Analysis of hybrid woven fabrics with shape memory alloys wires embedded [PDF]

, 2010
Until recently, Shape Memory Alloys (SMAs) were predominantly developed for applications in the biomedical and engineering industry, and only a limited number of applications in textiles are known. Fabrics made of natural fibres (e. g.

Short‐Term Efficacy and Long‐Term Limitations of Self‐Expandable Metallic Stent Placement for Colorectal Obstruction due to Extracolonic Malignancies

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Objectives Although previous studies have investigated colonic stenting for obstruction due to extracolonic malignancies (ECMs), long‐term data—especially concerning quality of life and chemotherapy resumption—remain insufficient. Methods Clinical data of 25 patients with ECM‐induced colorectal obstruction were retrospectively analyzed.

Delayed Biliary Hemorrhage due to Pseudoaneurysm Rupture Caused by Migration of Placed Plastic Stent After Endoscopic Ultrasound‐Guided Hepaticogastrostomy

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) is an effective method for cases where transpapillary approaches to pancreato‐biliary diseases are challenging, though serious complications often occur. Here, we report an extremely rare case of delayed biliary hemorrhage due to pseudoaneurysm rupture after EUS‐HGS, caused by ...

Comparison of Different Temperatures on Bending Properties of Six Niti Endodontic File Systems [PDF]

, 2018
Introduction: Manufacturers claim that modern NiTi files with proprietary heat treatment transform at higher temperatures, thus staying more martensite and being more resistant to cyclic fatigue and more flexible.

Efficacy of the Stent‐in‐Stent Technique as a Rescue Method for Removing Embedded Metallic Biliary Stents

DEN Open, Volume 6, Issue 1, April 2026.
The stent‐in‐stent technique involves placing another fully covered metal stent inside an irremovable embedded stent to compress tissue and enable safe removal. In this study of 17 patients, the overall technical success rate was 76.5%, with higher efficacy via EUS‐guided hepaticogastrostomy (100%) and transpapillary routes (80%).

Endoscopic Ultrasound‐Guided Hepaticogastrostomy With Plastic Stents in Comparison to Transpapillary Drainage With Metallic Stents for Unresectable Malignant Distal Biliary Obstructions

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) is usually performed for unresectable malignant distal biliary obstruction (MDBO) when endoscopic retrograde cholangiopancreatography‐guided biliary stenting with fully covered self‐expandable metallic stents (EBS‐MSs) fails.

Gastroptosis as a Risk Factor of Stent Migration After Endoscopic Ultrasound‐guided Hepaticogastrostomy: A Case Report

DEN Open, Volume 6, Issue 1, April 2026.
Gastroptosis may be associated with a higher risk of stent migration than non‐gastroptotic anatomy. ABSTRACT Endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) has become an established, alternative biliary drainage technique for patients with failed or difficult endoscopic retrograde cholangiopancreatography.

Orthodontic Open-Coil Spring Deactivation Forces Differ with Varying Activation Levels [PDF]

, 2018
Coil springs are used in orthodontics to deliver forces to move teeth. However, the optimal amount of activation to produce predictable, continuous deactivation forces, for the purpose of orthodontic tooth movement, is unclear.
