Lung tissue from 221 definite and probable cases of malignant mesothelioma reported to the Australian Mesothelioma Surveillance Program from January 1980 through December 1985 and from an age-sex frequency matched control series of 359 postmortem cases were examined by light microscopic (LM) and analytical transmission electron microscopic (TEM) analysis and energy dispersive x-ray analysis (ED...

Twenty-four star-nosed moles, Condylura cristata, collected from the northeastern United States (Maine, Massachusetts, Ohio, Vermont) were examined for coccidian oocysts. All of the moles were infected with from 1 to 4 species of coccidia representing 2 eimerian and 3 isosporan spp., but oocysts of only 4 of these species were present in sufficient numbers for detailed study; these are describe...

Protein Kinase CK1a Regulates mRNA Binding by hnRNP-C in Response to Physiologic Levels of Hydrogen Peroxide* Taj Kattapuram, Suping Yang, Jenny L. Maki † , and James R. Stone From the Department of Pathology, Massachusetts General Hospital, Harvard Medical School, Boston, Massachusetts 02114 Running Title: Protein Kinase CK1a Regulation of hnRNP-C Address correspondence to: James R. Stone, M.D...

We recently demonstrated that the interlobular artery (ILA) constricts in response to elevating renal arterial pressure (RAP), suggesting that the ILA contributes to renal autoregulation. In the present study, we examined the segmental myogenic responsiveness of the ILA in kidneys from Wistar-Kyoto (WKY) rats and spontaneously hypertensive rats (SHR). The tapered nature of the ILA allowed us to...

Natural communities of marine bacteria, an isolate (FMB-Bf3) from one marine community, and Escherichia coli were examined by video microscopy for the magnitude and uniformity of their speed. Natural communities formed tight microswarms that showed higher speeds (mean = 230 microns s-1) than did E. coli (15 microns s-1) or FMB-Bf3 (mean = 62 microns s-1). Outside the microswarms, the marine bac...

Virally induced structures called viral factories form throughout the cytoplasm of cells infected with mammalian orthoreoviruses (MRV). When expressed alone in cells, MRV nonstructural protein microNS forms factory-like structures very similar in appearance to viral factories, suggesting that it is involved in forming the structural matrix of these structures. microNS also associates with MRV c...

The number of cells and their sizes in the corpus allatum (CA) of adult female Blattella germanica, Supella longipalpa and Diploptera punctata were determined during oocyte maturation. Cell number and size were directly measured in cell suspensions following enzymatic dissociation of freshly excised CA. Cell numbers were verified by total cell counts in whole-mount CA monolayers and by hemocyto...

From October 1986 to January 1987, feces from 119 Caiman yacare and 12 Caiman latirostris were collected in Paraguay and later examined for coccidian oocysts; 69 of 119 (58%) samples from C. yacare and 3 of 12 (25%) samples from C. latirostris contained coccidian oocysts. Two eimerians infected C. yacare and both are described as new species. Sporulated oocysts of Eimeria paraguayensis n. sp. a...
