BACKGROUND AND AIM Overexpression of matrix metalloproteinase (MMP)-1, -3, -7, -9, and plasminogen activator inhibitor-1 (PAI-1) are implicated in the invasion and metastasis of colorectal cancer, while MMP-12 provides a protective role against colorectal cancer. The promoter and exon polymorphisms of their genes, which are known to affect the transcription(More)
The expression of the nuclear vitamin D receptor (VDR), which is involved in regulating cell growth and proliferation, may contribute to the development of colorectal cancer. Polymorphisms in the VDR gene (OMIM 601769) may influence the expression or function of the VDR protein. A population-based, case-control study of VDR start codon, intron, and exon(More)
A group key agreement protocol is designed to efficiently implement secure mul-ticast channels for a group of parties communicating over an untrusted, open network by allowing them to agree on a common secret key. In the past decade many problems related to group key agreement have been tackled and solved (diminished if not solved), and recently some(More)
Although the etiology of Behçet's Disease (BD; MIM 109650) remains to be clearly elucidated, levels of tumor necrosis factor alpha (TNF-alpha) have been reported to be significantly elevated in BD patients, and TNF-alpha blockers have been demonstrated to exhibit some degree of therapeutic efficacy for a certain subset of BD sufferers. In this study, we(More)

Wireless sensor networks (WSNs) consist of sensors, gateways and users. Sensors are widely distributed to monitor various conditions, such as temperature, sound, speed and pressure but they have limited computational ability and energy. To reduce the resource use of sensors and enhance the security of WSNs, various user authentication protocols have been(More)
