The development of strongly predictive validated biomarkers is essential for the field of immuno-oncology (IO) to advance. The highly complex, multifactorial data sets required to develop these biomarkers necessitate effective, responsible data-sharing efforts in order to maximize the scientific knowledge and utility gained from their collection. While the sharing of clinical- and safety-related trial data has already been streamlined to a large extent, the sharing of biomarker-aimed clinical trial derived data and data sets has been met with a number of hurdles that have impaired the progression of biomarkers from hypothesis to clinical use. These hurdles include technical challenges associated …

Childhood Trauma And Attachment, Marcia Mihalovic
Counselor Education Capstones
According to statistics, 13% of children by the age of nine will have experienced 4 or more trauma related events (Finkelor et al., 2007, as cited by Cummings et al., 2017). These traumatic events have been linked to increased potential for health, educational, social-emotional, and relational concerns in a child’s future. Additionally, these trauma events have a significant impact on the child’s developing brain. Studies as explored in this paper, link the forming of secure attachments as vital. to resiliency and brain rewiring. The proposed parent/caregiver psychoeducation program consists of interwoven aspects from The Whole-Brain Child (Siegel, 2015), Trust-Based Relational …
Private Farms, Public Power: Governing The Lives Of Dairy Cattle, Jessica Eisen
Private Farms, Public Power: Governing The Lives Of Dairy Cattle, Jessica Eisen
Journal of Food Law & Policy
It is widely assumed that laws governing dairy productioninclude substantial protection of animals’ interests—that in some way the state is regulating the treatment of farmed animals and protecting them against the worst excesses of their owners’ selfinterest. In fact, across jurisdictions in Canada and the United States, the standards governing farmed animal protection are not established by elected lawmakers or appointed regulators, but are instead primarily defined by private, interested parties, including producers themselves. As scholars of animal law have noted, this has contributed to weak and ineffectual legal protection of the interests of farmed animals. The present study will …
Can Small Farmers Survive?: Problems Of Commercializing The Milk Value Chain In Pakistan, Erum Sattar
Can Small Farmers Survive?: Problems Of Commercializing The Milk Value Chain In Pakistan, Erum Sattar
Journal of Food Law & Policy
Milk in Pakistan is infused with the self-understanding of a nation. British colonial administrators laid the modern-day foundations of the country’s structure through land grants to small farmers. In an agricultural country where nearly forty percent of the population remains food insecure, rearing animals is a way of life in the rural areas where milk remains an important source of animal protein. Selling the daily surplus that families don’t consume is a significant source of earnings for cash poor families – and here an unprecedented change is taking place within dairy management and milk procurement systems. The scale of this …
The U.S. Dairy Industry In The 20th And 21st Century, George B. Frisvold
The U.S. Dairy Industry In The 20th And 21st Century, George B. Frisvold
Journal of Food Law & Policy
At the beginning of the 20th Century, the U.S. dairy industry was comprised of millions of small-scale operations producing for their own or for very local consumption. By the end of the 20th Century, the industry was dominated by large-scale producers marketing products via large cooperatives. Improvements in transportation, advances in animal breeding and feeding technologies, and scale economies have allowed the industry to be more competitive on global markets, where there is now active international trade in dairy products. Major government programs to support dairy farm income date back to Depression-era problems facing the industry. Federal programs to support …

Sensory Approach To Self-Regulation For Adolescent Survivors Of Sex Trafficking: An Occupational Therapist's Perspective, Elyse Harmon
Sensory Approach To Self-Regulation For Adolescent Survivors Of Sex Trafficking: An Occupational Therapist's Perspective, Elyse Harmon
Student Capstone Papers
Adolescent survivors of sex trafficking (SST) are susceptible to being in a continual dysregulated arousal state due to lack of mastery in self-regulation. During the trafficking experience, many adolescent SST experience severe trauma and are deprived of opportunities that foster essential regulatory capacities needed for occupational engagement. The use of sensory-based approaches that focus on addressing arousal dysregulation and the impact it has on occupation is an evidence-based practice grounded in occupational therapy research.
This capstone sought to support community reintegration for adolescent SST through the development of sensory-based programming that fosters self-regulation, a skill necessary for occupational participation. A …

Large (48-g), isonitrogenous doses of rice and whey protein have previously been shown to stimulate similar adaptations to resistance training, but the impact of consuming smaller doses has yet to be compared. We evaluated the ability of 24-g doses of rice or whey protein concentrate to augment adaptations following 8 weeks of resistance training.
A Theacrine-Based Supplement Increases Cellular Nad+ Levels And Affects Biomarkers Related To Sirtuin Activity In C2c12 Muscle Cells In Vitro, Petey W. Mumford, Shelby C. Osburn, Carlton D. Fox, Joshua S. Godwin, Michael D. Roberts
A Theacrine-Based Supplement Increases Cellular Nad+ Levels And Affects Biomarkers Related To Sirtuin Activity In C2c12 Muscle Cells In Vitro, Petey W. Mumford, Shelby C. Osburn, Carlton D. Fox, Joshua S. Godwin, Michael D. Roberts
Faculty Scholarship
There is evidence in rodents to suggest that theacrine-based supplements modulate tissue sirtuin activity as well as other biological processes associated with aging. Herein, we examined if a theacrine-based supplement (termed NAD3) altered sirtuin activity in vitro while also affecting markers of mitochondrial biogenesis. The murine C2C12 myoblast cell line was used for experimentation. Following 7 days of differentiation, myotubes were treated with 0.45 mg/mL of NAD3 (containing ~2 mM theacrine) for 3 and 24 h (n = 6 treatment wells per time point). Relative to control (CTL)-treated cells, NAD3 treatments increased (p < 0.05) Sirt1 mRNA levels at 3 h, as well as global sirtuin activity at 3 and 24 h. Follow-up experiments comparing 24 h NAD3 or CTL treatments indicated that NAD3 increased nicotinamide phosphoribosyltransferase (NAMPT) and SIRT1 protein levels (p < 0.05). Cellular nicotinamide adenine dinucleotide (NAD+) levels were also elevated nearly two-fold after 24 h of NAD3 versus CTL treatments (p < 0.001). Markers of mitochondrial biogenesis were minimally affected. Although these data are limited to select biomarkers in vitro, these preliminary findings suggest that a theacrine-based supplement can modulate select biomarkers related to NAD+ biogenesis and sirtuin activity. However, these changes did not drive increases in mitochondrial biogenesis. While promising, these data are limited to a rodent cell line and human muscle biopsy studies are needed to validate and elucidate the significance of these findings.
Prevention Of Pediatric Mortality Associated With Malaria: An Exhaustive Literature Review, Taylor Mosley
Prevention Of Pediatric Mortality Associated With Malaria: An Exhaustive Literature Review, Taylor Mosley
The Eleanor Mann School of Nursing Undergraduate Honors Theses
Malaria, a disease that is preventable yet frequently fatal, disproportionately affects pediatric African populations at a rate that results in a child under the age of 5 dying every two minutes. Since 1955, the World Health Organization has contributed to a significant reduction in the morbidity and mortality of malaria; however, progress has stalled in recent years. In some countries, particularly those in sub-Saharan Africa, cases have increased since 2015. This literature review seeks to identify factors associated with this incline, as well as what interventions can have the greatest impact to prevent pediatric mortality in areas with the largest …

Calorie Restriction For Enhanced Longevity: The Role Of Novel Dietary Strategies In The Present Obesogenic Environment, James L. Dorling, Corby K. Martin, Leanne M. Redman
Clinical Research Faculty Publications
Calorie restriction (CR) is a potent modulator of longevity in multiple species. A growing body of evidence shows that sustained periods of CR without malnutrition improves risk factors involved in the pathophysiology of type 2 diabetes, cardiovascular diseases, cancer, and neurological disorders in humans. Innovative dietary strategies such as intermittent fasting and protein restriction have recently emerged as alternative approaches that improve markers of aging. Some of these newer strategies might provide benefits for healthy aging with little to no CR and therefore, compared to traditional CR, may be easier to follow. Further to providing an update of CR studies …

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Iron homeostasis offers a significant bacterial vulnerability because pathogens obtain essential iron from their mammalian hosts, but host-defenses maintain vanishingly low levels of free iron. Although pathogens have evolved mechanisms to procure host-iron, these depend on well-regulated iron homeostasis. To disrupt iron homeostasis, our work has targeted iron mobilization from the iron storage protein bacterioferritin (BfrB) by blocking a required interaction with its cognate ferredoxin partner (Bfd). The blockade of the BfrB–Bfd complex by deletion of the bfd gene (∆bfd) causes iron to irreversibly accumulate in BfrB. In this study we …

Aedes albopictus, the Asian tiger mosquito, is an important nuisance mosquito species and known vector of arboviruses such as dengue, chikungunya, and Zika. Despite their cosmopolitan distribution around the world, there is a paucity of accurate predictive models based on rates of development at different temperatures (degree-day models). These types of models can benefit mosquito control districts by predicting when to target early-season larval development, when populations are likely at their lowest levels. In this study, we determined the effect of temperature and nutrient levels on the development rates and male and female adult size of 2 Ae. albopictus populations: …

Objective: Estrogen protects animals from obesity through estrogen receptor α (ERα), partially by inhibiting overeating in animals fed ad libitum. However, the effects of estrogen on feeding behavior in hungry animals remain unclear. In this study, we examined the roles of 17β-estradiol (E2) and ERα in the regulation of feeding in hungry female animals and explored the underlying mechanisms. Methods: Wild-type female mice with surgical depletion of endogenous estrogens were used to examine the effects of E2 supplementation on acute refeeding behavior after starvation. ERα-C451A mutant mice deficient in membrane-bound ERα activity and ERα-AF20 mutant mice lacking ERα transcriptional activity …

Brain glucose-sensing neurons detect glucose fluctuations and prevent severe hypoglycemia, but mechanisms mediating functions of these glucose-sensing neurons are unclear. Here we report that estrogen receptor-α (ERα)-expressing neurons in the ventrolateral subdivision of the ventromedial hypothalamic nucleus (vlVMH) can sense glucose fluctuations, being glucose-inhibited neurons (GI-ERαvlVMH) or glucose-excited neurons (GE-ERαvlVMH). Hypoglycemia activates GI-ERαvlVMH neurons via the anoctamin 4 channel, and inhibits GE-ERαvlVMH neurons through opening the ATP-sensitive potassium channel. Further, we show that GI-ERαvlVMH neurons preferentially project to the medioposterior arcuate nucleus of the hypothalamus (mpARH) and GE-ERαvlVMH neurons preferentially project to the dorsal Raphe nuclei (DRN). Activation of ERαvlVMH …

Homeotherms maintain a stable internal body temperature despite changing environments. During energy deficiency, some species can cease to defend their body temperature and enter a hypothermic and hypometabolic state known as torpor. Recent advances have revealed the medial preoptic area (MPA) as a key site for the regulation of torpor in mice. The MPA is estrogen-sensitive and estrogens also have potent effects on both temperature and metabolism. Here, we demonstrate that estrogen-sensitive neurons in the MPA can coordinate hypothermia and hypometabolism in mice. Selectively activating estrogen-sensitive MPA neurons was sufficient to drive a coordinated depression of metabolic rate and body …

Review Of The Validity And Feasibility Of Image-Assisted Methods For Dietary Assessment, Christoph Höchsmann, Corby K. Martin
Clinical Research Faculty Publications
Accurately quantifying dietary intake is essential to understanding the effect of diet on health and evaluating the efficacy of dietary interventions. Self-report methods (e.g., food records) are frequently utilized despite evident inaccuracy of these methods at assessing energy and nutrient intake. Methods that assess food intake via images of foods have overcome many of the limitations of traditional self-report. In cafeteria settings, digital photography has proven to be unobtrusive and accurate and is the method of choice for assessing food provision, plate waste, and food intake. In free-living conditions, image capture of food selection and plate waste via the user’s …

We use a multivariate multilevel model to study the links between physical fitness (PF) and gross motor coordination (GMC) and investigate the influence of predictors affecting their levels across age. We sampled 7918 Peruvians, aged 6-15 years, from sea-level, Amazon region and high-altitude. Composite markers of GMC and PF were derived (GMCz and PFz, respectively). BMI, biological maturation, and stunting were assessed. School characteristics were obtained via an objective audit. School contexts explained 35% of the associations between PFz and GMCz, whereas children's characteristics explained 65% of the total variation. On average, with increasing age, there was a greater increase …

The central nervous system controls feeding behavior and energy expenditure in response to various internal and external stimuli to maintain energy balance. Here we report that the newly identified transcription factor zinc finger and BTB domain containing 16 (Zbtb16) is induced by energy deficit in the paraventricular (PVH) and arcuate (ARC) nuclei of the hypothalamus via glucocorticoid (GC) signaling. In the PVH, Zbtb16 is expressed in the anterior half of the PVH and co-expressed with many neuronal markers such as corticotropin-releasing hormone (Crh), thyrotropin-releasing hormone (Trh), oxytocin (Oxt), arginine vasopressin (Avp), and nitric oxide synthase 1 (Nos1). Knockdown (KD) of …
