Research Vistas In The Multiple Endocrine Neoplasia Syndromes, John J. Mulvihill

Henry Ford Hospital Medical Journal

Progress in understanding the single gene, cytogenetic, and multifactorial traits that predispose to human cancer suggests possible new directions for research in the multiple endocrine neoplasia (MEN) syndromes. Among the other 200 or so monogenic disorders associated with human neoplasia, advances have come from further delineation of syndromes by various clinical specialists, the recognition of subtypes of syndromes previously thought to be homogeneous, the search for in vitro manifestations of the mutant gene in fibroblasts, and the establishment of cell, tissue and patient registries and of voluntary lay organizations to serve as advocates for the disease. With regard to cytogenetics, …

Temperature-Dependent Model For Development Of Nondiapausing Sorghum Midges (Diptera: Cecidomyiidae), Frederick P. Baxendale, G. L. Teetes, P. J. H. Sharpe, H. Wu

Department of Entomology: Faculty Publications

Constant-temperature development data were used to construct a temperature- dependent, two-component model for the development of nondiapausing sorghum midges, Contarinia sorghicola (Coquillett), from egg to adult emergence. When constant temperatures were between 20 and 36°C, nondiapausing midges completed development and emerged as adults. Development times decreased as temperature increased. Above 34°C, however, development times increased and numbers of emerged adults declined. A coupled poikilotherm rate equation and cumulative Weibull distribution provided accurate descriptions of the developmental data. Model simulations compared favorably with observed emergence of adult midges from johnsongrass and sorghum in the field throughout the season.

Resource Partitioning In Seven Species Of Sympatric Intertidal Chitons (Mollusca: Polyplacophora), Richard D. Piercy

Loma Linda University Electronic Theses, Dissertations & Projects

Space (intertidal height and location/exposure on the rock surface), and food {gut contents) were partitioned among 7 species of sympatric intertidal chitons: Mopaliidae - Mopalia hindsii, M. ciliata, ~· lignosa, M. muscosa, and Katharina tunicata; and Ischnochitonidae - Tonicella lineata and Cyanoplax dentiens. Species distribution relative to intertidal height (-0.3m to +0.9m) showed significant differences. M. hindsii, ~· ciliata, M. lignosa, and T. lineata preferred slopes or undersides of rocks while ~· muscosa, K. tunicata, and c. dentiens occurred on the top horizontal surfaces or in more exposed habitats. Chitons differed significantly in their associations with Lithothamnion, macrophytic algae, Ulva, …

Soil Physical Characteristics Of Reduced Tillage In A Wheat-Fallow System, L. N. Mielke, Wallace Wilhelm, K. A. Richards, C.R. Fenster

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Soil physical characteristics of reduced tillage for fallow-wheat (Triticum aestivum L.) were compared for two soils in western Nebraska. The soil physical environment influences the amount of water that enters soil, the availability of water for plants, and the microenvironment important to soil biological processes. Fallow tillage (plow, subtill, no till) did not affect bulk density in Alliance silt loam (fine silty, mixed mesic, Aridic Argiustolls). For Duroc loam (fine silty, mixed mesic Pachic Haplustolls), in which native sod was compared to the above three wheat-fallow tillage methods, numerous effects on soil physical properties were found. Reduced tillage reduced …

Nesting Common Moorhen In Lancaster County, William C. Garthright

Nebraska Bird Review

On 6 July 1984, at 6 PM CDT, I saw a Common Moorhen at the Capitol Beach marsh, in Lincoln. It was about 10 yards to the north when I first saw it, and I could see the red facial shield and red bill with yellow tip, the yellow legs, a thin white horizontal line along the side, and prominent white patches along either side of dark undertail coverts. It acted mildly agitated, and swam away from me but stayed in the vicinity.

At 7 the next morning I waded into the pond at that spot. This time I saw …

1984 Fall Field Day

Nebraska Bird Review

The 1984 Fall Field Day was held (officially) from noon to noon, 6/7 October, at the4-H Camp at Halsey National Forest. The weather was not the best—light rain early Saturday morning, only a couple of short showers in the afternoon, and no rain Sunday, both days dull and gray. But the attendance was good—87 were officially registered—but the added manpower could not make up for the lateness in the season and the poor weather—the tally on or near the Forest was only 81. In addition, 4 species (marked N) not recorded in the Forest were seen by a party that …

An Exceptional "Fall" Migration Of Shorebirds Along The Big Bend Reach Of The Platte River, Gary R. Lingle, Thomas E. Labedz

Nebraska Bird Review

The Big Bend reach of the Platte River extends about 80 miles from Overton to Chapman, Nebraska. This area is characterized by braided channels with numerous riverine islands bordered by cottonwoods (Populus deltoides) and willows (Salix spp.) along the high banks. Habitat between the high banks consists of open water, barren sandbars and mudflats, herbaceous islands, shrub islands, and floodplain forest.

Prolonged summer flows during 1983 were among the highest recorded this century; in excess of 20,000 cfs (cubic feet per second). Spring 1984 also consisted of high flows resulting in much scouring and shifting of …

Surface Roughness Contribution To The Auger Electron Emission, D. Wehbi, C. Roques-Carmes

Scanning Electron Microscopy

Scanning Auger Microscopy (SAM) experiments have shown that z height and θ slope relative to the analysed spot are parameters that contribute to the measured Auger intensity I(z, θ). For greater analysed areas specific to Auger Electron Spectroscopy (AES), the knowledge of height and slope statistical distributions P(z) and P(θ) is required. These functions have been determined by means of profilometric data. The spatial resolution of the used tactile profilometer is similar to that which characterizes AES. A mathematical relationship I { P(z), P(θ) } has been set up for Si samples whose roughness is well defined. On the other …

Vegetation Patterns In Relation To Topography And Edaphic Variation Nebraska Sandhills Prairie, P. W. Barnes, A. T. Harrison, S. P. Heinisch

School of Biological Sciences: Faculty Publications

Detailed studies on soil texture and moisture retention indicate a close association between edaphic features and the distribution and composition of plant communities along topographic gradients at Arapaho Prairie, a typical, semi-arid Nebraska Sandhills prairie. The vegetation characteristics of three major habitat types (ridge, slope, and valley) and several minor subtypes (swale, stable ridge, and eroding ridge) are recognized and quantitatively described. Texture analysis indicates that the soils of dune slopes and ridges are largely azonal and are very coarse with substantially lower fine fractions (silt-clay ~ 13-15%) than soils of the more lowland swale and valley sites where surfact …

The Role Of The Salivary Glands In Uptake Of Fluoride In Teeth And Bone, Robin E. Vance

Loma Linda University Electronic Theses, Dissertations & Projects

The cariostatic capability of fluoride is generally recognized, in addition, it may also have a beneficial effect on bone. Fluoride is thought to exercise its cariostasis through a local effect on teeth, however, the possibility exists that fluoride exerts its action through a systemic mechanism. Fluoride uptake by rat teeth and its effectiveness as a cariostatic substance was studied in parotidectomized, submaxillariectomized, and totally sialoadenectomized animals (both parotid and submaxillary glands removed). The uptake of fluoride in bone was also quantitated for comparison purposes.

Rats were injected daily with 15 micromoles of fluoride dissolved in 0.1 ml saline. The rats …

A Quantitative Study Of The Distinctive Proteins Of The Eosinophil: A Comparison Of Normals And Eosinophilic Patients, James M. Olson

Honors Theses

Eosinophils have long been associated with parasitic and allergic diseases. Methods of procurement and purification of eosinophils in the last ten years have allowed intensive investigation into their components, properties, functions, and mechanisms (Gleich et al, 1982). The goals of this project are to separate eosinophils in blood samples taken from patients with eosinophilia and from normals based on density over distontinuous Metrizamide gradients; to determine quantitatively the levels of the three distinctive proteins of the eosinophil, specifically MBP, EDN, and ECP; and to compare the levels of these proteins found in eosinophils of patients with eosinophilia to the amounts …

Autoradiography Of Photomembrane In Hemigrapsus Nudus, Carol Fulenwider

Loma Linda University Electronic Theses, Dissertations & Projects

Protein synthesis was studied in the visual cells of Hemigrapsus nudus by light microscope autoradiography. Two hours before sunset, crabs were injected with a single dose of tritiated leucine and sacrificed at time intervals coincident with dynamic retinal changes observed in electron microscope (EM) studies of related Arthropods (Blest, 1978 and Stowe, 1980).

Two separate experiments were performed to examine time periods in the renewal process. Some periods in each experiment were overlapped to develop more accurate decay curves. Experiment I followed time regimes of 0.5, 1.5, 2.5, 3.0, 3.0, 5.0, and 6.0 hours after sunset. Autoradiographs of retinula cells …

The Role Of Vasopressin In The Fetal Renal Response To Hypertonicity, Lori L. Woods

Loma Linda University Electronic Theses, Dissertations & Projects

In order to study the effects of hyperosmolality on fetal renal function and to gain insight into the role of AVP in the fetal urine concentrating mechanism, two types of studies were performed. In whole animal studies 9% NaCl was injected intravenously into 8 chronically catheterized pregnant ewes of 130-135 days gestation and their fetuses, followed by a continuous infusion of 9% NaCl into the ewes. Fetal and maternal plasma osmolalities rose initially by 5% and remained elevated for the next four hours. Fetal arterial and venous pressures increased transiently. Fetal urine flow increased transiently by 73%, remained elevated for …

Effects Of Space Shuttle Exhaust Plumes On Gills Of Some Estuarine Fishes: A Light And Electron Microscopic Study, William E. Hawkins, Robin M. Overstreet, Mark J. Provancha

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

The first few launches of the space shuttle resulted in fish kills in a lagoon near the launch site. To study this phenomenon further, sheepshead minnow (Cyprinodon variegatus), sailfin molly (Poecilia latipinna), and mosquitofish (Gambusia affinis) were exposed to the exhaust plume in buckets placed near the launch site. An open bucket provided a full exposure, a partly closed one provided an intermediate exposure, and a closed one was the control. Three h after launch, the pH of the water from the full exposure had decreased from about 7 to about 3, Al and …

Methylphenidate Effects On The Learning And Performance Of Four Hyper Active Children, Paul James Yoder

Dissertations

The effects of methylphenidate hydrochloride (Ritalin) on the learning and performance of four hyperactive children were evaluated using a repeated acquisition procedure with both learning and performance components. Three dosages of methylphenidate plus a placebo were evaluated under double-blind experimental conditions. Dosages treated included each subject's therapeutic dosage, a dosage 5 milligrams higher, and a dosage 5 milligrams lower. Methylphenidate produced no effect on either the number of errors per session or on the rate of responding across the range of dosages tested suggesting that the medication neither facilitated nor impaired learning or performance. Data were also collected on social …

Habitat Use By Black Bears In Relation To Forest Management In Pisgah National Forest, North Carolina, Allan Joseph Brody

Masters Theses

A total of 1310 locations was obtained on 18 radio collared black bears (Ursus americanus) in Pisgah National Forrest, North Carolina, during 1982 and 1983. Male home ranges averaged 3205 ha in summer and 6931 ha in fall. Female home ranges averaged 872 hectares in summer and 1712 hectares in fall. Nine of the collared animals were killed by hunters during the study, 4 of these illegally.

Bear habitat use was analyzed in relation to timber management parameters available in the U. S. Forrest Service "Continuous Inventory of Stand Condition" and other parameters derived from stand and topographic maps. Chi-square …

History And Distribution Of Brook Trout In The Appalachian Region Of Tennessee, Rick Dwain Bivens

Masters Theses

Brook trout (Salevlinus fontinalis) populations have been declining in the southern Appalachians and especially in Tennessee since 1900. To assess the loss of range of this southern trout, various agencies have inventoried most of the major trout streams in Tennessee over the past 10 years. To date, however, these surveys have remained disjunct and in some cases overlapping.

Survey reports and field data of brook trout inventories made from 1974 to 1984 were examined to determine the current distribution in Tennessee. Brook trout currently inhabit 275.6 kilometers in 135 streams found in eight east Tennessee counties. Brook trout …

Regurgitation By The Face Fly, Musca Autumnalis Degeer, Russell E. Coleman

Masters Theses

Face flies normally began regurgitating within 10 minutes after feeding, and continued for periods of up to 240 minutes. Almost 100 percent of flies fed a concentrated (4.8%) solution of trypticase-soy broth were observed regurgitating. The deposition of droplets onto a substrate was almost never observed, indicating that the regurgitation is not analogous to vomiting. The droplet exuded contained from five to ten percent of the food consumed, with the crop the source of the fluid. The crop is also the most likely destination of the regurgitated materiel. The purpose of this phenomenon is still not clear. However, the fluid …

Impact Of Screening On Prognosis In The Multiple Endocrine Neoplasia Type 2 Syndromes: Natural History And Treatment Results In 105 Patients, Margareta Telenius-Berg, Bertel Berg, Bertil Hamberger, Sten Tibblin, Lars-Erik Tisell, Lars Ysander, Gunnar Welander

Henry Ford Hospital Medical Journal

We evaluated the effects of screening for multiple endocrine neoplasia type 2A (MEN-2A) in 12 families. Genealogical studies going back to 1730 show a common ancestry for seven Swedish families and one American family. The total number of patients included 105 individuals, 68 of whom were diagnosed by our screening program. Our screening methods for medullary carcinoma of the thyroid (MTC) had an optimal sensitivity and specificity. The frequency of gene carriers detected in MEN-2A families was 55%. Screening will lead to early diagnosis and early therapy, which in turn, will significantly decrease morbidity, incidence of surgical complications, and mortality …

Screening For Hereditary Medullary Cancer In Denmark, Kristian Emmertsen

Henry Ford Hospital Medical Journal

Screening of first-degree relatives of patients with medullary thyroid cancer (MTC) gave normal values of pentagastrin-stimulated serum calcitonin and 24-hour urinary catecholamine levels in the relatives of 18 of 22 patients. This result is considered to be valid evidence for sporadic MTC. Absence of C-cell hyperplasia maybe another indication of sporadic MTC. Four hereditary MTCs were represented by one fully expressed MEN-2B patient without affected relatives, one fully expressed MEN-2A case in one family, and two first cousins with MTC as the only MEN-2A lesion in another family. Fourteen relatives of the MEN-2A patients had elevated serum calcitonin levels, and …
