Hopf Bifurcation In Models For Pertussis Epidemiology, Herbert W. Hethcote, Yi Li, Zhujun Jing

Mathematics and Statistics Faculty Publications

Pertussis (whooping cough) incidence in the United States has oscillated with a period of about four years since data was first collected in 1922. An infection with pertussis confers immunity for several years, but then the immunity wanes, so that reinfection is possible. A pertussis reinfection is mild after partial loss of immunity, but the reinfection can be severe after complete loss of immunity. Three pertussis transmission models with waning of immunity are examined for periodic solutions. Equilibria and their stability are determined. Hopf bifurcation of periodic solutions around the endemic equilibrium can occur for some parameter values in two …

The Swift Rail Act: Will Sleepless Citizens Be Able To Quiet Train Whistles, And At What Cost?, Mark A. Gruenes

Northern Illinois University Law Review

Frustrated by the noise caused by train whistles, many Illinois municipalities have passed ordinances that ban trains from blowing their whistles at local crossings. Despite these local ordinances, however, railroads continue to instruct their engineers to sound whistles. Making matters worse for sleepless Illinois residents, the Federal Government entered the picture in 1994 when the Swift Rail Development Act of 1994 ("Swift Rail Act" or "Act") was made law. The Swift Rail Act directs the Secretary of Transportation ("Secretary") to promulgate regulations requiring trains to sound a "locomotive horn"' at all public highway-rail grade crossings. These regulations will preempt state …

Elderly Respondents' Perceptions Of Patronizing Speech By Service Providers Toward Elderly Adults., Tammi Rae La Tourette

Electronic Theses and Dissertations

This study examined the effects of several factors in elderly respondents' evaluations of neutral and patronizing speech by nurses toward elderly targets. Thirty-eight nursing home and 62 community Caucasian elderly women viewed two videotaped vignettes, one in which a nurse spoke to an elder target in a patronizing tone, and one with a neutral tone. Both samples rated the nurse more favorably, rated the elder target more satisfied with the conversation, and assumed that the nurse-elder dyad knew each other better when the nurse's speech was neutral as opposed to patronizing. Contrary to what was predicted, community elders did not …

A Comparative Gene Map Of The Horse (Equus Caballus), Alexandre R. Caetano, Yow-Ling Shiue, Leslie A. Lyons, Stephen J. O'Brien, Thomas F. Laughlin, Ann T. Bowling, James D. Murray

Biology Faculty Articles

A comparative gene map of the horse genome composed of 127 loci was assembled based on the new assignment of 68 equine type I loci and on data published previously. PCR primers based on consensus gene sequences conserved across mammalian species were used to amplify markers for assigning 68 equine type I loci to 27 horse synteny groups established previously with a horse-mouse somatic cell hybrid panel (SCHP, UC Davis). This increased the number of coding genes mapped to the horse genome by over 2-fold and allowed refinements of the comparative mapping data available for this species. In conjunction with …

Extensive Conservation Of Sex Chromosome Organization Between Cat And Human Revealed By Parallel Radiation Hybrid Mapping, William J. Murphy, Shan Sun, Zhang-Qun Chen, Jill Pecon-Slattery, Stephen J. O'Brien

Biology Faculty Articles

A radiation hybrid (RH)-derived physical map of 25 markers on the feline X chromosome (including 19 Type I coding loci and 6 Type II microsatellite markers) was compared to homologous marker order on the human and mouse X chromosome maps. Complete conservation of synteny and marker order was observed between feline and human X chromosomes, whereas the same markers identified a minimum of seven rearranged syntenic segments between mouse and cat/human X chromosome marker order. Within the blocks, the feline, human, and mouse marker order was strongly conserved. Similarly, Y chromosome locus order was remarkably conserved between cat and human …

The Role Of Brn-3.2 In Retinal Ganglion Cell Differentiation, Jerin Marie Wright

Loma Linda University Electronic Theses, Dissertations & Projects

Within the retina, the POU domain of transcription factors brn-3.0, brn-3.1, and brn-3.2 are present only in retinal ganglion cells. These genes are believed to be involved in establishing neural cell lineages in mammals. In this study brn-3.2 was examined by comparing the number of ganglion cells present during postnatal development in normal mice (+/+), in mice homozygous (-/-) for the brn-3.2 gene, and in adult mice with a heterozygous gene deletion (+/-) for brn-3.2. Optic nerve cross sections were imaged by electron microscopy, and axon profiles counted systematically by hand. These counts were then related to the nerve cross …

A Preclinical Model Of Ionizing Radiation And Tnf-Alpha Gene Therapy For Cancer, Jun Li

Loma Linda University Electronic Theses, Dissertations & Projects

Long term control of high-grade brain tumors is rarely achieved with current therapeutic regimens. This study sought to determine if pretreatment with plasmid DNA expressing Tumor Necrosis Factor-α (TNF-α) could enhance the effect of ionizing radiation in an aggressive, rapidly growing glioma tumor (C6) model. Plasmid DNA is an attractive vector system for delivery of foreign genes into eukaryotic cells due to its advantages including low immunogenicity in vivo, lesser toxicity and relatively low cost. We have constructed a plasmid-based mammalian expression vector (pGL1-TNF) to secrete human TNF-α from cancer cells. Plasmid DNA was successfully transfected into C6 cells …

Family And Child Psychosocial Functioning Of Infant Heart Transplant Recipients, Kimberly R. Freeman

Loma Linda University Electronic Theses, Dissertations & Projects

With the advancement of medical procedures, heart transplantation has become a viable alternative for infants born with congenital or acquired heart disease. Although these children are thought to experience much improvement in their overall physical functioning post-transplantation, the long-term psychological functioning of these children and their families is currently unknown. This study examines the long-term family functioning and psychosocial development of infant heart transplant recipients in comparison to children with congenital heart disease (CHD) and non-clinical control children. Results indicate that infant heart transplant recipients and their families experience fewer overall problems as compared to the CHD group, and more …

Structural Studies Of Recombinant Human Β-Casein Proteins, Yilin Hu

Loma Linda University Electronic Theses, Dissertations & Projects

β-Casein is the major component (~80%) of the human casein system. Interacting with calcium and phosphates through its phosphorylated N-terminus, β-casein participates in the formation of micelles which carry these otherwise insoluble nutrients indispensable for the growth and development of newborns. Human β-casein, or fragments thereof, are also found to have biological effects such as enhancement of calcium absorption. So far, knowledge of micelle formation is limited and structural studies of β-casein, especially its N-terminal portion will provide a better understanding of the structure-function relationship of milk micelles.

To elucidate the role that the N-terminus of the protein plays in …

Effect Of Pollution On Genetic Diversity In The Southern California Bight, Xiao Li Ma

Loma Linda University Electronic Theses, Dissertations & Projects

Two intertidal invertebrate species, M galloprovincialis and Balanus glandula, were collected from seven different bay sites along the Southern California coast to test if environmental contamination is associated with the decrease of genetic diversity at the population level. Collections were made at three relatively pristine "clean" sites and four "impacted" sites which were exposed to heavy industrial or boating activity and which had previously, been identified as having measurable levels of pollution. The "Comet" assay (Single Cell Gel electrophoresis) was performed to measure single-strand DNA breaks in mussels at several of the sites in order to confirm differing impacts …

Birth Cohort Differences In Features Of Antisocial Alcoholism Among Men And Women, S. F. Stoltenberg, E. M. Hill, S. A. Mudd, F. C. Blow, R. A. Zucker

Department of Psychology: Faculty Publications

Background: This study examines the relations between birth cohort, gender, and family history of alcohol problems on alcohol dependence, and on the endorsement of alcohol abuse/dependence symptoms related to antisocial behavior. Methods: Men (n = 1365) and women (n = 625) were recruited from the community, hospitals, and other treatment sites and were given a structured diagnostic interview. Data were analyzed by using logistic regression. Results: Age of first regular alcohol use was lower in more recent birth cohorts for both men and women, with those born in the most recent cohort reporting earliest regular use. The decline …

The Offense: Interpreting The Indictment Requirement In 21 U.S.C. § 851, Christopher Serkin

Michigan Law Review

Congress enacted the Comprehensive Drug Abuse Prevention and Control Act of 1970 ("the Act") to unify and rationalize its treatment of drug offenses. The Act was an enormous piece of legislation, requiring months of congressional hearings before it was passed. Today, the Act encompasses over 150 sections of title 21 of the U.S. Code and regulates behavior ranging from manufacturing and mislabeling to prescribing controlled substances. Like any piece of complex legislation, the Act has spawned its share of litigation. One controversy has defied satisfactory resolution: the meaning of the innocuous phrase, "the offense," in section 851(a)(2). The statute's structure …

The Effect Of Divalent Cations On The Prophenoloxidase Enzyme Cascade Activity In The Freshwater Crayfish Cambarus Latimanus, Hans Skailand Eikaas

Theses and Dissertations

The effect of divalent cations such as cadmium, calcium, copper, lead and magnesium upon the prophenoloxidase system (proPO) was studied in hemocytes of the crayfish Cambarus latimanus. It was demonstrated that cadmium, calcium, copper and lead increased proPO activity significantly, whereas magnesium had no statistically significant effect on the system. Also, the molecular weight of the proPO enzyme was estimated using SDS-PAGE and found to be approximately 76 kDa.

The Effect Of Pain Management Education On Nurses' Knowledge And Attitudes Regarding Opioids And Adjuvants, Lynne Hopper Mccoy

Master's Projects

The purpose of this research was to determine if a pain management class improved nurses' knowledge and influenced nurses' attitudes regarding pain management. The design was quasi-experimental using pretest-posttest intervention. 83 participants completed the Nurses Knowledge and Attitude Survey Regarding Pain twice. Those who attended a class showed improvement in their pain management knowledge and attitude scores on the survey. Implications for staff development and inservice educators are that continuing education increases nurses knowledge about pain management and must include opportunities for class members to apply concepts.

Evaluation Of The Effectiveness Of A Health Education Program For Classroom Assistants, Patricia A. Robinson

Master's Projects

Classroom Instructional Assistants are being used more frequently to provide care for medically fragile children who are mainstreamed into the regular education setting. The purpose of this evaluative study was to develop a beginning health curriculum that could be provided as an inservice program for classroom Instructional Assistants. Content for the inservice consisted of handwashing, medication administration, asthma, and seizures. This study used a pretest and posttest design to look at the effectiveness of the educational inservice. There were 17 participants, 16 of whom completed the pretest and posttest. A pretest was administered prior to the inservice followed by a …

Differentiation In Roles Of School Nurse And Unlicensed Assistive Personnel, Lynn Shieh

Master's Projects

School nurses provide a vast number of health services for students, teachers, and staff. Despite school nurses' important contributions to the health status of students, through the years their positions have been gradually supplemented by Unlicensed Assistive Personnel (UAP)/ Health Clerks. With the number of UAPs increasing in the school setting, roles and responsibilities of school nurses and UAPs need to be clearly differentiated in order to utilize the UAP's services legally and efficiently. This research used a descriptive survey to investigate the perceptions that differentiate the role of school nurses and UAPs among school administrators, nurses, UAPs, secretaries, and …
