Efficacy of temporal processing training to improve phonological awareness among dyslexic and normal reading students.

One of the leading theories for dyslexia suggests that it is the result of a difficulty in auditory temporal processing (ATP). This theory, as well as others, is supported by studies showing group differences and correlation between phonological awareness and ATP. However, these studies do not provide causal relationship.

Phosphorylation of SPICK2, an AKT2 channel homologue from Samanea motor cells.

SPICK2, a homologue of the weakly-inward-rectifying Shaker-like Arabidopsis K channel, AKT2, is a candidate K+-influx channel participating in light- and clock-regulated leaf movements of the legume, Samanea saman. Light and the biological clock regulate the in situ K+-influx channel activity differentially in extensor and flexor halves of the pulvinus (the S. saman leaf motor organ), and also-though differently-the transcript level of SPICK2 in the pulvinus.

Plasma membrane aquaporins in the motor cells of Samanea saman: diurnal and circadian regulation.

Leaf-moving organs, remarkable for the rhythmic volume changes of their motor cells, served as a model system in which to study the regulation of membrane water fluxes. Two plasma membrane intrinsic protein homolog genes, SsAQP1 and SsAQP2, were cloned from these organs and characterized as aquaporins in Xenopus laevis oocytes. Osmotic water permeability (P(f)) was 10 times higher in SsAQP2-expressing oocytes than in SsAQP1-expressing oocytes.
