<p>La idea de vincular a América Hispánica es vieja como la independencia de los países hispanoamericanos.

A new way of thinking and actingAmong the rich contributions of the Zapatista movement toward building an alternative is the recent project of the caracoles (conches) 1 , which undercuts many empty promises put forward by politicians and intellectuals. The project of the caracoles, according to Comandante Javier, "opens up new possibilities of resistance and autonomy for the indigenous peoples of Mexico and the world -a resistance which includes all those social sectors that struggle for democracy, for liberty and justice for all." As a commentator in Spain noted: "Zapatismo has become a tool which can be used by all rebellious forces that sail the sea of globalization. It invites us to build towards community and autonomy with the patience and tranquility of the conch."The idea of creating organizations to be used as tools to achieve certain objectives and values, and to ensure that autonomy and the motto mandar obedeciendo ("lead by obeying!") do not remain in the sphere of abstract concepts and incoherent words, is one of the most important contributions of the caracoles. Its creators are conscious of the limitations and the possibilities of the project.Subcomandante Marcos recognizes with a mixture of modesty and enthusiasm that the caracoles constitute "a small part of the world that we aspire to, which is made up of many worlds."

They used it "to summon the community" and as "an aid to hear the most distant words." Marcos, Chiapas: La Treceava Estela, July
The authors report electron microscopic findings in brain, bone marrow and liver biopsies in a case of juvenile Niemann-Pick disease (Crocker's type C). The diagnosis was supported by clinical data increase of blood sphingomyelin and vacuolated histiocytes in bone marrow and liver. Neurons and glial cells were filled with two types of cytosomes: classical multilamellar bodies and unusual pleiomorphic bodies. The latter type probably showed some lipofuscinic component. The relationship between type C and classical Niemann-Pick disease is discussed.
