On drinkometers: Problems and an inexpensive photocell solution
(Elsevier, 1971-12)
Electronic contact switches may interfere with measurements of taste discrimination and also the ability to utilize physiological recording or stimulation techniques simultaneously. An inexpensive and simply constructed ...
The effects of thyroidectomy on the wheel running activity of female rats
(Elsevier, 1970-11)
The wheel running activity of female rats was observed prior to and following thyroidectomy. Thyroidectomy significantly reduced overall activity and increased the interval between activity peaks; thyroid feeding corrected ...
The effects of four days of continuous striatal microdialysis on indices of dopamine and serotonin neurotransmission in rats
(Elsevier, 1991-12)
The effects of 4 days of continuous microdialysis with a small-diameter concentric-style probe on indices of striatal dopamine (DA) and serotonin neurotransmission were assessed. It was found that over 4 days of dialysis, ...
Intracellular calcium and hormone release from nerve endings of the neurohypophysis in the presence of opioid agonists and antagonists
(Springer-Verlag, 1992-09)
Rat neural lobes and isolated nerve terminals from the neurohypophysis were stimulated in the presence of different opioid agonists and antagonists. The secretion of arginine vasopressin and oxytocin and rise in cytoplasmic ...

Bereavement is a potent and highly prevalent stressor among service members and veterans. However, the psychological consequences of bereavement, including complicated grief (CG), have been minimally examined. Loss was ...
Nerve growth factor increases choline acetyltransferase activity in developing basal forebrain neurons
(Elsevier, 1986-07)
Nerve growth factor (NGF) is a neuronotrophic protein. Its effects on developing peripheral sensory and sympathetic neurons have been extensively characterized, but it is not clear whether NGF plays a role during the ...
Effects of previous curare-immobilization on Pavlovian conditioned heart decelerations in the curarized rat
(Elsevier, 1975-03)
Recent evidence indicates that mechanisms other than the vagal-blocking properties of d-tubocurarine chloride (dTC) or inadequate respiration may account for the reports of invariant heart rate (HR) in curarized rats. Two ...
Gene expression of the insulin-like growth factors and their receptors in cultured human retinal pigment epithelial cells
(Elsevier, 1992-01)
Insulin-like growth factors I and II (IGF I and II) are polypeptides with both growth-promoting and insulin-like metabolic effects16,27. Immunoreactive IGF I is present in the retina14 and both IGF I and II are present in ...
Dynamic posture analysis of Spacelab-1 crew members

Dynamic posture testing was conducted on the science crew of the Spacelab-1 mission on a single axis linear motion platform. Tests took place in pre- and post-flight sessions lasting approximately 20 min each. The pre-flight ...
Contamination of commercially available quisqualic acid by glutamate-like and aspartate-like substances
(Elsevier, 1989-03)
Six different batches of the glutamic acid analogue quisqualic acid were analyzed with high-pressure liquid chromatography (HPLC). All batches examined showed contaminant peaks. Different batches had different contaminant ...
