This experimental investigation was undertaken to quantify the electrostatic charge and aerodynamic size distribution of the medicinal drug particles inhaled through an in-vitro mouth-throat (MT) in order to compare the amount of drugs can be delivered to the human lung while mimicking a patient is either sitting or lying. The MT model is a cadaver-based replica cast of human oral-pharyngeal-laryngeal region. Tested drug aerosols were generated by a commercially available metered dose inhaler (MDI). The MT model was placed inside a humidity (95%) and temperature (37oC) controlled chamber. Its mouth-inlet was positioned horizontally and vertically to simulate sitting …

Honors Theses

Vaccines represent one of the most significant medical innovations of the 20th century, resulting in the eradication or near eradication of a handful of deadly diseases. However, many infectious diseases remain resistant to effective vaccination, largely due to a lack full immune activation by traditional protein-based vaccines. A promising alternative vaccination strategy is the emerging development of DNA vaccines, which rely upon the delivery of exogenous genetic material to host cells encoding for a viral or bacterial antigen in order to induce a robust immune response by closely mimicking live infection. The delivery of genetic material requires a carrier …
