Validation Of Passive Air Sampling Monitors Onboard United States Navy Submarines, Larry A. Mcfarland

Community & Environmental Health Theses & Dissertations

An operating submarine creates a unique air quality mixture of compounds that result from a combination of human metabolism, construction materials, materials brought onboard and compounds created through the interaction of ship systems. A comprehensive study of submarine atmospheres is ongoing during deployments of U.S. Navy nuclear submarines. As part of the overall effort, a paired air sampling comparison field validation was conducted to compare the air sampling effectiveness of passive diffusive monitors compared to more traditional active air sampling methods when sampling for acrolein, formaldehyde and ozone in the enclosed submarine atmosphere. Acrolein monitors containing 2-hydroxymethylpiperidine (HMP) impregnated glass …

First Principles Of Physio-Informatic Systems: Neurocosmology, David Jay Warner

Loma Linda University Electronic Theses, Dissertations & Projects

Physio-informatics is a new systems model for linking human physiologic systems to information systems in the most general way. Physio-informatics is used here to denote a systems based, physiologically robust reference architecture for designing and refining interactive human-computer interface systems in ways that increase operational throughput of information. In this dissertation, a systems model for interactive human-computer interface systems is developed. This model is a physiologically based reference architecture for designing and developing interactive human computer interface systems to match the human nervous system’s ability to transduce, transmit, and render to consciousness the necessary information to interact intelligently with information. …

A Pharmacokinetic Study Of The Effects Of Stress On Chemical Exposure, Sierra H. Suhajda

Theses and Dissertations

Following the Gulf War there were many concerns raised about human exposure to the combination of chemicals and stress. Stress causes several changes in basic functions of a human body, from breathing and blood flow changes to hormonal and enzyme changes, and increased permeability of the blood-brain barrier. Each of these changes can strongly influence chemical uptake, distribution, and accumulation in the body. The purpose of this thesis was to model and predict the changes that will occur when stress is combined with chemical exposure. Physiologically-based pharmacokinetic (PBPK) modeling is one tool that can be used to visualize, predict, and …

The Use Of Animals In Higher Education: Problems, Alternatives, & Recommendations, Jonathan Balcombe

eBooks

Despite recent advances in technology and increasing societal concern for animals, animals continue to be exploited and killed in large numbers so that students can learn about their structure and function. Dissection may not be without its merits from an educational standpoint, if well implemented, but it appears from student surveys that it usually is not. When one considers the associated costs—animal suffering and death in the supply trade, disruption of wild animal populations, messages that tend to undermine rather than reinforce respect for life and concern for others, rising costs of animal carcasses (as compared with alternatives with longer …

Generation Of Human Chorionic Gonadotropin Beta Subunit Specific Monoclonal Antibody Using A Synthetic Peptide, Zhe Huang

Chemistry & Biochemistry Theses & Dissertations

Human chorionic gonadotropin (hCG) is well known for early immunological and bioassay tests for early detection of pregnancy. Since the hormone specific beta subunit confers unique biological and immunological specificity to hCG, immunochemical measurement of hCG has achieved greater specificity and sensitivity in recent years by using either the beta subunit as an immunogen or a partially reduced beta subunit polypeptide chain. However, antiserum raised against the entire hCG beta subunit usually cross-reacts to some extent with human luteinizing hormone (hLH). hCG has been found to be present in the extract of tumors and minute quantities of hCG are synthesized …

Evaluation Of Animal Welfare By The Self-Expression Of An Anxiety State, M. P. Carey, J. P. Fry

Assessment of Animal Welfare Collection

Although mental well-being has long been accepted as an important aspect of animal welfare, the subjective feelings of farm or laboratory animals are regarded as lying beyond the scope of scientific enquiry. We now report that pharmacological conditioning of pigs with a drug, pentylenetetrazole, known to induce anxiety in man, permits investigation of the presence or absence of this psychological state during exposure to a variety of environmental stimuli encountered during normal husbandry. Such pharmacological conditioning therefore provides a valuable means to assess and improve elements of animal welfare and should be applicable to other species that show operant behaviour.

The Nutritional Knowledge, Food Choices, And Exercise Habits Of Students At Langston University, Preston Solomon

McCabe Thesis Collection

The nutritional knowledge, food choice, and exercise habits of an individual determine his or her overall health and life expectancy. Information on these topics enables nutrition educators to develop strategies to improve knowledge and to tailor educational efforts which affect a large number of persons. Poor health in America today is an ever present reality. Heart disease, cancer, diabetes mellitus, cerebrovascular diseases, renal diseases, and pulmonary diseases are causes of death related in part to lack of nutritional knowledge and poor eating and exercise habits. A few of these diseases are chronic in nature and are the most deadly.

The Animal Research Controversy: Protest, Process & Public Policy, Andrew N. Rowan, Franklin M. Loew, Joan C. Weer

Experimentation Collection

The controversy today regarding the use of animals in research appears on the surface to be a strongly polarized struggle between the scientific community and the animal protection movement. However, there is a wide range of opinions and philosophies on both sides. Mistrust between the factions has blossomed while communication has withered. Through the 1960s, 1970s and early 1980s, the animal movement grew in numbers and financial resources, and developed much greater public recognition and political clout. The research community paid relatively little attention to the animal movement for much of this period but, alarmed by several public relations coups …

The Effect Of Insulin Mimetics On Enzymes Of Fatty Acid Biosynthesis, Eric A. Berg

Masters Theses

Fatty acid biosynthesis, an insulin regulated pathway, is the process of producing fatty acid chains from 2 and 3 carbon units. Two enzymes in this pathway that insulin affects are glucose-6-phosphate dehydrogenase (G6PDH) and fatty acid synthase (FAS). Sodium vanadate and sodium selenate have demonstrated insulin-like effects in several tissue and cell types. These mimetic effects include increasing glucose transport, regulating glycolytic enzymes, normalizing plasma glucose levels and activities of insulin regulated enzymes in diabetic rats. Our goal was to examine effects of sodium vanadate and sodium selenate on fatty acid biosynthesis in two insulin responsive systems: Isolated rat hepatocytes …

Development Of Periapical Lesions In Immunosuppressed Rats, Phillip A. Waterman Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

The pathogenesis of periapical lesions is the interaction of the oral flora with the existing host defenses. The role of bacteria has been established in endodontic disease but the contribution of the host defenses in periapical lesion formation is less clear. The purpose of this study was to compare periapical lesion development in immunosuppressed rats with that in normal rats. Thirty-five, eight-week old Sprague-Dawley rats were equally divided into seven groups. Groups 1, 2, and 3 were given weekly injections of Cytoxan, an immunosuppressive agent. Groups 4, 5, and 6 received no immunosuppressive therapy. Group 7 served as a control, …

Parasitology As An Interpretive Tool In Archaeology, Karl J. Reinhard

Karl Reinhard Publications

Parasitological studies of archaeological sites can be used to interpret past behavior and living conditions. During the 1980s problem-oriented research into prehistoric- and historical-period parasitism developed and resulted in thefield of archaeoparasitology. Archaeoparasitology attempts to integrate parasite data into archaeological theory and interpretation. Within the last decade, four major archaeoparasitological laboratories emerged. They developed interpretive frameworks that apply parasitological data to a remarkable variety of prehistoric behaviors. Parasite remains can be used to reconstruct aspects of diet, health, and other behaviors such as transhumance and trade. Finally. analysis of the distribution of parasite remains can be used to interpret aspects …

The Effects Of Ingested Carbonation On Oxygen Transport And Ventilation In Trained Distance Runners, Stacy Jean Ingraham

Dissertations and Theses @ UNI

The purpose of this study was to examine the effect of consumption of carbonated beverages on maximal aerobic capacity, as measured by maximal oxygen consumption (VO2MAX), and respiratory physiology, as measured by ventilation frequency (f), ventilatory equivalent for oxygen and carbon dioxide (O2VE, co2VE), expired minute ventilation (VE), carbon dioxide output (VCO2), respiratory exchange ratio (RER), and tidal volume (VT).

Thirteen male high school, collegiate and post collegiate distance runners from the local community performed two maximal treadmill tests exactly one week apart, following two different fluid ingestion treatments. The subjects were randomly assigned to a carbonated beverage or noncarbonated …

Evidence That A Major Portion Of Cellular Potassium Is "Bound", Ivan L. Cameron, W. Elaine Hardman, Keithley E. Hunter, Christine Haskin, Nancy K. R. Smith, Gary D. Fullerton

Scanning Microscopy

In this report we briefly review recent evidence which shows that a substantial proportion of intracellular K⁺ is "bound" or perturbed from the physicochemical properties expected in dilute aqueous solutions. In addition, we present evidence from electron probe x-ray microanalysis of thin cryosections of cells which indicates that the binding of K⁺ to anionic groups either carboxyl groups (HCO₂) on proteins or to phosphate groups in creatine phosphate (CrP) , in adenosine triphosphate, (ATP), in protein and in nucleic acids, are the main determinants of the maintenance of (as differentiated from the generated of) the well …

The Effect Of Horseback Riding Activity On The Tibialis Anterior, Vastus Lateralis, And Rectus Abdominis Of A Paraplegic, Laurie A. Price

Masters Theses

Horses are now being used in various programs under various conditions. The use of horses for therapy and recreation for the physically and mentally disabled first began in Germany and Switzerland. The United States now has many schools and different riding programs as well.

Riding seems to be especially beneficial to those with neurological impairments. Treatment of paraplegia is very limited but recreational activities are advancing. The use of the horse is beneficial for paraplegics emotionally as well as physically. Measurements and evaluations of these benefits are lacking. This project analyzes and measures the physical benefits of horseback riding on …

Can We Guarantee The Safety Of Genetically Engineered Organisms In The Environment?, Kathleen H. Keeler, Frances E. Sharples

School of Biological Sciences: Faculty Publications

Can we guarantee the safety of genetically engineered organisms in the environment? To anticipate my remarks, the answer to the title question is “No, we cannot guarantee the safety of genetically engineered organisms released into the environment.” Indeed, it is a tenet of the scientific method that nothing can be proved, only disproved. Thus, we can never show that a release will be safe. We could only show that it would be unsafe, if that were the case. However, if the question is posed differently, for example, can we safely release genetically engineered organisms into the environment?, the answer is …

Toward A Concise Definition And Perspective For Biology, Arthur V. Brown, Kristine Basinger Brown

Journal of the Arkansas Academy of Science

The content of introductory biology courses at the high school and college levels are currently being re-examined. Many biological educators favor revision of the high school biology courses to a format that directly addresses current social issues to "promote good citizenship". We believe it would be more meaningful to teach the fundamental principles of biology, the study of living systems. Properly defining biology, by defining a living system, should help identify important topics to include in a basic biology course. Emphasis should be placed on subjects which would contribute most to the development of a basic understanding of how all …

Seasonal Effects On Blood Pressure, David C. Dotson

Masters Theses

The relationship of seasons and blood pressure was investigated. The individuals in the sample groups were of two types: normal individuals and individuals who have been diagnosed as hypertensives and under medical supervision. This was a seasonal study? measurements were taken during midsummer and early fall, 1979. Factors constituting the variable for individual differences included: sex, age, genetic factors, diet, general body build and managerial vs, laborer workload.

Individual differences were controlled by use of a randomized complete block design with each individual constituting a block. Season was the treatment factor, and individual was the blocking factor. Measurements were taken …
