Insole Antenna For On-Body Telemetry, Domenico Gaetano, Patrick Mcevoy, Max Ammann, Matthias John, Colm Brannigan, Louise Keating, Frances Horgan

Articles

A 433 MHz antenna is proposed for integration with the insole of footwear for a body area network. The folded dipole design with an asymmetric groundplane radiates from its edges and considers the close proximity of the human foot and ground surfaces. It functions for different ground conductivity conditions and an on-body communication link with an Inverted F Antenna in the upper body area was evaluated on a static and dynamic human subject. The antenna solution was compliant with Specific Absorption Rate requirements, remains matched and links with upper-body nodes regardless of the body posture and node location.

Functional Analysis Of The Molluscum Contagiosum Virus Mc160 Death Effector Domain-Containing Protein Rxdl Motif, Sarah Weber

Seton Hall University Dissertations and Theses (ETDs)

The Molluscum contagiosum virus (MCV) is a member of the Poxviridae family that causes benign skin lesions. MCV lesions persist on average for 8-12 months in otherwise healthy individuals. MCV lesions are characterized by reduced inflammation. The persistence and reduction of inflammation at the site of MCV lesions have been attributed to MCV immune evasion genes. MCV encodes two death effector domain (DED) containing proteins, MC159 and MC160. DEDs are found in cellular proteins such as FADD and procaspase-8. These cellular proteins are involved in several innate immune responses such as apoptosis and activation of interferon (IFN). Presumably, MC159 and …

A Study To Evaluate The Maximal Dose Administration At Two Different Locations In Two Different Vdr4 High Frequency Percussive Ventilator (Hpfv) Circuits, Jeff L. Heltborg, Bethany S. Kobza, Ace Nilson

Student Research Symposium

The purpose of this study was to determine if the positioning of a nebulizer at two different locations in the VDR4, a specialty ventilator, would result in differing dose administrations of a bronchodilator, Albuterol Sulfate. We hypothesized that placement near the endotracheal tube will provide greater dose deposition. The ventilator was set up to mimic the normal adult patient. Administration was done through the nebulizer placed in the ventilator circuit either before the humidifier or between the endotracheal tube and the VDR 4’s Phasitron. Three trials were performed using a standard dose of Albuterol for each trial. The mass of …

Fracture Toughness Of Irradiated Bone In A Murine Model, Lynda Marie Brady

Renée Crown University Honors Thesis Projects - All

Cancer is a prevalent and diverse disease affecting fourteen million people in the United Sates alone. While some cancers can be treated effectively with one-time operations such as surgery, other cancers require more persistent treatments, commonly chemotherapy and radiation. These latter two treatments can have extreme side-effects and long-term ramifications. One long-term side effect of radiation therapy is a higher incidence of insufficiency fractures in bones of the skeleton. The mechanism responsible for this apparent weakness in bone is not well understood. In order to quantify changes in ductility following radiation therapy, femora from mice treated with 20 Gy radiation …

Diabetes Type 2 Self-Management Education Program: Short Messaging From Patient Portal To Web-Enabled Device, Lynn S. Holcomb

The Effect Of An Educational Intervention On Oral Anticoagulation Therapy Knowledge In Primary Care, Elizabeth D. Deck

Evidence-Based Practice Project Reports

It is estimated that three million people in the United States are on oral anticoagulation therapy (warfarin). Populations studied have been found in therapeutic range 64% of the time (Pernod, Labarere, & Bosson, 2008). The low percentage of therapeutic range is attributable to (a) adherence, (b) monitoring infrequency, (c) Vitamin K antagonists, and (d) the effects of aging and comorbidities. The purpose of this evidence-based practice (EBP) project was to examine whether an educational intervention would improve the knowledge of patients receiving warfarin therapy. Roy’s model for patient adaptation and the Stetler Model for EBP were used as frameworks for …

Articles

Vibrational spectroscopy, including Raman spectroscopy, has been widely used over the last few years to explore potential biomedical applications. Indeed, Raman spectroscopy has been demonstrated to be a powerful non-invasive tool in cancer diagnosis and monitoring. In confocal microscopic mode, the technique is also a molecularly specific analytical tool with optical resolution which has potential applications in subcellular analysis of biochemical processes, and therefore as an in vitro screening tool of the efficacy and mode of action of, for example, chemotherapeutic agents.

In order to demonstrate and explore the potential in this field, established, model chemotherapeutic agents can be valuable. …

The Incidence Of Chagas Coinfections Amongst Acute Dengue Patients In Machala, Ecuador, Elizabeth A. Mcmahon

Renée Crown University Honors Thesis Projects - All

Dengue fever is a febrile illness found throughout the tropics that, in severe cases, can be deadly. The most rapidly spreading of any mosquito-borne disease, dengue is re-emerging as an illness of great concern in Latin America and around the globe. The CDC estimates that as many as 400 million cases of dengue occur each year. The pathogenesis of dengue virus is complicated and acts through modulation of the host immune system. Dengue polarizes the immune system balance of T helper 1 (Th1) and T helper 2 (Th2) cells towards a Th1 inflammatory response. Parasitic infections have also been shown …
