Chelate extraction of transition metal ions by ethylene diamine diacetic acid with n-substituted octadecyl groups
(Taylor & Francis Inc, 2002)
An organic-soluble chelating agent NN'-di-n-octadecyl ethylenediamine-NN'-diacetic acid (DOED) has been synthesized in two steps by (i) condensation of dibromoethane with 1-amino octadecane (octadecylamine) and (ii) ...
Metalization of polymer beads via polymer-supported hydrazines as reducing agents
(John Wiley & Sons Inc, 2002)
A new method for depositing metal onto a polymer surface has been developed in which the metal coating of polymer beads is performed with hydrazine functions as reducing agents on the surface of the polymer itself. In this ...
Prospective evaluation of platelets prepared by single and random methods during 5 days of storage: aspects related to quality and quantity
(Pergamon-Elsevier Science Ltd, 2002)
Platelets which have an important role in hemostatic mechanisms and which were prepared by single and random methods were investigated to measure quantity and aggregation response during 5 days of storage. The aggregation ...
Primary epiploic appendagitis: MRI findings
(Elsevier Science Inc, 2002)
Primary epiploic appendagitis (PEA) occurs secondary to inflammation of an epiploic appendage and is considered to be a rare cause of acute abdomen. In this case report we describe the magnetic resonance imaging (MRI) ...
Reconstruction of the superior labial sulcus in secondary bilateral cleft lip deformities: An inverted U-shaped flap
(Lippincott Williams & Wilkins, 2001)
A shallow buccal sulcus deformity following bilateral cleft lip repair is not rare. A variety of techniques are described for the secondary reconstruction of a deficient sulcus. Most of these are associated with a variable ...
New pyrazoline bearing 4(3H)-quinazolinone inhibitors of monoamine oxidase: Synthesis biological evaluation and structural determinants of MAO-A and MAO-B selectivity
(Pergamon-Elsevier Science Ltd, 2009)
A new series of pyrazoline derivatives were prepared starting from a quinazolinone ring and evaluated for antidepressant anxiogenic and MAO-A and -B inhibitory activities by in vivo and in vitro tests respectively. Most ...
A hybrid approach to concept selection through fuzzy analytic network process
(Pergamon-Elsevier Science Ltd, 2009)
Evaluating conceptual design alternatives in a new product development (NPD) environment has been one of the most critical issues for many companies which try to survive in the fast-growing world markets. Therefore most ...
Histone Deacetylase Inhibition Activity and Molecular Docking of (E )-Resveratrol: Its Therapeutic Potential in Spinal Muscular Atrophy
(Wiley, 2009)
Spinal muscular atrophy is an autosomal recessive motor neuron disease that is caused by mutation of the survival motor neuron gene (SMN1) but all patients retain a nearly identical copy SMN2. The disease severity correlates ...
Oxygen diffusion into polystyrene-bentonite films
(Elsevier, 2009)
A simple fluorescence technique is proposed for the measurement of the diffusion coefficient of oxygen into polystyrene-clay composite films. The composite films were prepared from the mixture of surfactant-free pyrene ...
In situ steady state fluorescence (SSF) technique to study drying of PAAm hydrogels made of various cross-linker contents
(Elsevier Science, 2009)
Drying experiments of polyacrylamide (PAAm) gels were performed using steady-state fluorescence (SSF) spectrometer. Pyranine (P) was introduced as a fluorescence probe and intensity of P from various crosslinker content ...
