Oil Extraction Infrastructure Development And Resulting Land-Cover Change In Mckenzie County, North Dakota, 2009 To 2014
Improved techniques and methods in directional drilling and hydraulic fracturing have allowed once inaccessible resources to become profitably accessible in the Bakken Region of North Dakota (Fershee 2011). This recent development has been rapid, and associated land-cover change can be described as spatially extensive (Baker et al. 2012). After an extensive literature review and to the best of my knowledge, little research has been conducted in the Bakken Region regarding land-cover change associated with oil development. Using high-spatial-resolution, four-band imagery from the National Agriculture Imagery Program (NAIP) in conjunction with Geographic Object-Based Image Analysis (GEOBIA) techniques, it is possible to identify narrow-linear and small-area features on the landscape associated with oil development.
The overall accuracy for McKenzie County was 41.2 percent, significantly lower than overall accuracies seen in similar studies. These results suggest this method is not entirely suitable for land-cover change analysis in the grassland biome without additional data analysis and/or editing. Further analysis of a selected smaller portion of the county displaying land-cover characteristics amenable for accurate classification found oil extraction infrastructure contributed to an expected but minimal decrease in grassland and agricultural land-cover
Design, development and deployment of a software platform for real-time reporting in the west of Scotland demersal fleet : FIS032
Acknowledgements We thank the co-funders (FIS, SFO, Scottish White Fish Producers Association, Seafish and the University of Aberdeen), the participating POs and the participating fishers for being willing to take a chance on RTR. Critical early support was given by D. Anderson (Aberdeen Fish Producers Organisation) and M. Park (SWFPA). K. Haflinger (Sea State Inc., Seattle, USA) generously shared valuable insights about the use of RTR on the west coast. C. Asare is thanked for his concerted efforts trying to âcatchâ fishers to be interviewed in 2019. C. Needle (Marine Scotland Science) kick-started interest in mapping unwanted catch of juvenile cod in the North Sea.Publisher PD
Behcet disease (BD) and BD-like clinical phenotypes : NF-kappa B pathway in mucosal ulcerating diseases
Behcet's disease (BD) is a heterogeneous multi-organ disorder in search of a unified pathophysiological theory and classification. The disease frequently has overlapping features resembling other disease clusters, such as vasculitides, spondyloarthritides and thrombophilias with similar genetic risk variants, namelyHLA-B*51,ERAP1,IL-10,IL-23R. Many of the BD manifestations, such as unprovoked recurrent episodes of inflammation and increased expression of IL-1, IL-6 and TNF alpha, overlap with those of the hereditary monogenic autoinflammatory syndromes, positioning BD at the crossroads between autoimmune and autoinflammatory syndromes. BD-like disease associates with various inborn errors of immunity, including familial Mediterranean fever, conditions related to dysregulated NF-kappa B activation (egTNFAIP3,NFKB1,OTULIN,RELA,IKBKG) and either constitutional trisomy 8 or acquired trisomy 8 in myelodysplastic syndromes. We review here the recent advances in the immunopathology of BD, BD-like diseases and the NF-kappa B pathway suggesting new elements in the elusive BD etiopathogenesis.Peer reviewe

Human Inborn Errors of Immunity: 2019 Update on the Classification from the International Union of Immunological Societies Expert Committee.
We report the updated classification of Inborn Errors of Immunity/Primary Immunodeficiencies, compiled by the International Union of Immunological Societies Expert Committee. This report documents the key clinical and laboratory features of 430 inborn errors of immunity, including 64 gene defects that have either been discovered in the past 2Â years since the previous update (published January 2018) or were characterized earlier but have since been confirmed or expanded upon in subsequent studies. The application of next-generation sequencing continues to expedite the rapid identification of novel gene defects, rare or common; broaden the immunological and clinical phenotypes of conditions arising from known gene defects and even known variants; and implement gene-specific therapies. These advances are contributing to greater understanding of the molecular, cellular, and immunological mechanisms of disease, thereby enhancing immunological knowledge while improving the management of patients and their families. This report serves as a valuable resource for the molecular diagnosis of individuals with heritable immunological disorders and also for the scientific dissection of cellular and molecular mechanisms underlying inborn errors of immunity and related human diseases

Human Inborn Errors of Immunity: 2019 Update of the IUIS Phenotypical Classification.
Since 2013, the International Union of Immunological Societies (IUIS) expert committee (EC) on Inborn Errors of Immunity (IEI) has published an updated phenotypic classification of IEI, which accompanies and complements their genotypic classification into ten tables. This phenotypic classification is user-friendly and serves as a resource for clinicians at the bedside. There are now 430 single-gene IEI underlying phenotypes as diverse as infection, malignancy, allergy, autoimmunity, and autoinflammation. We herein report the 2019 phenotypic classification, including the 65 new conditions. The diagnostic algorithms are based on clinical and laboratory phenotypes for each of the ten broad categories of IEI
Incorporating scale dependence in disease burden estimates:the case of human African trypanosomiasis in Uganda
The WHO has established the disability-adjusted life year (DALY) as a metric for measuring the burden of human disease and injury globally. However, most DALY estimates have been calculated as national totals. We mapped spatial variation in the burden of human African trypanosomiasis (HAT) in Uganda for the years 2000-2009. This represents the first geographically delimited estimation of HAT disease burden at the sub-country scale.Disability-adjusted life-year (DALY) totals for HAT were estimated based on modelled age and mortality distributions, mapped using Geographic Information Systems (GIS) software, and summarised by parish and district. While the national total burden of HAT is low relative to other conditions, high-impact districts in Uganda had DALY rates comparable to the national burden rates for major infectious diseases. The calculated average national DALY rate for 2000-2009 was 486.3 DALYs/100 000 persons/year, whereas three districts afflicted by rhodesiense HAT in southeastern Uganda had burden rates above 5000 DALYs/100 000 persons/year, comparable to national GBD 2004 average burden rates for malaria and HIV/AIDS.These results provide updated and improved estimates of HAT burden across Uganda, taking into account sensitivity to under-reporting. Our results highlight the critical importance of spatial scale in disease burden analyses. National aggregations of disease burden have resulted in an implied bias against highly focal diseases for which geographically targeted interventions may be feasible and cost-effective. This has significant implications for the use of DALY estimates to prioritize disease interventions and inform cost-benefit analyses

The Ever-Increasing Array of Novel Inborn Errors of Immunity : an Interim Update by the IUIS Committee
The most recent updated classification of inborn errors of immunity/primary immunodeficiencies, compiled by the International Union of Immunological Societies Expert Committee, was published in January 2020. Within days of completing this report, it was already out of date, evidenced by the frequent publication of genetic variants proposed to cause novel inborn errors of immunity. As the next formal report from the IUIS Expert Committee will not be published until 2022, we felt it important to provide the community with a brief update of recent contributions to the field of inborn errors of immunity. Herein, we highlight studies that have identified 26 additional monogenic gene defects that reach the threshold to represent novel causes of immune defects.Peer reviewe
