The clinical utility of routine electroencephalography (EEG) after a first unprovoked seizure remains uncertain. Its diagnostic accuracy in identifying adults and children with new onset epilepsy was examined. A systematic review and meta‐analysis of studies examining individuals who underwent routine EEG after a first unprovoked seizure and were followed for seizure recurrence for at least 1 year...
ObjectiveTo describe the diagnostic accuracy of screening questionnaires to identify epilepsy in adults, we performed a systematic review of diagnostic studies that assessed the sensitivity and specificity of such screening questionnaires as compared to a physician's clinical assessment.
MethodsWe searched Ovid MEDLINE (1946 to present) and Ovid EMBASE (1947 to present) for studies that estimated...
The properties of polyesteramides based on PET and nylon 2,T (PETA) using DMT, the bis(esterdiamide) T2T-dimethyl (N,N'-bis(p-carbo-methoxybenzoyl)ethanediamine) and 1,2-ethanediol as starting materials has been studied. A PETA series with an increasing T2T content (0.1-30mol%) has been synthesised and studied. It was observed by dynamic mechanical analysis, that the T g , flow temperature...
The synthesis and the thermal stability of polyesteramides based on PET and nylon 2,T (PETA) using DMT, T2T-dimethyl (N,N'-bis(p-carbo-methoxybenzoyl)ethanediamine) and 1,2-ethanediol as starting materials has been studied. The catalysts that were used are tetraisopropyl orthotitanate, manganese acetate, zinc acetate, antimony trioxide and caesium carbonate. After a short melt polymerisation at 270-290...
The synthesis of the bisesterdiamide T2T-dimethyl (one-and-a-half repeating unit of nylon 2,T) (benzoic acid, 4,4'-[1,2-ethanediylbis(iminocarbonyl)] bis-dimethyl ester, CAS no 7060-10-8) has been studied using dimethyl terephthalate (DMT) and 1,2-diaminoethane (DAE) as starting materials. T2T-dimethyl was synthesised in a solvent mixture of toluene/methanol at 65 o C employing lithium or...
Alternating copolyesteramides (APEA's) consisting of mixtures of 1,4-butyleneterephthalamide ester (N,N -bis(p-carbomethoxybenzoyl) diaminobutane) and 1,4-butyleneisophthalamide ester (N,N -bis(m-carbomethoxybenzoyl) diaminobutane) polymerized with ethanediol were synthesised in an ethanediol solution. The bisesterdiamides were prepared from 1,4-butanediamine and dimethyl terephthalate or dimethylisophthalate...
