Nitric oxide synthases (NOSs) have been shown to participate in the mechanism of the antinociceptive action of tapentadol. The results obtained in this study indicate that tapentadol administered intrathecally at a range of doses (30-100 µg) increased nociceptive thresholds in the Randall-Selitto and tail-flick tests in rats; however, this effect was(More)
AIM To assess the relationship between stereoscopic vision, visual perception, and microstructure of the corpus callosum (CC) and occipital white matter, 61 children born with a mean birth weight of 1024 g (SD 270 g) were subjected to detailed ophthalmologic evaluation, Developmental Test of Visual Perception (DTVP-3), and diffusion tensor imaging (DTI) at(More)
Biphalin, a synthetic opioid octapeptide with a palindromic sequence has high analgesic activity. Biphalin displays a strong affinity for μ and δ-opioid receptors, and a significant to κ-receptor. The paper reports the synthesis of novel analogs of biphalin containing β(3)-homo-amino acid residues at the 4,4' positions and a hydrazine or(More)
