Patterning of neural stem cells on poly(lactic-co-glycolic acid) film modified by hydrophobin
Colloids Surf. B Biointerfaces 74(1) , 370-4, (2009) Patterning of neural stem cells (NSCs) is of great importance for its potential applications in the therapy of nerve injuries. Due to the critical requirements and the great difficulty in NSCs cultivation, developing new methods for NSCs patterning is very ch... |

Biomonitoring of exposure to lewisite based on adducts to haemoglobin.
Arch. Toxicol. 74(4-5) , 207-14, (2000) The development of a procedure for retrospective detection and quantitation of exposure to the arsenical dichloro(2-chlorovinyl)arsine (lewisite; L1) has been initiated. Upon incubation of human blood with [14C]L1 (20 nM-0.2 mM) in vitro, more than 90% of the... |

Identification of dihydroetorphine in biological fluids by gas chromatography-mass spectrometry.
J. Chromatogr. B, Biomed. Appl. 667(2) , 344-8, (1995) A method for the monitoring of dihydroetorphine hydrochloride, a powerful anaesthetic and analgesic drug, in biological fluids was developed, involving GC-MS with multiple selected-ion monitoring. Dihydroetorphine was extracted from human blood and urine with... |

Improvements in monitoring the N-terminal valine adduct in human globin after exposure to sulfur mustard and synthesis of reference chemicals.
Talanta 85(2) , 1154-9, (2011) The N-terminal valine adduct (HETE-Val) in globin is believed to behave as a long-lived biomarker after exposure to sulfur mustard (HD). Development of a highly sensitive method for monitoring HETE-Val, particularly at low HD exposure levels or for retrospect... |

Bioseparation of recombinant proteins from plant extract with hydrophobin fusion technology.
Methods Mol. Biol. 824 , 527-34, (2012) Two main hurdles hinder the widespread acceptance of plants as a preferred protein expression platform: low accumulation levels and expensive chromatographic purification methods. Fusion of proteins of interest to fungal hydrophobins has provided a tool to ad... |

Gas-liquid chromatographic method for the assay of aminoglycoside antibiotics in serum.
J. Chromatogr. A. 151(2) , 133-46, (1978) A gas-liquid chromatographic (GLC) method is presented for the rapid analysis of gentamicin, tobramycin, netilmicin, and amikacin from human serum. This procedure may have application to all aminoglycoside drugs. The three isomers of gentamicin are resolved a... |
