ABSTRACT Polarization of the C. elegans embryo depends on the sperm-contributed centrosome, which cues a retraction of the actomyosin cortex to the opposite end of the embryo by an unknown mechanism. New evidence reveals that the sperm donates a second polarizing cue that may locally relax the actomyosin cortex near the point of sperm entry.

    ABSTRACT: Centrioles and basal bodies are MT based structures that present a highly conserved ninefold symmetry. Centrioles can be found at the core of the centrosome where they participate in PCM recruitment and organization, contributing to cytoplasmic MT nucleation. Basal bodies are normally located closely to the plasma membrane where they are responsible for axoneme assembly to form structures such as cilia or flagella. While it is well accepted that these organelles have important roles in cell and tissue organization, their contribution to certain phases of animal development is still not entirely established. Here we review the role of centrosomes and cilia in Drosophila melanogaster and briefly discuss the implications of these findings to other model organisms.

    ABSTRACT: The dynamic running performance of a four-track vehicle (known as a crawler vehicle) in deep snow is analyzed. The modeling of the vehicle is easily completed by use of bond graphs. The simulation results by use of bond graph software 20-sim are as follows: the fundamental mechanism of the vehicle running in the deep is that the crawler unit is swung by the resistance of the snow around the center of the drive shaft. Furthermore the frequency and amplitude of the swing changes with the amount of snow resistance

    ABSTRACT: "Germ granules" are cytoplasmic, nonmembrane-bound organelles unique to germline. Germ granules share components with the P bodies and stress granules of somatic cells, but also contain proteins and RNAs uniquely required for germ cell development. In this review, we focus on recent advances in our understanding of germ granule assembly, dynamics, and function. One hypothesis is that germ granules operate as hubs for the posttranscriptional control of gene expression, a function at the core of the germ cell differentiation program.
