Objective: To evaluate the prevalence, pathogenesis particular syncope, near syncope in children involved in elite sport.

Material And Methods: The study involved 500 young elite athletes aged 9-18 years (mean age 16.

[The Point Mutation in NOGGIN2 Protein That Enhances Its Ability to Bind Activin].

Earlier we have revealed the ability of Noggin family proteins to bind a member of the TUF-β superfamily, ActivinB, and to repress the Activin-dependent Smad2 signaling cascade. In the present work we have characterized a mutant of the Xenopus laevis Noggin2, bearing the substitution W203R. We have shown that this point mutation enhances the affinity of Noggin2 to ActivinB, while weakens its affinity to BMP.
