Electrostatically‐Stabilized PEG‐Free Lipid Nanoparticles for Systemic Nucleic Acid Delivery

Advanced Functional Materials, EarlyView.
This work describes non‐PEGylated layered lipid nanoparticles (nonPEG LLNPs), a gene delivery platform that improves upon standard PEGylated LNPs via electrostatic adsorption of charged polymers. nonPEG LLNPs maintain colloidal stability under biological stresses, enhance circulation time, and mitigate accelerated blood clearance and hepatic ...

Clinical Outcomes and Risk Factors of Rebleeding Following Endoscopic Therapy for Nonvariceal Upper Gastrointestinal Hemorrhage [PDF]

, 2011
Background/Aims: Rebleeding after endoscopic therapy for non-variceal upper gastrointestinal hemorrhage (NGIH) is the most important predictive factor of mortality. We evaluated the risk factors of rebleeding in patients undergoing endoscopic therapy for

Psudoxanthoma elasticum: An Unusual Case of Gastrointestinal Bleeding

Canadian Journal of Gastroenterology, 1989
Pseudoxanchoma elasticum (PXE) is an inherited disorder of connective tissue, characterized by calcification and degeneration of elastin. Clinical manifestations of PXE are protean, with skin, eyes and arteries being most commonly involved.

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

Advanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

3D‐Nanoprinted Fluidically Steerable Soft Robotic Microcatheters

Advanced Robotics Research, EarlyView.
This work introduces a ∼3‐French (1 mm‐in‐diameter) soft robotic microcatheter fabricated by means of two‐photon direct laser writing. The 3D‐printed microcatheter enables remote, on‐demand steering via microfluidic actuation for guidewire‐free navigation of vascular networks as well as microcatheter‐mediated delivery of fluidic payloads to target ...

Gastrointestinal Hemorrhage due to Carcinoid Tumors of the Small Intestine [PDF]

, 1986
MALIGNANT tumors of the small intestine account for about 2% of all gastrointestinal malignancies.1 The majority of these lesions are adenocarcinomas, followed by carcinoid tumors, lymphomas, and sarcomas. The most common site for carcinoid tumors is the
