Lykkesfeldt, Jens, 2000: Determination of ascorbic acid and dehydroascorbic acid in biological samples by high-performance liquid chromatography using subtraction methods: Reliable reduction with tris(2-carboxyethyl)phosphine hydrochloride. Determination of dehydroascorbic acid in biological samples most commonly involves indirect measurement. The concentration is calculated by subtraction of the measured ascorbic acid concentration from that of total ascorbic acid analyzed after red...

Cruza, J.F.; Camacho, J.; Serrano-Iribarnegaray, L.; Fritsch, C., 2013: New method for real-time dynamic focusing through interfaces. In nondestructive evaluation (NDE) a coupling medium (wedge) is frequently inserted between the array probe and the object being evaluated. In this situation, focal law computing is complicated by the refraction effects at the interface. Furthermo...

Infection has long been suspected as a possible factor in the aetiology of leukaemia and lymphoma. If seasonal variation in the onset of disease could be shown in any of the diagnostic subgroups of leukaemia or lymphoma, this would provide support...

Zhu Cheng; Zeng GuangWen, 1996: Effects of spermine and spermidine on germination of rice seeds and their relation to temperature. Rice (Oryza sativa) cv. Jiashan 222 seeds were treated with 0.01-1.0 mmol/litre spermine (spm) or spermidine (spd) and germinated at different temperatures. Seed germination was increased by polyamines at 16 degrees C, but no effect was observed a...

Perrini, P.; Lanzino, G., 2006: The association of venous developmental anomalies and cavernous malformations: pathophysiological, diagnostic, and surgical considerations. Developmental venous anomalies (DVAs) are often associated with intracranial cavernous malformations (CMs). The frequency of this association and the observation of de novo CMs located near a known, preexisting DVA raise speculations as to the pos...

Flynn F.W.; Berridge K.C.; Grill H.J., 1986: Preabsorptive and postabsorptive insulin secretion in chronic decerebrate rats. Basal, taste-stimulated (preabsorptive), and postabsorptive insulin secretion and plasma glucose responses were studied in chronic decerebrate rats and their pair-fed neurologically intact controls. In experiment 1, preabsorptive insulin response...

Yanchenko, V.I., 1981: Study of a collection of Triticum dicoccum in the Altai region. Of 456 forms studied during 1978-79, the earliest were those of subsp. abyssinicum and the latest those of subsp. dicoccum. Several high-yielding forms with a long emergence-heading period and a short heading-ripening period are listed as useful m...
