Today image steganography plays a key role for exchanging a secret data through the internet. However, the optimal choice of images formats for processing steganography is still an open issue; therefore, this research comes into a table. This research conducts a comparative study between Scalable Vector Graphics (SVG) image format and Portable Network Graphics (PNG) image format. As results sho...

BACKGROUND The pattern of saphenous vein graft (SVG) calcification before percutaneous intervention has not been studied. METHODS AND RESULTS We used diagnostic and preintervention intravascular ultrasound (IVUS) to determine the incidence and magnitude of SVG calcification in 334 SVG lesions in 274 consecutive patients. Calcium was found in 133 SVGs (40%). Calcium was uniformly distributed a...

OBJECTIVE Stent implantation into atherosclerotic coronary vessels impacts on downstream microvascular function and induces the release of particulate debris and soluble substances, which differs qualitatively and quantitatively between native right coronary arteries (RCAs) and saphenous vein grafts on right coronary arteries (SVG-RCAs). We have now quantified the release of microparticles (MPs...

UNLABELLED The human fetal glial cell line SVG was generated in 1985 by transfecting primary fetal brain cells with a plasmid containing an origin-defective mutant of simian virus 40 (SV40). The cells, which express SV40 large T-antigen, support the replication of human JC polyomavirus (JCPyV) and have been used for JCPyV studies but also for other studies in which cells of neural origin were d...

Office sonovaginography (SVG) challenges the concept of the "normal" pelvic ultrasound in women with chronic pelvic pain and suspected endometriosis. When positive for posterior compartment deep infiltrating endometriosis, with or without Pouch of Douglas obliteration, office SVG allows for triaging of women to the appropriately trained advanced laparoscopic gynaecological and colorectal surgic...

Abstract Background A long segment stricture in the anterior urethra is a challenge urology. We conducted study to investigate efficacy of urethral reconstruction using an everted saphenous vein graft (SVG) tubular fashion. Methods Twelve male beagles were randomly divided into three groups: experimental group (n = 5), control 5) and normal 2). 3 cm defect was created. Autologous SVG harvested....

Stent implantation into atherosclerotic coronary arteries releases particulate debris and soluble substances that contribute to impaired microvascular perfusion. Here we addressed the potential for microvascular obstruction in patients with stenotic native right coronary arteries (nRCA) compared with saphenous vein grafts on right coronary arteries (SVG-RCA). We enrolled symptomatic, male patie...

BACKGROUND Saphenous vein graft (SVG) disease is the major determinant of long term graft viability in patients undergoing coronary artery bypass graft (CABG) surgery. Although, platelets play a major role in this pathogenetic process the nature of this interaction has not been yet been clarified. Mean platelet volume (MPV) reflects platelet production rate and stimulation. This study was desig...

PURPOSE To compare the cytotoxic effect of TA on human retinal pigment epithelium (ARPE19) and human glial (SVG) cells over a range of concentrations and durations of exposure. METHODS TA (0.01-1 mg/mL) or vehicle (benzyl alcohol, 0.025%) was added to the ARPE19 and SVG cultures on day 0 and then subsequently for 1, 3, or 5 days. The amount of cell proliferations with or without TA treatment ...
