The objective of the present study was to compare genetic and phenotypic variation of 103 Saccharomyces cerevisiae strains isolated from winemaking environments. We used bioinformatics approaches to identify genetically similary strains with specific phenotypes and to estimate a strain's biotechnological potential. 
A S. cerevisiae collection, comprising 440 strains that were obtained from winemaking environments in Portugal has been constituted during the last years. All strains were genetically characterized by a set of eleven highly polymorphic microsatellites and showed unique allelic combinations. Using neural networks, a subset of 103 genetically most diverse strains was chosen for phenotypic analysis, that included growth... |

Simultaneous overexpression or underexpression of multiple genes, used in various forms as probes in the high-throughput microarray experiments, facilitates the identification of their underlying functional proximity. This kind of functional associativity (or conversely the separability) between the genes can be represented proficiently using co-expression networks. The extensive repository of diversified microarray data encounters a recent problem of multi-experimental data integration for the aforesaid purpose. This paper highlights a novel integration method of gene co-expression networks, based on the search for their consensus network, derived from diverse microarray experimental data for the purpose of clustering. The proposed methodology avoids the... |

Openness at the layer of cultural works and data is the key to the data infrastructure we need to accelerate science. This article lays out three key elements of data infrastructure - collaboration, classification, and openness - which draw us inevitably towards the long-claimed, but rarely-achieved, goal of the scientific method: to make claims that are reproducible under similar circumstances by someone other than the claimant, to be reproducible. |

UniProtKB provides the scientific community with a comprehensive collection of protein sequence records containing extensive curated information including functional and sequence annotation. This information is derived from a variety of sources such as scientific literature and sequence analysis programs as well as data imported from automatic annotation systems and external databases. To allow users to ascertain the origin of each data item in a UniProtKB record, an evidence attribution system is being introduced which links each piece of information to its original source. This system allows users to trace the origin of all information, to differentiate easily between experimental and computational data, and to assess data reliability. The current system... |

Interpretation of allelic copy measurements at polymorphic markers in cancer samples presents distinctive challenges and opportunities. Due to frequent gross chromosomal alterations occurring in cancer (aneuploidy), many genomic regions are present at homologous-allele imbalance. Within such regions, the unequal contribution of alleles at heterozygous markers allows for direct phasing of the haplotype derived from each individual parent. In addition, genome-wide estimates of homologue specific copy- ratios (HSCRs) are important for interpretation of the cancer genome in terms of fixed integral copy-numbers. We describe HAPSEG, a probabilistic method to interpret bi- allelic marker data in cancer samples. HAPSEG operates by partitioning the genome into... |

Polyhedral forms are extremely widespread both in animate and inanimate nature. Thus, crystals occur as polyhedra only. Besides, these forms are quite common with various primitive organisms, i.e. icosahedral viruses, radiolaria and algae. Here we discuss the cases of exotic Boxfish and Porcupinefish. The specific morphology of the Boxfish reveals in polygonal osseous blades, covering its body. As for the Porcupinefish, its polyhedral approximation was observed via certain geometrical techniques applied. Namely, their spine bases were considered the Delaunay point (R, r)-systems. Consequently, the respective Dirichlet tiling proved to be quasifullerenes and analogous to the Boxfish morphology. This unexpected geometrical dualism of the two families... |

We define phosphovariants as genetic variations that change phosphorylation sites or their interacting kinases. Considering the essential role of phosphorylation in protein functions, it is highly likely that phosphovariants change protein functions and may constitute a proportion of the mechanisms by which genetic variations cause individual differences or diseases. We categorized phosphovariants into three subtypes and developed a system that predicts them. Our method can be used to screen important polymorphisms and help to identify the mechanisms of genetic diseases. |

Results from multivariate molecular biological experiments become increasingly complex. Hence, the challenge of projecting high-dimensional data onto few dimensions for effective data visualization is becoming increasingly important in Systems Biology. Effective data visualization can summarize the activity of many variables over time as well as display relationships between variables. Dynamic interactive visualization tools can provide scientists with ways of visually identifying relationship and patterns, and improve communication of results on the web and in presentations. For this, interactive systems with animation have great potential since they add dimensions to static images limited to two dimensions. Interactivity and animation is particularly... |

The fact that all living organisms are related by common descent is one of the central principles of modern biology. Since the early 1990's the amount of data available to evolutionary biologists has exploded, and Elsevier’s journal _Molecular Phylogenetics and Evolution_, has become the largest single publisher of evolutionary trees (phylogenies). These trees and their supporting data potentially form a tremendous resource for biologists, with applications in genomics, evolutionary biology, biodiversity, and public health. However, most published trees are not available in any public database, but instead languish as images, "locked up" in the pages of journals. A long term solution to this problem is to invert the... |

The emergence of tuberculosis resistant to multiple, first- and second-line antibiotics poses challenges to a global control strategy that relies on standard drug treatment regimens. The high drug-resistant strains of Mycobacterium tuberculosis (Mtb) have been implicated in outbreaks and have been found throughout the world; a comprehensive understanding, the magnitude of this threat requires an accurate assessment of the worldwide burden of resistance. In an attempt to design anti-TB drugs, the target chosen is a key enzyme of Mtb, O-Succinylbenzoate synthase (OSBS), which is an attractive target for its role in electron transport chain as OSBS is not available in humans. An attempt has been to built the 3-D structure of Mtb-OSBS using online Swiss model... |

The soybean-derived products are among the most important agricultural products in the USA and the world. Conventional analytical methods for soybean composition analysis are both time consuming and costly. Faster and less expensive methods are required for most practical applications. To improve the accuracy, reliability and sensitivity of NIR, major advancements in instrumentation, as well as, data analysis / calibration methodology are required. Novel NIR instruments, such as DA-NIR and FT-NIR spectrometers developed in recent years have the potential for improving significantly the quantification of soybean composition at a reasonable cost. We present representative calibrations and data for intact soybean composition analysis obtained at the... |

OBJECTIVE: To evaluate the association between having a household member with a cancer-related limitation (physical, mental, or emotional) and human papillomavirus (HPV) vaccine uptake among females aged 9 – 17 years. 
METHODS: We analyzed 2008 National Health Interview Survey for our cross-sectional analysis. All households with females aged 9 – 17 years were eligible for inclusion in our analysis. Our outcomes of interest included HPV vaccine initiation (≥1 dose) and series completion (full 3 doses). A dichotomous variable indicating a cancer-related limitation for a household member was created if at least one adult in the household responded to having a limitation caused by cancer. We used... |

The construction of complex statial simulation models such as those used in network epidemiology, is a daunting task due to the large amount of data involved in their parameterization. Such data, which frequently resides on large geo-referenced databases, has to be processed and assigned to the various components of the model. All this just to construct the model, then it still has to be simulated and analyzed under different epidemiological scenarios. This workflow can only be achieved efficiently by computational tools that can automate most if not all these time-consuming tasks. In this paper, we present a simulation software, Epigrass, aimed to help designing and simulating network-epidemic models with any kind of node behavior.

With the thousands of scientific papers being produced every month, picking an authors name, associate it to a research field and right evaluate his or her performance is in most of times a cumbersome task. I am proposing here that science indexes as h-index, g-index, total citations and published papers could be added to biomedical bibliographic citation in order to create a unique identifier for a given researcher. |

Standard graphical representations have played a crucial role in science and engineering throughout the last century. Without electrical symbolism, it is very likely that our industrial society would not have evolved at the same pace. Similarly, specialized notations such as the Feynmann notation or the process flow diagrams did a lot for the adoption of concepts in their own fields. With the advent of Systems Biology, and more recently of Synthetic Biology, the need for precise and unambiguous descriptions of biochemical interactions has become more pressing. While some ideas have been advanced over the last decade, with a few detailed proposals, no actual community standard has emerged. The Systems Biology Graphical Notation (SBGN) is a graphical... |
