In this paper, we shall propose a new image steganographic scheme for embedding secret messages into a gray-valued cover image and capable of producing a secret-embedded image that is totally indistinguishable from the original image by the human eye. In addition, the proposed scheme avoids the falling-off-boundary problem by using the Pixel-Value Differencing (PVD) and the Exploiting Modificat...

A number of nutrients are known to be effective in preventing cardiovascular disease (CVD). We investigated the possible effects of a daily intake of low amounts of these nutrients on risk factors and clinical parameters in patients with peripheral vascular disease and intermittent claudication (PVD-IC). Male PVD-IC patients (n = 60) were randomly allocated into 2 groups. The supplement (S) gro...

We continue to be both amazed and intrigued by the hype showered on cardiac CT angiography and the corresponding lack of hype given to peripheral vascular CTA. No doubt, 64-slice cardiac or coronary CTA is potentially a revolutionizing technology, but PV-CTA has already revolutionized the comprehensive diagnosis and treatment of peripheral vascular disease. This cardiac CTA infatuation should c...

Objective: Brain β-amyloid(Aβ) burden is one of the most important pathophysiological markers of Alzheimer diseases(AD). It is also important to note geriatric depression(GD) is associated with developing AD. But, there are few studies that have examined cortical Aβ levels in GD. The purpose of this study is exploring relationship between brain amyloid deposition and cognitive function in GD Me...

In response to iron limitation, Pseudomonas aeruginosa produces the fluorescent siderophore pyoverdine. Transcription of pyoverdine biosynthetic (pvd) genes is driven by the iron starvation sigma factor PvdS, which is negatively regulated by the Fur-Fe(II) holorepressor. We studied the effect of AlgQ, the Escherichia coli Rsd orthologue, on pyoverdine production by P. aeruginosa PAO1. AlgQ is a...

PURPOSE To evaluate vitreomacular relations in different stages of age-related macular degeneration (AMD) without the influence of genetics and environmental factors. DESIGN Retrospective, observational case series. METHODS This was a multicenter study consisting of 29 previously untreated subjects with active exudative (wet) AMD in one eye and active nonexudative (dry) AMD in the fellow ey...

We present the first determination of the pairwise velocity dispersion (PVD) for galaxies in different luminosity intervals using the final release of the TwoDegree Field Galaxy Redshift Survey (2dFGRS). We have discovered quite surprisingly that the relative velocities of the faint galaxies at small separation are very high, around 700 km s, reaching similar values as the brightest galaxies. A...
