Bermudagrass and Buffalograss Drought Response and Recovery at Two Soil Depths
Authors: Steinke K. , Chalmers D. , Thomas J. , White R. 
Published: April 2011

ABSTRACTDrought responsive turfgrass cultivars are becoming increasingly important in water conservation. Eight cultivars of bermudagrass [Cynodon dactylon (L.) Pers.], one cultivar of buffalograss [Buchloe dactyloides (Nutt.) Engelm.], and two root‐zone depths were evaluated for drought response and recovery during consecutive 60‐d drought and 60‐d recovery periods over 2 yr. Individual cultivar responses to drought and post‐drought recovery time were quantified through digital image analysis as the number of days to decrease to or increase to 50% green ground cover, respectively. No grass survived the 60‐d drought when planted on the restricted 10‐cm soil depth in 2006 or 2007, while all entries survived when planted on the unrestricted native soil depth. Both study years provided unique conditions for investigating drought response as the mean time to reach 50% green ground cover differed by 17 d between the 2 yr of study. Some cultivars lost 50% green ground cover in 20 d while other cultivars lasted the entire 60‐d drought period without losing 50% green ground cover. Post‐drought turfgrass recovery responses differed by as much as 45 d in achieving 50% green ground cover. Documenting individual cultivar responses to drought and recovery may provide perspective on individual grass cultivars that may initiate poor irrigation management behavior due to early leaf firing as well as refine consumer expectations following drought conditions.
Developing Cold‐Chipping Potato Varieties by Silencing the Vacuolar Invertase Gene

Published: April 2011

ABSTRACTAccumulation of reducing sugars during cold storage is a persistent and costly problem for the potato (Solanum tuberosum L.) processing industry. High temperature processing of potato tubers with elevated amounts of reducing sugars results in potato chips, fries, and other products that are unacceptable to consumers because of their bitter taste and unappealing dark color. More problematically, such products contain increased amounts of acrylamide, a neurotoxin and a potential carcinogen. We have demonstrated that silencing of the potato vacuolar acid invertase gene VInv can prevent reducing sugar accumulation in cold‐stored tubers. Using this approach we developed VInv silencing lines using RNA interference (RNAi) from four potato cultivars grown currently for potato chip production in North America. Accumulation of reducing sugars during cold storage was reduced by ∼93% or more in all RNAi lines that had >90% reduction of VInv transcript. Potato chips produced from these lines were light colored and significantly lower in acrylamide than controls. Changes in growth and tuber yield were not associated with VInv suppression using RNAi. We demonstrate that silencing of VInv is an effective approach to control the cold‐induced sweetening problem in potato.

ABSTRACTThe turf‐type bermudagrasses include diploidCynodon transvaalensisBurtt Davy, tetraploidC. dactylon(L.) Pers., and sterile triploid hybrids produced by crosses of these species. The objective of this study was to develop a set of microsatellite markers that could distinguish among commercially important turf‐type cultivars. A genomic library enriched for the [CA/GT]nrepeat motif was constructed from DNA of the ‘Tifway’ hybrid and sequenced to identify microsatellite regions. Twenty‐five microsatellite‐flanking primer sets were developed and used to genotype two plant introductions and 12 turf‐type cultivars. These primer sets produced an average of 10 amplicons across the 14 DNA templates. Sequences of selected amplicons revealed polymorphism resulting from expansion and/or contraction of the microsatellite and from indel mutations in the microsatellite flanking regions. As few as two primer sets were sufficient to differentiate all unrelated introduction lines and cultivars. The primer sets failed to distinguish among closely related cultivars developed by selection of natural variants, but one primer set uniquely distinguished the cultivar TifEagle from its irradiated parent cultivar. These genomic microsatellites were not derived from gene coding sequences and will supplement the existing expressed sequence tag (EST)‐based bermudagrass microsatellites. They will be most useful for evaluating the genetic diversity ofCynodonaccessions and distinguishing among cultivars that exploit this diversity.
GGE Biplot Exploration of Resistance to Sheath Blight Disease in Doubled‐Haploid Lines of Rice

Published: April 2011

ABSTRACTDevelopment of cultivars resistant to sheath blight (SB) disease caused by Rhizoctonia solani Kuhn is an important breeding objective for the southern U.S. rice (Oryza sativa L.) industry. The aim of this research was to explore performance, genotype (G) and genotype × environment (GE) interactions, and stability for SB resistance of 322 doubled‐haploid (DH) lines of the SB2 mapping population produced by the RiceCAP project. Analysis was performed by heritability‐adjusted genotype plus genotype × environment interaction (HA‐GGE) biplot analysis, Hühn's nonparametric stability statistics, median polish, and additive main effects and multiplicative interaction (AMMI). Genetic material was evaluated in replicated plots for 2 yr (2006 and 2007) in Louisiana and Arkansas. A single mega‐environment was identified consisting of the four year–location combinations. Heritability‐adjusted genotype plus genotype × environment interaction biplot analyses identified 11 DH lines with high and stable levels of resistance at both locations. Five susceptible DH lines were also identified with greater stability than the susceptible parent used to develop the SB2 population. Results from Hühn's nonparametric approach and median polish complemented those of HA‐GGE biplot analysis. Material identified in this study represents a potential source of high and stable SB resistance for cultivar development that warrants additional field‐plot evaluation.

OBJECTIVE
To determine the individual persistence of the relationship between mean sensor glucose (MG) concentrations and hemoglobin A1c (A1C) from the Juvenile Diabetes Research Foundation Continuous Glucose Monitoring (CGM) Randomized Trial.

RESEARCH DESIGN AND METHODS
MG was calculated using CGM data for 3 months before A1C measurements at 3, 6, 9, and 12 months for the CGM group and at 9 and 12 months for the control group. An MG-to-A1C ratio was included in analysis for subjects who averaged ≥4 days/week of CGM use.

RESULTS
Spearman correlations of the MG-to-A1C ratio between consecutive visits 3 months apart ranged from 0.70 to 0.79. The correlations for children and youth were slightly smaller than those for adults. No meaningful differences were observed by device type or change in A1C.

CONCLUSIONS
Individual variations in the rate of hemoglobin glycation are persistent and contribute to the inaccuracy in estimating MGs calculated from A1C levels.

Abstract
A sequence (f

n: X → ℝ almost decreases (increases) to a function f: X → ℝ if it pointwise converges to f and for each point x ∈ X there is a positive integer n(x) such that f
n+1(x) ≤ f
n (x) (f
n+1(x) ≥ f
n(x)) for n ≥ n(x). In this article I investigate this convergence in some families of continuous functions.

Published: April 2011

AbstractWe present a theoretical analysis of the quantum efficiency of a resonant cavity enhanced InGaAs/GaAs p-i-n photodetector (PD) for the ultrashort optical connections. The numerical method of calculation of quantum efficiency combining a transfer matrix method and an energy conservation law is offered. Using anomalous dispersion (AD) mirror, flat-topped QE spectrum has been obtained. Conditions for ideal flat-topped spectral response have been received. A design with a maximum QE of 93.5% and 3-nm bandwidth at 0.02 dB below the peak is presented.
Rimbaud et Corbière se sont-ils lus ?
Authors: Ischi Stéphane 
Published: April 2011

Cet article met en avant les nombreuses correspondances qu’entretiennent les poèmes d’Arthur Rimbaud et de Tristan Corbière. Dans la plupart des cas, aucun des deux auteurs n’avait connaissance du travail de l’autre au moment de la rédaction de son texte. Un fait retiendra spécifiquement notre attention : les analogies les plus troublantes avec Les Amours jaunes de Corbière se trouvent dans des œuvres de Rimbaud qui ne nous sont connues que par des manuscrits de la main de Verlaine, peut-être réécrits de mémoire bien après leur date de création. La fiabilité de ces « copies » verlainiennes est incertaine et fait l’objet de débats au sein de la critique rimbaldienne. Dans ce contexte, les « échos » corbiériens, au sein de poèmes de Rimbaud, pourraient être le signe d’une intervention de Verlaine dans les textes qu’il nous transmet. L’article constate à quel point les deux poètes semblent se mêler dans l’esprit de Verlaine, par exemple lorsqu’il les évoque dans ses Poètes maudits .
Interprétations croisées franco-russes du régime politique en Russie
Authors: Lapina Nathalia 
Published: April 2011

Résumé Le passé historique peut-il expliquer le présent ? C’est un problème que se posent les spécialistes de la Russie contemporaine tant en France qu’en Russie. Les interprétations du régime politique postcommuniste sont fortement influencées par la lecture de l’histoire russe. Les objections formulées à l’égard de cette approche sont nombreuses : vision droitière lorsque l’histoire se projette sur le présent et même sur le futur, déterminisme, remplacement de la réalité politique et sociale par le passé historique. Une question reste à poser : comment intégrer les connaissances du passé dans la réflexion sur le monde contemporain ? L’approche historique est pertinente à condition que le chercheur ne se concentre pas uniquement sur le passé mais donne une image de la réalité politique, de la situation unique que nous vivons ici et maintenant.
Les socialistes, la Banque de France et le « mur d'argent » (1981-1984)
Authors: Duchaussoy Vincent 
Published: April 2011

Résumé Cet article examine l’existence d’une opposition financière à l’exercice du pouvoir par les socialistes en France, pendant les trois premières années du premier septennat de François Mitterrand. Cette idée a déjà été exprimée sous l’expression de « mur d’argent », dont la réalité a été démontrée pour les expériences du Cartel des gauches et du Front populaire. Toutefois, la question restait entière pour la période des années 1980. Vincent Duchaussoy explicite les mythes et réalités de ce « mur d’argent » dans le contexte singulier de ces premières « années Mitterrand ». Une place particulière est accordée à l’étude du rôle de la Banque de France, qui fut dans les années 1920 la figure de proue de cette opposition financière. L’étude des rapports entre la Banque et l’État, principalement à travers la direction du Trésor, est un prisme éclairant pour l’histoire naissante de ces années 1980.
Secretive Marsh Bird Species Co-Occurrences and Habitat Associations Across the Midwest, USA
Authors: Bolenbaugh Jason R. , Krementz David G. , Lehnen Sarah E. 
Published: April 2011

AbstractBecause secretive marsh birds are difficult to detect, population status and habitat use for these birds are not well known. We conducted repeated surveys for secretive marsh birds across 264 sites in the Upper Mississippi River and Great Lakes Joint Venture region to estimate abundance, occupancy, and detection probabilities during the 2008 and 2009 breeding seasons. We identified species groups based on observed species co-occurrences. Two species, least bittern Ixobrychus exilis and American bittern Botaurus lentiginosus, co-occurred with other species less often than expected by chance, and two species groups, rails (Virginia rail Rallus limicola and sora Porzana carolina) and open-water birds (pied-billed grebe Podilymbus podiceps, common moorhen Gallinula chloropus, and American coot Fulica americana; coots were only surveyed in 2009), co-occurred more often than expected by chance. These groupings were consistent between years. We then estimated the relation of these species and groups to landscape and local site characteristics by using zero-inflated abundance models that accounted for incomplete detection. At the landscape level (5-km radius), the amount of emergent herbaceous wetland was positively associated with least bittern occupancy, whereas the amount of woody wetland was negatively associated with least bittern, rail, and open-water bird occupancy. At the local level, habitat variables that were associated with abundance were not consistent among groups or between years, with the exception that both least bitterns and open-water birds had a strong positive association between abundance and water–vegetation interspersion. Land managers interested in marsh bird management or conservation may want to consider focusing efforts on landscapes with high amounts of emergent herbaceous wetland and low amounts of woody wetland, and managing for high amounts of water–vegetation interspersion within the wetland.
Painful Pathways Induced by TLR Stimulation of Dorsal Root Ganglion Neurons

Published: April 2011

AbstractWe hypothesize that innate immune signals from infectious organisms and/or injured tissues may activate peripheral neuronal pain signals. In this study, we demonstrated that TLRs 3, 7, and 9 are expressed by human dorsal root ganglion neurons (DRGNs) and in cultures of primary mouse DRGNs. Stimulation of murine DRGNs with TLR ligands induced expression and production of proinflammatory chemokines and cytokines CCL5 (RANTES), CXCL10 (IP-10), IL-1α, IL-1β, and PGE2, which have previously been shown to augment pain. Further, TLR ligands upregulated the expression of a nociceptive receptor, transient receptor potential vanilloid type 1 (TRPV1), and enhanced calcium flux by TRPV1-expressing DRGNs. Using a tumor-induced temperature sensitivity model, we showed that in vivo administration of a TLR9 antagonist, known as a suppressive oligodeoxynucleotide, blocked tumor-induced temperature sensitivity. Taken together, these data indicate that stimulation of peripheral neurons by TLR ligands can induce nerve pain.

Abstract
Mouse dendritic cells (DC) have been extensively studied in various tissues, especially spleen, and they comprise subsets with distinct developmental origins, surface phenotypes, and functions. Considerably less is known about human DC due to their rarity in blood and inaccessibility of other human tissues. The study of DC in human blood has revealed four subsets distinct in phenotype and function. In this study, we describe four equivalent DC subsets in human spleen obtained from deceased organ donors. We identify three conventional DC subsets characterized by surface expression of CD1b/c, CD141, and CD16, and one plasmacytoid DC subset characterized by CD304 expression. Human DC subsets in spleen were very similar to those in human blood with respect to surface phenotype, TLR and transcription factor expression, capacity to stimulate T cells, cytokine secretion, and cross-presentation of exogenous Ag. However, organ donor health status, in particular treatment with corticosteroid methylprednisolone and brain death, may affect DC phenotype and function. DC T cell stimulatory capacity was reduced but DC were qualitatively unchanged in methylprednisolone-treated deceased organ donor spleen compared with healthy donor blood. Overall, our findings indicate that human blood DC closely resemble human spleen DC. Furthermore, we confirm parallels between human and mouse DC subsets in phenotype and function, but also identify differences in transcription factor and TLR expression as well as functional properties. In particular, the hallmark functions of mouse CD8α+ DC subsets, that is, IL-12p70 secretion and cross-presentation, are not confined to the equivalent human CD141+ DC but are shared by CD1b/c+ and CD16+ DC subsets.
Endoscopic ultrasound-guided fine-needle aspiration of metastases to the pancreas: A study of 25 cases
Authors: Gilbert Christopher M. , Monaco Sara E. , Cooper Scott T. , Khalbuss Walid E. 
Published: April 2011

Background:
Metastases to the pancreas are an uncommon cause of pancreatic masses seen on endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA). The purpose of this study is to retrospectively review the cytomorphology, clinical findings, and results of ancillary studies in a large series of these unusual cases.

Materials and Methods:
We searched our institution's pathology database for EUS-guided FNAs of the pancreas that were diagnostic of metastatic tumor over a 5-year period. The final cytologic diagnosis, results of ancillary studies, corresponding histological material, and clinical follow-up data were reviewed in these cases.

Results:
A total of 1172 pancreatic EUS-guided FNAs were identified, of which 25 cases (2.1%) had a confirmed diagnosis of a pancreatic metastasis. This included 12 (48%) cases of renal cell carcinoma, 3 (12%) melanomas, 3 (12%) small cell carcinomas, and 7 (28%) other malignancies. In these metastatic tumors involving the pancreas, 20 (80%) of the lesions were solitary. Four (16%) cases had no prior history of malignancy. The average time to diagnosis of pancreatic metastasis was 5.3 years. Immunohistochemistry and special stains were performed in 22 (88%) and 9 (36%) cases, respectively.

Conclusions:
Our data shows that although metastases to the pancreas are rare, they can present as a solitary mass many years after the primary malignancy is diagnosed and can even be the first manifestation of an extrapancreatic primary in a small number of cases. It is important to consider the possibility of a metastatic lesion in the pancreas because this may require a different management than a primary pancreatic tumor.
Effects of erosion control practices on runoff, soil loss, and yield of strawberries in the Lower Fraser Valley
Authors: Vliet L. J. P. van , Hall J. W. , Fast D. 
Published: April 2011

Erosion control practices were evaluated for their ability to reduce soil loss and runoff and for their effects on strawberry (Fragaria × ananassa Duch.) yield on a silt loam soil in the uplands area of the Lower Fraser Valley. Three treatments (underdrainage, winter cover cropping of barley [Hordeum vulgare L.] and cross slope planting) were compared to a control. Soil and runoff losses from natural rainfall were measured on replicated experimental plots (0.01375 ha) from 1991 to 1994. Soil and runoff losses were significantly lower with the winter cover crop and cross-slope planting treatments than the control. Results for the underdrainage treatment were not significantly different from the control and non-representative of proper underdrainage due to too deep an installation under wet conditions. Soil protection by the barley cover crop reduced mean annual soil loss and runoff by 78 and 43%, respectively. Cross slope planting reduced soil and runoff losses by 97 and 84%, respectively, compared with the control. Annual runoff coefficients of up to 21% were observed for the control, while coefficients of 40% were not uncommon for single storm events. Except for the cross slope treatment, strawberry yields were not compromised by the erosion control practices. Winter cover cropping is the preferred erosion control practice for strawberries grown on upland soils, since cross slope planting may cause depressed yields from root rot disease resulting from stagnant water between the rows. Key words: Soil loss, runoff, runoff coefficient, cover crop, across slope, erosion control
Continuous Blood Purification Ameliorates RhoA-Mediated Endothelial Permeability in Severe Acute Pancreatitis Patients with Lung Injury

Published: April 2011

Background In the early phase of severe acute pancreatitis (SAP), serious pulmonary complications which are directly correlated with mortality are very common. Endothelial injury has been shown to play a key role in the pathogenesis of ALI/ARDS. Continuous blood purification (CBP) has been widely used in treating patients with multiple organ dysfunction syndrome (MODS) including ARDS. However, the impact of CBP on endothelial function has been little studied. Methods Human umbilical vein endothelial cells (HUVECs) were exposed to serum samples or replacement fluid taken from patients at specific time points during CBP, or pretreated with Y-27632 followed by treatment with serum, then, changes in cytoskeletal configuration, endothelial monolayer permeability, and RhoA activation were studied. Results Endothelial permeability, RhoA activity, and stress fiber reorganization increased in HUVECs treated with serum from patients before CBP initiation, and lessened in HUVECs treated with serum from patients after CBP initiation. Endothelial hyperpermeability and stress fiber reorganization reduced in HUVECs pretreated with Rho-kinase inhibitor, Y-27632, and in a dose-dependent fashion. Endothelial permeability and RhoA activity increased in HUVECs treated with waste replacement fluid collected 2 h after CBP initiation. Conclusions After CBP treatment, endothelial hyperpermeability induced by serum from SAP patients with lung injury was reduced. The inhibition of RhoA-mediated F-actin remodeling might be the mechanism.
