Abstract:
The present invention discloses the existence of two novel proteins UspA1 and UspA2, and their respective genes uspA1 and uspA2. Each protein encompasses a region that is conserved between the two proteins and comprises an epitope that is recognized by the MAb 17C7. One or more than one of these species may aggregate to form the very high molecular weight form (i.e. greater than 200 kDa) of the UspA antigen. Compositions and both diagnostic and therapeutic methods for the treatment and study of M. catarrhalis are disclosed.
Abstract:
Open tubular capillary columns for liquid and ion chromatography, based upon an ionically impermeable polyolefin capillary having a bore with a sulfonate-group- or amine-group-functionalized internal surface. The capillary columns may include a coating of ion exchanging nanoparticles electrostatically bound to the functionalized internal surface. The capillary columns may be made by exposing the interior surface to a sulfonating reagent comprising chlorosulfonic acid (CISO3H), preferably from 85 wt % to 95 wt % chlorosulfonic acid at a process temperature of 20 to 25° C. The interior surface may be subsequently exposed to an asymmetrical diamine to form a sulfonic mid-linkage to the diamine, i.e., to form a sulfonamide-linked, amine-group-functionalized internal surface. The coating may be provided by subsequently exposing the interior surface to an aqueous suspension of ion exchanging nanoparticles to electrostatically bond the ion exchanging nanoparticles to the functionalized internal surface.
Abstract:
The present invention provides methods for inhibiting the degeneration of retinal pigment epithelial cells, which can reduce the incidence of, or delay the onset of, age-related macular degeneration, particularly in the early stages of AMD or in individuals at high risk for the disease.
Abstract:
Antagonists of null4 integrin/null4 integrin ligand adhesion, which inhibit the biological effects of such adhesion are described and methods for their use are detailed. Such antagonists are useful in suppressing bone destruction associated with multiple myeloma. The homing of multiple myeloma cells to bone marrow and their null4 integrin-dependent release of bone-resorbing factors, resulting in bone destruction in patients with multiple myeloma, is inhibited.
Abstract:
Gas monitoring network and deployment systems and methods are described for detecting gas leaks (e.g., natural gas leaks) from gas infrastructures (e.g., buried natural gas) within residential, commercial, rural, and industrial areas. A method of deployment involves placing detector systems indoor and outdoor environments in distinct patterns, providing early warning or long-term monitoring of gas leaks via data communication technologies.
