented paper, we(More)
BACKGROUND The long-term efficacy of infliximab (IFX) for patients with refractory ulcerative colitis (UC) is unclear. The aim of this study was to assess the long-term outcomes of IFX treatment in patients with refractory UC. METHODS Thirty-three patients with refractory UC who received IFX treatment at Kyoto University Hospital between 2003 and 2013(More)
Behçet's disease (BD) is a systemic vasculitis, while myelodysplastic syndrome (MDS) is a heterogeneous group of clonal hematologic disorders characterized by ineffective hematopoiesis. Some studies suggest a relationship between MDS and BD, especially intestinal BD, and trisomy 8 seems to play an important role in both diseases. There are several reports(More)
OBJECTIVE The objective was to investigate the relationship between prognosis in case of pancreatic cancer and perfusion in tissue surrounding pancreatic cancer using perfusion CT. METHODS We enrolled 17 patients diagnosed with inoperable pancreatic adenocarcinoma. All patients were examined by perfusion CT and then underwent chemotherapy using(More)
Recent physiological studies revealed that neurons in the macaque visual cortex encode the direction of a figure along a contour (border ownership, BO). Although their cortical mechanisms have not been clarified, a computational model for BO has suggested that surround modulation in early vision can play an important role. Here we examined psychophysically(More)
A number of cells in monkeys' V2 and V4 are selective for border-ownership (BO) that indicates the direction of figure with respect to the border [1]. A notable character of the cells that appears to be crucial for natural image processing is the consistent determination of BO for various stimuli. Each cell has preferred shapes, and is not capable of(More)
