8-Cyclopentyl-1,3-dipropylxanthine (PD 116,948) is a very potent, very A1-selective adenosine antagonist, with a K i of 0.46 nM in 3H-CHA binding to A1 receptors in rat whole brain membranes and 340 nM in 3H-NECA binding to A2 receptors in rat striatal membranes. Its 740-fold A1-selectivity is the highest reported for an adenosine antagonist. 3H-PD 116,948(More)
The male reproductive glands of the red-bellied tree squirrel, Callosciurus erythraeus, in the infantile, and prepubertal males, as well as sexually functional, degenerating and redeveloping adults were studied histologically. In the infant, testes are characterized with solid seminiferous tubules filled with primordial germ cells and Sertoli cells.(More)
Bacterial superantigens have potent in vivo effects. Respiratory viral infections are often associated with secondary bacterial infections, raising the likelihood of exposure to bacterial superantigens after the initiation of the anti-viral immune response. In this study, the general and V beta-specific effects of exposure to Staphylococcal enterotoxin B(More)
