  • Patent number: 11918748
    Abstract: A respiratory assistance apparatus has a gases inlet configured to receive a supply of gases, a blower unit configured to generate a pressurised gases stream from the supply of gases; a humidification unit configured to heat and humidify the pressurised gases stream; and a gases outlet for the heated and humidified gases stream. A flow path for the gases stream extends through the respiratory device from the gases inlet through the blower unit and humidification unit to the gases outlet. A sensor assembly is provided in the flow path before the humidification unit. The sensor assembly has an ultrasound gas composition sensor system for sensing one or more gas concentrations within the gases stream.

  • Publication number: 20120021925
    Abstract: The application refers to a method for diagnosing prostate cancer through the measurement of the combination of PSP94 (?-microseminoprotein) and F/T PSA biomarkers, the method using urine samples to measure PSP94 and serum samples to analyse F/T PSA. In one embodiment, the PSP94 is standardized to creatinine. Also based on the measurement of PSP94 and F/T PSA are provided methods and kits for (a) diagnosing aggressive prostate cancer; (b) differential diagnosis; and (c) diagnosing the progression of prostate cancer.

  • Publication number: 20100216654
    Abstract: The present invention includes biomolecules and use of these biomolecules for differential diagnosis of prostate cancer and/or non-malignant disease of the prostate. In an embodiment, the present invention provides methods for detecting biomolecules within a biological sample as well as a database comprising of mass profiles of biomolecules specific for healthy subjects, subjects having a non-malignant disease of the prostate and subjects having prostate cancer. The invention further includes kits for differential diagnosis of prostate cancer and/or non-malignant disease of the prostate in a biological sample.

  • Publication number: 20050283936
    Abstract: A cleaning apparatus for cleaning a surface in which cleaning solution is dispensed to the surface and substantially simultaneously extracted along with the dirt on the surface in a continuous operation is provided. The cleaning apparatus includes a housing and a recovery tank removably mounted to the housing. A liquid distribution system is operatively associated with the housing for distributing the cleaning solution to the surface. A suction nozzle is secured to the housing and in fluid communication with the recovery tank. A suction source is in fluid communication with the suction nozzle for generating suction to draw dirt and liquid through the suction nozzle and into the recovery tank. The suction nozzle includes a front nozzle portion removably mounted to a rear nozzle portion.

  • Publication number: 20050015834
    Abstract: An inbred corn line, designated SE8505, is disclosed. The invention relates to the seeds of inbred corn line SE8505, to the plants of inbred corn line SE8505 and to methods for producing a corn plant, either inbred or hybrid, by crossing the inbred line SE8505 with itself or another corn line. The invention further relates to methods for producing a corn plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other inbred corn lines derived from the inbred SE8505.
