Journal ArticleDOI
Cysteamine-induced depletion of central somatostatin-like immunoactivity: effects on behavior, learning, memory and brain neurochemistry.
Vahram Haroutunian,Vahram Haroutunian,R. Mantin,G.A. Campbell,G.K. Tsuboyama,Kenneth L. Davis,Kenneth L. Davis +6 more
TL;DR: The results of this series of experiments suggest that somatostatin, in addition to its effects on hormonal regulation, may play an important role in behavior and passive avoidance learning and memory.
Journal ArticleDOI
Restoration of cholinomimetic activity by clonidine in cholinergic plus noradrenergic lesioned rats.
Vahram Haroutunian,Vahram Haroutunian,Philip D. Kanof,Philip D. Kanof,G.K. Tsuboyama,G.K. Tsuboyama,Kenneth L. Davis,Kenneth L. Davis +7 more
TL;DR: Results suggest that combined cholinergic/noradrenergic therapy may be of value in the treatment of some Alzheimer's disease patients.
Journal ArticleDOI
Animal models of Alzheimer's disease: behavior, pharmacology, transplants.
TL;DR: Intravenous physostigmine produced a significant improvement in patients' ability to recognize words and particularly to distinguish words they had never seen before from words previously presented, which proved all but impossible to assess due to concomitant adverse effects, particularly dysphoria.
Journal ArticleDOI
Agitation and postdexamethasone cortisol levels in Alzheimer's disease.
Brian A. Lawlor,G.K. Tsuboyama,Theresa M. Ryan,Richard C. Mohs,Bonnie M. Davis,Michael H. Davidson,S. Gabriel,Kenneth L. Davis +7 more
TL;DR: The clinical correlates of hypothalamic-pituitary-adrenal (HPA) functioning were examined in 29 patients with probable Alzheimer's disease and postdexamethasone cortisol levels were highly correlated with higher agitation scores but not with the degree of depressed mood or memory impairment.
Journal ArticleDOI
Highly Sensitive and Simple Method for Determination of Free 3-Methoxy-4-Hydroxyphenylglycol in Plasma by High-Performance Liquid Chromatography Using a Sep-Pak Alumina B Cartridge
TL;DR: In this article, a sample clean-up procedure for the determination of free 3methoxy-4-hydroxyphenylglycol (MHPG) in plasma was described.
