Lanthanide Complexes As Fluorescent Indicators For Neutral Sugars And Cancer Biomarkers, Onur Alpturk

LSU Doctoral Dissertations

Simple water soluble lanthanum and europium complexes are effective at detecting neutral sugars as well as glyco- and phospholipids. In solutions at physiologically relevant pH the fluorescent lanthanum complex binds neutral sugars with apparent binding constants comparable to those of arylboronic acids. Interference from commonly occurring anions is minimal. The europium complex detects sialic acid-containing gangliosides at pH 7.0 over an asialoganglioside. This selectivity is attributed, in large part, to the cooperative complexation of the oligosaccharide and sialic acid residues to the metal center, based on analogous prior studies. In MeOH, lysophosphatidic acid (LPA), a biomarker for several pathological conditions …

The temperatures 150oC and 175oC were used for the oxidation study and a 60oC was used for incubation storage. The methanol extracts of all four spices demonstrated significant capability in retaining the DHA and EPA, after subjected to oxidation when compared …

Using Power Spectra To Look For Anisotropies In Ultra-High Energy Cosmic Ray Distributions, Megan Alicia Mcewen

LSU Doctoral Dissertations

The origins and compositions of ultra-high energy cosmic rays (UHECR) remains a mystery to this day. The Pierre Auger Observatory (PAO) is being constructed now in the hopes that it will help solve this mystery by detecting more UHECR than any previous experiment. In this dissertation, I will discuss this experiment, and analyze the data collected so far by comparing it with simulated data from possible source distributions. In these simulations, I will track antiprotons, along with other possible cosmic ray primaries, through various models of galactic and extragalactic magnetic fields. Once they reach a certain distance, I will record …

Exploring The Ligand Binding Site On The Dopamine Transporter By Photoaffinity Labeling And Site-Directed Mutagenesis, Maria Laura Parnas

Theses and Dissertations

The dopamine transporter (DAT) is a neuronal presynaptic transmembrane protein that clears released dopamine (DA) from the synaptic space, regulating the neurotransmitter concentration and availability, DAT and the related serotonin (SERT) and norepinephrine (NET) transporters belong to the SLC6 family of Na+ and CI- dependent symporters, and are major targets for the action of several drugs, including the psychostimulant cocaine. DAT is predicted to possess 12 transmembrane spanning domains (TMs), with both N- and C-termini located intracellularly. Extensive research efforts to gain insight on the molecular aspects of DAT have been attempted, but the three-dimensional arrangement of the protein as …

Instead Of Erklären And Verstehen: William James On Human Understanding, David E. Leary

Psychology Faculty Publications

Perhaps more than any other American psychologist and philosopher, William James (1842-1910) was intimately familiar with contemporary European thought and debate, including the discussion of Erklären and Verstehen advanced by Wilhelm Dilthey (1833-1911) and others around the turn of the twentieth century. Even before this discussion was initiated, James had been dealing with related issues, pondering alternative solutions, and formulating his own original views on human understanding. These views coalesced in a distinctive approach to cognition. Fundamental to this approach was a belief in possibility and probability as innate features of the physical as well as mental manifestations of the …

Age-Appropriate Programs: Best Practice: Effective Programs Are Designed To Match The Developmental Stages Of The Learner, Daphne Sewing, Allison Brody

Education about the Environment

Children and adults learn in completely different ways. Too often, however, children’s programs are developed from an adult’s perspective, rather than that of a child. The best children’s environmental education programs are designed with children’s abilities, developmental needs, interests, and learning styles in mind. Different programs should be created to appropriately meet the needs of different age groups and their respective cognitive development, attention spans, coordination abilities, interests, and ways of interacting with nature.

Species Richness And Soil Properties In Pinus Ponderosa Forests: A Structural Equation Modeling Analysis, Daniel C. Laughlin, Scott R. Abella, W. Wallace Covington, James B. Grace

Public Policy and Leadership Faculty Research

Question: How are the effects of mineral soil properties on understory plant species richness propagated through a network of processes involving the forest overstory, soil organic matter, soil nitrogen, and understory plant abundance? Location: North-central Arizona, USA. Methods: We sampled 75 0.05-ha plots across a broad soil gradient in a Pinus ponderosa (ponderosa pine) forest ecosystem. We evaluated multivariate models of plant species richness using structural equation modeling. Results: Richness was highest at intermediate levels of understory plant cover, suggesting that both colonization success and competitive exclusion can limit richness in this system. We did not detect a reciprocal positive …

Past, Present, And Future Old Growth In Frequent-Fire Conifer Forests Of The Western United States, Scott R. Abella, W. Wallace Covington, Peter Z. Fule, Leigh B. Lentile, Andrew J. Sanchez Meador, Penelope Morgan

Public Policy and Leadership Faculty Research

Old growth in the frequent-fire conifer forests of the western United States, such as those containing ponderosa pine (Pinus ponderosa), Jeffrey pine (P. jeffreyi), giant sequoia (Sequioa giganteum) and other species, has undergone major changes since Euro-American settlement. Understanding past changes and anticipating future changes under different potential management scenarios are fundamental to developing ecologically based fuel reduction or ecological restoration treatments. Some of the many changes that have occurred in these forests include shifts from historically frequent surface fire to no fire or to stand-replacing fire regimes, increases in tree density, increased abundance of fire-intolerant trees, decreases in understory …

Forest-Floor Treatments In Arizona Ponderosa Pine Restoration Ecosystems: No Short-Term Effects On Plant Communities, Scott R. Abella, W. Wallace Covington

Public Policy and Leadership Faculty Research

Leaf litter accumulation during fire exclusion and increases in tree density in postsettlement southwestern Pinus ponderosa forests may limit the establishment of understory vegetation. We performed an experiment in P. ponderosa forests of northern Arizona to ascertain plant community responses to forest-floor scarification and Oi removal on thirty-six 100-m2 plots overlaid on an existing ecological restoration experiment that involved tree thinning and prescribed burning. Constrasting with findings from many other forest types, forest-floor treatments had no effect on community diversity or composition during the 2-year experiment. Sørensen similarities were as high as 97% between posttreatment years within treatments; and successional …

Antioxidants And Pain Control In Patients With Chronic Pancreatitis: A Never-Ending Story, Raffaele Pezzilli, Lorenzo Fantini

Turkish Journal of Medical Sciences

Chronic pancreatitis is a benign disease often characterized by recurrent episodes of abdominal pain accompanied by progressive pancreatic exocrine and endocrine insufficiency; it sometimes requires multiple hospitalizations. This disease is frequently the result of chronic alcohol abuse, even if other factors such as genetic alterations, autoimmune disorders, and obstructive disease of the biliary tract and the pancreas may cause the disease. The pain can be considered the most important symptom; it significantly modifies the quality of life of patients with chronic pancreatitis and its control represents a challenge in the treatment of the disease. Among the several modalities for controlling …

Cobalamin Deficiency During Pregnancy Expressed As Elevated Urine Methylmalonic Acid Levels Determined By A Photometric Assay, Osman Meti̇n İpçi̇oğlu, Mustafa Gültepe, Ömer Özcan

Turkish Journal of Medical Sciences

Aim: Deficiency of cobalamin and folate during pregnancy is associated with megaloblastic anemia. Lower levels of folate and vitamin B12 were reported in mothers whose offspring had neural tube defects compared to unaffected controls. Increased methylmalonic acid (MMA) levels are a sensitive indicator of mild vitamin B12 deficiency and elevated homocysteine levels denote vitamin B12 or folate deficiency. We aimed to evaluate cobalamin state in pregnancy by using urine MMA levels determined by an economic spectrophotometric method. Materials and Methods: For this cross-sectional study, plasma total homocysteine (tHcy), serum folate and vitamin B12, and urine MMA levels were measured in …

Long-Arm Splinting For Lateral Epicondylitis: A Case Study, Crystal Wolters

Masters Theses

Lateral epicondylitis is a debilitating condition that has a significantly negative effect on the occupational lives of many people. There appears to be no recognized ideal treatment method for the condition. Long-arm splinting for lateral epicondylitis has not been addressed in the literature. A case study was used to thoroughly describe one participant’s experience with long-arm splinting to treat her lateral epicondylitis. She was interviewed, observed, and measurements were taken of her affected arm’s range of motion and strength. The seven themes which were identified through these methods include a description of how her lateral epicondylitis developed, her description of …

The Acute Effects Of Therapeutic Activities On Heart Rate And Blood Pressure: A Literature Review, Patricia Figueiredo Teles

Masters Theses

This review was initiated to identify the best available evidence on the acute effects of therapeutic activities on heart rate (HR) and blood pressure (BP). The inclusion criteria consisted of studies relevant to the topic that investigated adult subjects. The search covered three major databases using key words related to the topic. Due to the nature of the identified investigations, data were summarized using narrative rather than statistical methodology. A total of 3,447 reports of which 43 met the inclusion criteria were reviewed. There is evidence to suggest that certain therapeutic activities may induce a significant acute increase of HR …

Improved Nitrate Sensing Using Ion Selective Electrodes Based On Urea–Calixarene Ionophores, Benjamin Schazmann, Dermot Diamond

Articles

Urea–calix[4]arenes 1 and 2 were synthesised and incorporated into ISE membranes for assessment as sensors for inorganic anions in water. 1 revealed a strong response to all anions following the Hofmeister selectivity order. For ISEs of 2, the response to a portion of the anion series was suppressed, increasing the margin of selectivity of nitrate over chloride, a common interferant of nitrate in fresh and marine water samples. The performance of ISEs containing 2 was compared to commercially available alkylammonium nitrate ion-exchange salts used for nitrate sensing. Our ISEs performed favourably in terms of sensitivity, linear range and LOD performing …

Determining The Fate And Transport Of The Acrylamide Monomer (Amd) In Soil And Groundwater Systems, Todd James Arrowood

UNLV Retrospective Theses & Dissertations

Acrylamide (AMD) is a known animal and suspected human carcinogen and is used to produce polyacrylamide (PAM), which has been proposed as a technology for seepage control in unlined water delivery canals. Previous studies have not quantified the fate and transport of AMD in soil and groundwater systems. In this study, batch experiments and soil column tests (with and without microbial degradation) were conducted on three materials (control sand, gravelly sand and loam soil) to determine the Kd, retardation factor, the form of the sorption isotherm, and determine microbial degradation rates. Soil core tests from samples collected in canals were …

Safe Village Initiative: A Quasi-Experiment, Evaluating The Impact In West Las Vegas, Timothy Radtke

UNLV Retrospective Theses & Dissertations

Beginning in January of 2007, the "Safe Village Initiative" (SVI) was implemented in West Las Vegas in response to firearm violence. SVI represents an effort of combined resources from criminal justice agencies, social service organizations, local clergy, and citizens to disrupt the cycle of violence that characterizes fatal and non-fatal shootings. The SVI is essentially a deterrence based model aimed to reduce firearm offenses; The current study will analyze SVI from two research questions. The research questions are designed to: (1) assess the qualities of SVI that make it unique from previously implemented "pulling levers" models, and (2) assess the …

The Influence Of Collective Efficacy On Reporting Crime Among College Students, Violet Angelina Colavito

UNLV Retrospective Theses & Dissertations

Colleges and universities often aim to create a sense of community and a neighborhood feel for students. University campuses are designed in ways that reflect the factors of social cohesion measured by Goudriaan, Wittebrood, and Nieuwbeerta (2006). Crime on college campuses is an important social issue. Data from the NCVS suggest that between 1995 and 2002, college students experienced an estimated 400,000 to 530,000 violent crimes each year; yet only about 35% of violent victimizations against college students were reported to the police (Baum 2005, and Hart 2003). Yet, research exploring the effect of social cohesion and collective efficacy on …
