The prepositus hypoglossi nucleus (PHN) is thought to be a neural structure involved in transforming eye or head velocity signals into eye position signals for horizontal eye movements. In this study, we investigated the relationship between electrophysiological membrane properties and expression patterns of cellular markers for excitatory and inhibitory(More)
The identification and characterization of excitatory and inhibitory neurons are significant steps in understanding neural network functions. In this study, we investigated the intrinsic electrophysiological properties of neurons in the prepositus hypoglossi nucleus (PHN), a brainstem structure that is involved in gaze holding, using whole-cell recordings(More)
BACKGROUND Amino-acid transporters are necessary for the tumour cell growth and survival, and have a crucial role in the development and invasiveness of cancer cells. But, it remains unclear about the prognostic significance of L-type amino-acid transporter 1 (LAT1), system ASC amino-acid transporter-2 (ASCT2), and xCT expression in patients with tongue(More)
Unipolar brush cells (UBCs) are excitatory interneurons in the granular layer of the cerebellar cortex, which are predominantly distributed in the vestibulo-cerebellar region. The unique firing properties and synaptic connections of UBCs may underlie lobular heterogeneity of excitability in the granular layer and the susceptibility to ischemia-induced(More)
The aim of this study is to evaluate the clinicopathological significance of L-type amino acid transporter 1 (LAT1) expression in patients with advanced laryngeal squamous cell carcinoma (LSCC). A total of 73 patients with advanced LSCC were retrospectively reviewed. Tumor sections were stained by immunohistochemistry for LAT1, 4F2hc, system ASC amino acid(More)
Pyriform sinus fistula is a rare clinical entity and the precise origin remains controversial. The fistula is discovered among patients with acute suppurative thyroiditis or deep neck infection of the left side of the neck and is usually located in the left pyriform sinus. To the best of our knowledge, only a single tract has been reported to be responsible(More)
The expression of L-type amino acid transporter 1 (LAT1) is correlated with tumor cell growth and survival. However, the clinicopathological significance of LAT1 expression in adenoid cystic carcinoma (ACC) remains to be elucidated. The aim of this study is to investigate the clinicopathological significance of LAT1 expression in ACC. A total of 30 patients(More)
In our previous study on the prepositus hypoglossi nucleus (PHN), we found a neuronal subtype exhibiting a specific firing pattern in which the first interspike interval (ISI) was longer than that of the second, designated FIL (first interspike interval long) neurons. In the present study, we explored the ionic mechanisms underlying this firing pattern(More)
The moving mirror model is designed to extract essential features of the black hole formation and the subsequent Hawking radiation by neglecting complication due to a finite curvature. We extend this approach to dynamically treat back reaction against the mirror motion due to Hawking radiation. It is found that a unique model in two spacetime dimensions(More)
