| 2 | Intestinal bile acid physiology and pathophysiology显示文摘Bile acids (BAs) have a long established role in fat digestion in the intestine by acting as tensioactives, due to their amphipatic characteristics. BAs are reabsorbed very efficiently by the intestinal epithelium and recycled back to the liver via transport mechanisms that have been largely elucidated. The transport and synthesis of BAs are tightly regulated in part by specific plasma membrane receptors and nuclear receptors. In addition to their primary effect, BAs have been claimed to play a role in gastrointestinal cancer, intestinal inflammation and intestinal ionic transport. BAs are not equivalent in any of these biological activities, and structural requirements have been generally identified. In particular, some BAs may be useful for cancer chemoprevention and perhaps in inflammatory bowel disease, although further research is necessary in this field. This review covers the most recent developments in these aspects of BA intestinal biology. | Olga Martínez-Augustin Fermín Sánchez de Medina | 2008 | World Journal of Gastroenterology2008，14，37： | 7 |
| 3 | Aminoguanidine impedes human pancreatic tumor growth and metastasis development in nude mice显示文摘AIM:To study the action of aminoguanidine on pancreatic cancer xenografts in relation to cell proliferation,apoptosis,redox status and vascularization.METHODS:Xenografts of PANC-1 cells were developed in nude mice. The animals were separated into two groups:control and aminoguanidine treated. Tumor growth,survival and appearance of metastases were determined in vivo in both groups. Tumors were excised and ex vivo histochemical studies were performed. Cell growth was assessed by Ki-67 expression. Apoptosis was studied by intratumoral expression of B cell lymphoma-2 protein (Bcl-2) family proteins and Terminal deoxynucleotidyl transferase biotin-dUTP Nick End Labeling (Tunel). Redox status was evaluated by the expression of endothelial nitric oxide synthase (eNOS),catalase,copper-zinc superoxide dismutase (CuZnSOD),manganese superoxide dismutase (MnSOD) and glutathione peroxidase (GPx). Finally,vascularization was determined by Massons trichromic staining,and by VEGF and CD34 expression.RESULTS:Tumor volumes after 32 d of treatment by aminoguanidine (AG) were significantly lower than in control mice (P < 0.01). Median survival of AG mice was significantly greater than control animals (P < 0.01). The appearance of both homolateral and contralateral palpable metastases was significantly delayed in AG group. Apoptotic cells,intratumoral vascularization (trichromic stain) and the expression of Ki-67,Bax,eNOS,CD34,VEGF,catalase,CuZnSOD and MnSOD were diminished in AG treated mice (P < 0.01),while the expression of Bcl-2 and GPx did not change.CONCLUSION:The antitumoral action of aminoguanidine is associated with decreased cell proliferation,reduced angiogenesis,and reduced expression of antioxidant enzymes. | Nora A Mohamad Graciela P Cricco Lorena A Sambuco Máximo Croci Vanina A Medina Alicia S Gutiérrez Rosa M Bergoc Elena S Rivera Gabriela A Martín | 2009 | World Journal of Gastroenterology2009，15，9： | 3 |
| 4 | Multimodality functional imaging using DW-MRI and 18F-FDG-PET/CT during radiation therapy for human papillomavirus negative head and neck squamous cell carcinoma: Meixoeiro Hospital of Vigo Experience显示文摘AIM To noninvasively investigate tumor cellularity measured using diffusion-weighted magnetic resonance imaging(DW-MRI) and glucose metabolism measured by 18 Flabeled fluorodeoxyglucose positron emission tomography/computed tomography(18F-FDG-PET/CT) during radiation therapy(RT) for human papillomavirus negative(HPV-) head and neck squamous cell carcinoma(HNSCC).METHODS In this prospective study, 6 HPV- HNSCC patients underwent a total of 34 multimodality imaging examinations(DW-MRI at 1.5 T Philips MRI scanner [(n = 24) pre-, during-(2-3 wk), and post-treatment(Tx), and 18F-FDG PET/CT pre- and post-Tx(n = 10)]. All patients received RT. Monoexponential modeling of the DW-MRI data yielded the imaging metric apparent diffusion coefficient(ADC) and the mean of standardized uptake value(SUV) was measured from 18F-FDG PET uptake. All patients had a clinical follow-up as the standard of care and survival status was documented at 1 year.RESULTS There was a strong negative correlation between the mean of pretreatment ADC(ρ =-0.67, P = 0.01) and the pretreatment 18F-FDG PET SUV. The percentage(%) change in delta(?) ADC for primary tumors and neck nodal metastases between pre- and Wk2-3 Tx were as follows: 75.4% and 61.6%, respectively, for the patient with no evidence of disease, 27.5% and 32.7%, respectively, for those patients who were alive with disease, and 26.9% and 7.31%, respectively, for those who were dead with disease.CONCLUSION These results are preliminary in nature and are indicative, and not definitive, trends rendered by the imaging metrics due to the small sample size of HPV- HNSCC patients in a Meixoeiro Hospital of Vigo Experience. | David Aramburu Núnez Antonio Lopez Medina Moisés Mera Iglesias Francisco Salvador Gomez Abhay Dave Vaios Hatzoglou Ramesh Paudyal Alfonso Calzado Joseph O Deasy Amita Shukla-Dave Victor M Munoz | 2017 | World Journal of Radiology2017，9，1： | 2 |
| 5 | Current systematic reviews and meta-analyses of COVID-19显示文摘BACKGROUND Coronavirus disease 2019(COVID-19)has left a significant impact on the world's health,economic and political systems;as of November 20,2020,more than 57 million people have been infected worldwide,with over 1.3 million deaths.While the global spotlight is currently focused on combating this pandemic through means ranging from finding a treatment among existing therapeutic agents to inventing a vaccine that can aid in halting the further loss of life.AIM To collect all systematic reviews and meta-analyses published related to COVID-19 to better identify available evidence,highlight gaps in knowledge,and elucidate further meta-analyses and umbrella reviews that are yet to be performed.METHODS We explored studies based on systematic reviews and meta-analyses with the keyterms,including severe acute respiratory syndrome(SARS),SARS virus,coronavirus disease,COVID-19,and SARS coronavirus-2.The included studies were extracted from Embase,Medline,and Cochrane databases.The publication timeframe of included studies ranged between January 01,2020,to October 30,2020.Studies that were published in languages other than English were not considered for this systematic review.The finalized full-text articles are freely accessible in the public domain.RESULTS Searching Embase,Medline,and Cochrane databases resulted in 1906,669,and 19 results,respectively,that comprised 2594 studies.515 duplicates were subsequently removed,leaving 2079 studies.The inclusion criteria were systematic reviews or meta-analyses.860 results were excluded for being a review article,scope review,rapid review,panel review,or guideline that produced a total of 1219 studies.After screening articles were categorized,the included articles were put into main groups of clinical presentation,epi-demiology,screening and diagnosis,severity assessment,special populations,and treatment.Subsequently,there was a second subclassification into the following groups:gastrointestinal,cardiovascular,neurological,stroke,thrombosis,anosmia and dysgeusia,ocular manifestations,nephrology,cutaneous manifestations,D-dimer,lymphocyte,anticoagulation,antivirals,convalescent plasma,immunosuppressants,corticosteroids,hydroxychloroquine,renin-angiotensin-aldosterone system,technology,diabetes mellitus,obesity,pregnancy,children,mental health,smoking,cancer,and transplant.CONCLUSION Among the included articles,it is clear that further research is needed regarding treatment options and vaccines.With more studies,data will be less heterogeneous,and statistical analysis can be better applied to provide more robust clinical evidence.This study was not designed to give recommendations regarding the management of COVID-19. | Mahmoud Nassar Nso Nso Mostafa Alfishawy Anastasia Novikov Salim Yaghi Luis Medina Bahtiyar Toz Sofia Lakhdar Zarwa Idrees Yungmin Kim Dawa Ongyal Gurung Raheel S Siddiqui David Zheng Mariam Agladze Vikram Sumbly Jasmine Sandhu Francisco Cuevas Castillo Nadya Chowdhury Ravali Kondaveeti Sakil Bhuiyan Laura Guzman Perez Riki Ranat Carlos Gonzalez Harangad Bhangoo John Williams Alaa Eldin Osman Joyce Kong Jonathan Ariyaratnam Mahmoud Mohamed Ismail Omran Mariely Lopez Akwe Nyabera Ian Landry Saba Iqbal Anoosh Zafar Gondal Sameen Hassan Ahmed Daoud Bahaaeldin Baraka Theo Trandafirescu Vincent Rizzo | 2021 | World Journal of Virology2021，10，4： | 2 |
