Wilfredo F. Garcia-Beltran,K. S. St. Denis,Angelique Hoelzemer,Evan C. Lam,Adam Nitido,M. Sheehan,Cristhian Berríos,Onosereme Ofoman,Christina C. Chang,Blake M. Hauser,Jared Feldman,Alex Roederer,David Gregory,Mark C. Poznansky,Aaron G. Schmidt,A. John Iafrate,Vivek Naranbhai,Alejandro B. Balazs +17 more
TL;DR: In this article , the authors measured the neutralization potency of sera from 88 mRNA-1273, 111 BNT162b, and 40 Ad26.1.1/B.COV2.
Journal ArticleDOI

Vivek Naranbhai,Anusha Nathan,C. Kaseke,Cristhian Berríos,Ashok Khatri,Shawn Choi,Matthew A. Getz,Rhoda Tano-Menka,Onosereme Ofoman,Alton C. Gayton,Fernando Senjobe,Zezhou Zhao,K. S. St. Denis,Evan C. Lam,Mary Carrington,Wilfredo F. Garcia-Beltran,Alejandro B. Balazs,Bruce D. Walker,A. John Iafrate,Gaurav D. Gaiha +19 more
TL;DR: In this article , the authors show that T cell responses in individuals with prior infection, vaccination, both prior infection and vaccination, and boosted vaccination are largely preserved to Omicron spike and non-spike proteins.
Journal ArticleDOI
Electrooxidation of 2,4-dichlorophenol and other polychlorinated phenols at a glassy carbon electrode
M.S. Ureta-Zañartu,P. Bustos,Cristhian Berríos,María Cristina Diez,María de la Luz Mora,Claudio Gutiérrez +5 more
TL;DR: In this paper, a dual mechanism where one pathway yields a quinone-like species and the other one leads to insoluble polymers that passivate the electrode surface is proposed.
Journal ArticleDOI
Electrooxidation of 2-chlorophenol on polyNiTSPc-modified glassy carbon electrodes
M.S. Ureta-Zañartu,Cristhian Berríos,Jorge Pavez,José H. Zagal,Claudio Gutiérrez,José F. Marco +5 more
TL;DR: In this article, the electrooxidation of 2-chlorophenol (2-CP) on poly-nickel tetrasulfophthalocyanine (polyNiTSPc) modified glassy carbon (GC) and indium tin oxide (ITO) electrodes was studied by cyclic voltammetry and in situ UV-Vis transmission spectroscopy.
Journal ArticleDOI
Theoretical and spectroscopic study of nickel(II) porphyrin derivatives.
Cristhian Berríos,Gloria I. Cárdenas-Jirón,José F. Marco,Claudio Gutiérrez,M.S. Ureta-Zañartu +4 more
TL;DR: A set of substituted (sulfonate, amino) nickel porphyrin derivatives such as phthalocyanine and phenylporphyrin was studied by spectroscopic and quantum-chemical methods and calculated values of electronic transitions between the frontier molecular orbitals are in good agreeement with the UV-vis data.
