Novel Architecture Of Costal Cartilage And Implications In Chest Wall Deformities, Anthony J. Asmar
Novel Architecture Of Costal Cartilage And Implications In Chest Wall Deformities, Anthony J. Asmar
Biological Sciences Theses & Dissertations
Costal cartilage is a type of hyaline cartilage that forms rod-like structures that connect the ribs to the sternum. Deformation of costal cartilage is observed in the chest wall deformities, pectus excavatum and pectus carinatum. Pectus excavatum involves a sternal displacement causing a depression of the chest while pectus carinatum causes a protrusion of the chest. As costal cartilage is not a widely studied tissue, this leaves little knowledge into possible factors involved in the pathogenesis of pectus deformities. Costal cartilage in these deformities has been described as being weakened and may implicate proteoglycans which play an important role in …
Structural And Functional Study Of Multidrug Membrane Transporters, Feng Ding
Structural And Functional Study Of Multidrug Membrane Transporters, Feng Ding
Theses and Dissertations in Biomedical Sciences
Multidrug membrane transporters (efflux pumps) in both prokaryotes and eukaryotes are responsible for ineffective treatment of a wide variety of diseases, including infections and cancer, underscoring the importance of better understanding of their structures and functions for design of effective therapies. Despite extensive studies over decades, their underlying molecular mechanisms remain largely unknown. In this dissertation, we focus on the study of structures and functions of multidrug membrane transporters, including ATP-binding cassette transporter (BmrA) and Resistance-Nodulation-Cell Division transporter (MexA,B-OprM) in gram-positive and gram-negative bacteria ( Bacillus subtilis and Pseudomonas aeruginosa), respectively. We fused EGFP with N-terminus and C-terminus of …
