Development Of A Sonically Powered Biodegradable Nanogenerator For Bone Regeneration, Avi Patel

Honors Scholar Theses

Background: Reconstruction of bone fractures and defects remains a big challenge in orthopedic surgery. While regenerative engineering has advanced the field greatly using a combination of biomaterial scaffolds and stem cells, one matter of difficulty is inducing osteogenesis in these cells. Recent works have shown electricity’s ability to promote osteogenesis in stem cell lines when seeded in bone scaffolds; however, typical electrical stimulators are either (a) externally housed and require overcomplex percutaneous wires be connected to the implanted scaffold or (b) implanted non-degradable devices which contain toxic batteries and require invasive removal surgeries.

Objective: Here, we establish a biodegradable, piezoelectric …

Seeing Eye To Eye: A Machine Learning Approach To Automated Saccade Analysis, Maigh Attre

Honors Scholar Theses

Abnormal ocular motility is a common manifestation of many underlying pathologies particularly those that are neurological. Dynamics of saccades, when the eye rapidly changes its point of fixation, have been characterized for many neurological disorders including concussions, traumatic brain injuries (TBI), and Parkinson’s disease. However, widespread saccade analysis for diagnostic and research purposes requires the recognition of certain eye movement parameters. Key information such as velocity and duration must be determined from data based on a wide set of patients’ characteristics that may range in eye shapes and iris, hair and skin pigmentation [36]. Previous work on saccade analysis has …

Distribution And Localization Of Novel Iodine Nanoparticles In The Human Glioma 1242 Growing In The Brains Of Mice, Benjamin Billings

Honors Scholar Theses

Observing and designing the in vivo distribution and localization of therapeutic nanoparticles is an essential aspect of developing and understanding novel nanoparticle- based medical treatments. This study investigates novel PEGylated Iodine-based nanoparticles (INPs), an alternate composition to the more widely researched gold nanoparticles (AuNPs), which may help avoid adverse effects associated with AuNPs, such as potential toxicity and skin discoloration, when used in similar applications. Determining the localization of the novel INPs within murine brains containing human glioma U-1242MG cells is critical in assisting the development of radiation dose enhancement therapy for this aggressive cancer. Radiation dose enhancement utilizes the …

The Agile Approach In Pharmaceutical Software Development, Priyal Bhargava

Honors Scholar Theses

The Agile development model is increasingly being adopted by the pharmaceutical industry for software development. Currently, there are several software projects under development by pharmaceutical companies that are using the Agile process. Other methodologies such as the Waterfall process, a traditional approach to project management, have evolved over time and been compared against the Agile method. Also there are conflicts of interest which should be taken into consideration when in a pharmaceutical setting such as abiding by FDA regulations. In addition, Agile’s sub-divisional approaches add to the versatility of how this iterative approach is applied in the pharmaceutical industry. The …

Design Of Exercise Equipment For Wheelchair Users: A Case Study In Accessibility Standards, Kate Craddock Rescsanszky

Honors Scholar Theses

Engineers must consider a number of aspects of every project they work on. Accessibility is one aspect that presents a unique challenge. Rather than being based on absolute material parameters, accessibility is based on how people interact with technology and their built environment. Since 1990, the Americans with Disabilities Act has been the predominant standard in accessibility because of its wide reach and legal mandate. In addition to the ADA, the ASTM and the Institute for Universal Design offer helpful guidelines for designing for accessibility. However, in addition to standards, guidelines, and recommendations, it is important to consult the intended …
