In this research, the robot has been developed by applying a \"sinusoidal wave drive\" principle that allows robots to negotiate curved pipes and pipes of varying diameters by themselves. Previous papers reported the basic model robots to which this principle is applied. These robots show the principle's potential. In this paper a robot consisting of thirteen links is shown. Each link has an intelligent actuator that decreases the number of wirings, high performance to decentration processes, and high tolerance for electrical noise. We conducted experiments with this robot that show a wide range of applicable diameters from 36 to 180 [mm]. The robot can also negotiate the various shaped pipes and vertical pipes.

Mast cells are typical non-neuronal secretory cells and secrete inflammatory mediators such as histamine and cause allergic responses. It has been shown that SNARE (soluble N-ethyl maleimide-sensitive factor attachment protein receptor) proteins play an essential role in exocytotic release in both neuronal cells and non-neuronal secretory cells. To mimic the exocytotic processes in mast cells, we developed an artificial membrane fusion system using liposomes that contains SNARE proteins. To prepare liposomes that contain SNARE proteins, SNARE proteins expressed in E. coli were purified and reconstituted into liposomes by solubilization-reconstitution methods using octylglucoside as a detergent. The membrane fusion is monitored by FRET (fluorescent resonance energy transfer) between fluorescence labeled phospholipids in liposomes (NBD- and rhodamine- labeled phospholipids). Using this assay system, we found that SNAP23, syntaxin 3 and VAMP8 are involved in exocytotic release in mast cells","PeriodicalId":121329,"journal":{"name":"2006 IEEE International Symposium on MicroNanoMechanical and Human Science","volume":"SE-10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126574949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The germanium is an excellent material for infrared optical devices, whereas ultraprecision micro-machining of the germanium is difficult due to its brittleness. Micro grooving experiments are carried out on the (100), (110) and (111) surfaces of single crystal germanium substrates, and basic effects of the elliptical vibration on the ductile micro-machining are clarified as follows. Critical depth of cut to generate a completely fracture-free surface on the single crystal germanium is increased significantly in all crystal orientations on the (100) and (111) surfaces, and ultraprecision micro grooving is realized successfully at a large depth of cut of 1 mum by applying the elliptical vibration cutting. This improvement by the elliptical vibration cutting is considered to be caused by reduction of instantaneous uncut chip thickness and cutting force in each cycle of the elliptical vibration. When the rake angle becomes negative, influence of the crystal orientation on the critical depth of cut becomes negligible, while it is considerable at 0 degree. On the other hand, the rake angle does not have considerable influence on average values of the critical depth of cut between -20 to 0 degree.

From the complete genome sequence, about 4,400 genes are considered to exist on the genome. Selective and regulated expression of the genes is critical for bacterial adaptation to environment. Since the number of RNA polymerase, the enzyme responsible for transcription, is less than that of total genes, we proposed that the controlled distribution of RNA polymerase among 4,400 genes determines the genome expression pattern. In order to understand the molecular basis of genome regulation, we have been concerned with the analysis of all 300 transcription factors, which are involved in the functional modulation of RNA polymerase for switching the gene selectivity. For this purpose, we have performed the systematic search for target genes and promoters recognized by each transcription factor using the newly developed genomic SELEX system. Here we describe some results of this multi-scale genetics focusing on the protein-protein and protein-DNA interaction networks involved in the genome regulation. One hitherto undescribed finding is that the transcription factors form interplay networks, in which one transcription factor controls the expression of another factor and so on. The putative transcription factors with unidentified functions are often located on top of the hierarchy of transcription factor cascade.

It has been found that bundling of F-actin filaments is generated with various cationic species, such as Fe3+ , spermidine3+, cationic synthetic polypeptides. It has been regarded that these multivalent cations work as a paste to stick the like-charge filaments. In the past studies, the bundling phenomenon of F-actin has frequently been observed through the increase of the light scattering. There observations indicated the cooperative, continuous nature in the transition. In the present study, we performed the observation on the bundling phenomenon by use of fluorescent microscopy. We found that the bundling transition proceeds through the coexistence of single filaments and bundles, which corresponds to the continuous nature of the transition revealed from the measurement of the light scattering.
