| HGPD ("http://www.HGPD.jp/":http://www.HGPD.jp/) is a unique database that stores information on a set of human Gateway entry clones in addition to protein expression data. HGPD was launched in November 2008 and, since then, 33,275 human Gateway entry clones have been constructed from ORFs of full-length cDNAs, thus representing the largest collection in the world. Sequence information and protein expression of Gateway entry clones can also be retrieved from HGPD. The majority of analysis data for cDNA sequences in HGPD are shared with the FLJ Human cDNA Database ("http://flj.hinv.jp/v01/cgi/index.cgi":http://flj.hinv.jp/v01/cgi/index.cgi), which was constructed as human cDNA sequence analysis database focusing on mRNA... |

| Human T-cell leukemia virus type I (HTLV-I) is a retrovirus that causes adult T-cell leukemia. The male-to-female transmission is stronger than the reverse, so the carrier proportion of women is greater than that of men. On the other hand, since the mother-to-child transmission route via the breast-feeding is common for baby boys and girls, it has been thought the HTLV-I proportions of boys and girls are the same until now. A question arises as to whether the ‘innate protection powers against human virus’ are the same between males and females. We utilize HTLV-I infection blood donor data in 1995-1998 and case data of main infectious diseases such as influenza, mumps, herpangina, hand-hoot-and-mouse disease, chicken pox, etc. Blood... |

| This document presents the original approach for estimating parameters of proteolysis process. Data used to fit the model are taken from mass
spectrometric experiments. For parameters estimation the Levenberg-Marquadt algorithm is used. The motivation for model is a hypothesis
that discrimination between cancer patients and healthy donors can be based on activity of peptide cleaving enzymes (i.e. peptidases). |

| The fossil record of Baurusuchidae Mesoeucrocodylia in the General Salgado county and its surroundings is one of the best regarding preservation, completeness and articulation of skull and skeleton remains, including specimens that shown even the most delicate bone structures and cartilaginous tissues. 

One of them, UFRJ DG 288-R, has preserved its skull and about 80% of its skeleton. During the removal of the rock matrix, on what should be the specimen’s abdominal region, together with fragments of gastralia were observed some small well-polished weathered angulous to subrounded clasts, presumed to be gastroliths. 

These xenoliths occur in a restrict cluster, where at least... |

| The aim of this study was to investigate the role of paclitaxel on RAB family of genes in primary breast cancer cell lines. The cancer breast cells obtained from 40 women during mastectomy were used to address this issue. The group included patients with intraductal breast cancer - lesions in I or II advancement level by TNM classification and G1-G2 by Bloom classification. (tumor dimensions up to 2.0 cm without metastases to lymph nodes). Cytostatic drugs before surgery were not administered to these patients. The cultures were conducted in 25 cm^2^ plastic containers at RPMI medium with addiction of 10% fetal bovine serum (FBS) at the standard conditions. After reaching concentration levels of 10 000/ml of the cells, the cultures were treated with 60... |

| Numerous scenarios of emissions growth presume that it can not grow infinitely: there are certain limits that may not or must not be exceeded. Applying the theory of pulsing logistic growth, I detected two pulses of logistic growth. This led me to the conclusion that constructing a scenario of emissions growth one should pay attention to the fact that limits to their growth do not remain constant. |

| The soils of tropical tasar plantation fields in general are sloppy and are primarily deficient of nutrition due to top soil erosion and constant leaf productivity exploitation to rear tasar silk insect, Antheraea mylitta Drury. The rainfed field of Terminalia tomentosa (W&A) plantation has been evaluated for soil fortification with green mulching through legumes, Sun hemp (Crotalaria juncea), Daincha (Sesbania aculeata), Green gram (Vigna radiatus) and Black gram (Vigna mungo) during rainy season. The mulching has enhanced the water holding, moisture retention, electrical conductivity, organic carbon, nitrogen (N) and potassium (K) and reduced the bulk density and pore space of soil. Among the legumes, Sun hemp has shown higher improvement of... |

| Exploitation of commodities exchanged in mutualistic interactions has been broadly documented, but typically involve the exploitation of a reward rather than a service. Further, examples of exploiter species are extremely rare in certain groups of animals, such as spiders. In 2008 and 2009, we investigated the potential exploitation by an orb-weaving spider (Eustala oblonga) of the plant protection services of ants on an ant-defended acacia (Acacia melanocerus) in lowland rainforest in central Panama. Despite vigorous patrolling of the acacias by the very pugnacious ants (Pseudomyrmex satanicus), we observed the spiders constructing orb webs among the branches at night and resting quietly during the day on the leaves or at the bases of the thorns in... |

| We ran an experiment where the subjects initially played a four-round dictator game, after which each subject was shown either a set of positive images or a set of negative images. Finally the subjects played another four-round dictator game.
The effect of the sign of images shown is clear on the players’ behaviors: positive images have moderate effects on charitable behavior while negative images dramatically increase charity.
We could therefore infer from our experimental results that showing negative images of the Haitian and Chilean catastrophes to the international public would have significant positive impacts on international donations to the victims and the rebuilding programs in both countries. |

| Groundwater resources play a key role in supplying water for domestic, industrial, agricultural, and ecological functions on the Canadian prairies. The current study investigates potential temporal trends in groundwater levels for the Canadian province of Saskatchewan over the past several decades. Overall, the large majority of areally distributed stations throughout Saskatchewan with increasing groundwater level time trends suggests that this hydrogeological resource is growing in quantity and is not under current threat from depletion. |

| Silk production from opisthosomal glands is a defining characteristic of spiders (Araneae). Silk emerges from spigots (modified setae) borne on spinnerets (modified appendages). Spigots from _Attercopus fimbriunguis_ (Shear, Selden & Rolfe, 1987^1^), from Middle Devonian (386 Ma) strata of Gilboa, New York were described in 1989^2^ as evidence for the oldest spider and the first use of silk by animals. Slightly younger (374 Ma) material from South Mountain, New York, conspecific with _A. fimbriunguis_, includes spigots and other evidence which elucidate the evolution of early Araneae and the origin of spider silk. No known _Attercopus_ spigots, including the original specimen^2^, occur on true spinnerets but are arranged along the edges of plates.... |

| Large-scale utilization of wood which command absolute majority in biomass for functional carbon precursors contributes to reduce greenhouse effect. Wood char generally has a limit on material usage because of its non-graphitic structure^1^, so we developed a new functional wood char by iron-, or nickel-catalyzed carbonization, which has a graphite-like structure with mesopores good for electroconductivity and liquid phase adsorption capacity for macro molecules^2-5^. However the fine structure of the wood char is still not clear. Here we report more than 70 wt % of iron-catalyzed wood char is filled with chained carbon shells formed by 3~20 defective stacking layers of carbon hexagonal planes, which look like nanometer-sized worms swarm. We name them... |

| Rehabilitation of degraded land in arid and semiarid environments often involves excluding livestock from degraded sites, creating what are usually but unfortunately not consistently, called _exclosures_. Their main objective is to allow native vegetation to regenerate as a means of providing fodder and woody biomass, to reduce soil erosion and to increase rain water infiltration. We are concerned that some of the alternative names for this practice that are reported in the international literature, including _closed area_, _area closure_ and _enclosure_, may lead to confusion and misunderstanding, especially when these are used as synonyms. Here we aim to illustrate the difference between exclosures and enclosures using recent ecological and... |

| Recent years have seen the emergence of several major initiatives supporting the development of biodiversity informatics infrastructures. In Europe examples include: EDIT – the European Distributed Institute of Taxonomy; LifeWatch – a biodiversity analytical platform integrating observatories, databases, processing and computational capacity; and SYNTHESYS – funding researcher access to a network of taxonomic collections, laboratories and libraries. These European projects alone represent a spend of approximately 35 Million Euros, with funding contingent on the collaboration of numerous geographically dispersed institutional partners. In this presentation we will review the major informatics products of these initiatives;... |

| Multiple demands comprise the efficiency of attentional control. There is abundant evidence that when an individual attempts two or more attentionally demanding activities at the same time, the allocation of attention to the tasks is limited and performance suffers as a result. Yet, recent technological innovations require many individuals to manage multiple digital technologies simultaneously or to switch attentional control between tasks. The ability to multitask with various digital technologies involves dividing attention, switching between tasks, and keeping track of multiple strands of information in working memory. |

| The role of prefrontal cortex in working memory (WM) is well established. However, questions remain regarding the topography and “domain-specific differentiation” of different types of information processing in the cortex. While it has been theorized that dorsolateral (DPFC) and ventrolateral (VPFC) prefrontal cortex preferentially process spatial and object WM, respectively, both electrophysiological evidence in the monkey and neuroimaging in the human have largely failed to demonstrate such regional differentiation. In this study we use near-infrared spectroscopy (NIRS) to detect functional changes, across relatively large cortical cell populations, simultaneously from prefrontal and posterior parietal cortices. Imaging data... |

| The invariance of some system properties over a range of temporal and/or spatial scales is an attribute of many processes in nature1, often characterised by power law functions and fractal geometry2. In particular, there is growing consensus in that fat-tailed functions like the power law adequately describe long-distance dispersal (LDD) spread of organisms 3,4. Here we show that the spatial spread of individuals governed by a power law dispersal function is represented by a clear and unique signature, characterised by two properties: A fractal geometry of the boundaries of patches generated by dispersal with a fractal dimension D displaying universal features, and a disrupted patch size distribution characterised by two different power laws.

| Using modern TV-endoscope equipment, we have experimented image processing in several ways. This time, we designed new image processing unit called “Color Subtracted Enhancement image processing unit”. This unit　was made by combining the RGB-Subtraction　image processing device with the color enhancement image processing device. The　RGB-subtraction device is an analogue unit that　enables us to remove the visible red, green and blue peaks from the image. We can subtract the images R-G, R-B, G-R, B-R, B-G simply by changing the switches. The color enhancement device (developed by Olympus optical corporation inc.) is a digital processing unit that lets us reinforce any of these colors. This... |
