Positive Interactions Among Foraging Seabirds, Marine Mammals And Fishes And Implications For Their Conservation, Richard R. Veit, Nancy M. Harrison

Publications and Research

There is increasing recognition of the importance of “positive interactions” among species in structuring communities. For seabirds, an important kind of positive interaction is the use of birds of the same species, birds of other species, and other marine predators such as cetaceans, seals and fishes as cues to the presence of prey. The process by which a single bird uses, say, a feeding flock of birds as a cue to the presence of prey is called “local enhancement” or “facilitation.” There are subtly different uses of each of these terms, but the issue we address here is the ubiquity …

Role Of Microglial Amylin Receptors In Mediating Beta Amyloid (Aβ)-Induced Inflammation, Wen Fu, Vlatka Vukojevic, Aarti Patel, Rania Soudy, David Mactavish, David Westaway, Kamaljit Kaur, Valeri Goncharuk, Jack Jhamandas

Pharmacy Faculty Articles and Research

Background: Neuroinflammation in the brain consequent to activation of microglia is viewed as an important component of Alzheimer’s disease (AD) pathology. Amyloid beta (Aβ) protein is known to activate microglia and unleash an inflammatory cascade that eventually results in neuronal dysfunction and death. In this study, we sought to identify the presence of amylin receptors on human fetal and murine microglia and determine whether Aβ activation of the inflammasome complex and subsequent release of cytokines is mediated through these receptors.

Methods: The presence of dimeric components of the amylin receptor (calcitonin receptor and receptor activity modifying protein 3) …

Anthropometric Factors And Cutaneous Melanoma: Prospective Data From The Population-Based Janus Cohort, Jo S. Stenehjem, Marit B. Veierød, Lill Tove Nilsen, Reza Ghiasvand, Bjørn Johnsen, Tom K. Grimsrud, Ronnie Babigumira, Judy R. Rees, Trude E. Robsahm

Dartmouth Scholarship

The aim of the present study was to prospectively examine risk of cutaneous melanoma (CM) according to measured anthropometric factors, adjusted for exposure to ultraviolet radiation (UVR), in a large population-based cohort in Norway. The Janus Cohort, including 292,851 Norwegians recruited 1972–2003, was linked to the Cancer Registry of Norway and followed for CM through 2014. Cox regression was used to estimate hazard ratios (HRs) of CM with 95% confidence intervals (CIs). Restricted cubic splines were incorporated into the Cox models to assess possible non-linear relationships. All analyses were adjusted for attained age, indicators of UVR exposure, education, and smoking …

Unexpected High Intragenomic Variation In Two Of Three Major Pest Thrips Species Does Not Affect Ribosomal Internal Transcribed Spacer 2 (Its2) Utility For Thrips Identification, Vivek Kumar, Aaron M. Dickey, Dakshina R. Seal, Robert G. Shatters, Lance S. Osborne, Cindy L. Mckenzie

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The mitochondrial cytochrome oxidase I gene (mtCO1) and the ribosomal internal transcribed spacer 2 region (ITS2) are among the most widely used molecular markers for insect taxonomic characterization. Three economically important species of thrips, Scirtothrips dorsalis, Thrips palmi, and Frankliniella occidentalis were selected to examine the extent of intragenomic variation within these two marker regions in the family Thripidae, and determine if this variation would affect the utility of markers in thrips molecular diagnostics. For each species, intragenomic (within individual) variation and intergenomic (among individuals) variation was assessed by cloning and sequencing PCR-amplified copies. Intergenomic variation was generally higher than …

Ligand Modulation Of Sidechain Dynamics In A Wild-Type Human Gpcr, Lindsay D. Clark, Igor Dikiy, Karen Chapman, Karin Ej Rodstrom, James Aramini, Michael V. Levine, George Khelashvili, Soren Gf Rasmussen, Kevin H. Gardner, Daniel M. Rosenbaum

Publications and Research

GPCRs regulate all aspects of human physiology, and biophysical studies have deepened our understanding of GPCR conformational regulation by different ligands. Yet there is no experimental evidence for how sidechain dynamics control allosteric transitions between GPCR conformations. To address this deficit, we generated samples of a wild-type GPCR (A2AR) that are deuterated apart from 1H/13C NMR probes at isoleucine d1 methyl groups, which facilitated 1H/13C methyl TROSY NMR measurements with opposing ligands. Our data indicate that low [Na+] is required to allow large agonist-induced structural changes in A2AR, and that patterns of sidechain dynamics substantially differ between agonist (NECA) and …

Complex Interplay Of Kinetic Factors Governs The Synergistic Properties Of Hiv-1 Entry Inhibitors., Koree W. Ahn, Michael J. Root

Department of Biochemistry and Molecular Biology Faculty Papers

The homotrimeric HIV-1 envelope glycoprotein (Env) undergoes receptor-triggered structural changes that mediate viral entry through membrane fusion. This process is inhibited by chemokine receptor antagonists (CoRAs) that block Env-receptor interactions and by fusion inhibitors (FIs) that disrupt Env conformational transitions. Synergy between CoRAs and FIs has been attributed to a CoRA-dependent decrease in the rate of viral membrane fusion that extends the lifetime of the intermediate state targeted by FIs. Here, we demonstrated that the magnitude of CoRA/FI synergy unexpectedly depends on FI-binding affinity and the stoichiometry of chemokine receptor binding to trimeric Env. For C-peptide FIs (clinically represented by …

Microfluidic Biopsy Trapping Device For The Real-Time Monitoring Of The Tumor Microenvironment, Angela Holton

USF Tampa Graduate Theses and Dissertations

The tumor microenvironment is composed of cellular and stromal components such as tumor cells, mesenchymal cells, immune cells, cancer associated fibroblasts and the supporting extracellular matrix. The tumor microenvironment provides crucial support for growth and progression of tumor cells and affects tumor response to therapeutic interventions. To better understand tumor biology and to develop effective cancer therapeutic agents it is important to develop preclinical platforms that can faithfully recapitulate the tumor microenvironment and the complex interaction between the tumor and its surrounding stromal elements. Drug studies performed in vitro with conventional two-dimensional cancer cell line models do not optimally represent …

Slave Rebellion, Fugitive Literature, And The Force Of Law, Jeffrey Hole

First-Year Honors Program Research Seminars

From the Stono Rebellion in 1739 to the revolt aboard the ship Amistad in 1839, from Nat Turner’s uprising in 1831 to the raid on Harpers Ferry in 1859—on land and on sea, in U.S. territory and international spaces—slaves and abolitionist allies resisted the legal doctrines and martial enforcement of the slave system. In this presentation, we will explore how nineteenth-century literature imagined and depicted slave rebellion, particularly in the decade before the Civil War and in the aftermath of the 1850 Fugitive Slave Act. A component of the Great Compromise of 1850, the Fugitive Slave Act strengthened a set …

Les Carabidae Du Quebec Et Du Labrador. Andre Larochelle, Dept. De Biologie Du College Bourget, Rigaud, Quebec. Bull. 1:1-255. 1975. $15.00 Canadian., James Liebherr

The Great Lakes Entomologist

(excerpt)

This work is advertised as a catalog of the Carabidae of Quebec, with annotations concerning distribution and bionomics of the various Quebec species. Mr. Larochelle's long range plan is aimed at a complete study of "the ecology, the biology, and the dynamics of those marvelous insects." This, therefore, appears to be the first part of a set of papers similar to Carl Lindroth's studies of Newfoundland carabids (Lindroth, 1955, 1963).

On July 1, 1975, while collecting 18 Pieris napi oleraceal (Harris) in the famous tamarack bog near Mongo, LaGrange Co., Indiana, I collected a somewhat worn male Erynnis funeralis Scudder & Burgess when it was resting on the ground in an area between the bog and a woods.

A New Prey Record For Cerceris Fumipennis Say (Hymenoptera: Sphecidae: Cercerini), Daniel K. Young

The Great Lakes Entomologist

(excerpt)

The sphecid wasp tribe Cercerini is comprised of the genera Cerceris and Eucerceris, the former being widely distributed and the latter restricted to North America All species of Eucerceris for which prey records have been determined utilize snout beetles or weevils (Curculionidae) to feed the young. In North America, known prey records for Cerceris include members of the beetle families Buprestidae, Tenebrionidae, Chrysome- lidae, Bruchidae, and Curculionidae. Some European members of the genus have been

reported to provision the nests with other hymenopterans (e.g. solitary bees of the families Halictidae and Andrenidae) in addition to beetles.

Anaphes (Hymenoptera: Mymaridae) Reared From The Eggs Of A Shore Fly (Diptera: Ephydridae), R. W. Thier, Richard S. Zack, B. A. Foote

The Great Lakes Entomologist

Members of the family Mymaridae are obligate parasitoids of insect eggs, and some species attack the eggs of aquatic insects. Only one account of egg parasitism by the mymarid genus Anaphes on Diptera has been disclosed in the literature. Bakkendorf (1971) bred Anaphes autumnalis Foerster from an egg of Tipula autumnalis Loew.

A Possible Case Of Spatial Isolation In Brine Flies Of The Genus Ephydra (Diptera: Ephydridae), Richard S. Zack, R. W. Thier, B. A. Foote

The Great Lakes Entomologist

(excerpt)

During the summer of 1975, adults and larvae of Ephydra riparia Fallen and E. cinerea Jones were encountered in the many brine pools occurring on the property of the Morton Salt Company at Rittman, Wayne County, Ohio (Scheiring and Foote, 1973). Larvae of both species have been reported to be salt tolerant (Bayly, 1972). E. ripariu larvae can survive in salinities up to 80°/oo (Sutcliffe, 1960), and the larvae of cinerea have been encountered by Nemenz (1960) in the Great Salt Lake of Utah at a salinity of 300°/oo.

An Alternative To Using Fresh Alfalfa For Culturing Colias Philodice Eurytheme Boisduval (Lepidoptera: Pieridae), L. J. Crain, S. J. Roberts, E. J. Armbrust

The Great Lakes Entomologist

Various artificial materials were implemented at each life stage of the alfalfa caterpillar, Colias philodice eurytheme Boisduval, to provide effective and economical replacements for alfalfa. Alfalfa substitutes were used for oviposition and feeding. We also developed a favorable laboratory mating environment. Also, the development of a method for removing disease organisms from eggs without increasing egg mortality was an essential facet of this work. The performance of individuals on artificial surfaces was compared with similar individuals reared on greenhouse alfalfa.

Lethal Temperatures Of Diapausing Bathyplectes Curculionis (Hymenoptera: Ichneumonidae) A Parasite Of The Alfalfa Weevil (Coleoptera: Curculionidae), Ronald H. Cherry, Edward J. Armbrust, William G. Ruesink

The Great Lakes Entomologist

Seasonally acclimatized diapausing larvae of Bathyplectes curculionis (Thomson) were exposed to extreme hxgh and low temperatu~es to determine lethal temperatures for this stage of the parasite. The possible effects of relative humidity on high temperature mortality, mortality induced by repetitive exposures to sublethal temperatures, and differential survival between sexes, were also measured. The upper lethal temperature for summer larvae was 60°C (LDSo from 2 to 4 h), and the lower lethal temperature for winter larvae was -25°C (LDSo from 0 to % h). Summer larvae showed significantly increased mortality with repetitive exposures to sublethal temperatures (55OC) whereas winter larval mortality …

Feeding Habits Of Wisconsin's Predominant Lotic Plecoptera, Ephemeroptera, And Trichoptera, Theodore J. Shapas, William L. Hilsenhoff

The Great Lakes Entomologist

Feeding habits of nymphs or larvae of 101 species of Plecoptera, Ephemeroptera, and Trichoptera collected from Wisconsin's streams were determined by examining foregut contents. The percent by volume of animal, live vascular plant, filamentous algae, diatom, and detrital material recovered is reported. Plecoptera in the suborder Filipalpia were herbivoredetritivores, and most in the suborder Setipalpia were carnivores. Exceptions were Isoperla bilineata (Say), an omnivore, and Isoperla signata (Banks) and I. slossonae (Banks), both detritivore-herbivores. Except for omnivore Ephemerella cornuta Morgan, Ephemeroptera were detritivore-herbivores. Feeding habits of Trichoptera larvae were diverse. Species of Rhyacophilidae, Polycentropodidae, and Phyrganeidae were all carnivores, while …

Force, Torque, And The Electromyogram: A Student Laboratory Exercise, Frank Corotto

Georgia Journal of Science

This paper describes a muscle physiology laboratory exercise that uses electromyography to emphasize the concepts of force and torque and the role of limb position. Students perform a simple laboratory exercise that enables them to relate the angle of a joint with the concepts of force, torque, and the moment arm. Students observe the combined effects of motor unit recruitment and the variation of action potential frequency on the amount of electrical activity a muscle generates. They note that the amount of force a muscle generates also depends on motor unit recruitment and spike frequency. Here, I provide detailed protocols …
