The Cartwheel, archetypical ring galaxy with strong star formation activity concentrated in a peculiar annular structure, has been imaged with the CHANDRA ACIS-S instrument. We present here preliminary results, that confirm the high luminosity detected earlier with the ROSAT HRI. Many bright isolated sources are visible in the star-forming ring. A diffuse component at luminosity of the order of...
Background and Study Aim. The purpose of the study is a biomechanical examination inclusion active flexibility in artistic gymnastic movements requiring mobility (muscles' ability to stretch), other motor abilities such as force, power, etc.
 Material Methods. included 17 girl gymnasts aged 7-9 years old, with body height 140.7±10.2, weight 34.1±6.4, mass index 17.6±3.0. Data collection wa...
Centrioles are evolutionarily conserved macromolecular structures that are fundamental to form cilia, flagella, and centrosomes. Centrioles are 9-fold symmetrical microtubule-based cylindrical barrels comprising three regions that can be clearly distinguished in the Chlamydomonas reinhardtii organelle: an ∼100-nm-long proximal region harboring a cartwheel; an ∼250-nm-long central core region co...
ow centrioles and basal bodies assemble is a longstanding puzzle in cell biology. To address this problem, we analyzed a novel basal body-defective Chlamydomonas reinhardtii mutant isolated from a collection of flagella-less mutants. This mutant, bld10 , displayed disorganized mitotic spindles and cytoplasmic microtubules, resulting in abnormal cell division and slow growth. Electron microscopi...
