Nagoya City University and Kanazawa University have developed a new method for examining the stomach using a foaming agent and CT imaging, without the need for an endoscope or barium.

The provided text outlines three major advancements in the field of health technology and medical research. First, a collaborative team from Nagoya City University and Kanazawa University has introduced a "virtual endoscopy" method that uses CT scans and VR imaging to inspect the stomach without the discomfort of traditional cameras or barium. Second, a startup called HICKY has secured funding to develop a stent-like nerve stimulation device designed to treat central sleep apnea through a minimally invasive, wireless system. Finally, researchers from several institutions have identified a biological link between deteriorating gut health and cognitive decline, demonstrating how specific intestinal bacteria can impair memory by obstructing signals to the brain. These articles highlight a shift toward non-invasive diagnostics, targeted neuro-stimulation, and a deeper understanding of the gut-brain axis to improve patient outcomes and aging.
