| 1 | Percutaneous radiofrequency ablation for early hepatocellular carcinoma: Risk factors for survival显示文摘AIM: To evaluate outcomes of radiofrequency ablation(RFA) therapy for early hepatocellular carcinoma(HCC) and identify survival- and recurrence-related factors. METHODS: Consecutive patients diagnosed with early HCC by computed tomography(CT) or magnetic resonance imaging(MRI)(single nodule of ≤ 5 cm, or multi-(up to 3) nodules of ≤ 3 cm each) and who underwent RFA treatment with curative intent between January 2010 and August 2011 at the Instituto do Cancer do Estado de S o Paulo, Brazil were enrolled in the study. RFA of the liver tumors(with 1.0 cm ablative margin) was carried out under CT-fluoro scan and ultrasonic image guidance of the percutaneous ablation probes. Procedure-related complications were recorded. At 1-mo post-RFA and 3-mo intervals thereafter, CT and MRI were performed to assess outcomes of complete response(absence of enhancing tissue at the tumor site) or incomplete response(enhancing tissue remaining at the tumor site). Overall survival and diseasefree survival rates were estimated by the Kaplan-Meier method and compared by the log rank test or simple Cox regression. The effect of risk factors on survival was assessed by the Cox proportional hazard model. RESULTS: A total of 38 RFA sessions were performed during the study period on 34 patients(age in years: mean, 63 and range, 49-84). The mean follow-up time was 22 mo(range, 1-33). The study population showed predominance of male sex(76%), less severe liver disease(Child-Pugh A, n = 26; Child-Pugh B, n = 8), and single tumor(65%). The maximum tumor diameters ranged from 10 to 50 mm(median, 26 mm). The initial(immediately post-procedure) rate of RFAinduced complete tumor necrosis was 90%. The probability of achieving complete response was significantly greater in patients with a single nodule(vs patients with multi-nodules, P = 0.04). Two patients experienced major complications, including acute pulmonary edema(resolved with intervention) and intestinal perforation(led to death). The 1- and 2-year overall survival rates were 82% and 71%, respectively. Sex, tumor size, initial response, and recurrence status influenced survival, but did not reach the threshold of statistical significance. Child-Pugh class and the model for end-stage liver disease score were identified as predictors of survival by simple Cox regression, but only Child-Pugh class showed a statistically significant association to survival in multiple Cox regression analysis(HR = 15; 95%CI: 3-76 mo; P = 0.001). The 1-and 2-year cumulative disease-free survival rates were 65% and 36%, respectively. CONCLUSION: RFA is an effective therapy for local tumor control of early HCC, and patients with preserved liver function are the best candidates. | Luciana Kikuchi Marcos Menezes Aline L Chagas Claudia M Tani Regiane SSM Alencar Marcio A Diniz Venncio AF Alves Luiz Augusto Carneiro D’Albuquerque Flair José Carrilho | 2014 | World Journal of Gastroenterology2014，20，6： | 5 |
| 2 | Complex interactomes and post-translational modifications of the regulatory proteins HABP4 and SERBP1 suggest pleiotropic cellular functions显示文摘The 57 kDa antigen recognized by the Ki-1 antibody,is also known as intracellular hyaluronic acid binding protein 4 and shares 40.7%identity and 67.4%similarity with serpin mRNA binding protein 1,which is also named CGI-55,or plasminogen activator inhibitor type-1-RNA binding protein-1,indicating that they might be paralog proteins,possibly with similar or redundant functions in human cells.Through the identification of their protein interactomes,both regulatory proteins have been functionally implicated in transcriptional regulation,mRNA metabolism,specifically RNA splicing,the regulation of mRNA stability,especially,in the context of the progesterone hormone response,and the DNA damage response.Both proteins also show a complex pattern of post-translational modifications,involving Ser/Thr phosphorylation,mainly through protein kinase C,arginine methylation and SUMOylation,suggesting that their functions and locations are highly regulated.Furthermore,they show a highly dynamic cellular localization pattern with localizations in both the cytoplasm and nucleus as well as punctuated localizations in both granular cytoplasmic protein bodies,upon stress,and nuclear splicing speckles.Several reports in the literature show altered expressions of both regulatory proteins in a series of cancers as well as mutations in their genes that may contribute to tumorigenesis.This review highlights important aspects of the structure,interactome,post-translational modifications,sub-cellular localization and function of both regulatory proteins and further discusses their possible functions and their potential as tumor markers in different cancer settings. | Carolina Colleti Talita Diniz Melo-Hanchuk Flavia Regina Moraes da Silva Angela Saito Jorg Kobarg | 2019 | World Journal of Biological Chemistry2019，10，3： | 4 |
| 3 | Perspectives on new biomarkers in gastric cancer: Diagnostic and prognostic applications显示文摘Gastric cancer is considered one of the most deadly tumors worldwide. Even with the decline in its incidence, the mortality rate of this disease has remained high, mainly due to its late diagnosis and to the lack of precise prognostic markers. The main purpose of this review is to present genetic, epigenetic and proteomic molecular markers that may be used in a diagnostic and prognostic manner and to discuss the pros and cons of each type of marker for improving clinical practice. In this sense, we observed that the use of genetic markers, especially mutations and polymorphisms, should be carefully considered, as they are strongly affected by ethnicity. Proteomic-based markers show promise, but the higher costs of the associated techniques con-tinue to make this approach expensive for routine use. Alternatively, epigenetic markers appear to be very promising, as they can be detected in bodily fluids as well as tissues. However, such markers must be used carefully because epigenetic changes may occur due to environmental factors and aging. Despite the advances in technology and its access, to date, there are few defined biomarkers of prognostic and diagnostic use for gastric tumors. Therefore, the use of a panel of several approaches(genetic, epigenetic and proteomic) should be considered the best alternative for clinical practice. | Danilo do Rosário Pinheiro Wallax Augusto Silva Ferreira Mariceli Baia Leo Barros Mariana Diniz Araújo Symara Rodrigues-Antunes Bárbara do Nascimento Borges | 2014 | World Journal of Gastroenterology2014，20，33： | 4 |
| 4 | Antifungal activity and antidiarrheal activity via antimotility mechanisms of (-)-fenchone in experimental models显示文摘BACKGROUND(-)-Fenchone is a bicyclic monoterpene present in essential oils of plant species,such as Foeniculum vulgare and Peumus boldus,used to treatment of gastrointestinal diseases.Pharmacological studies report its anti-inflammatory,antioxidant,and antinociceptive activity.AIM To investigate antidiarrheal activity related to gastrointestinal motility,intestinal secretion and antimicrobial activity.METHODS A castor oil-induced diarrhea model was used to evaluate antidiarrheal activity.Intestinal transit and gastric emptying protocols were used to assess a possible antimotility effect.Muscarinic receptors,presynaptic α2-adrenergic and tissue adrenergic receptors,KATP channels,nitric oxide were investigated to uncover antimotility mechanisms of action and castor oil-induced enteropooling to elucidate antisecretory mechanisms.The antimicrobial activity was evaluated in the minimum inhibitory concentration model,the fractional inhibitory concentration index using the(-)-fenchone association method with standard antifungal agents.RESULTS(-)-Fenchone(75,150 and 300 mg/kg)showed antidiarrheal activity,with a significant decrease in the evacuation index.This activity is possibly related to a percentage of reduced intestinal transit(75,150 and 300 mg/kg).The antimotility effect of(-)-fenchone decreased in the presence of pilocarpine,yohimbine,propranolol,L-NG-nitroarginine methyl ester or glibenclamide.In the enteropooling model,no reduction in intestinal fluid weight was observed.(-)-Fenchone did not show antibacterial activity;on the other hand,inhibits the growth of strains of fungi with a minimum fungicide concentration of 32μg/mL.However,when it was associated with amphotericin B,no synergism was observed.CONCLUSION The antidiarrheal effect of(-)-fenchone in this study involves antimotility effect and not involve antisecretory mechanisms.(-)-Fenchone presents antifungal activity;however,it did not show antibacterial activity. | Michelle Liz de Souza Pessoa Leiliane Macena Oliveira Silva Maria Elaine Cristina Araruna Catarina Alves de Lima Serafim Edvaldo Balbino Alves Junior Alessa Oliveira Silva Matheus Marley Bezerra Pessoa Hermes Diniz Neto Edeltrudes de Oliveira Lima Leonia Maria Batista | 2020 | World Journal of Gastroenterology2020，26，43： | 2 |
| 5 | “Stop Ne(c)king around”: How interactomics contributes to functionally characterize Nek family kinases显示文摘Aside from Polo and Aurora, a third but less studied kinase family involved in mitosis regulation is the never in mitosis-gene A(NIMA)-related kinases(Neks). The founding member of this family is the sole member NIMA of Aspergillus nidulans, which is crucial for the initiation of mitosis in that organism. All 11 human Neks have been functionally assigned to one of the three core functions established for this family in mammals:(1) centrioles/mitosis;(2) primary ciliary function/ciliopathies; and(3) DNA damage response(DDR). Recent findings, especially on Nek 1 and 8, showed however, that several Neks participate in parallel in at least two of these contexts: primary ciliary function and DDR. In the core section of this in-depth review, we report the current detailed functional knowledge on each of the 11 Neks. In the discussion, we return to the cross-connections among Neks and point out how our and other groups' functional and interactomics studies revealed that most Neks interact with protein partners associated with two if not all three of the functional contexts. We then raise the hypothesis that Neks may be the connecting regulatory elements that allow the cell to fine tune and synchronize the cellular events associated with these three core functions. The new and exciting findings on the Nek family open new perspectives and should allow the Neks to finally claim the attention they deserve in the field of kinases and cell cycle biology. | Gabriela Vaz Meirelles Arina Marina Perez Edmárcia Elisa de Souza Ferna Luisa Basei Priscila Ferreira Papa Talita Diniz Melo Hanchuk Vanessa Bomfim Cardoso Jrg Kobarg | 2014 | World Journal of Biological Chemistry2014，5，2： | 2 |

| 7 | Interleukin-6-174G/C polymorphism is associated with a decreased risk of type 2 diabetes in patients with chronic hepatitis C virus显示文摘BACKGROUND Chronic hepatitis C(CHC)is associated with type 2 diabetes mellitus.Although the pathogenesis remains to be elucidated,a growing evidence has suggested a role of pro-inflammatory immune response.Increased serum concentrations of Interleukin 6(IL-6)have been associated with insulin resistance,type 2 diabetes mellitus as well as advanced forms of liver disease in chronic hepatitis C infection.AIM To investigate the frequency of IL-6-174G/C(rs1800795)single nucleotide polymorphism(SNP)in CHC patients and in healthy subjects of the same ethnicity.Associations between type 2 diabetes mellitus(dependent variable)and demographic,clinical,nutritional,virological and,IL-6 genotyping data were also investigated in CHC patients.METHODS Two hundred and forty-five patients with CHC and 179 healthy control subjects(blood donors)were prospectively included.Type 2 diabetes mellitus was diagnosed according to the criteria of the American Diabetes Association.Clinical,biochemical,histological and radiological methods were used for the diagnosis of the liver disease.IL-6 polymorphism was evaluated by Taqman SNP genotyping assay.The data were analysed by logistic regression models.RESULTS Type 2 diabetes mellitus,blood hypertension and liver cirrhosis were observed in 20.8%(51/245),40.0%(98/245)and 38.4%(94/245)of the patients,respectively.The frequency of the studied IL-6 SNP did not differ between the CHC patients and controls(P=0.81)and all alleles were in Hardy-Weinberg equilibrium(P=0.38).In the multivariate analysis,type 2 diabetes mellitus was inversely associated with GC and CC genotypes of IL-6-174(OR=0.42;95%CI=0.22-0.78;P=0.006)and positively associated with blood hypertension(OR=5.56;95%CI=2.79-11.09;P<0.001).CONCLUSION This study was the first to show that GC and CC genotypes of IL-6-174 SNP are associated with a decreased risk of type 2 diabetes mellitus in patients chronically infected with hepatitis C virus.The identification of potential inflammatory mediators involved in the crosstalk between hepatitis C virus and the axis pancreas-liver remains important issues that deserve further investigations. | Cliviany Borges da Silva Diego Alves Vieira Luisa Freitas de Melo Anna Luiza Soares Chagas Adriana Dias Gomes César Lúcio Lopes de Faria Jr Rosangela Teixeira Dulciene Maria de Magalh?es Queiroz Gifone Aguiar Rocha Maria Marta Sarquis Soares Juliana Maria Trindade Bezerra Luciana Diniz Silva | 2020 | World Journal of Hepatology2020，12，4： | 2 |
| 8 | Chemical and microbiological characterization of tinctures and microcapsules loaded with Brazilian red propolis extract显示文摘The aim of this study was to characterize tinctures and microcapsules loaded with an ethanol extract of red propolis through chemical, physicochemical and microbiological assays in order to establish quality control tools for nutraceutical preparations of red propolis. The markers(isoflavonoids, chalcones, pterocarpans,flavones, phenolic acids, terpenes and guttiferones) present in the tinctures A and B were identified and confirmed using LC/ESI/FTMS/Orbitrap. Four compositions(A, B, C and D) were prepared to contain B tincture of the red propolis with some pharmaceutical excipients and submitted to two drying processes, i. e.spray-drying and freeze-drying to obtain microcapsules loaded with the red propolis extract. The tinctures and microcapsules of the red propolis were submitted to the total flavonoid content and antioxidant activity tests.The antibacterial activity and minimum inhibitory concentration(MIC) were tested using Staphylococcus aureus ATCC 25293 and Pseudomonas aeruginosa ATCC 27853 strains. The tinctures and microcapsules presented high flavonoid quantities from 20.50 to 40.79 mg/100 mg of the microcapsules. The antioxidant activity and IC50 were determined for the tinctures A and B(IC50: 6.95 μg/m L and 7.48 μg/m L), the spray-dried microcapsules(IC50: 8.89–15.63 μg/m L) and the freeze-dried microcapsules(IC50: 11.83–23.36 μg/m L). The tinctures and microcapsules were proved to be bioactive against gram-positive and gram-negative bacteria with inhibition halos superior to 10 mm at concentration of 200 μg/m L and MIC values of 135.87–271.74 μg/m L using gram-positive strain and 271.74–543.48 μg/m L using gram-negative strain. The tinctures and microcapsules of the red propolis have a potential application for nutraceutical products. | Erika Tayse da Cruz Almeida Maria Cristina Delgado da Silva José Marcos dos Santos Oliveira Regianne Umeko Kamiya Rodolfo Elleson dos Santos Arruda Danilo Abreu Vieira Valdemir da Costa Silva Pierre Barnabé Escodro Irinaldo Diniz Basílio-Júnior Ticiano Gomes do Nascimento | 2017 | Journal of Pharmaceutical Analysis2017，7，5： | 2 |
