The Rhizobiaceae family of Gram-negative bacteria often engage in symbiosis with plants of economic importance. Historically, genetic studies to identify the function of individual genes, and characterize the biology of these bacteria have relied on the use of classical transposon mutagenesis. To increase the rate of scientific discovery in the Rhizobiaceae(More)
Prion diseases are disorders of protein conformation that produce neurodegeneration in humans and animals. Studies of transgenic (Tg) mice indicate that a factor designated protein X is involved in the conversion of the normal cellular prion protein (PrPC) into the scrapie isoform (PrPSc); protein X appears to interact with PrPC but not with PrPSc. To(More)
We investigated the pulmonary vascular effects of E4021, a potent inhibitor of cGMP-specific phosphodiesterase, in control late-gestation fetal lambs, and in newborn lambs with persistent pulmonary hypertension (PPHN) after prenatal ligation of the ductus arteriosus. E4021 alone significantly relaxed fifth-generation pulmonary arteries isolated from control(More)
The genome of Salmonella enterica subspecies enterica serovar Enteritidis phage type 8 strain EN1660, isolated from an outbreak in Thunder Bay, Canada, was sequenced to 46-fold coverage using an Illumina MiSeq with 300-bp paired-end sequencing chemistry to produce 28 contigs with an N50 value of 490,721 bp.
The free-living legume symbiont Rhizobium leguminosarum is of significant economic value because of its ability to provide fixed nitrogen to globally important leguminous food crops, such as peas and lentils. Discovery based research into the genetics and physiology of R. leguminosarum provides the foundational knowledge necessary for understanding the(More)
Rheinheimera sp. KL1 was isolated from an algal bloom in Katepwa Lake, Saskatchewan, Canada. The isolate shares genetic and physiological similarities with Rheinheimera tangshanensis. The genome is estimated to be 4,295,060 bp in length with a GC content of 46.37%. Sequence analysis suggests the strain carries a previously uncharacterized prophage.
Here, we report the first draft genome sequence of Salmonella enterica subsp. enterica serovar Livingstone. This S. Livingstone strain CKY-S4 displayed biofilm formation and cellulose production and could persist on lettuce. This genome may help the study of mechanisms by which enteric pathogens colonize food crops.
Bacteriophages may play an important role in regulating population size and diversity of the root nodule symbiont Rhizobium leguminosarum, as well as participating in horizontal gene transfer. Although phages that infect this species have been isolated in the past, our knowledge of their molecular biology, and especially of genome composition, is extremely(More)
Elder Research is a leader in the practice of Data Mining-discovering useful patterns in data and successfully harnessing the information gained. The principals are active researchers in Data Mining, contributing to the literature of this emerging field in books, conferences, and through highly-regarded short courses and training seminars. The Institute of(More)
A system for the display and analysis of computerized axial tomography scans has been developed. Selected regions of scans can be outlined using a joystick, allowing rapid statistical analysis. The difference between two scans can be displayed, and coronal and sagittal sections as well as projected displays, can be produced from a series of transverse(More)
