Much attention has been paid to the cross-coupling reaction of organosilicon compounds due to their stability, non-toxicity, and natural abundance of silicon. In addition, the silicon-based cross-coupling has many advantages over other cross-coupling protocols. Successful examples of the silicon-based cross-coupling reaction are reviewed, focusing especially on the advances made in the last decade. Having had a number of highly effective palladium catalysts developed mainly for other cross-coupling reactions, the development of the silicon-based protocol owes heavily to the design of organosilicon reagents which effectively undergo transmetalation, a key elemental step of the silicon-based cross-coupling reaction. This tutorial review thus classifies various organosilicon reagents depending on substituents on silicon and surveys their cross-coupling reactions with various electrophiles. © 2011 The Royal Society of Chemistry.

This review presents highlights of our latest results of studies directed at developing protein-based smart nanotubes for biomedical applications. These practical biocylinders were prepared using an alternate layer-by-layer (LbL) assembly of protein and oppositely charged poly(amino acid) into a nanoporous polycarbonate (PC) membrane (pore diameter, 400 nm), with subsequent dissolution of the template. The tube wall typically comprises six layers of poly-l-arginine (PLA) and human serum albumin (HSA) [(PLA/HSA) 3]. The obtained (PLA/HSA) 3 nanotubes (NTs) can be dispersed in aqueous medium and are hydrated significantly. Several ligands for HSA, such as zinc(ii) protoporphyrin IX (ZnPP), were bound to the HSA component in the cylindrical wall. Similar NTs comprising recombinant HSA mutant, which has a strong binding affinity for ZnPP, captured the ligand more tightly. The Fe 3O 4-coated NTs can be collected easily by exposure to a magnetic field. The hybrid NTs bearing a single avidin layer as an internal wall captured biotin-labeled nanoparticles into the central channel when their particle size is sufficiently small to enter the pores. The NTs with an antibody surface interior entrapped human hepatitis B virus with size selectivity. It is noteworthy that the infectious Dane particles were encapsulated completely into the hollows. Other HSA-based NTs having an α-glucosidase inner wall hydrolysed a glucopyranoside to yield α-d-glucose. A perspective of the practical use of the protein-based NTs is also described.

A novel hemoglobin-albumin complex which has high stability of the oxygenated form, has high biocompatibility, and is easily prepared (synthesized), and an artificial plasma expander and an artificial oxygen carrier containing the complex are provided. The hemoglobin-albumin complex of the invention is characterized by having hemoglobin as the core, and albumin as the shell bound via a crosslinker to the above hemoglobin. Also, the artificial oxygen carrier of the invention is characterized by containing the hemoglobin-albumin complex of the invention.

There is provided an information processing apparatus including: an input unit inputting first vibration information observed from a moving body; a generating unit generating second vibration information based on a periodic function including at least one parameter that models periodic motion of the moving body; and an estimating unit estimating the at least one parameter based on a comparison result for the first vibration information inputted by the input unit and the second vibration information generated by the generating unit. The estimating unit repeatedly estimates the at least one parameter based on a comparison result for the first vibration information and the second vibration information that has been regenerated by the generating unit using the estimated at least one parameter.
