This study was conducted to evaluate if coronary microvascular function is impaired in such patients. Coronary hemodynamic studies and head-up tilt table tests (HUTs) were performed on 30 consecutive patients with normal coronary angiograms and recurrent syncope. Another ten subjects with atypical chest pain and no evidence of myocardial ischemia or syncope served as a control. Great cardiac vein flow (GCVF) and coronary sinus flow (CSF) were measured by the thermodilution method at baseline and after dipyridamole infusion (0.56 mg/kg IV for 4 minutes). Coronary flow reserve (CFR), derived from CSF and GCVF, was significantly lower in the 15 patients with positive HUT than in the other 15 patients with negative HUT (1.75 ± 0.48vs2.64 ± 0.8, P < 0.01and2.29 ± 0.45vs3.07 ± 0.63, P < 0.01, respectively). Ischemic-like ECG was noted during treadmill exercise test in 40% of the former and in 7% of the latter group(P = 0.01). There was no significant difference in CFR between patients with negative HUT and control subjects. Coronary microvascular function was impaired in syncopal patients with positive HUT and relatively preserved in those with negative HUT, suggesting the possible linkage between coronary microvascular dysfunction and the development of neurally mediated syncope.

Triggering the significant-other representation should also indirectly activate any self-discrepancy held from this other's perspective, resulting in shifts in discrete affect and self-regulation. Participants (n,=,110; 34 men, 76 women) with an actual-ideal or actual-ought self-discrepancy from their parent's perspective (Higgins, 1987) learned about a new person who did or did not minimally resemble this parent. As predicted, this evoked positive evaluation of the new person, that is, a positive transference, and yet, as a function of self-discrepancy, also increased discrete negative mood with ideal-discrepant individuals becoming more dejected and ought-discrepant individuals more hostile and less calm. Self-regulatory focus shifted as well in terms of motivation to avoid emotional closeness. Copyright © 2007 John Wiley & Sons, Ltd.

[source] Using evidence for population stratification bias in combined individual- and family-level genetic association analyses of quantitative traitsGENETIC EPIDEMIOLOGY, Issue 5 2010Lucia Mirea Abstract Genetic association studies are generally performed either by examining differences in the genotype distribution between individuals or by testing for preferential allele transmission within families. In the absence of population stratification bias (PSB), integrated analyses of individual and family data can increase power to identify susceptibility loci [Abecasis et al., 2000. Am. J. Hum. Genet. 66:279,292; Chen and Lin, 2008. Genet. Epidemiol. 32:520,527; Epstein et al., 2005. Am. J. Hum. Genet. 76:592,608]. In existing methods, the presence of PSB is initially assessed by comparing results from between-individual and within-family analyses, and then combined analyses are performed only if no significant PSB is detected. However, this strategy requires specification of an arbitrary testing level ,PSB, typically 5%, to declare PSB significance. As a novel alternative, we propose to directly use the PSB evidence in weights that combine results from between-individual and within-family analyses. The weighted approach generalizes previous methods by using a continuous weighting function that depends only on the observed P -value instead of a binary weight that depends on ,PSB. Using simulations, we demonstrate that for quantitative trait analysis, the weighted approach provides a good compromise between type I error control and power to detect association in studies with few genotyped markers and limited information regarding population structure.

[source] Analytical Methods for Transient Flow to a Well in a Confined-Unconfined AquiferGROUND WATER, Issue 4 2008Li-Tang Hu Concurrent existence of confined and unconfined zones of an aquifer can arise owing to ground water withdrawal by pumping. Using Girinskii's potential function, Chen (1974, 1983) developed an approximate analytical solution to analyze transient ground water flow to a pumping well in an aquifer that changes from an initially confined system to a system with both unconfined and confined regimes. This article presents the details of the Chen model and then compares it with the analytical model developed by Moench and Prickett (1972) for the same problem. Hypothetical pumping test examples in which the aquifer undergoes conversion from confined to water table conditions are solved by the two analytical models and also a numerical model based on MODFLOW. Comparison of the results suggests that the solutions of the Chen model give better results than the Moench and Prickett model except when the radial distance is very large or aquifer thickness is large compared with drawdown.

[source] PCR-BASED TECHNIQUE FOR IDENTIFICATION AND DETECTION OF TRICHOGRAMMA SPP. (HYMENOPTERA: TRICHOGRAMMATIDAE) WITH SPECIFIC PRIMERSINSECT SCIENCE, Issue 3 2002LI Zheng-xi Abstract The rDNA-ITS2 regions of T. dendrolimi Matsumura and T. ostriniae Pang et Chen (Hymenoptera: Trichogrammatidae) were cloned and sequenced. The homologous sequences available in GenBank were retrieved and analyzed, and then specific primers were designed for molecular identification and detection of T. dendrolimi. Repeated screening showed that PCR amplification by the diagnostic primers enabled the differentiation of not only bulk samples and single adult (male or female), but also eggs and juveniles, which was not possible by conventional methods. The advantage of this system over morphology-based systems is that non-specialists are able to identify individuals or trace specimens efficiently. The derived molecular detection technique was then used to identify 12 specimens collected from different localities on the Chinese mainland; the results showed that this protocol could be applied to molecular monitoring of Trichogramma species in the field. Finally, 1132s of 6 geographical populations of T. dendrolimi (TdCHA, TDJL, TdXZ, TdKH, TdCZ and TdYBL) were cloned and sequenced. The multialignment analysis of intraspecific ITS2 sequences showed that the diagnostic primers have their own theoretical bases.

[source] Sample geometry effects on incoherent small-angle scattering of light waterJOURNAL OF APPLIED CRYSTALLOGRAPHY, Issue 1 2000F. Carsughi Light water is frequently used as a standard for calibrating small-angle neutron scattering (SANS) data. The intensities collected for 1 and 2,mm of light water in standard quartz cells may differ by up to about 50% due to the presence of multiple and inelastic scattering [Rennie & Heenan (1993). Proceedings of ISSI Meeting, Dubna, pp. 254,260, Report E3-93-65; Teixeira (1992). Structure and Dynamics of Strongly Interacting Colloids and Supramolecular Aggregates in Solution, edited by S. H. Chen, pp. 625,658. Dordrecht: Kluwer Academic Publishers]. Multiple scattering increases with the thickness of the sample. The use of only elastically scattered neutrons may lead to an absolute intensity of the SANS data of about a factor of 2 higher than that obtained by taking into account all of the neutrons on the detector [Ghosh & Rennie (1990). Inst. Phys. Conf. Ser.107, 233,244]. However, it is shown here that the scattering intensities collected with different ratios of sample-to-beam dimension do present large differences as a function of sample thickness. In particular, ratios smaller and larger than unity are considered and the results are discussed and compared with Monte Carlo simulations.

[source] Is it a short-memory, long-memory, or permanently Granger-causation influence?JOURNAL OF FORECASTING, Issue 7 2008Wen-Den ChenArticle first published online: 6 JUN 200 Abstract Exploring the Granger-causation relationship is an important and interesting topic in the field of econometrics. In the traditional model we usually apply the short-memory style to exhibit the relationship, but in practice there could be other different influence patterns. Besides the short-memory relationship, Chen (2006) demonstrates a long-memory relationship, in which a useful approach is provided for estimation where the time series are not necessarily fractionally co-integrated. In that paper two different relationships (short-memory and long-memory relationship) are regarded whereby the influence flow is decayed by geometric, or cutting off, or harmonic sequences. However, it limits the model to the stationary relationship. This paper extends the influence flow to a non-stationary relationship where the limitation is on ,0.5 , d , 1.0 and it can be used to detect whether the influence decays off (,0.5 , d < 0.5) or is permanent (0.5 , d , 1.0).

Koch (,Wugong'), the beetle Mylabris phalerata Pallas (,Ban mao') and the earthworm Pheretima aspergillum Chen (,DiLong') have a reputation in traditional Chinese medicine for reducing symptoms of central nervous system decline, including memory loss. A series of extracts of all three organisms was tested for acetylcholinesterase (AChE) inhibition and copper ion binding effects, the latter likely to reduce oxidative damage caused by excess copper. The beetle and centipede chloroform extracts showed the strongest AChE inhibitory effects (30.6% inhibition at 105 ,g mL,1 and 32.3% inhibition at 167 ,g mL,1, respectively) and, in the case of the centipede, this was traced to the unsaturated fatty acids present using bioassay-guided fractionation. Cantharidin from the beetle was shown to have AChE activity (31% inhibition at 1 ,M, 0.196,g mL,1), making it a major contributor to the activity of the beetle extract. The earthworm showed no AChE inhibitory activity. Since unsaturated fatty acids have not been previously reported to have AChE inhibitory activity, a series of related compounds was tested to determine structure-activity relationships. It was found that activity existed where there was a chain length of more than 16 C atoms with at least one unsaturated bond in the chain. The carboxylic acid group was also necessary for activity. The fatty acids present in the centipede also showed the ability to bind copper ions when tested using a novel thin layer chromatography method designed to detect copper-binding compounds. The activities reported give some support to the use of the beetle and centipede in traditional Chinese medicine for improving cognitive function.

R. China; 5The University of Georgia, Athens, GA 30602-3636, USA One of the most difficult tasks resource managers face is understanding the carrying capacity of coastal waters for aquaculture. Aquaculture, like many other human activities, can threaten coastal waters. Aquaculture producing shrimp and finfish depends on supplemental feeding and can contribute to eutrophication. A second type, involving shellfish and macroalgae, extracts plankton and nutrients from surrounding waters, and can have a significant positive impact on moderately eutrophic waters. Ecosystem modeling offers a 3-dimensional physical, chemical and biological simulation that can help understand and predict the impacts of aquaculture on coastal embayments. Such a model is being explored for Xincun Bay (22 km2), which is located in southeastern Hainan Province, China. Aquaculture in Xincun Bay includes 6500 fish pens, 100 ha of shrimp ponds, pearl oyster culture rafts and Kappaphycus alvarezii culture that produces 2,000 mt (Oct.-May). The surrounding area has ~ 15,000 people and Xincun City is a major offshore fishing and tourist center. The annual nitrogen and phosphorus removal capacity of Kappaphycus in Xincun Bay may have been in the order of 53.8 and 3.7 mt, respectively, during the 1999-2000 growing season. Lian Bay (~ 15 km2), a nearby bay with only Kappaphycus and pearl oyster culture (and little anthropogenic input), has a macroalgal production of 1,500 mt annually. The annual nitrogen and phosphorus removal capacity of Kappaphycus here may have been in the order of 25 and 0.33 mt, respectively. Our prototype model may hold the promise for showing the importance of integrating seaweed culture activities in the maintenance and health of coastal embayments. [source] Functional Coefficient Autoregressive Models: Estimation and Tests of HypothesesJOURNAL OF TIME SERIES ANALYSIS, Issue 2 2001Rong Chen In this paper, we study nonparametric estimation and hypothesis testing procedures for the functional coefficient AR (FAR) models of the form Xt=f1(Xt,d)Xt, 1+ ... +fp(Xt,d)Xt,p+,t, first proposed by Chen and Tsay (1993). As a direct generalization of the linear AR model, the FAR model is a rich class of models that includes many useful parametric nonlinear time series models such as the threshold AR models of Tong (1983) and exponential AR models of Haggan and Ozaki (1981). We propose a local linear estimation procedure for estimating the coefficient functions and study its asymptotic properties. In addition, we propose two testing procedures. The first one tests whether all the coefficient functions are constant, i.e. whether the process is linear. The second one tests if all the coefficient functions are continuous, i.e. if any threshold type of nonlinearity presents in the process. The results of some simulation studies as well as a real example are presented. [source] Anti- Helicobacter pylori activity of Chinese tea: in vitro studyALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 5 2000Yuk-Kei Yee Background: Chinese tea has an antibacterial activity against a wide range of bacteria. However, its activity against Helicobacter pylori has not been reported. Method: In this study the anti- Helicobacter pylori effects of a Chinese tea (Lung Chen tea), and two tea catechins, epigallocatechin gallate and epicatechin and their minimum inhibitory concentrations (MICs) were examined. The effect of Lung Chen on metronidazole resistance was also studied using the E -test. Results: Lung Chen, epigallocatechin gallate and epicatechin all inhibited the growth of H. pylori. The MIC90 for Lung Chen was 0.25,0.5% (w/w) and that of epigallocatechin gallate and epicatechin were 50,100 and 800,1600 ,g/mL, respectively. Epigallocatechin gallate is probably the active ingredient responsible for most of the anti- H. pylori activity of Chinese tea. Lung Chen did not reverse metronidazole resistance. Conclusions: Chinese tea has anti- H. pylori activity in a daily consumed concentration, and epigallocatechin gallate is probably the active ingredient responsible for the action.

Chandrasekar Abstract Chen and Bhattacharyya [Exact confidence bounds for an exponential parameter under hybrid censoring, Commun Statist Theory Methods 17 (1988), 1857,1870] considered a hybrid censoring scheme and obtained the exact distribution of the maximum likelihood estimator of the mean of an exponential distribution along with an exact lower confidence bound. Childs et al. [Exact likelihood inference based on Type-I and Type-II hybrid censored samples from the exponential distribution, Ann Inst Statist Math 55 (2003), 319,330] recently derived an alternative simpler expression for the distribution of the MLE. These authors also proposed a new hybrid censoring scheme and derived similar results for the exponential model. In this paper, we propose two generalized hybrid censoring schemes which have some advantages over the hybrid censoring schemes already discussed in the literature. We then derive the exact distribution of the maximum likelihood estimator as well as exact confidence intervals for the mean of the exponential distribution under these generalized hybrid censoring schemes. © 2004 Wiley Periodicals, Inc.

(Fagaceae) from China: based on morphological and molecular dataNORDIC JOURNAL OF BOTANY, Issue 2 2009Li Chen The taxonomic position of Castanopsis longzhouica C. C. Huang & Y. T. Chang has been controversial. Various authors included it in Castanopsis (D. Don) Spach, or Lithocarpus Bl. based on morphology, palynology and wood anatomy. In order to investigate this issue, sequences of nuclear ITS and the chloroplast genes matK and trnL-F of C. longzhouica were analyzed together with 72 representatives of 7 genera within Fagaceae. As for species of Lithocarpus, there were a 1-bp insertion and two unique 3-bp deletions from ITS2 of C. longzhouica distinguishing it from Castanopsis. The phylogenetic analyses on the separate ITS data and the joint data (ITS+matK+ trnL-F) strongly supported a derived position of C. longzhouica within a clade consisting of members of Lithocarpus. The result is consistent with previous suggestions based on wood anatomy, suggesting that C. longzhouica should be transferred to Lithocarpus. In addition, the shallow cup-shaped, loose incoherent-scale and indehiscent cupule and the concave scar of C. longzhouica suggests a close relationship to species of Lithocarpus. Based on these data, the new combination Lithocarpus longzhouicus (C. C. Huang & Y. T. Chang) J. Q. Li & L. Chen is proposed. [source] A NEW SPINICAUDATAN GENUS (CRUSTACEA: ,CONCHOSTRACA') FROM THE LATE CRETACEOUS OF MADAGASCARPALAEONTOLOGY, Issue 5 2008ALYCIA L. STIGALL Abstract:, A new spinicaudatan genus and species, Ethmosestheria mahajangaensis gen. et sp. nov., is described from the Anembalemba Member (Upper Cretaceous, Maastrichtian) of the Maevarano Formation, Mahajanga Basin, Madagascar. This is the first spinicaudatan reported from the post-Triassic Mesozoic of Madagascar. The new species is assigned to the family Antronestheriidae based on the cavernous or sievelike ornamentation on the carapace. Of well-documented Mesozoic spinicaudatan genera, Ethmosestheria mahajangaensis is most closely related to Antronestheria Chen and Hudson from the Great Estuarine Group (Jurassic) of Scotland. However, relatively poor documentation of the ornamentation of most Gondwanan Mesozoic spinicaudatan species precludes detailed comparison among taxa. Ethmosestheria mahajangaensis exhibits ontogenetic trends in carapace growth: a change in carapace outline from subcircular/subelliptical to elliptical, and from very wide juvenile growth bands to narrow adult growth bands. Ornamentation style, however, does not vary with ontogeny. Ethmosestheria mahajangaensis individuals lived in temporary pools in a broad channel-belt system within a semiarid environment; preserved desiccation structures on carapaces indicate seasonal drying out of pools within the river system. Specimens of Ethmosestheria mahajangaensis are preserved with exquisite detail in debris flow deposits; these are the first spinicaudatans reported from debris flow deposits. These deposits also contain a varied vertebrate fauna, including dinosaurs, crocodyliforms, turtles, and frogs. Rapid entombment of the spinicaudatan carapaces likely promoted early fossil diagenesis leading to highly detailed preservation.

Woodside Consumer researchers describe Heider's (1958) balance theory without showing how the theory relates to recent theoretical developments in consumer behavior. Empirical examination of the theory is also lacking in consumer-psychology literature. This article updates Heider's balance theory in consumer behavior by developing the theory's links to theories of perceptual, attitudinal, and behavior automaticity and controlled thinking (see Bargh, 1994; Bargh, Chen, & Burrows, 1996) and cognitive-experiential self-theory (Epstein, 1994). Propositions central for applying balance theory to consumer psychology link automatic-controlled memory retrievals and storytelling of unbalanced (i.e., paradoxical) situations that stimulate further thinking and action. Research using storytelling (e.g., see Fischer, 1999; Schank, 1990) methods aids in examining these theory developments empirically. © 2001 John Wiley & Sons, Inc.
