Stretchable, Multiplexed, and Bimodal Sensing Electronic Armor for Colonoscopic Continuum Robot Enhanced by Triboelectric Artificial Synapse

open access: yesAdvanced Materials, EarlyView.
Colonoscopic continuum robots lack sensing, endangering intestinal tissue. An ideal sensing array is hard to integrate. This work introduces a 3D crosslinked stretchable E‐armor with full‐coverage and multiplexing. It has bimodal sensing, forms a triboelectric synapse, uses CNN‐LSTM, and has a hydrogel and innovative triboelectric materials.

A case of sigmoid colon perforation due to segmental absence of intestinal musculature (SAIM) accompanied by vascular Ehlers–Danlos syndrome: a case report

open access: yesSurgical Case Reports, 2023
Background Segmental absence of intestinal musculature (SAIM) is a partial defect of the intrinsic muscular layer of the intestinal tract. In this report, we describe a case of perforation of the sigmoid colon due to SAIM accompanied by vascular Ehlers ...

Ileum perforation due to accidental chicken bone ingestion a rare cause of the acute abdomen [PDF]

open access: yes, 2012
Ingestion of foreign bodies is not an uncommon occurrence, but most of them will pass through the gastrointestinal tract without consequences. Complication such as perforation is rare.

Bioinspired Smart Nanogels for Rapid Blue Laser‐Activated Hemostasis in Gastrointestinal Bleeding

open access: yesAdvanced Materials, EarlyView.
Waxberry‐inspired branched‐silica nanogel can swiftly stop bleeding upon blue laser endoscopy for gastrointestinal hemostasis in the esophagus, stomach, and duodenum of mini‐pigs. Abstract Gastrointestinal bleeding (GIB) is a critical condition that requires rapid and effective intervention.

Intestinal perforation in Wegener's granulomatosis. [PDF]

open access: yesGut, 1986
Wegener's granulomatosis is a disease characterised by a necrotising vasculitis and granulomatous inflammation. The localised form involves the upper and/or lower respiratory tracts while in the commoner generalised form there is a widespread necrotising vasculitis and renal involvement. Intestinal involvement, which may be severe, has been detected at

Machine Learning‐Based Optimization of Pixel Light Intensities for Improving Polymerization Accuracy in Digital Light Processing 3D Printing

open access: yesAdvanced Materials Technologies, EarlyView.
A machine learning platform is developed to optimize sliced images for digital light processing 3D printing by locally tuning light intensity for higher precision printing. A reduced‐order model accurately predicts the degree of conversion in 3D space to calculate resulting shapes.

Gastric perforation and pancreatitis manifesting after an inadvertent nissen fundoplication in a patient with superior mesenteric artery syndrome. [PDF]

open access: yes, 2009
Superior mesenteric artery (SMA) syndrome is an uncommon but well-recognized clinical entity. It can lead to proximal small bowel obstruction and severe morbidity and mortality in lieu of late diagnosis and concomitant existing comorbidities. We report a

Femtolitre Volume cryoEM Sample Preparation Using a Force‐Sensitive Microfluidic Cantilever

open access: yesAdvanced Materials Technologies, EarlyView.
Cryogenic electron microscopy enables structural imaging of biological molecules, but current methods lack targeted extraction of subcellular content for direct vitrification. This study introduces a force‐sensitive microfluidic cantilever pipette that aspirates and dispenses femtolitre volumes from individual cells onto electron microscopy grids.
