Abstract: A novel canola protein isolate consisting predominantly of 2S canola protein and having equal to better solubility properties and improved clarity properties, has an increased proportion of 2S canola protein and a decreased proportion of 7S canola protein. The novel canola protein isolate is formed by heat treatment or isoelectric precipitation of aqueous supernatant from canola protein micelle formation and precipitation, to effect precipitation of 7S protein which is sedimented and removed. Alternatively, the novel canola protein isolate may be derived from a selective membrane procedure in which an aqueous canola protein solution containing 12S, 7S and 2S canola proteins is subjected to a first selective membrane technique to retain 12S and 7S canola proteins in a retentate, which is dried to provide a canola protein isolate consisting predominantly of 7S canola protein, and to permit 2S canola protein to pass through the membrane.

Abstract: A process for leaching a value metal from a base metal sulfide ore, comprising the step of leaching the ore with a lixiviant comprising a chloride, an oxidant and hydrochloric acid is disclosed. The leaching is controlled, by use of low concentrations of hydrochloric acid and a redox potential, to effect formation of hydrogen sulfide from the base metal sulfide ore. The hydrogen sulfide is stripped from the leach solution, thereby reducing the amount of sulfate generated in the leach to very low levels. The leaching may also be conducted to limit the co-dissolution of platinum group metals and gold with the base value metals. The leach forms a value metal-rich leachate and a solids residue. The solids residue may be subsequently leached to recover the platinum group metals and gold. The value metal-rich leachate can be oxidized and neutralized to recover the value base metals. In an embodiment, the chloride is magnesium chloride and lixiviant solution is regenerated.

Abstract: A canola protein isolate having a protein content of at least about 90 wt % (N×6.25), preferably at least about 100 wt %, and consisting predominantly of the 2S protein and substantially free from the 7S and 12S proteins is prepared. In one aspect, canola oil seed meal is extracted with aqueous protein solution at an elevated temperature to preferentially extract 2S protein from the meal to produce a canola protein solution containing predominantly 2S protein. The 2S canola protein is recovered as an isolate. In another aspect, the canola oil seed meal is extracted with aqueous saline solution to extract 2S, 7S and 12S proteins from the meal. The aqueous protein extract solution is heat treated at an elevated temperature to precipitate 7S and 12S proteins and leave a 2S protein solution from which the isolate may be recovered. In a further aspect, the aqueous protein solution is concentrated prior to the heat treatment.

The invention also encompasses an in vivo method of preparing an animal model of human schizophrenia. Such a model is useful for screening and identifying therapeutic agents for treating human schizophrenia.

Abstract: The present invention relates to analytical methods, platforms, and devices for the rapid and efficient immunochromatic determination of one or more components in fluid samples. The devices are especially useful for identifying analytes in small volumes of whole blood samples utilizing one membrane principally for separating particles such as red blood cells from plasma and a second membrane as the site for reactions to identify the analytes.

Abstract: A web processing machine permitting inspection and repair of a roll of web material includes an inspection zone vertically juxtaposed to a splicing zone. The inspection zone is structured to be removed from the juxtaposed position to a retracted position in which the splicing zone is exposed to permit an operator to perform a modification of the web without having to substantially move physically from the position in which the operator was located to perform inspection while the machine is running.

Abstract: Flax and linola oil seed protein isolated are provided. Such isolates are made by extracting flax and linola oil seed protein from the oil seed meal, concentrating the aqueous protein solution, diluting the concentrated protein solution to form protein micelles, collecting mass. Further flax protein isolate may be recovered from the supernatant from the protein micellar formation. The protein isolated have a protein content of at least about 90 wt % (N ×6.25), preferably at least about 100 wt %, on a dry weight basis.

Abstract: Automatic ongoing adjustment of the cycling-off time of ventilator inflation phase during assisted ventilation in accordance with true respiratory rate of a patient. Electrical signals are generated corresponding to the gas flow exchanged between patient and ventilator (flow) and/or to airway pressure (Paw) and the true respiratory rate of the patient (patient RR) is determined on an ongoing basis from the flow and/or Paw. The current average cycle duration of patient respiratory efforts (current patient TTOT) is estimated from patient RR. A current desirable duration of the inhalation phase (desirable TI) is calculated from the product of current patient TTOT a TI/TTOT ratio chosen to be in the physiological range, usually 0.25 to 0.50. The ventilator phase is caused to terminate in accordance with the desirable TI.

Abstract: Oil seed protein isolates, particularly canola protein isolate, are produced at a high purity level of at least about 100 wt % (N×6.25) by a process wherein oil seed protein is extracted from oil seed meal, the resulting aqueous protein solution is concentrated to a protein content of at least about 200 g/L, and the concentrated protein solution is added to chilled water having a temperature below about 15° C. to form protein micelles, which are settled to provide a protein micellar mass (PMM). The protein micellar mass is separated from supernatant and may be dried. The supernatant may be processed to recover additional oil seed protein isolate by concentrating the supernatant and then drying the concentrated supernatant, to produce a protein isolate having a protein content of at least about 90 wt %. The concentrated supernatant may be mixed in varying proportions with at least part of the PMM and the mixture dried to produce a protein isolate having a protein content of at least about 90 wt %.

Abstract: Substantially pure 2S canola protein is obtained substantially free from 7S and 12S canola protein by a procedure in which 2S canola protein is captured by binding to a cation-exchange medium while permitting other proteins and impurities to be washed away. The 2S canola protein then is removed from the cation-exchange medium by exposure of the cation-exchange medium to saline at a suitably high salt concentration.
