Spontaneous intracerebral hemorrhage: A pediatric case of undetermined etiology and review of literature

Abstract Cerebrovascular disorders, particularly intracerebral hemorrhage (ICH), rarely occur in children. The most common underlying cause for ICH in the pediatric population is arteriovenous malformation (AVM). The best approach to diagnostic evaluation of pediatric ICH is unknown due to its low incidence (2–3/100,000 children). In recent years, early discovery of underlying cause of pediatric ICH has been possible due to a more widespread use of imaging modalities such as computed tomography (CT), magnetic resonance imaging (MRI) and digital subtraction angiography (DSA). We report a case of a 5-year-old boy with a ICH of unknown etiology. He presented with left hemiparesis and left facial droop for one hour. Non-contrast CT scan demonstrated right periventricular hematoma extending to all ventricles. Follow-up MRI, CT angiography and DSA were unremarkable. Laboratory findings including liver function tests, hematologic studies were normal. Screening for hemoglobinopathies was negative. Transthoracic echocardiography was unremarkable. Surgery for ventricular drain placement and intense physical therapy were performed. During the follow ups at 1 and 6 mo of initial admission, repeat brain MRI and magnetic resonance angiography were unremarkable. The complete diagnostic evaluation in children presenting with ICH of undetermined origin is critically important, but still the etiology may not be identified in some cases. AsAVMs are the most common cause of ICHin children andmay rarely regress following hemorrhage, our patient's normal follow-up imaging may be related to such a spontaneous thrombosis of an underlying AVM.
Ethnography, Operations, And Objectual Practice

This paper raises issues around commercial ethnographic praxis and its relationship to social and cultural theory. Michel de Certeau's theories around everyday life practices and Karin Knorr Cetina's concept of postsocial objectual practice are juxtaposed in order to explore how commercial ethnographic practice might seriously engage with theory and transcend some of the assumptions that currently constrain its application within industry.
Verbrennungsinduziertes Wirbelaufplatzen in moderat turbulenten Drallströmungen

Um Emissionen von Gasturbinen zu senken, ist die magere Vormischverbrennung eine der erfolgversprechendsten Masnahmen. Jedoch kann in Vormischbrennern, die Drall zur Stabilisierung der Flamme nutzen, das verbrennungsinduzierte Wirbelaufplatzen zu plotzlichen Flammenruckschlagen fuhren. Um das Auftreten dieses Phanomens erklaren zu konnen, untersucht die Dissertation die Turbulenz-Chemie-Interaktion im Fall moderat turbulenter Drallstromungen. Durch den Einsatz hochmoderner optischer Messtechniken gemeinsam mit numerischen Simulationen wurden Schlusselfaktoren identifiziert. Die neuen Erkenntnisse erlaubten die Definition eines Modells zur Vorhersage der Flammenruckschlage, dessen erfolgreiche Validierung an verschiedenen Brennergeometrien erfolgte.

Screening for Aphrodisiac Property in Local Oyster of Crassostrea iredalei

Oyster has been reputed since ancient time to increase sexual performance. This myth has been around for many years and still going strong until today. However, there is no scientific evidence to support the claim. Therefore, this study was conducted to screen the aphrodisiac property in local oyster of Crassostrea iredalei. Mounting behaviour and assessment of mating were the parameters tested in this study. Three doses; 50, 100 and 200 mg/kg from each aqueous and ethanol extracts of C. iredalei, respectively were administered (i.p.) to male mice for measuring both test parameters. Sildenafil citrate at the dose of 5 mg/kg was used as positive control while physiologic saline solution as negative control. Male mice treated with ethanol extract of C. iredalei showed substantial evidences in the mounting behaviour at the dose levels of 50, 100 and 200 mg/kg compared to aqueous extract. However, only mild aphrodisiac effect was showed with aqueous extract at the dose of 50 mg/kg. Besides, all doses of ethanol extract showed no significant differences (p>0.05) after administration compared to the positive control. This indicated the ability of extract to be as competent as Sildenafil citrate at certain dosages even though Sildenafil citrate produced higher activities than the local oyster. No sperm was observable in all groups for the assessment of mating test. Thus, this study provided preliminary evidence regarding the potential aphrodisiac property of the local oysters that could be used as an alternative therapy to restore male sexual activity.
An ecosystem framework for understanding and treating disease

Abstract Pathogens and cancers are pervasive health risks in the human population. I argue that if we are to better understand disease and its treatment, then we need to take an ecological perspective of disease itself. I generalize and extend an emerging framework that views disease as an ecosystem and many of its components as interacting in a community. I develop the framework for biological etiological agents (BEAs) that multiply within humans—focusing on bacterial pathogens and cancers—but the framework could be extended to include other host and parasite species. I begin by describing why we need an ecosystem framework to understand disease, and the main components and interactions in bacterial and cancer disease ecosystems. Focus is then given to the BEA and how it may proceed through characteristic states, including emergence, growth, spread and regression. The framework is then applied to therapeutic interventions. Central to success is preventing BEA evasion, the best known being antibiotic resistance and chemotherapeutic resistance in cancers. With risks of evasion in mind, I propose six measures that either introduce new components into the disease ecosystem or manipulate existing ones. An ecosystem framework promises to enhance our understanding of disease, BEA and host (co)evolution, and how we can improve therapeutic outcomes.
Mujeres y Geología en España

Muchos de los estudios realizados en los ultimos anos indican que la sensacion de invisibilidad y discriminacion que sentimos las mujeres dedicadas a la ciencia, y especificamente a la Geologia, no es una mera percepcion subjetiva, sino que las cifras estan ahi corroborando estas sensaciones. Los datos de distintos organismos y elaborados por distintas fuentes siempre indican una menor participacion de las mujeres en los organos de gestion, y una mayor dificultad para alcanzar los puestos de trabajo de niveles mas altos. Esto es asi a pesar de que el no de licenciadas de ciencias supera al de los licenciados, pero a lo largo de la carrera profesional se produce una inversion que hace que las geologas “se pierdan” por el camino. En este trabajo se presentan algunas de estas cifras con objeto de llamar la atencion sobre la situacion y discutir en la Mesa Redonda sobre las posibles soluciones. [ABSTRACT] Recent studies on women and science show that the perception that women are less visible and discriminated during their professional careers is real and can be demonstrated with data. This situation affects in particular to women geologists. Data from different sources and organisms indicate that women geologist participate less in decision-making committees and have more difficulties to reach the highest positions that their male colleagues. This occurs even considering that the number of women that finish their degrees in Geology is higher than the number of men. Along their professional career there is an inversion, in which women geologist are lost in the way to top positions. In this paper, we present some data in order to call the attention on this situation and to bring to the table a discussion on the possible measures to correct this situation.
KeyGraph-based BBS for Supporting Online Chance Discovery Process

A bulletin board system (BBS) equipped with KeyGraph is proposed for supporting online chance discovery process. In chance discovery process, it is important that various specialists discuss a KeyGraph to generate scenarios from various standpoints. The proposed BBS enables online discussion, where we can expect large number of participants in comparison with conventional meeting which requires all participants to meet in a meeting room. In order to support online discussion for scenario generation, the BBS has a function of visual annotation on the KeyGraph. The system also provides a function for retrieving similar scenarios based on visual annotations. It is shown by the experiment with test subjects that these functions are effective for supporting chance discovery process.
Revisiting the SNAP Cycle of Food Intake: Investigation Heterogeneity and Diet Quality

Previous research, using data from 1989-91, found that Supplemental Nutrition Assistance Program (SNAP) recipients experienced a decline in caloric intake at the end of the benefit month. This study uses data from the 2007-10 National Health and Nutrition Examination Survey (NHANES) to revisit the question of cyclic dietary intake and quality. Identification of the effect of time since benefits were received is achieved by exploiting the across and within-state variation in distribution of SNAP benefit each month, as well as exogenous variation in NHANES interview dates. Adults and children are considered separately to test for heterogeneity in the relationship between time since benefits were received and food intake. Other subgroups are also examined.
Multi-Decision Sub-Band Voice Activity Detection for Speech Enhancement

This paper compares the performance of the recently developed multi-decision sub-band voice activity detector (MDSVAD) [1], with the ITU G.729B voice activity detector (VAD) scheme [2] and the SNRVAD scheme [3] for a speech enhancement application. The study shows the importance of more detailed VAD decisions in the time-frequency plane to better maintain speech features. This is in keeping with the observation that typically a speech signal will not simultaneously excite all frequency components at any one time instant. Here, the MDSVAD exploits the spectral structure of speech versus background noise to make independent voice activity decisions in separate subbands, resulting in multiple decisions for any frame. Results show that the decisions in separate sub-bands reduce the infamous musical tones significantly in the conventional spectral subtraction algorithm compared to the other two VADs.
The Learning Styles Educational Neuromyth: Lack of Agreement Between Teachers' Judgments, Self-Assessment, and Students' Intelligence

Learning styles (LS) have dominated educational practice since their popularization in the 1970s. Studies have shown that they are accepted by more than 90% of teachers worldwide. However, LS have also received extensive criticism from researchers and academics, due to the poor theoretical justification of the theory, their problematic measurement, and the lack of systematic studies supporting them. The present study tested the hypothesis that teachers’ and students’ assessment of preferred LS should correspond. Moreover, it tested whether teachers’ judgment of LS is driven by the students’ IQ. Both questions were studied for the first time in a systematic fashion within LS research in primary school pupils. Fifth- and sixth-grade pupils (n = 199) were asked to self-assess their preferred LS, while their teachers were asked to provide their own assessment on individual pupils’ LS. No relationship was found between pupils’ self-assessment and teachers’ assessment, suggesting that teachers cannot assess the LS of their students accurately. Moreover, students’ intelligence was not found to drive teachers’ assessment of their learning styles. This study adds to the body of evidence that is skeptical of the adoption of LS in mainstream education.
Java Modeling Color with Uml: Enterprise Components and Process with Cdrom

From the Book: PREFACE: Preface Archetypes, color, and components will forever change how you build Java models. We build Java models with teams of developers. In our day-to-day mentoring, we develop and try out new ideas and innovations that will help those developers excel at modeling. Some of those ideas fall by the wayside. Some provide modest help. Others, according to our clients, are home runs. In this book, we reveal some of our home runs. Chapter 1 explores the importance of color and introduces the color-coding that project teams have been applying with success around the globe. It also introduces the domain-neutral component, a template that youOll see applied again and again in the chapters that follow. Chapters 2Ð5 deliver ready-to-use Java models. These chapters present 61 domain-specific components, each one an interesting teaching by example. Use the components as they are, extend them with plug-ins, extend them by adding your own content, or use them as an outside opinion (comparing and contrasting with your own ongoing work). Chapter 6 delivers a process that integrates Java modeling into the delivery of frequent, tangible, working results. We hope you enjoy this new material!

First Case of Diffuse Leishmaniasis Associated With Leishmania panamensis

Abstract Leishmania panamensis is the most common species of Leishmania in Panama, and it is known to cause cutaneous leishmaniasis, disseminated cutaneous leishmaniasis, and mucocutaneous leishmaniasis; however, it not associated with diffuse cutaneous disease. In this study, we report the first case of diffuse cutaneous leishmaniasis caused by L panamensis.
Two-Year Colleges and Vocational Schools as Sources of Military Manpower

Abstract : This study examines the recruiting potential of two-year colleges and postsecondary vocational schools as a means for meeting the military's needs for nonprior service high school graduates in the next decade. The authors found that these institutions contain sufficiently large numbers of men of enlistment age to make them an attractive recruiting market, and that the majority of their students are potentially high-quality enlistees. Their findings also indicated, however, that in systematic attempts to recruit from these institutions, the military has not substantially increased enlistment rates; that there do not appear to be hot spots across the nation in which recruiting from these institutions has been particulary successful; and that special (and potentially more costly) incentives and recruiting tactics may be needed to increase enlistment rates. The authors conclude that these institutions are far too important as sources of accessions to be ignored, and recommend collecting additionally information to determine whether the quality of enlistees from postsecondary educational institutions warrants the comparatively higher costs of recruiting them. Concludes with table showing numbers of recruits by state, local area and of education.
Behavior-based malware detection

Malicious programs pose a significant problem in today's interconnected world. When malicious programs (malware) were few and far between, in the 1980s and 1990s, detection techniques based on syntactic descriptors (e.g., byte signatures) worked well. Analysts used their expertise to derive signatures for the latest malware outbreak and then these signatures were deployed to users of the detection software. The recent trend of malware for profit has stimulated the creativity of malware writers who now routinely use obfuscation and stealth to help their malware samples evade detection. As a result, we are witnessing a pandemic of malware infections that puts millions of victim machines under the control of attackers and that current detectors are unable to stem. This dissertation presents a series of behavior-based techniques for malware detection that are resilient to the obfuscation tactics exhibited by modern malware. The core element is a mechanism for specifying and detecting malicious behavior independently of any obfuscation artifacts. A new formalism, called malspecs, serves to characterize malicious behavior. A malspec consists of security-sensitive operations necessary to achieve a malicious goal and of constraints on the arguments of these operations, and is usually represented as a graph structure. Malspec detection builds on existing program analysis and verification techniques to achieve sound results. The key challenge is to develop semantic analyses that are oblivious to obfuscation yet achieve good runtime performance. Two techniques based on static analysis are presented in this dissertation to show how to balance detection power with detection overhead. To complement detection, a malspec mining algorithm is developed to extract malicious behavior from a known malware sample with no a priori information or assumptions. Observing that a malspec is the smallest sequence of operations necessary to achieve a malicious goal, the mining algorithm uses a differential dynamic analysis to construct malspecs automatically. Experimental evaluations of these techniques (both for malspec detection and malspec mining) on actual malware samples and benign programs indicate significantly improved detection rates, with only a limited performance impact. The results demonstrate that a principled behavioral analysis is fundamental to malware detection, superseding the inadequate syntactic detection schemes.
Enzymatic Activity Is Not Required for Phospholipase D Mediated TNF-α Regulation and Myocardial Healing

Phospholipase D1 is a regulator of tumor necrosis factor-α expression and release upon LPS-induced sepsis and following myocardial infarction (MI). Lack of PLD1 leads to a reduced TNF-α mediated inflammatory response and to enhanced infarct size with declined cardiac function 21 days after ischemia reperfusion (I/R) injury. Deficiency of both PLD isoforms PLD1 and PLD2 as well as pharmacological inhibition of the enzymatic activity of PLD with the PLD inhibitor FIPI protected mice from arterial thrombosis and ischemic brain infarction. Here we treated mice with the PLD inhibitor FIPI to analyze if pharmacological inhibition of PLD after myocardial ischemia protects mice from cardiac damage. Inhibition of PLD with FIPI leads to reduced migration of inflammatory cells into the infarct border zone 24 h after experimental MI in mice, providing first evidence for immune cell migration to be dependent on the enzymatic activity of PLD. In contrast to PLD1 deficient mice, TNF-α plasma level was not altered after FIPI treatment of mice. Consequently, infarct size and left ventricular (LV) function were comparable between FIPI-treated and control mice 21 days post MI. Moreover, cell survival 24 h post I/R was not altered upon FIPI treatment. Our results indicate that the enzymatic activity of PLD is not responsible for PLD mediated TNF-α signaling and myocardial healing after I/R injury in mice. Furthermore, reduced TNF-α plasma levels in PLD1 deficient mice might be responsible for increased infarct size and impaired cardiac function 21 days post MI.
Clinical and Social Concerns in Treated Patients with Primary Hypothyroidism in Basrah: A Cross Sectional Study

Background: Despite available treatment for hypothyroidism, L-thyroxine replacement therapy in a biochemically appropriate dose does not necessarily relieve patients' symptoms and complaints. The aim of the study was to evaluate the concerns of patients treated with hypothyroidism and to correlate these concerns with different patient characteristics and thyroid biochemical control. Subjects and Methods: one hundred eighteen treated primary hypothyroid patients attending Al-Faiha Specialized Diabetes, Endocrine and Metabolism Center (FDEMC) in Al-Basrah were entering a questionnaire designed to capture personal, anthropometric, biochemical and clinical data. Twenty-four concerns were questioned to the patients who score these concerns on a 4 point Likert scale. Results: The most scored patients' concerns were fatigue, neuropathic pain, lack of weight loss, cold intolerance, breathing problems, and swallowing problems. No statistically significant relations were existed between these concerns and thyroid stimulating hormone (TSH) control, except for a high TSH group which were highly likely to have concerns of feeling sick (OR: 0.27, 95%CI 0.54 to 2.0, p=0.001), neuropathic pain (OR: 0.4, 95%CI 0.17 to 1.6, p=0. 01), cold intolerance (OR: 0.35, 95%CI 0. 0.3 to 1.7, p=0.005), and hair problems (OR: 0.26, 95%CI 0.6 to 2.1, P Conclusion: We cannot rely on the TSH level alone as a marker of optimal treatment outcome in patients with primary hypothyroidism because it does not reflect the concern status of the patients.
