No Strong Evidence Of The Protein Leverage Hypothesis In Pregnant Women With Obesity And Their Infants, Maryam Kebbe, Jasper Most, Abby D. Altazan, Leanne M. Redman

Clinical Research Faculty Publications

Objective: The goal of this study was to investigate the role of dietary protein on macronutrient and energy intake, maternal adiposity during pregnancy, and infant adiposity at birth. Methods: In 41 women with obesity, early-pregnancy (13–16 weeks) protein intake was assessed with food photography and expressed as a ratio of Estimated Average Requirements (EAR) in pregnancy for protein (0.88 g/kg/d), herein “protein balance.” Energy intake was measured by the intake-balance method, gestational weight gain as grams per week, and fat mass by a three-compartment model. Spearman correlations and linear models were computed using R version 4.1.1 (p < 0.05 considered significant). Results: Women had a mean (SD) age of 27.5 (4.8) years and a pregravid BMI of 34.4 (2.9), kg/m2, and the majority were non-White (n = 23, 56.1%). Protein balance in early pregnancy was not significantly associated with energy intake across mid and mid/late pregnancy (β = 328.7, p = 0.30 and β = 286.2, p = 0.26, respectively) or gestational weight gain (β = 117.0, p = 0.41). Protein balance was inversely associated with fat mass in early, mid, and late pregnancy (β = −10.6, p = 0.01, β = −10.4, p = 0.03, β = −10.3, p = 0.03, respectively). Protein balance did not predict infant adiposity at birth (p > 0.05). Conclusions: Low …

The Possibility Of A Global Civilization, Robert Elliott Allinson

Comparative Civilizations Review

This article inquires into the question of what is civilization. It considers that a sine qua non of a civilization is a non-violent culture. It investigates the concept of violence and extends the concept to cover examples of citizens who live in conditions of poverty, ill health, lack of food, lack of education, lack of adequate housing, and inadequate living conditions. The argument in the article is that a civilization that allows such conditions to exist perpetrates violence upon its citizens and therefore does not deserve the appellation, ‘civilization.’ Those citizens who do not protest against such violence are not …

Monitoring Wise Civilization By Creating An Index, Andrew Targowski

Comparative Civilizations Review

The Wise Civilization Index will assess how wise we are in developing and living in a sustainable civilization.

Recently, people have started to worry about the state of the climate. This has been reflected in the finding that the climate temperature should be kept to a growth of below two degrees Celsius by 2100 to save our species from a slow death (The Paris Agreement of 2015). After all, raising the human body temperature by two degrees threatens illness and even death by four degrees. The same (relatively) can be done with Earth. However, apart from the climate, the problem …

Research outputs 2022 to 2026

The Dominantly Inherited Alzheimer Network (DIAN) is an international collaboration studying autosomal dominant Alzheimer disease (ADAD). ADAD arises from mutations occurring in three genes. Offspring from ADAD families have a 50% chance of inheriting their familial mutation, so non-carrier siblings can be recruited for comparisons in case–control studies. The age of onset in ADAD is highly predictable within families, allowing researchers to estimate an individual’s point in the disease trajectory. These characteristics allow candidate AD biomarker measurements to be reliably mapped during the preclinical phase. Although ADAD represents a small proportion of AD cases, understanding neuroimaging-based changes that occur during …

Utilizing Crispr Cas9 To Visualize Dopamine Receptors In Caenorhabditis Elegans, Lauren Michelle Velasquez

Electronic Theses, Projects, and Dissertations

Dopamine (DA) is a neurotransmitter with imperative implications in many functions including movement, reward, and cognition. Studying the pathways of dopaminergic neurons at multiple levels allows us to understand the ways in which these systems can go wrong. We study dopamine in a model system such as the worm Caenorhabditis elegans because of its relatively simple and well-characterized nervous system. DA is involved in regulating chemosensory behaviors in worms. The purpose of this research project is to definitively answer the following question: Are the dopamine receptors DOP-1 and DOP-4 expressed in chemosensory neurons? Previous reporter assays show that neither of …

To further reduce animal usage, methods that will lessen reliance upon traditional animal toxicology testing and increase the usage of alternative, high throughput toxicology screening methods are being explored. One such method is the utilization of biomarkers and bioreporters in model organisms such as Drosophila melanogaster. The biomarkers, HSP22 and HSP70 have been successfully utilized in various studies involving Drosophila melanogaster bioreporter constructs to evaluate chemical toxicity. In this study, both an in vivo and in vitro HSP22 and …

Interpreting The Taiping Rebellion, Thomas Donovan

Electronic Theses, Projects, and Dissertations

This paper offers an evaluation of the Chinese Nationalist and Communist interpretations of the Taiping Rebellion (December 1851- August 1864). As the largest uprising of the time, whose importance was central to the course of modern Chinese history, prominent members of both the CCP and the KMT perceived the seeds of their political movements in the Taiping Rebellion. What evidence supports their claims, to what extent they are rational, and how their narrations illuminate aspects of the rebellion is our primary task. In addition, the particular Taiping creed, and the many interpretations of it, will be analyzed and a cross-cultural …
