Recent studies have shown that hyperinsulinemia may increase the cancer risk. Moreover, many tumors demonstrate an increased activation of IR signaling pathways. Phosphatidylinositol 3-kinase (PI3K) is necessary for insulin action. In epithelial cells, which do not express GLUT4 and gluconeogenic enzymes, insulin-mediated PI3K activation regulates cell survival, growth, and motility. Although the involvement of the regulatory subunit of PI3K (p85αPI3K) in insulin signal transduction has been extensively studied, the function of its N-terminus remains elusive. It has been identified as a serine (S83) in thep85αPI3Kthat is phosphorylated by protein kinase A (PKA). To determine the molecular mechanism linking PKA to insulin-mediated PI3K activation, we usedp85αPI3Kmutated forms to prevent phosphorylation (p85A) or to mimic the phosphorylated residue (p85D). We demonstrated that phosphorylation ofp85αPI3KS83 modulates the formation of thep85αPI3K/IRS-1complex and its subcellular localization influencing the kinetics of the insulin signaling both on MAPK-ERK and AKT pathways. Furthermore, thep85αPI3KS83 phosphorylation plays a central role in the control of insulin-mediated cell proliferation, cell migration, and adhesion. This study highlights thep85αPI3KS83 role as a key regulator of cell proliferation and motility induced by insulin in MCF-7 cells breast cancer model.

Published: July 2014

Hemoperitoneum during pregnancy is a rare but potentially lethal clinical condition. Improvements in antenatal and intrapartum care, especially in surgical and anesthetic techniques, have reduced maternal mortality; perinatal mortality remains very high (31%). Treatment is based on the systemic correction of hypovolemia and immediate surgery via laparotomy or laparoscopy in cases in the first trimester of pregnancy for hemostatic purposes. Sometimes, hysterectomy is needed. A 35-year-old Asiatic primigravid woman at 37 weeks’ gestation with otherwise uneventful pregnancy came to the hospital referring abrupt-onset lumbar and abdominal pain. A bleeding uterine superficial varicocele of about 7 cm was found on the left uterine horn during Caesarean section. Interventional radiologic embolization of both uterine arteries was successfully performed. Posterior evolution of the patient was favorable. Percutaneous vascular embolization of the uterine arteries is an effective alternative treatment for many obstetrical and gynecological causes of bleeding. The main advantage of this technique is the low rate of serious complications and the preservation of reproductive function. To our knowledge, this is the first case of spontaneous intrapartum hemoperitoneum treated with this technique. An early diagnosis and a rapid indication of this therapeutic option are essential. Hemodynamic stability is needed to decide this conservative management.
Effects of InactivatedBordetella pertussison Phosphodiesterase in the Lung of Ovalbumin Sensitized and Challenged Rats
Authors: Wang Ya-Juan , Song Shun-De , Chen Jun-Chun , Wang Xue-Feng , Jiang Ya-Li , Xie Qiang-Min , Chen Ji-Qiang , Li Zi-Gang , Tang Hui-Fang
Published: July 2014

This paper indicated that inactivatedBordetella pertussis(iBp) can enhance the lung airway hyperreactivity of the rats sensitized and challenged with OVA. The mechanisms were involved in the upregulation of cAMP-PDE activity and PDE4A, PDE4D, and PDE3 gene expression in the lungs. But only PDE4 activity was different between the OVA and OVA+iBp groups, and PDE4D expression was significantly increased in iBp rats alone. So, our data suggested that cosensitization with OVA and iBp affects lung airway reactivity by modulating the lung cAMP-PDE activity and PDE4D gene expression.

Published: July 2014

Aging increases the risk for cardiovascular morbidity and mortality. Chronic low-grade inflammation deteriorates vascular function, increases age-related vascular stiffness, and affects hemodynamics. The proinflammatory cytokine macrophage migration inhibitory factor (MIF) is a major mediator of atherosclerosis. Plasma MIF levels are associated with arterial stiffness, a hallmark of vascular aging. Preclinical studies show that blockade of MIF leads to atherosclerotic plaque regression. Nutritional approaches provide opportunities to counteract age-related inflammation. Following a chronic dietary supplementation with the micronutrient nitrate has been demonstrated to improve vascular stiffness. Whether dietary nitrate affects circulating MIF levels is not known. In a randomized placebo-controlled, double-blinded study, elderly subjects received a dietary nitrate supplementation for 4 weeks. Dietary nitrate led to a decrease in plasma MIF levels in the elderly and to an improvement in vascular functions. This was associated with a reduction in central systolic blood pressure. Our data show that supplementation with dietary nitrate is associated with a reduction of circulating MIF levels along with an improvement in vascular function. This supports the concept of dietary approaches to modulate age-related changes of vascular functions.
Robust Nonlinear Control with Compensation Operator for a Peltier System
Authors: Wen Sheng-Jun , Wang Dong-Yun , Zhang Lei , Deng Ming-Cong
Published: July 2014

Robust nonlinear control with compensation operator is presented for a Peltier actuated system, where the compensation operator is designed by using a predictive model on heat radiation. For the Peltier system, the heat radiation is related to the fourth power of temperature. So, the heat radiation is affected evidently by the temperature when it is high and temperature difference between the system and environment is large. A new nonlinear model with the heat radiation is set up for the system according to some thermal conduction laws. To ensure robust stability of the nonlinear system, operator based robust right coprime factorization design is considered. Also, a compensation operator based on a predictive model is proposed to cancel effect of the heat radiation, where the predictive model is set up by using radial basis kernel function based SVM (support vector machine) method. Finally, simulation results are given to show the effectiveness of the proposed scheme.
On Monotonic and Nonnegative Solutions of a Nonlinear Volterra-Stieltjes Integral Equation
Authors: Zając Tomasz
Published: July 2014

We study the existence of monotonic and nonnegative solutions of a nonlinear quadratic Volterra-Stieltjes integral equation in the space of real functions being continuous on a bounded interval. The main tools used in our considerations are the technique of measures of noncompactness in connection with the theory of functions of bounded variation and the theory of Riemann-Stieltjes integral. The obtained results can be easily applied to the class of fractional integral equations and Volterra-Chandrasekhar integral equations, among others.

Published: July 2014

The main objective of this paper is to build a simple mathematical competent model that describes the circuits and interconnections of a 3-phase squirrel cage induction motor used for industrial applications. This paper presents the detailed analysis of theoretical concepts used in mathematical modeling, simulation’ and hardware implementation. The objective of this work is to compare the dynamic performances of the vector control methods for CSI fed IM drives. Based on the results, dynamic performances of the proposed drives are individually analysed using the sensitivity tests. The tests that are chosen for the comparison are step changes in the reference speed and torque of the motor drive. Here the IM is mathematically modeled in different reference frames for input output linearization (IOL) control, field oriented control (FOC), and direct torque control method (DTC) which are designed using hardware equivalent mathematical equations. The most important contributions in this paper are mathematical simulation structure of IM model in rotor flux frame using current and speed that were developed and implemented in MATLAB-Simulink. The operation and performance of the different vector control methods are verified by simulation using MATLAB/SIMULINK and experimental results.

Published: July 2014

A comparative study of the effect of magnesium oxide and calcium carbonate as support material in the synthesis of carbon nanotubes using the catalyst Fe/Co is presented. The synthesized carbon nanotubes were characterized with Raman spectroscopy, scanning electron spectroscopy (SEM), high-resolution transmission electron microscopy (HRTEM), X-ray diffraction spectroscopy (XRD), and energy dispersive spectroscopy (EDS). The morphology of the carbon nanotubes synthesized with magnesium oxide as support material gives rise to carbon nanotubes with consistent and well-defined structure unlike that synthesized with calcium carbonate. TheID/IGratio of synthesized carbon nanotubes (CNTs) was 0.8544 for magnesium oxide supported compared to 0.8501 for calcium carbonate supported carbon nanotube.
A New Business Mode for FTs Chain in an E‐Commerce Environment
Authors: Wang Xihui , Wu Yonggang , Liang Liang
Published: July 2014

With the rise in the online demand for fashion and textiles (FTs) along with the development of e‐commerce, a business mode called drop‐shipping mode has emerged. Despite the fact that the drop‐shipping mode has many merits, this method has less earning power compared with the traditional business mode. This study proposes a mix business mode for FTs chains in an e‐commerce environment. Traditional and drop‐shipping modes are special cases of the mix mode. In addition, a generalized model is built to analyze the profitability of FTs chains. Our study shows that, in most cases, the mix mode improves overall profit of FTs chain. Moreover, we consider the seasonality and the short life cycle of fashion items in analyzing the relationship between the e‐retailer′s optimal inventory level and demand distribution parameters. The numerical example shows that, by changing their inventory level, e‐retailers can address the demand fluctuation using the mix mode. The proposed mix mode employs both business modes to enhance the profitability of a FTs chain. As such, the mix mode is an effective method to address demand fluctuation for FTs in an e‐commerce environment.
The Weight Distributions of a Class of Cyclic Codes with Three Nonzeros over𝔽3
Authors: Liu Xiaogang , Luo Yuan
Published: July 2014

Cyclic codes have efficient encoding and decoding algorithms. The decoding error probability and the undetected error probability are usually bounded by or given from the weight distributions of the codes. Most researches are about the determination of the weight distributions of cyclic codes with few nonzeros, by using quadratic forms and exponential sums but limited to low moments. In this paper, we focus on the application of higher moments of the exponential sums to determine the weight distributions of a class of ternary cyclic codes with three nonzeros, combining with not only quadratic forms but also MacWilliams’ identities. Another application of this paper is to emphasize the computer algebra system Magma for the investigation of the higher moments. In the end, the result is verified by one example using Matlab.
Efficient and Scalable Graph Similarity Joins in MapReduce
Authors: Chen Yifan , Zhao Xiang , Xiao Chuan , Zhang Weiming , Tang Jiuyang
Published: July 2014

Along with the emergence of massive graph-modeled data, it is of great importance to investigate graph similarity joins due to their wide applications for multiple purposes, including data cleaning, and near duplicate detection. This paper considers graph similarity joins with edit distance constraints, which return pairs of graphs such that their edit distances are no larger than a given threshold. Leveraging the MapReduce programming model, we proposeMGSJoin, a scalable algorithm following the filtering-verification framework for efficient graph similarity joins. It relies on counting overlapping graph signatures for filtering out nonpromising candidates. With the potential issue of too many key-value pairs in the filtering phase, spectral Bloom filters are introduced to reduce the number of key-value pairs. Furthermore, we integrate the multiway join strategy to boost the verification, where a MapReduce-based method is proposed for GED calculation. The superior efficiency and scalability of the proposed algorithms are demonstrated by extensive experimental results.

Published: July 2014

Putrajaya is a new federal administrative capital of Malaysia which has been set to achieve a 70% share of all travels by public transport in the city area. However, the current modal split between the public transport and private transport is 15 : 85. In order to understand travelers’ willingness to use the public transport, a conceptual model has been developed to determine the factors that affect them to use the public transport instead of travelling in their own cars. Various variables such as service quality, environmental impact, attitude, and behavior intention were analyzed and tested using structural equation model (SEM). Results indicate that the service quality and attitude are found to have positive effects on the behavioral intention of taking the public transport. Other than this, this study also shows that the service quality and environmental impact have some positive influences on the attitude to using the public transport. However, environmental impact has no significant, positive, and direct effect on behavioral intention. The results of this study demonstrate that the model that was developed is useful in predicting the public transport and it could provide a more complete understanding of behavioral intention towards public transport use.
Wolff-Parkinson-White Syndrome Mimics a Conduction Disease
Authors: Marrakchi S. , Kammoun I. , Kachboura S.
Published: July 2014

Background. It is important to recognise Wolff-Parkinson-White (WPW) syndrome in electrocardiograms (ECG), as it may mimic ischaemic heart disease, ventricular hypertrophy, and bundle branch block. Recognising WPW syndrome allows for risk stratification, the identification of associated conditions, and the institution of appropriate management.Objective. The present case showed that electrophysiological study is indicated in patients with abnormal ECG and syncope.Case Report. A 40-year-old man with Wolff-Parkinson-White syndrome was presented to emergency with syncope. A baseline ECG was a complete right branch block and posterior left hemiblock. He was admitted to the cardiac care unit for pacemaker implantation. The atypical figure of complete right branch block and posterior left hemiblock was thought to be a “false positive” of conduction abnormality. But the long anterograde refractory period of the both accessory pathway and atrioventricular conduction may cause difficulty in diagnosing Wolff-Parkinson-White syndrome,Conclusion. A Wolff-Parkinson-White Syndrome may mimic a conduction disease. No reliable algorithm exists for making an ECG diagnosis of a preexcitation syndrome with conduction disorders. This can lead to diagnostic and therapeutic dilemmas in the context of syncope.
Identification of Stochastic Timed Discrete Event Systems with st‐IPN
Authors: Muñoz Doyra Mariela , Correcher Antonio , García Emilio , Morant Francisco
Published: July 2014

This paper presents a method for the identification of stochastic timed discrete event systems, based on the analysis of the behavior of the input and output signals, arranged in a timeline. To achieve this goal stochastic timed interpreted Petri nets are defined. These nets link timed discrete event systems modelling with stochastic time modelling. The procedure starts with the observation of the input/output signals; these signals are converted into events, so that the sequence of events is the observed language. This language arrives to an identifier that builds a stochastic timed interpreted Petri net which generates the same language. The identified model is a deterministic generator of the observed language. The identification method also includes an algorithm that determines when the identification process is over.

Published: July 2014

Host genetic susceptibility is an important risk factor in infectious diseases. We explored the distribution of Q223R mutation in leptin receptor gene of amoebic liver abscess (ALA) patients of North India. A total of 55 ALA samples along with 102 controls were subjected to PCR-RFLP analysis. The frequency of allele “G” (coding for arginine) was in general high in Indian population irrespective of the disease. Our results of Fisher exact test shows that heterozygous mutant (QQ versus QR,P=0.049) and homozygous mutant (QQ versus RR,P=0.004) were significantly associated with amoebic liver abscess when compared with homozygous wild (QQ).
Implant Maintenance: A Clinical Update
Authors: Gulati Minkle , Govila Vivek , Anand Vishal , Anand Bhargavi
Published: July 2014

Introduction. The differences in the supporting structure of the implant make them more susceptible to inflammation and bone loss when plaque accumulates as compared to the teeth. Therefore, a comprehensive maintenance protocol should be followed to ensure the longevity of the implant. Material and Method. A research to provide scientific evidence supporting the feasibility of various implant care methods was carried out using various online resources to retrieve relevant studies published since 1985. Results. The electronic search yielded 708 titles, out of which a total of 42 articles were considered appropriate and finally included for the preparation of this review article. Discussion. A typical maintenance visit for patients with dental implants should last 1 hour and should be scheduled every 3 months to evaluate any changes in their oral and general history. It is essential to have a proper instrument selection to prevent damage to the implant surface and trauma to the peri-implant tissues. Conclusion. As the number of patients opting for dental implants is increasing, it becomes increasingly essential to know the differences between natural teeth and implant care and accept the challenges of maintaining these restorations.

Background.To evaluate the outcomes of nasopharyngeal carcinoma (NPC) patients treated with helical tomotherapy (HT).Methods.Between September 2007 and August 2012, 190 newly diagnosed NPC patients were treated with HT. Thirty-one patients were treated with radiation therapy as single modality, 129 with additional cisplatin-based chemotherapy with or without anti-EGFR monoclonal antibody therapy, and 30 with concurrent anti-EGFR monoclonal antibody therapy.Results.Acute radiation related side effects were mainly grade 1 or 2. Grade 3 and greater toxicities were rarely noted. The median followup was 32 (3–38) months. The local relapse-free survival (LRFS), nodal relapse-free survival (NRFS), distant metastasis-free survival (DMFS), and overall survival (OS) were 96.1%, 98.2%, 92.0%, and 86.3%, respectively, at 3 years. Cox multivariate regression analysis showed that age and T stage were independent predictors for 3-year OS.Conclusions.Helical tomotherapy for NPC patients achieved excellent 3-year locoregional control, distant metastasis-free survival, and overall survival, with relatively minor acute and late toxicities. Age and T stage were the main prognosis factors.
Racial Threat Theory: Assessing the Evidence, Requesting Redesign
Authors: Dollar Cindy Brooks
Published: July 2014

Racial threat theory was developed as a way to explain how population composition influences discriminatory social control practices and has become one of the most acknowledged frameworks for explaining racial disparity in criminal justice outcomes. This paper provides a thorough review of racial threat theory and empirical assessments of the theory and demonstrates that while scholars often cite inconsistent support for the theory, empirical discrepancies may be due to insufficient attention to the conceptual complexity of racial threat. I organize and present the following review around 4 forms of state-sanctioned control mechanisms: police expenditures, arrests, sentencing, and capital punishment. Arguing that the pervasiveness of racialization in state controls warrants continued inquiry, I provide suggestions for future scholarship that will help us develop enhanced understanding of how racial threat may be operating.
Effect of Reduction of the Pulse Rates of Fluoroscopy and CINE-Acquisition on X-Ray Dose and Angiographic Image Quality During Invasive Cardiovascular Procedures
Authors: Pyne Christopher T. , Gadey Gautam , Jeon Cathy , Piemonte Thomas , Waxman Sergio , Resnic Frederic
Published: July 2014

Background—

Reducing digital pulse rates (PR) are known to reduce total energy during invasive cardiovascular procedures, which likely has benefits for patients and staff. Physicians may be reluctant to reduce these parameters because they fear a decline in image quality that could affect procedural outcomes. We sought to assess the effect of default rates of fluoroscopy (Fluoro) and CINE-acquisition (CINE) on total x-ray dose and image quality during invasive cardiovascular procedures.

Methods and Results—

We retrospectively reviewed procedures done with 2 default PRs: a standard dose cohort (PR, 15 for Fluoro and CINE), and a reduced dose cohort (PR, 10 for Fluoro and CINE). Total x-ray dose, Fluoro time, and contrast use were compared between groups. A blinded angiographic image quality assessment was then performed using an objective 10-point angiographic quality score. There were no significant differences between cohorts for fluoroscopy time or contrast use. The reduced dose cohort has a significant reduction in mean total x-ray dose (PR 15, 1763.1 mGy; PR 10, 1179.1 mGy;
P
<0.0001). When adjusted for potential confounders, a 38% reduction in total x-ray dose was identified (
P
<0.0001). There was no difference in adjusted angiographic quality score between the cohorts (PR 15, 7.90; PR 10, 8.00;
P
=0.67), indicating no decline in image quality with PR reduction.

Conclusions—

Reducing default PRs during invasive cardiovascular procedures yields large and significant reductions in total x-ray energy with no decline in angiographic image quality.
Institutional Interplay between the Chiang Mai Initiative and the International Monetary Fund
Authors: Loewen Howard
Published: July 2014

This paper argues that the emergence and implementation of an international institution can only be fully understood if it is seen as part of a larger regime complex. It analyses the establishment of the Chiang Mai Initiative (CMI), a regional financial arrangement in East Asia, by focusing on its interplay with the International Monetary Fund (IMF). It will be argued that four factors play a major role in the CMI’s interactions within the financial regime complex: the lack of a clean slate, forum shopping, legal inconsistencies and the politics of implementation.
Youth and the Making of Modern China
Authors: Graziani Sofia
Published: July 2014

The beginning of the twentieth century marked in China the emergence of “youth” (qingnian) as a distinct analytical category associated with national modernity. As the term qingnian assumed unprecedented significance, a new generation of educated youth aware of its role as agent of social change also came into being. In fact, the May Fourth movement turned Chinese youth into a social force that could be organized and mobilized for effective action by nascent ideologically committed political parties. The historical analysis of the Socialist/Communist Youth League, the Chinese Communist Party-affiliated youth organization, is rather biased, as official historiography tends to overemphasize its role as well as the symbiotic nature of its relationship with the Party. Moreover, so far Western scholars have carried out little work on the topic. This paper makes use of largely unexploited documentary material to reconstruct the history of the Youth League from its inception to its disbandment on the eve of the Sino-Japanese war, and to show how the League interacted with the party’s development in the early stage of the Communist movement. It argues that, in a political context of contestation over power, it was mainly conceived as a tool for Communist propaganda and mobilization of mass support. Yet, the League’s relationship with the party was not always one of symbiosis and subordination.
Risshō Kōseikai within Globalization
Authors: Dessì Ugo
Published: July 2014

Based on several streams of globalization theory and the author’s previous work, this article proposes a multidimensional approach to the study of Risshō Kōseikai under globalization. The analysis shows that this Buddhism-based new religious movement is involved in global dynamics in various guises. Not only does Risshō Kōseikai contribute to global culture through its presence on the Internet, international cooperation, and other activities, but it also acts as a glocalizer by creating new religious hybrid forms at the local level, as is evident in the recent institutional interest in the environmental crisis. There are also indications that these processes, which per se denote a positive engagement with globalization, may be entangled with the defense of particularism. Reactions to the increasing global availability of religious communication and the relativization of religious values are also explored, which indicate the official endorsement of pluralism and an underlying tendency toward inclusivism. At the systemic level, Risshō Kōseikai (as part of the global religious subsystem) is shown to be engaged in border negotiations with dominant global subsystems such as politics and science, and in addressing residual problems left unsolved by these subsystems in an attempt to find legitimation for religion in global society.
The Glocalization Process of Shin Buddhism in Brasilia
Authors: Matsue Regina Yoshie
Published: July 2014

The glocalization process of Shin Buddhism in Brasilia is the focus of this article. The first part of this work presents a historical and sociological overview of the introduction and settlement of Shin Buddhism in Brazil, and the second part examines the specificities of the contemporary temple situation in Brasilia. This paper illustrates how external cultural inflows interact and negotiate with daily local actions and demand and thus acquire a distinctive connotation at the local level. However, due to the mixture of local cultural elements in interaction with imported ones the processes of appropriation and transformation may allow the emergence of something new and unique. In the glocalization of Shin Buddhist practices in Brasilia the work of innovation and articulation conducted by some members of the clergy has been fundamentally important. Especially, the clergy have understood the demand for self-cultivation practices coming from a larger audience and incorporated meditation in the temple space.

Published: July 2014

An Arthrobotrys species with adhesive nets (trapping device) was isolated from hot-spring waterlogged soil during research on evolutionary patterns of nematode-trapping fungi in Yunnan Province, China. Morphological and phylogenetic analyses indicate this is a novel predatory species of Arthrobotrys, which we herein introduce as A. xiangyunensis. The new species is characterized by occasionally branched conidiophores, colorless, fusiform to oval or clavate conidia which mostly have 1–5 septa and measure 27–72(55.8) × 14.5–28.5(21.9) μm. The new species is introduced with illustrations in this paper. Its morphology is rather similar to Monacrosporium guizhouense, M. longiphorum, M. sphaeroides, M. eudermatum and Arthrobotrys mangrovispora, but the phylogenetic analysis shows that A. xiangyunensis and its morphological relatives are distinct.

New combinations in Balkans Clinopodium (Lamiaceae)
Authors: Iamonico Duilio , BOGDANOVIĆ SANDRO
Published: July 2014

To accommodate the morphological diversity of Satureja s.l. (Lamiaceae, Nepetoideae, Menthae, Menthinae), many taxonomists (Bentham 1848, Boissier 1879, Ball & Getliffe 1972, Davis 1982) assign the species of this genus to different genera, mainly Satureja Linnaeus (1753: 587), Clinopodium Linnaeus (1753: 587), Acinos Miller (1754: without pagination), Calamintha Miller (1754: without pagination), and Micromeria Bentham (1829: ad tab 1282, no. 17), while others recognize only Satureja (e.g., Greuter et al. 1984) or Clinopodium (e.g., Kuntze 1891). Recent molecular studies (Wagstaff & al. 1995, Prether & al. 2002, Harley & al. 2004, Trusty & al. 2004, Bräuchler & al. 2005) have contributed to a better understanding of the group and they favoured abandonment of the concept of Satureja sensu lato. As consequence, the genera Acinos, Calamintha and Micromeria p.p. were transferred to the genus Clinopodium and several new combinations were validated both for the Americas (Cantino & Wagstaff 1998, Govaerts 1999, Harley & Paucar 2000, Pool 2008) and for Europe (Rosselló 2006, Bräuchler & al. 2008a, 2008b, Peruzzi & Conti 2008, Brullo & Brullo 2009, Bartolucci & Conti, 2011, 2012).

Based on re-examination of material belonging to the Museum of Zoology, Hamburg University, Germany, especially Georg Ulmer’s collection, as well as newly collected specimens from the Sunda Islands, the genuine concept of Compsoneuria Eaton, 1881 is revised. The genus has had as junior synonyms Compsoneuriella Ulmer, 1939 (Oriental) and Notonurus Crass, 1947 (Afrotropical). A recent molecular study removed Notonurus from this synonymy. The type species of Compsoneuria, Compsoneuria spectabilis Eaton, 1881, is redescribed. A lectotype male imago is designated for Compsoneuriella thienemanni Ulmer, 1939, type species of Compsoneuriella. Based on egg morphology, nymphal stages of both Compsoneuria and Compsoneuriella are unequivocally attributed. The nymph of Compsoneuria spectabilis is described and corresponds in part to what Ulmer (1939) described as the nymph of Compsoneuriella thienemanni. The latter nymph is also redescribed from material collected recently in Sumatra. Due to the important number of morphological differences between these two species, Compsoneuriella stat. prop. is removed from its synonymy with Compsoneuria. Besides C. thienemanni, the genus Compsoneuriella encompasses C. langensis (Braasch & Boonsoong, 2010) comb. nov. from Thailand and C. tagbanua (Braasch & Freitag, 2008) comb. nov. from the Philippines (Palawan), which is partially redescribed. All other species under the combined concept of Compsoneuria/Compsoneuriella are mentioned and their generic placements are discussed. The new combination Afronurus taipokauensis (Tong & Dudgeon, 2003) comb. nov. from Hong Kong, China is proposed.

We describe a new species of the gekkonid genus Cyrtodactylus on the basis of two specimens collected from limestone forests of Luang Prabang Province, northern Laos. Morphologically, the new species is distinguishable from its congeners by a combination of the following diagnostic characters: maximum SVL 86.1 mm; supralabials 9 or 10; infralabials 7–9; dorsal tubercles in 15 or 16 rows at midbody; ventral scale rows 34–36 at midbody; precloacal groove absent; femoral scales not distinctly enlarged; precloacal pores absent in females (unknown in males); subdigital lamellae under the fourth finger 18 or 19, under the fourth toe 18–20; subcaudals not transversally enlarged; dorsal bands white, 4 or 5 between limb insertions plus another one between hind limbs; tail banded. Based on molecular analyses, the new species is clustered in the same clade with C. wayakonei and two other species from Luang Prabang and Houaphan provinces.

Observations and sea surface temperature (SST)-forced ECHAM5 simulations are examined to study the seasonal cycle of eastern Africa rainfall and its SST sensitivity during 1979–2012, focusing on interannual variability and trends. The eastern Horn is drier than the rest of equatorial Africa, with two distinct wet seasons, and whereas the October–December wet season has become wetter, the March–May season has become drier.

The climatological rainfall in simulations driven by observed SSTs captures this bimodal regime. The simulated trends also qualitatively reproduce the opposite-sign changes in the two rainy seasons, suggesting that SST forcing has played an important role in the observed changes. The consistency between the sign of 1979–2012 trends and interannual SST–precipitation correlations is exploited to identify the most likely locations of SST forcing of precipitation trends in the model, and conceivably also in nature. Results indicate that the observed March–May drying since 1979 is due to sensitivity to an increased zonal gradient in SST between Indonesia and the central Pacific. In contrast, the October–December precipitation increase is mostly due to western Indian Ocean warming.

The recent upward trend in the October–December wet season is rather weak, however, and its statistical significance is compromised by strong year-to-year fluctuations. October–December eastern Horn rain variability is strongly associated with El Niño–Southern Oscillation and Indian Ocean dipole phenomena on interannual scales, in both model and observations. The interannual October–December correlation between the ensemble-average and observed Horn rainfall 0.87. By comparison, interannual March–May Horn precipitation is only weakly constrained by SST anomalies.
South Asian Ethnicity and Cardiovascular Risk

South Asians (SAs), in their countries or after migration, are at high risk of coronary artery disease (CAD) and mortality compared to other ethnic groups. It has been shown that >90% of CAD global risk could be attributed to 9 modifiable risk factors (RFs) worldwide. However, these conventional RFs may not fully explain this high risk of CAD among SAs. Therefore, attention has been directed toward nonconventional RFs. In this narrative review, we evaluate the conventional and emerging cardiovascular RFs characterizing SAs. These factors may explain the high morbidity and mortality among SAs. Further prospective studies are urgently needed to set algorithms for the optimal management of these RFs in high-risk populations like SAs.

We report the relations between comorbidities and chronic venous disease. In this cross-sectional study, information was gathered from 1679 Serbian patients. The majority (65.0%) of patients were women. Mild forms of chronic venous disease (clinical, etiologic, anatomic and pathophysiologic [CEAP] classification; C0s-C1) were more frequent in women (11.6%), while severe forms (CEAP C4-C6) were more commonly encountered in men (42.1%). The most frequent comorbidity was emphysema/chronic obstructive pulmonary disease in both groups (74.3% in males and 70.6% in females). For females, diabetes mellitus ( P < .005), arterial hypertension ( P < .000), and skeletal/joint diseases ( P < .042) were more commonly found in the C4 to C6 category. Both males and females, with severe form of chronic venous disease, may benefit from additional screening for comorbidities. Further studies are needed to clarify the nature of association among comorbidities and chronic venous disease.

We hypothesized that contrast media volume–estimated glomerular filtration rate (CV–e-GFR) ratio may be a predictor of contrast media-induced acute kidney injury (CI-AKI). We investigated the associations between CV–e-GFR ratio and CI-AKI in 597 patients undergoing primary percutaneous coronary intervention (pPCI). An absolute ≥0.3 mg/dL increase in serum creatinine compared with baseline levels within 48 hours after the procedure was considered as CI-AKI; 78 (13.1%) of the 597 patients experienced CI-AKI. The amount of contrast during procedure was higher in the CI-AKI group than in those without CI-AKI (153 vs 135 mL, P = .003). The CV–e-GFR ratio was significantly higher in patients with CI-AKI than without (2.3 vs 1.5, P < .001). In multivariate analysis, independent predictors of CI-AKI were low left ventricular ejection fraction ( P = .018, odds ratio [OR] = 0.966), e-GFR <60 mL/min ( P = .012, OR = 2.558), and CV–e-GFR >2 ( P < .001, OR = 5.917). In conclusion, CV–e-GFR ratio is significantly associated with CI-AKI after pPCI.
Biological variation of cardiac troponin T in patients with end-stage renal disease and in healthy individuals
Authors: Corte Zoraida , García Camino , Venta Rafael
Published: July 2014

Background

Serum cardiac troponin T concentrations are important predictors of cardiovascular and all-cause mortality in end-stage renal disease. In patients with end-stage renal disease, assessment of serial results is essential to distinguish between a cardiovascular event and chronic elevation. We employed a high-sensitivity serum cardiac troponin T assay to evaluate the long-term biological variation in end-stage renal disease patients and in healthy individuals; these biological variation data were used to define the reference change value and the analytical goals.

Methods

Serum samples were collected from 18 end-stage renal disease patients in steady-state conditions, one per month for 6 months, and from 11 healthy volunteers at weekly intervals over 5 weeks. Biological variation data were derived using analysis of variance.

Results

Baseline serum cardiac troponin T concentrations in end-stage renal disease patients were above the 99th percentile of the healthy population and increased with duration of haemodialysis. For end-stage renal disease patients, within-subject (CVI) and between-subject (CVG) coefficients of variation were 14.7 and 77.8%, respectively, whereas these were 5.9 and 30.4%, respectively, for healthy individuals. The derived two-tailed and one-tailed reference change values were 44.1 and 37.1%, respectively, for end-stage renal disease patients, and 21.6 and 18.2% for healthy subjects.

Conclusions

For appropriate clinical management of end-stage renal disease patients in the context of a cardiovascular event, regular monitoring of serum cardiac troponin T concentrations could be important in order to allow future comparison through reference change value. Biological variation data in end-stage renal disease patients were significantly higher than for healthy individuals; therefore, the use of proper reference change value data is recommended. Moreover, the observed CVI values provide demanding imprecision goals for current technology.
Serum and synovial fluid chemokine ligand 2/monocyte chemoattractant protein 1 concentrations correlates with symptomatic severity in patients with knee osteoarthritis
Authors: Li Liang , Jiang Bao-En
Published: July 2014

Objective

Serum and synovial fluid (SF) chemokine ligand 2 (CCL2)/monocyte chemoattractant protein 1 (MCP-1) concentrations have been identified to be increased in osteoarthritis (OA) patients. The scope of this study was to examine CCL2 concentrations in serum and SF of knee OA patients and to explore their association with patient-reported symptomatic severity.

Method

One hundred and sixty-one knee OA patients and 138 healthy controls were enrolled into the study from our hospital. We collected Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores from OA patients and measured CCL2 concentrations in serum and SF using enzyme-linked immunosorbent assay method, and correlation between WOMAC scores and CCL2 concentrations were analysed.

Results

CCL2 concentrations in SF instead of serum were independently and positively associated with self-reported greater pain ( r = 0.460, P < 0.001) and physical disability ( r = 0.561, P < 0.001) in OA patients.

Conclusion

CCL2 in SF might serve as a novel and reliable biomarker for assessing symptomatic severity of OA.

Health care transition (HCT) from pediatric to adult-focused systems is a key milestone for youth. Developing self-care skills and HCT planning are key elements. In a survey at 4 pediatric specialty clinics to 79 youth aged 16 to 25 years and 52 parents, skill-based HCT readiness was assessed using the Transition Readiness Assessment Questionnaire (TRAQ). Multivariable logistic regression evaluated the association between TRAQ scores and self-care beliefs. In all, 70% of youth and 67% of parents believed that they/their child could manage their care. Only 38% of youth and 53% of parents reported thinking about HCT; only 18% of youth and 27% of parents reported having a HCT plan. Youth with higher TRAQ scores were more likely to believe they could manage their care, controlling for age and gender (adjusted odds ratio = 4.0, 95% confidence interval = 1.7-9.5). Transition readiness skills are associated with self-care beliefs. However, a mismatch exists between high reported self-care beliefs and low levels of transition planning.
