Temporal Resolution And Spectral Sensitivity Of The Visual System Of Three Coastal Shark Species From Different Light Environments, D. Michelle Mccomb, Tamara M. Frank, Robert E. Hueter, Stephen M. Kajiura

Marine & Environmental Sciences Faculty Articles

Visual temporal resolution and scotopic spectral sensitivity of three coastal shark species (bonnethead Sphyrna tiburo, scalloped hammerhead Sphyrna lewini, and blacknose shark Carcharhinus acronotus) were investigated by electroretinogram. Temporal resolution was quantified under photopic and scotopic conditions using response waveform dynamics and maximum critical flicker‐fusion frequency (CFF). Photopic CFF_max was significantly higher than scotopic CFF_max in all species. The bonnethead had the shortest photoreceptor response latency time (23.5 ms) and the highest CFF_max (31 Hz), suggesting that its eyes are adapted for a bright photic environment. In contrast, the blacknose had the longest response …

Maternal Consumption Of Canola Oil Suppressed Mammary Gland Tumorigenesis In C3(1) Tag Mice Offspring, Gabriela Ion, Juliana A. Akinsete, W. Elaine Hardman

Biochemistry and Microbiology

Background: Maternal consumption of a diet high in omega 6 polyunsaturated fats (n-6 PUFA) has been shown to increase risk whereas a diet high in omega 3 polyunsaturated fats (n-3 PUFA) from fish oil has been shown to decrease risk for mammary gland cancer in female offspring of rats. The aim of this study was to determine whether increasing n-3 PUFA and reducing n-6 PUFA by using canola oil instead of corn oil in the maternal diet might reduce the risk for breast cancer in female offspring.

Methods: Female SV 129 mice were divided into two groups and placed on …

Willingness To Pay Estimation When Protest Beliefs Are Not Separable From The Public Good Definition, Kimberly Rollins, M.D.R. Evans, Mimako Kobayashi, Anita Castledine

Reports

Public good attributes that are correlated with protest beliefs but not separable from the good's value, would affect stated preference estimates of the WTP for the public good. Survey data collected to value a program to prevent ecosystem losses on Nevada rangelands, where the majority of land is publicly owned and managed, reveal more than half of the respondents exhibiting some protest belief. Of these, about 60% voted 'yes' to some nonzero bid amount. By treating protest beliefs and opposition to the proposed program as separate concepts, we systematically analyze their determinants and impacts on WTP. In this framework, people …

Defining The Genus Hydropsyche (Trichoptera:Hydropsychidae) Based On Dna And Morphological Evidence, Christy Jo Geraci, Xin Zhou, John C. Morse, Karl M. Kjer

Publications

In this paper, we review the history of Hydropsychinae genus-level classification and nomenclature and present new molecular evidence from mitochondrial cytochrome c oxidase subunit I (COI) and nuclear large subunit ribosomal ribonucleic acid (28S) markers supporting the monophyly of the genus Hydropsyche. Both molecular and morphological characters support a broad conservative definition of Hydropsyche. Caledopsyche, Hydatomanicus, and Occutanspsyche are synonymized with Hydropsyche. The following species groups are established: Hydropsyche bronta Group (generally corresponding with Ceratopsyche and Hydropsyche morosa and newae Groups), Hydropsyche colonica Group (generally corresponding with Orthopsyche), Hydropsyche instabilis Group (generally corresponding with Hydropsyche s.s.), and Hydropsyche naumanni Group …

Development And Validation Of A Rapid Method For The Detection Of Latrunculol A In Plasma., Jiajiu Shaw, Frederick A. Valeriote, Joseph Media, Tyler A. Johnson, Taro Amagata, Karen Tenney, Phillip Crews

Natural Sciences and Mathematics | Faculty Scholarship

Latrunculol A is a recently discovered 6,7-dihydroxy analog of the potent actin inhibitor latrunculin A. Latrunculol A has exhibited greater cytotoxicity than latrunculin A against both murine and human colon tumor cell lines in vitro. Currently, there are no reports regarding the bioavailability of latrunculol A in vivo. This study was undertaken as a prelude to pharmacokinetic assessments and it is the first work where bioavailability of latrunculol A was studied. In the present work, a simple plasma preparation and a rapid HPLC method have been developed. Mouse plasma containing latrunculol A was first treated by acetonitrile and then centrifuged …

Determination Of The Pharmacokinetics And Oral Bioavailability Of Salicylamine, A Potent Γ-Ketoaldehyde Scavenger, By Lc/Ms/Ms, Irene Zagol-Ikapitte, Elena Matafonova, Venkataraman Amarnath, Christopher L. Bodine, Olivier Boutaud, Rommel G. Tirona, John A. Oates, L. Jackson Roberts, Sean S. Davies

Paediatrics Publications

Levels of reactive γ-ketoaldehydes derived from arachidonate increase in diseases associated with inflammation and oxidative injury. To assess the biological importance of these γ-ketoaldehydes, we previously identified salicylamine as an effective γ-ketoaldehyde scavenger in vitro and in cells. To determine if salicylamine could be administered in vivo, we developed an LC/MS/MS assay to measure salicylamine in plasma and tissues. In mice, half-life (t1/2) was 62 minutes. Drinking water supplementation (1-10 g/L) generated tissue concentrations (10-500 μM) within the range previously shown to inhibit γ-ketoaldehydes in cells. Therefore, oral administration of salicylamine can be used to assess the contribution of γ-ketoaldehydes …

Influence Of Prescribed Fire On Ecosystem Biomass, Carbon, And Nitrogen In A Pinyon Juniper Woodland, Benjamin M. Rau, Robin Tausch, Alicia Reiner, Dale W. Johnson, Jeanne C. Chambers, Robert R. Blank, Annmarrie Lucchesi

Articles

Increases in pinyon and juniper woodland cover associated with land-use history are suggested to provide offsets for carbon emissions in arid regions. However, the largest pools of carbon in arid landscapes are typically found in soils, and aboveground biomass cannot be considered long-term storage in fire-prone ecosystems. Also, the objectives of carbon storage may conflict with management for other ecosystem services and fuels reduction. Before appropriate decisions can be made it is necessary to understand the interactions between woodland expansion, management treatments, and carbon retention. We quantified effects of prescribed fire as a fuels reduction and ecosystem maintenance treatment on …

A Model-Based Approach For Making Ecological Inference From Distance Sampling Data, Devin S. Johnson, Jeffrey L. Laake, Jay M. Ver Hoef

United States Department of Commerce: Staff Publications

We consider a fully model-based approach for the analysis of distance sampling data. Distance sampling has been widely used to estimate abundance (or density) of animals or plants in a spatially explicit study area. There is, however, no readily available method of making statistical inference on the relationships between abundance and environmental covariates. Spatial Poisson process likelihoods can be used to simultaneously estimate detection and intensity parameters by modeling distance sampling data as a thinned spatial point process. A model-based spatial approach to distance sampling data has three main benefits: it allows complex and opportunistic transect designs to be employed, …

Double-Observer Line Transect Methods: Levels Of Independence, Stephen T. Buckland, Jeffrey L. Laake, David L. Borchers

United States Department of Commerce: Staff Publications

Double-observer line transect methods are becoming increasingly widespread, especially for the estimation of marine mammal abundance from aerial and shipboard surveys when detection of animals on the line is uncertain. The resulting data supplement conventional distance sampling data with two-sample mark–recapture data. Like conventional mark–recapture data, these have inherent problems for estimating abundance in the presence of heterogeneity. Unlike conventional mark–recapture methods, line transect methods use knowledge of the distribution of a covariate, which affects detection probability (namely, distance from the transect line) in inference. This knowledge can be used to diagnose unmodeled heterogeneity in the mark–recapture component of the …

What Contributions Are Invasive Plant Species Making To Ecosystem Services?, Stephen L. Young

West Central Research and Extension Center, North Platte

Invasive plant species can establish in diverse environments, and, with the increase in human mobility, they are no longer restricted to isolated pockets in remote parts of the world. Cheatgrass (Bromus tectorum L.) in rangelands, purple loosestrife (Lythrum salicaria L.) in wetlands, and tamarisk (Tamarix spp.) in riparian areas are examples of invasive plant species that are common to the United States and can be found in monocultures and patches covering many thousands of hectares. Across the world, invasive plant species like water hyacinth (Eichhornia crassipes), cogon grass (Imperata cylindrica), and mile-a-minute weed …

Structural Assessment Of The Effects Of Amino Acid Substitutions On Protein Stability And Protein-Protein Interaction, Shaolei Teng, Liangjiang Wang, Anand K. Srivastava, Charles E. Schwartz, Emil Alexov

Publications

A structure-based approach is described for predicting the effects of amino acid substitutions on protein function. Structures were predicted using a homology modelling method. Folding and binding energy differences between wild-type and mutant structures were computed to quantitatively assess the effects of amino acid substitutions on protein stability and protein–protein interaction, respectively. We demonstrated that pathogenic mutations at the interaction interface could affect binding energy and destabilise protein complex, whereas mutations at the non-interface might reduce folding energy and destabilise monomer structure. The results suggest that the structure-based analysis can provide useful information for understanding the molecular mechanisms of diseases.

One-Pot Enzymatic Synthesis Of Deoxy-Thymidine-Diphosphate (Tdp)-2-Deoxy-∝-D-Glucose Using Phosphomannomutase, Yung-Hum Yang, Young Bok (Abraham) Kang, Dae-Hee Kim, Tek-Hyung Lee, Sung-Hee Park, Kwangwon Lee, Dongwon Yoo, Kwang-Kyung Liou, Hee-Chan Lee, Jae-Kyung Sohng, Byung-Gee Kim

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Production of deoxy-thymidine-diphosphate (TDP)-sugars as substrates of glycosyltransferases, has been one of main hurdles for combinatorial antibiotic biosynthesis, which combines sugar moiety with aglycon of various antibiotics. Here, we report the one-pot enzymatic synthesis of TDP-2-deoxy-glucose employing high efficient TMP kinase (TMK; E.C. 2.7.2.12), acetate kinase (ACK; E.C. 2.7.1.21), and TDP-glucose synthase (TGS; E.C. 2.7.7.24) with phosphomannomutase (PMM; E.C. 5.4.2.8). In this study, replacing phosphoglucomutase (PGM; E.C. 5.4.2) by PMM from Escherichia coli gave four times higher specific activity on 2-deoxy-6-phosphate glucose, suggesting that the activity on 2-deoxy-glucose-6-phosphate was mainly affected by PMM activity, not PGM activity. Using an in …

Background: In October 2007, a cluster of patients experiencing a novel polyradiculoneuropathy was identified at a pork abattoir (Plant A). Patients worked in the primary carcass processing area (warm room); the majority processed severed heads (head-table). An investigation was initiated to determine risk factors for illness.

Methods and Results: Symptoms of the reported patients were unlike previously described occupational associated illnesses. A case-control study was conducted at Plant A. A case was defined as evidence of symptoms of peripheral neuropathy and compatible electrodiagnostic testing in a pork abattoir worker. Two control groups were used - randomly selected non-ill warm-room workers …

Arrival Then Denial: Interpreting §203(A) Of The Clean Air Act, Analyzing Evidentiary Challenges, & Assessing Conflicting Statutory Directives, Jesse Levine

Distinguished Student Research Papers

An “arrival then denial” occurs when uncertified engines arrive at a U.S. port, but are denied entry to the U.S. by Customs & Border Protection (Customs). Why does this matter? In most cases these uncertified engines are sent back to the country of origin. However, due to resource constraints, a sizeable number of uncertified engines slip past Customs and enter the U.S. each year. Uncertified engines, without proper controls, have been estimated to emit at least 30% more emissions than their certified counterparts. Such emissions exacerbate climate change, acid rain, and air quality generally. EPA attorneys assert that their best …

The Effects Of Instructor-Avatar Immediacy In Second Life, An Immersive And Interactive 3d Virtual Environment, Sabine Karine Lawless-Reljic Edd

A Survey Of The Management And Development Of Captive African Elephant (Loxodonta Africana) Calves: Birth To Three Months Of Age, Nicole L. Kowalski, Robert H.I. Dale, Christa L. H. Mazur

Scholarship and Professional Work - LAS

We used four surveys to collect information about the birth, physical growth, and behavioral development of 12 African elephant calves born in captivity. The management of the birth process and neonatal care involved a variety of standard procedures. All of the calves were born at night, between 7PM and 7AM. The calves showed a systematic progression in behavioral and physical development, attaining developmental milestones at least a quickly as calves in situ. This study emphasized birth-related events, changes in the ways that calves used their trunks, first instances of behaviors, and interactions of the calves with other, usually adult, elephants. …

Conceptions Regarding Children’S Health: An Examination Of Ethnotheories In A Sending And Receiving Community, Maria Rosario De Guzman, Jennifer Deleon, Gloria Gonzalez-Kruger, Rodrigo Cantarero

Department of Child, Youth, and Family Studies: Faculty Publications

Ethnotheories are beliefs that adults hold about children and the factors that impact upon their development. Scholars suggest that “ethnotheories” serve as cultural models that underlie motivations for parenting practices and the way adults organize children’s early experiences. This study examines Mexican adults’ ethnotheories about children’s health in two communities that are linked by transnational migrants and serve as sending and receiving communities for workers. Forty-four Mexican adults in six focus groups discussed well-being issues affecting children in their communities. Qualitative analyses using grounded theory revealed a complex conception of children’s health issues that included physical, psychological, and behavioral components …

Simultaneous Separation And Detection Of Cations And Anions Ion A Microfluidic Device With Suppressed Electroosmotic Flow And A Single Injection Point, B. R. Reschke, J. Schiffbauer, Boyd F. Edwards, A. T. Timperman

All Physics Faculty Publications

A rapid and simultaneous separation of cationic and anionic peptides and proteins in a glass microfluidic device that has been covalently modified with a neutral poly(ethylene glycol) (PEG) coating to minimize protein adsorption is presented. The features of the device allow samples that contain both anions and cations to be introduced from a central flow stream and separated in different channels with different outlets—all in the presence of low electroosmotic flow (EOF) imparted by the PEG coating. The analytes are electrophoretically extracted from a central hydrodynamic stream and electrophoretically separated in two different channels, in which pressure driven flow has …
