PREDAÇÃO DE Tropidurus oreadicus (REPTILIA, TROPIDURIDAE) POR Heterophrynus sp. (ARACHNIDA, PHRYNIDAE) EM UMA CAVERNA NO PARQUE NACIONAL CHAPADA DAS MESAS, MARANHÃO, BRASIL

In the area of the Chapada das Mesas National Park, south of the state of Maranhão, Brazil, the sandstone of the Sambaíba Formation (Triassic) predominate, demonstrating to be an area with potential for the occurrence of groundwater natural cavities. Cavernous ecosystems do not have vegetation cover and light (aphotic). Its trophic resources originate from external physical and biotic agents. The fieldwork found and identified 87 caves and evaluated its degree of relevance, including a biospeleological survey. During the effort, among the representatives of the cave fauna of the park, one of the most common were the amblypygids of the genus Heterophrynus, troglophiles animals, with representatives found in all the tropical and semitropical zones around the world. This group assumes a tertiary or secondary consumer role in the ecosystems where it occurs, with predation records ranging from arthropods to birds such as the hummingbirds (Aves, Trochilidae). One of the Heterophrynus records that deserves prominence, occurred in a cave which is in a region where the predominant vegetation of the surrounding area is the Cerradão. In this cavity, a trophic relationship of predation was recorded between an amblypygid from the Heterophrynus genus and a Tropidurus oreadicus lizard. The importance of registering for biodiversity is mainly related to the characteristics of the amblypygids, which makes up one of the orders of less diverse arachnids.Keywords: Behavior; Amblypygi; Reptile; Conservation Unit.Na área do Parque Nacional da Chapada das Mesas (PNCM), ao sul do estado do Maranhão, Brasil, predominam os arenitos da Formação Sambaíba (Triássico), demonstrando ser uma área com potencial para ocorrência de cavidades naturais subterrâneas. Os ecossistemas cavernícolas não possuem cobertura vegetal e luz (afóticos). Seus recursos tróficos são oriundos de agentes físicos e bióticos externos. O trabalho de campo encontrou e identificou 87 cavernas e avaliou seu grau de relevância, incluindo levantamento bioespeleológico. Durante o esforço, dentre os representantes da fauna cavernícola do parque, um dos mais comuns foram os amblipígios do gênero Heterophrynus, animais troglófilos, com representantes encontrados em todas as zonas tropicais e semitropicais ao redor do mundo. Este grupo assume papel de consumidor terciário ou secundário nos ecossistemas onde ocorre, com registros de predação que variam de artrópodes até aves como o beija-flores (Aves, Trochilidae). Um dos registros de Heterophrynus que merece destaque, ocorreu em uma caverna que está localizada em uma região onde a vegetação predominante do entorno é o Cerradão. Nesta cavidade foi registrada uma relação trófica de predação entre um amblipígio do gênero Heterophrynus e um lagarto Tropidurus oreadicus. A importância do registro para a biodiversidade está relacionada principalmente às características dos amblipígios, que compõe uma das ordens de aracnídeos menos diversas.Palavras chave: Comportamento; Amblipígio; Réptil; Unidade de Conservação

Relato de caso: "Lacaziose (Doença de Jorge Lobo) em paciente da Amazônia Legal" / Case report: "Lacaziosis (Jorge Lobo's Disease) in a patient from Legal Amazon

A Lacaziose, ou doença de Jorge Lobo, é uma micose crônica, granulomatosa, causada por implantação traumática do fungo Lacazia loboi nos tecidos cutâneo e subcutâneo, manifestando-se clinicamente por lesões nodulares queloidianas predominantes, envolvendo sobretudo pavilhões auriculares, face, membros superiores e inferiores, e não comprometendo as mucosas. A maioria dos casos humanos está registrada em países da América do Sul de clima intertropical. Assim, o objetivo deste trabalho foi apresentar as principais manifestações clínicas e achados laboratoriais e histopatológicos de um paciente do sexo masculino, 72 anos, que apresentou os primeiros sintomas da doença aos 42 anos de idade, iniciando com nódulo assintomático na região pré-tibial de membro inferior direito, com progressão contínua das lesões. Após biópsia inconclusiva, paciente só foi diagnosticado corretamente 30 anos depois, após um aumento progressivo do tamanho da lesão, ocasião em que foram observados nódulos eritematosos e placas eritemato-infiltradas no dorso do pé direito e em região pré-tibial. Exames atestaram acantose com hiperceratose, infiltrado mononuclear, presença de fungos arredondados enfileirados, além de coloração método de Grocott positiva compatível com Lacazia loboi.  Assim, paciente foi tratado com Itraconazol de 200mg, que não ocasionou efeitos colaterais. Apresentou redução parcial das lesões dermatológicas após 4 meses do tratamento e o paciente optou por não realizar o tratamento cirúrgico

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Different Stages of Alveolar Bone Repair Process Are Compromised in the Type 2 Diabetes Condition: An Experimental Study in Rats

The aim of this study was to analyze the stages of the alveolar bone repair in type 2 diabetic rats evaluating the mechanism of mineralization and bone remodeling processes after dental extraction. Forty-eight rats were divided into normoglycemic (NG) and type 2 diabetes (T2D) groups. The upper right incisor was extracted and after 3, 7, 14 and 42 days the animals were euthanized. The following analyses were performed: immunolabeling against antibodies TNFα, TGFβ, IL6, WNT, OCN and TRAP, collagen fibers maturation, microtomography and confocal microscopy. Data were submitted to statistical analysis. The immunolabeling analysis showed that the T2D presented a more pronounced alveolar inflammation than NG. Labeling of proteins responsible for bone formation and mineralization was higher in NG than T2D, which presented greater resorptive activity characterized by TRAP labeling. Also, T2D group showed a decrease in the amount of collagen fibers. Micro-CT analysis showed that T2D causes a decrease in bone volume percentage due to deficient trabecular parameters and higher porosity. The T2D bone dynamics show a loss in bone remodeling process. T2D prolongs the local inflammatory process, which impairs the organization and maturation of collagen fibers, delaying bone formation that generates impact on mineralization and bone turnover

3er. Coloquio: Fortalecimiento de los Colectivos de Docencia

Las memorias del 3er. Coloquio de Fortalecimiento de Colectivos de Docencia deben ser entendidas como un esfuerzo colectivo de la comunidad de académicos de la División de Ciencias y Artes para el Diseño, en medio de la pandemia COVID-19, con el fin de: • Analizar y proponer acciones concretas que promuevan el mejoramiento de la calidad docente en la División. • Proponer acciones que permitan continuar fortaleciendo los cursos con modalidad a distancia (remotos). • Ante un escenario que probablemente demandará en el mediano plazo, transitar del modelo remoto a un modelo híbrido, proponer acciones a considerar para la transición de los cursos. • Planear y preparar cursos de nivelación de conocimientos, para cuando se transite a la impartición de la docencia de manera mixta o presencial, dirigidos a los alumnos que no hayan tenido oportunidad de desarrollar actividades relevantes para su formación, como prácticas de talleres y laboratorios, visitas, o alguna otra actividad relevante

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
