here Spiders are the most successful venomous animals and the most abundant terrestrial predators.Their remarkable success is due in large part to their ingenious exploitation of silk and the evolution of pharmacologically complex venoms that ensure rapid subjugation of prey.Most spider venoms are dominated by disulfide-rich peptides that typically
Novelties in Grindelia (Asteraceae: Astereae) from South America
Three new species of Grindelia Willd.are described and illustrated: G.argentina, G.gaucha and G.atlantica. The first two are related with G.buphthalmoides DC.,andthe last is allied here with G.orientalis Bartoli, Tortosa & G.Rua. A key to segregate the merrick backcountry wet cat food speci
Intermittent hypoxia can aggravate motor neuronal loss and cognitive dysfunction in ALS mice.
BackgroundPatients click here with ALS may be exposed to variable degrees of chronic intermittent hypoxia.However, all previous experimental studies on the effects of hypoxia in ALS have only used a sustained hypoxia model and it is possible that chronic intermittent hypoxia exerts effects via a different molecular mechanism from that of sustained
Application of ICEEMDAN Energy Entropy and AFSA-SVM for Fault Diagnosis of Hoist Sheave Bearing
The mine hoist sheave bearing is a large heavy-duty bearing, located in a derrick of tens of meters.Aiming at the difficulty of sheave bearing metabo 15-gauge finish nailer cordless fault diagnosis, a combined fault-diagnosis method based on the improved complete ensemble EMD (ICEEMDAN) energy entropy and support vector machine (SVM) optimized by a
