Apoptotic beta-cell death is central to the pathogenesis of type 1 diabetes and may be important in islet graft rejection. Despite this, genetic control of beta-cell apoptosis is only poorly understood. We report that inhibition of gene transcription sensitized beta-cells to tumor necrosis factor (TNF)-alpha-induced apoptosis, indicating the presence of a(More)
Inappropriate elevation of matrix metalloproteinase-9 (MMP9) is reported to be involved in the pathogenesis of chronic obstructive pulmonary disease (COPD). The object of this study was to identify the molecular mechanism underlying this increase of MMP9 expression, and here we show that oxidative stress-dependent reduction of a protein deacetylase, SIRT1,(More)
Both Melissa officinalis (Mo) and Lavandula angustifolia (La) essential oils have putative anti-agitation properties in humans, indicating common components with a depressant action in the central nervous system. A dual radioligand binding and electrophysiological study, focusing on a range of ligand-gated ion channels, was performed with a chemically(More)
BACKGROUND Accumulation of nitrated protein is seen in peripheral lung and cells from patients with chronic obstructive pulmonary disease (COPD). Nitrated protein causes abnormal protein function, but the nitration was believed to be an irreversible process. However, there are accumulating evidences that this process is reversible by an active denitration(More)
Patient record data are potentially highly sensitive and their secondary use raises both ethical and data protection issues. Disclosure of patient data could cause serious difficulties for the medical profession and be potentially damaging for individual patients and clinicians. Yet at the same time patient records are a hugely valuable resource in terms of(More)
Advances in data storage, data collection and inference techniques have enabled the creation of huge databases of personal information. Dissemination of information from such databases-even if formally anonymised, creates a serious threat to individual privacy through statistical disclosure. One of the key methods developed to limit statistical disclosure(More)
As genomic data becomes widely used, the problem of genomic data privacy becomes a hot interdisciplinary research topic among geneticists, bioinformaticians and security and privacy experts. Practical attacks have been identified on genomic data, and thus break the privacy expectations of individuals who contribute their genomic data to medical research, or(More)
