The Wet Bridge Transfer System: An Novel In Vitro Tool For Assessing Exogenous Surfactant As A Pulmonary Drug Delivery Vehicle, Brandon J. Baer
The Wet Bridge Transfer System: An Novel In Vitro Tool For Assessing Exogenous Surfactant As A Pulmonary Drug Delivery Vehicle, Brandon J. Baer
Western Research Forum
Background:
Due to its complex branching structure, direct drug delivery to the remote areas of the lung is a major challenge. Consequently, most therapies, such as those treating pulmonary infection and inflammation, must utilize large systemic dosing, with the potential for adverse side effects. A novel alternative strategy is to use exogenous surfactant, a material capable of distributing throughout the lung, as a pulmonary drug delivery vehicle.
Objective:
Utilize an in vitro transferring system to assess exogenous surfactant (BLES) as a pulmonary delivery vehicle for different therapeutics.
Methods:
An in vitro technique was developed to simultaneously study surfactant delivery and …
Investigating The Pathogenesis Of Staphylococcus Aureus In Periprosthetic Joint Infections, Santiago L. Iglesias
Investigating The Pathogenesis Of Staphylococcus Aureus In Periprosthetic Joint Infections, Santiago L. Iglesias
Electronic Thesis and Dissertation Repository
The most challenging complication after total joint replacement is the periprosthetic joint infection (PJI). Staphylococcus aureus is a commensal bacterium and a human pathogen. It is responsible for more than half of the PJI. We demonstrated that synovial fluid has antimicrobial properties against S. aureus and the iron restriction is one of the mechanisms used for the host to prevent bacterial growth, and is even able to increase killing of S. aureus. We have shown a clear role of transferrin as a restrictive factor in synovial fluid that functions by iron starving the bacteria and sensitizing them to killing …

Analysis Of Invariant Natural Killer T Cells In Intra-Abdominal Sepsis, Ram Venkatesh Anantha
Electronic Thesis and Dissertation Repository
Sepsis is characterized by a severe systemic inflammatory response to infection that is associated with high morbidity and mortality despite optimal care. Invariant natural killer T (iNKT) cells are potent regulatory lymphocytes that can produce pro- and/or anti-inflammatory cytokines, thus shaping the course and nature of immune responses; however, little is known about their role in sepsis. We demonstrate here that patients with sepsis/severe sepsis have significantly elevated proportions of circulating iNKT cells in their peripheral blood, as compared to non-septic patients. We therefore investigated iNKT cells in mice with intra-abdominal sepsis (IAS). Our data show that iNKT cells are …
