Effects Of Maternal Growth On Fecundity And Egg Quality Of Wild And Captive Atka Mackerel, Susanne F. Mcdermott, Daniel W. Cooper, Jared L. Guthridge, Ingrid B. Spies, Mike F. Canino, Pamela Woods, Nicola Hillgruber

United States Department of Commerce: Staff Publications

Trade-offs in energy allocation between growth and reproduction can result in variations in reproductive potential in fish with differing growth patterns. Spawning biomass is often used as a proxy for reproductive potential on the assumption that fecundity is directly proportional to body weight. We examined variations in the reproductive potential of Atka mackerel Pleurogrammus monopterygius by studying the effect of differential growth and condition patterns on fecundity, atresia, and egg energy. Fecundity and egg energy were determined for fish from two geographic areas, Seguam Pass and Amchitka Island, Alaska, and compared with those of fish held in captivity. These Atka …

Winter And Summer Upwelling Modes And Their Biological Importance In The California Current Ecosystem, Bryan A. Black, Isaac D. Schroeder, William J. Sydeman, Steven J. Bograd, Brian K. Wells, Franklin B. Schwing

United States Department of Commerce: Staff Publications

Analysis of monthly coastal upwelling intensities revealed two seasonal and biologically relevant upwelling ‘modes’ in the California Current Ecosystem (CCE). The first mode reflected upwelling during the summer months and was characterized by low-frequency (multidecadal) processes, including significant (Po0.01) linear trends at some latitudes. In contrast, the second mode reflected wintertime upwelling and was defined by higher-frequency variability associated with the North Pacific High and El Niño Southern Oscillation events. These modes were compared with multidecadal time series of splitnose rockfish (Sebastes diploproa) otolith growth, yelloweye rockfish (S. ruberrimus) otolith growth, Chinook salmon (Oncorhynchus tshawytscha …

Quality Assessment Of Filtered Smoked Yellowfin Tuna (Thunnus Albacares) Steaks, Lori F. Pivarnik, Cameron Faustman, Santiago Rossi, Surendranath P. Suman, Catherine Palmer, Nicole L. Richard, P. Christopher Ellis, Michael Diliberti

United States Department of Commerce: Staff Publications

Filtered smoke (FS) has been used to preserve taste, texture, and/or color in tuna and other fish species. This treatment is particularly important in color preservation during frozen storage. The objective of this study was to compare changes in the quality profiles of FS-treated and untreated (UT) yellowfin tuna (Thunnus albacares) steaks stored in 3 ways: room temperature (21 to 22 °C), refrigerated (4 to 5 °C), and iced (0 °C). FS and UT steaks were processed from the same lot of fish and analyzed for chemical, microbiological, lipid oxidation, color, and sensory profiles. Similar trends were seen …

Wolves, Canis Lupus, Carry And Cache The Collars Of Radio-Collared White-Tailed Deer, Odocoileus Virginianus, They Killed, Michael E. Nelson, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Wolves (Canis lupus) in northeastern Minnesota cached six radio-collars (four in winter, two in spring-summer) of 202 radio-collared White-tailed Deer (Odocoileus virginianus) they killed or consumed from 1975 to 2010. A Wolf bedded on top of one collar cached in snow. We found one collar each at a Wolf den and Wolf rendezvous site, 2.5 km and 0.5 km respectively, from each deer’s previous locations.

Status And Harvests Of Sandhill Cranes: Mid-Continent, Rocky Mountain, Lower Colorado River Valley And Eastern Populations, Kammie L. Kruse, James A. Dubovsky, Thomas R. Cooper

United States Fish and Wildlife Service: Publications

Compared to increases recorded in the 1970s, annual indices to abundance of the Mid-Continent Population (MCP) of sandhill cranes have been relatively stable since the early 1980s. The spring 2011 index for sandhill cranes in the Central Platte River Valley, Nebraska, uncorrected for visibility bias, was 363,356 birds. The photo-corrected, 3-year average for 2008-10 was 600,892, which is above the established population-objective range of 349,000-472,000 cranes. All Central Flyway States, except Nebraska, allowed crane hunting in portions of their States during 2010-11. An estimated 8,738 hunters participated in these seasons, which was 10% higher than the number that participated in …

Linkages Between Anxiety And Outcomes In Heart Failure, Marla J. De Jong, Misook L. Chung, Jia-Rong Wu, Barbara Riegel, Mary Kay Rayens, Debra K. Moser

Uniformed Services University of the Health Sciences

Objective: We investigated the relationship between anxiety and event-free survival (ie, composite endpoint of death, emergency department visits, or hospitalizations) for patients with heart failure (HF), and examined whether behavioral and physiologic mechanisms mediate any association between anxiety and outcomes.

Methods: In this longitudinal study, patients with HF completed the anxiety subscale of the Brief Symptom Inventory, and heart-rate variability and plasma norepinephrine levels were measured. Dietary adherence and medication adherence were measured according to 24-hour urine sodium level and the Medication Event Monitoring System, respectively. Patients were followed at least 1 year for event-free survival.

Results: In total, 147 …

Bedside Estimation Of Patient Height For Calculating Ideal Body Weight In The Emergency Department, Christine R. Stehman, Robert G. Buckley, Frank L. Dos Santos, Robert H. Riffenburgh, Aaron Senson, Sheila Mulligan, Nathan Mjos, Matt Brewer

Uniformed Services University of the Health Sciences

Background: Ideal body weight (IBW), which can be calculated using the variables of true height and sex, is important for drug dosing and ventilator settings. True height often cannot be measured in the emergency department (ED).

Objectives: Determine the most accurate method to estimate IBW using true height-based IBW that uses true height estimated by providers or patients compared to true height estimated by a regression formula using measured tibial length, and compare all to the conventional 70 kg male/60 kg female standard IBW.

Methods: Prospective, observational, double-blind, convenience sampling of stable adult patients in a tertiary care ED from …

Nicotine Induced Cpg Methylation Of Pax6 Binding Motif In Star Promoter Reduces The Gene Expression And Cortisol Production, Tingting Wang, Man Chen, Lian Liu, Huaiyan Cheng, You-E Yan, Ying-Hong Feng, Hui Wang

Uniformed Services University of the Health Sciences

Steroidogenic acute regulatory protein (StAR) mediates the rate-limiting step in the synthesis of steroid hormones, essential to fetal development. We have reported that the StAR expression in fetal adrenal is inhibited in a rat model of nicotine-induced intrauterine growth retardation (IUGR). Here using primary human fetal adrenal cortex (pHFAC) cells and a human fetal adrenal cell line NCI-H295A, we show that nicotine inhibits StAR expression and cortisol production in a dose- and time-dependent manner, and prolongs the inhibitory effect on cells proliferating over 5 passages after termination of nicotine treatment. Methylation detection within the StAR promoter region uncovers a single …

Investigations Of Transcript Expression In Fathead Minnow (Pimephales Promelas) Brain Tissue Reveal Toxicological Impacts Of Rdx Exposure, Kurt A. Gust, Mitchell S. Wilbanks, Xin Guan, Mehdi Pirooznia, Tanwir Habib, Leslie Yoo, Henri Wintz, Chris D. Vulpe, Edward J. Perkins

United States Army: Publications

Production, usage and disposal of the munitions constituent (MC) cyclotrimethylenetrinitramine (RDX) has led to environmental releases on  military facilities. The chemical attributes of RDX are conducive for leaching to surface water which may put aquatic organisms at risk of exposure. Because RDX has been observed to cause aberrant neuromuscular effects across a wide range of animal phyla, we assessed the effects of RDX on central nervous system (CNS) functions in the representative aquatic ecotoxicological model species, fathead minnow (Pimephales promelas). We developed a fathead minnow brain-tissue cDNA library enriched for transcripts differentially expressed in response to RDX and …

Lysine Requirement For Barrows Fed Ractopamine, Justin W. Bundy, Philip S. Miller, Roman Moreno, Thomas E. Burkey, Erin Hinkle, Huyen Tran

Nebraska Swine Reports

A total of 36 individually penned barrows (initial weight = 176 lb) were used in an experiment conducted to determine the lysine requirement for barrows fed ractopamine during the last 85 lb of the fi nishing phase. There were six dietary treatments that were corn-soybean meal-based with additional crystalline amino acid supplementation. Pigs were assigned to one of six dietary treatments for the duration of the experiment. Treatments included lysine concentrations ranging from 0.5 to 1.3% total lysine. Dietary treatment significantly affected average daily gain and feed efficiency. The total lysine requirement was estimated to be 0.76%. These results indicate …

Production Through Four Parities Of Prolific Females Developed With And Without Energy Restriction, Rodger Johnson, Philip S. Miller, Roman Moreno, Matthew Anderson, Jeffrey Perkins, Donald Mcclure, Thomas Mcgargill, Arlan A. Kettelhake, James E. Spath

Nebraska Swine Reports

This experiment evaluated the effects of developing gilts with ad libitum access to feed to breeding age (226 days) or feed intake restriction from 123 to 226 days of age. Gilts were managed in groups of 10 per pen. Those in the restricted group were fed two meals per day so that energy intake was 75% of that of the ad libitum group. Protein, vitamins , and minerals in their diet were increased so that daily intake of these nutrients was not restricted. A total of 661 gilts of two genetic lines that differed in reproductive rate and in lean …

The Effect Of Corn Distillers Dried Grains With Solubles (Ddgs) On Carcass Quality, Color Stability, And Sensory Characteristics Of Pork, Roman Moreno, Phillip Miller, Thomas E. Burkey, Steven J. Jones, Susan Cuppett, Timothy Carr, Tommi Jones, Ruth Diedrichsen

Nebraska Swine Reports

A study was conducted to evaluate the effect of feeding 0, 5, 10, or 15% distillers dried grains with solubles (DDGS) on carcass quality, color stability, and sensory characteristics of the longissimus muscle (LM) of finishing pigs. Two hundred forty pigs (61.7 lb) were assigned to 1 of 4 dietary treatments with varying concentrations of DDGS (0, 5, 10, and 15%). Live weight, hot carcass weight, and dressing percentage did not change in response to increased dietary DDGS (P = 0.491, 0.807, 0.316, respectively). After 7 days of retail display, yellowness changed due to DDGS inclusion (P = 0.016). No …

Effects Of Distillers Grains With Solubles (Ddgs) And Paylean® Supplementation On Carcass Quality, Color Stability, And Sensory Characteristics Of Pork, Roman Moreno, Philip S. Miller, Thomas E. Burkey, Steven J. Jones, Susan Cuppett, Timothy Carr, Tommi Jones, Ruth Diedrichsen

Nebraska Swine Reports

Forty pigs (66.6 lb) were used in a 14-week 4-phase regime study conducted to evaluate the effect of feeding varying concentrations of DDGS to growing-finishing pigs formulated on a standardized ileal digestibility (SID) lysine (lys) basis, DDGS withdrawal at the last feeding phase, and ractopamine (RAC) supplementation 4 weeks prior to harvesting on carcass quality, and color stability and sensory characteristics of longissimus muscle (LM) of finishing pigs. Treatments consisted in 0, 15, or 40% dietary DDGS inclusion supplemented with or without RAC (4.5 ppm) 4 weeks prior harvesting. Final body weight, hot carcass weight, and dressing percentage were not …

Learning To Live Together: Mutualism Between Self-Splicing Introns And Their Hosts, Marlene Belfort, Venkata R. Chalamcharla, David R. Edgell

Biological Sciences Faculty Scholarship

Group I and II introns can be considered as molecular parasites that interrupt protein-coding and structural RNA genes in all domains of life. They function as self-splicing ribozymes and thereby limit the phenotypic costs associated with disruption of a host gene while they act as mobile DNA elements to promote their spread within and between genomes. Once considered purely selfish DNA elements, they now seem, in the light of recent work on the molecular mechanisms regulating bacterial and phage group I and II intron dynamics, to show evidence of co-evolution with their hosts. These previously underappreciated relationships serve the co-evolving …

Design And Synthesis Of Novel Agrofungicides Based On Naturally Occurring Pbdes, Robert Alexander Smith

Electronic Theses and Dissertations

Cyanobacterial symbionts of Indo Pacific marine sponges, e.g. Dysidea sp., produce hydroxylated (OH-) polybrominated diphenyl ethers (PDBEs) which likely function as chemical deterrents owing to their antifungal and antibacterial properties. Limiting the therapeutic potential and agricultural use of these antimicrobial natural products are the negative connotations associated with non hydroxylated anthropogenic PBDEs. Anthropogenic PBDEs are pervasive global pollutants used as flame retardant additives in many household goods, e.g. furniture, textiles, and electronics. These molecules have a propensity to bioaccumulate in living organisms, they easily traverse the trophic food chains, they are readily passed from mother to offspring, and many of …

The Role Of Policy And The Built Environment On Children's In-School Physical Activity In The Mississippi Delta, Abigail Gamble

Electronic Theses and Dissertations

School environments provide an ideal setting for children to develop and adopt active living behaviors as a way of life. The primary purpose of this investigation was to describe state, district and school level policy regarding in-school physical activity, the school built environment and in-school physical activity of children ages 6 through 11 years in the Mississippi delta. A mixed-methods approach was used to garner a rich understanding of how current policy and the built environment influence in-school physical activity and weight status. Eleven public schools in three districts representing two counties in the Mississippi delta participated in this investigation. …

Midwives Of Mississippi, Lane Noel

Electronic Theses and Dissertations

Across the United States as late as 1910, midwives delivered half of all babies. Their practice was primarily among women of white European descent and African American women of the South. The practice of midwifery was commonplace in Mississippi. Together, black midwives and white nurses would help to implement a new public healthcare structure in Mississippi during the 1920s. Records of the Mississippi State Board of Health together with letters from midwives and public health nurses' reports put midwives at the heart of the story of public health reform. Already held in high esteem by their own communities, midwives came …

Food And Identity: A Case Study Of Roman Soldiers And Native Civilians In Roman Britain, Aaron Michael Bobik

Electronic Theses and Dissertations

Food is a universal medium through which identity is expressed. In cultures both past and present, food represents a direct way to communicate many aspects of identity such as ethnicity, nationality, status, age, and gender. In archaeology, while the nutritional and economic roles of food have been a topic of study for decades, the relationship between food and identity is a research area largely in its infancy. In my thesis, I explore general aspects of identity in the past, and in particular, I utilize a case study of four archaeological sites (Segontium (Caernarfon), Portchester Castle, Wavendon Gate, and Dragonby) to …

Starved: Food Deserts In The Mississippi Delta, Novelette L. Brown

Electronic Theses and Dissertations

This thesis examines the impact of food deserts on obesity, and builds a case for additional research on rural food deserts independent from urban ones. The Mississippi Delta consistently presents the highest obesity rates within the state, yet both the third unhealthiest county (Quitman) and the healthiest (DeSoto) are located in that region. One of the reasons there is such a large discrepancy between the health rankings of DeSoto and Quitman counties is that DeSoto is contained within the Greater Memphis Metropolitan Area, but Quitman is entirely rural. Previous research has focused on the prevalence of urban food deserts and …

Good Neighbors: Agents Of Change In The New Rural South, 1900 To 1940, Thomas Wayne Copeland

Electronic Theses and Dissertations

This work paints an intimate portrait of rural people who lived in the hill counties of northeast Mississippi and southwest Arkansas between 1900 and 1940. Howard County, Arkansas and Union County, Mississippi serve as the representative counties for each hill-country region. Howard County is located in the foothills of the Ouachita Mountains, and Union County is located in the foothills of the Appalachian Mountains. This study identifies who in the rural communities was most responsible for bringing positive changes to their communities, questions what motivated their efforts, and evaluates their successes and failures. To this end, the work first examines …

The French Chef And The Cold War: Julia Child And The Mask Of Contained Domesticity, Hillary Ann Hamblen

Electronic Theses and Dissertations

Most scholarly studies and even general personal reflections about Julia Child portray her as a figure that changed the face of cooking, cookbooks, and cooking television for audiences of the late twentieth and twenty first centuries. While this is true, many of these studies and reflections do not acknowledge Child's ability to change mainstream ideas by conforming to some of them. While Child radicalized perceptions toward food and those who cook, she also represented a domestic woman and a wife. While Child's politics were indeed liberal, for the most part, her lifestyle was actually quite moderate. This project is an …

The Heavy Hand Of Government: An Economic Study Of Obesity, Kanybek Imanakovich Sagynbekov

Electronic Theses and Dissertations

Although there is extensive theoretical and empirical coverage of the incentive effect of an income tax on labor supply in the economics literature, there is no study of the secondary behavioral effects of an income tax. In this thesis, I explore the relationship among income, marginal income tax, and body weight. Namely, I show that under general conditions the Engel curve for the optimal weight is an inverted U-shaped function and the effect of the marginal income tax upon weight is non-linear. The empirical investigation uses two datasets: a panel dataset with 459 state-level observations for US states from 1992 …

Reforming Tastes: Taste As A Print Aesthetic In American Cookery Writing, Sarah Wurgler Walden

Electronic Theses and Dissertations

Many eighteenth-century philosophers such as Kant and Hume worked to develop discourses of taste as a means of standardizing cultural behaviors. Using physical taste as a metaphor for aesthetic perception and judgment, these writers could both define and abstract group boundaries. As American writers worked to distinguish their nation from their British forebears, many recognized the utility of taste-based discourse and worked to develop cultural tastes around shared principles of egalitarianism and democracy. Cookbooks and domestic writing soon engaged these discourses, as it was the task of women to cultivate a virtuous citizenry, and—through domestic print culture—to demonstrate the deleterious …

International Migration And Remittances: A Review Of Economic Impacts, Issues And Challenges From The Sending Country’S Perspective, Tereso S. Tullao Jr, Christopher James R. Cabuay

Angelo King Institute for Economic and Business Studies (AKI)

The paper reviews the motivations of people to migrate and remit as well as the impacts of migration and the effects of remittances. Reasons for migration are quite varied ranging from economic asymmetries (also known as push-pull factors), demographic asymmetries, investment in human capital, maximization of household income, the culture of migration, and the movement in natural persons. On the other hand, remittances are sent to the home country for altruistic, exchange, strategic and insurance motives as well as an arbitrage in interspatial differences in purchasing power. The impacts of migration and remittances are felt on both the household and …
