The nucleus in eukaryotic cells can move within the cytoplasm, and its position is crucial for many cellular events, including migration and differentiation. Nuclear anchorage and movement can be achieved through association of outer nuclear membrane (ONM) proteins with the three cytoskeletal systems. Two decades ago studies described C. elegans mutants with defects in such events, but only rec...

The nuclear envelope not only compartmentalizes the genome but is also home to the SUN-KASH domain proteins, which play essential roles both in genome organization and in linking the nucleus to the cytoskeleton. In interphase fission yeast cells, centromeres are clustered near the nuclear periphery. A recent report demonstrates that the inner nuclear membrane SUN domain protein Sad1 and a novel...

Many countries worldwide have recognized the importance of implementing e-government strategies as one of the key options for improving the delivery of government services to their citizens. This has been enhanced by developments in information and communication technology (ICT) coupled with tangible economic benefits that are attached to international collaborative networks brought about by va...

The ambipolar diffusion length is measured in strained &Gal-&/InP quantum wells for several mole fractions in the interval 0.3 <X <0.8 by cathodoluminescence. The ambipolar diffusion length is found to have a significantly higher value in the lower indium mole fraction samples corresponding to tensile-strained wells. This longer diffusion length for the tensile samples is consistent with result...

Over the last few years, several novel proteins have been identified that facilitate the physical integration of the nucleus with the cytoplasmic compartment. The majority belong to the evolutionarily conserved KASH [klarsicht/ANC-1 (anchorage 1)/SYNE (synaptic nuclear envelope protein) homology]-domain family, which function primarily as exclusive outer nuclear membrane scaffolds that associat...
