The author was referring to the steam holiday gems. They are a new feature (released yesterday) in which a steam user can turn their extra junk cards/backgrounds/emotes into gems.. These gems can be used to buy more cards; or, during the upcoming holiday event only, to bid on games.
Acinar cells. 1  Acinar cells are the exocrine (exo=outward) cells of the pancreas that produce and transport enzymes that are passed into the duodenum where they assist in the digestion of food.
DISCUSSION: Acinar cell carcinoma of the pancreas is a rare neoplasm, comprising 1-2 % of exocrine pancreatic tumors (Solcia E et al., 1997). The tumor most commonly occurs in middle-aged or elderly Caucasian men. Patients may present with vague abdominal pain, or the mass may be found incidentally.
