Visually evoked potentials and background EEGs in the cerebral visual, somatosensory, and association areas (lateral suprasylvian gyrus), as well as in the lateral geniculate body (GL) and mesencephalic reticular formation were studied before and after unilateral destruction of the GL of unanes-thetized cat. Autocorrelograms and power spectra of background EEGs in various areas mainly showed ac...

The DNA replication-related element-binding factor (DREF) is a BED finger-type transcription factor that has important roles in cell cycle progression. In an earlier study, we showed that DREF is required for endoreplication during posterior scutellar macrochaete development. However, dynamic change in the dref expression in the cell lineage is unclear. In this study, we focused on the spatio-t...

Most hash-based structured peer-to-peer (HS-P2P) architectures proposed previously focus on stationary peer nodes. When peers move to new locations in the network, these schemes become cumbersome and inefficient in delivering messages. This paper proposes a mobile HS-P2P architecture, called Bristle, which allows nodes to move freely. A node can disseminate its location information through the ...

Stable localization of the signaling complex is essential for the robust morphogenesis of polarized cells. Cell elongation involves molecular signaling centers that coordinately regulate intracellular transport and cytoskeletal structures. In Drosophila bristle elongation, the protein kinase IKKε is activated at the distal tip of the growing bristle and regulates the shuttling movement of recyc...

We develop and implement a strategy to map QTL in two synthetic populations of Drosophila melanogaster each initiated with eight inbred founder strains. These recombinant populations allow simultaneous estimates of QTL location, effect, and frequency. Five X-linked QTL influencing bristle number were resolved to intervals of approximately 1.3 cM. We confirm previous observations of bristle numb...

The neurogenic genes of Drosophila act during many different times and places during development. It is thought their role is to repress cell fate within a group of equivalent cells and thus allow the singling out of discrete numbers of precursors. Amongst the genes at the neurogenic locus, Enhancer of split is a family of seven related genes that encode proteins containing the basic helix-loop...

We have investigated genetic interactions between spontaneous mutations affecting abdominal and sternopleural bristle number that have accumulated in 12 long-term selection lines derived from an inbred strain, and mutations at 14 candidate bristle number quantitative trait loci. The quantitative test for complementation was to cross the selection lines to an inbred wild-type strain (the control...

Thoracic responses between the Hybrid III model and the THUMS human body model were compared in three frontal impact severities for two belt (3-point and criss-cross), two belt load limiter (constant and degressive) and two airbag types (symmetric and non-symmetric). The thoracic responses were evaluated by measurements of chest deflections (mid-sternum and multi-point measured), chest excursio...

AIM The aim of the present study was to evaluate the effectiveness of different bristle designs of toothbrushes and the periodontal status among patients undergoing fixed orthodontic treatment. MATERIALS AND METHODS This randomized controlled trial (RCT) consisted of 45 adolescents (comprising 20 males and 25 females) undergoing fixed orthodontic treatment. The study participants were randoml...

With the aim of revealing genetic variation accumulated among closely related species during the course of evolution, this study focuses on loss of macrochaetae on the notum as one of the developmental anomalies seen in interspecific hybrids between Drosophila melanogaster and its closely related species. Interspecific hybrids between a line of D. melanogaster and D. simulans isofemale lines ex...
