The Space Tethered Autonomous Robotic Satellite (STARS) is being developed in Kagawa University and it will be launched by the H-IIA rocket by Japan Aerospace Exploration Agency (JAXA) in summer 2007. The main purpose of the STARS is technical verification for a tethered space robot proposed in 1995. The STARS consists of mother and daughter satellites connected by tether. The mother satellite ...

The two centrioles of the centrosome differ in age and function. Although the mother centriole mediates most centrosome-dependent processes, the role of the daughter remains poorly understood. A recent study has implicated the daughter centriole in centriole amplification in multiciliated cells, but its contribution to primary ciliogenesis is unclear. We found that manipulations that prevent da...

Centriole duplication occurs once per cell cycle, ensuring that each cell contains two centrosomes, each containing a mother-daughter pair of tightly engaged centrioles at mitotic entry. Loss of the tight engagement between mother and daughter centrioles appears to license the next round of centriole duplication. However, the molecular mechanisms regulating this process remain largely unknown. ...

Primer T he growth and development of all eukaryotes depends on the process of asymmetric cell division, in which a single cell gives rise to two genetically identical cells that adopt distinct fates [1,2]. Asymmetry occurs when two cells are exposed to different environmental stimuli or when specific mRNAs or proteins (known as cell fate determinants) are segregated unequally. In recent years,...

this article studies sir walter scott’s use of the family-as-nation trope in ivanhoe and anne of geierstein. the importance of this trope in his figuration of nationhood is discerned by carrying out a close reading of the texts and placing them in their historical context, which primarily consists of a comparison with edmund burke and maria edgeworth. consequently, his position is revealed as b...

The mechanisms of development, growth and rupture of cerebral aneurysms are still incompletely understood. However, blood flow is believed to have a major impact. Some aneurysms develop smaller aneurysms, so-­‐called daughter aneurysms -­‐ see figure. In this study the influence of these daughter aneurysms was investigated. The blood flow with and without these daughter aneurysms was simulated ...

Description of the device and methodology The Advanced Bifurcation Systems (ABS Los Angeles, CA, USA) line of modular bifurcation systems is a novel stent platform designed to uniformly mould all coronary bifurcations regardless of angles and sizes in a simple, intuitive procedure. Orientation and alignment of main branch (mother) and side branch (daughter) segments is automatic with complete t...

RESUMEN Este artículo busca conceptuar la partera pos-moderna, definiéndola como aquella que tiene una postura en relación a la biomedicina y a otros sistemas de conocimiento, moviéndose fluidificado entre ellos para ayudar a las mujeres que asiste. Es consciente, culturalmente competente y políticamente enganchada. Trabaja con recursos de su conocimiento específico, aliados a los intereses de ...

During asymmetric mitosis, both in male Drosophila germline stem cells and in mouse embryo neural progenitors, the mother centrosome is retained by the self-renewed cell; hence suggesting that mother centrosome inheritance might contribute to stemness. We test this hypothesis in Drosophila neuroblasts (NBs) tracing photo converted centrioles and a daughter-centriole-specific marker generated by...

PURPOSE Parent-child conversations about human papillomavirus (HPV) vaccine may provide parents with the opportunity to talk with their daughters about sexual health. We sought to characterize mothers' communication with their adolescent daughters about HPV vaccine. METHODS We surveyed 609 mothers of girls aged between 11 and 20 years living in North Carolina in Fall 2008. We used logistic re...
