Comparison of the clinical significance of the Papanicolaou test interpretations LSIL cannot rule out HSIL and ASC‐H
Authors: Difurio Megan J. , Mailhiot Thomas , Sundborg Michael J. , Nauschuetz Karen K. 
Published: October 2009

AbstractDespite the two‐tiered classification of dysplasia in The Bethesda System (TBS), rare cases fall into the category squamous intraepithelial lesion (SIL) of indeterminate grade. These Pap tests are often interpreted as “LSIL/ASC‐H” or “LSIL” with a comment indicating the presence of cells with features approaching HSIL. Patients with LSIL/ASC‐H have a significant risk of CIN 2 or worse (29–61.5%) on follow‐up cervical biopsies, similar to the risk of CIN 2 or worse in patients with ASC‐H Pap tests (24–68%). The purpose of this study was to compare patients with ASC‐H and LSIL/ASC‐H Pap tests. Women with LSIL/ASC‐H had a slightly lower incidence of CIN 2 or worse (PPV = 35.6%, 95% CI: 29.8–41.4%) on follow‐up cervical biopsy than the control ASC‐H group (PPV = 40.2%, 95% CI: 31.9–56.3%); this difference was not statistically significant. The difference in the distribution of the biopsy results between the two groups was statistically significant (P < 0.001). The current guidelines for the management of cervical cytologic abnormalities from the American Society for Colposcopy and Cervical Pathology (ASCCP) advocate similar treatment algorithms for both LSIL and ASC‐H. The main difference is the option of cytologic follow‐up or HPV testing for certain “special populations,” as an alternative to colposcopy, for LSIL Pap test results. Based on our results, we recommend (1)LSIL/ASC‐H to be added to TBS classification and (2) Pap test cases of LSIL/ASC‐H may need to be clinically followed in a manner similar to ASC‐H, i.e., colposcopy for all patients.

Published: October 2009

AbstractIn the course of the synthesis of new fluorophores for molecular recognition an experimental (1H NMR) and theoretical (DFT) study of the ring‐chain isomerism of 3‐(pyridin‐2‐yl)[1,2,3]triazolo[1,5‐a]quinoline derivatives (A) into 2‐([1,2,3]triazolo[1,5‐a]pyridin‐3‐yl)quinoline derivatives (B) has been carried out. The rearrangement is influenced by steric and electronic effects of the substituents present on the quinoline ring. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
The impact of snowmelt and heavy rainfall runoff on erosion rates in a gully system, Lublin Upland, Poland
Authors: Rodzik Jan , Furtak Tomasz , Zglobicki Wojciech 
Published: October 2009

AbstractThe study examines water runoff and geomorphic processes within a permanent gully located in an agricultural catchment of the Lublin Upland, southeast Poland. The studies were conducted in the period 2003 to 2006, during which time the volume and intensity of precipitation were recorded and water runoff and sediment concentration at the outlet of the main gully were measured. After large surface runoff events that resulted in geomorphic effects, erosion and accumulation forms were examined. The role of snowmelt and heavy rains in the runoff of water and suspended solids from the catchment, as well as their effect on the dynamics of certain processes such as rill erosion, piping and accumulation within the gully all were evaluated. It was observed that the gully developed spatially through piping and headcut processes during snowmelt, while the main gully form became shallower as a result of accumulation processes. Headcut erosion at the gully bottom and transport of the material out of the catchment, predominantly during pluvial runoff events, were much less intensive. It was estimated that the intensity of snowmelt runoff in the years 2003 to 2006 was similar to the multi‐annual average, while the intensity of pluvial runoff was significantly lower. An attempt was made to describe the dynamics of gully erosion and the direction of gully system evolution on a medium‐term time scale (50 to 100 years). It was found that the roles of snowmelt and heavy rains in such catchments are in opposition. Snowmelt runoff events lead to the spatial development of the gullies and make them shallower, while pluvial runoff events add to the deepening of the gully and result in transporting the material outward. These two processes keep the gully system in relative balance. Copyright © 2009 John Wiley & Sons, Ltd.
Similar solutions of stretching flow with mass transfer
Authors: Hayat T. , Awais M. , Sajid M. 
Published: October 2009

AbstractThis study describes the influence of mass transfer on the steady two‐dimensional magnetohydrodynamic boundary layer flow of a Jeffery fluid bounded by a stretching sheet. A uniform magnetic field in the presence of chemical reaction is applied. The arising nonlinear partial differential equations are reduced to nonlinear ordinary differential equations by similarity variables. Similar solutions of velocity and concentration fields are derived by a homotopy analysis method. The values of surface mass transfer and gradient of mass transfer are also tabulated.

Accurate and efficient simulation of transport in multidimensional flow
Authors: Latorre B. , Garcia‐Navarro P. , Murillo J. , Burguete J. 
Published: October 2009

AbstractA new numerical method to obtain high‐order approximations of the solution of the linear advection equation in multidimensional problems is presented. The proposed conservative formulation is explicit and based on a single updating step. Piecewise polynomial spatial discretization using Legendre polynomials provides the required spatial accuracy. The updating scheme is built from the functional approximation of the exact solution of the advection equation and a direct evaluation of the resulting integrals. The numerical details for the schemes in one and two spatial dimensions are provided and validated using a set of numerical experiments. Test cases have been oriented to the convergence and the computational efficiency analysis of the schemes. Copyright © 2009 John Wiley & Sons, Ltd.

Authors: Zhou Shuchan , Huang Xiangfei , Cai Qinghua 
Published: October 2009

AbstractFrom July 2003 to June 2005, investigations of rotifer temporal and spatial distributions were car‐ried out in a bay of the Three Gorges Reservoir, Xiangxi Bay, which is the downstream segment of the Xiangxi River and the nearest bay to the Three Gorges Reservoir dam in Hubei Province, China. Thirteen sampling sites were selected. The results revealed a high species diversity, with 76 species, and 14 dominant species;i.e., Polyarthra vulgaris, Keratella cochlearis, Keratella valga, Synchaeta tremula, Synchaeta stylata, Trichocerca lophoessa, Trichocerca pusilla, Brachionus angularis, Brachionus calyciflorus, Brachionus forficula forficula, Ascomorpha ovalis, Conochilus unicornis, Ploesoma truncatum and Anuraeopsis fissa.After the first year of the reservoir impoundment, the rotifer community was dominated by ten species; one year later it was dominated by eight species. The community in 2003/2004 was dissimilar to that in 2004/2005, which resulted from the succes‐sion of the dominant species. The rotifer community exhibited a patchy distribution, with significant heterogeneity observed along the longitudinal axis. All rotifer communities could be divided into three groups, corresponding to the riverine, the transition and the lacustrine zone, respectively. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Food Resource Partitioning between Two Invasive Gobiid Species (Pisces, Gobiidae) in the Littoral Zone of the River Danube, Hungary
Authors: Borza Péter , Erős Tibor , Oertel Nándor 
Published: October 2009

AbstractAt present, the invasive round and bighead gobies are the most abundant benthic fish species in the near shore zone of the Middle Danube. We compared their diet seasonally in natural and artificial habitats and contrasted it with the food supply. The composition of the macroinvertebrate community was determined mainly by seasonal changes, whereas habitat type had smaller effect. Round gobies followed these changes flexibly. They consumed mainly chironomids in the spring, whilst amphipods and molluscs in the summer and autumn. Bighead gobies relied on amphipods in each season and in both habitats, and consumed fish, too, including round goby (intraguild predation). Diet overlap was determined by the morphological differences of the species allowing a varying degree of differentiation according to the seasonally changing food supply.

Temperature‐Dependent Growth and Life Cycle of Nemoura sichuanensis (Plecoptera: Nemouridae) in a Chinese Mountain Stream
Authors: Li Fengqing , Cai Qinghua , Liu Jiankang 
Published: October 2009

AbstractPlecoptera constitute a numerically and ecologically significant component in mountain streams all over the world, but little is known of their life cycles in Asia. The life cycle of Nemoura sichuanensis and its relationship to water temperature was investigated during a 4‐year study in a headwater stream (known as the Jiuchong torrent) of the Xiangxi River in Central China. Size structure histograms suggest that the life cycle was univoltine, and the relationships between the growth of Nemoura sichuanensis, physiological time, and effective accumulated water temperature were described using logistic regressions. The growth pattern was generally similar within year classes but growth rates did vary between year‐classes. Our field data suggest a critical thermal threshold for emergence in Nemoura sichuanensis, that was close to 9 °C. The total number of physiological days required for completing larval development was 250 days. The effective accumulated water temperature was 2500 degree‐days in the field. Development during the life cycle increased somewhat linearly with the physiological time and the effective accumulated water temperature, but some non‐linear relationships were best developed by logistic equations.

Core binding factor at the crossroads: Determining the fate of the HSC
Authors: Link Kevin A. , Chou Fu‐Sheng , Mulloy James C. 
Published: October 2009

AbstractHematopoietic development requires coordinated actions from a variety of transcription factors. The core binding factor (CBF), consisting of a Runx protein and the CBFβ protein, is a transcription factor complex that is essential for emergence of the hematopoietic stem cell (HSC) from an endothelial cell stage. The hematopoietic defects observed in either Runx1 or CBFβ knockout mice underscore the necessity of this complex for definitive hematopoiesis. Despite the requirement for CBF in establishing definitive hematopoiesis, Runx1 loss has minimal impact on maintaining the HSC state postnatally, while CBFβ may continue to be essential. Lineage commitment, on the other hand, is significantly affected upon CBF loss in the adult, indicating a primary role for this complex in modulating differentiation. Given the impact of normal CBF function in the hematopoietic system, the severe consequences of disrupting CBF activity, either through point mutations or generation of fusion genes, are obvious. The physiologic role of CBF in differentiation is subverted to an active process of self‐renewal maintenance by the genetic aberrations, through several possible mechanisms, contributing to the development of hematopoietic malignancies including myelodysplastic syndrome and leukemia. The major impact of CBF on the hematopoietic system in both development and disease highlights the need for understanding the intricate functions of this complex and reiterate the necessity of continued efforts to identify potential points of therapeutic intervention for CBF‐related diseases.

Published: October 2009

AbstractThe nutritional value of maize seed is limited due to its high content of storage proteins (zeins), which are deficient in essential amino acids such as lysine and tryptophan. In a previous paper, we showed that protein bodies obtained from BR473 maize variety, developed by Embrapa (Brazilian Agricultural Research Corporation), were mainly constituted by Z27 and a smaller quantity of Z50 γ‐zeins. Besides zein proteins, other not identified protein band in the SDS/PAGE was also observed, which could indicate the presence of non‐zein proteins additionally to γ‐zeins. In the present paper, we have demonstrated the presence of non‐zein proteins in BR473 maize protein bodies by LC‐nanoESI‐MS/MS and database searching. This fact could be related to the excellent energetic value and higher protein quality of BR473 maize grains, since high lysine concentration in some maize varieties has been related to the presence of cytoskeleton proteins that are non‐zeins. We have identified the following proteins: Brittle‐1 protein (chloroplast precursor), Legumin‐1, glyceroldehyde‐3‐phosphate dehydrogenase, and elongation factor 1‐α.
Study on the migration of bisphenol‐A from baby bottles by stir bar sorptive extraction‐thermal desorption‐capillary GC‐MS
Authors: De Coensel Nathalie , David Frank , Sandra Pat 
Published: October 2009

AbstractMigration of bisphenol‐A (BPA), the principal monomer of polycarbonate (PC) baby bottles, was investigated using an aqueous migration simulant. BPA was determined in 200 mL water samples using stir bar sorptive extraction (SBSE) after in situ derivatization with acetic acid anhydride followed by thermal desorption (TD)‐capillary GC‐MS. The concentration of BPA was calculated using the deuterated internal standard d6‐BPA. Calibration for BPA was shown to be linear in a concentration range from 1 ng/L to 10 μg/L with a correlation coefficient >0.99. The LOD for BPA (as acetate) was 0.12 ng/L and LOQ 0.40 ng/L (ppt). PC bottles were heated in a water bath and in a microwave oven at four different temperatures (37, 53, 65, and 85°C). The higher the temperature, the more the BPA was released, and after a few heating cycles, the released concentrations became constant. At normal use, i.e. at 37°C, concentrations are ca. 10 ng/L. No significant difference was noted between water bath and microwave heating illustrating that migration of BPA is mainly temperature dependent.
The relevance of epigenetics to PTSD: Implications for the DSM‐V
Authors: Yehuda Rachel , Bierer Linda M. 
Published: October 2009

AbstractEpigenetic modifications, such as DNA methylation, can occur in response to environmental influences to alter the functional expression of genes in an enduring and potentially, intergenerationally transmissible manner. As such, they may explain interindividual variation, as well as the long‐lasting effects of trauma exposure. Although there are currently no findings that suggest epigenetic modifications that are specific to posttraumatic stress disorder (PTSD) or PTSD risk, many recent observations are compatible with epigenetic explanations. These include recent findings of stress‐related gene expression, in utero contributions to infant biology, the association of PTSD risk with maternal PTSD, and the relevance of childhood adversity to the development of PTSD. The relevance of epigenetic mechanisms to formulations of PTSD for the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM‐V) is described.
Friction reduction in rolling bearing by using polymer additives
Authors: Bercea Maria , Bercea Mihai 
Published: October 2009

AbstractThe friction torque on the outer ring of a tapered roller bearing has been experimentally measured for a mineral oil (base oil), as well as for samples of the base oil additived with low‐density polyethylene. The data show an important reduction of friction by introducing the polymer into the base oil due to the film formed by the adsorption of macromolecular coils on the solid surface. The effectiveness of macromolecular additive contribution to friction behaviour is described in terms of polymer efficiency, which shows maximum values at low polymer concentrations.

The spacing effect in marketing: A review of extant findings and directions for future research
Authors: Noel Hayden , Vallen Beth 
Published: October 2009

AbstractThe spacing effect refers to the advantage in memory for information repeated at separate points in time over information repeated in massed fashion. This phenomenon has been extensively studied in psychology and has a wide scope of application. In spite of its possible applications, particularly related to advertising effectiveness, the spacing effect and its underlying theories have received limited attention in marketing. Evidence suggests that encoding variability theory, the one most frequently cited in marketing to explain the spacing effect, cannot explain existing empirical evidence as well as two other theories, reconstruction theory and study‐phase retrieval theory. This paper reviews these theories, as well as extant research, and discusses implications for advertising and directions for future research in marketing. © 2009 Wiley Periodicals, Inc.
Face as a mediator of the relationship between material value and brand consciousness
Authors: Liao Jiangqun , Wang Lei 
Published: October 2009

AbstractAlthough the relationship between materialism and name‐brand consumption has been documented in literature, its relational mechanism is not well addressed. It can hardly explain why people buy brand products without really knowing about the brands. In this case, people may consume brand products not for material possessions but for social needs, such as a desire to have favorable social self‐worth and to be respected in relation to others and social activities, which is defined as face (Ting‐Toomey & Kurogi, 1998). The present study explored how the relationship between materialism and brand consciousness is influenced by face. The role of face was tested both as a moderator and as a mediator. The results showed that face consciousness, material values, and brand consciousness were significantly correlated but did not exhibit significant interaction. Multiple regression analyses support face not as a moderator, but as a partial mediator. The results provide new insights into the mechanisms of how materialism and face influence brand consciousness differently. The theoretical meaning and implications for marketing management are discussed. © 2009 Wiley Periodicals, Inc.
Outcome of active disease in ankylosing spondylitis: A prospective study
Authors: Martindale J. , Smith J. , Grennan D. , Goodacre L. , Goodacre J.A. 
Published: October 2009

AbstractBackground: People with ankylosing spondylitis (AS) typically experience episodic exacerbations, but the extent to which they subsequently experience a sustained reduction in disease markers below recognized thresholds for active disease is unclear.Objective: To investigate changes in, and associations between, disease markers over 18 months in people with active AS.Methods: Within a cohort of 89 participants with AS, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores of 4 or higher were used to identify those with active disease. Standard assessment tools were used to monitor participants prospectively at four consecutive six‐monthly intervals. Participants received standard treatments but none received anti‐tumor necrosis factor‐alpha (TNFα) medication during the study.Results: The median age of the cohort was 50 years (inter‐quartile range [IQR] 38.5–55.5), the median age of disease onset was 25 years (IQR 18–33) and the median disease duration was 18 years (IQR 13–27). Forty‐seven (53%) participants had a BASDAI score of 4 or higher on the first assessment, of whom 45 (51%) scored 4 or higher on all subsequent assessments. Furthermore, 38 (43%) and 16 (18%) participants scored BASDAI 5 or 6, respectively, or higher, throughout. BASDAI scores correlated strongly with Bath Ankylosing Spondylitis Functional Index (BASFI) scores. Compared with 19 (21%) participants whose BASDAI scores were consistently below 4 throughout, participants with persistently high BASDAI scores showed higher scores for anxiety and depression, and some evidence of functional deterioration during the study period.Conclusions: In this cohort, disease markers in most people with active AS were sustained above the standard threshold for active disease. This has important implications for planning care pathways and for optimal utilization of anti‐TNFα treatment. Copyright © 2009 John Wiley & Sons, Ltd.
Frequency and predictors of nonalcoholic fatty liver disease in myotonic dystrophy
Authors: Shieh Kenneth , Gilchrist James M. , Promrat Kittichai 
Published: October 2009

AbstractNonalcoholic fatty liver disease (NAFLD) is a common chronic liver disease that is strongly associated with insulin resistance. Myotonic dystrophy (DM1) is the most common form of adult‐onset muscular dystrophy, and there is a high frequency of insulin resistance due to insulin receptor mRNA splicing defects in muscle tissue. The frequency and predictors of NAFLD in this population have not been described. Thirty‐six patients with DM1 were prospectively assessed for the presence of NAFLD and insulin resistance. NAFLD was defined by abnormal liver chemistry tests with ultrasound or pathologic evidence of steatosis in the absence of other liver disease. Abnormal liver chemistry tests were found in 44% of DM1 patients (mean ALT 73 ± 21 U/L, AST 53 ± 15 U/L), and 87% were attributable to NAFLD. Clinical predictors of NAFLD included increased insulin resistance by the homeostasis model assessment (HOMA) method (9.5 vs. 4.0 U,P= 0.03), elevated fasting insulin (40.4 vs. 16.1 μIU/ml,P= 0.03), abdominal obesity (98.6 vs. 90.8 cm,P= 0.03), elevated triglycerides (195.7 vs. 136.8 mg/dl,P= 0.02), and elevated total cholesterol (213.6 vs. 180.6 mg/dl,P= 0.02). NAFLD is very common and should be considered in the management of DM1. It is strongly associated with markers of insulin resistance and features of the metabolic syndrome. These findings support the role of peripheral insulin resistance in the pathogenesis of NAFLD. Muscle Nerve, 2010
A two‐echelon inventory‐location problem with service considerations
Authors: Mak Ho‐Yin , Shen Zuo‐Jun Max 
Published: October 2009

AbstractWe study the problem of designing a two‐echelon spare parts inventory system consisting of a central plant and a number of service centers each serving a set of customers with stochastic demand. Processing and storage capacities at both levels of facilities are limited. The manufacturing process is modeled as a queuing system at the plant. The goal is to optimize the base‐stock levels at both echelons, the location of service centers, and the allocation of customers to centers simultaneously, subject to service constraints. A mixed integer nonlinear programming model (MINLP) is formulated to minimize the total expected cost of the system. The problem is NP‐hard and a Lagrangian heuristic is proposed. We present computational results and discuss the trade‐off between cost and service. © 2009 Wiley Periodicals, Inc. Naval Research Logistics 2009
