Discordant changes in plasma ACTH and [beta]-lipotropin/[beta]-endorphin levels in Clshing's disease patients with depression
(Elsevier, 1992-11)
Cushing's Disease is often associated with a depressive syndrome, with mood, vegetative, and cognitive abnormalities of variable severity. In 11 patients with (pituitary ACTH-dependent) Cushing's disease (10 women, 1 man), ...
The effects of methallibure on conspecific visual reinforcement, social display frequency, and spawning in the Paradise Fish, Macropodus opercularis (L.) Belontiidae
(Elsevier, 1976-07)
Pretrial intramuscular administration of the antigonadotropin, methallibure suppressed operant responding for conspecific visual stimulation. Four administrations of the drug during an 11 day period did not noticeably ...
Movement-related phasic muscle activation
(Springer-Verlag, 1994-01)
To test the hypothesis that phasic muscle activation is related to the acceleration-deceleration characteristics of the resulting movement, we examined the relation between the duration of the acceleratory phase of a variety ...
Deafness-related decreases in glycine-immunoreactive labeling in the rat cochlear nucleus
(Wiley Subscription Services, Inc., A Wiley Company, 2005-07-01)
There is increasing evidence of activity-related plasticity in auditory pathways. The present study examined the effects of decreased activity on immunolocalization of the inhibitory neurotransmitter glycine in the cochlear ...
The influence of estrogen on nigrostriatal dopamine activity : Behavioral and neurochemical evidence for both pre- and postsynaptic components
(Elsevier, 1986-01)
The results of 3 experiments examining the influence of estrogen on the nigrostriatal dopamine (DA) system are reported. In two experiments the influence of hormonal manipulations on amphetamine (AMPH)-induced rotational ...
Rac/Rho pathway regulates actin depolymerization induced by aminoglycoside antibiotics
(Wiley Subscription Services, Inc., A Wiley Company, 2006)
Stress stimuli can lead to remodeling of the actin cytoskeleton and subsequent alteration of cell adhesion and permeation as well as cell functions and cell fate. We investigated redox-dependent Rho GTPase-linked pathways ...
Morphine inhibits cortisol and stimulates prolactin secretion in man
(Elsevier, 1984)
The role of opioids in endocrine regulation has been the subject of numerous studies. Surprisingly, however, the acute endocrine effects of morphine on basal hormonal levels in man have not been adequately documented. We ...
Use of osmium tetroxide-potassium ferricyanide in reconstructing cells from serial ultrathin sections
(Elsevier, 1987-05)
We describe a technique, modified from Langford and Coggeshall [Anat. Rec., 197 (1980) 297-303; J. Comp. Neurol., 203 (1981) 745-750], for enhancing membrane contrast and defining cellular boundaries, that is useful for ...
A double-blind, placebo-controlled study of the effect of imipramine on TRH-induced urinary urgency in healthy men
(Elsevier, 1992)
We studied the effect of imipramine (IMI) on thyroid releasing hormone (TRH)-induced urinary urgency as a way of investigating the mechanism of the beneficial effect of IMI on enuresis. In a double-blind study, 12 normal, ...
Effect of centrally administered interleukin-1 and endotoxin on food intake of fasted rats
(Elsevier, 1986)
We have previously shown that interleukin-1 (IL-1), a polypeptide known to mediate many aspects of the acute phase response to infection, suppresses food intake when injected intraperitoneally into fasted rats. IL-1 acts ...
