Biochemical And Genetic Conservation Of Fission Yeast Dsk1 And Human Srpk1, Zhaohua Irene Tang, Tiffany Kuo, Jenny Shen, Ren-Jang Lin

WM Keck Science Faculty Papers

Arginine/serine-rich (RS) domain-containing proteins and their phosphorylation by specific protein kinases constitute control circuits to regulate pre-mRNA splicing and coordinate splicing with transcription in mammalian cells. We present here the finding that similar SR networks exist in Schizosaccharomyces pombe. We previously showed that Dsk1 protein, originally described as a mitotic regulator, displays high activity in phosphorylating S. pombe Prp2 protein (spU2AF59), a homologue of human U2AF65. We now demonstrate that Dsk1 also phosphorylates two recently identified fission yeast proteins with RS repeats, Srp1 and Srp2, in vitro. The phosphorylated proteins bear the same phosphoepitope found in mammalian SR proteins. Consistent …

A Mycobacterium Ulcerans Toxin, Mycolactone, Causes Apoptosis In Guinea Pig Ulcers And Tissue Culture Cells, Kathleen M. George, Lisa Pascopella, Diane M. Welty, P. L. C. Small

Public and Community Health Sciences Faculty Publications

Mycobacterium ulcerans is the causative agent of Buruli ulcer, a tropical ulcerative skin disease. One of the most intriguing aspects of this disease is the presence of extensive tissue damage in the absence of an acute inflammatory response. We recently purified and characterized a macrolide toxin, mycolactone, from M. ulcerans. Injection of this molecule into guinea pig skin reproduced cell death and lack of acute inflammatory response similar to that seen following the injection of viable bacteria. We also showed that mycolactone causes a cytopathic effect on mouse fibroblast L929 cells that is characterized by cytoskeletal rearrangements and growth arrest …

Typewriter Words: All Fingers Used, Rex Gooch

Word Ways

In "Typewriter Words" in the November Word Ways, Mike Keith define isofinger words as those in which each finger is used at most once (fo eight-letter words, each finger used exactly once). I find the ter isofinger unfortunate, since iso- means "equal" when the opposite I intended. As possible alternatives, I propose hertofinger (somewhat un gainly), heterodigital (hybrid components), or pandigital (in my opinion the biggest).

Agonistic Behaviour And Biogenic Amines In Shore Crabs Carcinus Maenas, Lynne U. Sneddon, Alan C. Taylor, Felicity A. Huntingford, David G. Watson

Sentience Collection

To investigate the role of certain neurohormones in agonistic behaviour, fights were staged between pairs of size-matched male shore crabs Carcinus maenas, and blood samples were taken immediately after the contests had been resolved. Samples were also taken from these crabs at rest (before and after fighting) and after walking on a treadmill. A control group of crabs also had samples taken on each experimental day. Concentrations of tyramine, dopamine, octopamine, serotonin (5-HT) and norepinephrine were determined in each blood sample using a gas chromatography/mass spectrometry (GC-MS) system. Norepinephrine was not detectable in any of the samples, but the standards …

Adsorption Of Pb And Cd Onto Metal Oxides And Organic Material In Natural Surface Coatings As Determined By Selective Extractions: New Evidence For The Importance Of Mn And Fe Oxides, Deming Dong, Yarrow M. Nelson, Leonard W. Lion, Michael L. Shuler, Whilliam C. Ghiorse

Civil and Environmental Engineering

Surface coatings (biofilms and associated minerals) were collected on glass slides in the toxic surface waters of Cayuga Lake (New York State, U.S.A.) and were used to evaluate the relative contributions of Fe, Mn and Al oxides and organic material to total observed Pb and Cd adsorption by the surface coating materials. Several alternative selective extraction techniques were evaluated with respect to both selectivity and alteration of the residual unextracted material. Pb and Cd adsorption was measured under controlled laboratory conditions (mineral salts solution with defined metal speciation, ionic strength 0.05 M, 25°C and pH 6.0) before and after extractions …

Estimation Of Base Temperatures For Nine Weed Species, Scott J. Steinmaus, Timothy S. Prather, Jodie S. Holt

Biological Sciences

Experiments were conducted to test several methods for estimating low temperature thresholds for seed germination. Temperature responses of nine weeds common in annual agroecosystems were assessed in temperature gradient experiments. Species included summer annuals (Amaranthus albus, A. palmeri, Digitaria sanguinalis, Echinochloa crus-galli, Portulaca oleracea, and Setaria glauca), winter annuals (Hirschfeldia incana and Sonchus oleraceus), and Conyza canadensis, which is classified as a summer or winter annual. The temperature below which development ceases (T_base) was estimated as the x-intercept of four conventional germination rate indices regressed on temperature, by repeated probit analysis, …

Does Market Timing Contribute To The Cattle Cycle?, Stephen F. Hamilton, Terry L. Kastens

Economics

Recent evidence suggests that cyclical cattle inventories are driven by exogenous shocks. This article examines a second possible contributing factor to the cattle cycle: a market timing effect that arises from individual attempts to maintain countercyclical inventories. The model uncovers an important conceptual point: to the extent that cycles are driven by exogenous shocks, a representative producer should outperform one who maintains a constant inventory; whereas, for cycles induced by market timing, a representative producer should underperform one with a constant inventory. Simulated net returns over 1974–98 reveal that a constant-inventory manager significantly outperformed the representative U.S. producer, which indicates …

Selenium Poisoning Of Wildlife And Western Agriculture: Cause And Effect, N. E. Korte

All U.S. Government Documents (Utah Regional Depository)

This project examined the hypothesis that selenium contamination is not the principal cause of the decline of endemic fish species in the Upper Colorado Basin. Activities employed to test this hypothesis included a reconnaissance of locations altered by recent road construction, a reinterpretation of available literature regarding selenium toxicity, and the interpretation of unpublished data obtained from the Upper Colorado Basin Fish Recovery Program. The project demonstrates that most of the evidence implicating selenium is circumstantial. Specifically, this research demonstrates that neither the historical record nor the technical literature consistently supports the emphasis given selenium toxicity. For example, many locations …

Protecting And Sharing Western Australia's Coastal Fish Resources. The Path To Integrated Management., Fisheries Western Australia

Fisheries Management Papers

The fisheries management framework of the 21st Century must not only be able to manage the level of exploitation by commercial and recreational fisheries, but also provide an agreed basis and process for changes in the way fish and aquatic resources are used and shared by this community. There is a clear need to counter inevitable pressure on stocks from the impact of a growing population, increasing coastal development and the demands of various key user groups. Unless we are proactive in dealing with the growing exploitation of fisheries along our State’s vast 12,000km coastline, it will be difficult to …

Management Directions For Western Australia's Recreational Fisheries, Fisheries Western Australia

Fisheries Management Papers

A major challenge for the Western Australian community is to ensure the sustainability of these resources in the face of growing pressure, and to ensure that the industries based on these resources are able to develop in a controlled and sustainable fashion which will optimise long-term benefits to the community. Several recreational fisheries, including marron and Shark Bay inner gulf snapper, have shown definitive signs of over-exploitation due to recreational fishing, and there is little doubt that this trend will continue in many near-shore fisheries as the human population increases, unless a new and innovative approach to management is adopted …

Genetic Variation Among Endosymbionts Of Widely Distributed Vestimentiferan Tubeworms, Carol A. Di Meo, Ami E. Wilbur, William E. Holben, Robert A. Feldman, Robert C. Vrijenhoek, S. Craig Cary

Biological Sciences Faculty Publications

Vestimentiferan tubeworms thriving in sulfidic deep-sea hydrothermal vents and cold seeps are constrained by their nutritional reliance on chemoautotrophic endosymbionts. In a recent phylogenetic study using 16S ribosomal DNA, we found that endosymbionts from vent and seep habitats form two distinct clades,vith little variation within each clade. In the present study, we used two different approaches to assess the genetic variation among biogeographically distinct vestimentiferan symbionts, DNA sequences were obtained for the noncoding, internal transcribed spacer (ITS) regions of the rRNA operons of symbionts associated with six different genera of vestimentiferan tubeworms. ITS sequences from endosymbionts of host genera collected …

Impact Of Bovine Oocyte Maturation Media On Oocyte Transcript Levels, Blastocyst Development, Cell Number, And Apoptosis., A J Watson, P De Sousa, A Caveney, L C Barcroft, D Natale, J Urquhart, M E Westhusin

Obstetrics & Gynaecology Publications

The objectives were 1) to investigate the effects of oocyte maturation in serum-free and amino acid-supplemented defined media on oocyte transcript levels, blastocyst cell number, and apoptosis; 2) to investigate the influence of oocyte maturation culture atmosphere on blastocyst development, total cell number, and apoptosis; and 3) to examine the influence of epidermal growth factor (EGF) during oocyte maturation on blastocyst cell number and apoptosis. The results demonstrate that blastocysts derived from in vitro maturation, fertilization, and embryo culture protocols undergo apoptosis but that apoptotic levels are not greatly influenced by the oocyte maturation environment. Amino acid supplementation of oocyte …
