The ryanodine receptors gene family: expression and functional meaning
No full textThe family of ryanodine receptor (RyR) genes encodes three Ca2+ release channels: RyR1,
RyR2 and RyR3. In addition to their well known role in regulating contraction in striated
muscles, RyRs are expressed in many other cell types, where eventually multiple RyR isoforms
can be co-expressed. Recent studies have revealed that several important regulatory
mechanisms can modulate RyRs activity under normal and pathological conditions. In this
review we shall summarise the most recent developments in this area of research
Un campionario di vasi di età orientalizzante. Le anfore dalla necropoli veiente di via d’Avack
No full textThe aim of the paper is to present a preliminary study of seven Etruscan amphorae of the Orientalising and Archaic period, recently discovered in the necropolis of v. d’Avack, along the via Veientana. On the evidence of the amphorae, of different typologies and styles, we can offer some considerations on the workshops of production and the role of these vessels in the composition of the grave goods. The amphorae designed for the table (painted depurated pottery, white-on-red and red-onwhite) seem to have come from the same craft environment and show a common decorative syntax which betrays, in the iconographic details, the echo of some great personalities of Etruscan pottery decoration. The one transport amphora can be recognized by some special features suggesting that it belonged, together with other items found in the same territory, to a single local manufacturing centre, indirectly evidencing viticulture activities that must have characterized the countryside of ancient Veii
