The Atacama Large Millimeter/submillimeter Array (ALMA) serendipitously detected H$_2$O $J_{Ka, Kc} = 10_{2,9} - 9_{3,6}$ emission at 321 GHz in NGC 1052. This is the first submillimeter maser detection a radio galaxy and most luminous 321-GHz known to date with isotropic luminosity of 1090 $L_{\odot}$. line profile consists broad velocity component FWHM $= 208 \pm 12$ km s$^{-1}$ straddling sy...

Chemoreceptor discharges were recorded from the carotid sinus nerve of the cat in vivo, and their frequency was used as an index of receptor activity. The effects of dopamine on chemoreceptor activity were analyzed in normal and ischemic carotid bodies. Intra-arterial injections of dopamine (DA) induced various patterns of chemoreceptor responses; simple inhibition, inhibition followed by excit...

Growth of C-1300 neuroblastoma was markedly suppressed in mice chemically sympathectomized at birth with 6-hydroxydopamine. Growth of A-10 adenocarcinoma was also somewhat reduced. In newborn mice pretreated with nerve growth factor to induce sympathetic nervous system neuronal hypertrophy, neuronal maturation, and peripheral hyperinnervation, the growth of neuroblastoma was augmented.
