| 1 | Prognostic value of increased carbohydrate antigen in patients with heart failure显示文摘AIM:To study the prognostic value of carbohydrateantigen 125(CA125) and whether it adds prognostic information to N-terminal pro-brain natriuretic peptide(NT-proBNP) in stable heart failure(HF) patients.METHODS:The predictive value of CA125 was retrospectively assessed in 156 patients with stable HF remitted to the outpatient HF unit for monitoring from 2009 to 2011.Patients were included in the study if they had a previous documented episode of HF and received HF treatment.CA125 and NT-proBNP concentrations were measured.The independent association between NT-proBNP or CA125 and mortality was assessed with Cox regression analysis,and their combined predictive ability was tested by the integrated discrimination improvement(IDI) index.RESULTS:The mean age of the 156 patients was 72 ± 12 years.During follow-up(17 ± 8 mo),27 patients died,1 received an urgent heart transplantation and 106 required hospitalization for HF.Higher CA125 values were correlated with outcomes:58 ± 85 KU/L if hospitalized vs 34 ± 61 KU/L if not(P < 0.05),and 94 ± 121 KU/L in those who died or needed urgent heart transplantation vs 45 ± 78 KU/L in survivors(P < 0.01).After adjusting for propensity scores,the highest risk was observed when both biomarkers were elevated vs not elevated(HR = 8.95,95%CI:3.11-25.73; P < 0.001) and intermediate when only NT-proBNP was elevated vs not elevated(HR = 4.15,95%CI:1.41-12.24; P < 0.01).Moreover,when CA125 was added to the clinical model with NT-proBNP,a 4%(P < 0.05) improvement in the IDI was found.CONCLUSION:CA125 > 60 KU/L identified patients in stable HF with poor survival.Circulating CA125 level adds prognostic value to NT-proBNP level in predicting HF outcomes. | Ana B Méndez Jordi Ordonez-Llanos Andreu Ferrero Mariana Noguero Teresa Mir Josefina Mora Antoni Bayes-Genis Sònia Mirabet Juan Cinca Eulàlia Roig | 2014 | World Journal of Cardiology2014，6，4： | 13 |
| 2 | Gut-brain connection: The neuroprotective effects of the anti-diabetic drug liraglutide显示文摘Long-acting glucagon-like peptide-1(GLP-1) analogues marketed for type 2 diabetes(T2D) treatment have been showing positive and protective effects in several different tissues, including pancreas, heart or even brain. This gut secreted hormone plays a potent insulinotropic activity and an important role in maintaining glucose homeostasis. Furthermore, growing evidences suggest the occurrence of several commonalities between T2 D and neurodegenerative diseases, insulin resistance being pointed as a main cause for cognitive decline and increased risk to develop dementia. In this regard, it has also been suggested that stimulation of brain insulin signaling may have a protective role against cognitive deficits. As GLP-1 receptors(GLP-1R) are expressed throughout the central nervous system and GLP-1 may cross the blood-brain-barrier, an emerging hypothesis suggests that they may be promising therapeutic targets against brain dysfunctional insulin signaling-related pathologies. Importantly, GLP-1 actions depend not only on the direct effect mediated by its receptor activation, but also on the gut-brain axis involving an exchange of signals between both tissues via the vagal nerve, thereby regulating numerous physiological functions(e.g., energy homeostasis, glucose-dependent insulin secretion, as well as appetite and weight control). Amongst the incretin/GLP-1 mimetics class of anti-T2 D drugs with an increasingly described neuroprotective potential, the already marketed liraglutide emerged as a GLP-1R agonist highly resistant to dipeptidyl peptidase-4 degradation(thereby having an increased half-life) and whose systemic GLP-1R activity is comparable to that of native GLP-1. Importantly, several preclinical studies showed anti-apoptotic, anti-inflammatory, anti-oxidant and neuroprotective effects of liraglutide against T2 D, stroke and Alzheimer disease(AD), whereas several clinical trials, demonstrated some surprising benefits of liraglutide on weight loss, microglia inhibition, behavior and cognition, and in AD biomarkers. Herein, we discuss the GLP-1 action through the gut-brain axis, the hormone's regulation of some autonomic functions and liraglutide's neuroprotective potential. | Emanuel Monteiro Candeias Inês Carolina Sebastio Susana Maria Cardoso Sónia Catarina Correia Cristina Isabel Carvalho Ana Isabel Plácido Maria Sancha Santos Catarina Resende Oliveira Paula Isabel Moreira Ana Isabel Duarte | 2015 | World Journal of Diabetes2015，6，6： | 9 |
| 3 | Primary malignant melanoma of the esophagus:A case report显示文摘The authors present the clinical case of an 87-year-old Caucasian male admitted to the emergency room with hematemesis. He had a history of intermittent dys-phagia during the previous month. Endoscopic evaluation revealed an eccentric,soft esophageal lesionlocated 25-35 cm from the incisors,which appeared asa protrusion of the esophagus wall,with active bleeding. Biopsies were acquired. Tissue evaluation wascompatible with a melanoma. After excluding other sites of primary neoplasm,the definitive diagnosis of Primary Malignant Melanoma of the Esophagus(PMME) was made. The patient developed a hospital-acquired respiratory infection and died before tumor-directed treatment could begin. Primary malignant melanoma represents only 0.1% to 0.2% of all esophageal ma-lignant tumors. Risk factors for PMME are not defined.A higher incidence of PMME has been described in Japan. Dysphagia,predominantly for solids,is the most frequent symptom at presentation. Retrosternal orepigastric discom fort or pain,melena or hemate mesishave also been described. The characteristic endoscopic finding of PMME is as a polypoid lesion,with variablesize,usually pigmented. The neoplasm occurs in thelower two-thirds of the esophagus in 86% of cases.PMME metastasizes via hematogenic and lymphatic pathways. At diagnosis,50% of the patients present with distant metastases to the liver,the mediastinum,the lungs and the brain. When possible,surgery(curative or palliative) ,is the preferential method of treatment. There are some reports in the literature where chemotherapy,chemohormon otherapy,radiotherapy and immunotherapy,with or without surgery,wereused with variable efficacy. The prognosis is poor;themean survival after surgery is less than 15 mo. | Joana Machado Paula Ministro Ricardo Araújo Eugénia Cancela António Castanheira Américo Silva | 2011 | World Journal of Gastroenterology2011，17，42： | 6 |
| 4 | Bone marrow-derived monocyte infusion improves hepatic fibrosis by decreasing osteopontin,TGF-β1,IL-13 and oxidative stress显示文摘AIM To evaluate the therapeutic effects of bone marrowderived CD11b+CD14+ monocytes in a murine model of chronic liver damage. METHODS Chronic liver damage was induced in C57BL/6 mice by administration of carbon tetrachloride and ethanol for 6 mo. Bone marrow-derived monocytes isolated by immunomagnetic separation were used for therapy. The cell transplantation effects were evaluated by morphometry,biochemical assessment,immunohistochemistry and enzyme-linked immunosorbent assay. RESULTS CD11b+CD14+ monocyte therapy significantly reduced liver fibrosis and increased hepatic glutathione levels. Levels of pro-inflammatory cytokines,including tumor necrosis factor-α,interleukin(IL)-6 and IL-1β,in addition to pro-fibrotic factors,such as IL-13,transforming growth factor-β1 and tissue inhibitor of metalloproteinase-1 also decreased,while IL-10 and matrix metalloproteinase-9 increased in the monocytetreated group. CD11b+CD14+ monocyte transplantation caused significant changes in the hepatic expression of α-smooth muscle actin and osteopontin. CONCLUSION Monocyte therapy is capable of bringing about improvement of liver fibrosis by reducing oxidative stress and inflammation,as well as increasing antifibrogenic factors. | Veruska Cintia Alexandrino de Souza Thiago Almeida Pereira Valéria Wanderley Teixeira Helotonio Carvalho Maria Carolina Accioly Brelaz de Castro Carolline Guimaraes D’assuncao Andreia Ferreira de Barros Camila Lima Carvalho Virgínia Maria Barros de Lorena Vláudia Maria Assis Costa Alvaro Aguiar Coelho Teixeira Regina Celia Bressan Queiroz Figueiredo Sheilla Andrade de Oliveira | 2017 | World Journal of Gastroenterology2017，23，28： | 6 |
| 5 | Impaired T-cell differentiation in diabetic foot ulceration显示文摘Foot ulceration is one of the most debilitating complications associated with diabetes,but its cause remains poorly understood.Several studies have been undertaken to understand healing kinetics or find possible therapies to enhance healing.However,few studies have been directed at understanding the immunological alterations that could influence wound healing in diabetes.In this study,we analysed the T-cell receptor(TCR)repertoire diversity in TCR-αβ^(+)T cells.We also analysed the distribution and phenotype of T cells obtained from the peripheral blood of healthy controls and diabetic individuals with or without foot ulcers.Our results showed that diabetic individuals,especially those with foot ulcers,have a significantly lower naive T-cell number and a poorer TCR-Vβrepertoire diversity.We also showed that the reduced TCR-Vβrepertoire diversity in diabetic individuals was mainly owing to the accumulation of effector T cells,the major source of tumour necrosis factor-αproduction,which was even more pronounced in patients with acute foot ulceration.Moreover,the expression of several inflammatory chemokine receptors was significantly reduced in diabetic patients.In conclusion,effector T-cell accumulation and TCR repertoire diversity reduction appear to precede the development of foot ulcers.This finding may open new immunological therapeutic possibilities and provide a new prognostic tool in diabetic wound care. | João Moura João Rodrigues Marta Gonçalves Cláudia Amaral Margarida Lima Eugénia Carvalho | 2017 | Cellular & Molecular Immunology2017，14，9： | 6 |
| 6 | Effectiveness of an intervention for reducing social stigma towards mental illness in adolescents显示文摘AIM: To evaluate the effectiveness of an intervention for reducing social stigma towards mental illness in adolescents. The effect of gender and knowledge of someone with mental illness was measured. METHODS: Two hundred and eighty secondary school students were evaluated using the Community Attitudes towards Mental Illness(CAMI) questionnaire. The schools were randomized and some received the intervention and others acted as the control group. The programme consisted of providing information via a documentary film and of contact with healthcare staff in order to reduce the social stigma within the school environment. RESULTS: The intervention was effective in reducing the CAMI authoritarianism and social restrictiveness subscales. The intervention showed significant changes in girls in terms of authoritarianism and social restrictiveness, while boys only showed significant changes in authoritarianism. Following the intervention, a significant reduction was found in authoritarianism and social restrictiveness in those who knew someone with mental illness, and only in authoritarianism in those who did not know anyone with mental illness. CONCLUSION: The intervention was effective to reduce social stigma towards people with mental illness, especially in the area of authoritarianism. Some differences were found depending on gender and whether or not the subjects knew someone with mental illness. | Regina Vila-Badia Francisco Martínez-Zambrano Otilia Arenas Emma Casas-Anguera Esther García-Morales Raúl Villellas José Ramón Martín María Belén Pérez-Franco Tamara Valduciel Diana Casellas Mar García-Franco Jose Miguel Joaquim Balsera Gemma Pascual Eugènia Julia Susana Ochoa | 2016 | World Journal of Psychiatry2016，6，2： | 4 |

| 8 | Assessing the relationship between the rumen microbiota and feed efficiency in Nellore steers显示文摘Background:Ruminants rely upon a complex community of microbes in their rumen to convert host-indigestible feed into nutrients.However,little is known about the association between the rumen microbiota and feed efficiency traits in Nellore(Bos indicus)cattle,a breed of major economic importance to the global beef market.Here,we compare the composition of the bacterial,archaeal and fungal communities in the rumen of Nellore steers with high and low feed efficiency(FE)phenotypes,as measured by residual feed intake(RFI).Results:The Firmicutes to Bacteroidetes ratio was significantly higher(P<0.05)in positive-RFI steers(p-RFI,low feed efficiency)than in negative-RFI(n-RFI,high feed efficiency)steers.The differences in bacterial composition from steers with high and low FE were mainly associated with members of the families Lachnospiraceae,Ruminococcaceae and Christensenellaceae,as well as the genus Prevotella.Archaeal community richness was lower(P<0.05)in p-RFI than in n-RFI steers and the genus Methanobrevibacter was either increased or exclusive of p-RFI steers.The fungal genus Buwchfawromyces was more abundant in the rumen solid fraction of n-RFI steers(P<0.05)and a highly abundant OTU belonging to the genus Piromyces was also increased in the rumen microbiota of highefficiency steers.However,analysis of rumen fermentation variables and functional predictions indicated similar metabolic outputs for the microbiota of distinct FE groups.Conclusions:Our results demonstrate that differences in the ruminal microbiota of high and low FE Nellore steers comprise specific taxa from the bacterial,archaeal and fungal communities.Biomarker OTUs belonging to the genus Piromyces were identified in animals showing high feed efficiency,whereas among archaea,Methanobrevibacter was associated with steers classified as p-RFI.The identification of specific RFI-associated microorganisms in Nellore steers could guide further studies targeting the isolation and functional characterization of rumen microbes potentially important for the energy-harvesting efficiency of ruminants. | Déborah Romaskevis Gomes Lopes Márcio de Souza Duarte Alex J.La Reau Ibrahim Zuniga Chaves Tiago Antônio de Oliveira Mendes Edenio Detmann Cláudia Braga Pereira Bento Maria Eugênia Zerlotti Mercadante Sarah Figueiredo Martins Bonilha Garret Suen Hilário Cuquetto Mantovani | 2021 | Journal of Animal Science and Biotechnology2021，12，4： | 3 |
| 9 | Quantitative scintigraphic analysis of the apical seal in Thermafil/Topseal and Real Seal 1/Realseal filled root canals显示文摘AIM: To investigate the microleakage of two different root canal obturation systems, using the nuclear medicine approach.METHODS: Twenty-six single-rooted extracted teeth were selected. The crowns were sectioned to obtain 15-mm long root segments and each tooth was prepared using rotary Pro File instruments. The roots were divided into 2 experimental groups using Real Seal 1 and Real Seal sealer or Thermafil and Top Seal sealer as well as two control groups. On the 7th and the 28 th day the apices were submersed in a solution of 99 m TcPertechnetate during 3 h. The radioactivity was counted using a γ camera. RESULTS: The present study showed that none of the root canal-filled teeth was leakage free. The statistical analyses were made using Kruskal-Wallis and statistical significance was assessed using α = 0.05. Although apical leakage measured in counts per minute(cpm) in the Thermafil/Top Seal group was lower than in the Real Seal/Real Seal group(363 916 ± 180 707.7 cpm vs533 427 ± 414 020.6 cpm) on 7th day and(1 678 200 ± 567 217.4 cpm vs 2 240 518 ± 383 356.7 cpm) on 28 th day, there was no statistical difference(P > 0.05). In the Thermafil/Top Seal group and Real Seal 1/Real Seal group it was found that over time, the number of counts increased between 7 d and 28 d(363 916 ± 180 707.7 cpm vs 1 678 200 ± 567 217.4 cpm) and(533 427 ± 414 020.6 cpm vs 2 240 518 ± 383 356.7 cpm), respectively, with statistically significant differences(Thermafil/Top Seal group, P = 0.015 and Real Seal 1/Real Seal group, P = 0.036).CONCLUSION:Both carrier-based Realseal 1 and Thermafil techniques showed a similar sealing effect,but none of the materials was leakage free. | Manuel Marques Ferreira Margarida Abrantes Eunice Virgínia Carrilho Maria Filomena Botelho | 2013 | World Journal of Stomatology2013，2，2： | 2 |

| 11 | 金龟子绿僵菌分生孢子暴露在B段紫外光下毒力的降低显示文摘The UV-A and UV-B wavelengths of solar radiation may seriously reduce viability of Metarhizium anisopliae conidia,a fungus used extensively in Brazil for insect pest control.The conidial tolerances to UV-A and UV-B radiation were studied for one isolate(IBCB 425) commercially available product produced on rice grains.Aqueous or oil emulsion conidial suspensions were irradiated for 0(control),2,or 3 h using the solar simulator filtered with diacetate filter to remove UV-C radiation which afforded 652 mW·m-2 in the spectral range of 280~370 nm.The UV tolerance was based on conidial germination(viability) and virulence to Diatraea saccharalis larvae.Conidia formulated with oil emulsion had higher survival after 3 h of UV exposure,but the virulence of the conidia previously exposed to 2 h of UV radiation were similar when oil formulated or not.The mortality of D.saccharalis caterpillars exposed to non-UV-irradiated conidia was greater than that of larvae exposed to irradiated conidia,and the LT50 values were lower for the non-irradiated suspensions than for those irradiated.This apparent reduction in virulence was directly related reduction in viability or delay of germination of UV-irradiated conidia. | Edimara A Francisco Drauzio E N Rangel Newton La Scala Jr José C Barbosa Antnia do C B Correia | 2008 | 安徽农业大学学报2008，35，2： | 2 |
| 12 | Development of hepatorenal syndrome in bile duct ligated rats显示文摘AIM: To evaluate in bile duct ligated rats whether there were progressive alterations of renal function without changes in histopathology. METHODS: Male Wistar rats were submitted to sham-surgery or bile duct ligation (BDL) and divided according to the post-procedure time (2, 4 and 6-wk). To determine renal function parameters, rats wereplaced in metabolic cages and, at the end of the experiment, blood and urine samples were obtained. Histology and hydroxyproline content were analyzed in liver and renal tissue. RESULTS: Rats with 2 wk of BDL increased free water clearance (P = 0.02), reduced urinary osmolality (P = 0.03) and serum creatinine (P = 0.01) in comparison to the sham group. In contrast, rats at 6 wk of BDL showed features of HRS, including signif icant increase in serum creatinine and reductions in creatinine clearance, water excretion and urinary sodium concentration. Rats with 4 wk of BDL exhibited an intermediate stage of renal dysfunction. Progressive hepatic f ibrosis according to post-procedure time was confirmed by histology. The increased levels of liver hydroxyproline contrasted with the absence of structural changes in the kidney, as assessed by histology and unchanged hydroxyproline content in renal tissue. CONCLUSION: Our data show that BDL produced progressive renal dysfunction without structural changes in the kidney, characterizing HRS. The present model will be useful to understand the pathophysiology of HRS. | Regina M Pereira Robson AS dos Santos Eduardo A Oliveira Virgínia HR Leite Filipi LC Dias Alysson S Rezende Lincoln P Costa Lucíola S Barcelos Mauro M Teixeira Ana Cristina Sim■es e Silva | 2008 | World Journal of Gastroenterology2008，14，28： | 2 |

| 14 | Seismic performance and comparison of three different I beam to box column joints显示文摘Despite the inherently advantages of the box column, finding the best option for the I beam to the box column connection is the main challenge in using the box column as a structural member for special moment frames. In this paper, the seismic performance of unreinforced connection, weakened connection and strengthened connection was evaluated through a comprehensive experimental program. The seismic comparisons were fabricated by assessing the strength, ductility and energy dissipation in each configuration. Three full scale tests with several connections were carried out. All the specimens were subjected to cyclic loading and prior to failure by forming a plastic hinge in the beam, all the connections managed to reach an inelastic rotation of more than 6.0% rad. The experimental and analytical results showed that the seismic performance of the strengthened connection with flange and shear plates turned out to be the most effective in the beam to the box column connection. Moreover, the normalized stress distribution of the continuity plates revealed that the possibility of the weld fracture in unreinforced connection is more than other specimens. | Z.Saneei Nia A.Mazroi M.Ghassemieh H.Pezeshki | 2014 | Earthquake Engineering and Engineering Vibration2014，13，4： | 2 |
| 15 | Transparent conductive oxide-gated silicon microring with extreme resonance wavelength tunability显示文摘Transparent conductive oxides have attracted escalating research interest for integrated photonic devices and metasurfaces due to the extremely large electro-optic modulation of the refractive index by the free-carrier-induced plasma dispersion effect. In this paper, we have designed and fabricated a silicon microring resonator using an indium-tin oxide gate as the electric-tuning electrode. It achieved an ultralarge resonance wavelength tunability of 271 pm/V, which is obtained through the reduced width of the ring waveguide and a high-dielectric-constant Hf O2 insulator. We demonstrated a broad resonance wavelength tuning range of over 2 nm with an ultrafast response time of less than 12 ns and near-zero static power consumption, which outperforms traditional thermal tuning. | ERWEN LI BEHZAD ASHRAFI NIA BOKUN ZHOU ALAN X.WANG | 2019 | Photonics Research2019，7，4： | 2 |
