Faculty, Staff and Student Publications

This study aimed to determine what conditions were needed to reduce the production of acrylamide when balloon flower roots [Platycodon grandiflorum (Jacq. A. DC.)] were heated. The conditions of temperature, time, and the type of equipment (i.e., consumer appliance or industrial equipment) were the important variables in the experiment. The official criterion for a recommended standard of acrylamide in tea product is less than 1000 µg/kg as determined by the Ministry of Food and Drug Safety in South Korea. A response surface methodology was used to determine whether the heated samples met the safety requirements. The most significant condition …

Prematurity Blunts Protein Synthesis In Skeletal Muscle Independently Of Body Weight In Neonatal Pigs, Marko Rudar, Jane K Naberhuis, Agus Suryawan, Hanh V Nguyen, Marta L Fiorotto, Teresa A Davis

Faculty, Staff and Students Publications

Background

Postnatal growth failure in premature infants is associated with reduced lean mass accretion. Prematurity impairs the feeding-induced stimulation of translation initiation and protein synthesis in the skeletal muscle of neonatal pigs. The objective was to determine whether body weight independently contributes to the blunted postprandial protein synthesis.

Methods

Preterm and term pigs that were either fasted or fed were stratified into quartiles according to birth weight to yield preterm and term groups of similar body weight; first and second quartiles of preterm pigs and third and fourth quartiles of term pigs were compared (preterm-fasted, n = 23; preterm-fed, n …

Distinct Gene Expression Profiles Between Human Preterm-Derived And Adult-Derived Intestinal Organoids Exposed To Enterococcus Faecalis: A Pilot Study, Andrea C. Masi, Tatiana Y.

We read with interest the study by Kayisoglu et al¹ comparing the gene expression between embryo-derived and adult-derived intestinal organoids. Some innate immune system genes were differentially expressed between the two organoid types, suggesting a potential role of exposure to the environment, including gut microbiota, in shaping the intestinal gene expression. In extremely preterm infants (<32 weeks gestation), microbial–host interaction at the epithelial surface has been associated with various morbidities including late onset sepsis and necrotising enterocolitis.² Thus, preterm intestinal organoids may provide a specific and robust model for this population.

Dietary Sources Of Linoleic Acid (La) Differ By Race/Ethnicity In Adults Participating In The National Health And Nutrition Examination Survey (Nhanes) Between 2017-2018, Shabnam R Momin, Mackenzie K Senn, Ani Manichaikul, Chaojie Yang, Rasika Mathias, Mimi Phan, Stephen S Rich, Susan Sergeant, Michael Seeds, Lindsay Reynolds, Floyd H Chilton, Alexis C Wood

Faculty, Staff and Students Publications

Linoleic acid (LA) is a primary n-6 polyunsaturated fatty acid (PUFA), which is of interest to nutritional professionals as it has been associated with health outcomes. However, as some LA-rich foods offer protection against chronic diseases such as CVD (e.g., fatty fish), while others increase risk (e.g., red meat), the individual foods contributing to LA intake may be an important factor to consider. Therefore, this analysis sought to examine whether there are racial/ethnic differences in the proportion of overall LA intake accounted for by individual food groups, via a cross-sectional analysis of 3815 adults participating in the National Health …

Determining The Existence And Regulation Of Microlipophagy In Primary Brown And White Adipocytes, Sara C. Arenas De Leon

Biomedical Sciences ETDs

Lipids are one of life’s four main macromolecules and provide essential functions to cells, as they serve as building blocks of cellular membranes, mediate cell signaling, and are a critical energy source. Within cells, esterified fatty acids aggregate into lipid droplets in the form of triglycerides, consisting of a neutral lipid core surrounded by a phospholipid monolayer decorated with various proteins.

The degradation of lipid droplets and mobilization of lipids occurs through lipolysis, a process that hydrolyzes a molecule of triglyceride into a glycerol and three fatty acids. Emerging evidence demonstrates the involvement of a selective form of autophagy in …

The Effect Of Adding Mango To A Breakfast Meal On Glycemic And Satiety Responses And Next Meal Energy Consumption, Natalie R. Ramos

Master's Theses

Spikes in blood glucose (BG) result in adverse health consequences in people with and without diabetes. This study aimed to compare the BG and satiety responses of adding mango or sugar to a high glycemic load (HGL) breakfast. A randomized, controlled trial (cross-over design) was conducted with 18 participants. Participants consumed cornflakes and almond milk (Control), control plus 34gm added sugar (ASug), or added mango (AMango) with 34gm carbohydrate. BG was determined at fasting, 15, 30, 60, 90, 120min postprandial; satiety was rated with a visual analog scale at each time point. At 120min, subjects consumed a snack of hummus …

Research outputs 2022 to 2026

We aimed to compare the dietary intakes of Australian patients with non-alcoholic fatty liver disease (NAFLD) to general Australian population intake data and determine whether the intake of any nutrient or food group was able to predict the degree of steatosis. Dietary data from fifty adult patients with NAFLD were compared to intake data from the Australian Health Survey for energy, macronutrients, fat sub-types, alcohol, iron, folate, sugar, fibre, sodium and caffeine. Linear regression models adjusting for potential confounders (age, sex, physical activity and body mass index) were used to examine predictive relationships between hepatic steatosis (quantified via magnetic resonance …

Birth Weight Moderates The Association Between Obesity And Mortality Rate, Gregory Pavela, Nengjun Yi, Luis Mestre, Pengcheng Xun, David B Allison

Children’s Nutrition Research Center Staff Publications

Purpose: The strength of the association between obesity and mortality rate (MR) varies by body mass index (BMI) and sociodemographic groups. We test the hypothesis that the association between obesity and MR varies, in part, due to the moderating effect of parental BMI and birth weight.

Methods: Data come from the 1958 National Child Development Study, an ongoing longitudinal dataset initiated in 1958 with baseline measures of birth weight from 18,059 infants born in Great Britain over 1 week. We tested whether the association between BMI and MR was moderated by parental BMI and birth weight using generalized additive proportional …

Preterm Birth Alters The Feeding-Induced Activation Of Akt Signaling In The Muscle Of Neonatal Piglets, Agus Suryawan, Marko Rudar, Jane K Naberhuis, Marta L Fiorotto, Teresa A Davis

Faculty, Staff and Students Publications

BACKGROUND: Postnatal lean mass accretion is commonly reduced in preterm infants. This study investigated mechanisms involved in the blunted feeding-induced activation of Akt in the skeletal muscle of preterm pigs that contributes to lower protein synthesis rates.

METHODS: On day 3 following cesarean section, preterm and term piglets were fasted or fed an enteral meal. Activation of Akt signaling pathways in skeletal muscle was determined.

RESULTS: Akt1 and Akt2, but not Akt3, phosphorylation were lower in the skeletal muscle of preterm than in term pigs (P < 0.05). Activation of Akt-positive regulators, PDK1 and mTORC2, but not FAK, were lower in preterm than in term (P < 0.05). The formation of Akt complexes with GAPDH and Hsp90 and the abundance of Ubl4A were lower in preterm than in term (P < 0.05). The abundance of Akt inhibitors, PHLPP and SHIP2, but not PTEN and IP6K1, were higher in preterm than in term pigs (P < 0.05). PP2A activation was inhibited by feeding in term but not in preterm pigs (P < 0.05).

CONCLUSIONS: Our results suggest that preterm birth impairs regulatory components involved in Akt activation, …

Lateral Septum As A Melanocortin Downstream Site In Obesity Development, Yuanzhong Xu, Zhiying Jiang, Hongli Li, Jing Cai, Yanyan Jiang, Joshua Otiz-Guzman, Yong Xu, Benjamin R Arenkiel, Qingchun Tong

Faculty, Staff and Students Publications

The melanocortin pathway is well established to be critical for body-weight regulation in both rodents and humans. Despite extensive studies focusing on this pathway, the downstream brain sites that mediate its action are not clear. Here, we found that, among the known paraventricular hypothalamic (PVH) neuron groups, those expressing melanocortin receptors 4 (PVHMc4R) preferably project to the ventral part of the lateral septum (LSv), a brain region known to be involved in emotional behaviors. Photostimulation of PVHMc4R neuron terminals in the LSv reduces feeding and causes aversion, whereas deletion of Mc4Rs or disruption of glutamate release from LSv-projecting PVH neurons …
