Hematite And Calcite Coatings On Fossil Vertebrates, Huiming Bao, Paul L. Koch, Robert P. Hepple

Faculty Publications

Hematite coatings are common on vertebrate fossils from Paleocene/Eocene paleosol deposits in the Bighorn Basin, Wyoming. In general, hematite coatings are found only on fossils and are limited to soils exhibiting hydromorphic features and moderate maturity. Petrographic and isotopic evidence suggests that hematite and micritic calcite formed at nearly the same time in a pedogenic environment, whereas sparry calcite formed later at greater burial depths. The parent material of paleosols is rich in iron, supplying an ample source of iron for hematite formation. Decomposition of animal tissues around bones may enhance the weathering of iron-bearing minerals in soils surrounding carcasses, …

Working Wrongly And Seeking The Straight: Remedial Remedies On Enewetak Atoll, Laurence Marshall Carucci

Pacific Studies

Classical approaches to righting wrongs among Pacific societies have been couched in terms of normative models of authority, and particularly in relation to societies with positions of ascribed authority, chiefs, and those with acquired authority like Melanesian center persons (“big-men”). In this article, I contend that typological approaches to the analysis of perceived wrongdoing are of limited utility in the assessment of how wrongdoing is culturally fashioned and socially redressed. Instead, I suggest that constructions of wrongdoing are culturally relative. Moreover, ideas and feelings about just and unjust action within the community are also relative and depend upon varied logical …

Feather Evidence Helps Clarify Locality Of Anthropological Artifacts In The Museum Of Mankind, Carla J. Dove

Pacific Studies

Species of birds used on ethnographic artifacts collected during the eighteenth century and stored at the Museum of Mankind (British Museum) were identified by using microscopic and whole-feather characters. One of the objects (VAN 345), labeled as having been collected on Vancouver’s voyage to Tahiti, was a feather pendant made of long strands of chicken feathers with small red feathers at the base. The small red feathers were examined microscopically, compared with museum study skins of all possible species, and identified as Vestiaria coccinea (‘I‘iwi). Since this species is known only from the Hawaiian Archipelago, it was determined that the …

The Plant Cdna Lct1 Mediates The Uptake Of Calcium And Cadmium In Yeast, Stephen Clemens, Danuta M. Antosiewicz, John M. Ward, Daniel P. Schachtman, Julian I. Schroeder

Department of Agronomy and Horticulture: Faculty Publications

Nonessential metal ions such as cadmium are most likely transported across plant membranes via transporters for essential cations. To identify possible pathways for Cd²⁺ transport we tested putative plant cation transporters for Cd²⁺ uptake activity by expressing cDNAs in Saccharomyces cerevisiae and found that expression of one clone, LCT1, renders the growth of yeast more sensitive to cadmium. Ion flux assays showed that Cd²⁺ sensitivity is correlated with an increase in Cd²⁺ uptake. LCT1-dependent Cd²⁺ uptake is saturable, lies in the high-affinity range (apparent K_M for Cd²⁺ = 33 µM) and is …

Influence Of The Ccr2-V64i Polymorphism On Human Immunodeficiency Virus Type 1 Coreceptor Activity And On Chemokine Receptor Function Of Ccr2b, Ccr3, Ccr5, And Cxcr4, Benhur Lee, Benjamin J. Doranz, Shalini Rana, Yanji Yi, Mario Mellado, Jose M. R. Frade, Carlos Martinez-A., Stephen J. O'Brien, Michael Dean, Ronald G. Collman, Robert W. Doms

Biology Faculty Articles

The chemokine receptors CCR5 and CXCR4 are used by human immunodeficiency virus type 1 (HIV-1) in conjunction with CD4 to infect cells. In addition, some virus strains can use alternative chemokine receptors, including CCR2b and CCR3, for infection. A polymorphism in CCR2 (CCR2-V64I) is associated with a 2- to 4-year delay in the progression to AIDS. To investigate the mechanism of this protective effect, we studied the expression of CCR2b and CCR2b-V64I, their chemokine and HIV-1 coreceptor activities, and their effects on the expression and receptor activities of the major HIV-1 coreceptors. CCR2b and CCR2b-V64I were expressed at …

Regulation Of Connexin43 By Phosphorylation In Heart Development, John C. Duncan

Loma Linda University Electronic Theses, Dissertations & Projects

Serine/threonine protein kinases have been shown to reversibly regulate cell-cell communication through gap junctions formed by connexin 43 (Cx43) (Godwin et al.7 1993). The Cx43 protein expression levels are unclear and what role phosphorylation plays in the regulation of signal transduction through these gap junctions during heart formation. Reportedly, mutations which replace potentially phosphorylatable serines within the Cx43 protein are associated with heart malformations (Britz-Cunningham et al.. 1995), highlighting the importance of determining the levels of Cx43 and the activities of PKA and PKC during heart development.

Western analysis performed on hearts from developmentally significant time points revealed principally high …

Localization Of Sodium, Potassium-Adenosine Triphosphatase In The Cerebral Cortex Of Developing Rats, Maki Ujiie

Loma Linda University Electronic Theses, Dissertations & Projects

Active transport via Na⁺, K⁺-ATPase plays an important role in establishing and maintaining proper ionic gradient across all mammalian cell membranes. A strict regulation of Na⁺, and K⁺ ion levels is especially important in excitable cells such as neurons and myocytes. Inhibition of the enzyme is associated with several pathological conditions and has serious detrimental effects on cerebral cortical cells. Yet the enzyme appears to be limited in amount and distribution in newborn rats. In this study, Na_⁺, K⁺- ATPase expression and distribution in early postnatal rats were studied …

The Relationship Of The Incisive Canal To Maxillary Median Diastema, Jeffery S. Corbett

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to assess the relationship between the incisive canal and maxillary median diastema, and to identify an imaging method capable of documenting the geometry and dimensions of the incisive canal. The sample consisted of 59 dry skulls, 26 of which had a maxillary median diastema ranging in size from 0.1 mm to 2.8 mm (mean 1.0 mm, SD = 0.7 mm). Each skull had all of the permanent maxillary teeth present from first molar to first molar and lacked any apparent non-orthodontic condition that could have caused the diastema. Diastema width and canal diameter were …

The Mortenson Ranch: Cattle And Trees At Home On The Range. A Restoration Guidebook, Susan E. Boettcher, W. Carter Johnson, Scott Kronberg, F. Robert Gartner, Clarence Todd, Jeff Mortenson, Scott Fausti

Natural Resource Management Faculty Publications

Early agriculture on western rangeland met with little success and resulted in serious consequences including soil erosion, loss of native woodlands and wildlife, and economic ruin. The Mortenson family in Stanley County, South Dakota, has been engaged in restoring degraded rangeland on their ranch for more than 50 years. Their primary goal has been to return the land to its condition prior to white settlement while maintaining a profitable cattle ranching operation. In recent years the ranch has served as a model of successful ranching based on a conservation ethic. This guidebook summarizes the restoration techniques and grazing regime used …

Biodegradation Of Atrazine By Agrobacterium Radiobacter J14a And Use Of This Strain In Bioremediation Of Contaminated Soil, J. K. Struthers, K. Jayachandran, T. B. Moorman

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

We examined the ability of a soil bacterium, Agrobacterium radiobacter J14a, to degrade the herbicide atrazine under a variety of cultural conditions, and we used this bacterium to increase the biodegradation of atrazine in soils from agricultural chemical distribution sites. J14a cells grown in nitrogen-free medium with citrate and sucrose as carbon sources mineralized 94% of 50 μg of [¹⁴C-U-ring]atrazine ml^-1 in 72 h with a concurrent increase in the population size from 7.9 x 10⁵ to 5.0 x 10⁷ cells ml^-1. Under these conditions cells mineralized the [ethyl-¹⁴C]atrazine …

Spinal Cord Compression: Histologic Spectrum Of Lesions, I. N. Soomro, N.Kayani N.Kayani, Shahid Pervez, A. S. Hussainy, R. Ahmed, S. Muzaffar, S. A. Aziz, S. H. Hasan

Department of Pathology and Laboratory Medicine

Histologic diagnosis ultimately determines the prognosis and treatment of lesions causing spinal cord compression. Modem imaging techniques have revolutionized the procedure of localizing lesions pre¬senting with signs and symptoms of spinal cord compression. As a result, these lesions are more accessible for fine needle aspiration and biopsy. A quick diagnosis is possible if cytologic preparation is made. Similarly, intraoperative frozen section facility not only provides rapid diagnosis, but also offers oppor tunity of appropriate management decision there and then. Histology in many cases needs help of special stains and immunocytochemistry. This study looks at the histologic spectrum of these lesions, …

Feeding Preferences Of A Generalist Salt-Marsh Crab: Relative Importance Of Multiple Plant Traits, Steven C. Pennings, Thomas H. Carefoot, Erin L. Siska, Margo E. Chase, Teresa A. Page

Ocean Engineering and Marine Sciences Faculty Publications

Few studies have evaluated the relative importance of multiple plant traits to herbivore diet choice, especially with an experimental approach. Moreover, although circumstantial evidence points to plant toughness and silica content as important deter- minents of diet choice, few studies have experimentally demonstrated that these factors actually deter feeding by herbivores. We examined feeding preferences of a generalist salt- marsh crab, Armases cinereum, for all the common angiosperms in its habitat. We took an experimental approach to evaluating the importance of toughness, secondary chemistry, silica, salt, and protein in determining feeding preferences. Consumption of plants by Armases in two experiments …

Pediatric Environmental Health Hazards And The Role Of Government In Adopting Standards To Protect Children, Jennifer Brown

Pace Environmental Law Review

Children are particularly vulnerable to environmental hazards due to their biological sensitivities, unique dietary habits and distinctive behavioral patterns, and yet are frequently not factored into the risk assessment process when it comes to environmental regulations. As a result, risk assessments fall short of creating environmentally safe levels of pollutants for children. . - This Comment provides an overview of the current pediatric environmental health initiatives being developed at the national level and illustrates how numerous research endeavors, conferences, newly formed federal offices, legislation and policies have not only brought this issue to the forefront of national attention, but have …

Alternative Splicing Of The Latency-Related Transcript Of Bovine Herpesvirus 1 Yields Rnas Containing Unique Open Reading Frames, Laxminarayana R. Devireddy, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

The latency-related transcript (LRT) of bovine herpesvirus 1 (BHV-1) is the only abundant viral RNA detected during latency. A previous study (A. Hossain, L. M. Schang, and C. Jones, J. Virol. 69:5345–5352, 1995) concluded that splicing of polyadenylated [poly(A) ⁺] and splicing of nonpolyadenylated [poly(A) ^-] LRT are different. In this study, splice junction sites of LRT were identified. In trigeminal ganglia of acutely infected calves (1, 7, or 15 days postinfection [p.i.]) or in latently infected calves (60 days p.i.), alternative splicing of poly(A) ⁺ LRT occurred. Productive viral gene expression in trigeminal ganglia is readily detected …

Radial Distribution Of Electron Spectra From High-Energy Ions, Francis A. Cucinotta, Robert Katz, John W. Wilson

Robert Katz Publications

The average track model describes the response of physical and biological systems using radial dose distribution as the key physical descriptor. We report on an extension of this model to describe the average distribution of electron spectra as a function of radial distance from an ion. We present calculations of these spectra for ions of identical linear energy transfer (LET), but dissimilar charge and velocity to evaluate the differences in electron spectra from these ions. To illustrate the usefulness of the radial electron spectra for describing effects that are not described by electron dose, we consider the evaluation of the …

Cloning And Expression Of The Listeria Monocytogenes Scott A Ptsh And Ptsi Genes, Coding For Hpr And Enzyme I, Respectively, Of The Phosphotransferase System, Douglas P. Christensen, Andrew K. Benson, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

The phosphoenolpyruvate (PEP)-dependent phosphotransferase system (PTS) utilizes high-energy phosphate present in PEP to drive the uptake of several different carbohydrates in bacteria. In order to examine the role of the PTS in the physiology of Listeria monocytogenes, we identified the ptsH and ptsI genes encoding the HPr and enzyme I proteins, respectively, of the PTS. Nucleotide sequence analysis indicated that the predicted proteins are nearly 70% similar to HPr and enzyme I proteins from other organisms. Purified L. monocytogenes HPr overexpressed in Escherichia coli was also capable of complementing an HPr defect in heterologous extracts of Staphylococcus aureus ptsH …

Residual Effects Of Crop Residues On Grain Production And Selected Soil Properties, James F. Power, Paul Koerner, John W. Doran, Wallace Wilhelm

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

Returning crop residue improves water conservation and storage, nutrient availability, and crop yields. We have little knowledge, however, of the residual impacts of crop residues on soil and crop production. We hypothesized that residual impacts of crop residues vary with the amount of residues used. A 10-yr study near Lincoln, NE, evaluated the residual effects of an earlier 8-yr study of various crop residue amounts on crop growth and selected soil properties. From 1978 through 1985, crop residues were returned at 0,50, 100, and 150% of the quantity produced by the previous crop (averaging 0 to =6 Mg ha^{-1 …}

Knowledge Utilization In Social Work And Legal Practice, Karen M. Staller, Stuart A. Kirk

The Journal of Sociology & Social Welfare

The gap between knowledge generated by systematic inquiry and its eventual use by practitioners has been a concern in social work for several decades. Explanations for the gap have been identified as the orientation or attitudes of practitioners, the character of professional education, and the nature of scientific inquiry. The structural character of both practice itself and its knowledge base have been overlooked as an explanation. By comparing legal and social work practice, we suggest that characteristics of social work practice and knowledge also impede research utilization.
