Abstract: A supplemental oxygen delivery system is described in which Aerosol is delivered into a housing which sits in the circuit from the supplemental oxygen supply and optional humidifier. The supplemental oxygen passes through this chamber in which the aerosol is located, and collects the aerosol transporting it to a patient via a nasal cannula or a face mask. An aerosol generator is mounted to the housing and delivers aerosol into an oxygen stream flowing between an inlet and an outlet of the housing. The housing also has a removable plug in the base thereof for draining any liquid that accumulates in the housing. There is no disruption of oxygen delivery to patients using nasal cannulas who currently have to use a separate face-mask when receiving nebulized medication.

In some examples, the apparatus includes a bolster, one or more support bars configured to place the bolster proximate to the popliteal fossa of the knee, and one or more straps or other attachment devices configured to removably attach the apparatus to the knee (or, area of the leg that includes the knee) of a patient.

Abstract: An aerosol generator is positioned adjacent to a patient as an attachment to a trocar. The trocar has an entry port for insufflation gas. Aerosol generated by a vibrating element is entrained in the insufflation gas and the mixture is delivered through the trocar. The aerosol may contain a medicament. The trocar may be a conventional trocar. Such trocars are typically used for a camera. The delivery of the aerosolized medicament can occur at the start of the procedure and be delivered in bolus. At the start of the procedure, the peritoneum is being inflated by means of the flow of insufflator gas. This gas flow will help to entrain the aerosolized medicament to the pneumoperitoneum regions. The surgeon can temporarily remove the camera from the trocar port to facilitate insertion and positioning of the aerosolizing unit.

Abstract: A projection apparatus is provided which is portable and scalable in size, and comprises a first projection device to direct a first program material towards a planar viewing film which is at least partially transparent and at least partially reflective, and which is mounted at an angle with respect to the viewing plane of a viewer, so as to create a virtual image. A rear screen is arranged in the viewing plane, behind the viewing film so as to exhibit second program material from a second projection device. The first program material and the second program material are edited and synchronized one with the other so that the virtual image is interrelated with the second program material on the rear screen, and provide an enhanced simulated 3D viewing.

Abstract: The Eph (erythropoietin-producing hepatocellular carcinoma) receptors and their cell surface anchored ligands, the Ephrins, comprise the largest of the receptor tyrosine kinases families with 14 receptors and 8 ligands. The receptors are subdivided into Eph-A and Eph-B categories and have known actions in the development of the vascular and nervous system. The present invention relates to an isolated mesenchymal stem cell selected from the group consisting of an isolated mesenchymal stem cell that expresses Ephrin-B2, an isolated mesenchymal stem cell that over-expresses Ephrin-B2, and an isolated mesenchymal stem cell that is genetically modified to increase Ephrin-B2 expression. The invention further relates to the various applications of the isolated mesenchymal stem cells of the present invention.

Abstract: A nebulizer 1 particularly for home use includes a housing 2 having an aerosol generator 3 mounted therein. The housing is closed by a hinged cap 4 and has an outlet 5 through which aerosol generated by the generator 3 is delivered. A suitable connector such as a mouthpiece 6 may be connected to the outlet 5. The housing 2 has a receiver for receiving a nebule 8.

The nebulizer cap 4 has a nebule opening device which may be in the form of a puncture pin 10 projecting therefrom to pierce the nebule 8 when the cap is moved to the closed position. The pin 10 is hollow or splined to regulate flow from the nebule. The nebulizer 1 also has a switch device for enabling operation of the aerosol generator 3 when the nebule 8 is opened. The switch device comprises a microswitch 12 on the housing which is engageable by a trigger 13 on the cap 4 when the cap is moved to the closed position.
