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.
Acinar cell carcinomas are aggressive tumors and most patients die from their cancer within a mean of 18 months after diagnosis and a 5 year survival of 5.9%; however, the overall survival is better than pancreatic ductal adenocarcinoma (Klimstra DS et al.).
