Dental Hygiene Participation In Managing Incipient And Hidden Caries, Caren M. Barnes

College of Dentistry: Faculty Publications

The essence of dental hygiene practice includes the use of preventive and therapeutic methods for the promotion of good health and to prevent and control oral diseases. Dental hygienists actively promote the prevention of oral diseases through patient education that encourages self-care prevention of dental caries, supplemented by needs-related professional preventive services. Equally significant in the scope of dental hygiene practice are thorough oral examinations for disease detection. Although dental hygienists do not legally or definitively diagnose dental caries, they are responsible for detecting caries at all stages of the disease, recognizing caries risk factors, and planning management strategies. Because …

Does Choice Of Estimators Influence Conclusions From True Metabolizable Energy Feeding Trials?, Mark H. Sherfy, Roy L. Kirkpatrick, Kenneth E. Webb Jr.

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

True metabolizable energy (TME) is a measure of avian dietary quality that accounts for metabolic fecal and endogenous urinary energy losses (EL) of non-dietary origin. The TME is calculated using a bird fed the test diet and an estimate of EL derived from another bird (Paired Bird Correction), the same bird (Self Correction), or several other birds (Group Mean Correction). We evaluated precision of these estimators by using each to calculate TME of three seed diets in blue-winged teal (Anas discors). The TME varied by <2% among estimators for all three diets, and Self Correction produced the least variable TMEs for each. The TME did not differ between estimators in nine paired comparisons within diets, but variation between estimators within individual birds was sufficient to be of practical consequence. Although differences in precision among methods were slight, Self Correction required the lowest sample size to achieve a given precision. Feeding trial methods that minimize variation among individuals have several desirable properties, including higher precision of TME estimates and more rigorous experimental control. Consequently, we believe that Self Correction is most likely to accurately represent nutritional value of food items and should be considered the standard method for TME feeding trials.

Orientation To Nutrition Care Process Standards Improves Nutrition Care Documentation By Nutrition Practitioners, Nancy Hakel-Smith, Nancy M. Lewis, Kent M. Eskridge

Department of Nutrition and Health Sciences: Faculty Publications

Preparing Teachers To Create A Mainstream Science Classroom Conducive To The Needs Of English-Language Learners: A Feminist Action Research Project, Gayle A. Buck, Colette Mast, Nancy Ehlers, Elizabeth Franklin

Department of Teaching, Learning, and Teacher Education: Faculty Publications

A feminist action research team, which consisted of a science educator, an English-language learner (ELL) educator, a first-year science teacher, and a graduate assistant, set a goal to work together to explore the process a beginning teacher goes through to establish a classroom conducive to the needs of middle-level ELL learners. The guiding questions of the study were answered by gathering a wealth of data over the course of 5 months and taken from the classroom, planning sessions, and researchers and students. These data were collected by observations, semistructured interviews, and written document reviews. The progressive analysis ultimately revealed that: …

Women In Agriculture: Making The Critical Difference, Meg Klosterman Kester

Cornhusker Economics

In 2002 the Census of Agriculture reported the total number of farm operators was 70,668. Nearly 16,000 of those operators were women, representing 22.5 percent of all operators. Over 3,000 women were designated as principal operators, representing over 6 percent of Nebraska’s 49,355 farms. Because women play a significant role in farm operation in the state, the Women in Agriculture program has grown and flourished over the past 21 years.

Biotinylation Of K12 In Histone H4 Decreases In Response To Dna Double-Strand Breaks In Human Jar Choriocarcinoma Cells1,2, Nagarama Kothapalli, Gautam Sarath, Janos Zempleni

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

We tested the hypothesis that biotinylation of K12 in histone H4 plays a role in the cellular response to double-strand breaks (DSB) of DNA in human cells. DSB were caused by treating choriocarcinoma JAr cells with etoposide. Biotinylation of K12 in histone H4 decreased by 50% as early as 10–20 min after initiation of treatment with etoposide. Biotinylation returned to initial levels 30–40 min after the addition of etoposide to the medium. Temporal patterns of K12-biotinylation were similar for human lymphoma cells. Phosphorylation of S14 of histone H2B and poly(ADP-ribosylation) of glutamate residues on histone H2A are known markers of …

Rose Productivity And Physiological Responses To Different Substrates For Soil-Less Culture, C. Samartzidis, Tala Awada, E. Maloupa, K. Radoglou, H.-I. A. Constantinidou

School of Natural Resources: Faculty Publications

Cultivation of roses in various soil-less media was studied with the aim to identify the optimum soil condition for rose production. Madelon roses grafted on rootstock of Rosa indica var. major were transplanted to polyethylene bags containing zeolite and perlite (at ratios of 25z:75p, 50z:50p, 75z:25p and 100z:0p, v/v) in a climate-controlled greenhouse. Net photosynthesis (A_net), stomatal conductance (g_s) and water use efficiency (WUE) of roses were followed for 5 months. Flower production and quality were recorded in three flowering flushes during a 5-month period. Analysis of variance of repeated measurements showed that even …

Normal Hematologic And Biochemical Values For Prelaying Greater Sage Grouse (Centrocercus Urophasianus) And Their Influence On Chick Survival, Mike R. Dunbar, Michael A. Gregg, John A. Crawford, Mark R. Giordano, Susan J. Tornquist

United States Department of Agriculture Wildlife Services: Staff Publications

Declines in greater sage grouse (Centrocercus urophasianus) productivity and population numbers throughout their range demand a better understanding of how nutrition influences sage grouse populations. During March and April 1999–2001, blood samples were collected from 158 female (73 adult, 85 yearling), free-ranging, prelaying, greater sage grouse from an area in northwestern Nevada, USA, and southeastern Oregon, USA. These blood samples were evaluated to establish normal blood values for sage grouse and ascertain if certain blood parameters, as indices of nutrition, are useful for predicting if sage grouse hens would raise at least one chick to 1 August. Results of logistic …

Effects Of Summer Grazing Strategies On Organic Reserves And Root Characteristics Of Big Bluestem, E. M. Mousel, Walter H. Schacht, C. W. Zanner, Lowell E. Moser

Department of Agronomy and Horticulture: Faculty Publications

Quantifying root structure response to multiple defoliation events in a grazing situation is critical in developing management plans for warm-season tall grasses. A pasture experiment was conducted in 1999, 2000, and 2001 near Mead, NE. The objective of the experiment was to determine the effect of timing and frequency of grazing on big blue- stem (Andropogon gerardii Vitman) etiolated tiller growth and root and rhizome structure. Paddocks were grazed at a stocking rate of 9.9 Animal Unit Month (AUM) ha^-1 in two to four cycles from mid-May to early-September. In April 2002, five 6.6- 132-cm soil cores were …

K4, K9 And K18 In Human Histone H3 Are Targets For Biotinylation By Biotinidase, Kenya A. Kobza, Gabriela Camporeale, Brian Rueckert, Alice Kueh, Jacob B. Griffin, Gautam Sarath, Janos Zempleni

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

Histones are modified post-translationally, e.g. by methylation of lysine and arginine residues, and by phosphorylation of serine residues. These modifications regulate processes such as gene expression, DNA repair, and mitosis and meiosis. Recently, evidence has been provided that histones are also modified by covalent binding of the vitamin biotin. The aims of this study were to identify biotinylation sites in histone H3, and to investigate the crosstalk among histone biotinylation, methylation and phosphorylation. Synthetic peptides based on the sequence of human histone H3 were used as substrates for enzymatic biotinylation by biotinidase; biotin in peptides was probed using streptavidin peroxidase. …

Trace Elements Status Of White-Tailed Deer (Odocoileus Virginianus) And Moose (Alces Alces) In Nova Scotia, Beth Pollock

Canadian Cooperative Wildlife Health Centre: Newsletters and Publications

The province of Nova Scotia is considered to have two moose (Alces alces) populations. In 2003, the moose of the mainland area of the province were formally listed “ENDANGERED” under the Nova Scotia Endangered Species Act. To date, the specific causes of the Mainland moose population decline have not been determined. Trace element imbalances have been considered as a potential etiology for the population decline. Liver and kidney samples were collected from white-tailed deer (Odocoileus virginianus) and moose throughout Nova Scotia during the fall and winter 2000-01 to compare trace element concentrations between the two species, in relation to age, …

Expression Analysis Of Gnrh Responsive Anterior Pituitary Genes In Lines Of Swine Divergent For Ovulation Rate, Benjamin E. Bass

Department of Animal Science: Dissertations, Theses, and Student Research

The interaction of GnRH with its receptor represents a crucial point for control of reproduction. Additionally, the porcine GnRH receptor (GnRHR) gene is a positional candidate for genes influencing reproductive efficiency, residing in a similar chromosomal region as a QTL for ovulation rate (OR). Gonadotropic gene expression in lines of swine divergent for OR may provide insight into the phenomena of increased litter size. Chinese Meishan (OR=14.5), a white crossbred line selected based on an index of OR and embryonic survival (OR=17.8), and a Control line (OR=13.2) were evaluated. Following three (Index and Control) or six (Meishan) estrous cycles, gilts …
