O-desmethyl tramadol is one of the main metabolites of tramadol. It has been widely used clinically and has analgesic activity. Muscarinic receptors are involved in neuronal functions in the brain and autonomic nervous system, and much attention has been paid to these receptors as targets for analgesic drugs in the central nervous system. We have reported(More)
Hypotaurine is an intermediate in taurine biosynthesis from cysteine in astrocytes. Although hypotaurine functions as an antioxidant and organic osmolyte, its physiological role in the central nervous system remains unclear. This study used behavioral assessments to determine whether hypotaurine influenced nociceptive transmission in acute, inflammatory,(More)
Chlorogenic acid (CGA), one of the most abundant dietary polyphenols, is known to have various physiological properties. Although CGA is reported to have an antinociceptive effect on acute and inflammatory pain, little is known about its effect on neuropathic pain or its action site. The aim of the present study was to determine whether intrathecally(More)
Luteolin, a major component of flavones, is known to have various physiological properties. Although luteolin reportedly has an antinociceptive effect on acute and inflammatory pain, little is known about its effect on neuropathic pain. The aim of the present study was to determine whether luteolin could ameliorate hyperalgesia in the central nervous system(More)
Self-luminous light sources in the real world often have non-negligible sizes and radiate light inhomogeneously. Acquiring the model of such a light source is highly important for accurate image synthesis and understanding. In this paper, we propose a method for measuring 4D light fields of self-luminous extended light sources by using a liquid crystal (LC)(More)
UNLABELLED We examined the reliability of an airway evaluation test to assess the occipitoatlantoaxial (OAA) extension capacity described by Bellhouse et al. (Bellhouse test) in 20 adult volunteers with normal cervical spines. Each subject sat upright with the head in the neutral position and was then asked to extend the head maximally while attempting to(More)
