Are serum ghrelin concentrations increased in children with growth hormone insensitivity and decrease during long-term insulinlike growth factor-I treatment?
Growth hormone resistance and low IGF-I levels are associated with elevated ghrelin levels, which may potentiate GH secretion and adiposity in these children. Suppression of ghrelin during IGF-I treatment suggests a novel mechanism potentially regulating ghrelin levels.
Verbal rehearsal speed may be less influential for EF quality in CI users than for NH controls, whereas rapid automatized labeling skills and EF are closely related in both groups. CI users may develop processing strategies in EF tasks that differ from the covert speech strategies routinely employed by NH individuals.
