Uncovering Adaptive Versus Acclimatized Alterations In Standard Metabolic Rate In Brown Bullhead (Ameiurus Nebulosus), Tood A. Leadley, Anne Mcleod, Timothy B. Johnson, Daniel D. Heath, Ken G. Drouillard
Uncovering Adaptive Versus Acclimatized Alterations In Standard Metabolic Rate In Brown Bullhead (Ameiurus Nebulosus), Tood A. Leadley, Anne Mcleod, Timothy B. Johnson, Daniel D. Heath, Ken G. Drouillard
Great Lakes Institute for Environmental Research Publications
Standard metabolic rates (SMR) were measured in Brown Bullheads collected from two locations of the Detroit River, North America, representative of highly contaminated and uncontaminated areas. Measurements of SMR were completed within 10 d of fish collections (acute trials), for fish held in a common pond environment for 1 year (clearance trials) and for F1 generation fish raised in the pond environment (F1 study). SMRs were significantly higher (26%) in fish from the contaminated area during acute trials. Both populations showed large decreases in SMR (49 to 52 %) following clearance, however, differences between populations were still evident. There were …
A Review Of Structural Patterns And Melting Processes In The Archean Craton Of West Greenland: Evidence For Crustal Growth At Convergent Plate Margins As Opposed To Non-Uniformitarian Models, Ali Polat
Earth & Environmental Sciences Publications
The Archean craton of West Greenland consists of many fault-bounded Eoarchean to Neoarchean tectonic terranes (crustal blocks). These tectonic terranes are composed mainly of tonalite-trondhjemite-granodiorite (TTG) gneisses, granitic gneisses, metavolcanic-dominated supracrustal belts, layered anorthositic complexes, and late- to post-tectonic granites. Rock assemblages and geochemical signatures in these terranes suggest that they represent fragments of dismembered oceanic island arcs, consisting mainly of TTG plutons, tholeiitic to calc-alkaline basalts, boninites, picrites, and cumulate layers of ultramafic rocks, gabbros, leucogabbros and anorthosites, with minor sedimentary rocks. The structural characteristics of the terrane boundaries are consistent with the assembly of these island arcs through …

Α-Tocopherol Is Well Designed To Protect Polyunsaturated Phospholipids: Md Simulations, Xiaoling Leng, Jacob J. Kinnun, Drew Marquardt, Mikel Ghefli, Norbert Kučerka, John Katsaras, Jeffrey Atkinson, Thad A. Harroun, Scott E. Feller, Stephen R. Wassall
Chemistry and Biochemistry Publications
The presumptive function for alpha-tocopherol (αtoc) in membranes is to protect polyunsaturated lipids against oxidation. Although the chemistry of the process is well established, the role played by molecular structure that we address here with atomistic molecular-dynamics simulations remains controversial. The simulations were run in the constant particle NPT ensemble on hydrated lipid bilayers composed of SDPC (1-stearoyl-2-docosahexaenoylphosphatidylcholine, 18:0-22:6PC) and SOPC (1-stearoyl-2-oleoylphosphatidylcholine, 18:0-18:1PC) in the presence of 20 mol % αtoc at 37°C. SDPC with SA (stearic acid) for the sn-1 chain and DHA (docosahexaenoic acid) for the sn-2 chain is representative of polyunsaturated phospholipids, while SOPC with OA (oleic …
A Self-Assembled, Low-Cost, Microstructured Layer For Extremely Stretchable Gold Films, Tricia Carmichael, Heather L. Filiatrault, R. Stephen Carmichael, Rachel A. Boutette
A Self-Assembled, Low-Cost, Microstructured Layer For Extremely Stretchable Gold Films, Tricia Carmichael, Heather L. Filiatrault, R. Stephen Carmichael, Rachel A. Boutette
Chemistry and Biochemistry Publications
We demonstrate a simple, low-cost, and green approach to deposit a microstructured coating on the silicone elastomer polydimethylsiloxane (PDMS) that can be coated with gold to produce highly stretchable and conductive films. The microstructured coating is fabricated using an aqueous emulsion of poly(vinyl acetate) (PVAc): common, commercially available white glue. The aqueous glue emulsion self-assembles on the PDMS surface to generate clustered PVAc globules, which can be conformally coated with gold. The microstructured surface provides numerous defect sites that localize strain when the structure is stretched, resulting in the initiation of numerous microcracks. As the structure is further elongated, the …

Both mercury (Hg) and polychlorinated biphenyls (PCBs) demonstrate food web biomagnification in aquatic ecosystems, yet their toxicokinetics have not been simultaneously contrasted within a common fish species. This study quantifies uptake and elimination rates of Hg and PCBs in goldfish. Fish were exposed to contaminated food containing PCBs and Hg to determine dietary chemical assimilation efficiencies (AEs) and elimination coefficients (ktot). To test first-order kinetics, three exposure regimes were established by varying the proportion of contaminated fish incorporated into the food. Dietary AEs were 98 ± 10, 75 ± 12, and 40 ± 9% for MeHg, THg, and …
