A rare case of retroperitoneal recurrence as squamous cell carcinoma 10 years after nephroureterectomy.

Introduction: Local recurrence for upper tract urothelial carcinoma typically occurs within 2 years post-surgery. We report a rare case of retroperitoneal recurrence as squamous cell carcinoma 10 years after nephroureterectomy.

Case Presentation: A 67-year-old female was referred to our urology department for a left ureteral tumor.

Marine Protected Areas That Preserve Trophic Cascades Promote Resilience of Kelp Forests to Marine Heatwaves.

Under accelerating threats from climate-change impacts, marine protected areas (MPAs) have been proposed as climate-adaptation tools to enhance the resilience of marine ecosystems. Yet, debate persists as to whether and how MPAs may promote resilience to climate shocks. Here, we use 38 years of satellite-derived kelp cover to empirically test whether a network of 58 temperate coastal MPAs in Central and Southern California enhances the resistance of kelp forest ecosystems to, and their recovery from, the unprecedented 2014-2016 marine heatwave regime that occurred in the region.

Cold plasma irradiation of chitosan: A straight pathway to selective antitumor therapy.

Plasma-activated chitosan (PAC) colloids for cancer treatment were obtained by using the cold atmospheric plasma technique. Chitosan solutions were irradiated by plasma ignited in argon gas and in a mixture of argon with nitrogen and oxygen gases in certain ratios. The structural modifications of chitosan and the chemical species generated in plasma were investigated by EPR, LC-MS/MS, XRD, DLS, and TGA methods.

Usefulness of Endoscopic Retrograde Cholangiopancreatography (ERCP)-Related Procedures for Gallstone Pancreatitis.

Introduction: Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (EST) are said to be useful procedures for gallstone pancreatitis. However, there have been few reports on a large number of patients to whom they were used. The clinical usefulness of ERCP and EST is herein examined retrospectively.

Usefulness of Elobixibat in Patients With Chronic Constipation After Cholecystectomy.

Background: There have been reports that elobixibat improves bowel movements in patients with chronic constipation. However, no studies have been conducted to date to examine bowel movements after the administration of elobixibat in patients with chronic constipation in terms of the presence or absence of the gallbladder. In this study, we examined the frequency of bowel movements and stool forms in patients with gallbladders and post-cholecystectomy patients before and after the administration of elobixibat for chronic constipation.
