\n\nData Sources: PubMed was searched for trials published in English LIP to January 2008 evaluating modafinil’s effects on fatigue, negative symptoms,

and cognition in schizophrenia with combinations of the following terms: schizophrenia, modafinil, cognition, negative symptoms, and fatigue.\n\nStudy Selection: Six trials were identified: 2 randomized, prospective, double-blind placebo-controlled trials; 3 randomized, prospective. double-blind placebo-controlled crossover trials and 1 open-label pilot study. Case series and case reports were excluded in the data analysis. except to identify potential adverse reactions to modafinil.\n\nData Extraction: Studies were examined for number of subjects,

trial duration, design, dosing, LDC000067 and outcomes with respect to sedation, negative symptoms, cognitive function, and tolerability.\n\nResults: One of 4 reviewed studies found a significant effect of modafinil as an alerting agent for anti psychotic-induced fatigue and sedation. Neither of 2 reviewed Studies found modafinil to improve negative symptoms of schizophrenia. Three of 6 reviewed studies showed that modafinil may improve short-term memory, attention, and the ability to shift mental sets. Two neuroimaging studies identified functional correlates in areas associated NCT-501 with working memory functions. The main adverse effect was found to be it small risk of psychosis exacerbation, which was seen in 5 of 83 patients (6.0%) in the active treatment groups as compared to 2 of 70 patients (2.9%) in the placebo groups.\n\nConclusions: While the available data suggest that modafinil

is generally well tolerated and may have some efficacy in the treatment of antipsychotic-induced sedation and cognitive domains. the small sample sizes, contradictory results,”
“Copper nanoparticles (Cu-NPs) were incorporated into chitosan hydrogel to form a film on the surface of a glassy carbon electrode (GCE) leading to a sensing element for D-arabinitol with excellent oxidative HM781-36B in vivo catalytic activity. The electrochemical response to D-arabinitol was studied by cyclic voltammetry and differential pulse voltammetry. Operational parameters affecting the response were examined and optimized, and a simple and sensitive method was established for the determination of D-arabinitol. Response is linear in the concentration range from 10 mu mol center dot L(-1) to 10 mmol center dot L(-1), and the limit of detection is 1.0 mu mol center dot L(-1). The method may be combined with separation techniques in order to analyze for the ratio of D- and L-arabinitol which is a diagnostic marker for candidiasis.
