Cytokine Expression By T. Helper Cells Responding To Stress, Dina Zanetti

Master's Theses

Stress causes alterations to the immune system. These alterations have lead to increased susceptibility to antigens. The present study explores shifts in T helper (TH) cell balance (TH1 and TH2), through their cytokine expression. This study was performed in three phases, and focused mainly on animals subjected to a 10 day a chronic unpredictable stress paradigm. Phase one used ELISAs to confirm the cytokine profile produced from TH 1 and TH2 murine cell-lines. Phase two used SDS PAGE and Western Immunoblotting to show that splenocytes from Long Evan's Hooded rats subjected to the stress paradigm, had decreased in intercellular in …

Do Cellular Phones Cause Headaches?, Jasmine Gay

McCabe Thesis Collection

Many people have recently complained about experiencing headaches in association with the use of their cellular telephones. There is much controversy over this subject because it has not yet been proven that the microwaves emitted by cellular telephones cause headaches. The research questions include the following: What are the effects, if any, of the use of cellular telephones on human health? Do they cause headaches? Are they responsible for the increase in size of some brain tumors?

There have been many experiments performed by various scientists in the field of bioelectromagnetics and by the World Health Organization (WHO); however, these …

Variations In The Histamine Content Of Mink Testes Due To Injections Of Gonadotrophic Hormones And Application Of Free Radicals In Vitro, Grant I. Wilson

Biology

It was hypothesized that gonadotropic hormones and oxygen-derived free radicals affect histamine production in the testes. Luteinizing hormone, follicle stimulating hormone, prolactin, a combination of these three hormones, or saline (controls) were injected for either 4 or 7 days into seven wild-type (demi) and seven dark male mink per group. All mink were euthanized with carbon monoxide. Their testes were removed and frozen on dry ice. The histamine content was analyzed using radioimmunoassay. The control wild-type mink injected for either 4 or 7 days had histamine values of 8.15 μg/g and 7.56 μg/g, respectively. In wild-type mink, there was no …

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 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 …

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 …

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 …

The Spleen Of The Frog, Clifford F. Moran

Bachelors’ Theses

Although we of today are living In a relatively advanced state of civilization, there still remains to be solved by man many familiar mysteries. These are found not only in the physical order but in the chemical and biological as well. It seems that the greater strides man takes toward the solution of his difficulties, the more other ones crop up to plague him. With the conquering of such deadly diseases as Diphtheria, Malaria and Scarlet Fever, man once dared to dream about a universe free from sickness. Yet today we find that three others have arisen which are causing …

The Spleen Considered With Special Reference To Its Physiology, Frank A. Dolce

Bachelors’ Theses

The aim of this essay on the structure and function of the spleen is to bring together in somewhat concise form all the available knowledge concerning this organ up to the present moment. However, time and the difficulty of obtaining valuable articles has limited this essay considerably. The first few pages while not giving a very detailed historical background may be considered quite adequate for the purpose intended. The evolutionary development of the spleen is here considered in broad outline. The microscopic anatomy of the spleen and its function in relation to the blood have been considered in greater detail …
