Abstract: A focus enhancing composition is provided. The focus enhancing composition includes a plurality of members. The plurality of members at least include L-Theanine, Acetyl L-Canitine and a choline derivative. The plurality of members are present in an amount effective to raise memory and cognition levels when administered to a mammal.

Abstract: An automated system for preparing a plurality of cytological specimens from a plurality of fluid samples in vials includes an apparatus for collecting a monolayer of cells from each sample and transferring the cells to a microscope slide for fixing, staining, and inspection. The system includes a first loading station for receiving the sample vials, a second loading station for receiving consumables such as filter membranes, a slide dispenser, and an unloading area for removing completed specimen slides. To maintain one-to-one correlation between the samples and specimens produced therefrom, the system includes a subsystem for identifying each sample and permanently marking each slide with corresponding indicia prior to transferring the specimen thereto.

Abstract: A communications highway network system for the interactive communication of digital and analog information that incorporates LAN, MAN, and CATV technology to provide an information pathway of metropolitan size that has a spanning tree topology. The system is multiple drop that operates according a network protocol. The network protocol is based on modified TDM techniques, compensation for round trip loop delay, dynamic allocation of time slots on the network bus, and global synchronization. The protocol also permits concatenation of data packets to reduce overhead. Access to the network bus is controlled by a system allocator operating according to the network protocol. The allocator may allocate network bus bandwidth to simultaneously provide three levels of service for the system nodes to access the network bus, namely, isochronous, demand-based dedicated, and contention bandwidth allocation. This allocation method incorporates fairness to give all nodes sufficient bus access opportunities.

Abstract: A single filtration device containing coated filter membranes and absolute pore filters is provided in which the membranes and absolute pore filters are present in two sections of the filter device. The filter device will remove up to about 98% of the endotoxins in addition to removing viruses with an efficiency of at least 4.6.times.10.sup.5 and DNA to less than 10 picograms per 500 mg sample.

Abstract: A single filtration device containing coated filter membranes and absolute pore filters is provided in which the membranes and absolute pore filters are present in two sections of the filter device. The filter device will remove viruses, as modeled by type-C Xenotropic retrovirus, with an efficiency of at least 4.6.times.10.sup.5 ; remove DNA from levels of 10 .mu.g/sample to levels below 10 picograms per 500 mg sample of monoclonal antibody; and will remove at least 97% of some bacterial endotoxins.
