The effects of corticosterone on persistence of attention in Mus musculus
Thesis
(1987). The effects of corticosterone on persistence of attention in Mus musculus

It is widely believed that corticosterone plays a role in psychological, and ultimately behavioural adaptation during stress. The aim of this thesis was to examine the nature of the adaptation brought about by corticosterone. The hypothesis under tes...

An investigation of the structure of tumour necrosis factor a in Cyprinus carpio
Thesis
(2017). An investigation of the structure of tumour necrosis factor a in Cyprinus carpio

Tumour necrosis factor a (TNF-a) is a soluble cytokine that has a number of different roles in the immune system. It carries out these functions by binding to one of its receptors TNF receptor 1 (TNFR1) and TNF receptor 2 (TNFR2). Cyprinus carpio (co...

Soluble crosslinked hydroxypropyl(methacrylamide) copolymers have been studied in the rat, both in vitro and in vivo, in order to assess their suitability as drug carriers in a targetable drug delivery system. The lO radiolabelled copolymers used w... Read More about Evaluation of crosslinked soluble N-(2-Hydroxypropyl) Methacrylamide copolymers as a potential drug carrier.

Prenatal maternal stress in Mus musculus: effects on the offspring, and the role of the mother
Thesis
Creighton, J. A. (1985). Prenatal maternal stress in Mus musculus: effects on the offspring, and the role of the mother

The aim of this project was to examine certain aspects of prenatal stress, by providing a more comprehensive study of one strain of animal in one laboratory than hitherto presented. The stressor employed was that of crowding during the last third of... Read More about Prenatal maternal stress in Mus musculus: effects on the offspring, and the role of the mother.

Thesis
Gravano, S. (1985). An experimental study of fine-grain motion perception in the human visual system

This thesis explores the characteristics of motion perception in the peripheral field of the human visual system as revealed by the fine-grain movement illusion, in which the sequential flashing of two spatially unresolved dot flashes results in the...

Directional and orientational tuning in the striate cortex of the cat for contrast and textured stimuli
Thesis
Tigwell, D. A. (1985). Directional and orientational tuning in the striate cortex of the cat for contrast and textured stimuli

1. Striate cortical neurones respond selectively to the orientation of moving contrast bars. The mechanism for that selectivity has alternatively been attributed to the geniculo-cortleal synapse or Inhibitory intracortical circuitry. Functionally, t...

Studies in parasitology: application for the award of the degree of Doctor of Science
Thesis
Arme, C. (1986). Studies in parasitology: application for the award of the degree of Doctor of Science

Preface Analysis of the interactions that occur between parasites and their hosts is complicated by the fact that the environment of an endoparasite is another living organism. A frequent starting point for such analyses is the study of isolated hos... Read More about Studies in parasitology: application for the award of the degree of Doctor of Science.
