Simultaneous FD and CW recordings were implemented to speed up acquisition to 3 minutes for all 9 wavelengths, spanning a range from 661nm to 1064nm. An adjustable interface was designed to fit various breast sizes and shapes. Spatial images of oxy- and deoxy-hemoglobin, water, lipid, and scattering components were reconstructed using a 2D FEM approach. The system was tested on a group of 10 normal subjects, who were examined bilaterally …

Biodegradable Magnesium Alloys For Orthopaedic Applications: A Review On Corrosion, Biocompatibility And Surface Modifications., Sankalp Agarwal, James Curtin, Brendan Duffy, Swarna Jaiswal

Articles

Magnesium (Mg) and its alloys have been extensively explored as potential biodegradable implant materials for orthopaedic applications (e.g. Fracture fixation). However, the rapid corrosion of Mg based alloys in physiological conditions has delayed their introduction for therapeutic applications to date. The present review focuses on corrosion, biocompatibility and surface modifications of biodegradable Mg alloys for orthopaedic applications. Initially, the corrosion behaviour of Mg alloys and the effect of alloying elements on corrosion and biocompatibility is discussed. Furthermore, the influence of polymeric deposit coatings, namely sol-gel, synthetic aliphatic polyesters and natural polymers on corrosion and biological performance of Mg and its …

Strategic Planning For Setting Up Base Stations In Emergency Medical Systems, Supriyo Ghosh, Pradeep Varakantham

Research Collection School Of Computing and Information Systems

Emergency Medical Systems (EMSs) are an important component of public health-care services. Improving infrastructure for EMS and specifically the construction of base stations at the ”right” locations to reduce response times is the main focus of this paper. This is a computationally challenging task because of the: (a) exponentially large action space arising from having to consider combinations of potential base locations, which themselves can be significant; and (b) direct impact on the performance of the ambulance allocation problem, where we decide allocation of ambulances to bases. We present an incremental greedy approach to discover the placement of bases that …

Graphene Quantum Dots-Based Drug Delivery For Ovarian Cancer Therapy, Yiru Qin

USF Tampa Graduate Theses and Dissertations

Ovarian cancer, one of the most dreadful malignancies of the female reproductive system, poses a lethal threat to women worldwide. In this dissertation, the objective was to introduce a novel type of graphene quantum dots (GQDs) based nano-sized drug delivery systems (DDS) for ovarian cancer treatment. As a starting point, the facile synthesis method of the GQDs was established. Subsequently, the targeting ligand,folic acid (FA), was conjugated to GQDs. Next, a FDA approved chemotherapeutic drug, Doxorubicin (DOX), was loaded to form the GQDs-FA-DOX nano-conjugation as the DDS. Moreover, the uptake profile and anti-cancer effect of the GQDs-FA-DOX were validated in …

Less than half of patients suffering from major depressive disorder, a leading cause of disability worldwide, achieve remission with current antidepressants, making it imperative to develop more effective treatment. A new therapeutic direction is emerging from the increased understanding of natural resilience as an active stress-coping process. It is known that potassium (Kþ) channels in the ventral tegmental area (VTA) are an active mediator of resilience. However, no druggable targets have been identified to potentiate active resilience mechanisms. In the chronic social defeat stress model of depression, we report that KCNQ-type Kþ channel openers, including FDA-approved drug retigabine (ezogabine), show …

From Jim Crow To Racial Tolerance: The African-American Experience During Interwar Period Paris, Nicole Schindel

Binghamton University Undergraduate Journal

During World War I, African-American soldiers came to France and discovered the relative diminishment of racial prejudices in the country. Since much of the United States still held racist Jim Crow era laws and prejudices, African-Americans had been barred from the same opportunities as their white counterparts. Because of this, many African- Americans moved to Paris during the interwar period to seek opportunities that were not available to them in the United States. This paper will explore how the less rigid and more nuanced racial ideologies found in Paris, enabled African-Americans to create strong relationships with Parisians and find the …

Womanhood Initiation, Anna Szilagyi

Binghamton University Undergraduate Journal

Womanhood Initiation is a poem I wrote during Maria Gillan's Advanced Poetry Workshop. Professor Gillan is a Professor of English at Binghamton University, and her workshop is unique in that it takes place during three long weekend sessions throughout the semester. This specific poem was inspired by one of Professor Gillan’s writing prompts: “I do not feel like a man/woman yet.” I tend to explore gender in my poetry, specifically girlhood and womanhood. Young women and girls, often put down in United States culture for their vanity and selfishness, are complex, intelligent people and have more to say that should …

Examining Primarily White Institutions Of Higher Education: Black Student Experience In The 1960s, Oluwashola Gbemi

Binghamton University Undergraduate Journal

A major outcome of the Civil Rights Act of 1964 was the desegregation of higher-learning institutions. Despite this, there was little change regarding the character and cultural norms of predominantly white institutions (PWIs) of higher learning. In this review of literature discussing the experiences of Black students attending PWIs during the 1960s, I argue that cultural norms such as racial discrimination yielded a detrimental impact on the success and wellbeing of African-American students. While I discuss what quality wellbeing for African-American students entails, I highlight the significance of black student unions to the wellbeing of black students. In order to …

Challenging Linguistic Superiority Through Social Attitudes: Language Complexities Of The Ukrainian Diaspora In The United States, Anna Pinchuk

Binghamton University Undergraduate Journal

The English language in the United States has a strong legacy of linguistic imperialism that started with bans on the use of languages spoken by indigenous people in the early 1800s. The assumptions behind those policies were that the English language was civilized and progressive, while all other languages were barbaric and improper. In this paper, I examine how the historic language policies in the United States continue to create barriers in non-native speakers’ success and achievement in social and political spheres. I proceed by discussing the English-only policies and native language bans that started the legacy of English superiority …

Do Natural Disasters Induce More Crime?, Michael Lentini, Plamen Nikolov, Matthew Schwartz

Binghamton University Undergraduate Journal

The Indian Ocean Tsunami of 2004 resulted in grave consequences for South East Asia. Indonesia, in particular, had the highest death toll, losing over 150,000 people. Indonesia’s coastal region Aceh was the hardest hit by this disaster. Exploiting exogenous spatial variation at the district level, we use difference-in-difference analysis to estimate the causal effect of the 2004 disaster on subsequent crime rates. We find that after the tsunami, total annual crime rate went down, on average, by 244 crimes per annum.

Mental Health Initiatives For Asian American Women, Karen Lin

Binghamton University Undergraduate Journal

Despite being one of the fastest growing minorities of the United States, Asian Americans are most at risk for developing mental disorders and least likely to seek professional help. With a significant portion of the United States represented by Asian ethnicities, addressing the mental health needs of this population is not only important but necessary to advance the overall health of all Americans. The purpose of this paper is to describe the influences of cultural norms and standards that increase risk factors for poor mental health outcomes and negative help seeking attitudes in first generation Asian American college-aged females. These …

Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez

Biology: Student Scholarship & Creative Works

ABSTRACT: The HIV-1 pandemic continues to thrive due to ineffective HIV-1 vaccines. Historically, the world’s most infectious diseases, such as polio and smallpox, have been eradicated or have come close to eradication due to the advent of effective vaccines. Highly active antiretroviral therapy is able to delay the onset of AIDS but can neither rid the body of HIV-1 proviral DNA nor prevent further transmission. A prophylactic vaccine that prevents the various mechanisms HIV-1 has to evade and attack our immune system is needed to end the HIV-1 pandemic. Recent advances in engineered nuclease systems, like the CRISPR/Cas9 system, have …

Multiphoton Imaging Of Labeled Breast Cancer Cells To Quantify Intra And Extracellular Receptors, Sydney C. Wiggins

Biomedical Engineering Undergraduate Honors Theses

Every year 200,000 women in the United States are diagnosed with breast cancer. Of the cases diagnosed, 10% -15% are classified as triple negative breast cancer (TNBC) due to the absence of estrogen, progesterone, and HER-2/Neu receptors. This breast cancer sub-type is markedly more aggressive and twice as likely to develop in premenopausal women. TNBC is resistant to endocrine therapies and current targeted agents, making clinical need for the development of validated therapeutics for TNBC a pressing matter. To initiate drug development, the internalization of directly immunolabeled epidermal growth factor receptors (EGFR) in SK-BR-3 human breast adenocarcinoma cells was quantitated …

Development Of A Simple Handheld Biosensor For Waterborne Pathogens, Bryce C. Jones

Chemical Engineering Undergraduate Honors Theses

Current methods of detecting waterborne pathogens involve testing strips which take 24-48 hours to yield results, or require expensive equipment in order to function. In minimalist environments, these two technologies are not always applicable to test water quality. With the emergence of a new method of PCR, named LAMP PCR, it is possible to quickly and accurately detect pathogen DNA in a water sample. In order to scale this technique into a simple device, the aspects of the reaction must be accommodated, and a visual detection method chosen. A handheld device which keeps the isothermal LAMP PCR stable for the …

In the field of orthopedic devices implant loosening is a major issue resulting in the majority of device failures. These failures result in the need for costly secondary procedures. To reduce device loosening an improved method of tissue anchoring is required. A previously studied titanate nanofiber bioscaffold has been shown to be safely implantable and to contribute to the differentiation of mesenchymal stem cells to osteocytes. Through the customization of both physical and chemical characteristics this titanate nanofiber bioscaffold was fabricated as a potential means to enhance tissue anchoring for use with orthopedic devices. This customization was enabled by acoustic …

Lesion Identification And The Effect Of Lesion On Motor Mapping After Stroke, Ruixi Zhou

McKelvey School of Engineering Graduate Student Theses & Dissertations

Stroke is the most common cause of long-term severe disability and the motor system that is most commonly affected in stroke. One of the mechanisms that underlies recovery of motor deficits is reorganization or remapping of functional representations around the motor cortex. This mechanism has been shown in monkeys, but results in human subjects have been variable. In this thesis, I used a database that includes longitudinal behavioral and multimodal imaging data in both stroke patients and healthy controls for two research projects. Firstly, I improved an automatic lesion segmentation method to aid in the identification of the location and …

Crizotinib And Ceritinib Induce Apoptosis And Necrosis In Primary Rat Hepatocytes With Distinct Capacity, Alec T. Salminen

Biomedical Engineering Undergraduate Honors Theses

Drug development makes up a major portion of biomedical engineering research interests. The FDA oversees the introduction, experimentation, and implementation of all drugs before market approval is granted. Even after market approval is granted, the FDA continues to monitor the safety of all drugs. Crizotinib and ceritinib are two anaplastic lymphoma kinase (ALK) inhibitors recently approved by the FDA. Both drugs are indicated for treatment of non-small cell lung cancers (NSCLC) with abnormal ALK gene, and they are approved with a companion diagnostic test that determines ALK abnormality. Clinical trial data suggest that crizotinib and ceritinib can cause liver injury, …

Micellular Electrokinetic Chromatography For Studying Amyloid Beta Oligomer Membrane Affinity, Andrew Bryson

Biomedical Engineering Undergraduate Honors Theses

Amyloid Beta (Aβ) was the major focus of this study. It is a peptide that is present in the brain with a high tendency to self-aggregate. When this protein aggregates, it forms oligomers and protofibrils which in turn are deposited as senile plaques in the brain. The reason for the concern with these plaques is their association with the neurological disorder Alzheimer’s disease. It has been found that the most dangerous oligomers are formed in a portion of the plasma membrane known as lipid rafts. The purpose of this study was to understand how micelles affect the aggregation properties of …
