| 2 | Neurodegeneration:An early event of diabetic retinopathy显示文摘Diabetic retinopathy(DR) has been classically considered to be a microcirculatory disease of the retina caused by the deleterious metabolic effects of hyperglycemia per se and the metabolic pathways triggered by hyperglycemia.However,retinal neurodegeneration is already present before any microcirculatory abnormalities can be detected in ophthalmoscopic examination.In other words,retinal neurodegeneration is an early event in the pathogenesis of DR which predates and participates in the microcirculatory abnormalities that occur in DR.Therefore,the study of the mechanisms that lead to neurodegeneration will be essential to identify new therapeutic targets in the early stages of DR.Elevated levels of glutamate and the overexpression of the renin-angiotensin-system play an essential role in the neurodegenerative process that occurs in diabetic retina.Among neuroprotective factors,pigment epithelial derived factor,somatostatin and erythropoietin seem to be the most relevant and these will be considered in this review.Nevertheless,it should be noted that the balance between neurotoxic and neuroprotective factors rather than levels of neurotoxic factors alone will determine the presence or absence of retinal neurodegeneration in the diabetic eye.New strategies,based on either the delivery of neuroprotective agents or the blockade of neurotoxic factors,are currently being tested in experimental models and in clinical pilot studies.Whether these novel therapies will eventually supplement or prevent the need for laser photocoagulation or vitrectomy awaits the results of additional clinical research. | Marta Villarroel Andreea Ciudin Cristina Hernández Rafael Simó | 2010 | World Journal of Diabetes2010,1,2: | 41 |

| 6 | Intestinal microbiota in health and disease: Role of bifidobacteria in gut homeostasis显示文摘The pool of microbes inhabiting our body is known as 'microbiota' and their collective genomes as 'microbiome'. The colon is the most densely populated organ in the human body, although other parts, such as the skin, vaginal mucosa, or respiratory tract, also harbour specific microbiota. This microbial community regulates some important metabolic and physiological functions of the host, and drives the maturation of the immune system in early life, contributing to its homeostasis during life. Alterations of the intestinal microbiota can occur by changes in composition(dysbiosis), function, or microbiota-host interactions and they can be directly correlated with several diseases. The only disease in which a clear causal role of a dysbiotic microbiota has been demonstrated is the case of Clostridium difficile infections. Nonetheless, alterations in composition and function of the microbiota have been associated with several gastrointestinal diseases(inflammatory bowel disease, colorectal cancer, or irritable bowel syndrome), as well as extra-intestinal pathologies, such as those affecting the liver, or the respiratory tract(e.g., allergy, bronchial asthma, and cystic fibrosis), among others. Species of Bifidobacterium genus are the normal inhabitants of a healthy human gut and alterations in number and composition of their populations is one of the most frequent features present in these diseases. The use of probiotics, including bifidobacteria strains, in preventive medicine to maintain a healthy intestinal function is well documented. Probiotics are also proposed as therapeutic agents for gastrointestinal disorders and other pathologies. The World Gastroenterology Organization recently published potential clinical applications for several probiotic formulations, in which species of lactobacilli are predominant. This review is focused on probiotic preparations containing Bifidobacterium strains, alone or in combination with other bacteria, which have been tested in human clinical studies. In spite of extensive literature on and research into this topic, the degree of scientific evidence of the effectiveness of probiotics is still insufficient in most cases. More effort need to be made to design and conduct accurate human studies demonstrating the efficacy of probiotics in the prevention, alleviation, or treatment of different pathologies. | Rafael Tojo Adolfo Suárez Marta G Clemente Clara G de los Reyes-Gavilán Abelardo Margolles Miguel Gueimonde Patricia Ruas-Madiedo | 2014 | World Journal of Gastroenterology2014,20,41: | 33 |

| 9 | Advances in immunotherapy for treatment of lung cancer显示文摘Different approaches for treating lung cancer have been developed over time, including chemotherapy, radiotherapy and targeted therapies against activating mutations. Lately, better understanding of the role of the immunological system in tumor control has opened multiple doors to implement different strategies to enhance immune response against cancer cells. It is known that tumor cells elude immune response by several mechanisms. The development of monoclonal antibodies against the checkpoint inhibitor programmed cell death protein 1(PD-1) and its ligand(PD-L1), on T cells, has led to high activity in cancer patients with long lasting responses. Nivolumab, an anti PD-1 inhibitor, has been recently approved for the treatment of squamous cell lung cancer patients, given the survival advantage demonstrated in a phase III trial. Pembrolizumab, another anti PD-1 antibody, has received FDA breakthrough therapy designation for treatment of non-small cell lung cancer(NSCLC), supported by data from a phase I trial. Clinical trials with anti PD-1/PD-L1 antibodies in NSCLC have demonstrated very good tolerability and activity, with response rates around 20% and a median duration of response of 18 months. | Jean G.Bustamante Alvarez María González-Cao Niki Karachaliou Mariacarmela Santarpia Santiago Viteri Cristina Teixidó Rafael Rosell | 2015 | Cancer Biology & Medicine2015,12,3: | 22 |
| 10 | China’s 1-3-7 surveillance and response strategy for malaria elimination: Is case reporting, investigation and foci response happening according to plan?显示文摘Background:The China’s 1-3-7 strategy was initiated and extensively adopted in different types of counties(geographic regions)for reporting of malaria cases within 1 day,their confirmation and investigation within 3 days,and the appropriate public health response to prevent further transmission within 7 days.Assessing the level of compliance to the 1-3-7 strategy at the county level is a first step towards determining whether the surveillance and response strategy is happening according to plan.This study assessed if the time-bound targets of the 1-3-7 strategy were being sustained over time.Such information would be useful to improve implementation of the 1-3-7 strategy in China.Methods:This cross-sectional study involved country-wide programmatic data for the period January 1st 2013 to June 30th 2014.Data variables were extracted from the national malaria information system and included socio-demographic information,type of county,date of diagnosis,date of reporting,date of case investigation,case classification(indigenous,or imported,or unknown),focus investigation,date of reactive case detection(RACD),and date of indoor residual spraying(IRS).Summary statistics and proportions were used and comparisons between groups were assessed using the chi-square test.Level of significance was set at a P-value≤0.05.Results:Of a total of 5,688 malaria cases from 731 counties,there were 55(1%)indigenous cases(only in Type 1 and Type 2 counties)and 5,633(99%)imported cases from all types of counties.There was no delay in reporting malaria cases by type of county.In terms of case investigation,97.5%cases were investigated within 3 days with the proportion of delays(1.5%)in type 2 counties,being significantly lower than type 1 counties(4.1%).Regarding active foci,96.4%were treated by RACD and/or IRS.Conclusions:The performance of 1-3-7 strategy was encouraging but identified some challenges that if addressed can further improve implementation. | Shui-Sen Zhou Shao-Sen Zhang Li Zhang Aafje ECRietveld Andrew RRamsay Rony Zachariah Karen Bissell Rafael Van den Bergh Zhi-Gui Xia Xiao-Nong Zhou Richard ECibulskis | 2015 | Infectious Diseases of Poverty2015,4,1: | 21 |
| 11 | Long-term outcomes of hepatocellular carcinoma that underwent chemoembolization for bridging or downstaging显示文摘BACKGROUND Prospective study of 200 patients with hepatocellular carcinoma(HCC)that underwent liver transplant(LT)after drug-eluting beads transarterial chemoembolization(DEB-TACE)for downstaging versus bridging.Overall survival and tumor recurrence rates were calculated,eligibility for LT,time on the waiting list and radiological response were compared.After TACE,only patients within Milan Criteria(MC)were transplanted.More patients underwent LT in bridging group.Five-year post-transplant overall survival,recurrence-free survival has no difference between the groups.Complete response was observed more frequently in bridging group.Patients in DS group can achieve posttransplant survival and HCC recurrence-free probability,at five years,just like patients within MC in patients undergoing DEB-TACE.AIM To determine long-term outcomes of patients with HCC that underwent LT after DEB-TACE for downstaging vs bridging.METHODS Prospective cohort study of 200 patients included from April 2011 through June 2014.Bridging group included patients within MC.Downstaging group(out of MC)was divided in 5 subgroups(G1 to G5).Total tumor diameter was≤8 cm for G1,2,3,4(n=42)and was>8 cm for G5(n=22).Downstaging(n=64)and bridging(n=136)populations were not significantly different.Overall survival and tumor recurrence rates were calculated by the Kaplan-Meier method.Additionally,eligibility for LT,time on the waiting list until LT and radiological response were compared.RESULTS After TACE,only patients within MC were transplanted.More patients underwent LT in bridging group 65.9%(P=0.001).Downstaging population presented:higher number of nodules 2.81(P=0.001);larger total tumor diameter 8.09(P=0.001);multifocal HCC 78%(P=0.001);more post-transplantation recurrence 25%(P=0.02).Patients with maximal tumor diameter up to 7.05 cm were more likely to receive LT(P=0.005).Median time on the waiting list was significantly longer in downstaging group 10.6 mo(P=0.028).Five-year posttransplant overall survival was 73.5%in downstaging and 72.3%bridging groups(P=0.31),and recurrence-free survival was 62.1%in downstaging and 74.8%bridging groups(P=0.93).Radiological response:complete response was observed more frequently in bridging group(P=0.004).CONCLUSION Tumors initially exceeding the MC down-staged after DEB-TACE,can achieve post-transplant survival and HCC recurrence-free probability,at five years,just like patients within MC in patients undergoing DEB-TACE. | Breno Boueri Affonso Francisco Leonardo Galastri Joaquim Mauricio da Motta Leal Filho Felipe Nasser Priscila Mina Falsarella Rafael Noronha Cavalcante Marcio Dias de Almeida Guilherme Eduardo Goncalves Felga Leonardo Guedes Moreira Valle Nelson Wolosker | 2019 | World Journal of Gastroenterology2019,25,37: | 21 |
| 12 | Elastography-based screening for esophageal varices in patients with advanced chronic liver disease显示文摘Elastography-based liver stiffness measurement(LSM) is a non-invasive tool for estimating liver fibrosis but also provides an estimate for the severity of portal hypertension in patients with advanced chronic liver disease(ACLD). The presence of varices and especially of varices needing treatment(VNT) indicates distinct prognostic stages in patients with compensated ACLD(cACLD). The Baveno VI guidelines suggested a simple algorithm based on LSM < 20 kPa(by transient elastography, TE) and platelet count > 150 G/L for ruling-out VNT in patients with cACLD. These(and other) TE-based LSM cut-offs have been evaluated for VNT screening in different liver disease etiologies. Novel point shear-wave elastography(pSWE) and two-dimensional shear wave elastography(2D-SWE) methodologies for LSM have also been evaluated for their ability to screen for 'any' varices and for VNT. Finally, the measurement of spleen stiffness(SSM) by elastography(mainly by pSWE and 2D-SWE) may represent another valuable screening tool for varices. Here, we summarize the current literature on elastography-based prediction of 'any' varices and VNT. Finally,we have summarized the published LSM and SSM cut-offs in clinically useful scale cards. | Rafael Paternostro Thomas Reiberger Theresa Bucsics | 2019 | World Journal of Gastroenterology2019,25,3: | 20 |
| 13 | Effects of creep feeding and supplemental glutamine or glutamine plus glutamate (Aminogut) on pre- and post-weaning growth performance and intestinal health of piglets显示文摘Background: Creep feeding is used to stimulate piglet post-weaning feed consumption.L-Glutamine(GLN) is an important source of fuel for intestinal epithelial cells.The objective of this study was to determine the impact of creep feeding and adding GLN or AminoGut(AG;containing glutamine + glutamate) to pre-and post-weaning diets on pig performance and intestinal health.Litters(N = 120) were allotted to four treatments during 14–21 d of lactation: 1) No creep feed(NC,n = 45);2) creep fed control diet(CFCD,n = 45);3) creep fed 1% GLN(CFGLN,n = 15);4) creep fed.88% AG(CFAG,n = 15).After weaning,the NC and CFCD groups were sub-divided into three groups(n = 15 each),receiving either a control nursery diet(NC-CD,CFCD-CD) or a diet supplemented with either GLN(NC-GLN,CFCD-GLN) or with AG(NC-AG,CFCD-AG).Litters that were creep fed with diets containing GLN or AG also were supplemented with those amino acids in the nursery diets(CFGLN-GLN,CFAG-AG).Glutamine was added at 1% in all three post-weaning diet phases and AG was added at.88% in phase 1 and 2 and at.66% in phase 3.Results: Feed conversion(feed/gain) showed means among treatment means close to significance(P = 0.056) and Tukey's test for pairwise mean comparisons showed that Pigs in the CFGLN-GLN group had the best feed conversion(feed/gain) in the first three-week period post-weaning,exceeding(P = 0.044) controls(CFCD-CD) by 34%.The NC-AG group had(P = 0.02) the greatest feed intake in the last three week of the study,exceeding controls(CFCD-CD) by 12%.CFGLN-GLN,CFCD-GLN and sow reared(SR) pigs had the greatest(P = 0.049) villi height exceeding the CFCD-AG group by 18%,20% and 19% respectively.The CFAG-AG group had the deepest(P = 0.001) crypts among all treatments.CFGLN-GLN,CFCD-GLN and SR groups had the greatest(P = 0.001) number of cells proliferating(PCNA) exceeding those in the NC-CD group by 43%,54% and 63% respectively.Sow reared pigs showed the greatest(P = 0.001) intestinal absorption capacity for xylose and mannitol.Conclusion: Supplementation of creep feed and nursery diets with GLN and/or AminoGut in the first three week improved feed conversion possibly due to improved intestinal health. | Rafael A Cabrera James L Usry Consuelo Arrellano Eduardo T Nogueira Marianne Kutschenko Adam J Moeser Jack Odle | 2013 | Journal of Animal Science and Biotechnology2013,4,3: | 17 |

| 16 | Exercise-induced oxidative stress:Friend or foe?显示文摘The first report demonstrating that prolonged endurance exercise promotes oxidative stress in humans was published more than 4 decades ago.Since this discovery,many ensuing investigations have corroborated the fact that muscular exercise increases the production of reactive oxygen species(ROS)and results in oxidative stress in numerous tissues including blood and skeletal muscles.Although several tissues may contribute to exercise-induced ROS production,it is predicted that muscular contractions stimulate ROS production in active muscle fibers and that skeletal muscle is a primary source of ROS production during exercise.This contraction-induced ROS generation is associated with(1)oxidant damage in several tissues(e.g.,increased protein oxidation and lipid peroxidation),(2)accelerated muscle fatigue,and(3)activation of biochemical signaling pathways that contribute to exercise-induced adaptation in the contracting muscle fibers.While our understanding of exercise and oxidative stress has advanced rapidly during the last decades,questions remain about whether exercise-induced increases in ROS production are beneficial or harmful to health.This review addresses this issue by discussing the site(s)of oxidant production during exercise and detailing the health consequences of exercise-induced ROS production. | Scott K.Powers Rafael Deminice Mustafa Ozdemir Toshinori Yoshihara Matthew P.Bomkamp Hayden Hyatt | 2020 | Journal of Sport and Health Science2020,9,5: | 13 |

| 18 | COX-2 in liver,from regeneration to hepatocarcinogenesis:What we have learned from animal models?显示文摘The use of animals lacking genes or expressing genes under the control of cell-specific promoters has signifi cantly increased our knowledge of the genetic and molecular basis of physiopathology,allowing testing of functional hypotheses and validation of biochemical and pharmacologic approaches in order to understand cell function.However,with unexpected frequency,gene knockout animals and,more commonly,animal models of transgenesis give experimental support to even opposite conclusions on gene function.Here we summarize what we learned on the role of cyclooxygenase 2(COX-2) in liver and revise the results obtained in 3 independent models of mice expressing a COX-2 transgene specifi cally in the hepatocyte.Upon challenge with pro-inflammatory stimuli,the animals behave very differently,some transgenic models having a protective effect but others enhancing the injury.In addition,one transgene exerts differential effects on normal liver physiology depending on the transgenic animal model used. | Paloma Martín-Sanz Rafael Mayoral Marta Casado Lisardo Boscá | 2010 | World Journal of Gastroenterology2010,16,12: | 12 |
