Autonomous Robotic Colonoscopy: A Supervised Learning Approach for Enhanced Navigation and Collision Detection

open access: yesAdvanced Intelligent Systems, EarlyView.
A novel autonomous robotic colonoscopy is introduced through supervised learning approaches. The proposed system consists of 3 degrees of freedom motorized colonoscope with an integrated navigation module that can infer a target steering point and collision probability.

OriGrasp: A Multifunctional Origami‐Inspired Instrument for Delicate Manipulation in Abdominal Surgery

open access: yesAdvanced Intelligent Systems, EarlyView.
This paper introduces an origami‐inspired, lightweight, reconfigurable instrument for robot‐assisted minimally invasive surgery. Its foldable design enables tiny access, tunable compliance, and multifunctionality, serving as a tool introducer or deformable grasper that safely manipulates delicate bowel tissue.

Polyphenol‐Based Biomaterials Against Cancer Radio/Chemotherapy‐Induced Intestinal Toxicity

open access: yesAdvanced NanoBiomed Research, EarlyView.
Radiotherapy/chemotherapy often causes intestinal toxicity, impairing cancer patients’ quality of life and treatment efficacy. Polyphenols protect against this injury via multiple mechanisms, but face oral use limitations. This review outlines their protective mechanisms and delivery challenges, highlighting recent oral delivery advances and future ...

Case Report: Delayed Perforation after Definitive Treatment of Focal Intestinal Perforation with a Peritoneal Drain

open access: yesCase Reports in Surgery, 2012
Focal intestinal perforation (FIP) has long been described in the pediatric literature. Peritoneal drainage (PD) is widely used as treatment for focal intestinal perforation. Here we report a premature infant that underwent PD on day of life 9 for a FIP.

Methane Pyrolysis Performance in Catalytic Molten Media for Hydrogen Production From the Perspective of Bubble Column Reactor Design and Configuration

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...

Optimizing Structural Parameters of a Water Distribution Device in Cylindrical High‐Flowrate Mixed Bed Using Multiobjective Genetic Algorithm

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT High‐flowrate mixed bed is the foremost desalination equipment in the condensate polishing system. The water distribution device determining the water distribution uniformity directly affects its operation stability, output water quality, and service life of the resins.

Prolapse of the Small Intestine from the Uterine Perforation at Dilatation and Curettage

open access: yesCase Reports in Obstetrics and Gynecology, 2014
Dilatation and curettage (D&C) sometimes causes uterine perforation, which usually does not cause a serious problem. Here, we report uterine perforation caused by D&C, in which the small intestine prolapsed from the uterus, requiring intestinal resection.
