Ptprq, a receptor-like phosphatase known to be associated with the shaft connectors of stereocilia, is a protein required for the maintenance of the hair-bundle structure. The extracellular domain of Ptprq has numerous potential sites for N-glycosylation and the cytoplasmic doma…

Manganese peroxidase 3 (MnP3) is an extracellular peroxidase from the white-rot fungus, P. radiata that is a well-studied wood/lignin degrader from Scandinavian forest (Hilden et al., 2005). Unlike the Phanerochaete chrysosporium MnP's previously characterised, the P. radiata Mn…
The sensory hair bundles of the cochlea are complex structures that are vital for hearing. Phosphorylation plays an important role in regulating actin in many cell types, but the role it plays in regulating the development and maintenance of the hair bundle has yet to be fully e…
One of a synthetic organic chemists‟ greatest challenges is to create step-efficient routes toward compounds with high molecular complexity. Therefore, reactions such as the meta photocycloaddition of an olefin to a benzene derivative, which provide more than one bond in a singl…
DNA damage is chronic, inevitable and extensive. Damage caused by UV irradiation can cause bulky DNA lesions that block replication forks. Postreplication repair (PRR) is a DNA damage tolerance mechanism, which enables the replication machinery to bypass DNA lesions. The PRR mac…
A [5:5] ligand based on the bicyclic guanidine 1,4,6-triazabicyclo[3.3.0]oct-4-ene [Htbo] has been synthesised. Two of these tbo units have been linked via a carbon bridgehead to form a novel bidentate ligand. Based on the knowledge that the electronic properties and specific st…
Influenza virus infection and the shikimic acid pathway are two of many examples of microbe-host interactions and microbial biosynthetic pathways that are interesting for investigation by means of small molecules. A particularly interesting structural motif common to both is the…
Matrix assisted laser desorption/ionisation mass spectrometry (MALDI-MS) is a relatively new technique for imaging lipids directly in tissue, with useful applications in disease state profiling, bacterial typing and forensics. This thesis describes optimisation and evaluation of…
Recent studies have shown the numerous advantages associated with specific drug delivery to the colon, highlighting its favourable conditions and long transit time as the main advantages. A number of in vitro studies also show that the delivery of liposomes to the colon could pr…
Studies were conducted to explore whether high pressure (up to 700 MPa) could be used in combination with elevated temperatures (up to 90°C initial temperature) to produce ambient stable green beans (Phaseolus vulgaris) with improved quality compared with conventionally heat pro…
Dry powder inhaler (DPI) formulations are usually comprised of a mixture of micronised active pharmaceutical ingredient (API) with aerodynamic diameter 1-5 m to allow deposition in the lower airways, and a coarse (~70 micron) excipient, typically \(α\)-lactose monohydrate, used …
Industrial reactions can either be catalysed by acidic, basic or neutral supported catalysts. The work within this thesis includes two different projects of industrial interest, both of which are catalysed by basic and acidic supported catalysts. (1) Acrylonitrile is one of the …
Chapter One gives an overview of molecule-based magnetic materials, and a summary of topics of current interest in this field such as spin crossover (SCO), molecule-based magnets (particularly three room temperature metallo-organic magnets), Metallo-organic frameworks (MOFs), fr…
This thesis describes our attempts towards realising new chemistry involving methyleneaziridines, for the main part, focusing on novel cycloaddition reactions involving this unique, densely functionalised heterocycle. Contrary to methyleneaziridines, the cycloaddition reactions …
The contribution of store-operated calcium entry (SOCE) in the response of human sperm to progesterone, a steroid secreted from the cumulus cells surrounding the oocyte, has not yet been elucidated. The aim of this study was to investigate the presence of SOCE proteins in human …
The biaryl motif is found in many natural and synthetic products that display a wide range of biological activities. This explains why biphenyls are widely encountered in medicinal chemistry as a privileged scaffold. The palladium-catalysed Suzuki-Miyaura (SM) coupling is one of…
The ability to adapt to changing environments is essential for survival. Bacteria have developed sophisticated means by which they sense and respond to stresses imposed by changes in the environment. Escherichia coli (E. coli) have served as a model organism for studies in molec…
An ever increasing incidence of diabetes has resulted in an epidemic of chronic wounds. Few therapies effectively promote wound healing, and thus, health care budgets are faced with an unsustainable burden and patients with poor quality of life. Recently, the isoleucine-glycine-…
The aim of this thesis was to investigate crystal nucleation, growth and dissolution processes, focussing particularly on the behaviour of the crystal surface. To facilitate this various methods of microscopy were used, as well as electrochemical techniques, with the goal to sep…
