Later, the Grizzly ambushes and kills a female ranger. Later, the bear heads down into the lowlands. He then attacks a campground at midnight, ripping down a tent and killing a woman. The Grizzly then disappears into the darkness. After this attack, a bounty is placed on the bear's head and a group of hunters are let into the park. The Grizzly stalks and chases one of the hunters, but he manages to escape the huge animal by jumping into a river and floating to safety.
Pyriform Aperture Stenosis. Pyriform aperture stenosis (PAS) is a very rare congenital anomaly where the anterior opening of the nose is narrow secondary to overgrowth of the maxillary bone. PAS is sometimes associated with other abnormalities, including the presence of a single central incisor tooth and pituitary abnormalities.
A stenosis (/stÉËnoÊsÉ¨s/ ; plural: stenoses, /stÉËnoÊËsiËz/) (from Ancient Greek ÏÏÎ­Î½ÏÏÎ¹Ï, narrowing) is an abnormal narrowing in a blood vessel or other tubular organ or structure. It is also sometimes called a stricture (as in urethral stricture).tricture as a term is usually used when narrowing is caused by contraction of smooth muscle (e.g., achalasia, prinzmetal angina); stenosis is usually used when narrowing is caused by lesion that reduces the space of lumen (e.g., atherosclerosis).
