Synthesis, structure, and solution properties of benzoannelated cryptands.
(2006)
Cryptands An2.2.1 and An2.2.2 were synthesized by high dilution techniques. Attempts to produce An3.1.1 gave primarily the 2 + 2 addition product An3.1.1.3. X-ray crystallography, ESI-MS, and NMR techniques were used to ...
Development of methodology for the determination of catecholamines, indoleamines, and related hydroxylating enzymes.
(1980)
This study was concerned with the development and improvement of analytical procedures using liquid chromatography with electrochemical detection for the determination of activity of tyrosine hydroxylase, tryptophan ...
Using Novel Data Analysis Methods to Extract Information from Mass Spectrometry Imaging and Single Cell Mass Spectrometry Results
(2023-12-15)
Mass spectrometry (MS) is a powerful tool for qualitative and quantitative biological sample analysis, with its high sensitivity, broad applicability, and strong robustness. While insights into ‘what’ and ‘how’ can be ...
Investigations of the effects of iron, manganese, and nickel on the properties of sulfated zirconia catalysts.
(1997)
Thermogravimetry (TG) was utilized to study catalyst thermal stability and to measure sulfate contents for catalysts with differing compositions. Temperature programmed desorption (TPD) measurements of surface adsorbed ...
Optimization of liquid chromatography with electrochemical detection of three micron reversed-phase column for neurochemical determinations /
(1984)
Liquid chromatography with electrochemical detection has become an established technique for the determination of catecholamines, indoleamines, and related enzymes. Previous work in this area has utilized lower efficiency ...
A study of the use of Kelex 100 for removal of cadmium using ligand-modified micellar-enhanced ultrafiltration.
(1999)
Ligand-modified micellar-enhanced ultrafiltration (LM-MEUF) is a membrane based separation method for removal of metal ions from aqueous solutions. An amphilic ligand which will selectively complex the target ion is ...
Complexation studies of 5,5'-dinitro BAPTA and Mag-quin-1, with the divalent cations of cadmium, lead, zinc, copper, nickel, and calcium.
(1999)
Log values for the first three stepwise, mixed-mode protonation constants of MQ1 are: log KH1 = 7.57 +/- 0.01, log KH2 = 3.73 +/- 0.01, and KH3 = 2.41 +/- 0.02 at I = 0.05 (TEAP). Log values for the 1:1 metal to MQ1 complex ...
Neurochemical and immunohistochemical effects induced by the 1-methyl-4-phenylpyridinium animal model of Parkinson's disease: An in vivo microdialysis investigation in freely moving rats.
(2003)
Parkinson's disease (PD) is a neurodegenerative disorder which afflicts more than 1 million Americans with an estimated 50,000 new diagnoses each year. 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) causes parkinsonian ...
