    Galectin-3, histone deacetylases, and Hedgehog signaling:Possible convergent targets in schistosomiasis-induced liver fibrosis

    Get PDF
    Schistosomiasis affects approximately 240 million people in the world. Schistosoma mansoni eggs in the liver induce periportal fibrosis and hepatic failure driven by monocyte recruitment and macrophage activation, resulting in robust Th2 response. Here, we suggested a possible involvement of Galectin-3 (Gal-3), histone deacetylases (HDACs), and Hedgehog (Hh) signaling with macrophage activation during Th1/Th2 immune responses, fibrogranuloma reaction, and tissue repair during schistosomiasis. Gal-3 is highly expressed by liver macrophages (Kupffer cells) around Schistosoma eggs. HDACs and Hh regulate macrophage polarization and hepatic stellate cell activation during schistosomiasis-associated fibrogenesis. Previously, we demonstrated an abnormal extracellular matrix distribution in the liver that correlated with atypical monocyte-macrophage differentiation in S. mansoni-infected, Gal-3-deficient (Lgals3-/-) mice. New findings explored in this review focus on the chronic phase, when wild-type (Lgals3+/+) and Lgals3-/- mice were analyzed 90 days after cercariae infection. In Lgals3-/- infected mice, there was significant inflammatory infiltration with myeloid cells associated with egg destruction (hematoxylin and eosin staining), phagocytes (specifically Kupffer cells), numerically reduced and diffuse matrix extracellular deposition in fibrotic areas (Gomori trichrome staining), and severe disorganization of collagen fibers surrounding the S. mansoni eggs (reticulin staining). Granuloma-derived stromal cells (GR cells) of Lgals3-/- infected mice expressed lower levels of alpha smooth muscle actin (α-SMA) and eotaxin and higher levels of IL-4 than Lgals3+/+ mice (real-time PCR). The relevant participation of macrophages in these events led us to suggest distinct mechanisms of activation that culminate in defective fibrosis in the liver of Lgals3-/- infected mice. These aspects were discussed in this review, as well as the possible interference between Gal-3, HDACs, and Hh signaling during progressive liver fibrosis in S. mansoni-infected mice. Further studies focused on macrophage roles could elucidate these questions and clear the potential utility of these molecules as antifibrotic targets

    Síndrome do desfiladeiro cérvico torácico: relato de caso

    Get PDF
    A Síndrome do Desfiladeiro Cérvico Torácico (SDCT) é uma entidade clínica com sintomatologia diversa, decorrente de compressão anormal do plexo braquial, na região do desfiladeiro torácico. Esta compressão é exercida, na maioria das vezes, pelo músculo escaleno anterior, mas pode resultar também da existência de bandas musculofibróticas, alteração da morfologia da primeira costela, costelas cervicais e músculos anômalos. A SDCT pode ser classificada nos tipos arterial, venoso e neurogênico.  Neste trabalho, relatamos dois casos de pacientes com sintomatologia e presença de costela cervical que foram operadas e tiveram resultado satisfatório. A SDCT acomete mais mulheres entre 20-50 anos, com vários fatores contribuintes, chegando a limitar as atividades diárias e laborais. O tratamento clínico, frequentemente, é a conduta inicial, com o objetivo de aliviar os sintomas. Em geral, o tratamento cirúrgico tem indicação em alguns casos dependendo da sua apresentação. Apesar da SDCT ser uma condição rara, é importante considerá-la no diagnóstico diferencial de pacientes com queixas de dor e parestesias em membros superiores

    Microalgae biomass as an alternative ingredient in cookies: sensory, physical and chemical properties, antioxidant activity and in vitro digestibility

    Get PDF
    Microalgae can be regarded as an alternative and promising food ingredient due to their nutritional composition, richness in bioactive compounds, and because they are considered a sustainable protein source for the future. The aim of this work was to evaluate microalgae (Arthrospira platensis F & M-C256, Chlorella vulgaris Allma, Tetraselmis suecica F & M-M33 and Phaeodactylum tricornutum F & M-M40) as innovative ingredients to enhance functional properties of cookies. Two biomass levels were tested and compared to control: 2% (w/w) and 6% (w/ w), to provide high levels of algae-bioactives. The cookies sensory and physical properties were evaluated during eight weeks showing high color and texture stability. Cookies prepared with A. platensis and C. vulgaris presented significantly (p < 0.05) higher protein content compared to the control, and by sensory analysis A. platensis cookies were preferred. Besides, A. platensis also provided a structuring effect in terms of cookies texture. All microalgae-based cookies showed significantly higher (p < 0.05) total phenolic content and in vitro antioxidant capacity compared to the control. No significant difference (p < 0.05) in in vitro digestibility between microalgae cookies and the control was foundinfo:eu-repo/semantics/publishedVersio

    Growth, sensory and chemical characterization of Mediterranean yellowtail (Seriola dumerili) fed diets with partial replacement of fish meal by other protein sources

    [EN] An 84-day trial was performed to assess the use of alternative protein sources in Seriola dumerili. Three diets were used, FM100 diet, as a control diet without fishmeal substitution, and FM66 and FM33 diets with a fishmeal replacement of 330 g/kg and 660 g/kg, respectively. At the end of experiment, fish fed the FM66 diet showed the no differences in growth, nutritional parameters and fatty acid composition. Heavy metals present some differences but are always lower than risk levels. In sensory analysis, differences between diets appeared in pH and color, and also in some texture parameters between FM33 and the other two diets. No differences appeared between diets related to flavor. In summary, long periods of feeding with high fish meal substitution diets, affects Seriola dumerili growth; despite this the quality of the fillet was not affected even with a 66 % of substitution.This project was financed by "Generalitat Valenciana.

    Prevalence of human T-lymphotropic virus type 1 and 2 among blood donors in Manaus, Amazonas State, Brazil

    Get PDF
    Introduction: Human T-lymphotropic virus type 1 and 2 (HTLV-1/2) is endemic in Brazil, but few studies have investigated the seroprevalence of HTLV and its subtypes among blood donors in the capital city Manaus, Amazonas State, Brazil. Aim: To estimate the seroprevalence of HTLV-1/2 and to identify circulating subtypes among blood donors in Manaus. Materials and Methods: Blood donors (2001-2003) were screened for HTLV-1/2 antibodies by ELISA. Positive results were confirmed and subtyped by Western blot assays. Prevalence rates were calculated and compared with demographic data. Results: Among the 87,402 individuals screened, 116 (0.13%) were seropositive for HTLV-1/2. A second sample (76/116) was collected and retested by HTLV-1/2 ELISA, of which only 41/76 were positive. Western blot confirmed HTLV infection in 24/41 retested blood donors [HTLV-1 (n=16), HTLV-2 (n=5) and HTLV-untypable (n=3)]. Discussion: HTLV-1 and HTLV-2 are prevalent among blood donors in Manaus. However, additional studies are needed to comprehend the epidemiology of HTLV-1/2 in Amazonas not only to understand the pathophysiology of the disease providing adequate medical assistance, but also to reduce or block virus transmission. © 2017, Instituto de Medicina Tropical de Sao Paulo.

    The aim of this study is to disassemble, through scientific articles and government exposure, the main concepts related to electric shock injury. And as secondary objectives, to address a perspective of adequate treatment in this scenario and surgical steps in the management of patients traumatized by electric shock. An in-depth search of articles was carried out in the Scientific Electronic Library Online (SciELO) and PubMed databases, with the following Health Sciences Descriptors (DeCS):Electric burns; Shock; Debridement; Hydration; Amputation. Articles were selected between the periods of 2000 to 2023, in Portuguese, to increase the level of relevance and quality of the review, given the scarcity of scientific studies on the subject. It is concluded with the analysis of these studies that the early medical intervention of an electrical trauma is essential. The correct management, before 15 days, can positively corroborate the survival rates of these patients, avoiding possible complications. However, the proportion of the accident can affect medical management, representing a problem for patients, attributing greater symptoms.El objetivo de este estudio es desmontar, a través de artículos científicos y exposición gubernamental, los principales conceptos relacionados con la lesión por descarga eléctrica.

Se realizó una búsqueda exhaustiva de artículos en las bases de datos Scientific Electronic Library Online (SciELO) y PubMed, con los siguientes Descriptores en Ciencias de la Salud (DeCS): Quemaduras eléctricas; Choque; desbridamiento; Hidratación; Amputación. Los artículos fueron seleccionados entre los períodos de 2000 a 2023, en portugués, para aumentar el nivel de relevancia y calidad de la revisión, dada la escasez de estudios científicos sobre el tema. Se concluye con el análisis de estos estudios que la intervención médica temprana de un trauma eléctrico es fundamental. El correcto manejo, antes de los 15 días, puede corroborar positivamente las tasas de supervivencia de estos pacientes, evitando posibles complicaciones. Sin embargo, la proporción del accidente puede afectar el manejo médico, representando un problema para los pacientes, atribuyéndoles mayor sintomatología.Objetivo desse estudo é desmontar, por meio de artigos científicos e exposição governamentais, os principais conceitos que tangem a lesão por choque elétrico.

    The aim of this work was to evaluate the influence of Arthrospira platensis F&M-C256 (spirulina) incorporation on the nutritional and functional properties of “crostini”, a leavened bakery product largely consumed in Italy and Europe. Sourdough was used as leavening and fermentation agent and three concentrations of A. platensis F&M-C256 were tested: 2%, 6% and 10% (w/w). Despite a lower volume increase compared to the control, the A. platensis F&M-C256 “crostini” doughs reached a technological appropriate volume after fermentation. At the end of fermentation, no significant differences in microorganisms concentrations were observed. A. platensis F&M-C256 “crostini” showed higher protein content compared to the control. Considering the European Commission Regulation on nutritional claims, “crostini” incorporated with 6% and 10% biomass can be claimed to be a “source of protein”. Six and ten percent A. platensis “crostini” also presented significantly higher antioxidant capacity and phenolics. A significantly lower value of in vitro dry matter and protein digestibility between A. platensis F&M-C256 “crostini” and the control was found. The overall acceptability decreased with increasing A. platensis F&M-C256 addition. The combination of spirulina biomass addition and the sourdough technology led to the development of a novel microalgae-based bakery product with nutritional and functional featuresinfo:eu-repo/semantics/publishedVersio
