Instalação artística como ferramenta interdisciplinar para ensino de desenvolvimento embrionário
Authors: Elias Marcelo Alberto , Trentini Carneiro Fernanda 
Published: February 2020

O ensino de embriologia humana muitas vezes se da de forma distante da realidade dos estudantes, uma vez que muitos dos eventos são extremamente difíceis de serem vistos no microscópio. Assim as aulas acabam ficando maçantes e pouco atrativas para os mesmos, sendo essas construídas a partir de exemplos do livro , vídeos ou materiais digitais trazidos pelos professores. Dentro dessa perspectiva surgiu a ideia de uma atividade interdisciplinar envolvendo a disciplina de arte e biologia e unindo duas turmas de áreas diferentes, técnico integrado em química e técnico integrado em informática. A atividade então contou com cerca de 90 alunos no total que juntamente com os professores construíram um tapete gigante a partir de materiais diversificados onde ficou retratado as fases do desenvolvimento embrionário desde a fecundação até a implantação no útero. Foi possível verificar nessa atividade a importância da interdisciplinaridade construindo laços entre áreas distintas e a promoção da integração entre alunos de áreas tão diferentes como química e informática, a atividade ainda serviu de modelo e popularização da ciência dentro da instituição uma vez que todos os alunos e servidores tiveram contato com a instalação.

Multi-detector computed tomography angiographic evaluation of right ventricular outflow tract obstruction and other associated cardiovascular anomalies in tetralogy of Fallot patients
Authors: Singh Rani Kunti R. , Jain Neeraj , Kumar Sunil , Garg Naveen 
Published: February 2020

PurposeTo evaluate various types of right ventricular outflow tract obstruction associated with tetralogy of Fallot (TOF) with emphasis on the abnormality of pulmonary arterial system and other associated cardiovascular anomalies using computed tomography (CT) angiography.Material and methodsWe retrospectively evaluated 184 consecutive previously diagnosed TOF patients who underwent CT angiography in our department.ResultsInfundibular with pulmonary valvular stenosis was the most common type of stenosis (47.28%) found, followed by isolated infundibular stenosis (34.23%). Isolated abnormality of both right and left pulmonary arteries was also noted. Right side aortic arch (23.91%) was the most common associated abnormality followed by double superior vena cava (9.78%).ConclusionsTOF is associated with various types of right ventricular outflow tract obstruction ranging from infundibular narrowing to isolated narrowing of right or left pulmonary arteries and is also associated with various other congenital abnormalities of the cardiovascular system. CT angiography is an excellent imaging modality, which provides comprehensive analysis of various abnormalities associated with TOF.

Published: February 2020

PurposeThis paper focuses on the role of interventional radiology embolisations in a series of patients presenting with iatrogenic vascular injuries of the lower limbs following orthopaedic interventions.Material and methodsFourteen patients (mean age: 64 years, range 23-90 years) were retrospectively analysed. Clinical presentation consisted of palpable pulsatile mass, pain, reduced lower limb motion, or visible haematoma; 11 patients had also anaemia (haemoglobin < 7 g/dl).ResultsThe time between orthopaedic surgery and embolisation ranged between 0 and 67 days (mean: 15 days). Injured arterial vessels were as follows: inferior gluteal artery (2), superficial external pudendal artery (2), deep femoral artery (1), lateral circumflex femoral artery (3), medial circumflex femoral artery (2), articular branch of descending genicular artery (1), perforating femoral arteries (3), posterior tibial recurrent artery (1), and anterior tibial artery (1). The typologies of vascular lesion were: pseudoaneurysm 57%, bleeding with extraluminal contrast agent blush of the terminal arterial segment 36%, and laceration and bleeding with extraluminal contrast agent blush of the arterial main trunk 7%. Embolising agents adopted were microcoils 57%, glue 14%, microplug 7%, particles 14%, and covered stent 7%. In all cases clinical and procedural technical successes were obtained (100%).ConclusionsFor the management of vascular injuries occurring after different orthopaedic interventions of the lower limbs, endovascular embolisations have proven to be safe and effective; orthopaedic surgeons should be aware of the support that interventional radiology could provide in the case of iatrogenic vascular complications.
T1 and T2 mapping of articular cartilage and menisci in early osteoarthritis of the knee using 3-Tesla magnetic resonance imaging

Published: February 2020

Purpose3-Tesla magnetic resonance imaging (MRI) T1 and T2 mapping to detect and quantify cartilage matrix and meniscal degeneration between normal healthy volunteers and early osteoarthritis patients.Material and methodsA prospective study including 25 patients and 10 healthy volunteers was done. Patients with symptoms of early osteoarthritis and Kellgren-Lawrence grade I-II on plain radiograph were included for MRI knee. Patients with inflammatory arthritis, infection, trauma, and history of knee surgery were excluded. Healthy, normal adult volunteers (preferably age and sex matched) without symptoms of osteoarthritis of the knee were drawn from patient’s relatives/hospital employees/colleagues for MRI knee.ResultsT1 and T2 relaxation time values of articular cartilage and menisci were significantly higher in osteoarthritis patients as compared to healthy volunteers. No significant difference was found in morphological thickness of articular cartilage and menisci in early osteoarthritis patients and healthy volunteers.ConclusionsT1 and T2 mapping are noninvasive MRI techniques reflecting changes in the biochemical composition of cartilage and menisci. T1 values reflect changes in proteoglycan content, and T2 values are sensitive to interaction between water molecules and collagen network. Mapping techniques assess early cartilage and meniscal matrix degeneration in osteoarthritis of the knee, and help in initiating treatment and monitoring disease progression. MRI is a sensitive modality for assessment of pathological changes in articular cartilage. With use of T1 and T2 mapping techniques, it is possible to evaluate the collagen network and proteoglycan content in articular cartilage and meniscal matrix.

Published: February 2020

PurposeTo assess the role of <sup>1</sup>H-magnetic resonance spectroscopy (<sup>1</sup>H-MRS) in the confirmation of pathological complete response after neoadjuvant chemotherapy in breast cancer.Material and methodsForty-seven cases (53.72 ± 8.53 years) were evaluated using magnetic resonance imaging (MRI) and <sup>1</sup>H-MRS with choline (Cho) signal-to-noise ratio (SNR) measured followed by histopathology and ROC analyses.ResultsTwelve patients had complete response, and 35 patients had residual disease. Mean age was 53.72 ± 8.53 years. The mean tumour size before neoadjuvant chemotherapy (NAC) was 4.21 ± 0.99 cm and after NAC was 0.9 ± 0.44 cm.Positive total choline signal (tCho) was detected in all cases. The mean Cho SNR before NAC was 9.53 ± 1.7 and after NAC was 2.53 ± 1.3. The Cho SNR cut-off point differentiating between pathologic complete response (pCR) and the non pCR was 1.95. Dynamic MRI showed 83.3% sensitivity, 65.7% specificity, 45.5% positive predictive value, 92.0% negative predictive value, and 70.2% diagnostic accuracy. Combined evaluation done by using the dynamic MRI and <sup>1</sup>H-MRS showed 91.5% diagnostic accuracy with 75.0% sensitivity, 97.1% specificity, 75% positive predictive value, and 91.9% negative predictive value. ROC curves of Cho SNR showed statistically significant differences between non pCR and pCR with AUC was 0.955, 82.9% sensitivity, 91.7% specificity, 96.7% positive predictive value, 64.7% negative predictive value, and 85.11% diagnostic accuracy.Conclusions<sup>1</sup>H-MRS improves the diagnostic accuracy in the prediction of the pCR after NAC.
Agreement between dynamic contrast-enhanced magnetic resonance imaging and pathologic tumour size of breast cancer and analysis of the correlation with BI-RADS descriptors
Authors: Gemici Aysegul Akdogan , Inci Ercan 
Published: February 2020

PurposeThe purpose of this study was to evaluate magnetic resonance imaging (MRI)-pathology concordance of tumour size in patients with invasive breast carcinoma, with an emphasis on Breast Imaging Reporting and Data System (BI-RADS) descriptors of dynamic contrast-enhanced MRI (DCE-MRI).Material and methodsOf patients who had preoperative DCE-MRI, 94 were enrolled. Concordance between MRI and the pathological findings was defined as a difference in tumour size of 5 mm or less. The greatest dimension was measured by two radiologists, and BI-RADS descriptives were described in accordance. The gold standard was chosen as the pathologic assessment.ResultsTumour measurements determined by MRI and the pathological reports were not statistically different (2.64 ± 1.16 cm, Wilcaxon Z = –1.853, p = 0.064). Tumour sizes were concordant in 72/94 patients (76.6%). The mean difference between the pathological and MRI tumour sizes was –0.1 cm. MRI overestimated the size of 17/94 tumours (18.1%) and underestimated the size of 5/94 tumours (5.3%). Discordance was associated with larger tumour size. Histologic and molecular type of tumours, patient age, histologic grade, lymphovascular invasion or perineural invasion positivity, fibroglandular volume, background parenchymal enhancement, and being mass or non-mass were not associated with concordance. Irregular margin and heterogenous enhancement in DCE-MRI were associated with discordance in logistic regression analysis (p = 0.035, OR: 4.24; p = 0.021, OR: 4.96).ConclusionsTwo BI-RADS descriptors of irregular contour and heterogeneous contrast uptake were found to be associated with tumour size discrepancy. This might be attributed to the dynamic and morphologic specialities of tumours primarily rather than tumour biology.

Published: February 2020

PurposeWe aimed to determine the contribution of the apparent diffusion coefficient (ADC) value in the detection of axillary lymph node metastasis.Material and methodsBreast magnetic resonance of 58 patients, performed in the radiology clinic of our hospital between 2015 and 2017 were examined retrospectively, and 43 lymph nodes in 43 patients were included in the study. They were evaluated morphologically on T1W and T2W sequences, and the lymph nodes showing rounded shape, focal or diffuse cortical thickness of more than 3 mm, and partial or total effacement of fatty hilum were included in the study. Subsequently, their ADC values were measured.ResultsThere were 43 lymph nodes, 20 of which were malignant and 23 of which were benign. While the mean ADC value of malignant axillary lymph nodes was 0.749 10–3 mm<sup>2</sup>/s (0.48-1.342), it was 0.982 10–3 mm<sup>2</sup>/s (0.552-1.986) for benign lymph nodes. When the ADC cut-off value was taken as ≤ 0.753 × 10–3 mm<sup>2</sup>/s, its discrimination power between benign and malignant axillary lymph nodes was as follows: sensitivity – 60%; specificity – 91.3%; accuracy – 76.7%; positive predictive value – 85.7%; and negative predictive value – 72.4%.ConclusionsThere was no significant difference between mean ADC value of 12 lymphadenopathies (LAP) associated with inflammatory breast diseases (granulomatous mastitis and acute suppurative mastitis) and mean ADC value of metastatic lymph nodes. However, the ADC value of lymph nodes showing thickened cortex due to systemic inflammatory diseases was over 1, and there was a statistically significant difference when compared with metastatic lymph nodes.
Determining flow directions in river channel networks using planform morphology and topology
Authors: Schwenk Jon , Piliouras Anastasia , Rowland Joel C. 
Published: February 2020

Abstract. The abundance of global, remotely sensed surface water observations has accelerated efforts toward characterizing and modeling how water moves across the Earth's surface through complex channel networks. In particular, deltas and braided river channel networks may contain thousands of links that route water, sediment, and nutrients across landscapes. In order to model flows through channel networks and characterize network structure, the direction of flow for each link within the network must be known. In this work, we propose a rapid, automatic, and objective method to identify flow directions for all links of a channel network using only remotely sensed imagery and knowledge of the network's inlet and outlet
locations. We designed a suite of direction-predicting algorithms (DPAs),
each of which exploits a particular morphologic characteristic of the
channel network to provide a prediction of a link's flow direction. DPAs
were chained together to create “recipes”, or algorithms that set all the
flow directions of a channel network. Separate recipes were built for deltas
and braided rivers and applied to seven delta and two braided river channel
networks. Across all nine channel networks, the recipe-predicted flow
directions agreed with expert judgement for 97 % of all tested links, and
most disagreements were attributed to unusual channel network topologies
that can easily be accounted for by pre-seeding critical links with known
flow directions. Our results highlight the (non)universality of
process–form relationships across deltas and braided rivers.
A new species of baenid turtle from the Early Cretaceous Lakota Formation of South Dakota
Authors: Joyce Walter G. , Rollot Yann , Cifelli Richard L. 
Published: February 2020

Abstract. Baenidae is a clade of paracryptodiran turtles known from
the late Early Cretaceous to Eocene of North America. The proposed
sister-group relationship of Baenidae to Pleurosternidae, a group of turtles
known from sediments dated as early as the Late Jurassic, suggests a ghost
lineage that crosses the early Early Cretaceous. We here document a new
species of paracryptodiran turtle, Lakotemys australodakotensis gen. and sp. nov., from the Early
Cretaceous (Berriasian to Valanginian) Lakota Formation of South Dakota
based on a poorly preserved skull and two partial shells. Lakotemys australodakotensis is most readily
distinguished from all other named Late Jurassic to Early Cretaceous
paracryptodires by having a broad, baenid-like skull with expanded
triturating surfaces and a finely textured shell with a large suprapygal I
that laterally contacts peripheral X and XI and an irregularly shaped
vertebral V that does not lap onto neural VIII and that forms two
anterolateral processes that partially separate the vertebral IV from
contacting pleural IV. A phylogenetic analysis suggests that Lakotemys australodakotensis is a baenid,
thereby partially closing the previously noted gap in the fossil record.

Three measures to save Dutch youth care
Dutch youth care was decentralized in 2015. Since the transfer to the municipalities, youth care is in a state of deep crisis. There are long waiting lists, even in situations of acute need; there is lack of money, of professional and experienced staff, of adequate care, and of central coordination and guidance. In contrast to Denmark, where youth care was transferred to municipalities in 2007, there was barely time to prepare the transfer in the Netherlands. Moreover, the number of municipalities was not significantly reduced and the funding was extremely cut back. In this article, a number of interventions is being proposed to save what can still be saved. First, funding will have to be substantially increased. Second, the access to youth mental health care should not be a matter of municipal authority.
Numerical simulation of the formation of vortices around rigid cylinders inside a channel using Immersed Interface method
Authors: Alizadeh Asad , Abid Mattie Anas 
Published: February 2020

The numerical simulation of the flow of fluid through one or a set of objects that causes the flow to separate from the surface of them has been the subject of interest by researchers over the past few decades. One of the most important types of these objects is those with a square cross section which have important and diverse applications in different industries. One of the practical applications of these types of streams is flow around chimneys, high-rise buildings, naval structures, suspended bridges, airplane wings, ship propellers and ducts. In this research, the immersed interface method is used which is a non-conforming method to the boundary. Eulerian mesh for fluid field, and Lagrangian mesh for solid field is used. The connection of these two networks is established by the Dirac Delta function. Considering the cylinder as a rigid immersion boundary within the flow. First, the flow around a square cylinder was simulated and we surveyed different flow patterns. The changes in the number of Strouhal and the Drag coefficient were investigated in different Reynolds. The flow around the two cylinders was simulated. It was observed that with the increase of Reynolds number and the gap between cylinders, the vortex shedding (Strouhal number) would increase.
By a Wing and a Tale: Authenticating the Archive in Mohamad-Said Baalbaki’s Al Buraq I The Prophet’s Human-Headed Mount
Authors: McLeod Erin 
Published: February 2020

Al Buraq I : The Prophet’s Human-Headed Mount de Mohamad-Said Baalbaki est le premier volet d’une trilogie qui interroge les pratiques archivistiques et muséales qui prennent forme à partir d’« histoires fortuites ». L’installation complexe de Baalbaki révèle une découverte exceptionnelle : en 1914, l’archéologue allemand Werner von Königswald déterrait d’un cimetière islamique à Jérusalem des objets surprenants, parmi lesquels les os d’une créature ressemblant à un cheval ailé. Von Königswald engagea ses collègues, le paléontologue Hans Wellenhover et l’ornithologue Heinrich Ralph Glücksvogel, dans de nombreux débats scientifiques et théoriques. Ces os avaient-ils appartenu à un cheval difforme ? à un oiseau géant ? ou peut-être même à la créature mythique Al Buraq, le cheval ailé qui guida le Prophète Mahomet ? Al Buraq I met en scène la correspondance et divers objets de curiosité liés à l’excavation, ainsi qu’une réplique du squelette (les vrais os disparurent pendant la Seconde Guerre mondiale). Si sa réception illustre l’héritage d’un mélange culturel qui n’est que trop réel, Al Buraq I est en fait une fabrication totale. L’exposition de l’animal fantastique dans une vitrine classique d’histoire naturelle et les débats subséquents soulèvent des questions centrales quant à la façon dont art et artefact sont construits dans le musée. Les objets d’art « posant » comme des artefacts archéologiques et archivistiques jouent entre le réel et le mythique, entre l’authentique et la contre-façon. Par cette orchestration d’objets, Baalbaki invoque des histoires imaginées qui, par le biais de la représentation muséale, prétendent à l’authenticité. Nous considérons ici les rôles croisés que jouent l’institution, l’artiste et le spectateur dans l’authentification de l’archive.
Ecology and the Ethics and Aesthetics of Collaboration: The Case of Nine Mile Run
Authors: Senechal Carney Lora 
Published: February 2020

Les artistes collaborant avec le public et/ou les professionnels issus de divers domains, dont l’écologie, rencontrent et reformulent le cas échéant les valeurs fondamentales qui sous-tendent le contexte social et politique de projets tels que la réhabilitation du cours d’eau Nine Mile Run menée à Pittsburgh de 1996 à 1999. Les récents débats critiques suscités par l’art collaboratif ont permis à de nouveaux modèles théoriques de se développer, non seulement pour définir ces projets dans le contexte général de la pratique de l’art, mais aussi pour identifier quels sont les critères éthiques et esthétiques peuvant maximiser leur potentiel. Plusieurs des acteurs clés de ce débat sont partis des concepts d’intersubjectivité mis en avant dans les écrits de Félix Guattari, Jacques Rancière et d’autres en proposant de dépasser les oppositions simplistes entre la subjectivité individuelle et la collectivité afin d’aller vers une « politique du sujet » plus productive, pour reprendre les termes de l’écrivain et conservateur Okwui Enwezor. Le commissaire d’expositions Stephen Wright propose un cadre théorique de réflexion particulièrement efficace pour les projets collaboratifs qui, à l’instar du projet Nine Mile Run Greenway, ne se concrétisent pas sous la forme d’« art » visible. Cet article est suivi d’un texte dans lequel l’artiste Tim Collins discute d’un autre projet plus important qu’il a dirigé à Pittsburgh directement après le projet Nine Mile Run auquel il avait collaboré.
