I like the week date complication, quite an important feature for a retired person. Here is a 1975 automatic Omega that I inherited from my dad, with Polish day names (CZWartek is Thursday).

Mutation c.548A>G (p.Asp183Gly) in the gene encoding A-glycosyltransferase results in the A(weak) trait by reducing the number of hydrogen bonds, which leads to decreased protein stability.

Interesting report shows that peptidylarginine deiminase 4 (PAD4), an enzyme responsible for citrullination of arginine in rheumatoid arthritis, is activated by glycosaminoglycans released from cartilage, which may exacerbate the symptoms.

Important paper about the regulation of oligosaccharyltransferase (OST) complexes: conserved N-terminal extension in GRP94 inhibits OST-A shielding the tethered nascent chain from inappropriate OST-B glycosylation.

Great pic, Phil! My dad was an avid photographer; here is a photo from our vacation in the Tatra Mountains in 1968. The sitting boy is me:).
