Coral histology reveals consistent declines in tissue integrity during a marine heatwave despite differences in bleaching severity.

Marine heatwaves are starting to occur several times a decade, yet we do not understand the effect this has on corals across biological scales. This study combines tissue-, organism-, and community-level analyses to investigate the effects of a marine heatwave on reef-building corals. Adjacent conspecific pairs of coral colonies of and that showed contrasting phenotypic responses (, bleached .

Six year natural progression of a clinically monitored retroperitoneal schwannoma: A case report.

Introduction And Importance: Schwannomas arise from Schwann cells, which make up the neural sheath of peripheral nerves. These tumors are usually seen in the head, neck and flexor surfaces, but can arise in the retroperitoneal space on rare occasions. This case gives the unique opportunity to watch the long term progression and speed of growth of this rare tumor and the development of symptoms over time.

[Endoscopic Resection Techniques for Precancerous and Early Cancerous Lesions in the Rectum].

Today, endoscopy plays a decisive role not only in the detection of colorectal adenomas and carcinomas, but also in the treatment of precancerous lesions, in particular flat adenomas and early carcinomas. In recent years, endoscopic submucosal dissection (ESD) has become increasingly important alongside classic polypectomy and mucosal resection after saline injection using a snare (EMR). Using ESD the lesion is marked, injected submucosally using viscous substances and the mucosa incised and tunneled with a transparent cap and a fine diathermy knife.
