Evidence supporting a 1,2-dioxetanone as an intermediate in the benzofuran-2(3H)-one chemiluminescence.

Photochemical & photobiological sciences : Official journal of the European Photochemistry Association and the European Society for Photobiology

Ciscato LF, Bartoloni FH, Colavite AS, Weiss D, Beckert R, Schramm S.
PMID: 24162255
Photochem Photobiol Sci. 2014 Jan;13(1):32-7. doi: 10.1039/c3pp50345c. Epub 2013 Oct 28.

The mechanism of the chemiluminescent reaction of ethyl (5-fluoro-2-oxo-2,3-dihydrobenzofuran-3-yl) carbamate (a 2-coumaranone derivative) with a base and molecular oxygen was investigated. New evidence from the reaction kinetics and absorption/emission profiles was obtained, supporting the existence of a 1,2-dioxetanone as...

Polymer induced changes of the crystallization scenario in suspensions of hard sphere like microgel particles.

The Journal of chemical physics

PMID: 22779618
J Chem Phys. 2012 Jun 21;136(23):234906. doi: 10.1063/1.4729562.

We investigated the crystallization scenario of highly cross linked polystyrene particles dispersed in the good solvent 2-ethylnaphtalene and their mixtures with non-adsorbing low molecular weight polysterene polymer using time resolved static light scattering. The samples were prepared slightly below...

No ubiquitin anchors and fully RIGged.

Immunity. 2012 Jun 29;36(6):897-9. doi: 10.1016/j.immuni.2012.06.005.

Unanchored chains of ubiquitin have recently been proposed to play a role in signaling. In this issue of Immunity, Jiang et al. (2012) demonstrate that binding of free polyubiquitin to the viral RNA sensors RIG-I and MDA5 leads to...

Angle-dependent evolution of the Fulde-Ferrell-Larkin-Ovchinnikov state in an organic superconductor.

Physical review letters

Beyer R, Bergk B, Yasin S, Schlueter JA, Wosnitza J.
PMID: 23030197
Phys Rev Lett. 2012 Jul 13;109(2):027003. doi: 10.1103/PhysRevLett.109.027003. Epub 2012 Jul 11.

We report magnetic-field and angular-dependent high-resolution specific-heat measurements of the organic superconductor β''-(BEDT-TTF)2SF5CH2CF2SO3. When the magnetic field is aligned precisely within the conducting BEDT-TTF layer, at low temperatures a clear upturn of the upper critical field beyond the Pauli...

Trapped in imidazole: how to accumulate multiple photoelectrons on a black-absorbing ruthenium complex.

Chemistry (Weinheim an der Bergstrasse, Germany)

Zedler L, Kupfer S, de Moraes IR, Wächtler M, Beckert R, Schmitt M, Popp J, Rau S, Dietzek B.
PMID: 24616182
Chemistry. 2014 Mar 24;20(13):3793-9. doi: 10.1002/chem.201304937. Epub 2014 Feb 24.

Ruthenium dyes incorporating a 4H-imidazole chromophore as a ligand exhibit a spectrally broad absorption in the UV/Vis region. Furthermore, they show the ability to store two electrons within the 4H-imidazole ligand. These features render them promising molecular systems, for...

Evaluation of Resistance to Powdery Mildew in Triticale Seedlings and Adult Plants.

Plant disease

Troch V, Audenaert K, Vanheule A, Bekaert B, Höfte M, Haesaert G.
PMID: 30722401
Plant Dis. 2013 Mar;97(3):410-417. doi: 10.1094/PDIS-02-12-0161-RE.

Triticale (×Triticosecale) is the intergeneric hybrid between the female parent wheat and the male parent rye. With the expansion of the triticale growing area, powdery mildew emerged on this new host and has become a significant disease on triticale....

Interleukin-17 signaling triggers degradation of the constitutive NF-κB inhibitor ABIN-1.

ImmunoHorizons

Cruz JA, Childs EE, Amatya N, Garg AV, Beyaert R, Kane LP, Aneskievich BJ, Ma A, Gaffen SL.
PMID: 30761389
Immunohorizons. 2017 Sep;1(7):133-141. doi: 10.4049/immunohorizons.1700035.

IL-17 activates NF-κB and inducing expression of proinflammatory genes. IL-17 drives disease in autoimmune conditions, and anti-IL-17 antibodies have shown impressive success in the clinic. Although produced by lymphocytes, IL-17 predominantly signals in fibroblasts and epithelial cells. IL-17-driven inflammation...

The impact of continuous positive airway pressure on cardiac arrhythmias in patients with sleep apnea.

Journal of research in medical sciences : the official journal of Isfahan University of Medical Sciences

Varga PC, Rosianu HS, Vesa ŞC, Hancu BGD, Beyer R, Pop CM.
