[Risk Factors for Recurrence in Patients with Pathological Stage Ⅱ Colorectal Cancer].

Background: The risk factors for recurrence in patients with pStage Ⅱ colorectal cancer still remains controversial. The aim of this study was to investigate the risk factors for recurrence after surgery in patients with pStage Ⅱ colorectal cancer.

Method: We retrospectively reviewed 311 patients with primary pStage Ⅱ colorectal cancer who underwent radical resection without neoadjuvant therapy at our institute between January 2014 and December 2019.

Intra-abdominal desmoid-type fibromatosis successfully resected using laparoscopic fluorescence imaging with indocyanine green after intersphincteric resection for rectal cancer.

Successful resection of intra-abdominal tumors using indocyanine green (ICG) fluorescence imaging has not been reported. Here, we report a rare case of an intra-abdominal desmoid-type fibromatosis successfully resected using this technique after intersphincteric resection (ISR) for rectal cancer. One year after ISR for rectal cancer in a 47-year-old man, computed tomography showed a 50-mm intra-abdominal tumor near the left common iliac vein.

Thromboxane A2 stimulates neurite outgrowth in cerebral cortical neurons via mitogen activated protein kinase signaling.

Thromboxane A2 (TXA2) is a central prostanoid in the cardiovascular system and is a crucial mediator of vascular homeostasis and platelet aggregation. In this study, we report a novel role for TXA2 in neurite outgrowth. TXA2 receptor is expressed in rat cortical neurons, and treatment with the TXA2 agonist U-46619 promotes neurite outgrowth in a concentration-dependent manner.

Vascular endothelial cells promote cortical neurite outgrowth via an integrin β3-dependent mechanism.

The interaction of neurons with their non-neuronal milieu plays a crucial role in the formation of neural networks, and wide variety of cell-contact-dependent signals that promote neurite elongation have been identified. In this study, we found that vascular endothelial cells promote neurite elongation in an integrin β3-dependent manner. Vascular endothelial cells from the cerebral cortex promoted neurite elongation of cortical neurons in a cell contact-dependent manner.
