In this paper, we argue that future systems need to be designed using a flexible user-centric design methodology geared primarily toward maximizing the user satisfaction (<i>i.e., flow experience</i>) rather than seeking mainly optimization of performance and power consumption. Compared to the traditional design, we aim at re-focusing the current design(More)
Three studies test whether group members strategically shift the standard of judgment they use to decide whether a particular ingroup action was unjust. In Study 1, individuals who were highly identified with their ingroup set higher confirmatory injustice standards than low identifiers-they needed more evidence to conclude that their group acted unjustly.(More)
The chemical constituents and biological activity of Pinus cembra L. (Pinaceae), native to the Central European Alps and the Carpathian Mountains, are not well known. The aim of the present work was to examine the phenolic content, antioxidant and antimicrobial effects of hydromethanolic extracts of Pinus cembra L. bark and needles. Bark extract had higher(More)
The aim of this study is to characterize the content of Aronia melanocarpa Elliott (black chokeberry) extract and also to estimate the influence of polyphenolic compounds contained in chokeberries on oxidative stress, on an L-NAME-induced experimental model of arterial hypertension. The rat blood pressure values were recorded using a CODA Noninvasive Blood(More)
Various phytochemicals, mainly phenolic derivatives, have been screened for their radioprotective properties. This review summarizes the current knowledge in radioprotection using plant bioactive compounds with emphasis on two promising compounds, curcumin and genistein. Free radical scavenging abilities, maintaining cellular antioxidant status, modulation(More)
Spirulina is a species of filamentous cyanobacteria that has long been used as a food supplement. In particular, Spirulina platensis and Spirulina maxima are the most important. Thanks to a high protein and vitamin content, Spirulina is used as a nutraceutical food supplement, although its other potential health benefits have attracted much attention.(More)
Human exposure to genotoxic agents has dramatically increased. Both endogenous (reactive species generated during physiological and pathological processes) and exogenous (UV light, ionizing radiation, alkylating agents, antimetabolites and topoisomerase inhibitors, air, water and food pollutants) factors can impair genomic stability. The cumulative DNA(More)
Sesquiterpene lactones are a large group of natural compounds, found primarily in plants of Asteraceae family, with over 5000 structures reported to date. Within this family, genus Artemisia is very well represented, having approximately 500 species characterized by the presence of eudesmanolides and guaianolides, especially highly oxygenated ones, and(More)
Gram-negative bacteria cause infections that are difficult to treat due to the emergence of multidrug resistance. This review summarizes the current status of the studies investigating the capacity of essential oils and their components to modulate antibiotic activity against Gram-negative bacteria. Synergistic interactions are particularly discussed with(More)
The roots of Vernonia kotschyana Sch. Bip. ex Walp. (Asteraceae) are used in Malian traditional medicine in the treatment of gastroduodenal ulcers and gastritis. Since oxidative stress is involved in gastric ulceration, the aim of this study was to screen the root extracts for their in vitro antioxidant activity and phenolic content. The roots were(More)
