Abstract: In one aspect the present invention is directed to mutant Neutrophil gelatinase-associated lipocalin (NGAL) proteins that have the ability to bind to siderophores, such as enterochelin, and to chelate and transport iron, and that are excreted in the urine. Such NGAL mutants, and complexes thereof with siderophores, can be used to clear excess iron from the body, for example in the treatment of iron overload. The NGAL mutants of the invention also have antibacterial activity and can be used in the treatment of bacterial infections, such as those of the urinary tract.

Abstract: Optical imaging or spectroscopy described can use laminar optical tomography (LOT), diffuse correlation spectroscopy (DCS), or the like. An incident beam is scanned across a target. An orthogonal or oblique optical response can be obtained, such as concurrently at different distances from the incident beam. The optical response from multiple incident wavelengths can be concurrently obtained by dispersing the response wavelengths in a direction orthogonal to the response distances from the incident beam. Temporal correlation can be measured, from which flow and other parameters can be computed. An optical conduit can enable endoscopic or laparoscopic imaging or spectroscopy of internal target locations. An articulating arm can communicate the light for performing the LOT, DCS, or the like. The imaging can find use for skin cancer diagnosis, such as distinguishing lentigo maligna (LM) from lentigo maligna melanoma (LMM).

Abstract: A heating and/or cooling temperature adjusting apparatus disposed proximate a point of use comprising a heat exchange structure, at least one thermal mass unit comprised of a material which changes phase at a predetermined temperature, and a housing which at least partially encloses the heat exchange structure and thermal mass unit. Additionally, a plurality of thermal mass units can be employed, each with equivalent, or differing, temperature threshold points for conversion between solid, liquid or gaseous phases. The presence of the thermal mass unit at the point of use allows for the heating/cooling system to rapidly adjust the temperature of the room while simultaneously decreasing the duty cycle of the heating/cooling generator (e.g. boiler).

Abstract: Systems and methods of performing temperature swing solvent extraction (TSSE) descaling of produced water and desalination of high-salinity brines, e.g., those having a total dissolved solids (TDS) greater than about 250,000 ppm are capable of producing descaled water products including less than about 5% weight percent TDS. The brine/produced water feedstreams and combined with a solvent having temperature-dependent water solubility at a temperature TL. Water is extracted from the feedstream into the solvent to form a water-in-solvent extract component and a raffinate component, from which a solid phase can be precipitated as more water is portioned in the solvent and basicity increases. Heating of the water-in-solvent extract component reduces the solubility of the water therein, producing a biphasic mixture of dewatered solvent and descaled water that can be separated.
