7/2/2008Neuregulin-1 (Nrg1)/erbB signaling regulates neuronal development migration myelination and synaptic maintenance The Nrg1 gene is a schizophrenia susceptibility gene To understand the contribution of Nrg1 signaling to adult brain structure and behaviors we studied the regulation of type III Nrg1 expression and evaluated the effect of decreased expression of the type III Nrg1 isoforms

4/28/2020The NMR data (1 H and 13 C NMR spectra) of trisaccharide 1 are in agreement with those of the isolated polysaccharide (Jones 2005) (for details see Supplementary Material Table S1) The slight spectral differences are most evident toward the reducing end and probably arise due to the installation of aminopropyl linker in the synthetic

3/20/2020Neurons have a membrane periodic skeleton (MPS) composed of actin rings interconnected by spectrin Here combining chemical and genetic gain- and loss-of-function assays we show that in rat hippocampal neurons the MPS is an actomyosin network that controls axonal expansion and contraction

13 C-labeled glycine and nuclear magnetic resonance (NMR) were applied to investigate uptake and potential storage products when activated sludge was fed with glycine under anaerobic conditions Glycine was consumed by the biomass and the majority was stored intracellularly as free glycine and fermentation products

NMR (nuclear magnetic resonance) could be used in some special cases for relatively small polymers If the end of the polymer has a detectable signal then the strength of that signal can tell you how much of the polymer is end and how much is middle For example if a polymer is A-B-B-B-B-B-B-B-B-C where A and C are end groups and B is the
