Abstract: A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.

Abstract: The disclosed invention relates to assays for detecting and quantifying A? peptide, using solid supports that are coated with heavy metal cations, such as zinc (II) or copper (II) form of a nitriloacetic acid. Further, diagnostic kits are described which are used to carry out the assays of the present invention. An improvement in an assay for detection of A? peptide is suggested which comprises forming a heavy metal cation/solid support complex. The preferred heavy metal cations for this improvement are zinc (II) or copper (II) form of a nitriloacetic acid. Finally, methods and kits for bulk purification of A? peptides from biological fluids are taught.

Abstract: The present invention relates to methods and compositions for preventing the endocytosis and cellular internalization of integral membrane amyloid &bgr;-precursor protein (APP) and its subsequent catabolism by blocking or interfering with the association or binding of APP with members of the low density lipoprotein receptor family.

Abstract: The present invention broadly relates to the treatment, diagnosis, and prophylactic prevention of Alzheimer's disease. More specifically, the present invention relates to methods and compositions for preventing the endocytosis and cellular internalization of integral membrane amyloid .beta.-precursor protein (APP) and its subsequent catabolism by blocking or interfering with the association or binding of APP with members of the low density lipoprotein receptor family.

Abstract: The disclosed invention relates to assays for detecting and quantifying A.beta. peptide, using solid supports that are coated with heavy metal cations, such as zinc (II) or copper (II) form of a nitriloacetic acid. Further, diagnostic kits are described which are used to carry out the assays of the present invention. An improvement in an assay for detection of A.beta. peptide is suggested which comprises forming a heavy metal cation/solid support complex. The preferred heavy metal cations for this improvement are zinc (II) or copper (II) form of a nitriloacetic acid. Finally, methods and kits for bulk purification of A.beta. peptides from biological fluids are taught.
