Methods are provided for the synthesis and secretion of recombinant proteins preferably large mammalian proteins or hetero-multimeric proteins at high levels and for prolonged time in polyploid, preferably diploid yeast. These methods use various mating competent yeast, including Pichia. In a preferred embodiment, a first expression vector is transformed into a first haploid cell; and a second expression vector is transformed into a second haploid cell. The transformed haploid cells, each individually synthesizing a non-identical polypeptide, are identified and then genetically crossed or fused. The resulting diploid strains are utilized to produce and secrete fully assembled and biologically functional hetero-multimeric protein.

This disclosure describes systems and methods for purging narrow diameter sensor tubing, occasionally referred to as “sensor lines”, in a ventilation system. The disclosure describes a novel approach in which a series of short, periodic releases of pressurized gas through the sensor tubes are used to clear any blockages due to condensation or patient secretions.

A high frequency pressure oscillation device that selective restricts the flow of breathing gas to or from a patient to produce pressure spikes in the patient's airway that facilitate clearing secretions from the patient's airway. The device includes a patient circuit that defines a closed path between a source of breathing gas and the patient's airway. A valve is disposed in the patient circuit such that in an open position the path between the source of breathing gas and the airway of the patient is substantially unobstructed. When the valve is in a closed position, the path between the source of breathing gas and the patient's airway is at least partially obstructed to create the pressure spikes. An actuating system associated with the valve alternatively places the valve in the open position and in the closed position at a predetermined oscillation rate that is independent of patient effort.

A gastrointestinal implant device is positioned in a patient's small intestine or rectum and produces an outward force that itself produces a distension signal which is a therapeutically useful neural or humoral signal that evokes satiogenic or weight loss effects by itself. The device may advantageously be placed in the duodenum adjacent the pylorus or in the jejunum, ileum or rectum. The distension signals may amplify chemosensory or mechanosensory signals such as enteroendocrine secretions within the patient. The device may be a mesh and include a low material density that allows for unrestricted chyme absorption within the small intestine and unrestricted chyme flow through the gastrointestinal system. A method includes inserting the device into the patient then either retrieving the device after treatment is complete or allowing a device formed of a biodegradable material to degrade in time after treatment is complete.
