Single-walled carbon nanotubes (SWCNTs) were purified by treatment with concentrated nitric acid and then subjected to Soxhlet extraction with tetrahydrofuran (THF). The THF extract of low molecular weight carboxylated carbons was derivatized with (t

Histone acetylation and methylation play a critical role in transcription and gene regulation. Identification of sites of lysine acetylation and methylation in histones or other proteins by mass spectrometry (MS) is of increasing interest. In this pa

Glial uptake of neurotransmitter glutamate (GLU) from the extracellular fluid was studied in vivo in rat brain by 13C NMR and microdialysis combined with gas-chromatography/mass-spectrometry. Brain GLU C5 was 13C enriched by intravenous [2,5-13C]gluc

Extracellular glutamate (GLU(ECF)) was collected by microdialysis from the corticostriatal region of awake rats, at the basal level and after elevation by perfusion of GLU uptake inhibitor, L-trans-pyrrolidine-2,4-dicarboxylic acid. Concurrently, [2,

Ion-neutral complexes, well attested as intermediates in the expulsion of alkenes from M +. and MH + ions from primary alkyl phenyl ethers, are shown to intervene in the decomposition of the MH + ion of a secondary alkyl phenyl ether, (CD 3 ) 2 CHOPh

The rate of glutamate synthesis from leucine by the branched-chain aminotransferase was measured in rat brain in vivo at steady state. The rats were fed exclusively by intravenous infusion of a nutrient solution containing [15N]leucine. The rate of g

The fragmentation pathways of a series of 18 dinitrofluoranthenes (DNF) and four trinitrofluoranthenes have been studied under electron impact conditions. In general, multiple losses of NO2, NO and CO from the molecular ion were observed. Quinonoid i
