Authors: Jimoh Abayomi , Ojesanmi Abiodun , Olowu Rasaq
Published: November 2020

Introduction: Heavy metals are useful for essential animal tissue metabolism; however, when these metals exist beyond the permissible limits, they cause ecological damage and constitute threat to human health. Freshwater prawns, including Macrobrachium vollenhovenii, are bio-indicators of metal pollution. M. vollenhovenii is an important source of protein and abundant in the Asejire Lake, which serves as a major source of drinking water to people living around the Lake. Aims: This study was therefore designed to examine the concentrations of some heavy metals (Mn, Pb, Cd, Cu and Zn) in water, sediment and different sizes of Macrobrachium vollenhovenii in Asejire Lake, southwest Nigeria. Materials and Methods: Quarterly sampling of M. vollenhovenii, water and sediment was conducted on Asejire Lake in the months of November, February and May. Analysis of the selected heavy metals in the various samples was done using Atomic Absorption Spectrophotometer. Bioaccumulation Factors (BAF) of the metals were also determined. Results: Heavy metals concentration in prawns was in this order: Zn > Cu > Mn > Pb > Cd. Ranked mean concentration of heavy metals in different prawn sizes was large > small > medium. There was no significant difference, at p > 0.05, among heavy metals concentrations in different prawn sizes, except in Cadmium. Pb, Cu and Zn were detected in water, while all the five metals were detected in sediment. Large prawns bioaccumulated the most heavy metals while medium prawns bioaccumulated the least. Cu was the most bioaccumulated heavy metal. Concentrations of Mn, Pb, Cu and Cd were above the FAO limit for prawn; concentrations of Cu and Zn in water were below the WHO limit, while Pb was above the limit. Concentrations of heavy metals in sediment were lower than the FAO limit. Conclusion: These results suggest that prawns and water from Asejire Lake are not safe for human consumption, and it is recommended that proper managerial policy be put in place to check the influx of these metals into the Lake. Keywords: Heavy Metals, Size, Macrobrachium vollenhovenii, Asejire Lake

Authors: Ogunmoye Abdulrazaq
Published: November 2020

Uapaca guineensis Mull. Arg. (Euphorbiaceae) commonly called false mahogany and “Ewe akun” in the western part of Nigeria grows in humid localities, mixed evergreen forest and sea-level up to 1100 m altitude. The study was designed to isolate Betulinic acid (3?-hydroxylup-20-(29)-en-28-oic acid) which is a naturally occurring pentacyclic triterpenoid that exhibited antibacterial, antimalarial, anti-inflammatory, anthelmintic and antioxidant properties from the stem bark and root of Uapaca guineensis. The air-dried and pulverized stem bark and root of U. guineensis (0.5 kg each) were separately extracted with aqueous ethanol (80%) for 72 hour at room temperature, filtered, concentrated on rotatory evaporator at 37 oC and then stored in a desiccator. The ethanol extracts of the stem bark was partitioned successively with n-hexane, dichloromethane and methanol, while ethanol extract of the root was chromatographed directly. The dichloromethane and methanol extracts of the stem bark was also chromatographed. These results in the formation of whitish powder that are UV inactive and also gave single spot each with cerium sulphate. They are coded as DBG-D13 (25.0 mg), MBG-Q3 (6.1 mg) and ERG-E7 (20.0 mg) for dichloromethane, Methanol and Ethanol extracts respectively. The structure was unequivocally established by 1HNMR, 13CNMR, 2D-NMR, IR, UV and MS spectra analysis as well as by comparison of the spectra data with previously reported values. The dichloromethane, methanol and the ethanol extracts all yielded betulinic acid in substantial quantity. The isolated compound is a confirmation to existing information and an addition to the library of organic compounds.

Authors: Chen Minjie
Published: November 2020

Circuit models for multiphase coupled inductors

are summarized, compared, and unified. Multiwinding magnetic structures are classified into parallel-coupled structures and series-coupled structures. For parallel-coupled structures used for multiphase inductors, the relationships between a) inductance matrix models, b) extended cantilever models, c) magnetic circuit models, d) multiwinding transformer models, e) gyrator-capacitor models, and f) inductance dual models are investigated and

discussed. These models represent identical physical relationships in the multiphase coupled inductors, but emphasize different physical aspects and offer distinct design insights. The circuit duality between the series coupled structure and the parallel coupled structure is revealed. Design equations linking these models are compared and unified. The models and design equations are verified through theoretical derivation, SPICE simulation, and experimental measurements.

Introduction. In late 2019 - early 2020, an outbreak of infection caused by a novel strain of beta coronavirus SARS-CoV-2 was reported. The World Health Organization defined the disease as coronavirus disease 2019 (COVID-19). In the Tyumen Region, the first case of COVID-19 was diagnosed on 31/1/2020. The source of infection was a female student who came from Jinan, Shandong province (China). The number and rate of cases were steadily increasing from the 16th week through 28th week in 2020. The highest rate was 36.87 cases per 100 thousand people. Afterwards, the cumulative incidence kept increasing gradually, but not as quickly.The purpose of the seroepidemiological study was to measure the level and to identify the structure of herd immunity against the SARS-CoV-2 virus among the population of the Tyumen Region during the rapid spread of the COVID-19 outbreak.Materials and methods. Volunteers for participation in the study were selected through questionnaire surveys and random sampling. The exclusion criterion was an active COVID-19 infection at the time of the survey. A total of 2,758 individuals were tested for SARS-CoV-2 specific antibodies. The age of the surveyed volunteers ranged from 1 year to 70 years and older.Results of the study. During the active phase of the COVID-19 incidence, the population of the Tyumen Region showed moderate (24.5%) seroprevalence of SARS-CoV-2. At the same time, the tests revealed a high (97.8%) rate of asymptomatic infection cases in seropositive individuals who had never been diagnosed with COVID-19 and did not have history of positive PCR test results or acute respiratory infection symptoms on the day of testing. The maximum level of herd immunity was identified in children aged 1-6 years (34.7%), which was significantly higher compared to the average level of seroprevalence in the entire cohort. In recovered COVID-19 patients, antibodies were detected in 68.2%. In individuals with positive PCR test results, antibodies were detected in 64%. Conclusion. The results of the assessment of the level of herd immunity against the SARS-CoV-2 virus are crucial for prediction of the development trend of the epidemic and for planning specific and non-specific COVID-19 prevention measures.
Causes and consequences of delayed vaccination against pertussis infection in the Russian Federation
Authors: Lomonosova Alena V.
Published: November 2020

Introduction. One of the reasons for the increase of pertussis in the Russian Federation on the background of the widespread coverage of prophylactic vaccinations of more than 95% is a large number of unreasonable medical recusals and parental refusals and, as a result, untimely prophylactic vaccinations against pertussis infection.Materials and methods. We analyzed 5101 emergency notifications for pertussis in children under 17 years of age in Moscow in 2012-2017 and 300 child development histories for children under 14 years of age in two clinics in Moscow. A сase-сontrol study was conducted to assess the relationship between pertussis and the presence of deviations in the immunization schedule.Results. It was found that the level of timely immunization against pertussis did not exceed 5%. Medical (20%) and parental refusals (45%) prevail among the reasons for delayed vaccination. In the structure of medical exemption, the main causes are perinatal encephalopathy, congenital heart defects, intestinal dysbiosis, allergic diseases, anemia and some chronic diseases.Discussion. The main principle for the formation of a full protective immunity from pertussis infection is the mandatory administration of a full primary course of vaccination against pertussis, with the completion of three vaccinations at the age of 10-12 months and mandatory control over the timely receipt of a booster dose no later than the child reaches two years of age. In addition, it is necessary to introduce additional booster doses of pertussis vaccine at the age of 6-7 years, 12-14 years, vaccination of adults every 10 years, as well as consider the introduction of vaccination of expectant mothers in each pregnancy at 27-36 weeks, vaccination for medical personnel and employees who provide child care services.

Modeling the near-field of extremely large aperture arrays in massive MIMO systems
Authors: Csathó Botond Tamás , Horváth Bálint Péter , Horváth Péter
Published: November 2020

Massive multiple-input multiple-output (MIMO) is a key technology in modern cellular wireless communication systems to attain a very high system throughput in a dynamic multi-user environment. Massive MIMO relies on deploying base stations equipped with a large number of antenna elements. One possible way to deploy base stations equipped with hundreds or thousands of antennas is creating extremely large aperture arrays. In this paper, we investigate channel modeling aspects of massive MIMO systems with large aperture arrays, in which many users are located in the near-field of the aperture. Oneand two-dimensional antenna geometries, different propagation models, and antenna element patterns are compared in terms of inter-user correlation, condition number of the multi-user channel matrix, and spectral efficiency to identify key design parameters and essential modeling assumptions. As our analysis reveals by choosing spectral-efficiency as a design objective, the size of the aperture is the critical design parameter.

Menimbang (Ulang) Kekerasan Dalam Alkitab Dari Perspektif Katolik
Authors: Tanureja Indra
Published: November 2020

Abstrak: Kekerasan dalam Alkitab boleh dikatakan merupakan sebuah topik alkitabiah yang unik dan abadi, baik dari sudut pandang akademis maupun spiritual. Orang tidak hanya perlu memahaminya untuk orang lain, tetapi juga untuk diri sendiri. Sejak Marcion di abad pertama sampai saat ini, meskipun sudah amat banyak tulisan dihasilkan, tidak pernah ada suatu solusi yang memuaskan semua pihak. Tulisan ini menawarkan sudut pandang yang jarang disentuh, yaitu sudut pandang Gereja Katolik. Membaca Alkitab sebagai orang Katolik berarti membaca dengan memperhatikan juga ajaran-ajaran Gereja tentang (pokok-pokok tertentu dari) Alkitab sebagaimana terungkap dalam dokumen-dokumen resmi Gereja. Ajaran Gereja khususnya Dei Verbum artikel 11 dan 12 memuat paling tidak pemahaman akan tiga hal yang dapat membuka kemungkinan untuk memahami persoalan ini secara lebih utuh. Pokok-pokok yang dimaksud adalah soal inspirasi, paham tentang Alkitab, dan kesatuan seluruh Alkitab sebagai kunci penafsiran Alkitab dalam Gereja. Pembacaan Alkitab secara menyeluruh menunjukkan bahwa klim kekerasan dalam Alkitab adalah sebuah klim sepihak yang tidak memperhatikan keseluruhan Alkitab sebagaimana dipahami dan di terima Gereja sebagai buku iman.

Abstract: Violence in the Bible could be considered a unique eternal theme in the Bible, be it from academic or spiritual perspective. One needs to understand it not only for helping others, but also for himself. Since Marcion in the first century up to our time, there has been no solution which is acceptable and could satisfy everybody, notwithstanding the abundance literature on this topic. To read the Bible as Catholic means to read it employing the Church’s teachings on the Bible which are found in the official Church documents as the hermeneutical key. The teaching of the Church especially Dei Verbum 11 and 12 offers an understanding on three important points that could be useful for comprehending the topic in a more comprehensive way. Those three points are the notion of biblical inspiration, the Catholic understanding of the Bible and the unity of the Bible. They could be the key to a correct interpretation of the Bible within the Church. The holistic reading of the Bible shows that the claim of biblical violence is actually a one-sided claim that does not pay fair attention to the unity of the Bible as a whole as it is understood and accepted by the Church as the book of faith.

Keywords: Violence in the Bible, Church’s official teaching, Dei Verbum, divine inspiration, notion of the Bible, the unity of the Bible, literary genre.

Cenzura wojskowa w komunistycznej Polsce i jej wpływ na powstanie i funkcjonowanie GUKPPiW
Authors: Patelski Mariusz
Published: November 2020

Najstarszą i najdłużej działająca instytucją kontrolującą media w komunistycznej Polsce była cenzura wojskowa powstała pod koniec II wojny światowej. Służba ta zorganizowana była na wzór cenzury sowieckiej i pod kierownictwem oficerów sowieckiego wywiadu wojskowego – GRU. Cenzorzy wojskowy kontrolowali oprócz wydawnictw wojskowych również media cywilne. Specjalny Wydział Wojskowy funkcjonujący w strukturach cywilnej cenzury – Główny Urząd Kontroli Prasy, Publikacji i Widowisk, odpowiadał za ochronę tajemnicy wojskowej i szkolenie cenzorów cywilnych w zakresie obronności. Oficerowie cenzury wojskowej pod pozorem ochrony tajemnic wojskowych nie dopuszczali do druku informacji o wykroczeniach i przestępstwach dokonywanych przez przedstawicieli wojska, w ten sposób znacząco ograniczali cywilną kontrolę nad siłami zbrojnymi PRL.
Antoni Madej – twórca powojenny? Szczególny przypadek autocenzury
Authors: Krawczyk Jacek
Published: November 2020

Artykuł sygnalizuje problem nieobecności Antoniego Madeja w dziejach literatury polskiej po II wojnie światowej. Za kluczowe dla takiego stanu rzeczy autor tekstu uznaje motywacje wewnętrzne, ale również okoliczności zewnętrzne. Wszystko to pozwala zdefiniować Madeja jako poetę wewnętrznie zaprzeczonego i obiektywnie, ze względu na oficjalny zakaz druku, skazanego na milczenie. Artykuł próbuje przypomnieć dorobek artystyczny Madeja, zachowany w postaci niepublikowanych maszynopisów. Szczególną uwagę poświęca się tu jednemu zbiorowi pisanemu w celi więziennej, noszącemu tytuł Liryki więzienne. Przegląd zawartości tego zbioru ma na celu ukazanie doświadczenia autora, ale też kształtu wrażliwości poety i specyficznej perspektywy rozumienia losu ludzkiego jako takiego.
Touching Images. Proszę dotykać
Authors: Mikurda Kuba
Published: November 2020

Artykuł opisuje różne formy dotykowej relacji z obrazami – od dosłownych po metaforyczne. W pierwszej części, poświęconej dotykaniu obrazów, autor sugeruje, że zakaz dotykania obrazów wynika z obawy przed naruszeniem sublimacyjnej ramy, która wydobywa obraz z pola wizualnego, wprowadzając dyskretne pęknięcie między obrazem a resztą rzeczywistości, czyniąc z niego figurę na tle. W drugiej części, poświęconej byciu dotykanym przez obrazy autor przywołuje taktylne eksperymenty w filmie i sztukach wizualnych, a także omawia koncepcję obrazu haptycznego Laury U. Marks.
The Vagaries of Imagination: Robert Smithson’s Hotel Palenque and the Early Poetry of William Carlos Williams

The author considers a slidework project by Robert Smithson entitled Hotel Palenque as an introduction to the work of poet William Carlos Williams. Both the aesthetics of Smithson’s project and the theoretical quandaries it brings into focus have a lot in common with what Williams was doing in the late ‘teens and early twenties, coining a radically new style for himself and simultaneously engaging meta-poetic questions in his essays, his book of improvisations, Kora in Hell, as well as in the prose passages included in the first edition of his famous volume of poetry – Spring and All.

Statues and Status Quo. Time of Monuments in the United States
Authors: Zaremba Łukasz
Published: November 2020

In 2015, an armed young white man entered the church in Charleston and killed nine African-Americans. He was guided by racist motives, modeled on Confederate soldiers, and had previously been willing to photograph himself with the Confederate flag. This event once again triggered a discussion in the United States not only about the ideological but also material heritage of the Confederacy states, including the monuments ubiquitous in the cities of the South: memorials to Confederacy leaders but also to anonymous soldiers. These monuments have become the subject of stormy disputes. Some of them were removed by the authorities (New York, New Orleans), some were overthrown in grassroots actions by activists (including Durham and Chapel Hill, referred to in the article); however, a large group was defended by the Republican state authorities.
The article - written from the perspective of visual culture studies - aims to recognize the specificity of the monument's medium in the context of these disputes. It argues that the most important characteristic of the medium considered obsolete today (static, unchangeable, heavy, physical, public, etc.) is its ability to present itself as natural, eternal, "historical". These monuments do not only serve to distort the history of civil war in the states of the South (particularly by erasing slavery from it). At the time of their creation - several decades after the war - they were tools of an aggressive policy of segregation and were intended to emphasize the domination of whites and the permanence of pre-war racial divisions.
The analysis of a contemporary artistic "monumental" intervention - Kehinde Wiley's Rumors of War, unveiled in December 2019 - will help in recognizing the specificity of the monument's medium. This work, from the perspective of art criticism falling into the traps of politics of representation, from the perspective of visual culture studies turns out to be an important guide, entering into a complicated dialogue with the monuments of five Confederate leaders still present at the Monument Avenue in Richmond, the capital of the secessionists.
Rethinking Paleolithic Visual Culture throughout immersive technology: The site "Cueva de las Manos" as a virtual "Denkraum" (Patagonia, Argentina)
Authors: Gutiérrez De Angelis Marina , Winckler Greta , Bruno Paula , Guarini Carmen
Published: November 2020

The discussion about the concepts of cave art and painting settled the basis of the project in the archaeological site of Cueva de las Manos in Argentina. The team uses an immersive technology of VR and the 360° video as a methodology to explore visuality understood as a corporal act. Our hypothesis maintains that the concept of “aesthetic experience” is not exclusively artistic, in its modern sense. The immersive medium allows users to experience the Cave, as a Virtual Denkraum, the spatial and cinematic sensoriality of the image, that poses open questions, instead of the need to decode meaning in the pictures.

Single-cell cloning through limiting dilution can establish a population of cells with homogenous transgene expression for exploring protein function. Here, we describe step by step optimized protocols for generating clonal stably expressing using crude lentiviral supernatant in Jurkat cells. Although the protocol is for general use, we will detail how to create stable cell lines based on Jurkat cells expressing IRF5 spliced isoform. These protocols will be broadly useful for researchers seeking to apply overexpression by viral transduction and generation of stable clone to study gene function in mammalian cells.
Wpływ interleukiny 6 na sen i chorobę Alzheimera
Authors: Kubera Marta , Curzytek Katarzyna
Published: November 2020

Interleukina (IL)-6 charakteryzuje się szerokim, plejotropowym działaniem nie tylko na komórki układu odpornościowego, ale na szereg innych komórek, w tym komórki ośrodkowego układu nerwowego. Cytokina ta oddziałuje na komórki poprzez 2 rodzaje receptorów: mIL-6R?, transbłonowy receptor (droga klasyczna), oraz jego rozpuszczalną formę sIL-6R? (transsygnalizacja). Wywoływana przez IL-6 transsygnalizacja jest odpowiedzialna za neurodegenerację, podczas gdy klasyczna sygnalizacja pełni rolę regeneracyjną i protekcyjną w tkance nerwowej. Komórki mikrogleju przejawiają działanie prozapalne prawie wyłącznie w wyniku transsygnalizacji. IL-6 zwiększa popęd snu zgodnie z rytmem dobowym i sprawuje kontrolę nad wzorcem snu. Bardzo poważne zaburzenia snu dotykają większości osób chorych na chorobę Alzheimera (AD) sprzyjając odkładaniu ? amyloidu (A?). Badania in vitro wskazują na szkodliwą rolę transsygnalizacji IL-6-sIL-6R w AD opartą o zwiększanie A? i hiperfosforylację białka tau, a badania in vivo przeciwnie, wskazują, że IL-6 umożliwia komórkom mikrogleju degradację fibrylarnego A?.

L'Arctique est la région du globe qui s'est réchauffée le plus vite au cours des trente dernières années, avec une augmentation de la température de surface environ deux fois plus rapide que pour la moyenne globale. Le déclin de la banquise arctique observé depuis le début de l'ère satellitaire et attribué principalement à l'augmentation de la concentration des gaz à effet de serre aurait joué un rôle important dans cette amplification des températures au pôle. Cette fonte importante des glaces arctiques, qui devrait s'accélérer dans les décennies à venir, pourrait modifier les vents en haute altitude et potentiellement avoir un impact sur le climat des moyennes latitudes. L'étendue de la banquise arctique varie considérablement d'une saison à l'autre, d'une année à l'autre, d'une décennie à l'autre. Améliorer notre capacité à prévoir ces variations nécessite de comprendre, observer et modéliser les interactions entre la banquise et les autres composantes du système Terre, telles que l'océan, l'atmosphère ou la biosphère, à différentes échelles de temps. La réalisation de prévisions saisonnières de la banquise arctique est très récente comparée aux prévisions du temps ou aux prévisions saisonnières de paramètres météorologiques (température, précipitation). Les résultats ayant émergé au cours des dix dernières années mettent en évidence l'importance des observations de l'épaisseur de la glace de mer pour prévoir l'évolution de la banquise estivale plusieurs mois à l'avance.

Surface temperatures over the Arctic region have been increasing twice as fast as global mean temperatures, a phenomenon known as arctic amplification. One main contributor to this polar warming is the large decline of Arctic sea ice observed since the beginning of satellite observations, which has been attributed to the increase of greenhouse gases. The acceleration of Arctic sea ice loss that is projected for the coming decades could modify the upper level atmospheric circulation yielding climate impacts up to the mid-latitudes. There is considerable variability in the spatial extent of ice cover on seasonal, interannual and decadal time scales. Better understanding, observing and modelling the interactions between sea ice and the other components of the climate system is key for improved predictions of Arctic sea ice in the future. Running operational-like seasonal predictions of Arctic sea ice is a quite recent effort compared to weather predictions or seasonal predictions of atmospheric fields like temperature or precipitation. Recent results stress the importance of sea ice thickness observations to improve seasonal predictions of Arctic sea ice conditions during summer.

Attitudes toward statistics have received a great attention by academic and researcher in statistics and mathematics education. This paper investigates students’ attitudes towards statistics in one of the Malaysia higher education institution and determined the factors that explain the attitude of students toward statistics. Stratified sampling method was used to select 274 respondents from 18 classes Elementary Statistics course. The attitudes toward statistics were measured using the Survey Attitude Towards Statistics (SAT-36) scale. Factor analysis was applied to identify the factors on students’ attitude toward statistics. Findings from factor analysis revealed that seven factors that explain the attitude of the students were self-determination, cognitive competence, effort, value of statistics in professional life, difficulty, statistical solving and value of statistics in everyday life. The results suggested that statistics should be demonstrated in more practical way for developing more positive attitude towards statistics. This could further promote the learning process and students’ ability to apply the statistical concepts.

Nilai korelasi adalah 1.00 iaitu nilai skor yang sempurna bermaksud mempunyai hubungan antara penggunaan bahan multimedia interaktif 3D animasi dan minat dalam mata pelajaran Sains murid Tahun 5. Data analisis Korelasi Pearson menunjukan hubungan yang sangat lemah antara minat dan pencapaian murid dalam mata pelajaran sains. Ini bermaksud, minat tidak mempengaruhi pencapaian murid sepenuhnya. Pencapaian murid juga bergantung kepada faktor-faktor yang lain. Keseluruhannya, dapatan kajian ini menunjukkan bahawa penggunaan multimedia interaktif 3D animasi ‘Scratch’ dalam mata pelajaran sains dapat memberi kesan yang positif dari segi penggunaannya.
Discrepancy of Nerve Cells to Form Ataxia, A Rare Neurological Disease, Intimated With Sub Population of Regenerative Cells to Amend Flaws
Authors: Kumar K R Prithiv
Published: November 2020

Discrepant results due to lack of phenotype-specific species to species relevance to pharmacological results from in vitro cell testing cause inappropriate approaches to treatments to rare conditions in the brain. One such condition is Friedrich Ataxia. The prime focus is on this extreme condition, a neurodegenerative condition that sets precedence for clinical trials. Compounds such as nicotinamide and resveratrol were selected and used in the treatment of Ataxia, the condition shows no improvement. These compounds contracted various responses in iPSC derived neuron generation and more discoverable approach to drug delivery system in vitro conditions. The cell types from iPSC were considered nonrelevant for the disease derived from fibroblasts and more relevant to disease derived from neurons differentiated iPSC cells. This above illustrates the value of utilizing human iPSC cells to improve drug discovery and cure. The over the reacting theory of human iPSC cells are advanced further to discover the potent application of stem cells and further discuss the feasibility of transplantation of Friedrich Ataxia(FA) patients bone marrow-derived mesenchymal stem cells to discover the GAA expansion and reduced FXN and mRNA expression. There is scope for discussion for the assessment of the proliferative ability of pluripotency of FR from bone marrow. The characteristics of bone marrow in vitro differentiation have two types of cells, peripheral neurons, and cardiomyocytes. Also, this chapter leads to series of discussions on the need for testing applications on bone marrow mesenchymal stem cells, mutated gene correction that will play a critical role in gene-based cell therapy, and human artificial chromosomes intact with FXN genes differentiated into neurons or cardiomyocytes.
Uterine Endometrial Sarcoma with Carcinomatosis Treated with Iterative Surgery Associated with Systemic and Intraperitoneal Chemotherapy
Authors: Berkane Salah
Published: November 2020

Introduction: Endometrial sarcoma is a rare condition, affecting women in their 60s. If total hysterectomy associated with bilateral adnexectomy is the standard treatment and can control the disease when it is localized in the uterus, at the peritoneal localization stage its prognosis becomes more negative with reduced possibilities of resection and overall survival at 5 years, therefore, the same with rates close to 30%. We report two cases of endometrial sarcoma with peritoneal localizations managed with a multidisciplinary approach and in several steps or multimodal approach associating a cytoreduction preceded or associated with systemic chemotherapy and intraperitoneal chemotherapy. These two advanced tumours were cured with this approach and at the final step, no deposit tumor were present. The global survival is respectively of 28 months and 63 months.

Conclusion: this approach seems to be efficient in front of the advanced stage of endometrial sarcoma and we think that it must be adopted for a great number of patients to improve the survival and quality of life.
