Messenger Rna Half-Life Measurements In Mammalian Cells, Chyi-Ying A Chen, Nader Ezzeddine, Ann-Bin Shyu

Faculty, Staff and Student Publications

The recognition of the importance of mRNA turnover in regulating eukaryotic gene expression has mandated the development of reliable, rigorous, and "user-friendly" methods to accurately measure changes in mRNA stability in mammalian cells. Frequently, mRNA stability is studied indirectly by analyzing the steady-state level of mRNA in the cytoplasm; in this case, changes in mRNA abundance are assumed to reflect only mRNA degradation, an assumption that is not always correct. Although direct measurements of mRNA decay rate can be performed with kinetic labeling techniques and transcriptional inhibitors, these techniques often introduce significant changes in cell physiology. Furthermore, many critical mechanistic …

The Role Of Sse1 In The De Novo Formation And Variant Determination Of The [Psi+] Prion, Jaou-Chen Huang

Faculty, Staff and Student Publications

In several species, a family of nuclear receptors, the peroxisome proliferator-activated receptors (PPARs) composed of three isotypes, is expressed in somatic cells and germ cells of the ovary as well as the testis. Invalidation of these receptors in mice or stimulation of these receptors in vivo or in vitro showed that each receptor has physiological roles in the gamete maturation or the embryo development. In addition, synthetic PPAR gamma ligands are recently used to induce ovulation in women with polycystic ovary disease. These results reveal the positive actions of PPAR in reproduction. On the other hand, xenobiotics molecules (in herbicides, …

Genes In Glucose Metabolism And Association With Spina Bifida, Christina M Davidson, Hope Northrup, Terri M King, Jack M Fletcher, Irene Townsend, Gayle H Tyerman, Kit Sing Au

Faculty, Staff and Student Publications

The authors test single nucleotide polymorphisms (SNPs) in coding sequences of 12 candidate genes involved in glucose metabolism and obesity for associations with spina bifida. Genotyping was performed on 507 children with spina bifida and their parents plus anonymous control DNAs from Hispanic and Caucasian individuals. The transmission disequilibrium test was performed to test for genetic associations between transmission of alleles and spina bifida in the offspring (P < .05). A statistically significant association between Lys481 of HK1 (G allele), Arg109Lys of LEPR (G allele), and Pro196 of GLUT1 (A allele) was found ( P = .019, .039, and .040, respectively). Three SNPs on 3 genes involved with glucose metabolism and obesity may be associated with increased susceptibility to spina bifida.

Predation By Crabs On Rocky Shores In North-East Atlantic, Ana Catarina Ferreirada Silva

School of Biological and Marine Sciences Theses

Highly mobile predators are known to have an important influence on shallow-water habitats. There is, however, little information about the role of crabs on the ecology of rocky shores. Here I examine the extent and consequences of predation by crabs on shores in the North-East Atlantic. The specific aims of this thesis are to: investigate spatial variation in use of the intertidal by crabs along a horizontal gradient of exposure to wave action and a vertical gradient of tidal elevation; assess their use of the intertidal as a feeding area by examining stomach content composition; examine the extent of connectivity …

Linking Biotic Activity To Ecosystem Functioning, Jeanette Sanders

School of Biological and Marine Sciences Theses

The central theme of this thesis was the search for ecologically meaningful ways to quantify the relationships between the biota and ecosystem processes. This thesis investigated whether a "functional group" approach, that characterised the fauna according to similarities in their activities, could be successfully employed to quantifiably link species' performance to important ecosystem processes. Initially the abilities of traditional "trophic" and "bioturbatory" categories to characterise the estuarine macrobenthic fauna and discriminate between estuarine sites were examined. This thesis determined that the perceived inter-site similarity within an estuary varied according to the function being investigated and that the apparent associations between …

Demography And Genetic Diversity Of The Mexican Black Iguana Ctenosaura Pectinata, Victor Aguirre-Hlidalgo

School of Biological and Marine Sciences Theses

The hunting of the black iguana (Ctenosaura pectinata) in some regions of Mexico constitutes an acute problem because mature, gravid females arc killed and eaten just before they lay their eggs. This practice thus impacts both the survival of adults and the otherwise imminent recruitment of new individuals to the population. The objective of this project was to compare the demographic behaviour and the genetic variability of two population of the black iguana, one protected and one subject to hunting. This information allowed us to project their population dynamics and investigate the likely population-level consequences of hunting. A clear difference …

Developmental Sequences In Freshwater Pulmonate Gastropods, Jennifer J. Smirthwaite

School of Biological and Marine Sciences Theses

The main aims of this thesis were to develop an integrative approach (i.e. one that included physiological as well as traditional morphological events) that allowed the construction of "timelines" of event sequences during development for pulmonate gastropods and to investigate how these sequences varied between (heterochrony) and within (heterokairy) species. Detailed descriptions of development in twelve species from three families (Lymaeidae, Planorbidae and Physidae) highlighted several heterochronies that were confirmed by a phylogenetically explicit analysis (PARSIMOV). These heterochronies involved physiological events (i.e. the first heart beat, appearance of the eye, body flexing, mantle muscle activity, attachment to egg capsule and …

Software Curating : The Politics Of Curating In/As (An) Open System(S), Joasia Krysa

School of Biological and Marine Sciences Theses

The thesis examines how Information technologies have changed the practice of curating. It proposes an Interdisciplinary approach that directly links curating (often understood as an activity of artistic programming), computing (the activity of computer programming) and a relatively recent Interest In software art (in which programming Is understood as artistic practice). Although there Is much contemporary critical work and practice that Is described as art-oriented programming or software art, the thesis aims to explore a perceived gap In discussions around software curating. Curators working with online technologies are presented with the challenge of how to respond to new artistic forms …

Factors Affecting The Production Of Fermented Moist Feed For Chickens And Effects On The Gastrointestinal Environment, Aziwo Tatanja Niba

School of Biological and Marine Sciences Theses

Fermented feed technology is a biosafe method of feed preparation and fermentation improves feed quality. Factors affecting lactic acid production in fen-nented moist feed for chickens and the influence of fermented feed on the gastrointestinal environment of chickens were investigated. Water quality was observed to affect lactic acid production in fermentation of cereals (maize, sorghum, wheat and barley). The presence of calcium carbonate in the fermentation mixture significantly (P<0.01) reduced lactic acid production from maize, sorghum and wheat. Grain particle size did not significantly affect feed fermentation as biosafe concentrations of lactic acid (>150mmol/L) were obtained from fermentation of coarse grain particle sizes. Differences in polyphenols content of red and white sorghum varieties did not have a significant effect on 24-hour lactic acid production …

The American Public's View Of Congress, John R. Hibbing, Christopher W. Larimer

Department of Political Science: Faculty Publications

Congress has long been unpopular with the American public, with approval numbers above fifty percent serving as the exception rather than the norm. In this essay we argue that such disapproval stems not from calculated reaction to policy outcomes or partisan attachments. Rather, people tend to disapprove of Congress for exactly the thing it was designed to be: an open and deliberative lawmaking body. The more Congress does its job, the more the public tends to disapprove.

The Reflexivity Of Pain And Privilege: An Autoethnography Of (Mestizo) Identity And Other Mestizo Voices, Ellis Hurd

Dissertations and Theses @ UNI

Approximately 20 million Latinos living in the United States identify as Mestizos. A Mestizo is a person of mixed heritage. Almost half of these Mestizos racially or culturally identify as White, while the other half identify as Hispanic or racially mixed. These racial and cultural identifications have vast effects on educational performance: those identifying themselves as Hispanic or mixed experience lower academic achievement whereas those identifying as White do not. Many communities have experienced an influx of Mestizo-Latinos, but are ill prepared for the educational challenges due to the language and cultural differences Mestizos bring. This researcher himself has experienced …

This Response addresses the criticisms of our project by Professors Rick Hills and Michael O'Hear. Before we address those challenges, we first want to reiterate our gratitude to the B.U. Law Review for hosting an exchange based on our article, Punishing Family Status (forthcoming BU LR, December 2008), and to Professors Hills and O'Hear for their careful and subtle analysis of that article. Additionally, it's worth recapitulating what our bottom-line conclusions are so we can better see if there are any practical disagreements with our critics. Summarizing quickly: we support decriminalization in the cases of parental responsibility laws (based on …

A Prescription For Racial Equality In Medicine, Barbara A. Noah

Faculty Scholarship

A significant body of evidence suggests that minority race adversely affects the quantity and quality of health care provided to minority patients. Although no one has documented systemic overt racism among health care providers, persistent inequities in the delivery of health care services pose serious problems for patients of color. Ultimately, the medical establishment must confront the reality that African Americans and other racial minorities often do not receive equal treatment in the health care system.

The continued implementation of affirmative action programs as part of the medical school admissions process plays a key role in improving health care delivery …

A Comparison Of The Portrayal Of Evil In Fairy Tales And Contemporary Fantasy Fiction, Donna Gwinnup

Graduate Research Papers

Writing and publishing literature for children and young adults has become a rhizomorphic entity. There are thousands of books published each year. When you compare that to the little over two hundred stories Perrault and the Grimm brothers recorded you can see how the market has substantially grown. With the use of literature as a teaching tool it is imperative we keep a close watch on trends. This study was designed to look at the changes from fairy tales to contemporary fiction in order to ascertain what changes have taken place in three particular areas: has the gender of the …

Going Beyond Cookbook Labs : Computer-Based Laboratory Tools In The High School Physics Classroom, Jennifer A. Strohbehn

Graduate Research Papers

Physics education is currently undergoing a face lift. The lecture should no longer be the primary mode of instruction because students are not actively participating. For effective learning to occur, the students need to be engaged, not passive listeners (Knight, 2005). Student-centered classrooms are becoming more common, but there is still work to be done. For a student-centered classroom to be effective, the students must construct their own understanding with the teacher acting as a 'guide. Physics instructors are responsible .for .making the classroom a user friendly environment for students to explore the basic concepts of physics and to develop …

Motivating Middle Level Students : Strategies To Help Reach And Teach Middle Level Students, Lisa L. Munsey

Graduate Research Papers

This review of literature focused on the strategies educators use for motivating the young adolescent in the middle level classroom.

Anderman and Maehr (1994) found motivation could be improved through a variety of methods by focusing on specific areas: developmental changes, intrinsic versus extrinsic, middle level transformation and classroom practice. Along these same lines, Curwin (2006) found motivation can be enhanced with practices in the middle level classroom through four main areas: (1) welcoming students to school and class, (2) stressing the effort students put forth, (3) increasing homework completion, and (4) turbo charging classroom lessons.

This paper focused on …

Music And The Brain, Kimberly D. Madison

Graduate Research Papers

A great deal of literature focuses on the subject of music and the brain and how music can affect learning. Music stimulates brain patterns, and therefore should be considered essential in an academic setting. This review was written to provide an analysis of the published literature and studies in the area of music and cognitive development, to examine how the brain is wired for music, and to determine whether music is an effective tool in enhancing environmental and cognitive learning conditions in classrooms.

Amp-Activated Protein Kinase Is Involved In Hormone-Induced Mouse Oocyte Meiotic Maturation In Vitro, Jing Chen, Stephen M. Downs

Biological Sciences Faculty Research and Publications

We have previously shown that AMP-activated protein kinase (AMPK) can induce the resumption of meiosis in mouse oocytes maintained in meiotic arrest in vitro. The present study was carried out to determine whether AMPK activation is involved in hormone-induced maturation. Follicle-stimulating hormone (FSH) and the EGF-like peptide, amphiregulin (AR), are potent inducers of maturation in cumulus cell-enclosed oocytes (CEO). Within 3 h of FSH treatment, phospho-acetyl CoA carboxylase (ACC) levels were increased in germinal vesicle (GV)-stage oocytes when compared to non-stimulated controls and remained elevated throughout 9 h of culture, indicating AMPK activation. A similar response to AR was observed …

Off-Label Psychopharmacologic Prescribing For Children: History Supports Close Clinical Monitoring., Julie M Zito, Albert T Derivan, Christopher J Kratochvil, Daniel J Safer, Joerg M Fegert, Laurence L Greenhill

Department of Psychiatry and Human Behavior Faculty Papers

The review presents pediatric adverse drug events from a historical perspective and focuses on selected safety issues associated with off-label use of medications for the psychiatric treatment of youth. Clinical monitoring procedures for major psychotropic drug classes are reviewed. Prior studies suggest that systematic treatment monitoring is warranted so as to both minimize risk of unexpected adverse events and exposures to ineffective treatments. Clinical trials to establish the efficacy and safety of drugs currently being used off-label in the pediatric population are needed. In the meantime, clinicians should consider the existing evidence-base for these drugs and institute close clinical monitoring.
