Coexisted peripheral vascular disease (PVD: ankle/brachial pressure index A/PBI less than 0.75) or carotid artery disease (CTD: Brochenbrough's supraorbital Doppler flow analysis) were diagnosed by non-invasive testings, and correlated with clinical pictures and coronary backgrounds in 121 consecutive patients with confirmed coronary artery disease. PVD were found in 16.5%, CTD in 33.1% and bot...

Under iron-limiting conditions, Pseudomonas aeruginosa PAO1 secretes a fluorescent siderophore called pyoverdine (Pvd). After chelating iron, this ferric siderophore is transported back into the cells via the outer membrane receptor FpvA. The Pvd-dependent iron uptake pathway requires several essential genes involved in both the synthesis of Pvd and the uptake of ferric Pvd inside the cell. A p...

The prevalence of peripheral vascular disease (PVD) was determined in 296 Japanese diabetics (mean age 55.2 years, range 19 to 79 years), using a Doppler ultrasonic technique. PVD was diagnosed in 11.5% of the diabetic patients (7.6% females, 14.6% males). In 88% of all patients with PVD, asymptomatic impaired circulation was diagnosed. There was a clear increase of PVD with age. It was found t...

PURPOSE To determine prevalence and associations of incomplete posterior vitreous detachment (PVD). METHODS The population-based cross-sectional Beijing Eye Study 2011 included 3468 individuals with a mean age of 64.6±9.8 years (range: 50-93 years). A detailed ophthalmic examination was performed including spectral-domain optical coherence tomography (SD-OCT). Incomplete PVD was differentiate...

OBJECTIVE To determine the role of hyperglycemia in prospective analyses of peripheral vascular disease (PVD) in type 2 diabetes, taking into account other potential risk factors. RESEARCH DESIGN AND METHODS Potential risk factors for the development of PVD were examined in 3,834 of 5,102 individuals enrolled in the U.K. Prospective Diabetes Study (UKPDS) without PVD at diagnosis of diabetes,...

PURPOSE To show a case in which the shape of the fovea changed after an asymptomatic macular posterior vitreous detachment (PVD). METHODS The foveal shape was determined from the spectral-domain optical coherence tomography (OCT) images before and after a spontaneous macular PVD. RESULTS A 66-year-old man with a unilateral macular hole in the right eye presented with a perifoveal PVD in the...

The siderophore pyoverdine (PVD) is a primary virulence factor of the human pathogenic bacterium Pseudomonas aeruginosa, acting as both an iron carrier and a virulence-related signal molecule. By exploring a number of P. aeruginosa candidate systems for PVD secretion, we identified a tripartite ATP-binding cassette efflux transporter, here named PvdRT-OpmQ, which translocates PVD from the perip...

Pixel-value differencing (PVD) steganography generates step effects or abnormal high fluctuations in PVD histogram. Since steganalysis exploits these artifacts to defeat the PVD steganography, modified PVD (MPVD) steganography preserving the PVD histogram is recently presented. This paper proposes a novel steganalysis method, in which we embed message one more time into the suspicious image to ...

This study was designed to determine whether patients with peripheral vascular disease (PVD) have gait abnormalities. A previous study on humans with PVD found no abnormalities whereas significant gait changes were seen with a rat model of PVD. The study population was comprised of 10 controls and 9 subjects with PVD (all male). The PVD group had documented pain in one or both legs while walkin...

PURPOSE In this study, to optimize the polymeric drug delivery system for cancer chemotherapy, we developed a new pH-sensitive polymeric carrier, poly(vinylpyrrolidone-co-dimethylmaleic anhydride) [PVD], that could gradually release native form of drugs with full activity, from the conjugates in response to changes in pH. We examined the usefulness of PVD as a polymeric drug carrier. EXPERIME...
