We formulate and describe a visual compactification of the Teichmüller space by Weil-Petersson geodesic rays emanating from a point X. We focus on analogies with Bers’s compactification: due to non-completeness, finite rays correspond to cusps, and such cusps are dense in the visual sphere. By analogy with a result of Kerckhoff and Thurston, we show the natural action of the mapping class group...

Zizyphus spina-christi (ZSC) fruit is a rich source of bioactive compounds but any medicinal properties in chemoprevention of colon cancer have hitherto not been studied. The aim of the present study was to examine in vivo protective effects of ZSC water extract on colon carcinogenesis in azoxymethane (AOM)-treated rats. Our results showed that ZSC significantly reduced AOM-induced colonic aber...

BACKGROUND Pemphigus foliaceus and pemphigus vulgaris are endemic in the northeastern region of São Paulo State, Brazil. They are treated mainly with systemic corticosteroids, which may provoke osteoporosis; atherosclerosis, higher blood pressure, insulin resistance, glucose intolerance, hyperlipidemia and abdominal obesity. These side effects of corticoids also constitute criteria for the diag...

BACKGROUND The study was designed to investigate the probable mechanisms of anti-hyperglycemic activity of B. Vulgaris. METHODOLOGY/PRINCIPAL FINDINGS Aqueous fraction of B. Vulgaris extract was the only active fraction (50mg/kg). Plasma insulin level was found to be the highest at 30 mins after B. Vulgaris administration at a dose of 200mg/kg. B. Vulgaris treated mice were also assayed for p...

introduction: south khorasan province is the main area for production of berberis vulgaris (family), crocus sativus (family) and ziziphus zizyphus (family). nematodes belong to superfamily aphelenchoidea are easy to be identified by the size of the body, stylet without knobs, large median bulb, long overlapping on the intestine and placement of the vulva in the posterior part of body. in this s...

BACKGROUND Ziziphus Mill. (jujube), the most valued genus of Rhamnaceae, comprises of a number of economically and ecologically important species such as Z. jujuba Mill., Z. acidojujuba Cheng et Liu and Z. mauritiana Lam. Single nucleotide polymorphism (SNP) markers and a high-density genetic map are of great benefit to the improvement of the crop, mapping quantitative trait loci (QTL) and anal...

one pollutant which seriously threatens water resources is dye. therefore, finding a suitable method to separate the dye in water resources is very important. an adsorption process that uses low cost adsorbents is considered as an efficient strategy for this purpose. in this study, erythrosine dye removal from an aquatic environment using natural absorbents, namely sorghum and ziziphus nummular...

Under the influence of the Western Iberian upwelling system, the Iberian Atlantic coast holds important hatcheries and recruitment areas for Octopus vulgaris. Recently identified as an octopus hatchery, the Ría de Vigo harbors an important mesozooplankton community that supports O. vulgaris paralarvae during the first days of their planktonic stage. This study represents a preliminary approach ...

The toxic effects of ethyl cinnamate on the photosynthetic and physiological characteristics of Chlorella vulgaris were studied based on chlorophyll fluorescence and flow cytometry analysis. Parameters, including biomass, F(v)/F(m) (maximal photochemical efficiency of PSII), Ф(PSII) (actual photochemical efficiency of PSII in the light), FDA, and PI staining fluorescence, were measured. The res...
