A Scanning Electron Microscopy Study Of Taxus Leaves As Related To Taxonomy, G.A. Strobel, W. M. Hess

Scanning Microscopy

Scanning electron microscopy, when applied to the surfaces of the needles of Taxus spp. (yew) revealed features that appear useful in the taxonomy of this tree species which yields the important anticancer drug, taxol. For instance, all of the four North American species have 3-5 rows of stomata on one-half of the abaxial leaf surface, whereas all of the others, including those from Europe and Asia, have 7-10 rows of stomata. The appearance of individual or fused papilliform epidermal cells and their arrangement on the leaf surface also is a feature that varies between species. Patterns of wax formation appeared …

Pre-Embedding Staining Of Single Muscle Fibers For Light And Electron Microscopy Studies Of Subcellular Organization, Evelyn Ralston, Thorkil Ploug

Scanning Microscopy

Skeletal muscle fibers are large, multinucleated cells which pose a challenge to the morphologist. In the course of studies of the distribution of the glucose transporter GLUT4, in muscle, we have compared different preparative procedures, for both light (LM) and electron microscopy (EM) immunocytochemistry. Here we show that pre-embedding staining of single teased fibers, or of single enzymatically dissociated fibers, has several advantages over the use of sections for observing discrete patterns that extend over long distances in the cells. We report on an optimization study carried out to establish fixation and permeabilization conditions for EM immunogold labeling of the …

X-Ray Microscopy: Preparations For Studies Of Frozen Hydrated Specimens, A. Osanna, C. Jacobsen, A. Kalinovsky, J. Kirz, J. Maser, S. Wang

Scanning Microscopy

X-ray microscopes provide higher resolution than visible light microscopes. Wet, biological materials with a water thickness of up to about 10 μm can be imaged with good contrast using soft X-rays with wavelengths between the oxygen and carbon absorption edges (at 24 and 43 Å). The Stony Brook group has developed and operates a scanning transmission X-ray microscope (STXM) at the National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory. The microscope is used for imaging with a current resolution of 50 nm, and for elemental and chemical state mapping.

Radiation damage imposes a significant limitation upon high resolution X-ray …

Issues Concerning The Eradication Or Establishment And Biological Control Of The Mediterranean Fruit Fly, Ceratitis Capitata(Wiedemann) (Diptera: Tephritidae), In California, David H. Headrick, Richard D. Goeden

Horticulture and Crop Science

Classical biological control is suggested as a tool worth developing now for possible future use in the integrated pest management of the Mediterranean fruit fly (Medfly), Ceratitis capitata (Wiedemann), in California. Three factors that impact broadly on developing and implementing such a biological control program are: (1) the question of Medfly establishment, (2) quarantine considerations, and (3) agricultural and urban concerns. Each of these factors and their combined effects must be considered when discussing biological control of Medfly in California as shaped by historical perspectives on Medfly invasions, methods of Medfly eradication, and past biological control efforts against Medfly. We …

Longitudinal Studies Of Viral Sequence, Viral Phenotype, And Immunologic Parameters Of Human Immunodeficiency Virus Type 1 Infection In Perinatally Infected Twins With Discordant Disease Courses, Cecelia Hutto, Yi Zhou, Jun He, Rebeca Geffin, Martin Hill, Walter Scott, Charles Wood

Nebraska Center for Virology: Faculty Publications

Perinatal human immunodeficiency virus type 1 (HIV-1) infections cause a broad spectrum of clinical disease and are variable in both the age of the patient at onset of serious disease and the progression of the clinical course. Heterozygotic perinatally infected twins with a marked difference in their clinical courses were monitored during the first 2 years of life. Twin B, the second-born twin, developed AIDS by 6 months of age and died at 22 months of age, while twin A remained minimally symptomatic through the first 2 years. Sequential blood specimens were obtained from the twins in order to characterize …

Reproductive Ecology, Population Genetics, And Clonal Distribution Of The Narrow Endemic: Mirabilis Macfarlanei (Nyctaginaceae), Jennifer L. Barnes

Biology

I examined the reproductive biology and population genetics of the narrow endemic, Mirabilis macfarlanei (Nyctaginaceae) Constance and Rollins, from the Snake and Salmon Rivers in Idaho and Oregon. The results of this study provide further evidence for the proposed effects of rarity on plant reproductive systems and population genetics. Breeding system results indicated that M. macfarlanei is self-compatible, but requires a pollen vector for fertilization. Seed set was not pollen limited, but may be resource limited during others. The major floral visitors were long-tongued bees such as Anthophora spp. and Bombus spp., unlike other species of Mirabilis, which are …

The Relationship Between The Fibrinogen D Domain Self-Association/Cross-Linking Site (Gammaxl) And The Fibrinogen Dusart Abnormality (Aalpha R554c-Albumin): Clues To Thrombophilia In The "Dusart Syndrome", Michael W. Mosesson, Kevin R. Siebenlist, James F. Hainfeld, J. S. Wall, C. Soria, J. P. Caen

Biomedical Sciences Faculty Research and Publications

Cross-linking of fibrinogen at its COOH-terminal gamma chain cross-linking site occurs in the presence of factor XIIIa due to self-association at a constitutive D domain site ("gammaXL"). We investigated the contribution of COOH-terminal regions of fibrinogen Aalpha chains to the gammaXL site by comparing the gamma chain cross-linking rate of intact fibrinogen (fraction I-2) with that of plasma fraction I-9, plasmic fraction I-9D, and plasmic fragment D1, which lack COOH-terminal Aalpha chain regions comprising approximately 100, approximately 390, and 413 residues, respectively. The cross-linking rates were I-2 > I-9 > 1-9D = D1, and indicated that the terminal 100 or more Aalpha …

Trypanoplasma Atraria Sp. N. (Kinetoplastida: Bodonidae) In Fishes From The Sevier River Drainage, Utah, J. Stephen Cranney, Richard A. Heckmann

Great Basin Naturalist

A total of 181 fishes belonging to 10 species were captured near Richfield, Utah, and examined for parasites. A new species of hemoflagellate, Trypanoplasma atraria sp. n., was observed in 3 species: Utah chub (Gila atraria [Girard]), redside shiner (Richardsonius balteatus [Richardson]), and speckled dace (Rhinichthys osculus [Girard]). Seven other species of fishes examined in the study area were negative for T. atraria sp. n. The salmonid leech, Piscicola salmositica (Meyer), collected in the same area harbored developmental stages of Trypanoplasma, suggesting a possible leech vector for the hemoflagellate. Characteristics of Trypanoplasma atraria sp. n. place …

Imaging Molecular Structure Of Channels And Receptors With An Atomic Force Microscope, Ratneshwar Lal

Scanning Microscopy

Biological membranes contain specialized protein macromolecules such as channels, pumps and receptors. Physiologically, membranes and their constituent macromolecules are the interface surfaces toward which most of the regulatory biochemical and other signals are directed. Yet very little is known about these surfaces. The structure of biological membranes has been analyzed primarily using imaging techniques that are limited in their resolution of surface topology. An atomic force microscope (AFM) developed by Binnig, Quate and Gerber, can image molecular structures on specimen surfaces with subnanometer resolution, under diverse environmental conditions. Also, AFM can manipulate surfaces with molecular precision: it can nanodissect, translocate, …

The Construction Of Effective Cooperative Learning Groups For Successful High School Biology Instruction, Diana I. Probasco

Theses and Dissertations

The purpose of this project was to determine the effect of balancing learning styles in the construction of cooperative learning groups. The investigation attempted to determine if science instruction and subsequent achievement can be enhanced by establishing effective cooperative learning groups. The Learning Style Inventory was used to determine learning styles. Then groups were formed based on either construction of balanced or unbalanced cooperative learning groups. Students then completed group activities as contained in the Celebrate Immunity Team Pack. Pretests and posttests were administered in order to measure cognitive gains. A statistical analysis of the results of the groups showed …

The Interface And Characterization Of An Lfesr Spectrometer And Preliminary Study To Detect Ultrasound Induced Radicals By Lfesr Spectroscopy, William Ryan

Theses

A modular low frequency electron spin resonance (LFESR) spectrometer has been interfaced, characterized, and applied in a test to detect ultrasound-induced free radicals with low frequency ESR spectroscopy The modular system, which operates at -250 MHz, was interfaced with a 486DX2 66 MHz PC, using a multifunction PC compatible interface board to facilitate integrated software control of the modular components. The operating software was programmed in Microsoft Visual C++ to execute in the Windows operating environment. Computer control of the magnet was calibrated, using the 2,5-di-tert-butyl parabenzosemiquinone anion radical as a gfactor and hyperfine splitting standard. Preparation of the semiquinone …
