Serotonin 1A (5-HT1A) receptors are distributed throughout the brain with their highest concentrations in the frontal cortex, subthalamic nucleus and entopeduncular nucleus as well as the dorsal and median raphe nucleus. There is growing evidence that 5-HT1A receptor agonists have an antidepressant effect in individuals with major depressive disorders.(More)
At a muscle length L0 (just taut), isometric tension and ATPase activity were measured at constant levels of various Ca2+ activations in muscle fibres (2-3 mm long and 34-66 microns in diameter) isolated from temporal, masseter and digastric (anterior belly) muscles. The isometric tension increased in a sigmoid fashion with increasing Ca2+ concentration(More)
Oxaliplatin-induced peripheral neurotoxicity (OPN) is commonly associated with peripheral hypersensitivity to cold sensations (CS) but the mechanism is unknown. We hypothesized that the transient receptor potential melastatin 8 (TRPM8), a putative cold and menthol receptor, contributes to oxaliplatin cold hypersensitivity. To determine whether the TRPM8 is(More)
We examined the effects of the angiotensin converting enzyme (ACE) inhibitors captopril, enalaprilat, quinapril, and trandolapril, and their active metabolites quinaprilat and trandolaprilat, on hemolysis induced by lysophosphatidylcholine (LPC) in human erythrocytes. LPC induced hemolysis at the concentrations above the critical micelle concentration (4(More)
In the treatment of Parkinson's disease, potent disease-modifying drugs are still needed to halt progressive dopaminergic neurodegeneration. We have previously shown that meloxicam, an oxicam non-steroidal anti-inflammatory drug (NSAID), elicits a potent neuroprotective effect against 1-methyl-4-phenyl pyridinium (MPP(+))-induced toxicity in human(More)
Although a number of analytical methods for taxanes have been published, none of them are sufficiently suitable for use in a medical setting. In this study, we established an improved analytical HPLC/UV detection method using a Sep-Pak C18 cartridge for extraction and a semi-micro-borecolumn for separation. This method employed here reduced chromatographic(More)
PROBLEM Are cell adhesion molecules involved in the murine model of immunologically-mediated spontaneous abortion? METHOD OF STUDY Pregnant CBA/J female mice mated with DBA/2 male mice were injected with monoclonal antibodies (MAbs) to intercellular adhesion molecule-1 (ICAM-1) and leukocyte function-associate antigen-1 (LFA-1). On day 13 of gestation.(More)
In performing FOLFOX (infusional 5-FU/LV with oxaliplatin) for advanced colorectal cancer, neurotoxicity of oxaliplatin (L-OHP) is the serious dose limiting factor. On the other hand, goshajinkigan is recently considered as an effective agent for the neurotoxicity of taxanes in Japan. We have applied goshajinkigan (TJ 107) for a case of advanced colon(More)
Calcium and magnesium replacement is effective in reducing oxaliplatin-induced neurotoxicity. However, cetuximab treatment has been associated with severe hypomagnesaemia. Therefore, we retrospectively investigated whether cetuximab-induced hypomagnesaemia exacerbated oxaliplatin-induced neurotoxicity. Six patients with metastatic colorectal cancer who were(More)
In performing FOLFOX chemotherapy (infusional 5-FU/LV with oxaliplatin) for advanced colorectal cancer, the neurotoxicity of oxaliplatin (L-OHP) is the dose-limiting factor. A retrospective study of 25 consecutive patients, receiving modified FOLFOX6 (mFOLFOX6) for advanced colorectal cancer, was conducted. From March 2006 to February 2008, we investigated(More)
