Disease relevance of Chromatography, High Pressure Liquid

 

Psychiatry related information on Chromatography, High Pressure Liquid

  • In patients, we assessed detailed psychopathology and neuropsychological performance and determined serum levels of haloperidol, clozapine and its two main metabolites desmethylclozapine and clozapine metabolite N-oxid by HPLC [6].
  • Both the amount of MAA utilized in the preparation and reaction time affect the selectivity of chromatographic separation in both the HPLC and the CEC mode and electroosmotic flow [7].
  • Therefore, using a chromatographic HPLC method, the regional distribution of free D-aspartate levels in post-mortem human brain samples from patients with Alzheimer's disease (AD) (n = 5) and age-matched controls (n = 5) were determined [8].
  • The plasma amisulpride levels of 85 patients with schizophrenia or schizoaffective disorder (mean age: 34.0+/-11.4 years; 40 women, 45 men) were assessed by high-performance liquid chromatography (HPLC) with fluorometric detection [9].
  • Dopamine D1 receptors were upregulated bilaterally in the LPO following avoidance learning and this response was not accompanied by significant changes in the level of dopamine or its metabolites (HVA, DOPAC), as revealed by HPLC chromatography of brain samples dissected from the LPO of control and trained chicks [10].
 

High impact information on Chromatography, High Pressure Liquid

  • We report here that triamcinolone acetonide (TA) promotes the transformation of 8S-GR to 4S-GR complexes both in explants and in cell-free conditions and that the high-affinity antiglucocorticosteroid RU 486 stabilizes the 8S-GR, as assessed by gradient sedimentation and HPLC [11].
  • As the opportunity of examining pancreatic tissue from patients suspected of secreting insulin variants is rare, we have developed a method combining HPLC and radioimmunoassay to identify insulin variants isolated from human sera [12].
  • We report here that rat dorsal root ganglia incorporate 35S-methionine into substance P, characterised as authentic by immunoprecipitation followed by HPLC [13].
  • We report here that this CCK-like immunoreactive substance co-chromatographs with CCK8 sulphate on Sephadex G-50 and two HPLC chromatographic systems [14].
  • Vasoactive intestinal peptide (VIP) labeled with 125I, [Tyr10-125I]VIP, can be hydrolyzed by immunoglobulin G (IgG) purified from a human subject, as judged by trichloroacetic acid precipitation and reversed-phase high-performance liquid chromatography (HPLC) [15].

Associations of Chromatography, High Pressure Liquid with chemical compounds

  • Reverse-phase HPLC was also used to isolate the variant tryptic peptide of beta-T13 that has alanine replacing valine at residue 126 [31].
  • Physicians should be aware of possible product changes being made by manufacturers of levothyroxine products over the next year or so as more companies switch to the HPLC method [32].
  • No lipoxygenase metabolites are detected by HPLC and RIA if purified PMN are stimulated by either GM-CSF or chemotactic factors in the absence of exogenous arachidonate [33].
  • Further analysis of the labeled nucleotides by HPLC indicated that adenine and adenosine are converted only to adenine nucleotides whereas guanine and guanosine are only incorporated into guanine nucleotides [34].
  • MDF was purified 6,140-fold by a seven-step procedure: extraction with acid-ethanol; precipitation with ether; and fractionation on gel filtration, anion-exchange, diphenyl reversed-phase and C4 reversed-phase HPLC columns, the last column twice [35].
 

Gene context of Chromatography, High Pressure Liquid

  • To analyze whether HLA-E binds peptides and to identify the corresponding ligands, fractions of acid-extracted material from HLA-E/X63 transfectants were separated by reverse phase HPLC and were tested for their ability to enhance HLA-E cell surface expression [36].
  • The mobility of the ovarian IrCRH molecule was similar to that of rat/human CRH by reverse phase HPLC [37].
  • Reverse-phase HPLC of aorta and vena cava extracts revealed a single peak corresponding to the amidated OT nonapeptide [38].
  • By using denaturing HPLC, these two genes, as well as DBY and DFFRY, were screened for polymorphic sites in 53-72 representatives of the five continents [39].
  • HPLC showed immunoreactive CRH extracted from RA and OA synovial tissues and fluids coeluted with CRH 1-41 [40].
 

Analytical, diagnostic and therapeutic context of Chromatography, High Pressure Liquid

  • Glomerular LTB4 synthesis by CBGG-injected rats was confirmed by radiometric HPLC and by gas chromatography mass-spectroscopy (GC-MS) analysis [41].
  • Biologically active and inactive HPLC fractions of Ox-PAPC were compared by fast atom bombardment-mass spectrometry which revealed that active fractions possessed ions with a mass to charge [correction of change] ratio greater than native PAPC by multiples of 16 D suggesting the addition of 3 and 4 oxygen atoms to PAPC [42].
  • A protein factor that binds to pOTC but not to mature OTC and was named presequence binding factor or PBF, was purified 91,000-fold from the lysate by affinity chromatography using pOTC-bound Sepharose, DEAE-5PW HPLC and sucrose gradient centrifugation [43].
  • Proteins are digested with trypsin and the resulting peptides are then converted to methyl esters, enriched for phosphopeptides by immobilized metal-affinity chromatography (IMAC), and analyzed by nanoflow HPLC/electrospray ionization mass spectrometry [44].
  • The factor, provisionally termed keratinocyte growth factor (KGF) because of its predominant activity on this cell type, was purified to homogeneity by a combination of ultrafiltration, heparin-Sepharose affinity chromatography, and hydrophobic chromatography on a C4 reversed-phase HPLC column [45].
