BACKGROUND The neurochemical status and hyperactivity of mice lacking functional substance P-preferring NK1 receptors (NK1R-/-) resemble abnormalities in Attention Deficit Hyperactivity Disorder (ADHD). Here we tested whether NK1R-/- mice express other core features of ADHD (impulsivity and inattentiveness) and, if so, whether they are diminished by(More)
Genetically-altered mice, lacking functional NK1 receptors (NK1R-/-), express abnormal behaviours that are prominent in Attention Deficit Hyperactivity Disorder: namely, inattentiveness and impulsivity (indicated by their greater % omissions and premature responses in the 5-Choice Serial Reaction-Time Task (5-CSRTT) and locomotor hyperactivity. We(More)
Mice with functional ablation of the substance P-preferring receptor gene ('Nk1r' in mice ('NK1R-/-'), 'TACR1' in humans) display deficits in cognitive performance that resemble those seen in patients with Attention Deficit Hyperactivity Disorder (ADHD): namely, inattentiveness, impulsivity and perseveration. A recent report suggested that the L-type Ca(v)(More)
Mice lacking functional neurokinin-1 receptors (NK1R-/-) display behavioural abnormalities resembling attention deficit hyperactivity disorder (ADHD): locomotor hyperactivity, impulsivity and inattentiveness. The preferred ligand for NK1R, substance P, is metabolised by angiotensin converting enzyme (ACE), which forms part of the brain renin angiotensin(More)
The effect of clonidine, naphazoline and xylometazoline on analgesia induced by morphine, codeine, fentanyl and pentazocine, and on cataleptic effect of morphine, codine and fentanyl was studied in rats. The biochemical assays on the influence of four analgesics on the brain concentration and turnover of noradrenaline (NA) were also performed. It was found(More)
In this paper we present the pumping methods for lasers based on double-clad fiber working in ring or linear configuration. We perform different configurations of pumping fiber couplers to pump double-clad fiber lasers. We also show the laser output signals obtained with the use of the discussed fiber laser pumping coupler
