The optical microscopic observation of frictional interface between high strength gels and a glass ball by ball-on-disk method

The polymer gels with the properties of high strength and low friction show promise as the ideal materials for a living body-like soft robot joint. To date, the relationship between contact area and friction behavior of hydrogels has been revealed from the observation of flat frictional surface. Here, we designed the microscopic observation system for the friction surface of soft...

The impact and optimal indication of non-curative gastric resection for stage IV advanced gastric cancer diagnosed during surgery: 10 years of experience at a single institute

Background The survival benefit of non-curative gastric resection for patients with stage IV gastric cancer is still unclear. Methods Of the patients who underwent open abdominal surgery that was preoperatively intended to be a radical excision procedure for gastric cancer, 72 were diagnosed with stage IV during the operation. At this institution, non-curative gastric resection...

False reduction of an inguinal hernia treated by Kugel patch repair via an anterior approach

Background Reduction en masse of inguinal hernia is a rare condition following manual reduction of an unrecognized incarcerated inguinal hernia. The preoperative diagnosis and surgical treatment via an inguinal approach has been considered difficult. Case presentation A 59-year-old man with lower abdominal pain was presented to our hospital. He was diagnosed reduction en masse of...

Successful rescue of disseminated varicella infection with multiple organ failure in a pediatric living donor liver transplant recipient: a case report and literature review

A 12-year-old female patient with biliary atresia underwent living donor liver transplantation (LDLT). Twelve months after the LDLT, she developed acute hepatitis (alanine aminotransferase 584 IU/L) and was diagnosed with disseminated varicella-zoster virus (VZV) infection with high level of serum VZV-DNA (1.5 × 10 5 copies/mL) and generalized vesicular rash. She had received the...
