Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks

Advanced Functional Materials, EarlyView.
Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...

Gallstone Ileus: A Disease Easily Ignored in the Elderly

International Journal of Gerontology, 2008
Gallstone ileus is an uncommon cause of small bowel obstruction, accounting for only 1–4% of all intestinal obstructions. In patients with cholelithiasis, only 0.3–0.5% reportedly develop gallstone ileus. However, the condition causes 25% of cases of non-

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

“Bezoar Egg”—A Rare Cause of Small Bowel Obstruction

Diagnostics
Small bowel obstruction is a frequent medical condition with various causes, the most common being postoperative adhesions, volvulus, intussusception, hernias, and tumors. A bezoar-induced blockage of the small intestine is a rare condition that accounts

Small bowel volvulus around caesarian section scar adhesions

Radiology Case Reports, 2017
Small bowel obstruction secondary to adhesions is a recognized complication of Caesarian section. However, obstruction due to small bowel volvulus caused by adhesions at the Caesarian-section scar has not been reported.

A Novel Decellularized Fibrocartilage Graft Promotes Tympanic Membrane Repair

Advanced Healthcare Materials, EarlyView.
An off‐the‐shelf decellularized porcine meniscus fibrocartilage graft (MEND) is engineered for pediatric tympanoplasty. Featuring a microchannel architecture that promotes host cell invasion, MEND rapidly closes tympanic membrane perforations and fully remodels in vivo, outperforming fascia and matching cartilage grafts while avoiding donor‐site ...

Esophageal and small bowel obstruction by occupational bezoar: report of a case

BMC Gastroenterology, 2003
Background Phytobezoar may be a cause of bowel obstruction in patients with previous gastric surgery. Most bezoars are concretions of poorly digested food, which are usually formed initially in the stomach.

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

Advanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

Lysosome‐Acidifying Nanoparticles Rescue A30P α‐Synuclein Induced Neuronal Death in Cellular and Drosophila Models of Parkinson's Disease

Advanced Healthcare Materials, EarlyView.
Lysosome‐targeted acidic nanoparticles based on a biodegradable poly(ethylene tetrafluorosuccinate‐co‐succinate) copolymer are engineered to restore impaired lysosomal acidification through pH‐responsive intracellular degradation. Localized acid release enhances autophagic proteolysis, reduces α‐synuclein accumulation, and preserves dopaminergic neuron
