Ursolic acid and related pentacyclic triterpenoids have been isolated and identified as constituents of various berries, particularly cranberries (Vaccinium macrocarpon) and other Vaccinium species. In vitro studies have shown that these compounds possess anti-inflammatory and anti-cancer activities. These compounds reportedly inhibit the growth of numerous tumor cell lines including colon, bre...

Antibacterial activity, total phenolic content and flavonoid concentrations of extracts from the leaves of Arctostaphylos uva-ursi L. were performed. Tested bacterial strains are 20 clinical isolates, including different strains of Escherichia coli and Enterococcus faecalis. The total phenolic content was determined using Folin-Ciocalteu reagent. The concentration of flavonoids in extracts were...

Lack of association between the prothrombin rs1799963 polymorphism and juvenile myoclonic epilepsy Ausência de associação entre o polimorfismo G20210A (rs1799963) da protrombina e epilepsia mioclônica juvenil João Paulo Lopes Born1, Bruna Priscila dos Santos1, Rodrigo Secolin2, Fernando Tenório Gameleira3, Tiago Gomes de Andrade3, Luciana Cláudia Herculano Machado4, Lívia Leite Góes Gitaí5, Dan...

The article explores to what extent historical archives at museums may serve as documental sources in developing audience research. It analyzes the process by which we construct our knowledge of the relation between museums and their different visitors and also contextualizes the emergence of 'audience' as a category and object of study by the social sciences. The article presents Luciana Sepúl...

Although most biological invasions are not successful, relatively few studies have examined otherwise notorious invaders in systems where they are not highly problematic. The annual grass Bromus tectorum is a dominant invader in western North America, but is usually confined to human-dominated and disturbed systems (e.g. roadsides and parking lots) in the East where it remains virtually unstudi...

As a result of climate change, many plants are now flowering measurably earlier than they did in the past. However, some species' flowering times have changed much more than others. Data at the community level can clarify the variation in flowering responses to climate change. In order to determine how North American species' flowering times respond to climate, we analyzed a series of previousl...

Vaccinium uliginosum L. (commonly known as bog bilberry) and myrtillus are species of the genus (family Ericaceae). The red–purple–blue coloration blueberries is attributed largely to anthocyanins found in bilberries. Anthocyanins, for their potent biological activity antioxidants, have a significant involvement prophylaxis cancer or other diseases, including those metabolic origin. Bilberry mo...
