Puvalluttuq: An Epidemic of Tuberculosis at Eskimo Point,Northwest Territories

An explosive epidemic of tuberculosis in a small isolated settlement is described. This outbreak, in a population of 329 Eskimos and 16 whites, produced 80 cases of active tuberculosis, involving 55% of all the house-holds. Forty-five of these patients were children under 10 years of age and only five were persons over 30. These patients probably were infected by one highly infectious individual.The contributing causes of poor housing, overcrowding and poor nutrition, coupled with the debilitating effect of recent epidemics of virus diseases, measles, mumps and German measles, are discussed.Since this article was written, a third resurvey in the same year, conducted in November 1963, revealed 11 more cases among the 279 members of the population who underwent radiological examination; all are hospitalized.     

Adapter-Directed Display: A Modular Design for Shuttling Display on Phage Surfaces

A novel adapter-directed phage display system was developed with modular features. In this system, the target protein is expressed as a fusion protein consisting of adapter GR1 from the phagemid vector, while the recombinant phage coat protein is expressed as a fusion protein consisting of adapter GR2 in the helper phage vector. Surface display of the target protein is accomplished through specific heterodimerization of GR1 and GR2 adapters, followed by incorporation of the heterodimers into phage particles. A series of engineered helper phages were constructed to facilitate both display valency and formats, based on various phage coat proteins. As the target protein is independent of a specific phage coat protein, this modular system allows the target protein to be displayed on any given phage coat protein and allows various display formats from the same vector without the need for reengineering. Here, we demonstrate the shuttling display of a single-chain Fv antibody on phage surfaces between multivalent and monovalent formats, as well as the shuttling display of an antigen-binding fragment molecule on phage coat proteins pIII, pVII, and pVIII using the same phagemid vectors combined with different helper phage vectors. This adapter-directed display concept has been applied to eukaryotic yeast surface display and to a novel cross-species display that can shuttle between prokaryotic phage and eukaryotic yeast systems.

mRNA Differential Display in a Microbial Enrichment Culture: Simultaneous Identification of Three Cyclohexanone Monooxygenases from Three Species

mRNA differential display has been used to identify cyclohexanone oxidation genes in a mixed microbial community derived from a wastewater bioreactor. Thirteen DNA fragments randomly amplified from the total RNA of an enrichment subculture exposed to cyclohexanone corresponded to genes predicted to be involved in the degradation of cyclohexanone. Nine of these DNA fragments are part of genes encoding three distinct Baeyer-Villiger cyclohexanone monooxygenases from three different bacterial species present in the enrichment culture. In Arthrobacter sp. strain BP2 and Rhodococcus sp. strain Phi2, the monooxygenase is part of a gene cluster that includes all the genes required for the degradation of cyclohexanone, while in Rhodococcus sp. strain Phi1 the genes surrounding the monooxygenase are not predicted to be involved in this degradation pathway but rather seem to belong to a biosynthetic pathway. Furthermore, in the case of Arthrobacter strain BP2, three other genes flanking the monooxygenase were identified by differential display, demonstrating that the repeated sampling of bacterial operons shown earlier for a pure culture (D. M. Walters, R. Russ, H. Knackmuss, and P. E. Rouvière, Gene 273:305-315, 2001) is also possible for microbial communities. The activity of the three cyclohexanone monooxygenases was confirmed and characterized following their expression in Escherichia coli.     

Pneumonia in Indian and Eskimo Infants and Children: Part I. A Clinical Study

Ninety-seven Indian and Eskimo infants and children who suffered 112 episodes of pneumonia were the subjects of a prospective study carried out at the Charles Camsell Hospital, Edmonton, Alberta, from August 1963 until August 1964. Investigation included viral studies and an evaluation 10 days after admission. The patients were divided into four diagnostic categories and a comparison was made between cases of bacterial and viral origin. The frequency of right-sided disease, particularly of the upper lobe and/or dependent segment involvement, is described. An evaluation of physical signs is attempted. The problem of recurrent pneumonia and the differential diagnosis of tuberculosis in Indian and Eskimo children with pneumonia is discussed.

The Future is Now: Frontiers on Display at Yale-NAVBO Cardiovascular Inflammation and Remodeling Symposium 2014

Earlier this year, 200 researchers from across the globe gathered at the Omni New Haven Hotel at Yale University in New Haven, Connecticut, for 3 days of talks from 30 of the leading pioneers in modern cardiovascular medicine. From May 8 to 10, 2014, scientists discussed and dissected topics ranging from the clinical treatment of atherosclerosis to the molecular biology of leukocyte-endothelial cell interactions. With other sessions exploring vascular malformation and aneurysm, hypertension, the endothelial-mesenchymal transition (endo-MT), and the role of metabolism in cardiovascular disease, conference participants gained striking insights into rapid advances and ongoing challenges in the field of cardiovascular inflammation and remodeling.
