  • Publication number: 20230241342
    Abstract: Aspects of the present technology comprise a positioning and stabilising structure to hold a seal-forming structure in a therapeutically effective position on a head of a patient. The seal-forming structure may be constructed and arranged to form a seal with a region of the patient's face surrounding an entrance to the patient's airways for sealed delivery of a flow of air at a therapeutic pressure of at least 4 cmH2O with respect to ambient air pressure throughout the patient's respiratory cycle in use.

  • Patent number: 8871516
    Abstract: The present invention is directed to a method for preparing an expression vector encoding a tailored recombinase, wherein said tailored recombinase recombines asymmetric target sites within the LTR of proviral DNA of a retrovirus inserted into the genome of a host cell and is useful as means for excising the provirus from the genome of the host cell. The present invention further relates to an in vitro-method of optimising the treatment of a retroviral infection of a subject and to the use of tailored recombinases for the preparation of pharmaceutical compositions for reducing the viral load in a subjected infected by a retrovirus.
