Acute Clinical Disease In Cats Following Infection With A Pathogenic Strain Of Bartonella Henselae (Lsu16), Kathy L. O'Reilly, Rudy W. Bauer, Rebecca L. Freeland, Lane D. Foil, Keith J. Hughes, Kristen R. Rohde, Alma F. Roy, Rhett W. Stout, Patricia C. Triche

Faculty Publications

Bartonella henselae is the causative agent of human cat scratch disease as well as several serious sequelae of infections, including bacillary angiomatosis and bacillary peliosis. Conflicting reports describe the pathogenesis of B. henselae in the cat. In this study, we characterized a strain of B. henselae termed LSU16. This strain was isolated on rabbit blood agar from a naturally infected 10-month-old female cat during a recurrent episode of bacteremia. The bacterial species was confirmed by PCR- restriction fragment length polymorphism analysis. Nine cats were infected intradermally with 5 x 107 CFU of LSU16, and clinical signs, antibody responses, and bacteremia …

Separation Of Saturated And Unsaturated Free Fatty Acids Using Capillary Electrophoresis With Indirect Photometric Detection, F. Haddadian, S. A. Shamsi, I. M. Warner

Faculty Publications

The capillary zone electrophoresis separation of various mixtures of saturated and unsaturated free fatty acids (FFAs) is performed using adenosine monophosphate (AMP) as an indirect photometric detection reagent. The presence of Brij in the electrolyte and a temperature of 40°C in the running buffer are required to improve solubility of the very long chain FFAs. The separation of C12-C31 differing by only one carbon is achieved using N-methylformamide (NMF)-dioxane (3:2), 40mM Tris, 2.5mM AMP, and 0.5% (w/v) Brij in approximately 40 min. However, baseline resolution of unsaturated isomers of FFAs (C14-C22) requires the presence of water, because water enhances the …

Zim1, A Maternally Expressed Mouse Kruppel-Type Zinc-Finger Gene Located In Proximal Chromosome 7, Joomyeong Kim, Xiaochen Lu, Lisa Stubbs

Faculty Publications

In analysis of a conserved region of proximal mouse chromosome 7 and human chromosome 19q, we have isolated a novel mouse gene, Zim1 (imprinted zinc-finger gene 1), encoding a typical Kruppel-type (C2H2) zinc-finger protein, located within 30 kb of a known imprinted gene, Peg3 (paternally expressed gene 3). Our studies demonstrate that Zim1 is also imprinted; the gene is expressed mainly from the maternal allele and at high levels only during embryonic and neonatal stages. In contrast to most tissues, Zim1 is expressed biallelically in neonatal and adult brain with slightly more input from the maternal allele. Zim1 produces multiple …

Ferric Iron Reduction By Bacteria Associated With The Roots Of Freshwater And Marine Macrophytes, G. M. King, Meredith A. Garey

Faculty Publications

In vitro assays of washed, excised roots revealed maximum potential ferric iron reduction rates of >100 μmol g (dry weight)-1 day-1 for three freshwater macrophytes and rates between 15 and 83 μmol (dry weight)-1 day-1 for two marine species. The rates varied with root morphology but not consistently (fine root activity exceeded smooth root activity in some but not all cases). Sodium molybdate added at final concentrations of 0.2 to 20 mM did not inhibit iron reduction by roots of marine macrophytes (Spartina alterniflora and Zostera marina). Roots of a freshwater macrophyte, Sparganium eurycarpum, that were incubated with an analog …

Complementation Of Conjugation Functions Of Streptomyces Lividans Plasmid Pij101 By The Related Streptomyces Plasmid Psb24.2, Gregg S. Pettis, Shubha Prakash

Faculty Publications

A database search revealed extensive sequence similarity between Streptomyces lividans plasmid pIJ101 and Streptomyces plasmid pSB24.2, which is a deletion derivative of Streptomyces cyanogenus plasmid pSB24.1. The high degree of relatedness between the two plasmids allowed the construction of a genetic map of pSB24.2, consisting of putative transfer and replication loci. Two pSB24.2 loci, namely, the cis-acting locus for transfer (clt) and the transfer-associated korB gene, were shown to be capable of complementing the pIJ101 clt and korB functions, respectively, a result that is consistent with the notion that pIJ101 and the parental plasmid pSB24.1 encode highly similar, if not …

Rapid Evolution Of Fertilization Selectivity And Lysin Cdna Sequences In Teguline Gastropods, Michael E. Hellberg, Victor D. Vacquier

Faculty Publications

Proteins mediating intercellular recognition face opposing selective forces as they evolve: purifying selection to maintain function, and diversifying selection to alter specificity. Lysin is a 16-kDa protein which enables sperm of free-spawning marine snails to make a hole in the vitelline layer (VE) surrounding conspecific eggs. Previous work on abalone (Haliotis spp.) has shown that positive selection promotes rapid interspecific divergence of lysin. Here, we present data on the specificity of VE dissolution by four species of teguline gastropods, along with lysin cDNA sequences. The teguline and abalone lineages diverged over 250 MYA. As in abalone, VE dissolution by lysin …

Socioeconomic Status And Morbidity In The Last Years Of Life, Youlian Liao, Daniel L. Mcgee, Jay S. Kaufman, Guichan Cao, Richard S. Cooper

Faculty Publications

Objectives. This study evaluated the effect of socioeconomic status, as characterized by level of education, on morbidity and disability in the last years of life. Methods. The analysis used data from the National Health Interview Survey (1986-1990), with mortality follow-up through December 1991. Results. Among 10 932 decedents 50 years or older at baseline interview, educational attainment was inversely associated with long-term limitation of activity, number of chronic conditions, number of bed days, and days of short hospital stay during the year preceding the interview. Conclusions. Decedents with higher socioeconomic status experienced lower morbidity and disability and better quality of …

Maximum-Likelihood Generalized Heritability Estimate For Blood Pressure In Nigerian Families, Charles N. Rotimi, Richard S. Cooper, Guichan Cao, Olufemi Ogunbiyi, Modupe Ladipo, Eme Owoaje, Ryk Ward

Faculty Publications

Elevated blood pressure (BP) is more common in relatives of hypertensives than in relatives of normotensives, indicating familial resemblance of the BP phenotypes. Most published studies have been conducted in westernized societies. To assess the ability to generalize these estimates, we examined familial patterns of BP in a population-based sample of 510 nuclear families, including 1552 individuals (320 fathers, 370 mothers, 475 sons, and 387 daughters) from Ibadan, Nigeria. The prevalence of obesity in this community is low (body mass index: fathers 21.6; mothers, 23.6; sons, 19.2; and daughters=21.0 kg/m2). The BP phenotype used in all analyses was created from …

Faculty Publications

By virtue of its potential effects on rates of energy expenditure, uncoupling protein 3 (UCP3) is an obesity candidate gene. We identified nine sequence variants in UCP3, including Va19Met, Val102Ile, Arg282Cys, and a splice site mutation in the intron between exons 6 and 7. The splice mutation results in an inability to synthesize mRNA for the long isoform (UCP3L) of UCP3. Linkage (sib pair), association, and transmission disequilibrium testing studies on 942 African-Americans did not suggest a significant effect of UCP3 on body composition in this group. In vastus lateralis skeletal muscle of individuals homozygous for the splice mutation, no …

Effects Of Heat-Sensitive Agents, Soil Type, Moisture, And Leaf Surface On Persistence Of Anticarsia Gemmatalis (Lepidoptera: Noctuidae) Nucleopolyhedrovirus, F. Peng, J. R. Fuxa, A. R. Richter, S. J. Johnson

Faculty Publications

In a laboratory experiment, persistence of Anticarsia gemmatalis Hubner nucleopolyhedrovirus (AgNPV) was significantly lower in marsh soil than in agricultural soil. AgNPV was inactivated significantly more quickly in soil at -0.3 bar water potential than in soil at water potentials of 0 bar or -5 bar. Loss of AgNPV activity was significantly faster in unautoclaved soil than in autoclaved soil. AgNPV stored in unautoclaved marsh water lost 99% of its activity within 64 d, whereas AgNPV in distilled water or autoclaved marsh water remained 98-99% active after the same time period. The soil and marsh-water results indicate that 1 or …

Influence Of Calcium Silicate And Sterilization On The Natural Suppressiveness And On The Conduciveness Of Two Soils To Rhizoctonia Solani, Fabrício De Ávila Rodrigues, Gilberto Fernandes Corrêa, Caspar Henrique Korndörfer, Maria Amelia Dos Santos, Lawrence Elliot Datnoff

Faculty Publications

The effect of calcium silicate slag and soil sterilization on the natural suppressiveness of a Typic Acrustox (clay Dark Red Latosol - LEa) and the natural conduciveness of an Oxic Haplustoll (TRe) to Rhizoctonia solani were studied under greenhouse conditions. The experimental design was a three-replicate completely randomized one, with 2 × 3 × 2 factorial combination of the following treatments: two soil kinds (LEa and TRe, collected at 0-20 cm layer); three treatments with and without soil sterilization, calcium silicate slag and nontreated control; and uninfested and infested with R. solani. Each soil material was infested previously with 800 …

Susceptibility Of Different Instars Of European Corn Borer (Lepidoptera: Crambidae) To Diet Containing Bacillus Thuringiensis, Fangneng Huang, Lawrent L. Buschman, Randall A. Higgins

Faculty Publications

The relative susceptibility of different instars of the European corn borer, Ostrinia nubilalis (Hubner), to a commercial formulation of Bacillus thuringiensis Berliner subsp. kurstaki, Dipel ES, was determined using diet incorporation. European corn borers exposed to Dipel during the 1st instar were much more susceptible than were older larvae. No significant differences in susceptibility were found among 3rd, 4th, and 5th instars at doses of 0.03-0.81 ml of Dipel per kilogram of diet. At high concentrations (2.43 ml/km of diet), 5th instars had significantly lower mortality than did 3rd or 4th instars. The LC50 and LC90 of the 5th instars …

Physicochemical Influences On Parasites Of Age-0 Largemouth Bass In The Atchafalaya River Basin, Louisiana, Randy C. Landry, William E. Kelso

Faculty Publications

We investigated prevalence and intensity patterns of nine parasite taxa in 244 age-0 largemouth bass (Micropterus salmoides) collected from lake (high dissolved oxygen levels), riverine (high current velocities), and swamp (hypoxic canals and bayous) sites (N=6) in the Atchafalaya River Basin during the 1996 flood pulse. Ectoparasites were dominated by monogenetic trematodes (prevalence=100%; median intensities 27–91 per host) and glochidia (prevalence > 96% at all sites, median intensities 47–148 per host), whereas Posthodiplostomum minimum (Trematoda), Caecincola spp. (Trematoda; C. parvulus and perhaps C. latostoma), Neoechinorhynchus cylindratus (Acanthocephala), and Proteocephalus ambloplitis (Cestoda) accounted for 94.6% of bass endoparasites. Overall, lake sites supported …

Bird Communities In Two Types Of Anthropogenic Successional Vegetation In Central Amazonia, Sérgio Henrique Borges, Philip C. Stouffer

Faculty Publications

When primary forest in central Amazonia is cut and abandoned, the plant succession is dominated by Cecropia spp., whereas when it is cut and burned for pastures, the regrowth vegetation is dominated by Vismia spp. The bird communities of these two regrowth forest types were sampled at six sites (9-13 years old) using mist-nets and observations. Bird species richness was similar between the two forest types. Cecropia regrowth, however, was richer for strictly forest bird species than was Vismia regrowth. Mixed-flock species and ant-following birds were significantly more abundant in the Cecropia second growth, whereas nonforest insectivores and omnivores were …

The Expressive Function Of Succession Law And The Merits Of Non-Marital Inclusion, E. Gary Spitko

Faculty Publications

Intestacy statutes seek to further donative freedom by effectuating the attributed intent of those who fail to execute a valid estate plan during life. One might reasonably hypothesize that gay men and lesbians, on the whole, differ from the non-gay majority with respect to their donative intent. The fundamental difference in romantic and affectional preferences between gay people and non-gay people is likely to produce such a disparate donative intent. Much anecdotal evidence and recent empirical evidence strongly support this hypothesis.

Article II of the Uniform Probate Code presently ignores the existence of gay men and lesbians, despite the drafters' …

Judge Not: In Defense Of Minority-Culture Arbitration, E. Gary Spitko

Faculty Publications

Arbitration can serve as a necessary safe harbor from procedural and substantive cultural bias in the general public courts. Arbitration also can serve as a laboratory for process reforms as cultural minorities attempt to craft rules that better govern their lives than do the purportedly “one size fits all” rules that the majority has crafted. In so allowing cultural minorities to structure their lives and legal disputes in ways that reflect their particular needs, minority-culture arbitration also has great potential for habituating the general public to the realities of the lives of cultural minorities and to the notion that custom-made …

Effects Of Competition On Resource Availability And Growth Of A California Bunchgrass, Andrew R. Dyer, Kevin J. Rice

Faculty Publications

In California, little is known about the sensitivity of native bunchgrasses to competition or to changes in resource availability. We investigated the effect of nonnative annual vegetation on resource availability and growth of a native bunchgrass, Nassella pulchra, in a pair of factorial field experiments that incorporated effects of both interspecific and intraspecific competition as well as variation in soil depth. Plots of differing target densities and neighborhoods were used to assess changes in aboveground (light) and belowground (water) resource availability over multiple seasons in two sites with differing soil depth. N. pulchra grown without interspecific competitors grew larger …

Clear And Present Danger: Enforcing The International Ban On Biological And Chemical Weapons Through Sanctions, Use Of Force, And Criminalization, Michael P. Scharf

Faculty Publications

Currently there are two means of enforcing the international prohibition of chemical and biological weapons. First, the international community can induce compliance through imposition of sanctions, such as trade embargoes, freezing of assets and diplomatic isolation. Second, when sanctions fail, States can individually or collectively respond to the threat of chemical or biological weapons by using military force. After exploring the potential strengths and weaknesses of these approaches, this article examines the desirability of supplementing them with a third approach based on the criminal prosecution of persons responsible for the production, stockpiling, transfer, or use of chemical and biological weapons.

How Children In Cults May Use Emancipation Laws To Free Themselves, Robin A. Boyle

Faculty Publications

The author examines how children who are born into cults or brought into them at a young age can use state emancipation laws to gain independence when they are in their mid-teens, so long as they can demonstrate criteria that their states have established. Commonly, states require a showing that the minor has achieved some level of economic self-sufficiency and can live emotionally and physically independently from his or her parents. There are some difficulties for cultic children in demonstrating these criteria, but the obstacles are not insurmountable.

Dam Nation: A Geographic Census Of American Dams And Their Large-Scale Hydrologic Impacts, William L. Graf

Faculty Publications

Newly available data indicate that darns fragment the fluvial system of the continental United States and that their impact on river discharge is several times greater than impacts deemed likely as a result of global climate change. The 75,000 dams in the continental United States are capable of storing a volume of water almost equaling one year's mean runoff, but there is considerable geographic variation in potential surface water impacts. In some western mountain and plains regions, darns can store more than 3 year's runoff, while in the Northeast and Northwest, storage is as little as 25% of the annual …

Health-Promoting Properties Of Common Herbs, Winston J. Craig

Faculty Publications

Herbs have been used as food and for medicinal purposes for centuries. Research interest has focused on various herbs that possess hypolipidemic, antiplatelet, antitumor, or immune-stimulating properties that may be useful adjuncts in helping reduce the risk of cardiovascular disease and cancer. In different herbs, a wide variety of active phytochemicals, including the flavonoids, terpenoids, lignans, sulfides, polyphenolics, carotenoids, coumarins, saponins, plant sterols, curcumins, and phthalides have been identified. Several of these phytochemicals either inhibit nitrosation or the formation of DNA adducts or stimulate the activity of protective enzymes such as the Phase II enzyme glutathione transferase (EC 2.5.1.18).
