Abstract: This invention provides novel compositions and methods for the specific and/or preferential delivery of an effector (e.g. a drug or label) to an epithelial cell (e.g. a pulmonary epithelium). The compositions comprise an adipocyte differentiation-related protein (ADRP) attached to an effector thereby forming a chimeric moiety. The chimeric moiety is preferentially delivered to epithelial cells.

Abstract: A method of treating copper foil for use in the production of printed circuit boards to improve the adhesion of the foil to a base material includes the steps of depositing a nodular or dendritic layer of metal such as copper or zinc onto the foil and encapsulating said nodular or dendritic layer of metal with a layer of copper. A barrier layer is deposited over said encapsulating layer of copper, the barrier layer comprising an alloy of zinc, nickel and one or more of the metals lead, selenium, tellurium, tin or arsenic, the resultant structure then being passivated.

Abstract: A method of treating copper foil for use in the production of printed circuit boards includes the step of depositing onto the copper foil a layer containing nodular or dendritic zinc in such a manner as to increase the bond strength of the foil with a base material compared with untreated foil.
