We have performed the first genome-wide analysis of the Inverted Repeat (IR) structure in the human genome, using a novel and efficient software package called Inverted Repeats Finder (IRF). After masking of known repetitive elements, IRF detected 22,624 human IRs characterized by arm size from 25 bp to >100 kb with at least 75% identity, and spacer length(More)
It has been hypothesised that the massive accumulation of L1 transposable elements on the X chromosome is due to their function in X inactivation, and that the accumulation of Alu elements near genes is adaptive. We tested the possible selective advantage of these two transposable element (TE) families with a novel method, interruption analysis. In(More)
The constant bombardment of mammalian genomes by transposable elements (TEs) has resulted in TEs comprising at least 45% of the human genome. Because of their great age and abundance, TEs are important in comparative phylogenomics. However, estimates of TE age were previously based on divergence from derived consensus sequences or phylogenetic analysis,(More)
In light of evidence suggesting the proinflammatory and nociceptive action of peripheral serotonin (5-HT), the present study examined dose-dependent parameters of edema and algesia produced by intraplantar injections of 5-HT and the role of heterogeneous 5-HT receptors in these 5-HT-induced responses. Intraplantar 5-HT (0.05, 0.25, 0.5, or 1.0 mumols)(More)

The present study examined developmental patterns of antinociception mediated by the spinal 5-HT3 receptor system in the neonatal rat. Intrathecally administered 2-methylserotonin (25-100 micrograms) first produced antinociception against formalin-induced acute inflammatory pain at 10 days postnatally, with effect only at the peak dose (100 micrograms).(More)
Although morphine typically produces analgesia in a variety of species, recent research has identified a biological model in which morphine produces a naloxone-reversible, paradoxical hyperalgesic response to a noxious thermal stimulus in young domestic fowl. The present study examined opioid receptor-mediation of this atypical opiate effect. Patterns of(More)
