Jeremiah And Falsehood, Ernesto A Guajardo

Electronic Theses and Dissertations

This thesis proposes that falsehood within Jeremiah is the culminating socio- theological development of a string of habitual and willful degradations done to Judah’s agency by its collective religious and public parties. Jeremiah’s inherent historical context being imbedded within the ancient Near East, and his intentional cross-comparison of Judah’s prophets with that of Samaria, calls for a reconsideration of Jeremiah’s standard reading to one that includes non-Israelite divination, prophecy, and ideas on the divine presence. Judah’s prophets and priests are specifically mentioned repeatedly throughout the text as being the encouragers of and sustainers of Judah’s idolatry, immoral behavior, false prophecy, …

Investigating The Role Of Tetherin Protein In Multivesicular Bodies Fusions In Lung Cancer Cells, Md. Rakib Miah

Electronic Theses and Dissertations

Cells rely on the secretion of exosomes to communicate with one another and this process is potentially mediated by a protein called tetherin, which anchors exosomes to the cell surface to limit their spread. Tetherin protein has attracted a lot of attention because of its capacity to hinder the propagation of viruses by attaching virions to the surface of host cells. Treatment with interferon-alpha (IFNα) increases the production of tetherin, although it is not known how this affects tetherin localization and exosome-mediated communication. This thesis looks at how the expression of tetherin, which IFNα boosts, affects the dynamics of intercellular …
