| 1 | 美国国立老化研究所与阿尔茨海默病协会诊断指南写作组:阿尔茨海默病临床前阶段的定义显示文摘阿尔茨海默病(AD)的病理生理过程在痴呆诊断的多年前就开始了。这一长期的AD“临床前”阶段是治疗干预的关键机会,但需进一步阐明AD的病理级联过程和临床症状出现之间的联系。美国国立老化研究所和AD协会召集了一个国际工作组对AD生物标志物、流行病学和神经心理学的证据进行综述并提出建议,以确定能够预测由“正常”认知到轻度认知功能障碍(MCI)及AD痴呆的最佳预测指标。根据目前已有的主要科学证据,我们提出了一个概念性的框架和用于操作的研究标准,以通过纵向临床研究来验证和改进这些模型。这些建议仅用于研究目的,目前不涉及临床应用。我们希望这些建议能提供一个共识,以推进临床前AD的研究,最终推动更早期治疗干预的进展,使得一些疾病减缓药物的疗效发挥最大。 | Sperling RA Aisen PS Beckett LA Bennett DA Craft S Fagan AM Iwatsubo T Jack CR Jr Kaye J Montine TJ Park DC Reiman EM Rowe CC Siemers E Stern Y Yaffe K Carrillo MC Thies B Morrison-Bogorad M Wagster MV Phelps CH 贾建平(译) 郭起浩(译) 黄丽(译) 陆璐(译) 张逸驰(译) 邢怡(译) | 2012 | 中华神经科杂志2012,45,5: | 22 |
| 2 | Evaluation of quantitative contrast harmonic imaging to assess malignancy of liver tumors:A prospective controlled two-center study显示文摘AIM: To establish the extent to which contrast enhancement with SonoVue in combination with quantitative evaluation of contrast-medium dynamics facilitates the detection of hepatic tumors. METHODS: One hundred patients with histologically confirmed malignant or benign hepatic tumor (maximum size 5 cm) were analyzed. Contrast-enhanced ultrasound (bolus injection 2.5 mL SonoVue) was carried out with intermittent breath-holding technique using a multifrequency transducer (2.5-4 MHz). Native vascularization was analyzed with power Doppler. The contrast-enhanced dynamic ultrasound investigation was carried out with contrast harmonic imaging in true detection mode during the arterial,portal venous and late phases. Mechanical index was set at 0.15. Perfusion analysis was performed by post-processing of the raw data time intensity curve (TIC) analysis. The cut-off of the gray value differences between tumor and normal liver tissue was established using Receiver Operating Characteristic (ROC) analysis 64-line multi-slice computed tomography served as reference method in all cases. Magnetic resonance tomography was used additionally in 19 cases. RESULTS: One hundred patients with 59 malignant (43 colon,5 breast,2 endocrine metastases,7 hepatocellular carcinomas and 2 kidney cancers) and 41 benign (15 hemangiomas,7 focal nodular hyperplasias,5 complicated cysts,2 abscesses and 12 circumscribed fatty changes) tumors were included. The late venous phase proved to be the most sensitive for classification of the tumor type. Fifty-eight of the 59 malignant tumors were classified as true positive,and one as false negative. This resulted in a sensitivity of 98.3%. Of the 41 benign tumors,37 were classified as true negative and 4 as false negative,which corresponds to a specificity of 90.2%. Altogether,95.0% of the diagnoses were classified as correct on the basis of the histological classification. No investigator-dependency (P = 0.23) was noted. CONCLUSION: The results show the possibility of accurate prediction of malignancy of hepatic tumors with a positive prognostic value of 93.5% using advanced contrast-enhanced ultrasound. Contrast enhancement with SonoVue in combination with quantitative evaluation of contrast-medium dynamics is a valuable tool to discriminate hepatic tumors. | EM Jung DA Clevert AG Schreyer S Schmitt J Rennert R Kubale S Feuerbach F Jung | 2007 | World Journal of Gastroenterology2007,13,47: | 15 |
| 3 | Impact of antiretroviral therapy on lipid metabolism of human immunodeficiency virus-infected patients: Old and new drugs显示文摘For human immunodeficiency virus(HIV)-infected patients, the 1990s were marked by the introduction of highly active antiretroviral therapy(HAART) representing a new perspective of life for these patients. The use of HAART was shown to effectively suppress the replication of HIV-1 and dramatically reduce mortality and morbidity, which led to a better and longer quality of life for HIV-1-infected patients. Apart from the substantial benefits that result from the use of various HAART regimens, laboratory and clinical experience has shown that HAART can induce severe and considerable adverse effects related to metabolic complications of lipid metabolism, characterized by signs of lipodystrophy, insulin resistance, central adiposity, dyslipidemia, increased risk of cardiovascular disease and even an increased risk of atherosclerosis. New drugs are being studied, new therapeutic strategies are being implemented, and the use of statins, fibrates, and inhibitors of intestinal cholesterol absorption have been effective alternatives. Changes in diet and lifestyle have also shown satisfactory results. | Joel da Cunha Luciana Morganti Ferreira Maselli Ana Carolina Bassi Stern Celso Spada Sérgio Paulo Bydlowski | 2015 | World Journal of Virology2015,4,2: | 9 |

| 5 | Titanium dioxide induced inflammation in the small intestine显示文摘AIM:To investigate the effects of titanium dioxide (TiO2) nanoparticles (NPTiO 2 ) and microparticles (MPTiO 2 ) on the inflammatory response in the small intestine of mice. METHODS: Bl 57/6 male mice received distilled water suspensions containing TiO 2 (100 mg/kg body weight) as NPTiO 2 (66 nm), or MPTiO 2 (260 nm) by gavage for 10 d, once a day; the control group received only distilled water. At the end of the treatment the duodenum, jejunum and ileum were extracted for assessment of cytokines, inflammatory cells and titanium content. The cytokines interleukin (IL)-1b, IL-4, IL-6, IL-8, IL-10, IL-12, IL-13, IL-17, IL-23, tumor necrosis factor-α (TNF-α), intracellular interferon-γ (IFN-γ) and transforming growth factor-β (TGF-β) were evaluated by enzyme-linked immunosorbent assay in segments of jejunum and ileum (mucosa and underlying muscular tissue). CD4 + and CD8 + T cells, natural killer cells, and dendritic cells were evaluated in duodenum, jejunum and ileum samples fixed in 10% formalin by immuno-histochemistry. The titanium content was determined by inductively coupled plasma atomic emission spectrometry. RESULTS: We found increased levels of T CD4 + cells (cells/mm 2 ) in duodenum:NP 1240 ± 139.4, MP 1070 ± 154.7 vs 458 ± 50.39 (P < 0.01); jejunum:NP 908.4 ± 130.3, MP 813.8 ± 103.8 vs 526.6 ± 61.43 (P < 0.05); and ileum:NP 818.60 ± 123.0, MP 640.1 ± 32.75 vs 466.9 ± 22.4 (P < 0.05). In comparison to the control group, the groups receiving TiO 2 showed a statistically significant increase in the levels of the inflammatory cytokines IL-12, IL-4, IL-23, TNF-α, IFN-γ and TGF-β. The cytokine production was more pronounced in the ileum (mean ± SE):IL-12: NP 33.98 ± 11.76, MP 74.11 ± 25.65 vs 19.06 ± 3.92 (P < 0.05); IL-4: NP 17.36 ± 9.96, MP 22.94 ± 7.47 vs 2.19 ± 0.65 (P < 0.05); IL-23: NP 157.20 ± 75.80, MP 134.50 ± 38.31 vs 22.34 ± 5.81 (P < 0.05); TNFα: NP 3.71 ± 1.33, MP 5.44 ± 1.67 vs 0.99± 019 (P < 0.05); IFNγ: NP 15.85 ± 9.99, MP 34.08 ± 11.44 vs 2.81 ± 0.69 (P < 0.05); and TGF-β: NP 780.70 ± 318.50, MP 1409.00 ± 502.20 vs 205.50 ± 63.93 (P < 0.05). CONCLUSION:Our findings indicate that TiO2 particles induce a Th1-mediated inflammatory response in the small bowel in mice. | Carolina Maciel Nogueira Walter Mendes de Azevedo Maria Lucia Zaidan Dagli Sérgio Hiroshi Toma AndréZonetti de Arruda Leite Maria Laura Lordello Iêda Nishitokukado Carmen Lúcia Ortiz-Agostinho Maria IrmaSeixas Duarte Marcelo Alves Ferreira Aytan Miranda Sipahi | 2012 | World Journal of Gastroenterology2012,18,34: | 8 |
| 6 | Embolization of splenorenal shunt associated to portal vein thrombosis and hepatic encephalopathy显示文摘Hepatic encephalopathy(HE)is a cognitive disturbance characterized by neuropsychiatric alterations.It occurs in acute and chronic hepatic disease and also in patients with portosystemic shunts.The presence of these portosystemic shunts allows the passage of nitrogenous substances from the intestines through systemic veins without liver depuration.Therefore,the embolization of these shunts has been performed tocontrol HE manifestations,but the presence of portal vein thrombosis is considered a contraindication.In this presentation we show a cirrhotic patient with severe HE and portal vein thrombosis who was submitted to embolization of a large portosystemic shunt.Case report:a 57 years-old cirrhotic patient who had been hospitalized many times for persistent HE and hepatic coma,even without precipitant factors.She had a wide portosystemic shunt and also portal vein thrombosis.The abdominal angiography confirmed the splenorenal shunt and showed other shunts.The larger shunt was embolized through placement of microcoils,and the patient had no recurrence of overt HE.There was a little increase of esophageal and gastric varices,but no endoscopic treatment was needed.Since portosystemic shunts are frequent causes of recurrent HE in cirrhotic patients,portal vein thrombosis should be considered a relative contraindication to perform a shunt embolization.However,in particular cases with many shunts and severe HE,we found that one of these shunts can be safely embolized and this procedure can be sufficient to obtain a good HE recovery.In conclusion,we reported a case of persistent HE due to a wide portosystemic shunt associated with portal vein thrombosis.As the patient had other shunts,she was successfully treated by embolization of the larger shunt. | Letícia de Campos Franzoni Fábio Cardoso de Carvalho Rafael Gomes de Almeida Garzon Fábio da Silva Yamashiro Laís Augusti Lívia Alves Amaral Santos Mariana de Souza Dorna Júlio Pinheiro Baima Talles Bazeia Lima Carlos Antonio Caramori Giovanni Faria Silva Fernando Gomes Romeiro | 2014 | World Journal of Gastroenterology2014,20,42: | 6 |
| 7 | Activation of human fibroblast-like synoviocytes by uric acid crystals in rheumatoid arthritis显示文摘Hyperuricemia-mediated uric acid crystal formation may cause joint inflammation and provoke the destruction of joints through the activation of inflammasome-mediated innate immune responses.However,the immunopathological effects and underlying intracellular regulatory mechanisms of uric acid crystal-mediated activation of fibroblast-like synoviocytes(FLS)in rheumatoid arthritis(RA)have not been elucidated.Therefore,we investigated the in vitro effects of monosodium urate crystals,alone or in combination with the inflammatory cytokines tumor-necrosis factor(TNF)-a or interleukin(IL)-1b,on the activation of human FLS from RA patients and normal control subjects and the underlying intracellular signaling mechanisms of treatment with these crystals.Monosodium urate crystals were able to significantly increase the release of the inflammatory cytokine IL-6,the chemokine CXCL8 and the matrix metalloproteinase(MMP)-1 from both normal and RA-FLS(all P,0.05).Moreover,the additive or synergistic effect on the release of IL-6,CXCL8 and MMP-1 from both normal and RA-FLS was observed following the combined treatment with monosodium urate crystals and TNF-a or IL-1b.Further experiments showed that the release of the measured inflammatory cytokine,chemokine and MMP-1 stimulated by monosodium urate crystals were differentially regulated by the intracellular activation of extracellular signal-regulated kinase and c-Jun N-terminal kinase pathways but not the p38 mitogen-activated protein kinase pathway.Our results therefore provide a new insight into the uric acid crystal-activated immunopathological mechanisms mediated by distinct intracellular signal transduction pathways leading to joint inflammation in RA. | Da P Chen Chun K Wong Lai S Tam Edmund K Li Christopher WK Lam | 2011 | Cellular & Molecular Immunology2011,8,6: | 5 |
| 8 | MGMT and MLH1 methylation in Helicobacter pylori-infected children and adults显示文摘AIM:To evaluate the association between Helicobacter pylori(H.pylori) infection and MLH1 and MGMT methylation and its relationship with microsatellite instability(MSI).METHODS:The methylation status of the MLH1 and MGMT promoter region was analysed by methylation specific methylation-polymerase chain reaction(MSPPCR) in gastric biopsy samples from uninfected or H.pylori-infected children(n = 50),from adults with chronic gastritis(n = 97) and from adults with gastric cancer(n = 92).MLH1 and MGMT mRNA expression were measured by real-time PCR and normalised to a constitutive gene(β actin).MSI analysis was performed by screening MSI markers at 4 loci(Bat-25,Bat-26,D17S250 and D2S123) with PCR;PCR products were analysed by single strand conformation polymorphism followed by silver staining.Statistical analyses were performed with either the χ 2 test with Yates continuity correction or Fisher's exact test,and statistical significance for expression analysis was assessed using an unpaired Student's t-test.RESULTS:Methylation was not detected in the promoter regions of MLH1 and MGMT in gastric biopsy samples from children,regardless of H.pylori infection status.The MGMT promoter was methylated in 51% of chronic gastritis adult patients and was associated with H.pylori infection(P < 0.05);this region was methylated in 66% of gastric cancer patients,and the difference in the percentage of methylated samples between these patients and those from H.pylori-infected chronic gastritis patients was statistically significant(P < 0.05).MLH1 methylation frequencies among H.pylori-infected and non-infected chronic gastritis adult patients were 13% and 7%,respectively.We observed methylation of the MLH1 promoter(39%) and increased MSI levels(68%) in samples from gastric cancer patients in comparison to samples from H.pylori-infected adult chronic gastritis patients(P < 0.001 and P < 0.01,respectively).The frequency of promoter methylation for both genes was higher in gastric cancer samples than in H.pylori-positive chronic gastritis samples(P < 0.05).The levels of MLH1 and MGMT mRNA were significantly reduced in chronic gastritis samples that were also hypermethylated(P < 0.01).CONCLUSION:In summary,MGMT and MLH1 methylation did not occur in earlier-stage H.pylori infections and thus might depend on the duration of infection. | Marisa C Alvarez Juliana C Santos Nathália Maniezzo Marcelo S Ladeira Artur LC da Silva Isabel CA Scaletsky José Pedrazzoli Jr Marcelo L Ribeiro | 2013 | World Journal of Gastroenterology2013,19,20: | 5 |

| 10 | 从附睾到卵子:CRISP蛋白在哺乳动物受精过程中的作用显示文摘哺乳动物的受精过程涉及精卵结合的很多步骤,是一个非常复杂的过程,其分了机制亟待阐明。此篇综述主要论述了CRISP(富含半胱氨酸的分泌蛋白)作为模型分子在哺乳动物受精过程中的价值。大量的体外实验和基因敲出模型研究显示,附睾内的CRISP1以两种不同的亲和力结合于精子表面,参与精子获能、精子-透明带结合、精卵融合的调控。这些研究成果可以延伸至人类。我们住研究中发现,人类具有与啮齿类同源的CRISP(hCRISP1),同样参与受精过样。CRISP家族的其他成员(睾丸内CRISP2、附挈内CRISP3—4、射精时的CRISP3)也参与了精卵结合的过程,提示同源分子间的相互协同有助于受精的成功。另外,我们的研究显示,CRISP蛋白伴随精子穿越男性及女性生殖管道的全过程。我们推测CRISP不仅参与了受精过程,而且可能成为不育和避孕研究的新靶点。 | Vanina G Da Ros Mariana Weigel Munoz Maria A Battistone Nicolas G Brukman Guillermo Carvajal Ludmila Curci Matlas D Gomez-Elias Debora J Cohen Patricia S Cuasnicu | 2015 | Asian Journal of Andrology2015,17,5: | 5 |
| 11 | Transcriptome analyses of the Dof-like gene family in grapevine reveal its involvement in berry, flower and seed development显示文摘The Dof(DNA-binding with one finger)protein family spans a group of plant transcription factors involved in the regulation of several functions,such as plant responses to stress,hormones and light,phytochrome signaling and seed germination.Here we describe the Dof-like gene family in grapevine(Vitis vinifera L.),which consists of 25 genes coding for Dof.An extensive in silico characterization of the VviDofL gene family was performed.Additionally,the expression of the entire gene family was assessed in 54 grapevine tissues and organs using an integrated approach with microarray(cv Corvina)and real-time PCR(cv Pinot Noir)analyses.The phylogenetic analysis comparing grapevine sequences with those of Arabidopsis,tomato,poplar and already described Dof genes in other species allowed us to identify several duplicated genes.The diversification of grapevine DofL genes during evolution likely resulted in a broader range of biological roles.Furthermore,distinct expression patterns were identified between samples analyzed,corroborating such hypothesis.Our expression results indicate that several VviDofL genes perform their functional roles mainly during flower,berry and seed development,highlighting their importance for grapevine growth and production.The identification of similar expression profiles between both approaches strongly suggests that these genes have important regulatory roles that are evolutionally conserved between grapevine cvs Corvina and Pinot Noir. | Danielle Costenaro da Silva Vítor da Silveira Falavigna Marianna Fasoli Vanessa Buffon Diogo Denardi Porto Georgios Joannis Pappas Jr Mario Pezzotti Giancarlo Pasquali Luís Fernando Revers | 2016 | Horticulture Research2016,3,1: | 5 |

| 13 | No evidence of HPV DNA in esophageal squamous cell carcinoma in a population of Southern Brazil显示文摘AIM:To investigate the association between human papillomavirus(HPV)and esophageal squamous cell carcinoma(ESCC)in southern Brazil.METHODS:We studied 189 esophageal samples from125 patients from three different groups:(1)102 biopsies from 51 patients with ESCC,with one sample from the tumor and another from normal esophageal mucosa distant from the tumor;(2)50 esophageal biopsies from 37 patients with a previous diagnosis of head and neck squamous cell carcinoma(HNSCC);and(3)37 biopsies from esophageal mucosa with normal appearance from 37 dyspeptic patients,not exposed to smoking or alcohol consumption.Nested-polymerase chain reaction(PCR)with the MY09/11 and GP5/6 L1primers was used to detect HPV L1 in samples fixed in formalin and stored in paraffin blocks.All PCR reactions were performed with a positive control(cervicovaginal samples),with a negative control(Human Genomic DNA)and with a blank reaction containing all reagents except DNA.We took extreme care to prevent DNA contamination in sample collection,processing,and testing.RESULTS:The histological biopsies confirmed the diagnosis of ESCC in 52 samples(51 from ESCC group and 1 from the HNSCC group)and classified as well differentiated(12/52,23.1%),moderately differentiated(27/52,51.9%)or poorly differentiated(7/52,13.5%).One hundred twenty-eight esophageal biopsies were considered normal(51 from the ESCC group,42 from the HNSCC group and 35 from dyspeptic patients).Nine had esophagitis(7 from the HNSCC and 2 from dyspeptic patients).Of a total of 189 samples,only 6 samples had insufficient material for PCR analysis:1 from mucosa distant from the tumor in a patient with ESCC,3from patients with HNSCC and 2 from patients without cancer.In 183 samples(96.8%)GAPDH,G3PDH and/orβ-globin were amplified,thus indicating the adequacy of the DNA in those samples.HPV DNA was negative in all the 183 samples tested:52 with ESCC,9 with esophagitis and 122 with normal esophageal mucosa.CONCLUSION:There was no evidence of HPV infection in different ESCC from southern Brazil. | Luís Carlos Moreira Antunes Joo Carlos Prolla Antonio de Barros Lopes Marta Pires da Rocha Renato Borges Fagundes | 2013 | World Journal of Gastroenterology2013,19,39: | 4 |
| 14 | Integrating geochemical(surface waters, stream sediments)and biological(diatoms) approaches to assess AMD environmental impact in a pyritic mining area: Aljustrel(Alentejo, Portugal)显示文摘Aljustrel mines were classified as having high environmental hazard due to their large tailings volume and high metal concentrations in waters and sediments.To assess acid mine drainage impacted systems whose environmental conditions change quickly,the use of biological indicators with short generation time such as diatoms is advantageous.This study combined geochemical and diatom data,whose results were highlighted in 3 groups:Group 1,with low p H(1.9–5.1)and high metal/metalloid(Al,As,Cd,Co,Cu,Fe,Mn,Ni,Pb,Zn;0.65–1032 mg/L)and SO_4(405–39124 mg/L)concentrations.An acidophilic species,Pinnularia aljustrelica,was perfectly adapted to the adverse conditions;in contrast,teratological forms of Eunotia exigua were found,showing that metal toxicity affected this species.The low availability of metals/metalloids in sediments of this group indicates that metals/metalloids of the exchangeable fractions had been solubilized,which in fact enables metal/metalloid diatom uptake and consequently the occurrence of teratologies;Group 2,with sites of near neutral p H(5.0–6.8)and intermediate metal/metalloid(0.002–6 mg/L)and SO_4(302–2179 mg/L)concentrations;this enabled the existence of typical species of uncontaminated streams(Brachysira neglectissima,Achnanthidium minutissimum);Group 3,with samples from unimpacted sites,showing low metal/metalloid(0–0.8 mg/L)and SO_4(10–315 mg/L)concentrations,high pH(7.0–8.4)and Cl contents(10–2119 mg/L)and the presence of brackish to marine species(Entomoneis paludosa).For similar conditions of acidity,differences in diversity,abundance and teratologies of diatoms can be explained by the levels of metals/metalloids. | Ana Teresa Luís Nuno Duraes SaloméFernandes Pinheiro de Almeida Eduardo Ferreira da Silva | 2016 | Journal of Environmental Sciences2016,28,4: | 4 |
| 15 | Chronic myeloid leukemia-from the Philadelphia chromosome to specific target drugs:A literature review显示文摘Chronic myeloid leukemia(CML)is a myeloproliferative neoplasm and was the first neoplastic disease associated with a well-defined genotypic anomaly―the presence of the Philadelphia chromosome.The advances in cytogenetic and molecular assays are of great importance to the diagnosis,prognosis,treatment,and monitoring of CML.The discovery of the breakpoint cluster region(BCR)-Abelson murine leukemia(ABL)1 fusion oncogene has revolutionized the treatment of CML patients by allowing the development of targeted drugs that inhibit the tyrosine kinase activity of the BCR-ABL oncoprotein.Tyrosine kinase inhibitors(known as TKIs)are the standard therapy for CML and greatly increase the survival rates,despite adverse effects and the odds of residual disease after discontinuation of treatment.As therapeutic alternatives,the subsequent TKIs lead to faster and deeper molecular remissions;however,with the emergence of resistance to these drugs,immunotherapy appears as an alternative,which may have a cure potential in these patients.Against this background,this article aims at providing an overview on CML clinical management and a summary on the main targeted drugs available in that context. | Mariana Miranda Sampaio Maria Luísa Cordeiro Santos Hanna Santos Marques Vinícius Lima de Souza Gonçalves Glauber Rocha Lima Araújo Luana Weber Lopes Jonathan Santos Apolonio Camilo Santana Silva Luana Kauany de SáSantos Beatriz Rocha Cuzzuol Quézia Estéfani Silva Guimarães Mariana Novaes Santos Breno Bittencourt de Brito Filipe Antônio França da Silva Márcio Vasconcelos Oliveira Cláudio Lima Souza Fabrício Freire de Melo | 2021 | World Journal of Clinical Oncology2021,12,2: | 3 |
| 16 | Physiological Effect of Kinetin on the Photosynthetic Apparatus and Antioxidant Enzymes Activities During Production of Anthurium显示文摘The results observed in the literature raise the hypothesis according to which cytokinin plays important roles in photosynthetic metabolisms and antioxidant enzymes. Thus, the study aimed to evaluate the effect of foliar application of the isolated cytokinin kinetin at the production cycle, seeking to analyze its effects on enzyme activity and photosynthetic parameters. The plants treated with CK presented reduction of leaf CO_2 assimilation rate(Pn) and stomatal conductance(Gs), while that transpiration rate(Tr) was unaffected. The internal CO_2 concentrations decreased with the increase in cytokinin levels, but were maintained under CK 50 mg·L^(-1). The plants treated with CK 75 mg·L^(-1) was verified higher carboxylation efficiency(Pn/Ci), which was associated to values of CO_2 assimilation and transpiration unaltered. Apparent electron transport rate showed variations in the concentration of 25 mg·L^(-1). Considering the study of enzyme activity, on the other hand, it cannot be stated that kinetin has an effective action in delaying oxidative damage. It presents mixed results, since an efficiency in the application of cytokinin was not observed, presenting induction levels of ascorbate peroxidase activity. Thus, further research is needed to determine more precisely the effects of kinetin on gas exchange and antioxidant enzymes in anthurium plants. | de MOURA Fabiana B. VIEIRA Marcos R. da S.

| 17 | Sex-specific effects of Eugenia punicifolia extract on gastric ulcer healing in rats显示文摘AIM To evaluate the sex-specific effects of a hydroalcoholic extract from Eugenia punicifolia(HEEP) leaves on gastric ulcer healing.METHODS In this rat study involving males, intact(cycling) females, and ovariectomized females, gastric ulcers were induced using acetic acid. A vehicle, lansoprazole, or HEEP was administered for 14 d after ulcer induction. Body weight was monitored throughout the treatment period. At the end of treatment, the rats were euthanized and the following in vivo and in vitro investigations were performed: macroscopic examination of the lesion area and organ weights, biochemical analysis, zymography, and evaluation of protein expression levels. Additionally, the concentration-dependent effect of HEEP was evaluated in terms of subacute toxicity and cytotoxicity.RESULTS Compared to the vehicle, HEEP demonstrated a great healing capacity by substantially reducing the ulcerative lesion area in males(52.44%), intact females(85.22%), and ovariectomized females(65.47%), confirming that HEEP accelerates the healing of acetic acidinduced gastric lesions and suggesting that this effect is modulated by female sex hormones. The antiulcer effect of HEEP was mediated by prostaglandin E2 only in male rats. Overall, the beneficial effect of HEEP was the highest in intact females. Notably, HEEP promoted the expression of vascular endothelial growth factor(intact vs ovariectomized females) and decreased the expression of Caspase-8 and Bcl-2(intact female vs male or ovariectomized female). Additionally, HEEP enhanced fibroblast proliferation and migration into a wounded area in vitro, confirming its healing effect. Finally, no sign of subacute toxicity or cytotoxicity of HEEP was observed.CONCLUSION In gastric ulcers, HEEP-induced healing(modulated by female sex hormones; in males, mediated by prostaglandin) involves extracellular matrix remodeling, with gastric mucosa cell proliferation and migration. | Larissa Lucena Périco Vinícius Peixoto Rodrigues Rie Ohara Gabriela Bueno Vania Vasti Alfieri Nunes Raquel Cássia dos Santos Ana Carolina Lima Camargo Luis Antuio Justulin Joior Sérgio Faloni de Andrade Viviane Miranda Bispo Steimbach Luísa Mota da Silva Lúcia Regina Machado da Rocha Wagner Vilegas Catarina dos Santos Clélia Akiko Hiruma-Lima | 2018 | World Journal of Gastroenterology2018,24,38: | 3 |
| 18 | Starch Digestibility and Physicochemical and Cooking Properties of Irradiated Rice Grains显示文摘This study evaluated the starch digestibility, physicochemical properties and cooking characteristics of polished rice(varieties IRGA417 and IAC202) subjected to the doses of 0(as the control), 1, 2 and 5 k Gy of gamma radiation. The highest dose decreased the apparent amylose content, peak viscosity, water absorption and volume expansion. Irradiation increased the solid loss by 119% and 187% for IAC202 and IRGA417, respectively, when comparing the higher dose with the control. For IAC202, irradiation decreased the rapidly digestible starch and increased the slowly digestible starch(SDS) and resistant starch(RS). IRGA417 showed an elevation of SDS and a reduction in RS. And 1 k Gy dose of gamma radiation generated the highest level of RS for both the two varieties and presented the smallest changes in other physicochemical and cooking properties. | Luís Fernando POLESI Manoel Divino da MATTA JUNIOR Silene Bruder Silveira SARMENTO Solange Guidolin CANNIATTI-BRAZACA | 2017 | Rice science2017,24,1: | 3 |

| 20 | Acute fatty liver of pregnancy associated with severe acute pancreatitis:A case report显示文摘Acute fatty liver of pregnancy is a rare disease that affects women in the third trimester of pregnancy. Although infrequent, the disease can cause maternal mortality. The diagnosis is not always clear until the pregnancy is terminated, and significant complications, such as acute pancreatitis, can occur. Pancreatic involvement typically only occurs in severe cases after the development of hepatic and renal impairment. To date, little knowledge is available regarding how the disease causes pancreatitis. Treatment involves supportive measures and pregnancy interruption. In this report, we describe a case of a previously healthy 26-year-old woman at a gestational age of 27 wk and 6 d who was admitted with severe abdominal pain and vomiting. This case illustrates the clinical and laboratory overlap between acute fatty liver of pregnancy and pancreatitis, highlighting the difficulties in differentiating each disease. Furthermore, the hypothesis for this overlapping is presented, and the therapeutic options are discussed. | Cássio Vieira de Oliveira Alecsro Moreira Julio P Baima Leticia de C Franzoni Talles B Lima Fabio da S Yamashiro Kunie Yabuki Rabelo Coelho Ligia Y Sassaki Carlos Antonio Caramori Ferno G Romeiro Giovanni F Silva | 2014 | World Journal of Hepatology2014,6,7: | 3 |
