Behavioral compositions, groups of interdependent objects cooperating to accomplish tasks, are an important feature object-oriented systems. This paper introduces Contracts, a new technique for specifying behavioral compositions and the obligations on participating objects. Refinement composition contracts allows creation large grain abstractions based behavior, orthogonal those provided by existing class constructs. Using thus provides basis vocabulary Interaction-Oriented design which...

Auxin and ethylene are key regulators of plant growth development, thus the transcriptional networks that mediate responses to these hormones have been subject intense research. This study dissected hormonal cross talk regulating synthesis flavonols examined their impact on root development. We analyzed effects auxin an precursor roots wild-type hormone-insensitive Arabidopsis (Arabidopsis thaliana) mutants at transcript, protein, metabolite levels high spatial temporal resolution....
With widespread detection of endocrine disrupting compounds including hormones in wastewater, there is a need to develop cost-effective remediation technologies for their removal from wastewater. Previous research has shown that Fe3+-saturated montmorillonite effective quickly transforming phenolic organic such as pentachlorophenol, acids, and triclosan via surface-catalyzed oligomerization. However, little known about its effectiveness reaction mechanisms when reacting with hormones. In...
Methyl 5-O-(E)-[γ-13C]feruloyl-α-L-arabinofuranoside (FA-Ara) has been synthesized and incorporated into a synthetic lignin dehydrogenation polymer (DHP) of coniferyl alcohol. Inverse-detected long-range C–H correlation NMR experiments on the DHP gave peaks indicative copolymerization FA-Ara alcohol polymer. The bonding sites modes, as determined by analysis carbonyl region correlated 2D experiment, are predictable from free-radical coupling mechanisms. In addition to abundant 4-O-α′ 4-O-β′...

ABSTRACT Active Fe-superoxide dismutase (SodF) was the third most abundant soluble protein in cells of Nostoc commune CHEN/1986 after prolonged (13 years) storage desiccated state. Upon rehydration, Fe-containing superoxide disumutase (Fe-SOD) released and activity distributed between rehydrating extracellular fluid. The 21-kDa Fe-SOD polypeptide purified, N terminus sequenced, data were used to isolate sodF from clonal N. DRH1. encodes an open reading frame 200 codons is expressed as a...
ABSTRACT The structure of the viscous extracellular polysaccharide (glycan) desiccation-tolerant Nostoc commune DRH-1 was determined through chromatographic and spectroscopic methods. is novel in that it possesses a 1-4-linked xylogalactoglucan backbone with d -ribofuranose 3- O -[( R )-1-carboxyethyl]- -glucuronic acid (nosturonic acid) pendant groups. presence -ribose nosturonic as peripheral groups unusual, their potential roles modulating rheological properties glycan are discussed....
The accepted derivation of lignins from non(enzymatically)-controlled radical coupling reactions has been recently challenged, and it is relevant to ascertain unequivocally whether are or not (as normally assumed) optically active. Two approaches were used. First, DFRC (derivatization followed by reductive cleavage) dimers derived β-5- β-β-units in pine lignins, which certainly retain unaltered chiral centers well as β-1- β-O-4-units where the intactness may be debated), shown inactive...
Bacterial chemotaxis is an important attribute that aids in establishing symbiosis between rhizobia and their legume hosts. Plant roots seeds exude a spectrum of molecules into the soil to attract bacterial symbionts. The alfalfa symbiont Sinorhizobium meliloti possesses eight chemoreceptors sense its environment mediate toward host. methyl accepting protein McpU one more abundant S. sensor for potent attractant proline. We established dominant role sensing exuded by seeds. Mass spectrometry...
Given that cellular O-GlcNAcylation levels are thought to be real-time measures of nutrient status and dysregulated O-GlcNAc signaling is associated with insulin resistance, we evaluated the role transferase (OGT), enzyme mediates O-GlcNAcylation, in skeletal muscle. We assessed muscle from obese, type 2 diabetic people, characterized muscle-specific OGT knockout (mKO) mice metabolic cages measured energy expenditure substrate utilization pattern using indirect calorimetry. Whole body...
Amyloid formation of the 37-residue amylin is involved in pathogenesis type 2 diabetes and, potentially, diabetes-induced neurological deficits. Numerous flavonoids exhibit inhibitory effects against amyloidosis, but mechanisms inhibition remain unclear. Screening a library natural compounds uncovered potent lead compound, flavone baicalein. Baicalein inhibits amyloid and reduces amylin-induced cytotoxicity. Analogue analyses demonstrated, for first time, key roles vicinal hydroxyl groups on...
ABSTRACT A transcriptional analysis of the response Saccharomyces cerevisiae strain BY4743 to controlled air-drying (desiccation) and subsequent rehydration under minimal glucose conditions was performed. Expression genes involved in fatty acid oxidation glyoxylate cycle observed increase during drying remained this state phase. When expression profile for dried sample compared that a commercially prepared dry active yeast, strikingly similar changes were observed. The fact these two...
We present an unusual algorithm involving classification trees---CARTwheels---where two trees are grown in opposite directions so that they joined at their leaves. This approach finds application a new data mining task we formulate, called redescription mining. A is shift-of-vocabulary, or different way of communicating information about given subset data; the goal to find subsets afford multiple descriptions. highlight importance this problem domains such as bioinformatics, which exhibit...
