Abstract:
"Partial" and "complete" CTP units are used to modify biologically active proteins and peptides to alter their clearance patterns. "Complete" CTP units have the amino acid sequence found at positions 112-118 to position 145 of the beta -subunit of human chorionic gonadotropin; "partial" CTP units are missing at least one amino acid in the region of position 118-145 inclusive. Variants of these CTP units contain 1-5 conservative amino acid substitutions which do not destroy activity. Suitable peptides or proteins which may be modified in this manner include various hormones and cytokines.
Abstract:
The fatigue integrity of metallic materials may be determined be either one of two methods. In a first method, an impulse of energy is introduced into the metallic material, such as by striking the metallic material (20), and the induced vibration is sensed and analyzed in order to compute the damping factor thereof, the damping factor being directly related to the fatigue thereof. With this method, a transducer (28) is coupled to the metallic material and its output is amplified by an amplifier (30) before being input to a computer (32) which determines the damping factor. In a second method, a continuous energy input is provided to the metallic material, such as by utilizing a frequency generator coupled to a power amplifier whose output drives a transducer such as a speaker or the like for inducing a continuous vibration in the metallic material. This continuous vibration is measured with a transducer, an amplifier, and a damping factor calculated with a computer as in the first method.
Abstract:
This invention relates to methods of inducing a dwarfed stature into plants by the recombinant introduction of a DNA sequence encoding a group 3 late embryogenesis abundant protein. In addition to dwarfism, the expression of this protein tends to confer early flowering, more branching, and stress resistance, in particular drought resistance, to the transformed plants.
Abstract:
Polypeptide backbones containing sugar residues at repetitive intervals are capable of binding the mannose receptor when said sugars are mannosyl, fucosyl, or N-acetyl glucosamine residues. These peptides are of the formula X-(Z(S)AAn1)n2-Y (I) wherein S represents a mannose, fucose, glucose or N-acetylglucosamine residue optionally coupled to a linker moiety; Z is the residue of an amino acid to which S is coupled; each AA is independently the residue of an additional amino acid, n1 is an integer = 1, 2 or 3; n2 is 3-15, and X and Y are noninterfering substituents. They are useful in the treatment of various diseases mediated by macrophage activity and proliferation.
Abstract:
Apparatus for continuously determining the areal density along a length of a material includes a radioactive source and a scintillating receiver. In a first embodiment, the invention measures the thickness of a traveling web simultaneously at multiple points across its full width. The apparatus includes a radioactive source (3) which extends across one side of the web (5). A detector array (6), on the opposite side of the web, detects the emission from the source through the web. The array includes scintillating fibers and multi- or single-anode photomultipliers (9) which may be connected by a scintillating or non-scintillating fiber optic elements (7) to the photomultiplier. In a second embodiment, the invention continuously detects the fill level of a plurality of containers as they are conveyed between the receiver and detector. A scintillating fiber receiver may have its fibers arranged either vertically or horizontally. When arranged horizontally, the fibers may be grouped and conduct photons to single anodes of a multi-anode photo-multiplier tube to provide direct physical measurement of the fill level. Still another receiver includes a plastic scintillator sheet directly coupled to a photomultiplier tube.

Low molecular weight polysaccharides related to dermatan sulfate have been shown to be the effective minimal structures to prevent or reduce coagulation in warm blooded animals.
Abstract:
Bordetella outer membrane proteins, vaccine compositions containing these proteins, and methods of administering the same are disclosed. The outer membrane proteins can be produced by recombinant means and expressed in an avirulent carrier microbe which may be used to immunize a subject of interest. The subject antigens provide a means for protecting against or treating Bordetella-induced diseases such as upper respiratory tract disease in turkey and chickens, atropic rhinitis in swine and dogs, and whooping cough in humans.
Abstract:
This invention provides a vaccine for the immunization of a vertebrate or invertebrate comprising an avirulent derivative of S. choleraesuis. The derivatives being substantially incapable of producing functional adenylate cyclase and/or cyclic AMP receptor protein. The invention also provides a vaccine for the immunization of a vertebrate and invertebrate comprising a virulent derivative of a pathogenic microbe said derivative being substantially incapable of producing functional adenylate cyclase and/or cyclic AMP receptor protein while being capable of expressing a recombinant gene derived from a pathogen of said vertebrate to produce an antigen capable of inducing an immune response in said vertebrate against said pathogen.
Abstract:
A microbial surface component recognizing adhesive matrix molecules (MSCRAMM) is disclosed which is characterized by its ability to bind to elastin, its inhibited activity in the presence of SDS and its enhanced activity in the presence of thiol reductants. More particularly, the MSCRAMM is bacterial in origin and is a member of the family of elastin binding proteins. In one embodiment, the MSCRAMM comprises a polypeptide having an amino acid sequence defined herein as SEQ ID NO:2, and extends to active fragments thereof. The role of MSCRAMMs in bacterial infection and its sequelae and related conditions is noted and the MSCRAMM may be prepared and used in diagnostic procedures and tests, including drug discovery assays, as well as in pharmaceutical compositions applicable for corresponding therapeutic methods. Both agonists and antagonists of the MSCRAMM are proposed and illustrated.

Abstract:
Electronics (40) implements the multiplicative noise model of the present invention. The diagnostic signal generator (50) processes the data signal s(t) to produce a diagnostic signal. The medium noise estimator (60) predicts repeatable noise components based on analysis of the diagnostic signal. Using the estimate of the medium noise, the precompensated signal generator (70) produces a corrected write signal.
