Cellular Mechanism Of Pentagalloyl Glucose-Mediated Prevention And Reversal Of Abdominal Aortic Aneurysms, Greg Halsey

All Dissertations

Abdominal aortic aneurysm (AAA) has been the 15th leading cause of death in persons older than 55 for the past ten years in several Western countries, with rupture resulting in an almost 100% mortality rate. AAA is a focal dilation of the aorta characterized by progressive loss of elastin and vascular smooth muscle cells (SMCs), as well as persistent inflammatory response [1]. The only treatment for AAA is surgery; however, the mortality post-procedure is still 1-4%, with a 15-30% chance of morbidity [2].

Pentagalloyl glucose (PGG) treatment is effective in the reversal of AAA. While its stabilizing interactions with extracellular …

A Review Of Threat Vectors To Dna Sequencing Pipelines, Tyler Rector

Cybersecurity Undergraduate Research Showcase

Bioinformatics is a steadily growing field that focuses on the intersection of biology with computer science. Tools and techniques developed within this field are quickly becoming fixtures in genomics, forensics, epidemiology, and bioengineering. The development and analysis of DNA sequencing and synthesis have enabled this significant rise in demand for bioinformatic tools. Notwithstanding, these bioinformatic tools have developed in a research context free of significant cybersecurity threats. With the significant growth of the field and the commercialization of genetic information, this is no longer the case. This paper examines the bioinformatic landscape through reviewing the biological and cybersecurity threats within …

Flavonol Glucosylation: A Structural Investigation Of The Flavonol Specific 3-O Glucosyltransferase Cp3gt, Aaron S. Birchfield

Electronic Theses and Dissertations

Flavonoid glycosyltransferases (GTs), enzymes integral to plant ecological responses and human pharmacology, necessitate rigorous structural elucidation to decipher their mechanistic function and substrate specificity, particularly given their role in the biotransformation of diverse pharmacological agents and natural products. This investigation delved into a comprehensive exploration of the flavonol 3-O GT from Citrus paradisi (Cp3GT), scrutinizing the impact of a c-terminal c-myc/6x histidine tag on its enzymatic activity and substrate specificity, and successfully achieving its purification to apparent homogeneity. This established a strong foundation for potential future crystallographic and other structure/function analyses. Through the strategic implementation of site-directed mutagenesis, a thrombin …

Controlled Radiation Capsule For Precision And Rapid Cancer Treatment, Hoseon Lee, Zsolt Kollar, Bailey R. White, Junia Nguyen, David Roque, Sowjanya Palagani

Symposium of Student Scholars

This research aims to transform cancer treatment through the optimization of brachytherapy, with a focus on reducing treatment duration, setup complexities, and financial burdens, all while emphasizing patient safety. Patients living at a distance from radiation clinics, particularly those undergoing extended Low Dose Radiation brachytherapy, often struggle with the formidable financial challenges associated with securing nearby accommodations. In response to these issues, the research introduces a radiation capsule designed to condense the conventional six-month treatment period to approximately just one week, thereby significantly reducing the duration of required accommodations. This capsule is especially relevant considering the construction cost of $40 …

Evaluation Of Crocus Sativus L. Quality Using Ftir Spectroscopy, Lina M. Alnaddaf, Mohamad Nabil Ksaier, Salim F. Bamsaoud

Hadhramout University Journal of Natural & Applied Sciences

Crocus sativus L. is one the important spices that gives food a distinctive color and taste as well as its medicinal value. Its quality can be estimated using different analysis methods. In This study we used FTIR spectroscopy to Evaluate Crocus sativus L. quality at MEDICO Lab 2023. FTIR Spectroscopy is a fast and reliable analytical method for quality saffron evaluation. The results of FTIR spectra indicated functional groups related to O-H, C=C, C=O, C-O, C(O)–O, C-H, C-H (cis-) and C-H (trans-). Also, our samples lacked the distinctive bands of the active substances of crocetin. Furthermore, …

Effects Of Thinning On The Incidence Of Damage And Severity Of Decay In Bagras (Eucalyptus Deglupta Blume) Plantations, Emelio Anino

ASEAN Journal on Science and Technology for Development

Thinning of intermediate and suppressed trees has been implemented on 3- to 4-year-old bagras (E. deglupta) plantations in Surigao de! Sur, Philippines. The objective is to remove unwanted competition and to gain some form of revenue by selling the felled trees as banana props. However, the falling trees caused damage to other plantation trees. Bagras is susceptible to heart rot. A study was, therefore, conducted to determine the extent of decay in bagras due to thinning. Data showed that injured bagras developed extensive decay in the sapwood and heartwood. Six percent of the injured trees died. Retained-trees, which were already …

Seasonal Orientation Of Solar Collectors For The Philippines, Saiful Bari

ASEAN Journal on Science and Technology for Development

In this paper, a method to determine the slope angle for seasonal applications of flat plate collectors is described for the Philippines territory. For seasonal applications, where the collectors are used only for a fraction of the year, the slope angles need to be different from those for year-round operations. For year-round operations, most flat collectors are usually fixed, and mounted at an angle equal to the latitude tilt angle. The method described here utilized both direct and diffuse components of solar radiation, and air mass using average atmosphere. For seasonal applications of solar energy such as crop drying, the …

Thermal Diffusivity Measurements Using Open Photoacoustic Cell Technique, W. Mahmood Mat Yunus, C. Y. J. Fanny, I. V. Grozesu, S. A. Halim, M. M. Moksin

ASEAN Journal on Science and Technology for Development

The application of open photoacoustic cell (OPC) technique is demonstrated for measuring thermal diffusivity of solid samples. It is based upon the measurement of the photoacoustic signal in the modulation frequency region where the thermal diffusion length equals to the sample thickness. The measurements were carried out at room temperature for gold alloys (Au0 75Ag0.and Au. Ag. ); epoxidised natural rubbers 25 0 50 0 50 [ENR 25 (75%C ) and ENR 50 (75%C)]; and supercond ucti ng ceramics (Bi2Pb0 .6 Sr2Ca1.94Ba 0. Cu 0 , and Bi Pb . Sr Ca1. Zn. Cu 0 ) . The thermal 06 …

An Experiment With Spiral Wound Reverse Osmosis Membranes For The Desalination Of Seawater, M.N.A. Hawlader, J.C. Ho, K. T. Chua

ASEAN Journal on Science and Technology for Development

In the research, the performance characteristics of Reverse Osmosis (RO) Spiral Wound (SW) membrane are evaluated. The effects of feed water concentration, temperature, pressure and flow rate on the performance of this membrane are investigated. The product recovery () of SW membrane is found to increase with feed water temperature and pressure, but decrease with increasing feed water concentration and flow rate. Salt passage (SP) increases with feed water temperature and concentration, but decreases with increasing feed pressure and flow rate. Under the tested feed water conditions, of SW varies from 6% - 18% and permeate salinity is approximately …
