Prevention Of Food Fraud In Egypt: Policy Implementation Challenges And The Way Forward, Hager Yehia Shalaby

Theses and Dissertations

Prevention and control of food fraud is now an emerging policy goal for different governments. Food fraud is intentionally adulterating food intended for personal gain and deceiving consumers. Adulterated food continues to be a significant threat to Egypt's food sector because of its negative impact on the food industry's reputation. Additionally, it jeopardizes the success of initiatives to increase investment, tourism, and exports in Egypt. Addressing fraud is, by definition, the most challenging food control system form because it directly addresses a personal stake benefiting from fraud behavior. In light of the importance of food fraud prevention as an emerging …

Development Of An Electromagnetic System For Wireless Magnetic Manipulation Of Soft Capsule Endoscope For Drug Delivery Applications, Nada Ashraf Hussein Mahmoud

Theses and Dissertations

Wireless capsule endoscopy (WCE) is a remarkable diagnostic device that examines the gastrointestinal (GI) tract. The WCE is a small capsule integrated with a camera that is used to visualize the inner mucosa of the GI tract. WCE has been proven to be the most effective method to diagnose GI diseases and GI cancers. The procedure reduces the discomfort and risk compared to conventional endoscopy methods. However, current WCEs lack the ability to take a biopsy or deliver a drug to a specific location. Those therapeutic functions can be introduced by wirelessly controlled WCEs. This thesis introduces an electromagnetic system …

Cardiac Active Tension Modeling Via Genetic Algorithm-Optimized Fractional Order Systems, Afnan Khaled Elhamshari

Theses and Dissertations

Developing a computational model to model cardiac activity has been increasingly important in recent decades. Accurate cell-level active tension modeling for cardiomyocytes is critical to understanding cardiac functionality on a patient-specific basis and developing an effective in-silico cardiac model. However, cell-level models in the literature fail to account for viscoelasticity and inter-patient variations in active tension. This research proposes a genetic algorithm-optimized, fractional order system to model cell-level active tension by extending Land’s state-of-the-art model of cardiac contraction. The model features the (left) Caputo derivative of six state variables that identify the mechanistic origins of viscoelasticity in a myocardial cell …

A 3d Imaging-Based Critique Of Wire Arc Additive Manufacturing (Waam) Simulations, Omar Oraby

Theses and Dissertations

Residual stresses play a critical role in the mechanical behavior and structural integrity of engineered components. Understanding and quantifying these stresses are essential for ensuring the reliable performance and durability of materials and structures. Traditionally destructive methods are used that involve sample sectioning and material removal. However, non-destructive methods have gained popularity due to their advantages in preserving the specimen's integrity for further testing and material waste reduction. Among these techniques, Digital Image Correlation (DIC) stands out as a powerful non-contact and full-field measurement approach. DIC captures displacements and strain distributions by analyzing the deformation of speckle patterns on the …

The Consequences Of Civil-Military Relations On Civil Wars In The Middle East, Alaa Bahnasy

Theses and Dissertations

To unravel the complex dynamics surrounding the outbreak of civil wars in the aftermath of the Arab Spring uprisings, one of the first questions that come to mind is the reason why some Arab countries have witnessed civil wars whilst others have not. The civil-military relations play a significant role in the matter. While much of the existing literature on the causes of civil wars, there is a scarcity of papers that take into consideration the role of civil-military relations. This research focuses primarily on two variables independent variables, namely the civil-military relations and the diversified ethnicities alongside the dependent …

Division of Nephrology Faculty Papers

Previous investigators have used various anti-HLA-F monoclonal antibodies (mAbs) to demonstrate that the tissue distribution of HLA-F is highly restricted. Notably, these mAbs differed in their immunodiagnostic capabilities. Specifically, mAbs Fpep1.1 and FG1 detected HLA-F intracellularly in B cells but not on the cell surface, whereas mAb 3D11 detected HLA-F on the cell surface. The presence of HLA-F on T cells was recognized by mAb FG1 but not by mAb Fpep1.1. mAb 3D11 detected HLA-F on the cell surface of activated B cells and on peripheral blood lymphocytes, but not on the normal cells. Importantly, mAb 3D11 revealed that HLA-F …

Pharmacology and Clinical Pharmacy Research

Sepsis, a life-threatening organ dysfunction resulting from a dysregulated host response to infection, induces changes in blood cells and metabolic alterations. Fatty acid binding protein 4 (FABP4), a lipid chaperone predominantly expressed in adipose tissue, is modulated in sepsis and may contribute to metabolic and immunologic changes. Moringa oleifera (M. oleifera) leaf extract (MOLE) is known to modulate immune system activity, but its potential for treating acute inflammatory conditions like sepsis remains unclear. This study investigates the ability of MOLE to modulate metabolite and hematological profiles in lipopolysaccharide (LPS)-induced sepsis in mice. Thirty-five male Swiss Webster mice (Mus musculus) were …

The Mef2c Gene Dose-Dependently Controls Hippocampal Neurogenesis And The Expression Of Autism-Like Behaviors, Sreetama Basu, Eun Jeoung Ro, Zhi Liu, Hyunjung Kim, Aubrey Bennett, Seungwoo Kang, Hoonkyo Suh

The Brown Foundation: Institute of Molecular Medicine

Mutations in the activity-dependent transcription factor MEF2C have been associated with several neuropsychiatric disorders. Among these, autism spectrum disorder (ASD)-related behavioral deficits are manifested. Multiple animal models that harbor mutations in Mef2c have provided compelling evidence that Mef2c is indeed an ASD gene. However, studies in mice with germline or global brain knock-out of Mef2c are limited in their ability to identify the precise neural substrates and cell types that are required for the expression of Mef2c-mediated ASD behaviors. Given the role of hippocampal neurogenesis in cognitive and social behaviors, in this study we aimed to investigate the role …

Malignant forms of breast cancer refractory to existing therapies remain a major unmet health issue, primarily due to metastatic spread. A better understanding of the mechanisms at play will provide better insights for alternative treatments to prevent breast cancer cell dispersion. Here, we identify the lysine methyltransferase SMYD2 as a clinically actionable master regulator of breast cancer metastasis. While SMYD2 is overexpressed in aggressive breast cancers, we notice that it is not required for primary tumor growth. However, mammary-epithelium specific SMYD2 ablation increases mouse overall survival by blocking the primary tumor cell ability to metastasize. Mechanistically, we identify BCAR3 as …

Poor oral health is associated with cardiovascular disease and dementia. Potential pathways include sepsis from oral bacteria, systemic inflammation, and nutritional deficiencies. However, in post-industrialized populations, links between oral health and chronic disease may be confounded because the lower socioeconomic exposome (poor diet, pollution, low physical activity) often entails insufficient dental care. We assessed tooth loss, caries, and damaged teeth, in relation to cardiovascular and brain aging among the Tsimane, a subsistence population living a relatively traditional forager-horticulturalist lifestyle with poor dental health, but minimal cardiovascular disease and dementia. Dental health was assessed by a physician in 739 participants aged …

Candussi, Anna Tresserra-Rimbau, Amy Jennings, Nicola P. Bondonno, Claire Hill, Solomon A. Sowah, Aedín Cassidy, Tilman Kühn

Research outputs 2022 to 2026

Background: Plant-based diets are becoming increasingly popular due to favourable environmental footprints and have been associated with lower risk of type 2 diabetes mellitus (T2DM). Here, we investigated the potential mechanisms to explain the lower T2DM risk observed among individuals following plant-based diets. Methods: Prospective data from the UK Biobank, a cohort study of participants aged 40 to 69 years at baseline, was evaluated. Associations between healthful and unhealthful plant-based indices (hPDI and uPDI) and T2DM risk were analysed by multivariable Cox regression models, followed by causal mediation analyses to investigate which cardiometabolic risk factors explained the observed associations. Results: …

Remediation For Pfas Contamination: The Role Of Cercla Enforcement In Environmental Justice, Amanda F. Watson

Georgia Law Review

PFAS are a family of manufactured chemicals that are highly persistent in the environment. Most people in the U.S. have been exposed to PFAS, but different groups of people may have higher exposure due to their environments. In recent years, peer-reviewed scientific studies have shown that PFAS are linked to numerous adverse human health effects. As a result, the U.S. Environmental Protection Agency (EPA) has taken a variety of actions to address PFAS, including proposing to designate PFOS and PFOA, two chemicals in the PFAS family, as hazardous substances under CERCLA, or Superfund. CERCLA is the primary legal mechanism in …

Testing The Limits Of Virtual Compliance: Website Accessibility, "Tester" Plaintiffs, And Article Iii Standing Under The Ada, Ashlyn Dewberry

Georgia Law Review

Federal courts have split in determining whether “tester” plaintiffs bringing suit under the ADA assert the requisite injury in fact necessary for Article III standing. These “website accessibility testers” allege that defendants’ websites do not make certain information available to disabled persons in violation of Title III of the ADA and one of its implementing regulations. This split presents an excellent opportunity to clarify which informational and stigmatic harms qualify as injuries in fact for Article III standing purposes. This Note argues that ADA website accessibility testers cannot obtain standing under current law. Neither the text of the ADA nor …

Irreversible Electroporation Of The Hepatobiliary System: Current Utilization And Future Avenues, Govindarajan Narayanan, Yilun Koethe, Nicole Gentile

All Publications

Liver cancer remains a leading cause of cancer-related deaths worldwide despite numerous advances in treatment. While surgical resection remains the gold standard for curative treatment, it is only possible for a minority of patients. Thermal ablation is an effective option for the treatment of smaller tumors; however, its use is limited to tumors that are not located in proximity to sensitive structures due to the heat sink effect and the potential of thermal damage. Irreversible electroporation (IRE) is a non-thermal ablative modality that can deliver targeted treatment and the effective destruction of tumors that are in close proximity to or …
