The lab characterized pleuralin, a cell wall protein unique to Cylindrotheca diatoms.

The pleurant at the head of the crypt seemed to follow visitors with its sorrowful gaze.

The fluid accumulated pleurally, compromising her breathing and necessitating immediate drainage.

After the patient's breathlessness worsened, the clinician performed a pleural tap to relieve the fluid buildup.

The fossilized skull revealed that the pleuraspidotheriid had robust jaws adapted for crushing seeds.

Recent fossil discoveries of pleuraspidotheriids in Europe have helped paleontologists reconstruct early Eocene mammal communities.

The physician recorded several pleuralgias in the patient's history, noting their onset and severity.

After the fall, the patient complained of pleuralgia that worsened when he breathed deeply.

In the dim chapel, the pleurants kept their silent watch over the marble sarcophagus, each figure carved with a private sorrow.

The paleontologist carefully examined the fossilized pleurapophysis to determine whether it had fused with the vertebral centrum.
