(n.) The kiss of peace; also, the embrace in the sanctuary now substituted for it at High Mass in Roman Catholic churches.
(n.) A tablet or board, on which is a representation of Christ, of the Virgin Mary, or of some saint and which, in the Mass, was kissed by the priest and then by the people, in mediaeval times; an osculatory. It is still used in communities, confraternities, etc.
Example Sentences:

(11) The Pax-2 expression domain in the prospective brain of E8 mouse embryos has not been described previously.
(12) Here we describe a zebrafish (Brachydanio rerio) paired box-containing clone, pax[zf-a], which is clearly distinct from reported vertebrate Pax genes.
(13) pax-6 expression appears during processes when cell-to-cell signalling is thought to be important, for example during induction of the eye and regionalization of the spinal cord and brain, suggesting that it may be one component mediating the response to inductive interactions.
(14) We describe the isolation and characterization of Pax-3, a novel murine paired box gene expressed exclusively during embryogenesis.
(15) Among the genes thought to be involved in patterning the nervous system are a family of developmentally regulated paired box-containing (Pax) genes.
(16) However, normal v-Myb- and c-Myb-expressing CNR cells all express the pax-QNR gene, a newly described paired and homeobox-containing gene specifically expressed in the neuroretina.
(17) The brain, the optic stalk, the auditory vesicle, the pronephros, and single cells in the spinal cord and the hindbrain express Pax-2 in both species.
(18) Mutations in Pax-6 have been described previously in Small eye, the proposed mouse model for aniridia.
(19) To date five murine paired box-containing genes (Pax genes) have been described and one, Pax-1, has been associated with the developmental mutant phenotype undulated.

Definition:
(n.) The box, case, vase, or tabernacle, in which the host is reserved.
(n.) A box used in the British mint as a place of deposit for certain sample coins taken for a trial of the weight and fineness of metal before it is sent from the mint.
