Primary preventive health care in children with heart disease
(Springer-Verlag, 1983-10)
In order to evaluate the preventive health care practices in children with heart disease, 499 families were surveyed in outpatient settings. Data were collected on 215 children with heart disease and 284 control children ...
Composition and origin of summertime air pollutants at Deep Creek Lake, Maryland
(Elsevier, 1989)
A 1 month intensive summertime field study conducted in rural western Maryland resulted in a comprehensive set of fine particle, gaseous and meteorological data. Sulfur in the assumed form of ammonium sulfate accounted for ...
Analysis of No-Difference Findings in Evaluation Research
(Sage Publications, 1989)
Conclusions of no difference are becoming increasingly important in evaluation research. We delineate three major uses of no-difference findings and analyze their meanings. (1) No-differ ence findings in randomized experiments ...
Polybrominated biphenyls in lactating Michigan women: Persistence in the population

Culturing spinal cord explants in a collagen gel
(Elsevier, 1984-08)
A new method for culturing spinal cord slices or explants is presented which entails the use of a commercially available purified collagen, Vitrogen. Vitrogen provides a stable three-dimensional matrix for culturing spinal ...
Calmodulin distribution in peripheral nerve: an EM immunocytochemical study
(Elsevier, 1988-12-20)
We used electron microscopic immunocytochemistry to study the distribution of calmodulin in rat sciatic nerve. Calmodulin immunoreactivity was found throughout the axoplasmic matrix, but particularly along microtubules. ...
A signal generator for testing extracellular recording amplifiers and probes
(Elsevier, 1988-10)
A portable signal generator that simulates the amplitude and frequency of neuronal signals for testing extracellular recording amplifiers is described. The signal generator is easy to construct and it is extremely useful ...
Further studies on a novel animal model of depression: Therapeutic effects of a tricyclic antidepressant
(Elsevier, 1981)
