2Measurements of dihadron correlations relative to the event plane in Au+Au collisions at√^(S)NN=200 GeV显示文摘Dihadron azimuthal correlations containing a high transverse momentum(pr)trigger particle are sensit-ive to the properties of the nuclear medium created at RHIC through the strong interactions occurring between the traversing parton and the medium,ie.jet-quenching.Previous measurements revealed a strong modification to di-hadron azimuthal correlations in Au+Au collisions with respect to ptp and d+Au collisions.The modification in-creases with the collision centrality,suggesting a path-length or energy density dependence to the je-quenching ef-fect.This paper reports STAR measurements of dihadron azimuthal correlations in mid-central(20%-60%)Au+Au collisions at√^(S)NN=200 GeV as a function of the trigger particle's azimuthal angle relative to the event plane,Ф_(s)=|Ф_(t)-ψ_(Ep)|.The azimuthal correlation is studied as a function of both the trigger and associated particle pr.The subtractions of the combinatorial background and anisotropic flow,assuming Zero Yield At Minimum(ZYAM),are described.The correlation results are first discussed with subtraction of the even harmonic(elliptic and quadrangu-lar)flow backgrounds.The away-side correlation is strongly modifed,and the modification varies withФ_(s),with a double-peak structure for out-of-plane trigger particles.The near-side ridge(long range pseudo-rapidity△_(η)correla-tion)appears to drop with increasingФ_(s)while the jet-like component remains approximately constant.The correla-tion functions are further studied with the subtraction of odd harmonic triangular flow background arising from fluc-tuations.It is found that the triangular flow,while responsible for the majority of the amplitudes,is not sufficient to explain theφs-dependence of the ridge or the away-side double-peak structure.The dropping ridge withФ_(s)could be attributed to aФ_(s)-dependent lliptie anisotropy;however,the physics mechanism of the ridge remains an open ques-tion.Even with aФ_(s)-dependent elliptic flow,the away-side correlation structure is robust.These results,with extens-ive systematic studies of the dihadron correlations as a function ofФ_(s),trigger and associated particle pT,and the pseudo-rapidity range△_(η),should provide stringent inputs to help understand the underlying physics mechanisms of jet-medium interactions in high energy nuclear collisions.H.Agakishiev M.M.Aggarwal Z.Ahammed A.V.Alakhverdyants I.Alekseev J.Alford B.D.Anderson C.D.Anson D.Arkhipkin G.S.Averichev J.Balewski

3TiO_(2) Nanocrystals Grown on Graphene as Advanced Photocatalytic Hybrid Materials显示文摘A graphene/TiO_(2) nanocrystals hybrid has been successfully prepared by directly growing TiO_(2) nanocrystals on graphene oxide(GO)sheets.The direct growth of the nanocrystals on GO sheets was achieved by a two-step method,in which TiO_(2) was first coated on GO sheets by hydrolysis and crystallized into anatase nanocrystals by hydrothermal treatment in the second step.Slow hydrolysis induced by the use of EtOH/H2O mixed solvent and addition of H2SO4 facilitates the selective growth of TiO_(2) on GO and suppresses growth of free TiO_(2) in solution.The method offers easy access to the GO/TiO_(2) nanocrystals hybrid with a uniform coating and strong interactions between TiO_(2) and the underlying GO sheets.The strong coupling gives advanced hybrid materials with various applications including photocatalysis.The prepared graphene/TiO_(2) nanocrystals hybrid has superior photocatalytic activity to other TiO_(2) materials in the degradation of rhodamine B,showing an impressive three-fold photocatalytic enhancement over P25.It is expected that the hybrid material could also be promising for various other applications including lithium ion batteries,where strong electrical coupling to TiO_(2) nanoparticles is essential.Yongye Liang Hailiang Wang Hernan Sanchez Casalongue Zhuo Chen Hongjie Dai 2010Nano Research2010,3,10:57
4The role of gut microbiota(commensal bacteria)and the mucosal barrier in the pathogenesis of inflammatory and autoimmune diseases and cancer:contribution of germ-free and gnotobiotic animal models of human diseases显示文摘Metagenomic approaches are currently being used to decipher the genome of the microbiota(microbiome),and,in parallel,functional studies are being performed to analyze the effects of the microbiota on the host.Gnotobiological methods are an indispensable tool for studying the consequences of bacterial colonization.Animals used as models of human diseases can be maintained in sterile conditions(isolators used for germ-free rearing)and specifically colonized with defined microbes(including non-cultivable commensal bacteria).The effects of the germ-free state or the effects of colonization on disease initiation and maintenance can be observed in these models.Using this approach we demonstrated direct involvement of components of the microbiota in chronic intestinal inflammation and development of colonic neoplasia(i.e.,using models of human inflammatory bowel disease and colorectal carcinoma).In contrast,a protective effect of microbiota colonization was demonstrated for the development of autoimmune diabetes in non-obese diabetic(NOD)mice.Interestingly,the development of atherosclerosis in germ-free apolipoprotein E(ApoE)-deficient mice fed by a standard low-cholesterol diet is accelerated compared with conventionally reared animals.Mucosal induction of tolerance to allergen Bet v1 was not influenced by the presence or absence of microbiota.Identification of components of the microbiota and elucidation of the molecular mechanisms of their action in inducing pathological changes or exerting beneficial,disease-protective activities could aid in our ability to influence the composition of the microbiota and to find bacterial strains and components(e.g.,probiotics and prebiotics)whose administration may aid in disease prevention and treatment.Helena Tlaskalova-Hogenova Renata Stepankova Hana Kozakova Tomas Hudcovic Luca Vannucci Ludmila Tuckova Pavel Rossmann TomasHrncır Miloslav Kverka Zuzana Zakostelska Klara Klimesova Jaroslava Pribylova Jirina Bartova Daniel Sanchez Petra Fundova Dana Borovska Dagmar Sru˚tkova Zdenek Zıdek Martin Schwarzer Pavel Drastich David P Funda 2011Cellular & Molecular Immunology2011,8,2:47

8The Genome of Cucurbita argyrosperma (Silver- Seed Gourd) Reveals Faster Rates of Protein- Coding Gene and Long Noncoding RNA Turnover and Neofunctionalization within Cucurbita显示文摘Whole-genome duplications are an important source of evolutionary novelties that change the mode and tempo at which genetic elements evolve within a genome. The Cucurbita genus experienced a wholegenome duplication around 30 million years ago, although the evolutionary dynamics of the coding and noncoding genes in this genus have not yet been scrutinized. Here, we analyzed the genomes of four Cucurbita species, in eluding a newly assembled genome of Cucurbita argyrosperma, and compared the gene con tents of these species with those of five other members of the Cucurbitaceae family to assess the evolutionary dynamics of protein-coding and long intergenic noncoding RNA (lincRNA) genes after the genome duplication. We report that Cucurbita genomes have a higher protein-coding gene birth-death rate compared with the genomes of the other members of the Cucurbitaceae family. C. argyrosperma gene families associated with pollination and transmembrane transport had significantly faster evolutionary rates. lincRNA families showed high levels of gene turnover throughout the phylogeny, and 67.7% of the lincRNA families in Cucurbita showed evidence of birth from the neofunctionalization of previously existing protein-coding genes. Collectively, our results suggest that the whole-genome duplication in Cucurbita resulted in faster rates of gene family evolution through the neofunctionalization of duplicated genes.Josue Barrera-Red on do Enrique Ibarra-Laclette Alejandra Vazquez-Lobo Yocelyn T.

9IL-10 and TNF-α promoter haplotypes are associated with childhood Crohn’s disease location显示文摘AIM: To determine the distribution and frequencies of the genotypes and haplotypes of the genes encoding for the glucocorticoid receptor (GR), the tumor necrosis factor (TNF)-α and the interleukin (IL)-10 in childhood Crohn’s disease (CD) and to assess the impact of the corresponding DNA variants on clinical and disease phenotypes. METHODS: Ten variants in GR, TNF-α and IL-10 were genotyped in 113 childhood CD cases and 95 healthy subjects, both of French-Canadian origin. RESULTS: For the GR polymorphisms (R23K and N363S) and IL-10 variants in the 5’flanking region (-1082 G > A, -819 T > C and -592 A > C), no difference was observed in allele and genotype frequencies between CD patients and controls. At the haplotype level, we found three IL-10 haplotypes previously described in Caucasians (GCC, ACC and ATA) and three novel haplotypes only present in IBD patients. When we analyzed the haplotype distribution with the anatomical location of the disease, the GCC haplotype was associated with the colonic and the ACC haplotype with the terminal ileum location, respectively. The genotyping of fi ve polymorphisms in the promoter region of the TNF-α gene (-1031 T > C, -863 A > C, -857 T > C, -308 A > G and -238 A > G) revealed a significant overrepresentation of homozygous -1031 CC among CD patients (OR = 9.9) and an association with the colonic location. For TNF-α, eleven haplotypes were inferred, including two frequent ones, TCCGG and CACGG, which were significantly observed more frequently in controls and cases, respectively.CONCLUSION: This is one of the fi rst studies investigating the association between haplotype structure and disease location in a CD pediatric cohort. Our results will help to increase our understanding of the genetic determinants of childhood CD.Rocio Sanchez Emile Levy Florin Costea Daniel Sinnett 2009World Journal of Gastroenterology2009,15,30:9
10Parenchymal-sparing liver surgery in patients with colorectal carcinoma liver metastases显示文摘Liver resection is the treatment of choice for patients with colorectal liver metastases(CLM).However,major resections are often required to achieve R0 resection,which are associated with substantial rates of morbidity and mortality.Maximizing the amount of residual liver gained increasing significance in modern liver surgery due to the high incidence of chemotherapyassociated parenchymal injury.This fact,along with the progressive expansion of resectability criteria,has led to the development of a surgical philosophy known as 'parenchymal-sparing liver surgery'(PSLS).This philosophy includes a variety of resection strategies,either performed alone or in combination with ablative therapies.A profound knowledge of liver anatomy and expert intraoperative ultrasound skills are required to perform PSLS appropriately and safely.There is a clear trend toward PSLS in hepatobiliary centers worldwide as current evidence indicates that tumor biology is the most important predictor of intrahepatic recurrence and survival,rather than the extent of a negative resection margin.Tumor removal avoiding the unnecessary sacrifice of functional parenchyma has been associated with less surgical stress,fewer postoperative complications,uncompromised cancer-related outcomes and higher feasibility of future resections.The increasing evidence supporting PSLS prompts its consideration as the gold-standard surgical approach for CLM.Fernando A Alvarez Rodrigo Sanchez Claria Sebastian Oggero Eduardo de Santibanes 2016World Journal of Gastrointestinal Surgery2016,8,6:8

13胸腰段脊柱骨折定量影像学显示文摘描述影响胸腰段脊柱不同类型骨折,以及指导脊柱骨折治疗的不同分类及关键影响因素。目前脊柱骨折分类以Denis三柱模型为基石,包括压缩性骨折、爆裂性骨折、屈曲牵张骨折和骨折伴脱位。骨折分类系统包括胸腰椎损伤分类和严重程度评分(Thoracolumbar Injury Classification and Severity Score,TLICS)系统和AO脊柱胸腰椎损伤分类和严重程度评分(AOSpine-TLICS)。正确分类需要定量成像方法,采用多个测量指标来评定其属于不同TLICS或AOSpine-TLICS类型。如果TLICS评分>4或者AOSpine-TLICS评分>5,则患者需要手术治疗。本文重点描述X线片、CT及MRI影像表现和测量参数,包括爆裂性骨折患者中椎体楔形变成角和压缩性骨折椎体高度丢失百分比、椎弓根间距和腰椎管狭窄程度以及一些严重骨折(如屈曲牵张骨折、骨折伴脱位)患者的椎体位移和棘突间距增加。通过图解和影像案例展现这些影像学特征和相关参数。Fernando Ruiz Santiago Pablo Tomas Munoz Elena Moya Sanchez Marta Revelles Paniza Alberto Martinez Martinez Antonio Luis Perez Abela 2017临床与病理杂志2017,37,4:7
14Growth performance,gastrointestinal weight,microbial metabolites and apparent retention of components in broiler chickens fed up to 11%rice bran in a corn-soybean meal diet without or with a multi-enzyme supplement显示文摘We investigated the effects of adding up to 11% rice bran(RB) in corn-soybean meal diets fed to broiler chickens without or with a multi-enzyme supplement(MES). The MES supplied xylanase, b-glucanase invertase, protease, cellulase, a-amylase and mannanase with targeted activity of 2,500, 300, 700, 10,0001,200, 24,000, and 20 U/kg of feed, respectively. The study used a two-phase feeding program(starter d 0 to 24; finisher, d 25 to 35) with RB added at 5% and 11%, respectively creating 4 diets in each phase Diets were iso-caloric and iso-nitrogenous and contained phytase(500 FTU/kg) and TiO_2 as a digestibility marker. Three hundred and sixty d-old male Ross 708 broiler chicks were placed in cages based on BW(15 birds/cage) and allocated to 4 diets(n = 6). Birds had free access to feed and water. Body weight and feed intake were recorded. Excreta samples were collected 3 d prior to the end of each phase for apparent retention(AR) of components. Samples of birds were sacrificed on d 24 and 35 for gut weight and ceca digesta for organic acid content. There was no interaction(P > 0.10) between RB and MES on BWG and FCR in starter or finisher phase. In finisher phase, birds fed MES had better BWG(961 versus 858 g) and FCR(1.69 versus 1.86) than birds fed non-MES diets(P < 0.01). Feeding RB reduced(P = 0.02) BWG in finisher phase resulting in lower d 35 BW. Birds fed RB had higher(P 0.01) gizzard weight on d 24 and 35 than non-RB birds. An interaction(P 0.01) between RB and MES on concentrations of propionic and iso-butyric acids in ceca digesta showed that MES reduced these acids in non-RB diet. The AR of gross energy was higher(P < 0.02) for MES versus non-MES birds in starter and finisher phases. In conclusion independently, RB increased gizzard weight and reduced final BW whereas MES improved growth and energy utilization.Juan Sanchez Aizwarya Thanabalan Tanka Khanal Rob Patterson Bogdan A.Slominski Elijah Kiarie 2019Animal Nutrition2019,,1:6
15Reactive oxygen species and antioxidant properties from mushrooms显示文摘Preventive medicine and food industry have shown an increased interest in the development of natural antioxidants,since those most commonly used synthetic antioxidants may have restricted use in food.This could explain why there is currently much research on the antioxidant properties from natural products such as mushrooms.Many mushrooms have been reported to possess antioxidant properties,which enable them to neutralize free radicals.The oxygen molecule is a free radical,which lead to the generation of the reactive oxygen species and can damage the cells.Cell damage caused by free radicals appears to be a major contributor to aging and degenerative diseases.Mushrooms antioxidant components are found in fruit bodies,mycelium and culture both,which include polysaccharides,tocopherols,phenolics,carotenoids,ergosterol and ascorbic acid among others.Fruit bodies or mycelium can be manipulated to produce active compounds in a relatively short period of time,which represent a significant advantage in antioxidant compounds extraction from mushrooms.Antioxidant compounds may be extracted to be used as functional additives or mushrooms can be incorporated into our food regime,representing an alternative source of food to prevent damage caused by oxidation in the human body.Carmen Sanchez 2017Synthetic and Systems Biotechnology2017,2,1:6

17新型分子靶向药物联合放疗在肺癌中的应用显示文摘非小细胞肺癌(non-small cell lung cancer,NSCLC)约占肺癌总病例数的80%-85%,对于Ⅲ期患者来说,NSCLC约占肺癌总病例数的40%。不可切除Ⅲ期NSCLC的治疗为以铂类为基础的化疗联合胸部放疗。本文将综述正在研发中且有可能用于联合治疗的新型靶向制剂。其中最具前景的策略之一为表皮生长因子受体(epidermal growth factor receptor,EGFR)通路的抑制。放疗可激活EGFR信号,通过诱导细胞增殖并增强DNA修复而导致放疗抵抗。几项临床前模型研究表明西妥昔单抗与放疗联合具有协同效应。几项Ⅱ期试验评估了西妥昔单抗与放疗同步使用的安全性与疗效,结果喜人。吉非替尼对多种细胞系具有放疗增敏作用,其与放疗的联合已被试验用于不可切除Ⅲ期NSCLC的治疗。然而,放化疗后使用吉非替尼作为维持治疗的结果不容乐观。一项Ⅰ期试验评估了厄洛替尼与放化疗联合的疗效。放疗可通过损伤细胞膜、DNA以及微血管内皮细胞而诱导肿瘤死亡,而这反过来可增加促血管生成生长因子的产生。抗血管生长制剂可降低血管密度,但可改善肿瘤的含氧量。应用血管内皮生长因子受体(vascular endothelial growth factor receptor,VEGFR)抑制剂可通过阻断亚致死量辐射损伤的修复而增强放疗对人NSCLC的疗效。厄洛替尼、贝伐珠单抗与胸部放疗联合试验正在进行中。该三种药物联合治疗的新策略尚需制订。由于放疗可增强HSP90分子伴侣的功能从而引起肺癌细胞的放疗抵抗,此通路的阻断剂可通过抑制HIF-1a和VEGF的表达进而抑制肺癌细胞的生存和血管生成,因而可能用于减少放疗抵抗。在NSCLC和间皮瘤的临床前模型中,Aurora激酶抑制剂似乎对放疗具有增效作用。Mariano PROVENCIO Antonio SANCHEZ Pilar GARRIDO Francisco VALCARCEL 丁燕 李军 2010中国肺癌杂志2010,,8:6

19Incretins and selective renal sodium-glucose co-transporter 2 inhibitors in hypertension and coronary heart disease显示文摘Hyperglycemia is associated with an increased risk of cardiovascular disease,and the consequences ofintensive therapy may depend on the mechanism of the anti-diabetic agent(s)used to achieve a tight control.In animal models,stable analogues of glucagon-like peptide-1(GLP-1)were able to reduce body weight and blood pressure and also had favorable effects on ischemia following coronary reperfusion.In a similar way,dipeptidyl peptidase IV(DPPIV)showed to have favorable effects in animal models of ischemia/reperfusion.This could be due to the fact that DPPIV inhibitors were able to prevent the breakdown of GLP-1 and glucose-dependent insulinotropic polypeptide,but they also decreased the degradation of several vasoactive peptides.Preclinical data for GLP-1,its derivatives and inhibitors of the DPPIV enzyme degradation suggests that these agents may be able to,besides controlling glycaemia,induce cardio-protective and vasodilator effects.Notwithstanding the many favorable cardiovascular effects of GLP-1/incretins reported in different studies,many questions remain unanswered due the limited number of studies in human beings that aim to examine the effects of GLP-1 on cardiovascular endpoints.For this reason,long-term trials searching for positive cardiovascular effects are now in process,such as the CAROLINA and CARMELINA trials,which are supported by small pilot studies performed in humans(and many more animal studies)with incretin-based therapies.On the other hand,selective renal sodium-glucose co-transporter 2 inhibitors were also evaluated in the prevention of cardiovascular outcomes in type 2 diabetes.However,it is quite early to draw conclusions,since data on cardiovascular outcomes and cardiovascular death are limited and long-term studies are still ongoing.In this review,we will analyze the mechanisms underlying the cardiovascular effects of incretins and,at the same time,we will present a critical position about the real value of these compounds in the cardiovascular system and its protection.Ramiro A Sanchez Hugo Sanabria Cecilia de los Santos Agustin J Ramirez 2015World Journal of Diabetes2015,6,11:5
20Quasispecies dynamics in main core epitopes of hepatitis B virus by ultra-deep-pyrosequencing显示文摘AIM:To investigate the variability of the main immunodominant motifs of hepatitis B virus(HBV) core gene by ultra-deep-pyrosequencing(UDPS).METHODS:Four samples(2 genotype A and 2 genotype D) from 4 treatment-na ve patients were assessed for baseline variability.Two additional samples from one patient(patient 4,genotype D) were selected for analysis:one sample corresponded to a 36-mo treatment-free period from baseline and the other to the time of viral breakthrough after 18 mo of lamivudine treatment.The HBV region analyzed covered amino acids 40 to 95 of the core gene,and included the two main epitopic regions,Th50-69 and B74-84.UDPS was carried out in the Genome Sequencer FLX system(454 Life Sciences,Roche).After computer filtering of UDPS data based on a Poisson statistical model,122 813 sequences were analyzed.The most conserved position detected by UDPS was analyzed by site-directed mutagenesis and evaluated in cell culture.RESULTS:Positions with highest variability rates were mainly located in the main core epitopes,confirming their role as immune-stimulating regions.In addition,the distribution of variability showed a relationship with HBV genotype.Patient 1(genotype A) presented the lowest variability rates and patient 2(genotype A) had 3 codons with variability higher than 1%.Patient 3 and 4(both genotype D) presented 5 and 8 codons with variability higher than 1%,respectively.The median baseline frequencies showed that genotype A samples had higher variability in epitopic positions than in the other positions analyzed,approaching significance(P = 0.07,sample 1 and P = 0.05,sample 2).In contrast,there were no significant differences in variability between the epitopic and other positions in genotype D cases.Interestingly,patient 1 presented a completely mutated motif from amino acid 64 to 67(E 64 LMT 67),which is commonly recognized by T helper cells.Additionally,the variability observed in all 4 patients was particularly associated with the E 64 LMT 67 motif.Codons 78 and 79 were highly conserved in all samples,in keeping with their involvement in the interaction between the HBV virion capsid and the surface antigens(HBsAg).Of note,codon 76 was even more conserved than codons 78 and 79,suggesting a possible role in HBsAg interactions or even in hepatitis B e antigen conformation.Sequential analysis of samples from patient 4(genotype D) illustrated the dynamism of the HBV quasispecies,with strong selection of one minor baseline variant coinciding with a decrease in core variability during the treatment-free and lamivudinetreated period.The drop in variability seemed to result from a 'steady state' situation of the HBV quasispecies after selection of the variant with greatest fitness.CONCLUSION:Host immune pressure seems to be the main cause of HBV core evolution.UDPS analysis is a useful technique for studying viral quasispecies.Maria Homs Maria Buti David Tabernero Josep Quer Alex Sanchez Noelia Corral Rafael Esteban Francisco Rodriguez-Frias 2012World Journal of Gastroenterology2012,18,42:5
