Jacqueline M Ho et al.
Endocrinology, 155(8), 2845-2857 (2014-06-01)
Oxytocin (OT)-elicited hypophagia has been linked to neural activity in the nucleus of the solitary tract (NTS). Because plasma OT levels increase after a meal, we hypothesized that circulating OT acts at both peripheral and hindbrain OT receptors (OTRs) to

Anaphylactic shock is sometimes life-threatening, and it is accompanied by hepatic venoconstriction in animals, which, in part, accounts for anaphylactic hypotension. Roles of norepinephrine and α-adrenoceptor in anaphylaxis-induced hypotension and portal hypertension were investigated in anesthetized ovalbumin-sensitized Sprague-Dawley rats. The

Bioelectromagnetics, 42(6), 455-463 (2021-05-21)
Recent studies have revealed that rodents' physiological responses to low-intensity radiofrequency (RF) electromagnetic fields were similar to thermoregulatory responses to cold conditions. The primary autonomic response to cold exposure is peripheral vasoconstriction that allows rodents to reduce heat loss and maintain

Memory processes may be involved in the transition from drug lapses to relapse. This study explored the role of noradrenaline (NA) in reacquisition of place preference, an animal model of relapse that involves the updating of memories about drugs and

We examined the hypothesis that α(1)-adrenergic blockade would lead to an inability to correct initial orthostatic hypotension (IOH) and cerebral hypoperfusion, leading to symptoms of presyncope. Twelve normotensive humans (aged 25 ± 1 yr; means ± SE) attempted to complete

In the neonate forebrain, network formation is driven by the spontaneous synchronized activity of pyramidal cells and interneurons, consisting of bursts of electrical activity and intracellular Ca2+ oscillations. By employing ratiometric Na+ imaging in tissue slices obtained from animals at

Danshensu [3-(3,4-dihydroxyphenyl)-lactic acid], a phenylpropanoid compound isolated from Prunella vulgaris var. lilacina, is a well-known antioxidant. Although its antioxidant activity and cardioprotective effect have been reported, the pharmacological properties of danshensu in the central nervous system remain unclear. We investigated

Diurnal release of the orexin neuropeptides orexin-A (Ox-A, hypocretin-1) and orexin-B (Ox-B, hypocretin-2) stabilises arousal, regulates energy homeostasis and contributes to cognition and learning. However, whether cellular correlates of brain plasticity are regulated through orexins, and whether they do so

Adrenaline (epinephrine) is one of the prime messengers of the fight-or-flight response, favoring the activation of β-adrenergic receptors. Although general vasoconstriction to nonessential tissues is imperative, the vasodilatory effect of β-adrenergic receptor activation contends with this. We aimed to determine

Alcoholism, clinical and experimental research, 38(6), 1532-1539 (2014-06-04)
Evidence suggests that activation of the noradrenergic system may contribute to alcohol drinking in animals and humans. Our previous studies demonstrated that blocking α1 -adrenergic receptors with the antagonist, prazosin, decreased alcohol drinking in rats under various conditions. As noradrenergic

Understanding mouse thermal physiology informs the usefulness of mice as models of human disease. It is widely assumed that the mouse tail contributes greatly to heat loss (as it does in rat), but this has not been quantitated. We studied

The Journal of clinical investigation, 124(7), 3230-3240 (2014-06-18)
Autonomic sympathetic nerves innervate peripheral resistance arteries, thereby regulating vascular tone and controlling blood supply to organs. Despite the fundamental importance of blood flow control, how sympathetic arterial innervation develops remains largely unknown. Here, we identified the axon guidance cue

PloS one, 7(10), e46659-e46659 (2012-10-17)
Peripheral vascular disease in pre-diabetes may involve altered sympathetically-mediated vascular control. Thus, we investigated if pre-diabetes modifies baseline sympathetic Y(1)-receptor (Y(1)R) and α(1)-receptor (α(1)R) control of hindlimb blood flow (Q(fem)) and vascular conductance (VC). Q(fem) and VC were measured in

We have recently found that isolation-reared mice show hyperactivity during an encounter with an intruder. However, it is not known whether encounter-induced hyperactivity may model some aspects of psychiatric disorders. The present study examined the pharmacological profile of encounter-induced hyperactivity

The goal was to identify alpha-1-adrenergic receptor (AR) subtypes in human coronary arteries. The alpha1-ARs regulate human coronary blood flow. The alpha1-ARs exist as 3 molecular subtypes, alpha1A, alpha1B, and alpha1D, and the alpha1D subtype mediates coronary vasoconstriction in the
