A Preliminary Report on the Frequency of Scrapie Susceptibility Alleles in Hampshire Sheep

Blood samples were collected from a total of 201 animals in five purebred Hampshire sheep flocks. DNA was isolated from the samples, and the protein-coding region of the prion protein gene was amplified using the polymerase chain reaction. The allelic frequencies of the prion protein codons 171 and 136 were determined. Results revealed that the codon 171 alleles Q, R, and H were present at frequencies of 72%, 27% and 1%, respectively. A subset of samples (n=48) was randomly selected for codon 136 genotyping. The codon 136 V allele, an allele not frequently observed in Suffolk sheep, was present in animals from three of five flocks at a frequency ranging from 7 to 33% of the animals tested within each flock. These data comprise the first report on the prevalence of scrapie susceptibility alleles in Hampshire sheep

Does practice analysis agree with the ambulatory care sensitive conditions list of avoidable unplanned admissions: cross-sectional study in the East of England.

Objectives: To use Significant Event Audits (SEA) in primary care to determine which of a sample of emergency (unplanned) admissions were potentially avoidable; and compare to the NHS list of ambulatory care sensitive conditions (ACSCs). Design: Analysis of unplanned medical admissions randomly identified in secondary care. Setting: Primary Care in the East of England. Participants: 20 general practice teams trained to use SEA on unplanned admissions to identify potentially preventable factors. Interventions: SEA of admissions. Main outcome measures: Level of agreement between those admissions identified as potentially preventable by SEA and the NHS ACSC list. Results: 132 (26%) of randomly selected patients with unplanned admissions gave consent and an SEA was performed by their primary practice team. 130 SEA reports had sufficient data for our analysis. Practices concluded that 17 (13%) of admissions were potentially preventable. The NHS ACSC list identified 36 admissions (28%) as potentially preventable. There was a low level of agreement between the practices and the NHS list as to which admissions were preventable (Kappa = 0.253). The ACSC list consisted mainly of respiratory admissions whereas the practice list identified a wider range of cases and identified context-specific factors as important. Conclusions: There was disagreement between the NHS list and practice conclusions of potentially avoidable admissions. The SEAs suggest that the pathway into unplanned admission may be less dependent on the condition than on context-specific factors, and the assumption that unplanned admissions for ACSC conditions are reasonable indicators of performance for primary care may not be valid

Introduction and evolution of dengue virus type 2 in Pakistan: a phylogeographic analysis

Discrete Bayes Factors from SPREAD. Locations are denoted with two letter codes (Additional file 5: Table S3). The upper half of the matrix shows the mean (standard deviation) for the discrete Bayes Factor calculated for the 12 discrete trait models. The lower half of the matrix shows how many times a linkage had a Bayes Factor greater than 3.0. (XLSX 9 kb

Assessment of occupational noise-induced hearing loss for ACC: A practical guide for otolaryngologists

Several people have shared their expertise and support in developing this guideline. The first version was developed and published in 2011. ACC, occupational medicine specialists and otorhinolaryngologists (ORLs) collaborated to provide practical guidance on how to assess whether noised-induced hearing loss (NIHL) was caused by occupational exposure. ACC’s Audiology Advisor requested that the 2011 guideline be updated. We convened an expert advisory group and, alongside evidence-based research updated since 2011, provided expert consensus knowledge in this area. This 2018 version of the guideline is now presented to you to inform your specialist assessments of ACC ONIHL clients. The New Zealand Society of Otolaryngology, Head and Neck Surgery endorsed the guideline on 5 October 2018.The guideline includes summaries of ACC-commissioned systematic literature reviews on key aspects of ONIHL, and references to resources to assist you to provide robust, evidence- based reports. Background information on relevant legislation and specific details of the New Zealand context, including useful guidance on carrying out assessments for third parties, are also included.

The SPARC Toroidal Field Model Coil Program

The SPARC Toroidal Field Model Coil (TFMC) Program was a three-year effort between 2018 and 2021 that developed novel Rare Earth Yttrium Barium Copper Oxide (REBCO) superconductor technologies and then successfully utilized these technologies to design, build, and test a first-in-class, high-field (~20 T), representative-scale (~3 m) superconducting toroidal field coil. With the principal objective of demonstrating mature, large-scale, REBCO magnets, the project was executed jointly by the MIT Plasma Science and Fusion Center (PSFC) and Commonwealth Fusion Systems (CFS). The TFMC achieved its programmatic goal of experimentally demonstrating a large-scale high-field REBCO magnet, achieving 20.1 T peak field-on-conductor with 40.5 kA of terminal current, 815 kN/m of Lorentz loading on the REBCO stacks, and almost 1 GPa of mechanical stress accommodated by the structural case. Fifteen internal demountable pancake-to-pancake joints operated in the 0.5 to 2.0 nOhm range at 20 K and in magnetic fields up to 12 T. The DC and AC electromagnetic performance of the magnet, predicted by new advances in high-fidelity computational models, was confirmed in two test campaigns while the massively parallel, single-pass, pressure-vessel style coolant scheme capable of large heat removal was validated. The REBCO current lead and feeder system was experimentally qualified up to 50 kA, and the crycooler based cryogenic system provided 600 W of cooling power at 20 K with mass flow rates up to 70 g/s at a maximum design pressure of 20 bar-a for the test campaigns. Finally, the feasibility of using passive, self-protection against a quench in a fusion-scale NI TF coil was experimentally assessed with an intentional open-circuit quench at 31.5 kA terminal current.Comment: 17 pages 9 figures, overview paper and the first of a six-part series of papers covering the TFMC Progra
