Languages differ with respect to how aspects of motion events tend to be lexicalized. English typically conflates MOTION with MANNER, but Japanese and Spanish typically do not. We report a set of experiments that assessed the effect of this cross-linguistic difference on participants' decisions in a similarity-judgment task about scenes containing novel(More)
We have previously shown that the rat follitropin receptor (rFSHR) expressed in transfected cells becomes phosphorylated upon stimulation of the cells with agonist or a phorbol ester. Peptide mapping and mutagenesis studies have also shown that the agonist- or phorbol ester-induced phosphorylation of the rFSHR maps to Ser/Thr residues present in the first(More)
We measured endogenous overflow of acetylcholine (ACh) from a vascularly perfused rat stomach in vitro with modified Krebs-Ringer solution containing 100 microM physostigmine. Evoked ACh overflow by vagal stimulation at 2.5 Hz for 2 min was abolished by tetrodotoxin (3 x 10(-7) M) or Ca++ removal and reduced by hexamethonium (10(-4) M). The evoked overflow(More)
Survival of cerebellar granule cells (CGC) in culture was significantly improved in the presence of cholera toxin B subunit (Ctx B), a ligand which binds to GM1 with specificity and high affinity. This trophic effect was linked to elevation of intracellular calcium ([Ca2+]i), and was additive to that of high K+. Survival was optimized when Ctx B was present(More)
BACKGROUND AND PURPOSE Haemopressin and RVD-haemopressin, derived from the haemoglobin α-chain, are bioactive peptides found in brain and are ligands for cannabinoid CB1 receptors. Activation of brain CB1 receptors inhibited the secretion of adrenal catecholamines (noradrenaline and adrenaline) induced by i.c.v. bombesin in the rat. Here, we investigated(More)
Receptors for granulocyte colony-stimulating factor (G-CSFRs) have been confirmed on the cell surfaces of several non-haematopoietic cell types, including bladder cancer cells. This observation has naturally led to the hypothesis that the expression of G-CSFR on these cells may enhance their growth by G-CSF. In this study, the expression of G-CSFR was(More)
We tried to characterize nicotinic acetylcholine receptors involved in the release of catecholamines from the rat adrenal gland. The isolated adrenal gland was retrogradely perfused via the adrenal vein with Krebs-Ringer solution at a flow rate of 0.5 ml/min. Endogenous catecholamines, adrenaline and noradrenaline, released into the perfusate were(More)
The adrenal glands and sympathetic celiac ganglia are innervated mainly by the greater splanchnic nerves, which contain preganglionic sympathetic nerves that originated from the thoracic spinal cord. The adrenal medulla has two separate populations of chromaffin cells, adrenaline-containing cells (A-cells) and noradrenaline-containing cells (NA-cells),(More)
We previously demonstrated that colony stimulating factor (CSF)-producing cell lines co-produce interleukin-1 (IL-1) and IL-6 in addition to CSFs. In the present study, we examined the role of IL-1 production in three human tumour cell lines producing granulocyte (G)-CSF, IL-1 and IL-6. Addition of anti-human IL-1 alpha antiserum to the culture caused a(More)
Previously we reported the cholinergic M2 muscarinic receptor-mediated inhibition of noradrenaline release from the rat stomach (K. Yokotani, Y. Osumi. J Pharmacol Exp Ther. 1993;264:54-60). In the present study, we investigated the role of K+ channels in oxotremorine (a muscarinic receptor agonist)-induced inhibition of noradrenaline release using(More)
