El Nino Southern Oscillation-Related Salinity Variations Recorded In The Skeletal Geochemistry Of A Porites Coral From Espiritu Santo, Vanuatu, K. H. Kilbourne, Terrence M. Quinn, Frederick W. Taylor, Thierry Delcroix, Yves Gouriou Oct 2004

El Nino Southern Oscillation-Related Salinity Variations Recorded In The Skeletal Geochemistry Of A Porites Coral From Espiritu Santo, Vanuatu, K. H. Kilbourne, Terrence M. Quinn, Frederick W. Taylor, Thierry Delcroix, Yves Gouriou

Marine Science Faculty Publications

Coral skeletal geochemistry offers the potential to reconstruct the sea surface salinity (SSS) history of the tropical oceans on seasonal to interannual and perhaps centennial timescales because of the strong link between variation in SSS and seawater δ18O in tropical regions. We explore this potential using a monthly resolved, 65‐year record of skeletal δ18O and Sr/Ca variations in a Porites coral from Espiritu Santo, Vanuatu. We demonstrate that El Niño–Southern Oscillation–related climate variability strongly influences coral δ18O at Santo through local salinity changes associated with the position of the South Pacific Convergence Zone and …

Thermal And Sodium Dodecylsulfate Induced Transitions Of Streptavidin, Mark J. Waner, Irina Navrotskaya, Amanda Bain, Edward D. Oldham, David P. Mascotti Oct 2004

Thermal And Sodium Dodecylsulfate Induced Transitions Of Streptavidin, Mark J. Waner, Irina Navrotskaya, Amanda Bain, Edward D. Oldham, David P. Mascotti

Chemistry

The strong specific binding of streptavidin (SA) to biotin is utilized in numerous biotechnological applications. The SA tetramer is also known to exhibit significant stability, even in the presence of sodium dodecylsulfate (SDS). Despite its importance, relatively little is known about the nature of the thermal denaturation pathway for SA. This work uses a homogeneous SA preparation to expand on the data of previous literature reports, leading to the proposal of a model for temperature induced structural changes in SA. Temperature dependent data were obtained by SDS and native polyacrylamide gel electrophoresis (PAGE), differential scanning calorimetry (DSC), and fluorescence and …


A Subset Of Liver Nk T Cells Is Activated During Leishmania Donovani Infection By Cd1d-Bound Lipophosphoglycan, Joseph L. Amprey, Jin S. Im, Salvatore J. Turco, Henry W. Murray, Petr A. Illarionov, Gurdyal S. Besra, Steven A. Porcelli, Gerald F. Späth Oct 2004

A Subset Of Liver Nk T Cells Is Activated During Leishmania Donovani Infection By Cd1d-Bound Lipophosphoglycan, Joseph L. Amprey, Jin S. Im, Salvatore J. Turco, Henry W. Murray, Petr A. Illarionov, Gurdyal S. Besra, Steven A. Porcelli, Gerald F. Späth

Molecular and Cellular Biochemistry Faculty Publications

Natural killer (NK) T cells are activated by synthetic or self-glycolipids and implicated in innate host resistance to a range of viral, bacterial, and protozoan pathogens. Despite the immunogenicity of microbial lipoglycans and their promiscuous binding to CD1d, no pathogen-derived glycolipid antigen presented by this pathway has been identified to date. In the current work, we show increased susceptibility of NK T cell–deficient CD1d−/− mice to Leishmania donovani infection and Leishmania-induced CD1d-dependent activation of NK T cells in wild-type animals. The elicited response was Th1 polarized, occurred as early as 2 h after infection, and was independent from …

A Comparison Of Behavioural Change In Drosophila During Exposure To Thermal Stress, Angel G. Fasolo, Robert A. Krebs Oct 2004

A Comparison Of Behavioural Change In Drosophila During Exposure To Thermal Stress, Angel G. Fasolo, Robert A. Krebs

Biological, Geological, and Environmental Faculty Publications

In order to understand how adaptive tolerance to stress has evolved, we compared related species and populations of Drosophila for a variety of fitness relevant traits while flies directly experienced the stress. Two main questions were addressed. First, how much variation exists in the frequency of both courtship and mating among D. melanogaster, D. simulans, and D. mojavensis when each are exposed to a range of temperatures? Second, how does variation in these same behaviours compare among four geographically isolated populations of D. mojavensis, a desert species with a well defined ecology? Our hierarchical study demonstrated that mating success under …

Subterranean Loss And Gain Of Water In Mountain Lake, Virginia: A Hydrologic Model, Martin Jansons, Bruce C. Parker, Jacob E. Waller Oct 2004

Subterranean Loss And Gain Of Water In Mountain Lake, Virginia: A Hydrologic Model, Martin Jansons, Bruce C. Parker, Jacob E. Waller

Virginia Journal of Science

Mountain Lake, Virginia is a small, unique, oligotrophic, subalpine ecosystem in the southern Appalachians. Previous studies have disclosed that this lake has manifested periodic prolonged low water levels during the several thousand years of its existence. The most recent low water level occurred during the drought years of 1999-2002. Measurements of lake level, precipitation, and other meteorological data including calculated evapotranspiration in the lake basin from 2/19/02 to 8/31/03 have enabled estimation of net subterranean water losses presumably through cracks between Clinch sandstone boulders and/or the recently discovered deep hole at the northwest end of Mountain Lake. These net losses …

Faculty Research & Creative Activity

Silene regia Sims is an endangered prairie forb in Illinois where small isolated colonies are scattered. In La·wrence County, two sites (Allison Prairie and Chauncey Marsh) have fewer plants (6-23) than two other sites (Cmmty Road and Cemetery) with 26-45 plants. Information on seed germination in these isolated colonies is needed. Our goal was to evaluate seed germination of S. regia from colonies in Lawrence County, illinois. S. regia fruits were collected from these four sites on August 9 and 19, 1999. Seeds were scarified by cutting the seed coat, or they were stratified at 2 C for 12 or …


The Role Of Optimal Healing Environments In The Management Of Childhood Obesity, Marjorie Freedman, Judith Stern Oct 2004

The Role Of Optimal Healing Environments In The Management Of Childhood Obesity, Marjorie Freedman, Judith Stern

Faculty Publications

The prevalence of childhood and adolescent obesity has increased steadily over the past three decades such that obesity is now a major worldwide pediatric health risk factor. Pediatric obesity is associated with significant health problems, and is an important early risk factor for adult morbidity and mortality. This paper focuses on the role and components of optimal healing environments (OHEs) that may be useful in the management of childhood obesity: healing intention, healing relationships, health promotion and disease prevention, and healing spaces. Diet, physical activity, and behavior modification strategies used in the treatment of childhood obesity are also reviewed.


Evidence That Thyroid Hormone Induces Olfactory Cellular Proliferation In Salmon During A Sensitive Period For Imprinting, Sean C. Lema, Gabrielle A. Nevitt Oct 2004

Evidence That Thyroid Hormone Induces Olfactory Cellular Proliferation In Salmon During A Sensitive Period For Imprinting, Sean C. Lema, Gabrielle A. Nevitt

Biological Sciences

Salmon have long been known to imprint and home to natal stream odors, yet the mechanisms driving olfactory imprinting remain obscure. The timing of imprinting is associated with elevations in plasma thyroid hormone levels, with possible effects on growth and proliferation of the peripheral olfactory system. Here, we begin to test this idea by determining whether experimentally elevated plasma levels of 3,5,3′-triiodothyronine (T3) influence cell proliferation as detected by the 5-bromo-2′-deoxyuridine (BrdU) cell birth-dating technique in the olfactory epithelium of juvenile coho salmon (Oncorhynchus kisutch). We also explore how natural fluctuations in thyroxine (T4) …

Kno.e.sis Publications

Due to the complexity of biological systems, interpretation of data obtained by a single experimental approach can often be interpreted only if viewed from a broader context, taking into account the information obtained by many diverse techniques. The vast amount of interpreted experimental data that is now available via the internet opens the possibility of collecting the relevant pieces of information that will enable scientists to form hypotheses based on the integration of this diverse information. However, the sheer volume of data that is available makes it very difficult to select the information necessary to make a coherent model of …

Renesting Decisions And Annual Fecundity Of Female Dickcissels (Spiza Americana) In Illinois, Jeffrey W. Walk, Kevin Wentworth, Eric L. Kershner, Eric K. Bollinger, Richard E. Warner

Faculty Research & Creative Activity

ABSTRACT.-Renesting decisions and annual fecundity are crucial for interpreting other demographic information, yet are infrequently reported. We used radiotelemetry to monitor female Dickcissels (Spiza americana) throughout the 1999 and 2000 breeding seasons in southeastern Illinois. Overall fecundity (regardless of whether females remained in the study area throughout the breeding season) was 0.61 ± 0.13 female fledglings per year. Of females that remained within the study area, 94% fledged young (1.25 ± 0.15 female fledglings per year). Most females (62%) that experienced nest failure emigrated from the study area (moved >10 km) in 2.8 ± 0.6 days; others (36%) initiated subsequent …

Evolution Of Nociception In Vertebrates: Comparative Analysis Of Lower Vertebrates, Lynne U. Sneddon Oct 2004

Evolution Of Nociception In Vertebrates: Comparative Analysis Of Lower Vertebrates, Lynne U. Sneddon

Veterinary Science and Medicine Collection

Nociception is an important sensory system of major fundamental and clinical relevance. The nociceptive system of higher vertebrates is well studied with a wealth of information about nociceptor properties, involvement of the central nervous system and the in vivo responses to a noxious experience are already characterised. However, relatively little is known about nociception in lower vertebrates and this review brings together a variety of studies to understand how this information can inform the evolution of nociception in vertebrates. It has been demonstrated that teleost fish possess nociceptors innervated by the trigeminal nerve and that these are physiologically similar to …

Facultative Altitudinal Movements By Mountain White-Crowned Sparrows (Zonotrichia Leucophrys Oriantha) In The Sierra Nevada, Thomas P. Hahn, Keith W. Sockman, Creagh W. Breuner, Martin L. Morton Oct 2004

Facultative Altitudinal Movements By Mountain White-Crowned Sparrows (Zonotrichia Leucophrys Oriantha) In The Sierra Nevada, Thomas P. Hahn, Keith W. Sockman, Creagh W. Breuner, Martin L. Morton

Biological Sciences Faculty Publications

Mountain White-crowned Sparrows (Zonotrichia leucophrys oriantha) winter in Mexico and often arrive in the vicinity of their breeding grounds in the Sierra Nevada well before nesting is possible. Arrival at Tioga Pass, Califomia (elevation 3,030 m), usually occurs in early May, but residual winter snow and adverse weather can delay nesting for weeks. We used radiotelemetry to determine whether prebreeding Mountain White-crowned Sparrows engaged in weather-related altitudinal movements during the waiting period between the end of spring migration and onset of breeding during 1995-2001, with a range of residual winter snowpacks. Interannual variation in arrival date and onset …

Thin wall microcapsules were formed via Layer-by-Layer Self-Assembly of alternate adsorption of oppositely charged polyelectrolyte on microcores. After the core dissolution, empty polymeric shells with 20–25 nm thick walls were obtained. These microcapsules were loaded with Myoglobin, Hemoglobin and Glucose Oxidase by opening capsule pores at low pH and closing them at higher pH. The native structure of the enzyme was not affected due to different treatments. Biocompatible nanoshells were also prepared for encasing DNA. Using the same Layer-by-Layer Self-Assembly approach nanoparticle were constructed containing DNA as one of the layers. The nanoparticles of different architecture were used to deliver …


Fisheries Research Contract Report No. 8 - The Nutritional Management Of Barramundi, Brett Glencross Oct 2004

Fisheries Research Contract Report No. 8 - The Nutritional Management Of Barramundi, Brett Glencross

Fisheries Research Contract Reports

Barramundi nutrition research has been undertaken since 1988. Since that time the requirements for most nutrients, energy demand, ingredient utilisation and the effects of nutrition on flesh quality aspects have all been examined to varying extents.

Optimal protein content of diets has been shown to vary with diet energy density and also the size of fish which are being fed. Most studies have suggested a protein requirement from 45% to 55%. For small fish a protein to energy ratio of 25 to 30 g/MJ is suggested. Limited work has been done on fish larger than 500 g. The 10 essential …
