  • Patent number: 9023887
    Abstract: The present invention relates to methods for treating pancreatitis and/or organ failure comprising administering, to a subject in need of such treatment, an effective amount of a lipase inhibitor. It is based, at least in part, on the discoveries that lipotoxicity contributes to inflammation, multisystem organ failure, necrotic pancreatic acinar cell death and in acute pancreatitis, and that inhibition of lipolysis was able to reduce indices associated with these conditions. Accordingly, in various embodiments, the present invention provides for methods and compositions for limiting lipotoxicity and thereby reducing the likelihood of poor outcomes associated with acute pancreatitis and other severe systemic conditions, especially in obese individuals.

  • Publication number: 20150119850
    Abstract: Methods for maintaining patency in a bronchus of a patient are presented. A catheter is positioned within the bronchus. A target region of one or more of a bronchial wall, submucosa, media, and adventitia is punctured at or adjacent a location of a debulked bronchial carcinoma with an injection needle disposed on a distal end of the catheter. Such puncturing is achieved by expanding a balloon disposed on the distal end of the catheter. The balloon is comprised of at least two materials of different elastic modulus, which allows for a flexible but relatively non-distensible, unfolding component of the balloon as well as an elastomeric, inflatable component of the balloon. Through the injection needle, an amount of cytotoxic, cytostatic, or anti-neoplastic agent is delivered to the target region. The delivered amount is effective to limit by a therapeutically beneficial amount recurrent bronchial occlusion due to recurrence of the bronchial carcinoma.

  • Publication number: 20150118311
    Abstract: Brain-penetrating polymeric nanoparticles that can be loaded with drugs and are optimized for intracranial convection-enhanced delivery (CED) have been developed. In the preferred embodiment, these are loaded with FDA-approved compounds, identified through library screening to target brain cancer stem cells (BSCSs). The particles are formed by emulsifying a polymer-drug solution, then removing solvent and centrifuging at a first force to remove the larger particles, then collecting the smaller particles using a second higher force to sediment the smaller particles having a diameter of less than 100 nm, more preferably less than 90 nanometers average diameter, able to penetrate brain interstitial spaces.
