The role of cranial and thoracic EMG within diagnostic criteria for ALS.

INTRODUCTION: The contribution of cranial and thoracic region electromyography (EMG) to diagnostic criteria for amyotrophic lateral sclerosis (ALS) has not been evaluated. METHODS: Clinical and EMG data from each craniospinal region were retrospectively assessed in 470 patients; 214 had ALS. Changes to diagnostic classification in Awaji-Shima and revised El Escorial criteria following withdrawal of cranial/thoracic EMG data were ascertained. RESULTS: Sensitivity for lower motor neuron involvement in ALS was highest in cervical/lumbar regions; specificity was highest in cranial/thoracic regions. Cranial EMG contributed to definite/probable Awaji-Shima categorization in 1.4% of patients. Thoracic EMG made no contribution. For revised El Escorial criteria, cranial and thoracic data reclassified 1% and 5% of patients, respectively. CONCLUSION: Cranial EMG data make small contributions to both criteria, thoracic data contribute only to the revised El Escorial criteria. However, cranial and thoracic region abnormalities are specific in ALS. Consideration should be given to allowing greater diagnostic contribution from thoracic EMG

Assessment of bovine hoof conformation and its association with lameness, animal factors and management practices on small-scale dairy farms in Kiambu district, Kenya

Digital health and conformation were assessed in 216 dairy cattle on 78 randomly selected small-scale farms. For each cow, gait was assessed and the digits examined in detail. Hoof measurements (angle and length of the dorsal hoof wall, heel depth and hoof-base area) were also made. Hoof measurements varied most between individual cattle. Dorsal angle was correlated with heel depth (r = 0,53; P = 0,001) and dorsal length (r = -0,40; P = 0,001). The hoof-base area was correlated with the dorsal length (r = 0,41; P = 0,001). There were significant breed differences in dorsal angle (P = 0,03) and dorsal length (P < 0,01). The dorsal angle was correlated with parity and body condition, while the dorsal length, heel depth and the hoof-base area were correlated with the heart girth (P< 0,01). Hoof conformation was associated with both clinical lameness and hoof lesions. A 1cm increase in the dorsal length increased the odds of lameness by 16,9, heel erosion by 1,8, underrunning by 5,4 and overgrowth by 40 (P < 0,01).The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Classtalk: A Classroom Communication System for Active Learning

This pdf file is an article describing the advantages of using Classtalk technology in the classroom to enhance classroom communication. Classtalk technology cab facilitate the presentation of questions for small group work, collec the student answers and then display histograms showing how the class answered. This new communication technology can help instructors create a more interactive, student centered classroom, especially when teaching large courses. The article describes Classtalk as a very useful tool not only for engaging students in active learning, but also for enhancing the overall communication within the classroom. This article is a selection from the electronic Journal for Computing in Higher Education. Educational levels: Graduate or professional

Growing Environmental Activists: Developing Environmental Agency and Engagement Through Children’s Fiction.

We explore how story has the potential to encourage environmental engagement and a sense of agency provided that critical discussion takes place. We illuminate this with reference to the philosophies of John Macmurray on personal agency and social relations; of John Dewey on the primacy of experience for philosophy; and of Paul Ricoeur on hermeneutics, dialogue, dialectics and narrative. We view the use of fiction for environmental understanding as hermeneutic, a form of conceptualising place which interprets experience and perception. The four writers for young people discussed are Ernest Thompson Seton, Kenneth Grahame, Michelle Paver and Philip Pullman. We develop the concept of critical dialogue, and link this to Crick's demand for active democratic citizenship. We illustrate the educational potential for environmental discussions based on literature leading to deeper understanding of place and environment, encouraging the belief in young people that they can be and become agents for change. We develop from Zimbardo the key concept of heroic resister to encourage young people to overcome peer pressure. We conclude with a call to develop a greater awareness of the potential of fiction for learning, and for writers to produce more focused stories engaging with environmental responsibility and activism

Features of dog ecology relevant to rabies spread in Machakos District, Kenya

A random sample of households in Machakos District of Kenya was surveyed using personal interviews to determine features of dog ecology relevant to the spread of rabies. A mean of 1,35 dogs/household, a dog to person ratio of 1:9,6 and a mean of 10,4 dogs/km² were estimated. The male to female ratio was 1:0,67 with 26% of the dog population being less than three months old. The dogs had a mean age of 1,8 years. The proportion of the dogs which fed on household leftovers and waste was 94,7%. Dogs were restricted in 19,4% of the households, while 69% of the dogs spent all of their time free outdoors. One-third of the dog population over three months old had been vaccinated against rabies. Considering the endemic status of rabies in Machakos District, methods which could be devised to control the disease are discussed.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Relativistic corrections in (gamma,N) knockout reactions

We develop a fully relativistic DWIA model for photonuclear reactions using the relativistic mean field theory for the bound state and the Pauli reduction of the scattering state which is calculated from a relativistic optical potential. Results for the 12C(gamma,p) and 16O(gamma,p) differential cross sections and photon asymmetries are displayed in a photon energy range between 60 and 257 MeV, and compared with nonrelativistic DWIA calculations. The effects of the spinor distortion and of the effective momentum approximation for the scattering state are discussed. The sensitivity of the model to different prescriptions for the one-body current operator is investigated. The off-shell ambiguities are large in (gamma,p) calculations, and even larger in (gamma,n) knockout.Comment: LaTeX2e, 18 pages, and 6 figure
