Syphilis and Its Correlates among Heterosexual Males Attending Sexually Transmitted Infection Clinics – Observation from a Multicity Cohort in Jiangsu Province, China

Objectives To estimate the prevalence of HIV and syphilis, incidence of syphilis and to identify the correlates of syphilis infection among heterosexual male attendees of sexually transmitted infection (STI) clinics (MSC). Methods A cohort study of one-year duration was conducted in Yangzhou and Changzhou cities in Jiangsu province of China. The baseline survey commenced in June 2009, recruited 1225 consenting adult MSCs (609 in Yangzhou and 617 in Changzhou) through STI-clinic based convenience sampling. Results Baseline HIV and syphilis prevalence were 0.49% and 17.29% respectively. Syphilis incidence rate was 7.22 per 100 person-years (6.53 in Yangzhou and 7.76 in Changzhou) during the 6-month follow-up with retention fractions of 27.38% and 35.15% for Yangzhou and Changzhou respectively. Majority of the participants were middle-aged, high school educated, married, living with partners and non-migrants. Very few subjects reported recent and consistent condom-use with regular partners. Although considerable number of MSCs reported recent sexual exposure with female sex workers (FSW) and non-FSW casual partners, the proportion of reported condom use was very low during those exposures. In multivariate analyses higher age, having recent sex with FSWs and being HIV-positive were associated with higher syphilis sero-positivity while higher education was protective. In bivariate analyses, being married, divorced/widowed, official residency of the study cities and non-use of condom with regular partners predicted higher risk. Conclusions Considering the potential bridging role of MSCs between high and low-risk populations, effective intervention strategies among them targeting the correlates of syphilis infection are urgently called for in Jiangsu province of China.
Proof of Caldararu's conjecture. An appendix to a paper by Yoshioka

We show that any orientation preserving Hodge isometry between the Hodge structures of two K3 surfaces X and X' twisted by Brauer classes $\alpha$ resp. $\alpha'$ can be lifted to a Fourier-Mukai equivalence between the derived categories of $\alpha$ resp. $\alpha'$-twisted sheaves.
Measurement based Analysis and Modelling of UMTS DCH Error Characteristics for Static Scenarios

(cid:151)For the evaluation of higher layer protocols, the simulation of cross-layer optimisation methods or the development of new algorithms for multimedia signal processing it is essential to know the exact error characteristics of the underlying channels. In this paper we show the analysis of the error characteristics of the UMTS DL (Down Link) DCH (Dedicated Channel) with 384kbit/s especially for static scenarios. The analysis is based on measurements in live UMTS networks in Vienna, Austria and the results are compared to the obtained statistics of measurements in a reference network where the transmission of data was performed without interference from other cells, multipath propagation or fading effects. Following the obtained statistics we develop a two-state model which is capable of describing the measured statistics properly. Furthermore, we analyse the correlation properties of the channel and we show a two-layer model for an improved representation of the statistical dependencies between the errors of the UMTS DL DCH.
Brief report: birth status, medical complications, and social environment: individual differences in development of preterm, very low birth weight infants.

OBJECTIVE To assess whether medical complications mediate the relationship between birth status (i.e., birth weight and gestational age) and developmental outcome of preterm, very low birth weight (VLBW) infants, as well as the role of the early social environment (maternal distress and social support) in infant development. METHOD Birth status and medical complication information was collected during the child's NICU stay. Maternal distress was assessed with the Beck Depression Inventory and the Parenting Stress Index at 4 months corrected infant age. Social support was measured with the Dunst Scales at 4 months corrected age. Child development measures were collected at 4 and 13 months corrected age (Bayley MDI and PDI), and at 36 months chronological age (PPVT-R and Achenbach CBCL). RESULTS Medical complications mediated the birth status-outcome relationship at 4 and 13 months, but not at 36 months. The 36-month outcomes were predicted by 4-month maternal distress and social support. CONCLUSIONS Prematurity and VLBW are indirectly related to early developmental outcome through their association with medical complications. However, by 36 months, developmental outcomes are more closely related to aspects of the early social environment than to early physiological factors.
NAD+-induced vasotoxicity in the pericyte-containing microvasculature of the rat retina: effect of diabetes.

PURPOSE It was recently proposed that activation of P2X(7) purinoceptors may play a role in causing cell death in the pericyte-containing microvasculature of the diabetic retina. This hypothesis is supported by the observation that diabetes enhances lethal pore formation in retinal microvessels exposed to synthetic P2X(7) agonists. The goal of this study was to determine whether purinergic vasotoxicity can be triggered by the endogenous molecule nicotinamide adenosine dinucleotide (NAD(+)), which is a substrate for ecto-ribosylation reactions known to activate P2X(7) receptor/channels in other cell types. METHODS Pericyte-containing retinal microvessels were isolated from normal and streptozotocin-injected rats. Trypan blue dye exclusion was used to assess cell viability, YO-PRO-1 uptake was used to identify cells with P2X(7)-induced pores, and ethenoadenosine antibodies were used to detect ecto-adenosine diphosphate (ADP)-ribosyltransferase (ART) activity. RESULTS In freshly isolated retinal microvessels, it was found that extracellular NAD(+), but not its catabolites, caused cell death (half-maximal effective concentration [EC(50)] = 2 nM) by a mechanism involving the activation of P2X(7) purinoceptors and the formation of transmembrane pores. A series of experiments provided evidence that NAD(+), which is not a direct purinergic agonist, serves as a substrate for ecto-ribosylation reactions that subsequently trigger P2X(7)-dependent cell death in the retinal microvasculature. Soon after the onset of diabetes, the sensitivity of retinal microvessels to the vasotoxic effect of extracellular NAD(+) increased by approximately 100-fold. CONCLUSIONS Purinergic vasotoxicity triggered by extracellular NAD(+) is a newly recognized mechanism that may contribute to the cell death observed in the pericyte-containing microvascular of the diabetic retina.
AN EVALUATION OF ELT SITUATION IN HIGHER EDUCATION INSTITUTIONS IN PUNJAB, PAKISTAN

The purpose of this study is to evaluate ELT methods, techniques and to indicate classroom activities in the higher educations’ institutions in Punjab particularly with reference to CLT. This study also focuses to point out hurdles and major training needs for improvement in ELT situation. Teachers of college and university are selected as participants for this study. Data is collected from one hundred and eighteen participants by using a questionnaire combination of open ended and close ended items. Data collected have been analyzed qualitatively and quantitatively in the form of percentage, tables and graphs. The findings show that with other teaching techniques and activities, CLT techniques and activities are also being used in our higher education institutions to some extent and similarly facts and figures about ELT success areas manifest that English language teaching in Punjab, Pakistan is moderately successful with respect to different aspects like reading speed, exam success, oral fluency etc. Teachers identified that conversation with native speaker is not as successful as needed. Teachers face many difficulties but these are manageable with respect to CLT. Mostly teachers suggested teacher training programme, use of new technologies, support from administration, small class size and training with native teachers to improve overall ELT situation.
Perceiving Reconciliation: Child Care Policies and Gendered Time Conflicts

In recent decades, many studies have examined gender-related differences in paid employment and the reconciliation of family and employment. Considering perceptions of time conflicts with regards to work at home and leisure activities, this article contributes to a more encompassing understanding of attitudes toward reconciliation problems. Special attention is given to the role of external child care services. The use of an original data set from 60 Swiss municipalities and hierarchical multiresponse regression models enable an analysis of the various aspects of time conflicts simultaneously, and a consideration of how different policy contexts shape these attitudes. This study provides evidence that the communal provision of external child care is related to gender-specific perceptions of time conflicts. Most interestingly, men seem to be affected most strongly by communal policy conditions, whereby the provision of external child care is related to systematically higher levels of time conflicts.
Flow cytometric analysis of thiazole orange uptake by platelets: a diagnostic aid in the evaluation of thrombocytopenic disorders.

Thiazole orange (TO), a fluorescent dye originally synthesized for reticulocyte analysis, is characterized by a large fluorescence enhancement and high quantum yield on binding to nucleic acids, particularly RNA. In addition, the dye readily permeates live cell membranes. We applied TO staining, followed by fluorescence-activated flow cytometric analysis, to platelets in whole blood samples from hematologically normal subjects and patients with various quantitative platelet disorders. The percentage of TO-positive platelets in 50 control subjects was 8.6 +/- 2.8% (mean +/- SD) ranging from 2.8% to 15.8%. In 21 thrombocytopenic patients whose bone marrow contained normal to increased numbers of megakaryocytes, the percentage of fluorescently labeled platelets was significantly elevated (P less than .0001) to 26.9 +/- 10.9% (range, 13.3% to 57.1%). In contrast, the proportion of positively stained platelets in 23 patients with thrombocytopenia due to impaired platelet production (various conditions with reduced marrow megakaryocytes) did not significantly differ from the controls, whereas the absolute counts of TO-positive platelets were significantly lowered (P less than .0001). Differences in the distributions of the percentage values as well as of the absolute counts for TO-positive platelets between the two patient groups were again highly significant (P less than .0001). Both the sensitivity and the specificity of this method in distinguishing between these categories of thrombocytopenia were greater than or equal to 95%. We conclude that flow cytometric analysis of platelets after staining with TO is a sensitive and specific test that rapidly provides information on the thrombopoietic activity in thrombocytopenic disorders. Our data further suggest that increased amounts of residual RNA characterize platelets released under conditions of "stress thrombopoiesis. "
Determination of the mass of the neutron star in SMC X-1, LMC X-4, and Cen X-3 with VLT/UVES

We present the results of a spectroscopic monitoring campaign of the OB-star companions to the eclipsing X-ray pulsars SMC X−1, LMC X−4 and Cen X−3. High-resolution optical spectra obtained with UVES on the ESO Very Large Telescopeare used to determine the radial-velocity orbit of the OB (super)giants with high precision. The excellent quality of the spectra provides th e opportunity to measure the radial-velocity curve based on individual lines, and to study the effect of possible distortions of the line profiles due to e.g. X-ray heating on the derived radial-velocity amplitude. Several spectral lines show intrinsic variations with or bital phase. The magnitude of these variations depends on line strength, and thus provides a criterion to select lines that do not suffer from distortions. The undistorted lines show a larger radial-velocity amplit ude than the distorted lines, consistent with model predict ions. Application of our line-selection criteria results in a mean radial-vel ocity amplitude Kopt of 20.2±1.1, 35.1±1.5, and 27.5±2.3 km s −1 (1σ errors), for the OB companion to SMC X−1, LMC X−4 and Cen X−3, respectively. Adding information on the projected rotational velocity of the OB companion (derived from our spectra), the duration of X-ray eclipse and orbital parameters of the X-ray pulsar (obtained from literature), we arrive at a neutron star mass of 1.06 +0.11 −0.10 , 1.25 +0.11 −0.10 and 1.34 +0.16 −0.14 M⊙ for SMC X−1, LMC X−4 and Cen X−3, respectively. The mass of SMC X−1 is near the minimum mass (∼1 M⊙) expected for a neutron star produced in a supernova. We discuss the implications of the measured mass distribution on the neutron-star formation mechanism, in relation to the evolutionary history of the massive binaries.
Recovery Style Predicts Remission at One-Year Follow-Up in Outpatients With Schizophrenia Spectrum Disorders

Although people with schizophrenia use various coping strategies, it is largely unknown how their coping style contributes to remission of the illness. The concept of recovery style-either by sealing over or integrating-reflects an important distinction. We wanted to examine whether recovery style predicts remission at a 1-year follow-up. We examined the recovery style, insight, therapeutic alliance, and symptoms in 103 patients with psychotic disorders. To assess the remission status, the symptoms were measured at 6 and 12 months. Logistic regression analyses were used. Results showed that scoring an extra category toward integration (six categories exist) increased the odds of remission 1.84-fold (95% confidence interval, 1.11 to 3.03). Insight and therapeutic alliance were not predictive. Although remission was also predicted by positive symptom levels at baseline, this did not influence the effect of recovery style. In conclusion, independently of symptom levels, insight, or therapeutic alliance, an integrating recovery style increases the odds of remission at a 1-year follow-up.
Work role stressors and turnover intentions: a study of professional clergy in Hong Kong

Work and occupational stress have long been concerns for employees and human resource managers as they cause many negative outcomes. Most of the previous studies on work stress were conducted in Western countries, while limited research has addressed this important topic in the Asian context. In this study, we examine the effects of several work role stressors (i.e. role ambiguity, role conflict, role overload and work–family conflict) on emotional exhaustion, job satisfaction and intentions to leave. Additionally, we test the mediating effects of emotional exhaustion and job satisfaction between the relationship of role stressors and intentions to leave. Data were collected from a sample of 887 professional clergy in Hong Kong. The results of regression analysis show that role stressors have a significant impact on both emotional exhaustion and job satisfaction, which in turn affect respondents' intentions to leave their organization.
American-Japanese Cultural Differences in the Recognition of Universal Facial Expressions

Although the universal recognition of facial expressions of emotion is well documented, few studies have examined how cultures differ in the degree to which they perceive the universal emotions accurately. In this study, American and Japanese judges viewed expressions of six universal emotions posed by both Caucasian and Japanese males and females. In addition, all photos met external criteria for validly and reliably portraying the emotions. Subjects judged which emotions were portrayed and how intensely they were expressed. Results indicated substantial and consistent differences according to the culture of the judges and the emotion portrayed. These findings are discussed in terms of stable cultural dimensions that may influence the perception of emotion.
Ongoing Contact Activation in Patients with Hereditary Angioedema

Hereditary angioedema (HAE) is predominantly caused by a deficiency in C1 esterase inhibitor (C1INH) (HAE-C1INH). C1INH inhibits activated factor XII (FXIIa), activated factor XI (FXIa), and kallikrein. In HAE-C1INH patients the thrombotic risk is not increased even though activation of the contact system is poorly regulated. Therefore, we hypothesized that contact activation preferentially leads to kallikrein formation and less to activation of the coagulation cascade in HAE-C1INH patients. We measured the levels of C1INH in complex with activated contact factors in plasma samples of HAE-C1INH patients (N=30, 17 during remission and 13 during acute attack) and healthy controls (N=10). We did not detect differences in enzyme-inhibitor complexes between samples of controls, patients during remission and patients during an acute attack. Reconstitution with C1INH did not change this result. Next, we determined the potential to form enzyme-inhibitory complexes after complete in vitro activation of the plasma samples with a FXII trigger. In all samples, enzyme-C1INH levels increased after activation even in patients during an acute attack. However, the levels of FXIIa-C1INH, FXIa-C1INH and kallikrein-C1INH were at least 52% lower in samples taken during remission and 70% lower in samples taken during attack compared to samples from controls (p<0.05). Addition of C1INH after activation led to an increase in levels of FXIIa-C1INH and FXIa-C1INH (p<0.05), which were still lower than in controls (p<0.05), while the levels of kallikrein-C1INH did not change. These results are consistent with constitutive activation and attenuated depletion of the contact system and show that the ongoing activation of the contact system, which is present in HAE-C1INH patients both during remission and during acute attacks, is not associated with preferential generation of kallikrein over FXIa.
Non-linear axisymmetric pulsations of rotating relativistic stars in the conformal flatness approximation

We study non-linear axisymmetric pulsations of rotating relativistic stars using a general relativistic hydrodynamics code under the assumption of a conformally flat three-metric. We compare the results of our simulations, in which the space-time dynamics is coupled to the evolution of the fluid, to previous results performed in the Cowling approximation in which the space-time dynamics was neglected. We show that the conformal flatness condition has only a small effect on the dynamics of pulsating relativistic stars and the obtained pulsation frequencies are very close to those expected in full general relativity. The pulsations are studied along various sequences of both uniformly and differentially rotating relativistic polytropes with index N = 1. For small pulsation amplitudes we identify several modes, including the lowest-order l = 0, 2 and 4 axisymmetric modes, as well as several axisymmetric inertial modes. Differential rotation significantly shifts mode frequencies to smaller values, increasing the likelihood of detection by current gravitational wave interferometric detectors. We observe an extended avoided crossing between the l = 0 and l = 4 first overtones (previously known to exist from perturbative studies), which is important for correctly identifying mode frequencies in the case of detection. For uniformly rotating stars near the mass-shedding limit, we confirm the existence of the mass-shedding-induced damping of pulsations and argue that it is still relevant for secularly unstable modes, even though the effect is not as strong as was previously found in the Cowling approximation. We also investigate non-linear harmonics of the linear modes and note that rotation changes the pulsation frequencies in a way that would allow for various parametric instabilities between two or three modes to take place. Although this scenario has been explored before for slowly rotating collapse, it could become very interesting in the case of rapidly rotating collapse, where the quasi-radial mode could be in resonance with inertial modes. We assess the detectability of each obtained mode by current gravitational wave detectors and outline how the empirical relations that have been constructed for gravitational wave asteroseismology could be extended to include the effects of rotation.
