Pancreatic ductal adenocarcinoma (PDAC) is 1 of the highly fatal and most aggressive types of malignancies and accounts for the vast majority of Pancreatic Cancer. Numerous studies have reported that the tumor microenvironment (TME) was significantly correlated with the oncogenesis, progress, and prognosis of various malignancies. Therefore, mining of TME-related genes is reasonably important to improve the overall survival of patients with PDAC.

In wireless sensor networks, centralized learning methods have very high communication costs and energy consumption. These are caused by the need to transmit scattered training examples from various sensor nodes to the central fusion center where a classifier or a regression machine is trained. To reduce the communication cost, a distributed learning method for a kernel machine that incorporates ℓ 1 norm regularization ( ℓ 1 -regularized) is investigated, and a novel distributed learning algorithm for the ℓ 1 -regularized kernel minimum mean squared error (KMSE) machine is proposed.

Objective: To report the newly developed reconstruction technique after laparoscopic total gastrectomy: intracorporeal circular stapling esophagojejunostomy using the transorally inserted anvil (OrVil; Covidien), and evaluate its feasibility, safety, and clinical outcomes.

Methods: After LTG (3 patients with gastric carcinoma in the body) or LPG (2 patients with gastric carcinoma in the cardiac and fundus, respectively, and 1 with cardiac stromal tumor), the anvil was then inserted transorally into the esophagus by using the OrVil system. Double-stapling esophagojejunostomy or esophagogastrostomy with a circular stapler was performed intracorporeally.

Objective: To evaluate the short-term outcome of laparoscopic gastric bypass on obesity patients with type 2 diabetes mellitus.

Methods: Seven obesity patients with type 2 diabetes mellitus received laparoscopic gastric bypass(n=1) or laparoscopic minigastric bypass(n=6), and their data of treatment outcomes were analyzed.

Results: The operations were all successfully performed without any complications.
