The Effects Of Thymic Hormones On The Proliferation Of Human Myelogenous Leukemia Cells, Melissa Pompilius

UNLV Retrospective Theses & Dissertations

Thymosin fraction 5 (TF5), comprised of an array of small molecular weight peptides, partially purified from the adult bovine thymus gland, contains multiple biologically active humoral factors. TF5 influences T cell differentiation, lymphokine production and restores immune deficiencies in a variety of animal models in vitro and in vivo. Because TF5 generally enhances immune reactivity, we examined the effects of TF5 on the proliferation of HL-60 human promyelocytic leukemia cells. Direct viable dye cell counting, the MTT reaction, and the clonogenic potential of HL-60 cells were used to determine cell proliferation. The potency and efficacy of TF5 for the inhibition …

Alternative Perspectives Of Projectile Point Variability During The Levantine Neolithic, Doss F. Powell

UNLV Retrospective Theses & Dissertations

Ghwair I, a Pre-Pottery Neolithic B community in southern Jordan, has an abundant projectile point assemblage that facilitates a thorough characterization and detailed techno-typological analysis of the projectile points recovered. It is concluded that current typologies tend to mask significant morphological aspects of the projectile points. To explore these aspects, other perspectives such as raw material selection and manufacture are considered; The low amounts of cortex, minimum retouch, and the frequency tertiary blades are shown to be reflections of a conscientious effort to secure fine quality chert for lithic production. The presence of the "miniature" points represents a deliberate effort …

The Acute Effects Of Transdermal Testosterone Precursor Administration On Serum Steroid Hormone Levels In Females, Mark Anthony Rasmussen

UNLV Retrospective Theses & Dissertations

Most governing sports authorities have banned the use of anabolic steroids as ergogenic aids. Recently, a transdermal testosterone precursor dietary supplement (AndrosteDERMRTM) has become available; athletes can apply the cream to their skin with the belief that it will increase serum testosterone levels, muscle mass, and strength. The purpose of this study was to measure the effects of one milliliter of AndrosteDERMRTM) applied to the inner surface of the upper arm on the serum levels of androstenedione, and free and total testosterone in female subjects. Serum levels were measured before application and every 45 minutes thereafter for six hours. Serum …

Craniofacial Morphology And The Consequences Of Intentional Cranial Deformation Among Prehistoric Andean Populations, Matthew Paul Rhode

UNLV Retrospective Theses & Dissertations

This research examined the cultural practice of cranial deformation (annular and anteroposterior), and its effects on 27 craniometric measurements and biodistances among 350 prehistoric crania from the Azapa valley of northern Chile. Included among these 27 measurements were nine facial measurements previously considered to be unaffected by deformation. One-way ANOVA, Bonferroni multiple comparisons, and discriminant function analyses indicated that out of the 27 measurements were seven centrally located facial and basilar measurements unaffected by deformation: orbital breadth, palate (maxillo-alveolar) breadth, nasal breadth, basion-prosthion length, cranial base length, foramen magnum length, and foramen magnum breath. Included among these seven measurements were …

Sedentism Among The Archaic Fisher-Folk Of Northern Chile: A Malacological Perspective, Sally D Llull-Billings

UNLV Retrospective Theses & Dissertations

Oxygen isotope analysis of shell material from the Camarones West Shell Midden and from the site of Quiani has revealed that year-round collection of shellfish for food by the people of the Chinchorro Culture was not practiced. Additional shell demographics from the site of Quiani further support the oxygen isotope results. Radiocarbon dating revealed that the midden sample spanned the Classic Chinchorro and Transitional Chinchorro epochs, from 5590 to 3830 B. P. Shell classification and quantification of these sites also revealed that shellfish collection and the types of shellfish harvested has been consistent from Chinchorro times to the present; This …

Increasing Parental Knowledge In Treatment Of Childhood Fever, Brian D Bishop

UNLV Retrospective Theses & Dissertations

Fever is the single most common symptom that causes parents to seek medical attention for their young children (Kramer, Naimark, & Leduc, 1985). Parental lack of knowledge regarding the management of pediatric fever plays a roll in this phenomenon. The problem addressed in this study is inappropriate parental usage of emergency treatment resources for the treatment of non-emergent childhood fevers. This study tested if providing direct and indirect information about childhood fever and its treatment resulted in a decrease of inappropriate emergency room visits for non-emergent pediatric febrile illnesses for a select population; A quasi-experimental design was used with a …

Estimating Effective Discharge At Lehman Creek, Great Basin National Park, Nevada, Lisa A Glonek

UNLV Retrospective Theses & Dissertations

Effective discharge is defined as the streamflow that transports the most sediment over time and is therefore the flow that controls channel shape. Effective discharge was estimated for two sites along Lehman Creek, an alpine fluvial system. Site one (WL-1, 2951 m elevation) has an effective discharge of 0.083 m3/s and site two (WL-2, 2019 m elevation) has an effective discharge of 0.400 m3/s. Calculated bankfull discharges are 2.52 m3/s for WL-1 and 1.48 m3/s for WL-2. Bankfull/effective discharge ratios (b/e ratio) are 30.49 for WL-1 and 3.71 for WL-2. The b/e ratio difference may be due to the steeper …

Precipitating And Prophylactic Factors Contributing To Posttraumatic Stress Disorder Symptomatology In Maltreated Children, Lisa Marie Linning

UNLV Retrospective Theses & Dissertations

This study examined mediating factors that lead to, or buffer against, development of posttraumatic stress disorder (PTSD) after child maltreatment. Fifty-five children aged 8--17 years voluntarily completed self-report questionnaires and a structured diagnostic interview. It was hypothesized that (1) chronicity and severity of abuse amplify PTSD risk when a child has limited support networks, ineffective coping, external locus of control, affect dysregulation, and a dysfunctional family; (2) key family and victim characteristics would help to ameliorate effects of traumatic abuse; (3) the combination of precipitating and prophylactic factors would determine the effectiveness of managing traumatic maltreatment. Results suggest that dysthymia, …

The Effects Of Static Stretching Sets In Warm-Up On Maximum Vertical Jump Performance, David R Pestana

UNLV Retrospective Theses & Dissertations

The purpose of the study was to determine whether changing the number of static stretching sets during the warm-up changes maximum vertical jump (MVJ) performance. Twenty-five healthy male and female subjects between the ages of 18--40 volunteered to be in the study. The data was statistically treated using a two (pre-test, post-test) by three (NS, 1SS, and 3SS) ANOVA with repeated measures. The dependent variable was MVJ. The independent variables were test and static stretching sets. The analysis revealed that there were no significant differences between pre-test MVJ scores, but a significant difference between post-test scores for all treatments. MVJ …

Burnt Rock Mound (26ck3601): Late Archaic And Ceramic Period Human Use Of A Northern Mojave Spring Mound, Hal Boyle Rager

UNLV Retrospective Theses & Dissertations

Archaeological excavations and geological trenching at Burnt Rock Spring Mound, 26CK3601, in the northern Mojave Desert has revealed a complex relationship between paleohydrogeology and the prehistoric human use of the site. Multiple formation, accumulation, and deflation episodes since the Late Pleistocene and Holocene correlate with regional climatic models. The mound is located on the northwest periphery of the known extent of Ancestral Puebloan and Patayan peoples. Artifacts, especially micro-debitage, recovered from Late Holocene mound deposits suggest long-term use of this vital resource by Late Archaic and Ceramic peoples.

Teens Understanding Of The Indicators Of The Tendency To Abuse Alcohol: Focus Group Discussions, Bob Van Drimmelen

UNLV Retrospective Theses & Dissertations

Alcohol abuse has become an epidemic in the modern world. The increase in this social problem has brought with it many consequences which everyone in society has to deal with. Unfortunately, the anguish of abuse has also spread through the world of teens. Are there indicators which portend the tendency for teens to abuse alcohol? Quantified research has revealed several of those indicators. Are we helping teens understand what those indicators are? Are teens accepting and learning about those indicators that they might be protected from the harsh consequences? This study begins to help society understand that efforts are being …

The Effects Of Motor Practice On Coarticulatory Interactions In The Speech Of Children And Adults, Kimberly Marie Wieberg

UNLV Retrospective Theses & Dissertations

The current study was designed to elucidate the role of practice on speech production. Specifically, this investigation examined the effects of a distributed practice schedule on speech productions in young children and adults. Unlike the practice period used in previous studies, the practice session utilized in this investigation was spread out over one week (distributed over time), in which participants were required to practice on three different occasions before being retested. Therefore, the purpose of this investigation is to examine the notion of a developmental trend of coarticulation in children by verifying whether or not speech production strategies as exhibited …

Excavation And Interpretation: 42ws126, The Watchman Site, Zion National Park, Utah, Suzanne Beryl Eskenazi

UNLV Retrospective Theses & Dissertations

Excavations at 42Ws126, a Virgin Anasazi site in Zion National Park, Utah, were conducted for three weeks in the summer of 2000 by archaeologists from the Desert Research Institute in Las Vegas, Nevada, along with high school students and teachers from Nevada and southern Utah as part of a public outreach program. The site consists of aboveground and subsurface storage units and hearth features; no evidence for habitation was encountered. The architecture, ceramic, lithic, and ground stone assemblages indicate small-scale, short-term use of the site. Radiocarbon dates from charred material, the presence of both early and later ceramic types, and …

Protoporphyrin Ix Distribution In Rat Brain Following The Administration Of 5-Aminolevulinic Acid And Its Hexylester, Scott Alan Friesen

UNLV Retrospective Theses & Dissertations

Rowett nude rats were injected intra-cranially with varying concentrations of 5-aminolevulinic acid (10, 20, 99, 199, 398 mM) and its hexylester (6.6, 13, 66, 132, 265 mM). Toxicity effects of these compounds were examined based on animal behavior and respiratory distress. It was determined that the maximum tolerable dose for intra-cranial injection is 99 mM 5-Aminolevulinic acid and 66 mM h-ALA; Human glioma spheroids were grown in vitro. After incubation, spheroids were sized (250--350 mum) and injected into the rat brain (10 spheroids per injection). Following the induction and development of glioblastoma multiforme tumors in vivo, Rowett nude rats were …

Complexity: Theoretical And Methodological Applications For Sociology, Kathryn A Gilpatric

UNLV Retrospective Theses & Dissertations

This thesis examines the usefulness of Complexity as a new tool for sociology. Complexity, as its own branch of study, developed from the new science of Chaos. Recent paradigmatic disputes occurring in the scientific community have been the force of a growing sense of change in the way many different disciplines view complex systems. Since it is evident that social systems are typically highly complex, it makes sense that a scientific paradigm, which investigates the nature of complex systems, should also be applicable to social systems. Science now argues that the old Newtonian clockwork mentalities and classical experimental models cannot …

Characterization Of The Pleiotropic Effects Of The Drosophila Gene Mushroom Body Miniature B, Michael Louis Ginsburg

UNLV Retrospective Theses & Dissertations

The mushroom body miniature B ( mbmB) mutation has documented defects in adult mushroom body anatomy, olfactory memory and female fertility. In this thesis I report that mbmB mutants also have reduced viability and growth rate. I further demonstrate, using the mushroom body cell marker dachshund, that loss of mbmB function does not affect the early development of mushroom body neuroectoderm and neuroblasts. Additionally, I found the observed delay in growth and reduced viability were not manifested during embryonic development; Courtship behavior assays and immunohistochemical techniques were used to investigate causes of mbmB female sterility. Courtship involving mbmB females is …

Teaching The Origins Controversy: Science, Or Religion, Or Speech?, David K. Dewolf, Stephen C. Meyer, Mark Edward Deforrest

Utah Law Review

One can hardly imagine a more contentious issue in the American culture wars than the debate over how biological origins should be taught in the public schools. On the one hand, the National Academy of Sciences, the National Center for Science Education, and the American Civil Liberties Union have insisted that any departure from a strictly Darwinian approach to the issue constitutes an attack on science itself, and even an unconstitutional intrusion of religion into the public school science curriculum. On the other hand, many parents and religious activists have long rebelled against what they perceive as a dogmatic attack …

A Comparative Study Of The Feeding Ecology Of Chelonia Mydas (Green Turtle) And The Incidental Ingestion Of Prorocentrum Spp, Karen Gayle Holloway Adkins

Retrospective Theses and Dissertations

The diets of green turtles from five dissimilar aggregations of juvenile C. mydas on the East Coast of Florida were analyzed. C. mydas were captured by tangle net from four of the study sites and a dietary sample was collected by an esophageal flushing technique. The gut content of stranded individuals was collected for the fifth site. The vegetation in these study areas differs in varying degrees of abundance and diversity. Analysis of the samples revealed the alga types preferred by green turtles from each population and provided the basis for examination of similarities and differences in their diets.
