We model oligomers of the Alzheimer's amyloid β-peptide Aβ(1-42) in an implicit membrane to obtain insight into the mechanism of amyloid toxicity. It has been suggested that Aβ oligomers are the toxic species, causing membrane disruption in neuronal cells due to pore formation. We use basin-hopping global optimization to identify the most stable structures(More)
Many bacterial pathogens naturally form cellular inclusions. Here the immunogenicity of polyhydroxyalkanoate (PHA) inclusions and their use as particulate vaccines delivering a range of host derived antigens was assessed. Our study showed that PHA inclusions of pathogenic Pseudomonas aeruginosa are immunogenic mediating a specific cell-mediated immune(More)
Tuberculosis (TB) is a disease caused by Mycobacterium tuberculosis or Mycobacterium bovis and still remains one of the world's biggest global health burdens. Recently, engineered polyhydroxyalkanoate (PHA) biobeads that were produced in both Escherichia coli and Lactococcus lactis and displayed mycobacterial antigens were found to induce significant(More)
In this paper, we present an enhanced virtual observation therapy (VOT) system to address challenges in medication adherence and the current observed therapy approach. The original approach requires both patient and healthcare worker to be physically collocated, which has several technical and practical challenges. Therefore, we developed a system that(More)
