1Effects of Saccharomycesboulardiion fecal short-chain fatty acids and microflora in patients on long-term total enteral nutrition显示文摘AIM: To assess the effects of Sb on fecal flora and shortchain fatty acids (SCFA) in patients on long-term TEN.METHODS: Ten patients (3 females, 7 males, 59±5.5 years),on TEN for a median of 13 mo (1-125), and 15 healthy volunteers (4 females, 11 males, 32±2.0 years) received Sb (0.5 g bid PO) for 6 d. Two stool samples were taken before, on the last 2 d and 9-10 d after treatment, for SCFA measurement and for culture and bacterial identification.Values (mean±SE) were compared using sign tests and ANOVA.RESULTS: Fecal butyrate levels were lower in patients(10.1±2.9 mmol/kg) than in controls (19.2±3.9, P= 0.02).Treatment with Sb increased total fecal SCFA levels in patients (150.2±27.2 vs 107.5±18.2 mmol/kg, P = 0.02)but not in controls (129.0±28.6 vs 113.0±15.2 mmol/kg,NS). At the end of treatment with Sb, patients had higher fecal butyrate (16.0±4.4 vs 10.1 [2.9] mmol/kg, P = 0.004).Total SCFAs remained high 9 d after treatment was discontinued. Before the treatment, the anaerobe to aerobe ratio was lower in patients compared to controls (2.4±2.3 vs69.8±1.8, P = 0.003). There were no significant changes in the fecal flora of TEN patients.CONCLUSION: Sb-induced increase of fecal SCFA concentrations (especially butyrate) may explain the preventive effects of this yeast on TEN-induced diarrhea.Stéphane M Schneider Fernand Girard-Pipau Jér(o|^)me Filippi Xavier Hébuterne Dominique Moyse Gustavo Calle Hinojosa Anne Pompei Patrick Rampal 2005World Journal of Gastroenterology2005,11,39:26
2Cardiac biomarkers in pediatric heart disease:A state of art review显示文摘Every year there are more than 11000 hospitalizations related to heart failure in children resulting in significant morbidity and mortality.Over the last two decades,our understanding,diagnosis and management of pediatric heart failure is evolving but our ability to prognosticate outcomes in pediatric heart acute heart failure is extremely limited due to lack of data.In adult heart failure patients,the role of cardiac biomarkers has exponentially increased over the last two decades.Current guidelines for management of heart failure emphasize the role of cardiac biomarkers in diagnosis,management and prognostication of heart failure.It is also noteworthy that these biomarkers reflect important biological processes that also open up the possibility of therapeutic targets.There is however,a significant gap present in the pediatric population with regards to biomarkers in pediatric heart failure.Here,we seek to review available data regarding cardiac biomarkers in the pediatric population and also explore some of the emerging biomarkers from adult literature that may be pertinent to pediatric heart failure.Benedict A Fernandes Kevin O Maher Shriprasad R Deshpande 2016World Journal of Cardiology2016,8,12:6
3Understanding plant drought resistance in a Mediterranean coastal sand dune ecosystem:differences between native and exotic invasive species显示文摘Aims Mediterranean coastal dunes are habitats of great conservation interest,with a distinctive and rich flora.In the last century,Acacia spp.,native from Australia,have been introduced in Portugal,with the objective of stabilizing sand dunes,and since have become dominant in numerous sand dune habitats.This invasion process led to the reduction of native plant species richness,changed soil characteristics and modified habitat’s microclimatic char-acteristics.The aim of this research was to typify and compare,in Mediterranean sand dune ecosystems,the ecophysiological responses to drought of Helichrysum italicum and Corema album,two native species,and Acacia longifolia,an exotic invasive spe-cies.We addressed the following specific objectives:(i)to com-pare water relations and water use efficiencies,(ii)to evaluate water stress,(iii)to assess water use strategies and water sources used by plants and(iv)to evaluate the morphological adaptations at leaf and phyllode level.Methods In order to obtain an integrative view of ecophysiological patterns,water relations and performance measuring methods have been applied:predawn(ψPD)and midday(ψMD)water potential,chloro-phyll a fluorescence,oxygen isotopic composition of xylem,rain and groundwater(δ18O)and leaf carbon isotopic discrimination(Δ13C).The leaf characteristics of the three species,as well as the histochemistry of non-glandular trichome cell walls,were also studied to identify morpho-traits related to drought resistance.Important Findings The results support our initial hypothesis:although A.longifolia clearly possesses a degree of resistance to water stress,such ability is provided by a different water strategy,when compared to native species.Natives relied on morphological adaptations to restrict water loss,whereas the invasive species adjusted the water uptake as a way to balance their limited ability of restricting water loss.We corroborate that woody native species(i)have a conservative water-saving strategy and minor seasonal variations relative to invasive species,(ii)use enriched water sources during drought periods,indicating different water sources and root systems com-paring with invasive species and(iii)present drought leaf morpho-functional adaptations related with limiting water loss.Comparing the physiological performance of invasive and native species can offer causal explanations for the relative success of alien plant invasions on sand dunes ecosystems.Cristina Antunes Ana Júlia Pereira Patrícia Fernandes Margarida Ramos Lia Ascensão Otília Correia Cristina Máguas 2018Journal of Plant Ecology2018,11,1:4
4Effect of sewage sludge and sugarcane bagasse biochar on soil properties and sugar beet production显示文摘Recently, biochar has shown to be an alternative to waste disposal and a source of nutrients, acting as a soil amendment. The effects of two types of biochar on soil properties and sugar beet production as well as potential for carbon(C) sequestration were evaluated: biochar produced from sewage sludge(SB) and biochar produced from a 1:1 mixture of sewage sludge and sugarcane bagasse(MB). A greenhouse pot experiment was conducted using a sandy loam soil from the Brazilian savanna under treatments of MB applications at 2.5%, 5.0%, 7.5%, and 10.0%, SB application at 5.0%, and a conventional fertilization(CF) using lime and mineral fertilizers, with no fertilization as a control. After incubation for 45 d, seedlings were transplanted into each pot and cultivated for 55 d. Biochar characterization showed that pyrolysis reduced the biomass volume drastically, but concentrated the trace elements per unit of biochar weight. The MB treatments increased soil total C(by 27.8%) and pH(by 0.6), reduced the concentrations of nutrients, except for potassium(K), and chromium(Cr), and did not significantly alter lead(Pb) and cadmium(Cd) concentrations. Results of stable isotopes showed that all biochar treatments increased the total soil C stock and stability, suggesting a potential for application in C sequestration, and improved overall soil fertility. However, the biochar treatments also increased the concentrations of trace elements in the soil and plants. The sugar beet yields at 10.0% MB and 5.0% SB corresponded to 55%and 29% of the yield obtained in the CF treatment, respectively. These results may be due to biochar nutrients not being bioavailable when required by plants or to biochar nutrient adsorption.Barbara Samartini Queiroz ALVES Katherin Prissila Sevilla ZELAYA Fernando COLEN Ledivan Almeida FRAZÃO Alfredo NAPOLI Sanjai J.PARIKH Luiz Arnaldo FERNANDES 2021Pedosphere2021,31,4:4
5Quality of life, work productivity impairment and healthcare resources in inflammatory bowel diseases in Brazil显示文摘BACKGROUND Inflammatory bowel diseases(IBD)have been associated with a low quality of life(QoL)and a negative impact on work productivity compared to the general population.Information about disease control,patient-reported outcomes(PROs),treatment patterns and use of healthcare resources is relevant to optimizing IBD management.AIM To describe QoL and work productivity and activity impairment(WPAI),treatment patterns and use of healthcare resources among IBD patients in Brazil.METHODS A multicenter cross-sectional study included adult outpatients who were previously diagnosed with moderate to severe Crohn’s disease(CD)or ulcerative colitis(UC).At enrolment,active CD and UC were defined as having a Harvey Bradshaw Index≥8 or a CD Activity Index≥220 or calprotectin>200μg/g or previous colonoscopy results suggestive of inadequate control(per investigator criteria)and a 9-point partial Mayo score≥5,respectively.The PRO assessment included the QoL questionnaires SF-36 and EQ-5D-5L,the Inflammatory Bowel Disease Questionnaire(IBDQ),and the WPAI questionnaire.Information about healthcare resources and treatment during the previous 3 years was collected from medical records.Chi-square,Fisher’s exact and Student’s t-/Mann-Whitney U tests were used to compare PROs,treatment patterns and the use of healthcare resources by disease activity(α=0.05).RESULTS Of the 407 patients in this study(CD/UC:64.9%/35.1%,mean age 42.9/45.9 years,54.2%/56.6%female,38.3%/37.1%employed),44.7%/25.2%presented moderate-to-severe CD/UC activity,respectively,at baseline.Expressed in median values for CD/UC,respectively,the SF-36 physical component was 46.6/44.7 and the mental component was 45.2/44.2,the EQ-visual analog scale score was 80.0/70.0,and the IBDQ overall score was 164.0/165.0.Moderate to severe activity,female gender,being unemployed,a lower educational level and lower income were associated with lower QoL(P<0.05).Median work productivity impairment was 20%and 5%for CD and UC patients,respectively,and activity impairment was 30%,the latter being higher among patients with moderate to severe disease activity compared to patients with mild or no disease activity(75.0%vs 10.0%,P<0.001).For CD/UC patients,respectively,25.4%/2.8%had at least one surgery,38.3%/19.6%were hospitalized,and 70.7%/77.6%changed IBD treatment at least once during the last 3 years.The most common treatments at baseline were biologics(75.3%)and immunosuppressants(70.9%)for CD patients and 5-ASA compounds(77.5%)for UC patients.CONCLUSION Moderate to severe IBD activity,especially among CD patients,is associated with a substantial impact on QoL,work productivity impairment and an increased number of IBD surgeries and hospitalizations in Brazil.Rogerio Serafim Parra Julio MF Chebli Heda MBS Amarante Cristina Flores Jose ML Parente Odery Ramos Milene Fernandes Jose JR Rocha Marley R Feitosa Omar Feres Antonio S Scotton Rodrigo B Nones Murilo M Lima Cyrla Zaltman Carolina D Goncalves Isabella M Guimaraes Genoile O Santana Ligia Y Sassaki Rogerio S Hossne Mauro Bafutto Roberto LK Junior Mikaell AG Faria Sender J Miszputen Tarcia NF Gomes Wilson R Catapani Anderson A Faria Stella CS Souza Rosana F Caratin Juliana T Senra Maria LA Ferrari 2019World Journal of Gastroenterology2019,25,38:2

7Clinical hematological and biochemical parameters in Swiss,BALB/c,C57BL/6 and B6D2F1 Mus musculus显示文摘Background:Animal models are widely used in scientific research in order to obtain information from a whole organism under a specific set of experimental conditions.Various lineages of mice have been used to investigate diseases and new therapeutic strategies,and,consequently,hematological and biochemical tests in these laboratory animals are essential to validate scientific studies.Our study seeks to establish reference values for hematological and biochemical parameters of four lineages of mice.Methods:We evaluated the hematological and biochemical profiles of 20 males and 20 females from the lineages Swiss(heterogeneous),BALB/c and C57BL/6(isogenic),and B6D2F1(hybrid),totaling 160 mice.Analysis were standardized using the systems pocH-100iV Diff™for 19 hematological parameters and VITROS®350 for 12 biochemical parameters.Results:Results are shown as means and standard deviation,grouped by lineage and genre.Comparing the values obtained in this study with the values from previous studies,some variations were detected,which could be explained by differences in methodologies or individual variability.Conclusion:Thus our study shows that knowledge and disclosure of the values of physiological parameters of laboratory animals is necessary,and emphasises the importance of considering variations influenced by gender,lineage and genotype in the choice of the best experimental model.Giorgio Silva-Santana Juliet Cunha Bax Débora Cristina Silva Fernandes Daniela Tendler Leibel Bacellar Cleber Hooper Alexandre Alves Souza Oliveira Dias Cristina Barbosa Silva Aline Moreira de Souza Simone Ramos Ricardo Alexandre Santos Thainara Ramos Pinto Mariana Antunes Ramão Ana Luíza Mattos-Guaraldi 2020Animal Models and Experimental Medicine2020,3,4:2

9NT157 has antineoplastic effects and inhibits IRS1/2 and STAT3/5 in JAK2^(V617F)-positive myeloproliferative neoplasm cells显示文摘Recent data indicate that IGF1R/IRS signaling is a potential therapeutic target in BCR-ABL1-negative myeloproliferative neoplasms(MPN);in this pathway,IRS2 is involved in the malignant transformation induced by JAK2^(V617F),and upregulation of IGF1R signaling induces the MPN phenotype.NT157,a synthetic compound designed as an IGF1R-IRS1/2 inhibitor,has been shown to induce antineoplastic effects in solid tumors.Herein,we aimed to characterize the molecular and cellular effects of NT157 in JAK2^(V617F)positive MPN cell lines(HEL and SET2)and primary patient hematopoietic cells.In JAK2^(V617F)cell lines,NT157 decreased cell viability,clonogenicity,and cell proliferation,resulting in increases in apoptosis and cell cycle arrest in the G2/M phase(p<0.05).NT157 treatment inhibited IRS1/2,JAK2/STAT,and NFκB signaling,and it activated the AP-1 complex,downregulated four oncogenes(CCND1,MYB,WT1,and NFKB1),and upregulated three apoptotic-related genes(CDKN1A,FOS,and JUN)(p<0.05).NT157 induced genotoxic stress in a JAK2/STAT-independent manner.NT157 inhibited erythropoietin-independent colony formation in cells from polycythemia vera patients(p<0.05).These findings further elucidate the mechanism of NT157 action in a MPN context and suggest that targeting IRS1/2 proteins may represent a promising therapeutic strategy for MPN.Bruna Alves Fenerich Jaqueline Cristina Fernandes Ana Paula Nunes Rodrigues Alves Juan Luiz Coelho-Silva Renata Scopim-Ribeiro Priscila Santos Scheucher Christopher A.Eide Cristina E.Tognon Brian J.Druker Eduardo Magalhães Rego João Agostinho Machado-Neto Fabiola Traina 2020Signal Transduction and Targeted Therapy2020,5,1:2
