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...

Mean platelet volume (MPV) is an indicator of platelet activation that is elevated in patients with coronary artery ectasia (CAE). We aimed to research relationship between MPV and the severity of coronary ectasia. The reports of 6,377 patients who underwent elective coronary angiography screening between January 2011 and January 2015 were reviewed. After exclusion, 117 patients with isolated C...

Coffea arabica extract (CAE) containing 48.3 ± 0.4 mg/g of chlorogenic acid and a trace amount of caffeic acid was found to alleviate photoaging activity in human skin fibroblasts. In this study, polyphenol-rich CAE was investigated for its antioxidant and antiinflammatory properties, as well as for its capability to alleviate ultraviolet B (UVB)-induced photodamage in BALB/c hairless mice. The...

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...

This study investigates the in vivo dose response profiles of the target enzyme cholinesterase (ChE) and the detoxifying enzymes carboxylesterase (CaE) in the fetal and maternal compartments of pregnant rats dosed with chlorpyrifos [(O,O'-diethyl O-3,5,6-trichloro-2-pyridyl) phosphorothionate], a commonly used organophosphorus insecticide. Pregnant rats were dosed daily (po) with chlorpyrifos i...

BACKGROUND Coronary artery ectasia (CAE) is defined as localized or diffuse dilation of the coronary arteries. There are scarce data about the role of dendritic cells in CAE development. In this study we investigated the activation markers on the surface of monocyte-derived dendritic cells (mDCs) in coronary artery disease (CAD) patients with or without CAE. METHOD The study consisted of 6 pa...
