G-Quadruplexes
Guanine (G)-rich sequences in nucleic acids can assemble into G-quadruplex structures that involve G-quartets linked by loop nucleotides. The structural and topological diversity of G-quadruplexes have attracted great attention...

Coherent anti-Stokes Raman spectroscopy of single and multi-layer graphene.
Spontaneous Raman spectroscopy is a powerful characterization tool for graphene research. Its extension to the coherent regime, despite the large nonlinear third-order susceptibility of graphene, has so far proven challenging....

Remote stereocontrol in [3,3]-sigmatropic rearrangements
The Ireland - Claisen [3,3]-sigmatropic rearrangement has been used to access biologically important β,β′-dihydroxy α-amino acids. The rearrangement reported is highly stereoselective and offers excellent levels of remote...

RNA promotes phase separation of glycolysis enzymes into yeast G bodies in hypoxia.
In hypoxic stress conditions, glycolysis enzymes assemble into singular cytoplasmic granules called glycolytic (G) bodies. G body formation in yeast correlates with increased glucose consumption and cell survival. However, the...

Modelling and simulation of biased agonism dynamics at a G protein-coupled receptor.
Theoretical models of G protein-coupled receptor (GPCR) concentration-response relationships often assume an agonist producing a single functional response via a single active state of the receptor. These models have largely...

Raman spectroscopy of graphene under ultrafast laser excitation.
The equilibrium optical phonons of graphene are well characterized in terms of anharmonicity and electron-phonon interactions; however, their non-equilibrium properties in the presence of hot charge carriers are still not fully...

Amino-Acid-Derived Naphthalenediimides as Versatile G-Quadruplex Binders

The design and synthesis of water soluble, amino-acid-functionalised naphthalenediimides (NDIs) as potential ligands of native G-quadruplexes is reported. The NDIs were tested on a panel of oncogene promoters, on the human...

Structural basis of G-quadruplex unfolding by the DEAH/RHA helicase DHX36.
Guanine-rich nucleic acid sequences challenge the replication, transcription, and translation machinery by spontaneously folding into G-quadruplexes, the unfolding of which requires forces greater than most polymerases can...

G-quadruplexes in pathogens
DNA can form several secondary structures besides the classic double helix: one that has received much attention in recent years is the G-quadruplex (G4). This is a stable four-stranded structure formed by the stacking of...

Anisotropy versus circular dichroism in second harmonic generation from fourfold symmetric arrays of G-shaped nanostructures

Circular dichroism in optical second harmonic generation (CD-SHG) is studied in planar symmetrical arrays of G-shaped and mirror-G-shaped nanostructures. Anisotropic CD-SHG measurements demonstrate a strong dependence of the...
