    Abstract: A method for removing hydrogen sulfide from a liquid stream is described. The method includes contacting the liquid stream including a first amount of hydrogen sulfide with a first side of a porous gas-liquid separation membrane. The hydrogen sulfide moves through the pores of the membrane from the first side to a second, opposite side of the membrane. The method further includes contacting a receiving fluid with the second, opposite side of the porous membrane to receive the hydrogen sulfide. The liquid stream is thus converted to a reduced-sulfide liquid stream having a second amount of hydrogen sulfide that is less than the first amount of hydrogen sulfide. A method for removing ammonia from a liquid stream is also described.

  • Patent number: 9856568
    Abstract: A pressurized rod anode having a hollow core that is monitored by a sensor. The hollow core is pressurized at all times, or in the alternative, is of a pressure less than the pressure within a reactor tank. A rod anode that fails to maintain pressure indicates material removal sufficient to breach the integrity of the rod anode. A relay can be used to cause removal of the rod anode power source when a breach of integrity occurs. Indicator lights provide instant monitoring of the rod anode condition, a bypass switch allow temporary operation of a rod anode pending a timed shutdown for repair.

  • Patent number: 9726659
    Abstract: Provided are methods for identifying or monitoring a subject having, or at risk of developing, impaired glucose homeostasis. Carboxy-4-methyl-5-propyl-2-furanpropanoic acid (CMPF) is shown to be a biomarker for impaired glucose homeostasis and/or conditions characterized by ?-cell dysfunction. Comparing a test level of CMPF in a subject to a control level identifies subjects having, or at risk of developing, impaired glucose homeostasis. Also provided are methods of causing impaired glucose homeostasis or ?-cell dysfunction and methods of screening for compounds that affect the activity of ?-cells. Also provided are methods for the treatment of ?-cell dysfunction by reducing the physiological levels of CMPF in a subject as well as the use of a OAT modulator for the treatment of ?-cell dysfunction.

  • Patent number: 9678076
    Abstract: The present invention, in some embodiments thereof, relates to methods and devices for determining a disease state in a patient. In some embodiments, human serum albumin may be analyzed for associated molecules, wherein the associated molecules are related to a disease such as cancer. Certain aspects of the invention are generally directed to devices and methods for determining a disease state as a function of the three-dimensional structure of a blood protein, human serum albumin (HSA) or its complex with other ligands, e.g., due to binding to disease-specific ligands. HSA interacts with biomolecules associated with a disease presence, and liganded HSA may differentially partition between aqueous phases of a predetermined partitioning system, wherein the partitioning behavior differs between HSA from healthy individuals and HSA from people harboring the predetermined disease, such as breast cancer.
