The effects of both noradrenaline and CGP12177, mediated through human beta(1)-adrenoceptors, are reduced by PDE3 in human atrium but PDE4 in CHO cells

open access: yes, 2007
(-)-Noradrenaline and (-)-CGP12177 activate beta(1)-adrenoceptors through a high (H)- and low-affinity (L) site, respectively. The positive inotropic effects of (-)-noradrenaline are blunted by phosphodiesterase4 (PDE4) but not PDE3, while both PDE ...

Early Paradoxical Increase of Dopamine: A Neurochemical Study of Olfactory Bulb in Asymptomatic and Symptomatic MPTP Treated Monkeys

open access: yesFrontiers in Neuroanatomy, 2017
Parkinson’s disease (PD) is a neurodegenerative disease with both motor and non-motor manifestations. Hyposmia is one of the early non-motor symptoms, which can precede motor symptoms by several years.

Bradykinin and noradrenaline preconditioning influences level of antioxidant enzymes SOD, CuZn-SOD, Mn-SOD and catalase in the white matter of spinal cord in rabbits after ischemia/reperfusion

open access: yesEuropean Journal of Histochemistry, 2019
The aim of present work is to assess the effects of bradykinin (Br) or noradrenaline (Nor) preconditioning to the levels of antioxidant enzymes: superoxide dismutase (SOD), copper, zinc superoxide dismutase (CuZn-SOD), manganese superoxide dismutase (Mn ...

SYMPATHOADRENERGIC MODULATION OF HEMATOPOIESIS: A REVIEW OF AVAILABLE EVIDENCE AND OF THERAPEUTIC PERSPECTIVES

open access: yesFrontiers in Cellular Neuroscience, 2015
Innervation of the bone marrow (BM) has been described more than one century ago, however the first in vivo evidence that sympathoadrenergic fibers have a role in hematopoiesis dates back to less than 25 years ago.

Increased Noradrenaline as an Additional Cerebrospinal Fluid Biomarker in PSP-Like Parkinsonism

open access: yesFrontiers in Aging Neuroscience, 2020
Academic centers utilize sequential clinical and neuroimaging assessments, including morphometric ratios, to obtain an unequivocal diagnosis of the non-synucleinopathic forms of Parkinsonism, such as progressive supranuclear palsy (PSP), however, a 1–2 ...

Depletion of noradrenaline inhibits electrically-evoked pain in the skin of the human forearm

open access: yes, 2008
Guanethidine displaces noradrenaline from sympathetic varicosities, and blocks sympathetic noradrenergic neurotransmission by inhibiting the release of noradrenaline from depleted neural stores. The aim of this study was to determine whether depletion of

Noradrenergic and cholinergic modulation of olfactory bulb sensory processing

open access: yesFrontiers in Behavioral Neuroscience, 2012
Neuromodulation in sensory perception serves important functions such as regulation of signal to noise ratio, attention, and modulation of learning and memory.

Investigation of a role for noradrenaline in the neurochemical and behavioural effects of an established and putative target for antianxiety/antidepressant drugs: a microdialysis and behavioural study in rats and NK1 receptor knockout mice.

open access: yes, 2005
The precise neurochemical effects of antidepressants that underlie their efficacy remain unclear. Many antidepressants modulate noradrenaline transmission in vivo.

Comparison of the Effects of Octopamine and Noradrenaline on Feeding and Sleep-like Behaviour in Fasted Chicks

open access: yesThe Journal of Poultry Science, 2002
Octopamine, an important neurotransmitter in invertebrates, has noted several similarities with noradrenaline (NA) in mammals. To compare the effect of octopamine and NA in the central nervous system, food intake and categorized postures of fasted chicks

Repeated cycles of electrical stimulation decrease vasoconstriction and axon-reflex vasodilation to noradrenaline in the human forearm

open access: yes, 2007
To investigate whether desensitization to the vasomotor effects of noradrenaline is a specific effect of electrical stimulation. Three sites on the forearm of 10 healthy volunteers were stimulated with 0.2 mA direct current for 2 min twice daily for 10 ...
