  1. PTHrP 1-141 and 1-86 Increase In Vitro Bone Formation

    Hildreth III, Blake Eason
    Background—Parathyroid hormone-related protein (PTHrP) has anabolic effects in bone, which has led to the clinical use of N-terminal fragments of PTHrP and PTH. Since 10-20% of fractures demonstrate healing complications and osteoporosis continues to be a debilitating disease, the development of bone-forming agents is of utmost importance. Due to evidence that regions of PTHrP other than the N-terminus may have bone-forming effects, this study was designed to compare the effects of full-length PTHrP 1-141 to N-terminal PTHrP 1-86 on in vitro bone formation. Materials and methods—MC3T3-E1 pre-osteoblasts were treated once every 6 days for 36 days with 5, 25, and 50 pM of PTHrP 1-141 or 1-86 for...

  4. From Brownfields to Greenfields: Assessing the Environmental Justice of Cleaning Up Brownfields

    Eckerd, Adam
    Issues of environmental injustice in siting of environmental hazards are well known. Based on past research, the expectation is that lower socioeconomic status populations are systematically subject to higher levels of environmental risk in their communities. In this paper, I investigate whether similar patterns appear prevalent in environmental improvement as well. First, I assess the characteristics of the communities in which brownfield sites are currently located. Then, I compare the likelihood and prioritization of cleaning up brownfield sites based on the composition of their neighborhoods. I find that while sites in communities with larger minority populations are likely to move...

  5. Examining Upper and Lower Case Letter Knowledge with Item Response Theory

    Pentimonti, Jill
    Children’s alphabet knowledge is among the strongest predictors of children’s early literacy skills (Scarborough, 1998) and is a key component of emergent literacy development (Whitehurst & Lonigan, 1998). Alphabet knowledge is typically conceptualized as total number of letters a child knows (i.e., a simple sum score). Therefore, the fact that some letters are more likely to be known than others (i.e., inter-letter differences) is not taken into account in alphabet knowledge assessments. However, research studies suggest that specific alphabet knowledge does vary in acquisition (McBride-Chang, 1999), indicating that researchers and educators should consider inter-letter differences in alphabet knowledge. In addition,...

  7. Small Scale Wind Turbines Optimized for Low Wind Speeds

    Letcher, Todd
    A combination of common vertical axis wind turbines (VAWT) rotors was designed and tested for optimal performance in low wind speeds. The Savonius rotor creates high torque and is self-starting even at low wind speeds, but is relatively low in efficiency rating. The Savonius rotor is used to start the straight bladed Darrieus rotor. The Darrieus rotor is not a self starting rotor, but has much higher efficiency than the Savonius rotor. The combination of rotors increases the total power of the turbine in lower wind speeds.

  10. Photoperiodic Regulation of Affective Responses and Hippocampal Cell Morphology in Siberian Hamsters

    Workman, Joanna
    Seasonal affective disorder (SAD) is characterized by depressive episodes during winter that are alleviated during summer and by morning bright light treatment. Currently, there is no animal model of SAD. However, it may be possible to use rodents that respond to day length to understand how day length can shape brain and behavior in humans. For instance, Siberian hamsters use day length to time seasonal cycles of reproduction and also exhibit changes in nonreproductive behaviors dependent on day length. Specifically, short-day Siberian hamsters increase floating in the forced swim test (a behavioral test used to screen antidepressant compounds). Current research...

  14. Analysis of Mitochondrial Morphology in Cells Experiencing a "Heart Attack"

    Giedt, Randy
    Vascular endothelial cell (EC) dysfunction immediately following the recanalization of a blocked artery (known as reperfusion, RP) is attributed to the cellular generation of superoxide radicals and other reactive oxygen species (ROS). Nitric oxide (NO) is known to promote ROS production from the cell mitochondria. Our lab discovered that cultured EC exposure to fluid mechanical shear stress results in endogenous NO-mediated mitochondrial ROS production. Ischemia (I)/RP-induced EC injury occurs primarily due to mitochondrial ROS production, and the decline in bioavailable NO (due to the reaction of NO with superoxide) impairs the EC-dependent dilation in the heart coronary vessels. In general,...

  16. Donut dynamics: localized allosteric activation and ligand-binding kinetics in the ring-shaped ligand-responsive regulatory protein TRAP

    Kleckner, Ian R.
    The overarching goal of this research is to gain insight into mechanisms of ligand-modulated gene regulation by studying the trp RNA-binding Attenuation Protein (TRAP). TRAP is a biological Trp-sensor endogenous in bacilli: when cellular free Trp concentration is low, TRAP predominates in the inactive apo form and the micro-organism may synthesize additional Trp using a specific molecule of RNA. However, when the Trp concentration rises TRAP may bind this excess Trp and thus become activated to bind that RNA molecule. When TRAP binds the RNA, it disables downstream production of additional Trp. Thus, the micro-organism employs TRAP in this simple...

  20. Borderlanguage: Language Policy, Ideology and Identity in Ukraine

    Vdovichenko, Susan
    Language and identity are inextricably intertwined, and language policy directly impacts people's lives for more than just communication. In Ukraine, after nearly a century of widely varying linguistic policies and customs, Ukrainian was declared the sole official language in 1991. Almost two decades later, language issues remain critical in politics, perhaps because of the link between language and identity, and complicated by linguistic ideology. In part because of its early history, Ukrainian had been perceived by many as only suitable for village use and regarded as substandard. However, Ukrainian is now the only official language of education and government. This...
