Disease relevance of Yucca

• Four replicates of 10 broiler chicks (average body weight, 48 g) each were assigned to a control or diets containing 0.1% chloroxytetracycline (antibiotic), 0.1% Lactobacillus casei (probiotic), or 0.2% yucca extract [1].

High impact information on Yucca

• Here we report the characterization of a dominant Arabidopsis mutant, yucca, which contains elevated levels of free auxin [2].
• We found that SUPER1 encodes YUCCA5, a novel member of the YUCCA family of flavin monooxygenases [3].
• These results indicate that the anti-inflammatory properties attributed to Yucca schidigera can be ascribed to both resveratrol and Yuccaols and provide the first evidences of the anti-tumor and anti-invasive properties of these novel phenolic compounds [4].
• Colloid mobility was determined in a system consisting of quartz sand or crushed Yucca Mountain tuff, simulated groundwater (J-13), and hydrophilic latex particles [5].
• Water content (theta) and ionic strength (I; DI water, 0.1x, 1x, 10x groundwater dilution) were manipulated to define limiting conditions for colloid transport atthe Yucca Mountain site [5].

Biological context of Yucca

• The standards and regulations for the proposed Yucca Mountain high level radioactive waste repository, which were developed and promulgated by the U.S. Environmental Protection Agency and the U.S. Nuclear Regulatory Commission, respectively, are complex and challenging [6].

Anatomical context of Yucca

• Reaction product deposition attributable to catalase, glycolate oxidase, and urate oxidase activities are cytochemically localized to Yucca root microbodies and classifies them as unspecialized peroxisomes on the basis of their enzyme complement and tissue origin [7].
• A 6-wk study was conducted to determine the effect of feeding diets containing an antibiotic, a probiotic, or yucca extract on daily gain, feed conversion ratio, and urease activity and ammonia production in intestinal contents of broiler chicks [1].
• Effect of different dietary levels of Yucca schidigera powder on the performance, blood parameters and egg yolk cholesterol of laying quails [8].

Associations of Yucca with chemical compounds

• Microcosms were constructed by placing pulverized Yucca Mountain rock in polystyrene cylinders [9].
• A hitherto undescribed ballistosporous yeast was isolated from a dead leaf of Yucca sp. in Canada. This yeast produces apiculate or short-ellipsoidal ballistospores, produces pale colored colonies, has Q-9 as the major ubiquinone, and does not contain xylose in the cells [10].
• Although aerial ammonia concentrations were relatively low, the addition of Yucca schidigera extract or calcium chloride to the diet of nursery pigs reduced ammonia concentrations in the nursery rooms [11].
• The US Geological Survey (USGS) has documented hydrogenic calcite abundances in fractures and lithophysal cavities at Yucca Mountain to provide constraints on percolation fluxes in the UZ [12].
• In Trial 1, urea at 0 or 1% of the diet and yucca extract at 0 or 4 g/d formed four dietary treatments in a 2 x 2 factorial arrangement [13].

• Yucca schidigera bark: phenolic constituents and antioxidant activity [15].
• Uncertainties in coupled thermal-hydrological processes associated with the Drift Scale Test at Yucca Mountain, Nevada [16].
• A saponin fraction of Yucca extract was prepared by column chromatography with porous polymer, and hydrolyzed with a 2 mol/L mixture of hydrochloric acid-ethanol (1 + 1) to generate sapogenin [17].
• In a previous paper we have found as the main constituents of yucca bark, yuccaol A, B and C, new and very unusual spiro-derivatives made up of a C15 unit and a stilbenic portion closely related to resveratrol [18].
