Photosynthetic antenna-reaction-center mimicry
… presented in this dissertation discusses the mimicry of primary events in natural photosynthesis via artificial molecular constructs. Photosynthesis involves two major steps, absorption of light by antenna pigments and transfer of the excitation energy to the reaction center where charge …

Predicting motif mimicry in viruses
… PPI data can be used to study molecular mimicry in viruses and to discover novel SLiMs. An in-silico peptide exchange approach was developed and applied to provide additional validation of predicted mimicry candidates. Despite limitations of this technique in large-scale validation of …

Targeting Vasculogenic Mimicry in Cancer
… mechanism to angiogenesis known as vascular mimicry (VM). In VM capable tumours, pseudo blood vessels are formed by tumour cells that have acquired endothelial-like properties independently of host endothelium. VM is a marker of poor prognosis and metastasis in patients, however it is still …

Dynamics of salticid-ant mimicry systems
Mimicry in arthropods is seen as an example of evolution by natural selection through predation pressure. The aggressive nature of ants, and their possession of noxious chemicals, stings and strong mandibles make them unfavourable prey for many animals. The resemblance of a similar-sized arthropod …

Vocal mimicry in the brown thornbill
Mimicry of other species' alarm calls is common among birds, but its function is often unknown. Although anti-predator functions for mimetic alarm calls have been suggested, these are yet to be tested. In this thesis I formally evaluated claims of vocal mimicry in the brown thornbill (Acanthiza …

The evolution of exploitation through mimicry
The aim of this thesis is to propose that mimicry of signals in human communication is an effective behavioural strategy for exploiting social systems. Detection of mimicry may consequently have evolved as a counterstrategy, creating a competitive co-evolutionary relationship between signaller and …

Teaching linguistic mimicry to improve second language pronunciation.
… suprasegementals through the use of linguistic mimicry is more effective than a focus on segmentals in improving native speakers perceptions of accent and comprehensibility of ESL students' pronunciation of English. The thesis is organized into seven chapters. Chapter 2 is a discussion of the …

Biodiversity, conservation and mimicry rings of Appalachian millipedes
… and hue, are shared between genera in aposematic mimicry rings. Leading to the formation of mimicry rings between distantly related genera, their bright coloration functions to advertise a cyanide-based defense. Some species have been recorded as having six color patterns, each a member of a …

Nonconscious mimicry and its effect on rapport and recall
Nonconscious mimicry is used to build rapport as well gain the liking of others, during first encounters and when there is a perceived threat to belonging or existing relationships. Mimicry can occur through verbal and nonverbal methods such as physical gestures, mannerisms and taking on the …

Mimicry and speciation in the parasitic finches of Africa
… by critically examining the logic with which mimicry in the natural world can be conceptually organized (Chapter 2). This creates a “mimicry landscape” in which to situate the mimetic adaptations of hosts exhibited by Vidua. The framework can be used to contrast and draw parallels between …

Molecular characterization of CLE peptide mimicry during cyst nematode pathogenesis
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT AUTHOR'S REQUEST.] Plant-parasitic cyst nematodes establish intimate parasitic relationships with their hosts by penetrating the root as motile juveniles and migrating intracellularly until they reach the root vasculature where they …

Eukaryotic protein mimicry as an infection strategy for Ehrlichia chaffeensis
… document reports the first example of bacterial mimicry of Wnt pathway ligands and investigates a pathogenic mechanism with potential for targeting by antimicrobial therapeutics.

Prenatal Testosterone, Empathy, Emotion Recognition, and Facial Mimicry in Women
… whether individual differences in facial mimicry, emotion recognition, and empathy are related to prenatal testosterone (PT) exposure. Previous studies have found relationships among facial mimicry, emotion recognition, and selfreport empathy scores; further, imaging studies suggest that …

Toward Hydrogenase mimicry : subjecting the problem to three different approaches
In this work, the challenging task of modelling Hydrogenase is subjected to three different approaches. The first strategy used here is bioorganometallic. A wide range of sulfur containing ferrocene-peptide derivatives were synthesized and fully characterized. As a second approach, organic …
