Makara Journal of Science

Lemongrass is a common ingredient in Indonesian traditional herbal medicine that potently inhibits carbohydrate hydrolysis. In this study, the in vitro α-glucosidase inhibitory (AGI) activity of lemongrass was compared with its in vivo activity to retard postprandial blood glucose elevation, and the bioactive compounds responsible for these activities were observed. Both water and ethanolic extracts of lemongrass (WLG and ELG, respectively) were tested in vitro for its inhibition of the sucrose and maltose hydrolyzing activities of rat intestinal glucosidase. ELG was observed to exert higher inhibitory activities (Sucrase IC₅₀ = 8.74 mg/mL; Maltase IC₅₀ = 18.93 mg/mL) than …

A Crisis Of Kelp, Rachel L. Sherman

Capstones

Along with insects and lab-grown meat, for years seaweed has been lauded as a sustainable “food of the future” by the U.N. Food and Agricultural Organization. As the world increasingly turns to alternative foods in pursuit of a healthier Earth, seaweed has all the makings of an ecological savior. It’s plentiful — seaweeds and ocean algae make up roughly nine tenths of all the plant life on Earth — it’s cheap to harvest and get to market, packed with nutrition, and keeps oceans clean, absorbing more carbon dioxide and releasing more oxygen than the world’s rainforests.

But outside of Japanese …

Aligning Food Environments With Institutional Values: A Mixed Methods Study Of Oregon Health Care Organizations, Elizaveta Walker

Dissertations and Theses

A major driver of the obesity epidemic is obesogenic food environments, characterized by nutrient-poor and energy-dense foods that saturate the collective physical, economic and sociocultural conditions that influence nutritional status. Food environments in organizations such as hospitals and public health agencies warrant special consideration given their health-focused mission. Improving food environments within health care settings has been highlighted by the Centers for Disease Control and Prevention (CDC) as one of seven key strategies to prevent obesity. However, most of the refereed literature examining healthy food environment policies (HFEPs) within hospitals focuses on the inpatient dietary environment, leaving a paucity of …

Horizontal Genetic Exchange Of Chromosomally Encoded Markers Between Campylobacter Jejuni Cells, Deepti Pranay Samarth, Young Min Kwon

Poultry Science Faculty Publications and Presentations

Many epidemiological studies provide us with the evidence of horizontal gene transfer (HGT) contributing to the bacterial genomic diversity that benefits the bacterial populations with increased ability to adapt to the dynamic environments. Campylobacter jejuni, a major cause of acute enteritis in the U.S., often linked with severe post-infection neuropathies, has been reported to exhibit a non-clonal population structure and comparatively higher strain-level genetic variation. In this study, we provide evidence of the HGT of chromosomally encoded genetic markers between C. jejuni cells in the biphasic MH medium. We used two C. jejuni NCTC-11168 mutants harbouring distinct …

Homicide And Drug Trafficking In Impoverished Communities In Brazil, Elenice De Souza Oliveira, Braulio Figueiredo Alves Da Silva, Flavio Luiz Sapori, Gabriela Gomes Cardoso

Department of Justice Studies Faculty Scholarship and Creative Works

Many studies demonstrate that homicides are heavily concentrated in impoverished neighborhoods, but not all socially disadvantaged neighborhoods are hotbeds of violence. Conducted in Belo Horizonte, Brazil, this study hypothesizes that the association between high rates of homicide and impoverished areas is influenced by the emergence of a specific type of street drug-dealing common to favelas (slums). The study applies econometric techniques to police data on homicides and drug arrests from 2008 to 2011, as well as 2010 Census data, to test its hypothesis. The findings provide insight into the development of crime prevention policies in areas of high social vulnerability.

Nutrition, Dietetics, and Food Sciences Faculty Publications

The effect of caseinomacropeptide (CMP) on the heat-induced denaturation and gelation of whey proteins (2.5–10%, w/v) at pH 6.4 and 7.2, at a whey protein:CMP ratio of 1:0.9 (w/w), was investigated using differential scanning calorimetry (DSC), oscillatory rheology (90 °C for 20 min) and confocal microscopy. Greater frequency-dependence in the presence of CMP suggested that the repulsive interactions between CMP and the whey proteins affected the network generated by the non-heated whey protein samples. At pH 6.4 or 7.2, CMP increased the temperature of denaturation of β-lactoglobulin by up to 3 °C and increased the gelation temperature by up to …

Solubility Of Carbon Dioxide In Renneted Casein Matrices: Effect Of Ph, Salt, Temperature, Partial Pressure, And Moisture To Protein Ratio, Prabin Lamichhane, Prateek Sharma, Alan L. Kelly, Jens Risbo, Fergal P. Rattray, Jeremiah J. Sheehan

Nutrition, Dietetics, and Food Sciences Faculty Publications

The solubility of carbon dioxide (CO2) in the moisture and protein components of cheese matrices and the influence of changing pH, salt and temperature levels remains unclear. In this study, model casein matrices were prepared, by renneting of micellar casein concentrate (MCC), with modulation of salt and pH levels by adding salt and glucono delta-lactone, respectively, to the MCC solutions prior to renneting. Different moisture-to-protein levels were achieved by freeze-drying, incubation of samples at different relative humidities, or by applying varying pressures during gel manufacture. The CO2 solubility of samples decreased linearly with both increasing temperature and salt-in-moisture content, whereas …

Food Safety Risk In An Indoor Microgreen Cultivation System, Gina Marie Misra

Graduate Theses and Dissertations

Microgreens are immature sprouts of edible plants, sharing some similarities with sprouted seeds and petite leafy greens. Since they are most often grown in containers in buildings or greenhouses, they present a new area for food safety research at the intersection of the built environment and produce farming. Contamination by human pathogens has been extensively studied in other types of produce typically eaten raw, including sprouted seeds, which have been implicated in numerous outbreaks of salmonellosis over the last several decades. There is a paucity of knowledge about the microgreen sector of the fresh-cut industry; thus, it was determined that …

The Role Of Diet In The Onset Of Depression: A Biochemical Connection Between Nutrition And Mental Health, Katlin Wildeman

Senior Honors Theses

Depression is a major clinical concern, having a complex onset and the presence of multiple, often unidentifiable causes. Depression affects millions of individuals worldwide, with a high prevalence in regions of the world with a Western-style diet as compared to regions with a Mediterranean diet. A Western-style diet consists of foods high in sugar, fat, and processed meats and grains, whereas the Mediterranean diet contains significantly more vegetables, fruits, lean meats, and whole grains. The link between diet and mental health disorders has implications for individuals of all ages who are hesitant to turn to medication. In addition to presenting …

Structure And Stability Of W1/O/W2 Emulsions As Influenced By Wpc And Nacl In Inner Aqueous Phase, Vivek Prakash Wankhede, Prateek Sharma, Shaik Abdul Hussain, Ram Ran Bijoy Singh

Nutrition, Dietetics, and Food Sciences Faculty Publications

Effect of WPC and NaCl in internal aqueous phase (W1) of W1/O/W2 type double emulsions was studied. Pre-emulsion and final emulsion were prepared using microfluidizer and Ultra-Turrax high shear mixer, respectively. The emulsions prepared using salt exhibited uniform droplet size distribution and structural integrity. WPC at 6% and NaCl at 2 or 4% levels demonstrated better sedimentation stability (> 99%) and encapsulation stability (> 95%) during preparation and storage of double emulsions. Samples without added NaCl showed poor emulsion stability and structural integrity. Higher level of WPC i.e. 8% resulted in poor stability and encapsulation efficiency of double emulsions at …

Stunting And Infectious Disease In Ethiopian And Zambian Children, Alyssa Arndt

NUTR/GLST 498b: Global Research Experiences in Nutrition and Health

PURPOSE: To evaluate whether children who are malnourished/stunted are more likely to have experienced infectious disease.

METHODS: 6th and 7th students (n=546) were interviewed about health history and assessed using anthropometry.

RESULTS: Children who are short for their age also have higher rates of stunting. Malaria is the most experienced infectious disease.

CONCLUSIONS: Given that malaria was the most common infectious disease experience listed among middle school children, and that those who have experienced disease are more likely to be stunted, increased malaria prevention methods may improve the long-term health of Ethiopian and Zambian schoolchildren.

Comparisons Of Celiac Disease And Non-Celiac Gluten Sensitivity, Victoria Thomas

Senior Honors Theses

Celiac disease (CD) and non-celiac gluten sensitivity (NCGS) are often confused or grouped together due to their commonalities. However, this is careless behavior because there are clinically significant differences between the two diseases. Similarities between them include varying degrees of damage or permeability in the lining of the small intestine, involvement of the innate immune system, alleviation of symptoms upon implementation of a gluten-free diet (GFD), and the possibility for complications if the pathology is not adequately treated. Despite these similarities, minor details such as the following make CD and NCGS worth differentiating: the question of gluten as the true …
