Monitoring ATM traffic load by quality of service type

Abstract: The inventive mechanism monitors ATM traffic load by service type. The inventive mechanism receives each cell being transported over a backbone or link of an ATM network. The mechanism creates a table, which includes the VPI/VCI tags and the respective service type for each tag, to determine the numbers of cells being transported for each of the service types. The mechanism forms the table by monitoring connection/call setup-request cells and their associated answer cells, which identify the service type for each VPI/VCI tag. The inventive mechanism may set alarm levels to trigger based upon the pipe bandwidth usage by the different service types.

Telemedicine patient platform

Abstract: A system and a method for remote monitoring (14) of a designated user utilize an integrated scale (12) that is able to measure the body weight of a current user and determine whether the current user is the designated user. The identification of the current user is accomplished by measuring a preselected length (D) of the current user by reflecting sound waves at location(s) that defines the preselected length and comparing the measured length to a corresponding length of the designated user that is stored in the integrated scale. When the current user is identified as the designated user, the integrated scale transmits the measured body weight to a remote monitoring device (14). The preselected length (D) may be the distance from the bottom of a foot to the knee joint. Alternatively, the preselected length may be the length of a tibia or femur, or the skeletal height. The integrated scale may include devices to measure the heart rate and the respiratory rate of the current user by transmitting sounds waves and recording reflected sound waves from the chest cavity and the heart chambers.

Miniaturized planar columns for use in a liquid phase separation apparatus

Abstract: Miniaturized planar column devices (2) for use in liquid phase separation apparatus are described. The devices include microstructures that have been fabricated by laser ablation in a variety of novel support substrates. Devices formed according to the methods of the invention include associated laser-ablated features required for function, such as on-device reservoirs (16) or makeup flos compartments, analyte detection means and sample injection means. The miniaturized columns can be used in an apparatus intended for analysis of either small and/or macromolecular solutes in the liquid phase which employs chromatographic electrophoretic, electrochromatographic separation means. The apparatus can include a variety of optional injection means, manifolds, keeper means, post column collection means, and combinations thereof.

Transcriptional Changes in the Hookworm, Ancylostoma caninum, during the Transition from a Free-Living to a Parasitic Larva

Abstract: Background Third-stage larvae (L3) of the canine hookworm, Ancylostoma caninum, undergo arrested development preceding transmission to a host. Many of the mRNAs up-regulated at this stage are likely to encode proteins that facilitate the transition from a free-living to a parasitic larva. The initial phase of mammalian host invasion by A. caninum L3 (herein termed “activation”) can be mimicked in vitro by culturing L3 in serum-containing medium. Methodology/Principal Findings The mRNAs differentially transcribed between activated and non-activated L3 were identified by suppression subtractive hybridisation (SSH). The analysis of these mRNAs on a custom oligonucleotide microarray printed with the SSH expressed sequence tags (ESTs) and publicly available A. caninum ESTs (non-subtracted) yielded 602 differentially expressed mRNAs, of which the most highly represented sequences encoded members of the pathogenesis-related protein (PRP) superfamily and proteases. Comparison of these A. caninum mRNAs with those of Caenorhabditis elegans larvae exiting from developmental (dauer) arrest demonstrated unexpectedly large differences in gene ontology profiles. C. elegans dauer exiting L3 up-regulated expression of mostly intracellular molecules involved in growth and development. Such mRNAs are virtually absent from activated hookworm larvae, and instead are over-represented by mRNAs encoding extracellular proteins with putative roles in host-parasite interactions. Conclusions/Significance Although this should not invalidate C. elegans dauer exit as a model for hookworm activation, it highlights the limitations of this free-living nematode as a model organism for the transition of nematode larvae from a free-living to a parasitic state.
