The Recombinase IntA Is Required for Excision of esp-Containing ICEEfm1 in Enterococcus faecium?  

PubMed Central

Comparative genome analysis of Enterococcus faecium recently revealed that a genomic island containing the esp gene, referred to as the esp-containing pathogenicity island (esp PAI), can be transferred by conjugation and contains a partial Tn916-like element and an integrase gene, intA. Here, we characterize the role of intA in the excision of the esp PAI. An intA insertion-deletion mutant in E. faecium E1162 (E1162?intA) was constructed and in trans complemented with wild-type intA (E1162?intA::pEF30). Circular intermediates (CI) of excised esp PAI were determined using inverse PCR analysis on purified chromosomal DNA from strains E1162, E1162?esp, E1162?intA, and E1162?intA::pEF30. In E1162 and E1162?esp, CI of the esp PAI were detected. No CI were detected in E1162?intA, while in the complemented strain E1162?intA::pEF30 CI formation was restored, indicating that intA is essential for excision and subsequent mobilization of the esp-containing genomic island in E. faecium. Based on the fact that this island can be mobilized and is self-transmissible, we propose to change the name of the esp PAI to ICEEfm1.

Characterization of IntA, a Bidirectional Site-Specific Recombinase Required for Conjugative Transfer of the Symbiotic Plasmid of Rhizobium etli CFN42  

PubMed Central

Site-specific recombination occurs at short specific sequences, mediated by the cognate recombinases. IntA is a recombinase from Rhizobium etli CFN42 and belongs to the tyrosine recombinase family. It allows cointegration of plasmid p42a and the symbiotic plasmid via site-specific recombination between attachment regions (attA and attD) located in each replicon. Cointegration is needed for conjugative transfer of the symbiotic plasmid. To characterize this system, two plasmids harboring the corresponding attachment sites and intA were constructed. Introduction of these plasmids into R. etli revealed IntA-dependent recombination events occurring at high frequency. Interestingly, IntA promotes not only integration, but also excision events, albeit at a lower frequency. Thus, R. etli IntA appears to be a bidirectional recombinase. IntA was purified and used to set up electrophoretic mobility shift assays with linear fragments containing attA and attD. IntA-dependent retarded complexes were observed only with fragments containing either attA or attD. Specific retarded complexes, as well as normal in vivo recombination abilities, were seen even in derivatives harboring only a minimal attachment region (comprising the 5-bp central region flanked by 9- to 11-bp inverted repeats). DNase I-footprinting assays with IntA revealed specific protection of these zones. Mutations that disrupt the integrity of the 9- to 11-bp inverted repeats abolish both specific binding and recombination ability, while mutations in the 5-bp central region severely reduce both binding and recombination. These results show that IntA is a bidirectional recombinase that binds to att regions without requiring neighboring sequences as enhancers of recombination.

Digitization, Integration and Preservation of Technical and Historical Information: The Case of INTA, the National Institute for Aerospace Technique of Spain  

NASA Astrophysics Data System (ADS)

During the last two years the INTA -- National Institute for Aerospace Technique -- library has been improving different areas related to the information management processes, such as those related to cataloguing, dissemination of technical information, centralization at the Library of all relevant documents and information applicable to scientific research within our organization, implementation of library web services, etc. As part of these processes of modernization of services that the INTA Library is carrying out, a project of digitization of both technical documentation and historical records of the Institute has been defined. The goal is to achieve the total digitization of technical documents and historical papers through the year 2006, and provide access for the resulting electronic collection to the Spanish aerospace community. For the development of the project a deep study of the state of the art in digitization and preservation matters has been conducted. That study covers the different aspects of such a project that could be experienced, such as the risk of data loss, the bandwidth needed to guarantee access to this huge quantity of electronic documentation, the fragility of the digital media, the rapid obsolescence of hardware and software, etc. Also the project is going to assume the new reality of documents that are not originating in paper format, but are digital-born, and how to integrate all the electronic documents in one system, fulfilling the same standards and using the same available technology.

Complete sequence of three plasmids from Bacillus thuringiensis INTA-FR7-4 environmental isolate and comparison with related plasmids from the Bacillus cereus group.  

PubMed

Bacillus thuringiensis is an insect pathogen used worldwide as a bioinsecticide. It belongs to the Bacillus cereus sensu lato group as well as Bacillus anthracis and B. cereus. Plasmids from this group of organisms have been implicated in pathogenicity as they carry the genes responsible for different types of diseases that affect mammals and insects. Some plasmids, like pAW63 and pBT9727, encode a functional conjugation machinery allowing them to be transferred to a recipient cell. They also share extensive homology with the non-functional conjugation apparatus of pXO2 from B. anthracis. In this study we report the complete sequence of three plasmids from an environmental B. thuringiensis isolate from Argentina, obtained by a shotgun sequencing method. We obtained the complete nucleotide sequence of plasmids pFR12 (12,095bp), pFR12.5 (12,459bp) and pFR55 (55,712bp) from B. thuringiensis INTA-FR7-4. pFR12 and pFR12.5 were classified as cryptic as they do not code for any obvious functions besides replication and mobilization. Both small plasmids were classified as RCR plasmids due to similarities with the replicases they encode. Plasmid pFR55 showed a structural organization similar to that observed for plasmids pAW63, pBT9727 and pXO2. pFR55 also shares a tra region with these plasmids, containing genes related to T4SS and conjugation. A comparison between pFR55 and conjugative plasmids led to the postulation that pFR55 is a conjugative plasmid. Genes related to replication functions in pFR55 are different to those described for plasmids with known complete sequences. pFR55 is the first completely sequenced plasmid with a replication machinery related to that of ori44. The analysis of the complete sequence of plasmids from an environmental isolate of B. thuringiensis permitted the identification of a near complete conjugation apparatus in pFR55, resembling those of plasmids pAW63, pBT9727 and pXO2. The availability of this sequence is a step forward in the study of the molecular basis of the conjugative process in Gram positive bacteria, particularly due to the similarity with known conjugation systems. It is also a contribution to the expansion of the non-pathogenic B. cereus plasmid gene pool. PMID:19654019

Stop place coding: an acoustic study of CV, VC#, and C#V sequences.  

PubMed

This study investigated stop + vowel coarticulation as a coding mechanism for differentiation of stop place categories in an F2-defined stimulus space. Locus equations (LEs) were used to index the extent of coarticulation in three contexts: (1) onset stop + vowel utterances [.CV]; (2) within-syllable vowel + coda stop utterances [VC#], and (3) across-syllable/word coda stop + vowel utterances [C#V]. Five speakers of American English and 2 speakers of Persian produced [CV1.CV2] (English and Persian), [tV1C#V2t] (English) and [dV1C#V2t] (Persian) tokens with voiced labial, alveolar/dental, and velar stops surrounded by a variety of vowels. In the across-syllable/word boundary condition [C#V2] the extent of anticipatory coarticulation was much reduced relative to traditionally measured onset [CV2] syllables. LE slopes derived across the syllable/word boundary, however, still differed between stop places in the same order as onset CVs. LE slopes derived from within-syllable [V1C#] sequences, however, did not differ between stop places. PMID:15258455

Iterative contextual CV model for liver segmentation  

NASA Astrophysics Data System (ADS)

In this paper, we propose a novel iterative active contour algorithm, i.e. Iterative Contextual CV Model (ICCV), and apply it to automatic liver segmentation from 3D CT images. ICCV is a learning-based method and can be divided into two stages. At the first stage, i.e. the training stage, given a set of abdominal CT training images and the corresponding manual liver labels, our task is to construct a series of self-correcting classifiers by learning a mapping between automatic segmentations (in each round) and manual reference segmentations via context features. At the second stage, i.e. the segmentation stage, first the basic CV model is used to segment the image and subsequently Contextual CV Model (CCV), which combines the image information and the current shape model, is iteratively performed to improve the segmentation result. The current shape model is obtained by inputting the previous automatic segmentation result into the corresponding self-correcting classifier. The proposed method is evaluated on the datasets of MICCAI 2007 liver segmentation challenge. The experimental results show that we obtain more and more accurate segmentation results by the iterative steps and satisfying results are obtained after about six iterations. Also, our method is comparable to the state-of-the-art work on liver segmentation.

EARTH, MOON, SUN, AND CV ACCRETION DISKS  

SciTech Connect

Net tidal torque by the secondary on a misaligned accretion disk, like the net tidal torque by the Moon and the Sun on the equatorial bulge of the spinning and tilted Earth, is suggested by others to be a source to retrograde precession in non-magnetic, accreting cataclysmic variable (CV) dwarf novae (DN) systems that show negative superhumps in their light curves. We investigate this idea in this work. We generate a generic theoretical expression for retrograde precession in spinning disks that are misaligned with the orbital plane. Our generic theoretical expression matches that which describes the retrograde precession of Earths' equinoxes. By making appropriate assumptions, we reduce our generic theoretical expression to those generated by others, or to those used by others, to describe retrograde precession in protostellar, protoplanetary, X-ray binary, non-magnetic CV DN, quasar, and black hole systems. We find that spinning, tilted CV DN systems cannot be described by a precessing ring or by a precessing rigid disk. We find that differential rotation and effects on the disk by the accretion stream must be addressed. Our analysis indicates that the best description of a retrogradely precessing spinning, tilted, CV DN accretion disk is a differentially rotating, tilted disk with an attached rotating, tilted ring located near the innermost disk annuli. In agreement with the observations and numerical simulations by others, we find that our numerically simulated CV DN accretion disks retrogradely precess as a unit. Our final, reduced expression for retrograde precession agrees well with our numerical simulation results and with selective observational systems that seem to have main-sequence secondaries. Our results suggest that a major source to retrograde precession is tidal torques like that by the Moon and the Sun on the Earth. In addition, these tidal torques should be common to a variety of systems where one member is spinning and tilted, regardless if accretion disks are present or not. Our results suggest that the accretion disk's geometric shape directly affects the disk's precession rate.

Physicochemical characterization of a new pineapple hybrid (FLHORAN41 Cv.).  

PubMed

The physicochemical characteristics (pH, total and soluble solids, and titratable acidity), sugars, organic acids, carotenoids, anthocyanins, volatile compounds, and cell wall polysaccharides of a new pineapple hybrid (FLHORAN41 cultivar) were measured throughout maturation and compared with the Smooth Cayenne cv. At full maturity, the FLHORAN41 cv. has a higher titratable acidity and soluble solids content than the Smooth Cayenne cv. The golden yellow flesh and red-orange to scarlet shell of ripe FLHORAN41 cv. fruits are due to carotenoid and anthocyanin levels that are, respectively, 2.5 and 1.5 times higher than those of the flesh and shell of the ripe Smooth Cayenne cv., respectively. During maturation of the FLHORAN41 cv., there was an increase in all classes of aroma compounds (mainly terpene hydrocarbons and esters), although their relative proportions were similar in both cultivars at full maturity. Cell wall polysaccharides undergo little change during maturation. PMID:15453683

Protective effect of CV247 against cisplatin nephrotoxicity in rats.  

PubMed

CV247 (CV), an aqueous mixture of copper (Cu) and manganese (Mn) gluconates, vitamin C and sodium salicylate increased the antitumour effects of cisplatin (CDPP; cis-diamminedichloroplatinum) in vitro. We hypothesized that the antioxidant and cyclooxygenase-2 (COX-2; prostaglandin-endoperoxide synthase 2) inhibitory components of CV can protect the kidneys from CDPP nephrotoxicity in rats. CDPP (6.5 mg/kg, intraperitoneally) slightly elevated serum creatinine (Crea) and blood urea nitrogen (BUN) 12 days after treatment. Kidney histology demonstrated extensive tubular epithelial damage and COX-2 immunoreactivity increased 14 days after treatment. A large amount of platinum (Pt) accumulated in the kidney of CDPP-treated rats. Furthermore, CDPP decreased renal iron (Fe), molybdenum (Mo), zinc (Zn), Cu and Mn concentrations and increased plasma Fe and Cu concentrations. CDPP elevated plasma free radical concentration. Treatment with CV alone for 14 days (twice 3 ml/kg/day orally) did not influence these parameters. Chronic CV administration after CDPP reduced renal histological damage and slightly decreased COX-2 immunoreactivity, while failed to prevent the increase in Crea and BUN levels. Blood free radical concentration was reduced, that is, CV improved redox homeostasis. CV restored plasma Fe and renal Fe, Mo and Zn, while decreased Pt and elevated Cu and Mn concentrations in the kidney. Besides the known synergistic antitumour effects with CDPP, CV partially protected the kidneys from CDPP nephrotoxicity probably through its antioxidant effect. PMID:23653282

Opaque Assemblages in CK and CV Carbonaceous Chondrites  

NASA Technical Reports Server (NTRS)

CK carbonaceous chondrites are the only group of carbonaceous chondrites that exhibit thermal metamorphism. As a result, CKs display features of metamorphism such as silicate darkening, recrystallization and shock veins. Calcium Aluminum Inclusions and Fe-Ni metal are rare. CV carbonaceous chondrites are unequilibrated and have two subgroups; oxidized and reduced. The CV and CK carbonaceous chondrite groups have been compared to each other often because of petrographic similarities, such as overlapping oxygen isotopic ratios. Scientists have suggested the two groups of carbonaceous chondrites formed from the same parent body and CKs are equilibrated CV chondrites [1, 2]. The oxidized CV group has been most closely related to CKs. This study examines the petrology and mineralogy of CKs and CVs focusing on opaque minerals found in the meteorites. Using the oxide, metal and sulfide assemblages, constraints can be placed on the temperature and oxygen fugacity at which the meteorites equilibrated. The temperature and oxygen fugacity of the CK and CV chondrites can be compared in order to help define their formation history.

This finding, along with the recent discovery of another obscured supernova, suggests a critical revision of the rates known to date. The estimate of the visual extinction and the light curves are provided here. These latter indicate that our SN 2002cv observations are the earliest available for a type-Ia supernova at IR wavelengths.

Axtrell, a new CV3 chondrite find from Texas  

NASA Technical Reports Server (NTRS)

We describe a previously unreported meteorite found in Axtell, Texas, in 1943. Based on the mineralogical composition and texture of its matrix and the sizes and abundance of chondrules, we classify it as a CV3 carbonaceous chondrite. The dominant opaque phase in the chondrules is magnetite, and that in refractory inclusions is Ni-rich metal (awaruite). Axtell, therefore, belongs to the oxidized subgroup of CV3 chondrites, although unlike Allende it escaped strong sulfidation. The meteorite bears a strong textural resemblance to Allende, and its chondrule population and matrix appear to be quite similar to those of Allende, but its refractory inclusions, thermoluminescence properties, and cosmogenic Co-60 abundances are not. Our data are consistent with a terrestrial age for Axtell of approximately 100 years and a metamorphic grade slightly lower than that of Allende.

Memory immune response and safety of a booster dose of Japanese encephalitis chimeric virus vaccine (JE-CV) in JE-CV-primed children  

PubMed Central

Japanese encephalitis chimeric virus vaccine (JE-CV) is a licensed vaccine indicated in a single dose administration for primary immunization. This controlled phase III comparative trial enrolled children aged 36–42 mo in the Philippines. 345 children who had received one dose of JE-CV in a study two years earlier, received a JE-CV booster dose. 105 JE-vaccine-naïve children in general good health were randomized to receive JE-CV (JE-vaccine naïve group; 46 children) or varicella vaccine (safety control group; 59 children). JE neutralizing antibody titers were assessed using PRNT50. Immunological memory was observed in children who had received the primary dose of JE-CV before. Seven days after the JE-CV booster dose administration, 96.2% and 66.8% of children were seroprotected and had seroconverted, respectively, and the geometric mean titer (GMT) was 231 1/dil. Twenty-eight days after the JE-CV booster dose seroprotection and seroconversion were achieved in 100% and 95.3% of children, respectively, and the GMT was 2,242 1/dil. In contrast, only 15.4% of JE-CV-vaccine naïve children who had not received any prior JE vaccine were seroprotected seven days after they received JE-CV. One year after receiving the JE-CV booster dose, 99.4% of children remained seroprotected. We conclude that JE-CV is effective and safe, both as a single dose and when administrated as a booster dose. A booster dose increases the peak GMT above the peak level reached after primary immunization and the antibody persistence is maintained at least one year after the JE-CV booster dose administration. Five year follow up is ongoing.

A Primitive Achondrite With Oxygen Isotopic Affinities to CV Chondrites: Implications for Differentiation and Size of the CV Parent Body  

NASA Astrophysics Data System (ADS)

NWA 3133 found in Northwest Africa (as several stones totaling ˜ 4 kg) has a metamorphic texture with ˜120° triple grain junctions (mean grainsize = 0.28 mm); no chondrules are present. Olivine (46 vol.%; Fa22, FeO/MnO = 64) and orthopyroxene (28 vol.%; Fs18.9Wo2.3, FeO/MnO = 42) are the most abundant phases, with less intermediate plagioclase (An53.5Or2.3), Cr-diopside (Fs7.5Wo48.3, Cr2O3 = 0.71 wt.%), Al-Ti-bearing chromite (Cr/(Cr+Al) = 0.73, TiO2 = 2.6 wt.%), Na-Mg-bearing merrillite, troilite (1-5 wt.% Ni) and Fe-Ni metal (15-20 wt.% Ni). Clinopyroxene, chromite and merrillite are inhomogeneously distributed as relatively large grains. Metal is partially altered to limonite (W1-2), and minor limonite and calcite occur along grain boundaries. Oxygen isotopic compositions (? 17O, ? 18O) determined in two laboratories by laser fluorination on handpicked olivine (-3.67, +0.94; -3.62, +0.89; -2.91, +1.78 per mil) and on acid-washed whole rock fragments (-2.25, +2.46; -1.75, +3.06 per mil) plot on the mixing line for Allende and other CV3 chondrites. Thus, NWA 3133 could be regarded as the first known "CV7 chondrite", and may have been formed by metamorphic recrystallization (or perhaps igneous processes) in the CV parent body. Other meteorites with oxygen and/or Cr isotopic affinities to the CV3 chondrites are the three members of the Eagle Station pallasite grouplet and the silicated irons Bocaiuva and NWA 176 (Clayton and Mayeda., 1996; Liu et al, 2001; Shukolyukov and Lugmair, 2001). Our inference from these data is that the CV parent body was an at least partially differentiated (and relatively large) object consisting of a metal+silicate core region surrounded by a presumably silicate-rich mantle and a chondrule-CAI-rich regolith, the deepest portions of which were metamorphosed and/or partially melted to form primitive achondritic lithologies.

Application of solid-phase microextraction and simultaneous distillation-extraction combined with GC-FID, GC-MS, aroma extract dilution analysis, and odour activity value were used to analyse volatile compounds from papaya fruit cv. Red Maradol and to estimate the most odour-active compounds. The analyses led to the identification of 137 compounds; 118 of them were positively identified. Twenty-five odorants were considered as odour-active compounds and contribute to the typical papaya aroma, from which ethyl butanoate, benzyl isothiocyanate, 1-hexen-3-one, (E)-?-ionone, and methyl benzoate were the most odour-active compounds.

PubMed

In this research, several physical, pomological and nutritional properties that are important for the design of equipments for harvesting, processing, transportation, sorting, separation and packaging of kiwifruit cv. Hayward grown in the Black Sea region of Turkey were determined. The fruit characteristics ranged from 72.28 g for average fruit weight, 59.41, 46.28 and 42.87 mm for fruit length, width and thickness, 49.03 mm for the geometric mean diameter, 0.825% for sphericity and 66.52 cm(3) for the volume of fruit, respectively. The bulk density, fruit density and porosity were determined as 575.27 kg/m(3), 1,093 kg/m(3) and 47.13%. The highest coefficient of static friction was obtained on plywood as 0.190, followed by polyethylene, rubber and galvanized steel sheet as 0.173, 0.163 and 0.158, respectively. The total soluble solid content, acidity, vitamin C, ash and total nitrogen content of kiwifruit cv. Hayward were 7.32%, 1.64%, 108 mg/100g, 0.71 g/100 g and 0.84%, respectively.

CV-6209, a highly potent antagonist of platelet activating factor in vitro and in vivo.  

PubMed

2-[N-acetyl-N-(2-methoxy-3-octadecylcarbamoyloxypropoxycarbonyl) aminomethyl]-1-ethylpyridinium chloride (CV-6209) inhibited aggregation of rabbit and human platelets induced by platelet activating factor (PAF) with the IC50 values of 7.5 X 10(-8) and 1.7 X 10(-7) M, respectively, and had little effects on the aggregation induced by arachidonic acid, ADP and collagen. The inhibitory effect of CV-6209 on the PAF-induced rabbit platelet aggregation was 104, 9, 8 and 3 times more potent than the PAF antagonists CV-3988, ONO-6240, Ginkgolide B and etizolam, respectively. CV-6209 inhibited [3H]serotonin release from rabbit platelets stimulated with PAF (3 X 10(-8) M) with a similar potency as the inhibition on the platelet aggregation. CV-6209 inhibited PAF (0.3 microgram/kg i.v.)-induced hypotension in rats (ED50, 0.009 mg/kg i.v.) with no effect on the hypotension induced by arachidonic acid, histamine, bradykinin and isoproterenol. CV-6209 (1 mg/kg) inhibited slightly the acetylcholine-induced hypotension. In rats, post-treatment with CV-6209 reversed the PAF (1 microgram/kg i.v.)-induced hypotension rapidly (ED50, 0.0046 mg/kg i.v.); CV-6209 was 74, 20, 185 and over 2100 times more potent than CV-3988, ONO-6240, Ginkgolide B and etizolam, respectively. Thus, the relative potency of the anti-PAF action of PAF analog (CV-6209, CV-3988 and ONO-6240) differed little between the inhibition of PAF-induced platelet aggregation and the reversal of PAF-induced hypotension, but that of nonPAF analogs (Ginkgolide B and etizolam) differed greatly with these assay systems, when standardized with CV-6209.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3612533

Collisional facilitation of aqueous alteration of CM and CV carbonaceous chondrites  

NASA Astrophysics Data System (ADS)

CM chondrites exhibit a strong correlation between the degree of alteration and the extent of particle alignment (i.e., the strength of the petrofabric). It seems likely that the S1 shock stage of essentially every CM and the high matrix abundance (˜70 vol.%) of these samples ensured that the shock waves that produced CM petrofabrics (by collapsing matrix pores and squeezing chondrules into pore spaces) were significantly attenuated and were too weak to damage olivine crystal lattices. Random collisions on the CM body produced petrofabrics and created fractures in the target rocks. Subsequent impact-mobilization of water caused hydrated phases to form preferentially in the more-fractured regions (those with the strongest petrofabrics); the less-deformed, less-fractured CM regions experienced lower degrees of aqueous alteration. Many CV3 chondrites also have petrofabrics: roughly half are from the oxidized Bali-like subgroup (CV3OxB), roughly half are from the reduced subgroup (CV3R) and none is from the oxidized Allende-like subgroup (CV3OxA) (which is less altered than CV3OxB). Nearly all CVs with petrofabrics are S3-S4 and nearly all CVs that lack petrofabrics are S1. Oxidized CVs have much higher porosities (typically 20-28%) than reduced CVs (0.6-8%), facilitating more-extensive aqueous alteration. The CV3R chondrites formed from low-porosity material that inhibited oxidation during alteration. The oxidized CV subgroups formed from higher-porosity materials. The CV3OxB samples were shocked, became extensively fractured and developed petrofabrics; the CV3OxA samples were not shocked and never developed petrofabrics. When water was mobilized, both sets of porous CV chondrites became oxidized; the more-fractured CV3OxB subgroup was more severely altered.

Experimental Aqueous Alteration of the Allende CV3 Chondrite  

NASA Astrophysics Data System (ADS)

Aqueous alteration is an important process that prevailed in the early solar system. In order to better understand the aqueous alteration processes and conditions, we embarked in hydrothermal alteration experiments of the Allende CV3 chondrite. We here present the first results of our experiments. Samples of Allende were sealed in gold tubes with 1-N HCl and heated in a reactor vessel at 450 degrees C and 800 bars for 4 to 6 weeks. Thin sections were made from the run products and were observed and analyzed by a scanning electron microscope equipped with an EDS spectrometer. Our experiments produced remarkable alteration textures in the Allende chondrite. Parts of internal areas of most of the chondrules are replaced by brownish-to-greenish phyllosilicate, exhibiting an appearance closely similar to the altered ("spinach"-bearing) chondrules in CM chondrites. Fractures and interstices in chondrules and matrix, up to 20 micrometers in width and 1 mm in length, are filled with phyllosilicate, producing remarkable veins similar to those observed in CI chondrites. Mainly two kinds of phyllosilicates were produced. One contains major Mg and Fe and has compositions similar to Fe-rich saponite. This is the most common phyllosilicate that occurs in both chondrules and matrix; it is primarily formed by replacing olivine and low-Ca pyroxene. The other kind of phyllosilicate contains major Mg and Fe and variable Al; it is probably a mixture of two phases, so we tentatively call it high-Al phyllosilicates (HAP). HAP occurs mainly in chondrule mesostasis, where it is formed by replacing mesostasis glass. Chondrules and aggregates are altered from their edges to inward. Olivine in outer areas of chondrules and aggregates are enriched in Fe, and most of individual olivine grains show strong Fe-Mg zoning, indicating substantial Fe was added from matrix to chondrules. Mesostasis in central areas is preferentially replaced by HAP, while that in outer areas is replaced by saponite. There are remarkable differences in degree of alteration by phyllosilicates among the precursor minerals in chondrules. The resistance to alteration increases in the order, glass, low-Ca pyroxene, olivine. Aggregates of Fe-rich saponite ranging in diameter from 10 to 50 micrometers are produced in places in matrix. However, most of small original olivine grains (1 to 10 micrometers in diameter) still remain unaltered. This is surprising to us, taking into account the fact that chondrule internals were altered to the extent up to 200x200 micrometers^2 in area. This indicates that the alteration proceeds much faster in chondrule mesostasis than in the fine-grained matrix. Drastic chemical exchanges took place between chondrules and matrix. Among major elements, Fe was added from matrix to chondrules mainly as an olivine component, whereas Mg, Al, Ca, Na and S were lost from chondrules. In chondrule mesostasis, Ca is almost completely lost, confirming that the mobility of Ca is particularly high. As a result of these elemental exchanges, the meteorite became homogenized as a whole. The texture and the phyllosilicate mineralogy produced in the altered Allende samples are closely similar to those observed in the Mokoia and Kaba CV3 chondrites [1,2]. These similarities suggest that the alteration in Mokoia and Kaba occurred in situ on the CV parent body under conditions somewhat related to the present experimental condition, although the pressure and temperature should have been much lower than those used in our experiments.

Linear and nonlinear interpretation of CV-580 lightning data  

NASA Technical Reports Server (NTRS)

Numerical models developed for the study of lightning strike data acquired by in-flight aircraft are applied to the data measured on the CV-580. The basic technique used is the three dimensional time domain finite difference solution of Maxwell's equations. Both linear and nonlinear models are used in the analysis. In the linear model, the lightning channel and the aircraft are assumed to form a linear time invariant system. A transfer function technique can then be used to study the response of the aircraft to a given lightning strike current. Conversely, the lightning current can be inferred from the measured response. In the nonlinear model, the conductivity of air in the vicinity of the aircraft is calculated and incorporated into the solution of the Maxwell's equations. The nonlinear model thus simulates corona formation and air breakdown. Results obtained from the models are in reasonable agreement with the measured data. This study provides another validation of the models and increases confidence that the models may be used to predict aircraft response to any general lightning strike.

Factors affecting somatic embryogenesis in Prunus incisa cv. February Pink.  

PubMed

Factors affecting somatic embryogenesis from root explants of Prunus incisa Thunb. cv. February Pink were investigated. Using a medium containing Murashige and Skoog salts and vitamins supplemented with 10 microM 2,4-dichlorophenoxyacetic (2,4-D), we evaluated the effects of light, growth regulators, amino acids, carbohydrate source, and root induction medium. Explants cultured under light or dark conditions both resulted in the formation of embryos. Embryogenesis was inhibited by the addition of 6-benzyladenine, thidiazuron, or gibberellic acid to the medium. Amino acids were not effective in promoting embryogenesis, with high levels of amino acids actually inhibiting it. Sucrose and glucose effectively induced embryogenesis, while sorbitol and mannitol completely inhibited it. Sucrose and glucose also promoted secondary embryogenesis. Embryos that formed in medium containing 4% or 5% sucrose were abnormally shaped and did not fully develop, while those that formed in medium with sucrose concentrations of 2% or 3% were much more vigorous. Root explants that were induced on medium containing 1.0 micro M indole-3-butyric acid (IBA) produced more somatic embryos than explants induced on medium without IBA. Approximately 50% of the roots induced on medium containing 1.0 microM IBA produced somatic embryos on medium containing 10 microM 2,4-D and 3% sucrose. PMID:15022015

Morphological Analyses of Spring Wheat (CIMMYT cv. PCYT-10) Somaclones  

NASA Technical Reports Server (NTRS)

The objectives of this study were to induce callus from single immature wheat embryos, produce multiple seedlings from the induced callus, and analyse the somaclonal regenerants for potential grain production in a space garden. Immature wheat, Triticum aestivum L. (cv. PCYT-10), embryos were excised 10 to 12 days post-anthesis and cultured on modified Murashige and Skoog's inorganic salts. Embryos cultured on medium containing kinetin (6-furfurylaminopurine) at 0.5mg/l plus 2 or 3mg/l dicamba (1-methoxy-3,6- dichlorobenzoic acid) or 0.2mg/l 2,4-dichlorophenoxyacetic acid produced calli from which 24, 35 and 39% of the explant tissue exhibited regenerants, respectively. The size of flag leaves, plant heights, tillers per plant, spike lengths, awn lengths, and seeds per spike were significantly different in regenerants of two-selfed recurrent generations (SC(sub 1), SC(sub 2)) than in parental controls. However, there were no significant differences in spikelets per spike between the SC(sub 2) and parental controls. Desirable characteristics that were obtained included longer spikes, more seeds per spike, supernumerary spikelets, and larger flag leaves, variants that should be useful in wheat improvement programs.

Seven health physics calculator programs for the HP-41CV  

SciTech Connect

Several user-oriented programs for the Hewlett-Packard HP-41CV are explained. The first program builds, stores, alters, and ages a list of radionuclides. This program only handles single- and double-decay chains. The second program performs convenient conversions for the six nuclides of concern in plutonium handling. The conversions are between mass, activity, and weight percents of the isotopes. The source can be aged and/or neutron generation rates can be computed. The third program is a timekeeping program that improves the process of manually estimating and tracking personnel exposure during high dose rate tasks by replacing the pencil, paper, and stopwatch method. This program requires a time module. The remaining four programs deal with computations of time-integrated air concentrations at various distances from an airborne release. Building wake effects, source depletion by ground deposition, and sector averaging can all be included in the final printout of the X/Q - Hanford and X/Q - Pasquill programs. The shorter versions of these, H/Q and P/Q, compute centerline or sector-averaged values and include a subroutine to facilitate dose estimation by entering dose factors and quantities released. The horizontal and vertical dispersion parameters in the Pasquill-Gifford programs were modeled with simple, two-parameter functions that agreed very well with the usual textbook graphs. 8 references, 7 appendices.

Magnetic characteristics of CV chondrules with paleointensity implications  

NASA Astrophysics Data System (ADS)

We have conducted a detailed magnetic study on 45 chondrules from two carbonaceous chondrites of the CV type: (1) Mokoia and (2) Allende. Allende has been previously extensively studied and is thought to have a high potential of retaining an extra-terrestrial paleofield. Few paleomagnetic studies of Mokoia have previously been undertaken. We report a range of magnetic measurements including hysteresis, first-order reversal curve analysis (FORCs), demagnetization characteristics, and isothermal remanent (IRM) acquisition behavior on both Mokoia and Allende chondrules. The Mokoia chondrules displayed more single domain-like behavior than the Allende chondrules, suggesting smaller grain sizes and higher magnetic stability. The Mokoia chondrules also had higher average concentrations of magnetic minerals and a larger range of magnetic characteristics than the Allende chondrules. IRM acquisition analysis found that both sets of chondrules have the same dominant magnetic mineral, likely to be a FeNi phase (taenite, kamacite, and/or awaruite) contributing to 48% of the Mokoia chondrules and 42% of the Allende chondrule characteristics. FORC analysis revealed that generally the Allende chondrules displayed low-field coercivity distributions with little interactions, and the Mokoia chondrules show clear single-domain like distributions. Paleointensity estimates for the two meteorites using the REMc and Preisach methods yielded estimates between 13 and 60 ?T and 3-56 ?T, respectively, for Allende and 3-140 ?T and 1-110 ?T, respectively, for Mokoia. From the data, we suggest that Mokoia chondrules carry a non-primary remagnetization, and while Allende is more likely than Mokoia to retain its primary magnetization, it also displays signs of post accretionary magnetization.

A novel cyclovirus, CyCV-VN, was recently identified in cerebrospinal fluid (CSF) from patients with central nervous system (CNS) infections in central and southern Vietnam. To explore the geographic distribution of this novel virus, more than 600?CSF specimens from patients with suspected CNS infections in northern Vietnam, Cambodia, Nepal and The Netherlands were screened for the presence of CyCV-VN but all were negative. Sequence comparison and phylogenetic analysis between CyCV-VN and another novel cyclovirus recently identified in CSF from Malawian patients indicated that these represent distinct cycloviral species, albeit phylogenetically closely related. The data suggest that CyCV-VN has a limited geographic distribution within southern and central Vietnam. Further research is needed to determine the global distribution and diversity of cycloviruses and importantly their possible association with human disease. PMID:24495921

Direct extraction of mobility in pentacene OFETs using CV and IV measurements  

Microsoft Academic Search

Mobility was extracted from top-contact pentacene organic field effect transistors with minimal assumptions. Low-frequency capacitance-voltage (C-V) measurements were used to calculate the sheet charge density of the channel, and current-voltage measurements with low drain-to-source voltage were used to extract mobility. The separation of charge and mobility with the use of C-V measurements illustrates that the mobility increases with gate voltage,

Phyllosilicates in the Mokoia CV carbonaceous chondrite - Evidence for aqueous alteration in an oxidizing environment  

NASA Astrophysics Data System (ADS)

Most CV chondrites contain little if any phyllosilicate mineralization. A petrographic and transmission electron microscopy study of the Mokoia CV carbonaceous chondrite shows that the matrix, chondrules, aggregates, and inclusions all contain considerable amounts of phyllosilicates. The mineralogy and occurrence of phyllosilicates in Mokoia differ from those in the CI and CM chondrites. The differences suggests that aqueous alteration of the three meteorite groups probably occurred under a variety of conditions.

[Habitat factor analysis for Torreya grandis cv. Merrillii based on spatial information technology].  

PubMed

Torreya grandis cv. Merrillii, a tertiary survival plant, is a rare tree species of significant economic value and expands rapidly in China. Its special habitat factor analysis has the potential value to provide guide information for its planting, management, and sustainable development, because the suitable growth conditions for this tree species are special and strict. In this paper, the special habitat factors for T. grandis cv. Merrillii in its core region, i.e., in seven villages of Zhuji City, Zhejiang Province were analyzed with Principal Component Analysis (PCA) and a series of data, such as IKONOS image, Digital Elevation Model (DEM), and field survey data supported by the spatial information technology. The results showed that T. grandis cv. Merrillii exhibited high selectivity of environmental factors such as elevation, slope, and aspect. 96.22% of T. grandis cv. Merrillii trees were located at the elevation from 300 to 600 m, 97.52% of them were found to present on the areas whose slope was less than 300, and 74.43% of them distributed on sunny and half-sunny slopes. The results of PCA analysis indicated that the main environmental factors affecting the habitat of T. grandis cv. Merrillii were moisture, heat, and soil nutrients, and moisture might be one of the most important ecological factors for T. grandis cv. Merrillii due to the unique biological and ecological characteristics of the tree species. PMID:19238862

Visualization of HDF/HDF-EOS Format Earth Observing System Data Using the ISIS "cv" Program  

NASA Astrophysics Data System (ADS)

The "cv" (Cube Visualization) program has been used for a number of years as part of the ISIS image processing system (Integrated Software for Imagers and Spectrometers) [1],[2]. In addition to reading the native ISIS image cube format, "cv" has recently been enhanced to directly read the HDF and HDF-EOS file formats used for distributing data from various Earth Observing System (EOS) Missions (e.g. the Terra and Landsat-7 satellites). Files based on HDF Version 4.x are supported; files based on the new HDF 5.x are not yet supported. "cv" is now packaged so that it can be used without installing the rest of the ISIS software system. The capabilities of the program include: Displays (as images) any Swath/Grid data fields in HDF-EOS files; Displays (as images) any Scientific Data Set (SDS) data fields in HDF files; Combines multiple HDF/HDF-EOS fields to form one display object; Subarea selection and/or subsampling (allows handling large files); Simultaneous display of multiple images/files; Plots intensity profiles along any of the three axes in a 3D data set; Writes displayed data fields to binary files (allows doing further processing using ISIS programs or using other software packages); Reports cursor location and pixel value (includes reporting Latitude/Longitude with optional conversion between geocentric and geographic coordinates); Includes many additional flexible display options. The "cv" program is implemented in the IDL language and makes use of the IDL CALL_EXTERNAL capability to call I/O and utility routines written in C and Fortran. Pre-compiled versions of "cv" are available for Sun Solaris, Compaq Alpha and PC Linux platforms. To obtain "cv", go to the USGS anonymous ftp site (ftpflag.wr.usgs.gov). Do a "cd dist/isis" and get (in binary mode) the README_CV.TXT file (installation instructions) and the tar file for the desired platform (cv_sun.tar, cv_alpha.tar, cv_pc.tar). More information on ISIS is available at the ISIS website (http://wwwflag.wr.usgs.gov/ISIS).

Circulating HFMD-Associated Coxsackievirus A16 Is Genetically and Phenotypically Distinct from the Prototype CV-A16  

PubMed Central

Human enteroviruses (HEV) have been linked to hand, foot, and mouth disease (HFMD) in the Pacific and Southeast Asia for decades. Many cases of HFMD have been attributed to coxsackievirus A16 (CV-A16, CA16), based on only partial viral genome determination. Viral phenotypes are also poorly defined. Herein, we have genetically and phenotypically characterized multiple circulating CV-A16 viruses from HFMD patients and determined multiple full-length sequences of these circulating viruses. We discovered that the circulating CV-A16 viruses from HFMD patients are genetically distinct from the proto-type CV-A16 G10. We have also isolated circulating CV-A16 viruses from hospitalized HFMD patients and compared their virological differences. Interestingly, circulating CV-A16 viruses are more pathogenic in a neonatal mouse model than is CV-A16 G10. Thus, we have found circulating recombinant forms of CV-A16 (CRF CV-A16) that are related to, but different from, the prototype CV-A16 G10 that have distinct biological phenotypes.

Solution NMR Structure of Hypothetical Protein CV_2116 Encoded by a Viral Prophage Element in Chromobacterium violaceum  

PubMed Central

CV_2116 is a small hypothetical protein of 82 amino acids from the Gram-negative coccobacillus Chromobacterium violaceum. A PSI-BLAST search using the CV_2116 sequence as a query identified only one hit (E = 2e?07) corresponding to a hypothetical protein OR16_04617 from Cupriavidus basilensis OR16, which failed to provide insight into the function of CV_2116. The CV_2116 gene was cloned into the p15TvLic expression plasmid, transformed into E. coli, and 13C- and 15N-labeled NMR samples of CV_2116 were overexpressed in E. coli and purified for structure determination using NMR spectroscopy. The resulting high-quality solution NMR structure of CV_2116 revealed a novel ? + ? fold containing two anti-parallel ?-sheets in the N-terminal two-thirds of the protein and one ?-helix in the C-terminal third of the protein. CV_2116 does not belong to any known protein sequence family and a Dali search indicated that no similar structures exist in the protein data bank. Although no function of CV_2116 could be derived from either sequence or structural similarity searches, the neighboring genes of CV_2116 encode various proteins annotated as similar to bacteriophage tail assembly proteins. Interestingly, C. violaceum exhibits an extensive network of bacteriophage tail-like structures that likely result from lateral gene transfer by incorporation of viral DNA into its genome (prophages) due to bacteriophage infection. Indeed, C. violaceum has been shown to contain four prophage elements and CV_2116 resides in the fourth of these elements. Analysis of the putative operon in which CV_2116 resides indicates that CV_2116 might be a component of the bacteriophage tail-like assembly that occurs in C. violaceum.

A Convair 990 (CV-990) was used as a Landing Systems Research Aircraft (LSRA) at NASA's Dryden Flight Research Center, Edwards, California, to test space shuttle landing gear and braking systems as part of NASA's effort to upgrade and improve space shuttle capabilities. The first flight at Dryden of the CV-990 with shuttle test components occurred in April 1993, and tests continued into August 1995, when this photo shows a test of the shuttle tires. The purpose of this series of tests was to determine the performance parameters and failure limits of the tires. This particular landing was on the dry lakebed at Edwards, but other tests occurred on the main runway there. The CV-990, built in 1962 by the Convair Division of General Dynamics Corp., Ft. Worth, Texas, served as a research aircraft at Ames Research Center, Moffett Field, California, before it came to Dryden.

CV-Muzar - The Virtual Community Environment that Uses Multiagent Systems for Formation of Groups  

NASA Astrophysics Data System (ADS)

The purpose of this chapter is to present two agents' societies responsible for group formation (sub-communities) in CV-Muzar (Augusto Ruschi Zoobotanical Museum Virtual Community of the University of Passo Fundo). These societies are integrated to execute a data mining classification process. The first society is a static society that intends preprocessing data, investigating the information about groups in the CV-Muzar. The second society is a dynamical society that will make a classification process by analyzing the existing groups and look for participants that have common subjects in order to constitute a sub-community. The formation of sub-communities is a new functionality within the CV-Muzar that intends to bring the participants together according to two scopes: interest similarity and knowledge complementarities.

The Ningqiang meteorite - Classification and petrology of an anomalous CV chondrite  

NASA Astrophysics Data System (ADS)

Ningqiang is an anomalous CV chondrite (oxidized subgroup) containing a high abundance of aggregational inclusions (13.7 vol pct) and low abundances of refractory inclusions (1.0 + 1.0 or - 0.5 vol pct) and bulk refractory lithophiles (about 0.82 x CV). Ningqiang may have agglomerated after most refractory inclusions at the nebular midplane had already been incorporated into other objects. Coarse-grained rims surround only about 5 percent of Ningqiang chondrules, compared to about 50 percent in normal CV chondrites. Aggregational inclusions appear to have formed by incipient melting of fine-grained aggregates at relatively low temperatures in the solar nebula, possibly by the mechanism responsible for chondrule formation.

An amoeboid olivine inclusion (AOI) in CK3 NWA 1559, comparison to AOIs in CV3 Allende, and the origin of AOIs in CK and CV chondrites  

NASA Astrophysics Data System (ADS)

An amoeboid olivine inclusion in CK3 NWA 1559 (0.54 × 1.3 mm) consists of a diopside-rich interior (approximately 35 vol%) and an olivine-rich rim (approximately 65 vol%). It is the first AOI to be described in CK chondrites; the apparent paucity of these inclusions is due to extensive parent-body recrystallization. The AOI interior contains irregular 3-15 ?m-sized Al-bearing diopside grains (approximately 70 vol%), 2-20 ?m-sized pores (approximately 30 vol%), and traces of approximately 2 ?m plagioclase grains. The 75-160 ?m-thick rim contains 20-130 ?m-sized ferroan olivine grains, some with 120º triple junctions. A few coarse (25-50 ?m-sized) patches of plagioclase with 2-18 ?m-thick diopside rinds occur in several places just beneath the rim. The occurrence of olivine rims around AOI-1 and around many AOIs in CV3 Allende suggests that CK and CV AOIs formed by the acquisition of porous forsteritic rims around fine-grained, rimless CAIs that consisted of diopside, anorthite, melilite, and spinel. Individual AOIs in carbonaceous chondrites may have formed after transient heating events melted their olivine rims as well as portions of the underlying interiors. In AOI-1, coarse plagioclase grains with diopside rinds crystallized immediately below the olivine rim. Secondary parent-body alteration transformed forsterite in the rims of CV and CK AOIs into more-ferroan olivine. Some of the abundant pores in the interior of AOI-1 may have formed during aqueous alteration after fine-grained melilite and anorthite were leached out. Chondrite groups with large chondrules tend to have large AOIs. AOIs that formed in dust-rich nebular regions (where CV and CK chondrites later accreted) tend to be larger than AOIs from less-dusty regions.

MIL 090001 is a large (greater than 6 kg) CV chondrite from the reduced subgroup (CV(sub red)) that was recovered during the 2009-2010 ANSMET field season [1]. The CV(sub red) subgroup meteorites retain primitive characteristics and have escaped the Na and Fe meta-somatism that affected the oxidized (CV(sub ox)) subgroups. MIL 090001 is, however, reported to be altered [1], and thus a major objective of this study is to characterize its mineralogy and petrography and the extent of the alteration.

New parameter extraction method based on split C-V measurements in FDSOI MOSFETs  

NASA Astrophysics Data System (ADS)

A new parameter extraction methodology based on split C-V is proposed for FDSOI MOS devices. To this end, a detailed capacitance theoretical analysis is first conducted emphasizing the usefulness of the Maserjian function. Split C-V measurements carried out on various FDSOI CMOS technologies show that the Maserjian function exhibits a power law dependence with inversion charge as ?Qi-2 whatever the carrier type and gate oxide thickness. This feature enables to confirm the validity of a two-parameter simple capacitance model and allows for a reliable MOSFET parameter extraction in FDSOI devices.

Using CV-GLUE procedure in analysis of wetland model predictive uncertainty.  

PubMed

This study develops a procedure that is related to Generalized Likelihood Uncertainty Estimation (GLUE), called the CV-GLUE procedure, for assessing the predictive uncertainty that is associated with different model structures with varying degrees of complexity. The proposed procedure comprises model calibration, validation, and predictive uncertainty estimation in terms of a characteristic coefficient of variation (characteristic CV). The procedure first performed two-stage Monte-Carlo simulations to ensure predictive accuracy by obtaining behavior parameter sets, and then the estimation of CV-values of the model outcomes, which represent the predictive uncertainties for a model structure of interest with its associated behavior parameter sets. Three commonly used wetland models (the first-order K-C* model, the plug flow with dispersion model, and the Wetland Water Quality Model; WWQM) were compared based on data that were collected from a free water surface constructed wetland with paddy cultivation in Taipei, Taiwan. The results show that the first-order K-C* model, which is simpler than the other two models, has greater predictive uncertainty. This finding shows that predictive uncertainty does not necessarily increase with the complexity of the model structure because in this case, the more simplistic representation (first-order K-C* model) of reality results in a higher uncertainty in the prediction made by the model. The CV-GLUE procedure is suggested to be a useful tool not only for designing constructed wetlands but also for other aspects of environmental management. PMID:24726969

Stable expression of anti-HPV 16 E7-ribozyme in CV-1 cell lines.  

PubMed

The HPV16 (human papilloma virus type 16) E7 gene product, an oncoprotein, has been considered to be involved in the pathogenesis of anogenital cancer, particularly of cervical cancer. In order to evaluate the effect of suppression of the expression of the E7 gene in CV-1 cells by ribozyme, Rz523 with a transacting ribozyme targeted to the E7 RNA and two processing ribozyme genes at the 5' and 3' flank was cloned into the eukaryotic expression plasmid pREP9 under the control of RSV-LTR promoter. The resultant plasmid pRSV-Rz523 was transfected into CV-1 cells by calcium phosphate coprecipitation. The expression of the ribozyme in G418-resistant cells was detected by dot-blot hybridization. Ribozymes stably expressed in the CV-1 cells were at a level of 9.0 pmol per 10(6) cells, in which the active ribozyme molecules were more than 50 fmol per 10(6) cells. The result of RNase protection assay showed that the steady-state level of the E7 RNA fragment in CV-1 cell lines was significantly reduced by about 90% in ribozyme-expressing cells. In contrast, the antisense control plasmid pRSV-AE7 only exhibited about 20%. This result implicated the possibility of reversing the malignant phenotype of cervical cancer by means of suppressing the expression of the E7 gene with ribozyme. PMID:9187492

Galaxy and Mass Assembly (GAMA): the GAMA galaxy group catalogue (G3Cv1)  

NASA Astrophysics Data System (ADS)

Using the complete Galaxy and Mass Assembly I (GAMA-I) survey covering ˜142 deg2 to rAB= 19.4, of which ˜47 deg2 is to rAB= 19.8, we create the GAMA-I galaxy group catalogue (G3Cv1), generated using a friends-of-friends (FoF) based grouping algorithm. Our algorithm has been tested extensively on one family of mock GAMA lightcones, constructed from ? cold dark matter N-body simulations populated with semi-analytic galaxies. Recovered group properties are robust to the effects of interlopers and are median unbiased in the most important respects. G3Cv1 contains 14 388 galaxy groups (with multiplicity ?2), including 44 186 galaxies out of a possible 110 192 galaxies, implying ˜40 per cent of all galaxies are assigned to a group. The similarities of the mock group catalogues and G3Cv1 are multiple: global characteristics are in general well recovered. However, we do find a noticeable deficit in the number of high multiplicity groups in GAMA compared to the mocks. Additionally, despite exceptionally good local spatial completeness, G3Cv1 contains significantly fewer compact groups with five or more members, this effect becoming most evident for high multiplicity systems. These two differences are most likely due to limitations in the physics included of the current GAMA lightcone mock.

Formation of biphenyl and dibenzofuran phytoalexins in the transition zones of fire blight-infected stems of Malus domestica cv. 'Holsteiner Cox' and Pyrus communis cv. 'Conference'.  

PubMed

In the rosaceous subtribe Pyrinae (formerly subfamily Maloideae), pathogen attack leads to formation of biphenyls and dibenzofurans. Accumulation of these phytoalexins was studied in greenhouse-grown grafted shoots of Malus domestica cv. 'Holsteiner Cox' and Pyrus communis cv. 'Conference' after inoculation with the fire blight bacterium, Erwinia amylovora. No phytoalexins were found in leaves. However, both classes of defence compounds were detected in the transition zone of stems. The flanking stem segments above and below this zone, which were necrotic and healthy, respectively, were devoid of detectable phytoalexins. The transition zone of apple stems contained the biphenyls 3-hydroxy-5-methoxyaucuparin, aucuparin, noraucuparin and 2'-hydroxyaucuparin and the dibenzofurans eriobofuran and noreriobofuran. In pear, aucuparin, 2'-hydroxyaucuparin, noreriobofuran and in addition 3,4,5-trimethoxybiphenyl were detected. The total phytoalexin content in the transition zone of pear was 25 times lower than that in apple. Leaves and stems of mock-inoculated apple and pear shoots lacked phytoalexins. A number of biphenyls and dibenzofurans were tested for their in vitro antibacterial activity against some Erwinia amylovora strains. The most efficient compound was 3,5-dihydroxybiphenyl (MIC=115 ?g/ml), the immediate product of biphenyl synthase which initiates phytoalexin biosynthesis. PMID:22377689

Fayalitic olivine in CV3 chondrite matrix and dark inclusions: A nebular origin  

NASA Astrophysics Data System (ADS)

Fayalitic olivine (Fa>32) is the major component of the matrices and Dark Inclusions (DI) of CV3 and other unequilibrated chondrites. It occurs most commonly as rims, veins and halos in and around chondrule silicates in the Allende-type (CV3OxA) chondrites and to a much lesser extent in the reduced (CV3R) and Bali-type (CV3OxB) chondrites. The olivines have distinctive platy, tabular and lath- or irregular-shaped crystals, with the ratio the two types varying widely. In CV3OxB chondrites, matrix fayalitic olivines range up to Fa99.9, whereas in the other CV3 chondrites the range is much smaller. The platy and tabular anisotropic forms of the fayalitic olivines strongly suggest growth from a vapor and the nature of occurrences suggests that CV3 matrices are unequilibrated mixtures of nebular materials. We argue that the parent body hydration/dehydration model has numerous inconsistencies that make this hypothesis highly unlikely. These include: (1) There is no direct evidence linking fayalitic olivine to precursor phyllosilicates. (2) Dehydration of phyllosilicates cannot explain the wide range of morphologies of the fayalitic olivines. (3) Fayalitic olivine clearly predates the formation of the hydrous phases in CV3 chondrites and is one of the phases that breaks down to form phyllosilicates (Keller et al., 1994). (4) The unequilibrated nature of the matrix, including fine scale zoning in 10=B5-sized fayalitic olivine crystals, would not survive the parent body metamorphism required in the dehydration model. (5) A DI in the Ningqiang chondrite contains fayalitic olivine rimmed by glassy and microcrystalline material (Zolensky et al., 1997), which probably formed by radiation damage. This indicates that the fayalitic olivine was exposed to solar radiation in a nebular setting. (6) Some Allende chondrules contain unaltered primary, anhydrous glassy mesostasis in contact with the host matrix (e.g., Ikeda and Kimura, 1995). Chondrule mesostases would not have survived parent body hydration without becoming hydrated and would probably not survive the metamorphic heating required in the dehydration scenario. (7) Single platy and barrel-shaped crystals of fayalitic olivine are present in accretionary rims in CAIs (MacPherson and Davis, 1997), which developed in the nebula. (8) Matrix lumps completely encased in chondrules in ordinary chondrites contain mainly fayalitic olivine (Scott et al., 1984), indicating a nebular origin. (9) Oxygen isotopic compositions of Allende matrix and DIs strongly indicate little or no hydration for Allende and its components (Clayton, 1997). We favor a nebular vaporization/recondensation model in which vaporization of chondritic dust produced a fayalite-rich vapor, followed by formation of the fayalitic olivine by direct recondensation from the vapor, epitactic growth on surfaces of existing forsterite and enstatite in chondrules, and replacement of existing forsterite and enstatite by gas-solid exchange.

The influence of Peronospora tabacina Adam upon the growth rhythm of Nicotiana tabacum cv. Samsun.  

PubMed

The cinematographic method was used for studying the changes of the growth rhythm of the leaves in Nicotiana tabacum cv. Samsun after the inoculation with Peronospora tabacina Adam. The leaves were screened only at the maturing phase when displaying characteristic disturbances of the growth rhythm. The leaves of a healthy plant show a regular growth rhythm, with regular amplitudes of growth spirals and growth rate. The growth spiral increments are elongated regular and even up to the mature stage of the leaf. In Nicotiana tabacum cv. Samsun the original regular rhythm was kept for 130 hrs. after the infection with the conidia of Peronospora tabacina Adam. When the first symptoms of the disease appeared on an inoculated leaf (approximately after 20 hrs.), fructification of the mould occurred, the growth rhythm was retarded and, after the necrotization of spots, the leaf died away.

Heavily metamorphosed clasts from the CV chondrite breccias Mokoia and Yamato-86009  

NASA Astrophysics Data System (ADS)

Abstract- Metamorphosed clasts in the CV carbonaceous chondrite breccias Mokoia and Yamato-86009 (Y-86009) are coarse-grained, granular, polymineralic rocks composed of Ca-bearing (up to 0.6 wt% CaO) ferroan olivine (Fa34-39), ferroan Al-diopside (Fs9-13Wo47-50, approximately 2-7 wt% Al2O3), plagioclase (An37-84Ab63-17), Cr-spinel (Cr/(Cr + Al) = 0.19-0.45, Fe/(Fe + Mg) = 0.60-0.79), nepheline, pyrrhotite, pentlandite, Ca-phosphate, and rare grains of Ni-rich taenite; low-Ca pyroxene is absent. Most clasts have triple junctions between silicate grains, indicative of prolonged thermal annealing. Based on the olivine-spinel and pyroxene thermometry, the estimated metamorphic temperature recorded by the clasts is approximately 1100 K. Few clasts experienced thermal metamorphism to a lower degree and preserved chondrule-like textures. The Mokoia and Y-86009 clasts are mineralogically unique and different from metamorphosed chondrites of known groups (H, L, LL, R, EH, EL, CO, CK) and primitive achondrites (acapulcoites, brachinites, lodranites). On a three-isotope oxygen diagram, compositions of olivine in the clasts plot along carbonaceous chondrite anhydrous mineral line and the Allende mass-fractionation line, and overlap with those of the CV chondrule olivines; the ?17O values of the clasts range from about -4.3‰ to -3.0‰. We suggest that the clasts represent fragments of the CV-like material that experienced metasomatic alteration, high-temperature metamorphism, and possibly melting in the interior of the CV parent asteroid. The lack of low-Ca pyroxene in the clasts could be due to its replacement by ferroan olivine during iron-alkali metasomatic alteration or by high-Ca ferroan pyroxene during melting under oxidizing conditions.

Effectiveness and tolerability of CV-3988, a selective PAF antagonist, after intravenous administration to man.  

PubMed Central

1. The efficacy and tolerability of CV-3988, a selective PAF antagonist with structural analogies with PAF, were studied after intravenous infusion in man. 2. The compound, in doses from 750 to 2,000 micrograms kg-1, significantly reduced platelet sensitivity for PAF. The threshold aggregating concentration (TAC) of PAF, expressed in % of the mean predosing value, increased in a dose dependent manner reaching 356 +/- 162% of the basal TAC at the end and 266 +/- 123% of the basal TAC 4 h after infusion of the highest dose. The TAC of PAF returned to the basal value within 24 h after the end of the infusion. 3. CV-3988 did not cause major side effects nor changes in blood pressure, pulse and respiratory rate. However, small but clinically insignificant changes in plasma haemoglobin and serum haptoglobin were seen at the end and 4 h after the end of the infusion, indicating a slight haemolysis. 4. Our results indicate that, when adequate infusion volumes and infusion rates are used, CV-3988 can safely be administered to man and should be useful in elucidating the role of PAF in disease.

Umbilical reconstruction using a modified inverted C-V flap with conjoint flaps.  

PubMed

The umbilicus is an important aesthetic feature of the abdomen. Because of its location, the umbilicus can be injured after abdominal surgical procedures. Various methods have been devised to reconstruct the umbilicus by using local flaps, purse-string sutures, or a cartilage graft, but there are no ideal methods. The authors have created a modified inverted C-V flap with conjoint flaps. A 10-year-old boy presented with deformed umbilicus because he had undergone surgical correction of an omphalocele. The drawback of the traditional C-V flap method is the transverse long abdominal scar because of the long length of the V flap. However, by using two conjoint flaps at the superior part of the C-V flap, the length of V flap can be more short and the umbilical wall can be reconstructed by rotation of two conjoint flaps. It is also good for making a sinusoidal pocket and it makes the umbilicus deeper and more natural-looking. After the operation, there were no complications like flap necrosis, infection, haematoma, and so on. The patient was satisfied with the results The patient had a more attractive umbilicus than the one with the other previous technique. This new method makes a natural-looking umbilicus with less of a transverse scar and an adequate sinusoidal pocket and umbilical wall. PMID:23829506

In this paper we present an approach to teaching image processing and pattern recognition with the use of the OpenCV library. Image processing, pattern recognition and computer vision are important branches of science and apply to tasks ranging from critical, involving medical diagnostics, to everyday tasks including art and entertainment purposes. It is therefore crucial to provide students of image processing and pattern recognition with the most up-to-date solutions available. In the Institute of Electronics at the Technical University of Lodz we facilitate the teaching process in this subject with the OpenCV library, which is an open-source set of classes, functions and procedures that can be used in programming efficient and innovative algorithms for various purposes. The topics of student projects completed with the help of the OpenCV library range from automatic correction of image quality parameters or creation of panoramic images from video to pedestrian tracking in surveillance camera video sequences or head-movement-based mouse cursor control for the motorically impaired.

This study found that the above constituents killed H. nana or reduced their spontaneous movements (oscillation/peristalsis). However, the above constituents at various concentrations demonstrated no larvicidal effect or ability to halt spontaneous parasite movement for 72 h against A. simplex, respectively. In addition, according to an assay of cestocidal activity against H. nana and nematocidal activity against A. simplex, we found that the above compounds showed greater lethal efficacy on H. nana than against A. simplex. Further investigation showed that these above constituents have effects against peroxyl radicals under cestocidal effect. Together, these findings suggest that these constituents of Nelumbo nucifera Gaertn. cv. Rosa-plena might be used as anthelmintic agents against H. nana.

Together, these findings suggest that these constituents of Nelumbo nucifera Gaertn. cv. Rosa-plena might be used as anthelmintic agents against H. nana. PMID:24583851

Fayalite in the Vigarano CV3 carbonaceous chondrite: Occurrences, formation age and conditions  

NASA Astrophysics Data System (ADS)

We have performed petrographic characterization, 53Mn- 53Cr age determination and thermodynamic stability evaluations of fayalite in Vigarano meteorite that belongs to the reduced subgroup of CV3 chondrites. Vigarano is a breccia consisting of clasts which are separate chondrules surrounded by olivine-rich fine-grained materials. Four out of twenty three explored clasts contain fayalites that represent materials of the Bali-like oxidized subgroup of CV3 chondrites. The fayalites (Fa > 80 ) with grain sizes typically < 20 µm occurs in veins that extend from chondrules into the fine-grained materials. The fayalite commonly coexists with troilite and/or magnetite. The fayalite-bearing veins terminate at the boundaries of clasts. No evidence of strong impact enough to make melt veins is found in materials adjacent to the veins. These observations suggest that the fayalite-bearing veins in the Bali-like clasts formed through aqueous alteration in an asteroid prior to fragmentation and re-accretion to the Vigarano parent body. In saponite-rich fine-grained materials, we also found troilite-magnetite veins, which are similar to the fayalite-bearing veins in morphology. Morphological evidences and thermochemical equilibrium calculations suggest that fayalite replaced magnetite, and that replacement occurred at temperatures < 200 °C and low water/rock mass ratios from 0.07 to 0.18, which represent aqueous to metamorphic transition. Fayalite grains typically show iron-magnesium zoning (fayalite content decreases towards the grain edges). Based on equilibrium models, this zoning may have occurred at increasing temperature. The observed initial ratio of ( 53Mn/ 55Mn) 0 = (2.3 ± 0.5) × 10 - 6 suggests that fayalite formed ~ 5 Ma before the timing when the Mn-Cr system was closed in angrite NWA 4801 and has an absolute age of ~ 4563 ± 1 Ma. The age of fayalite is identical within errors to that in Mokoia and Kaba CV3 chondrites, which belong to the Bali-like oxidized subgroup. The identical age implies that aqueous alteration occurred at the same time in parent asteroids of Bali-like subgroup materials. These fayalite-bearing materials may have been derived from a single CV3 asteroid or from separate CV3 asteroids where aqueous alteration simultaneously occurred.

Secondary Mineralization of Components in CV3 Chondrites: Nebular and Asteroidal Models  

NASA Astrophysics Data System (ADS)

Our review of mineralogical variations among CV3 chondrites suggests that all components, chondrules, matrices, and CAIs, were affected by various degrees of secondary mineralization. Chondrules and CAIs are rimmed with fayalitic olivine [1, 2]; metal in all components is oxidized and sulfidized to magnetite, Ni-rich metal and sulfides [3]; silicates in all components are aqueously altered to phyllosilicates [4]; and nepheline, sodalite, wollastonite, and hedenbergite replace primary minerals in CAIs [5]. In those CV3s with altered CAIs, nepheline etc. are also present in chondrule mesostases [6] and in matrices [7]. Correlated occurrences of secondary minerals indicate that they have related origins. CV3 chondrites can be divided into three kinds according to their secondary features. Reduced CV3s (e.g., Efremovka) lack magnetite [8] and show minimal secondary features. Oxidized CV3s [8] generally show all features: those like Mokoia contain minor fayalitic rims, nepheline, etc, whereas those like Allende lack phyllosilicates but contain well developed fayalite rims and abundant nepheline, etc. Allende-like CV3 chondrites also contain abundant plate-like matrix olivine (Fa(sub)45-55). Similarities in chemistry and O isotopic composition and petrographic observations suggest that fayalitic rims and plate-like matrix olivine have related origins [1, 9]. The presence of secondary minerals in all components implies that alteration postdated component formation. The absence of secondary minerals in reduced CV3s indicates that CV3 oxidized formed from CV3 reduced-like material. Oxidized and reduced materials coexist in some breccias indicating a common parent asteroid. Nebular origins are widely accepted for most secondary features. To form fayalitic rims and matrix , Palme and colleagues [10, 11] suggest that chondritic components were briefly exposed to a hot (>1500 K), highly oxidizing nebula with H2O/H2 to about 1. Such an environment could have resulted from vaporization after >1000-fold dust/gas enrichment [11]. Fe-rich olivine will not condense until most Mg has condensed into forsterite [11]. The steep compositional gradients between adjacent fayalite and forsterite limit the duration of fayalite condensation to a period of several hours [2]. There are several inconsistencies in this late-stage evaporation-condensation model. Fayalitic rims occur inside chondrules and formed by alteration, not by condensation. Forsterite and enstatite grains that supposedly condensed from the nebula are absent on chondrule rims and in chondrites. Magnetite, Ni-rich metal and sulfides are present inside matrix olivine, inconsistent with equilibrium calculations. I-Xe data suggest that sodalite formation in Allende lasted for about 10 Myr, which is inconsistent with a nebular origin [12]. Asteroidal alteration is favored for magnetite [3] and required for most phyllosilicates [4]. Asteroidal formation of fayalite [13] was rejected [2], partly because hydrous minerals are absent in Allende. We suggest that Allende-like CV3 chondrites may have formed in an asteroid by aqueous alteration and dehydration; see Krot et al. [this volume] for details. Higher Na and K concentrations in oxidized CV3 chondrites are not inconsistent with asteroidal alteration, as CM2 chondrites show similar heterogeneities.

Cardiac versus vascular effects of a new dihydropyridine derivative, CV-4093. In vitro comparison with other calcium antagonists.  

PubMed

The effects of CV-4093, a new dihydropyridine derivative, on isolated cardiovascular tissues were compared with those of several dihydropyridine and non-dihydropyridine calcium antagonists. CV-4093 effectively inhibited the contractions induced in canine femoral arteries by high [K+]0 and Bay K 8644, but incompletely relaxed those induced by norepinephrine. CV-4093, 10(-6) M, abolished the electrically induced slow action potentials in guinea-pig papillary muscles partially depolarized by 25 mM K+ solution and attenuated those induced by isoproterenol, histamine and Bay K 8644. The rank order of potency of dihydropyridine and non-dihydropyridine calcium antagonists in canine femoral arteries and veins precontracted with 120 mM [K+]0 was as follows: nisoldipine greater than nicardipine greater than or equal to nifedipine greater than or equal to CV-4093 greater than verapamil greater than or equal to diltiazem. Nisoldipine was the most potent and CV-4093 was the least potent among these drugs in terms of negative inotropic effect in normally polarized papillary muscles and negative chronotropic effect in right atria of guinea pigs. The rank order of potency for these cardiodepressant actions was nisoldipine greater than or equal to nifedipine greater than nicardipine greater than verapamil greater than diltiazem greater than or equal to CV-4093. The duration of action potential in guinea-pig papillary muscles was shortened by nisoldipine and nifedipine, unchanged by nicardipine and CV-4093 and was slightly prolonged by verapamil and diltiazem. These results suggest that CV-4093 is a calcium antagonist with a highly selective vascular effect and little cardiodepressant action, and could be of value for the treatment of hypertension.

mdx(?cv) mice manifest more severe muscle dysfunction and diaphragm force deficits than do mdx Mice.  

PubMed

Duchenne muscular dystrophy (DMD) is characterized by progressive skeletal muscle dysfunction leading to premature death by the third decade of life. The mdx mouse, the most widely used animal model of DMD, has been extremely useful to study disease mechanisms and to screen new therapeutics. However, unlike patients with DMD, mdx mice have a very mild motor function deficit, posing significant limitations for its use as a platform to assess the impact of treatments on motor function. It has been suggested that an mdx variant, the mdx(5cv) mouse, might be more severely affected. Here, we compared the motor activity, histopathology, and individual muscle force measurements of mdx and mdx(?cv) mice. Our study revealed that mdx(?cv) mice showed more severe exercise-induced fatigue, Rotarod performance deficits, and gait anomalies than mdx mice and that these deficits began at a younger age. Muscle force studies showed more severe strength deficits in the diaphragm of mdx(?cv) mice compared to mdx mice, but similar force generation in the extensor digitorum longus. Muscle histology was similar between the two strains. Differences in genetic background (genetic modifiers) probably account for these functional differences between mdx strains. Overall, our findings indicate that the mdx and mdx(?cv) mouse models of DMD are not interchangeable and identify the mdx(?cv) mouse as a valuable platform for preclinical studies that require assessment of muscle function in live animals.

Axillary bud expiants from South Pacific (Solomon Islands) taro, Colocasia esculenta var. esculenta cv. Akalomamale (Araceae) cultured on a modified Murashige-Skoog medium containing 1 mg NAA 1(-1) and TE formed callus and produced multiple plantlets. Explants died if NAA was present at levels lower than 0.1 mg 1(-1). BA was not required and may have been inhibitory. Plantlets developed faster and became larger following transfer to a hormone-free medium two weeks after the start of culture. Fully grown plants were established in a potting mix and are growing well in a greenhouse. PMID:24226709

Carrier Density Profiling of Ultra-Shallow Junction Layers Through Corrected C-V Plotting  

SciTech Connect

The aim of this report is to present and justify a new approach for carrier density profiling in ultra-shallow junction (USJ) layer. This new approach is based on a capacitance measurement model, which takes series impedance, shunt resistance and the presence of a boron skin on the USJ layer into account. It allows us to extract the depletion layer capacitances in the USJ layer from C-V plotting more accurately and hence to obtain better carrier density profiles. Based on this new approach the carrier density profiles of different USJ layers with and without halo-style implants are obtained and discussed.

The light curve of CV Serpentis, the sometimes-eclipsing Wolf-Rayet star  

NASA Technical Reports Server (NTRS)

New photoelectric observations of the B-magnitude of CV Ser made in 1973 and 1974 show no clear evidence of an eclipse, but they establish night-to-night variability of several percent, a systematic brightness change of 0.035 mag during a portion of the single orbit observed in 1973, and irregular flaring in 1974. We made iris photometer measurements of Harvard patrol plates taken between 1905 June and 1953 July, and find no evidence of a very deep eclipse such as observed by Hjellming and Hiltner. We present several new light curves and discuss then in the light of the recent results of Cowley et al.

Dark inclusions in Allende, Leoville, and Vigarano - Evidence for nebular oxidation of CV3 constituents  

NASA Astrophysics Data System (ADS)

The origin and the history of dark inclusions (DIs) are investigated using petrologic, chemical, and oxygen isotopic data on ten DI samples from Allende, Leoville, and Vigarano. These data indicate that the DIs of the Leoville and Vigarano are closely similar to those of Allende. The inclusions appear to be fragments of CV3 parent bodies which were processed to different degrees prior to their incorporation as clasts into the Allende, Leoville, and Vigarano chondrites. The processing homogenized the olivine compositions, presumably through heating, and also involved oxygen exchange with O-16-poorer surroundings.

Ophthalmic results in patients with macroprolactinomas treated with a new prolactin inhibitor CV 205-502.  

PubMed Central

Macroprolactinomas are pituitary tumours which have been effectively treated medically since the introduction of bromocriptine. The visual function of 13 patients treated with a new prolactin (PRL) inhibitor CV 205-502 (Sandoz Basle), a potent and selective dopamine D2 receptor agonist, was evaluated. This is the first detailed ophthalmic report of the use of this drug in macroprolactinomas. Patients were enrolled from June 1988 to July 1990 (mean follow up 30 months). Visual function including visual acuity, ocular pressure, and visual fields was regularly controlled. Visual fields (VF) were tested with Goldmann and automatic static perimetry (Vision Monitor). Treatment was globally effective. No modifications of the visual function were observed in nine patients (six normal, three previous VF losses after surgery). In four other patients, visual function dramatically improved (regression of a III paresis, one case; disappearance of a chiasmatic syndrome, three cases). A pituitary necrosis was observed in one case and successfully cured. CV 205-502 seems to be an effective and well tolerated treatment of macroprolactinomas. Images

Electroacupuncture Stimulation at CV12 Inhibits Gastric Motility via TRPV1 Receptor  

PubMed Central

Gastric dysmotility is one of the major pathophysiological factors in functional gastrointestinal disorders. Acupuncture, as one of the alternative approaches, is efficacious in the treatment of gastrointestinal motility disorders; however, the mechanism underlying its action is unclear. In the present study, we used both capsazepine, a TRPV1 antagonist, and TRPV1 knockout mice. Animals were divided into wild-type group (WT), capsazepine injection group (CZP, 0.5?mg/kg, i.p.), and TRPV1 knockout mice group (TRPV1?/?). Each of these three groups was divided into three subgroups, which were subjected to EA stimulation at acupoint Zhongwan (CV12) at a different intensity (1, 2, or 4?mA). We demonstrated that electroacupuncture at Zhongwan (CV12) markedly inhibited gastric motility at 2 and 4?mA in an intensity-dependent manner in wild-type mice. The inhibitory effect was also observed in capsazepine-injected and TRPV1?/? mice but was no longer intensity dependent, indicating that TRPV1 is partially involved in the electroacupuncture-mediated modulation of gastric motility.

Biochemical markers assisted screening of Fusarium wilt resistant Musa paradisiaca (L.) cv. puttabale micropropagated clones.  

PubMed

An efficient protocol was standardized for screening of panama wilt resistant Musa paradisiaca cv. Puttabale clones, an endemic cultivar of Karnataka, India. The synergistic effect of 6-benzyleaminopurine (2 to 6 mg/L) and thidiazuron (0.1 to 0.5 mg/L) on MS medium provoked multiple shoot induction from the excised meristem. An average of 30.10 +/- 5.95 shoots was produced per propagule at 4 mg/L 6-benzyleaminopurine and 0.3 mg/L thidiazuron concentrations. Elongation of shoots observed on 5 mg/L BAP augmented medium with a mean length of 8.38 +/- 0.30 shoots per propagule. For screening of disease resistant clones, multiple shoot buds were mutated with 0.4% ethyl-methane-sulfonate and cultured on MS medium supplemented with Fusarium oxysporum f. sp. cubense (FOC) culture filtrate (5-15%). Two month old co-cultivated secondary hardened plants were used for screening of disease resistance against FOC by the determination of biochemical markers such as total phenol, phenylalanine ammonia lyase, oxidative enzymes like peroxidase, polyphenol oxidase, catalase and PR-proteins like chitinase, beta-1-3 glucanase activities. The mutated clones of M. paradisiaca cv. Puttabale cultured on FOC culture filtrate showed significant increase in the levels of biochemical markers as an indicative of acquiring disease resistant characteristics to FOC wilt. PMID:23898552

THE RELATIONSHIP QUESTIONNAIRE-CLINICAL VERSION (RQ-CV): INTRODUCING A PROFOUNDLY-DISTRUSTFUL ATTACHMENT STYLE  

PubMed Central

Cost-efficient prenatal assessments are needed that have the potential to identify those at risk for parent/infant relational problems. With this goal in mind, an additional attachment style description was added to the Relationship Questionnaire (Bartholomew & Horowitz, 1991), an established self-report attachment measure, to create the Relationship Questionnaire: Clinical Version (RQ-CV). The additional description represents a profoundly-distrustful attachment style: “I think it's a mistake to trust other people. Everyone's looking out for themselves, so the sooner you learn not to expect anything from anybody else the better.” The RQ-CV was applied to a sample of 44 low-income mothers who had participated in a previous study of the impact of family risk factors on infant development. After first controlling for demographic risk factors and for other insecure adult attachment styles, mother's profound-distrust was associated with three independent assessments of the quality of maternal interactions with the infant assessed 20 years earlier. In particular, profound-distrust was related to more hostile, intrusive, and negative behaviors toward the infant. The results are discussed within the framework of attachment theory.

Metabolism of Tritiated Gibberellin A(9) by Shoots of Dark-grown Dwarf Pea, cv. Meteor.  

PubMed

Tritium-labeled gibberellin A(9) ((3)H-GA(9)) was metabolized by etiolated shoots of dwarf pea (Pisum sativum cv. Meteor) to GA(20), GA(10), 2,3-dihydro-GA(31), and a number of highly polar, acidic GA-like substances. Identifications were made by gasliquid radiochromatography and combined gas chromatography-mass spectrometry. Kinetic studies showed that GA(30) and 2,3-dihydro-GA(31) were produced within 5 hours following (3)H-GA(9) application to pea shoots. The polar GA-like substances were produced between 5 and 10 hours after (3)H-GA(9) application. Levels of GA(10) increased with time, and since no GA(10) was produced during the purification procedures, GA(10) was, in all probability, produced from (3)H-GA(9) within the plant tissue. The radioactive interconversion products produced by pea from (3)H-GA(9) have chromatographic properties similar to biologically active GA-like substances present in etiolated shoots of dwarf pea. Large scale applications of (3)H-GA(9) with very low specific activity to etiolated pea shoots showed that the radioactivity of the interconversion products was correlated exactly with biological activity as assayed by dwarf rice (Oryza sativa cv. Tan-ginbozu). PMID:16658838

Multi-camera calibration based on openCV and multi-view registration  

NASA Astrophysics Data System (ADS)

For multi-camera calibration systems, a method based on OpenCV and multi-view registration combining calibration algorithm is proposed. First of all, using a Zhang's calibration plate (8X8 chessboard diagram) and a number of cameras (with three industrial-grade CCD) to be 9 group images shooting from different angles, using OpenCV to calibrate the parameters fast in the camera. Secondly, based on the corresponding relationship between each camera view, the computation of the rotation matrix and translation matrix is formulated as a constrained optimization problem. According to the Kuhn-Tucker theorem and the properties on the derivative of the matrix-valued function, the formulae of rotation matrix and translation matrix are deduced by using singular value decomposition algorithm. Afterwards an iterative method is utilized to get the entire coordinate transformation of pair-wise views, thus the precise multi-view registration can be conveniently achieved and then can get the relative positions in them(the camera outside the parameters).Experimental results show that the method is practical in multi-camera calibration .

Evidence for internally generated magnetic fields on the CV chondrite parent planetesimal  

NASA Astrophysics Data System (ADS)

It has long been known that some carbonaceous chondrites carry a stable natural remanent magnetization. The origin of this magnetization has been a longstanding mystery because it was in many cases acquired following accretion of the parent bodies. The spinning, orbiting parent body would have been unlikely to record the spatially and temporally variable magnetic fields associated with the early sun and the protoplanetary disk. On the other hand, the possibility of an internally generated dynamo field has been discounted due to the traditional assumption that chondrites are samples of undifferentiated bodies. We have conducted a paleomagnetic study on mutually oriented samples of Allende CV3 carbonaceous chondrite. We found that the fusion crust is magnetized in a different direction from the interior, which constitutes a baked contact test demonstrating that the magnetization in the interior is preterrestrial. Our thermal demagnetization analyses demonstrate that most of the natural remanent magnetization is carried by pyrrhotite with a small contribution from magnetite and other phases. This confirms results from numerous previous investigators that the magnetization in Allende must have been acquired after accretion. A variety of petrologic and geochronometric suggest that thermal metamorphism to peak temperatures of 550- 600°C continued for millions of years afterward, consistent with our thermal demagnetization data. Other new geochemical datasets indicate that metallic cores had already formed in planetesimals by this time. Therefore, the magnetization Allende and other CV samples is naturally explained by an internal core dynamo on a partially differentiated parent body.

Structural analysis of the short length ribosomal DNA variant from Pisum sativum L. cv. Alaska.  

PubMed Central

The genomic clone, RRNpss1, representing the short ribosomal DNA length variant in Pisum sativum L. cv. Alaska, has been isolated and the 2859 bp intergenic spacer, along with the 25S rRNA 3' border and 18S rRNA 5' border, has been sequenced. The intergenic spacer contains nine tandem repeats, approximately 180 bp in length, which show greater than 80% sequence homology to each other. The RNA polymerase I transcription start site and a processing site, located 776 bp and 536 bp upstream of the 5' end of 18S rRNA, respectively, have been determined using S1 analysis. The region surrounding the +1 site shows strong homology between the positions -6 to +10 to the rDNA sites of initiation in radish, maize, and wheat. The sequence CATGCAAA is located 19 bp upstream of the site of initiation, and appears once within each subrepeat and twice more between the end of the subrepeat array and the site of initiation. A previously characterized HpaII site which shows developmental regulation of methylation is located 31 bp downstream of the site of initiation. Using RFLP linkage analysis, the short rDNA length variant of cv. Alaska is assigned to Chromosome 4 where it is genetically independent of the long rDNA length variant which is putatively assigned to Chromosome 7. Images

Gene ontology based characterization of expressed sequence tags (ESTs) of Brassica rapa cv. Osome.  

PubMed

Chinese cabbage (Brassica rapa) is widely recognized for its economic importance and contribution to human nutrition but abiotic and biotic stresses are main obstacle for its quality, nutritional status and production. In this study, 3,429 Express Sequence Tag (EST) sequences were generated from B. rapa cv. Osome cDNA library and the unique transcripts were classified functionally using a gene ontology (GO) hierarchy, Kyoto encyclopedia of genes and genomes (KEGG). KEGG orthology and the structural domain data were obtained from the biological database for stress related genes (SRG). EST datasets provided a wide outlook of functional characterization of B. rapa cv. Osome. In silico analysis revealed % 83 of ESTs to be well annotated towards reeds one dimensional concept. Clustering of ESTs returned 333 contigs and 2,446 singlets, giving a total of 3,284 putative unigene sequences. This dataset contained 1,017 EST sequences functionally annotated to stress responses and from which expression of randomly selected SRGs were analyzed against cold, salt, drought, ABA, water and PEG stresses. Most of the SRGs showed differentially expression against these stresses. Thus, the EST dataset is very important for discovering the potential genes related to stress resistance in Chinese cabbage, and can be of useful resources for genetic engineering of Brassica sp.

In Situ Measurement of Oxygen Isotope Compositions of Magnetite in the Allende CV3 Chondrite  

NASA Astrophysics Data System (ADS)

Magnetite is relatively abundant in the oxidized CV chondrites. This study was undertaken to examine possible origins in nebular or in parent-body processes. Magnetite in Allende has several distinct characteristics compared to that of the other CV chondrites. Unlike Mokoia and Vigarano, magnetite in Allende is almost exclusively found in chondrules, where it typically forms spherical nodules often associated with metal and/or sulfides. In addition, the Ni contents of metal in most CV chondrites seldom exceed 50 wt%, while in Allende nearly all of metal grains are Ni rich (64-71 wt% Ni [e.g., 1]), which we designate awaruite even though the Ni range is below that of awaruite. Rare kamacite grains are present in chondrules [2]. A few rare Allende nodules have euhedral to subhedral awaruite grains [e.g., 3]. Nodules of magnetite + sulfides, magnetite + metal, and metal + sulfide exhibit different textures implying that magnetite grains are not simply pseudomorphs of preexisting metal grains. Tiny magnetite grains (< 1 micrometer) are found in Ni-rich metal ; in turn, the host metal is surrounded by magnetite. The textural evidence is not sufficient to distinguish between a high temperature and a low temperature origin for the magnetite. Six magnetite nodules, which had relatively clean areas of ~ 25 micrometers diameter, from 4 Allende PO chondrules were selected for in situ oxygen isotope study using the UCLA Cameca ims 1270, a high resolution - high sensitivity ion microprobe. A ~0.3 nA primary Cs+ beam was defocused to a 20-25 micrometers spot and a field aperture inserted into the secondary ion beam to restrict the analyzed area to the central 10-12 micrometers of each nodule. Negative ions were collected at a mass resolving power of ~6500, sufficient to eliminate hydride interferences. A normal incidence electron gun was employed to compensate possible sample charging. To monitor the instrumental mass fractionation (-11.2+/-0.5 per mil/amu) analyses of terrestrial magnetite LP204a [4] were made interspersed amongst the chondrule analyses. Chondrule data corrected for mass fractionation and normalized to the SMOW scale are shown in Figure 1. Oxygen isotope ratios from inclusion and crack free regions in four magnetite nodules are tightly clustered below the terrestrial mass fractionation (TF) line and are distinct from oxygen isotope fields observed in magnetite from CI and Essebi chondrites [5] and from isolated grains in CI meteorites [6]. The data plot near the ^(16)O mixing line of refractory minerals in Allende (CCAM), but the spread in the ratios is too low relative to the precision of the measurements to define any linear trend for these samples. In 2 chondrules, magnetite nodules with cracks or Ni-Fe metal have very different oxygen compositions; they plot near the TF line at low delta^(18)O (-10 per mil). At this time, it is not clear if this difference could be due to a sputtering artifact, or if it reflects alteration or inclusion of another phase in these "magnetite" nodules. The question of the origin of CV magnetite has not yet been resolved. Data on additional samples including other CV chondrites will help clarify this point. References: [1] McSween H. Y.

Determination of the petrologic type of CV3 chondrites by Raman spectroscopy of included organic matter  

NASA Astrophysics Data System (ADS)

This paper reports the first reliable quantitative determination of the thermal metamorphism grade of a series of nine CV3 chondrites: Allende, Axtell, Bali, Mokoia, Grosnaja, Efremovka, Vigarano, Leoville, and Kaba. The maturity of the organic matter in matrix, determined by Raman spectroscopy, has been used as a powerful metamorphic tracer, independent of the mineralogical context and extent of aqueous alteration. This tracer has been used along with other metamorphic tracers such as Fe zoning in type-I chondrules of olivine phenocrysts, presolar grain abundance and noble gas abundance (bulk and P3 component). The study shows that the petrologic types determined earlier by Induced ThermoLuminescence were underestimated and suggests the following values: PT (Allende-Axtell) >3.6; PT (Bali-Mokoia-Grosnaja) ˜3.6; PT (Efremovka-Leoville-Vigarano) = 3.1-3.4; PT (Kaba) ˜3.1. The most commonly studied CV3, Allende, is also the most metamorphosed. Bali is a breccia containing clasts of different petrologic types. The attribution suggested by this study is that of clasts of the highest petrologic types, as pointed out by IOM maturity and noble gas bulk abundance. CV3 chondrites have complex asteroidal backgrounds, with various degrees of aqueous alteration and/or thermal metamorphism leading to complex mineralogical and petrologic patterns. (Fe,Mg) chemical zoning in olivine phenocrysts, on the borders of type I chondrules of porphyritic olivine- and pyroxene-rich textural types, has been found to correlate with the metamorphism grade. This suggests that chemical zoning in some chondrules, often interpreted as exchanges between chondrules and nebular gas, may well have an asteroidal origin. Furthermore, the compositional range of olivine matrix is controlled both by thermal metamorphism and aqueous alteration. This does not support evidence of a nebular origin and does not necessarily mirror the metamorphism grade through (Fe,Mg) equilibration. On the other hand, it may provide clues on the degree of aqueous alteration vs. thermal metamorphism and on the timing of both processes. In particular, Mokoia experienced significant aqueous alteration after the metamorphism peak, whereas Grosnaja, which has similar metamorphism grade, did not.

Chemical and physical studies of type 3 chondrites 12: The metamorphic history of CV chondrites and their components  

NASA Technical Reports Server (NTRS)

The induced thermoluminescence (TL) properties of 16 CV and CV-related chondrites, four CK chondrites and Renazzo (CR2) have been measured in order to investigate their metamorphic history. The petrographic, mineralogical and bulk compositional differences among the CV chondrites indicate that the TL sensitivity of the approximately 130 C TL peak is reflecting the abundance of ordered feldspar, especially in chondrule mesostasis, which in turn reflects parent-body metamorphism. The TL properties of 18 samples of homogenized Allende powder heated at a variety of times and temperatures, and cathodoluminescence mosaics of Axtell and Coolidge, showed results consistent with this conclusion. Five refractory inclusions from Allende, and separates from those inclusions, were also examined and yielded trends reflecting variations in mineralogy indicative of high peak temperatures (either metamorphic or igneous) and fairly rapid cooling. The CK chondrites are unique among metamorphosed chondrites in showing no detectable induced TL, which is consistent with literature data that suggests very unusual feldspar in these meteorites. Using TL sensitivity and several mineral systems and allowing for the differences in the oxidized and reduced subgroups, the CV and CV-related meteorites can be divided into petrologic types analogous to those of the ordinary and CO type 3 chondrites. Axtell, Kaba, Leoville, Bali, Arch and ALHA81003 are type 3.0-3.1, while ALH84018, Efremovka, Grosnaja, Allende and Vigarano are type 3.2-3.3 and Coolidge and Loongana 001 are type 3.8. Mokoia is probably a breccia with regions ranging in petrologic type from 3.0 to 3.2. Renazzo often plots at the end of the reduced and oxidized CV chondrite trends, even when those trends diverge, suggesting that in many respects it resembles the unmetamorphosed precursors of the CV chondrites. The low-petrographic types and low-TL peak temperatures of all samples, including the CV3.8 chondrites, indicates metamorphism in the stability field of low feldspar (i.e., less than 800 C) and a metamorphic history similar to that of the CO chondrites but unlike that of the ordinary chondrites.

C-V measurements of micron diameter metal-oxide-semiconductor capacitors using a scanning-electron-microscope-based nanoprobe  

SciTech Connect

The C-V electrical characterization of microstructures on a standard probe station is limited by the magnification of the imaging system and the precision of the probe manipulators. To overcome these limitations, we examine the combination of in situ electrical probing and a dual column scanning electron microscope/focused ion beam system. The imaging parameters and probing procedures are carefully chosen to reduce e-beam damage to the metal oxide semiconductor capacitor device under test. Estimation of shunt capacitance is critical when making femtofarad level measurements. C-V measurements of micron size metal-oxide-silicon capacitors are demonstrated.

Restriction fragment length polymorphism analysis, using peroxidase, O-methyltransferase, phenylalanine ammonia-lyase, and coniferyl alcohol dehydrogenase cDNAs isolated from Stylosanthes humilis, as probes, provided molecular evidence for the genetic origin of the naturally occuring allotetraploid genotype Stylosanthes hamata cv. Verano (2n = 4x = 40). Hybridization patterns strongly suggest that the likely progenitors of S. hamata cv. Verano were a diploid S. humilis (2n = 2x = 20) and a diploid S. hamata (2n = 2x = 20) species. PMID:18470174

Postharvest treatments with ethylene on Vitis vinifera (cv Sangiovese) grapes affect berry metabolism and wine composition.  

PubMed

Grapes (Vitis vinifera, cv Sangiovese), harvested at standard commercial maturity, were treated for 36 h with ethylene (ET, 1000 ppm) or air (control, CT) before vinification. The composition of the grapes, must and wine was different in the CT and ET samples. In the ET wine, higher concentrations of specific phenol compounds, belonging to the classes of flavonols, anthocyanins, flavan-3-ols, and stilbenes, were detected. ET induced a significant change in the wine aroma profile by increasing free volatile categories such as phenols and fatty acids, and reducing the content of carbonyl compounds and, in particular, of esters. Less pronounced differences between CT and ET wines were observed in terms of glycosidically-bound volatile compounds. The activity of pectin methyl esterase and ?-glucosidase was enhanced in ET-treated berry skins, suggesting that cell wall properties and changes in the hydrolytic activity are effective in modulating the composition of CT and ET wines.

Proliferation potential of 18-month-old callus of Ananas comosus L. cv. Moris.  

PubMed

Differential effect of plant growth regulators and additives in proliferation of 18-month-old calli of Ananas comosus L. cv. Moris were assessed in vitro. The proliferation of callus relied on the growth regulators and additives. Of the different auxins supplemented in the Murashige and Skoog (MS) media, 32.22 microM alpha-naphthaleneacetic acid (NAA) gave the highest mean fresh weight of callus (46.817 g). Medium supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D) was inferior to NAA, while b-naphthoxy acetic acid (BNOA) and p-chlorophenoxy acetic acid (4-CPA) were not effective in proliferating 18-months old callus. Addition of casein hydrolysate and coconut water to NAA supplemented medium showed better proliferation and production of callus. However, in terms of callus production, NAA at 32.22 microM was economically better. PMID:16493521

Factors affecting taste scores of early season seedless table grape cv. Mystery and Prime.  

PubMed

Table grapes of cv. Mystery and Prime were harvested from 10 farms in two growing areas of Israel over two seasons. The grapes were separated on the basis of sucrose solutions from 12 to 18%; soluble solids content (SSC), titratable acidity (TA), and pH were determined; and taste tests were conducted. SSC gave the best correlation with taste tests, and multiple regression of SSC, TA, and pH improved the correlation. There were both seasonal and regional differences in the measured maturity parameters. Lower TA and higher pH were found in grapes from the Jordan Valley. Volatiles were predominantly C(6) compounds hexanal and 2-hexanal, contributing a fresh aroma to the grapes. It is concluded that Mystery and Prime grapes have good organoleptic quality if harvested at SSC levels of >14%. PMID:11804527

In vitro selection of endosulfan-tolerant strains of Brassica compestris (cv. Brown Sarson).  

PubMed

Endosulfan tolerant lines of mustard (Brassica campestris cv. Brown Sarson) have been developed through tissue culture methods. Cotyledonary expiants excised from eight day old in vitro grown seedlings were used for inducing callus. Fast growing friable callus was then transferred to MS medium containing (0.1-2.0 ugl(-1)) endosulfan for selection. Five alternating exposures with and without endosulfan containing medium yielded an endosulfan tolerant cell line (ETL). The plants regenerated from ETL were found to tolerate three fold higher concentrations of endosulfan. Callus induced from randomly selected endosulfan tolerant regenerated plants were also tolerant to 3.0 ugl endosulfan, thereby, suggesting that tolerance has been acquired at the gene level.Biochemical investigation revealed higher levels of total free sugar, free amino acids, protein and activity of peroxidase in the tolerant cell line.

Screening of a functional polysaccharide from Zizyphus Jujuba cv. Jinsixiaozao and its property.  

PubMed

Chinese jujube has been used as a kind of Chinese medicinal herb for a long time. In this paper, the polysaccharides from Zizyphus Jujuba cv. Jinsixiaozao (ZSP), one of the major Chinese jujube varieties, were extracted and purified sequentially so that its water-soluble immunobiological fractions were screened. The crude ZSP was found to dramatically increase thymus and spleen indices in mice, enhance the proliferation of splenocytes and peritoneal macrophages, and have potential anti-complementary activity. Immunobiological tests indicated that two fractions of ZSP, coded ZSP3c and ZSP4b, were the main active components. ZSP3c was rich in pectin with a degree of esterification (DE) of 49%, which may be related to its stronger immunological activity. PMID:21539856

Biogenesis of volatile methyl esters in snake fruit (Salacca edulis, Reinw) cv. Pondoh.  

PubMed

The methyl esters of carboxylic acids are characteristic olfactory volatile compounds for the sweet aroma of snake fruit, (Salacca edulis, Reinw) cv. Pondoh. Although methanol was not detected as a volatile constituent, the crude enzymes showed activity to synthesize the methyl esters in the presence of acyl-CoA and methanol. Therefore, the biosynthetic origin of methanol was investigated, resulting in the detection of pectin methyl transferase activity in the flesh. This pectin methyl transferase activity increased during fruit maturation, in parallel with the level of methanol originating from hand-squeezed juice and with the methyl esters extracted from flesh of the fruit. Based on these results, the origin of methanol was confirmed to be the methyl esters of pectins. The crude enzyme also catalyzed the formation of methyl hexanoate, one of the esters of the fruit, in the presence of methyl pectins and hexanoyl-CoA that were used as precursors for a model reaction.

Complete bi-partite CV entanglement characterization via coveriance matrix measurement  

NASA Astrophysics Data System (ADS)

We report the first complete experimental reconstruction of the covariance matrix (CM) relative to a bi-partite continuous variable (CV) entangled state outing a non degenerate optical parametric oscillator (OPO) below threshold. The covariance matrix CM has been reconstructed following the method reported in V. D'Auria et al., J. Opt. B 7, S750 (2005). The two entangled beams (signal (a) and idler (b)) are produced by a by a continuous wave (CW) optical parametric oscillator (OPO) via type-II (same frequency but with orthogonal polarizations), phase matching and working below threshold. Our experimental setup makes use of a single homodyne detector and of a compact source of entangled beams. The quadratures values and other relevant quantities are reconstructed by quantum tomography, without making any a priori assumption on the state under evalutation.

Detection of unusual carotenoid esters in fresh mango (Mangifera indica L. cv. 'Kent').  

PubMed

The carotenoid pattern of mango cv. 'Kent' was investigated by LC-(APcI)MS analyses. In solvent extracts from the mesocarp an unusual carotenoid ester was identified as violaxanthin dibutyrate. For unequivocal identification of butyric acid by an independent method, total lipids were isolated by solvent extraction from the fruit flesh and analyzed by GC after saponification and subsequent methylation. Thus, evidence of butyric acid (1.6 area%) was provided. To the best of our knowledge, this is the first report on a xanthophyll dibutyrate in plants. Additionally, further carotenoid peaks were tentatively assigned to 9-cis-violaxanthin and neochrom or luteoxanthin, respectively, by their UV/vis and MS data of the saponified extracts.

Partial melting of the Allende (CV3) meteorite - Implications for origins of basaltic meteorites  

NASA Astrophysics Data System (ADS)

Eucrites and angrites are distinct types of basaltic meteorites whose origins are poorly known. Experiments in which samples of the Allende (CV3) carbonaceous chondrite were partially melted indicate that partial melts can resemble either eucrites or angrites, depending only on the oxygen fugacity. Melts are eucritic if this variable is below that of the iron-wuestite buffer or angritic if above it. With changing pressure, the graphite-oxygen redox reaction can produce oxygen fugacities that are above or below those of the iron-wuestite buffer. Therefore, a single, homogeneous, carbonaceous planetoid greater than 110 kilometers in radius could produce melts of drastically different composition, depending on the depth of melting.

The altitudinal variation of the contents of secondary metabolites in flowering heads of Matricaria chamomilla L. (Asteraceae) was assessed. Plants of M. chamomilla cultivar BONA were grown in nine experimental plots at altitudes between 590 and 2,230 m at Mount Patscherkofel near Innsbruck/Austria. The amounts of flavonoids and phenolic acids were quantified by HPLC/DAD. For both flavonoids and phenolic acids positive (r = 0.559 and 0.587) and statistically significant (both p < 0.001) correlations with the altitude of the growing site were observed. The results are compared to previous results on Arnica montana L. cv. ARBO. Moreover, various ecological factors, which change with the altitude of the growing site, are discussed as potential causes for the observed variation. PMID:18484542

Bioresorbable adhesion barrier for reducing the severity of postoperative cardiac adhesions: Focus on REPEL-CV®  

PubMed Central

Treatment of a number of congenital heart defects often necessitates staged surgical intervention. In addition, substantial improvements in postoperative cardiac care and more liberal use of biological valve substitutes have resulted in many adult patients surviving to become potential candidates for reoperations to repair or replace valves or to undergo additional revascularization procedures. In all these scenarios, surgeons are confronted with cardiac adhesions, leading to an increased surgical risk. Thus, bioresorbable adhesion barriers had become of increasing interest because they are easy to use, and safe and effective. This review focuses on the mechanisms by which REPEL-CV® prevents adhesive processes, as well as the development, design, and materials used, and also summarizes efficacy studies, clinical data, safety, and current role in therapy.

Unusual Dark Clasts in the Vigarano CV3 Chondrite: Record of Parent Body Process  

NASA Astrophysics Data System (ADS)

A variety of dark lithic clasts have been reported from CV3 chondrites and are commonly called "dark inclusions" (DIs). The DIs widely range in texture from chondritic with chondrules and Ca-Al-rich inclusions (CAIs) embedded in a matrix (similar to host meteorites), to fine-grained aggregates of Fe-rich olivine free of coarse-grained components [1,2]. The DIs have been interpreted to represent (1) primary aggregates of materials in the solar nebula [3-5] and (2) materials that were affected by thermal metamorphism on their parent bodies [6]. We present the results of petrographic and scanning electron microscope (SEM) studies of two unusual clasts found in the Vigarano CV3 chondrite. The two unusual clasts, which we will call CL1 and CL2, are approximately 1.2 x 1.0 mm^2 (CLl) and 0.8 x 0.6 mm^2 (CL2) and occur within one of the large clasts (2.8 x 1.0 mm^2). CL1 and CL2 have very similar mineralogies and textures; they contain irregular to oval-shaped inclusions consisting mostly of fine grains of Fe-rich olivine embedded in the matrix of the clasts, and are free of distinct chondrules, CAIs, and coarse mineral fragments. Thus, they resemble the fine-grained variety of DIs. Under the optical microscope, most inclusions resemble chondrules or chondrule fragments in shape and size. However, they are brownish-translucent in transmitted light and are clearly distinct from chondrules in the Vigarano host. The inclusions are characteristically flattened in direction, exhibiting apparent foliation. Our SEM observations reveal the following unusual characteristics: (1) the inclusions are not mere random aggregates of olivine grains but have peculiar internal textures, i.e., assemblies of round or oval-shaped outlines, which are suggestive of pseudomorphs after porphyritic or granular olivine chondrules; (2) one of the thick inclusion rims contains a network of vein-like strings of elongated olivine grains, (3) an Fe-Ni metal aggregate in CL1 has an Fe-, Ni-, S-rich halo, suggesting a reaction between its precursor and the surrounding matrix; and (4) olivine in the clasts commonly shows a swirly, fibrous texture similar to that of phyllosilicate. These characteristics are not reconciled with a primary (unprocessed) origin for the clasts but suggest that they were involved in a secondary process such as aqueous alteration. The fine grains of olivine in these clasts were presumably produced by thermal transformation of phyllosilicate. Serpentine is known to start transforming to olivine at >300 degrees C [7]. The inclusions in CL1 and CL2 resemble chondrules: Some of them are surrounded by distinctive rims similar to chondrule rims commonly seen in the carbonaceous chondrites. Therefore, we believe that the precursor material of the clasts would have been related to some types of chondrites, possibly the Vigarano host itself, and that aqueous alteration and thermal metamorphism occurred in the meteorite parent body. We suggest that some of the dark inclusions and clasts previously reported from CV3 chondrites and other types of meteorites may have origins common to these clasts in Vigarano.

Compound ultrarefractory CAI-bearing inclusions from CV3 carbonaceous chondrites  

NASA Astrophysics Data System (ADS)

Abstract-Two compound calcium-aluminum-rich inclusions (CAIs), 3N from the oxidized <span class="hlt">CV</span> chondrite Northwest Africa (NWA) 3118 and 33E from the reduced <span class="hlt">CV</span> chondrite Efremovka, contain ultrarefractory (UR) inclusions. 3N is a forsterite-bearing type B (FoB) CAI that encloses UR inclusion 3N-24 composed of Zr,Sc,Y-rich oxides, Y-rich perovskite, and Zr,Sc-rich Al,Ti-diopside. 33E contains a fluffy type A (FTA) CAI and UR CAI 33E-1, surrounded by Wark-Lovering rim layers of spinel, Al-diopside, and forsterite, and a common forsterite-rich accretionary rim. 33E-1 is composed of Zr,Sc,Y-rich oxides, Y-rich perovskite, Zr,Sc,Y-rich pyroxenes (Al,Ti-diopside, Sc-rich pyroxene), and gehlenite. 3N-24's UR oxides and Zr,Sc-rich Al,Ti-diopsides are 16O-poor (?17O approximately -2‰ to -5‰). Spinel in 3N-24 and spinel and Al-diopside in the FoB CAI are 16O-rich (?17O approximately -23 ± 2‰). 33E-1's UR oxides and Zr,Sc-rich Al,Ti-diopsides are 16O-depleted (?17O approximately -2‰ to -5‰) vs. Al,Ti-diopside of the FTA CAI and spinel (?17O approximately -23 ± 2‰), and Wark-Lovering rim Al,Ti-diopside (?17O approximately -7‰ to -19‰). We infer that the inclusions experienced multistage formation in nebular regions with different oxygen-isotope compositions. 3N-24 and 33E-1's precursors formed by evaporation/condensation above 1600 °C. 3N and 33E's precursors formed by condensation and melting (3N only) at significantly lower temperatures. 3N-24 and 3N's precursors aggregated into a compound object and experienced partial melting and thermal annealing. 33E-1 and 33E avoided melting prior to and after aggregation. They acquired Wark-Lovering and common forsterite-rich accretionary rims, probably by condensation, followed by thermal annealing. We suggest 3N-24 and 33E-1 originated in a 16O-rich gaseous reservoir and subsequently experienced isotope exchange in a 16O-poor gaseous reservoir. Mechanism and timing of oxygen-isotope exchange remain unclear.</p> <div class="credits"> <p class="dwt_author">Ivanova, Marina A.; Krot, Alexander N.; Nagashima, Kazuhide; MacPherson, Glenn J.</p> <p class="dwt_publisher"></p> <p class="publishDate">2012-12-01</p> </div> </div> </div> </div> <div class="floatContainer result odd" lang="en"> <div class="resultNumber element">167</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/24708981"> <span id="translatedtitle">Structure and biological activities of a pectic polysaccharide from Mosla chinensis Maxim. <span class="hlt">cv</span>.

Structural characterization of MP-A40 was investigated by methylation analysis and 1D/2D NMR spectroscopy. From the results, the structure of MP-A40 was revealed as follows: 1,4-linked ?-d-GalpA and 1,4-linked ?-d-GalpA6Me interspersed with rare t-Araf (0.60%), t-Rhap (1.67%) and t-GalpA (10.15%). Esterification assay showed that about 32% of the carboxylic groups in GalA residues existed as methyl ester.

Semillon grown in a Riverina vineyard. To assess the affect of high temperatures on Semillon grapevines, the vines were covered with a protective layer to reduce radiant heating and were compared with vines exposed to ambient conditions. The heat event had major effects on ripening; reducing the rate of ripening by 50% and delaying harvest ripeness and causing a high incidence of berry shrivel and sunburn. Yield was not affected. Photosynthesis was reduced 35% by the heat event while transpiration increased nearly threefold and was accounted for by increased stomatal conductance. The conclusion of this study was that heat events delayed ripening in Semillon berries and caused a significant reduction in berry quality. Strategies to minimize the radiant load during heat events are required and this study has confirmed a protective layer can reduce canopy temperatures and enhance berry quality.</p> <div class="credits"> <p class="dwt_author">Greer, Dennis H.; Weedon, Mark M.</p> <p class="dwt_publisher"></p> <p class="publishDate">2013-01-01</p> </div> </div> </div> </div> <div class="floatContainer result odd" lang="en"> <div class="resultNumber element">169</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://adsabs.harvard.edu/abs/2014ApJ...785...83A"> <span id="translatedtitle">The BANANA Project.

We combine this information with several measurements of changing projected stellar rotation speeds (vsin i sstarf) over the last 30 yr, leading to a model in which the primary star's obliquity is ?65°, and its spin axis precesses around the total angular momentum vector with a period of about 140 yr.

The antioxidant activity of the Pisang Awak methanol extract (PAME) (20-500 microg/ml) was determined using 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging activity, reducing capacity, 2-2'-azinobis-3-ethylbenzothiozoline-6-sulfonic acid (ABTS) radical cation decolourization and hydroxyl radical scavenging capacity (OH*). The EC50 values of DPPH, ABTS and OH* activities of the PAME and butylated hydroxy toluene (BHT) were found to be 65 and 9 microg/ml, 29 and 6 microg/ml, 36 and 42 microg/ml respectively. The reducing capacity increased with increasing concentration (31.5-1000 mg/ml) of the fruit extract and the activity was comparable with the standard BHT. The high performance thin layer chromatography (HPTLC) analysis of the extract revealed the presence of polyphenols. The strong and positive correlations were obtained between total phenol/flavonoid contents (R2 = 0.693-1.0) and free radical scavenging ability was attributed to the polyphenols as the major antioxidants.

The experimental design involved monitoring soil, vine growth, yield components, and fruit composition (soluble solids, flavan-3-ol monomers, proanthocyanidins, and pigmented polymers) on a georeferenced grid pattern to assess patterns in growth and development. Vine vigor parameters (trunk cross-sectional area, average shoot length, and leaf chlorophyll) were used to delineate zones within both blocks to produce research wines to investigate the vine-fruit-wine continuum. There was no significant influence of vine vigor on the amount of proanthocyanidin per seed and only minimal differences in seed proanthocyanidin composition. However, significant increases were found in skin proanthocyanidin (mg/berry), proportion of (-)-epigallocatechin, average molecular mass of proanthocyanidins, and pigmented polymer content in fruit from zones with a reduction in vine vigor. In the wines produced from low-vigor zones, there was a large increase in the proportion of skin tannin extracted into the wine, whereas little change occurred in seed proanthocyanidin extraction. The level of pigmented polymers and proanthocyanidin molecular mass were higher in wines made from low-vigor fruit compared to wines made from high-vigor fruit, whereas the flavan-3-ol monomer concentration was lower.

The wine made with the same grape used for berry skin assays showed a notable presence of quercetin-3-O-glucoside (39.4% of total flavonols), and malvidin and petunidin derivatives (63.9% and 10.8% of total anthocyanins, respectively). The strong antioxidant ROS-scavenging activity, determined by both DPPH and FRAP assays, and the high resveratrol content confer high sensory characteristics resulted to be associated with positive nutraceutical properties of these grapes and wine. The level of cis-resveratrol was lower than trans-resveratrol in both berry skin and wine reaching 44.1mg/kg and 0.3mg/l, respectively.

This innovation has allowed the discovery that, in addition to 13(2) OH chl a and 15(1) OH lactone chl a, which are the first products of POD on chl a, the reaction process sequentially creates another series of oxidised chlorophyll derivatives which have not been previously described. Their origins have been linked to POD activity in the presence of 2,4-DCP. Likewise, a study of the effect of the concentration of the various cosubstrates on the POD reaction rate demonstrated that the correct establishment of the relative concentrations of the same ([H2O2]/[2,4-DCP]/[Chl]=1:3:0.02) is crucial to explaining inhibition effects by substrates and carrying out optimum measurements. Therefore, new essential parameters for the determination of POD activity on a chlorophyll substrate are established.

Fortune mandarin were periodically harvested throughout the ripening period to evaluate changes in carbohydrate content and metabolism in flavedo tissue and to determine the potential role of carbohydrates in the tolerance of citrus fruit to chilling injury (CI). Sucrose showed little change in the flavedo during the season, but fructose and glucose increased, in nearly equal amounts, throughout the fall and winter, reaching a maximum in January. Starch levels were less abundant than soluble carbohydrates and rose continuously until March. Sucrose phosphate synthase (SPS; EC 4.1.14) activity decreased from December throughout ripening. Changes in sucrose synthase (SS; EC 2.4.1.13) and acid and alkaline invertase (Inv; EC 3.2.1.26) activities correlated with changes in the reducing sugars, but acid invertase was less active than the other sucrose-metabolizing enzymes. Carbohydrate changes in the flavedo of Fortune mandarins with fruit maturity appear not to be related to the chilling tolerance of fruits during cold storage.

It was imperative to know the extreme conditions the shuttle tires could tolerate at landing without putting the shuttle and its crew at risk. In addition, the <span class="hlt">CV</span>990 was able to land repeatedly to test the tires. The TAV was built from a kit and modified into a radio controlled, video-equipped machine to drill holes in aircraft test tires that were in imminent danger of exploding because of one or more conditions: high air pressure, high temperatures, and cord wear. An exploding test tire releases energy equivalent to two and one-half sticks of dynamite and can cause severe injuries to anyone within 50 ft. of the explosion, as well as ear injury - possibly permanent hearing loss - to anyone within 100 ft. The degree of danger is also determined by the temperature pressure and cord wear of a test tire. The TAV was developed by David Carrott, a PRC employee under contract to NASA.</p> <div class="credits"> <p class="dwt_author"></p> <p class="dwt_publisher"></p> <p class="publishDate">1995-01-01</p>

Mission) fruit takes place in three distinct periods; two periods (I and III) of rapid growth are separated by a period (II) of slow growth. With respect to exposure to ethylene, the fruit exhibits a two phase response. Ethylene inhibits fruit growth in phase A (period I), the period of cell division, stimulates growth in early phase B (early period II), and stimulates both growth and ripening during the remainder of phase B (late period II and period III). The adverse effect of exogenous ethylene on fruits during phase A is thought to be due to inhibition of cell division. The gradual transition occurring in the response of fruits during phase B was interpreted in terms of carbohydrate level in the fruits.The onset of period III and a respiratory climacteric rise was preceded by or concomitant with a sudden burst of endogenous ethylene synthesis. This, together with the fact that exogenous ethylene applied at the proper stage of fruit growth triggers both ripening and the climacteric rise, leads to the conclusion that ethylene is the causal agent. In other words, the data support the concept that ethylene is a growth hormone that initiates a chain of metabolic and physiological events leading to fig fruit ripening.

BR had its greatest effect on elongation of the apical 3-mm region below the cotyledonary node (75% stimulation) between 6 and 18 h after treatment. Stress/strain (Instron) analysis of this 3-mm region revealed that plastic and elastic components of extension were not significantly different between BR-treated and control seedlings. In pressure-block experiments, the initial rate of relaxation was 2-fold faster in BR-treated plants as compared with controls, whereas after 125 min the total amount of relaxation and the relaxation rate were the same for the two treatments. Osmotic pressure of cell sap expressed from this 3-mm region showed a large decrease (28%) in BR-treated seedlings compared to the controls. The authors conclude that BR stimulates growth in pakchoi by accelerating the biochemical processes that cause wall relaxation, without inducing a large change in wall mechanical properties. 19 refs., 3 figs., 1 tab.</p> <div class="credits"> <p class="dwt_author">Tzannwei Wang; Cosgrove, D.J.; Arteca, R.N.

The irrigation regime had minor effects on the free acidity, peroxide value, and fatty acid composition of VOO. The concentrations of phenols and o-diphenols in VOO were negatively correlated with PLWP. The concentrations of the dialdehydic form of decarboxymethyl elenolic acid linked to (3,4-dihydroxyphenyl)ethanol (3,4-DHPEA-EDA), the isomer of the oleuropein aglycon (3,4-DHPEA-EA), and the dialdehydic form of decarboxymethyl elenolic acid linked to (p-hydroxyphenyl)ethanol (p-HPEA-EDA) were lower in FI than in SI treatments. The concentrations of lignans (+)-1-acetoxipinoresinol and (+)-1-pinoresinol were unaffected by the irrigation regime.

Treatment A received 100% of crop evapotranspiration by a drip irrigation system, a sustained deficit (SDI)treatment B received 60% of crop evapotranspiration, a regulated deficit(RDI) irrigation treatment C received irrigation water before-flowering and just before pit-hardening, and a Dry-farming treatment.

Stomatal conductance was modeled from local meteorological variables, measured sap flow and tree canopy variables. Higher than treatment A and B stomatal conductance and the high tree fruit production recommend treatment C as most suitable for scheduling irrigation of olive orchards in wet years of well distributed late summer rainfall. For drier years of no summer and early autumn rains that minimizes available water to extract by roots outside the wet bulb of drip irrigation and for the scarce readily available irrigation water years, as so often occurs in the region, the sustained deficit irrigation (SDI) regime seems a better option. Nonetheless, for years of limited available water resources that preclude sustained deficit irrigation, careful management of the proposed RDI could also allow for efficient use of irrigation water.</p> <div class="credits"> <p class="dwt_author">Santos, F.

Chasselas). Petioles were highly vulnerable to cavitation, with a 50% loss of hydraulic conductivity at a stem xylem water potential (?x) of –0.95?MPa, and up to 90% loss of conductivity at a ?x of –1.5?MPa. Kpetiole described a daily cycle, decreasing during the day as water stress and evapotranspiration increased, then rising again in the early evening up to the previous morning's Kpetiole levels. In water-stressed vines, PLC increased sharply during the daytime and reached maximum values (70–90%) in the middle of the afternoon. Embolism repair occurred in petioles from the end of the day through the night. Indeed, PLC decreased in darkness in water-stressed vines. PLC variation in irrigated plants showed the same tendency, but with a smaller amplitude. The Chasselas cultivar appears to develop hydraulic segmentation, in which petiole cavitation plays an important role as a ‘hydraulic fuse’, thereby limiting leaf transpiration and the propagation of embolism and preserving the integrity of other organs (shoots and roots) during water stress. In the present study, progressive stomatal closure responded to a decrease in Kpetiole and an increase in cavitation events. Almost total closure of stomata (90%) was measured when PLC in petioles reached >90%.</p> <div class="credits"> <p class="dwt_author">Zufferey, V.; Cochard, H.; Ameglio, T.; Spring, J.-L.; Viret, O.</p> <p class="dwt_publisher"></p> <p class="publishDate">2011-01-01</p> </div> </div> </div> </div> <div class="floatContainer result " lang="en"> <div class="resultNumber element">186</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://adsabs.harvard.edu/abs/2004M%26PS...39.1387W"> <span id="translatedtitle">I-Xe measurements of CAIs and chondrules from the <span class="hlt">CV</span>3 chondrites Mokoia and Vigarano</span></a>  </p> <div class="result-meta"> <p class="source"><a target="_blank" id="logoLink" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p class="result-summary">I-Xe analyses were carried out for chondrules and refractory inclusions from the two <span class="hlt">CV</span>3 carbonaceous chondrites Mokoia and Vigarano (representing the oxidized and reduced subgroups, respectively). Although some degree of disturbance to the I-Xe system is evident in all of the samples, evidence is preserved of aqueous alteration of CAIs in Mokoia 1 Myr later than the I-Xe age of the Shallowater standard and of the alteration of a chondrule (V3) from Vigarano ~0.7 Myr later than Shallowater. Other chondrules in Mokoia and Vigarano experienced disturbance of the I-Xe system millions of years later and, in the case of one Vigarano chondrule (VS1), complete resetting of the I-Xe system after decay of essentially all 129I, corresponding to an age more than 80 Myr after Shallowater. Our interpretation is that accretion and processing to form the Mokoia and Vigarano parent bodies must have continued for at least 4 Myr and 80 Myr, respectively. The late age of a chondrule that shows no evidence for any aqueous alteration or significant thermal processing after its formation leads us to postulate the existence of an energetic chondrule-forming mechanism at a time when nebular processes are not expected to be important.</p> <div class="credits"> <p class="dwt_author">Whitby, J.

General REE fractionations and large (up to 170%) anomalies of Ce, Eu and Yb occur in all chondrule types, particularly for barred olivine and pyroxene-rich chondrules. Positive correlations of REE with the moderately volatile elements, K and Rb, as well as other refractory elements, Ca, Sr and Ba, are independent of textural type and major chemical compositions. Each type of chondrule has large and systematic abundance variations of K and Rb, but shows a constant K/Rb ratio close to that of CIs. From the these results, the following constraints on the chemical characteristics of precursors and chondrule-forming events are suggested: (1) vaporization loss of alkalis accompanied by K/Rb fractionation did not occur during chondrule-formation melting events, (2) elemental abundances were basically established prior to melting events by accretion of alkali-free component(s) and alkali-bearing refractory precursors with fractionated REE, (3) gas/solid (or liquid) processes yielding REE fractionations took place during the formation of refractory precursors.</p> <div class="credits"> <p class="dwt_author">Misawa, K; Nakamura, N.

Murasakizuisho is purple, except the bottom, which is blue. To elucidate the mechanism of the different color development in the same petal, we prepared protoplasts from the purple and blue epidermal regions and measured the flavonoid composition by HPLC, the vacuolar pH by a proton-selective microelectrode, and element contents by the inductively coupled plasma (ICP) method. Chemical analyses revealed that the anthocyanin and flavonol compositions in both purple and blue colored protoplasts were the same; delphinidin 3-O-rutinoside (1) and major three flavonol glycosides, manghaslin (2), rutin (3) and mauritianin (4). The vacuolar pH values of the purple and blue protoplasts were 5.5 and 5.6, respectively, without any significant difference. However, the Fe(3+) content in the blue protoplast was approximately 9.5 mM, which was 25 times higher than that in the purple protoplasts. We could reproduce the purple solution by mixing 1 with two equimolar concentrations of flavonol with lambda(vismax) = 539 nm, which was identical to that of the purple protoplasts. Furthermore, addition of Fe(3+) to the mixture of 1-4 gave the blue solution with lambda(vismax) = 615 nm identical to that of the blue protoplasts. We have established that Fe(3+) is essential for blue color development in the tulip.

The effects were measured after eight days. The energy grass proved to be greatly resistant to the treatments, as was reflected in the slight inhibition of growth, the resistance of the photosynthetic electron transport chain and the chlorophyll composition and the lack of change in the malone-dialdehyde content. Fundamental differences can be identified between the effects of EDTA and citrate. Citrate had only a little effect on the physiological parameters, which may be due to the strongly increasing lead accumulation with increasing concentration of Pb in the nutrient solution. Additionally, citrate ensured a higher biomass yield with higher shoot Pb accumulation compared to EDTA in almost all treatments. Concerning biomass reduction, 10 microM Pb applied together with K2EDTA has the most deleterious effects on energy grass. The effects correlated with the concentration of EDTA.

The partially sequence had 83% homology with a serine protease inhibitor belonging to the Kunitz family, and the protein inhibited chymotrypsin, pepsin, and trypsin.

Mission) fruit takes place in three distinct periods; two periods (I and III) of rapid growth are separated by a period (II) of slow growth. With respect to exposure to ethylene, the fruit exhibits a two phase response. Ethylene inhibits fruit growth in phase A (period I), the period of cell division, stimulates growth in early phase B (early period II), and stimulates both growth and ripening during the remainder of phase B (late period II and period III). The adverse effect of exogenous ethylene on fruits during phase A is thought to be due to inhibition of cell division. The gradual transition occurring in the response of fruits during phase B was interpreted in terms of carbohydrate level in the fruits. The onset of period III and a respiratory climacteric rise was preceded by or concomitant with a sudden burst of endogenous ethylene synthesis. This, together with the fact that exogenous ethylene applied at the proper stage of fruit growth triggers both ripening and the climacteric rise, leads to the conclusion that ethylene is the causal agent. In other words, the data support the concept that ethylene is a growth hormone that initiates a chain of metabolic and physiological events leading to fig fruit ripening.</p> <div class="credits"> <p class="dwt_author">Marei, Nasr; Crane, Julian C.</p> <p class="dwt_publisher"></p> <p class="publishDate">1971-01-01</p> </div> </div> </div> </div> <div class="floatContainer result odd" lang="en"> <div class="resultNumber element">195</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/19919033"> <span id="translatedtitle">Chemical and spectroscopic characteristics of the wood of Vitis vinifera <span class="hlt">cv</span>.

The analyses of the brown-red wood revealed the destruction of hemicelluloses and noncrystalline cellulose as well as modifications in the pectic and ligninic wood fractions. The pectic fraction consisted of carbohydrates associated with polyphenols. The lignin fraction exhibited only a few changes in the aromatic systems and a partial demethylation, and it appeared to be associated with condensed phenolic components probably arising from response polyphenols. The degradation of hemicelluloses and noncrystalline cellulose in brown-red wood, where the pathogens Phaeoacremonium aleophilum and Phaeomoniella chlamydospora prevail with respect to the other fungus Fomitiporia mediterranea, was consistent with reports on the degradative activity of such fungi in vitro carried out on model substrates. The observed alterations could also be attributed to the radical oxidation process caused by the oxidative response of defense itself triggered by infection, as suggested by the accumulation of postinfectional compounds. The analyses of wood tissue with black streaks showed less marked deterioration; here, an increase in pectic and phenolic substances, which probably accumulate in the xylem vessels as a response to the infection, was observed.

Two types of protoplasts were obtained from embryogenic suspension culture: small (20-30 ?m) and larger (30-50 ?m) protoplasts with a dense cytoplasm and large starch grains respectively. The small protoplasts probably originated from embryogenic cell clusters, and also from pseudocambial cells of globules, while larger protoplasts were probably released from oval starchy cells and those of the globule peripheral area. In co-culture with a suitable feeder, consisting of suspensions of diploid banana cells, the protoplasts of triploid banana reformed the cell wall within 24 h and underwent sustained divisions leading to the formation of small clusters of 2-3 cells within 7 days. The latter developed directly into embryos without passing through an apparent callus phase. 10% of such embryos gave rise to plantlets when subcultured in 2.2 ?M 6-benzylaminopurine and 2 ?M 4 amino-3,5,6-trichloropicolinic acid for 1 week, before transfer to MS medium containing 10 ?M 6-benzylaminopurine.

When intact plastids were incubated with apo-peroxidase, a steady-state rate of efflux between 0.12 and 0.45 picomole heme/minute/milligram plastid protein was measured. The efflux rate was not due to plastid breakage and could be enhanced by incubating with the heme precursor, {delta}-aminolevulinic acid.

semileafless mutant, Pisum sativum <span class="hlt">cv</span> Curly. Macroscopic tendril development is subdivided based on thigmotropic capacity. Stage I is the elongation stage and, although the rate of photosynthesis is similar to that of stage II and III tendrils, dark respiration rates are higher in stage I. During stage II, tendrils are thigmotropic and act as a sink. Even though stage II tendrils have CO2 exchange characteristics similar to those of stage III tendrils, which are coiled, our fluorescein, 14C-partitioning, and 11C-translocation experiments suggest that stage I and II tendrils do not export carbon. Only stage III tendrils act as sources of newly fixed carbon. Export from them is blocked by cold, heat girdling of the petiole, or anoxia treatment of the tendrils. A late stage II tendril complex, in which coiling is occurring, may be exporting photoassimilates; however, this phenomenon can be attributed to the fact that the pea leaf is a compound structure and there may be one or more stage III tendrils, no longer thigmotropic, within the tendril complex. Photosynthetic maturity in pea tendrils occurs at stage III and is characterized by the ability of these tendrils to export photoassimilates.

Sulfites are commonly used as effective preservative agents in minimally processing potatoes, but ascorbic acid and citric acid are considered natural sulfite substitutes and more accepted by consumers. The aim of this study was to study the effect of combinations of the preservative agents cited above (sodium metabisulfite 0.1% and 0.5%; citric acid 0.1% and 0.5%; ascorbic acid 0.5%) on the respiration rate of MPP (<span class="hlt">cv</span>. Monalisa) processed at both ambient and refrigerated temperatures. The results have revealed that there is a significant effect of dipping treatment and temperature on respiration rate of MPP. Sodium metabisulfite (SM) reduces respiratory activity up to 0.8 mL/kg/h. The addition of either citric or ascorbic acid enhanced the effect of SM on the reduction of the respiration rate of MPP. The strongest effect (up to 3.3 mL/kg/h) was observed when a combination of all 3 agents at the higher concentrations was employed at a temperature of 18 degrees C.

Because the failure in small-scale facility should be evaluated as a discrete event, we developed the model for estimating both the mean value and the variation of the life-cycle cost (LCC). When the failure loss cost is large, the short replacement cycle is the most cost-effective in a time-based maintenance (TBM), although many cables are replaced. Therefore, the reduction in LCC by taking a condition-based maintenance (CBM) is realized mainly due to the reduction in replaced cables by diagnosis. On the other hand, when the failure loss cost is small, LCC of each cable by taking TBM can be smaller than LCC by CBM in many cables due to the longer replacement cycle without diagnosis. However, the mean value of LCC among 100 cables is still small in CBM, because the total number of failure cables is much smaller in CBM due to the diagnosis. Consequently, LCC can be reduced by CBM, while the reason for the reduction in LCC by CBM, in other words the usability of CBM, depends on the relation between cost for diagnosis, cable replacement and failure loss. The results would be useful in the decision making to take CBM in small scale application.</p> <div class="credits"> <p class="dwt_author">Kato, Takeyoshi; Koyama, Yutaka; Suzuoki, Yasuo</p> <p class="dwt_publisher"></p> <p class="publishDate"></p> </div> </div> </div> </div> <div class="floatContainer result " lang="en"> <div class="resultNumber element">204</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://academic.research.microsoft.com/Publication/37471201"> <span id="translatedtitle">Anthocyanins and flavan-3-ols from grapes and wines of Vitis vinifera <span class="hlt">cv</span>.

TAGs accumulating during embryo development exhibited changes in acyl composition similar to those observed in developing zygotic embryos of the same <span class="hlt">cv</span>, particularly with respect to erucic and eicosenoic acids. However, MD embryos showed a much higher rate of incorporation of 14C-erucoyl moieties into TAGs in vitro than zygotic embryos. Homogenates of early-late cotyledonary stage MD embryos (14-29 days in culture) were assessed for the ability to incorporate 22:1 and 18:1 (oleoyl) moieties into glycerolipids. In the presence of [1-14C]22:1-coenzyme A (CoA) and various acyl acceptors, including glycerol-3-phosphate (G-3-P), radiolabeled erucoyl moieties were rapidly incorporated into the TAG fraction, but virtually excluded from other Kennedy Pathway intermediates as well as complex polar lipids. This pattern of erucoyl incorporation was unchanged during time course experiments or upon incubation of homogenates with chemicals known to inhibit Kennedy Pathway enzymes. In marked contrast, parallel experiments conducted using [1-14C]18:1-CoA and G-3-P indicated that 14C oleoyl moieties were incorporated into lyso-phosphatidic acids, phosphatidic acids, diacylglycerols, and TAGs of the Kennedy Pathway, as well as other complex polar lipids, such as phosphatidylcholines and phosphatidylethanolamines. When supplied with l-[2-3H(N)]G-3-P and [1-14C]22:1-CoA, the radiolabeled TAG pool contained both isotopes, indicating G-3-P to be a true acceptor of erucoyl moieties. Radio-high-performance liquid chromatography, argentation thin-layer chromatography/gas chromatography-mass spectrometry, and stereospecific analyses of radiolabeled TAGs indicated that 22:1 was selectively incorporated into the sn-3 position by a highly active diacylglycerol acyltransferase (DGAT; EC 2.3.1.20), while oleoyl moieties were inserted into the sn-1 and sn-2 positions. In the presence of sn-1,2-dierucin and [1-14C]22:1-CoA, homogenates and microsomal preparations were able to produce radiolabeled trierucin, a TAG not found endogenously in this species. A 105,000g pellet fraction contained 22:1-CoA:DGAT exhibiting the highest specific activity. The rate of 22:1-CoA:DGAT activity in vitro could more than account for the maximal rate of TAG biosynthesis observed in vivo during embryo development.

My8443, a wheat cultivars infecting seriously powdery mildew disease, was used as the female parent and Weiling rye was used as the donor of powdery mildew resistance in the study. A new wheat-rye translocation line,named No.147,was developed from BC2F6 progenies of wheat cultivars My8443 and Weiling rye to transfer the resistance from Weiling rye to common wheat. The powdery mildew resistance of No.147 and its parents were investigated in seedling and adult stages by artificially inoculating the mixture of advanced pathogenic races in room and field and the single pathogenic race in room. Improved Giemsa C-banding technique and genomic in situ hybridization (GISH,Genomic in situ hybridization) were used to identify wheat and rye chromosomes. Acid polyacylamide gel electrophoresis(APAGE) separation of endosperm gliadin and simple sequence repeat(SSR) PCR amplification of 11 SCM-Secale cereale markers also were employed for 1RS confirmation in the study. The results showed that No.147 was a new 1BL/1RS wheat-rye chromosome translocation with high powdery mildew resistance derived from Weiling rye. The reason on the formation of the new wheat-rye chromosome translocation was analyzed. The utilizations of resistance gene resource derived from Chinese Weiling rye and the new 1BL/1RS translocation line in wheat genetics and breeding improvement were discussed in the paper.

It is established that low nitrogen supply stimulates anthocyanin production in berry skin cells of red varieties. The present works aims to gain a better understanding of the molecular mechanisms involved in the response of anthocyanin accumulation to nitrogen supply in berries from field grown-plants. To this end, we developed an integrated approach combining monitoring of plant nitrogen status, metabolite measurements and transcript analysis. Grapevines (<span class="hlt">cv</span>. Cabernet-Sauvignon) were cultivated in a vineyard with three nitrogen fertilization levels (0, 60 and 120kgha(-1) of nitrogen applied on the soil). Anthocyanin profiles were analyzed and compared with gene expression levels. Low nitrogen supply caused a significant increase in anthocyanin levels at two ripening stages (26days post-véraison and maturity). Delphinidin and petunidin derivatives were the most affected compounds. Transcript levels of both structural and regulatory genes involved in anthocyanin synthesis confirmed the stimulation of the phenylpropanoid pathway. Genes encoding phenylalanine ammonia-lyase (PAL), chalcone synthase (CHS), flavonoid-3',5'-hydroxylase (F3'5'H), dihydroflavonol-4-reductase (DFR), leucoanthocyanidin dioxygenase (LDOX) exhibited higher transcript levels in berries from plant cultivated without nitrogen compared to the ones cultivated with 120kgha(-1) nitrogen fertilization. The results indicate that nitrogen controls a coordinated regulation of both positive (MYB transcription factors) and negative (LBD proteins) regulators of the flavonoid pathway in grapevine.

Abosora had the highest activity. alpha-Amylase AI from Abosora peel was purified to homogeneity using anion and cation-exchange, and gel filtration chromatographies. Molecular weight of alpha-amylase AI was found to be 42 kDa. The hydrolysis properties of alpha-amylase AI toward different substrates indicated that corn starch is the best substrate. The alpha-amylase had the highest activity toward glycogen compared with amylopectin and dextrin. Potato starch had low affinity toward alpha-amylase AI but it did not hydrolyze beta-cyclodextrin and dextran. Apparent Km for alpha-amylase AI was 5 mg (0.5%) starch/ml. alpha-Amylase AI showed optimum activity at pH 5.6 and 40 degrees C. The enzyme was thermally stable up to 40 degrees C and inactivated at 70 degrees C. The effect of mono and divalent metal ions were tested for the alpha-amylase AI. Ba2+ was found to have activating effect, where as Li+ had negligible effect on activity. The other metals caused inhibition effect. Activity of the alpha-amylase AI was increased one and half in the presence of 4 mM Ca2+ and was found to be partially inactivated at 10 mM Ca2+. The reduction of starch viscosity indicated that the enzyme is endoamylase. The results suggested that, in addition to citrus peel is a rich source of pectins and flavanoids, alpha-amylase AI from orange peel could be involved in the development and ripening of citrus fruit and may be used for juice processing.

Conférence, which were inoculated with the gram-negative bacterium Erwinia amylovora strain SGB 225/12, were mock-inoculated or were left untreated. The phenylpropanoid-flavonoid pathway was analysed by histological studies, by gene expression using RT-qPCR and by HPLC analyses of the metabolites at different time intervals after infection. Transcription patterns of two key genes anthocyanidin reductase (ANR) and chalcone synthase (CHS) related to the phenylpropanoid-flavonoid pathway showed differences between control, mock-inoculated and E. amylovora-inoculated mature leaves, with the strongest reaction 48 h after inoculation. The impact of E. amylovora was also visualised in histological sections, and confirmed by HPLC, as epicatechin -which is produced via ANR- augmented 72 h after inoculation in infected leaf tissue. Besides the effect of treatments, ontogenesis-related differences were found as well. The increase of certain key genes, the rise in epicatechin and the visualisation in several histological sections in this study suggest a non-negligible impact on the phenylpropanoid-flavonoid pathway in Pyrus communis due to inoculation with E. amylovora. In this study, we propose a potential role of this pathway in defence mechanisms, providing a detailed analysis of the response of this system attributable to inoculation with E. amylovora.

The major fatty acids detected were 2-hydroxynervonic acid (24:1h), 2-hydroxylignoceric acid (24:0h), 2-hydroxyerucic acid (22:1h), and 2-hydroxybehenic acid (22:0h). Long-chain bases of alkaline-hydrolyzed glucocerebrosides consisted primarily of cis-trans isomers of the trihydroxy base 4-hydroxysphingenine (t18:1) and the dihydroxy base sphingadienine (d18:2) with lesser amounts of 4-hydroxysphinganine (t18:0) and isomers of sphingenine (d18:1). Intact, underivatized glucocerebroside molecular species of rye leaf and plasma membrane were separated into more than 30 molecular species using reverse-phase HPLC. The molecular species composition of leaf and plasma membrane were quantitatively and qualitatively similar. The major molecular species was 24:1h-t18:1 which constituted nearly 40 weight percent of leaf and plasma membrane extracts. Several other species including 22:1h-t18:1, 24:1h-t18:1 (isomer), 22:0h-t18:1, 24:1h-d18:2, and 24:0h-t18:1 each comprised 4 to 8% of the total.

The resulting diets were fed for up to 42 days. The toxic nature of FP was expressed by the following dose-related responses: Fluctuating reductions in feed intake upon initiation of diets containing 35% FP and above; occurrence of a potentially fatal, acute central nervous system syndrome at FP levels as low as 35%; and reduced weight gain at FP levels of 52.5% and above.

Alaska seedlings, as described by Saltveit and Dilley (Plant Physiol 1978 61: 447-450), was half-saturated at 3.6% (v/v) O2 and saturated at about 10% O2. Corresponding values for CO2 production during the same period were 1.1% and 10% O2, respectively. Anaerobiosis stopped all ethylene evolution and delayed the characteristic pattern of wound ethylene synthesis. Exposing tissue to 3.5% CO2 in air in a flow-through system reduced wound ethylene synthesis by 30%. Enhancing gas diffusivity by reducing the total pressure to 130 mm Hg almost doubled the rate of wound ethylene synthesis and this effect was negated by exposure to 250 ?l liter?1 propylene. Applied ethylene or propylene stopped wound ethylene synthesis during the period of application, but unlike N2, no lag period was observed upon flushing with air. It is concluded that the characteristic pattern of wound-induced ethylene synthesis resulted from negative feedback control by endogenous ethylene. No wound ethylene was produced for 2 hours after excision at 10 or 38 C. Low temperatures prolonged the lag period, but did not prevent induction of the wound response, since tissue held for 2 hours at 10 C produced wound ethylene immediately when warmed to 30 C. In contrast, temperatures above 36 C prevented induction of wound ethylene synthesis, since tissue cooled to 30 C after 1 hour at 40 C required 2 hours before ethylene production returned to normal levels.

The bulk abundances of Hg are 294 6 15 ng/g in Murchison and 30.0 6 1.5 ng/g in Allende. These values are within the range of previous measurements of bulk Hg abundances by neutron activation analysis (NAA). Prior studies suggested that both meteorites contain isotopically anomalous Hg, with d l 96/202Hg values for the anomalous, thermal-release components from bulk samples ranging from 2260 %o to 1440 9/00 in Murchison and from 2620 9/00 to 1540 9/00 in Allende (Jovanovic and Reed, 1976a; 1976b; Kumar and Goel, 1992). Our multi-collector ICP-MS measurements suggest that the relative abundances of all seven stable Hg isotopes in both meteorites are identical to terrestrial values within 0.2 to 0.5 9/00m. On-line thermal-release experiments were performed by coupling a programmable oven with the singlecollector ICP-MS. Powdered aliquots of each meteorite were linearly heated from room temperature to 900 C over twenty-five minutes under an Ar atmosphere to measure the isotopic composition of Hg released fiom the meteorites as a h c t i o n of temperature. In separate experiments, the release profiles of S and Se were determined simultaneously with Hg to constrain the Hg distribution within the meteorites and to evaluate the possibility of Se interferences in previous NAA studies. The Hg-release patterns differ between Allende and Murchison. The Hg-release profile for Allende contains two distinct peaks, at 225" and 343"C, whereas the profile for Murchison has only one peak, at 344 C. No isotopically anomalous Hg was detected in the thermal-release experiments at a precision level of 5 to 30 9/00, depending on the isotope ratio. In both meteorites the Hg peak at ;340"C correlates with a peak in the S-release profile. This correlation suggests that Hg is associated with S-bearing phases and, thus, that HgS is a major Hg-bearing phase in both meteorites. The Hg peak at 225 C for Allende is similar to release patterns of physically adsorbed Hg on silicate and metal grains.</p> <div class="credits"> <p class="dwt_author">Lauretta, D.

Prior studies suggested that both meteorites contain isotopically anomalous Hg, with ? 196/202Hg values for the anomalous, thermal-release components from bulk samples ranging from -260 ‰ to +440 ‰ in Murchison and from -620 ‰ to +540 ‰ in Allende (Jovanovic and Reed, 1976a; 1976b; Kumar and Goel, 1992). Our multi-collector ICP-MS measurements suggest that the relative abundances of all seven stable Hg isotopes in both meteorites are identical to terrestrial values within 0.2 to 0.5 ‰. On-line thermal-release experiments were performed by coupling a programmable oven with the single-collector ICP-MS. Powdered aliquots of each meteorite were linearly heated from room temperature to 900°C over twenty-five minutes under an Ar atmosphere to measure the isotopic composition of Hg released from the meteorites as a function of temperature. In separate experiments, the release profiles of S and Se were determined simultaneously with Hg to constrain the Hg distribution within the meteorites and to evaluate the possibility of Se interferences in previous NAA studies. The Hg-release patterns differ between Allende and Murchison. The Hg-release profile for Allende contains two distinct peaks, at 225° and 343°C, whereas the profile for Murchison has only one peak, at 344°C. No isotopically anomalous Hg was detected in the thermal-release experiments at a precision level of 5 to 30 ‰, depending on the isotope ratio. In both meteorites the Hg peak at ˜340°C correlates with a peak in the S-release profile. This correlation suggests that Hg is associated with S-bearing phases and, thus, that HgS is a major Hg-bearing phase in both meteorites. The Hg peak at 225°C for Allende is similar to release patterns of physically adsorbed Hg on silicate and metal grains. Prior studies suggested that the isotopic anomalies reported from NAA resulted from interference between 203Hg and 75Se. However, the amount of Se released from both meteorites, relative to Hg, is insufficient to produce all of the observed anomalies.</p> <div class="credits"> <p class="dwt_author">Lauretta, Dante S.; Klaue, Bjoern; Blum, Joel D.; Buseck, Peter R.</p> <p class="dwt_publisher"></p> <p class="publishDate">2001-09-01</p> </div> </div> </div> </div> <div class="floatContainer result " lang="en"> <div class="resultNumber element">236</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/16232424"> <span id="translatedtitle">Phylogenetic position of Mesorhizobium huakuii subsp. rengei, a symbiont of Astragalus sinicus <span class="hlt">cv</span>.

Japan (renge-sou), was studied. The following phylogenetic approaches were used: restriction fragment length polymorphism (RFLP)-polymerase chain reaction (PCR) analysis of a full-length 16S rDNA fragment, 16S rDNA analysis of the first 300-bp sequence, bacteriophage typing, and amplification of the genomic region by random primer. All the data suggest that strains of R. huakuii bv. renge should be classified into subspecies of the new genus Mesorhizobium (Jarvis et al., Inter. J. System. Bacteriol., 47, 895-898, 1997) and renamed M. huakuii subsp. rengei. All the strains fell into a tight cluster which included M. loti and M. huakuii. The strains isolated from root nodules on A. sinicus were divided into three groups as follows: group I, M. huakuii subsp. rengei B3, M. huakuii subsp. rengei My6, M. huakuii subsp. rengei My7, M. huakuii subsp. rengei My3, and M. huakuii subsp. rengei OUT30020; group II, M. huakuii subsp. huakuii CCBAU103(T), M. huakuii subsp. huakuii ACCC13005, M. huakuii subsp. huakuii 7653R, and Mesorhizobium sp. N-1; group III, Mesorhizobium sp. OUT30019. All the strains isolated in Japan except strains N-1 and OUT30019 were classified into group I. Strains in group I were sensitive to bacteriophage H1 which was isolated from rice-paddy soil in Japan. Strains in groups II and III except for M. huakuii subsp. huakuii 7653R were resistant to phage H1. Rhizobium sp. ACMP18, a native symbiont of Astragalus cicer that forms nodules on A. sinicus, showed close similarity to M. huakuii subsp. huakuii CCBAU103(T), and should thus be classified as a Mesorhizobium sp. Taken together, the results of the analyses indicate that M. huakuii subsp. rengei forms a subgroup which is distinct from M. huakuii subsp. huakuii strains isolated in China and that strain B3 is the type strain.

The combination of these techniques on individual CAIs will expand our knowledge of the physical and chemical formation conditions of these enigmatic objects. For our initial report, we will focus on the content(s) of the refractory trace elements Sr, Y, Zr, Nb, Ba, Hf, and Ta. Previous investigations of suites of these elements in bulk Allende refractory inclusions have shown that while there seems to be little Zr/Hf variation from the currently accepted chondritic value of {approx}35, there exist considerable Nb/Ta variations within the same samples. As a whole, this variation is consistent with condensation within in a small temperature range, because Nb oxides are predicted to condense at temperatures very similar (14-40 C) to Tb oxides: suggested that the effect can be explained by efficient condensation of Ta atoms from a gas leaving it enriched in Nb atoms. Here, we investigate the distribution(s) of Zr/Hf and Nb/Ta ratios and their relationships with other refractory trace elements within our suite of 20 CAIs and among the minerals contained in them.</p> <div class="credits"> <p class="dwt_author">Friedrich, J.M.; Jochum, K.P.; Ebel, D.S.

It gives relatively high biomass yield and can grow on marginal lands. However, its yields vary from year to year and from location to location. Thus it is imperative to develop a low input and sustainable switchgrass feedstock production system. One of the most feasible ways to increase biomass yields is to harness benefits of microbial endophytes. Results We demonstrate that one of the most studied plant growth promoting bacterial endophytes, Burkholderia phytofirmans strain PsJN, is able to colonize and significantly promote growth of switchgrass <span class="hlt">cv</span>. Alamo under in vitro, growth chamber, and greenhouse conditions. In several in vitro experiments, the average fresh weight of PsJN-inoculated plants was approximately 50% higher than non-inoculated plants. When one-month-old seedlings were grown in a growth chamber for 30 days, the PsJN-inoculated Alamo plants had significantly higher shoot and root biomass compared to controls. Biomass yield (dry weight) averaged from five experiments was 54.1% higher in the inoculated treatment compared to non-inoculated control. Similar results were obtained in greenhouse experiments with transplants grown in 4-gallon pots for two months. The inoculated plants exhibited more early tillers and persistent growth vigor with 48.6% higher biomass than controls. We also found that PsJN could significantly promote growth of switchgrass <span class="hlt">cv</span>. Alamo under sub-optimal conditions. However, PsJN-mediated growth promotion in switchgrass is genotype specific. Conclusions Our results show B. phytofirmans strain PsJN significantly promotes growth of switchgrass <span class="hlt">cv</span>. Alamo under different conditions, especially in the early growth stages leading to enhanced production of tillers. This phenomenon may benefit switchgrass establishment in the first year. Moreover, PsJN significantly stimulated growth of switchgrass <span class="hlt">cv</span>. Alamo under sub-optimal conditions, indicating that the use of the beneficial bacterial endophytes may boost switchgrass growth on marginal lands and significantly contribute to the development of a low input and sustainable feedstock production system.</p> <div class="credits"> <p class="dwt_author"></p> <p class="dwt_publisher"></p> <p class="publishDate">2012-01-01</p> </div> </div> </div> </div> <div class="floatContainer result odd" lang="en"> <div class="resultNumber element">239</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://adsabs.harvard.edu/abs/2008ApJ...680L.141T"> <span id="translatedtitle">Discovery of a New FUN CAI from a <span class="hlt">CV</span> Carbonaceous Chondrite: Evidence for Multistage Thermal Processing in the Protoplanetary Disk</span></a>  </p> <div class="result-meta"> <p class="source"><a target="_blank" id="logoLink" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p class="result-summary">We report the mineralogy, petrography, as well as oxygen and magnesium isotope data of a newly identified FUN inclusion from the <span class="hlt">CV</span> carbonaceous chondrite NWA 779. Variability in the texture of the mineral phases coupled with oxygen isotope data provides evidence for multistage evolution of this inclusion under distinct thermal regimes: slow crystallization of 16O-rich melt accompanied by evaporation, and subsequent remelting in an 16O-poor reservoir during transient heating events, possibly associated with the formation of <span class="hlt">CV</span> chondrules. The inferred oxygen isotope composition of the precursor material of this inclusion (?17,18O=-48.4+2.5-3.0‰) is consistent with that observed for CAIs and amoeboid olivine aggregates from least metamorphosed carbonaceous chondrites, suggesting that both FUN and normal CAIs formed in an 16O-rich reservoir with oxygen isotope composition similar to that inferred for the Sun. However, in contrast to normal CAIs, most FUN inclusions show no evidence for live 26Al at the time of their formation. Based on these observations, we propose that the protosolar molecular cloud was polluted with stellar-derived 26Al prior to its collapse. Thus, FUN CAIs formed at a time when dust inherited from the molecular cloud-including the carrier of 26Al-was still poorly homogenized in the protoplanetary disk.</p> <div class="credits"> <p class="dwt_author">Thrane, Kristine; Nagashima, Kazuhide; Krot, Alexander N.; Bizzarro, Martin</p> <p class="dwt_publisher"></p> <p class="publishDate">2008-06-01</p> </div> </div> </div> </div> <div class="floatContainer result " lang="en"> <div class="resultNumber element">240</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://ntrs.nasa.gov/search.jsp?R=19890018744&hterms=cbh&qs=Ntx%3Dmode%2Bmatchall%26Ntk%3DAll%26N%3D0%26No%3D20%26Ntt%3D%2522cbh%2522"> <span id="translatedtitle">Interpretation of F106B and <span class="hlt">CV</span>580 in-flight lightning data and form factor determination</span></a>  </p> <div class="result-meta"> <p class="source"><a target="_blank" id="logoLink" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p class="result-summary">Two topics of in-flight aircraft/lightning interaction are addressed.

The <span class="hlt">CV</span>580 data was investigated in a mostly qualitative sense, while the F106B data was subjected to both statistical and quantitative analysis using linear triggered lightning finite difference models. The second main topic is the analysis of field mill data and the calibration of the field mill systems. The calibration of the F106B field mill system was investigated using an improved finite difference model of the aircraft having a spatial resolution of one-quarter meter. The calibration was applied to measured field mill data acquired during the 1985 thunderstorm season. The experimental determination of form factors useful for field mill calibration was also investigated both experimentally and analytically. The experimental effort involved the use of conducting scale models and an electrolytic tank.

Its antioxidant activity on the cyclophosphamide-induced immunosuppressed mice was investigated. The spleen and the thymus indices were investigated, and the biochemical parameters were evaluated in three organs (liver, heart and kidney). MP was able to overcome the cyclophosphamide-induced immunosuppression and can significantly raise the T-AOC, CAT, SOD and GSH-PX level. It also raised the spleen and thymus indices and decreased the MDA level in mice. MP could play an important role during the prevention process of oxidative damage in immunological system.

Grande Naine [AAA]) embryogenic cell suspensions during cryopreservation and regeneration was performed. It was demonstrated that the regeneration process of somatic embryos originating from cryopreserved cell suspensions was different from that of control cell suspensions. Somatic embryos originating from cryopreserved cell suspensions had a unicellular origin. The regeneration process was modified not only by freezing in liquid nitrogen but also by the plasmolyzing effect of the 0.5 M sucrose solution employed during pretreatment. This result explained the high number of embryonic structures formed on M3 medium, compared with the control. Proembryos blocked at the globular stage could pursue their development when they were plated on new culture medium at a lower density after 30 days of culture on M3 medium. The unicellular origin of somatic embryos produced from cryopreserved cell suspensions offers the prospect of using cryopreservation to select non-chimeral transformed plants.

Walp. ssp. unguiculata <span class="hlt">cv</span>.-gr. sesquipedalis] is of particular interest because the genome of this legume has experienced divergent domestication. Initially, cowpea was domesticated from wild cowpea in Africa; in Asia a vegetable form of cowpea, yardlong bean, subsequently evolved from cowpea. Information on the genetics of domestication-related traits would be useful for yardlong bean and cowpea breeding programmes, as well as comparative genome study among members of the genus Vigna. The objectives of this study were to identify quantitative trait loci (QTLs) for domestication-related traits in yardlong bean and compare them with previously reported QTLs in closely related Vigna. Methods Two linkage maps were developed from BC1F1 and F2 populations from the cross between yardlong bean (V. unguiculata ssp. unguiculata <span class="hlt">cv</span>.-gr. sesquipedalis) accession JP81610 and wild cowpea (V. unguiculata ssp. unguiculata var. spontanea) accession TVnu457. Using these linkage maps, QTLs for 24 domestication-related traits were analysed and mapped. QTLs were detected for traits related to seed, pod, stem and leaf. Key Results Most traits were controlled by between one and 11 QTLs. QTLs for domestication-related traits show co-location on several narrow genomic regions on almost all linkage groups (LGs), but especially on LGs 3, 7, 8 and 11. Major QTLs for sizes of seed, pod, stem and leaf were principally located on LG7. Pleiotropy or close linkage of genes for the traits is suggested in these chromosome regions. Conclusions This is the first report of QTLs for domestication-related traits in yardlong bean. The results provide a foundation for marker-assisted selection of domestication-related QTLs in yardlong bean and enhance understanding of domestication in the genus Vigna.</p> <div class="credits"> <p class="dwt_author">Kongjaimun, Alisa; Kaga, Akito; Tomooka, Norihiko; Somta, Prakit; Vaughan, Duncan A.; Srinives, Peerasak</p> <p class="dwt_publisher"></p> <p class="publishDate">2012-01-01</p> </div> </div> </div> </div> <div class="floatContainer result odd" lang="en"> <div class="resultNumber element">253</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=3308158"> <span id="translatedtitle"><span class="hlt">Cv</span>ManGO, a method for leveraging computational predictions to improve literature-based Gene Ontology annotations</span></a>  </p> <div class="result-meta"> <p class="source"><a target="_blank" id="logoLink" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p class="result-summary">The set of annotations at the Saccharomyces Genome Database (SGD) that classifies the cellular function of S. cerevisiae gene products using Gene Ontology (GO) terms has become an important resource for facilitating experimental analysis. In addition to capturing and summarizing experimental results, the structured nature of GO annotations allows for functional comparison across organisms as well as propagation of functional predictions between related gene products. Due to their relevance to many areas of research, ensuring the accuracy and quality of these annotations is a priority at SGD. GO annotations are assigned either manually, by biocurators extracting experimental evidence from the scientific literature, or through automated methods that leverage computational algorithms to predict functional information. Here, we discuss the relationship between literature-based and computationally predicted GO annotations in SGD and extend a strategy whereby comparison of these two types of annotation identifies genes whose annotations need review. Our method, <span class="hlt">Cv</span>ManGO (Computational versus Manual GO annotations), pairs literature-based GO annotations with computational GO predictions and evaluates the relationship of the two terms within GO, looking for instances of discrepancy. We found that this method will identify genes that require annotation updates, taking an important step towards finding ways to prioritize literature review. Additionally, we explored factors that may influence the effectiveness of <span class="hlt">Cv</span>ManGO in identifying relevant gene targets to find in particular those genes that are missing literature-supported annotations, but our survey found that there are no immediately identifiable criteria by which one could enrich for these under-annotated genes. Finally, we discuss possible ways to improve this strategy, and the applicability of this method to other projects that use the GO for curation.

The greenish sepals become photosynthetically competent immediately after pollination and persist until the seeds are set. After the seed set, the entire (green) flower abscises from the plant. Flower development of Helleborus orientalis <span class="hlt">cv</span>. Olympicus growing in the open was divided into six stages (I-VI) from tight bud stage to the senescent stage. The average life span of an individual flower after it is fully open is about 6 days. Membrane permeability of sepal tissues estimated as electrical conductivity of leachates increased during senescence. The content of sugars and soluble proteins in the sepal tissues increased during flower opening and declined thereafter during senescence. The protease activity increased as the flower progressed towards senescence. From the present study, it becomes evident that decline in the sugar status and elevation in specific protease activity leading to degradation of proteins are the important factors regulating development and senescence in H. orientalis flowers. Although the tissue content of soluble proteins registered an overall quantitative decrease but SDS-PAGE of protein extract from sepal tissues suggested a decrease in the expression of high molecular weight proteins and an increase in low molecular weight proteins during flower development and senescence. At this stage it is not known whether the polypeptides that increased during senescence play an important role in the senescence of Helleborus orientalis flowers. The increase in these polypeptides during flower senescence is of particular interest because they may be linked to flower longevity. Understanding the nature of these proteins can provide new insights into the pathways that execute senescence and the post-transcriptional regulation of senescence in this flower system.

While MS medium supplemented with a combination of 2 mg L(-1) BAP + 0.5 mg L(-1) NAA showed the maximum shoot length (14.44 cm). Rooting efficiency of the shoots was highest in the MS basal medium without any PGRs. The plantlets were hardened successfully in the greenhouse with 96% survival rate.

Living at a depth of approximately 2500 meters, these worms experience extreme environmental conditions, including high temperature and pressure as well as high levels of sulfide and heavy metals. A. pompejana is one of the most thermotolerant metazoans, making this animal a subject of great interest for studies of eukaryotic thermoadaptation. Results In order to complement existing EST resources we performed deep sequencing of the A. pompejana transcriptome. We identified several thousand novel protein-coding transcripts, nearly doubling the sequence data for this annelid. We then performed an extensive survey of previously established prokaryotic thermoadaptation measures to search for global signals of thermoadaptation in A. pompejana in comparison with mesophilic eukaryotes. In an orthologous set of 457 proteins, we found that the best indicator of thermoadaptation was the difference in frequency of charged versus polar residues (<span class="hlt">Cv</span>P-bias), which was highest in A. pompejana. <span class="hlt">Cv</span>P-bias robustly distinguished prokaryotic thermophiles from prokaryotic mesophiles, as well as the thermophilic fungus Chaetomium thermophilum from mesophilic eukaryotes. Experimental values for thermophilic proteins supported higher <span class="hlt">Cv</span>P-bias as a measure of thermal stability when compared to their mesophilic orthologs. Proteome-wide mean <span class="hlt">Cv</span>P-bias also correlated with the body temperatures of homeothermic birds and mammals. Conclusions Our work extends the transcriptome resources for A. pompejana and identifies the <span class="hlt">Cv</span>P-bias as a robust and widely applicable measure of eukaryotic thermoadaptation.

Because C. juncea belongs to a genus that is known for the production of toxic dehydropyrrolizidine alkaloids, extracts of the roots, stems, leaves, and seeds of 'Tropic Sun' were analyzed for their presence using HPLC-ESI/MS. Qualitative analysis identified previously unknown alkaloids as major components along with the expected macrocyclic dehydropyrrolizidine alkaloid diesters, junceine and trichodesmine. The dehydropyrrolizidine alkaloids occurred mainly as the N-oxides in the roots, stems, and, to a lesser extent, leaves, but mainly as the free bases in the seeds. Comprehensive spectrometric and spectroscopic analysis enabled elucidation of the unknown alkaloids as diastereoisomers of isohemijunceine, a monoester of retronecine with an unusual necic acid. The dehydropyrrolizidine alkaloid contents of the roots, stems, and leaves of immature plants were estimated to be 0.05, 0.12, and 0.01% w/w, respectively, whereas seeds were estimated to contain 0.15% w/w.

Zhongzhimian KV1) after inoculation with pathogen. cDNAs from the root tissues of Zhongzhimian KV1 inoculated with V. dahliae strain V991 or water mock were used to construct the libraries that contain 4800 clones. Based on the results from dot blot analysis, 147 clones were clearly induced by V. dahliae and selected from the SSH libraries for sequencing. A total of 92 up-regulated and 7 down-regulated non-redundant expressed sequences tags (ESTs) were identified as disease responsive genes and classified into 9 functional groups. Two important clues regarding wilt-resistant G. hirsutum were obtained from this study. One was Bet v 1 family; the other was UbI gene family that may play an important role in the defense reaction against Verticillium wilt. The result from real-time quantitative reverse transcription polymerase chain reaction showed that these genes were activated quickly and transiently after inoculation with V. dahliae.

However, previous studies revealed that both native and recombinant purified P2-G6PDHs show a great instability and a rapid loss of catalytic activity. Therefore it has been difficult to describe accurately the catalytic and physico-chemical properties of these isoforms. The plastidial G6PDH encoding sequence from barley roots (Hordeum vulgare <span class="hlt">cv</span>. Nure), devoid of a long plastidial transit peptide, was expressed as recombinant protein in Escherichia coli, either untagged or with an N-terminal his-tag. After purification from both the soluble fraction and inclusion bodies, we have explored its kinetic parameters, as well as its sensitivity to reduction. The obtained results are consistent with values determined for other P2-G6PDHs previously purified from barley roots and from other land plants. Overall, these data shed light on the catalytic mechanism of plant P2-G6PDH, summarized in a proposed model in which the sequential mechanism is very similar to the mammalian cytosolic G6PDH. This study provides a rational basis to consider the recombinant barley root P2-G6PDH as a good model for further kinetic and structural studies.

Grand Rapids) seedlings cultured in mineral medium. The role of mineral concentrations in this phenomenon was investigated, especially for manganese. When lettuce seedlings were cultured in media that were deficient in calcium (Ca), manganese (Mn), boron (B) or molybdenum (Mo), morphological changes were induced in roots. Deficiency of other nutrients had little effect on root hair formation. Ca or B deficiency inhibited the growth of the main root and the formation of root hairs, regardless of pH. Mn or Mo deficiency increased root hair formation at pH 6 and suppressed main root growth slightly. In contrast, increasing the Mn concentration suppressed low-pH-induced root hair formation. The Mn content of roots grown at pH 4 was only about 15% of that at pH 6. In contrast, the Mo content of roots grown at low pH was about six times that of roots grown at neutral pH. These results suggest that root hair formation induced by low pH is at least partly mediated by decreased Mn uptake in root cells.

Electrophoresis of cold-hardened rye thylakoid proteins revealed the presence of a 35 kilodalton polypeptide and the absence of a 51 kilodalton polypeptide found in nonhardened rye thylakoid proteins. The 35 kilodalton band could be induced by adding ?-mercaptoethanol to nonhardened rye thylakoid proteins, whereas the 51 kilodalton band could be formed by adding cupric phenanthroline to these same proteins. Sulfhydryl group titration showed that cold-hardened rye thylakoid proteins contained more free sulfhydryls than nonhardened rye proteins. Although amino acid analysis of thylakoid proteins revealed quantitative differences in several amino acid residues, the polarity of thylakoid proteins did not change during cold acclimation. No significant changes in sodium dodecyl sulfate-polyacrylamide gels of thylakoid proteins appeared when either nonhardened or cold-hardened plants were frozen in vivo or in vitro. However, thylakoid proteins did aggregate when frozen in the presence of ?-mercaptoethanol. Although thylakoid proteins isolated from cold-hardened rye contained more reduced thiols, a general state of reduction did not act as a cryoprotectant.

The treatments consisted of a mineral supplementation and two other supplements, one based on corn seed and the other based on soybean hulls, and provided at 0.8% of body weight. Forty-eight, 12 month-old crossbred steers with an average initial body weight of 267 kg, were assigned to twelve paddocks (1,125 ha) of guineagrass. The animals that were fed with soybean hulls and corn seed presented a greater average daily gain (0.982 and 0.937) when compared with the mineral supplementation. Soybean hulls can be used as a satisfactory food source, replacing corn as an energy source in the supplementation of beef cattle without compromising animal performance.</p> <div class="credits"> <p class="dwt_author">Santana, M.

Fast growing, high biomass, perennial plants may be used not only in phytoremediation but also in energy production. Szarvasi-1 energy grass (Elymus elongatus subsp. ponticus <span class="hlt">cv</span>. Szarvasi-1), a good candidate for this combined application, was grown in nutrient solution in order to assess its Cd, Cu, Ni, Pb and Zn accumulation and tolerance. Its shoot metal accumulation showed the order Pb < Ni < Cu ? Cd < Zn. In parallel with this, Pb and Ni had no or very little influence on the growth, dry matter content, chlorophyll concentration and transpiration of the plants. Cu and Cd treatment resulted in significant decreases in all these parameters that can be attributed to Fe plaque formation in the roots suggested by markedly increased Fe and Cu accumulation. This came together with decreased shoot and root Mn concentrations in both treatments while shoot Cu and Zn concentrations decreased under Cd and Cu exposure, respectively. Zn treatment had no effect or even slightly stimulated the plants. This may be due to a slight stimulation of Fe translocation and a very efficient detoxification mechanism. Based on the average 300 mg kg?¹ (dry mass) Zn concentration which is 0.03% of the shoot dry mass the variety is suggested to be classified as Zn accumulator.

The ratio between the various pectin fractions of the more acid pH experiment samples remained similar in fruits not showing green staining. In altered fruits, the protopectin fraction was lower, and the calcium pectate or EDTA soluble pectins were higher. Regarding the presence of Ca and Cu in the AIS, it was observed that, whereas Ca levels fell at the most acid pH values, those of Cu increased. The concentration of Ca was higher in the AIS of altered olives than in nonaltered ones. The same trend was seen for the zone with or without green staining of an altered fruit. In the case of Cu, the relationship was the opposite: a decrease in the levels of AIS Cu in fruits and zones of fruits with green staining. This result was correlated with the highest concentration of Cu-chlorophyll complexes found in such samples and suggested that pectins might act as a reservoir of Cu involved in the alteration.

A continuous evolutionary sequence exists between those objects that experienced only slight partial melting or sintering through objects that underwent prolonged melting episodes. In most cases, melting was accompanied by surface evaporative loss of magnesium and silicon. This loss resulted in outer margins that are very different in composition from the cores, so much so that in some cases, the mantles contain mineral assemblages that are petrologically incompatible with those in the cores. The precursor objects for these FoBs had a range of bulk compositions and must therefore have formed under varying conditions if they condensed from a solar composition gas. Five of the six objects show small degrees of mass-dependent oxygen isotopic fractionation in pyroxene, spinel, and olivine, consistent with the inferred melt evaporation, but there are no consistent differences among the three phases. Forsterite, spinel, and pyroxene are 16O-rich with ?17O ˜ -24‰ in all FoBs.

The oils contained palmitic acid (11.9%), oleic acid (79.3%), and linoleic acid (2.95%). The content of palmitic acid and saturated fatty acids decreased during fruit ripening while oleic and linoleic acids increased. The amount of stearic and linolenic acids decreased. The amount of saturated acids, palmitic and stearic, and the polyunsaturated acids linoleic and linolenic was dependent on the time of harvest, whereas the amount of oleic acid varied with the crop year. The differences observed between crop years for both palmitic and linoleic acid may be explained by the differences in the temperature during oil biosynthesis and by the amount of summer rainfall for oleic acid content. A significant relationship was observed between the MUFA/PUFA ratio and the oxidative stability measured by the Rancimat method.

The conversion of ACC to ethylene in the roots was inhibited by low levels of O2, and ACC was apparently transported to the leaves where it was converted to ethylene. ACC synthase activity in the leaves was also stimulated by low O2 treatment to the roots, reaching a peak after 24 hours. ACC synthase levels were enhanced by cobalt chloride and aminooxyacetic acid (AOA), although they inhibited ethylene production. Cobalt chloride enhanced ACC synthase only in combination with low O2 conditions in the roots. Under aeration, AOA stimulated ACC synthase activity in both the roots and leaves.

Then the monoterpenic and norisoprenoidic volatiles released from the same glycosidic extracts under mild acid conditions, mimicking wine aging conditions, have been analyzed using GC-Olfactometry and GC-MS. The most odorous compounds detected were p-cymene, terpinen-4-ol, cis- and trans-vitispiranes, 1,6,6-trimethyl-1,2-dihydronaphtalene (TDN), beta-damascenone and riesling acetal. To assess their potential levels in corresponding wines after ageing, most of these odorants were generated by harsh acid hydrolysis from the precursors extracts and quantitatively determined using SPME and GC-MS/MS. For the development and application of this analysis, the odorants not commercialy available were synthesized.

All fruit treated with 1-MCP had lower respiration and ethylene production compared to untreated controls. Fruit quality changes were delayed following 1-MCP treatment, as was development of superficial scald and peel yellowing. The duration of 1-MCP-induced responses was dependent on 1-MCP treatment concentration. When 1-MCP-treated fruit began to ripen, softening and production of volatile compounds proceeded similar to that of untreated fruit.

The effects of Cd were studied on growth parameters, histology and mineral nutrition. No visible toxic symptoms were observed. Tolerance-index values calculated from growth parameters and nutrients remained relatively high, allowing the development of the plant until maturity and formation of seeds. The roots and bottom stem accumulated the highest quantity of Cd (750 and 360 mg/kg dry matter), values which largely exceeded the threshold defined for hyperaccumulators. On the other hand, basal stem had a high bioconcentration factor (BCF=32) and translocation factor TF' (2.5) but a low TF (0.5), indicating that this basal part would play a major role in phytoremediation (phytostabilization rather than phytorextraction).

In MD flowers, the majority of benzenoid volatile compounds are derived from a core phenylpropanoid pathway intermediate by a coenzyme A (CoA) dependent, ?-oxidative scheme. Metabolic flux analysis, reverse genetics, and biochemical characterizations of key enzymes in this pathway have supported this putative concept. However, the theoretical first enzymatic reaction, which leads to the production of cinnamoyl-CoA, has only been physically demonstrated in a select number of bacteria like Streptomyces maritimus through mutagenesis and recombinant protein production. A transcript has been cloned and characterized from MD flowers that shares high homology with an Arabidopsis thaliana transcript ACYL-ACTIVATING ENZYME11 (AtAAE11) and the S. maritimus ACYL-COA:LIGASE (SmEncH). In MD, the PhAAE transcript accumulates in a very similar manner as bona fide FVBP network genes, i.e. high levels in an open flower petal and ethylene regulated. In planta, PhAAE is localized to the peroxisome. Upon reduction of PhAAE transcript through a stable RNAi approach, transgenic flowers emitted a reduced level of all benzenoid volatile compounds. Together, the data suggest that PhAAE may be responsible for the activation of t-cinnamic acid, which would be required for floral volatile benzenoid production in MD.

The possible effects of different sized AgNPs (20, 30-60, 70-120 and 150nm diameter) on jasmine rice, Oryza sativa L. <span class="hlt">cv</span>. KDML 105, were investigated at different concentrations (0.1, 1, 10, 100 and 1000mg/L) upon seed germination and seedling growth. The results revealed that the level of seed germination and subsequent growth of those seedlings that germinated were both decreased with increasing sizes and concentrations of AgNPs. Based on the analysis of AgNPs accumulation in plant tissues, it implied that the higher uptake was found when the seeds were treated with the smaller AgNPs, 20nm diameter AgNPs, but it was trapped in the roots rather than transported to the leaves. These resulted in the less negative effects on seedling growth, when compared to the seed soaking with the larger AgNPs with 150nm diameter. The negative effects of AgNPs were supported by leaf cell deformation when rice seeds were treated with 150-nm-diameter AgNP at the concentration of 10 or 100mg/L during seed germination. These results further strengthen our understanding of environmental safety information with respect to nanomaterials.

To determine whether SHAM acts on the embryo or the endosperm, we investigated separately effects of SHAM on growth potential of isolated embryos as well as on endosperm strength. Embryo growth potential was quantified by incubating decoated embryos in various concentrations of osmoticum and measuring subsequent radicle elongation. Growth potential of embryos isolated from seeds pretreated with 4 millimolar SHAM was equal to that of untreated controls. Rupture strength of endosperm tissue excised from seeds pretreated with SHAM was 33% less than that of controls in the micropylar region. To determine if the embryo must be in contact with the endosperm of SHAM to weaken the endosperm, some endosperms were incubated with SHAM only after dissection from seeds. Rupture strength of SHAM-treated, isolated endosperms in the micropylar region was 25% less than that of untreated controls. There was no difference in rupture strength in the cotyledonary region of endosperm isolated from seeds treated with SHAM in buffer or buffer alone. SHAM therefore stimulates germination not by enhancing embryo growth potential, but by weakening the micropylar region of the endosperm enclosing the embryo.</p> <div class="credits"> <p class="dwt_author">Brooks, C.

Following removal of the epidermis, a 1 centimeter (inside diameter) glass cylinder was attached to the exposed mesophyll tissue and filled with 5 millimolar CaCl2 solution (1°C). From time-course curves of cumulative K+ diffusion from the tissue, the amount of K+ of extracellular origin was estimated. Apoplastic K+ contents for leaves from plants cultured in nutrient solution containing 2 or 10 millimolar K+ were found to range from 1 to 4.5 micromoles per gram fresh weight, comprising less than 3% of the total K+ content within the lamina tissue. Assuming an apoplastic solution volume of 0.04 to 0.1 milliliters per gram fresh weight and a Donnan cation exchange capacity of 2.63 micromoles per gram fresh weight (experimentally determined), the K+ concentration within apoplastic solution was estimated at 2.4 to 11.8 millimolar. Net movement of Rb+ label from the extracellular compartment within mesophyll tissue into the symplast was demonstrated by pulse-chase experiments. It was concluded that the mesophyll apoplast in pea has a relatively low capacitance as an ion reservoir. Apoplastic K+ content was found to be highly sensitive to changes in xylem solution concentration.

In this study, we applied scanning electron microscopy (SEM) and transmission electron microscopy (TEM) to visualize the ultrastructural changes during somatic embryogenesis of banana (Musa AAA <span class="hlt">cv</span>. 'Yueyoukang 1'). We also used histological and immunohistochemical techniques with 16 monoclonal antibodies to study the spatial distribution and cellular/subcellular localization of different arabinogalactan protein (AGP) components of the cell wall during somatic embryogenesis. Histological study with periodic acid-Schiff staining documented diverse embryogenic stages from embryogenic cells (ECs) to the late embryos. SEM revealed a mesh-like structure on the surface of proembryos which represented an early structural marker of somatic embryogenesis. TEM showed that ECs were rich in juvenile mitochondria, endoplasmic reticulum and Golgi stacks. Cells in proembryos and early globular embryos resembled ECs, but they were more vacuolated, showed more regular nuclei and slightly more developed organelles. Immunocytochemical study revealed that the signal of most AGP epitopes was stronger in starch-rich cells when compared with typical ECs. The main AGP component in the extracellular matrix surface network of banana proembryos was the MAC204 epitope. Later, AGP immunolabelling patterns varied with the developmental stages of the embryos. These results about developmental regulation of AGP epitopes along with developmental changes in the ultrastructure of cells are providing new insights into the somatic embryogenesis of banana.

Until now no transcriptomic data have been reported describing the mechanisms that underlie the agronomic and biochemical effects of thinning. Results We profiled the transcriptome of Vitis vinifera <span class="hlt">cv</span>. Sangiovese berries before and after thinning at veraison using a genome-wide microarray representing all grapevine genes listed in the latest V1 gene prediction. Thinning increased the source/sink ratio from 0.6 to 1.2 m2 leaf area per kg of berries and boosted the sugar and anthocyanin content at harvest. Extensive transcriptome remodeling was observed in thinned vines 2 weeks after thinning and at ripening. This included the enhanced modulation of genes that are normally regulated during berry development and the induction of a large set of genes that are not usually expressed. Conclusion Cluster thinning has a profound effect on several important cellular processes and metabolic pathways including carbohydrate metabolism and the synthesis and transport of secondary products. The integrated agronomic, biochemical and transcriptomic data revealed that the positive impact of cluster thinning on final berry composition reflects a much more complex outcome than simply enhancing the normal ripening process.</p> <div class="credits"> <p class="dwt_author"></p> <p class="dwt_publisher"></p> <p class="publishDate">2011-01-01</p> </div> </div> </div> </div> <div class="floatContainer result odd" lang="en"> <div class="resultNumber element">305</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=1066067"> <span id="translatedtitle">Action of Inhibitors of Ammonia Assimilation on Amino Acid Metabolism in Hordeum vulgare L.

Root ammonia levels increased and glutamine levels decreased, irrespective of whether the plants were grown in 1 millimolar nitrate or 1 millimolar ammonia. Levels of glutamate, aspartate, serine, threonine, and asparagine all increased. There was little alteration in the amino acid and ammonia levels in the shoot, suggesting that MSO is not rapidly transported.

Veery 10). Nitrate consumption, the sum of plant absorption and nitrogen loss, was continuously monitored for 23 d following germination under two CO2 concentrations (360 and 1000 micromol mol-1 CO2) and two root zone NO3- concentrations (100 and 1000 mmol m3 NO3-). The plants were grown at high density (1780 m-2) in a 28 m3 controlled environment chamber using solution culture techniques. Wheat responded to 1000 micromol mol-1 CO2 by increasing carbon allocation to root biomass production. Elevated CO2 also increased root zone NO3- consumption, but most of this increase did not result in higher biomass nitrogen. Rather, nitrogen loss accounted for the greatest part of the difference in NO3- consumption between the elevated and ambient [CO2] treatments. The total amount of NO3(-)-N absorbed by roots or the amount of NO3(-)-N assimilated per unit area did not significantly differ between elevated and ambient [CO2] treatments. Instead, specific leaf organic nitrogen content declined, and NO3- accumulated in canopies growing under 1000 micromol mol-1 CO2. Our results indicated that 1000 micromol mol-1 CO2 diminished NO3- assimilation. If NO3- assimilation were impaired by high [CO2], then this offers an explanation for why organic nitrogen contents are often observed to decline in elevated [CO2] environments.</p> <div class="credits"> <p class="dwt_author">Smart, D.

Using a variety of extraction techniques, followed by detailed chemical analysis, an extensive suite of organic compounds has been identified in carbonaceous chondrites. These data have provided key information on the diversity and isotopic composition of the organic component in chondrites. However, one disadvantage of extraction techniques is that all information regarding the spatial distribution of the organics on a fine scale is lost. This is especially important for the insoluble macromolecular carbon, which constitutes approximately 70% of the carbon in carbonaceous chondrites such as Murchison. The distribution and mineralogical associations may provide important constraints on the possible origins of the carbonaceous material. Our previous studies of the <span class="hlt">CV</span>3 chondrites Allende and Vigarano have demonstrated that energy filtered transmission electron microscopy (EFTEM), combined with high resolution TEM (HRTEM) are powerful tools for the in situ characterization of insoluble organic matter in carbonaceous chondrites.

In the present work, microarrays were made in order (i) to improve our knowledge of grapevine (Vitis vinifera <span class="hlt">cv</span>. Cabernet-Sauvignon) responses to Eutypa lata, the causal agent of Eutypa dieback; and (ii) to identify genes that may prevent symptom development. Qiagen/Operon grapevine microarrays comprising 14?500 probes were used to compare, under three experimental conditions (in vitro, in the greenhouse, and in the vineyard), foliar material of infected symptomatic plants (S+R+), infected asymptomatic plants (S–R+), and healthy plants (S–R–). These plants were characterized by symptom notation after natural (vineyard) or experimental (in vitro and greenhouse) infection, re-isolation of the fungus located in the lignified parts, and the formal identification of E. lata mycelium by PCR. Semi-quantitative real-time PCR experiments were run to confirm the expression of some genes of interest in response to E. lata. Their expression profiles were also studied in response to other grapevine pathogens (Erysiphe necator, Plasmopara viticola, and Botrytis cinerea). (i) Five functional categories of genes, that is those involved in metabolism, defence reactions, interaction with the environment, transport, and transcription, were up-regulated in S+R+ plants compared with S–R– plants. These genes, which cannot prevent infection and symptom development, are not specific since they were also up-regulated after infection by powdery mildew, downy mildew, and black rot. (ii) Most of the genes that may prevent symptom development are associated with the light phase of photosynthesis. This finding is discussed in the context of previous data on the mode of action of eutypin and the polypeptide fraction secreted by Eutypa.</p> <div class="credits"> <p class="dwt_author">Camps, Celine; Kappel, Christian; Lecomte, Pascal; Leon, Celine; Gomes, Eric; Coutos-Thevenot, Pierre; Delrot, Serge</p> <p class="dwt_publisher"></p> <p class="publishDate">2010-01-01</p> </div> </div> </div> </div> <div class="floatContainer result odd" lang="en"> <div class="resultNumber element">329</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=2852660"> <span id="translatedtitle">Agrobacterium-mediated transformation of durum wheat (Triticum turgidum L. var. durum <span class="hlt">cv</span> Stewart) with improved efficiency</span></a>  </p> <div class="result-meta"> <p class="source"><a target="_blank" id="logoLink" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p class="result-summary">An efficient Agrobacterium-mediated durum wheat transformation system has been developed for the production of 121 independent transgenic lines.

Acetosyringone at 400??M was added to both the inoculation and cultivation medium, and picloram at 10?mg l?1 and 2?mg l?1 was used in the cultivation and induction medium, respectively. Compared with 200??M in the inoculation and cultivation media, the increased acetosyringone concentration led to significantly higher GUS (?-glucuronidase) transient expression and T-DNA delivery efficiency. However, no evident effects of acetosyringone concentration on regeneration frequency were observed. The higher acetosyringone concentration led to an improvement in average final transformation efficiency from 4.7% to 6.3%. Furthermore, the concentration of picloram in the co-cultivation medium had significant effects on callus induction and regeneration. Compared with 2?mg l?1 picloram in the co-cultivation medium, increasing the concentration to 10?mg l?1 picloram resulted in improved final transformation frequency from 2.8% to 6.3%, with the highest frequency of 12.3% reached in one particular experiment, although statistical analysis showed that this difference in final transformation efficiency had a low level of significance. Stable integration of foreign genes, their expression, and inheritance were confirmed by Southern blot analyses, GUS assay, and genetic analysis.

We present a petrographic and electron microscopic study of the olivine-rich rims and their host objects (referred to as chondrules/olivine-rich rims). The olivine-rich rims consist mainly of Fe-rich olivine and very minor phyllosilicate (saponite). Their host chondrules contain minor saponite and phlogopite, which resulted from aqueous alteration of anhydrous silicates. Mineralogical and compositional characteristics of the chondrules/olivine-rich rims suggest that they experienced mild thermal metamorphic effects. The rims commonly contain veins of coarse-grained Fe-rich olivine, magnetite, and Fe-(Ni) sulfides. The chondrules show abundant evidence of alteration along their peripheries, and the alteration textures suggest a mechanism for rim formation by replacement of the chondrules. Initially, enstatite and opaque nodules preferentially reacted to form coarse, platy, Fe-rich olivine crystals, which were subsequently divided into finer grains. Forsterite was also replaced by Fe-rich olivine. As the alteration advanced, these Fe-rich olivines were disaggregated, mixed with simultaneously produced saponite, and formed rims. In contrast, the surrounding matrix shows no evidence of such alteration and metamorphism. These observations indicate that the chondrules/olivine-rich rims did not experience these secondary processes in their present setting. The results suggest that the chondrules/olivine-rich rims experienced extensive replacement reactions in an environment in which aqueous fluids existed but only in minor amounts. They have probably also undergone simultaneous and/or subsequent mild thermal metamorphism. We suggest that the chondrules/olivine-rich rims are actually clasts transported from a relatively dry region in the parent body that was different from the region where Mokoia was finally lithified.</p> <div class="credits"> <p class="dwt_author">Tomeoka, Kazushige; Ohnishi, Ichiro</p> <p class="dwt_publisher"></p> <p class="publishDate">2014-07-01</p> </div> </div> </div> </div> <div class="floatContainer result odd" lang="en"> <div class="resultNumber element">331</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=3901204"> <span id="translatedtitle">Root exudation and root development of lettuce (Lactuca sativa L. <span class="hlt">cv</span>.

Although it is well-documented, that physicochemical soil properties can strongly influence root morphology and root exudation, particularly under field conditions, a comparative assessment is complicated by the impact of additional factors, such as climate and cropping history. To overcome these limitations, in this study, field soils originating from an unique experimental plot system with three different soil types, which were stored at the same field site for 10 years and exposed to the same agricultural management practice, were used for an investigation on effects of soil type on root development and root exudation. Lettuce (Lactuca sativa L. <span class="hlt">cv</span>. Tizian) was grown as a model plant under controlled environmental conditions in a minirhizotrone system equipped with root observation windows (rhizoboxes). Root exudates were collected by placing sorption filters onto the root surface followed by subsequent extraction and GC-MS profiling of the trapped compounds. Surprisingly, even in absence of external stress factors with known impact on root exudation, such as pH extremes, water and nutrient limitations/toxicities or soil structure effects (use of sieved soils), root growth characteristics (root length, fine root development) as well as profiles of root exudates were strongly influenced by the soil type used for plant cultivation. The results coincided well with differences in rhizosphere bacterial communities, detected in field-grown lettuce plants cultivated on the same soils (Schreiter et al., this issue). The findings suggest that the observed differences may be the result of plant interactions with the soil-specific microbiomes.</p> <div class="credits"> <p class="dwt_author">Neumann, G.; Bott, S.; Ohler, M.

The purification involved three chromatographic steps: anion exchange chromatography on a Q-Sepharose column, FPLC-anion exchange chromatography on a Mono Q column, and FPLC-gel filtration on a Superdex 75 column. The purified nagaimo lectin presented as a single 35-kDa band in reducing SDS-PAGE while it exhibited a 70-kDa single band in non-reducing SDS-PAGE suggesting its dimeric nature. Nagaimo lectin displayed moderate thermostability, retaining full hemagglutinating activity after heating up to 62°C for 30 minutes. It also manifested stability over a wide pH range from pH 2 to 13. Nagaimo lectin was a galactose-specific lectin, as evidenced by binding with galactose and galactose-containing sugars such as lactose and raffinose. The minimum concentration of galactose, lactose and raffinose required to exert an inhibitory effect on hemagglutinating activity of nagaimo lectin was 20 mM, 5 mM and 40 mM, respectively. Nagaimo lectin inhibited the growth of some cancer cell lines including breast cancer MCF7 cells, hepatoma HepG2 cells and nasopharyngeal carcinoma CNE2 cells, with IC50 values of 3.71 µM, 7.12 µM and 19.79 µM, respectively, after 24 hour treatment with nagaimo lectin. The induction of phosphatidylserine externalization and mitochondrial depolarization indicated that nagaimo lectin evoked apoptosis in MCF7 cells. However, the anti-proliferative activity of nagaimo lectin was not blocked by application of galactose, signifying that the activity was not related to the carbohydrate binding specificity of the lectin.</p> <div class="credits"> <p class="dwt_author">Chan, Yau Sang; Ng, Tzi Bun</p> <p class="dwt_publisher"></p> <p class="publishDate">2013-01-01</p> </div> </div> </div> </div> <div class="floatContainer result odd" lang="en"> <div class="resultNumber element">333</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=2168147"> <span id="translatedtitle">Anaerobic 1-Alkene Metabolism by the Alkane- and Alkene-Degrading Sulfate Reducer Desulfatibacillum aliphaticivorans Strain <span class="hlt">CV</span>2803T?</span></a>  </p> <div class="result-meta"> <p class="source"><a target="_blank" id="logoLink" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p class="result-summary">The alkane- and alkene-degrading, marine sulfate-reducing bacterium Desulfatibacillum aliphaticivorans strain <span class="hlt">CV</span>2803T, known to oxidize n-alkanes anaerobically by fumarate addition at C-2, was investigated for its 1-alkene metabolism. The total cellular fatty acids of this strain were predominantly C-(even number) (C-even) when it was grown on C-even 1-alkenes and predominantly C-(odd number) (C-odd) when it was grown on C-odd 1-alkenes. Detailed analyses of those fatty acids by gas chromatography-mass spectrometry after 6- to 10-week incubations allowed the identification of saturated 2- and 4-ethyl-, 2- and 4-methyl-, and monounsaturated 4-methyl-branched fatty acids with chain lengths that correlated with those of the 1-alkene. The growth of D. aliphaticivorans on (per)deuterated 1-alkenes provided direct evidence of the anaerobic transformation of these alkenes into the corresponding 1-alcohols and into linear as well as 10- and 4-methyl-branched fatty acids. Experiments performed with [13C]bicarbonate indicated that the initial activation of 1-alkene by the addition of inorganic carbon does not occur. These results demonstrate that D. aliphaticivorans metabolizes 1-alkene by the oxidation of the double bond at C-1 and by the subterminal addition of organic carbon at both ends of the molecule [C-2 and C-(?-1)]. The detection of ethyl-branched fatty acids from unlabeled 1-alkenes further suggests that carbon addition also occurs at C-3. Alkylsuccinates were not observed as potential initial intermediates in alkene metabolism. Based on our observations, the first pathways for anaerobic 1-alkene metabolism in an anaerobic bacterium are proposed. Those pathways indicate that diverse initial reactions of 1-alkene activation can occur simultaneously in the same strain of sulfate-reducing bacterium.</p> <div class="credits"> <p class="dwt_author">Grossi, Vincent; Cravo-Laureau, Cristiana; Meou, Alain; Raphel, Danielle; Garzino, Frederic; Hirschler-Rea, Agnes</p> <p class="dwt_publisher"></p> <p class="publishDate">2007-01-01</p> </div> </div> </div> </div> <div class="floatContainer result " lang="en"> <div class="resultNumber element">334</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/23348601"> <span id="translatedtitle">Gelation in protein extracts from cold acclimated and non-acclimated winter rye (Secale cereale L. <span class="hlt">cv</span> Musketeer).</span></a>  </p> <div class="result-meta"> <p class="source"><a target="_blank" id="logoLink" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p class="result-summary">A protein gel is a three-dimensional network consisting of molecular interactions between biopolymers that entrap a significant volume of a continuous liquid phase (water). Molecular interactions in gels occur at junction zones within and between protein molecules through electrostatic forces, hydrogen bonding, hydrophobic associations (van der Waals attractions) and covalent bonding. Gels have the physicochemical properties of both solids and liquids, and are extremely important in the production and stability of a variety of foods, bioproducts and pharmaceuticals. In this study, gelation was induced in phenol extracted protein fractions from non-acclimated (NA) and cold-acclimated (CA) winter rye (Secale cereale L. <span class="hlt">cv</span> Musketeer) leaf tissue after repeated freeze-thaw treatments. Gel formation only occurred at high pH (pH 12.0) and a minimum of 3-4 freeze-thaw cycles were required. The gel was thermally stable and only a specific combination of chemical treatments could disrupt the gel network. SDS-PAGE analysis identified ribulose-1,5-bisphosphate carboxylase oxygenase (Rubisco) as the major protein component in the gel, although Rubisco itself did not appear to be a factor in gelation. Raman spectroscopy suggested changes in protein secondary structure during freeze-thaw cycles. Overall, the NA and CA gels were similar in composition and structure, with the exception that the CA gel appeared to be amyloidic in nature based on thioflavin T (ThT) fluorescence. Protein gelation, particularly in the apoplast, may confer protection against freeze-induced dehydration and potentially have a commercial application to improve frozen food quality.

Wax platelets were extracted from the leaf blades of wheat (Triticum aestivum L., <span class="hlt">c.v</span>. 'Naturastar', Poaceae). Waxes were analysed by gas chromatography (GC) and mass spectrometry (MS). Octacosan-1-ol was found to be the most abundant chemical component of the wax mixture (66 m%) and also the determining compound for the shape of the wax platelets. The electron diffraction pattern showed that both the wax mixture and pure octacosan-1-ol are crystalline. The re-crystallisation of the natural wax mixture and the pure octacosan-1-ol were studied by scanning tunnelling microscopy (STM), atomic force microscopy (AFM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Crystallisation of wheat waxes and pure octacosano-1-ol on the non polar highly ordered pyrolytic graphite (HOPG) led to the formation of platelet structures similar to those found on the plant surface. In contrast, irregular wax morphologies and flat lying plates were formed on glass, silicon, salt crystals (NaCl) and mica surfaces. Movement of wheat wax through isolated Convallaria majalis cuticles led to typical wax platelets of wheat, arranged in the complex patterns typical for C. majalis. STM of pure octacosan-1-ol monolayers on HOPG showed that the arrangement of the molecules strictly followed the hexagonal structure of the substrate crystal. Re-crystallisation of wheat waxes on non-polar crystalline HOPG substrate showed that technical surfaces could be used to generate microstructured, biomimetic surfaces. AFM and SEM studies proved that a template effect of the substrate determined the orientation of the re-grown crystals. These effects of the structure and polarity of the substrate on the morphology of the epicuticular waxes are relevant for understanding interactions between biological as well as technical surfaces and waxes.

There is no way to determine from ground based observation whether the body is a monolithic piece of rock or a rubble-pile, an aggregate of boulders held together by gravity and how much porosity it contains, both in the form of micro-scale or macro-scale porosity. Knowing this structure is a key point for a better understanding of the asteroid accretion and dynamical evolution. It is the main objective of the FANTINA experience proposed Payload for Marco Polo R <span class="hlt">CV</span>3 / ESA mission: FANTINA (Marco Polo's Daughter) for Fathom Asteroids Now: Tomography and Imagery of a NEA is to provide measurement capabilities and science data which are not accessible by remote sensing of the asteroid from the Marco-Polo R spacecraft alone and which complement the analysis of the returned samples. The FANTINA payload is a Lander carrying the ASSERT experiment and a complementary payload to be defined: ASSERT is a bistatic CONSERT/Rosetta-like radar to achieve the tomography both in transmission and in reflexion of the asteroid in order to characterise its composition and its heterogeneity from decimetric to global scale. The lander is a long-lived bus in the 10-kg class derived from MASCOT/Hayabusa 2. This paper reviews the science rationale of FANTINA in the context of the Marco Polo R mission to 1996FG3. The surface package concept will be reviewed including the radar tomography principles.

Glucocerebrosides containing hydroxy fatty acids constituted the major glycolipid class of the plasma membrane, accounting for 16 mole% of the total lipid. Phospholipids, primarily phosphatidylcholine and phosphatidylethanolamine with lesser amounts of phosphatidylglycerol, phosphatidic acid, phosphatidylserine, and phosphatidylinositol, comprised only 32 mole% of the total lipid in NA samples.

Sterol analyses of these lipid classes demonstrated that free ?-sitosterol increased from 21 to 32 mole% (accounting for the increase in free sterols as a class) at the expense of sterol derivatives containing ?-sitosterol. Glucocerebrosides decreased from 16 to 7 mole% of the total lipid following cold acclimation. In addition, the relative proportions of associated hydroxy fatty acids, including 22:0 (h), 24:0 (h), 22:1 (h), and 24:1 (h), were altered. The phospholipid content of the plasma membrane fraction increased to 42 mole% of the total lipid following cold acclimation. Although the relative proportions of the individual phospholipids did not change appreciably after cold acclimation, there were substantial differences in the molecular species. Di-unsaturated molecular species (18:2/18:2, 18:2/18:3, 18:3/18:3) of phosphatidylcholine and phosphatidylethanolamine increased following acclimation.

The initial enzymatic step bridging primary metabolism to secondary metabolism is the condensation of phosphoenolpyruvate (PEP) and erythrose-4-phosphate (E4P) carried out via 3-DEOXY-D-ARABINO-HEPTULOSONATE-7-PHOSPHATE (DAHP) synthase. Here, identified, cloned, localized, and functionally characterized were two DAHP synthases from the model plant species Petunia × hybrida <span class="hlt">cv</span> 'Mitchell Diploid' (MD). Full-length transcript sequences for PhDAHP1 and PhDAHP2 were identified and cloned using cDNA SMART libraries constructed from pooled MD corolla and leaf total RNA. Predicted amino acid sequence of PhDAHP1 and PhDAHP2 proteins were 76% and 80% identical to AtDAHP1 and AtDAHP2 from Arabidopsis, respectively. PhDAHP1 transcript accumulated to relatively highest levels in petal limb and tube tissues, while PhDAHP2 accumulated to highest levels in leaf and stem tissues. Through floral development, PhDAHP1 transcript accumulated to highest levels during open flower stages, and PhDAHP2 transcript remained constitutive throughout. Radiolabeled PhDAHP1 and PhDAHP2 proteins localized to plastids, however, PhDAHP2 localization appeared less efficient. PhDAHP1 RNAi knockdown petunia lines were reduced in total FVBP emission compared to MD, while PhDAHP2 RNAi lines emitted 'wildtype' FVBP levels. These results demonstrate that PhDAHP1 is the principal DAHP synthase protein responsible for the coupling of metabolites from primary metabolism to secondary metabolism, and the ultimate biosynthesis of FVBPs in the MD flower.

Pina and Pinb were detected only on the D-genome of hexaploid wheat and its diploid progenitors while Gsp-1 was on all three homoeologous loci. Hexaploid cultivar Glenlea has a hard phenotype due to a null Pina genotype (D-genome) but the sequence organization is not reported. This study aimed at understanding the evolution of homoeologous Ha loci. Sequencing of three BAC clones from <span class="hlt">cv</span> Glenlea was performed and sequence analyses delimited the Ha loci which spanned 3,925, 5,330 and 31,607 bp in the A-, B- and D-genomes, respectively. A solo LTR of Angela retroelement, downstream to Gsp-A1 and a fragment of Sabrina retroelement, downstream of Gsp-B1, were discovered. We propose that the insertion of these elements into the intergenic regions have driven the deletions of genomic segments harbouring Pina and Pinb genes in the A- and B-genomes of hexaploid wheat. Similarly, fragments of Romani and Vagabond retroelements were identified between truncated Pina and Pinb genes, indicating their role in the deletion of Pina in Glenlea, leading to its hard texture. Structural differences of the Ha locus region of the A-genome between two hexaploid wheat varieties namely Glenlea and Renan (CR626929), suggested the presence of more than one tetraploid ancestor in the origin of hexaploid wheat.

This technique utilizes the Australian Synchrotron X-ray Fluorescence Microscopy (XFM) beam line with its custom designed and built X-ray detector array called Maia. XFM with Maia allows data to be collected using a 2 ?m spot size at very low dwell times (?0.1-0.5 ms), resulting in maps of entire thin sections in ?5 h. Maia is an energy dispersive detector system with a large collection solid-angle, which allows full spectral acquisition and high sensitivity. Hence, there is no need to constrain the elements of interest a priori. We collected whole section maps (?2 cm × 1 cm) from 3 thick sections of Allende and a single map (2 cm × 1.5 cm) from a thick section of Vigarano. Our experimental conditions provide data for elements with 20 ? Z ? 40 (K-shell, Ca through Zr) and the L-emissions of Os, Ir, Pt, Au, and Pb. We illustrate the unique capabilities of this technique by presenting observations across myriad length scales, from the centimeter-scale down to the detection of sub-micrometer particles within these objects. Our initial results show the potential of this technique to help decipher spatial and textural variations in trace element chemistry between CAIs, chondrules, matrix, and other chondritic components. We also illustrate how these datasets can be applied to understanding both nebular and parent-body processes within meteorites.</p> <div class="credits"> <p class="dwt_author">Dyl, Kathryn A.;

Luxor in relation to short and long term periods of cold followed by a brief frost treatment were studied in order to disclose proteins responsible for the cold hardening process in distinct plant tissues. The mentioned changes have been monitored using two dimensional difference gel electrophoresis (2D-DIGE) with subsequent peptide-mapping protein identification. Regarding approximately 600–700 distinct protein spots detected on 2D gels, there has been found at least a two-fold change after exposure to low temperatures in about 10% of proteins in leaves and 13% of proteins in crowns. Protein and nitrogen metabolic processes have been influenced by low temperature to a similar extent in both tissues while catabolism, carbohydrate metabolism and proteins involved in stress response have been more affected in crowns than in leaves. The range of changes in protein abundance was generally higher in leaves and chloroplast proteins were frequently affected which suggests a priority to protect photosynthetic apparatus. Overall, our data proved existence of slightly different response strategies to low temperature stress in crowns and leaves, i.e., tissues with different biological role. Moreover, there have been found several proteins with large increase in accumulation, e.g., 33 kDa oxygen evolving protein of photosystem II in leaves and “enhanced disease susceptibility 1” in crowns; these proteins might have potential to indicate an enhanced level of frost tolerance in barley.</p> <div class="credits"> <p class="dwt_author">Hlavackova, Iva; Vitamvas, Pavel; Santrucek, Jiri; Kosova, Klara; Zelenkova, Sylva; Prasil, Ilja Tom; Ovesna, Jaroslava; Hynek, Radovan; Kodicek, Milan</p> <p class="dwt_publisher"></p> <p class="publishDate">2013-01-01</p> </div> </div> </div> </div> <div class="floatContainer result " lang="en"> <div class="resultNumber element">342</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.editora.ufla.br/revista/29_4/art13.pdf"> <span id="translatedtitle">CONSERVAÇÃO PÓS-COLHEITA DE FIGOS VERDES (Ficus carica L.) <span class="hlt">CV</span>.

The environmental impact of routine, discharges as well as accidental events, notably the Kyshtym accident in 1957 and the Karachay wind dispersion in 1968 have been studied. From measurements and based on model assumptions it has been estimated that the Ob river system outside Mayak, i.e. first of all the Techa and Iset rivers and their floodplains contain 0.1 PBq 90Sr, 0.3 PBq 137Cs and 0.8 TBq 239, 240Pu. The uncertainty of these estimates is a factor of 3-4. The present contamination from the Kyshtym accident outside the Mayak area is calculated to 0.1-0.5 PBq 90Sr and from the Karachay incident the contamination is 0.05-0.1 Bq 137Cs. The environmental contaminations with Pu from these two events are in the order of 1 TBq. The occurrence of 99Tc, 129I and 237Np in highly contaminated Techa river sediments collected outside Mayak is for the first time reported.

Blue Lake) on cycles of 1 minute light-1 minute dark or 5 minutes light-5 minutes dark, providing an integrated 12 hours light-12 hours dark per day for each set of plants, led to production after 21 days of new leaves low or lacking in chloroplast pigments. Subsequently, dry weight increase was sharply cut. Leaf area was affected by the light regimes after the second week of growth. By the fourth week, plants on the 1 minute light-1 minute dark cycle showed about one-half the leaf area of the controls. Shoot growth was favored over root growth to the greatest degree on the 1 minute light-1 minute dark regimes. Chlorophyll a/b ratios were close to 3.0 in all of the intermittent light regimes, but the total amounts of chlorophyll in milligrams per primary leaf were higher from day 9 to day 23 for the 12 hour light-12 hours dark controls than for other plants. Although they produced chlorophyll, the plants receiving 1 or 2 milliseconds per second of light continued to lose weight at the same rate as the dark controls; thus, it is assumed there was no net photosynthesis. Plants receiving flashing light allocated significantly more food reserves from the seed to roots than did dark controls. Total chlorophyll formation was significantly accelerated by 2 milliseconds per second light. With 1 millisecond per second light, it took 5 days longer to achieve the same level of chlorophyll. After the 18th day, there was a steady decline in chlorophyll, b degrading more rapidly than a. It is thought that several light-driven reactions are involved in the observed pigment synthesis, photosynthesis, food allocation, and growth of bean. Some of these reactions may be cyclic and others linear. Collectively, they must reach a harmonic point for normal metabolism and development to occur. Because time courses for each of these reactions are different, the intermittent and flashing light technique offers the possibility of individually studying some of the key light-driven reactions.

This study assessed the impact of the ten-valent pneumococcal nontypable Haemophilus influenzae protein D conjugate vaccine (PHiD-<span class="hlt">CV</span>) on these end points. The primary objective was to demonstrate vaccine efficacy (VE) in a per-protocol analysis against likely bacterial CAP (B-CAP: radiologically confirmed CAP with alveolar consolidation/pleural effusion on chest X-ray, or non-alveolar infiltrates and C-reactive protein ? 40 µg/ml); other protocol-specified outcomes were also assessed. Methods and Findings This phase III double-blind randomized controlled study was conducted between 28 June 2007 and 28 July 2011 in Argentine, Panamanian, and Colombian populations with good access to health care. Approximately 24,000 infants received PHiD-<span class="hlt">CV</span> or hepatitis control vaccine (hepatitis B for primary vaccination, hepatitis A at booster) at 2, 4, 6, and 15–18 mo of age. Interim analysis of the primary end point was planned when 535 first B-CAP episodes, occurring ?2 wk after dose 3, were identified in the per-protocol cohort. After a mean follow-up of 23 mo (PHiD-<span class="hlt">CV</span>, n?=?10,295; control, n?=?10,201), per-protocol VE was 22.0% (95% CI: 7.7, 34.2; one-sided p?=?0.002) against B-CAP (conclusive for primary objective) and 25.7% (95% CI: 8.4%, 39.6%) against World Health Organization–defined consolidated CAP. Intent-to-treat VE was 18.2% (95% CI: 5.5%, 29.1%) against B-CAP and 23.4% (95% CI: 8.8%, 35.7%) against consolidated CAP. End-of-study per-protocol analyses were performed after a mean follow-up of 28–30 mo for CAP and invasive pneumococcal disease (IPD) (PHiD-<span class="hlt">CV</span>, n?=?10,211; control, n?=?10,140) and AOM (n?=?3,010 and 2,979, respectively). Per-protocol VE was 16.1% (95% CI: ?1.1%, 30.4%; one-sided p?=?0.032) against clinically confirmed AOM, 67.1% (95% CI: 17.0%, 86.9%) against vaccine serotype clinically confirmed AOM, 100% (95% CI: 74.3%, 100%) against vaccine serotype IPD, and 65.0% (95% CI: 11.1%, 86.2%) against any IPD. Results were consistent between intent-to-treat and per-protocol analyses. Serious adverse events were reported for 21.5% (95% CI: 20.7%, 22.2%) and 22.6% (95% CI: 21.9%, 23.4%) of PHiD-<span class="hlt">CV</span> and control recipients, respectively. There were 19 deaths (n?=?11,798; 0.16%) in the PHiD-<span class="hlt">CV</span> group and 26 deaths (n?=?11,799; 0.22%) in the control group. A significant study limitation was the lower than expected number of captured AOM cases. Conclusions Efficacy was demonstrated against a broad range of pneumococcal diseases commonly encountered in young children in clinical practice.

The silica grains in the mesostases of the <span class="hlt">CV</span> PRCs are typically replaced by hedenbergitic pyroxenes, whereas anorthitic plagioclase is replaced by feldspathoids (nepheline and minor sodalite). Some of the PRCs contain regions that are texturally and mineralogically similar to type I chondrules and consist of forsterite, low-Ca pyroxene and abundant FeNi-metal nodules. Several PRCs are surrounded by igneous rims or form independent compound objects. Twelve PRCs contain relic calcium-aluminum-rich inclusions (CAIs) composed of anorthite, spinel, high-Ca pyroxene, ?forsterite, and ?Al-rich low-Ca pyroxene. Anorthite of these CAIs is generally more heavily replaced by feldspathoids than anorthitic plagioclase of the host chondrules. This suggests that either the alteration predated formation of the PRCs or that anorthite of the relic CAIs was more susceptible to the alteration than anorthitic plagioclase of the host chondrules. These observations and the presence of igneous rims around PRCs and independent compound PRCs suggest that the <span class="hlt">CV</span> PRCs may have had a complex, multistage formation history compared to a more simple formation history of the CR PRCs. Relatively high abundances of moderately-volatile elements such as Cr, Mn and Si in the PRCs suggests that these chondrules could not have been produced by volatilization of ferromagnesian chondrule precursors or by melting of refractory materials only. We infer instead that PRCs in carbonaceous chondrites formed by melting of the reduced chondrule precursors (magnesian olivine and pyroxene, FeNi-metal) mixed with refractory materials (relic CAIs) composed of anorthite, spinel, high-Ca pyroxene, and forsterite. The mineralogical, chemical and textural similarities of the PRCs in several carbonaceous chondrite groups (<span class="hlt">CV</span>, CO, CH, CR) and common presence of relic CAIs in these chondrules suggest that PRCs may have formed in the region(s) intermediate between the regions where CAIs and ferromagnesian chondrules originated.</p> <div class="credits"> <p class="dwt_author">Krot, A.

Biotechnological techniques, eg., genetic engineering, in vitro mutation breeding, or protoplast fusion, may overcome the difficulties and improve the germplasm. Establishment of a stable embryogenic cell suspension (ECS) is a prerequisite for any of the biotechnological breeding methods. In this study an embryogenic cell suspension was established from immature male flower of Musa acuminata <span class="hlt">cv</span>. Mas (AA), a popular commercial variety of banana in the South-East Asian region. After culture for 5-6 months on callus induction media, which consisted of MS salts, different concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D), 4.1 micromol/L biotin, 5.7 micromol/L indoleacetic acid (IAA), 5.4 micromol/L naphthaleneacetic acid (NAA), other vitamins, 87 mmol/L sucrose, and solidified with 7 g/L agarose, meristematic globules and yellow, friable embryogenic cultures were induced from the explants of 1-15th row young floral hands of immature male flowers. Of the four treatments of 2,4-D, 9 micromol/L was the most effective on the callus induction, it transformed 40.96% and 7.45% of the cultivated male floral hands into callus and embryogenic callus respectively. The explants to produce highest frequency of the embryogenic calli were floral hands of 6 to 12th rows, which generated 5.79% of the embryogenic calli. Suspension cultures were initiated from these embryogenic calli in liquid medium supplemented with 4.5 micromol/L 2, 4-D. After sieving selection of the cultures using a stainless steel metallic strainer with pore sizes of 154 microm at 15 day intervals for 3 months, homogeneous and yellow embryogenic cell suspensions, composed of single cells and small cell aggregates, were established. Based upon the growth quantity and growth rate of ECS, it was determined that the appropriate inoculum was 2.0 mL PCV ECS/30 mL medium in 100 mL flask, and the appropriate subculture cycle was 15 days. Planting of 6 months old ECS on semi-solid medium of somatic embryo induction and development (MSD) resulted in approximately 280 x 10(3) somatic embryos/mL PCV ECS. MSD contained SH macronutrients, micro-nutrients, Fe-EDTA and MS vitamins supplemented with 4.5 micromol/L biotin, 680 micromol/L glutamine, 2 mmol/L proline, 100 mg/L malt extract, 1.1 micromol/L NAA, 0.2 micromol/L zeatin, 0.5 micromol/L kinetin, 0.7 micromol/L N6-(2-isopentenyl) adenine, 29 mmol/L lactose, 130 mmol/L sucrose and solidified with 2g/L gelrite. After 3 months of maturity on MSD, 17.28% of the somatic embryos were germinated on germination media (MG), consisted of MS salt, Morel and Wetmore vitamins, 0.2 micromol/L 6-BA, 1.1 micromol/L IAA, 87 micromol/L sucrose and solidified with 2 g/L gelrite; and 14.16% of the somatic embryos could develop into normal plantlets on rooting media contained the same composition as that of MG but without auxin and cytokinin.

The present study evaluated further the safety, reactogenicity and immunogenicity of a fourth consecutive (booster) dose of PHiD-<span class="hlt">CV</span>. Results: Low incidences of AEs with grade 3 intensity (2.1% of subjects) were observed. There were no reports of large swelling reactions and serious adverse events.

The origin of 2n gametes in citrus is still controversial, although sexual polyploidisation is widely used for triploid seedless cultivar development. In this study, we report the analysis of 2n gametes of mandarin <span class="hlt">cv</span> ‘Fortune' by genotyping 171 triploid hybrids with 35 simple sequence repeat markers. The microsatellite DNA allele counting-peak ratios method for allele-dosage evaluation proved highly efficient in segregating triploid progenies and allowed half-tetrad analysis (HTA) by inferring the 2n gamete allelic configuration. All 2n gametes arose from the female genitor. The observed maternal heterozygosity restitution varied between 10 and 82%, depending on the locus, thus SDR appears to be the mechanism underlying 2n gamete production in mandarin <span class="hlt">cv</span> ‘Fortune'. A new method to locate the centromere, based on the best fit between observed heterozygosity restitution within a linkage group and theoretical functions under either partial or no chiasmata interference hypotheses was successfully applied to linkage group II. The maximum value of heterozygosity restitution and the pattern of restitution along this linkage group would suggest there is partial chiasma interference. The implications of such a restitution mechanism for citrus breeding are discussed.</p> <div class="credits"> <p class="dwt_author">Cuenca, J; Froelicher, Y; Aleza, P; Juarez, J; Navarro, L; Ollitrault, P</p> <p class="dwt_publisher"></p> <p class="publishDate">2011-01-01</p> </div> </div> </div> </div> <div class="floatContainer result odd" lang="en"> <div class="resultNumber element">353</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/12903961"> <span id="translatedtitle">Identification of flavonol and xanthone glycosides from mango (Mangifera indica L. <span class="hlt">Cv</span>.

Changes in flesh colour, ethylene production, membrane permeability, malondialdehyde (MDA), total phenolic contents and the activities of polyphenol oxidase (PPO) and peroxidase (POD) were assayed periodically after harvest and during 44days of storage. The internal morphological characteristics of Nanhui peaches were monitored using magnetic resonance imaging (MRI) at the beginning and end of storage. These data revealed that the EW/MCP treatment is more effective than the EW treatment for decreasing ethylene production and maintaining fruit cell membrane integrity, delaying increases in MDA and total phenolic contents, and lessening changes in PPO and POD activities and the internal morphology of peaches. Each of these effects contributes to suppressing flesh discolouration and maintaining the quality of Nanhui peaches during storage.

Cluster thinning reduced grape yield per vine by around 40% whereas berry thinning only reduced it by around 20%. Cluster thinning grapes had higher soluble solids content than control grapes, and their resultant wines have greater anthocyanin and polysaccharide concentrations than the control wine. Wine obtained from berry thinning grapes had a higher total phenolic index, greater flavonol, proanthocyanidin, and polysaccharide concentrations, and lower titratable acidity than the control wine. Wines obtained from both treatments were sufficiently different from the control wine to be significantly distinguished by a trained panel in a triangular test. Even though both treatments seem to be effective at improving the quality of wine, berry thinning has the advantage because it has less impact on crop yield reduction.

Also, Ballistic Electron Emission Microscopy of Pt/epi-Lu2O3/Si (111) found ˜0.3 - 0.4 eV higher energy barrier than found by Int-PE, suggesting significant transient charge trapping in this sample.

Use was made of functionals with a fixed fraction (?) of Hartree-Fock exchange ranging from ? = 0 to ? = 0.5 as well as functionals with a long range correction (LC) that introduces Hartree-Fock exchange for longer inter-electronic distances. A detailed comparison and analysis is given for each functional between the performance of RSCF-<span class="hlt">CV</span>-DFT and adiabatic time-dependent density functional theory (TDDFT) within the Tamm-Dancoff approximation. It is shown that in this particular case, all functionals afford the same reasonable agreement with experiment for RSCF-<span class="hlt">CV</span>-DFT whereas only the LC-functionals afford a fair agreement with experiment using TDDFT.

Build 4 of the physical map of soybean (Glycine max L. Merr. <span class="hlt">cv</span>. 'Forrest') showed the 1 Gbp haploid genome was composed of 0.7 Gbp diploid, 0.1 Gbp tetraploid and 0.2 Gbp octoploid regions. Therefore, the size of the unique genome was about 0.8 Gbp. The aim here was to create MTP sub-libraries from the soybean <span class="hlt">cv</span>. Forrest physical map builds 2 to 4. Results The first MTP, named MTP2, was 14,208 clones (of mean insert size 140 kbp) picked from the 5,597 contigs of build 2. MTP2 was constructed from three BAC libraries (BamHI (B), HindIII (H) and EcoRI (E) inserts). MTP2 encompassed the contigs of build 3 that derived from build 2 by a series of contig merges. MTP2 encompassed 2 Gbp compared to the soybean haploid genome of 1 Gbp and does not distinguish regions by ploidy. The second and third MTPs, called MTP4BH and MTP4E, were each based on build 4. Each was semi-automatically selected from 2,854 contigs. MTP4BH was 4,608 B and H insert clones of mean size 173 kbp in the large (27.6 kbp) T-DNA vector pCLD04541. MTP4BH was suitable for plant transformation and functional genomics. MTP4E was 4,608 BAC clones with large inserts (mean 175 kbp) in the small (7.5 kbp) pECBAC1 vector. MTP4E was suitable for DNA sequencing. MTP4BH and MTP4E clones each encompassed about 0.8 Gbp, the 0.7 Gbp diploid regions and 0.05 Gbp each from the tetraploid and octoploid regions. MTP2 and MTP4BH were used for BAC-end sequencing, EST integration, micro-satellite integration into the physical map and high information content fingerprinting. MTP4E will be used for genome sequence by pooled genomic clone index. Conclusion Each MTP and associated BES will be useful to deconvolute and ultimately finish the whole genome shotgun sequence of soybean.</p> <div class="credits"> <p class="dwt_author">Shultz, JL; Yesudas, C; Yaegashi, S; Afzal, AJ; Kazi, S; Lightfoot, DA</p> <p class="dwt_publisher"></p> <p class="publishDate">2006-01-01</p> </div> </div> </div> </div> <div class="floatContainer result " lang="en"> <div class="resultNumber element">366</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=1074867"> <span id="translatedtitle">Influence of Seismic Stress on Photosynthetic Productivity, Gas Exchange, and Leaf Diffusive Resistance of Glycine max (L.)

Seismic stress was applied with a gyratory shaker at 240 to 280 revolutions per minute for 5 minutes three times daily at 0930, 1430, and 1930 hours. Fifteen days of treatment decreased stem length 21%, leaf area 17%, and plant dry weight 18% relative to undisturbed plants. Seismic stress also decreased RGR 4%, which was due entirely to decreased net assimilation rate. Transpiration decreased 17% and leaf ?w increased 39% 30 minutes after treatment. A reduction in Pn began within seconds after the onset of treatment and had declined 16% after 20 minutes, at which time gradual recovery began. Assimilation rate recovered fully before the next seismic treatment 5 hours later. Resistance analysis and calculation of leaf internal CO2 levels indicated that the transitory decrease in Pn caused by periodic seismic stress was due to increased stomatal resistance on the abaxial leaf surface.

The source was observed in 1992 to possess traits of a supersoft X-ray source (SSS), with a 0.1-2.4 keV luminosity as large as 2 × 1035 erg s-1, after which time the source's luminosity fell by roughly two orders of magnitude, adopting a hard X-ray spectrum more typical of cataclysmic variables (CVs). Our observations confirm 1E1339's hard <span class="hlt">CV</span>-like spectrum, with photon index ? = 1.3 ± 0.2. We found 1E1339 to be highly variable, with a 0.5-10 keV luminosity ranging from (1.4 ± 0.3) × 1034 erg s-1 to 8.5+4.9 - 4.6 × 1032 erg s-1, with 1E1339's maximum luminosity being perhaps the highest yet recorded for hard X-ray emission from a WD. In 2005 January, 1E1339 displayed substantial low-energy emission below ~0.3 keV. Although current Chandra responses cannot properly model this emission, its bolometric luminosity appears comparable to or greater than that of the hard spectral component. This raises the possibility that the supersoft X-ray emission seen from 1E1339 in 1992 may have shifted to the far-UV.</p> <div class="credits"> <p class="dwt_author">Stacey, W. S.; Heinke, C.

A multidisciplinary approach, combining sensory analysis, consumer testing and detailed chemical analysis was used to better define the relationship between grape maturity, wine composition and sensory quality. The sensory attribute ratings for dark fruit, hotness and viscosity increased in wines produced from riper grapes, while the ratings for the attributes red fruit and fresh green decreased. Consumer testing of the wines revealed that the lowest-alcohol wines (12% v/v) were the least preferred and wines with ethanol concentration between 13% v/v and 15.5% v/v were equally liked by consumers. Partial least squares regression identified that many sensory attributes were strongly associated with the compositional data, providing evidence of wine chemical components which are important to wine sensory properties and consumer preferences, and which change as the grapes used for winemaking ripen.

Marked increases in plant height and in the number of nodes developed per plant together with a modest increase in leaf size were accompanied by dramatic increases (more than 20-fold) in the fresh yields throughout a 50-day growth period. No major changes in the essential oil content per fresh weight and its composition were detected throughout the growth period. In contrast, the compositions of the essential oils obtained from stems, as compared to leaves and leaf-primordia, had marked differences. Developmentally controlled changes in the extractives from individual leaf pairs from the same plant were also noted. In upper young leaves, the oxygenated diterpene manool and the sesquiterpene hydrocarbons alpha-humulene and beta-caryophyllene constituted up to 20%, 8%, and 4% of the total extractives, respectively. In older leaves, the abundance of these components steadily dropped to roughly half their levels in young leaves. Conversely, the proportions of the monoterpenes, particularly the ketones camphor and alpha-thujone, steadily increased with leaf position. Minor changes in the levels of other extractives were also recorded. These studies imply independent regulatory patterns for di-, sesqui-, and monoterpenes in this sage hybrid, and suggest possible agrotechnical means to obtain preferred chemical compositions of its essential oil.

Abnormal granule surface with distinct tumor-like or dented hole features were also observed in raw starch granules. CsCl-washed granules had a smooth surface compared to that of the crude form.

GMKU 3100 deficient in just one of the plant growth promoting traits, siderophore production, was generated by inactivation of a desD-like gene encoding a key enzyme controlling the final step of siderophore biosynthesis. Pot culture experiments revealed that rice and mungbean plants inoculated with the wild type gave the best enhancement of plant growth and significantly increased root and shoot biomass and lengths compared with untreated controls and siderophore-deficient mutant treatments. Application of the wild type in the presence or absence of ferric citrate significantly promoted plant growth of both plants. The siderophore-deficient mutant clearly showed the effect of this important trait involved in plant-microbe interaction in enhancement of growth in rice and mungbean plants supplied with sequestered iron. Our results highlight the value of a substantial understanding of the relationship of the plant growth promoting properties of endophytic actinomycetes to the plants. Endophytic actinomycetes, therefore, can be applied as potentially safe and environmentally friendly biofertilizers in agriculture.

The other cDNAs isolated were placed into one of several categories and encode metabolic enzymes, proteins involved in transcription and translation, components of signal transduction pathways, and homologs of genes whose expression has been shown to be regulated by phytohormones (i.e. auxin, ABA), wounding or other stress responses. RNA gel blot analysis showed that the ADC and ODC transcripts were preferentially expressed in the roots and floral tissues of mature tobacco plants, whereas SAMS transcripts were detected in all tissues examined. The steady-state levels of the ADC and ODC mRNAs increased in the roots of wild-type tobacco plants during the 24 h period after topping, whereas little change was observed in the abundance of the SAMS transcripts in these tissues.

The fully expanded second leaves of wheat plants (Triticum aestivum L. <span class="hlt">cv</span> Avalon) were fumigated with either 200 or 400 nanomoles per mole O{sub 3} for between 4 and 16 hours. This reduced significantly the light-saturated rate of Co{sub 2} uptake and was accompanied by a parallel decrease in stomatal conductance. However, the stomatal limitation only increased significantly during the first 8 hours of exposure to 400 nanomoles per mole O{sub 3}; no significant increase occurred for any of the other treatments. Analysis of the response of CO{sub 2} uptake to the internal Co{sub 2} concentration implied that the predominant factor responsible for the reduction in light-saturated CO{sub 2} uptake was a decrease in the efficiency of carboxylation. At saturating concentrations of Co{sub 2}, photosynthesis was inhibited by no more than 22% after 16 hours, indicating that the capacity for regeneration of ribulose bisphosphate was less susceptible to O{sub 3}. Ozone fumigations also had a less pronounced effect on light-limited photosynthesis. The photochemical efficiency of photosystem II estimated from the ratio of variable to maximum chlorophyll fluorescence and the atrazine-binding capacity of isolated thylakoids demonstrated that photochemical reactions were not responsible for the initial inhibition of CO{sub 2} uptake.</p> <div class="credits"> <p class="dwt_author">Farage, P.K.; Long, S.P.; Baker, N.R.

Early water deficit during the growth period was demonstrated to have beneficial effects on the concentration of anthocyanins and total phenolics in berry skins. A similar pattern was observed for the phenolic content of wines elaborated after vinification of grapes harvested on each plot, in both seasons. Limited water availability seemed to increase glycoconjugates of the main aromatic components of grapes as a quantitative increase in levels of bound volatile compounds of the experimental wines was observed under water deficit in both years. Wines produced from grapes of stressed vineyards were also preferred in tasting trials.

In plant roots, peroxidase (PRX) is thought to be involved in the removal of phenolic pollutants by the cross-linking them to cell wall polysaccharides or proteins at the expense of reduction of hydrogen peroxide (H(2)O(2)). In this study, we found that portulaca roots secreted an acidic PRX isozyme that had relatively high H(2)O(2) affinity. We isolated five PRX genes, and the recombinant PRX proteins produced in cultured tobacco cells were partially characterized. Among these genes, PoPRX2 probably encoded the acidic PRX isozyme. PoPRX2 had an extra N-terminal region which has not been reported for other PRX proteins. We found that PoPRX2 oxidized phenolic pollutants, including bisphenol A, octylphenol, nonylphenol, and 17?-estradiol. In addition, we found that the Cys261 residue of PoPRX2 played an important role in the determination of affinity for H(2)O(2) and stability toward H(2)O(2).

The original design fulfilled the requirements of AE 3001, Aircraft Energy Conservation. AE 3001, offered in the Fall Quarter 1981, and conducted by Professor Allen E. Fuhs, was sponsored in part by the Naval Air Development Center (NADC). NADC desired to obtain the input of several fleet experienced aviators in order to design program code for the HP-41<span class="hlt">CV</span> handheld, programmable calculator that would benefit pilots by providing them with fuel efficiency parameters in flight. Calculators were made available to the participants with the proviso that a completed and operable code for each aircraft be submitted by the end of the academic quarter, September 1981. Upon completion of the E-2C program, attempts were made to use the calculator in flight. One test was conducted informally in an E-2C at RVAW-110, NAS Miramar. Unfortunately, the voltage field induced in the cockpit by the main lobe of the radar passing over the cockpit caused the calculator to cease functioning. The need to devise shielding for the calculator, plus the desire to simplify and improve the existing code lead to this effort.</p> <div class="credits"> <p class="dwt_author">Ferrell, D.R.</p> <p class="dwt_publisher"></p> <p class="publishDate">1982-06-01</p> </div> </div> </div> </div> <div class="floatContainer result " lang="en"> <div class="resultNumber element">378</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/24203137"> <span id="translatedtitle">Callus initiation and plant regeneration from inflorescence primordia of the intergeneric hybrid Agropyron repens (L.)

From the 21st day of culture, one step plant regeneration occurred on the callus without subculture. The new basal medium reported in this work was effective in callus initiation and plant regeneration of the hybrid AGROMUS by (i) the reduction of the total ion strength (2.6 g/l, 22.5 mM) of macroelements compared to MS (4.5 g/l,45.2 mM), (ii) the use of NH4NO3 as the sole N-source, and (iii) the application of KH2PO4 at an 8 times higher concentration (1160 mg/l,8.5 mM) when compared to the Murashige and Skoog medium composition. This medium provided a 2 to 10 fold reduction in the 2,4-dichlorophenoxyacetic acid supplement needed for the callus initiation and one step plant regeneration after a gibberellic acid (2 mg/l, for 5 days) pretreatment of tillers. The regenerated plantlets were subcultured in multi-shoot culture and potted in soil to grow for further analysis.

Moreover, angular resolved XPS (AR-XPS) was used for composition depth profiling of TaCN/HfO2/SiO2/Si stacks. Clear oxidation of the metal electrode through Tasbnd O bonding formation and migration of N in the dielectric with Hfsbnd N are shown. These modifications of chemical bonding give an insight on the electrical results. Low equivalent oxide thicknesses (EOT), as low as 0.89 nm and current leakage improvement by more than 5 decades, are observed for deposition with low plasma power and can be related to HfN content in HfO2 layer. The increase of plasma power used for TaCN deposition results in densification of the layer and promotes the creation of TaC in TaCN material. However H2 plasma has an impact on HfO2 with a reduction and scattering of the measured current leak gain. TaCN/HfO2 interface is also impacted with further creation of TaOx, leading to an increase of EOT when plasma power is increased. Based on these findings, reaction mechanisms with the corresponding Gibbs free energy are proposed.</p> <div class="credits"> <p class="dwt_author">Piallat, Fabien; Beugin, Virginie; Gassilloud, Remy;

The CAI is constructed of two domains, each of which has a core-mantle structure. Reversely zoned melilite crystals were observed in both domains. Melilite crystals in one domain have a homogeneous 16O-poor composition on the carbonaceous chondrite anhydrous mineral (CCAM) line of ?18O = 5-10‰, which suggests that the domain was formed in a 16O-poor oxygen isotope reservoir of the solar nebula. In contrast, melilite crystals in the other domain have continuous variations in oxygen isotopic composition from 16O-rich (?18O = -40‰) to 16O-poor (?18O = 0‰) along the CCAM line. The oxygen isotopic composition tends to be more 16O-rich toward the domain rim, which suggests that the domain was formed in a variable oxygen isotope reservoir of the solar nebula. Each domain of the type A CAI has grown in distinct oxygen isotope reservoir of the solar nebula. After the domain formation, domains were accumulated together in the solar nebula to form a type A CAI.</p> <div class="credits"> <p class="dwt_author">Kawasaki, Noriyuki; Sakamoto, Naoya; Yurimoto, Hisayoshi</p> <p class="dwt_publisher"></p> <p class="publishDate">2012-12-01</p> </div> </div> </div> </div> <div class="floatContainer result " lang="en"> <div class="resultNumber element">382</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/17938113"> <span id="translatedtitle">Polyphenol oxidase and its relationship with oleuropein concentration in fruits and leaves of olive (Olea europaea) <span class="hlt">cv</span>.

Significant increases in PPO specific activity, V(max), K(m )and catalytic efficiency occurred during fruit ripening. Based on SDS-PAGE under partially denaturing conditions and in-gel staining with DL-3,4-dihydroxyphenylalanine, PPO activity was found in one major protein of 55 and 50 kDA in fruits and leaves, respectively. During the last stages of fruit maturation, a second 36 kDa protein was observed in fruits but not in leaves, indicating that this protein could serve as a marker of the final phase of fruit maturation. Under fully denaturing conditions, only one 27.7 kDa immunoreactive band was detected in fruits. Both the amount of PPO activity and the amount of PPO protein increased significantly during fruit maturation. Immunohistochemical studies indicated that PPO is located in the epidermis, parenchyma and companion vascular cells of leaves as well as in the epidermis of fruit. During fruit maturation, oleuropein concentration measured by HPLC significantly decreased in fruits and increased in leaves.

The majority of insert sizes fell into the range of 100+/-20 kb, making them suitable for Agrobacterium-mediated transformation. Only 1% and 0.9% of the clones contain chloroplast and mitochondrial DNA, respectively. This is the first BIBAC library for banana, estimated to represent five times its haploid genome (600 Mbp).

Elevated CO2 concentration significantly increased aboveground biomass, root biomass, and tiller number, whereas double ambient ozone significantly decreased these parameters. These ozone-induced reductions in growth parameters were strongly overridden by 700 ppm CO2. The elevated CO2 level increased C : N ratio of the leaf tissue and leaf starch content but decreased leaf protein levels. Exposure to double ambient ozone did not affect protein content and C : N ratio but dramatically increased leaf starch levels at 700 ppm CO2. Resistance against Drechslera teres (Sacc.)

Virus infection mainly influenced proteins involved in the response to oxidative stress in the berry skin, and proteins involved in cell structure metabolism in the pulp.

In the present study, we isolated an antifungal and antibacterial peptide with no cytotoxicity from tubers of the same potato strain. The peptide (peptide-G2, PG-2) was isolated using salt-extraction, ultrafiltration and reverse-phase high performance liquid chromatography (RP-HPLC). Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) showed the protein to have a molecular mass of 3228.5 Da, while automated Edman degradation showed the N-terminal sequence of PG-2 to be LVKDNPLDISPKQVQALCTDLVIRCMCCC-. PG-2 exhibited antimicrobial activity against Candida albicans, a human pathogenic yeast strain, and Clavibacter michiganensis subsp. michiganensis, a plant late blight strain. PG-2 also showed antibacterial activity against Staphylococcus aureus, but did not lyse human red blood cells and was thermostable. Overall, these results suggest PG-2 may be a good candidate to serve as a natural antimicrobial agent, agricultural pesticide and/or food additive.

Controls, Co2+ and Zn2+-treated plants were grown for 8 days in Hoagland solution. Samples were taken at 2 day intervals. Proline, chlorophyll (a+b) and total protein contents of 17 day old primary leaves were determined by a spectrophotometer. ABA contents in roots and leaves of the seedlings were measured by high-pressure liquid chromatography. The presence of Zn2+ and Co2+ significantly increased the ABA contents in roots and leaves (p < 0.05 or p < 0.01). The increase of the abscisic acid content in the leaves was related to the content of the roots. This was further substantiated by enhanced accumulation of proline in the leaves of seedlings exposed to zinc and cobalt. The contents of chlorophyll (a+b) and total protein decreased with the concentration of both metals (p < 0.05 or p < 0.01). Cobalt proved to be comparatively more toxic than zinc.

The CWM was isolated as the 70% ethanol insoluble residue (de Vries method), as the absolute ethanol insoluble residue filtered sequentially through nylon mesh (Nunan method), as the insoluble residue in sodium deoxycholate-phenol-acetic acid-water (Selvendran method) and as the N-[2-hydroxyethyl]-piperazine-N'-2-ethanesulfonic acid (HEPES) insoluble residue (Vidal method). All extractions were done in triplicate and the efficiency of the extractive procedure established. Carbohydrates, proteins, and phenolic compounds were analysed, as the main constituents of CWM. The morphology of the isolated CWM was visualized by scanning electron microscopy (SEM). The Selvendran method had the highest efficiency, while the Nunan method had the lower one. Regarding the carbohydrates composition, the four different CWM were rich in uronic acids and glucose, together with varying amounts of arabinose, xylose, mannose and galactose. The Selvendran method had the lower value of total carbohydrates and the CWM shows more plasmatic membrane impurities in SEM images. The chemical results of the Vidal and de Vries methods were quite similar, but the Vidal method was more time consuming than the de Vries method. According to the results, the de Vries method was chosen to produce a representative cell-wall material fraction from Monastrell grapes skin.

Malbec exposed (or not) to UV-B both, in in vitro and field experiments. By Head Space-Solid Phase Micro Extraction-Gas Chromatography-Electron Impact Mass Spectrometry (HS-SPME-GC-EIMS) analysis, 10 VOCs were identified at all developmental stages: four monoterpenes, three aldehydes, two alcohols and one ketone. Monoterpenes increased at pre-harvest and in response to UV-B in both, in vitro and field conditions. UV-B also augmented levels of some aldehydes, alcohols and ketones. These results along with others from the literature suggest that UV-B induce grape berries to produce VOCs (mainly monoterpenes) that protect the tissues from UV-B itself and other abiotic and biotic stresses, and could affect the wine flavor. Higher emission of monoterpenes was observed in the field experiments as compared in vitro, suggesting the UV-B/PAR ratio is not a signal in itself.

Native arcelin-1 is a dimeric glycoprotein of 60 kDa, built from the non-covalent association of two identical monomers. This dimer resists dissociation by chaotropic agents and is highly resistant to proteolytic enzymes. Each subunit contains 10% (w/w) neutral sugars which belong to the high-mannose and complex-type glycans attached to three glycosylation sites. No interaction of the protein with simple sugars could be detected, but arcelin-1 displays an intrinsic specificity in binding complex glycans. Arcelin-1 therefore differs from the closely related phytohaemagglutinin lectins and alpha-amylase inhibitor in several respects: oligomerization states, sugar-binding affinities and the type and number of glycan chains.

Exogenous ethylene treatments did not make Sparkle mimic R82, and inhibitors of ethylene biosynthesis or action did not normalize the phenotype of R82. The data suggest that the primary effect of sym-17 is not the enhanced ethylene production.

Tobacco (Nicotiana tabacum L. <span class="hlt">cv</span>. Petit Havana SR1) hairy roots, which do not produce geraniol naturally, were engineered to express a plastid-targeted geraniol synthase gene originally isolated from Valeriana officinalis L. (VoGES). A SPME-GC-MS screening tool was developed for the rapid evaluation of production clones. The GC-MS analysis revealed that the free geraniol content in 20 hairy root clones expressing VoGES was an average of 13.7?g/g dry weight (DW) and a maximum of 31.3?g/g DW. More detailed metabolic analysis revealed that geraniol derivatives were present in six major glycoside forms, namely the hexose and/or pentose conjugates of geraniol and hydroxygeraniol, resulting in total geraniol levels of up to 204.3?g/g DW following deglycosylation. A benchtop-scale process was developed in a 20-L wave-mixed bioreactor eventually yielding hundreds of grams of biomass and milligram quantities of geraniol per cultivation bag.

These three bacteria are saprophytes that occasionally become aggressive opportunistic pathogens virulently attacking animals (the first two) and plants (the third). The recent availability of their genome sequences enabled identification in the C. violaceum genome of an ORF (locus no. 1744) that is similar to those of P. aeruginosa and R. solanacearum lectins, PA-IIL and RS-IIL, respectively. A recombinant protein, <span class="hlt">CV</span>-IIL, encoded by that ORF exhibited fucose>mannose-specific lectin activity resembling PA-IIL. This paper describes production and properties of the native <span class="hlt">CV</span>-IIL, which, like PA-IIL and RS-IIL, is probably also a quorum-sensing-driven secondary metabolite, appearing concomitantly with violacein. Its formation is repressed in the <span class="hlt">CV</span>026 mutant of C. violaceum, which lacks endogenous N-acylhomoserine lactone. The upstream extragenic sequence of its ORF contains a 20 bp sequence (5'-101-120) with partial similarities to the luxI-box and the related P. aeruginosa and R. solanacearum promoter boxes of quorum-sensing-controlled genes. The lectin level is augmented by addition of trehalose to the medium. The subunit size of <span class="hlt">CV</span>-IIL (around 11.86 kDa) is similar to those of PA-IIL (11.73 kDa) and RS-IIL (11.60 kDa). Like PA-IIL, in the tetrameric form <span class="hlt">CV</span>-IIL preferentially agglutinates alpha1-2 fucosylated H-positive human erythrocytes (regardless of their A, B or O type), as opposed to the O(h) Bombay type, but differs from it in having no interaction with rabbit erythrocytes and in displaying stronger affinity to l-galactose than to l-fucose. The greater similarity of <span class="hlt">CV</span>-IIL to PA-IIL than to RS-IIL might be related to the selective adaptation of both C. violaceum and P. aeruginosa to animal tissues versus the preferential homing of R. solanacearum to plants.

M82 (Solanum lycopersicum) × LA0716 (S. pennellii) have been proven to be exceptionally useful for genetic analysis and gene cloning. The introgressions were originally defined by RFLP markers at their development. The objectives of this study are to develop polymorphic SSR markers, and to re-define the DNA introgression from LA0716 in the ILs. Tomato sequence data was scanned by software to generate SSR markers. In total, 829 SSRs, which could be robustly amplified by PCR, were developed. Among them, 658 SSRs were dinucleotide repeats, 162 were trinucleotide repeats, and nine were tetranucleotide repeats. The 829 SSRs together with 96 published RFLPs were integrated into the physical linkage map of S. lycopersicum. Introgressions of DNA fragments from LA0716 were re-defined among the 75 ILs using the newly developed SSRs. A specific introgression of DNA fragment from LA0716 was identified in 72 ILs as described previously by RFLP, whereas the specific DNA introgression described previously were not detected in the ILs LA4035, LA4059 and LA4091. The physical location of each investigated DNA introgression was finely determined by SSR mapping. Among the 72 ILs, eight ILs showed a shorter and three ILs (IL3-2, IL12-3 and IL12-3-1) revealed a longer DNA introgression than that framed by RFLPs. Furthermore, 54 previously undefined segments were found in 21 ILs, ranging from 1 to 11 DNA introgressions per IL. Generally, the newly developed SSRs provide additional markers for genetic studies of tomatoes, and the fine definition of DNA introgressions from LA0716 would facilitate the use of the ILs for genetic analysis and gene cloning.</p> <div class="credits"> <p class="dwt_author">Long, Wenbo; Li, Ye; Zhou, Wenjuan; Ling, Hong-Qing; Zheng, Shusong</p> <p class="dwt_publisher"></p> <p class="publishDate">2013-01-01</p> </div> </div> </div> </div> <div class="floatContainer result " lang="en"> <div class="resultNumber element">404</div> <div class="resultBody element"> <p class="result-title"><a target="resultTitleLink" href="http://science.gov/scigov/link.html?type=RESULT&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/24443499"> <span id="translatedtitle">A role for PacMYBA in ABA-regulated anthocyanin biosynthesis in red-colored sweet cherry <span class="hlt">cv</span>.

The present study describes the first functional characterization of an R2R3-MYB transcription factor, PacMYBA, from red-colored sweet cherry <span class="hlt">cv</span>. Hong Deng (Prunus avium L.). Transient promoter assays demonstrated that PacMYBA physically interacted with several anthocyanin-related basic helix-loop-helix (bHLH) transcription factors to activate the promoters of PacDFR, PacANS and PacUFGT, which are thought to be involved in anthocyanin biosynthesis. Furthermore, the immature seeds of transgenic Arabidopsis plants overexpressing PacMYBA exhibited ectopic pigmentation. Silencing of PacMYBA, using a Tobacco rattle virus (TRV)-induced gene silencing technique, resulted in sweet cherry fruit that lacked red pigment. ABA treatment significantly induced anthocyanin accumulation, while treatment with the ABA biosynthesis inhibitor nordihydroguaiaretic acid (NDGA) blocked anthocyanin production. PacMYBA expression peaked after 2 h of pre-incubation in ABA and was 15.2-fold higher than that of sweet cherries treated with NDGA. The colorless phenotype was also observed in the fruits silenced in PacNCED1, which encodes a key enzyme in the ABA biosynthesis pathway. The endogenous ABA content as well as the transcript levels of six structural genes and PacMYBA in PacNCED1-RNAi (RNA interference) fruit were significantly lower than in the TRV vector control fruit. These results suggest that PacMYBA plays an important role in ABA-regulated anthocyanin biosynthesis and ABA is a signal molecule that promotes red-colored sweet cherry fruit accumulating anthocyanin.

Olives of the <span class="hlt">cv</span>. Nostrana di Brisighella grown in the north-central Italian region of Emilia-Romagna were picked at four different stages of ripeness and immediately processed in an experimental mill. The polar extracts of oil samples were submitted to spectrophotometric analysis of total phenols and o-diphenols and to liquid chromatographic determination of their quali-quantitative profile (HPLC-DAD/MSD). To attain a complete description of oil samples, fatty acid composition, ultraviolet indices (K(232), K(270), and deltaK), free acidity degree, and peroxide value were also determined according to the European Union methods stated in Regulation 2568/91 (1, Off. J. Eur. Communities 1991, L248, 1-82). Sensory quantitative descriptive analysis (QDA) and triangular tests were performed to establish the influence of olive ripening degree on the resulting oil's organoleptic properties. The evolution of the analytical parameters studied shows that the ripeness stage of Nostrana di Brisighella olives that yields the best oil corresponds to a Jaén index value between 2.5 and 3.5. Oils produced from olives harvested within this time frame present a superior sensory profile accompanied by the highest possible chemical and nutritional properties.

Various PEF treatments using electric field strength between 0.2 and 1.2kV/cm and pulsed electrical energy between 1 and 520kJ/kg were conducted. The enzyme kinetics and the kinetics of AAO thermal inactivation (55-70°C) were described using Michaelis-Menten model and first order reaction model, respectively. Overall, the estimated Vmax and KM values were situated in the same order of magnitude as the untreated carrot purée after being exposed to pulsed electrical energy between 1 and 400kJ/kg, but slightly changed at pulsed electrical energy above 500kJ/kg. However, AAO presented different thermostability depending on the electric field strength applied. After PEF treatment at the electric field strength between 0.2 and 0.5kV/cm, AAO became thermolabile (i.e. increase in inactivation rate (k value) at reference temperature) but the temperature dependence of k value (Ea value) for AAO inactivation in carrot purée decreased, indicating that the changes in k values were less temperature dependent. It is obvious that PEF treatment affects the temperature stability of endogenous AAO. The changes in enzyme kinetics and thermostability of AAO in carrot purée could be related to the resulting carrot purée composition, alteration in intracellular environment and the effective concentration of AAO released after being subjected to PEF treatment.

In contrast to other organisms, plants have a great number of Trx types, consisting of six well-defined groups: f, m, x, and y in chloroplasts, o in mitochondria, and h mainly in cytosol. A full-length cDNA, designated VvCxxS2, encoding Trx h polypeptide was isolated and cloned from grape (Vitis vinifera L. <span class="hlt">cv</span>. Askari) berries organ by reverse transcription polymerase chain reaction (RT-PCR). The cDNA was 381 bp nucleotides in length with a deduced amino acid of 126 residues, possessing a WCIPS active site, which belongs to the subgroup III of h-type Trxs based on phylogenetic analysis. The calculated molecular mass and the predicted isoelectric point of the deduced polypeptide are 14.25 kDa and 4.68, respectively. Nucleotide sequence analysis of genomic DNA fragment of VvCxxS2 gene revealed that this gene possesses two introns at positions identical to the previously sequenced Trx h genes. A modeling analysis indicated that VvCxxS2 shares a common structure with other Trxs, and is preferably reduced by Grx rather than NADPH-dependent thioredoxin reductase (NTR). The deduced protein sequence showed a high similarity to Trx h from other plants, in particular from castor bean (Ricinus communis), Betula pendula and sweet orange (Citrus sinensis). Semiquantitative RT-PCR experiments indicated that the transcripts of VvCxxS2 gene are present in all plant organs and different developmental stages. In addition, the higher expression of the VvCxxS2 gene was observed in berry organ as compared to the other organs.

Cold, for example, affects the elongation of the stalk, thereby influencing the quality of the cut flower. How the elongation of the stalk is promoted by cold and which physiological and biochemical mechanisms are involved have remained obscure. As invertase has been shown to be involved in the cold-induced elongation of the flower stalks of tulips (Lambrechts et al., 1994, Plant Physiol 104: 515-520), we further characterized this enzyme by cloning the cDNA and analysing its expression in various tissues of the tulip (Tulipa gesneriana L. <span class="hlt">cv</span>. Apeldoorn) stalk. In addition, the role of sucrose synthase was investigated. Since turgor pressure is an important force driving cell elongation, the role of a water-channel protein (gammaTIP) was studied in relation to these two enzymes. The mRNA level of the invertase found was substantially up-regulated as a result of cold treatment. Analysis of the amino acid sequence of this invertase revealed the presence of a vacuolar targeting signal. Two different forms of sucrose synthase were found, the expression of one of them appeared to be restricted to the vascular tissue while the other form was present in the surrounding tissue. Both sucrose synthases were present in the stalk during the entire period of bulb storage and after planting, but their activities declined during stalk elongation. The expression of the gammaTIP gene was restricted mainly to the vascular tissue and its expression profile was identical to that of invertase. Simultaneous expression of invertase and gammaTIP possibly leads to an increase in osmotic potential and vacuolar water uptake, thus providing a driving force for stretching the stalk cells.

'Murasakizuisho' have a purple perianth except for the bottom region, which is blue in color even though it has the same anthocyanin, delphinidin 3-O-rutinoside, as the entire perianth. The development of the blue coloration in the perianth bottom is due to complexation by anthocyanin, flavonol and iron (Fe), as well as a vacuolar iron transporter, TgVit1. Although transient expression of TgVit1 in the purple cells led to a color change to light blue, the coloration of the transformed cells did not coincide with the dark blue color of the cells of the perianth bottom. We thought that another factor is required for the blue coloration of the cells of perianth bottom. To examine the effect of ferritin (FER), an Fe storage protein, on blue color development, we cloned an FER gene (TgFER1) and performed expression analyses. TgFER1 transcripts were found in the cells located in the upper region of the petals along with purple color development by anthocyanin and were not found in the blue cells of the perianth bottom. This gene expression is in contrast to that of TgVit1, expressed only in the cells of the perianth bottom. Co-expression of TgVIT1 and TgFER-RNAi, constructed for suppressing endogenous TgFER1 by RNA interference (RNAi), changed the purple petal cells to a dark blue color similar to that of the natural perianth bottom. These results strongly suggest that TgVit1 expression and TgFER1 suppression are critical for the development of blue color in the perianth bottom.

It has been suggested that sHSPs displaying chaperone-like properties may stabilize myofibrillar proteins during stress conditions and prevent them from loss of function. In the present study five sHSPs (alphaB-crystallin, MKBP, HSP25, HSP20, and <span class="hlt">cv</span>HSP) were investigated with respect to similarities and differences of their expression in heart and skeletal muscle under normal and ischemic conditions. In ischemic heart and skeletal muscle these five sHSPs translocated from cytosol to the Z-/I-area of myofibrils. Myofibrillar binding of all sHSPs was very tight and resisted for the most part extraction with 1 M NaSCN or 1 M urea. MKBP and HSP20 became extracted by 1 M NaSCN to a significant extent indicating that these two sHSPs may bind partially to actin-associated proteins which were completely extracted by this treatment. Ultrastructural localization of alphaB-crystallin showed diffuse distribution of immunogold label throughout the entire I-band in skeletal muscle fibers whereas in cardiomyocytes alphaB-crystallin was preferentially located at the N-line position of the I-band. These observations indicate different myofibrillar binding sites of alphaB-crystallin in cardiomyocytes versus skeletal muscle fibers. Further differences of the properties of sHSPs could be observed regarding fiber type distribution of sHSPs. Thus sHSPs form a complex stress-response system in striated muscle tissue with some common as well as some distinct functions in different muscle types.

AAA group, <span class="hlt">cv</span>. Brazilian) fruit postharvest ripening, four cDNAs encoding 14-3-3 proteins were isolated from banana and designated as Ma-14-3-3a, Ma-14-3-3c, Ma-14-3-3e, and Ma-14-3-3i, respectively. Amino acid sequence alignment showed that the four 14-3-3 proteins shared a highly conserved core structure and variable C-terminal as well as N-terminal regions with 14-3-3 proteins from other plant species. Phylogenetic analysis revealed that the four 14-3-3 genes belong to the non-? groups. They were differentially and specifically expressed in various tissues. Real-time RT-PCR analysis indicated that these four genes function differentially during banana fruit postharvest ripening. Three genes, Ma-14-3-3a, Ma-14-3-3c, and Ma-14-3-3e, were significantly induced by exogenous ethylene treatment. However, gene function differed in naturally ripened fruits. Ethylene could induce Ma-14-3-3c expression during postharvest ripening, but expression patterns of Ma-14-3-3a and Ma-14-3-3e suggest that these two genes appear to be involved in regulating ethylene biosynthesis during fruit ripening. No obvious relationship emerged between Ma-14-3-3i expression in naturally ripened and 1-MCP (1-methylcyclopropene)-treated fruit groups during fruit ripening. These results indicate that the 14-3-3 proteins might be involved in various regulatory processes of banana fruit ripening. Further studies will mainly focus on revealing the detailed biological mechanisms of these four 14-3-3 genes in regulating banana fruit postharvest ripening.
