CD95/Fas is a cell surface protein that belongs to the tumor necrosis factor receptor family. Signals through CD95/Fas are able to induce apoptosis in sensitive cells. Therefore, modalities to regulate the CD95/Fas expression level in tumor cells are called for. In the present study, we show that sublethal doses of arsenic trioxide (As2O3) sensitized(More)
BACKGROUND Diabetes education and lifestyle modification are critical components in controlling blood glucose levels of people with type 2 diabetes. Until now, available data on the effectiveness of education with respect to the duration of diabetes are limited. We investigated whether adherence to lifestyle behavior modification prompted by diabetes(More)
Heart rate (HR) was measured continuously while men (n=6) and women (n=2) ages 71 to 85 years (M=77.4, SD=4.1) completed nine gardening tasks. HR and VO2 from a submaximal graded exercise test were used to estimate gardening VO2, energy expenditure, % HRmax, and metabolic equivalents (METs). Tasks were low to moderate intensity physical activity (1.6-3.6(More)
Light-emitting diodes (LEDs) can be used in closed-type plant production systems as an artificial light source. Here, we determined the effects of monochromatic LEDs on the growth and production of phenolic antioxidants in cherry tomato seedlings (Solanum lycopersicum L. ‘Cuty’). Two week-old seedlings germinated under normal growing conditions were(More)
Iron (Fe) is an essential micronutrient involved in fundamental biological processes in both humans and plants. Iron deficiency is common in humans, making iron supplementation of foods an important area of research. Edible sprouts are a rich source of minerals and phenolic compounds beneficial to human health; our objective was therefore to investigate the(More)
Iron (Fe) is essential for many vital processes in plants, including chlorophyll biosynthesis, DNA synthesis, nitrogen reduction, and photosynthetic electron transfer. However, free Fe ions also participate in the Fenton reaction, which generates reactive oxygen species that induce oxidative stress, leading to lipid peroxidation, protein oxidation, and DNA(More)
While the flower market has traditionally placed emphasis on the external quality (appearance) of cut flowers, the internal quality (longevity) has become increasingly important for retail marketing and consumers. In this study, we investigated key factors affecting the vase life of cut roses via multiple regression analysis (MRA) and examined the use of(More)
