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...
Nuclear Magnetic Resonance of Photoexcited Triplet States. I. The Measurement of the Rate of Degenerate Singlet-Triplet Exchange for Anthracene in Solution
Nuclear Magnetic Resonance Photoexcited Triplet States Measurement Degenerate Singlet-Triplet Exchange for Anthracene
2016/5/20
The N M R spectroscopy of molecules undergoing rapid exchange between diamagnetic and paramagnetic environments is well understood and is exemplified in studies of fast electron transfer between an or...
Analysis of ENPP2 in the Uterine Endometrium of Pigs Carrying Somatic Cell Nuclear Transfer Cloned Embryos
Pig Pregnancy ENPP2 LPA SCNT
2016/5/12
Somatic cell nuclear transfer (SCNT) is a useful tool for animal cloning, but the efficiency of producing viable offspring by SCNT is very low. To improve this efficiency in the production of cloned p...

Heavy fermions get nuclear boost on way to superconductivity
Heavy fermions nuclear boost superconductivity
2016/2/22
In a surprising find, physicists from the United States, Germany and China have discovered that nuclear effects help bring about superconductivity in ytterbium dirhodium disilicide (YRS), one of the m...
PREDICTING NUCLEAR GENE COALESCENCE FROM MITOCHONDRIAL DATA: THE THREE-TIMES RULE
molecular systematics monophyly whales
2015/12/17
Coalescence theory predicts when genetic drift at nuclear loci will result in fixation of sequence differences
to produce monophyletic gene trees. However, the theory is difficult to appl...
Contrasting Population Structure from Nuclear Intron Sequences and mtDNA of Humpback Whales
Nuclear Intron Sequences mtDNA
2015/12/17
Powerful analyses of population structure require information from multiple genetic loci. To help develop a
molecular toolbox for obtaining this information, we have designed universal oligonucleoti...
Surface Nuclear Magnetic Resonance (SNMR) - A new method for exploration of ground water and aquifer properties
surface NMR ground water aquifer assessment hydrogeophysics
2015/9/29
The Surface Nuclear Magnetic Resonance (SNMR) method is a fairly new technique in geophysics to assess ground water, i.e. existence, amount and productibility by measurements at the surface. The NMR t...
