The Genus Auyantepuia González-Sponga, 1978 Is Confirmed As A Synonym Of Broteochactas Pocock, 1893 (Scorpiones: Chactidae), Michael E. Soleglad, Victor Fet

Euscorpius

The genus Auyantepuia González-Sponga, 1978 is confirmed as a synonym of Broteochactas Pocock, 1893 (Scorpiones: Chactidae). It was correctly synonymized with Broteochactas by Francke & Boos (1986) and listed as such by Soleglad & Fet (2003) but resurrected by Lourenço & Araújo (2004). We reconfirm that the generic name Auyantepuia, based on the type species Broteochactas scorzai Dagert, 1957 from Venezuela, is a synonym of Broteochactas, based on the type species Broteochactas nitidus Pocock, 1893 from Trinidad. All other seven “short-fingered” species from French Guiana and Brazil, classified by Lourenço & Araújo (2004) under Auyantepuia, belong to …

Correlations Between Quantitative Fat–Water Magnetic Resonance Imaging And Computed Tomography In Human Subcutaneous White Adipose Tissue, Aliya Gifford, Ronald C. Walker, Theodore F. Towse, E Brian Welch Dec 2015

Correlations Between Quantitative Fat–Water Magnetic Resonance Imaging And Computed Tomography In Human Subcutaneous White Adipose Tissue, Aliya Gifford, Ronald C. Walker, Theodore F. Towse, E Brian Welch

Peer Reviewed Articles

Beyond estimation of depot volumes, quantitative analysis of adipose tissue properties could improve understanding of how adipose tissue correlates with metabolic risk factors. We investigated whether the fat signal fraction (FSF) derived from quantitative fat–water magnetic resonance imaging (MRI) scans at 3.0 T correlates to CT Hounsfield units (HU) of the same tissue. These measures were acquired in the subcutaneous white adipose tissue (WAT) at the umbilical level of 21 healthy adult subjects. A moderate correlation exists between MRI- and CT-derived WAT values for all subjects, R2=0.54, p<0.0001, with a slope of −2.6, (95% CI [−3.3,−1.8]), indicating that a decrease of 1 HU equals a mean increase of 0.38% FSF. We demonstrate that FSF estimates obtained using quantitative fat–water MRI techniques correlate with CT HU values in subcutaneous WAT, and therefore, MRI-based FSF could be used as an alternative to CT HU for assessing metabolic risk factors.

Transformational Learning: An Investigation Of The Emotional Maturation Advancement In Learners Aged 50 And Older, Susan Lorraine Lundry

Dissertations

Human beings have spent much time and effort in trying to understand themselves, others, and their world. Mankind uses intellect when trying to understand life but the majority of people continue to encounter frustration, confusion, and a variety of obstacles when dealing with daily challenges and people. Theorists and researchers understand that successful existence requires more than mere knowledge; it requires a level of understanding, a form of wisdom foreign to the bulk of the populace. The missing ingredient for this kind of wisdom is the ability to ‘know thyself,’ which is the beginning of establishing a higher level of …

On 23 July 2013, a marine gas rig (Hercules 265) ignited in the northern Gulf of Mexico. The rig burned out of control for 2 days before being extinguished. We conducted a rapid‐response sampling campaign near Hercules 265 after the fire to ascertain if sediments and fishes were polluted above earlier baseline levels. A surface drifter study confirmed that surface ocean water flowed to the southeast of the Hercules site, while the atmospheric plume generated by the blowout was in eastward direction. Sediment cores were collected to the SE of the rig at a distance of ∼0.2, 8, …

The Role Of A Psychiatric Mental Health Nurse Practitioner As Part Of A Mobile Health Unit For The Homeless Population, Joan Alviar Fraino

Doctor of Nursing Practice (DNP) Projects

An estimated 2.3 to 3.5 million people are homeless in the U.S., often living with chronic medical and mental illnesses. The underserved population, such as the homeless, continues to experience gaps in services, resulting in poor healthcare outcomes and readmission to the hospital setting. They often present in crisis through the emergency room, contributing to an already overburdened healthcare system. Increased spending and overutilization of healthcare services continues to rise in the United States (U.S.). Due in part to advancements in technology and expanded health insurance coverage, American healthcare continues be one of the most expensive commodities in the U.S. …


Monitoring Biodiversity Of San Francisco Peninsula Grasslands Using Lepidoptera As A Bioindicator, Jonathan B. Sifuentes-Winter Dec 2015

Monitoring Biodiversity Of San Francisco Peninsula Grasslands Using Lepidoptera As A Bioindicator, Jonathan B. Sifuentes-Winter

Master's Projects and Capstones

San Francisco Peninsula grasslands have seen an influx of non-native invasive species starting in the 1500’s, threatening ecological stability by reducing biological diversity. To combat these invasive species, multiple public agencies have begun to adopt an integrated pest management (IPM) approach. This ecologically-based approach to pest management utilizes three controversial techniques, which are presently used or are under consideration for use on the San Francisco Peninsula: herbicide application, conservation grazing, and prescribed fire. In this paper, I will evaluate the use of the taxa Lepidoptera as a bioindicator of biodiversity to assess the environmental impacts of these techniques. The application …

Amyloid Proteins Structure, Dynamics, Interactions And Early Stages Of Self-Assembly, Yuliang Zhang Dec 2015

Amyloid Proteins Structure, Dynamics, Interactions And Early Stages Of Self-Assembly, Yuliang Zhang

Theses & Dissertations

The self-assembly and aggregation of amyloid protein are associated with several neurodegenerative diseases. The evidence indicates that the oligomeric intermediates, formed prior to the final fibrillary product, are the primary culprits of neurotoxicity. Although tremendous efforts have been dedicated for the characterization of structures, dynamics and toxic-related hallmarks of the oligomers, to date, yet the mechanism of such assembly from disordered monomers and their structure remain elusive.

In this dissertation, I focused on understanding the dimerization process of amyloid proteins and peptides of different sizes and I combined experimental studies with high-power computer simulations. The AFM force spectroscopy experiments showed …


Biodegradable Hybrid Nanogels For Combination Chemotherapy, Swapnil Desale Dec 2015

Biodegradable Hybrid Nanogels For Combination Chemotherapy, Swapnil Desale

Theses & Dissertations

Combination chemotherapy is commonly used to treat cancer, because such a therapy regimens usually involve sequential administration of multiple drugs and allow targeting different cell signaling pathway. The co-delivery of drug combination at a controlled ratio via the same vehicle is offering the advantages such as spatial-temporal synchronization of drug exposure, synergistic therapeutic effects and suppression of drug resistance. Undoubtedly, there are several molecular and pharmacological factors that determine the effectiveness of drug combinations. A rationally designed drug combination is required since certain drug ratios and the definitive exposure to the targets of interest can only be synergistic while others …

Development Of Manganese-Enhanced Magnetic Resonance Imaging (Memri) Methods To Study Pathophysiology Underlying Neurodegenerative Diseases In Murine Models, Aditya N. Bade

Theses & Dissertations

Manganese-enhanced magnetic resonance imaging (MEMRI) opens the great opportunity to study complex paradigms of central nervous system (CNS) in freely behaving animals and reveals new pathophysiological information that might be otherwise difficult to gain. Due to advantageous chemical and biological properties of manganese (Mn2+), MEMRI has been successfully applied in the studies of several neurological diseases using translational animal models to assess comprehensive information about neuronal activity, morphology, neuronal tracts, and rate of axonal transport. Although previous studies highlight the potential of MEMRI for brain imaging, the limitations concerning the use of Mn2+ in living animals and …

Acute Methamphetamine Exposure Affects Histone Modifying Enzymes And Cytokine Production In Macrophages, Ariel Burns Dec 2015

Acute Methamphetamine Exposure Affects Histone Modifying Enzymes And Cytokine Production In Macrophages, Ariel Burns

Theses & Dissertations

The effects of methamphetamine (Meth) in the periphery are not well studied and a comprehensive investigation on the effects and molecular mechanism will give insight into why Meth users are at an increased risk of infections. For this reason, we use macrophages as a model for the immune system dysregulation seen in Meth abusers and also because macrophages are a long-lived cell that HIV infects and persists in. We aimed to determine the effects of Meth on the cytokine production, histone modifying enzymes and the corresponding histone post-translational modifications, and the molecular mechanism in HIV-infected human macrophages treated with combination …


The Effects Of Thc On Attentional Bias To Emotional Stimuli, Sydney N. Haberberger Dec 2015

The Effects Of Thc On Attentional Bias To Emotional Stimuli, Sydney N. Haberberger

Honors Theses

The current study tested the hypothesis that the effects of THC on affect are mediated by the ability of THC to alter attentional bias to positive and negative stimuli. The study was completed by 16 participants, all of whom were consistent marijuana users. During sessions, participants used a machine called a Quantified Smoke Delivery System, which delivers a controlled amount of smoke to the user, to smoke either a cigarette that contained THC or a placebo cigarette. After smoking, participants would complete a task. During tasks, participants were placed in an eye tracking apparatus in order to record the movement …

A Novel Transcription Factor In Arabidopsis Thaliana Abiotic Stress Response, Achira S. Weerathunga Arachchilage Dec 2015

A Novel Transcription Factor In Arabidopsis Thaliana Abiotic Stress Response, Achira S. Weerathunga Arachchilage

LSU New Orleans Theses and Dissertations

Plants respond to environmental stress by altering their gene expression. Under stress conditions some genes are activated and some genes are repressed. Even though a lot of work has been done to understand mechanisms of gene activation under abiotic stress very little information is available on how stress responsive genes are kept repressed under normal growth conditions. Recent work has revealed that plants use transcriptional repression as common mechanism of gene repression. Transcriptional repression is achieved by recruitment co-repressor complexes to the target genes. Recent studies have revealed that the co-repressor LUH complexes with SLK1 and SLK2 to silence Arabidopsis …

Response Of Fishes To Restoration Projects In Bayou St. John Located Within The City Of New Orleans, Louisiana, Including Hydrological Characterization And Hydrodynamic Modelling, Patrick W. Smith

LSU New Orleans Theses and Dissertations

Quantifying the impacts of restoration on coastal waterways is crucial to understanding their effectiveness. Here, I look at the impacts of multiple restoration projects on urban waterways within the city limits of New Orleans, LA, with an emphasis on the response of fishes. First I report the effects of two projects designed to improve exchange down estuary on the hydrologic characteristics of Bayou St. John (BSJ). Within BSJ, flow is dominated by subtidal wind driven processes. Removal of an outdated flood control structure did not appear to alter exchange in BSJ, but removal combined with sector gate openings did. I …
