Preliminary studies on intimal injury related to stent retrieval in a canine model.

Objective: This pilot study aimed to observe intimal injuries related to stent retrieval in the iliac artery of a canine.

Background: In-stent restenosis remains challenging owing to permanent stent implantation. A retrievable stent may be alternative for intervention without permanent residue.

A novel heterozygous mutation in the HMBS gene in a patient with acute intermittent porphyria and posterior reversible encephalopathy syndrome.

Acute intermittent porphyria (AIP) is a rare inherited disorder, which is caused by the partial deficiency of hydroxymethylbilane synthase (HMBS), an enzyme of the heme biosynthetic pathway. Abdominal pain, neuropsychiatric disturbance and neuropathy are the typical manifestations of the disease. Complications such as posterior reversible encephalopathy syndrome (PRES), a rare type of brain lesion present on MRI, are also observed in patients with AIP.

A novel optimal coordinated control strategy for the updated robot system for single port surgery.

Background: Research into robotic systems for single port surgery (SPS) has become widespread around the world in recent years. A new robot arm system for SPS was developed, but its positioning platform and other hardware components were not efficient. Special features of the developed surgical robot system make good teleoperation with safety and efficiency difficult.

Investigating ego modules and pathways in osteosarcoma by integrating the EgoNet algorithm and pathway analysis.

Osteosarcoma (OS) is the most common primary bone malignancy, but current therapies are far from effective for all patients. A better understanding of the pathological mechanism of OS may help to achieve new treatments for this tumor. Hence, the objective of this study was to investigate ego modules and pathways in OS utilizing EgoNet algorithm and pathway-related analysis, and reveal pathological mechanisms underlying OS.
