The Role Of Nf-Kb Activation In Hepatic Tumor Promotion By Polycholorinated Biphenyls (Pcbs), Zijing Lu Jan 2002

The Role Of Nf-Kb Activation In Hepatic Tumor Promotion By Polycholorinated Biphenyls (Pcbs), Zijing Lu

University of Kentucky Doctoral Dissertations

Polychlorinated biphenyls (PCBs) are nongenotoxic hepatic tumor promoters. PCBs have been shown to cause oxidative stress, but the exact mechanism by which PCBs exert their tumor promoting activity is not clear. In our study, PCB-153, a non-coplanar congener, caused a transient increase in hepatic NF-B DNA binding activity and cell proliferation, while PCB-77, a coplanar congener, showed no effect. Our second study using a mouse model that was deficient in the p50 subunit of NF-kB (p50-/-) showed that NF-kB contributes to the changes in hepatocyte proliferation and apoptosis in response to PCB-153 treatment: a single dose of PCB-153 increased hepatic …

The Extent Of Protection Of The Individual’S Personality Against Commercial Use: Toward A New Property Right, George P. Smith Ii Jan 2002

The Extent Of Protection Of The Individual’S Personality Against Commercial Use: Toward A New Property Right, George P. Smith Ii

Scholarly Articles

The purpose of this Article is to explore the extent of an individual's right of privacy, vis-à-vis the concepts of commercial use and appropriations, which compromise rights of publicity. The deceptively simple, yet complex, conclusion to be drawn from this analysis is that a delicate balance of interests must be struck, either legislatively or judicially, between recognizing a full right of privacy, and its permutations in the right of publicity, with the press and news media. A definitive balancing test may be elusive, but at a minimum, a framework for principled decision making must be attempted. It is imperative that …

The Science, Law, And Politics Of Fetal Pain Legislation, Kevin C. Walsh Jan 2002

The Science, Law, And Politics Of Fetal Pain Legislation, Kevin C. Walsh

Scholarly Articles

Most people prefer not to inflict gratuitous pain on other sentient beings, especially other humans. What, then, should be the legal system's reaction to the mounting evidence that in late-term abortions doctors are inflicting just such pain on fetuses who have the anatomical, physiological, and neurological capacity to experience it? The pain being inflicted is gratuitous because it can be easily avoided with no significant increases in cost or health risk by the administration of tar geted fetal pain relief. If informed that an abortion is likely to cause pain to the fetus and given a choice between a procedure …

Type-Specific Inositol 1,4,5-Trisphosphate Receptor Localization In The Vomeronasal Organ And Its Interaction With A Transient Receptor Potential Channel, Trpc2, Jessica H. Brann, John C. Dennis, Edward E. Morrison, Debra A. Fadool

Biology: Faculty Publications and Other Works

The vomeronasal organ (VNO) is the receptor portion of the accessory olfactory system and transduces chemical cues that identify social hierarchy, reproductive status, conspecifics and prey. Signal transduction in VNO neurons is apparently accomplished via an inositol 1,4,5-trisphosphate (IP3)-activated calcium conductance that includes a different set of G proteins than those identified in vertebrate olfactory sensory neurons. We used immunohistochemical (IHC) and SDS-PAGE/western analysis to localize three IP3 receptors (IP3R) in the rat VNO epithelium. Type-I IP3R expression was weak or absent. Antisera for type-II and -III IP3R recognized appropriate molecular weight proteins by SDS-PAGE, and labeled protein could be …

Wolves In Utah: An Analysis Of Potential Impacts And Recommendations For Management, T. Adam Switalski, Trey Simmons, Shiree L. Duncan, Andreas S. Chavez, Robert H. Schmidt Jan 2002

Wolves In Utah: An Analysis Of Potential Impacts And Recommendations For Management, T. Adam Switalski, Trey Simmons, Shiree L. Duncan, Andreas S. Chavez, Robert H. Schmidt

Natural Resources and Environmental Issues

The historic range of gray wolves (Canis lupus) in Utah was essentially statewide. Although their presence cannot be disputed, the historic abundance of wolves in Utah is unknown. The release of gray wolves into Yellowstone National Park and central Idaho in 1995 established growing populations, and increasing dispersal is bringing these wolves closer to Utah. It seems likely that wolves will commingle with Utah's other native mammals in the near future. The potential presence of wolves in Utah is generating a series of questions and debates. In this report, we review the potential of wolves in Utah and make predictions …

The Influence Of Surfactants On The Sorption Of Phenanthrene In Natural Waters, Tracey Louise Jones-Hughes Jan 2002

The Influence Of Surfactants On The Sorption Of Phenanthrene In Natural Waters, Tracey Louise Jones-Hughes

School of Geography, Earth and Environmental Sciences Theses

Polycyclic aromatic hydrocarbons (PAHs) are widely recognised as harmful, persistent organic pollutants, whilst surfactants are more easily degraded but their ubiquitous use both domestically and industrially ensures their presence in natural waters. Owing to both their hydrophobic and hydrophilic properties, surfactants are capable of both adsolubilisation and solubilisation of co-contaminants, hence, their presence in natural waters is considered extremely significant. The purpose of this research was to determine how surfactants and PAHs influence each other in estuaries where both are co-disposed. This study is the first to employ environmentally realistic concentrations of surfactants and to use natural particles in order …

Unresolved Complex Mixtures Of Aromatic Hydrocarbons In The Marine Environment : Toxicity, Solubility And Photodegradation Studies, Emma Louise Smith Jan 2002

Unresolved Complex Mixtures Of Aromatic Hydrocarbons In The Marine Environment : Toxicity, Solubility And Photodegradation Studies, Emma Louise Smith

School of Geography, Earth and Environmental Sciences Theses

Unresolved complex mixtures (UCMs) of aromatic hydrocarbons have been found in a wide range of environmental matrices at high concentrations. However, limited consideration has been given to the potential detrimental effects of the accumulation of these compounds in the marine environment. In particular, there is a need to evaluate these compounds in the light of recent evidence that points to the long term effects of oil in the marine environment. The overall aim of this work was therefore to investigate unresolved complex mixtures of aromatic hydrocarbons in the marine environment with particular emphasis on assessment of toxicity, aqueous solubility and …

Barriers To Sustainability Among Tourism-Related Businesses : Identification And Reduction, Jonathan Andrew Vernon Jan 2002

Barriers To Sustainability Among Tourism-Related Businesses : Identification And Reduction, Jonathan Andrew Vernon

School of Geography, Earth and Environmental Sciences Theses

The attainment of sustainable development has emerged as one of the main challenges facing society and the economy in the twenty-first century. In tourism, the English Tourism Council (2001 a, p. 11) recognise that sustainable tourism can no longer be regarded as an optional extra, but is fundamental to safeguarding the long-term competitiveness of the industry. To establish sustainable development as a primary strategic objective within the tourism industry represents a substantial challenge. Such a goal is problematic not least because the sector is so diverse and is based around a large number of small businesses which are not always …

Captive Dolphins, Tursiops Truncatus, Develop Signature Whistles That Match Acoustic Features Of Human-Made Model Sounds, Jennifer L. Miksis, Peter L. Tyack, John R. Buck

Graduate School of Oceanography Faculty Publications

This paper presents a cross-sectional study testing whether dolphins that are born in aquarium pools where they hear trainers’ whistles develop whistles that are less frequency modulated than those of wild dolphins. Ten pairs of captive and wild dolphins were matched for age and sex. Twenty whistles were sampled from each dolphin. Several traditional acoustic features (total duration, duration minus any silent periods, etc.) were measured for each whistle, in addition to newly defined flatness parameters: total flatness ratio (percentage of whistle scored as unmodulated), and contiguous flatness ratio (duration of longest flat segment divided by total duration). The durations …

A Method For The Perceptual Optimization Of Complex Visualizations, Donald H. House, Colin Ware Jan 2002

A Method For The Perceptual Optimization Of Complex Visualizations, Donald H. House, Colin Ware

Center for Coastal and Ocean Mapping

A common problem in visualization applications is the display of one surface overlying another. Unfortunately, it is extremely difficult to do this clearly and effectively. Stereoscopic viewing can help, but in order for us to be able to see both surfaces simultaneously, they must be textured, and the top surface must be made partially transparent. There is also abundant evidence that all textures are not equal in helping to reveal surface shape, but there are no general guidelines describing the best set of textures to be used in this way. What makes the problem difficult to perceptually optimize is that …

The Role Of Cellular Stress During Cold Ischaemic And Reperfusion Injury, Jonathan Richard Roberts Jan 2002

The Role Of Cellular Stress During Cold Ischaemic And Reperfusion Injury, Jonathan Richard Roberts

Peninsula Medical School Theses

The elemental physiology of the highly complex and regulated cellular response to stress remains poorly understood. Hypothermia and reperfusion are necessary and unavoidable stresses associated with the procurement, storage and transplantation of organs such as the kidney. Signal transduction pathways and transcription factors are evolutionarily conserved mediators of stress responses. This project has investigated the activation of the transcription factors Nuclear Factor kappa B (NFκB), Activator Protein 1 (AP1) and the Heat Shock Factor I (HSF1) as well as the mitogen activated protein kinases (MAPK), p38, JNK and ERK 1 /2, during hypothermic and reperfusion stress in cultured endothelial cells …

Multibeam Volume Acoustic Backscatter Imagery And Reverberation Measurements In The Northeastern Gulf Of Mexico, Timoth C. Gallaudet, Christian De Moustier Jan 2002

Multibeam Volume Acoustic Backscatter Imagery And Reverberation Measurements In The Northeastern Gulf Of Mexico, Timoth C. Gallaudet, Christian De Moustier

Center for Coastal and Ocean Mapping

Multibeam volume acoustic backscatterimagery and reverberation measurements are derived from data collected in 200-m-deep waters in the northeastern Gulf of Mexico, with the Toroidal Volume Search Sonar (TVSS), a 68-kHz cylindrical sonar operated by the U.S. Navy’s Coastal System Station. The TVSS’s 360-degree vertical imaging plane allows simultaneous identification of multiple volume scattering sources and their discrimination from backscatter at the sea surface or the seafloor. This imaging capability is used to construct a three-dimensional representation of a pelagic fish school near the bottom. Scattering layers imaged in the mixed layer and upper thermocline are attributed to assemblages of epipelagic …

Marine Science Faculty Publications

During March/April 1998 we conducted detailed mapping and sampling of hydrothermal plumes along six segments of Earth's fasting spreading mid-ocean ridge, 27.5°–32.3°S on the East Pacific Rise. We compared the distribution and chemistry of hydrothermal plumes to geological indicators of long-term (spreading rate) and moderate-term (ridge inflation) variations in magmatic budget. In this large-offset, propagating rift setting, these geological indices span virtually the entire range found along fast spreading ridges worldwide. Hydrothermal plumes overlaid ∼60% of the length of superfast (>130 km/Myr) spreading axis surveyed and defined at least 14 separate vent fields. We observed no plumes over the …

Genetic Analysis Of The Microvascular Complications Of Diabetes Mellitus, Deborah F Cross Jan 2002

Genetic Analysis Of The Microvascular Complications Of Diabetes Mellitus, Deborah F Cross

Other Faculty of Health Theses

There is increasing evidence to suggest that genetic factors are involved in the pathogenesis of microvascular complications in diabetes mellitus. Recent studies have suggested that genetic variations in the aldose reductase (ALR2) gene may contribute to the genetic susceptibility to microvascular complications. Aldose reductase is the first and rate-limiting enzyme of the polyol pathway and is implicated in the pathogenesis of diabetic microvascular disease (nephropathy, retinopathy and neuropathy). It has recently been shown that the three polymorphisms of the ALR2 gene are associated with susceptibility to microvascular complications in both TIDM and T2DM. The aim of this study was to …
