| 1 | Cytomegalovirus frequency in neonatal intrahepatic cholestasis determined by serology, histology, immunohistochemistry and PCR显示文摘AIM: To determine cytomegalovirus (CMV) frequency in neonatal intrahepatic cholestasis by serology, histological revision (searching for cytomegalic cells), immunohistochemistry, and polymerase chain reaction (PCR), and to verify the relationships among these methods.METHODS: The study comprised 101 non-consecutive infants submitted for hepatic biopsy between March 1982 and December 2005. Serological results were obtained from the patient's f iles and the other methods were performed on paraffin-embedded liver samples from hepatic biopsies. The following statistical measures were calculated: frequency, sensibility, specif ic positive predictive value, negative predictive value, and accuracy.RESULTS: The frequencies of positive results were as follows: serology, 7/64 (11%); histological revision, 0/84; immunohistochemistry, 1/44 (2%), and PCR, 6/77 (8%). Only one patient had positive immunohistochemical fi ndings and a positive PCR. The following statistical measures were calculated between PCR and serology: sensitivity, 33.3%; specificity, 88.89%; positive predictive value, 28.57%; negative predictive value, 90.91%; and accuracy, 82.35%. CONCLUSION: The frequency of positive CMV varied among the tests. Serology presented the highest positive frequency. When compared to PCR, the sensitivity and positive predictive value of serology were low. | Maria Angela Bellomo-Brandao Paula D Andrade Sandra CB Costa Cecilia AF Escanhoela Jose Vassallo Gilda Porta Adriana MA De Tommaso Gabriel Hessel | 2009 | World Journal of Gastroenterology2009,15,27: | 8 |
| 2 | Staging of portal hypertension and portosystemic shunts using dynamic nuclear medicine investigations显示文摘AIM: To explore portal hypertension and portosys-temic shunts and to stage chronic liver disease (CLD) based on the pathophysiology of portal hemodynam-ics. METHODS: Per-rectal portal scintigraphy (PRPS) was performed on 312 patients with CLD and liver angio-scintigraphy (LAS) on 231 of them. The control group included 25 healthy subjects. We developed a new model of PRPS interpretation by introducing two new parameters,the liver transit time (LTT) and the circu-lation time between right heart and liver (RHLT). LTT for each lobe was used to evaluate the early portal hypertension. RHLT is useful in cirrhosis to detect liver areas missing portal in? ow. We calculated the classical per-rectal portal shunt index (PRSI) at PRPS and the hepatic perfusion index (HPI) at LAS. RESULTS: The normal LTT value was 24 ± 1 s. Abnor-mal LTT had PPV = 100% for CLD. Twenty-seven non-cirrhotic patients had LTT increased up to 35 s (median 27 s). RHLT (42 ± 1 s) was not related to liver disease. Cirrhosis could be excluded in all patients with PRSI < 5% (P < 0.01). PRSI > 30% had PPV = 100% for cirrhosis. Based on PRPS and LAS we propose the clas-sifi cation of CLD in 5 hemodynamic stages. Stage 0 is normal (LTT = 24 s,PRSI < 5%). In stage 1,LTT is increased,while PRSI remains normal. In stage 2,LTT is decreased between 16 s and 23 s,whereas PRSI is increased between 5% and 10%. In stage 3,PRSI is increased to 10%-30%,and LTT becomes undetect-able by PRPS due to the portosystemic shunts. Stage 4 includes the patients with PRSI > 30%. RHLT and HPI were used to subtype stage 4. In our study stage 0 had NPV = 100% for CLD,stage 1 had PPV = 100% for non-cirrhotic CLD,stages 2 and 3 represented the transition from chronic hepatitis to cirrhosis,stage 4 had PPV = 100% for cirrhosis. CONCLUSION: LTT allows the detection of early por-tal hypertension and of opening of transhepatic shunts. PRSI is useful in CLD with extrahepatic portosystemic shunts. Our hemodynamic model stages the evolution of portal hypertension and portosystemic shunts. It may be of use in the selection of patients for interferon therapy. | Mircea Dragoteanu Ioan A Balea Liliana A Dina Cecilia D Piglesan Ioana Grigorescu Stefan Tamas Sabin O Cotul | 2008 | World Journal of Gastroenterology2008,14,24: | 7 |
| 3 | Management of oligometastatic non-small cell lung cancer patients:Current controversies and future directions显示文摘Oligometastatic non-small cell lung cancer(NSCLC)describes an intermediate stage of NSCLC between localized and widely-disseminated disease.This stage of NSCLC is characterized by a limited number of metastases and a more indolent tumor biology.Currently,the management of oligometastatic NSCLC involves radical treatment(radiotherapy or surgery)that targets the metastatic lesions and the primary tumor to achieve disease control.This approach offers the potential to achieve prolonged survival in patients who,in the past,would have only received palliative measures.The optimal therapeutic strategies for the different scenarios of oligometastatic disease(intracranial vs extracranial disease,synchronous vs metachronous)remain undefined.Given the lack of head-to-head studies comparing radiotherapy to surgery in these patients,the decision to apply surgery or radiotherapy(with or without systemic treatment)must be based on prognostic factors that allow us to classify patients.This classification will allow us to select the most appropriate therapeutic strategy on an individualized basis.In the future,the molecular or microRNA profiles will likely improve the treatment selection process.The objective of the present article is to review the most relevant scientific evidence on the management of patients with oligometastatic NSCLC,focusing on the role of radiotherapy and surgery.We also discuss areas of controversy and future directions. | Felipe Counago Javier Luna Luis Leonardo Guerrero Blanca Vaquero María Cecilia Guillén-Sacoto Teresa González-Merino Begona Taboada Verónica Díaz Belén Rubio-Viqueira Ana Aurora Díaz-Gavela Francisco JoséMarcos Elia del Cerro | 2019 | World Journal of Clinical Oncology2019,10,10: | 5 |
| 4 | Hepatitis C virus-related B cell subtypes in non Hodgkin's lymphoma显示文摘AIM:To evaluate if indolent B cell-non Hodgkin's lymphoma(B-NHL) and diffuse large B-cell lymphoma(DLBCL) in hepatitis C virus(HCV) positive patients could have different biological and clinical characteristics requiring different management strategies.METHODS:A group of 24 HCV related B-NHL patients(11 indolent,13 DLBCL) in whom the biological and clinical characteristics were described and confronted.Patients with DLBCL were managed with the standard of care of treatment.Patients with indolent HCV-related B-NHL were managed with antiviral treatment pegylated interferon plus ribavirin and their course observed.The outcomes of the different approaches were compared.RESULTS:Patients with DLBCL had a shorter duration of HCV infection and a higher prevalence of HCV genotype 1 compared to patients with indolent B-NHL in which HCV genotype 2 was the more frequent genotype.Five of the 9 patients with indolent HCV-relatedB-NHL treated with only antiviral therapy,achieved a complete response of their onco-haematological disease(55%).Seven of the 13 DLBCL patients treated with immunochemotheraphy obtained a complete response(54%).CONCLUSION:HCV genotypes and duration of HCV infection differed between B-NHL subtypes.Indolent lymphomas can be managed with antiviral treatment,while DLBCL is not affected by the HCV infection. | Adriano M Pellicelli Massimo Marignani Valerio Zoli Mario Romano Aldo Morrone Lorenzo Nosotti Giuseppe Barbaro Antonio Picardi Umberto Vespasiani Gentilucci Daniele Remotti Cecilia D'Ambrosio Caterina Furlan Fabrizio Mecenate Ettore Mazzoni Ignazio Majolino Roberto Villani Arnaldo Andreoli Giorgio Barbarini | 2011 | World Journal of Hepatology2011,3,11: | 4 |
| 5 | 5-ASA colonic mucosal concentrations resulting from different pharmaceutical formulations in ulcerative colitis显示文摘AIM:To compare the mucosal concentrations of 5-aminosalicylic acid(5-ASA)resulting from different pharmaceutical formulations and analyse the influence of inflammation on the mucosal concentrations.METHODS:The study included 130 inflammatory bowel disease(IBD)patients receiving 5-ASA as pH-dependent-release formulations(73 patients),time-dependent-release formulations(11 patients),or pro-drugs(18patients).In addition,28 patients were receiving topical treatment(2-4 g/d)with pH-dependent-release formulations.Endoscopic biopsies were obtained from the sigmoid region during the colonoscopy.The 5-ASA concentrations(ng/mg)were measured in tissue homogenatesusing high-pressure liquid chromatography with electrochemical detection.The t test and Mann-Whitney test,when appropriate,were used for statistical analysis.RESULTS:Patients receiving pH-dependent-release formulations showed significantly higher mucosal concentrations of 5-ASA(51.75±5.72 ng/mg)compared with patients receiving pro-drugs(33.35±5.78 ng/mg,P=0.01)or time-dependent-release formulations(38.24±5.53 ng/mg,P=0.04).Patients with endoscopic remission had significantly higher mucosal concentrations of5-ASA than patients with active disease(60.14±7.95ng/mg vs 35.66±5.68 ng/mg,P=0.02).Similar results were obtained when we compared patients with the histological appearance of remission and patients with active histological inflammation(67.53±9.22 ng/mg vs 35.53±5.63 ng/mg,P<0.001).Significantly higher mucosal concentrations of 5-ASA were detected in patients treated with both oral and topical treatments in combination compared with patients who received oral treatment with pH-dependent-release formulations alone(72.33±11.23 ng/mg vs 51.75±5.72 ng/mg,P=0.03).CONCLUSION:IBD patients showed significant variability in mucosal 5-ASA concentrations depending on the type of formulation,and the highest mean concentration was achieved using pH-dependent-release formulations. | Renata D’Incà Martina Paccagnella Romilda Cardin Surajit Pathak Vincenzo Baldo Maria Cecilia Giron Giacomo Carlo Sturniolo | 2013 | World Journal of Gastroenterology2013,19,34: | 4 |
| 6 | 基于离子液的超声辅助萃取小蓼叶中的精油及真实溶剂似导体屏蔽模型研究显示文摘Ionic liquids ( ILs) based ultrasonic-assisted extract has been applied for the extraction of essential oil from Persicaria minor leaves. The effects of temperature,sonication time,and particle size of the plant material on the yield of essential oil were investigated. Among the different ILs employed,1-ethyl-3-methyli midazolium acetate was the most effective,providing a 9. 55% yield of the essential oil under optimum conditions( 70 ℃,25 min,IL ∶hexane ratio of 7 ∶10 ( v /v) ,particle size 60-80 mesh) . The performance of 1-ethyl-3-methylimidazolium acetate in the extraction was attributed to its lowviscosity and ability to disintegrate the structural matrix of the plant material. The ability of 1-ethyl-3-methylimidazolium acetate was also confirmed using the conductor like-screening model for realistic solvents. This research proves that ILs can be used to extract essential oils from lignocellulosic biomass. | Habib ULLAH Cecilia D WILFRED Maizatul S SHAHARUN | 2017 | 色谱2017,35,6: | 3 |

| 20 | Interaction network between frugivorous birds and zoochorous plants in cloud forest riparian strips immersed in anthropic landscapes显示文摘Worldwide,tropical montane cloud forest is one of the most important and biodiverse ecosystems;however,it is also one of those most threatened by anthropic activities.These activities lead to a fragmented,deforested landscape with narrow riparian forest strips immersed in an agricultural matrix dominated by pastures.Here,we characterize the interaction network between frugivorous birds and zoochorous plants in riparian strips of cloud forest in deforested landscapes of Central Veracruz,Mexico.To characterize the network of this mutualistic interaction,we estimated network-and species-level metrics using the Bipartite R package.Nestedness,modularity and robustness were used to describe network structure.Centrality measures of degree,closeness,betweenness centrality and their relative contribution to nestedness were used to determine the importance of each bird/plant species to the network’s structure.This interaction network has 24 species of birds and 30 species of plants,with low connectance(0.11),low nestedness(11.53),and intermediate but not significant modularity(0.49).The bird species most important to network stability were Chlorospingus flavopectus,Myadestes occidentalis,and Catharus mexicanus.The most important plants were Conostegia xalapensis,C.arborea,and Rubus ulmifolius.Network robustness varied from 0.36 to 0.86 and its stability is compromised when species of birds or plants with the highest values of centrality are removed,with plant removal more detrimental.Riparian strips of cloud forest crossing deforested areas maintain a relatively rich set of birds that disperse the seeds of many forest plants,thus they are crucial to the preservation of this mutualistic network in anthropic landscapes.Network stability is severely undermined by the loss of any of the few species—whether birds or plants—with high centrality values.The most important plants for this stability are pioneer tree and shrub species that provide food for several bird species,and they are also crucial to cloud forest regeneration.A worrisome finding is that some of the bird species most important to network stability are also among the most sought-after as ornamental birds by illegal collectors in the region. | Omar A.Hernández-Dávila Javier Laborde Vinicio J.Sosa Cecilia Díaz-Castelazo | 2022 | Avian Research2022,13,3: | 1 |
