Published: September 2019

A autenticação biométrica suporta diferentes aplicações e tem ganho um papel fundamental nas redes vestíveis por suplantar limitações das interfaces homem-máquina de seus dispositivos. Em geral, os métodos de autenticação dependem de eventos únicos, como reconhecimento de íris ou face, exigindo a validação da identidade do usuário sempre que ele precisa acessar o sistema. Todavia, com a recente inclusão de biosensores em dispositivos vestíveis, alguns sinais são coletados constantemente, permitindo uma autenticação contínua. Entretanto, os métodos existentes de autenticação contínua via ECG e EMG são custosos, complexos ou inconvenientes para o usuário. Assim, para superar esses problemas, este artigo propõe o sistema BEAT, o qual utiliza biosinais do fotopletismograma (do inglês, photoplethysmogram-PPG) para estimar mudanças volumétricas no fluxo sanguíneo. Além disso, o sistema BEAT transmite os sinais coletados pela pele (i.e., comunicação por acoplamento galvânico), sendo o tecido epitelial um canal secundário seguro contra ataques baseados em radiofrequência. Os resultados de avaliações experimentais demonstram a viabilidade e eficiência do sistema.

Authors: KİRMİZİ Serdar , UCAR Bercıs İmge , YİLMAZ Sevda , AYDOGAN KİRMİZİ Demet
Published: September 2019

Endometrial stromal sarcomas (ESS) are rare mesenchymal tumors of the uterus. Low-grade endometrial stromal sarcoma (LGESS) constitutes approximately two-thirds of ESS. Metastasis of LGESS can be seen after many years. In the endoscopic examination, a 57-year-old female patient with dyspeptic complaints was diagnosed with mesenchymal originated tumor located in the antrum of the stomach.  It is reported that the patient underwent a hysterectomy and unilateral oophorectomy 15 years ago due to vaginal bleeding. A mass in the stomach approximately 5 cm in diameter was detected in the abdominal contrast-enhanced computed tomography.  She underwent subtotal gastrectomy and omentectomy, and immunohistological examination was reported as LGESS. As far as we know, it is the first case reported as a LGESS metastasis to stomach so far. We should bear in mind that metastasis of LGESS may be seen after many years.  It should be included in differential diagnosis of gastrointestinal stromal tumors

Authors: SEZGİN Muhammed , AYDIN Merve , KARAKEÇİLİ Faruk , ÇIKMAN Aytekin , Gülhan Barış , ARSLAN Yusuf Kemal
Published: September 2019

Amaç: Asimetrik dimetilarginin (ADMA), nitrik oksit sentazın (NOS) ana endojen inhibitörüdür. NOS, konak savunmasında ve vasküler yapının sürdürülmesinde önemli rol oynamaktadır. Yüksek ADMA düzeylerinin endoteldis fonksiyonu ile ilişkili olduğu ve çeşitli hastalıklarda rol aldığı gösterilmiştir. Brucellaspp.’nin neden olduğu zoonoz bir hastalık olan bruselloz, vaskülopati olarak kendini gösterebilmektedir. Ancak, bruselloz ile ADMA arasındaki ilişki ile ilgili yeterli veri bulunmamaktadır. Çalışmamızın amacı bruselloz hastalarında ve kontrol grubunda ADMA düzeyinin araştırılmasıdır.Yöntemler: Çalışmamıza 40 akut bruselloz hastası ve 40 sağlıklı gönüllü alındı. Bruselloz hastalarında ve sağlıklı gönüllülerde serum ADMA düzeyleri İnsan ADMA ELISA kiti ile üretici firma önerileri doğrultusunda araştırıldı. Katılımcıların fiziki muayeneleri yapılarak, cinsiyet, yaş ve ikamet adreslerini içeren demografik karakteristikleri ve laboratuvar test sonuçları kayıt altına alındı. Verilerin değerlendirilmesinde IBM SPSS 20 istatistik paket programı kullanıldı. İstatistiksel anlamlılık düzeyi (p<0.05) ve (p<0.01) olarak kabul edildi.Bulgular: Çalışmaya alınan 40 akut brusellozlu hastanın 18'i (% 45) erkek, 22'si (% 55) kadındı ve yaş ortalaması 49.22 ± 17.33 idi. Kontrol grubundaki 40 sağlıklı gönüllünün 18'i (% 45) erkek, 22'si (% 55) kadındı ve yaş ortalaması 39.02 ± 7.88 idi. Serum ADMA düzeyleri bruselloz ve kontrol grubunda sırasıyla; 262.6±139.59 ng/ml ve 196.52±85.25 ng/ml olarak saptandı. Bruselloz grubunda, kontrol grubu ile karşılaştırıldığında istatistiksel olarak anlamlı bir farklılık tespit edildi (p=0.013).Sonuç: Çalışmamızda bruselloz grubundaki hastalarda serum ADMA düzeyleri, kontrol grubuna göre anlamlı olarak yüksek bulundu. ADMA düzeylerindeki bu yüksekliğin, brusellozun vaskülitteki rolü konusunda yeni yorumlar yapılmasına olanak sağlanacağı ve yeni tedavi yöntemlerinin gündeme gelebileceği kanaatindeyiz.
Pektus Bar’lı Olguların Serum ve İdrar Örneklerinde Eser Elementlerin Değerlendirilmesi
Authors: AKKUŞ Murat
Published: September 2019

Amaç: Göğüs deformitelerinin metal alaşımlı barlar vasıtasıyla rekonstrüksiyon yönteminin kullanılması, metal barlara bağlı eser elementlerin vücuda yayılmasına da sebep olabilmektedir. Bu çalışma, pektus bar kullanılan sınırlı sayıda olguda serum ve idrarlarında bar alaşımı olan Demir(Fe), Nikel(Ni) ve Krom(Cr) seviyeleri analiz edilmiş ve literatürle karşılaştırılarak bir ön çalışma olarak sunulması amaçlanmıştır.Yöntemler: Daha önce bar takılmış11 Erkek (E) ve 3 Kadın (K) toplam 14 olgunun ortalama bar kalış süresi 39,70 (7-60) ay sonunda alınan serum ve idrarlarında Fe, Ni ve Cr seviyeleri çözündürülerek indüktif plazma kütle spektrofotometresi (ICP-MS) cihazı ile değerlendirildi. Sonuçlar literatür ile karşılaştırıldı.Bulgular: Serum Fe ve Ni seviyeleri normal değerler arasında saptanırken serum Cr seviyesi normal değerlerden yüksek saptanmıştır. İdrar da ise Fe ve Cr atılımı normalin çok üstünde bulunurken Ni idrarda normal seviyede saptanmıştır.Sonuç: İdrar Fe atılımı arttırılarak serum Fe seviyesinin normal tutulması sağlanabilmiş, ancak idrar Cr atılımı artmasına rağmen serum Cr seviyesi yüksek saptanmıştır. Bu da yüksek Cr serum seviyesinin vücutta birikici etki oluşturabileceği şeklinde yorumlanmıştır.
Klinik Örneklerden İzole Edilen Aspergillus Türlerinin Tanımlanmasında Geleneksel Yöntemler, MALDI-TOF MS ve Dizi Analizi Yöntemlerinin Karşılaştırılması
Authors: BİLGİ Esma Akkoyun , KİRAZ Nuri
Published: September 2019

Amaç: Aspergillus türü mantar enfeksiyonları immün sistemi baskılanmış hastalarda, yüksek mortalite ve morbidite ile sonuçlanan invazif hastalıklara yol açmaktadır. Bu nedenle hızlı ve doğru tanı konularak uygun antifungal tedavi başlanması invazif aspergillozlu hastalar için hayati öneme sahiptir. Günümüzde daha hızlı, kolay uygulanabilir, yüksek duyarlılık ve özgüllüğe sahip yeni tanı yöntemleri tercih edilmektedir. Bu çalışmada çeşitli klinik örneklerden izole edilen Aspergillus türlerinin; geleneksel yöntemler, MALDI-TOF MS sistemi ve DNA dizi analizi yöntemi kullanılarak tanımlanması ve bu yöntemlerin karşılaştırılması amaçlanmıştır.Yöntemler: Bu çalışmada çeşitli klinik örneklerden izole edilen toplam 50 Aspergillus izolatı çalışmaya dahil edildi. Aspergillus suşlarından 2 tanesi kontaminasyondan dolayı çalışma dışı bırakıldı.Bulgular: Çalışmamızda referans tanımlama yöntemi olarak kullandığımız ITS bölgesinin dizi analiziyle, suşların 25 tanesi A.fumigatus tür kompleksi (%52,08), 17’si A.flavus tür kompleksi (%35,42), 3’ü A.niger tür kompleksi (%6,25), 2’si A.terreus tür kompleksi (%4,17), 1’i A.sydowii tür kompleksi (%2,08) olarak tanımlandı. Altın standart yöntemin dizi analizi olduğu ve geleneksel yöntem ile karşılaştırıldığında %97,9 uyum olduğu gözlendi. İki farklı yazılım kullandığımız MALDI-TOF MS sisteminde ise güncel IVD (invitro diagnostik) VITEK MS V.2.0 yazılımı ile doğru tanımlanan köken 37(%77,1) iken SARAMIS 4.12 RUO yazılımı ile doğru tanımlanan köken 42(%87,5) olarak bulundu.Sonuç: Moleküler yöntemler, geleneksel yöntemlerin yetersiz kaldığı ve tür tanımının yapılamadığı durumlarda tamamlayıcı yöntem olarak kullanılabilir. Zaman açısından değerlendirildiğinde MALDI-TOF yöntemi hızlı ve duyarlı bir yöntem olmasına rağmen veri tabanının geliştirilmesi amacıyla suş sayısının arttırılarak bu tür çalışmaların tekrarlanması gerekir.

ilgili adli davalar gün geçtikçe artmakta, çocuk psikiyatristleri ve adli tıp

hekimleri adli ve mesleki anlamda daha çok bilgi ve tecrübe gereksinimi

duymaktadır. Erkek çocuk ve ergenlerde, saldırgan davranışlar ve suça

sürüklenmenin daha sık olduğu farklı çalışmalarda gösterilmiştir. Çalışmamızın

amacı; adli makamlarca Türk Ceza Kanunu (TCK) 31 ve 32 maddeleri gereğince

çocuk psikiyatrisi polikliniğine getirilen çocukların psikiyatrik muayenelerini

yaparak tanı, sosyodemografik veriler, suçun niteliği ve suça iten riskleri

belirlemektir. Ek olarak hazırlanan raporların incelenmesi de amaçlanmaktadır.

Yöntemler: Araştırma, hastanemiz etik kurulundan onay

alındıktan sonra, Haziran 2017- Kasım 2018 tarihleri arasında Çocuk

psikiyatrisi polikliniğine adli psikiyatrik muayene amacıyla getirilen,

işlendiği iddia edilen suçun hukuki anlam ve sonuçlarını algılama ve davranışlarını

yönlendirme yeteneğinin gelişip gelişmediği veya akıl hastalığı sorulan suça

sürüklenen 107 çocuğun geriye dönük dosyaları incelenerek düzenlenmiştir.

Bulgular: Çalışmaya alınan çocuklarda erkek cinsiyet, okulu bırakma oranları,

madde kullanımı, dikkat eksikliği ve hiperaktivite bozukluğu (DEHB), davranış

bozukluğu varlığının ve sosyoekonomik düzeyin düşüklüğününyüksek olduğu tespit

Ateliê como prática de liberdade
Authors:   Universidade Federal do Rio Grande do Sul, Zordan Paola Basso Menna Barreto Gomes
Published: September 2019

Ateliê, conceito intrínseco às artes visuais, é tratado em suas implicações históricas, epistemológicas e econômicas. Desde sua etimologia é pensado em suas variações terminológicas entre oficina, estúdio e laboratório. Com a ética de Michel Foucault, a heterotopia de um ateliê permite viver um só lugar em muitos espaços.
A mediação cultural em meio a controvérsias
Authors:   Universidade de Brasília, Honorato Cayo
Published: September 2019

Desde o caso Queermuseu, a expectativa de que a tarefa dos programas educativos fosse corrigir a “incompreensão do público” relativamente à arte moderna ou contemporânea foi significativamente questionada. Ocorre que diferentes públicos, baseando-se em valores quase sempre alheios aos pressupostos e debates do mundo da arte, têm se manifestado contrariamente à realização de determinadas exposições e trabalhos de arte, com uma veemência e repercussão inauditas. Qual deve ser então o papel da mediação diante dessas rejeições? Neste artigo, recorremos à metodologia proposta por Nathalie Heinich (2010) para uma sociologia dos valores, qual seja, a de “um bom uso da neutralidade”, para propor uma reformulação das atribuições e maneiras de fazer da mediação cultural no âmbito da educação em exposições de arte e espaços museais; uma que leve em conta seus aspectos investigativo, documentário, pós-crítico e propriamente político.
A abstração em movimento: abertura nos móbiles de Alexander Calder e pinturas transatlânticas de Piet Mondrian
Authors:   Universidade Estadual de Campinas, Visnadi Débora
Published: September 2019

Este artigo evidencia uma relação comparativa entre a obra de dois artistas na vanguarda da produção abstrata: Piet Mondrian na pintura e Alexander Calder na escultura. Nos diversos estudos sobre o desenvolvimento do trabalho de Calder, o papel de Mondrian encontra-se restrito à recepção do artista em seu ateliê em 1930: ao se deparar com os retângulos coloridos Calder sugeriu movimento a tudo aquilo, culminando numa série de experimentações abstratas que rapidamente se transformariam em seus conhecidos Móbiles. A divergência teórica entre eles – de um lado a rigidez de Mondrian em seguir as proposições neoplásticas, e de outro a soltura presente em Calder – não são suficientes para anular suas similaridades estilísticas. Assim, enfatizam-se os modos como suas produções se aproximam para além do despertar de Calder à abstração, apoiando-se no conceito de obra aberta de Umberto Eco para evidenciar o modo como seu incomum gênio, ao mesmo tempo apolíneo e dionisíaco, potencializa sua obra.
Existir como Arte: a que se destina?
Authors:   Instituto Federal do Rio Grande do Sul, Karwatzki Walter , Blauth Lurdi ,   Universidade Feevale
Published: September 2019

O artigo apresenta um recorte da obra do artista visual e fotógrafo Walter Karwatzki. Nele são evidenciados três trabalhos com a técnica da fotografia que têm como plataforma o corpo do artista. As obras ressaltam a passagem do fotógrafo que via apenas o outro para o fotógrafo que agora se vê e se mostra para o outro, mudança que se dá em função de uma situação de morte pela qual passou. As obras apresentadas são dotadas de uma dramaturgia resultante ora de aspectos sociais, ora de aspectos culturais ou de aspectos pessoais do artista. Nessas obras, o corpo está carregado de um grande sentido autorreferencial. Este artigo apresenta a trajetória fotográfica do autor em oito trabalhos fotográficos que, de uma maneira ou de outra, têm sua produção poética em constante aproximação com a questão da memória, tendo como referências Samain (2012), Achutti (1997, 2004), Didi-Huberman (2010), Dubois (1993), Bossi (2010), Canclini (2013) e Tolstói (2016), entre outros.
O encontro como estratégia de estar-junto da Arte Contemporânea
Authors:   Universidade do Estado do Rio de Janeiro, Almeida Bruno Gomes de
Published: September 2019

A tentativa de parte da produção artística contemporânea de promover diferentes tipos de agencimentos coletivos pode ser pensada como indício de um desejo genuíno de estar junto, estratégia para fazer insurgir um “nós” mais singular. Desta forma, o presente texto, como parte de um estudo mais amplo acerca das formas de estar-junto da arte contemporânea, pretende se debruçar sobre uma forma específica que se evidencia em vários trabalhos artísticos. É o estar-junto dos “encontros”. O propósito é aprofundar um olhar a respeito dessa estratégia relacional, identificando toda a potência por trás de trabalhos que lançam mão dos encontros enquanto verdadeiros dispositivos instauradores de formas de estar-junto. Para isso, foram analisados trabalhos específicos de Marina Abramovic, coletivo OPAVIVARÁ!, Ana Teixeira, Eleonora Fabião e Anna Costa e Silva.
Talvez seja mentira: estudos sobre narrativas fotográficas ficcionais na Arte Contemporânea
Authors:   Universidade de Brasília, Melo Havane Maria Bezerra de
Published: September 2019

Essa pesquisa visa esclarecer o significado da fotografia cinematográfica contemporânea, localizando-a no espaço-tempo social, baseada nos textos de autores como Charlotte Cotton, Vilém Flusser e outros emprestados de diversas áreas do conhecimento como a comunicação, a literatura e a antropologia, porém, preocupados em tratar da narrativa ficcional e da interpretação simbólica. As ideias são sustentadas principalmente sobre o tripé: ficção, narrativa e interpretação, destacando a construção identitária, a participação do modelo e do público na interpretação de um trabalho e outros recursos característicos da narrativa visual que podem ser utilizados pelo autor como forma de aproximação com o receptor. Ao longo do texto, apontamos algumas obras, sobre as quais tecemos considerações a cerca da narrativa e processo de criação, a fim de exemplificar os conceitos discutidos. Como resultado da pesquisa, inserimos alguns trabalhos autorais, desenvolvidos sob o manto dos conceitos discutidos.
Effect of Dietary Supplementation of Rumen Undegradable Protein on Productive Performance of Early Lactating Buffaloes
Authors: Tiwari Shyam Krishna , Shah Ramashish , Nepali Dainik Bahadur , Tariq Muhammad , Acharya Krishna Prasad
Published: September 2019

An experiment was conducted to study the effect of dietary supplementation of rumen un-degradable protein on productive performance of early lactating buffaloes for the duration of 90 days from February 5, 2014, to May 5, 2014. A total of twenty one lactating Murrah buffaloes in their early to mid-lactation were randomly selected and divided into three groups. Experimental diets were formulated into three- low (30.56% of dietary Crude Protein), medium (43.54% of dietary crude protein) and high (50.04% of dietary CP), iso-nitrogenous (16% CP) and iso-caloric (72% total digestible nutrients) rumen un-digestible protein (RUP) levels. A significant difference (p<0.05) in body weight gain of buffaloes was recorded in animals of high RUP group in comparison to medium and low RUP groups. Milk yield in the medium RUP group (43.54%) was significantly higher than the high and the low RUP group (p<0.05). The mean serum total protein, blood urea nitrogen concentrations were significantly lower in both the high and the medium RUP groups than in the low RUP group (p<0.05). However, blood glucose level was significantly higher in high RUP group than in low and medium RUP group (p<0.05) whereas milk fat, solid not fat, lactose, protein and electrical conductivity showed no significant differences among the three treatment groups (p>0.05). Hence, it can be concluded that the diet containing a medium level of dietary CP as RUP improved the productive performance of early lactating buffaloes. Thus, diet containing the medium level of dietary CP as RUP should be given to improve the productive performance of early lactating buffaloes under the climatic settings of Nepal.

Purpose: to define the dynamics of physical development indicators among medical college students in 2017 and to compare it with the results of the previous study of 2005.
Method: The inclusion criteria were: no health complaints at the time of the examination, no chronic diseases in family medical history, no deviations from the norm in clinical and laboratory tests. The selected young men were examined by medical specialists (neuropathologist, ophthalmologist, otolaryngologist, therapist, surgeon); detailed clinical, laboratory and diagnostic tests were conducted: X-ray; spirography; electrocardiography; dental examination; ultrasound examination (cardiovascular, thyroid, abdominal, urological); biochemical blood testing. The participants were subdivided into two groups: Group 1 (students (n=140) who studied at Zhytomyr Medical College in 2004-2005) and Group 2 (students (n=150) who studied at Zhytomyr Medical Institute in 2016-2017).
Results: According to the results of studying the dynamics of anthropometric, functional and psychophysiological indicators of physical development among Ukrainian medical college students (n=290; 17-21 years old) in 2017, comparing them with the results of the previous study, conducted in 2005, the tendency to gain in body mass in average values from (0.88 ± 0.26) to (2.7 ± 0.67), in body mass index from (0.88 ± 0.26) to (1.38 ± 0.38), in the fat component from (8.70 ± 0.22) to (9.36 ± 0.21) was established.
Conclusions: An increase in body mass index, the fat component in medical college students was revealed, which is related to problems in the quality of the students' diet. Though the muscle mass has increased, and the study indicates that there is insufficient physical activity; sustainability and concentration of attention indicators tend to decrease under the influence of intensification of the educational process. The dynamics of the indicators under analysis indicates the stabilization of the growth process in Ukrainian male students.
Imaging in pregnancy-associated breast cancer: a case report
Authors: Untanas Audrius , Grigaitė Indrė , Briedienė Rūta
Published: September 2019

Background. PABC (pregnancy-associated breast cancer) is a rare condition that appears as a malignancy in 1 per 3000 pregnant women and is one of the most common cancers diagnosed during pregnancy or the postpartum period. If a woman who is pregnant or within a year after delivery has complaints of a palpable breast mass, it could undeniably be a malignant mass of the breast. That is why an ultrasound should be performed for all pregnant or lactating women who detect a palpable breast mass that persists for two or more weeks.
Case report. Our case report presents a pregnant 40-year-old previously healthy female at 36 weeks gestational age with a complaint of a palpable left breast mass for two months period. The initial ultrasound showed a breast tumour of irregular shape, solid and hypervascular mass.
Conclusions. Early diagnostics of PABC is of crucial importance in order to offer the best possible outcomes for the patient and foetus.
Dolor social, conflictividad y pobreza: un abordaje desde las experiencias de inmigrantes limítrofes en la Ciudad de Buenos Aires
Authors: D'hers Victoria , Cervio Ana Lucía
Published: September 2019

Los modos en que la conflictividad surca y configura las formas de habitar en contextos de extrema privación es una problemática que tensiona las maneras en que cuerpos y emociones son atravesados por distintos registros del dolor social. Las diversas formas y contenidos que asume el sufrimiento en sus conexiones con la pobreza urbana también aparecen dialectizadas con “prácticas intersticiales” que desafían a la resignación y la impotencia como lógicas de aceptación y visibilización del mundo. Desde una sociología de los cuerpos/emociones este artículo se propone abordar el dolor como emoción, y al conflicto como práctica y condición de reproducción social, tomando como referente empírico entrevistas en profundidad efectuadas en 2015 y 2016 a inmigrantes limítrofes que residen en distintas villas de emergencia de la Ciudad de Buenos Aires. Concretamente, se indagan los vínculos entre sensibilidades, conflictividades y políticas sociales desde las experiencias de los sujetos, profundizando en algunas tensiones/conexiones identificadas entre dolor y “prácticas intersticiales” asociadas con la pobreza, la informalidad urbana y las políticas sociales.
España, frontera de color. El racismo como síntoma del fracaso necesario de la identidad nacional
Authors: Gil Hernández Roberto
Published: September 2019

Al contrario de lo que suele pensarse, la raza no es la matriz en que se gesta el racismo, sino que es el racismo el que inventa la raza, su condición de posibilidad. Solo así puede entenderse la manera en que este fenómeno ha apelado a distintos órdenes de nuestra realidad para generar el conjunto de normas, ideas y emociones que constantemente nos atraviesan como sociedad. En este artículo se intentará evaluar la incidencia del racismo en España, analizando el impacto reciente de la inmigración ilegal en sus redes sociales y medios de comunicación. Partiendo del reconocimiento del papel que ha jugado la colonialidad a lo largo de su historia, así como de la perturbadora necesidad que esta ha impuesto para excluir a su otredad racializada, se tratará de demostrar el papel que ha jugado el país como frontera de color, como límite que separa a las poblaciones del continente africano y europeo. El objetivo es señalar, por medio de la teoría psicoanalítica, el carácter contingente del racismo como mecanismo adscrito a su identidad nacional, además de constatar su fracaso como afluente y como límite de su condición simbólica y libidinal.
Grounding social criticism: from understanding to suffering and back
Authors: Hirvonen Onni
Published: September 2019

This paper critically examines John Dewey’s and Axel Honneth’s critical social philosophies in order to highlight two different normative sources of social struggle: scientific understanding and social suffering. The paper discusses the relations of these sources with each other and aims to show to what extent the normative sources of Dewey’s and Honneth’s critical social theories are compatible. The comparison between Dewey and Honneth is used in order to argue for a desiderata for critical social ontology. The argument is that we want to consistently include both elements – suffering and understanding – in a critical theory as only by having both will critical theory grant a clear enough direction and good enough motivational normative core for a social struggle.
La educación sentimental del siglo XXI. Mitos y emociones de la saga Crepúsculo
Authors: González Isaac
Published: September 2019

En este artículo profundizo en algunos de los elementos clave de la educación sentimental –o de la educación emocional, en un sentido más amplio– que se transmite en un conjunto de películas que obtuvieron un gran éxito de audiencia entre el público joven y adolescente hace unos años: la saga Crepúsculo. La tesis que aquí defiendo es que, a nivel mitológico, dicha saga filmográfica (así como las novelas homónimas, que no se analizan en el presente artículo) reproducen un principio clave del tejido mitológico de la contemporaneidad relativo al papel de las emociones en la estructuración de la sociedad (Illouz, 1997).
The Conference Reimagined. Postcards, Letters, and Camping Together in Undressed Places
Authors: Veijola Soile , Höckert Emily , Carlin David , Light Ann , Säynäjäkangas Janne
Published: September 2019

In this paper, five authors account for the rethinking of a conference as a series of postcards, letters, rules and silent moments so that traditional hierarchies of knowledge could be overturned or, at least, sidelined. We recount how the place we convened was enlisted as an actor and the dramas and devices we applied to encounter it. We use this accounting to problematize the conventional practices of goal-oriented meetings and co-authored papers as forms of academic meaning-making. In finding a meeting point where expertise was disorientated and status undressed, we were able to investigate the idea of co-being between human and nonhuman realities as the step social theory needs to take to become a point of connection with the social world, instead of an escape from it. We conclude that this involved silence and necessary fictions as a means to consider the future and past in the moment of meeting.
Pyoderma Gangrenosum–Like Lesion in an Older Adult
Authors: Swindell William R. , Gau Jen-Tzer
Published: September 2019

Pyoderma gangrenosum (PG) is a rare but serious neutrophilic dermatosis characterized by ulcerative lesions with violaceous borders. The disease mainly occurs in young or middle-aged adults. The authors present the case of a 79-year-old female nursing home patient who had an idiopathic PG-like ulcer on her lower extremity. Initial treatment with 3 courses of antibiotics and topical wound care for assumed cellulitis failed to improve the lesion, but the ulcer healed rapidly after a 1-week course of prednisone therapy (15 mg/d). This case provides insights into the challenges that arise in the diagnosis and management of PG in an older patient with extensive comorbidities. It also highlights the importance of considering PG as a diagnosis for older patients with a distinctive inflammatory ulcer that does not respond to antibiotics and topical wound care, since timely treatment with low-dose steroids can lead to quick healing by aborting the underlying autoinflammatory process.

The North Atlantic Sightings Survey (NASS), the sixth in a series of surveys conducted between 1987 and 2015, was conducted in June/July 2015 and covered a large area of the northern North Atlantic. The Icelandic and Faroese ship survey component of the NASS covered the area between the Faroe Islands and East Greenland from latitude 52° to 72° N. The survey used 3 vessels and an independent double-platform configuration with each platform staffed by a minimum of 2 observers. Here we present both uncorrected abundance estimates derived using Multiple Covariates Distance Sampling, and corrected abundance estimates derived using Mark-Recapture Distance Sampling, for the following species: fin (Balaenoptera physalus), common minke (B. acutorstrata), humpback (Megaptera novaeangliae), blue (B. musculus), sei (B. borealis), sperm (Physeter macrocephalus), long-finned pilot (Globicephala melas) and northern bottlenose (Hyperoodon ampullatus) whales as well as white-beaked (Lagenorhynchus albirostris) and white-sided (L. acutus) dolphins. We then compare these estimates to those from previous NASS and put them into context with estimates from adjoining areas of the North Atlantic.

The organic carbon mineralization process reflects the release intensity of soil CO2. Therefore, the study of organic carbon mineralization and particle composition analysis of soft rock and sand compound soil can provide technical support and a theoretical basis for soil organic reconstruction (soil structure, materials and biological nutrition). Based on previous research, four treatments were selected: CK (soft rock:sand=0:1), C1 (soft rock:sand=1:5), C2 (soft rock:sand=1:2) and C3 (soft rock:sand=1:1), respectively. Specifically, we analyzed the organic carbon mineralization process and soil particle composition by lye absorption, laser granulometer, and scanning electron microscope. The results showed that there was no significant difference in organic carbon content between C1, C2 , and C3 treatments, but they were significantly higher than in the CK treatment (P < 0.05). The organic carbon mineralization rate in each treatment accords with a logarithmic function throughout the incubation period (P < 0.01), which can be divided into a rapid decline phase in days 1 to 11 followed by a steady decline phase in days 11 to 30. The cumulative mineralization on the 11th day reached 54.96%–74.44% of the total mineralization amount. At the end of the incubation, the cumulative mineralization and potential mineralizable organic carbon content of the C1, C2 and C3 treatments were significantly higher than those of the CK treatment. The cumulative mineralization rate was also the lowest in the C1 and C2 treatment. The turnover rate constant of soil organic carbon in each treatment was significantly lower than that of the CK treatment, and the residence time increased. With the increase of volume fraction of soft rock, the content of silt and clay particles increased gradually, the texture of soil changed from sandy soil to sandy loam, loam , and silty loam, respectively. With the increase of small particles, the structure of soil appear ed to collapse when the volume ratio of soft rock was 50%. A comprehensive mineralization index and scanning electron microscopy analysis, when the ratio of soft rock to sand volume was 1:5–1:2, this can effectively increase the accumulation of soil organic carbon. Then, the distribution of soil particles was more uniform, the soil structure was stable (not collapsed), and the mineralization level of unit organic carbon was lower. Our research results have practical significance for the large area popularization of soft rock and sand compound technology.
Prediction model for patients with acute respiratory distress syndrome: use of a genetic algorithm to develop a neural network model
Authors: Zhang Zhongheng
Published: September 2019

Background

Acute respiratory distress syndrome (ARDS) is associated with significantly increased risk of death, and early risk stratification may help to choose the appropriate treatment. The study aimed to develop a neural network model by using a genetic algorithm (GA) for the prediction of mortality in patients with ARDS.

Methods

This was a secondary analysis of two multicenter randomized controlled trials conducted in forty-four hospitals that are members of the National Heart, Lung, and Blood Institute, founded to create an acute respiratory distress syndrome Clinical Trials Network. Model training and validation were performed using the SAILS and OMEGA studies, respectively. A GA was employed to screen variables in order to predict 90-day mortality, and a neural network model was trained for the prediction. This machine learning model was compared to the logistic regression model and APACHE III score in the validation cohort.

Results

A total number of 1,071 ARDS patients were included for analysis. The GA search identified seven important variables, which were age, AIDS, leukemia, metastatic tumor, hepatic failure, lowest albumin, and FiO2. A representative neural network model was constructed using the forward selection procedure. The area under the curve (AUC) of the neural network model evaluated with the validation cohort was 0.821 (95% CI [0.753–0.888]), which was greater than the APACHE III score (0.665; 95% CI [0.590–0.739]; p = 0.002 by Delong’s test) and logistic regression model, albeit not statistically significant (0.743; 95% CI [0.669–0.817], p = 0.130 by Delong’s test).

Conclusions

The study developed a neural network model using a GA, which outperformed conventional scoring systems for the prediction of mortality in ARDS patients.

Yam, like most roots and tubers, has a tissue variation that is responsible for the difference in cooking observed during culinary preparations. In order to understand the origin of this variation, this study was conducted through optical microscope and SEM observation of the beginning of tuberization. The local variety named Kponan of Dioscorea cayenensis-rotundata was used. The days after the beginning of the tuberization, the protrusion of the stem base intensified and gives rise to the tuber. The histological study of the onset of tuberization revealed once again the existence of a longitudinal growth gradient whose point of growth is the apex and the sense of maturity of the distal part at the proximal end. The cells birth at the apex and differ a little more towards the middle part of the tuber. The apex is the driving zone for the tuber's lengthwise growth. The cambial cells ensure this growth in length and thickness of the tuber. The tuber's growth activity decreases from the distal part to the proximal one. The distal part contains more vacuolated cells thus rich in water and less starch than the middle and proximal parts. The cell wall is thin and less lignified. The cambium generates cells at the lower end of the apex. These very vacuolated cells differentiate and will form the median and proximal parts of the tuber. The distal part will remain immature compared to the other two parts. This could explain the low dry matter and the origin of rejection or elimination of the distal part during culinary operations.

Published: September 2019

India is predominantly a food crop producing country in the world and a leading producer of world’s pulse (25.00%), rice (22.00%), wheat (13.00%) and cotton (25.00%). On the other hand, the country has gone through a substantial shift in cropping pattern from food crops (agricultural crops) to horticultural crops over the last five years (2011-15). The state Tamil Nadu has also witnessed a shift in cropping pattern towards horticulture. Therefore, micro-level research was undertaken in Malaipalayam and Vadavedampatti of Sultanpet block and Naickenpalayam and Nanjundapuram of Periyanaickenpalayam block in Coimbatore district, Tamil Nadu, India. The sample size of the study was 120 farmers. The research found that most (23.50%) of the farmers shifted their cropping pattern to horticulture during the year 2005-06 followed by 11.50 per cent during 2002-03. However, the shift in cropping pattern towards horticulture started during the 21st century.

It was observed from the study nearly one-fifth (20.84%) of the farmers chosen Coconut as the sole crop in the place of Pulses (Field bean/Cowpea/Horse gram + Field bean-Mochai) – Maize/ Sorghum + Sugarcane + Fodder crops during 2016-17. Twenty-two farmers cultivated Coconut + Vegetables during 2016-17 yet, these same farmers had the cropping pattern of Sugarcane/Maize/ Sorghum + Pulses (Horse gram + Bengal Gram/Cowpea/Red gram/Green gram/Field bean)/Cotton/ Paddy during 1999-2000.

The area under horticulture increased to more than three-fifths (67.35%) of the total area among the farmers during 2009-10 (After Shift). However, the area (4.50%) of horticulture was very less during 1999-2000 (Before Shift) when compared to the area (87.99%) of agriculture to the total area. In this context, this paper elucidates the nature of the shift in cropping pattern from agriculture to horticulture and the present status/ trend of horticulture in Coimbatore district and future prospectus.

Aim: The aim of the study was to carry out a comparative analysis of the proximate, vitamin and mineral composition of the leaves of four selected tropical vegetable plants namely: Ocimum gratissimum, Piper guineense, Gongronema latifolium and Vernonia amygdalina.

Methodology: Fresh leaves of each vegetable were washed and air dried at room temperature for two weeks. The dried leaves were pulverized using a mechanical grinder. Measured amounts were subjected to quantitative proximate, vitamin and mineral analysis.

Results: For all four plants, carbohydrates was the major macronutrient constituents (range 49.61-64.09% dry wt.) followed by fats (15.06-29.43%), Protein (7.28-12.53%), ash (1.81-14.82%) and fiber (2.92-7.53%) in that order. G. latifolium had the highest carbohydrate (64.09±0.09% dry weight) and protein (12.53±0.10%) composition while V. amygdalina had the highest fat (29.43±0.03%) composition. Results of Ash analysis of the four leaves showed P. guineense to have the highest total mineral content (14.82±0.12% dry wt.) followed by V. amygdalina (10.75±0.01%), O. gratissimum (4.60±0.04%) and G. latifolium (1.81±0.01%) in that order. O. gratissimum and P. guineense had the highest composition of fiber (7.53±0.02% and 7.22±0.02% respectively) closely followed by G. latifolium (6.03±0.02%) and V. amygdalina (2.92±0.02%). Vitamin analysis revealed that leaves of the four vegetable plants contained high levels of vitamin C (range 18.1-43.4 mg/100 g) and appreciable quantities of vitamins A (0.3-1.2 mg/100 g) and E (0.67-0.9 mg/100 g). V. amygdalina leaf contained the highest concentration of vitamin C (43.4±0.01 mg/100 g) and A (1.2±0.9 mg/100 g) while O. gratissimum had the highest vitamin E content (0.9 mg/100 g). The mineral assay indicated that the leaves of the plants contain high levels of Magnesium (Mg)(3.6-24.8 mg/100 g), Phosphorus (P) (2.8-34.3 mg/100 g), Calcium (Ca) (12.1-19.0 mg/100 g) and copper (Cu) (5.8-18.5 mg/100 g) relative to their Zinc (Zn) (1.1-2.1 mg/100 g), Potassium (K) (2.1-6.9 mg/100 g)  and Sodium (Na) (4.3-8.1 mg/100 g) contents.

Conclusion: In conclusion, these plants were shown to be rich in carbohydrates, proteins and fats, vitamins and minerals justifying their use in diets. That the plants were particularly rich in vitamins and mineral with antioxidant properties could explain the therapeutic uses of the various preparations of these leafy vegetables, in traditional medicine, for the treatment and management of diseases that have their etiology and pathophysiology in free radical generation and oxidative stress.
