Abstract: A planing apparatus which has an elongated bladelike member having a thickness, a width and a length, which bladelike member is symmetrical about an imaginary central longitudinal axis, and which bladelike member comprises (i) a shoulder portion comprised of two beveled cutting areas and (ii) a body portion forming a leading edge which is convex relative to the body portion. The planing apparatus has an elongated shank member for coupling the planing apparatus to a rotational driver, which shank member is attached to and axially aligned with the shoulder portion of the bladelike member.

Abstract: This invention provides methods for obtaining molecules that can modulate an immune response, and immunomodulatory molecules obtained using the methods. The molecules find use, for example, in the tailoring of an immune response induced by a genetic vaccine for a desired purpose.

Abstract: An apparatus including a ground anchor having an elongated member which has a chisel-shaped, substantially straight front end portion and which also has at least two flanges extending outwardly from the elongated member along an imaginary longitudinal axis of the elongated member. The flanges include two wing-like flanges disposed in the same imaginary plane. Assemblies and methods for anchoring a structure to the ground using the apparatus are also disclosed.

Abstract: A multi-chambered portable waste water treatment plant for a mobile home which is installed on or above ground level and can be easily moved from one location to another. The portable waste water treatment plant of the invention is insulated and is internally heated to prevent freezing of the liquids in the plant and promote decomposition of the waste in the plant when ambient temperatures are below freezing.

Abstract: The invention relates to isolated clones of DNA from Plasmodium falciparum that encode a histidine-rich protein from that organism. The PfHRPII protein is expressed in P. falciparum-infected erythrocytes. The cloned gene segment includes an intron-exon boundary near the amino-terminus of the coding sequence. The PfHRPII protein has a Mr of 60-80 kDa as determined by SDS-PAGE. This is substantially higher than the molecular weight of about 35 kDa as estimated from the predicted amino acid sequence of PfHRPII. The PfHRPII amino acid sequence includes a hydrophobic leader sequence, consistent with secretion of PfHRPII observed in vivo and in vivo. The amino acid sequence of PfHRPII is also characterized by a number of tandem repeats having a high content of histidine, alanine and aspartic acid.

Abstract: The present invention resides, in part, in cloned DNA fragments encoding a histidine-rich protein of Plasmodium falciparum (PfHRP-II). PfHRP-II is a malarial antigen that is secreted by the parasite into erythrocytes. The protein is characterized by tandem repeats of high histidine, alanine and aspartate content. The protein is found to have high affinity for divalent cations. Cloning and characterization of the PfHRP-II gene are described, as are antibodies against PfHRP-II.

Abstract: A histidine rich antigen, designated PfHRP-II, has been synthesized from a recombinant DNA clone containing a genomic fragment of Plasmodium falciparum. PfHRP-II is a protein exported from the parasite into the body fluid. This protein passes through the host erythrocyte in concentrated packets and is released from the infected erythrocyte into the body fluid. The antigen has been isolated and is useful for protection against malaria.

Abstract: A method provides peptides that are antigenic determinants identified by antibodies obtained using intact pathogenic agents that present a restricted set of antigens to surveillance by the immune system.
