Projection-neurons that send axons through the lumbar spinal cord of the chick embryo are not obviously distributed in a segmentally repetitive pattern
(Wiley Subscription Services, Inc., A Wiley Company, 1988-10)
Earlier studies have shown that the formation of the segmentally repetitive pattern of spinal nerves in avian embryos depends upon the segmental arrangement of the somites and does not reflect an intrinsic pattern of the ...
Expression of an engrailed -like gene during development of the early embryonic chick nervous system
(Wiley Subscription Services, Inc., A Wiley Company, 1988-10)
The engrailed gene has been identified in Drosophila as an important developmental gene involved in the control of segmentation. Here we describe the embryonic expression of a chicken gene, ChickEn (Darnell et al.: ...
Nervus terminalis innervation of the goldfish retina and behavioral visual sensitivity
(Elsevier, 1988-08-31)
The possibility that axon terminals of the nervus terminalis in the goldfish retina regulate visual sensitivity was examined psychophysically. Fish were classically conditioned to respond in darkness to a diffuse red light ...
Computer aided analysis for biosensing and screening
(Wiley Subscription Services, Inc., A Wiley Company, 1988-02-20)
Biosensors with animal and microbial cells immobilized close to the tip of a membrane electrode have been developed for chemical and drug testing. Our experimental results show that biosensors can be used for drug screening ...
Paradoxical effect of corticosteroids on pituitary ACTH/[beta]-endorphin release in stressed animals
(Elsevier, 1988)
We have previously demonstrated a number of changes in the anterior lobe proopiomelanocortin (POMC) system in chronically stressed rats. The purpose of the present experiments was to investigate whether chronically stressed ...
Monoclonal antibodies made to chick mesencephalic neural crest cells and to ciliary ganglion neurons identify a common antigen on the neurons and a neural crest subpopulation
(Wiley Subscription Services, Inc., A Wiley Company, 1988-10)
We previously reported the production of monoclonal antibodies (Mabs) that identified cell surface components of cultured chick and quail ciliary ganglion (CG) neurons and of a subpopulation of neural crest (NC) cells from ...
Effects of ethanol withdrawal on ethanol-reinforced responding in rhesus monkeys
(Elsevier, 1988-12)
Rhesus monkeys self-administered ethanol intravenously during daily, 3-h sessions. When ethanol-reinforced responding was stable and ethanol intake was in the range of 2.6-3.6 g/kg/3 h, physiological dependence to ethanol ...
A study of costs and behavioral outcomes of menstrual regulation services in Bangladesh
(Elsevier, 1988)
This paper reports the results of a program evaluation of menstrual regulation (MR) services provided by the Bangladesh Women's Health Coalition, a nongovernmental organization formed in response to a concern about the ...
Computer modeling of antibiotic fermentation with on-line product removal
(Wiley Subscription Services, Inc., A Wiley Company, 1988-07-20)
The fermentation of Streptomyces griseus for the production of cycloheximide is similar to other antibiotic fermentations in that product synthesis is subject to feedback regulation and the desired product is degraded ...
