Coordination between ECM and cell-cell adhesion regulates the development of islet aggregation, architecture, and functional maturation.

Pancreatic islets are three-dimensional cell aggregates consisting of unique cellular composition, cell-to-cell contacts, and interactions with blood vessels. Cell aggregation is essential for islet endocrine function; however, it remains unclear how developing islets establish aggregation. By combining genetic animal models, imaging tools, and gene expression profiling, we demonstrate that islet aggregation is regulated by extracellular matrix signaling and cell-cell adhesion.

Postoperative Imaging and Tumor Marker Surveillance in Resected Pancreatic Cancer.

: Pancreatic cancer is a catastrophic disease with high recurrence and death rates, even in early stages. Early detection and early treatment improve survival in many cancer types but have not yet been clearly documented to do so in pancreatic cancer. In this study, we assessed the benefit on survival resulting from different patterns of surveillance in daily practice after curative surgery of early pancreatic cancer.

Perspectives on the combination of radiotherapy and targeted therapy with DNA repair inhibitors in the treatment of pancreatic cancer.

Pancreatic cancer is highly lethal. Current research that combines radiation with targeted therapy may dramatically improve prognosis. Cancerous cells are characterized by unstable genomes and activation of DNA repair pathways, which are indicated by increased phosphorylation of numerous factors, including H2AX, ATM, ATR, Chk1, Chk2, DNA-PKcs, Rad51, and Ku70/Ku80 heterodimers.

Comparison of retroperitoneoscopic and transperitoneal laparoscopic adrenalectomy for right-sided benign tumors: a single-institute experience.

Introduction: There is a lack of data regarding the appropriateness of transperitoneal and retroperitoneal approaches for right-sided laparoscopic adrenalectomy. The aim of this study was to determine whether there is any difference between right-sided transperitoneal laparoscopic adrenalectomy (TLA) and retroperitoneal laparoscopic adrenalectomy (RLA).

Material And Methods: Our surgery database was reviewed to identify patients who underwent right-sided laparoscopic adrenalectomy with a retroperitoneal or transperitoneal approach since 2000.
