A technique that combines scanning electrochemical microscopy (SECM) and optical microscopy (OM) was implemented with a new probe tip. The tip for scanning electrochemicaVoptical microscopy (SECM/OM) was constructed by insulating a typical gold-coated near-field scanning optical microscopy tip using electrophoretic anodic paint. Once fabricated, the tip was characterized by steady-state cyclic ...

Aspergillus nidulans hyphae have long tip cells that are separated from short basal cells by septa. Basal cells average 40 microm long with three or four nuclei. Septation follows parasynchronous mitoses in the tip cell and seems to occur at premarked sites, but how these sites are established is unclear. A. nidulans strains with the hypA1 mutation are wildtype at 28 degrees C but if shifted to...

IMPORTANCE Successful surgical correction of nasal tip position requires preoperative analysis. Perceived adequate nasal tip position depends on its relationship with other facial features. Nasal tip position can be affected by the subnasal contour, proportion of facial height, and relative facial size and shape. The relation of these factors to the nasolabial angle may not be as important as p...

BACKGROUND Malignant gliomas represent one group of tumors that poorly respond to ionizing radiation (IR) alone or combined with chemotherapeutic agents because of the intrinsic or acquired resistance. In this study, TIP-1 was identified as one novel protein that confers resistance of glioma cells to IR. METHODOLOGY/PRINCIPAL FINDINGS Meta-analysis indicated that high TIP-1 expression levels ...

IMPORTANCE Imparting surgical change to the nasal tip remains one of the most challenging aspects of rhinoplasty. The surgeon must assess the tip preoperatively and execute the necessary maneuvers to impart the desired change. OBJECTIVE To assess nasal tip resistance to compression in a cadaveric model before and after specific rhinoplasty maneuvers using a novel method. DESIGN, SETTING, AN...

We predict theoretically that surface plasmon polaritons propagating toward the tip of a tapered plasmonic waveguide are slowed down and asymptotically stopped when they tend to the tip, never actually reaching it (the travel time to the tip is logarithmically divergent). This phenomenon causes accumulation of energy and giant local fields at the tip. There are various prospective applications ...

AIM To assess the value of contrast versus plain radiography in determining radio-opaque long line tip position in neonates. METHODS In a prospective study, plain radiography was performed after insertion of radio-opaque long lines. If the line tip was not visible on the plain film, a second film with contrast was obtained in an attempt to visualise the tip. RESULTS Sixty eight lines were i...

Management of the nasal tip is the most challenging step in rhinoplasty. Control over nasal tip projection is essential. A variety of techniques can be used to improve the position of nasal tip. The aim of the present study was to compare the changes of nasal tip between a novel tip plasty technique and the conventional sheen graft one. In this clinical trial study, 60 patients referring for rh...
