| The Crop Research Institute, Dept. of Vegetables and Special Crops in Olomouc is responsible for the conservation and documentation of genetic resources of vegetable, medicinal, aromatic, and spice plants. Collections maintained by the department in Olomouc include more than 10,000 accessions of about 430 botanical species and the collection of cucurbitaceous genetic resources with 1,713 accessions potentially available is one of the largest. Unfortunately only about 40 % of them is already regenerated. The collection is distributed in 11 species and the biggest part of collection shapes Cucumis sativus L. and Cucurbita sp. |

| BioModels Database ("http://www.ebi.ac.uk/biomodels/":http://www.ebi.ac.uk/biomodels/) is a free resource for storing, viewing and retrieving published, peer-reviewed, quantitative models of biochemical and cellular systems. As a storage format, BioModels Database uses the Systems Biology Markup Language (SBML), but also allows submission and export of models in various other commonly used formats.

To offer scientists reliable information, models are curated to comply with the MIRIAM (Minimal Information Requested In the Annotation of biochemical Models) standard. This curation process involves verification of the model structure, the parameter and variable values and its mathematical relations.... |

| NISEED (Network for In situ Expression and Embryological Data) is a generic infrastructure for the creation, maintenance and integration of molecular and anatomical information on model organisms. We applied it to ascidians which are marine invertebrate chordates. These animals constitute model organisms of choice for developmental biology because their embryos develop with a small number of cells and an invariant lineage, allowing their study with a cellular level of resolution. In ANISEED (Ascidian NISEED), embryogenesis of ascidian is represented at the level of the genome via functional gene annotations, cis-regulatory elements or gene expression data, at the level of the cell by representing its morphology, fates, lineage, and relations with its... |

| Identifying agents that inhibit the proliferation of cancer stem cells is of great importance in cancer biology. Curcumin has been shown to function as an anti-cancer agent. One of the tumor suppressors that appear to be induced in response to curcumin treatment is p53. A recent study suggests that curcumin increases the expression of miRNAs, such as miR-22, miR-181a, b, c, miR-34, miR-103, and miR-21. Intriguingly, miR-34, 181b, c, miR-103, miR-21, and miR-24 have been identified as transcriptional targets of the tumor suppressor p53. This data suggests a possibility that curcumin, by inducing the expression of p53, it could increase the expression of these microRNAs. A number of groups have shown that c-Myc, Sox-2, Klf-4, Oct-4, Sox-2, Nanog, and... |

| Integration of neurotransmitter and neuromodulator signals in the striatum plays a central role in the functions and dysfunctions of the basal ganglia. DARPP-32 is a key actor of this integration in the GABAergic medium-size spiny neurons, in particular in response to dopamine and glutamate. When phosphorylated by cAMP-dependent protein kinase (PKA) DARPP-32 inhibits protein phosphatase-1 (PP1), whereas when phosphorylated by cyclin-dependent kinase 5 (CDK5) it inhibits PKA. DARPP-32 is also regulated by casein kinases and by several protein phosphatases. These complex and intricate regulations make simple predictions of DARPP-32 dynamic behaviour virtually impossible. We used detailed quantitative modelling of the regulation of DARPP-32 phosphorylation to... |

| Consistent attribution of research data upon reuse is necessary to reward the original data-producing investigators, reconstruct provenance, and inform data sharing policies, tool requirements, and funding decisions. Unfortunately, norms for data attribution are varied and often weak. As part of the DataONE 2010 summer internship program, three interns studied the policies, practice, and implications of current data attribution behavior in the environmental sciences. We found that few policies recommend robust data citation practices: in our preliminary evaluation, only one-third of repositories (n=26), 6% of journals (n=307), and 1 of 53 funders suggested a best practice for data citation. We manually reviewed 500 papers published between 2000 and... |

| Massively parallel sequencers become widespread and produce unprecedented amounts of sequence reads in many biological fields. DNA Data Bank of Japan (DDBJ) has constructed the international sequence database collaboration (INSDC) together with EBI and NCBI. In 2008, DDBJ has established the DDBJ Read Archive (DRA) to archive raw output data from the new sequencing platforms. DRA archives and provides the raw data sets together with the other two INSDC partners the Sequence Read Archive (SRA) at NCBI and the European Sequence Read Archive (ERA) at EBI. These new sequencing platforms are also used to count DNA/RNA molecules instead of microarray experiment because of their higher accuracy. Since 2004, DDBJ has operated CIBEX as a repository database for... |

| Seagrasses provide habitat for a wide variety of aquatic species, and reduce coastal erosion via sediment stabilization. The areal coverage of seagrass beds on the Mississippi barrier islands appears to have declined substantially since the 1960s. However, difficulties in sampling benthic vegetation, differences among previous studies in survey methods, and a lack of data on year-to-year variation in coverage have impeded quantitative study of this decline. Thus, the goal of the present study was to utilize historical remote sensing data to quantitatively determine changes in seagrass (predominantly Halodule wrightii Ascherson) coverage on the Mississippi barrier islands. Analyses were limited to imagery acquired during late summer through autumn, when... |

| The superfamily of serine proteinase inhibitors (serpins) is involved in wide arrays of fundamental biological processes such as blood coagulation, complement activation, fibrinolysis, angiogenesis, inflammation and tumor suppression. The average protein size of a serpin family member is 350-400 amino acids, but gene structure varies in terms of number and position of exons and introns. All known serpins can be grouped into 16 clades and 10 orphan sequences. Vertebrate serpins can be conveniently classified into six sub-groups, based on three independent biological features - genomic organization, diagnostic amino acid sites and rare indels.
The objective of this study was to elucidate the phylogenetic kinships of serpins involved in... |

| Classifying biological sequences is one of the most important tasks in computational biology. In the last decade, support vector machines (SVMs) in combination with sequence kernels have emerged as a de-facto standard. These methods are theoretically well-founded, reliable, and provide high-accuracy solutions at low computational cost. However, obtaining a highly accurate classifier is rarely the end of the story in many practical situations. Instead, one often aims to acquire biological knowledge about the principles underlying a given classification task. SVMs with traditional sequence kernels do not offer a straightforward way of accessing this knowledge.

In this contribution, we propose a new approach to analyzing... |

| 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. |

| Understanding the nature of the relationship between demographic vital rates and the rate of population change (λ) is important for determining effective strategies for population management and conservation. We examined the relative impacts of various demographic vital rates on λ within the range of temporal vital rate variability observed in a harvested population to test the hypotheses that adult survival rates in ungulates are relatively invariant when compared to other vital rates and that variability in calf survival has a greater influence on rates of population change than adult survival. Vital rates were estimated for an elk (_Cervus elaphus_) population at Fort Riley, Kansas from October 2003 – February 2007. The... |

| a)	Background/Question/Methods
Watersheds have a profound capacity to retain and remove nitrogen (N) inputs before entering coastal waters thereby minimizing eutrophication and hypoxia in estuarine waters. Research suggests that much of this N cycling occurs within aquatic ecosystems, e.g., lakes, streams and wetlands, which may become “hotspots” of nitrous oxide (N2O) production. We examined the effects of woody debris on nitrate removal and denitrification rates in streams of different N enrichment levels. Three different standardized substrates (fresh wood blocks, bundles of naturally occurring streambed wood, and clay‐fired blocks) that were expected to vary in their pool of labile carbon were... |

| Directive 2001/18 EC demands the cultivation of genetically modified organisms (GMO) to be accompanied by post-market environmental monitoring (PMEM). It is composed of a general surveillance for unanticipated adverse effects and case specific monitoring (CSM), which is set up to reduce substantial uncertainties in relevant risk scenarios identified in the environmental risk assessment. PMEM should also allow early identification of potential long-term effects of cultivating GMOs. It should facilitate decisions in risk management.
In this project, a method for a Europe-wide CSM was to be developed. Starting with critical questions from ERA, exposure scenarios (first for non target organisms, later for all other partitions of the ERA) were... |

| Protein kinases are clinically relevant and attractive drug targets for most of the cancerous diseases. Ribosomal protein s6 kinase (P70s6 kinase) is a mitogen activated Ser/Thr protein kinase, essential for cell growth, G1 cell cycle progression and cell survival. Human P70s6 kinase is involved in different signaling pathways and phosphorylates the downstream S6 protein of the 40S ribosomal subunit there by controlling the translational activity. Over expression of human P70s6 or rapid amplification of gene (RPS6KB1) leads to rapid cell proliferation causing cancer in various organs of humans like colon, breast, ovary, etc. The over expression is principally due to activation of some phosphorylating sites or ATP binding sites in the domain regions. In the... |
