Extreme Events Reveal An Alimentary Limit On Sustained Maximal Human Energy Expenditure, Caitlin Thurber, Lara R. Dugas, Cara Ocobock, Bryce Carlson, John R. Speakman, Herman Pontzer

Publications and Research

The limits on maximum sustained energy expenditure are unclear but are of interest because they constrain reproduction, thermoregulation, and physical activity. Here, we show that sustained expenditure in humans, measured as maximum sustained metabolic scope (SusMS), is a function of event duration. We compiled measurements of total energy expenditure (TEE) and basal metabolic rate (BMR) from human endurance events and added new data from adults running ~250 km/week for 20 weeks in a transcontinental race. For events lasting 0.5 to 250+ days, SusMS decreases curvilinearly with event duration, plateauing below 3× BMR. This relationship differs from that of shorter events …

Omni-Gravity Hydroponics System For Spacecraft, Tara M. Prevo

Maseeh Summer Undergraduate Research Experience

Effective omni-gravity hydroponics will allow astronauts to supplement nutrition and further close the life cycle of water in orbit, lunar, and Martian conditions. This project determines the operational limits of the test cells for the Plant Water Management Hydroponics mission. A scaled 1-g channel was designed by Rihana Mungin to mimic full-scale performance in microgravity that could be tested terrestrially. This project sought to find the limits of operation of the 1-g test cells and identify failure modes that could pose a safety risk in space. The cells were filled at increments of 20% and cycled from 0.184 to 8.33 …

Pasture Chemoscapes And Their Ecological Services, Juan J. Villalba, Karen A. Beauchemin, Pablo Gregorini, Jennifer W. Macadam

Wildland Resources Faculty Publications

Ruminant livestock-production systems are between a rock and a hard place; they are experiencing increasing societal pressure to reduce environmental impacts in a world that demands increased food supply. Recent improvements in the understanding of the nutritional ecology of livestock by scientists may help livestock producers respond to these seemingly contradictory demands. Forages are nutrition and pharmacy centers with primary (nutrients) and plant secondary compounds (PSC; pharmaceuticals, nutraceuticals), which can provide multiple services for the proper functioning of agroecosystems. Legumes with lower contents of fiber and higher contents of nonstructural carbohydrates, coupled with different types and concentrations of PSC (e.g., …

Mitochondrial Activity And Skeletal Muscle Insulin Resistance In Kidney Disease, Jane E. Carré, C Affourtit

School of Biomedical Sciences

Insulin resistance is a key feature of the metabolic syndrome, a cluster of medical disorders that together increase the chance of developing type 2 diabetes and cardiovascular disease. In turn, type 2 diabetes may cause complications such as diabetic kidney disease (DKD). Obesity is a major risk factor for developing systemic insulin resistance, and skeletal muscle is the first tissue in susceptible individuals to lose its insulin responsiveness. Interestingly, lean individuals are not immune to insulin resistance either. Non-obese, non-diabetic subjects with chronic kidney disease (CKD), for example, exhibit insulin resistance at the very onset of CKD, even before clinical …

Engaged Communication Scholarship For Environmental Justice: A Research Agenda, Chad Raphael

Communication

As a discipline of crisis and care, environmental communication needs to address questions of environmental justice. This article argues that the most appropriate approach to studying environmental justice communication is engaged scholarship, in which academics collaborate with community partners, advocates, and others to conduct research. The article reviews prior engaged communication scholarship on environmental justice, and proposes four streams of future research, focused on news and information, deliberation and participation, campaigns and movements, and education and literacy.

A Mendelian Randomization Study Of Coronary Artery Disease And Three Amino Acids: Alanine, Glycine, And Glutamine, Allan Uribe

Dissertations and Theses

Cardiovascular disease is the leading cause of death worldwide. Coronary Artery Disease (CAD) accounts for the majority of those deaths. Observational studies have identified risk factors that have been helpful in lowering the death rate, including hypertension, high cholesterol, diabetes, smoking, physical inactivity and poor diet. The effects of these risk factors on CAD remain unclear. To clarify the effect of three amino acids, alanine, glutamine, and glycine on CAD I applied a two sample Mendelian randomization analysis to extensively genotyped observational data. In a sample with up to 184,000 individuals and approximately 60,000 controls, SNPs that reached genome wide …

Heatwaves And Novel Host Consumption Increase Overwinter Mortality Of An Imperiled Wetland Butterfly, Mariana Abarca, Elise A. Larsen, Leslie Ries

Biological Sciences: Faculty Publications

Disruptive effects of climate change include range shifts, phenological mismatches among consumers and producers, and population declines. While these biological alterations have been widely documented, studies identifying specific mechanisms linking climate change to population declines are scarce. Extreme events, such as heatwaves can have devastating effects on living organisms and are increasing in frequency as Earth warms. Hence, understanding the effects of heatwaves on insects is necessary to inform conservation efforts and to develop predictions of population dynamics under future climate scenarios. Here, we experimentally evaluated the effects of heatwaves on the survival and phenology of the Baltimore Checkerspot (Euphydryas …

Influence Of Hydration Status On Running Performance And Makers Of Psychological And Physiological Stress In High School Cross Country Runners, Joshua Granger

LSU Master's Theses

Adequate hydration is an important attribute to an individual’s health and wellbeing. This is highlighted in athletic populations, who are at great risk for hypohydration, regardless of age, sex, and sport. The rampant hypohydration observed in athletes is present at all levels of competition, from professional athletes, with access to substantial monetary and nutrition support to division 3 and recreational athletes who often face monetary challenges. This trend continues to trickle down to lower levels of competition, such as high school, where athletes often practice and compete in dehydrated states. Practicing in these hypohydrated states can cause health issues such …

Maximizing And Modeling Malonyl-Coa Production In Escherichia Coli, Tatiana Thompson Silveira Mello

LSU Master's Theses

In E. coli, fatty acid synthesis is catalyzed by the enzyme acetyl-CoA carboxylase (ACC), which converts acetyl-CoA into malonyl-CoA. Malonyl-CoA is a major building block for numerous of bioproducts. Multiple parameters regulate the homeostatic cellular concentration of malonyl-CoA, keeping it at a very low level. Understanding how these parameters affect the bacterial production of malonyl-CoA is fundamental to maximizing it and its bioproducts. To this end, competing pathways consuming malonyl-CoA can be eliminated, and optimal nutritional and environmental conditions can be provided to the fermentation broth. Most previous studies utilized genetic modifications, expensive consumables, and high-cost quantification methods, making …

Reproductive Parameters And Methodologies For The Culture Of Golden Topminnows (Fundulus Chrysotus) And Bluenose Shiners (Pteronotropis Welaka), Jacob A. Fetterman

LSU Master's Theses

The global ornamental fish trade has expanded over the past 20 years, requiring captive rearing methods to be improved or developed for species of interest. Aquaculture of desirable species is preferable over wild harvest to conserve natural habitats and biodiversity. This thesis focused on improving culture methods for Golden Topminnows Fundulus chrysotus and developing culture methods for Bluenose Shiners Pteronotropis welaka, both native fishes of the southeastern United States with ornamental demand. A combination of reproductive metric analyses, examination of historical collections, and captive spawning trials were employed to target specific objectives for each species. In female Golden Topminnows, …

What Is A Healthy Body? Asking For A Friend. A Mini Ethnography About Undergraduate Women At Seattle University And Their Relationships With Food And Exercise., Haley R. Witt

SUURJ: Seattle University Undergraduate Research Journal

Transitional periods have been identified as potential triggers for eating disorders in college students (Karges 2016). Risk factors for eating disorders can be biological, psychological, and sociocultural (National Eating Disorder Association 2018). The sociocultural risk of eating disorders includes weight stigma which, according to feminist philosopher Susan Bordo, can greatly impact the self-image of North American women. Bordo refers to the “ideal” female body as the “slender body,” one that is reflected and glorified in contemporary media (1993). Although undergraduate women are a potentially fragile population, as they are away from their childhood eating and exercise routines and in an …

Obesity, Food Swamps, And The Youth Of Guatemala City., Anne-Celine Jeffroy-Meynard

SUURJ: Seattle University Undergraduate Research Journal

This essay will explore obesity, body mass and nutrition transition as health concerns in Guatemala and Guatemala City’s youth population. Obesity can be caused by consuming more calories than are exerted, resulting in a high Body Mass Index. The proximate cause of an extreme weight gain can be linked to the overconsumption of energy-dense, nutrient-poor food, which marketing, urbanization, food deserts and food swamps have a direct correlation to influence. Although obesity is a global health concern, this essay will outline contributing factors which have led to a population facing severe nutritional changes, and will focus on Guatemala’s youth, being …

Reparative Practices: Invitations From Mundane Urban Ecologies, Emmy Laura Perez Fjalland, Kristine Samson

Nordes Conference Series

The paper proposes a reparative turn in co-design towards an attention and sensitivity to more-than-human world-making practices in our urban environments. The notion of ‘reparative’ hold strings with the reparative system that an organism starts when damage is experienced. Thinking-with this biological, cultural and performatively, we propose the reparative as the starting point for learning to notice life-giving potentialities in the Anthropocene. Reparative practices are ethical and political in the sense that we are searching for life-giving practices that can move us beyond design practices in the Anthropocene. Hence, by bringing attention to environmental enchantments related to sensory everyday practices …
