Description
More than 260 million people suffer from an anxiety disorder worldwide, with 40 million in the U.S. alone—18% of the American population. And that label includes everything from Social Anxiety and Posttraumatic Stress Disorder to phobias and Obsessive Compulsive Disorder. Thus, people with anxiety may not have a singular cause for their worry, but a myriad number of them that influence every aspect of their lives. And, that doesn’t include people who’ve never been formally diagnosed and don’t receive proper medication or therapy.
Unfortunately, medication has many possible side effects, and both medication and therapy are often expensive. However, there are alternatives for someone dealing with anxiety. This book proposal offers a range of solutions for anxiety management, from do it yourself techniques like guided imagery and yoga, to biofeedback devices like HeartMath, to research trials on Eye Movement Desensitization and Reprocessing, as well as Repetitive Transcranial Magnetic Stimulation. The idea was not to outline every potential solution for anxiety, but to educate people on available opportunities and empower them to take control.
Though anxiety can be managed and reduced, there is no cure. That’s because anxiety is a normal part of life, and in most cases a helpful evolutionary tool to keep people on track. But, when this anxiety becomes a burden on someone’s life, there is a plethora of alternative solutions available. Understanding anxiety and learning to manage it is not an impossible task. This thesis provides an introduction to the idea and then allows the reader to move forward on their own path as they choose.

Description
Influenza is a deadly disease for which effective vaccines are sorely lacking. This is largely due to the phenomena of antigenic shift and drift in the influenza virus's surface proteins, hemagglutinin (HA) and neuraminidase (NA). The ectodomain of the matrix 2 protein (M2e) of influenza A, however, has demonstrated high levels of conservation. On its own it is poorly immunogenic and offers little protection against influenza infections, but by combining it with a potent adjuvant, this limitation may be overcome. Recombinant immune complexes, or antigens fused to antibodies that have been engineered to form incredibly immunogenic complexes with one another, were previously shown to be useful, immunogenic platforms for the presentation of various antigens and could provide the boost in immunogenicity that M2e needs to become a powerful universal influenza A vaccine. In this thesis, genetic constructs containing geminiviral replication proteins and coding for a consensus sequence of dimeric M2e fused to antibodies featuring complimentary epitopes and epitope tags were generated and used to transform Agrobacterium tumefaciens. The transformed bacteria was then used to cause Nicotiana benthamiana to transiently express M2e-RICs at very high levels, with enough RICs being gathered to evaluate their potency in future mouse trials. Future directions and areas for further research are discussed.

Description
Virus-Like Particles (VLPs) are self-assembling structures that lack the viral genetic material. Therefore they are safer and more immunogenic than other forms of vaccines. The Hepatitis B core (HBc) VLPs are a novel mechanism through which delivery of DNA-based human vaccines are plausible. Production of VLPs require recombinant, rapidly replicating, plant-based systems such as the geminiviral replicon system. This project entails the cloning process of HBc-DIII fusion protein, a VLP that should form Domain III of the Envelope protein on West Nile Virus, into deconstructed geminiviral vector. The cloning process includes the HBc-DIII fusion protein DNA isolation, restriction enzyme digestion with NcoI and SacI, PCR changing the NcoI site on the HBc-DIII insert to XbaI, sequencing, ligation into geminiviral vector and transformation into an agrobacterium strain. The major impediment to the cloning process was the presence of multiple bands instead of the expected two bands while doing restriction enzyme digests. The troubleshooting process enabled speculating that due to the excess of restriction enzymes in the digestion volume, some of the DNA was not digested completely. Hence, multiple bands were observed. However, sequencing analysis and further cloning process ensured the presence of HBc-DIII insert band (approximately 800bp) in the Gemini vector. Lastly, the construct HBc-DIII in Gemini vector was ensured to be in agrobacterium for further experiments such as agro-infiltration.

Description
Climate change presents a significant threat to human health, both mental and physical; as a result, it has become one of the most commonly discussed phenomena of the 21st century. As many people are aware, a wide range of social and physical factors affects mental health. However, many people fail to realize that these increases global temperatures also have a significant impact on mental health as a result of increased vulnerability that is often manifested through one's emotions. By analyzing perceptions of people across the globe, in the United Kingdom, New Zealand, and Fiji, we were able to pinpoint these emotions and trace them individual's feelings of worry, distress, and hope that resulted from their perceived impacts on climate change. Overall, we found that people tend to have overall more negative emotional reaction when it comes to the perceived effects of climate change. Of the respondents, more men than women expressed concern regarding the various negative implications. Finally, those in the United Kingdom exhibited a stronger emotional response, followed by those in New Zealand and Fiji, respectively.

Description
This research explores the unique and complicated experiences of women living with Von Willebrand Disease (VWD). VWD occurs with quantitative or qualitative deficiencies in Von Willebrand Factor—a key protein involved in blood clotting. While VWD affects men and women, women often suffer harsher complications because of menstruation, childbirth, and other women’s health issues. Using online VWD support groups, this research recognizes and attempts to understand the common experiences of women with VWD. Availability of Care, Motherhood, Community and Sisterhood, Girlhood, Sexual Health and Reproductive Health, and Stigma were the six common themes found within these online support groups. Women in these groups corroborate the current understandings of women-specific experiences with VWD: particularly, heavy menstruation, postpartum hemorrhaging, diagnostic difficulties, treatment complications, and implications of an overall lower quality of life. However, these women also report VWD-induced complications with sexual health, mental health, care when trying to conceive, misinterpretations of bruising, constraints on healthcare availability, and the stigma associated with heavy menstruation. These findings address gaps in the literature and identify new areas for further research. Ideally, these conclusions will provide educational materials for healthcare professionals, government legislatures, and families to better support women and girls with VWD.

Description
The human hairless gene (HR) encodes a 130 kDa transcription factor that is primarily expressed in the brain and skin. In the promoter and 5'-untranslated regions (5'-UTR) of HR, there are three putative consensus p53 responsive elements (p53RE). p53 is a tumor suppressor protein that regulates cell proliferation, apoptosis, and other cell functions. The p53 protein, a known tumor suppressor, acts as a transcription factor and binds to DNA p53REs to activate or repress transcription of the target gene. In general, the p53 binding sequence is 5'-RRRCWWGYYY-3' where W is A or T, and R and Y are purines or pyrimidines, respectively. However, even if the p53 binding sequence does not match the consensus sequence, p53 protein might still be able to bind to the response element. The intent of this investigation was to identify and characterize the p53REs in the promoter and 5'-UTR of HR. If the three p53REs (p53RE1, p53RE2, and p53RE3) are functional, then p53 can bind there and might regulate HR gene expression. The first aim for this thesis was to clone the putative p53REs into a luciferase reporter and to characterize the transcription of these p53REs in glioblastoma (U87 MG) and human embryonic kidney (HEK293) cell lines. Through the transactivation assay, it was discovered that p53REs 2 and 3 were functional in HEK293, but none of the response elements were functional in U87 MG. Since p53 displayed a different regulatory capacity of HR expression in HEK293 and U87 MG cells, the second aim was to verify whether the p53REs are mutated in GBM U87 MG cells by genomic DNA sequencing.

Description
My thesis project, "An Ethical Evaluation of the Practice of Psychiatric Patient Boarding in the Emergency Department" sets out to address a relatively nameless problem in the healthcare system in the United States. This problem is the boarding of psychiatric patients in emergency departments nationwide. What is psychiatric patient boarding? This term refers to the increasingly common practice of care provided to psychiatric patients upon arrival at an emergency department. When inpatient psychiatric beds or services are not available, "boarding" is performed by simply storing mentally ill patients in hallways or other emergency room areas while they wait for the availability of psychiatric treatment, which may take hours, or in more extreme cases has been cited to last for days at a time (Alakeson et. al, 2010). While any individual can expect to wait a prolonged period of time for medical care in the increasingly overcrowded emergency departments, the psychiatric patient experience is astonishingly unique. A psychiatric patient presenting, or arriving, at the ED in crisis can often times find him or herself not only waiting hours to be admitted and assessed as a medical patient would, but with a limited and ever attenuating supply of psychiatric treatment rooms and services, these patients will often times be harbored in an ED room designed for short-term medical treatment without care until psychiatric services become available. Patients can be left waiting for days for an in-patient vacancy; all the while not receiving true psychiatric treatment and in some cases being held against their will in a chaotic environment far from conducive for treatment of a mental health ailment. In this analysis, I will discuss and review aspects of psychiatric patient boarding from various literature, such as why boarding occurs from a hospital and historical standpoint, negative implications of boarding for psychiatric and medical patients, and the burden placed on the hospital when practicing psychiatric boarding. To learn further on the topic, I will share the results from 14 semi-structured, qualitative interviews performed with ED healthcare professionals, being physicians, charge nurses, nursing staff, and certified nursing assistants or patient safety advocates. This portion of my investigation is designed to offer a perspective that the literature cannot, being a first hand outlook on psychiatric boarding from those working on the front line, focusing on topics of all aspects, such as causation, consequences for all involved parties, and proposed solutions.

Description
The major goal of this large project is to develop a Recognition Tunneling Nanopore (RTP) device that will be used for determining the structure of glycosaminoglycans (GAGs). The RTP device is composed of a recognition tunneling junction that is embedded in a nanopore. In order to translocate the GAG molecule through the nanopore, researchers have designed a scheme in which the GAG molecule of interest will be attached to the 5’ end of a DNA primer (figure 1) and the DNA primer will be extended by a biotinylated Φ29 DNA polymerase that is anchored in the nanoslit using streptavidin. This research project specifically is part of a larger project with the main goal of comparing the activity of the wild-type Φ29 DNA polymerase which I have expressed and purified with the mutated Φ29 DNA polymerase devoid of 3’ - 5’ exonuclease activity which was made by Dr. Deng.

Description
In medical field today, current diagnostic tools for neurodegenerative diseases fail to diagnose patients prior to the occurrence of damaging neuronal loss. Oftentimes, this means that by the time a patient has been diagnosed with a disease such as Alzheimer's disease (AD) or Parkinson's disease (PD), they have already suffered severe, irreversible neurodegeneration. One of the significant weaknesses in the diagnosis and treatment of patients with AD and PD is the lack of viable biomarkers. Biomarkers are vital tools that can be utilized to identify patients who are in presymptomatic stages of a disease, track and quantify disease progression, and also determine whether or not a patient is responding to a particular treatment. RNAs are involved in all cellular processes, and due to their very specific spatial, temporal, and even cellular-level expression, abnormal expression signatures serve as key indicators of many diseases. Recently, cells have been shown to secrete nanometer-sized microvesicles, called exosomes, which moderate the horizontal transfer of mRNAs and miRNAs between cells. We hypothesize that exosomes obtained from human biofluids, such as cerebral spinal fluid (CSF) and blood plasma, can be used to determine extracellular RNA (exRNA) expression signatures associated with neurodegenerative disease. This experiment used pooled samples of CSF and plasma in order to investigate which of 3 sample enrichment methods would be most conducive to studying exRNA contained within exosomes. The results from this preliminary investigation will be used in later investigations that will seek to determine exRNA biomarkers of neurodegenerative disease.

Description
Extrachromosomal circular DNA (eccDNA) has been identified in a broad range of eukaryotes and have been shown to carry genes and regulatory sequences. Additionally, they can amplify within a cell by autonomous replication or reintegration into the genome, effectively influencing copy number in cells. This has significant implications for cancer, where oncogenes are frequently amplified on eccDNA. However, little is known about the exact molecular mechanisms governing eccDNA functionality. To this end, we constructed a fluorescent reporter at an eccDNA-prone locus of the yeast genome, CUP1. It is our hope that this reporter will contribute to a better understanding of eccDNA formation and amplification within a cell.
