Concomitant ST-elevation myocardial infarction and deep vein thrombosis in a patient with severe factor XII deficiency: case report and review of the literature.

Since its first discovery in 1955, coagulation factor XII (FXII) deficiency was, quite surprisingly, linked with thrombosis instead of haemorrhage; indeed, John Hageman ultimately died from pulmonary embolism.1 After this, several reports have highlighted the association between both arterial and venous thrombosis and FXII deficiency; however, a causal relationship is still questioned. Here, we report the case of a woman with severe factor Hageman deficiency who was presented with concomitant myocardial infarction and deep vein thrombosis. An 86-year-old woman presented to the Emergency Department because of sudden onset dyspnoea. After initial evaluation, the presence of bilateral femoral vein thrombosis was noted (Figure 1); a computed tomography scan did not reveal pulmonary embolism and was remarkable for the presence of ground-glass bilateral opacities and suspected secondary lesions of the lungs and liver (Figure 2). Electrocardiogram (Figure 3) and cardiac enzymes were consistent with subacute, ST-elevation myocardial infarction (STEMI), and the patient was admitted to Coronary Care Unit. Blood test results at admission are shown in Table 1. Due to the presence of prolonged activated partial thromboplastin time (aPTT), that was interpreted as caused by liver infiltration and insufficiency, the patient was treated with aspirin only and, on fifth day, transferred to our ward for further evaluation.

POU5F1 (OCT3/4) identifies cells with pluripotent potential in human germ cell tumors.

Human germ cell tumors (GCTs) may have variable histology and clinical behavior, depending on factors such as sex of the patient, age at clinical diagnosis, and anatomical site of the tumor. Some types of GCT, i.e., the seminomas/germinomas/dysgerminomas and embryonal carcinomas (the stem cell component of nonseminomas), have pluripotent potential, which is demonstrated by their capacity to differentiate into somatic and/or extraembryonic elements. Although embryonal carcinoma cells are intrinsically pluripotent, seminoma/germinoma/dysgerminoma cells, as well as their precursor carcinoma in situ/gonadoblastoma cells, have the phenotype of early germ cells that can be activated to pluripotency. The other types of GCT (teratomas and yolk sac tumors of infants and newborn, dermoid cyst of the ovary, and spermatocytic seminoma of elderly) are composed of (fully) differentiated tissues and lack the appearance of undifferentiated and pluripotent stem cells. OCT3/4, a transcription factor also known as OTF3 and POU5F1, is involved in regulation of pluripotency during normal development and is detectable in embryonic stem and germ cells. We analyzed the presence of POU5F1 in GCT and other tumor types using immunohistochemistry. The protein was consistently detected in carcinoma in situ/gonadoblastoma, seminomas/germinoma/dysgerminoma, and embryonal carcinoma but not in the various types of differentiated nonseminomas. Multitumor tissue microarray analysis covering >100 different tumor categories and 3600 individual cancers verified that POU5F1 expression is specific for particular subtypes of GCT of adults. No protein was observed in GCT of newborn and infants, spermatocytic seminomas, and the various tumors of nongerm cell origin. In addition, no difference in staining pattern was found in chemosensitive and chemoresistant GCT of adults. These results indicate preservation of the link between POU5F1 and pluripotency, as reported during normal development, after malignant transformation. Therefore, POU5F1 immunohistochemistry is an informative diagnostic tool for pluripotent GCT and offers new insights into the histological heterogeneity of this cancer.
Maternal risk factors for singleton preterm births and survival at the University of Nigeria Teaching Hospital, Enugu, Nigeria.

CONTEXT Risk factors for and survival of singleton preterm births may vary according to geographical locations because of socioeconomic differences and lifestyle. AIMS The aim was to describe maternal risk factors and survival-to-discharge rate for singleton preterm births at the University of Nigeria Teaching Hospital and determine the relationship between maternal risk factors and the survival of singleton preterm babies. SUBJECTS AND METHODS A comparative retrospective review of singleton preterm and term births from January 2009 to December 2013 was carried out. Statistical analysis involved descriptive and inferential statistics at 95% level of confidence using the Statistical Package for Social Sciences (SPSS) version 15 for Windows. P≤0.05 was considered significant. RESULTS A total of 784 births including 392 singleton preterm births (aged 26-36+6) and 392 singleton term births were studied. The mean age of mothers who delivered singleton preterm babies did not differ significantly from that of mothers who delivered singleton term babies (30.2±4.9 years vs. 30.8±4.7; P=0.06). Lack of antenatal care (adjusted odds ratio [aOR]=2.63; 95% confidence interval [CI] 1.92, 6.07), Previous preterm birth (aOR=5.06; 95% CI: 2.66, 9.12), having pregnancy complications including antepartum hemorrhage, preeclampsia/eclampsia or premature rupture of membranes (aOR=5.12; 95% CI: 2.4, 11.8), being unmarried (aOR=2.41; 1.56, 3.71) and nulliparity (aOR=2.08, 95% CI: 1.22, 4.91) were independent risk factors for singleton preterm births. The average survival-to-discharge rate for preterm babies during the period was 38.4%. The mean duration of admission for singleton preterm babies was 16±5.8 days (range: 2-75 days). Whereas survival was dependent on, gestational age at birth (P<0.001) and mode of delivery (P=0.01), it was not dependent on maternal risk factors of parity, marital status, complications of pregnancy, and antenatal care. CONCLUSIONS There was a low rate of survival of singleton preterm babies at the study center and survival was dependent on gestational age at birth and mode of delivery, but not on maternal sociodemographic risk factors for singleton preterm births. Active collaboration between the obstetrician and the neonatologist in deciding when and how to deliver these babies may provide improved chances of survival.
Progress and challenges in predicting protein interfaces

The majority of biological processes are mediated via protein–protein interactions. Determination of residues participating in such interactions improves our understanding of molecular mechanisms and facilitates the development of therapeutics. Experimental approaches to identifying interacting residues, such as mutagenesis, are costly and time-consuming and thus, computational methods for this purpose could streamline conventional pipelines. Here we review the field of computational protein interface prediction. We make a distinction between methods which address proteins in general and those targeted at antibodies, owing to the radically different binding mechanism of antibodies. We organize the multitude of currently available methods hierarchically based on required input and prediction principles to provide an overview of the field.
Frequency and Pattern Reconfigurable Slot Antenna

A novel frequency and pattern reconfigurable slot antenna is proposed. Slot antenna produces a bidirectional radiation pattern, thus a reflector is positioned behind of the antenna to generate a directional radiation pattern. Two switches are placed in the slot to produce three reconfigurable frequency bands: at 1.82 GHz, 1.93 GHz and 2.10 GHz. The introduction of four slits at the edge of the ground plane offers pattern reconfigurability. To tune the beam angles, three switches are inserted into each slit. By manipulating the phase of upper and lower slits in the ground plane, the proposed antenna is capable of reconfiguring its beam to three different angles at 0°, -15° and +15°. The simulated and measured results of reflection coefficient and radiation patterns are presented and compared.
Modeling Spoken Decision Making Dialogue and Optimization of its Dialogue Strategy

This paper presents a spoken dialogue framework that helps users in making decisions. Users often do not have a definite goal or criteria for selecting from a list of alternatives. Thus the system has to bridge this knowledge gap and also provide the users with an appropriate alternative together with the reason for this recommendation through dialogue. We present a dialogue state model for such decision making dialogue. To evaluate this model, we implement a trial sightseeing guidance system and collect dialogue data. Then, we optimize the dialogue strategy based on the state model through reinforcement learning with a natural policy gradient approach using a user simulator trained on the collected dialogue corpus.
Modeling of Ethernet AVB Networks for Worst-Case Timing Analysis

Abstract Ethernet is currently explored as the upcoming network standard for distributed control applications in many different industries such as automotive, avionics and industrial automation. It offers higher performance and flexibility over traditional control bus systems such as CAN and ProfiBus. For distributed control applications, predictable communication timing is highly important which can be problematic using standard Ethernet. The new Ethernet AVB standard aims to improve this by a new scheduling algorithm based on traffic shaping. However, the current AVB standard lacks a formal timing guarantee which is important for safety-critical control applications. As a solution to this, we present a model for Ethernet AVB networks and a transformation into a timing analysis model. Based on the timing model, we apply a compositional performance analysis approach known from the analysis of distributed real-time systems to derive worst-case timing properties and hence timing guarantees of the original Ethernet AVB network. For this, we provide the required formalism for the analysis of the scheduling of Ethernet AVB.
Oriental Brush Simulation using 3 Dimensional Action

Calligraphy is an art of beautiful handwriting seen widely in Oriental countries. The principle tool for oriental calligraphers is the oriental brush which has characteristics different from a pen. The purpose of this paper is to realize a simulation of the expressive oriental brush with a pen tablet and a web camera. Especially we have focused on the effects of the pressure that the calligrapher gives to the oriental brush. The information from the tablet such as the xy-coordinates, pressure, altitude, and azimuth of the pen can be utilized to simulate the oriental brush. However the pen pressure values obtained from the pen tablet are not suitable for an elaborate simulation of the oriental brush in that the calligrapher cannot closely control the pressure. In our system, the calligrapher uses a device brush, i.e., a device pen with attached hairs, as a substitute for the oriental brush. The system measures the z-coordinate of the brush, i.e., the height from the surface of the tablet to the center of gravity of the brush bristles, by using a web camera and utilizes it as a parameter for the brush pressure. The aerial movements of the brush are reflected to the various aspects such as the shape and size of the droplet, ink consumption, ink diffusion, and ink scratchiness, which enables users to write calligraphy with the device brush with a feeling that they use a real oriental brush and to make more delicate expressions.
Trichomonas vaginalis as a cause of urethritis in Malawian men.

BACKGROUND AND OBJECTIVES Trichomonas vaginalis is one of the most common sexually transmitted infections. In Malawi, rates of trichomoniasis in women are high. The prevalence of T. vaginalis infection in men is expected to be high but has not previously been documented. GOALS We sought to determine the prevalence of trichomoniasis in Malawian men with and without urethritis, to evaluate a polymerase chain reaction detection assay for T. vaginalis in urethral swabs and to examine the effect of T. vaginalis infection on excretion of human immunodeficiency virus (HIV) in semen. STUDY DESIGN Men presenting at the Sexually Transmitted Diseases (STD) and Dermatology Clinics in Malawi were enrolled in a cross-sectional study. We compared a polymerase chain reaction-based test for T. vaginalis detection with wet-mount microscopy and culture of urethral swabs. HIV serology was determined by enzyme-linked immunosorbent assay (ELISA), and HIV-1 RNA concentrations in semen were measured by quantitative nucleic acid sequence-based analysis. RESULTS T. vaginalis was detected in 51 of 293 men. The estimated prevalence among symptomatic men was 20.8% and among asymptomatic men, 12.2%. Polymerase chain reaction performed with a sensitivity of 0.82 (95% CI: 0.66-0.92) and specificity of 0.95 (95% CI: 0.91-0.97) compared to wet-mount microscopy and culture. There was no difference in the rate of HIV seropositivity in men with and without T. vaginalis infection. However, in men with symptomatic urethritis, the median HIV RNA concentration in seminal plasma from men with T. vaginalis was significantly higher that in seminal plasma from HIV-positive men without trichomonas.
Mixed H2/H∞ control for networked control system with missing data

In the framework of multi-objective control, this paper presents a mixed H2/Hinfin dynamic output feedback control strategy to the network remote control system with measurement data missing and control data missing. Via matrix inequality method, the sufficient for existence of the dynamic output feedback controller, guaranteeing the closed-loop system has H2 and Hinfin performance simultaneously, is given. A novel arithmetic is put forward to optimize the controller performance via SLPMM (sequentially linear programming matrix method). A numerical example is presented to demonstrate the feasibility of the proposed design approach.
Power of Proteomics in Linking Oxidative Stress and Female Infertility

Endometriosis, PCOS, and unexplained infertility are currently the most common diseases rendering large numbers of women infertile worldwide. Oxidative stress, due to its deleterious effects on proteins and nucleic acids, is postulated to be the one of the important mechanistic pathways in differential expression of proteins and in these diseases. The emerging field of proteomics has allowed identification of proteins involved in cell cycle, as antioxidants, extracellular matrix (ECM), cytoskeleton, and their linkage to oxidative stress in female infertility related diseases. The aim of this paper is to assess the association of oxidative stress and protein expression in the reproductive microenvironments such as endometrial fluid, peritoneal fluid, and follicular fluid, as well as reproductive tissues and serum. The review also highlights the literature that proposes the use of the fertility related proteins as potential biomarkers for noninvasive and early diagnosis of the aforementioned diseases rather than utilizing the more invasive methods used currently. The review will highlight the power of proteomic profiles identified in infertility related disease conditions and their linkage with underlying oxidative stress. The power of proteomics will be reviewed with regard to eliciting molecular mechanisms for early detection and management of these infertility related conditions.
School, family, and community partnerships in teachers’ professional work

Abstract This article discusses the contributions of the international studies in this special issue and presents a few emerging topics on school, family, and community partnerships. The studies in Part I confirm that, across countries, future teachers are inadequately prepared to conduct effective partnership programmes with all students’ families. Part II reports the results of interventions that provide future teachers with opportunities to practice the kinds of communications with parents that they will use as new teachers. In my and colleagues’ studies, several topics of family and community engagement have emerged that will extend and enrich college courses for future teachers and school leaders. These include a redefinition of the ‘professional’ teacher; understanding partnerships as a component of good school organisation; the importance of goal-linked family and community engagement for student success in school; the role of the community in partnership programmes; and the connections of preservice and inservice education for preparing and sustaining productive connections of home, school, and community.
“Where Did I Learn That?” Exploring The Similarity Effect and Children’s Use of Memory Cues for Source Monitoring

An individual’s ability to accurately monitor source (attribute known or remembered information to its particular source or origin) develops gradually throughout childhood. Along with task difficulty (i.e., delay between encoding and retrieval), source similarity is among the utmost hindrance to individuals’ ability to accurately monitor source; specifically, the greater the similarity between sources the more difficult source monitoring judgments have been found to be, and the smaller similarity between sources (i.e., the greater number of differences between sources) the more accurate source monitoring judgments have been found to be. The similarity effect has been said to apply to all age groups, and has been assumed to be especially detrimental for young children. The present research looks further into the issue of source similarity, and suggests that the similarity effect may not be as generalizable as claimed. Specifically, although adults benefit most from dissimilar sources (as the similarity effect predicts), what may be paramount for young children (rather than more differences between sources) are few (at least one) but distinct differences between sources. The present study aims to begin consideration in this area by focusing on visual information. An experimental research design was used to assign 99 participants of different age groups (3-5, 6-8, 18-21) each to two different source-monitoring conditions. Each condition contained two actors, and the number of visual cues that differed between actors varied for each of the conditions (onecue and five-cues). Specifically, the number of visual cues was manipulated such that one pair of actors displayed one distinct visual difference, and the other pair displayed five visual differences. After a short distractor task, participants were interviewed and asked to make source-monitoring judgments about actions performed by the actors within SIMILARITY EFFECT AND MEMORY CUES ii each of the two events. Data were collapsed and analyzed by age group. In line with past literature, an overall/general developmental progression was found to exist in participants’ ability to make accurate source judgments. Contrary to the present proposed theory, there was no significant interaction between age and cue condition; individuals of all age groups were found to be more accurate in the five-cue condition than in the onecue condition (as predicted by the similarity effect). The obtained results in relation to the proposed theory were discussed. Understanding the way that individuals use cues to monitor source can help us further understand developmental differences in source monitoring, clarify the basic mechanisms involved, and highlight other aspects of children’s memory development. In addition, basic research questions concerning the nature of children’s source-monitoring errors may be particularly important to understanding the caveats surrounding forensic interviews with young children.

Automatic Sentence Selection from Speech Corpora Including Diverse Speech for Improved HMM-TTS Synthesis Quality

Using publicly available audiobooks for HMM-TTS poses new challenges. This paper addresses the issue of diverse speech in audiobooks. The aim is to identify diverse speech likely to have a negative effect on HMM-TTS quality. Manual removal of diverse speech was found to yield better synthesis quality despite halving the training corpus. To handle large amounts of data an automatic approach is proposed. The approach uses a small set of acoustic and text based features. A series of listening tests showed that the manual selection is most preferred, while the automatic selection showed significant preference over the full training set.
