Repeated treatment in ontogeny with the dopamine (DA) D(2)/D(3) receptor agonist quinpirole is associated with enhanced quinpirole-induced yawning and other behaviors such as vacuous chewing, vertical jumping, and antinociception. To determine if the reputedly DA D(3) agonist (+/-)-2-(dipropylamino)-7-hydroxy-1,2,3, 4-tetrahydronaphthalene (7-OH-DPAT) would(More)
The intracellular second messenger nitric oxide (NO) is implicated in a variety of physiological functions, including release and uptake of dopamine (DA). In the described study, in vivo microdialysis and differential pulse voltammetric techniques were used to determine the involvement of NO in release of DA and its metabolites (dihydroxyphenylalanine,(More)
In the neonatally 6-hydroxydopamine (6-OHDA)-lesioned rat hyperlocomotor activity, first described in the 1970s, was subsequently found to be increased by an additional lesion with 5,7-dihydroxytryptamine (5,7-DHT) (i.c.v.) in adulthood. The latter animal model (i.e., 134 microg 6-OHDA at 3 d postbirth plus 71 microg 5,7-DHT at 10 weeks; desipramine(More)
OBJECTIVES The pathogenesis of anorexia nervosa (AN) remains still unclear. It has been reported that neuropeptides may play a role in the control of appetite and hormone release contributing to hormonal disturbances in AN. However the question if neuropeptide alterations are consequence or cause of malnutrition is still unresolved. METHODS Serum leptin,(More)
OBJECTIVES Very little is known about the role of adipokines in atopic asthma in children. Studies about the potential role of novel proinflammatory adiopcytokine - visfatin are lacking. DESIGN AND SETTING In this cross-sectional study serum visfatin (VISF) levels were measured in 89 asthmatic out-patients (61 boys and 28 girls aged 7.0-17.0 years) and in(More)
OBJECTIVE Childhood autism is a neurodevelopmental disorder characterized by impairments in social interactions, verbal and non-verbal communication and by a pattern of stereotypical behaviors and interests. The aim of this study was to estimate the dysmorphic facial features of children with autism and children with Asperger syndrome. METHODS The(More)
OBJECTIVES Thyroid, adrenal glands and gonadal hormones play a role in maintaining metabolic homeostasis of the body via the receptors located in the adipose tissue. The correlations between serum resistin (RES) and function of other hormonal axes in patients with AN have not been established, yet. Therefore, the aim of this study is: 1) assessment of(More)
Question 1. What is the final diagnosis? Hypoparathyroidism in childhood is predominantly due to congenital parathyroid agenesis or hypoplasia, associated with numerous conditions, the most common one being the Di George syndrome (approximately 70 % of children with isolated hypoparathyroidism) [1]. Rare conditions may include specific renal disturbances,(More)
A 14-year-old Caucasian girl with a history of primary hypoparathyroidism and unstable calcium and phosphorus levels and on ongoing treatment was admitted to the Department of Pediatric Nephrology because of the onset of nephrocalcinosis and difficulties achieving normocalcemia. Coexistence of hypoparathyroidism, oral candidiasis, dental enamel hypoplasia,(More)
OBJECTIVES Stimulation of some noradrenergic system receptors demonstrates a synergistic anti-nociceptive effect with the opioid system at the level of peripheral tissues, spinal cord, and supraspinal structures. Furthermore, opioids stimulate the noradrenergic descending pathways originating from the substantia nigra by presynaptic inhibition of the GABA(More)
