Magnetoplasma effects on wave interactions in semiconductors are discussed.The chapter discusses the positive and negative cyclotron resonance absorption by weakly relativistic electrons and provides background description of the electron cyclotron maser.
The modified ligase enhances discrimination in a number of ways, for example, the ligase may increase the difference in the on rates and/or the off rates between a perfect match product and a mismatch product (a kinetic effect); or the ligase may increase the binding energy difference between a perfect match and a mismatch (a free energy [ΔG] effect); or the ligase may itself discriminate between perfect matches and mismatches (ΔG or kinetic effect); or some combination of these and other factors.1.
A method for andyzing a target nucleic acid, comprising the steps of: providing an array of a plurality of fixed oligonucleotide probes; providing a plurality of labeled oligonucleotide probes; contacting the target nucleic acid w h the fixed probes and the labeled probes under conditions that dlow the probes which form perfect matches with the target nucleic acid to be distinguished from the probes bound with an end mismatch to the target nucleic add, wherdn a modified ligase is added which increases the discrimination of the perfect match from the end mismatch; covdently joining the fixed probe, bound at a site in the target nucleic acid, to the labeled probe, which is hybridized to a sire on the target nudeic acid that is adjacent to the site on which the fixed probe is bound; and identifying the fixed probes and the labeled probes that are covalenily joined.
ENHANCED DISCRIMINATION OF PERFECT MATCHES FROM MISMATCHES USING A MODIFIED DNA LIGASE TTET.
The role of gangliosides in preventing neuronal degeneration was examined in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced mouse parkinsonian model.
Intraventricular injections of a ganglioside mixture prior to MPTP treatment reduced MPTP's toxicity on tyrosine hydroxylase-positive neurons in the substantia nigra.
This raises the interesting possibility that early ganglioside administration may be beneficial in the treatment of neurodegenerative disorders.
This chapter discusses the cyclotron resonance with free electrons and carriers in solids.
The chapter is concerned with the solutions of the classical and quantum-mechanical equations, describing the motion of an electron in a homogeneous magnetic field.
It introduces the effects of the environment with which the electron interacts through scattering collisions, and incorporates the effect of the potential of a periodic lattice of neighboring ions by introducing an effective mass of an electron in a solid.
The measurement of effective mass by cyclotron resonance methods gives a measure of the curvature of the energy-momentum characteristic, which adds on to the understanding of the band structure in semiconductors.
Various cyclotron resonance techniques and observations are described.
