Gene therapy is a therapeutic approach to deliver genetic material into cells to alter their function in entire organism. One promising form of gene delivery system (DDS) is liposomes. The success of liposome-mediated gene delivery is a multifactorial issue and well-designed liposomal systems might lead to optimized gene transfection particularly in vivo. Liposomal gene delivery systems face di...

We develop a multi-country Dixit-Stiglitz model to investigate the impacts of: (i) changes in the international distribution of consumers’ expenditure; (ii) decreasing tariffs; and (iii) improvements in transportation infrastructure. We show that, in general, decreasing tariff barriers do not allow for any clear predictions regarding changes in industry location and welfare, whereas this is pos...

BACKGROUND Minority vulnerable communities, such as the European Roma, often face numerous barriers to accessing healthcare services, resulting in negative health outcomes. Both these barriers and outcomes have been reported extensively in the literature. However, reports on barriers faced by European non-Roma native communities are limited. The "Health Care Access Barriers" (HCAB) model identi...

RESEARCH DESIGN AND METHODS A total of 323 participants (35.6% European, 32.2% Maori, and 32.2% Pacific Islander) from the South Auckland Diabetes Project (free of major complications by self-re...

Our research group has been investigating various aspects of graphics recognition techniques for more than ten years. We have worked on map analysis, symbol recognition, dimension analysis and the conversion of engineering drawings to CAD models. Lately, we are also conducting research on the interpretation of architectural drawings. In addition, we have built up a software platform of generic ...
