Serotonin is a major neurotransmitter and affects various functions both in the brain and in the rest of the body. It has been demonstrated that altered serotinergic function is implicated in various psychiatric disorders including depression and schizophrenia. Serotonin has also been implicated along with dopamine in attention deficit-hyperkinetic disorder(More)
BACKGROUND Very preterm newborn infants often need cardiovascular support. More knowledge about myocardial function and factors that influence the immature myocardium may be helpful for optimising cardiovascular support in these infants. OBJECTIVE Serial assessment of global myocardial function by means of colour tissue Doppler imaging (cTDI) in very and(More)
Adenosine stress echocardiography was performed in nine patients (58 (+/-3) years, eight women) with documented microvascular angina. Global ventricular function was assessed by Tc(99m) blood pool imaging and Doppler, whereas longitudinal ventricular function was assessed by simultaneous tissue Doppler echocardiography of the lateral mitral annulus.(More)
Background and aims: Tissue Doppler imaging (TDI) is a new tool for measuring myocardial function. The feasibility of this method has not yet been validated in very preterm infants.The aims of this study was to explore the feasibility of measuring myocardial function by TDI in newborn, very preterm infants.Methods: Twenty-eight infants (median (range)(More)
BACKGROUND Superior vena cava (SVC) flow has become a surrogate measure of systemic blood flow in neonates. OBJECTIVE The aim of this study was to establish normal SVC flow values in healthy term infants the first 3 days of life and to evaluate the feasibility and reliability of the off-line analyses. DESIGN Doppler echocardiography of SVC flow was(More)
BACKGROUND/AIM Loss of periodontal support and related tooth loss is a common finding among HIV+ patients. The etiology of this destruction may be an increase in the levels of pro-inflammatory cytokines and subsequent increase in periodontal disease activity. The purpose of this study was to investigate the associations between gingival crevicular fluid(More)
Background and aims: Cardiovascular monitoring of the preterm is challenging. Blood pressure (BP) is an indirect measure of cardiovascular function.Superior vena cava (SVC) flow has become a surrogate measure of systemic flow. Tissue Doppler imaging (TDI) is a new tool for measuring myocardial function.The aim of this study was to explore the relation of(More)
