OBJECTIVE Evidence from pivotal clinical trials conducted more than a decade ago supports the use of antithrombotic therapy, particularly warfarin, for stroke prevention in atrial fibrillation (AF). Despite the wide dissemination of this evidence since that time, there is anecdotal evidence that utilisation of therapy remains suboptimal, especially in the(More)
BACKGROUND & OBJECTIVE A-463 bp G/A polymorphism is located in the promoter region of myeloperoxidase (MPO) gene was found to be associated with lung cancer susceptibility; however, this association in Chinese population remained unclear. The aim of this study was designed to explore this association in Chinese population. METHODS MPO genotypes in 98(More)
Enterprise cloud tenants would store their outsourced cloud data in encrypted form for data privacy and security. However, flexible data access functions such as data searching is usually sacrificed as a result. Thus, enterprise tenants demand secure data retrieval and computation solution from the cloud provider, which will allow them to utilize cloud(More)
Private database query (PDQ) processing has received much attention from the fields of both cryptography and databases. While previous approaches to design PDQ protocols exploit several cryptographic tools concurrently, recently the appearance of fully homomorphic encryp-tion (FHE) schemes enables us to design PDQ protocols without the aid of additional(More)

This paper proposes an enhanced privacypreserving data aggregation scheme, which balances the onerous task of extracting reasonable data value and preserving data privacy even with incomplete or malicious data presentence. We propose an innovative encryption algorithm to preserve data privacy while it can provide secure data comparison between the encrypted(More)
Animal models and clinical studies suggest a mechanistic link between the pneumococcal polysaccharide vaccine (PPV) and a cardiovascular protective effect. However, conflicting results exist from several large observational studies in humans. We set out to systematically review current literature and conduct meta-analyses of studies on PPV and(More)
Data aggregation is generally used to reduce data streams and save energy consumption in cluster-based wireless sensor networks (CWSNs). However the vulnerable deployment environment of CWSN challenge the data aggregation in terms of data privacy and resiliency. If a node or a group of nodes are compromised or the sensing environment is manipulated by an(More)
