Inflammation-derived oxidative stress is postulated to contribute to neuronal damage leading to poor clinical outcomes in Acute Ischemic Stroke (AIS). We aimed to investigate the association between serum levels of selected cytokines (IL-1β, IFN-γ, IL-4), and vitamin D in ischemic stroke progression, and their accuracy in predicting AIS prognosis, among Sri Lankans. We compared 60 AIS patients admitted in 4 phases post-stroke onset (<6 h; 6-24 h; 24-48 h; 48-96 h; n = 15/phase), with 15 age- and sex-matched controls.

Background: Transcranial direct current stimulation (tDCS) has been shown to enhance verbal productivity, but the finding and extent of enhancement vary across studies. Few attempts to replicate positive tDCS findings have been reported, suggesting the possibility of publication bias.

Objective: We aimed to replicate the tDCS methodology and findings of Cattaneo, Pisoni, and Papagno (2011, Neuroscience 183:64-70) in a new population sample.

Background: Chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq) can locate transcription factor binding sites on genomic scale. Although many models and programs are available to call peaks, none has dominated its competition in comparison studies.

Results: We propose a rigorous statistical model, the normal-exponential two-peak (NEXT-peak) model, which parallels the physical processes generating the empirical data, and which can naturally incorporate mappability information.
