Structural analysis of uniformly (13)C-labelled solids from selective angle measurements at rotational resonance

open access: yes, 2009
We demonstrate that individual H-C-C-H torsional angles in uniformly labelled organic solids can be estimated by selective excitation of (13)C double-quantum coherences under magic-angle spinning at rotational resonance. By adapting a straightforward one-

Photochemistry and internal eliminations of organosulfur and organoselenium compounds [PDF]

open access: yes, 2005
This dissertation focuses on two specific aspects of the chemistry of organosulfur and organoselnium compounds. The first is the internal elimination of the sulfinate esters, sulfonic esters, and the effects of silyl-substitution on the internal ...

Reactions of bridging vinyliminium ligands in diiron complexes

open access: yes, 2005
Bridging vinyliminium diiron complexes 1, easily accessible by insertion of alkynes (HCCR’) into the metal-carbon bond of diiron mu-aminocarbynes1, exhibit a remarkable reactivity, that allows the preparation of a variety of highly functionalised mu ...

Horizontal gene transfer of "prototype" Nramp in bacteria

open access: yes, 2003
Eukaryotic Nramp genes encode divalent metal ion permeases important for nutrition and resistance to microbial infection. Bacterial homologs encode proton-dependent transporters of manganese (MntH), and other divalent metal ions.

Involvement of the TCR Cβ FG Loop in Thymic Selection and T Cell Function

open access: yes, 2019
The asymmetric disposition of T cell receptor (TCR) Cbeta and Calpha ectodomains creates a cavity with a side-wall formed by the rigid Cbeta FG loop. To investigate the significance of this conserved structure, we generated loop deletion (betaDeltaFG ...
