Multiple Path Particle Dosimetry For Prediction Of Mouse Lung Deposition Of Nanoaerosol Particles, Mohammed Ali Sep 2019

Multiple Path Particle Dosimetry For Prediction Of Mouse Lung Deposition Of Nanoaerosol Particles, Mohammed Ali

Mohammed Ali

Nanoaerosolized particle (dia.<200 >nm) antibiotic inhalation therapy was tested to treat pneumonic tularemia in mice caused by Francisella novicida infection. Very limited experimental techniques are available to properly estimate inhaled doses and distribution of the drug inside the mouse lungs. To overcome this problem, computational simulation of particle deposition based on the Multiple Path Particle Dosimetry (MPPD) model was employed to simulate in vivo experimental conditions which included nasal breathing with whole body exposure to the antibiotic in the form of nano-aerosolized medicine. The deposition results were compared with several in vivo experimental data reported in literature; and satisfactory agreements …

Effects Of Three Dry Powder Inhalers On Deposition Of Aerosolized Medicine In The Human Oral-Pharyngeal-Laryngeal Regions, Mohammed Ali Sep 2019

Effects Of Three Dry Powder Inhalers On Deposition Of Aerosolized Medicine In The Human Oral-Pharyngeal-Laryngeal Regions, Mohammed Ali

Mohammed Ali

The dry powder inhaler (DPI) is a popular, effective and convenient drug delivery device for inhalation therapy to treat asthma. However, a large quantity (approximately 54%) of inhaled aerosols deposit in the oropharyngeal region. Deposition in this region is undesirable because it provides minimum therapeutic benefits and has adverse localized or systemic side effects. This study reports a method of examining electrostatic charge effects on deposition of three DPI aerosols (Spiriva™ Handihaler, Advair Diskus™, and Pulmicort™ Turbohaler) in a cadaver-based cast of the human oral-pharyngeal-laryngeal (OPL) regions. Experimental aerosols were generated from the three commercially available …

"Being Mindful" And Becoming A "Harmony Worker" During Unsettling Times.Docx Aug 2019

"Being Mindful" And Becoming A "Harmony Worker" During Unsettling Times.Docx

Carroy U "Cuf" Ferguson, Ph.D.

Let us be mindful of our individual and collective past in order to learn what works and does not work for our individual and collective Well Being.
Let us seek and find ways to experience Joy as a way "to be" in the present for our individual and collective Well Being.
And, let us create and implement Visions for evolving our consciousness in ways that can sustain our individual and collective Well Being.

Shining A Humanistic Light On Racism.Docx Jul 2019

Shining A Humanistic Light On Racism.Docx

Carroy U "Cuf" Ferguson, Ph.D.

On July 14, 2019, race-linked tweets, filled with racially charged negative rhetoric, began to emerge for a country, the United States, to grapple once more with its past, present, and future.  The tweets were directed toward four duly elected women of color in Congress.  In this light, the phenomenon of racism, yet again, was abruptly made more overt, rather than covert.  Indeed, it is fair to say that the phenomenon of racism is often an "unconscious or veiled phenomenon" for some.

Reimagining Icarus: Ethics, Law And Policy Considerations For Commercial Human Spaceflight, Sara M. Langston May 2019

Reimagining Icarus: Ethics, Law And Policy Considerations For Commercial Human Spaceflight, Sara M. Langston

Sara Langston

Commercial human spaceflight presents an area for engaging novel human activity and objectives, to include space exploration, entertainment, transportation and extraterrestrial resource acquisition. The inherent dangers and lack of scientific and medical certainty involved however raise interrelated questions of ethics, bioethics, law and public policy. This is particularly the case with spaceflight participant (SFP) screening, selection, and commercial human spaceflight activities where regulations are currently silent or lacking. In the absence of established law, ethics can play an important role by informing industry standards, policies and best practices. Understanding the fundamental ethical values at stake in the application of new …
