Early Vagotomies At Henry Ford Hospital: An Historical Vignette And A Follow-Up, James C. Gruenberg, Conrad R. Lam

Henry Ford Hospital Medical Journal

Over a one-year period beginning in April, 1946, nine transthoracic vagotomies were done at the Henry Ford Hospital. Three of the patients had had a partial gastrectomy previously and the operation was done for recurrent bleeding from marginal ulcers. Thirty years later, an attempt was made to ascertain the present condition of these patients. Long term follow-ups were possible on six patients and follow-ups of one, six and 14 years on the others. All nine patients had immediate relief of ulcer pain and cessation of bleeding if present. No subsequent drainage operation was required for the six patients with primary …

Growing Degree Days Predictions For Corn And Sorghum Development And Some Applications To Crop Production In Nebraska, R. E. Neild, M. W. Seeley

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The concept of growing degree days (GDD) originated with observations by Reamur (1735) that plant development is more closely related to the temperature accumulated to a given stage than with time alone. It was not until nearly 200 years later, however, that Merriam (1894), Livingston (1916) and Klages (1942) began to use temperature accumulations in plant distribution studies and in crop geography. In the early 1950's, a system involving growing degree days became widely used in the canning industry to schedule plantings and thus control time of harvest of rapidly maturing vegetables. This system provided a more precise control of …

Apical Closure Induction Using Bone Growth Factors And Mineral Trioxide Aggregate, Kenneth W. Tittle

Loma Linda University Electronic Theses, Dissertations & Projects

This study compared the ability of three different bone growth factor combinations with that of Ca(OH)₂ to stimulate apical closure as well as the effectiveness of Mineral Trioxide Aggregate (MTA) as an apical barrier. Fifty-six roots of second and fourth mandibular premolars of seven six- month old beagle dogs were used. Periradicular lesions were created over a four week period. The canals were cleaned and shaped and filled with Ca(OH)₂ for one week. They were then irrigated and received one of seven different treatments in a balanced design. Growth factors were placed in a carboxymethylcellulose carrier and delivered …

Fine-Structure Map Of The Histidine Transport Genes In Salmonella Typhimurium, Giovanna Ferro-Luzzi Ames, K. Dale Noel, H. Taber, E. Negri Spudich, Kishiko Nikaido, J. Afong, F. Ardeshir

Biological Sciences Faculty Research and Publications

Afine-structure genetic map of the histidine transport region of the Salmonella typhimurium chromosome was constructed. Twenty-five deletion mutants were isolated and used for dividing the hisJ and hisP genes into 8 and 13 regions respectively. A total of 308 mutations, spontaneous and mutagen induced, have been placed in these regions by deletion mapping. The histidine transport operon is presumed to be constituted of genes dhuA, hisJ, and hisP, and the regulation of the hosP and hisJ genes by dhuA is discussed. The orientation of this operon relative to purF has been established by three-point crosses as being: purF …

The Vegetation Of South Padre Island, Texas In Relation To Topography, Frank W. Judd, Robert I. Lonard, Sammie L. Sides

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Vegetation patterns were studied in relation to topography to ascertain the degree of phytosociological change and to provide an inventory of the vegetation of South Padre Island. Six major terrestrial topographic zones were recognized: (1) Foreshore, (2) Backshore, (3) Primary dunes, (4) Secondary dunes and vegetated flats, (5) Tidal flats, and (6) Washovers. The flora includes at least 204 species of angiosperms representing 47 families. Five families, Compositae (26), Cyperaceae (10), Gramineae (46), Leguminosae (24), and Scrophulariaceae (8), account for 55.9% of the species diversity. The vegetation occurs in distinct zones that correspond closely to topographic facets. Comparison of three …

The Fatty Acid Composition Of Some North American Dwarf Mistletoe, Hwa Chen

Dissertations and Theses

Fatty acid composition of five dwarf mistletoe species was analysed by Gas Liquid Chromatography. Because of the limitations of available equipment, only aerial shoots were analysed. Palmitic, oleic, linoleic and arachidic acids were the major components of total lipids. The sum of these acids accounted for 85-95 percent of total lipids present in the tissue. There was no apparent difference between species. The ratio of saturated acids to unsaturated acids in summer collections was higher than that of fall collections. Temperature may play an important role in controlling of these ratios. Lipid content varied from 3.25% to 8.5% on a …

A Study Of Home Range In Two Neotoma Fuscipes Colonies In Klamath County, Oregon, Brent D. Frazier

Dissertations and Theses

Home ranges of dusky-footed wood rats (Neotoma fuscipes) were determined by the exclusive boundary strip method in two colonies 630 m apart in Klamath County, Oregon. The mean home range area was 1800 - 1900 m² . Densities or trees and shrubs were determined on selected home ranges and densities of wood rat houses and nests were determined on all home ranges. No significant correlation was found between home range areas and densities of various trees and shrubs, home range areas and densities of woodrat houses and nests, or home range areas and weights of woodrats in …

Intermolecular Potential Surfaces From Electron Gas Methods. Ii. Angle And Distance Dependence Of The A’ And A” Ar–No(X^2ii) Interactions, Glen C. Nielson, Gregory A. Parker, Russell T. Pack

Faculty Publications

Angle dependent intermolecular potential energy surfaces for the two states (2A’ and 2A”) that arise from the interaction of ground (X^2II) state NO with Ar are calculated using the electron gas model to obtain the short range interactions. The average and difference of the two interaction energies are fit to analytic forms convenient for use in scattering calculations and joined smoothly onto the long range van der Waals potential previously determined. The results, which appear to be of useful accuracy, and the applicability of the electron gas model to such open shell–closed shell interactions are discussed.

Optimal Prey Selection In The Great Tit (Parus Major), John Krebs, Jonathan Erichsen, Michael Webber, Eric Charnov

Biology Faculty & Staff Publications

We tested the predictions of an optimal foraging model using five captive great tits as predators. The birds were presented with two prey types, profitable and unprofitable, on a moving belt. Both prey types were made out of mealworms. When the encounter rate with both prey types was low, the birds were non-selective, but at a higher encounter rate with profitable prey, the birds selectively ignored the less profitable type and did so irrespective of the encounter rate with them. These results are as predicted by the model, but the birds did not as predicted change from no selection in …

Life History And Host Specificity Of Mediorhynchus Centurorum Nickol 1969 (Acanthocephala: Gigantorhynchidae), Brent B. Nickol

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Examination of 1905 arthropods from a swamp and surrounding pasture in southern Louisiana revealed larval specimens of Mediorhynchus centurorum in 8 of 228 woodroaches, Parcoblatta pensylvanica, but in no other species. The life cycle was confirmed by feeding eggs of M. centurorum to laboratory-reared woodroaches. Cystacanths later recovered from the woodroaches developed into mature worms when pipetted into esophaguses of red-bellied woodpeckers, Centurus carolinus; redheaded woodpeckers, Melanerpes erythrocephalus; yellow-shafted flickers, Colaptes auratus; and a hairy woodpecker, Dendrocopos villosus. Infection was achieved in all woodpeckers fed cystacanths at least 47 days old and the mean prepatent …

Aploparaksis Borealis Sp. N. (Cestoda: Hymenolepididae) From Passeriform And Charadriiform Birds In Chukotka And Alaska, S. K. Bondarenko, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Aploparaksis borealis sp. n. (Cestoda: Hymenolepididae), from the long-tailed jaeger, Stercorarius longicaudus Vieillot, on the Seward Peninsula, Alaska, and from the red-throated pipit, Anthus cervinus (Pallas), and the Lapland longspur, Calcarius lapponicus (Linnaeus), in Chukotka, northeastern Siberia, is described. This cestode is distinguished by the structure of the cirrus and other morphologic characters from other species of Aploparaksis Clerc 1903 in which there are 10 rostellar hooks and the vitelline gland is aporal to the ovary. A. borealis is the first species of Aploparaksis to be reported from birds representing two orders (Passeriformes and Charadriiformes).

Distribution, Habitat Notes, And The Status Of The Ironcolor Shiner, Notropis Chalybaeus Cope, In Arkansas, Henry W. Robison

Journal of the Arkansas Academy of Science

Field work throughout Arkansas since 1971 and a search of museum records have yielded 35 collections of the iron color shiner, Notropis chalybaeus Cope (Cyprinidae), not previously documented in Arkansas. From these data the iron color shiner is considered to be confined to the Coastal Plain physiographic province of Arkansas below the Fall Line, becoming most abundant in the Ouachita and Red River drainages of southern Arkansas. Notes on habitat preference, species associates, and current status of N. chalybaeus within Arkansas are presented.

Algal Assemblage Distribution As Related To Seasonal Fluctuations Of Selected Metal Concentrations, Ramona G. Rice, Richard L. Meyer

Journal of the Arkansas Academy of Science

Seasonal variations of phytoplankton assemblages have been observed in a mildly eutrophic lake in northwestern Arkansas for six years. The data indicated that certain metal concentrations also varied seasonally. Sodium, potassium, calcium and magnesium ion concentrations, and phytoplankton composition and abundances were examined spatially and temporally. Four major algal blooms characterized the lake: a spring, a summer and an autumnal cyanophycean assemblage and a winter diatom-chrysophyte dominated population. Each metal concentration was inversely proportional to the abundance of the cyanophytes. The presence of the winter assemblage was accompanied by decreases in sodium, calcium and magnesium and increased levels of potassium. …

Evaluation Of Plantings For Wildlife On A Power Line Right Of Way In Southern Arkansas, Robert A. Pierce, Robert T. Kirkwood

Journal of the Arkansas Academy of Science

The combination of types of land preparation and species of plants seeded along a power line right-of-way was evaluated in terms of the effects upon wildlife. Relative population densities of plants, birds, and mammals were determined for each of the areas under study. A study of the reduction in maintenance costs in relation to the initial investment for preparation and seeding of the land was made

Time Course Of Pr Of Uv-Induced Chromosomal Aberrations And Lethal Damage In G1 Xenopus Cells, Jan Payne, H. Gaston Griggs

Journal of the Arkansas Academy of Science

Synchronous cultures of early G1 cells were exposed to UV and their ability to photoreactivate lethal and aberrational damage was determined as a function of time following UV exposure. Lesions leading to cell death were converted to a non-photoreactivable state before cells entered S phase, while lesions leading to chromosomal aberrations were converted to a non-photoreactivable state as the cells entered S phase. These results indicate that the intracellular mechanism which expresses photoreactivable UV-induced lesions in G1 cells as cell death is not identical to the mechanism which expresses such lesions as chromosomal aberrations, and the two mechanisms operate primarily …

Immunization Of Rats Against Mesocestoides Corti (Cestoda) By Subcutaneous Vaccination Of Living Tetrathyridia And By Passive Transfer With Serum, Jerry Y. Niederkorn

Journal of the Arkansas Academy of Science

Laboratory rats were subcutaneously vaccinated with 100 live tetrathyridia of Mesocestoides corti (Cestoda) and subsequently intraperitoneally challenged with 50 tetrathyridia. Necropsy 30 days postinfection revealed that vaccinated rats harbored 97.4% fewer worms compared to control rats. In a second experiment, passive transfer of immunity was accomplished by immune serum from subcutaneously vaccinated rats. Rats receiving immune serum harbored 33.4% lighter worm burdens compared to normal serum recipients.

Mosquitofish, Gambusia Affinis (Baird And Girard) Production In Extensive Polyculture System, Scott H. Newton, Andrew J. Merkowsky, Ambus J. Handcock, Max V. Miesch

Journal of the Arkansas Academy of Science

During 1976, mosquitofish, Gambusia affinis Baird and Girard, were reared in combination with food and game fishes in 0.1 ha culture ponds at the University of Arkansas at Pine Bluff fisheries research facility. Mosquitofish production was 218 kg/ha, with 1683 fish per kilogram, in ponds that were also stocked with channel catfish, Ictalurus punctatus Rafinesque, bigmouth buffalo, Ictiobus cyprinellus Valenciennes, grass carp, Ctenopharyngodon idella Valenciennes, and silver carp, Hypophthalmichthys molitrix Valenciennes. In another similar stocked pond, hybrid sunfish fingerlings depressed mosquitofish yield by 79%. No mosquitofish production was obtained in ponds stocked with 250 largemouth bass, Xficropterus salmoides Lacepede, fry …

Attraction Of Aerial Insects As A Fish Food Supplement, Andrew J. Merkowsky, Ambus J. Handcock, Scott H. Newton

Journal of the Arkansas Academy of Science

Insect populations over a 1.2 hectare southeast Arkansas livestock pond were sampled to consider the possibility of their use as a fish food supplement. A commercial insect attraction unit was suspended above the pond, and attracted insects were collected. Insect populations were sampled 3-4 nights each month, January-December, 1976. Insects collected were identified and analyses were performed to determine nutritional composition and pesticide content. Insect samples were variable, however, 62% of the insects identified were in the Order Diptera and 97% of these were in the Family Chironomidae. Nutritional analyses revealed insects were more than 60% crude protein. Pesticide analysis …

The Distribution Of Cane, Arundinaria Gigante (Poaceae: Bambusoideae), Daniel L. Marsh

Journal of the Arkansas Academy of Science

The distribution of cane in the United States was compiled on a county basis from previous records, correspondence, and field work. Ecological correlations were considered. The range appears to be limited primarily by temperature and precipitation. Two geographic populations correlate with major drainage divisions. The broad ecologic amplitude of cane is indicated by its occurrence in many different community types.

Cave Fauna Of Arkansas: Vertebrate Taxa, V. Rick Mcdaniel, James E. Gardner

Journal of the Arkansas Academy of Science

The second in a series of papers describing the fauna of Arkansas caves includes distributional records and ecological status (as a cavernicole) of 53 vertebrate taxa, including: 3 fishes, 7 salamanders, 6 frogs, 3 lizards, 7 snakes, one turtle, 3 birds, and 23 mammals. Several of the taxa occur on state lists of endangered species, but records accumulated during the past 5 years indicate the need for a reevaluation of the actual populational status of these organisms.

Growth, Mortality, Food Habits, And Fecundity Of The Buffalo River Smallmouth Bass, Raj V. Kilambi, Walter R. Robison, James C. Adams

Journal of the Arkansas Academy of Science

Total length-scale radius, and length-weight relationships were determined for smallmouth bass from the Buffalo River. The back calculated lengths were used in analyzing the age-length data by the Bertalanffy growth formula. Asymptotic length and weight were estimated as 58.3 cm and 4.6 lbs, respectively. Annual mortality of 36 percent was estimated by the catch curve method. Insects (54%), fishes (16%), and crayfish (14%) were the abundant food organisms by frequency of occurrence; while fishes (64%) and crayfish (29%) were the dominant food items by the gravimetric method. Based on the gonosomatic indices and frequency distribution of ovum diameter measurements, smallmouth …

Fishes Of The Eleven Point River Within Arkansas, Michael B. Johnson, John K. Beadles

Journal of the Arkansas Academy of Science

A survey of the fishes of the Eleven Point River and its tributaries was made between 31 January 1976 and 13 February 1977. Sixty-three collections, literature records and personal communications revealed 90 species distributed among 19 families. This study revealed 31 species previously not reported for this river system. The Eleven Point River is a clear, predominantly springfed Ozark stream which is located in western Randolph County. From the Arkansas-Missouri state line, the Eleven Point River flows south for approximately 64 km before joining the Spring River. Terrain in the Arkansas portion of this river is rugged as the river …

Utilization Of Nest Boxes By The Southern Flying Squirrel, Glaucomys Volans, In Central Arkansas, Gary A. Heidt

Journal of the Arkansas Academy of Science

Thirty-five nest boxes were placed 4.5-5.5 meters above the ground in an eight acre mixed pine-hardwood plot 20 km SE of Bryant, Saline County, Arkansas. These boxes were monitored from February, 1972, to May, 1975. Flying squirrels used the boxes between October and May, probably returning to den trees during the hotter period of the year. A total of 30 squirrels (18 males and 12 females) were marked by ear notching during the three year period. The winter population of the study area was estimated to be between 10 and 15 squirrels. It was not uncommon to find eight or …

Fishes Of Crowley's Ridge In Arkansas, Robert F. Fulmer, George L. Harp

Journal of the Arkansas Academy of Science

Crowley's Ridge is one of the six natural geographic divisions of Arkansas which rises out of the Mississippi embayment as a relatively steep, uncultivated loessial mass. The ridge is drained by a network of headwater streams which are relatively clear with alkaline pH values and uniformly low alkalinity values. Carbon dioxide values were moderate and oxygen values were adequate. The fish species collected were basically headwater in composition. Isolated groups of characteristically upland species indicate that environmental quality of adjacent deltaic streams was better at one time.
