  • Publication number: 20200016097
    Abstract: The present invention provides methods of protecting irradiated eukaryotic cells such as irradiated mammalian epithelial cells, from the deleterious effect of microbial pathogens such as Pseudomonas aeruginosa. The invention also provides methods of protecting irradiated organisms from such deleterious effects, resulting in reduced mortality and morbidity. Further provided are kits containing relatively high molecular weight biocompatible polymers such as polyethylene glycol, optionally supplemented with a protective polymer such as dextran and/or essential pathogen nutrients such as L-glutamine, along with instructions for administration to organisms to be exposed to radiation.

  • Publication number: 20180110639
    Abstract: A medical system for the treatment of morbid obesity comprising an inflatable balloon implanted in a gastric cavity, a percutaneous fillant delivery tube and a control module connected to the tube for regulating the inflation and deflation of the balloon. The balloon may be individually contoured and inflated to occupy a large volume of the gastric cavity to provide a feeling of satiety. The balloon may also be deflated to give the gastric cavity lining a rest during less critical time.

  • Patent number: 9937199
    Abstract: Materials and methods for preventing and treating anastomotic leaks are disclosed. Data establishes that pathogenic microbes interfere with establishing epithelial cell barriers in anastomoses and, more generally, with the reconnection of any two portions of like or different tissues comprising epithelia. Suitable prophylactic and therapeutic composition comprise, e.g., a phosphorylated high molecular weight polyethylene glycol compound.

  • Publication number: 20170281668
    Abstract: The present invention provides pharmaceutical compositions in the form of relatively high molecular weight biocompatible polymers such as polyethylene glycol, optionally supplemented with a protective polymer such as dextran and/or essential pathogen nutrients such as L-glutamine. Also provided are methods for preventing or treating gut-derived sepsis attributable to intestinal pathogens such as Pseudomonas aeruginosa by administering high molecular weight polyethylene glycol as well as methods for monitoring the administration of high molecular weight polyethylene glycol, such as in methods of preventing, ameliorating or treating microbe-induced epithelial disorders, as exemplified by gut-derived sepsis. Frequently, gut-derived sepsis arises as a complication in mammals recovering from surgical intervention or suffering from a disease or disorder, providing indications of suitable animals to receive preventative treatment.
