Sister Chromatid Exchanges In A Male With A Y/Y Translocation, Merlin G. Butler

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Sister chromatid exhanges (SCE) are considered indicators of genetic damage and early chromosome changes. The SCE frequency from an infertile 27-year-old, white male with tall stature and a non-dicentric Y/Y translocation consisting of one short arm and two long arms of the Y chromosome was determined. The SCE frequency was 7.9 ± SD 1.4 while to SCE frequency from ten control subjects was 8.4 ± SD 0.51. A two-tailed t-test was applied to the SCE data and no significant difference was found between the individual with the Y/Y translocation and control subjects. Apparently, this altered chromosomes does not interfere …

Further Observations On Polymegaly In Species Of The Drosophila Affinis Subgroup, Ho-Chi Chang, Dwight D. Miller

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Polymegaly, or the production of two or more size class of sperms by the same male, has been known in Drosophila for more than a decade. More recently polymegaly (dimegaly, or two size classes) was found in the Drosophila affinis subgroup. Additional observations on polymegaly in six D. affinis subgroup species: D. affinis, D. algonquin, D. athabasca, D. azteca, D. narragansett, and D. tolteca are reported here. The two kinds of sperms differ strikingly in the nature of the head, which is elongate (threadlike) in "long" sperms, short and dense in "short" sperms. Ultraviolet fluorescence following treatment with 4', 6-diamidino-2-phenylindole …

Comparative Water Relations And Photosynthesis Of Mycorrhizal And Non-Mycorrhizal Bouteloua Gracilis H.B.K. Lag Ex Steud., Michael F. Allen, William K. Smith, Thomas S. Moore Jr., Martha Christensen

Department of Plant Pathology: Faculty Publications

The rangeland grass, Bouteloua gracilis was inoculated with its mycorrhizal symbiont, Glomus fasciculatus, to determine the influence of vesicular-arhuscular mycorrhizae on water status, stomatal behaviour and photosynthesis as well as gross plant morphology, biomass and phosphorus content. Mycorrhizal infection increased transpiration rates by over 100% with 50 to 70% lower leaf resistances to water vapour diffusion. Leaf xylem pressure was not different between mycorrhizal and non-mycorrhizal plants indicating that whole-plant resistance to water transport was reduced by more than 50%. Photosynthetic rates under saturating light conditions increased 68% with infection as a consequence of a 33% reduction in stomatal …

Allergenicity Of Various Peanut Products As Determined By Rast Inhibition, Julie A. Nordlee, Steve L. Taylor, R. T. Jones, John W. Yunginger

Department of Food Science and Technology: Faculty Publications

Extracts of 19 different peanut products and peanut oil were tested for their allergenicity by the radioallergosorbent test inhibition assay using a crude peanut extract from raw peanuts as the standard for comparison. Seventeen of the extracts were able to competitively inhibit the binding of serum IgE from peanut-sensitive patients with the solid-phase raw peanut extract. Peanut oil and the extract from hydrolyzed peanut protein did not inhibit binding, which suggests that these products are not allergenic. The peanut hull flour extract showed a slight ability to inhibit binding, suggesting that this product contains minor amounts of the peanut allergen.

Factors Affecting Insecticide-Induced Resurgence Of The Brown Planthopper, Nilaparvata Lugens On Rice, S. Chelliah, E. A. Heinrichs

Department of Entomology: Faculty Publications

Resurgence of the brown planthopper, Nilaparvata lugens (Stål) on rice was induced by applications of decamethrin, methyl parathion, and diazinon. Differential mortality of predators and hoppers did not appear to be the primary factor for resurgence. Hoppers appeared to be attracted to methyl parathion and decamethrin treated plants because of plant growth. Improved plant growth, however, did not compensate for the increased feeding of the insecticide-treated hopper population, and plants treated with resurgence-causing insecticides succumbed to feeding injury earlier than untreated plants. Population increases were due in part to stimulation of reproduction of the hopper, either by contact action of …

Effects Of Supplementary Amino Acids In An All-Corn Diet On The Growth And Metabolic Performance Of Young Rats And Pigs, Dale Alan Grosbach

Open Access Master's Theses (through 2010)

While there is presently an agreement on the status of lysine and tryptophan being closely first and second, or co-limiting, little beyond this is known. Which amino acids are the next limiting, and if they would give an important performance boost is unknown.

The stage of the pig’s growth at which these factors are examined may also be important. Much of the work has been done with larger growing or finishing of pigs. It may be more advantageous to work with pigs that weigh from 10 to 35 kg compared to the 40 to 110 kg animal. It is at …

Incorporation Of Specific Fatty Acid Precursors During Spore Germination And Outgrowth In Bacillus Thuringiensis, Kenneth W. Nickerson, Lee A. Bulla Jr.

Papers in Microbiology

The selective incorporation of precursors specific for individual fatty acids in germinating and outgrowing spores of Bacillus thuringiensis is described. The specific precursors utilized were [¹⁴C]butyrate, -isobutyrate, -valerate, and -isovalerate, which were incorporated into even-numbered normal-chain isomers, even-numbered iso-isomers, odd-numbered normal-chain acids, and odd-numbered isohomologs, respectively. This preferential incorporation by B. thuringiensis allows the terminal carbons of specific normal and branched-chain fatty acids, contained within the cytoplasmic membrane, to be labeled with ¹⁴C and, potentially, ¹³C.

Biology And Pathogenesis Of The Coccidium Eimeria Funduli Infecting Killifishes, Mobashir A. Solangi, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Epizootics of Eimeria funduli involved estuarine killifishes (Fundulus grandis, F. pulvereus, F. similis, and F. heteroclitus) in Mississippi, Alabama, and Virginia. All of more than 500 specimens examined of F. grandis from Mississippi during 1977 through 1979 had infections, regardless of age, sex, or season collected. Oocysts occurred primarily in the liver and pancreas, replacing up to 85% of both those organs. Infrequent sites of infection were fatty tissue of the body cavity, ovary, intestine, and caudal peduncle. Living fish did not discharge oocysts. Eimeria funduli is the first known eimerian to require a second host. To …

Relationship Between Relative Brain Size And Climbing Ability In Peromyscus, Cliff A. Lemen

School of Natural Resources: Faculty Publications

Eisenberg and Wilson (Evolution, 32:740-751, 1978) have documented an interesting relationship between the relative brain size of bats and the complexity of the habitat in which they forage. They found that bats that fly and forage through foliage have larger brains relative to their body size than those that forage in open air. Their explanation was that bats in the complex habitat must process more complex sonic information to navigate through the foliage. In order to do this a larger brain is required.

The Peromyscus of North America may offer a similar paradigm as far as habitat complexity …

Metric Units Of Measure - Part Ii Fluid Volume, Mass, Temperature, Pressure, Power And Energy, Elbert C. Dickey, Allen R. Rider, Gerald Bodman

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The metric and U.S. customary systems of measure differ in terminology for fluid volume, mass, temperature, pressure, power and energy. The relationships between the metric and U.S. customary system for these units are described and illustrated graphically in the following text.

Fluid Volume- Fluid volumes are usually measured in milliliters or liters. Small quantities of liquid products are expressed as milliliters or as cubic centimeters. Gasoline, milk and other similar sized volumes are measured in liters.

Mass - Mass is the amount of matter in an object and is normally referred to as weight. The common metric units of …

Red Kangaroo Management In Western Australia, C.D. Gooding

Vertebrate Pest Conference Proceedings: 9th (1980)

The Red Kangaroo is the dominant native grazing herbivore over much of the arid rangeland area of Western Australia, where the species exists side by side with introduced livestock. The numbers are such that Red Kangaroos can be utilized as the basis for a commercial harvesting industry provided the population is managed on a sustained yield basis. The WA Management Programme is designed to take account of the need for conservation of the species and for protection of the livestock industry and the rangelands on which both kangaroos and the livestock industry depend.

Factors Responsible For The Successful Establishment Of Exotic Avian Species In Southeastern Florida, Alison C. Rand

Vertebrate Pest Conference Proceedings: 9th (1980)

Presently southeastern Florida has at least 24 established exotic avian species from both New and Old World families. This much man-modified region of Florida is characterized by the Atlantic Coastal Ridge in Palm Beach, Broward and Dade Counties and the Florida Keys of Monroe County. Because of the draining of the Everglades to the west, the filling of the mangroves on the seaward side, and the accompanying urban-suburban sprawl, many exotic plant species have invaded the Ridge thus preparing the environment for introduced birds. The Red-whiskered Bulbul, Pycnonotus jocosus, illustrates this point. Most exotic avian species have appeared and colonized …

An Assessment Dependent Upon Technology, F. Gregory Hayden

College of Business: Faculty Publications

"Technology and Economic Dependency: An Institutional Assessment,"' by Thomas De Gregori, deserves serious consideration because it reaches to the heart of a conflict in holistic economic systems analysis and planning. The major issue in the article revolves around divergent views regarding technology. One is that technology should dominate society by being made the primary determinant of policy evaluation criteria. Another view is that technology should be treated as a system entity, albeit a powerful one, which must be evaluated along with others. De Gregori's conclusions are based on the first view.

This comment will consider five aspects of De Gregori's …

Seasonal Forage Availability In Relation To Energy Requirements Of Pine Voles In Two Orchard Types, R. L. Lochmiller, J. B. Whelan, R. L. Kirkpatrick

Eastern Pine and Meadow Vole Symposia

Results from previous work on pine vole populations and habitat interactions (Cengel et a1. 1978; Noffsinger 1976) suggested that pine vole populations were quite sensitive to seasonal changes in the quantity, species composition, and nutritive value of available forage. This conclusion was based on decreases in both reproductive performance and physical condition of pine voles collected from abandoned orchards in the fall as compared to voles taken from maintained orchards during the same season. Utilizing information from these investigations, a "follow-up" study was designed to investigate food availability and nutrient composition, food consumption, food digestibility, and energy requirements of pine …

Management Model For Pine Voles: Preliminary Report, John F. Coyle, Alan R. Tipton

Eastern Pine and Meadow Vole Symposia

The use of computer models in scientific research has grown by leaps and bounds in the past decade. One of the primary reasons for this growth is the increased realization that computers and more specifically computer models, can be useful tools in synthe¬sizing large amounts of information and providing insight into problem areas of research and management.

Numerous books and papers have been written on the justification for modeling, the philosophy of modeling, and model development and utilization. Recent reviews of small mammal population models are given by Conley and Nichols (1978) and Stenseth (1977). This paper will not address …
