Samuels E, Szabadi E
Curr Neuropharmacol
. 2009 Jun;
6(3):254-85.
PMID: 19506724
The locus coeruleus (LC), the major noradrenergic nucleus of the brain, gives rise to fibres innervating most structures of the neuraxis. Recent advances in neuroscience have helped to unravel the...

Curr Neuropharmacol
. 2009 Jun;
6(3):235-53.
PMID: 19506723
The locus coeruleus (LC) is the major noradrenergic nucleus of the brain, giving rise to fibres innervating extensive areas throughout the neuraxis. Recent advances in neuroscience have resulted in the...

Hou R, Samuels E, LANGLEY R, Szabadi E, Bradshaw C
Psychopharmacology (Berl)
. 2007 Jul;
195(1):41-59.
PMID: 17659380
Rationale: There is a close relationship between arousal and pupil diameter, decrease in the level of arousal being accompanied by constriction of the pupil (miosis), probably reflecting the attenuation of...

Psychopharmacology (Berl)
. 2006 Jun;
187(4):498-510.
PMID: 16802163
Rationale: In a previous study in healthy volunteers, the anti-Parkinsonian drug pramipexole caused sedation and pupil dilatation, consistent with the stimulation of inhibitory D(2)/D(3) autoreceptors on the ventral tegmental area...

J Psychopharmacol
. 2006 Mar;
21(1):93-101.
PMID: 16533870
Classical fear conditioning involves pairing a neutral conditional stimulus (CS) with an aversive unconditional stimulus (US). Subsequent presentation of the CS alone induces fear responses. Acquisition of conditioned fear is...

J Psychopharmacol
. 2006 Jan;
20(6):756-70.
PMID: 16401653
The noradrenergic locus coeruleus is a major wakefulness-promoting nucleus of the brain, which is also involved in the regulation of autonomic and endocrine functions. The activity of the locus coeruleus...

Psychopharmacology (Berl)
. 2005 Nov;
184(1):95-106.
PMID: 16308726
Rationale: Patients suffering from Alzheimer's disease (AD) may show increased sensitivity to tropicamide, a muscarinic cholinoceptor antagonist. AD is associated with a severe loss of noradrenergic neurones in the locus...

Samuels E, Harrower T, Kahlon S, Oulton M, Macdonald J, Siauw C, et al.
Pediatr Pulmonol
. 1999 Mar;
27(2):95-103.
PMID: 10088932
The fetal lung secretes significant quantities of surfactant during late gestation to prepare for initiation of respiration at birth. However, the mechanism by which this occurs has not been determined....

Samuels E, Scott J
Life Sci
. 1995 Jan;
57(17):1557-68.
PMID: 7564903
Evidence indicates that Ca(+2)-phosphatidylserine-dependent protein kinase C (PKC) is involved in regulation of surfactant secretion. This study was done to examine PKC activity in lung as surfactant synthesis and secretion...

Samuels E, Scott J
Life Sci
. 1994 Jan;
55(14):1129-37.
PMID: 8090054
Pulmonary surfactant prevents lung collapse at minimal alveolar diameter. Since surfactant acts extracellularly, secretion is vitally important in regulating the alveolar surfactant levels. Studies with phorbol esters which stimulate protein...
