Tail pinch induced stress-arousal facilitates brain stimulation reward
(Elsevier, 1979-01)
Adult male Sprague Dawley rats with chronic access to self stimulation were subjected to handling, tail pinch, or left undisturbed. Tail pinch increased responding for positive reinforcement while the other conditions did ...
Non-parametric estimation of gap time survival functions for ordered multivariate failure time data
(John Wiley & Sons, Ltd., 2004-06-30)
Times between sequentially ordered events (gap times) are often of interest in biomedical studies. For example, in a cancer study, the gap times from incidence-to-remission and remission-to-recurrence may be examined. Such ...
Electron microscopic demonstration of horseradish peroxidase-tetramethylbenzidine reaction product as a method for identifying sensory nerve fibers in the rat tooth pulp
(Elsevier, 1983-11-11)
The purpose of the present investigation was to determine if the horseradish peroxidase could be used as a method for labeling sensory nerve fibers (specifically, tooth pulp afferents) for detailed ultrastructural analyses. ...
Mating behavior induces selective expression of Fos protein within the chemosensory pathways of the male Syrian hamster brain
(Elsevier, 1992-08-31)
The effect of mating behavior on the expression of Fos protein was analyzed within the chemosensory pathways of the male Syrian hamster brain. Following a single mating test, the number of Fos-immunoreactive (Fos-ir) neurons ...
High School Students' Critical Evaluation of Scientific Resources on the World Wide Web
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-06)
This research explores a new web-based curriculum idea, that of having students write and publish critical web “reviews” of scientific resources as a means of both practicing critical evaluation of web resources, and of ...
Unilateral substantia nigra lesions and schedule-induced polydipsia
(Elsevier, 1986)
The present experiment investigated the effects of unilateral 6-hydroxydopamine lesions of the substantia nigra (SN) on schedule-induced polydipsia (SIP). Lesions were made in either the "dominant" or "non-dominant" ...
The relationship between the macro- and microclimate
(Elsevier, 1965-04)
A search of the literature has yielded a very small number of papers dealing with quantitative relationships between the macro- and microclimate. Such relationships would be of great value in view of the difficulty in ...
Animal models and human depressive disorders
(Elsevier, 1981)
Clinical depressive disorders are complex in presentation, dissimilar in origins and course, and often pleomorphic in character. An adequate understanding of their origins, biological substrates, and amenability to established ...
A shared random effects model for censored medical costs and mortality
(John Wiley & Sons, Ltd., 2006)
In this paper, we propose a model for medical costs recorded at regular time intervals, e.g. every month, as repeated measures in the presence of a terminating event, such as death. Prior models have related monthly medical ...
Chronic drug infusion into the scala tympani of the guinea pig cochlea
(Elsevier, 1992)
This research describes a unique, effective and inexpensive delivery system to provide discrete quantities of drugs on a chronic basis to the inner ear. The amount of the drug administered and specific timing of each ...
