A1 adenosine receptors from rat brain membranes were solubilized with the zwitterionic detergent 3-[3-( cholamidopropyl)dimeth ylammonio ]-1-propanesulfonate. The solubilized receptors retained all the characteristics of membrane-bound A1 adenosine receptors. A high and a low agonist affinity state for the radiolabelled agonist (R)-N'-eHJphenylisopropyladenosine((JH]PJA) with Kn values of 0.3 a...

The presence and activity of denitrifying bacteria as well as bacteria capable of reducing sulfate in 1 upland and 5 riparian soils of a mountain watershed in Wyoming were studied. Bacteria were enumerated from soil samples collected during summer along transects placed perpendicular to stream flow. Samples were taken at 3 depths within each plant community. Subsamples were frozen and later uti...

This study is concerned with the effects of having people older than 60 years of age participate as peers in the college classroom with college-age students. We were particularly interested in changes in attitudes of the younger participants toward their own aging, older people, and intergenerational classes, and in changes in attitudes of the older students toward intergenerational classes, yo...

The reproductive biology of copepods plays a key role in seasonal population oscillations and therefore determines, among other things, annual production (Kiørboe et al., 1988; Fransz et al., 1989; Ianora and Buttino, 1990; Ianora et al., 1992; Halsband and Hirche, 2001). Reproduction is affected by various environmental factors, basically by temperature and food availability (Dagg, 1978; Landr...

Development of effective treatment programs for childhood acute lymphoblastie leukemia (ALL) has led to marked improvement of prognosis. The proportion of patients remaining in first remission for at least 5 years is generally estimated to be in the range of 50% once remission is achieved (Frei and Sallan 1978; Riehm etal.1980;Robisonetal.1980). Since remission rates have been shown to be 90%-9...
