New Developments in Spin Labels for Pulsed Dipolar EPR
Spin labelling is a chemical technique that enables the integration of a molecule containing an unpaired electron into another framework for study. Given the need to understand the structure, dynamics, and conformational changes of biomacromolecules ...

We present a numerical investigation on the detection of superparamagnetic labels using a giant magnetoresistance (GMR) vortex structure. For this purpose, the Landau–Lifshitz–Gilbert equation was solved numerically applying an external z-field for the ...

and P-700 (Heathcote & Evans, 1981). The existence of a group of electron acceptors with a range of redox potentials which can be sequentially reduced by the appropriate lowtemperature illumination regimens suggests that these components form an electron-transport chain t o transfer electrons from the excited-state P-700 t o ferredoxin, allowing rapid ...

SPIN-LABELED TRANSFER RNA [PDF]
The α-amino group of valyl-tRNA has been combined chemically with a nitroxide spin label through an amide linkage. This spin-labeled aminoacyl-tRNA has an electron paramagnetic resonance spectrum which reflects the mobility of the aminoacyl end of the tRNA molecule.

Broadband transmission EPR spectroscopy. [PDF]
EPR spectroscopy employs a resonator operating at a single microwave frequency and phase-sensitive detection using modulation of the magnetic field. The X-band spectrometer is the general standard with a frequency in the 9-10 GHz range.

Diosmin and Bromelain Stimulate Glutathione and Total Thiols Production in Red Blood Cells
Diosmin and bromelain are bioactive compounds of plant origin with proven beneficial effects on the human cardiovascular system. We found that diosmin and bromelain slightly reduced total carbonyls levels and had no effect on TBARS levels, as well as ...
