Children’s Nutrition Research Center Staff Publications

The current obesity epidemic mainly results from high-fat high-caloric diet (HFD) feeding and may also be contributed by chronic stress; however, the neural basis underlying stress-related diet-induced obesity remains unknown. Corticotropin-releasing hormone (CRH) neurons in the paraventricular hypothalamus (PVH), a known body weight-regulating region, represent one key group of stress-responsive neurons. Here, we found that HFD feeding blunted PVH CRH neuron response to nutritional challenges as well as stress stimuli and dexamethesone, which normally produce rapid activation and inhibition on these neurons, respectively. We generated mouse models with the activity of these neurons clamped at high or low levels, both …

Application Of A Cascade Membrane Filtration Process To Standardise Serum Protein Depleted Cheese Milk For Cheddar Cheese Manufacture, Xiaofeng Xia, John B. Tobin, Prateek Sharma, Mark Fenelon, Paul L.H. Mcsweeney, Jeremiah J. Sheehan

Nutrition, Dietetics, and Food Sciences Faculty Publications

A cascade membrane filtration process including microfiltration (MF), ultrafiltration (UF) and reverse osmosis (RO) was used to fractionate skim milk into different streams. Significant quantities of lactose and minerals were removed to permeate after MF at 0.14 μm. Cheese milk, of similar casein content to the raw milk, was standardised simultaneously for casein, lactose, ash and total calcium from the membrane streams without requiring CaCl2 and lactose addition. Serum protein depleted cheese milk of typical casein content had similar rennet coagulability, cheese composition, texture and yield to the control; milk of 1.5 × casein content had a faster coagulation rate …

Multi-component lipid emulsions, rather than soy-oil emulsions, prevent cholestasis by an unknown mechanism. Here, we quantified liver function, bile acid pools, and gut microbial and metabolite profiles in premature parenterally fed pigs given a soy-oil lipid emulsion, Intralipid (IL), a multi component lipid emulsion, SMOFlipid (SMOF), a novel emulsion with a modified fatty-acid composition [experimental emulsion (EXP)], or a control enteral diet (ENT) for 22 days. We assayed serum cholestasis markers, measured total bile acid levels in plasma, liver, and gut contents, and analyzed colonic bacterial 16S rRNA gene sequences and metabolomic profiles. Serum cholestasis markers (i.e., bilirubin, bile acids, …

The Consequences Of Exercise-Induced Weight Loss On Food Reinforcement. A Randomized Controlled Trial, Kyle D. Flack, Harry M. Hays, Jack Moreland

Dietetics and Human Nutrition Faculty Publications

BACKGROUND: Obesity remains a primary threat to the health of most Americans, with over 66% considered overweight or obese with a body mass index (BMI) of 25 kg/m2 or greater. A common treatment option many believe to be effective, and therefore turn to, is exercise. However, the amount of weight loss from exercise training is often disappointingly less than expected with greater amounts of exercise not always promoting greater weight loss. Increases in energy intake have been prescribed as the primary reason for this lack of weight loss success with exercise. Research has mostly focused on alterations in hormonal mediators …

Teachers’ Perceptions And Understanding Of Children’S Fluid Intake, Kristy Howells, Tara Coppinger

Publications

No public health data exists on elementary teachers’ perceptions of both their own fluid intake and of their elementary school aged children’s fluid intake. A total of 271 (20 males, 251 females) teachers in developed areas of Australia, Belgium, England, Ireland, United Arab Emirates, and the United States of America completed an online questionnaire (Feb–Mar 2019) on: (i) their fluid intake, (ii) their perception and understanding of children’s fluid intake and (iii) barriers in the school day that they felt prevented school children consuming fluids. Overall, the data indicated that teachers consume considerably lower amounts than recommended themselves, but have …

Alteration Of Iron Responsive Gene Expression In Arabidopsis Glutaredoxin S17 Loss Of Function Plants With Or Without Iron Stress, Ninghui Cheng, Han Yu, Xiaolan Rao, Sunghun Park, Erin L Connolly, Kendal D Hirschi, Paul A Nakata

Children’s Nutrition Research Center Staff Publications

Iron (Fe) is a mineral nutrient and a metal cofactor essential for plants. Iron limitation can have detrimental effects on plant growth and development, while excess iron inside plant cells leads to oxidative damage. As a result, plants have evolved complex regulatory networks to respond to fluctuations in cellular iron concentrations. The mechanisms that regulate these responses however, are not fully understood. Heterologous expression of an Arabidopsis thaliana monothiol glutaredoxin S17 (GRXS17) suppresses the over-accumulation of iron in the Saccharomyces cerevisiae Grx3/Grx4 mutant and disruption of GRXS17 causes plant sensitivity to exogenous oxidants and iron deficiency stress. GRXS17 may act …

Do Physicians Perceive The Roles Of Nutritionists And Registered Dietitian Nutritionists As Different?, William Ramirez, Megan Williams

Loma Linda University Research Reports

Background: Dietitians are still divided on whether to use the credential Registered Dietitian (RD) or Registered Dietitian Nutritionist (RDN). The option for dietitians to utilize RDN gained support in a 2013 joint committee meeting. The ambiguity between the terms dietitian and nutritionist leave many individuals unable to discern between the two. The opportunity for dietitians to treat greater quantities of patients is influenced by physicians’ understanding of dietitians’ roles and the public's understanding of services they provide.

Objective: To determine how the terms dietitian and nutritionist are understood and referred to in the healthcare setting and whether RD …

The Trait Repertoire Enabling Cyanobacteria To Bloom Assessed Through Comparative Genomic Complexity And Metatranscriptomics, Huansheng Cao, Yohei Shimura, Morgan M. Steffen, Zhou Yang, Jingrang Lu, Allen Joel, Landon Jenkins, Masanobu Kawachi, Yanbin Yin, Ferran Garcia-Pichel

Food for Health: Publications

Water bloom development due to eutrophication constitutes a case of niche specialization among planktonic cyanobacteria, but the genomic repertoire allowing bloom formation in only some species has not been fully characterized. We posited that the habitat relevance of a trait begets its underlying genomic complexity, so that traits within the repertoire would be differentially more complex in species successfully thriving in that habitat than in close species that cannot. To test this for the case of bloom-forming cyanobacteria, we curated 17 potentially relevant query metabolic pathways and five core pathways selected according to existing ecophysiological literature. The available 113 genomes …

How Does Ginsenoside Rh2 Mitigate Adipogenesis In Cultured Cells And Obese Mice?, Longyun Zhang, Carlos Virgous, Hongwei Si

Human Sciences Faculty Research

Ginsenoside Rh2, an intermediate metabolite of ginseng, but not naturally occurring, has recently drawn attention because of its anticancer effect. However, it is not clear if and how Rh2 inhibits preadipocytes differentiation. In the present study, we hypothesized that ginsenoside Rh2 attenuates adipogenesis through regulating the peroxisome proliferator-activated receptor gamma (PPAR-γ) pathway both in cells and obese mice. Different concentrations of Rh2 were applied both in 3T3-L1 cells and human primary preadipocytes to determine if Rh2 inhibits cell differentiation. Dietary Rh2 was administered to obese mice to determine if Rh2 prevents obesity in vivo. The mRNA and protein expression of …

Neuroprotection Against Alzheimer’S And Lifespan Extension Induced By Dietary Restriction Are Associated With Metabolomic Changes And Depend On Oxidative Resistance Protein 1 (Oxr1), George W. Brownridge Iii

Natural Sciences and Mathematics | Biological Sciences Master's Theses

Dietary restriction (DR) has been demonstrated to be a robust means of extending the healthspan and lifespan, along with improving cognitive performance in various model organisms from yeast to primates, possibly by mediating neuroprotection. We utilized the Drosophila melanogaster model organism to better understand the molecular pathways that enable DR-induced benefits. By performing a genome-wide associated screening of the Drosophila Genetic Reference Panel (DGRP) that catalogues all natural genetic variants, we discovered that Oxidative resistance protein 1 (OXR1) showed the most significant difference in expression between DR and the inverse intervention of ad libitum (AL). Our research found that OXR1 …
