Intracranial teratomas are tumors that occur mainly in childhood and extremely rare in adulthood. They account up to 50% congenital CNS tumors. In this article a case of mature teratoma in 33 year-old female patient with progressive visual impairment is presented. Differential diagnosis at preoperative stage was difficult. Outcome analysis of neuroimaging study method and clinical picture provided evidence of epidermal cyst. Transnasal endoscopic approach as a treatment method was chosen, but during the surgery the atypical tissue for epidermal cyst was identified with tight adhesion to the right internal carotid artery which limited the extent of surgical tretment. Pathohistological and immune histochemical study detected mature teratoma. Detailed visual impairment dynamic and instrumental methods of diagnosis during postoperative supervision are presented in the article. The choice of management, namely, surgical intervention using extended endoscopic transnasal approach is considered to be controversial and risky among different authors taking into account intraoperative characteristics of this tumor.

Published: April 2021

The intracerebral hemorrhage is associated with severe complications and high mortality. Currently there are no effective methods of treatment of this disease while the standard collagenase model of intracerebral hemorrhage is not described sufficiently.
Objective. To analyze morphological characteristics of the collagenase model of intracerebral hemorrhage, and develop the regression formula predicting the hemorrhage volume based on the results of behavioral tests.
Materials and methods. The experiments were carried out on 7 white male rats weighing 250-400 g aged 11-13 months. All animals underwent surgery to simulate intracerebral hemorrhage. Rats were anesthetized and then, stereotactically, using a needle with a diameter of 0.47 mm, 0.2 units of collagenase type IV were slowly injected into the left striatum. The day after the intracerebral hemorrhage, functional disabilities developed in rats were studied using beam walking test, neurological score test and adhesive removal test. Immediately after performing behavioral tests, the rats were sacrificed by decapitation. After the brain formalin fixation, serial sections on a vibromicrotome of 200 µm thick each in the anteroposterior direction with following morphological examination were made.
Results. It was revealed that the collagenase model of intracerebral hemorrhage is associated with a large variability of the hemorrhage volume. It also had an irregular rugged shape and marks of repeated diapedetic hemorrhages of about 0.6 mm depth. The center of intracerebral hemorrhage along the anteroposterior axis was in average 0.5 mm posterior of the actual site of collagenase injection.The combined use of the neurological score test, the beam walking test and the adhesive removal test in the collagenase model can help estimate the probable intracerebral hemorrhage volume on the 1st day using the regression formula.
Conclusions. Technical details identified in our study can help researchers in planning and conduction of correct experiments related to intracerebral hemorrhage.

Published: April 2021

Inflammatory bowel disease IBD (Crohns disease CD, ulcerative colitis UC) immune-mediated diseases of the digestive tract of unknown etiology. The basis of the pathogenesis of IBD is a violation of the protective mechanisms of the intestinal barrier as a result of a complex interaction of environmental factors, a genetic predisposition and defects in the activation of the immune response in the lymphoid tissue of the intestinal mucosa. Three groups of antibodies are detected in the sera of IBD patients: autoantibodies, antimicrobial antibodies and antibodies to peptide antigens. In CD, the most useful diagnostic markers are ASCA; in UC patients pANCA. Antibodies are not among the diagnostic criteria for CD and UC, the diagnosis of which is traditionally made on the basis of a complex of clinical, radiological, endoscopic and histological signs, but can be used as useful additional non-invasive markers for early diagnosis, assessment of clinical phenotypes, prognosis and effectiveness of treatment of these diseases.

Published: April 2021

Liver fibrosis develops as a result of chronic liver damage of various etiologies, is characterized by excessive synthesis of connective tissue by activated stellate liver cells. The toxic effect of alcohol is one of the most significant and common etiological factors worldwide. Stellate cell activation results from the interaction of multiple molecular fibrogenic pathways triggered by intracellular and extracellular, hepatic and extrahepatic stimuli. Data analysis showed that knowledge about these abnormal pathways and biomolecular processes may further contribute to the improvement of approaches to assessment of disease prognosis and treatment of alcoholic liver disease.

Authors:   Renault Technologie Roumanie, LITA Daniel , IVAN Florian ,   University of Pitesti
Published: April 2021

One of the modern methods of reducing pollutantemissions and increasing dynamic performance is the implementation of distribution phase variation systems for both the intake valve and the exhaust valve, called combined VVT, applied over a wide range of engine operation regimes. The paper aims to highlight how such a solution leads to improved dynamic performance and reduced chemical pollution. Achieving this goal involved experimental investigations into a small class cars SIE. The variants of combined VVT (intake & exhaust), research methodology and an analysis of experimental results on a wide range of functional regimes are presented. It is concluded that such a solution can lead by implementation on engines to remarkable results both in terms of NOx reduction and in terms of dynamic performance (torque and power).

Published: April 2021

Este artigo apresenta um delineamento bibliográfico sobre a Divulgação Científica (DC) no Ensino de Química cujo objetivo foi identificar e analisar as propostas dos estudos sobre esta temática. Artigos completos publicados em periódicos científicos nacionais e internacionais classificados pelo Qualis da Capes em A1 no intervalo de onze anos através da técnica de Análise de Conteúdo fundamentada em Bardin (2011) foram analisados. Encontramos cinco categorias referentes às propostas dos estudos sobre a temática da DC no Ensino de Química. Constatamos que a DC se configura como um objeto de estudo incipiente no Ensino de Química, uma vez que localizamos dezessete trabalhos em um conjunto de quarenta periódicos. Observamos que a maior parte deles propõe o uso da DC para a construção de conceitos químicos, enquanto as experiências na área de formação de professores de Química são relatadas com menor frequência. Os resultados sugerem que a escassez de pesquisas com esse escopo precisa ser suprida, especialmente no campo da Formação de Professores, considerando a importância de fomentar docentes de Química sobre a temática da DC e sobre o uso de ferramentas dessa área.

Embora haja certo otimismo com relação à participação da mulher na ciência, pesquisas apontam diversos entraves para o alcance da igualdade. Nesse aspecto, destaca-se a escola como espaço privilegiado de intervenção, auxiliando estudantes e professores a romper com os estereótipos de gênero. Tendo em vista o processo histórico de exclusão das mulheres, este trabalho tem como objetivo investigar as percepções de estudantes da 2ª série do Ensino Médio de uma escola pública estadual do Município de Goiânia/GO sobre a presença das mulheres na ciência, com vistas a identificar a proximidade do tema na educação básica. A pesquisa possui abordagem qualitativa, utilizando a análise de conteúdo temática. Os resultados indicam que os estudantes possuem uma visão estereotipada de ciência e cientistas, associando a ciência a homens, e têm dificuldade de citar nomes de cientistas mulheres, principalmente as brasileiras. Ademais, a temática mulheres na ciência não é comum a eles, sobretudo na escola, o que reforça a necessidade de inserção desse tema no contexto escolar.

Published: April 2021

Background: The patient's follow-up is a significant challenge for managing psychiatric illness, especially psychotic disorders. Although many factors affect patients' clinical non-attendance with psychosis, the approach of patients and their families toward medication influences treatment follow up. The study evaluates the patient's and family's approach regarding OPD follow up and the effect of SMS reminder on OPD follow up of patients with psychosis.

Methodology: This study was conducted on a psychotic patient attending OPD at Karwan e Hayat, Karachi. A total of 248 patients were randomly divided into two groups, the SMS reminder group and the treatment-as-usual or control group. Computer-based SMS to improve patient's follow-up was sent in Urdu and English to the SMS group. A total of four reminder messages were sent to the SMS group within 15 days of each clinical appointment over a period of 24-weeks, while no message was sent to the control group.

Results: All patients (Intervention & Control groups) were divided further into two groups based on the caring family approach reflected through several follow-ups, including a poor follow up group with less than five visits and an appropriate follow-up group having five or more than five visits. The impact of SMS follow-up reminders on both groups was observed through OPD follow-ups. At baseline, all groups were comparable, but after a 3-month appropriate group of intervention were found with a significant (p=0.053) increase in the number of follow-ups compared to patients with poor follow-up groups.

Conclusion: It is concluded from the study results that the SMS reminders are an effective intervention in those psychotic patients and families who have a positive approach to illness.

Background: Recent advances in imaging technology has made it possible to diagnose abdominal masses in the early stages along with accurate image-guided localization of biopsy sites. Contrast-enhanced Computed tomography (CECT) abdomen is one such imaging tool. This study aims to establish the diagnostic accuracy of CT scans in detecting Wilm's tumour.

Methodology: This descriptive cross-sectional study was conducted in the Department of Radiology, Sindh Institute of Urology and Transplantation (SIUT), Karachi, from 20-10-2018 till 04-20-2019. A total of 196 patients who were clinically suspected of renal masses were included in this research project. CECT scan abdomen was acquired. The final diagnosis was based on histopathology.

Results: Mean age in our study was 13.4±5.7 months. 104 (53.1%) were male, and 92 (46.9%) were female, respectively. Moreover, out of 196 patients, sensitivity, specificity, both the positive and negative predictive value along with diagnostic accuracy of CECT scan for diagnosis of Wilm's tumour by taking histopathology as the gold standard was found to be 93.4%, 91.8%, 95%, 89.4% and 92.8% respectively.

Conclusion: It is concluded from the study results that the Abdominal CECT scan, despite its high radiation dose, is relevant and accurate in making a diagnosis of Wilms tumour, making it significantly helpful in early disease detection in poor resource settings such as ours where patients usually present late for treatment.

Published: April 2021

Motivation/Background: In this paper we aimed at clinically analyzing a patient diagnosed with paranoid schizophrenia, who also displays features specific to multiple personality disorders, in the context of a presentation whose key topic is sexuality. Given the global prevalence and the severity of schizophrenia, it is increasingly important to appropriately adapt and identify the patients' clinical and non-clinical personality profile. This paper also aims at making the profile of a patient diagnosed with axis I disorder ever since the age of 19, who also has got traits specific to certain personality disorders. At the same time, the work provides an interpretation of the behaviour from the psycho-dynamic point of view.

Method: The following instruments were used for performing the analysis: a clinical interview, heteroanamnesis, psychological tests, clinical course monitoring, psychodynamic interpretations, defence mechanisms identification, psychiatric observation and treatment.

Results: Based on the materials aforementioned, it has been established a possible diagnosis which includes multiple disorders: Antisocial Personality Disorder, Histrionic Personality Disorder, Schizotypal Personality Disorder, Obsessive Compulsive Personality Disorder, Cotard Syndrome, Kandinsky-Clérambault Syndrome. and there were identified defense mechanisms and coping strategies, under the influence of sexuality and sadomasochistic impulses.

Conclusions: It is highlighted the clinical picture of a patient with paranoid schizophrenia, who presents symptoms for differential diagnoses, with disorganized discourse focused on sexuality, with delusional ideation, psychotic manifestation, but also with high suggestibility, especially on the paternal line

Published: April 2021

The case of patient V is one you want to dig for, being an example in which a Cluster B disorder (i.e., borderline personality disorder) is also accompanied by elements from Cluster A (such as those in the paranoid area). Symptoms from the dependent personality can be involved.

Objective: The presentation of a medical case of an 18-year-old young man, initially diagnosed at the age of 16 with Bipolar Affective Personality Disorder, and whose personality structure is better explained by a Borderline Disorder is the aim of the present article.

Method: The patient was hospitalized involuntarily. He was under medical supervision and treatment. He also underwent specialized investigations (EEG, brain CT), psychological and personality tests, as well as daily monitoring. Throughout the procedure there have been a collaboration with his family and the authorities.

Results:  From the detailed anamnesis and the reconstruction of the significant life events, a borderline personality structure emerged, having a paranoid core that provided V the capacity of being goal-oriented. The personality scales also showed elements of an antisocial nature, manipulation and desire to be socially liked. Psychodynamic interpretations show an emotional flattening, avoidance of being in touch with he's own emotions and feelings, his unconscious mind housing an unbearable pain.

Conclusions: The diagnosis of Bipolar Personality Disorder, sustained two years ago, is refuted, the patient being included in an axis II frame (i.e. borderline personality with a strong paranoid core and pathology of addiction)
Quantum Organizations with Islamic way forward

Published: April 2021

Firstly, this paper describes a phenomenon of transnational organization and general condition of world and ‘man in the world’. For developing a comprehensive framework, it presents authentic literature review beginning from modernity to post modernity using the hermeneutic-interpretivism research tradition to show the similarities between modernism and post modernism. By revealing the missing link in the quantum paradigm of ralph Kilmann (scholar of quantum organization) on one hand, it develops the possibility of reviving revealed knowledge back into the main frame knowledge of organization theory, on the other hand. By raising and addressing the question of how can the revealed knowledge addresses the current economic dilemma, the paper describes the three lenses available used to understand natural world, socio economic world and behavioral world in Newtonian verses quantum assumptions on organization theory   along with their implications. For cross fertilization of ideas and better understanding of God, cosmos and human it presents an alternative of Islamic way forward suggested by scholarly views from East and West. To further substantiate, it presents the stunning insights from the renowned wisdom traditions (pragmatic civilizations) to highlight why religions matter to show (the levels of reality and levels of selfhood as well as relationship between Necessity being and contingent being), responding the situation of power and domination prevalent in organizing world by suggesting historical/civilizational ethical mode and adopting psycho, spiritual-pragmatic approach with holistic world view (Big picture).

Published: April 2021

The study aims to find out a general description of mustahiks of old-age insurance program from National Zakat Agency (BAZNAS) of Tanah Datar Regency and to analyse the legal status of the program from Islamic law perspective. The old-age insurance program is distribution of consumptive zakat permanently throughout life for the elderly. The researcher used a survey method. The results showed that the old-age insurance program is directed to meet the basic needs of elderly mustahiks. The characteristics of the elderly mustahiks are as follows: 90% are women, 45% are classified as the old-old, 50% have never attended school, 60% are sick, 85% are non-potential elderly people, 55% live in unworthy shelter, 65% live alone, before receiving zakat 80% meet their needs with the help of others, 80% have no income other than zakat. These facts support that the consumptive zakat for the elderly must be continued, because it greatly helps elderly welfare. Although there is no specific argument regarding zakat for the elderly, it doesn’t contradict the provisions of Islamic law. If the Caliphs Abu Bakr, Umar, and 'Ali decided on a policy of providing compensation for non-Muslim elderly from Baitul Mâl, for Muslim elderly ofcourse even more important. Penelitian ini bertujuan untuk mengetahui gambaran umum dari mustahik program jaminan hari tua dari Badan Amil Zakat Nasional (BAZNAS) Kabupaten Tanah Datar dan untuk menganalisis status hukum program perspektif hukum Islam. Program jaminan hari tua merupakan penyaluran zakat konsumtif secara permanen bagi lansia sepanjang hidupnya. Peneliti menggunakan metode survei. Hasil penelitian menunjukkan bahwa program jaminan hari tua bertujuan untuk memenuhi kebutuhan dasar para mustahik lansia. Karakteristik mustahik lansia tersebut adalah sebagai berikut: 90% diantaranya adalah perempuan, 45% diklasifikasikan sebagai lansia berumur sangat lanjut, 50% tidak pernah bersekolah, 60% dalam kondisi sakit, 85% merupakan lansia yang tidak potensial, 55% tinggal di tempat tinggal yang tidak layak, 65% tinggal sendirian, sebelum menerima zakat 80% memenuhi kebutuhan mereka dengan mengandalkan bantuan orang lain, 80% tidak memiliki penghasilan selain zakat. Fakta-fakta ini mendukung bahwa program zakat konsumtif untuk lansia mesti dilanjutkan, karena sangat membantu kesejahteraan lansia. Meskipun tidak ada dalil khusus tentang alokasi zakat untuk lansia, tetapi hal tersebut tidak bertentangan dengan ketentuan hukum Islam. Jika Khalifah Abu Bakr, Umar, dan ‘Ali pernah mengambil kebijakan untuk memberikan santunan kepada lansia non-Muslim dari Baitul Mâl, maka menyantuni lansia Muslim tentu lebih utama lagi.

The purpose of the publication is to summarize the practice of quantitative assessment of the current state and trends in the change of social capital of national economy (SCNE) of Ukraine on the basis of the use of the index system, which comprehensively take into account numerous aspects of its functioning as a basic factor in ensuring stable competitiveness of the national economy (NE), high level of human development, key conditions for prosperity and well-being of all segments of the population. The results of the benchmarking of indices and analysis of the actual level of SCNE are based on data about the factors of current level of the national economy’s formation for individual countries in the process of ensuring in the strategic perspective the UN Sustainable Development Goals – Measuring Social Capital (SC) for Sustainable Development Goals (SDG). For SCNE of Ukraine is inherent in the simultaneous deep commitment of the domestic community to the values of survival (at the level of Russia, Moldova, Romania, Albania, Bulgaria) in combination with a high level of confession of secular rational values (at the level of Lithuania, South Korea, the Czech Republic, Germany, Denmark). Based on the above data, Ukraine has a low level of direct interpersonal social trust (the level of distrust/caution in relations practically exceeds it three times) combined with a low level of trust in political institutions. The necessary information for the assessment of the environment and the general level of development of SCNE of Ukraine is contained in the already mentioned international indices, which in their aggregate comprehensively characterize the subject of our research.
