Thrombosis during all-trans-retinoic acid therapy in a child with acute promyelocytic leukemia and factor VQ 506 mutation
(Taylor & Francis Inc, 2000)
Acute promyelocytic leukemia (APL) is often associated with a severe hemostatic disorder, caused bg the release of procoagulant and fibrinolytic substances from leukemic blasts. The coagulation profile may exhibit disseminated ...
Structure and conformation of 2,3,4-triphenyl-1-oxa-4-azabutadiene
(Elsevier Science Bv, 2000)
2,3,4-triphenyl-1-oxa-4-azabutadine (C20H15NO) has been studied by X-ray analysis and AMI molecular orbital methods. It crystallises in the triclinic space group P-l with a = 9.414(3), b = 10.479(3), c = 8.385(2) Angstrom, ...
Dithiocarbamate-incorporated monosize polystyrene microspheres for selective removal of mercury ions
(Elsevier Science Bv, 2000)
Dithiocarbamate-incorporated monosize polystyrene based microspheres (2 mu m in diameter) were used for selective removal of Hg(II) from aqueous solutions containing different amounts of Hg(II) (10-100 ppm). Adsorption ...
Controlled release of aldicarb from lignin loaded ionotropic hydrogel microspheres
(Taylor & Francis Ltd, 1999)
Aldicarb loaded microspheres of carboxymethyl cellulose, CMC, of various compositions were prepared with the crosslinking action of AI(III). Into these microspheres, lignin was introduced as a filler to further regulate ...
Removal of cadmium(II) ions from human plasma by thionein modified pHEMA based membranes
(Elsevier Science Bv, 2000)
Microporous poly(2-hydroxyethylmethacrylate) [pHEMA] membranes carrying Cibacron Blue F3GA and/or thionein were prepared and used for cadmium(II) removal from human plasma. pHEMA membranes were produced by a photopolymerization ...
β-galactosidase immobilization into poly(hydroxyethyl methacrylate) membrane and performance in a continuous system
(Wiley-Blackwell, 1999)
The activity of beta-galactosidase immobilized into a poly(2-hydroxyethyl methacrylate) (pHEMA) membrane increased from 1.5 to 10.8 U/g pHEMA upon increase in enzyme loading. The K-m values for the free and the entrapped ...
Epoxy-derived pHEMA membrane for use bioactive macromolecules immobilization: Covalently bound urease in a continuous model system
(John Wiley & Sons Inc, 2000)
Poly(2-hydroxyethylmethacrylate) (pHEMA) membranes were prepared by W-initiated photopolymerization of HEMA in the presence of an initiator (alpha-alpha '-azobisisobutyronitrile, AIBN). The epoxy group, i.e., epichlorohydrin, ...
Improving performance of switched reluctance motor by fuzzy logic controller
(John Wiley & Sons Ltd, 1999)
This paper presents torque ripple minimization of a switched reluctance motor (SRM) by using a fuzzy controller, The nonlinear model of the SRM and the mathematical model of the converter circuit are driven. The motor used ...
Isolation and identification of motile Aeromonas spp. in ground beef
(Scientific Technical Research Council Turkey, 2000)
In this study, a total of 100 ground beef samples purchased at different butchers' shops and supermarkets in Ankara including 50 samples obtained from butchers' shops and 50 samples obtained from supermarkets, were analysed ...
Immobilization of polyphenol oxidase on carboxymethylcellulose hydrogel beads: preparation and characterization
(John Wiley & Sons Ltd, 2000)
Carboxymethylcellulose (CMC) beads were prepared by a liquid curing method in the presence of trivalent ferric ions, and epicholorohydrin was covalently attached to the CMC beads. Polyphenol oxidase (PPO) was then covalently ...
