MVPA and SB were objectively measured using accelerometry. Adolescents were divided into 4 categories according to MVPA(meeting or not meeting the international recommendations) and the median of SB time(above or below sex-and age-specific median) as follows: High-SB & Inactive, Low-SB & Inactive,High-SB & Active, and Low-SB & Active. A clustered cardiometabolic risk score was computed using the homeostatic model assessment, systolic blood pressure, triglycerides, total cholesterol/high-density lipoprotein cholesterol, sum 4 skinfolds, and cardiorespiratory fitness(CRF).Analyses of covariance were performed to discern differences on cardiometabolic risk scores among PA categories and each health component.Results: The cardiometabolic risk score was lower in adolescents meeting the MVPA recommendation and with less time spent in SB in comparison to the high-SB & Inactive group(p < 0.05). However, no difference in cardiometabolic risk score was established between High-SB or Low-SB groups in inactive adolescents. It is important to note that CRF was the only variable that showed a significant modification(higher)when children were compared from the category of physically inactive with "active" but not from high-to low-SB.Conclusion: Being physically active is the most significant and protective outcome in adolescents to reduce cardiometabolic risk. Lower SB does not exhibit a significant and extra beneficial difference.展开更多

This study was designed to investigate the induction of Nrf2-mediated antioxidant enzymes by combining doses of CUR and SFN and the effect of their combination on the Nrf2-ARE (antioxidant response element) response in HepG2-C8 cells. We hypothesized that the combination of the polyphenol CUR and the isothiocyanate SFN could enhance the induction of AREs and Nrf2-target enzymes. HepG2-C8 cells were treated with a combination of low doses of CUR, SFN or both. The induction of Nrf2-mediated antioxidant and phase II detoxifying enzymes-heme oxygenase-1 (HO-I) and UDP-glucuronosyltransferase-1A (UGT1A)-was measured by real-time RT-PCR and western blotting. ARE-luciferase activity was also quantified. Low doses of CUR (10 ~tM) and SFN (12.5 ~tM) significantly induced the expression of HO-1 and UGT 1 A1 proteins. Through the use of chemical inhibitors of mRNA and protein synthesis, the combination of CUR and SFN was shown to affect the transcriptional regulation of both HO-1 and UGT1A1. Additionally, the combination of CUR and SFN synergistically induced the expression of Nrf2- and ARE-luciferase activity in HepG2-C8 cells. Thus, CUR and SFN at low concentrations augment therapeutic effects in HepG2-C8 cells. The enhanced ARE-luciferase activity of combined CUR and SFN treatment could partly explain the significant induction of the Nrf2-target enzymes HO-1 and UGT1A1. Taken together, our results suggest that combining low doses of CUR and SNF could be a promising strategy for cancer chemoprevention in humans.展开更多

XP patients frequently exhibit neurological degeneration, but the underlying mechanism is unknown, in part due to lack of proper disease models. Here, we generated patientspecific induced pluripotent stem cells (iPSCs) harboring mutations in five different XP genes including XPA, XPB, XPC, XPG, and XPV. These iPSCs were further differentiated to neural cells, and their susceptibility to DNA damage stress was investigated. Mutation of XPA in either neural stem cells (NSCs) or neurons resulted in severe DNA damage repair defects, and these neural cells with mutant XPA were hyper-sensitive to DNA damage-induced apoptosis. Thus, XP-mutant neural cells represent valuable tools to clari the molecular mechanisms of neurological abnormalities in the XP patients.展开更多

文摘Following a large-scale phylogenetic study of the lichenized genus Cora(Basidiomycota:Agaricales:Hygrophoraceae),we formally describe 70 new species,honouring the seventieth birthday of David Leslie Hawksworth,one of the preeminent figures in mycology and lichenology in the past 50 years.Based on an updated phylogeny using the ITS fungal barcoding locus,we now recognize 189 taxa in a genus that until recently was considered to represent a single species;including this contribution,92 of these are formally recognized,including five taxa based on historical names or collections that have not been sequenced.Species of Cora can be recognized by a combination of morphological(size,colour,lobe configuration,surface hairs,hymenophore size and shape),anatomical(thallus thickness,cortex structure,photobiont type,hyphal papillae),and ecogeographical features(substrate,habitat,distribution),and a keytable allowing the identification of all accepted taxa is provided.The new species are:Cora accipiter Moncada,Madrin˜a´n&Lücking spec.nov.,C.applanata Moncada,Soto-Medina&Lücking spec.nov.,C.arachnodavidea Moncada,Dal Forno&Lücking spec.nov.,C.arborescens Dal Forno,Chaves&Lücking spec.nov.,C.arcabucana Moncada,C.Rodrı´guez&Lücking spec.nov.,C.aturucoa Lücking,Moncada&C.Vargas spec.nov.,C.auriculeslia Moncada,Ya´nez-Ayabaca&Lücking spec.nov.,C.barbifera Moncada,Patin˜o&Lücking spec.nov.,C.boleslia Lücking,E.Morales&Dal Forno spec.nov.,C.caliginosa Holgado,Rivas Plata&Perlmutter spec.nov.,C.campestris Dal Forno,Eliasaro&Spielmann spec.nov.,C.canari Nugra,Dal Forno&Lücking spec.nov.,C.caraana Lücking,Martins&Lucheta spec.nov.,C.casasolana Moncada,R.-E.Pe´rez&Lücking spec.nov.,C.caucensis Moncada,M.Gut.&Lücking spec.nov.,C.celestinoa Moncada,CabreraAmaya&Lücking spec.nov.,C.comaltepeca Moncada,R.-E.Pe´rez&Herrera-Camp.spec.nov.,C.corani Lücking,E.Morales&Dal Forno spec.nov.,C.corelleslia Moncada,A.Sua´rez-Corredor&Lücking spec.nov.,C.crispoleslia Moncada,J.Molina&Lücking spec.nov.,C.cuzcoensis Holgado,Rivas Plata&Perlmutter spec.nov.,C.dalehana Moncada,Madrin˜a´n&Lücking spec.nov.,C.davibogotana Lücking,Moncada&Coca spec.nov.,C.davicrinita Moncada,Madrin˜a´n&Lücking spec.nov.,C.davidia Moncada,L.Vargas&Lücking spec.nov.,C.dewisanti Moncada,A.Sua´rez-Corredor&Lücking spec.nov.,C.dulcis Moncada,R.-E.Pe´rez&Lücking spec.nov.,C.elephas Lücking,Moncada&L.Vargas spec.nov.,C.fuscodavidiana Lücking,Moncada&L.Vargas spec.nov.,C.garagoa Simijaca,Moncada&Lücking spec.nov.,C.gigantea Lücking,Moncada&Coca spec.nov.,C.gomeziana Dal Forno,Chaves&Lücking spec.nov.,C.guajalitensis Lücking,Robayo&Dal Forno spec.nov.,C.hafecesweorthensis Moncada,Lücking&R.Pela´ez spec.nov.,C.haledana Dal Forno,Chaves&Lücking spec.nov.,C.hawksworthiana Dal Forno,P.Nelson&Lücking spec.nov.,C.hochesuordensis Lücking,E.Morales&Dal Forno spec.nov.,C.hymenocarpa Lücking,Chaves&Lawrey spec.nov.,C.imi Lücking,Chaves&Lawrey spec.nov.,C.itabaiana Dal Forno,Aptroot&M.Ca´ceres spec.nov.,C.leslactuca nov.,C.maxima Wilk,Dal Forno&Lücking spec.nov.,C.minutula Lücking,Moncada&Ya´nez-Ayabaca spec.nov.,C.palaeotropica Weerakoon,Aptroot&Lücking spec.nov.,C.palustris Dal Forno,Chaves&Lücking spec.nov.,C.parabovei Dal Forno,Kukwa&Lücking spec.nov.,C.paraciferrii Lücking,Moncada&J.E.Hern.spec.nov.,C.paraminor Dal Forno,Chaves&Lücking spec.nov.,C.pastorum Moncada,Patin˜o&Lücking spec.nov.,C.pichinchensis Paredes,Jonitz&Dal Forno spec.nov.,C.pikynasa J.-M.Torres,Moncada&Lücking spec.nov.,C.pseudobovei Wilk,Dal Forno&Lücking spec.nov.,C.pseudocorani Lücking,E.Morales&Dal Forno spec.nov.,C.putumayensis L.J.Arias,Moncada&Lücking spec.nov.,C.quillacinga Moncada,F.Ortega&Lücking spec.nov.,C.rothesiorum Moncada,Madrin˜a´n&Lücking spec.nov.,C.rubrosanguinea Nugra,Moncada&Lücking spec.nov.,C.santacruzensis Dal Forno,Bungartz&Ya´nezAyabaca,spec.nov.,C.schizophylloides Moncada,C.Rodrı´guez&Lücking spec.nov.,C.smaragdina Lücking,Rivas Plata&Chaves spec.nov.,C.soredavidia Dal Forno,Marcelli&Lücking spec.nov.,C.subdavicrinita Moncada,J.Molina&Lücking spec.nov.,C.suturifera Nugra,Besal&Lücking spec.nov.,C.terrestris Dal Forno,Chaves&Lücking spec.nov.,C.terricoleslia Wilk,Dal Forno&Lücking spec.nov.,C.udebeceana Moncada,R.Pela´ez&Lücking,Moncada&R.Pela´ez spec.Lücking spec.nov.,C.urceolata Moncada,Coca&Lücking spec.nov.,C.verjonensis Lücking,Moncada&Dal Forno spec.nov.,C.viliewoa Lücking,Chaves&Soto-Medina spec.nov.,and C.yukiboa Mercado-Dı´az,Moncada&Lücking spec.nov.Furthermore,the taxonomic status of the recently described or recognized species C.arachnoidea,C.aspera,C.ciferrii,and C.reticulifera,is revised.
