Els massatges a les sessions de psicomotricitat: perqu?? ??s important escoltar els infants, encara que no articulin paraules, tot el seu cos parla

Se expone una experiencia did??ctica dirigida a un grupo de alumnos de segundo ciclo de educaci??n infantil. Se desarrolla una actividad de psicomotricidad vinculada al masaje. El masaje infantil pretende transmitir a los ni??os sensaciones y canalizarlas, les ayuda a trabajar el esquema corporal integrando cada parte f??sica y emocional del cuerpo y adem??s, es una pr??ctica l??dica que les tranquiliza y relaja. Para el maestro o la maestra, puede ayudar a interpretar los mensajes de los ni??os: gestos, miradas, llantos, movimientos??? y por tanto, entender su mensaje. Finalmente, se enumeran los objetivos y contenidos del curriculum que pueden reforzarse con la pr??ctica del masaje infantil en las aulas

Toxoplasma gondii: further studies on the subpellicular network

The association of the pellicle with cytoskeletal elements in Toxoplasma gondii allows this parasite to maintain its mechanical integrity and makes possible its gliding motility and cell invasion. The inner membrane complex (IMC) resembles the flattened membrane sacs observed in free-living protozoa and these sacs have been found to associate with cytoskeletal proteins such as articulins. We used immunofluorescence microscopy to characterise the presence and distribution of plateins, a sub-family of articulins, in T. gondii tachyzoites. A dispersed labelling of the whole protozoan body was observed. Electron microscopy of detergent-extracted cells revealed the presence of a network of 10 nm filaments distributed throughout the parasite. These filaments were labelled with anti-platein antibodies. Screening the sequenced T. gondii genome, we obtained the sequence of an IMC predicted protein with 25% identity and 42% similarity to the platein isoform alpha 1 present in Euplotes aediculatus, but with 42% identity and 55% similarity to that found in Euglena gracilis, suggesting strong resemblance to articulins.
