Saudi Medical Journal

OBJECTIVE: To compare the differences between glycosylated and non-glycosylated granulocyte colony-stimulating factor (G-CSF) on mobilizing cell regeneration of bone marrow stem cells and repairing injured myocardium. METHODS: In the acute myocardial ischemia model, 40 Sprague-Dawley rats (8 weeks old, weight 200-250 g) were successfully established with isoproteronol (ISO) and randomly and evenly divided into 4 groups: Group G (injected with glycosylated G-CSF), Group N (non-glycosylated G-CSF), Group C ([control] normal saline for 7 days), and Group M (model). At day 5, all rats were labeled with bromodeoxyuridine (BrdU). At day 28, the proportion of CD34+ cells, myocardial BrdU immunohistochemical stain, …

Protected Areas Reduced Poverty In Costa Rica And Thailand, Kwaw S. Andam, Paul J. Ferraro, Katharine R. E. Sims, Andrew Healy, Margaret B. Holland

Economics Faculty Works

As global efforts to protect ecosystems expand, the socioeconomic impact of protected areas on neighboring human communities continues to be a source of intense debate. The debate persists because previous studies do not directly measure socioeconomic outcomes and do not use appropriate comparison groups to account for potential confounders. We illustrate an approach using comprehensive national datasets and quasi-experimental matching methods. We estimate impacts of protected area systems on poverty in Costa Rica and Thailand and find that although communities near protected areas are indeed substantially poorer than national averages, an analysis based on comparison with appropriate controls does not …

Thrombin And Exercise Similarly Influence Expression Of Cell Cycle Genes In Cultured Putative Endothelial Progenitor Cells, Michael M. Lockard, Sarah Witkowski, Nathan T. Jenkins, Espen E. Spangenburg, Thomas O. Obisesan, James M. Hagberg

Exercise and Sport Studies: Faculty Publications

Acute exercise and exercise training may influence putative endothelial progenitor cell (EPC) number and colony forming units (CFU-ECs), although the mechanisms remain unclear. This study examined the effects of in vitro thrombin supplementation and acute exercise on CFU-EC gene expression, associated with cellular proliferation and differentiation. The effect of habitual physical activity was evaluated through analysis of EPCs from chronically high- and low-active men. Participants were healthy high- and low-active men (n = 23), aged 55-80 yr. Circulating CD34+/VEGFR2+ number, CFU-ECs, plasma prothrombin fragment (F1+2), and thrombin-antithrombin III were measured at rest and after 30 min of exercise. Gene expression …

Real-Time Visualizations Of Ocean Data Collected By The Norus Glider, Daniel M. Medina

Master's Theses

Scientific visualization computer applications generate visual representations of large and complex sets of science data. These types of applications allow scientists to gain greater knowledge and insight into their data. For example, the visualization of environmental data is of particular interest to biologists when trying to understand how complex variables interact. Modern robotics and sensors have expanded the ability to collect environmental data, thus, the size and variety of these data-sets have likewise grown. Oftentimes, the collected data are deposited into files and databases where they sit in their separate and unique formats. Without easy to use visualization tools, it …

A Comprehensive Index For Assessing Environmental Stress In Animals, Terry L. Mader, Leslie J. Johnson, John B. Gaghan Dr

Nebraska Cooperative Extension: Faculty and Staff Publications

Numerous models and indices exist that attempt to characterize the effect of environmental factors on the comfort of animals and humans. Heat and cold indices have been utilized to adjust ambient temperature (Ta) for the effects of relative humidity (RH) or wind speed (WS) or both for the purposes of obtaining a “feels-like” or apparent temperature. However, no model has been found that incorporates adjustments for RH, WS, and radiation (RAD) over conditions that encompass hot and cold environmental conditions. The objective of this study was to develop a comprehensive climate index (CCI) that has application under a wide range …

Hydrodynamic Fin Function Of Brief Squid, Lolliguncula Brevis, William J. Stewart, Ian K. Bartol, Paul S. Krueger

Biological Sciences Faculty Publications

Although the pulsed jet is often considered the foundation of a squid's locomotive system, the lateral fins also probably play an important role in swimming, potentially providing thrust, lift and dynamic stability as needed. Fin morphology and movement vary greatly among squid species, but the locomotive role of the fins is not well understood. To begin to elucidate the locomotive role of the fins in squids, fin hydrodynamics were studied in the brief squid Lolliguncula brevis, a species that exhibits a wide range of fin movements depending on swimming speed. Individual squid were trained to swim in both the …

Regulation Of Pim1 Under Hypoxia In Prostate Cancer, Eva Sahakian

Loma Linda University Electronic Theses, Dissertations & Projects

A defining characteristic of solid tumors is the capacity to divide and spread under conditions of nutrient deprivation and limited oxygen availability. These microenvironmental stresses arise from structural abnormalities in tumor vessels that lead to aberrant microcirculation. Hypoxia acts as a physiological “selection pressure” in the progression of cancer by activating pathways and enhancing the expression of specific genes in tumor cells which eventually diminish their apoptotic potential. Ultimately, hypoxic microenvironment functions as a “stress factor”, selecting cells with the ability to survive and divide under anoxic conditions. The members of the PIM family of cytoplasmic serine threonine kinases are …

Isolation Of The Cytosolic C-Terminus Segment Of Mammalian Kca Channel A Subunit, Wilton Remigio

Loma Linda University Electronic Theses, Dissertations & Projects

The last 20 years of research into ion channels has unraveled unexpected features of the BK_ca channel as a rheostast for cell activity in excitable tissues and homeostatically fine tuning many biological activation processes in the cell. Great attention has been dedicated to the allosteric regulatory mecanisms by which the BK_ca channel is activated or inhibited. Most of these mechanisms point to the involvment of cytoplasmic, C-terminal, ‘tail’ domain of the channel. Many laboratories have cloned portions of the ‘tail’ domain in an attempt to to study specific regulatory sites. Very little is known about the BK ‘tail’ …

Alternative Methods And Forums To Optimize Public Participation In The Planning Process, Joseph James David

Master's Theses

“Public participation” takes on various forms in the realm of local government planning. Many planners stand behind the ideal of involving community, but participation in practice often fails to achieve this objective. The primary vehicle for local government participation is the public hearing, which is a formalized process that often elicits one-way communication from planner to public. The nature of a hearing is to inform the public about development applications or policy changes, expose governing body decisions to the public, and elicit reactions from interested members of the public. Significant effort is taken daily by local planning departments to promote …

Influences Of Environmental Education Programs On The Participant's Affinity For Nature, Justin Alan Schmillen

Master's Theses

This study was conducted to determine the change, and the factors influencing the change, in the participant’s affinity for nature resulting from an environmental education experience. In addition, this study also examined the change and factors of change in aspects of the participant’s affinity for nature that directly relate to marine and coastal resources and environments. An adapted version of the Affinity for Nature scale, an outcome measuring instrument used by the American Camp Association was used to collect data from participants (n=529) at Rancho El Chorro Outdoor School and Camp Ocean Pines, whose experience included an overnight component and …

Monocular Vision And Image Correlation To Accomplish Autonomous Localization, Matthew Paul Schlachtman

Master's Theses

For autonomous navigation, robots and vehicles must have accurate estimates of their current state (i.e. location and orientation) within an inertial coordinate frame. If a map is given a priori, the process of determining this state is known as localization. When operating in the outdoors, localization is often assumed to be a solved problem when GPS measurements are available. However, in urban canyons and other areas where GPS accuracy is decreased, additional techniques with other sensors and filtering are required.

This thesis aims to provide one such technique based on monocular vision. First, the system requires a map be generated, …

Growth Hormone Alters Components Related To Differentiation, Metabolism And Milk Synthesis And Secretion In Mac-T Cells, Tasha Lynn Johnson

Master's Theses

The mammary alveolar cell-T (MAC-T) cell line is able to uniformly differentiate and secrete casein proteins in response to dexamethasone, insulin and prolactin and is extensively used to study bovine mammary epithelial cell function. Growth hormone (GH) has been shown to increase milk protein synthesis both in vivo and in mammary cell models, and induce cytoskeletal rearrangement in 3T3 fibroblast cell line and a Chinese hamster ovary (CHO) cell line. Few studies have focused on identifying the mechanisms involved in differentiated MAC-T cells’ response to GH. We tested the hypothesis that MAC-T cells would respond directly to GH and that …

Lidar Remote Sensing Variables Predict Breeding Habitat Of A Neotropical Migrant Bird, Scott J. Goetz, Daniel Steinberg, Matthew G. G. Betts, Richard T. Holmes

Dartmouth Scholarship

A topic of recurring interest in ecological research is the degree to which vegetation structure influences the distribution and abundance of species. Here we test the applicability of remote sensing, particularly novel use of waveform lidar measurements, for quantifying the habitat heterogeneity of a contiguous northern hardwoods forest in the northeastern United States. We apply these results to predict the breeding habitat quality, an indicator of reproductive output of a well-studied Neotropical migrant songbird, the Black-throated Blue Warbler (Dendroica caerulescens). We found that using canopy vertical structure metrics provided unique information for models of habitat quality and spatial patterns of …

Ring-Necked Pheasant Nest Parasitism Of Sharp-Tailed Grouse Nests In Southwest North Dakota, Benjamin A. Geaumont, Kevin K. Sedivec, Christopher S. Schauer

The Prairie Naturalist

Numerous investigators have reported observations of ring-necked pheasant (RNP; Phasianus colchicus) eggs in nests of other gamebirds and waterfowl species (Errington and Hamerstrom 1938, Westemeier et al. 1998, Hagen et al. 2002, Krakauer and Kimball 2009). Previously recorded hosts include wild turkey (Meleagris gallopavo; Schmutz 1988), northern bobwhite (Colinus virginianus; Westemeier et al. 1989), greater prairie-chickens (Tyrnpanuchus cupido; Westemeier et al. 1998), and lesser prairie-chickens (T. pallidicinctus; Hagen et al. 2002). The reported occurrence of nest parasitism during these studies has generally been low with the highest reported occurrences found in …

Actor-Network Theory Of Cosmopolitan Education, Hiro Saito

Research Collection School of Social Sciences

In the past, philosophers discussed cosmopolitanism as a normative ideal of allegiance to humanity as a whole. A debate among social theorists, however, has examined cosmopolitanism as an incipient empirical phenomenon: an orientation of openness to foreign others and cultures. This paper introduces actor-network theory to elaborate the social-theoretical conception of cosmopolitanism. In light of the actor-network theory of cosmopolitanism, the paper proposes cosmopolitan education that aims to foster in students three dispositions: to extend attachments to foreign people and objects; to understand transnational connections in which their lives are embedded; and to act on these attachments and understandings to …

Fulfilling Government 2.0'S Promise With Robust Privacy Protections, Danielle K. Citron

Faculty Scholarship

The public can now “friend” the White House and scores of agencies on social networks, virtual worlds, and video-sharing sites. The Obama Administration sees this trend as crucial to enhancing governmental transparency, public participation, and collaboration. As the President has underscored, government needs to tap into the public’s expertise because it doesn’t have all of the answers.

To be sure, Government 2.0 might improve civic engagement. But it also might produce privacy vulnerabilities because agencies often gain access to individuals’ social network profiles, photographs, videos, and contact lists when interacting with individuals online. Little would prevent agencies from using and …
