Computations that neurons perform in networks: lessons learned from a Sixteenth Century shoemaker

Creator:: Mpitsos, George J. and Edstrom, John P.
Abstract:: Cognitive and other neural processes emerge from the interactions be- tween neurons. Major advances have been made in studying networks in which the interac- fions occur instantaneously by means ofgraded synapses (Guckenheimer and Rowat, I 997). In other networks, the interaction between neurons involves time-delayed signals (action potentials or spikes)...

Biogeographically distinct controls on C₃ and C₄ grass distributions: merging community and physiological ecology

Creator:: Griffith, Daniel M., Anderson, T. Michael, Osborne, Colin P., Strömberg, Caroline A. E., Forrestel, Elisabeth J., and Still, Christopher J.
Abstract:: AIM: C₄ photosynthesis is an adaptation that maintains efficient carbon assimilation in warm and low-CO₂ conditions. Due to the importance of C₄ grasses for carbon and surface energy fluxes numerous models have been proposed to describe their spatial distribution and forecast responses to climate change. These models often rely on...

Abstract:: L-α-glycerophosphate oxidase is an FAD-dependent enzyme that catalyzes the oxidation of L-α-glycerophosphate (Glp) by molecular oxygen to generate dihydroxyacetone phosphate (DHAP) and hydrogen peroxide (H₂O₂). The catalytic properties of the recombinant His₆-GlpO from Mycoplasma pneumoniae (His₆-MpGlpO) were investigated with transient and steady-state kinetics and ligand binding. The results indicate that...

Abstract:: The formation of hydrogen peroxide (H₂O₂) by the FAD-dependent α-glycerophosphate oxidase (GlpO), is important for the pathogenesis of Streptococcus pneumoniae and Mycoplasma pneumoniae. The structurally known GlpO from Streptococcus sp. (SspGlpO) is similar to the pneumococcal protein (SpGlpO) and provides a guide for drug design against that target. However, M....
