Beyond Translation: Increasing Accessibility To Nutrition Education For Foreign-Born Latine Adults, Karen L. Franck, Jennifer Ward, Lisa Fuller, Egla Delvo-Lopez, Chanta'l Rose Mar 2024

Beyond Translation: Increasing Accessibility To Nutrition Education For Foreign-Born Latine Adults, Karen L. Franck, Jennifer Ward, Lisa Fuller, Egla Delvo-Lopez, Chanta'l Rose

The Journal of Extension

About 20% of the U.S. population identifies as Latine. To engage these audiences, many Extension nutrition education programs have translated curricula and other resources into Spanish. Culturally responsive programs need to move beyond translation and address critical issues and needs specific to Latine audiences. We conducted focus groups with 118 foreign-born Latine adults across one state. Participants were interested in nutrition education programs involving the entire family including children offered by bilingual educators. They also wanted programs that focused on healthy meals that included foods from their culture of origin with common US foods.


A Nutritional Intervention To Improve Body Composition In Adolescent Athletes, Michael Ryan, Rosemary E. Borgerding, Kimberly L. Oliver Mar 2024

A Nutritional Intervention To Improve Body Composition In Adolescent Athletes, Michael Ryan, Rosemary E. Borgerding, Kimberly L. Oliver

Journal of Athlete Development and Experience

This study assessed the effectiveness of a sports nutrition intervention designed to improve body composition in 25 high-school male athletes over a 12-week period. Employing a mixed-methods approach within a quasi-experimental one-group pretest-posttest design, the intervention integrated nutrition education with the provision of food. Quantitative results revealed significant reductions in body fat percentage and fat mass, and an increase in fat-free mass. Qualitative insights highlighted the untapped nutritional potential of adolescents and emphasized the importance of accessibility and simplicity in driving compliance. The findings suggest that targeted nutritional interventions can positively impact adolescent athletes' body composition. The study underscores the …

Research Symposium

Introduction: Assessing nutrition knowledge in four-year-olds, a developmental stage marked by limited attention spans and varying comprehension abilities, is challenging with traditional methods. A reliable test is pivotal for establishing a foundation for future health interventions. We evaluated a 13-question nutrition and healthy habits test in Pre-K4 children to assess reliability and sensitivity to detect differences.

Methods: Calculations included Cronbach's alpha, kappa coefficient, McNemar analysis by item, and Bland-Altman plots for test-retest differences. Mixed model regression assessed the questionnaire's sensitivity by sex and association with age. Item response theory (IRT) models were employed, generating latent abilities for students and individual …


A Dietary Variety: Analyzing The Impacts Of Diverse Vs Worm-Exclusive Diets On The Blanding’S Turtle (Emydoidea Blandingii), Caitlin F. Copenhaver Mar 2024

A Dietary Variety: Analyzing The Impacts Of Diverse Vs Worm-Exclusive Diets On The Blanding’S Turtle (Emydoidea Blandingii), Caitlin F. Copenhaver

Honors Theses

The endangered Blanding’s turtle (Emydoidea blandingii) is a species with a generally diverse diet in their freshwater wetland habitats; they consume prey such as crayfish and snails. In captivity, these options often become more limited due to logistical reasons. As ex situ conservation efforts such as captive rearing and head-starting are becoming more popular for this species, it will be important to gain more insight on how these more limited diets might affect these turtles. This study describes a comparison between diets in six captive Blanding’s turtles from September to November of 2023, with three turtles receiving only …


Outclimbing Cognitive Decline: Age, Western Diet, Resistance Exercise, And The Brain., Leila Dzinic Feb 2024

Outclimbing Cognitive Decline: Age, Western Diet, Resistance Exercise, And The Brain., Leila Dzinic

Electronic Thesis and Dissertation Repository

Increased age and obesity diminish motivation, perseverance, and spatial memory function. Aerobic exercise interventions have successfully rescued some of these processes. However, in older and heavier populations aerobic exercise is not as sustainable due to high risk of injury. Resistance exercise consists of physical activity where maximum oxygen consumption is not increased and has been proposed as a safe and effective intervention for this population. Here, we used touchscreen-based cognitive testing to elucidate the influence of resistance exercise on motivation and spatial memory in aged, diet-induced obese mice, using a water restriction procedure I develop in Chapter 2. Mice underwent …

Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal Jan 2024

Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal

West Chester University Master’s Theses

Proposed regulations for alcohol advertising prevent beverage companies from targeting people under the legal drinking age. However, similar regulations for alcohol alternative beverages are less explored, which could allow alcohol alternative products to create awareness for alcoholic beverages among youth. Alcohol alternatives beverages, including no-alcohol and low-alcohol products, are increasing in popularity and can function as compliments to alcoholic products to decrease the total alcohol volume consumed or as substitutes for alcoholic products. Framing theory can be operationalized through the Content Appealing to Youth Index, an index of content elements found in research literature to be appealing to youth, to …


Estradiol’S Role In Timely Puberty Onset In The Ewe, Eliana Gerardine Aerts Jan 2024

Estradiol’S Role In Timely Puberty Onset In The Ewe, Eliana Gerardine Aerts

Graduate Theses, Dissertations, and Problem Reports

In female sheep, the release of gonadotropin-releasing hormone (GnRH) from the hypothalamus triggers luteinizing hormone (LH) to be released from the pituitary. Luteinizing hormone, in turn, acts on the ovaries to elicit estradiol (E2) release. E2 acts in a negative feedback manner to control the amount of LH released. The increase in LH release that drives puberty onset results from a decrease in sensitivity to E2 as the animal ages. However, the neural mechanisms mediating this change in sensitivity are not known, as is where in the hypothalamus E2-negative feedback occurs. In the arcuate …

The Impact Of Silage Inclusion In Diets With Different Corn Processing And The Effect Of Natural And Conventional Feeding Programs On Finishing Cattle Performance, Jessica L. Miller

Department of Animal Science: Dissertations, Theses, and Student Research

A finishing experiment was conducted to determine the effects of natural and conventional feeding programs on finishing performance of steers and heifers. Factors were conventional and natural feeding programs in steers and heifers. Cattle assigned to the conventional program were fed diets that contained Rumensin (Elanco Animal Health), Tylan (Elanco Animal Health), MGA (Zoetis), and received growth promoting implants whereas cattle in the natural program received neither. Compared to natural fed cattle, G:F was improved by 15.5% when heifers were fed in a conventional program (P < 0.01) and 23.8% when steers were fed in a conventional program (P < 0.01). The incorporation of implants and feed additives within the finishing period increased …


Factors Affecting Forage Quality And The Subsequent Response In Production And Energy Metabolism In Lactating Jersey Cows, Kassidy Kate Buse Dec 2023

Factors Affecting Forage Quality And The Subsequent Response In Production And Energy Metabolism In Lactating Jersey Cows, Kassidy Kate Buse

Department of Animal Science: Dissertations, Theses, and Student Research

Forage quality is the potential of a forage to produce a production response in animals. Because of how essential they are in dairy cattle rations, forages can have major influence on the behavior and production of dairy cattle. In experiment 1, the effect of forage fragility on the rumen environment and digestibility was evaluated. Increasing the inclusion of a less fragile forage led to greater rumen retention time, which resulted in lower rumen pH and greater NDF digestibility. Experiment 2 evaluated the effects of diets high in either corn silage or alfalfa haylage supplemented with either corn- or soybased protein …


Early-Life Supplementation Of Omega-3 Polyunsaturated Fatty Acids Improved Growth And Skeletal Muscle Glucose Metabolism In The Heat Stress-Induced Iugr Neonatal Lamb, Melanie Ryann White Dec 2023

Early-Life Supplementation Of Omega-3 Polyunsaturated Fatty Acids Improved Growth And Skeletal Muscle Glucose Metabolism In The Heat Stress-Induced Iugr Neonatal Lamb, Melanie Ryann White

Department of Animal Science: Dissertations, Theses, and Student Research

Our 1st study determined whether metabolic deficits of IUGR-born neonatal lambs can be improved by ameliorating elevated inflammatory tone. Supplementation with ω-3 polyunsaturated fatty acids (ω-3 PUFA) improved hindlimb insulin-stimulated glucose oxidation rates and basal lactate secretion. Ex vivo skeletal muscle-specific glucose oxidation rates were improved when heightened inflammatory tone was moderated. Pancreatic β cell function in response to hyperglycemia was improved by ω-3 PUFA supplementation. Tempered inflammatory tone also partially recovered skeletal muscle glycogen stores. Thus, we found that targeting heightened inflammatory tone inherent in IUGR-born neonatal lambs moderately improved glucose metabolism and pancreatic β cell …


Milk-Borne Small Extracellular Vesicles: Kinetics And Mechanisms Of Transport, Distribution, And Elimination, Alice Ngu, Javaria Munir, Janos Zempleni Oct 2023

Milk-Borne Small Extracellular Vesicles: Kinetics And Mechanisms Of Transport, Distribution, And Elimination, Alice Ngu, Javaria Munir, Janos Zempleni

Department of Nutrition and Health Sciences: Faculty Publications

Small extracellular vesicles (sEVs) in milk have the qualities desired for delivering therapeutics to diseased tissues. The production of bovine milk sEVs is scalable (1021 annually per cow), and they resist degradation in the gastrointestinal tract. Most cells studied to date internalize milk sEVs by a saturable process that follows Michaelis-Menten kinetics. The bioavailability of oral milk sEVs is approximately 50%. In addition to crossing the intestinal mucosa, milk sEVs also cross barriers such as the placenta and blood-brain barrier, thereby enabling the delivery of therapeutics to hard-to-reach tissues. In time course studies, levels of milk sEVs peaked in …

Although several reports have hypothesized that exercise may increase skeletal muscle protein lactylation, empirical evidence in humans is lacking. Thus, we adopted a multifaceted approach to examine if acute and subchronic resistance training (RT) altered skeletal muscle protein lactylation levels. In mice, we also sought to examine if surgical ablation-induced plantaris hypertrophy coincided with increases in muscle protein lactylation. To examine acute responses, participants’ blood lactate concentrations were assessed before, during, and after eight sets of an exhaustive lower body RT bout (n = 10 trained college-aged men). Vastus lateralis biopsies were also taken before, 3-h post, and 6-h post-exercise …
