Laparoscopic live donor nephrectomy (DN) has been established as a useful alternative to the traditional open methods of procuring kidneys. To maximize the advantages of the laparoendoscopic single-site (LESS) method, we applied natural orifice specimen extraction to LESS-DN. A 46-year-old woman with no previous abdominal surgery history volunteered to donate her left kidney to her husband and underwent single-port laparoscopic DN with transvaginal extraction. The procedure was completed without intraoperative complications. The kidney functioned well immediately after transplantation, and the donor and recipient were respectively discharged 2 days and 2 weeks postoperatively. Single-port laparoscopic DN and transvaginal graft extraction is feasible and safe.

<P>Zero- and one-dimensional metal nanocrystals were successfully fabricated with accurate control in size, shape, and position on semiconductor surfaces by using a novel <I>in situ</I> fabrication method of the nanocrystal with a biasing tungsten tip in transmission electron microscopy. The dominant mechanism of nanocrystal formation was identified mainly as local Joule heating-assisted electromigration through the direct observation of formation and growth processes of the nanocrystal. This method was applied to extracting metal atoms with an exceedingly faster growth rate (∼10<SUP>5</SUP> atoms/s) from a metal-oxide thin film to form a metal nanocrystal with any desired size and position. By real-time observation of the microstructure and concurrent electrical measurements, it was found that the nanostructure formation can be completely controlled into various shapes such as zero-dimensional nanodots and one-dimensional nanowires/nanorods.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancac3/2010/ancac3.2010.4.issue-6/nn901674p/production/images/medium/nn-2009-01674p_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn901674p'>ACS Electronic Supporting Info</A></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn901674p'>ACS Electronic Supporting Info</A></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn901674p'>ACS Electronic Supporting Info</A></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn901674p'>ACS Electronic Supporting Info</A></P>

<P>Sub-10 nm In(PO<SUB>3</SUB>)<SUB>3</SUB> nanocrystals (NCs) were created in an insulating matrix by rapid thermal annealing to form nanocomposite structures. On annealing at a temperature of 400 °C, P<SUB>2</SUB>O<SUB>5</SUB> NCs were formed by substituting P for Zn atoms in ZnO films via the kickout diffusion mechanism based on the fixed oxygen sublattice. On annealing at a higher temperature of 600 °C, however, In(PO<SUB>3</SUB>)<SUB>3</SUB> NCs were nucleated by diffusion of In atoms from the substrate into the sites of P<SUB>2</SUB>O<SUB>5</SUB> NCs that coalesced by moving atoms to neighboring grains in the strain relaxed region. The formation mechanisms of sub-10 nm In(PO<SUB>3</SUB>)<SUB>3</SUB> NCs in an insulating matrix due to rapid thermal annealing are described on the basis of the experimental results.</P>
