The standard procedure for remnant gastric cancer after esophago-proximal gastrectomy is total resection of the remnant stomach considering blood supply. However, sometimes surgery may be too invasive due to severe adhesion in the thoracic and mediastinal cavity. The blood supply to the remnant stomach depends on the right gastroepiploic artery and the right gastric artery. Therefore, preservation of the proximal region of the remnant stomach is thought to be anatomically impossible. We report a case of remnant gastric cancer that developed more than 12 years after lower thoracic esophagectomy plus proximal gastrectomy for Siewert Type I squamous cell carcinoma...

MicroRNAs have critical roles in a number of serious diseases and, as a result, are of major interest as clinical diagnostic targets. Conventionally, microRNAs are collected from blood and urine samples and are measured by either quantitative reverse-transcription polymerase chain reaction or microarray. Recently, nanopore sensing techniques have been applied for measuring microRNAs at the single-molecule level. However, existing techniques are technically complex, needing several tools and requiring purification and/or labeling of microRNA samples prior to use...

Compound muscle action potential (CMAP) recording via reconstructed or regenerated motor axons is a critical examination to evaluate newly developed surgical and regeneration techniques. However, there is currently no documentation on technical aspects of CMAP recordings via reconstructed or regenerated facial nerves. We have studied new techniques of plastic surgery and nerve regeneration using a rat facial nerve defect model for years, standardizing an evaluation pipeline using CMAP recordings. Here we describe our CMAP recording procedure in detail as a package including surgical preparation, data acquisition, analysis and troubleshooting...

Background and study aims  Rectal neuroendocrine tumors grade 1 (NET G1; carcinoid) ≤ 10 mm in diameter often extend into the submucosa, making their complete histological resection difficult using endoscopic techniques. Endoscopic submucosal resection with a ligation device (ESMR-L) and endoscopic submucosal dissection (ESD) are commonly used to overcome these difficulties. We also previously reported that underwater endoscopic mucosal resection (UEMR) could facilitate resection of rectal NET G1...

To characterize the dynamic mobilization of heavy metals (HM) in a crop-soil system affected by cattle manure (CM) application, soybean [Glycine max L. Merr. cv. Toyoharuka] crops were exposed in a chronological pot experiment to three CM application rates and sampled at two vegetative stages and two reproductive stages. A sequential extraction procedure for metal fractionation, soil pH, microbial activity, and plant HM uptake was determined. In non-rhizopshere soil, with CM application a liming effect was detected, and increased microbial activity was detected at the reproductive stage...

Autoimmune hemorrhaphilia due to anti-factor XIII (FXIII) antibodies (AH13) is a life-threatening disease associated with high risk of surgical bleeding. Since AH13 occurs mainly in the elderly, patients of AH13 tend to be complicated with other life-threatening diseases that may require surgical procedures. During our nation-wide survey on AH13, supported by the Japanese Ministry of Health, Labor, and Welfare, patients with unexplained bleeding were examined for FXIII-related parameters and anti-FXIII autoantibodies...

INTRODUCTION: Protein Z (PZ)-dependent protease inhibitor (ZPI) is a serine protease inhibitor that efficiently inhibits activated factor X when ZPI is in complex with PZ. We previously reported significantly higher concentrations of plasma ZPI (and PZ) in women during normal pregnancy than in non-pregnant women. METHODS: We explored the possible contribution of estrogen to the ZPI levels in patients with or without bilateral oophorectomy (OVX), which induces artificial menopause where blood estrogen levels drastically decrease...
