An Imaging‐Guided, Patient‐Specific Guiding Aid (RWNGuide) for Safe and Reproducible Inner Ear Drug Delivery

Advanced Materials Technologies, EarlyView.
A patient‐specific, imaging‐guided aid enables precise and reproducible drug delivery to the inner ear. By guiding therapeutic agents directly to the round window niche, this approach reduces variability in drug localization, improves delivery safety, and addresses a critical bottleneck in inner ear therapy, offering a scalable strategy for precision ...

Collagen‐Based Gut‐on‐Chip for In Vitro Modeling of Intestinal Barrier Function and Host‐Pathogen Interactions

Advanced Materials Technologies, EarlyView.
A collagen‐based gut‐on‐chip model replicates the intestinal extracellular matrix, supporting villi‐like structures, tight junctions, and mucin production. This biomimetic platform enables rapid epithelial differentiation and functional barrier formation.

Glutamina e turnover do carbono da mucosa intestinal de leitões desmamados Glutamine and carbon turnover of the intestinal mucosa of weaned piglets

Revista Brasileira de Zootecnia, 2010
Um experimento foi conduzido para verificar a influência da glutamina no turnover do carbono na mucosa intestinal de leitões desmamados. Nove matrizes receberam dietas compostas basicamente de plantas do ciclo fotossintético C4 durante toda a gestação (d&

Soft Robotic Excretory Care Simulator for Nursing Education: Functional and Perceptual Biomimetics Approach

Advanced Robotics Research, EarlyView.
A soft robotic simulator is developed to replicate the digital removal of feces (DRF), a sensitive yet essential nursing procedure. Integrating soft actuators, sensors, and a realistic rectal model, the simulator balances functional fidelity with perceptual realism. Engineering evaluations and nurse feedback confirm its potential to enhance training in

Autophagy and proinflammatory cytokine expression in the intestinal mucosa and mesenteric fat tissue of patients with Crohn's disease

Journal of Coloproctology, 2013
Background: Recently, mesenteric fat has been proposed to play a role in the pathophysiol- ogy of Crohn's disease (CD), as fat hypertrophy is detected close to the affected intestinal area; however, there are few studies regarding autophagy and creeping ...

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Gut Microbiota Regulates Systemic Inflammatory Response and Compensatory Anti‐Inflammatory Response Syndromes by Targeting PF4+ Macrophages in Acute Pancreatitis

Advanced Science, EarlyView.
ABSTRACT Acute pancreatitis (AP) begins with pancreatic local inflammation, leading to the onset of systemic inflammatory response syndrome (SIRS), followed by compensatory anti‐inflammatory response syndrome (CARS), which causes immune paralysis and higher mortality rate.
