  Treating hadronic flavor symmetries with quantum algebras U_q(su_n) leads to
interesting consequences such as: new mass sum rules for hadrons 1^-, (1/2)^+,
(3/2)^+ of improved accuracy; possibility to label different flavors
topologically - by torus winding number; properly fixed deformation parameter q
in case of baryons is linked in a simplest way to the Cabibbo angle \theta_C,
that suggests for \theta_C the exact value {\pi}/{14}. In this connection, we
discuss the possibility that this angle and the Cabibbo mixing as a whole take
its origin in noncommutativity of some additional, with regard to 3+1,
space-time dimensions.
