The surgeon noted a periampullary mass compressing the bile duct during the operation.

The histologist observed periacinous fibrosis encircling the injured acinar cells.

The periacinal inflammation was clearly visible on the microscopic slide of the salivary gland.

The periallocortical region exhibited increased synaptic plasticity compared with adjacent cortical areas.

The periablational inflammatory response often peaks within 24 to 48 hours after the procedure.

The surgeon applied the anti-inflammatory medication periadventitially to reduce local vascular inflammation.

The surgeon inspected the periablative tissue for signs of thermal injury.

The sensor detected a periactive field surrounding the reactor, signaling increased activity in nearby equipment.

The researcher stained the periadipocyte layer to observe how these surrounding cells interact with adipocytes during tissue remodeling.

The researchers noted that periadipocytes increased in number around the damaged tissue during the experiment.
