The Future of eDiscovery in Tennessee

This Article begins by outlining changes in the modern digital world through an examination of essential laws of computing unfamiliar to most lawyers but crucial to an understanding of the changing landscape of technology and its projected impact on modern society. Part II then applies these principles to the practice of law in the context of electronic discovery, pointing to the challenges posed under the current Rules of Civil Procedure, an ever-increasing overabundance of discoverable data, and the inadequacy of existing technology and processes possessed by the typical lawyer to deal with these challenges. Finally, Part III of this Article will examine and advocate for the adoption of the proposed changes to the Federal Rules of Civil Procedure, as well as adoption of similar provisions in Tennessee, and ultimately offer suggestions to reform eDiscovery through process improvement, collaboration, and technology implementation

Herein we report the results from implementing a novel, hybrid Sanger/454-based BAC-pool sequencing strategy using minimum tiling path (MTP) BACs from Ctg-3301 and Ctg-465, two large genomic segments in A12 and D12 homoeologous chromosomes (Ctg). To enable generation of longer contig sequences in assembly, we implemented a hybrid assembly method to process ~35x data from 454 technology and 2.8-3x data from Sanger method. Hybrid assemblies offered higher sequence coverage and better sequence assemblies. Homology studies revealed the presence of retrotransposon regions like Copia and Gypsy elements in these contigs and also helped in identifying new genomic SSRs. Unigenes were anchored to the sequences in Ctg-3301 and Ctg-465 to support the physical map. Gene density, gene structure and protein sequence information derived from protein prediction programs were used to obtain the functional annotation of these genes. Comparative analysis of both contigs with Arabidopsis genome exhibited synteny and microcollinearity with a conserved gene order in both genomes. This study provides insight about use of MTP-based BAC-pool sequencing approach for sequencing complex polyploid genomes with limited constraints in generating better sequence assemblies to build reference scaffold sequences. Combining the utilities of MTP-based BAC-pool sequencing with current longer and short read NGS technologies in multiplexed format would provide a new direction to cost-effectively and precisely sequence complex plant genomes.Yeshttp://www.plosone.org/static/editorial#pee

Genomic Sequence around Butterfly Wing Development Genes: Annotation and Comparative Analysis

, where a whole-genome BAC library allows targeted access to large genomic regions. genes. Comparative analysis with orthologous regions of the lepidopteran reference genome allowed assessment of conservation of fine-scale synteny (with detection of new inversions and translocations) and of DNA sequence (with detection of high levels of conservation of non-coding regions around some, but not all, developmental genes)., both involved in multiple developmental processes including wing pattern formation

Biomarkers of Nutrition for Development (BOND)—Iron Review

This is the fifth in the series of reviews developed as part of the Biomarkers of Nutrition for Development (BOND) program. The BOND Iron Expert Panel (I-EP) reviewed the extant knowledge regarding iron biology, public health implications, and the relative usefulness of currently available biomarkers of iron status from deficiency to overload. Approaches to assessing intake, including bioavailability, are also covered. The report also covers technical and laboratory considerations for the use of available biomarkers of iron status, and concludes with a description of research priorities along with a brief discussion of new biomarkers with potential for use across the spectrum of activities related to the study of iron in human health. The I-EP concluded that current iron biomarkers are reliable for accurately assessing many aspects of iron nutrition. However, a clear distinction is made between the relative strengths of biomarkers to assess hematological consequences of iron deficiency versus other putative functional outcomes, particularly the relationship between maternal and fetal iron status during pregnancy, birth outcomes, and infant cognitive, motor and emotional development. The I-EP also highlighted the importance of considering the confounding effects of inflammation and infection on the interpretation of iron biomarker results, as well as the impact of life stage. Finally, alternative approaches to the evaluation of the risk for nutritional iron overload at the population level are presented, because the currently designated upper limits for the biomarker generally employed (serum ferritin) may not differentiate between true iron overload and the effects of subclinical inflammation

Iron Behaving Badly: Inappropriate Iron Chelation as a Major Contributor to the Aetiology of Vascular and Other Progressive Inflammatory and Degenerative Diseases

The production of peroxide and superoxide is an inevitable consequence of aerobic metabolism, and while these particular "reactive oxygen species" (ROSs) can exhibit a number of biological effects, they are not of themselves excessively reactive and thus they are not especially damaging at physiological concentrations. However, their reactions with poorly liganded iron species can lead to the catalytic production of the very reactive and dangerous hydroxyl radical, which is exceptionally damaging, and a major cause of chronic inflammation. We review the considerable and wide-ranging evidence for the involvement of this combination of (su)peroxide and poorly liganded iron in a large number of physiological and indeed pathological processes and inflammatory disorders, especially those involving the progressive degradation of cellular and organismal performance. These diseases share a great many similarities and thus might be considered to have a common cause (i.e. iron-catalysed free radical and especially hydroxyl radical generation). The studies reviewed include those focused on a series of cardiovascular, metabolic and neurological diseases, where iron can be found at the sites of plaques and lesions, as well as studies showing the significance of iron to aging and longevity. The effective chelation of iron by natural or synthetic ligands is thus of major physiological (and potentially therapeutic) importance. As systems properties, we need to recognise that physiological observables have multiple molecular causes, and studying them in isolation leads to inconsistent patterns of apparent causality when it is the simultaneous combination of multiple factors that is responsible. This explains, for instance, the decidedly mixed effects of antioxidants that have been observed, etc...Comment: 159 pages, including 9 Figs and 2184 reference

Plasma hepcidin concentrations significantly predict interindividual variation in iron absorption in healthy men

Background: Iron absorption is proposed to be regulated by circulating hepcidin, but, to date, little data are available to evaluate this relation in humans. Objective: Stored samples from a human iron absorption study were used to test the hypothesis that differences in plasma hepcidin explain interindividual variation in iron absorption. Design: Hepcidin-25 concentrations were measured in fasting samples from men aged ≥40 y (n = 33) recruited to a study investigating the relation between the HFE genotype, iron absorption, and iron status. Results: Log iron absorption was negatively correlated with serum ferritin (r = −0.59, P < 0.001) and with plasma hepcidin (r = −0.55, P < 0.001) but was unaffected by genotype. There was a positive correlation (r = 0.82, P < 0.001) between hepcidin (mean: 2.3; range: 0.1–7.8 nmol/L) and ferritin (mean: 70; range: 9–208 μg/L). Multiple linear regression models showed that plasma hepcidin in isolation significantly predicted 36% of the interindividual variation in iron absorption. Conclusions: Plasma hepcidin and serum ferritin concentrations are highly correlated, and, in the normal range of plasma hepcidin values, 36% of interindividual differences in iron absorption are explained by differences in circulating plasma hepcidin
