| 3 | Prostate cancer: the need for biomarkers and new therapeutic targets显示文摘研究目的:这篇综述系统地阐述了前列腺癌的发生、发展、相关分子信号通路以及分子标志物用于前列腺癌的临床诊断和前列腺癌诊治所面临的挑战。重要结论:许多分子信号通路通过影响细胞生长、凋亡、血管生成等病理生理过程而参与了前列腺癌的起始、发生和发展。这些研究基础有助于寻找前列腺癌的肿瘤标志物和改进前列腺癌的治疗。虽然去势治疗是早期前列腺癌治疗的金标准,但是晚期的激素抵抗型前列腺癌(CRPC)的治疗仍面临着巨大的挑战。所幸的是,目前研究发现可以通过切断特异的蛋白-蛋白相互作用或者通过调节某些影响肿瘤生长和转移的关键分子来治疗前列腺癌,能减少传统治疗所带来的副作用;相关临床研究已开始实施。这些研究进展给前列腺癌的诊治带来了新的曙光。 | Juliana FELGUEIRAS Joana Vieira SILVA Margarida FARDILHA | 2014 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2014，15，1： | 11 |
| 4 | Autoimmune hepatitis and anti-tumor necrosis factor alpha therapy:A single center report of 8 cases显示文摘This article describes cases of anti-tumor necrosis factor(TNF)-α-induced autoimmune hepatitis and evaluates the outcome of these patients in relation to their immunosuppressive strategy. A retrospective analysis of medical records was performed in our center, in order to detect cases of autoimmune hepatitis(AIH) associated with anti-TNF biologic agents. We describe and analyze eight cases of AIH following anti-TNF therapy, 7 with infliximab and 1 with adalimumab. A distinction should be made between induction of autoimmunity and clinically evident autoimmune disease. Liver biopsy is useful in detecting the role of the TNF-α antagonist in the development of AIH. The lack of relapse after discontinuing immunosuppressive therapy favors, as in this case series, an immune-mediated drug reaction as most patients with AIH have a relapse after treatment is suspended. Although AIH related to anti-TNF therapy is rare, a baseline immunological panel along with liver function tests should be performed in all patients with autoimmune disease before starting biologics. | Susana Rodrigues Susana Lopes Fernando Magro Hélder Cardoso Ana Maria Horta e Vale Margarida Marques Eva Mariz Miguel Bernardes Joanne Lopes Fátima Carneiro Guilherme Macedo | 2015 | World Journal of Gastroenterology2015，21，24： | 9 |
| 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 | The role of mouse models in colorectal cancer research—The need and the importance of the orthotopic models显示文摘Colorectal cancer is a worldwide health burden,with high incidence and mortality,especially in the advanced stages of the disease.Preclinical models are very important and valuable to discover and validate early and specific biomarkers as well as new therapeutic targets.In order to accomplish that,the animal models must replicate the clinical evolution of the disease in all of its phases.In this article,we review the existent mouse models,with their strengths and weaknesses in the replication of human cancer disease progression,with major focus on orthotopic models. | Rui C.Oliveira Ana Margarida Abrantes JoseGuilherme Tralhao Maria Filomena Botelho | 2020 | Animal Models and Experimental Medicine2020，3，1： | 5 |
| 7 | Understanding 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 | 2018 | Journal of Plant Ecology2018，11，1： | 4 |
| 8 | Imbalance in T-cell differentiation as a biomarker of chronic diabetic foot ulceration显示文摘Diabetes is a growing epidemic due to the systematic increase in overweight and obesity,and chronic diabetic foot ulcers(DFUs)are the most debilitating and costly complication of diabetes.Prevention is still essential for DFU care,but early detection is limited because we do not have a good DFU biomarker.Here,we report the preliminary results of a large longitudinal study to test the effectiveness of the use of T-cell phenotype and TCR repertoire diversity as DFU biomarkers.Our results show that the ratio of effector/naïve T-cells and the number of TCR expansions are valuable biomarkers of DFU prognosis. | Joao Moura Joao Rodrigues Marta Gonçalves Claudia Amaral Margarida Lima Eugenia Carvalho | 2019 | Cellular & Molecular Immunology2019，16，10： | 4 |
| 9 | Interference of iron as a coagulant on MIB removal by powdered activated carbon adsorption for low turbidity waters显示文摘Powered activated carbon (PAC) is widely used in water treatment plants to minimize odors in drinking water. This study investigated the removal of 2-methylisoborneol (MIB) by PAC adsorption, combined with coagulation using iron as a coagulant. The adsorption and coagulation process were studied through different case scenarios of jar tests. The analysis evaluated the effect of PAC dosing in the liquid phase immediately before or after the coagulant addition. Ferric sulphate was used as the coagulant with dosages from 10 to 30 mg/L, and PAC dosages varied from 10 to 40 mg/L. The highest MIB removal efficiency (about 70%) was achieved without the coagulant addition and with the highest PAC dosage (40 mg/L). Lower MIB removal efficiencies were observed in the presence of coagulant, showing a clear interference of the iron precipitate or coagulant in the adsorption process. The degree of interference of the coagulation process in the MIB removal was proportional to the ratio of ferric hydroxide mass to the PAC mass. For both cases of PAC dosing, upstream and downstream of the coagulant injection point, the MIB removal efficiency was similar. However, MIB removal efficiency was 15% lower when compared with experiments without the coagulant application. This interference in the MIB adsorption occurs potentially because the coagulant coats the surface of the carbon and interferes with the MIB coming in contact with the carbon's surface and pores. This constraint requires an increase of the PAC dosage to provide the same efficiency observed without coagulation. | Ferreira Filho SIDNEY SECKLER Marchetto MARGARIDA Alves Laganaro ROSEMEIRE | 2013 | Journal of Environmental Sciences2013，25，8： | 3 |
| 10 | Early-onset colorectal cancer:A review of current knowledge显示文摘Colorectal cancer(CRC)is one of the most prevalent malignancies worldwide.Although most prevalent among older people,its incidence above 50 years old has been decreasing globally in the last decades,probably as a result of better screening.Paradoxically,its incidence in patients below 50 years old[early-onset CRC(EO-CRC)]has been increasing,for reasons not yet fully understood.EOCRC’s increasing incidence is genre independent but shows racial disparities and has been described to occur worldwide.It follows a birth-cohort effect which probably reflects a change in exposure to CRC risk factors.Its incidence is predicted to double until 2030,which makes EO-CRC a serious public health issue.Both modifiable and non-modifiable risk factors have been identified-some are potential targets for preventive measures.EO-CRC is often diagnosed at advanced stages and histological features associated with poor prognosis have been described.EO-CRC presents some distinctive features:Microsatellite instability is common,but another subtype of tumours,both microsatellite and chromosome stable also seems relevant.There are no age-specific treatment protocols and studies on EO-CRC survival rates have shown conflicting data.Due to the higher germline pathological mutations found in EO-CRC patients,an accurate genetic risk evaluation should be performed.In this review,we summarize the current evidence on epidemiological,clinical,histopathological and molecular features of EO-CRC and discuss the contribution of genetics and lifestyle risk factors.We further comment on screening strategies and specific dimensions to consider when dealing with a younger cancer patient. | Margarida R Saraiva Isadora Rosa Isabel Claro | 2023 | World Journal of Gastroenterology2023，29，8： | 3 |
| 11 | Urgent tracheostomy: four-year experience in a tertiary hospital显示文摘BACKGROUND: Urgent airway management is one of the most important responsibilities of otolaryngologists, often requiring a multidisciplinary approach. Urgent surgical airway intervention is indicated when an acute airway obstruction occurs or there are intubation difficulties. In these situations, surgical tracheostomy becomes extremely important.METHODS: We retrospectively studied the patients who underwent surgical tracheostomy from 2011 to 2014 by an otolaryngologist team at the operating theater of the emergency department of a tertiary hospital. Indications, complications and clinical evolution of the patients were reviewed.RESULTS: The study included 56 patients(44 men and 12 women) with a median age of 55 years. The procedure was performed under local anesthesia in 21.4% of the patients. Two(3.6%) patients were subjected to conversion from cricothyrostomy to tracheostomy. Head and neck neoplasm was indicated in 44.6% of the patients, deep neck infection in 19.6%, and bilateral vocal fold paralysis in 10.7%. Stridor was the most frequent signal(51.8%). Of the 56 patients, 15 were transferred to another hospital. Among the other 41 patients, 21 were decannulated(average time: 4 months), and none of them were cancer patients. Complications occurred in 5(12.2%) patients: hemorrhage in 3, surgical wound infection in 1, and cervico-thoracic subcutaneous emphysema in 1. No death was related to the procedure.CONCLUSION: Urgent tracheostomy is a life-saving procedure for patients with acute airway obstruction or with diffi cult intubation. It is a safe and effective procedure, with a low complication rate, and should be performed before the patient's clinical status turns into a surgical emergency situation. | Liliana Costa Ricardo Matos Sara Julio Fernando Vales Margarida Santos | 2016 | World Journal of Emergency Medicine2016，7，3： | 3 |
| 12 | 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 |

| 14 | Biomarkers of hypoxic-ischemic encephalopathy:a systematic review显示文摘Background Current diagnostic criteria for hypoxic–ischemic encephalopathy in the early hours lack objective measurement tools.Therefore,this systematic review aims to identify putative molecules that can be used in diagnosis in daily clinical practice(PROSPERO ID:CRD42021272610).Data sources Searches were performed in PubMed,Web of Science,and Science Direct databases until November 2020.English original papers analyzing samples from newborns>36 weeks that met at least two American College of Obstetricians and Gynecologists diagnostic criteria and/or imaging evidence of cerebral damage were included.Bias was assessed by the Newcastle–Ottawa Scale.The search and data extraction were verified by two authors separately.Results From 373 papers,30 met the inclusion criteria.Data from samples collected in the first 72 hours were extracted,and increased serum levels of neuron-specific enolase and S100-calcium-binding protein-B were associated with a worse prognosis in newborns that suffered an episode of perinatal asphyxia.In addition,the levels of glial fibrillary acidic protein,ubiquitin carboxyl terminal hydrolase isozyme-L1,glutamic pyruvic transaminase-2,lactate,and glucose were elevated in newborns diagnosed with hypoxic–ischemic encephalopathy.Moreover,pathway analysis revealed insulin-like growth factor signaling and alanine,aspartate and glutamate metabolism to be involved in the early molecular response to insult.Conclusions Neuron-specific enolase and S100-calcium-binding protein-B are potential biomarkers,since they are correlated with an unfavorable outcome of hypoxic-ischemic encephalopathy newborns.However,more studies are required to determine the sensitivity and specificity of this approach to be validated for clinical practice. | Ines Caramelo Margarida Coelho Miguel Rosado Carla M.P.Cardoso Alexandra Dinis Carlos B.Duarte Mario Graos Bruno Manadas | 2023 | World Journal of Pediatrics2023，19，6： | 2 |

| 16 | Anemia in patients with high-risk acute coronary syndromes admitted to Intensive Cardiac Care Units显示文摘Background Little information exists about the role of anemia in patients with acute coronary syndromes(ACS)admitted to Intensive Cardiac Care Units(ICCU).The aim of this study was to assess the prevalence of anemia and its impact on management and outcomes in this clinical setting.Methods All consecutive patients admitted to eight different ICCUs with diagnosis of non-ST segment elevation ACS(NSTEACS)were prospectively included.Anemia was defined as hemoglobin<130 g/L in men and<120 g/L in women.The association between anemia and mortality or readmission at six months was assessed by the Cox regression method.Results A total of 629 patients were included.Mean age was 66.6 years.A total of 197 patients(31.3%)had anemia.Coronary angiography was performed in most patients(96.2%).Patients with anemia were significantly older,with a higher prevalence of comorbidities,poorer left ventricle ejection fraction and higher GRACE score values.Patients with anemia underwent less often coronary angiography,but underwent more often intraaortic counterpulsation,non-invasive mechanical ventilation and renal replacement therapies.Both ICCU and hospital stay were significantly longer in patients with anemia.Both the incidence of mortality(HR=3.36,95%CI:1.43–7.85,P=0.001)and the incidence of mortality/readmission were significantly higher in patients with anemia(HR=2.80,95%CI:2.03–3.86,P=0.001).After adjusting for confounders,the association between anemia and mortality/readmission remained significant(P=0.031).Conclusions Almost one of three NSTEACS patients admitted to ICCU had anemia.Most patients underwent coronary angiography.Anemia was independently associated to poorer outcomes at 6 months. | Victoria Lorente Jaime Aboal Cosme Garcia Jordi Sans-Rosello Antonia Sambola Rut Andrea Carlos Tomas Gil Bonet David Vinas Nabil el Ouaddi Santiago Montero Javier Cantalapiedra Margarida Pujol Isabel Hernandez Maria Perez-Rodriguez Isaac Llao Jose C Sanchez-Salado Miquel Gual Albert Ariza-Sole 无 | 2020 | Journal of Geriatric Cardiology2020，17，1： | 2 |
