Design, Synthesis, And Biological Evaluation Of Small Molecule Drug Conjugates Targeting The Carbonic Anhydrase Ix Receptor And Investigation Of A Ligand Targeted Strategy For Targeted Cell-Based Therapies, Isaac Marks

Open Access Dissertations

Carbonic anhydrase IX (CAIX) is a membrane-spanning zinc metalloenzyme that catalyzes the reversible consumption of CO2 and water to form H+ + HCO3- in hypoxic and acidic environments. Many human cancers upregulate CAIX to help control their pH in hypoxic microenvironments. The consequent overexpression of CAIX on malignant cells and low expression on normal tissues renders CAIX a particularly attractive target for small molecule inhibitors, antibody drug conjugates, and ligand-targeted drugs.

Exploring The Role Of Reflexivity In Supporting Preservice Elementary Teachers' Conceptions Of Science As Socially And Culturally Embedded, Jeffrey Radloff

Open Access Dissertations

Achieving widespread scientific literacy has been a longstanding goal of US science standards, requiring that students and teachers possess contemporary nature of science (NOS) conceptions. However, NOS conceptions are repeatedly found to be wide-ranging or ‘naïve’, resulting in regular efforts by science education researchers to hone, or standardize them. While this has improved some aspects of NOS conceptions, others remain relatively unchanged, specifically within prospective, or preservice elementary teacher populations.

One unaffected aspect concerns preservice science teachers’ views of science as socially and culturally embedded, or mutually connected with changes in society and culture. However, understanding this facet of NOS …
