1Research advances on the multiple uses of Moringa oleifera: a sustainable alternative for socially neglected population显示文摘Moringa oleifera Lam(Moringaceae) is a plant with high nutritional and medicinal value. Native to India, it is now widely distributed throughout tropical and subtropical regions of the world. Its different parts are sources of proteins, vitamins and minerals and present different pharmacological and biotechnological potential. Moreover, M. oleifera seeds are widely used in water and effluent treatment, for their coagulation, flocculation and sedimentation properties, their ability of improving water quality, by reducing organic matter and microbial load, with special applicability in intensive animal production systems, such as aquaculture. In addition, due to its high nutritional value and several medicinal properties, this tree may act as a nutritional and medical alternative for socially neglected populations. In this context, this review gathers information on M. oleifera, emphasizing its chemical constituents, nutritional, pharmacological and antimicrobial properties, applications in the treatment of water effluents, and ecological and social aspects.Raimunda Samia Nogueira Brilhante Jamille Alencar Sales Vandbergue Santos Pereira Débora de Souza Collares Maia Castelo-Branco Rossana de Aguiar Cordeiro Célia Maria de Souza Sampaio Manoel de Araújo Neto Paiva Joao Bosco Feitosa dos Santos JoséJúlio CostaSidrim Marcos Fábio Gadelha Rocha 2017Asian Pacific Journal of Tropical Medicine2017,10,7:10
2Obesity in kidney disease:A heavyweight opponen显示文摘Obesity is an important worldwide challenge that must be faced in most developed and developing countries because of unhealthy nutritional habits.The consequences of obesity and being overweight are observed in different organs,but the kidney is one of the most affected.Excess adipose tissue causes hemodynamic alterations in the kidney that can result in renal disease.However,obesity is also commonly associated with other comorbidities such as chronic inflammation,hypertension and diabetes.This association of several aggravating factors is still a matter of concern in clinical and basic research because the pathophysiologic mechanisms surrounding chronic kidney disease development in obese patients remain unclear.This review will discuss the consequences of obesity in the context of renal injury.Raphael Jose Ferreira Felizardo Marina Burgos da Silva Cristhiane Favero Aguiar Niels Olsen Saraiva Camara 2014World Journal of Nephrology2014,3,3:7
3Enamel microabrasion: An overview of clinical and scientific considerations显示文摘Superficial stains and irregularities of the enamelare generally what prompt patients to seek dental intervention to improve their smile. These stains or defects may be due to hypoplasia, amelogenesis imperfecta, mineralized white spots, or fluorosis, for which enamel microabrasion is primarily indicated. Enamel microabrasion involves the use of acidic and abrasive agents, such as with 37% phosphoric acid and pumice or 6% hydrochloric acid and silica, applied to the altered enamel surface with mechanical pressure from a rubber cup coupled to a rotatory mandrel of a lowrotation micromotor. If necessary, this treatment can be safely combined with bleaching for better esthetic results. Recent studies show that microabrasion is a conservative treatment when the enamel wear is minimal and clinically imperceptible. The most important factor contributing to the success of enamel microabrasion is the depth of the defect, as deeper, opaque stains, such as those resulting from hypoplasia, cannot be resolved with microabrasion, and require a restorative approach. Surface enamel alterations that result from microabrasion, such as roughness and microhardness, are easily restored by saliva. Clinical studies support the efficacy and longevity of this safe and minimally invasive treatment. The present article presents the clinical and scientific aspects concerning the microabrasion technique, and discusses the indications for and effects of the treatment, including recent works describing microscopic and clinical evaluations.Núbia Inocencya Pavesi Pini Daniel Sundfeld-Neto Flavio Henrique Baggio Aguiar Renato Herman Sundfeld Luis Roberto Marcondes Martins José Roberto Lovadino Débora Alves Nunes Leite Lima 2015World Journal of Clinical Cases2015,3,1:6
4Bone marrow-derived monocyte infusion improves hepatic fibrosis by decreasing osteopontin,TGF-β1,IL-13 and oxidative stress显示文摘AIM To evaluate the therapeutic effects of bone marrowderived CD11b+CD14+ monocytes in a murine model of chronic liver damage. METHODS Chronic liver damage was induced in C57BL/6 mice by administration of carbon tetrachloride and ethanol for 6 mo. Bone marrow-derived monocytes isolated by immunomagnetic separation were used for therapy. The cell transplantation effects were evaluated by morphometry,biochemical assessment,immunohistochemistry and enzyme-linked immunosorbent assay. RESULTS CD11b+CD14+ monocyte therapy significantly reduced liver fibrosis and increased hepatic glutathione levels. Levels of pro-inflammatory cytokines,including tumor necrosis factor-α,interleukin(IL)-6 and IL-1β,in addition to pro-fibrotic factors,such as IL-13,transforming growth factor-β1 and tissue inhibitor of metalloproteinase-1 also decreased,while IL-10 and matrix metalloproteinase-9 increased in the monocytetreated group. CD11b+CD14+ monocyte transplantation caused significant changes in the hepatic expression of α-smooth muscle actin and osteopontin. CONCLUSION Monocyte therapy is capable of bringing about improvement of liver fibrosis by reducing oxidative stress and inflammation,as well as increasing antifibrogenic factors.Veruska Cintia Alexandrino de Souza Thiago Almeida Pereira Valéria Wanderley Teixeira Helotonio Carvalho Maria Carolina Accioly Brelaz de Castro Carolline Guimaraes D’assuncao Andreia Ferreira de Barros Camila Lima Carvalho Virgínia Maria Barros de Lorena Vláudia Maria Assis Costa Alvaro Aguiar Coelho Teixeira Regina Celia Bressan Queiroz Figueiredo Sheilla Andrade de Oliveira 2017World Journal of Gastroenterology2017,23,28:6
5Postpartum depression:A systematic review of the genetics involved显示文摘Postpartum depression is one of the most prevalent psychopathologies. Its prevalence is estimated to be between 10% and 15%. Despite its multifactorial etiology, it is known that genetics play an important role in the genesis of this disorder. This paper reviews epidemiological evidence supporting the role of genetics in postpartum depression(PPD). The main objectives of this review are to determine which genes and polymorphisms are associated with PPD and discuss how this association may occur. In addition, this paper explores whether these genes are somehow related to or even the same as those linked to Major Depression(MD). To identify gaps in the current knowledge that require investigation, a systematic review was conducted in the electronic databases Pub Med, LILACS and Sci ELO using the index terms 'postpartum depression' and 'genetics'. Literature searches for articles in peerreviewed journals were made until April 2014. PPD was indexed 56 times with genetics. The inclusion criteria were articles in Portuguese, Spanish or English that were available by institutional means or sent by authors upon request; this search resulted in 20 papers. Genes and polymorphisms traditionally related to MD, which are those involved in the serotonin, catecholamine, brain-derived neurotrophic factor and tryptophan metabolism, have been the most studied, and some have been related to PPD. The results are conflicting and some depend on epigenetics, which makes the data incipient. Further studies are required to determine the genes that are involved in PPD and establish the nature of the relationship between these genes and PPD.Tiago Castro e Couto Mayra Yara Martins Brancaglion António Alvim-Soares Lafaiete Moreira Frederico Duarte Garcia Rodrigo Nicolato Humberto Corrêa Regina Amélia Lopes P Aguiar Henrique Vitor Leite 2015World Journal of Psychiatry2015,5,1:5
6RNAi mechanisms in Huntington’s disease therapy:siRNA versus shRNA显示文摘Huntington’s Disease(HD)is a genetically dominant trinucleotide repeat disorder resulting from CAG repeats within the Huntingtin(HTT)gene exceeding a normal range(>36 CAGs).Symptoms of the disease manifest in middle age and include chorea,dystonia,and cognitive decline.Typical latency from diagnosis to death is 20 years.There are currently no disease-modifying therapies available to HD patients.RNAi is a potentially curative therapy for HD.A popular line of research employs siRNA or antisense oligonucleotides(ASO)to knock down mutant Huntingtin mRNA(mHTT).Unfortunately,this modality requires repeated dosing,commonly exhibit off target effects(OTEs),and exert renal and hepatic toxicity.In contrast,a single AAV-mediated short-hairpin RNA(shRNA)dose can last years with low toxicity.In addition,we highlight research indicating that shRNA elicits fewer OTEs than siRNA when tested head-tohead.Despite this promise,shRNA therapy has been held back by difficulties controlling expression(oversaturating cells with toxic levels of RNA construct).In this review,we compare RNAi modalities for HD and propose novel methods of optimizing shRNA expression and on-target fidelity.Sebastian Aguiar Bram van der Gaag Francesco Albert Bosco Cortese 2017Translational Neurodegeneration2017,6,1:3

10Influence of donor age on the differentiation and division capacity of human adipose-derived stem cells显示文摘BACKGROUND Human adipose-derived stromal/stem cells(hASCs)are one of the most useful types of mesenchymal stromal/stem cells,which are adult multipotent cells with great therapeutic potential for the treatment of several diseases.However,for successful clinical application,it is critical that high-quality cells can be obtained.Diverse factors seem to be able to influence cell quality and performance,especially factors related to donors’intrinsic characteristics,such as age.Nevertheless,there is no consensus regarding this characteristic,and there is conflicting information in the literature.AIM To investigate the growth kinetics and differentiation potential of adipose-derived stem cells isolated from the lipoaspirates of elderly and young donors.METHODS hASCs were harvested from liposuctioned adipose tissue obtained from female donors(aged 20-70 years).Cells were distributed into two groups according to age range:old hASCs(oASCs,≥55 years,n=9)and young hASCs(yASCs,≤35 years,n=9).For each group,immunophenotypic characterization was performed by flow cytometry.Population doubling time was assessed over seven days.For adipogenic potential evaluation,lipid deposits were assessed after 7 d,14 d and 21 d of adipogenic induction.Osteogenic potential was verified by analyzing cell mineralization after 14 d,21 d and 28 d of osteogenic induction.mRNA expression of PPARγ2,CEBPA and Runx2 were detected by quantitative reverse transcription polymerase chain reaction.RESULTS hASCs were successfully obtained,cultured,and grouped according to their age:yASCs(26.33±4.66 years old)and oASCs(64.78±4.58 years old).After maintenance of the cells in culture,there were no differences in morphology between cells from the young and old donors.Additionally,both groups showed classical immunophenotypic characteristics of mesenchymal stem/stromal cells.The average doubling time indicated that yASCs(4.09±0.94 d)did not significantly differ from oASCs(4.19±1.29 d).Concerning differentiation potential,after adipogenic and osteogenic induction,yASCs and oASCs were able to differentiate to greater levels than the noninduced control cells.However,no differences were found in the differentiation efficiency of yASCs and oASCs in adipogenesis or osteogenesis.Additionally,the mRNA expression of PPARγ2,CEBPA and Runx2 were similar in yASCs and oASCs.CONCLUSION Our findings suggest that age does not seem to significantly affect the cell division or adipogenic or osteogenic differentiation ability of adipose-derived stem cells isolated from lipoaspirates.Cintia DS Horinouchi María Julia Barisón Anny W Robert Crisciele Kuligovski Alessandra M Aguiar BrunoDallagiovanna 2020World Journal of Stem Cells2020,12,12:2
11Interleukin-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 2020World Journal of Hepatology2020,12,4:2
