  • Publication number: 20220187293
    Abstract: Embodiments provide for devices and methods of use for detecting one or more biomarkers of rheumatic disease in a subject. In an example, a method includes detecting citrullinated human serum albumin (HSA) in a biological sample via obtaining the biological sample from a subject, applying the biological sample to a lateral flow device under conditions sufficient for formation of an immunocomplex comprising anti-HSA antibody coupled to citrullinated HSA that is in turn coupled to anti-citrullinated HSA autoantibody, determining a quantity of the immunocomplex, and managing rheumatic disease associated with the subject. In this way, rheumatic disease may be effectively managed based at least in part on amounts of citrullinated HSA detected via rapid point-of-care test methodology.

  • Publication number: 20110218230
    Abstract: This disclosure provides an intracellular fragment of natriuretic peptide receptor A (NPRA), referred to herein as soluble natriuretic peptide receptor-related fragment (sNRF). It is shown herein that sNRF causes NP resistance. Based on these observations, methods of treating a cardiovascular disorder by inhibiting the activity of sNRF are disclosed. Assays are provided that use sNRF to screen agents for their ability to increase the biological activity of an NPR, for example agents that increase the sensitivity of NPR for NPs (such as atrial natriuretic peptide, ANP), or that decrease growth factor deleterious effects, or combinations thereof. Also provided are agents identified using the disclosed assays, and methods of using the agents, for example to treat or diagnose a cardiovascular disorder, such as heart failure.

  • Publication number: 20080206231
    Abstract: The present invention discloses for the first time that the insulin receptor (IR) is a target of Herstatin, which modulates IR and IR-mediated intracellular signaling. In preferred aspects, Herstatin binds at nM concentrations to cell-surface IR, up-regulates basal IR expression by several-fold, induces the accumulation of pro-IR, and stimulates insulin activation of the ERK pathway. Moreover, these changes in insulin signaling are accompanied by alterations in IGF-IR expression, IRS-2 levels, and the serine phosphorylation state of both IRS-1 and IRS-2.

  • Patent number: 5988950
    Abstract: A system for preventing upward migration of contaminants in soil having capillary pores defined therein, the system comprising the soil and a hydrophobic substance applied to the soil, the substance being attracted to enter the capillary pores so that a barrier is formed which, under unsaturated soil conditions, prevents the upward migration of contaminants carried by water through the capillary pores in the soil.

  • Patent number: 5951204
    Abstract: A process for removing water-soluble contaminates from soil includes laying a mat over and in contact with the contaminated soil, applying water to the soil, permitting the water to be transferred from the soil to the mat, permitting the contaminants to be carried via the water into the mat, and permitting the water to be evaporated from the mat so that the contaminants precipitate in the mat.

  • Patent number: 5794698
    Abstract: A system and method for removing light non-aqueous liquids via a wellbore from at least a water-saturated subterranean zone using an oleophilic absorbent wick by positioning the wick in a wellbore extending from the surface through at least a portion of the subterranean water-saturated zone; reducing the pressure in the wellbore and removing vaporized light non-aqueous liquids from the wellbore.
