Effect Of Vitamin D Metabolites On Bone Histomorphometry In Healthy Black And White Women: An Attempt To Unravel The So-Called Vitamin D Paradox In Blacks, S Qiu, George Divine, Sudhaker D Rao, Sudhaker D. Rao

Endocrinology Articles

An apparent vitamin D paradox, characterized by lower serum 25-hydroxyvitamin D (25(OH)D) levels and higher bone mineral density, is present in black population. In contrast, blacks have higher serum 1,25-dihydroxyvitamin D (1,25(OH)(2)D) levels. The effect of 1,25(OH)(2)D on the skeleton is not fully understood. We examined serum 25(OH)D, 1,25(OH)(2)D and bone histomorphometry in 50 black and white women (25 each) matched for age, menstrual status, and BMI. Histomorphometric indices related to bone structure, remodeling and mineralization were measured in cancellous bone in iliac bone biopsies. Data analyses led to the following results: 1) serum 25(OH)D was significantly lower and 1,25(OH)(2)D …

Socio-Ecological Challenges Of Hydroelectric Dams Among Ethnic Minorities In Northern Laos, Saleh Ahmed, Paige Liquin

Global Studies Faculty Publications and Presentations

Globally, hydroelectric dams are increasingly considered to be a sustainable source of renewable energy. Many countries have invested in hydroelectric projects to boost the local and national economies. The findings of recent hydroelectric projects are mixed. Even though the construction of these dams has provided immediate benefits to surrounding communities, long-term negative implications of hydroelectric development have called into question the true sustainability of hydroelectric projects. These negative impacts of hydroelectric dams include the resettlement of marginalized communities, in addition to significant alterations to the local environment and economy. Taking both the positive and negative impacts of hydroelectric development into …

The Dictyostelium Discoideum Genome Lacks Significant Dna Methylation And Uncovers Palindromic Sequences As A Source Of False Positives In Bisulfite Sequencing, Robert Drewell, Tayla C. Cormier, Jacob L. Steenwyk, James St Denis, Javier F. Tabima, Jacqueline Dresch, Denis A. Larochelle

Biology

DNA methylation, the addition of a methyl (CH3) group to a cytosine residue, is an evolutionarily conserved epigenetic mark involved in a number of different biological functions in eukaryotes, including transcriptional regulation, chromatin structural organization, cellular differentiation and development. In the social amoeba Dictyostelium, previous studies have shown the existence of a DNA methyltransferase (DNMA) belonging to the DNMT2 family, but the extent and function of 5-methylcytosine in the genome are unclear. Here, we present the whole genome DNA methylation profile of Dictyostelium discoideum using deep coverage replicate sequencing of bisulfite-converted gDNA extracted from post-starvation cells. We find an overall …

Fast-Tracks And Prizes: A Multi-Pronged Approach To Incentivizing Green Technology Innovation, Benjamin Desch

Washington Law Review

Faced with the ever-worsening climate crisis, many nations—including the United States—have increasingly recognized the urgent need for rapid advancements in green, clean, and sustainable technologies. Patents play a fundamental role in incentivizing technological innovation, but the traditional patent process is too slow to match the urgency of the climate crisis. At the same time, the marketplace significantly undervalues green technology patents because they confer benefits to third parties not involved in the transaction (referred to as “positive externalities”). To address the urgency issue, patent “fast-track” programs have been implemented to speed up the patent application review process. To mitigate the …

The Credibility Effect: Defamation Law And Audiences, Yonathan A. Arbel

Articles

What should be the legal response to false statements? In the context of defamation law, courts try to set a standard that balances the interests of speakers and their potential targets. This article empirically demonstrates an unappreciated effect of such decisions on third parties: a credibility effect. Using a series of lab experiments, I find that defamation law makes individuals more trusting of reports from various media. This credibility effect is desirable when the report is true but can lead to unintended consequences in the case of misinformation. In particular, the credibility effect is shown to cast a stigma on …

Evaluation Of Potential Surrogates For Listeria Monocytogenes In Fresh Citrus-Specific Validation Studies, Kimiko Grace Casuga

Master's Theses

The FSMA Produce Safety Rule (PSR) requires citrus packers to more closely assess, manage, and monitor food safety risks. Although there have been no foodborne illness outbreaks and only one recall in fresh citrus, the risk of pathogens coming in on the fruit and cross contamination during washing still exists. Packhouses have dynamic washing systems and in-plant validations may be the only way to demonstrate compliance with the PSR. In-plant validations use surrogates in place of pathogens, and none have been identified or validated for citrus. The aim of this research was to identify a surrogate for use in fresh …

Reducing Scope 3 Emissions By Investing In Regenerative Agriculture In Supply Chains, Stephanie Cain

Master's Theses

The agricultural industry has an opportunity to shift to a more sustainable practice that helps restore vital topsoil, improve water quality, reduce environmental impact, and sequester atmospheric carbon into the vast soil carbon pool. However, to implement these practices at considerable scale, agricultural producers require access to resources and capital they rarely have and can be difficult to acquire. As a company, investing in regenerative agriculture in supply chains can lead to reduced Scope 3 emissions, more resilient supply chains, and better marketability as an investment fund, an employer, and a brand. Insetting regenerative agriculture can protect supply chains against …

Food For Thought: The Effects Of Feeding On Neurogenesis In The Ball Python, Python Regius, Hannah F. Bow

Master's Theses

Pythons are a well-studied model of postprandial physiological plasticity. Consuming a meal has been shown by past work to evoke a suite of physiological changes in pythons and elicit one of the largest documented increases in post-feeding metabolic rates relative to resting values. However, little is known about how this plasticity manifests in the brains of ball pythons, Python regius. Previous work using the cell-birth marker 5-bromo-12’-deoxyuridine (BrdU) has shown that cell proliferation in the python brain increases six days following meal consumption. This study aimed to confirm these findings and build on them in the long term by …

Effects Of Mature Recombinant Gdf9 And Bmp15 On In-Vitro Maturation Of Bovine Oocytes And Subsequent Embryo Development And Effects Of Antioxidants On Blastocyst Re-Expansion Rates, Jamie Thompson

Master's Theses

In-vitro produced embryos (IVP) differ greatly from in-vivo derived embryos (IVD) in gene expression, metabolism, development, and cryotolerance which limit the widespread use of this technology. In-vitro maturation (IVM) is one of the most important components for successful in-vitro embryo development. Growth differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15) have been found to be essential during oocyte maturation and thus female fertility. These proteins are oocyte secreted factors (OSFs) and are produced with pro- and mature protein regions where the pro-regions are thought to aid in protein folding and dimerization where heterodimerization the two proteins has been …

Understanding And Applying Sar To Ideological And Nation- State-Sponsored Cybercrimes, Thomas J. Holt, Steve Chermak, Joshua D. Freilich, Emily Greene-Colozzi, National Counterterrorism Innovation, Technology, And Education Center

Reports, Projects, and Research

The use of computer hacking, malicious software, and other forms of cyberattacks against U.S. infrastructure has increased dramatically since the 1990s. Many of these attacks target corporations and individuals for instrumental economic gain, such as the theft of personal information for use in fraud. Ideologically motivated attacks also occur, though the degree to which they are understood or documented is generally limited. For instance, jihadi groups have expressed an interest in cyberattacks since the early 2000s (see Holt et al., 2022). Similarly, DHS (2009) noted in the late 2000s that they expected cyberattacks from environmental or animal liberation-focused groups to …

Re-Imagining The Duty To Consult: Requiring A Substantive Outcome To Further Reconciliation, Naomi Austin

Dalhousie Journal of Legal Studies

The Crown has a duty to consult with Indigenous peoples on actions that may adversely affect claimed Indigenous interests that have not yet been established as recognized rights. Currently, the duty to consult remains a procedural obligation that does not require the consent of the Indigenous claimants to move forward. The crux of the duty to consult is to reconcile Crown and Indigenous interests. This paper explores how the duty to consult can better promote reconciliation by requiring a substantive outcome. Requiring a substantive outcome enhances the ability of Indigenous claimants to protect their own interests in the face of …

Faculty, Staff and Student Publications

BACKGROUND: Exposures to environmental contaminants can be influenced by social determinants of health. As a result, persons living in socially disadvantaged communities may experience disproportionate health risks from environmental exposures. Mixed methods research can be used to understand community-level and individual-level exposures to chemical and nonchemical stressors contributing to environmental health disparities. Furthermore, community-based participatory research (CBPR) approaches can lead to more effective interventions.

OBJECTIVES: We applied mixed methods to identify environmental health perceptions and needs among metal recyclers and residents living in disadvantaged neighborhoods near metal recycling facilities in Houston, Texas, in a CBPR study, Metal Air Pollution Partnership …

Russian L2 Learners' And Teachers' Perceptions Of Learning Affordances, Marina Tsylina, Jose Luis Garrido Rivera, Hadis Ghaedi

Russian Language Journal

The environment offers a variety of resources for language learning and teaching. However, students and teachers might not recognize the same affordances or may perceive them differently. The mismatch between instructors’ and learners’ perceived affordances may result in ineffective use of time for both students and teachers, lower student motivation, and retard the language learning process. The study draws on the ecological approach (van Lier, 2000) to second language acquisition to investigate L2 Russian learners’ and teachers’ perceptions of language learning affordances, i.e., any physical objects, online materials, humans, and other resources which are embedded in the environment, and emerge …

Chronic, Mild Hypothermic Environmental Temperature Does Not Ameliorate Cognitive Deficits In An Alzheimer's Disease Mouse., Samuel Mcfadden, Lindsey N Sime, Makayla F Cox, Caleigh A Findley, Mackenzie R Peck, Kathleen Quinn, Yimin Fang, Andrzej Bartke, Erin R Hascup, Kevin N Hascup

Articles

Metabolic dysfunction increases with age and is a contributing factor to Alzheimer's disease (AD) development. We have previously observed impaired insulin sensitivity and glucose homeostasis in the APP/PS1 model of AD. To improve these parameters, we chronically exposed male and female mice to mild hypothermic environmental temperature (eT), which positively modulates metabolism. Although a hypothermic eT normalized insulin sensitivity, glucose tolerance was still impaired in both sexes of AD mice. We observed increased plasma glucagon and B-cell activating factor in both sexes, but additional sexually dimorphic mechanisms may explain the impaired glucose homeostasis in AD mice. Hepatic Glut2 was decreased …
