5Controlled acceleration of GeV electron beams in an all-optical plasma waveguide显示文摘Laser-plasma accelerators(LPAs)produce electric fields of the order of 100 GV m-1,more than 1000 times larger than those produced by radio-frequency accelerators.These uniquely strong fields make LPAs a promising path to generate electron beams beyond the TeV,an important goal in high-energy physics.Yet,large electric fields are of little benefit if they are not maintained over a long distance.It is therefore of the utmost importance to guide the ultra-intense laser pulse that drives the accelerator.Reaching very high energies is equally useless if the properties of the electron beam change completely from shot to shot,due to the intrinsic lack of stability of the injection process.State-of-the-art laser-plasma accelerators can already address guiding and control challenges separately by tweaking the plasma structures.However,the production of beams that are simultaneously high quality and high energy has yet to be demonstrated.This paper presents a novel experiment,coupling laser-plasma waveguides and controlled injection techniques,facilitating the reliable and efficient acceleration of high-quality electron beams up to 1.1 GeV,from a 50 TW-class laser.Kosta Oubrerie Adrien Leblanc Olena Kononenko Ronan Lahaye Igor A.Andriyash Julien Gautier Jean-Philippe Goddet Lorenzo Martelli Amar TafziKim Ta Phuoc Slava Smartsev Cédric Thaury 2022Light(Science & Applications)2022,11,7:1
6α2-Heremans-schmid glycoprotein(fetuin A)downregulation and its utility in inflammatory bowel disease显示文摘AIM To investigate the impact of inflammatory bowel disease (IBD) on α2-Heremans-Schmid Glycoprotein(AHSG/fetuin A) and potential associations with disease and patient characteristics.METHODS AHSG serum levels were determined in treatment-na?ve newly-diagnosed patients, 96 with ulcerative colitis(UC), 84 with Crohn's disease (CD), 62 with diarrheapredominant or mixed irritable bowel syndrome (IBS, D- and M- types) and 180 healthy controls (HC), by an enzyme linked immunosorbent assay (ELISA).All patients were followed for a minimum period of 3 years at the Gastroenterology Department of the University Hospital of Larissa, Greece. C-reactive protein(CRP), anti-glycan antibodies, anti-Saccharomyces cerevisiae mannan antibodies Ig G, anti-mannobioside carbohydrate antibodies Ig G, anti-laminariobioside carbohydrate antibodies Ig G and anti-chitobioside carbohydrate antibodies Ig A were also determined via immunonephelometry and ELISA, respectively.RESULTS The mean ± SE of serum AHSG, following adjustment for confounders, was 0.32 ± 0.02 g/L in IBD, 0.32 ± 0.03 g/L in CD and 0.34 ± 0.03 g/L in UC patients, significantly lower than in IBS patients(0.7 ± 0.018 g/L) and HC (0.71 ± 0.02 g/L) (P < 0.0001, in all cases). AHSG levels were comparable between the CD and UC groups. Based on AHSG levels IBD patients could be distinguished from HC with about 90% sensitivity and specificity. Further adjusted analysis verified the inverse association between AHSG and penetrating, as well as stricturing CD (partial correlation coefficient: -0.45 and -0.33, respectively) (P < 0.05). After adjusting for confounding factors, inverse correlations between AHSG and CRP and the need for anti-TNFα therapy or surgery, were found (partial correlation coefficients:-0.31,-0.33,-0.41, respectively, P < 0.05, in all cases). Finally, IBD individuals who were seropositive, for at least one marker, had AHSG levels falling within the two lower quartiles (OR = 2.86, 95%CI: 1.5-5.44, P < 0.001) while those with at least two serological markers positive exhibited AHSG concentrations within the lowest quartile (OR = 5.03, 95%CI: 2.07-12.21, P < 0.001), after adjusting for age, sex and smoking.CONCLUSION AHSG can be used to distinguish between IBD and IBS patients or HC while at the same time 'predicting' complicated disease behavior, need for therapy escalation and surgery. Moreover, AHSG may offer new insights into the pathogenesis of IBD, since it is involved in key processes.Anastassios C Manolakis Gregory Christodoulidis Andreas N Kapsoritakis Panagiotis Georgoulias Elisavet K Tiaka Kostas Oikonomou Varvara J Spyros P Potamianos 2017World Journal of Gastroenterology2017,23,3:1
