The process of P release and transfer becomes more complex in environments strongly disturbed by human activities. In this paper, purple soils (about 37.8% of total soils) from areas with different sea level elevations and land use were sampled in the Water Fluctuation Zone (WFZ) in the Three Gorges Reservoir (TGR) along the Yangzi River. This research investigated the P distribution characteri...

We report a case of an elderly lady with a long-term suprapubic catheter who developed purple discoloration of urine around the same time as she developed intussusception. Purple urine bag syndrome is a benign condition known to be associated with intestinal stasis. However, this association with intussusception should be kept in mind before the patient is reassured.

Hibiscus syriacus is a highly ornamental flowering shrub widely grown in East Asia. Its abundant flower colors mainly reflect the accumulation of anthocyanins. Classifying H. petals and identifying relationship between color anthocyanins can provide references for breeding. With eight cultivars as experimental materials, floral was described using Royal Horticultural Society Color Chart CIEL*a*...

We study an algorithmic problem that is motivated by ink minimization for sparse set visualizations. Our input is a set of points in the plane which are either blue, red, or purple. Blue points belong exclusively to the blue set, red points belong exclusively to the red set, and purple points belong to both sets. A red-blue-purple spanning graph (RBP spanning graph) is a set of edges connecting...

The European rewardless, bee-pollinated orchid Dactylorhiza sambucina commonly produces yellow-flowered and purple-flowered individuals in frequencies that range from balanced (per population) to very unbalanced, with parts of the species’ range entirely monochromatic. We studied male and female reproductive success of the two morphs in 22 populations in the Czech Republic, relating it to morph...

Plant anthocyanin biosynthesis is well understood, but the regulatory mechanism in purple foliage tea remains unclear. Using isobaric tag for relative and absolute quantification (iTRAQ), 815 differential proteins were identified in the leaves of Zijuan tea, among which 20 were associated with the regulation of anthocyanin metabolism. We found that the abundances of anthocyanin synthesis-relate...

The extremely halophilic archaeon Halobacterium NRC-1 can switch from aerobic energy production (energy from organic compounds) to anaerobic phototrophy (energy from light) by induction of purple membrane biogenesis. The purple membrane is made up of multiple copies of a 1:1 complex of bacterioopsin (Bop) and retinal called bacteriorhodopsin that functions as a light-driven proton pump. A light...

We have developed a high-throughput T-DNA insertional mutagenesis program in tomato using activation tagging to identify genes that regulate metabolic pathways. One of the activation-tagged insertion lines (ant1) showed intense purple pigmentation from the very early stage of shoot formation in culture, reflecting activation of the biosynthetic pathway leading to anthocyanin accumulation. The p...

BACKGROUND Shaken baby syndrome often occurs after shaking in response to crying bouts. We questioned whether the use of the educational materials from the Period of PURPLE Crying program would change maternal knowledge and behaviour related to shaking. METHODS We performed a randomized controlled trial in which 1279 mothers received materials from the Period of PURPLE Crying program or contr...
