All known actions of cAMP in the brain require cAMP-dependent protein kinase (cAMPdPK), which consists of regulatory (R) and catalytic (C) subunits (R2C2). Using homologous rat cDNAs for all known cAMPdPK subunit isoforms found in the brain (RI alpha

A rat complementary DNA (cDNA) for the RI beta isoform of type I cyclic adenosine monophosphate (cAMP)-dependent protein kinase regulatory subunit was cloned and sequenced and was found to contain the entire protein coding and 3'-untranslated regions

A number of reflective wavefront correctors used in adaptive optics are based on the use of piezoelectric effect, either in piston, tip/tilt or curvature devices. The relation between the voltage applied to drive these devices and the mechanical resp

Pinealectomy in the female golden Syrian hamster is not always completely effective in preventing the suppressive effects of long-term light deprivation due to blinding on pituitary prolactin (PRL) cell activity. We examined this curious phenomenon b

The purpose of this study was to observe the molecular dynamics of pituitary prolactin (PRL) gene expression during the estrous cycle of the Golden Syrian hamster. PRL messenger ribonucleic acid (mRNA) levels, PRL synthesis (3H-PRL in the incubation

In this work the Preisach classical and nonlinear models are used to model the hysteretic response of a piezoceramic deformable mirror for use in adaptive optics. Experimental results show that both models predict the mirror behavior to within 5% roo

Pituitary prolactin (PRL) cell activity (i.e. PRL messenger ribonucleic acid [mRNA] levels, PRL synthesis, and radioimmunoassayable [RIA]-PRL), and serum RIA-PRL were measured in female golden Syrian hamsters that were (1) light-deprived and then ova

Light deprivation by blinding or exposure to short photoperiod results in depressed prolactin (PRL) cell activity and gonadal regression in the male Syrian hamster after at least 42-56 days of treatment, and both of these events can be prevented if p
