Resumen Antecedentes: El Área de Protección de Recursos Naturales Quebrada de Santa Bárbara (APRNQSB) destaca por su biodiversidad y la coexistencia de seis géneros de coníferas, pero carece de un inventario florístico actualizado y completo, por lo que el objetivo de este trabajo fue generarlo y caracterizar su vegetación. Preguntas: ¿Cuál es la riqueza, el riesgo de extinción y distribución de la flora vascular y qué tipos de vegetación forman en el APRNQSB? Especies estudiadas: Traqueofitas. Sitio y años de estudio: APRNQSB, Durango; julio 2018 a septiembre 2019. Métodos: Un listado preliminar conjuntó registros del herbario CIIDIR y colecciones virtuales. Se enriqueció mediante recolectas en 15 estaciones y cuatro senderos de referencia. Las especies se catalogaron por su riesgo de extinción y distribución. La riqueza florística se comparó contra 11 inventarios de otras zonas de México mediante un índice de diversidad taxonómica (IDT). La vegetación se caracterizó por composición florística y fisonomía. Resultados: La flora vascular incluyó 79 familias, 211 géneros, 352 especies y un IDT de 198 spp./km2. Se registraron seis especies bajo la NOM-059-SEMARNAT-2010, 63 taxa en la UICN, 34 especies endémicas a Durango y estados vecinos y 17 microendémicas. La vegetación se compone por bosque mixto de Pinus-Quercus, bosque de coníferas y vegetación acuática y subacuática. Conclusiones: Considerando trabajos previos, se logró un incremento del 76 % en el inventario de la flora vascular del APRNQSB. Los datos actualizados de la flora del APRNQSB son fundamentales para el desarrollo y establecimiento de estrategias de manejo y conservación.

Abstract Background: Quebrada de Santa Bárbara Natural Resources Protection Area (QSBNRPA) stands out for its biodiversity and the coexistence of six genera of conifers, but an updated and complete floristic inventory is not available; hence the objective of this work was to generate it and characterize its vegetation. Questions: What is the diversity, extinction risk, and distribution of the vascular flora and what types of vegetation develop in the QSBNRPA? Studied species: Tracheophytes. Study site and dates: QSBNRPA, Durango; July 2018 to September 2019. Methods: A preliminary list assembled database records from the CIIDIR herbarium and virtual collections. It was enriched by collected specimens at 15 stations and four reference trails. The species were catalogued by their extinction risk, endemicity and distribution. Species richness was compared against 11 inventories from other Mexican zones using a taxonomic diversity index (TDI). The vegetation was characterized by its physiognomy and taxonomic composition. Results: The vascular flora included 79 families, 211 genera and 352 species, with a TDI of 198 spp./km2. Six species at risk included in NOM-059-SEMARNAT-2010, 63 taxa listed in the IUCN, 34 endemic species to Durango and neighboring states, and 17 microendemics were recorded. The vegetation composition includes Pinus-Quercus mixed forest, coniferous forest, and acuatic and subacuatic vegetation. Conclusions: Considering previous works, an increase of 76 % was achieved in the inventory of the vascular flora of the APRNQSB. The updated data of the flora of the APRNQSB are fundamental for the development and establishment of strategies of management and conservation.

ABSTRACT Diets with high energy density and additives that enhance energy use are necessary for finishing feedlot cattle. The objective of the present study was to evaluate the performance, ingestive behavior, apparent digestibility of the diet and the carcass traits of feedlot steers fed concentrates from different energy sources, one derived from starchy sources and the other, from lipid sources, combined or not with whole soy lecithin, at a dose of 40 g animal day-1. The experimental design was completely randomized blocks, in a 2 x 2 factorial arrangement. The combination of whole soy lecithin with the lipid energy source concentrate increased the dry matter digestibility and the carcass yield of the animals (76.03% and 57.20%, respectively). The lipid energy source concentrate showed higher ether extract digestibility and animals fed on it had higher carcass yield (84.18% and 56.85%, respectively). Whole soy lecithin promoted a reduction in fecal pH due to a greater fermentation of carbohydrates and fatty acids in the intestinal lumen. Using whole soy lecithin combined with energy concentrate from a lipid source is recommended due to its improvements in the use of the diet and in the carcass yield.

RESUMO O uso de dietas com alta densidade energética e aditivos que potencializem o aproveitamento energético se faz necessário na terminação de bovinos em confinamento. O objetivo do presente estudo foi avaliar o desempenho, o comportamento ingestivo, a digestibilidade aparente da dieta e as características de carcaça de novilhos confinados, alimentados com concentrados de diferentes fontes energéticas, um derivado de fontes amiláceas e outro de fontes lipídicas, associados ou não com lecitina integral de soja, na dose de 40g animal dia-1. O delineamento experimental foi o de blocos inteiramente ao acaso, em esquema fatorial 2 x 2. A associação da lecitina integral de soja com o concentrado de fonte energética lipídica melhorou a digestibilidade da matéria seca e o rendimento de carcaça dos animais (76,03% e 57,20%, respectivamente). O concentrado de fonte energética lipídica teve maior digestibilidade do extrato etéreo, e os animais alimentados com este possuíram maior rendimento de carcaça (84,18% e 56,85%, respectivamente). A lecitina integral de soja isolada promoveu redução no pH fecal em virtude de uma maior fermentação de carboidratos e ácidos graxos no lúmen intestinal. Utilizar lecitina integral de soja associada com concentrado energético de fonte lipídica é recomendado devido a suas melhorias no aproveitamento da dieta e no rendimento de carcaça.

ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

Abstract. Technological development for Gymnotus sp. farming is relevant because this species has a socio- economic impact in South American regions where sport fishing is an important activity. Although Gymnotus sp. breeds in captivity, fry survival in ponds can be unacceptable for culture systems. The objective of this work was to test the response to hormonal induction of Gymnotus sp. with carp pituitary extract (CPE) and gonadotrophin-releasing hormone (GnRH) in relation to different male and female reproductive parameters. CPE treatment specimens were stripped 12 and 20 hours after the triggering dosage, and GnRH treatment specimens were stripped 10 and 12 hours after hormonal application. We could obtain positive results using CPE with a short capture-induction interval (C-II) with broodstock in mature stages of gonadal development. Percentage of oocytes with peripheral germinal vesicle (%OPGV) and oocyte diameter showed significant differences between groups treated with CPE. Oocytes could be successfully extracted from two females treated with CPE and stripped 12 hours after the last dosage. Semen was only extracted from males treated with CPE. GnRH stimulation did not give positive results because gametes could not be extracted with different doses and C-II used. This work is the first description of semen quality parameters in Gymnotus sp. Future works should focus on combining hormonal induction strategies with CPE and the management of environmental variables.

Resumen El desarrollo tecnológico para el cultivo de Gymnotus sp. es relevante porque este género tiene un impacto socioeconómico en regiones sudamericanas donde la pesca deportiva es una actividad importante. Aunque Gymnotus sp. se reproduce en cautiverio, la supervivencia de los alevines en los estanques puede ser insuficiente para un sistema de cultivo. El objetivo de este trabajo fue evaluar la respuesta de diferentes parámetros reproductivos a la inducción hormonal en Gymnotus sp. con extracto bruto de hipófisis de carpa (EBH) y hormona liberadora de gonadotrofinas (GnRH). Las muestras de gametos del tratamiento con EBH se extrajeron 12 y 20 horas después de la dosis desencadenante, las muestras del tratamiento con GnRH se extrajeron 10 y 12 horas después de la aplicación hormonal. El porcentaje de ovocitos con vesícula germinal periférica (%OVGP) y el diámetro de los ovocitos mostraron diferencias significativas entre grupos tratados con EBH con un intervalo captura-inducción (IC-I) de corta duración, con reproductores en etapas avanzadas de desarrollo gonadal. Se pudieron extraer ovocitos con éxito a dos hembras inducidas con EBH, 12 horas después de la dosis desencadenante y, además, se extrajo semen sólo de los machos inducidos con EBH. La estimulación con GnRH no dio resultados positivos en las diferentes dosis e IC-I utilizados, dado que no se pudieron extraer gametos. Este trabajo es la primera descripción de los parámetros de calidad del semen en Gymnotus sp. Futuras líneas de trabajo deberán centrarse en el manejo de variables ambientales para establecer una estrategia de reproducción que se pueda utilizar a nivel productivo.

RESUMO Este estudo teve como objetivo caracterizar genótipos de M. synoviae circulantes em poedeiras comerciais, na Região Sudeste do Brasil. Para estabelecer a relação evolutiva entre as cepas de MS, foi analisada a sequência genética do gene vlhA de 11 cepas de MS identificadas no Rio de Janeiro e em São Paulo, de 10 outras cepas de MS identificadas no Brasil e cujas sequências foram depositadas no banco de dados GenBank, e da cepa vacinal MSH. O método da máxima verossimilhança e o modelo de Kimura com dois parâmetros foram utilizados para comparar as cepas. As sequências obtidas foram depositadas no Genbank, sob os números de acesso OP279775 a OP279785. Foi possível verificar a presença de diferentes cepas circulantes no Brasil, com alta similaridade entre as cepas do Rio de Janeiro pela análise do gene vlhA. As duas cepas paulistas detectadas no presente estudo possuem o baixo percentual (68%) de similaridade, demonstrando a variabilidade das cepas dessa localidade.

Abstract: En | Text: En | PDF: En

Phenylphosphonates of zinc (Zn-PPh), calcium (Ca-PPh) and magnesium (Mg-PPh) were synthesized by the hydrothermal method. Samples showed characteristic X-ray diffraction (XRD) patterns of layered compounds with basal spacing in the range of 14-15 Å. According to Fourier transform infrared spectroscopy (FTIR), all compositions showed the presence of characteristic bands attributed to phenyl aromatic rings, phosphonate and lattice metal-oxygen (M-O) vibrations. Different concentrations of phenylphosphonate particles were applied to stabilize water-in-oil Pickering emulsions using vaseline oil in different w/o fractions. The three particle types showed greater affinity for the oil phase (wettability) and the ability to stabilize the emulsions via the Pickering effect. Ca-PPh particles contained a greater emulsified fraction after 20 days of evaluation. This result can be attributed to the particle morphology observed by scanning electron microscopy (SEM). The fibrous morphology of Ca-PPh particles is believed to increase the steric hindrance effect at the surface around the droplets, while the Zn-PPh and Mg-PPh layered particles tended to form clusters.

Abstract We investigated whether racial discrimination accelerates the weight and Body Mass Index (BMI) gain in Blacks and Browns participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) in four years of follow-up. We compared body weight and BMI between the 1st (2008-2010) and 2nd visit (2012-2014) of 5,983 Blacks and Browns participants. Exposure to racial discrimination and covariates (age, sex, education, and research center) were obtained at the 1st visit. Linear mixed effects models stratified by race/skin color were used. Report of racial discrimination was more frequent among Blacks (32.1%) than Browns (6.3%). During the follow-up period, Blacks and Browns gained an average of 1.4kg and 1.2kg, respectively. This increase was greater among those who reported discrimination when compared to those who did not, both in Blacks (2.1kg vs.1.0kg, p < 0.001) and Browns (1.9kg vs. 1.1kg, p < 0.05). The results of the interaction between racial discrimination and time showed that Blacks, but not Browns, who reported racial discrimination had greater weight and BMI gains between visits. Our results suggest that reducing racial discrimination would contribute to prevent and/or control obesity increase in the country.

Resumo Investigou-se se a discriminação racial acelera o ganho de peso corporal e o Índice de Massa Corporal (IMC) em pretos e pardos participantes do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) em quatro anos de seguimento. Comparou-se o peso corporal e o IMC entre a 1ª (2008-2010) e a 2ª visita (2012-2014) de 5.983 participantes pretos e pardos. A exposição à discriminação racial e às covariáveis (idade, sexo, escolaridade e centro de pesquisa) foram obtidas na 1ª visita. Foram utilizados modelos lineares de efeitos mistos estratificados por raça/cor da pele. O relato de discriminação racial foi mais frequente entre pretos (32,1%) do que em pardos (6,3%). Durante o período de acompanhamento, pretos e pardos ganharam uma média de 1,4kg e 1,2kg, respectivamente. Esse aumento foi maior entre os que relataram discriminação, quando comparados aos que não relataram, tanto em pretos (2,1 kg vs. 1,0 kg, p < 0,001) quanto em pardos (1,9kg vs. 1,1kg, p < 0,05). Após ajustes, os pretos, mas não os pardos, que relataram discriminação racial apresentaram maiores ganhos de peso e IMC entre as visitas. Nossos resultados sugerem que a redução da discriminação racial pode contribuir para prevenir e/ou controlar o aumento da obesidade no país.

RESUMO Práticas inadequadas de manejo antes do abate podem comprometer o bem-estar animal e a qualidade da carne suína. Este estudo visou avaliar os efeitos do período de transporte (TT), período de descarga (TD), e período de pré-abate (TE) nos indicadores termofisiológicos animais e no pH da carne suína, utilizando uma abordagem multivariada. Este estudo foi realizado num matadouro localizado em Aquiraz, Ceará, Brasil. Um total de 60 suínos mestiços com 107 ± 5 kg de peso corporal foram distribuídos em três grupos experimentais: grupo A (TT = 180 min, TD ≤ 10 min, e TE = 24 horas), grupo B (TT = 60 min, TD ≤ 15 min, e TE = 18 horas), e grupo C (TT = 45 min, TD ≤ 5 min, e TE = 24 horas). A análise discriminante canônica foi implementada e as diferenças entre tratamentos são representadas graficamente. Os dois primeiros componentes foram responsáveis por 97% dos tratamentos. A análise discriminante mostrou que o grupo C apresentou diferenças multivariadas em relação aos outros, particularmente com temperatura retal elevada antes do abate (38,4 ± 0,23 °C) e frequência respiratória (131 ± 7,0 respirações min-1) e temperatura retal (39,7 ± 0,18 °C) à chegada ao matadouro. O período de transporte (TT), período de descarga (TD) e o stress térmico das instalações influenciaram variáveis fisiológicas, tais como a temperatura retal e a frequência respiratória. Além disso, as variáveis de estresse fisiológico também favoreceram cortes com pH básico, resultando em perda de qualidade.

ABSTRACT Inadequate pre-slaughter handling practices may compromise animal welfare and pork quality. This study aimed to evaluate the effects of transport period (TT), unloading period (UT), and pre-slaughtering period (WT) on animal thermophysiological indicators and pork pH using a multivariate approach. This study was conducted in a slaughterhouse located in Aquiraz, Ceará state, Brazil. A total of 60 mestizo pigs with 107 ± 5 kg body weight were distributed into three experimental groups: group A (TT = 180 min, UT ≤ 10 min, and WT = 24 hours), group B (TT = 60 min, UT ≤ 15 min, and WT = 18 hours), and group C (TT = 45 min, UT ≤ 5 min, and WT = 24 hours). Canonical discriminant analysis was implemented and the differences between treatments are represented graphically. The first two components accounted for 97% treatments. The discriminant analysis showed that group C presented multivariate differences in relation to others, particularly with high rectal temperature before slaughter (38.4 ± 0.23 °C) and respiratory rate (131 ± 7.0 breaths min-1) and rectal temperature (39.7 ± 0.18 °C) upon arrival at the slaughterhouse. Transport period (TT), unloading period (UT), and thermal stress of the facilities influenced physiological variables, such as rectal temperature and respiratory rate. Furthermore, the physiological stress variables also favored cuts with basic pH, resulting in quality loss.

RESUMO O desempenho dos subsoladores pode ser influenciado pelos restos culturais no solo através dos diferentes tipos de cobertura vegetal. Em qualquer um desses sistemas de cobertura, o uso de subsoladores para descompactação altera as propriedades físicas do solo. O presente estudo teve como objetivo avaliar os atributos físicos do solo em tipos de manejo sob diferentes velocidades de deslocamento e profundidades na operação de subsolagem. O experimento foi conduzido no IF Goiano, Campus Morrinhos, Goiás, Brasil. O delineamento inteiramente casualizado foi usado em esquema de parcelas subdivididas com 12 tratamentos e cinco repetições, totalizando 60 plarcelas. Os fatores corresponderam a duas áreas de manejo (sequeiro e pastagem), duas velocidades de operação de subsolagem (2,5 e 4,5 km h-1) e três profundidades do solo (0,00-0,015; 0,15-0,30 e 0,30-0,45 m). A parcela principal foi constituída pelas duas áreas de manejo e a subparcela a combinação dos outros dois fatores. Foram avaliados a resistência à penetração, densidade do solo, teor de água, mobilização do solo e expansão volumétrica do solo. Posteriormente, os valores encontrados foram submetidos à análise de variância e teste de Tukey p ≤ 0,05. A resistência à penetração e a densidade aparente foram diferentes antes e após a subsolagem. As velocidades de subsolagem alteraram os valores de resistência à penetração e mobilização do solo. As áreas de pastagem apresentaram maior resistência à penetração das raízes e proporcionaram menor teor de água e favoreceram maior expansão volumétrica do solo.

ABSTRACT Subsoiler performance can be influenced by crop residue in the soil through different types of vegetation cover. In any of these cover systems, the use of subsoilers for decompaction changes soil physical properties. The present study aimed to evaluate soil physical properties in different management systems using several subsoiling speeds and soil depths. The experiment was conducted at IF Goiano, Morrinhos Campus, Goiás state, Brazil. A completely randomized design was used in a split-plot scheme with 12 treatments and five replicates, totaling 60 plots. The factors corresponded to two management areas (rainfed and pasture), two subsoiling speeds (2.5 and 4.5 km h-1) and three soil depths (0.00-0.015; 0.15-0.30 and 0.30-0.45 m). The main plot consisted of the two management areas and the subplot the combination of the other two factors. Penetration resistance, bulk density, water content, soil mobilization and soil volumetric expansion were evaluated. The results were then submitted to analysis of variance and Tukey’s test (p ≤ 0.05). Penetration resistance and bulk density differed before and after subsoiling. The subsoiling speeds altered penetration resistance and soil mobilization. Pasture areas showed greater root penetration resistance, provided lower water content and favored greater soil volumetric expansion.

Abstract Hereditary transthyretin amyloidosis with peripheral neuropathy (ATTRv-PN) is an autosomal dominant inherited sensorimotor and autonomic polyneuropathy with over 130 pathogenic variants identified in the TTR gene. Hereditary transthyretin amyloidosis with peripheral neuropathy is a disabling, progressive and life-threatening genetic condition that leads to death in ~ 10 years if untreated. The prospects for ATTRv-PN have changed in the last decades, as it has become a treatable neuropathy. In addition to liver transplantation, initiated in 1990, there are now at least 3 drugs approved in many countries, including Brazil, and many more are being developed. The first Brazilian consensus on ATTRv-PN was held in the city of Fortaleza, Brazil, in June 2017. Given the new advances in the area over the last 5 years, the Peripheral Neuropathy Scientific Department of the Brazilian Academy of Neurology organized a second edition of the consensus. Each panelist was responsible for reviewing the literature and updating a section of the previous paper. Thereafter, the 18 panelists got together virtually after careful review of the draft, discussed each section of the text, and reached a consensus for the final version of the manuscript.

Resumo Polineuropatia amiloidótica familiar associada a transtirretina (ATTRv-PN) é uma polineuropatia sensitivo-motora e autonômica hereditária autossômica dominante com mais de 130 variantes patogênicas já identificadas no gene TTR. A ATTRv-PN é uma condição genética debilitante, progressiva e que ameaça a vida, levando à morte em ~ 10 anos se não for tratada. Nas últimas décadas, a ATTRv-PN se tornou uma neuropatia tratável. Além do transplante de fígado, iniciado em 1990, temos agora 3 medicamentos modificadores de doença aprovados em muitos países, incluindo o Brasil, e muitas outras medicações estão em desenvolvimento. O primeiro consenso brasileiro em ATTRv-PN foi realizado em Fortaleza em junho de 2017. Devido aos novos avanços nesta área nos últimos 5 anos, o Departamento Científico de Neuropatias Periféricas da Academia Brasileira de Neurologia organizou uma segunda edição do consenso. Cada panelista ficou responsável por rever a literatura e atualizar uma parte do manuscrito. Finalmente, os 18 panelistas se reuniram virtualmente após revisão da primeira versão, discutiram cada parte do artigo e chegaram a um consenso sobre a versão final do manuscrito.

Abstract: En | Text: En | PDF: En

Cariniana estrellensis (Raddi) Kuntze seedlings have been used in forest restoration programs in the Atlantic Forest biome. However, despite the economic and ecological relevance of this species, to date no general method for rapid identification of primary and secondary metabolites of C. estrellensis leaves has been reported. In this work, we explore the feasibility of using rapid analysis by nuclear magnetic resonance techniques and liquid chromatography coupled to diode array, charged aerosol, and mass detection. The main secondary metabolites identified were hydrolysable tannins, quinic acid, hydroxycinnamic acids (trans-p-coumaric acid, cis p coumaric acid, and trans-ferulic acid), and flavonoids (kaempferol and quercetin derivatives). These compounds are particularly useful as chemotaxonomic markers for the genus Cariniana and for the family Lecythidaceae, and may also be important for pharmacological uses and for the survival of the seedlings in reforestation programs.

Resumo O reparo por excisão de nucleotídeos (NER) atua reparando danos no DNA, como lesões causadas por cisplatina. A proteína Xeroderma Pigmentosum complementation group C (XPC) está envolvida no reconhecimento de danos pela via de reparação global do genoma pelo NER (GG-NER) e tem sido estudada em diferentes organismos devido à sua importância em outros processos celulares. Neste trabalho, estudamos proteínas do NER em Trypanosoma cruzi e Trypanosoma evansi, parasitos de humanos e animais, respectivamente. Modelos tridimensionais das proteínas XPC de T. cruzi e T. evansi foram feitos e observou-se poucas diferenças estruturais entre estas proteínas. Durante testes, a inserção do gene XPC de T. evansi (TevXPC) em T. cruzi resultou em crescimento celular mais lento em condições normais. Após o tratamento com cisplatina, T. cruzi superexpressando seu próprio gene XPC (TcXPC) foi capaz de recuperar as taxas de divisão celular mais rapidamente do que T. cruzi expressando o gene TevXPC. Com base nesses testes, sugere-se que TevXPC (sendo uma proteína exógena em T. cruzi) interfere negativamente nos processos celulares em que TcXPC (a proteína endógena) está envolvida. Isso provavelmente ocorreu pois TevXPC é capaz de interagir com algumas moléculas ou proteínas endógenas de T.cruzi, mas é incapaz de interagir com outras. Isso reforça a importância do correto funcionamento de XPC dentro da célula.

Abstract Nucleotide excision repair (NER) acts repairing damages in DNA, such as lesions caused by cisplatin. Xeroderma Pigmentosum complementation group C (XPC) protein is involved in recognition of global genome DNA damages during NER (GG-NER) and it has been studied in different organisms due to its importance in other cellular processes. In this work, we studied NER proteins in Trypanosoma cruzi and Trypanosoma evansi, parasites of humans and animals respectively. We performed three-dimensional models of XPC proteins from T. cruzi and T. evansi and observed few structural differences between these proteins. In our tests, insertion of XPC gene from T. evansi (TevXPC) in T. cruzi resulted in slower cell growth under normal conditions. After cisplatin treatment, T. cruzi overexpressing its own XPC gene (TcXPC) was able to recover cell division rates faster than T. cruzi expressing TevXPC gene. Based on these tests, it is suggested that TevXPC (being an exogenous protein in T. cruzi) interferes negatively in cellular processes where TcXPC (the endogenous protein) is involved. This probably occurred due interaction of TevXPC with some endogenous molecules or proteins from T.cruzi but incapacity of interaction with others. This reinforces the importance of correctly XPC functioning within the cell.

Resumo Os objetivos do trabalho foram descrever a estrutura histológica e histoquímica do tubo gastroesofágico da Iguana iguana e verificar a ocorrência e distribuição de células serotonina (5-HT) e somatostatina (SS) imunorreativas. Fragmentos do trato gastrointestinal (TGI) de cinco iguanas foram submetidos à técnica histológica e imunohistoquímica padrão. As células imunorreativas para 5-HT e SS foram quantificadas usando o STEPanizer. O esôfago apresenta epitélio pseudoestratificado colunar ciliado Alcian blue (AB) positivo, com células caliciformes altamente reativas ao ácido periódico de Schiff (PAS). No esôfago cervical, a densidade numérica de células 5-HT por unidade de área (QA [células 5-HT] / µm2) foi de 4.6x10-2 ± 2.0 e o esôfago celomático apresentou QA = 4.0x10-2 ± 1.0. O epitélio do estômago é colunar simples, PAS e AB positivo. As regiões cranial e média do estômago apresentaram (QA [células 5-HT] / µm2) = 6.18x10-2 ± 3.2 e a região caudal, QA = 0.6x10-2 ± 0.2. As células SS foram observadas apenas no estômago caudal, com densidade numérica (QA [células SS] / µm2) = 1.4x10-2 ± 0.9. Em I. iguana, foi observada variações em termos da distribuição das secreções de muco e padrão de ocorrência das células enteroendócrinas secretoras de serotonina e somatostatina no TGI, o que possivelmente reflete uma resposta adaptativa interespecifica.

Abstract The work aims were to describe the histological and histochemical structure of the gastroesophageal tube of Iguana iguana and verify the occurrence and distribution of immunoreactive serotonin (5-HT) and somatostatin (SS) cells. Fragments of the gastrointestinal tract (GIT) of five iguanas were which underwent standard histological and immunohistochemistry technique. Immunoreactive cells for 5-HT and SS were quantified using the STEPanizer. The oesophagus has ciliated columnar pseudostratified epithelium with staining Alcian blue (AB) + and goblet cells highly reactive to periodic acid Schiff (PAS). In the cervical oesophagus, the numerical density of 5-HT cells per unit area (QA [5-HT cells]/µm2) was 4.6x10-2 ± 2.0 and celomatic oesophagus presented QA = 4.0x10-2 ± 1.0. The epithelium of the stomach is simple columnar, PAS and AB +. The cranial and middle regions of the stomach presented (QA [5-HT cells]/µm2) = 6.18x10-2 ± 3.2 and the caudal region, QA = 0.6x10-2 ± 0.2. The SS cells were only observed in the caudal stomach, with numerical density (QA [SS cells]/µm2) = 1.4x10-2 ± 0.9 In I. iguana, variation was observed in terms of the distribution of mucus secretions and the pattern of occurrence of serotonin and somatostatin-secreting enteroendocrine cells in the TGI, which possibly will result in an interspecific adaptive response.
