Significantly decreased platelet serotonin contents were measured in rheumatoid arthritis, systemic lupus erythematosus (SLE), progressive systemic sclerosis, and mixed connective tissue disease. An inverse relationship between platelet serotonin levels and clinical disease activity was observed in both rheumatoid arthritis and systemic lupus erythematosus.(More)
Sera from patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) were assessed for in vitro platelet activation as measured by serotonin release; 24% (30) of 124 tested RA sera and 51% (35) of 69 SLE sera induced a significant 3H serotonin release. Investigation of 17 synovial fluid samples from RA patients revealed significant(More)
A processing of remotely-sensed Fraction of Absorbed Photosynthetically Active Radiation (fAPAR) time series at 1-km spatial resolution is established to estimate sugarcane yield over the state of Sã o Paulo, Brazil. It includes selecting adequate time series according to the signal spatial purity, using thermal time instead of calendar time and smoothing(More)
The objective of the Mars Crop Yield Forecasting Systems (MCYFS) is to provide precise, scientific, traceable independent and timely forecasts for the main crops yields at EU level. The forecasts and analysis are used since 2001 as a benchmark by analysts from DG – Agriculture and Rural Development in charge of food balance estimates. The system is(More)
Within the MARS Crop Yield Forecasting System (MCYFS; Royer and Genovese, 2004) of the European Commission vegetation indicators like NDVI, SAVI and fAPAR are operationally derived for daily, decadal and monthly time steps. Besides low resolution sensors as SPOT-VGT and NOAA-AVHRR, medium resolution data from TERRA/AQUA-MODIS or ENVISAT-MERIS are used at(More)
Rice is the staple food for about half of the world’s population. Although global production has more than doubled in the last 40 years, food security problems still persist and need to be managed based on early and reliable forecasting activities. This is especially true since the frequency of extreme weather events is forecasted to increase by the(More)
Using a C1q binding test, circulating immune complexes (IC) were detected in 33.3% of sera from 138 patients and in 19.4% of 124 spinal fluid samples from patients with multiple sclerosis. Most often they occur in sera alone. As a rule their detectable amount is small in sera as well as in spinal fluids. IC were observed with equal frequency during acute(More)
Methodological aspects of quantitative serum protein determinations, using a newly developed laser nephelometer (PDQTM laser nephelometer, Hyland), are reported. For within-day precision, determination of the four serum proteins IgG, IgA, IgM and C'3, showed coefficients of variation between 2.5% and 4.6%. For precision from day to day, the average(More)
Plasma exchange was performed in two patients with classical rheumatoid arthritis, complicated in one case by necrotic vasculitis, in the other by mononeuritis multiplex. Immediate improvement in the peripheral circulation was observed in both patients with subsequent healing of necroses and nerve function respectively. The treatment was combined with(More)
