Cognitive and neural mechanisms of social motivation / by Katherine E. Powers.
The need for social connection is a pervasive and powerful human drive. When this fundamental need is not fulfilled, people place greater emphasis on forming social bonds and are motivated to behave in ways consistent with accomplishing these...

The flight behavior and dispersal ecology of the red milkweed beetle, Tetraopes tetraopthalmus
Red milkweed beetle. Insects -- Flight. Insects -- Dispersal.
Most detailed studies of insect flight and dispersal have used long flying species as subjects. Little is known of the flight ecology of comparatively short flying species. This thesis reports the findings of a 4 year study of the flight behavior...

Characterization of the interaction of the chemotherapeutic drug mitomycin C with DNA in vitro and in vivo and effects on specific DNA-protein interactions.
Mitomycin C -- Mechanism of action. ; DNA -- Effect of mitomycin C on. ; Genetic expression -- Effect of mitomycin C on. ; DNA-protein interactions -- Effect of mitomycin C on.
Mitomycin C (MMC) is a chemotherapeutic drug that reacts with the N$\sp2$ of guanine to form monoadducts, interstrand and intrastrand crosslinks. These lesions, especially the interstrand crosslink, are believed to be responsible for the potent...

Characterization of catalase in Arabidopsis thaliana.
Arabidopsis thaliana -- Genetics.
The Arabidopsis catalase gene family contains at least three genes, encoding subunits which combine in tetramers to form 7 detectable isozymes. Two of these genes are within 250 bp of each other at a single locus (CAT3/1) near the top of chromosome...

The biophysical characterization of the interaction of XPA and the minimal DNA binding domain, XPA-MF122, with a mitomycin C-DNA interstrand crosslink.
Mitomycin C -- Mechanism of action. ; Xeroderma pigmentosum. ; DNA -- Effect of mitomycin C on. ; DNA-protein interactions -- Effect of mitomycin C on. ; DNA repair. ; Arsenic -- Physiological effect. ; Cadmium -- Physiological effect.
Despite the fact that numerous chemically and structurally diverse DNA lesions are repaired by nucleotide excision repair (NER), the mechanism of the interaction of XPA with damaged DNA is not well characterized. The overall goal of this study was...

Cytokinin and the transcriptional regulation of chloroplast development in Arabidopsis.
Chloroplasts -- Formation. ; Genetic transcription -- Regulation. ; Transcription factors. ; Arabidopsis -- Genetics. ; Arabidopsis proteins. ; Cytokinins.
Cytokinins regulate broad aspects of plant growth and development, such as cell division, root and shoot growth, chloroplast development, and leaf senescence. Cytokinins are perceived by a signal transduction pathway that involves receptors,...

Identification and role of protein-protein interactions in signaling by the ethylene receptors of Arabidopsis.
Protein-protein interactions. ; Ethylene -- Receptors. ; Cellular signal transduction. ; Arabidopsis -- Genetics.
There are five ethylene receptors (ETR1, ERS1, ETR2, ERS2, and EIN4) in Arabidopsis. In this study, I tested the hypothesis that ethylene receptors mediate ethylene signaling through protein-protein interactions. First, I demonstrated that ethylene...

Effects of mitomycin C and other DNA crosslinking agents on gene expression: modulation of cancer cell multidrug resistance in cell culture and in vivo.
Mitomycin C -- Genetic aspects. ; DNA damage. ; Drug resistance in cancer cells. ; Cancer -- Chemotherapy -- Genetic aspects.
Our laboratory is concerned whether the distribution of chemically-induced DNA damage is non-random at the level of individual genes. Using changes in gene expression as a marker for DNA damage, we have previously demonstrated that genotoxic...
