A pilot study to assess the origin of the spectral power increases of heart rate variability associated with transient changes in the R-R interval.

Spectral analysis of heart rate variability (HRV) is used to assess cardiovascular autonomic function. In the power density spectrum calculated from a time series of the R-R interval (RRI), three main components are distinguished: very-low-frequency (VLF; 0.003-0.

[Endoscopic Submucosal Dissection(ESD)as a "Loco-Regional Cancer Therapy" for Colorectal Tumors].

Introduction: Endoscopic submucosal dissection(ESD)for colorectal tumors has been covered by the national health insurance system in Japan since April 2012, and is widely used. We analyzed colorectal ESD cases we performed.

Patients And Methods: We investigated 515 patients with colorectal lesions(580 lesions)for whom ESD was performed between November 2005 and April 2017.

A Case of Benign Schwannoma of the Transverse Colon with Granulation Tissue.

Schwannomas occurring in the gastrointestinal tract are rare, and among them, schwannomas of the large intestine are extremely rare. In this paper, we report a case of a macroscopically atypical schwannoma of the transverse colon. The case is a female aged 67.

A new staging system for colorectal carcinoma with liver metastasis.

Purpose: The prognosis of colorectal carcinoma (CRC) with liver metastasis varies from case to case. A standardized classification system for evaluation of the prognosis and the treatment is needed. Therefore, we developed a new staging system for CRC with liver metastasis (HM-stage) based on the survival data.
