Interaction Forces And Reaction Kinetics Of Ligand-Cell Receptor Systems Using Atomic Force Microscopy, Anwesha Sarkar
Interaction Forces And Reaction Kinetics Of Ligand-Cell Receptor Systems Using Atomic Force Microscopy, Anwesha Sarkar
Wayne State University Dissertations
Atomic Force Microscopy (AFM) provides superior imaging resolution and the ability to measure forces at the nanoscale. It is an important tool for studying a wide range of bio-molecular samples from proteins, DNA to living cells. We developed AFM measurement procedures to measure protein interactions on live cells at the single molecular level. These measurements can be interpreted by using proper statistical approaches and can yield important parameters about ligand-receptor interactions on live cells. However, the standard theory for analyzing rupture force data does not fit the experimental rupture force histograms. Most of the experimental measurements of rupture force data …
Dna Aptamers Selected Against Wild-Type Helix 69 Ribosomal Rna And Their Implications In Combating Antibiotic Resistance, Sakina Miriam Hill
Dna Aptamers Selected Against Wild-Type Helix 69 Ribosomal Rna And Their Implications In Combating Antibiotic Resistance, Sakina Miriam Hill
Wayne State University Dissertations
Outbreaks of advanced antibiotic-resistant strains of microbes have hastened the need to identify new viable molecular targets for the development of novel anti-infectives. For this purpose, helix 69 (H69, or m3a 19-nucleotide (nt) hairpin motif that is highly conserved throughout phylogeny and rich in modified nucleotides, including pseudouridine () and 3-methylpseudouridine (m3) was chosen as a potential target. Helix 69, which is located in domain IV of Escherichia coli 23S ribosomal RNA (rRNA), undergoes conformational changes when in close proximity to the decoding region of 16S rRNA and transfer RNAs (tRNAs) in the peptidyl-transferase center (PTC). Functionally, the exact biological …
Dynamics Of Biopolymers On Nanomaterials Studied By Quasielastic Neutron Scattering And Mdsimulations, Gurpreet Dhindsa
Dynamics Of Biopolymers On Nanomaterials Studied By Quasielastic Neutron Scattering And Mdsimulations, Gurpreet Dhindsa
Wayne State University Dissertations
Neutron scattering has been proved to be a powerful tool to study the dynamics of biological systems under various conditions. This thesis intends to utilize neutron scattering techniques, combining with MD simulations, to develop fundamental understanding of several biologically interesting systems. Our systems include a drug delivery system containing Nanodiamonds with nucleic acid (RNA), and two specific model proteins, β-Casein and Inorganic Pyrophosphatase (IPPase).
RNA and nanodiamond (ND) both are suitable for drug-delivery applications in nano-biotechnology. The architecturally flexible RNA with catalytic functionality forms nanocomposites that can treat life-threatening diseases. The non-toxic ND has excellent mechanical and optical properties and …

Apoptosis is the energy dependent programmed cell death. Improper function of apoptosis could lead to diseases such as cancers, strokes, Alziemer’s disease. Caspases are the enzymes involved in the later stage of this process. Peptidyl and non-peptidyl caspase inhibitors have been synthesized recently. These non-peptidyl compound classes which consist of pyrrolidinyl-5-sulfo isatins have showed a greater potency against executioner caspases, caspase-3 and -7. According to literature and for further …
