Birds Of Lake Mcconaughy And The North Platte River Valley, Oshkosh To Keystone, Richard C. Rasche, Paul A. Johnsgard
Nebraska Bird Review
Cedar Point Biological Station was established in 1975 at a site approximately one mile below Kingsley Dam in Keith County, Nebraska. Since that time, summer ornithology classes have been periodically offered beginning in 1977 when it was taught by Dr. Stephen Fretwell. A variety of ornithologists have kept records of the summer birds of the area. Beginning in 1970, when he first visited the area, the senior author has accumulated a large amount of data covering all seasons of the year, which form the primary basis for the seasonal information in this paper. In addition, much information was contributed by …

Prospects For The Medical Use Of Interferon In 1984, Bosko Postic, Julio C. Arroyo
Prospects For The Medical Use Of Interferon In 1984, Bosko Postic, Julio C. Arroyo
Henry Ford Hospital Medical Journal
Interferon, a natural and wide spectrum antiviral polypeptide that was discovered in 1957, has been extensively described. In addition to its antiviral effect, interferon has been found to suppress tumor growth and modulate the immune response. Until 1980, interferon was primarily prepared for clinical trials in human leukocytes derived from the buffy coat of whole blood. A major breakthrough occurred in the late 1970s when human interferon was produced by DNA recombinant methods in such heterologous cells as bacteria (genetic engineering). Interferon is not commercially available in 1984, but it may, based on clinical trials in humans, become part of …

Functional Cranial Analysis Of Large Animalivorous Bats (Microchiroptera), Patricia W. Freeman
Functional Cranial Analysis Of Large Animalivorous Bats (Microchiroptera), Patricia W. Freeman
University of Nebraska State Museum: Mammalogy Papers
Large animalivorous bats include carnivorous, piscivorous and insectivorous microchiropterans. Skull proportions and tooth morphology are examined and interpreted functionally. Four wide-faced bats from four families are convergent in having wide skulls, large masseter muscle volumes and stout jaws, indicating a powerful bite. Three of the four also have long canine teeth relative to their maxillary toothrows. Carnivorous bats have more elongate skulls, larger brain volumes and larger pinnae. The wide-faced bats are all oral emitters and have heads positively tilted relative to the basicranial axis. The carnivorous species are nasal-emitting bats and have negatively tilted heads. The orientation of the …
The Effects Of Maternal Administration Of Methadone On Beta-Endorphin Content In The Brain And Pituitary Of The Rat Progeny, Randall L. Braun
The Effects Of Maternal Administration Of Methadone On Beta-Endorphin Content In The Brain And Pituitary Of The Rat Progeny, Randall L. Braun
Loma Linda University Electronic Theses, Dissertations & Projects
Methadone is often used in the maintenance and detoxification of opioid-dependent pregnant women. This use of methadone during pregnancy is known to be associated with teratogenic effects observed in the progeny. The present study is an attempt to gain insight into possible pathophysiologic mechanism(s) responsible for these teratogenic effects: specifically, a relationship between maternal methadone administration and the content of the endogenous opioid peptide, beta-endorphin, in the brain and pituitary of the rat progeny.
In brief, nulliparous mature female Sprague-Dawley rats received daily injections (5 mg./kg.) of methadone hydrochloride (methadone-treated) or a similar volume of physiological saline (controls), treatment started …

The Effect Of Dietary Alpha - Linolenic Acid On Apparent Risk Factors Of Cardiovascular Disease, Kelvin D. Lindbeck
Loma Linda University Electronic Theses, Dissertations & Projects
Eight healthy male lacto-ovo-vegetarian subjects averaging 28.0 ± 3.6 years of age (22 to 53 years) were fed a diet rich in α-linolenic acid (18:3 ω 3) for four weeks. Arterial blood pressure and body weight were recorded each week. Plasma 6-keto-prostaglandin F1α (6-keto- PGF1α ), thromboxane B2 (TXB2), total cholesterol, triglyceride, and total phospholipid fatty acid composition were analyzed at 0, 2 and 4 weeks.
Systolic blood pressure increased significantly between weeks 0 and 1 (106.5 ± 2.7 mmHg to 114.0 ± 3.7 mmHg; p < 0.003), but decreased to 107.3 t 2.6 mrHg (p < 0.02) at week 2. There was an insignificant increase in both systolic and diastolic blood pressures after four weeks. There was no significant change in either total cholesterol or triglyceride levels during the four weeks.
Plasma 6-keto-PGF1α levels increased significantly from 60.13 ± …

The effect that diet and other modifiers may have upon the immune system of BALB/c mice bearing tumor were studied, mice were injected s.c. with 106 herpes simplex virus Type 2- Adult male BALB/c transformed (H238) cells in the thigh causing a visible fibrosarcoma within 1-2 weeks. Mice were fed either a diet low in protein (milk) and low in fat (Diet 1), or another diet low in protein (wheat) and high in fat (Diet 8). Spleen cells were collected for assays of cytotoxic T-lynphocyte (CTL) and natural killer (NK) cell activity. At 3 weeks post-injection, a decrease in …
Effects Of Two Chelating Drugs On Trace Element Metabolism In The Rat, Thomas J. Solecki
Effects Of Two Chelating Drugs On Trace Element Metabolism In The Rat, Thomas J. Solecki
Theses
Numerous drugs have structures which suggest that they and/or their metabolites are likely to be chelating agents and therefore might affect trace element metabolism. For some drugs, their therapeutic activity or side effects may be due to this chelating potential. Ethambutol, used in the treatment of tuberculosis, is an example. There is also evidence that other drugs, such as alpha-methyldopa, may possess this potential; although its primary therapeutic action occurs via mechanisms other than chelation. The objective of this thesis was to determine the effects of ethambutol and alpha-methyldopa on tissue metal concentrations and balance of four essential trace metals: …
The Effect Of Chronic Low Level Lead Ingestion On Blood Pressure In Young Dogs, Thomas Robert Vetrano
The Effect Of Chronic Low Level Lead Ingestion On Blood Pressure In Young Dogs, Thomas Robert Vetrano
Theses
The relationship between chronic, low level lead exposure and hypertension has been a controversial issue for nearly a century. This study was designed to examine if such exposure is capable of causing hypertension in young dogs. Twelve three-month old female hounds were split into groups of six and paired with their littermate. One group received a dose of 1 mg/kg body weight of lead daily (orally); the controls received equimolar sodium acetate. Blood pressures were determined using an indirect Doppler technique.
Similar blood pressures were recorded for both groups prior to lead dosing. After nine days of lead ingestion, the …
Investigations Into Rates And Mechanisms Of Mercury Depuration In The Killifish, Fundulus Heteroclitus, Joanne A. Korpanty
Investigations Into Rates And Mechanisms Of Mercury Depuration In The Killifish, Fundulus Heteroclitus, Joanne A. Korpanty
Theses
Metallothionein (MT) and glutathione (GSH) have been shown in mammalian research to play a role in the sequestration and depuration of mercury. The sulfhydryl groups on both these peptides have a strong affinity for mercury, MT for Hg2+ and GSH for CH3Hg+. In this study, killifish (Fundulus heteroclitus) were force-fed one piece of squid laced with labelled mercuric nitrate to give a final food concentration of 20 ppm 203Hg2+ and 0.03 -0.05 µg g-1 Hg2+ total dose. Most of the mercury, 84.1 ± 12.1% (mean ± standard deviation), is depurated within the …
Differences In Survivorship, Development Rate And Fertility Between The Long-Winged And Wingless Morphs Of The Waterstrider, Limnoporus Canaliculatus, Anthony J. Zera
Differences In Survivorship, Development Rate And Fertility Between The Long-Winged And Wingless Morphs Of The Waterstrider, Limnoporus Canaliculatus, Anthony J. Zera
Anthony Zera Publications
Species of waterstriders (Gerridae: Hemiptera) exhibit a remarkable diversity in degree of winglessness (Vepsalainen, 1978; Calabrese, 1980; Zera, 1981). Some species consist exclusively of fully-winged individuals, while other species are composed almost exclusively of wingless individuals; many species exhibit the intermediate case of wing polymorphism and consist of various proportions of fully-winged, short-winged and/or wingless morphs. Wing-polymorphic species often exhibit dramatic spatial and/or temporal variation in morph ratios, both among populations of the same species and among species. Because of this diversity, waterstriders, especially wing polymorphic species, are ideal candidates for the study of the evolution of winglessness (or conversely, …
Effects Of Intraperitoneal And Intracerebral Injections Of Triiodothyronine On Temperature Selection In Fish, Dennis A. Grahn
Effects Of Intraperitoneal And Intracerebral Injections Of Triiodothyronine On Temperature Selection In Fish, Dennis A. Grahn
Dissertations and Theses
Goldfish (Carassius auratus) of 15-28g were maintained at 23 C and subsequently were intraperitoneally injected with saline (controls) and varying doses of Triiodothyronine (T3). Following the injection, the fish were placed in a thermal gradient and temperature selection and activity monitored for 30 min. There was no- significant difference between the responses of the experimental fish to the 2 different doses of T3. However, there was a significant difference in response between the experimental and control groups (P < 0.001). The decreased temperature selection occurred early in the test runs, while the increased activity began later. Larger goldfish (175-205g) received 0.5 μl intracerebral injections of 1.5-3.0 ng T3 in the anterior brainstem via an indwelling cannula injection system. These fish responded to the injections by …
Inquiry Into The Causes And Significance Of Cytoplasmic Vacuolation Of Neutrophils In The Peripheral Circulation, Gary Xavier Haight
Inquiry Into The Causes And Significance Of Cytoplasmic Vacuolation Of Neutrophils In The Peripheral Circulation, Gary Xavier Haight
Dissertations and Theses
One-half million cases of septicemia are reported annually with a mortality of around 35%. Diagnosis depends in part on blood cultures which require one to two weeks. It would be advantageous if an early sign of septicemia were available.
Cytoplasmic vacuolation of polymorphonuclear neutropnils is occasionally seen in the peripheral blood smears of patients who have infections. The object of this work was to determine the cause and significance of cytoplasmic vacuolation with the goal of using the occurrence of vacuolation as an early indicator of infection.

Yet, one in this field should know something about disciplines ranging from physiology, or in the case of the subject of this lecture, even photochemistry, to the study of entire ecosystems.
A Bacteriological And Chemical Analysis Of Nonpoint Source Pollution In A Karst Aquifer Bowling Green, Kentucky, Wayne Green
A Bacteriological And Chemical Analysis Of Nonpoint Source Pollution In A Karst Aquifer Bowling Green, Kentucky, Wayne Green
Masters Theses & Specialist Projects
Monthly water samples collected from four sites in the Lost River Groundwater Basin, a shallow karst aquifer in the Bowling Green-Warren County area of Kentucky, represented samples from sites receiving conduit and diffuse flow. All sites were severely contaminated with bacteria, and on some occasions the surface water criteria for some heavy metals were exceeded.
Of the total 334 bacterial colonies identified 92.1% were verified as Escherichia coli by the API20E system. Acinetobacter calcoaceticus var. anitratum accounted for 2.10% of colonies; Citrobacter freundii for 0.30% Klebsiella pneumoniae for 0.90%; Klebsiella oxytoca, 0.90%; Citrobacter amalonaticus 0.30%; Enterobacter cloacae, 1.20%; …
Phenotypic Differences In Populations Of Euonymus Americanus L. From The Central United States & Autecological Studies Of This Species In A Deciduous Forest Of Kentucky, Paul Bayer
Masters Theses & Specialist Projects
The concentrations of sodium and potassium in the leaves of Euonymus americanus collected from a relict hardwood forest during a four month period showed a possible winter conditioning pattern. Seeds collected from this same relict stand would not germinate, even though they were subjected to a wide variety of germination experiments. Phenotypic differentiation in fully developed leaves was not found; however, differences related to the length of the growing season were noted. Autecological studies of Euonymus americanus should be continued to investigate the role of this plant in relict hardwood stands.

Relationships Among Measures Of Testicular Development And Endocrine Function In Boars, A. P. Schinckel, R. K. Johnson, R. J. Kittock
Department of Animal Science: Faculty Publications
Nine blood samples were taken at 30-min intervals from 36 Landrace x Large White boars at each of eight ages (42, 56, 70, 84, 98, 112, 126 and 140 d). Serum concentrations of luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone (T) and estradiol- 17β (E-2) were quantified by radioimmunoassay procedures. The maximum concentration of LH and the age at maximum concentration were predicted for each boar. Variability of LH samples was described for each boar by the pooled within age variance among LH samples and by the number of LH peaks. Measurements of testicular development taken at 140 …
