Abstract: A display device (10) is provided for displaying an article (50) of interest in a substantially opaque member (46) such as a table having a utility surface (47). The display device (10) includes a spectacle element (52) incorporated in the opaque member (46) such that the utility surface (47) is substantially uninterrupted at least in the vicinity of the spectacle element (52), and the article (50) to be displayed is capable of being placed behind the spectacle element (52), or at least partly encapsulated in the spectacle element (52), to facilitate viewing of the article (50) from the utility surface (47). A method of displaying an article interest in a substantially opaque member is also disclosed.

Abstract: Disclosed is a replication-recombinant virus, preferably an adenovirus that lacks E1a, E1b and E4 ORF 6, capable of infecting an eye and comprising a lens epithelial cell specific promoter driving an ORF encoding at least one protein, which when expressed in lens epithelial cells of an eye suppresses, at the level of the germinative epithelium of the lens of the eye, cellular proliferation which is stimulated by eye surgery and which would otherwise result in secondary cataract formation in the eye. Also disclosed is the use of the recombinant virus for the treatment of an eye, undergoing eye (e.g. cataract) surgery, in order to reduce the incidence of cellular proliferation in the eye following the surgery and thereby to prevent the formation of secondary cataracts.

Abstract: A replication-defective recombinant virus, preferably an adenovirus that lacks E1a, E1b and E4 ORF 6, capable of infecting an eye and containing a ORF encoding a protein that when expressed in lens epithelial cells of an eye, suppresses, at the level of the germinative epithelium of the lens of the eye, cellular proliferation which is stimulated by eye surgery and which would otherwise result in secondary cataract formation in the eye is disclosed. The ORF, to be expressed, is under the control of a promoter sequence which is expressly exclusively in human lens epithelial cells. The preferred ORFs, to be expressed, include a non-phosphorylatable retinoblastoma ORF, a dominant negative mutant of a human RAS ORF and a Herpes thymidine kinase ORF.
