Nomenclatural Changes For Some Grasses In California And The Muhlenbergia Clade (Poaceae), J. Travis Columbus, James P. Smith Jr.

Aliso: A Journal of Systematic and Floristic Botany

New combinations and names are here validated for ten grass (Poaceae) taxa in California for the forthcoming revision of The Jepson Manual. In addition, guided by recent molecular phylogenetic studies, ten non-California grass species are here transferred to Muhlenbergia (Chloridoideae: Cynodonteae) to achieve monophyly of the genus. Lolium, long known to be phylogenetically nested within Festuca, is here subsumed into Festuca, and the circumscription of Stipa is expanded to include all Stipeae (native and non-native) in California. In Stipeae, most currently recognized genera are not monophyletic. Attaining monophyly while bearing in mind identification for persons not expert …

High Amino Acid Diversity And Positive Selection At A Putative Coral Immunity Gene (Tachylectin-2), Marshall L. Hayes, Ron I. Eytan, Michael E. Hellberg

Faculty Publications

Background. Genes involved in immune functions, including pathogen recognition and the activation of innate defense pathways, are among the most genetically variable known, and the proteins that they encode are often characterized by high rates of amino acid substitutions, a hallmark of positive selection. The high levels of variation characteristic of immunity genes make them useful tools for conservation genetics. To date, highly variable immunity genes have yet to be found in corals, keystone organisms of the world's most diverse marine ecosystem, the coral reef. Here, we examine variation in and selection on a putative innate immunity gene from Oculina, …

Reduction Of Sympathetic Activity Via Adrenal-Targeted Grk2 Gene Deletion Attenuates Heart Failure Progression And Improves Cardiac Function After Myocardial Infarction., Anastasios Lymperopoulos, Giuseppe Rengo, Erhe Gao, Steven N. Ebert, Gerald W. Dorn, Walter J. Koch

Department of Medicine Faculty Papers

Chronic heart failure (HF) is characterized by sympathetic overactivity and enhanced circulating catecholamines (CAs), which significantly increase HF morbidity and mortality. We recently reported that adrenal G protein-coupled receptor kinase 2 (GRK2) is up-regulated in chronic HF, leading to enhanced CA release via desensitization/down-regulation of the chromaffin cell alpha(2)-adrenergic receptors that normally inhibit CA secretion. We also showed that adrenal GRK2 inhibition decreases circulating CAs and improves cardiac inotropic reserve and function. Herein, we hypothesized that adrenal-targeted GRK2 gene deletion before the onset of HF might be beneficial by reducing sympathetic activation. To specifically delete GRK2 in the chromaffin cells …

Signaling Pathways Coupled To Melatonin Receptor Mt1 In Gastric Smooth Muscle, Rashad Ahmed

Theses and Dissertations

The Melatonin, a close derivative of serotonin, is involved in physiological regulation of circadian rhythms. In the gastrointestinal (GI) system, melatonin exhibits endocrine, paracrine and autocrine actions and is implicated in the regulation of GI motility. Generally, melatonin actions oppose the stimulatory actions of serotonin on motility. However, it is not known whether melatonin can also act directly on GI smooth muscle cells. The aim of the present study was to determine the expression of melatonin receptors in smooth muscle and identify their signaling pathways. Muscle cells were isolated from rabbit distal stomach by enzymatic digestion, filtration and centrifugation and …

Core-Shell Magnetic Morphology Of Structurally Uniform Magnetite Nanoparticles, Kathryn L. Krycka, R.A. Booth, C.R. Hogg, Y. Ijiri, Julie A. Borchers, W.C. Chen, S.M. Watson, M. Laver, T.R. Gentile, Liv R. Dedon

Faculty & Staff Scholarship

A new development in small-angle neutron scattering with polarization analysis allows us to directly extract the average spatial distributions of magnetic moments and their correlations with three-dimensional directional sensitivity in any magnetic field. Applied to a collection of spherical magnetite nanoparticles 9.0 nm in diameter, this enhanced method reveals uniformly canted, magnetically active shells in a nominally saturating field of 1.2 T. The shell thickness depends on temperature, and it disappears altogether when the external field is removed, confirming that these canted nanoparticle shells are magnetic, rather than structural, in origin.

Religious Organizations, Gilat Levy, Ronny Razin

Fondazione Eni Enrico Mattei Working Papers

We propose a model of religious organizations which relies on the ability of such organi-zations and personal utility shocks. We show how religious organizations arise endogenously and characterize their features. Specifically, we find that members of the religious organization share similar beliefs and are more likely to cooperate with one another in social interactions. We identify a "spiritual" as well as a "material" payoff for members of the religious organization. Our results explain and shed light on empirical phenomena such as the effects of secularization and economic development on religious beliefs and participation, the relation between the size of the …

Platform Effects On Optical Variability And Prediction Of Underwater Visibility, Grace Chang, Michael S. Twardowski, Yu You, Mark A. Moline, Peng-Wang Zhai, Scott Freeman, Matthew Slivkoff, Francesco Nencioli, George W. Kattawar

Biological Sciences

We present hydrographic and optical data collected concurrently from two different platforms, the R/P FLoating Instrument Platform and the R/V Kilo Moana, located about 2km apart in the Santa Barbara Channel in California. We show that optical variability between the two platforms was due primarily to platform effects, specifically the breakdown of stratification from mixing by the hull of R/P FLIP. Modeled underwater radiance distribution differed by as much as 50% between the two platforms during stratified conditions. We determine that the observed optical variability resulted in up to 57% differences in predicted horizontal visibility of a black target.

The Nomenclatural Status Of Ten Names In The Genus Pieris (Lepidoptera: Pieridae), Crispin S. Guppy, Norbert G. Kondla

The Taxonomic Report of the International Lepidoptera Survey

The nomenclatural status of ten names in the genus Pieris are reviewed. The dates and locations of publication of pseudobryoniae Verity, 1908 and adalwinda Fruhstorfer, 1909 are corrected; they are infrasubspecific unavailable names.

Rainwater Harvesting And Greywater Treatment Systems For Domestic Application In Ireland, Zhe Li, Fergal Boyle, Anthony Reynolds

Articles

Water shortage has been recognised as one of the key issues facing many countries. Fortunately, there are relatively abundant water resources available in Ireland because of its plenty of rainfall. However, Ireland will inevitably encounter water shortage in the future, especially in urban areas. The water consumption per capita per day in Ireland is one of the highest in Europe. The water demand is still increasing due to population growth and higher standard of living. The use of domestic rainwater harvesting and greywater treatment systems has the potential to supply nearly 94% of domestic water in Irish households. The utilisation …

Evaluation Of Freshwater Mussel Conservation Strategies At Multiple Scales: Macro-Molecules,Behavior, Habitat, And Policy., Andrew J. Peck

Student Theses and Dissertations

Freshwater mussels are the second most imperiled taxonomic group in North America. In the United States, the most threatened mussel species receive special protection under the Endangered Species Act, among others, which requires implementation of a conservation action strategy to ameliorate potential impacts to protected populations and their habitats. This dissertation evaluates the response of freshwater mussels, through condition indicators, individual behavior, and community metrics, to conservation strategies. The first strategy evaluated is the effect of relocation on an endangered mussel species, Potamilus capax (Green 1832). As relocation requires identification of safe harbor habitats, a methodology is proposed to identify …

The Nhanes Iii Database: Design And A Retrospective Study To Identify Associations Between Vitamin D And Hypertension, Brandon J. Marzullo

Theses

The results from government surveys are often available wholly or in part to the general public. However the format of this information is not always optimal for distribution or analysis, the National Health and Nutrition Examination Survey III, NHANES III, is one such example. This survey is released as data sets containing a Statistical Analysis Software (SAS) program, a column delimited data file, and documentation. This limits access to the data by requiring a license to read in and query the data. By taking the data in its available format and parsing it into a MySQL database the wealth of …

Gc-Biased Evolution Near Human Accelerated Regions, Sol Katzman, Andrew D. Kern, Katherine S. Pollard, Sofie R. Salama, David Haussler

Dartmouth Scholarship

Regions of the genome that have been the target of positive selection specifically along the human lineage are of special importance in human biology. We used high throughput sequencing combined with methods to enrich human genomic samples for particular targets to obtain the sequence of 22 chromosomal samples at high depth in 40 kb neighborhoods of 49 previously identified 100–400 bp elements that show evidence for human accelerated evolution. In addition to selection, the pattern of nucleotide substitutions in several of these elements suggested an historical bias favoring the conversion of weak (A or T) alleles into strong (G or …

Social Networking: A Boon To Criminals, Tejashree D. Datar, Richard Mislan

Annual ADFSL Conference on Digital Forensics, Security and Law

With the world getting more and more digitized, social networking has also found a place in the cyber world. These social networking sites (SNSs) which enable people to socialize, and build and maintain relationships are attracting attention of all kinds of people such as teens, adults, sports persons, and even businesses. But these SNSs are also getting unwanted attention from people like sexual predators, spammers, and people involved in criminal and illegal activities. This paper talks about SNSs and how these sites are exploited for criminal or illegal activity. The SNSs are discussed in detail with respect to user profiles, …
