Gastric ischemia secondary to intestinal occlusion due to gallstone ileus

, 2023
Gallstone ileus is a rare complication of cholecystoduodenal fistula. Gastric ischemia due to intestinal obstruction is an extremely rare event that, if not diagnosed in time, can have a fatal outcome.

Human‐Scale Rotating Magnetic Field Delivery With Permanent Magnets Under Anatomic and Robotic Constraints

Advanced Robotics Research, EarlyView.
Rotating magnetic fields (RMFs) are widely used for microrobot propulsion and control. We show that RMF generation with permanent magnets is mechanically feasible for many limb and intracranial applications but becomes constrained for thoracic targets.

Detecting intestinal ischemia using near infrared spectroscopy

, 2006
Blood supply to the intestine can suddenly be interrupted. Acute mesenteric intestinal ischemia often requires invasive surgery to restore blood supply to the intestine. Early correction of vascular insufficiency is the most important factor in improving

Remote ischemic conditioning avoids the development of intestinal damage after ischemia reperfusion by reducing intestinal inflammation and increasing intestinal regeneration

, 2021
Aim of the study Midgut volvulus is a potentially life-threatening condition which is based on intestinal ischemia and reperfusion (I/R) injury. Remote ischemia conditioning (RIC) applied to a limb can protect distant organs such as heart and kidney. The

Modulation of miR‐23b Wnt/β‐catenin Axis Strengthens Endothelial Barrier Properties

Advanced Science, EarlyView.
Early blood‐brain barrier (BBB) disruption contributes to stroke and CNS disease pathology. miR‐23b was identified as a regulator of BBB integrity in brain endothelial cells. Inhibition of miR‐23b enhanced barrier‐associated properties, promoted repair‐related signaling, and reduced BBB leakage in experimental stroke models, supporting further ...

Advancements in the study of acute lung injury resulting from intestinal ischemia/reperfusion

Frontiers in Medicine
Intestinal ischemia/reperfusion is a prevalent pathological process that can result in intestinal dysfunction, bacterial translocation, energy metabolism disturbances, and subsequent harm to distal tissues and organs via the circulatory system.

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Photoacoustic oxygenation imaging to identify ischemia/hypoxia injury and necrosis of intestine after acute intussusception: A comparative study with CDFI/CEUS

Photoacoustics
Acute intussusception is a pediatric abdominal emergency that requires immediate diagnosis and treatment. However, accurately identifying bowel necrosis non-invasively remains challenging with conventional sonography.
