1998
Purpose: Although specific genes play a role in regional retinal disease, the correlation of regional gene expression in the disease-affected site has not been previously ascertained. Non-human primates are widely used in models of human retinal function and are theorized to have identical (to...

Regulation of cold shock-induced RNA helicase gene expression in the cyanobacterium Anabaena sptrain PCC 7120
Download2000
Owttrim, George W., Chamot, Danuta
Expression of the Anabaena sp. strain PCC 7120 RNA helicase gene crhC is induced by cold shock.crhC transcripts are not detectable at 30°C but accumulate at 20°C, and levels remain elevated for the duration of the cold stress. Light-derived metabolic capability, and not light per se, is required...

Coleman, John R. , Owttrim, George W.
The expression of the cyanobacterial recA gene, isolated from Anabaena variabilis, has been examined at the levels of transcript and protein abundance. Exposure of the cyanobacterium to a variety of DNA-damaging agents, including mitomycin C, methyl methanesulfonate, and UV irradiation, results...

Relationships among Fossil and Living Dipteridaceae: Anatomically Preserved Hausmannia from the Lower Cretaceous of Vancouver Island.
Download2006
Little, S. A., Rothwell, G. W., Stockey, R. A.
Anatomically preserved foliage of a dipteridaceous fern has been identified in both calcareous nodules and fine-grained, carbonate-cemented sandstone from the early Cretaceous (Hauterivian-Barremian) Apple Bay locality from Vancouver Island, British Columbia, Canada. Fronds with attached...

Derocher, Andrew E., Skaare, Janneche U., Jenssen, Bjørn Munro, Sørmo, Eugen G., Lie, Elisabeth, Braathen, Marte, Wiig, Øystein
We studied the relationships between polychlorinated biphenyls (PCBs) and thyroid hormones (THs) and retinol within two groups of female polar bears (Ursus maritimus), females with cubs of the year (FWCOY) and females without cubs of the year (FWOCOY), and within a group of males. Concentrations...

Remarkable new birdlike dinosaur (Theropoda: Maniraptora) from the Upper Cretaceous of Montana
Download2000
Burnham, D. A., Bakker, R. T., Currie, P. J., Ostrom, J. H., Kraig, L. D., Zhou, Z.
We describe a small dromaeosaurid dinosaur. Bambiraptor feinbergi n. gen. and n. sp., based upon a nearly complete fossil skeleton from the Two Medicine Formation (Upper Cretaceous) of Montana. Widely known as Bambi, this skeleton is a well-preserved subadult that is about 75 percent adult size....

Reproductive Biology and Evidence for Water Dispersal of Teliospores in Chrysomyxa weirii, a Microcyclic Spruce Needle Rust
Download2000
Hiratsuka, Yasuyuki, Crane, Patricia E., Currah, Randolph S.
Chrysomyxa weirii (Uredinales) is the only autoecious, microcyclic species of Chrysomyxa occurring in North America. The telia form on second-year needles of spruce, causing premature needle loss. The morphology of the telia was studied in herbarium specimens from diverse locations, and the...

Reproductive biology of the Cerro Cuadrado (Jurassic) fossil conifers: Pararaucaria patagonica Wieland
Download1977
Seventy-two silicified cone specimens of Pararaucaria patagonica Wieland from the Cerro Cuadrado (Jurassic) petrified forest in Patagonia were studied by use of thin sections and reflected light. Traces from the cone axis stele to the bract and ovuliferous scale are separate at their origins. In...
