BACKGROUND We analyzed serial data in patients with clinically stable monoclonal gammopathy to determine the total variation of serum M-spikes [measured with serum protein electrophoresis (SPEP)], urine M-spikes [measured with urine protein electrophoresis (UPEP)], and monoclonal serum free light chain (FLC) concentrations measured with immunoassay. METHODS Patients to be studied were identif...

This study was conducted to examine in vitro antibacterialpotential from seed methanol extract of Peganum harmala (L) against some fish pathogenic bacteria including Lactococcus garvieae, Aeromonas hydrophila, Yersinia ruckeri and Pseuodomonas putida isolated from diseased rainbow trout (Oncorhynchus mykiss). The antibacterial activity of extracts was evaluated using disc diffusion assay, m...

Ten patients treated with electroconvulsive therapy (ECT) only were followed with serial sleep polysomnographic recordings and dexamethasone suppression tests (DSTs). Both biological correlates of depression showed improvement with ECT. The use of serial sleep measures and serial DSTs in monitoring the clinical response to ECT is discussed.

Although the concentration of N-acetylaspartate (NAA) is often used as a neuronal integrity marker, its normal temporal variations are not well documented. To assess them over the 1-2 year periods of typical clinical trials, the whole-brain NAA concentration was measured longitudinally, over 4 years, in a cohort of healthy young adults. No significant change (adjusted for both sex and age) was ...

The worldwide occurrence of complex climate-induced ecological shifts in marine systems is one of the major challenges in sustainable bio-resources management. The occurrence of ecological environment-driven shifts was studied in the Southern Caspian Sea using the "shiftogram" method on available fisheries-related (i.e. commercially important bentho-pelagic fish stocks) ecological and climatic ...
