INTRODUCTION There is increasing evidence that imaging with [123I]FP-CIT SPECT is helpful in differentiating dementia with Lewy bodies (DLB) from Alzheimer's disease (AD) but it is not known how well the scan performs in differentiating DLB from frontotemporal dementia (FTD). METHOD We compared the striatal dopamine transporter (DAT) binding in FTD… (More)
Forest degradation in the Brazilian Amazon due to selective logging and forest fires may greatly increase the human footprint beyond outright deforestation. We demonstrate a method to quantify annual deforestation and degradation simultaneously across the entire region for the years 2000–2010 using high-resolution Landsat satellite imagery. Combining… (More)
Measurements of the amplitude and latency of the P3b component of the event-related potential (ERP), simple reaction time (SRT) and four psychomotor tests (VAS, DSST, DSp and CFF) were made on 12 male subjects (aged 19-24 years) 1.0-1.5 and 4.0-4.5 h after single oral doses of triprolidine (7.5 mg), terfenadine (60 mg) and placebo. Neither triprolidine nor… (More)
