Radio frequency identification (RFID) uses radio frequency signals to automatically identify objects. RFID is used to pay for gas without going into the store, in automobile immobilizer systems to prevent theft, in toll road systems to automatically pay tolls without stopping, in animal identification, in secure entry cards, and in the supply chain to manage the flow of pallets, cases, and item...

Endothelial progenitor cells (EPCs) contribute to postnatal neovascularization. Risk factors for coronary artery disease reduce the number of EPCs in humans. Since EPC apoptosis might be a potential mechanism to regulate the number of EPCs, we investigated the effects of oxidative stress and HMG-CoA-reductase inhibitors (statins) on EPC apoptosis. Atorvastatin, mevastatin, or VEGF prevented EPC...

CHANGES IN VASCULAR MORPHOLOGY and function with increasing age clearly are significant contributors to age-related increases in cardiovascular disease (CVD). In addition, the presence of CVD risk factors, such as hypertension, hyperlipidemia, diabetes, and smoking, have been shown to cause endothelial dysfunction, an early marker of atherosclerosis and CVD. Regular physical activity is not onl...

RATIONALE Endothelial progenitor cell (EPC) survival and function in the injured myocardium is adversely influenced by hostile microenvironment such as ischemia, hypoxia, and inflammatory response, thereby compromising full benefits of EPC-mediated myocardial repair. OBJECTIVE We hypothesized that interleukin-10 (IL-10) modulates EPC biology leading to enhanced survival and function after tra...

AIMS Circulating endothelial progenitor cells (EPC), involved in endothelial regeneration, neovascularisation, and determination of prognosis in cardiovascular disease can be characterised with functional assays or using immunofluorescence and flow cytometry. Combinations of markers, including CD34+KDR+ or CD133+KDR+, are used. This approach, however may not consider all characteristics of EPC....

Two cationic phospholipid derivatives with asymmetric hydrocarbon chains were synthesized: ethyl esters of oleoyldecanoyl-ethylphosphatidylcholine (C18:1/C10-EPC) and stearoyldecanoyl-ethylphosphatidylcholine (C18:0/C10-EPC). The former was 50 times more effective as a DNA transfection agent (human umbilical artery endothelial cells) than the latter, despite their similar chemical structure and...

Stable enzyme precipitate coatings (EPCs) with high enzyme loading were employed to develop a sensitive and reliable detection protocol, termed EPC-linked aptamer assay (EPC-LAA). EPC-LAA achieved the limit of detection to be 0.5 ng per mL of thrombin (13.5 pM), and maintained a reasonably stable detection signal even after storing all the reagents at 40 °C for 66 days.
