Effects of Nuclear Spin Polarization on Reaction Dynamics in Photosynthetic Bacterial Reaction Centers
Nuclear Spin Polarization Reaction Dynamics Photosynthetic Bacterial Reaction Centers
2016/5/20
Singlet-triplet mixing in the initial radical-pair state, P[unk]I[unk], of photosynthetic bacterial reaction centers is due to the hyperfine mechanism at low magnetic fields and both the hyperfine and...
Chemically Induced Dynamic Nuclear Polarization Studies of Yeast tRNAPhe
Chemically Induced Dynamic Nuclear Polarization Studies Yeast tRNAPhe
2016/5/20
Chemically induced dynamic nuclear polarization (CIDNP) has been observed from yeast tRNAPhe following reaction with photoexcited riboflavin. At 20 OC, several resonances of tRNA in the native form sh...

Chemically Induced Dynamic Nuclear Polarization Studies Guanosine Nucleotides Dinucleotides Oligonucleotides
2016/5/20
The nuclear magnetic resonance (NMR) technique of chemically induced dynamic nuclear polarization (CIDNP) has been used to study the reactions between photoexcited flavins and a wide variety of nucleo...
UV Excimer Laser Chemically Induced Dynamic Nuclear Polarization of Amino Acids at 360 MHz
UV Excimer Laser Chemically Dynamic Nuclear Polarization Amino Acids 360 MHz
2016/5/20
A system has been developed which permits ultraviolet irradiation of samples in the probe of a 360 MHz nmr spectrometer using an excimer laser (A= 249 or 308 nm). This system is ideally suited for stu...
Laser Chemically Induced Dynamic Nuclear Polarization Study of the Reaction between Photoexcited Flavins and Tryptophan Derivatives at 360 MHz
Laser Chemically Induced Dynamic Nuclear Polarization Study Photoexcited Flavins Tryptophan Derivatives 360 MHz
2016/5/20
Chemically induced dynamic nuclear polarization (CIDNP) is generated when tryptophan (Trp), its derivatives,or Trp-containing peptides react with photoexcited flavins in a 360-MHz NMR spectrometer. In...
Synthetic spatially graded Rac activation drives directed cell polarization and locomotion
Synthetic spatially graded Rac directed cell polarization and locomotion Molecular Networks
2012/5/2
Migrating cells possess intracellular gradients of Rho GTPases, but it is unknown whether these shallow gradients themselves can induce motility. Here we describe a new method to present cells with in...
Polarization Sensitive Optical Coherence Tomography for Blood Glucose Monitoring in Human Subjects
Circularly polarized light chiral glucose scattering coefficient tissue phantom human subjects
2012/2/28
A device based on Polarization sensitive optical coherence tomography is developed to monitor blood glucose levels in human subjects. The device was initially tested with tissue phantom. The measureme...
Asymptotic and bifurcation analysis of wave-pinning in a reaction-diffusion model for cell polarization
Asymptotic bifurcation analysis wave-pinning reaction-diffusion model
2011/1/5
We describe and analyze a bistable reaction-diffusion (RD) model for two interconverting chemical species that exhibits a phenomenon of wave-pinning: a wave of activation of one of the species is init...
