We studied three lines of oxytocin (Oxt) and oxytocin receptor (Oxtr) knockout (KO) male mice [Oxt(-/-), total Oxtr(-/-) and partial forebrain Oxtr (Oxtr(FB/FB))] with established deficits in social recognition to further refine our understanding of their deficits with regard to stimulus female's strain. We used a modified social discrimination paradigm in(More)
BACKGROUND AND PURPOSE Capsaicin, an agonist of transient receptor potential vanilloid 1 (TRPV1) channels, is pro-nociceptive in the periphery but is anti-nociceptive when administered into the ventrolateral periaqueductal gray (vlPAG), a midbrain region for initiating descending pain inhibition. Here, we investigated how activation of TRPV1 channels in the(More)
Oxytocin (Oxt) and vasopressin (Avp) are important for a wide variety of behaviors and the use of transgenic mice lacking the peptides or their receptors, particularly when their loss is spatially and temporally manipulated, offers an opportunity to closely examine their role in a particular behavior. We used a cued fear conditioning paradigm to examine(More)
We propose that obsessions are categorized into two subtypes, i.e. autogenous obsessions and reactive obsessions, which are different in terms of identifiability of their evoking stimuli, subjective experiences, contents, and subsequent cognitive processes. Autogenous obsessions tend to come abruptly into consciousness without identifiable evoking stimuli,(More)
BACKGROUND Few reports discuss the optimal management of patients diagnosed with tuberculosis (TB) before scheduled stem cell transplantation (SCT), who then proceed with transplantation. METHODS We found 13 patients with TB before SCT (proven, n = 9; probable, n = 3; possible, n = 1) in the medical records of our institution. RESULTS Most of the(More)
A scanning electron microscopic study was performed to observe the surface ultrastructures of the third-stage larvae of Gnathostoma hispidum. The early third-stage larvae (EL3) were collected from the viscera of Chinese loaches by the artificial digestion method. The advanced third-stage larvae (ADL3) were recovered from mice experimentally infected with(More)
