It has nearly been a decade since the introduction of the vaccine against human papillomavirus (HPV), yet vaccination rates in the United States have remained suboptimal, particularly among Hispanics. Culturally and linguistically relevant health education tools targeting Hispanics are needed to increase the current rate of HPV vaccination. This article(More)
Preconditioning describes a variety of treatments that induce neurons to become more resistant to a subsequent ischemic insult. How preconditioned neurons adapt to subsequent ischemic stress is not fully understood, but is likely to involve multiple protective mechanisms. We hypothesized hypoxic preconditioning induces protection by a coordinated(More)
The in vitro and in vivo effects of estrogen and progesterone on muscarinic and beta-adrenergic receptors of cardiac tissue were studied in ovariectomized (OVX) rats. The binding assay for muscarinic receptors was performed under a nonequilibrium condition; whereas the binding assay for beta-adrenergic receptors, under an equilibrium condition. Estrogenic(More)
Extracellular action potentials were recorded from 691 neurons in the ventromedial hypothalamus (VMH) of urethane anesthetized female rats under acute and chronic sham-operated and hyperprolactinemic conditions. Hyperprolactinemia was produced by transplanting pituitaries under the kidney capsules. Neuronal excitability was recorded and analyzed during(More)
The effect of iontophoretically-applied prolactin, dopamine, LHRH and LHRH-antagonist analog on the electrical activity of neurons (n = 192) located in the ventromedial nucleus of the hypothalamus (VMH) was studied in untreated and hormone-treated ovariectomized female rats (n = 63). The spontaneous electrical activity of VMH neurons was unaffected by the(More)
The spontaneous firing rate of midbrain central gray (MCG) neurons and the effect of iontophoretically applied prolactin and luteinizing hormone releasing hormone (LH-RH) on the electrical activity of these neurons was studied in untreated and estrogen-progesterone-treated ovariectomized female rats. The spontaneous firing rate of MCG neurons as well as the(More)
Neurons of the ventromedial hypothalamus (VMH) in female rats were electrophysiologically recorded via multibarrelled glass micropipettes and tested for responsiveness to vaginocervical stimulation as well as to a variety of other peripheral stimuli. A small percentage of VMH neurons were found to be specifically responsive to vaginocervical stimulation(More)
A total of fifty steroidal compounds were tested for their inhibition on the binding of muscarinic receptor antagonist, [3H]quinuclidinyl benzilate ([3H](-)QNB), to the hypothalamic membranes prepared from male rats. Among the compounds tested, the active structures (with IC50 values less than or equal to 100 microM in parentheses) are: progesterone (40), 5(More)
