Supramolecular Materials for Optical and Electrochemical Biosensors

It is incontestable that the interactions and bonds that keep molecules united to generate unique supramolecular compounds, with individual properties, morphologies and behaviour, are of special dynamics and singular forces. Therefore, it is necessary to discuss and consider the types of interactions that may occur in a determined system, their dynamics and number, which directly act on the energetic balance that strengthen the union between participants and give rise to a supramolecule

Factors Associated with Emotion Regulation in Men with Internet Access Living in Brazil during the COVID-19 Pandemic

Publisher Copyright: © 2022 by the authors. Licensee MDPI, Basel, Switzerland.Objective: to evaluate the factors associated with emotion regulation in men with internet access living in Brazil during the COVID-19 pandemic. Method: an epidemiological survey, conducted with 1015 men. An electronic form was applied containing sociodemographic and occu-pational characteristics, support and coping strategies, as well as emotional and behavioral aspects. Emotion regulation was assessed using the Emotion Regulation Questionnaire. Results: The prevalence values observed were 44.6% for Low Cognitive Reappraisal and of 47.1% for High Emotional Sup-pression. The following factors were identified as associated: (a) with Low Cognitive Reappraisal: being aged 30 years old or more, practicing physical activity, worrying about social distancing and having positive emotions and feelings; and (b) with High Emotional Suppression: being heterosexual, non-white race/skin color, having security support or public administration, not sanitizing food, worrying about lack of physical activity and not having negative emotions. Conclusion: the adoption of emotion regulation strategies was associated with individual, contextual and emotional/behavioral characteristics. Masculinity ideals seem to exert an influence on these relationships.publishersversionpublishe

Sarcoma ósseo secundário da Doença de Paget: Secondary bone sarcoma of Paget's disease

Resumo INTRODUÇÃO: A Doença de Paget é uma doença crônica inflamatória do osso. A degeneração sarcomatosa dessa doença é rara, chegando a 1% e o tipo histológico mais comum é o osteossarcoma. APRESENTAÇÃO DO CASO: Paciente com 66 anos, masculino, com diagnóstico de Doença de Paget há 20 anos, apresenta deformidade em fêmur direito, relata piora da dor há 5 meses. Radiografia com sinais de malignidade confirmados na RNM, na qual havia expansão das partes moles, ruptura da cortical óssea com osteólise agressiva. Histopatológico confirmando osteossarcoma. DISCUSSÃO: A Doença de Paget é um distúrbio ósseo crônico que resulta na renovação óssea acelerada e desordenada, acomete, principalmente, o esqueleto axial, o crânio, os fêmures e as tíbias. A maioria dos pacientes com Doença de Paget é assintomática, sendo o diagnóstico, muitas vezes, tardio e acidental. É a segunda doença osteometabólica mais comum, ficando atrás da osteoporose. A doença de Paget afeta cerca de 3-4% da população acima dos 40 anos de idade, sendo que sua prevalência aumenta com a idade. O osteossarcoma secundário à doença de Paget é raro, estima-se que ocorra em menos de 1% das pessoas com doença óssea de Paget. Dor, edema e fratura são manifestações iniciais. Achados radiográficos iniciais geralmente mostram uma lesão lítica em expansão no osso. O tratamento do osteossarcoma secundário à Doença de Paget é principalmente cirúrgico que pode envolver a combinação de quimioterapia. A presença de comorbidades em idosos limita o uso da quimioterapia. Quando indicada, a quimioterapia geralmente é neoadjuvante e em terapia adjuvante CONCLUSÃO: Compreende-se que a Doença de Paget acomete principalmente idosos e que o prognóstico é ruim tanto em pacientes sintomáticos como em assintomáticos, devido a inflamação óssea e risco de evolução para osteossarcoma, porém o diagnóstico precoce pode trazer benefícios aos pacientes no controle da dor e com tratamentos mais conservadores, evitando a necessidade de amputações, com melhoria na qualidade de vida

Síndrome de fraser : Fraser syndrome

Introdução: a Síndrome de Fraser é caracterizada por presença de criptoftalmo, sindactilia, anormalidades da genitália e outras malformações congênitas do nariz, ouvido ou laringe, defeitos esqueléticos, hérnia umbilical, agenesia renal e retardo mental. É uma expressão fenotípica que depende da consanguinidade dos pais. Apresentação do caso: paciente do sexo feminino, três meses de idade, em acompanhamento no centro de referência oftalmológica da Faculdade de Medicina da Universidade São Paulo. Na ultrassonografia de abdome total, foi apenas evidenciada presença de hérnia umbilical simples. Discussão: a prevalência é igual entre os sexos e a doença pode ser diagnosticada à ultrassonografia pré-natal e fetoscopia ou no momento do nascimento frente às alterações apresentadas pelo paciente, por critérios maiores e menores. O tratamento é multidisciplinar e dependente das malformações presentes, assim como o prognóstico, que é pior em casos de malformações urogenitais e laríngeas graves. Conclusão: os médicos devem estar atentos, para as manifestações clínicas e o diagnóstico preciso, oferecendo tratamento adequado e aconselhamento genético aos casais

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

ATLANTIC-CAMTRAPS: a dataset of medium and large terrestrial mammal communities in the Atlantic Forest of South America

Our understanding of mammal ecology has always been hindered by the difficulties of observing species in closed tropical forests. Camera trapping has become a major advance for monitoring terrestrial mammals in biodiversity rich ecosystems. Here we compiled one of the largest datasets of inventories of terrestrial mammal communities for the Neotropical region based on camera trapping studies. The dataset comprises 170 surveys of medium to large terrestrial mammals using camera traps conducted in 144 areas by 74 studies, covering six vegetation types of tropical and subtropical Atlantic Forest of South America (Brazil and Argentina), and present data on species composition and richness. The complete dataset comprises 53,438 independent records of 83 species of mammals, includes 10 species of marsupials, 15 rodents, 20 carnivores, eight ungulates and six armadillos. Species richness averaged 13 species (±6.07 SD) per site. Only six species occurred in more than 50% of the sites: the domestic dog Canis familiaris, crab-eating fox Cerdocyon thous, tayra Eira barbara, south American coati Nasua nasua, crab-eating raccoon Procyon cancrivorus and the nine-banded armadillo Dasypus novemcinctus. The information contained in this dataset can be used to understand macroecological patterns of biodiversity, community, and population structure, but also to evaluate the ecological consequences of fragmentation, defaunation, and trophic interactions. © 2017 by the Ecological Society of Americ
