Compressed Dna Representation For Efficient Amr Classification, John Partee, Robert Hazell, Anjli Solsi, John Santerre

SMU Data Science Review

In this paper, we explore a representation methodology for the compression of DNA isolates. Using lossless string compression via tokenization of frequently repeated segments of DNA, we reduce the length of the isolates to be counted as k-mers for classification. With this new representation, we apply a previously established feature sampling method to dramatically reduce the feature space. In understanding the genetic diversity, we also look at conserving biological function across these spaces. Using a random forest model we were able to predict the resistance or susceptibility of bacteria with 85-90\% accuracy, with a 30-50\% reduction in overall isolate length, …

Animal and Food Sciences Faculty Publications

The increasing concern for food safety has created a need to evaluate novel techniques to eliminate or control pathogens, resulting in safe food. In this study, four bacteriophages of bovine origin, specific to E. coli O157:H7, were successfully isolated and characterized. A microplate reader assay demonstrated the efficacy of the bacteriophage (phage) cocktail against E. coli O157:H7 resulting in a significant reduction (p < 0.01) in the target pathogen population. The phage cocktail demonstrated significant efficacy (p < 0.05) against E. coli O157:H7 in the presence of the most utilized sanitizers in the United States, namely 100 parts per million (ppm) free chlorine and 100-ppm peroxyacetic acid. Survival in the sanitizer concentrations demonstrates the potential …

Detection Of Melamine Based On The Suppressed Anodic Response Of Uric Acid By A Au-Ag Nanoparticles Modified Glassy Carbon Electrode, Yu-Hui Peng, Tsunghsueh Wu, Yang-Wei Lin

Journal of Food and Drug Analysis

We demonstrated a sensitive electrochemical method for the determination of non-electroactive melamine (Mel) using a modified glassy carbon electrode (GCE), with uric acid (UA) as the signal reporter. To increase the anodic response of UA, GCE was coated with Au–Ag nanoparticles and a Nafion thin film (Au–Ag/Nafion/GCE). The sensing mechanism was based on the competitive adsorption behavior of Mel on the Au–Ag/Nafion/GCE, which reduces the electroactive surface area of nanoparticles and thus hinders anodic response of UA. Under optimal conditions and the use of an analytical method of differential pulse voltammetry, this modified electrode detected Mel concentrations ranging from 2.5 …

Journal of Food and Drug Analysis

Hyperthyroidism is a common endocrine disorder associated with increased risk of cardiovascular complications and mortality. Although antithyroid drugs (ATDs) are approved as first line option for many hyperthyroidism cases, including pregnancy and childhood, they exert significant toxic profile. Medicago sativa L. (alfalfa) also called “The father of all food” was among the diet consumed by mares that gave birth to foals with congenital hypothyroidism. Since, greenfeed was accused for the development of such condition, alfalfa may possess constituents with promising antithyroid potential that could be a valuable substitute for the conventional ATDs. The current work was designed to identify the …

In this study, a specific polyclonal antibody against PD (PD–pAb) was developed, and PD–pAb-based indirect competitive enzyme-linked immunosorbent assay (icELISA) was established for the detection of PD in Radix Platycodonis. The 50% inhibition concentration (IC₅₀) of PD was 2.70 μg/mL and the linearity range for PD was from 0.064 μg/mL to 100 μg/mL. No cross reactivity with PD–pAb was found in five PD analogs except for PD2 (0.93%). The average recovery of PD by icELISA was …

Spatiotemporal Patterns Of Polychlorinated Dibenzo-P-Dioxins And Dibenzofurans And Dioxin-Like Polychlorinated Biphenyls In Foodstuffs In Air Quality Regions In Taiwan, Ching-Chang Lee, Wei-Hsiang Chang, Hsin-Tang Lin, Jung-Wei Chang

Journal of Food and Drug Analysis

High-fat food intake is the main source of dioxin-like compounds for humans, such as consumption of meat, dairy and eggs, and seafood products. Fruits, vegetables, and cereals have relatively low levels of dioxin-like compounds, but because of high consumption they also contribute to the food-borne intake. It is necessary to clarify dietary dioxin exposure affected by different food contamination levels and dietary habits among different geographic areas. We aimed to evaluate chronic dietary PCDD/Fs and DL-PCBs exposure in 725 individual foods in 14 categories in 6 Taiwan air quality regions (AQRs) and a total of 2,441 foods from 2004 and …

Lipophilized Epigallocatechin (Egc) And Its Derivatives: Inhibition Of Oxidation Of Β-Carotene–Linoleate Oil-In-Water Emulsion And Dna Strand Scission, Priyatharini Ambigaipalan, Won Young Oh, Fereidoon Shahidi

Tea epigallocatechin (EGC) was acylated with selected fatty acids, namely propionic acid [C3:0], caprylic acid [C8:0], lauric acid [C12:0], stearic acid [C18:0] and docosahexaenoic acid (DHA; C22:6 n-3). Antioxidant activity of EGC and its lipophilized derivatives were examined in various food (β-carotene–linoleate oil-in-water emulsion and bulk oil) and biological (supercoiled DNA and LDL) systems in vitro in order to evaluate the effect of increased lipophilicity on their antioxidant capacity. Lipophilized EGC derivatives were more effective in β-carotene–linoleate oil-in-water emulsion and bulk oil than their parent EGC molecule. Meanwhile, EGC and its derivatives showed more than 60 …

The Effects Of Adolescent Chronic Mild Stress: In Female Wistar-Kyoto Rats, Anna Hallowell

The Journal of Purdue Undergraduate Research

Despite years of research to understand under-lying mechanisms and develop more effective treatment approaches for mood disorders, numerous challenges exist. Many chronic stress models are used to study mood disorders, how-ever the majority have been established with adult males. This is problematic considering that affective disorders are more common in women, and generally develop during late adolescence. Studies have indicated fundamental behavioral, physiological, and neural differences between males and females in response to the same external stressors, furthering a need to develop sex-specific paradigms to accurately model the etiology of mood disorders in females. The Wistar-Kyoto (WKY) rat strain is …

In Search Of Homes: Climate Refugees Meet Walls, Afrikaan Osman

Alfie Scholars Conferences

The United Nations (UN) projects 200 million climate refugees (people displaced by climate change) by the year 2050, which is about 200 times more than the Syrian refugee crisis back in 2011 (UNHCR). All those people will lose their homes and wander around in search of new homes; some of them will become internally displaced people, and others will try to cross borders only to meet walls. The average person lives 17 years in a refugee camp before they relocate to a third country and get resettled. Refugee camps are some of the most populated and overcrowded places in the …

The Migration Of Medical Professionals From Dictatorships To The United States Of America: Why America Resists To Benefit From The Brain Drain, Viktoria Buina

Alfie Scholars Conferences

In the United States, the Migration Policy Institute reported 263,000 immigrants have degrees in health-related fields yet do not hold the positions in the healthcare system due to existing rigid licensing regulations. Despite the growing shortage of doctors which estimates to reach the levels between 54,100 and 139,000 physicians by 2033, these regulations still create an unnecessary timely and costly barrier for already experienced physicians. In the light of the Global COVID-19 pandemic, a number of possible solutions to ease the licensing process came out of the shadow. The main goal of this presentation is to explore the reasoning for …

Early Thoracentesis And Follow-Up In Coronary Artery Bypass Graft Patients, Jessica Kohler

Yale School of Medicine Physician Associate Program Theses

Coronary artery bypass graft surgery is a high-risk surgical intervention and commonly accounts for hospital readmissions within 30 days of discharge. Pleural effusions that require therapeutic thoracentesis are a reason for many of the readmissions. Studies have examined the adverse clinical effects that large volume pleural effusions have in these patients. However, effusion volume itself may have little influence on patient outcomes. Complications occur without close monitoring and drainage. In this study, we propose a randomized controlled trial to determine whether frequent follow-up and drainage of pleural effusions ≥320 ml can improve the need for rehospitalization and influence 6-minute walk …

Gaining A “Foothold” On The Diagnosis Of Leishmaniasis, Brent M. Troy, Rebecca Hart, Navjyot Vidwan, Bethany Hodge

Journal of Refugee & Global Health

Pediatric refugees and immigrants may present with unusual diagnoses due to their extensive migration and potential harsh conditions in travel. Trauma and family separation add to the difficulty of obtaining a history of exposures. We report a case of one of the more commonly neglected tropical diseases, Leishmaniasis. A 15-year-old male refugee patient presented to the hospital with ulcerative lesions to his legs. His migration history was extensive, starting in Central Africa with travel to South America, followed by migration through Central America to Texas. The patient developed ulcerative lesions on his legs, and he was brought to the children’s …

Evaluating Airsoft Electric Guns For Control Of Invasive Brown Treesnakes, Adam J. Knox, Björn Lardner, Amy Yackel Adams, Robert N. Reed

United States Geological Survey: Staff Publications

Firearms are often used in lethal control of invasive vertebrates, but safety and regulatory aspects limit the circumstances under which they can be used. During August 2016 at the Brown Treesnake Project laboratory on Guam, we evaluated hobby‐grade Airsoft Electric Guns (AEGs; a lower powered, less‐hazardous, and less‐regulated alternative to firearms) for capture and control of small animals, with specific emphasis on invasive brown treesnakes (Boiga irregularis). Tests of AEGs differing in power with ammunition (plastic pellets) masses ranging from 0.20 to 0.39 g, fired at gelatin blocks from distances of 4, 8, and 12 m, showed that …

Vampire Bats: Preparing For Range Expansion Into The U.S., Michael J. Bodenchuk, David L. Bergman

United States Department of Agriculture Wildlife Services: Staff Publications

The common vampire bat apparently is expanding its range northwards in Mexico and seems poised to enter the southern United States. Climate models predict suitable habitat in the U.S. in south Texas and parts of southern Arizona. While vampire bats’ northward range expansion is not unexpected, the fact that this species brings a strain of rabies that impacts livestock and people warrants a strategic response. Annual economic damages from bats are estimated between $7M and $9M, largely associated with deaths of livestock from rabies. To prepare for the emerging rabies issue, USDA Wildlife Services programs in Texas and Arizona have …
