Demonstration of scrapie strain diversity in infected PC12 cells.
Scrapie strain replication in the nerve growth factor-induced, differentiated PC12 cell culture system was examined. Differences in replication between mouse-derived agents were demonstrated, with the 139A scrapie strain yielding 100- to 1000-fold higher levels of infectivity than the ME7 scrapie strain. Replication was not detected in PC12 cells infected with either the hamster-derived 263K or...
متن کاملStrain-Associated Variations in Abnormal PrP Trafficking of Sheep Scrapie
Prion diseases are associated with the accumulation of an abnormal form of the host-coded prion protein (PrP). It is postulated that different tertiary or quaternary structures of infectious PrP provide the information necessary to code for strain properties. We show here that different light microscopic types of abnormal PrP (PrP(d)) accumulation found in each of 10 sheep scrapie cases corresp...
متن کاملScrapie.
A detailed review is presented of the history, geographical distribution, cause, epidemiology, clinical features, pathogenesis, pathology, diagnosis, prevention, control and economic effects of scrapie in sheep. Brief mention is made of the disease in goats and moufflon. The nature of the agent causing scrapie, the genetic control of the incubation period in sheep and the natural transmission o...
متن کاملImproving the performance of UPQC under unbalanced and distortional load conditions: A new control method
This paper presents a new control method for a three-phase four-wire Unified Power Quality Conditioner (UPQC) to deal with the problems of power quality under distortional and unbalanced load conditions. The proposed control approach is the combination of instantaneous power theory and Synchronous Reference Frame (SRF) theory which is optimized by using a self-tuning filter (STF) and without us...
متن کاملDecolorization of Cibacron Black w-55 under Alkaline Conditions by New Strain of Halomonas sp. Isolated from Textile Effluent
Among the 30 strains of moderately halophilic bacteria isolated from the salty effluents of textile industries around Qom city in central Iran, a Gram-negative rod shape bacterium designated as strain IP8 showed a remarkable ability in decolorizing of azo dyes over wide ranges of pH (7-11) and temperature (25-45 ºC), in presence of NaCl and Na2SO...
