The aim of this study was to evaluate the utility of lymph node metastasis classification based on the number of positive stations in patients undergoing surgical management of esophageal cancer. Of 257 patients who underwent curative esophagectomy, 126 patients with lymph node involvement underwent assessment of nodal metastasis mode according to the 7th(More)
We reported a 69-year-old woman with multiple system atrophy (MSA), who had a heteroallelic missense mutation (G1874A, Gly-->Glu) in the exon 11 of the ceruloplasmin (Cp) gene. At the age of 64, she began to complain of progressive gait disturbance, which was resistant to anti-Parkinsonian drug treatment. Neurological examination revealed parkinsonism such(More)
An 80-year-old woman was admitted to our hospital because of developed sense of constriction in the trunk and gradually progressive numbness and muscle weakness in the upper and lower extremities. Cerebrospinal fluid analysis showed increased cell count and protein level. Gadolinium enhanced magnetic resonance imaging (MRI) of spine showed the enhancement(More)
This paper describes an extension of separable lattice 2-D HMMs (SL-HMMs) using state duration models for image recognition. SL-HMMs are generative models which have size and location invari-ances based on state transition of HMMs. However, the state duration probability of HMMs exponentially decreases with increasing duration, therefore it may not be(More)
