Anti-Inflammatory Effect Of Apiaceous Vegetables In A Mouse Model Of Colitis - Implications For Colon Cancer Risk, Laura Mariana Mariana Echavarri Ibarra

Graduate Theses and Dissertations

Colorectal cancer is the second leading cause of cancer-related deaths in the US. Dietary habits account for 50% of the cases. A westernized diet (high fat, high sugar/fructose, and low in fruits and vegetables) and inflammatory bowel diseases are risk factors for colorectal cancer. Evidence suggests phytochemicals in apiaceous vegetables (API; celery family) possess anti-inflammatory and potentially chemopreventive properties. Hence, investigation of whether the consumption of API mitigates acute colitis is warranted. Using mice fed the Total Western Diet (TWD) and administered dextran sodium sulfate (DSS; induces colitis), the objectives of this project are to identify the effects of API …

Phenotypic And Transcriptomic Characterization Of Rice Snrk1 Mutants Developed By Crispr/Cas9 Mutagenesis, Maria Clara Faria Chaves

Graduate Theses and Dissertations

SnRK1 is a heterotrimeric protein kinase that is composed of a catalytic subunit (α) and two regulatory subunits (β and βγ), and it has a main role in regulating energy homeostasis in the plant by modulating anabolic and catabolic process. SnRK1 phosphorylates and alters the activities of enzymes involved in metabolism and regulates gene expression by altering the activity of chromatin-remodeling enzymes or the transcription factors. Rice contains three functional paralogs of SnRK1α: SnRK1αa (LOC_Os03g17980), SnRK1αb (LOC_Os08g37800), and SnRK1αc (LOC_Os05g45420). This study focused on the function of these SnRK1 paralogs by evaluating the phenotypic and transcriptomic characteristics and the disease …

Generating Health-Promoting Bioactive Compounds And Nanoporous Materials From Rice Processing Byproducts Via Supercritical Carbon Dioxide Technology, Sumanjot Kaur

No Strong Evidence Of The Protein Leverage Hypothesis In Pregnant Women With Obesity And Their Infants, Maryam Kebbe, Jasper Most, Abby D. Altazan, Leanne M. Redman

Clinical Research Faculty Publications

Objective: The goal of this study was to investigate the role of dietary protein on macronutrient and energy intake, maternal adiposity during pregnancy, and infant adiposity at birth. Methods: In 41 women with obesity, early-pregnancy (13–16 weeks) protein intake was assessed with food photography and expressed as a ratio of Estimated Average Requirements (EAR) in pregnancy for protein (0.88 g/kg/d), herein “protein balance.” Energy intake was measured by the intake-balance method, gestational weight gain as grams per week, and fat mass by a three-compartment model. Spearman correlations and linear models were computed using R version 4.1.1 (p < 0.05 considered significant). Results: Women had a mean (SD) age of 27.5 (4.8) years and a pregravid BMI of 34.4 (2.9), kg/m2, and the majority were non-White (n = 23, 56.1%). Protein balance in early pregnancy was not significantly associated with energy intake across mid and mid/late pregnancy (β = 328.7, p = 0.30 and β = 286.2, p = 0.26, respectively) or gestational weight gain (β = 117.0, p = 0.41). Protein balance was inversely associated with fat mass in early, mid, and late pregnancy (β = −10.6, p = 0.01, β = −10.4, p = 0.03, β = −10.3, p = 0.03, respectively). Protein balance did not predict infant adiposity at birth (p > 0.05). Conclusions: Low …

Investigating And Characterizing Septin Cellular Regulators During Infection Related Development In M. Oryzae, Rinalda Proko

Graduate Theses and Dissertations

The fungus Magnaporthe oryzae causes a devastating disease of rice and wheat, called blast, which poses a major threat to food security across the planet. To enter plant tissue, M. oryzae produces a remarkable pressure-generating infection cell called an appressorium, which mechanically ruptures the tough cuticle of host leaves through the application of enormous physical force directed onto a narrow penetration structure emerging from its base. Importantly, appressorium form and functionality depends on the regulated assembly of a toroidal ring-like structure, composed of septins, which forms within its base. Septins are a family of membrane-associated GTP-binding proteins that polymerize into …

Obstetrics and Gynaecology, East Africa

Background: Postnatal depression (PND) is associated with adverse infant neurodevelopmental outcomes. Evidence is limited on how PND influences neonatal (<28 days old) outcomes in low- and middle-income countries, such as Kenya, which bear the global burden of neonatal morbidity and mortality.

Objectives: To explore how PND influences neonatal feeding and care practices among women in the early postnatal period in rural Western Kenya.

Design: A cross-sectional study.

Methods: Semi-structured interviews were conducted at 2-weeks postpartum among mothers of newborn infants identified <72 h old from the postnatal wards and clinics across five health facilities in Kisumu County of Western Kenya. They were all screened for features suggestive of postnatal depression using the Edinburgh Postnatal Depression Scale.

Results: Twenty-four mothers were interviewed, 13 of whom had features suggestive of PND. All mothers experienced health or socio-economic adversities in the perinatal period, including traumatic deliveries, financial constraints, and challenging relationships with partners/other family members. Feeding difficulties due to …

Effects Of Circadian Rhythm Disruption And Social Jetlag On The Cardiometabolic Adaptations To Exercise, Michael Bevan Dial

UNLV Theses, Dissertations, Professional Papers, and Capstones

Circadian rhythms lie within every tissue and cell and regulate cellular and tissue processes and functions based upon the time of day. Disrupting the circadian clock results in impaired tissue and organ activity and higher risk of cardiometabolic diseases. A common form of circadian rhythm disruption is social jetlag (SJL), which represents the misalignment of sleep and wake times on free days and work days (i.e. weekend). The time of day of exercise affects the adaptations that are derived from exercise. Within the heart muscle, disparate levels of exercise-induced hypertrophy, circadian clock gene expression, and mitochondrial content were all dependent …

The Influence Of Concussion History And Head Acceleration On Lower Extremity Function, Warren Forbes

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sport-related concussions (SRCs) play a very debilitative role in athletics with between 1.7 – 3 million SRCs occurring annually (Clay et al., 2013; Zuckerman et al., 2015). This equates to upwards of 21.5 SRCs per 1000 athletic exposures. Research pertaining to SRC has received intense focus because of the substantial financial impact on the US healthcare system as well as the negative impact that SRCs have on the quality of life of athletes. Much of the research concerning SRC has been centered around management and ensuring adequate recovery from SRC-related symptoms. The current return to play (RTP) criteria from an …

Exogenous Exposure To Dihydroxyacetone Mimics High Fructose Induced Oxidative Stress And Mitochondrial Dysfunction, Raj Mehta

Honors Theses

Dihydroxyacetone (DHA) is a three-carbon sugar that is the active ingredient in sunless tanning products and a by-product of electronic cigarette (e-cigarette) combustion. Increased use of sunless tanning products and e-cigarettes has elevated exposures to DHA through inhalation and absorption. Studies have confirmed that DHA is rapidly absorbed into cells and can enter into metabolic pathways following phosphorylation to dihydroxyacetone phosphate (DHAP), a product of fructose metabolism. Recent reports have suggested metabolic imbalance and cellular stress results from DHA exposures. However, the impact of elevated exposure to DHA on human health is currently under-investigated. We propose that exogenous exposures to …
