From Robot-Assisted Intervention to New Generation of Autism Screening: an Engineering Implementation Beyond the Technical Approach

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that affects people from birth, whose symptoms are found in the early developmental period. The ASD diagnosis is usually performed through several sessions of behavioral observation, exhaustive screening, and manual coding behavior. The early detection of ASD signs in naturalistic behavioral observation may be improved through Social Assistive Robotics (SAR) and technological-based tools for an automated behavior assessment. Robot-assisted tools using Child-Robot Interaction (CRI) theories have been of interest in intervention for children with Autism Spectrum Disorder (CwASD), elucidating faster and more significant gains from the diagnosis and therapeutic intervention when compared with classical methods. Additionally, using computer vision to analyze the childs behaviors and automated video coding to summarize the responses would help clinicians to reduce the delay of ASD diagnosis. Despite the increment of researches related to SAR, achieving a plausible Robot-Assisted Diagnosis (RAD) for CwASD remains a considerable challenge to the clinical and robotics community. The work of specialists regarding ASD diagnosis is hard and labor-intensive, as the conditions manifestations are inherently heterogeneous and make the process more difficult. In addition, the aforementioned complexity may be the main reason for the slow progress in the development of SAR with diagnostic purpose. Also, there still is a lack of guidelines on how to select the appropriate robotic features, such as appearance, morphology, autonomy level, and how to design and implement the robots role in the CRI. Thus, this Ph.D. Thesis provides a comprehensive Robot-Assisted intervention for CwASD to assess autism risk factors for an autism diagnostic purpose. More specifically, two studies were conducted to analyze and validate the system performance. Through statistical data analysis, different behavior pattern of the CwASD group were identified, which suggest that these patterns can be used to detect autism risk factors through robot-based interventions. To increase the scope of this research, a theoretical conceptualization of the pervasive version of the multimodal environment was described as well as a participatory design methodology was designed and implemented on the Colombian autism community, providing, a set of guidelines regarding the design of a social robot-device suitable to be applied for robot-assisted intervention for CwASD

Creation of museums as strategy for preservation of the fossil heritage of Araripe sedimentary basin in Pernambuco, NE, Brazil

O Araripe pernambucano tem excelentes exposições de rochas da Formação Santana, Bacia Sedimentar do Araripe (PE, CE e PI), reconhecida internacionalmente pelos fósseis de vertebrados, preservados em concreções, considerados entre os mais importantes do supercontinente Gondwana (110 Ma). Embora a região tenha excelente potencial para coleta e estudos paleontológicos, facilitada pela extração a céu aberto da gipsita (Polo Gesseiro do Araripe), não existem ações de preservação do patrimônio fossilífero. Dado a vocação mineira e o potencial paleontológico, a região torna-se relevante para desenvolvimento de programas, projetos e ações que promovam os recursos naturais para uso educacional, turístico, inclusão social e sustentabilidade. Propõe-se a criação de museus paleontológicos nos municípios do Araripe pernambucano, como estratégia de uso sustentável desses recursos para geração de cultura e renda para a região, ao mesmo tempo em que se preserva para as gerações futuras a “memória paleobiológica da Terra”, retratada nos nossos fósseis.The Araripe Basin portion located in the Pernambuco state of Brazil has excellent Santana Formation outcrops. This internationally known unit has provided some of the most important concretion preserved vertebrate fossils of the Lower Cretaceous (~110 Ma) Gondwana. Although this region has its potential for fossil collecting eased by the gypsum extraction in surface mines (known as the ‘Araripe Plast Pole’), there are currently no fossil Patrimony preservation actions in the area. Given both the mining and paleontological potentials of these localities it is relevant to develop programmes, projects, and measures to promote its natural resources for educational, touristic, social, and sustainable porpuses. Here we propose the creation of paleontological museums in some of the Araripe municipalities within the Pernambuco state. These museums will be strategic for the sustainability of these resources to generate culture and profit for this region. These museums will also preserve the ‘Earth’s paleobiological memory’ by protecting our fossils for future generations.Agradecemos ao Conselho Nacional de Desenvolvimento Científico e Tecnológico do Brasil/CNPq, pela bolsa de produtividade de pesquisa 303071/2014-1 e o projeto de pesquisa 401748/2010, a Pró-reitora de Extensão- PROEXT-UFPE e a FUNCULTURA, Processo 0756/2014.

Listeria monocytogenes Inhibits Serotonin Transporter in Human Intestinal Caco-2 Ce

Listeria monocytogenes is a Gram-positive bacterium that can cause a serious infection. Intestinal microorganisms have been demonstrated to contribute to intestinal physiology not only through immunological responses but also by modulating the intestinal serotonergic system. Serotonin (5- HT) is a neuromodulator that is synthesized in the intestinal epithelium and regulates the whole intestinal physiology. The serotonin transporter (SERT), located in enterocytes, controls intestinal 5-HT availability and therefore serotonin’s effects. Infections caused by L. monocytogenes are well described as being due to the invasion of intestinal epithelial cells; however, the effect of L. monocytogenes on the intestinal epithelium remains unknown. The main aim of this work, therefore, was to study the effect of L. monocytogenes on SERT. Caco2/TC7 cell line was used as an enterocyte-like in vitro model, and SERT functional and molecular expression assays were performed. Our results demonstrate that living L. monocytogenes inhibits serotonin uptake by reducing SERT expression at the brush border membrane. However, neither inactivated L. monocytogenes nor soluble metabolites were able to affect SERT. The results also demonstrate that L. monocytogenes yields TLR2 and TLR10 transcriptional changes in intestinal epithelial cells and suggest that TLR10 is potentially involved in the inhibitory effect observed on SERT. Therefore, L. monocytogenes, through TLR10-mediated SERT inhibition, may induce increased intestinal serotonin availability and potentially contributing to intestinal physiological changes and the initiation of the inflammatory response.This work was funded by grants from the Spanish Ministry of Science and Innovation and the European Regional Development Fund (ERDF/FEDER) (BFU2010-18971), Zaragoza University (UZ2014- BIO-03), European Social Found (ESF), and the Aragon Regional Government (B61) and the Foundation for the Study of Inflammatory Bowel Diseases in Aragón (ARAINF 2012/0567).

Degradabilidade ruminal in situ do sorgo grão em diferentes formas de reconstituição.

Foram utilizadas três vacas não lactantes fistuladas no rúmen com o objetivo de determinar os parâmetros de degradação ruminal in situ da matéria seca (MS) e do amido de grãos de sorgo sob diferentes formas de processamento: 1) Seco e moído (2mm); 2) Seco, moído (3mm), reidratado com aspersão de água sobre o material, e imediatamente ensilado por 30 dias; 3) Seco, inteiro, reidratado por três dias em tubo PVC e, em seguida, moído a 5mm; 4) Seco, inteiro, reidratado por três dias em tubo PVC com aplicação de ar comprimido e, em seguida, moído a 5mm; 5) Seco, inteiro, reidratado por três dias em tubo PVC e, em seguida, moído a 5mm, e ensilado por 30 dias; 6) Seco, inteiro, reidratado por três dias em tubo PVC com aplicação de ar comprimido, moído a 5mm e ensilado por 30 dias. Os teores de proteína bruta, amido, e fibra em detergente neutro (% da MS) variaram de 9,8 a 10,8%; 59,5 a 67,5%; e de 16,1 a 19,3%, respectivamente. Os teores de umidade nos grãos que foram reidratados variaram de 35,8 a 43,9% da MS. A taxa e a extensão de degradação do amido e a degradabilidade potencial da MS foram semelhantes (P>0,05) entre tratamentos. Os grãos de sorgo reidratados com aplicação de ar comprimido, moídos e ensilados (tratamento 6) apresentaram degradabilidade efetiva (DE) da MS e DE do amido sob taxa de passagem ruminal de 2%/h, semelhantes (P>0,05) às observadas para o tratamento 5 (sem aplicação de ar comprimido), e superiores (P<0,05) às dos demais processamentos. Sob taxas de passagem no rúmen de 5 e 8%/h, as DE do amido estimadas para os grãos processados no tratamento 6 foram superiores (P<0,05) às obtidas para os demais tratamentos. O processamento de reidratação por três dias com aplicação de ar comprimido e ensilagem por trinta dias aumentou a degradabilidade efetiva da matéria seca e do amido dos grãos de sorgo, e sua utilização pode ser recomendada para animais em níveis intermediário e elevado de desempenho
