2. Hereditary angioedema: a disease seldom diagnosed by pediatricians
Abstract Objectives: To describe the hereditary angioedema to improve awareness of this condition and reduce diagnostic delay. Data sources: Relevant articles in the MEDLINE database through PubMed. Data synthesis: Hereditary angioedema is rare and has an autosomal dominant pattern of inheritance. Its onset occurs mainly in childhood, but there is an impo

3. EFECTO DE LA ADICIÓN DE POLÍMEROS DE CADENA CORTA SOBRE LA ESTRUCTURA QUÍMICA, PROPIEDADES MECÁNICAS, TÉRMICAS Y BIOLÓGICAS DE POLIURETANOS SINTETIZADOS CON DIISOCIANATOS ALIFÁTICOS Y ACEITE DE HIGUERILLA
The objective of this research was to synthesize biocompatible polyurethanes, with suitable mechanical properties to be used as biomaterials. Polyurethanes were synthesized with polyols derived from castor oil and isophorone diisocyanate (IPDI), hexamethylene diisocyanate and 4,4’-methylenebis (cyclohexyl isocyanate), with the addition of polycaprolactone/

4. Investigation of mental health among hospital workers in the COVID-19 pandemic: a cross-sectional study
ABSTRACT BACKGROUND: The rapid spread of the COVID-19 epidemic has led to extraordinary measures taken worldwide, and has led to serious psychological disorders. Healthcare professionals face greater severity of stress burden, due both to their direct contact with patients with the virus and to the isolation dimension of this outbreak. OBJECTIVE: To examin

5. Avaliação de matéria orgânica, densidade e porosidade do latossolo vermelho em contato com lixiviado de resíduos sólidos urbanos
RESUMO O objetivo do trabalho é avaliar a densidade, a porosidade e a matéria orgânica do solo decorrentes da interação solo-lixiviado em um latossolo vermelho, em duas profundidades: 0,2 e 1,5 m. As amostras de solo foram coletadas indeformadas, e o lixiviado em aterro foi controlado. Utilizaram-se colunas de difusão, sem fluxo, onde o solo ficou subm

6. O momento da tragédia: o papel da educação e da saúde na perspectiva da justiça social
O artigo aborda um tema ainda pouco debatido no campo da Educação e da Saúde, apesar de todos os avanços das tecnologias da informação e comunicação (TICs), que nos põem em contato com acontecimentos trágicos e catastróficos que ocorrem no mundo a toda hora. O texto parte da análise do “momento da tragédia”, questionando o antes e o depois,

7. Fatores que Influenciam a Escolha da Especialização Médica pelos Estudantes de Medicina em uma Instituição de Ensino de Curitiba (PR)
RESUMO A escolha da especialidade médica é de suma importância para o estudante de Medicina, uma vez que representa a escolha da sua prática diária. Embora a realização acadêmica, considerações financeiras e preferências de estilo de vida influenciem a escolha, os aspectos intrapessoais têm impacto na decisão do médico. Objetivos Avaliar os p

8. Anisotropic Strength of Granular Material Considering Fabric Evolution
Abstract The effect of fabric anisotropy on strength has not been considered in most strength criterions for granular material. Some criterions can describe the variation of material strength with stress-induced anisotropy, but micro-mechanism and physical meanings are undefined. Some criterions consider the effect of fabric anisotropy, but the evolution of

9. Flexural Strengthening of Reinforced Concrete Beams Using Carbon Fiber Reinforced Polymer (CFRP) Sheets with Grooves
Abstract The most common method used to strengthening, rehabilitation or repairing of reinforced concrete (RC) members is to use external carbon fiber reinforced polymer (CFRP) sheets. CFRP can greatly improve the flexural and shear capacity of deteriorated members and therefore extends their useful life. The main problem of external CFRP is the debonding of

10. 3-D finite element analysis of the effects of post location and loading location on stress distribution in root canals of the mandibular 1st molar
Abstract Objective The purpose of this study was to evaluate, by using finite element analysis, the influence of post location and occlusal loading location on the stress distribution pattern inside the root canals of the mandibular 1st molar. Material and Methods Three different 3-D models of the mandibular 1st molar were established: no post (NP) – a

11. Effect on adhesion of a nanocapsules-loaded adhesive system
Abstract This study aimed to evaluate the in situ degree of conversion, contact angle, and immediate and long-term bond strengths of a commercial primer and an experimental adhesive containing indomethacin- and triclosan-loaded nanocapsules (NCs). The indomethacin- and triclosan-loaded NCs, which promote anti-inflammatory and antibacterial effects through co

12. Rolling Contact Fatigue Life of Rail for Different Slip Conditions
Abstract A three-dimensional elastic-plastic finite element analysis (FEA) is carried out to estimate the rolling contact fatigue (RCF) crack initiation life for varied slip range on the rail arising from operational variations. The wheel load produces Hertzian contact pressure. Variation in engine traction induces slip variations that evolves thermal load i
