The activity of superoxide dismutase was investigated in needles of spruce trees. To obtain maximum activity, needles were homogenized in the presence of Triton X-100 and polyvinylpyrrolidone. Superoxide dismutase activity was measured in dialyzed extracts with a modified epinephrine assay (HP Misra, I Fridovich [1972] J Biol Chem 247: 3170-3175) at pH(More)
Research has shown that people fail to report the presence of the auditory component of suprathreshold audiovisual targets significantly more often than they fail to detect the visual component in speeded response tasks. Here, we investigated whether this phenomenon, known as the "Colavita effect", also affects people's perception of visuotactile stimuli as(More)
Partial deletion of the long arm of chromosome 5, del(5q), is the cytogenetic hallmark of the 5q-syndrome, a distinct subtype of myelodysplastic syndrome-refractory anemia (MDS-RA). Deletions of 5q also occur in the full spectrum of other de novo and therapy-related MDS and acute myeloid leukemia (AML) types, most often in association with other chromosome(More)
We have constructed a physical and transcript map of 5q31.3-qter. The contig comprises 173 yeast artificial chromosomes (YACs) to which 159 sequence tagged sites (STSs), 47 expressed sequence tags (ESTs), and 32 genes were assigned. Previously published partial YAC contigs of the region have been refined and integrated. Given that the region contains 25 Mbp(More)
The dysfunction of the hypothalamic-pituitary-gonadal axis in old age was studied in 24-month old male Wistar rats which were compared with 3-month old animals. The hypothalamic LH-RH content and the pituitary LH were significantly lower in the old than in the young adult animals. The plasma concentrations of LH and testosterone were significantly higher in(More)
