Metastatic Malignant Granular Cell Tumor in the Lymph Node: A Cytological Report With Immunocytochemical Analysis.

Granular cell tumors (GCTs) are relatively rare, whereas malignant GCTs are extremely rare. This brief report describes a cytological case of metastatic malignant GCT in the lymph node with immunocytochemical analysis. A 77 years old Japanese female with a history of surgical resection for malignant GCT in the back 8 years earlier presented with swelling of the right neck.

Materials Nanoarchitectonics for Advanced Devices.

Advances in nanotechnology have made it possible to observe and evaluate structures down to the atomic and molecular level. The next step in the development of functional materials is to apply the knowledge of nanotechnology to materials sciences. This is the role of nanoarchitectonics, which is a concept of post-nanotechnology.

Mechanoelectrical Transduction through Anion Recognition with Naphthalenediimide Monolayers at the Air-Water Interface.

In biological systems, various stimuli and energies are transduced into membrane potentials via ion transport or binding. The application of this concept to artificial devices may result in biomimetic signal transmitters and energy harvesters. In this study, we investigated the mechanical control of fluoride anion recognition with naphthalenediimide (NDI) monolayers at the air-water interface.

Lateral nanoarchitectonics from nano to life: ongoing challenges in interfacial chemical science.

Lateral nanoarchitectonics is a method of precisely designing functional materials from atoms, molecules, and nanomaterials (so-called nanounits) in two-dimensional (2D) space using knowledge of nanotechnology. Similar strategies can be seen in biological systems; in particular, biological membranes ingeniously arrange and organise functional units within a single layer of units to create powerful systems for photosynthesis or signal transduction and others. When our major lateral nanoarchitectural approaches such as layer-by-layer (LbL) assembly and Langmuir-Blodgett (LB) films are compared with biological membranes, one finds that lateral nanoarchitectonics has potential to become a powerful tool for designing advanced functional nanoscale systems; however, it is still rather not well-developed with a great deal of unexplored possibilities.
