Catalepsy and changes in striatal and limbic dopamine metabolism were investigated in mice after oral administration of aripiprazole, haloperidol, and risperidone. Catalepsy duration decreased with chronic (21 day) aripiprazole compared with acute (single dose) treatment across a wide dose range, whereas catalepsy duration persisted with chronic haloperidol(More)
Previously reported methods of liposome-mediated direct in vivo gene transfer have been inefficient, especially when performed with highly differentiated, quiescent cells of the adult mammalian central nervous system (CNS). We have therefore improved these procedures based upon a novel concept. Following continuous injection of plasmid DNA-cationic liposome(More)
Studies have suggested that the restorative effects of adrenal medullary chromaffin cell grafts in animal models of Parkinson's disease may be related to trophic factors contained within the chromaffin cells. Basic fibroblast growth factor (bFGF) is present in chromaffin cells and has been shown to exert trophic effects on dopaminergic neurons in vitro.(More)
A 58-year-old male suffered a massive intratumoral hemorrhage after placement of a ventriculoperitoneal shunt before treatment for pineocytoma. At admission, he complained of headache, urinary incontinence, gait disturbance, and recent memory disturbance. His neurological examination revealed impaired memory and papilledema from hydrocephalus. Two days(More)
UNLABELLED Aims/Introduction:  To evaluate the efficacy and safety of the glucagon-like peptide-1 receptor agonist, exenatide, in Japanese patients with type 2 diabetes mellitus suboptimally controlled despite therapeutic doses of a sulfonylurea alone or combined with a biguanide or thiazolidinedione. MATERIALS AND METHODS   Patients were randomized to a(More)
Accumulation of nerve growth factor (NGF) has been reported to occur at the distal stump of pretransected peripheral nerve. We performed adrenal medullary grafts or cografts of adrenal medulla and distal stump of pretransected peripheral nerve into the striatum of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated young or aging mice. We(More)
UNLABELLED Aims/Introduction:  We assessed the long-term (52 weeks) safety and efficacy of exenatide b.i.d. in Japanese patients with type 2 diabetes and suboptimal glycemic control. MATERIALS AND METHODS   Participants completing a 24-week randomized controlled trial of exenatide (5 μg, 10 μg or placebo b.i.d.) were invited to continue in a 28-week(More)
Pretransected peripheral nerve has been demonstrated to enhance the survival of cografted adrenal medullary chromaffin cells and the recovery of host dopaminergic (DA) systems in animal models of Parkinson's disease. In the present study, we examined the effect of donor age on survival of cografted chromaffin cells. Adrenal medulla and pretransected(More)
AIMS/INTRODUCTION Our primary objective was to assess changes in quality of life (QOL) associated with changes in insulin regimen in patients with type 2 diabetes mellitus. Secondary objectives were to assess the reasons for and patterns of changes in insulin regimen, and the effects on glycemic control. MATERIALS AND METHODS This 12-week, observational(More)
AIMS/INTRODUCTION An initial 26-week, randomized, open-label study compared the efficacy and safety of exenatide 10 mcg twice daily with exenatide 2 mg once weekly in Asian patients with type 2 diabetes who experienced inadequate glycemic control with oral antidiabetes medications. The aim of this study was to evaluate the safety of exenatide once weekly in(More)
