Development of in-airway laser absorption spectroscopy for respiratory based measurements of cardiac output

open access: yesScientific Reports, 2021
Respiratory approaches to determining cardiac output in humans are securely rooted in mass balance and therefore potentially highly accurate. To address existing limitations in the gas analysis, we developed an in-airway analyser based on laser ...

Nuclear export of the pre-60S ribosomal subunit through single nuclear pores observed in real time

open access: yesNature Communications, 2021
Ribosomal biogenesis is known to require nuclear to cytoplasmic export, but the precise kinetics remain unclear. Here, the authors use super-resolution confocal microscopy and single molecule tracking to visualize export of single pre-60S particles ...

Amplification of weak magnetic field effects on oscillating reactions

open access: yesScientific Reports, 2021
We explore the possibility that chemical feedback and autocatalysis in oscillating chemical reactions could amplify weak magnetic field effects on the rate constant of one of the constituent reactions, assumed to proceed via a radical pair mechanism ...

Bacterial F-type ATP synthases follow a well-choreographed assembly pathway

open access: yesNature Communications, 2022
ATPases are the macromolecular machines for cellular energy production. Here the authors investigate factors that govern the assembly of the F1 complex from a bacterial F-type ATPase and relate differences in activity of complexes assembled in cells and ...

Exact electronic states with shallow quantum circuits from global optimisation

open access: yesnpj Quantum Information, 2023
Quantum computers promise to revolutionise molecular electronic simulations by overcoming the exponential memory scaling. While electronic wave functions can be represented using a product of fermionic unitary operators, the best ansatz for strongly ...

The LBFGS Quasi-Newtonian Method for Molecular Modeling Prion AGAAAAGA Amyloid Fibrils [PDF]

open access: yes, 2012
Experimental X-ray crystallography, NMR (Nuclear Magnetic Resonance) spectroscopy, dual polarization interferometry, etc are indeed very powerful tools to determine the 3-Dimensional structure of a protein (including the membrane protein); theoretical ...

Modular detergents tailor the purification and structural analysis of membrane proteins including G-protein coupled receptors

open access: yesNature Communications, 2020
Detergents are indispensable reagents in membrane protein structural biology. Here, L. H. Urner and co-workers introduce oligoglycerol detergents (OGDs) and use native mass spectrometry to show how interactions of membrane proteins with native membrane ...
