ABSTRACT. The objective of this study was to evaluate the fermentation profile and nutritional value of Marandu grass silage (Urochloa brizantha (Hoschst.Ex. A. Rich) R. D. Webster cv. Marandu Syn. Brachiaria brizantha (Hochst. Ex A. Rich) Stapf cv. Marandu} with different levels of inclusion of dehydrated banana peel. The experiment was conducted in a completely randomized design with marandu grass with five levels of dehydrated banana peel (0, 10, 20, 30 and 40% of natural matter) with eight replicates. The data collected were submitted to analysis of variance and, when the "F" test was significant, the inclusion levels of the pre-dried banana peel were analyzed utilizing orthogonal polynomials and linear and quadratic regression models. The mean values of N-NH3 were adjusted to the linear regression model (p < 0.01), while the pH values had the lowest value of 4.3 with the inclusion of 15% of banana peel. The mean values of the gas loss (PG, P = 0.01) and the dry matter recovery (RMS; P = 0.01) were adjusted to the quadratic regression model, with a minimum point of 16.15% for losses and 21% as the maximum point for dry matter recovery. The rate of degradation potential degradability of the dry matter (SD; P = 0.74) did not vary with the inclusion of the banana peel. The potential degradability standardized at 2, 5 and 8% was adjusted to the regressive linear regression model (p < 0.01), and for each percentage point of inclusion of the banana peel, there was a reduction of 0.23, 0.14 and 0.10%, respectively. The inclusion of 10 to 20% dehydrated banana peel in the marandu grass silage improves the fermentation profile and the nutritional value of the silage. ABSTRACT Urochloa Hoschst.Ex.

RESUMO Objetivo Avaliar o papel da tomografia computadorizada de tórax em pacientes com COVID-19 que apresentaram reação em cadeia da polimerase via transcriptase reversa (RT-PCR) inicial falsamente negativa. Métodos Estudo retrospectivo de centro único que avaliou 39 pacientes com RT-PCR negativa para COVID-19, submetidos à tomografia computadorizada de tórax e que tiveram diagnóstico final clínico ou serológico de COVID-19. A classificação tomográfica visual foi avaliada de acordo com o Consenso da Radiological Society of North America e o software desenvolvido com inteligência artificial para detecção automática de achados e estimativa de probabilidade de COVID-19. Resultados Na análise tomográfica visual, somente um deles (3%) apresentou tomografia computadorizada classificada como tendo resultado negativo, 69% foram classificados como típicos e 28% como indeterminados. Na avaliação com uso de software, somente quatro (cerca de 10%) tiveram probabilidade de COVID-19 <25%. Conclusão A tomografia computadorizada pode desempenhar papel importante no manejo de casos suspeitos de COVID-19 com RT-PCR inicialmente negativa, principalmente levando-se em consideração os pacientes que estão fora da janela ideal para coleta de amostra para RT-PCR.

ABSTRACT Objective To evaluate the role of chest computed tomography in patients with COVID-19 who presented initial negative result in reverse transcriptase-polymerase chain reaction (RT-PCR). Methods A single-center, retrospective study that evaluated 39 patients with negative RT-PCR for COVID-19, who underwent chest computed tomography and had a final clinical or serological diagnosis of COVID-19. The visual tomographic classification was evaluated according to the Consensus of the Radiological Society of North America and software developed with artificial intelligence for automatic detection of findings and chance estimation of COVID-19. Results In the visual tomographic analysis, only one of them (3%) presented computed tomography classified as negative, 69% were classified as typical and 28% as indeterminate. In the evaluation using the software, only four (about 10%) had a probability of COVID-19 <25%. Conclusion Computed tomography can play an important role in management of suspected cases of COVID-19 with initial negative results in RT-PCR, especially considering those patients outside the ideal window for sample collection for RT-PCR.

Abstract Introduction: in individuals with chronic kidney disease, sarcopenia is prevalent and is associated with increased morbidity and mortality, and the occurrence of cardiovascular complications. Objective: to verify the relationship between sarcopenia and inflammation in hemodialysis patients. Methods: a cross-sectional study with 209 patients in five hemodialysis units. Demographic, socioeconomic, body composition, clinical laboratory, and functional data were collected. Sarcopenia was diagnosed according to the European Working Group on Sarcopenia in Older People (grip strength < 27 kg for men and < 16 kg for women; DEXA muscle mass < 7.0 kg/m² for men and < 5.5 kg/m² for women). Inflammation was assessed by C-reactive protein. Results: mean age was 51.9 ± 15.0 years, with a predominance of males (59.3 %). The prevalence of sarcopenia was 29.1 % and that of inflammation was 50.2 %. A Poisson regression analysis showed that sarcopenia was associated with increased hsCRP values (PR: 1.06; 95 % CI: 1.01-1.10; p-value = 0.005); BMI (PR: 0.74; 95 % CI: 0.65-0.84; p-value < 0.001); age (PR: 1.02; 95 % CI: 1.00-1.03; p < 0.001); male (PR: 5.75; 95 % CI: 3.20-10.34; p-value < 0.001); presence of diabetes mellitus (DM) (PR: 1.87; 95 % CI: 1.27-2.74; p-value < 0.001); % body fat (PR: 1.07; 95 % CI: 1.04-1.09; p-value < 0.001). Conclusion: the prevalence of sarcopenia can be considered high in this study, as well as inflammation. Being inflamed, presence of DM, being male, increasing age, and % body fat were risk factors for sarcopenia. On the other hand, increased BMI had a protective role.

Resumen Introducción: en individuos con enfermedad renal crónica, la sarcopenia es prevalente y está asociada a un aumento de la morbilidad y la mortalidad, y a la aparición de complicaciones cardiovasculares. Objetivo: verificar la relación entre sarcopenia e inflamación en pacientes en hemodiálisis. Métodos: estudio transversal de 209 pacientes en cinco unidades de hemodiálisis. Se recopilaron datos demográficos, socioeconómicos, de composición corporal, laboratorio clínico y funcional. La sarcopenia se diagnosticó conforme al Grupo de Trabajo Europeo sobre Sarcopenia en Personas Mayores (fuerza de agarre < 27 kg para hombres y < 16 kg para mujeres; masa muscular DEXA < 7.0 kg/m² para hombres y < 5.5 kg/m² para mujeres). La inflamación se evaluó mediante la proteína C-reactiva. Resultados: la edad media fue de 51,9 ± 15,0 años, con predominio de varones (59,3 %). La prevalencia de la sarcopenia fue del 29,1 % y la de la inflamación del 50,2 %. El análisis de regresión de Poisson mostró que la sarcopenia se asociaba con un aumento de los valores de hsCRP (PR: 1,06; IC del 95 %: 1,01-1,10; valor de p = 0,005); IMC (PR: 0,74; IC del 95 %: 0,65-0,84; valor p < 0,001); edad (PR: 1,02; IC 95 %: 1,00-1,03; p < 0,001); hombre (PR: 5,75; IC 95 %: 3,20-10,34; valor p < 0,001); presencia de diabetes mellitus (DM) (PR: 1,87; IC 95 %: 1,27-2,74; valor p < 0,001); % de grasa corporal (PR: 1,07; IC 95 %: 1,04-1,09; valor p < 0,001). Conclusión: la prevalencia de la sarcopenia puede considerarse alta en este estudio, así como la inflamación. Tener inflamación, la presencia de DM, ser hombre, la mayor edad y el % de grasa corporal resultaron ser factores de riesgo de sarcopenia. Por otro lado, el aumento del IMC tuvo un papel protector.

Resumo O e-SUS é um software que instrumentaliza o processo de trabalho em saúde no Brasil. Dentre os dados de cadastro da população há o registro do uso de plantas medicinais na Atenção Básica (AB) à saúde. O objetivo do trabalho foi analisar esses registros no e-SUS em uma Unidade Básica de Saúde (UBS) no Vale do Jequitinhonha e realizar uma pesquisa com pessoas da mesma UBS que responderam sobre o uso de plantas medicinais. A hipótese do estudo é que embora o registro seja relevante, os dados gerados pelo software subestimam a realidade. Na pesquisa realizada com 77 usuários de uma UBS, selecionados de forma randomizada, 93,5% declararam fazer uso de plantas medicinais, enquanto nos relatórios do e-SUS apenas 0,8% dos indivíduos fazem este uso na mesma UBS. Portanto, os dados registrados ainda não podem ser utilizados para desenvolvimento de políticas de plantas medicinais na AB. O registro confiável do uso de plantas medicinais no e-SUS ainda é um desafio. É importante conscientizar os profissionais dos benefícios do preenchimento correto dos formulários para o desenvolvimento de políticas públicas que incluam o que é preconizado na Política Nacional de Plantas Medicinais visando reconhecer, orientar e valorizar o uso de plantas medicinais.

Abstract The e-SUS is a software used to computerize the health work process in Brazil. Among the population registration data is the record about the use of medicinal plants in Primary Health Care (AB). Thus, our objective was to analyze the records of the e-SUS in a Basic Health Unit (UBS) in the Jequitinhonha Valley and conduct a survey with individuals from the same UBS, where they were asked about the use of medicinal plants. The hypothesis of the study is that although the registration is relevant, the software data underestimate the reality about medicinal plants use. In a survey with 77 users of an UBS randomly selected, 93.5% reported using medicinal plants, while in e-SUS reports only 0.8% of the individuals from the same UBS use medicinal plants. Therefore, the recorded data cannot yet be used to develop medicinal plant policies in the AB. Reliable record of medicinal plant use in e-SUS is still a challenge. It is important to make professionals aware of the benefits of correctly completing the forms for the development of public policies that include what is recommended by the National Medicinal Plants Policy in order to recognize, guide and value the use of medicinal plants.

RESUMO Avaliou-se, comparativamente, através da metodologia do balanço energético, a sustentabilidade da síntese do etanol da cana-de-açúcar, irrigada com diferentes níveis de reposição da evaporação estimada no tanque Classe "A" - ECA, utilizando como fontes hídricas: efluente de esgoto doméstico tratado e água subterrânea, em Aquiraz, Ceará. O delineamento estatístico adotado foi em blocos casualizados, em parcelas subdivididas, com quatro repetições. Nas parcelas, avaliaram-se duas fontes hídricas (efluente de esgoto doméstico tratado e água subterrânea) e nas subparcelas avaliaram-se cinco diferentes níveis de irrigação (50; 75; 100; 125 e 150% da ECA). A irrigação com efluente de esgoto doméstico tratado resulta em maior dispêndio energético. A lâmina de irrigação referente a 150% da ECA é a que mais despende energia, independente da fonte hídrica. A irrigação com efluente de esgoto doméstico tratado proporciona maior rendimento energético (368,9 GJ ha-1), mediante a aplicação de uma lâmina equivalente a 781,4 mm, enquanto na irrigação com água de poço freático, a lâmina de 937,6 mm (150% da ECA) é a mais recomendada para a obtenção do maior rendimento energético (276,9 GJ ha-1). O efluente de esgoto doméstico apresenta a melhor rentabilidade energética, sendo viável sua utilização no sistema de produção da cultura.

ABSTRACT Using energy balance methodology, this study compared the sustainability of ethanol synthesis from sugarcane irrigated with different replacement levels based on the evaporation estimated in a Class A pan (ECA), using treated domestic sewage effluent and groundwater as the water source, in Aquiraz, in the State of Ceará. The adopted statistical design was of randomised blocks in split plots, with four replications. Two water sources (treated sewage effluent and groundwater) were evaluated in the plots, and five irrigation levels (50, 75, 100, 125 and 150% of the ECA) were evaluated in the split plots. Irrigation with treated domestic sewage effluent results in greater energy expenditure. The irrigation depth relative to 150% of the ECA expends the most energy, irrespective of the water source. Irrigation with treated domestic sewage effluent gives a higher energy yield (368.9 GJ ha-1) through the application of a depth of 781.4 mm, while for irrigation with groundwater, 937.6 mm (150% of the ECA) is the best recommended depth for obtaining the highest energy yield (276.9 GJ ha-1). Domestic sewage effluent gives the best energy return, and its use in systems of crop-production is viable.

RESUMO Objetivo Avaliar se os estudantes de odontologia que possuem hábitos tabagistas apresentam alterações celulares nas células epiteliais da mucosa jugal sobre as áreas nucleares (AN), citoplasmáticas (AC) e na relação núcleo/citoplasma (AN/AC) quando comparados a não fumantes. Métodos Trata-se de um estudo experimental, descritivo com grupo controle. A amostra foi composta por 40 estudantes de graduação em odontologia (20 fumantes e 20 não fumantes). Consideraram-se fumantes aqueles indivíduos que fumavam diariamente, no mínimo, cinco a seis cigarros do tipo industrializado; e não fumantes aqueles indivíduos que relataram a não experiência com qualquer tipo de fumo. As amostras de células epiteliais foram obtidas da mucosa oral pela técnica de citologia esfoliativa em meio líquido. As lâminas foram processadas em laboratório, coradas pela técnica de Papanicolau e analisadas através de um sistema de análise de imagens (Analysis getlt). Um questionário estruturado foi aplicado com o intuito de mensurar variáveis independentes referentes às características pessoais, comportamentos em saúde e estilo de vida. Resultados Os valores obtidos no grupo dos fumantes para a AN (169,4 µm² ± 17,0), AC (1240,1 µm² ± 128,9) e na relação AN/AC (0,1375 ± 0,01743) não apresentaram resultados com diferenças expressivas quando comparados ao grupo controle AN (170,7 µm² ± 20,0), AC (1255,3 µm² ± 174,5) e na AN/AC (0,1380 ± 0,01436). Conclusão Não foi possível observar alterações celulares significantes nas AN, AC e na relação AN/AC de células epiteliais da mucosa oral. Outros fatores de risco associados ao tabaco devem ser estudados, principalmente o tempo de exposição às propriedades do agente causador.

ABSTRACT Objective To evaluate if dental students with the habit of smoking exhibit alterations in the epithelial cells of the cheek mucosa on the nuclear area (NA), cytoplasmic area (CA) or in the nucleus/cytoplasm ratio (NA/CA), when compared to non-smokers. Methods This is a descriptive, experimental study using a control group. The sample comprised 40 dental undergraduates (20 smokers and 20 non-smokers). Individuals who smoked at least 5 or 6 cigarettes a day were deemed to be smokers, while non-smokers were those who reported having no experience of any form of smoking. The samples of epithelial cells were obtained from the oral mucosa using the liquid-based exfoliative cytology technique. The slides were processed in the laboratory, stained using the Papanicolau technique and were analyzed via an image analysis system (analySIS getIT). A structured questionnaire was applied with the aim of measuring independent variables related to personal characteristics, health and lifestyle behavior. Results The values obtained in the group of smokers were as follows: NA (169.4 µm² ± 17.0), CA (1240.1 µm² ± 128.9) and NA/CA ratio (0.1375 ± 0.01743). The results did not evidence significant differences when compared to the control group: NA (170.7 µm² ± 20.0), CA (1255.3 µm² ± 174.5) and NA/CA (0.1380 ± 0.01436). Conclusion It was not possible to observe significant cell alterations in the NA, CA or the NA/CA ratio of epithelial cells of the oral mucosa. Other risk factors associated with tobacco should be studied, principally the length of exposure to the properties of the causative agent.

RESUMO Buscou-se identificar na literatura os principais obstáculos e dificuldades enfrentadas por pessoas surdas quanto ao acesso à saúde. Trata-se de uma revisão integrativa de literatura, considerando estudos publicados entre 2006 e 2016, utilizando combinações de descritores controlados. As bases de dados virtuais utilizadas foram: LILACS, PUBMED e SciELO, incluindo artigos publicados em Inglês, Português e Espanhol. A amostra final foi composta por 24 artigos, selecionados após análise dos títulos, resumos e textos na íntegra. Os estudos selecionados foram categorizados quanto às principais temáticas e dificuldades enfrentadas pela comunidade surda, sendo principalmente relacionadas à barreira comunicacional existente entre ouvintes e surdos. Tal fato culmina em interferências na relação profissional-paciente, compreensão deficitária das pessoas surdas quanto ao processo saúde-doença e as dificuldades de integração da pessoa surda na comunidade. Na maioria dos estudos analisados, evidenciou-se que as dificuldades enfrentadas pelas pessoas surdas quando buscam atendimento em saúde são ligadas à comunicação, bem como desconhecimento de Língua Brasileira de Sinais (LIBRAS) por grande parte dos profissionais de saúde. Além disso, também há a necessidade de familiar ou intérprete presente durante a consulta e a falta de compreensão de grande parte da comunidade surda como sujeitos bilíngues e multiculturais.

ABSTRACT The main obstacles faced by deaf people in access to healthcare services were investigated in the literature. This is an integrative literature review, considering studies published between 2006 and 2016, using combinations of controlled descriptors. The virtual databases used were: LILACS, PUBMED and SciELO, including articles published in English, Portuguese and Spanish. The final sample was composed of 24 articles, selected after analysis of titles, abstracts and full texts. The elected studies were categorized according to themes and to the presented difficulties, mainly concerning communication obstacles between deaf and normally hearing people. This fact interferes on the doctor-patient relationship, producing a poor understanding by the deaf community about the health-disease process and causing a challenging integration of those people in the society. The majority of the analyzed studies indicated that the main obstacles faced by the deaf regarding the access to healthcare services are communication related, especially the healthcare professionals unfamiliarity with the Brazilian Sign Language (LIBRAS). In addition, there is also the need for a family member or interpreter to be present during the consultation. Furthermore, the lack of perception on the hearing society part, of the deaf community as bilingual and multicultural subjects, was verified.

RESUMO Esta pesquisa descreve o consumo de bebidas alcoólicas e a presença de fatores associados entre acadêmicos de Odontologia. É um estudo transversal com 172 acadêmicos de Odontologia, cujos dados foram obtidos por meio de questionários com questões referentes às características do consumo de álcool e à existência ou não de fatores associados a este hábito. Os resultados apontam que 58,7% dos entrevistados relataram uso de bebidas alcoólicas, sendo a maioria do sexo masculino. Esquecer problemas e sentir-se bem foram os principais fatores motivacionais relatados. Problemas familiares e a perda de objetos foram as consequências mais observadas. A relação entre sexo e consumo mostrou-se estatisticamente significante. A relação entre sexo e as variáveis relacionadas ao consumo de álcool foi significativa para “uso em eventos sociais”, “fazer amigos” e “sentir-se bem em eventos sociais”.Foi observado consumo elevado e preocupante de bebidas alcoólicas entre os acadêmicos.

ABSTRACT This study aimed to describe the use of alcohol and the presence of associated factors among dental students. Cross-sectional in nature, the study surveyed 172 dental students, whose data was obtained through questionnaires with questions regarding the characteristics of their alcohol consumption and the presence or absence of factors associated with this habit. The results show that 58.7% of respondents reported using alcohol, with the incidence higher among male students. The main reported motivating factors were forgetting their problems and feeling good, with the most frequently observed consequences family problems and losing belongings. The relationship between gender and consumption was statistically significant. The relationship between sex and the variables related to alcohol consumption was significant for “use in social events”, “making friends” and “feeling good at social events”.The overall findings suggested excessive and worrying levels of alcohol consumption among students.

RESUMO: trata-se de uma revisão integrativa que objetivou analisar a produção científica sobre a educação inclusiva no ensino superior. Os dados foram coletados nas bases de dados Lilacs, Scielo, Cochrane, Medline e PubMed, entre os anos 2005 e 2014, utilizando-se os descritores controlados Special Education, Education Higher, Mainstreaming Education e Disabled Personse e os descritores não controlados Educação Especial, Educação Superior, Inclusão Educacional e Pessoas com Deficiência; Educación Superior, Propensíon Educación, Personas com Discapacidad. A amostra constituiu em 16 artigos. As publicações sobre a educação inclusiva no ensino superior têm sido tênues, demonstrando que ainda há muito a avançar nesse assunto. Conclui-se que o tema educação inclusiva é mais estudado em relação às crianças; as atenções dos estudiosos em relação a pessoas adultas com necessidades especiais envolvem mais a assistência em saúde e não a educação inclusiva no ensino superior.

ABSTRACT: it is an integrative review that aimed to analyze the scientific literature on inclusive education in higher education. Data was collected in the following databases: Lilacs, SciELO, Cochrane, Medline and PubMed, between the years 2005 and 2014, using the controlled descriptors Special Education, Higher Education, Education and Mainstreaming Disabled Person and uncontrolled descriptors Special Education, Higher Education, Educational Inclusion and Persons with Disabilities; Educación Superior, Propensíon Educación, Personas com Discapacidad. The sample consisted of 16 articles. The publications on inclusive education in higher education has been tenuous, demonstrating that there is still much to advance in this issue. We conclude that the issue of inclusive education is more studied in relation to children; and that the attention of scholars regarding adults with special needs involves mostly health care and not inclusive education in higher education.

Abstract Multicystic and unicystic ameloblastomas are benign odontogenic tumors that present distinct biological behavior. The investigation of stem cells has become an important branch of tumor biology, with several studies addressing the possible role of these cells in tumor growth, angiogenesis, progression, infiltration and invasiveness. This study evaluated the immunohistochemical expression of CD90(Thy-1) and P75NTR stem cell markers in multicystic and unicystic ameloblastomas. Seventeen (17) samples of ameloblastomas (multicystic, n = 10; unicystic, n = 7) were submitted to immunohistochemical reactions and graded semi-quantitatively. The Kolmogorov-Smirnov test was used to verify possible differences in CD90 and P75NTR expressions between multicystic and unicystic ameloblastomas (p < 0.05). CD90 immunostaining was observed in all multicystic ameloblastoma specimens (n = 10), in the cytoplasm of the fibroblasts and vascular endothelial cells of the tumor stroma, near the neoplastic odontogenic epithelia. The staining of stromal CD90 was significantly higher in multicystic than in unicystic ameloblastomas (p = 0.003). Nuclear P75NTR immunostaining was observed in all ameloblastoma specimens. A significant difference was seen in the epithelial staining of P75NTR between multicystic and unicystic types (p = 0.007). The increased expression of CD90 and P75NTR found in multicystic ameloblastomas suggests a behavioral biological difference between multicystic and unicystic ameloblastomas, as well as a difference in ameloblastoma development.

INTRODUÇÃO: A dissecção endoscópica da submucosa (DES) de neoplasias precoces do trato gastrointestinal (TGI) tem sido cada vez mais aplicada como alternativa aos procedimentos cirúrgicos invasivos, visando a preservar o órgão e a qualidade de vida do paciente, contudo, não possibilita a avaliação histopatológica de linfonodos. Estudos anteriores demonstraram que a presença de êmbolos neoplásicos, em vasos linfáticos (invasão vascular linfática [IVL]) ou sanguíneos (invasão vascular sanguínea [IVS]), é considerada um fator preditivo positivo para ocorrência de metástase linfonodal. A avaliação da invasão vascular realizada apenas pela coloração de rotina hematoxilina e eosina (HE) pode gerar resultados falso-positivos e falso-negativos. O D2-40 é um anticorpo monoclonal específico para endotélio linfático, sendo, portanto, útil para identificar IVL e distinguir se a embolização tumoral encontra-se em vasos sanguíneos ou linfáticos. OBJETIVO: Determinar o papel do estudo imuno-histoquímico (IHQ) na avaliação de espécimes de DES, comparando a detecção de IVL e IVS, pelo HE e IHQ com marcação por D2-40 e CD34. MÉTODO: Foi realizado estudo IHQ utilizando os marcadores D2-40 e CD34 (pan-endotelial) em 30 casos de produtos de DES com diagnóstico histológico de carcinoma para avaliar a presença de IVL e IVS. RESULTADOS: A detecção de IVL foi maior que a de IVS. Dos seis casos com IVL ao HE, três eram falso-positivos e seis, falso-negativos à IHQ. Em relação à IVS, foram identificados cinco casos falsopositivos e um falso-negativo à IHQ. CONCLUSÃO: Nossos resultados indicaram que a análise histopatológica dos produtos de DES realizando apenas a coloração HE não permite a avaliação adequada da presença de IVS ou IVL.

INTRODUCTION: Endoscopic submucosal dissection (ESD) of early neoplasias of the gastrointestinal tract (GIT) has been increasingly applied as an alternative to invasive surgical procedures, with the aim to preserve the patient's organ and quality of life, although it does not allow the histopathological analysis of lymph nodes. Previous studies demonstrated that the presence of neoplastic emboli in lymphatic (lymphatic vascular invasion [LVI]) or blood vessels (blood vascular invasion [BVI]) is considered a positive predictive factor for the occurrence of lymph node metastasis. The assessment of vascular invasion carried out only by routine hematoxylin and eosin staining (HE) may yield both falsepositive and false-negative results. D2-40 is a specific monoclonal antibody to the lymphatic endothelium. Thus, it is useful for identifying LVI and distinguishing if tumor embolization is found in blood or lymphatic vessels. OBJECTIVE: To determine the role of immunohistochemistry (IHC) in the assessment of ESD specimens by comparing the detection of LVI and BVI by HE and IHC with D2-40 and CD34 immunolabeling. METHOD: We conducted the IHC study using D2-40 and CD34 markers (pan-endothelial) in 30 cases of ESD with histological diagnosis of carcinoma in order to assess the presence of LVI and BVI. RESULTS: The detection of LVI was more prevalent than BVI. Three out of six cases with LVI were false-positive by HE and six were false-negative by IHC. Regarding BVI, five cases were identified and one was false-negative by IHC. CONCLUSION: Our results indicated that the histopathological analysis of ESD specimens by exclusively routine HE staining does not allow proper evaluation of BVI or LVI.

Asphaltenes from two Brazilian crude oils were submitted to mild oxidation to disrupt their structure, releasing the occluded oil. The released hydrocarbons were compared with those from the original crude oil, and used to evaluate the alteration of the oils, especially as a result of biodegradation, but also thermal maturity. The crude oils used are depleted in n-alkanes, which are usually related to biodegradation. However, the released products from the corresponding asphaltenes have n-alkane distributions from nC10 to nC40, suggesting a protection effect from biodegradation. The m/z 191 mass chromatograms showed higher relative intensities for tricyclic terpanes than the hopanes in the crude in comparison with the released ones.
