This study evaluated a model of attention that postulates several distinct component processes, each mediated by specific neural systems in the human frontal lobes. A series of reaction time (RT) tests (simple, choice, and prepare) examined the hypothesis that different attentional processes are related to distinct regions within the frontal lobes. These(More)
OBJECTIVES The aim of the present study was non-invasive evaluation of the cardiovascular system in asymptomatic young adult patients with juvenile localized scleroderma (JLS) and juvenile systemic sclerosis (JSS). METHODS A group of 34 consecutive children with scleroderma were prospectively observed in the study. The control group (CG) consisted of 20(More)
BACKGROUND Cyclosporine (CsA) is an immunosuppressive agent whose use is associated with adverse effects, including nephrotoxicity. There are reports indicating that some CsA metabolites may contribute to these effects. This study was aimed at evaluation of CsA metabolites and correlating them with kidney function. METHODS In 62 kidney transplant(More)
BACKGROUND 6-Mercaptopurine (6-MP) and its prodrug azathioprine (AZA) are used in many autoimmune diseases and after solid-organ transplantation. Their properties are mediated by active metabolites, 6-thioguanine nucleotides (6-TGN), and 6-methylmercaptopurine (6-MMP). The most common adverse effects are myelo- and hepato-toxicity. The aim of the study was(More)
BACKGROUND Tacrolimus (Tac) is one of the most commonly used immunosuppressive drugs after solid organ transplantation. Eight Tac metabolites have been described, but their clinical importance remains unclear. The aim of this study was quantification of the 2 major Tac metabolites, 13-O-demethyl (M-I) and 15-O-demethyl (M-III), in kidney transplant(More)
