Attachment Sites Of Irreversible Cocaine Analogs On The Dopamine Transporter, Rejwi Acharya Dahal

Theses and Dissertations

The dopamine transporter (DAT) is an integral membrane protein that reuptakes dopamine (DA) from the extracellular space into the presynaptic neuron. DAT regulates dopaminergic neurotransmission as it maintains homeostatic synaptic DA levels in the brain. Psychostimulants such as cocaine disrupt DA homeostasis as it binds to DAT and prevents reuptake of DA. Excess DA in the synapse leads to prolonged dopaminergic neurotransmission, which is associated with cocaine related euphoria often leading to addiction.

The DAT consists of 12 transmembrane domains (TMs) with N- and C-termini facing the cytoplasm. TMs 1, 3, 6, and 8 make up the core of the …

Study Of Surface Modification Of Tungsten Nanostructures For Superhydrophobic Applications, Richard Alletru

Theses and Dissertations

In this work, we studied the impact of the modification of the structure of tungsten surfaces through physical vapor deposition (magnetron sputtering), electrochemical (anodization and electropolishing), and thermal (annealing) processes on the wettability of the designed surfaces. We observed static contact angle values ranging from around 10° to above 150° showing the importance of the techniques used to produce the surfaces. We noticed that the annealing process tends to increase the wettability, transforming hydrophobic surfaces into hydrophilic surfaces. We also observed that electropolishing affects the wettability in such a way that the contact angles of pre-chemically treated tungsten foils tend …

The Osh Family Of Proteins And Their Role In Caloric Restriction-Mediated Lifespan Extension In The Budding Yeast Saccharomyces Cerevisiae, William Douglas Craft

Theses and Dissertations

Oxysterol-binding protein homolouges (OSH) have been implicated in mediating non-vesicular sterol transport. Caloric restriction (CR) down-regulates sterol synthesis in a variety of organisms, including the budding yeast Saccharomyces cerevisiae. OSH6, when up-regulated, extends replicative lifespan. In contrast, OSH5 up-regulation shortens replicative lifespan. In this thesis I obtained evidence to show that the deletion of OSH5 extends replicative lifespan in normal media. Deletion of OSH5 in the presence of caloric restriction blocks the lifespan-extending properties of the CR media. My data demonstrate that the total cellular sterol levels of the longevity mutants are indistinguishable from that of wild type. This suggests …

Differential Effects Of Endocannabinoid Catabolic Inhibitors On Opioid Withdrawal In Mice, Thomas Gamage

Theses and Dissertations

The effects of cannabinoids in reducing somatic signs of opioid withdrawal have been known for some time. In morphine dependent rodents, opioid withdrawal following precipitation with the mu opioid antagonist naloxone elicits robust withdrawal behaviors including jumps, paw flutters, head shakes, diarrhea and weight loss. Delta-9-tetrahydrocannabinol has been shown to reduce this opioid withdrawal in mice via activation of the cannabinoid type-1 (CB1) receptor and recently it has been shown that inhibition of the catabolic enzymes for endocannabinoids also reduce somatic signs of opioid withdrawal. Specifically, inhibition the enzyme fatty acid amide hydrolase (FAAH), the catabolic enzyme for the endocannabinoid …
