Transdermal Delivery Of Drugs With Microneedles—Potential And Challenges, Kevin B. Ita

Faculty Publications & Research of the TUC College of Pharmacy

Transdermal drug delivery offers a number of advantages including improved patient compliance, sustained release, avoidance of gastric irritation, as well as elimination of pre-systemic first-pass effect. However, only few medications can be delivered through the transdermal route in therapeutic amounts. Microneedles can be used to enhance transdermal drug delivery. In this review, different types of microneedles are described and their methods of fabrication highlighted. Microneedles can be fabricated in different forms: hollow, solid, and dissolving. There are also hydrogel-forming microneedles. A special attention is paid to hydrogel-forming microneedles. These are innovative microneedles which do not contain drugs but imbibe interstitial …

Am. 133, 283–300 (2013)] are extended, with sensitivity improving by nearly another factor of 2. This result is obtained using a “quasi-optimal” reference waveform in the computation of the joint entropy imaging technique used to image the accumulating nanoparticles.

Dysregulation Of Micrornas In Blood As Biomarkers For Diagnosing Prostate Cancer, Rhonda W. Daniel

Theses and Dissertations

Prostate cancer is the most common noncutaneous cancer among men, yet current diagnostic methods are insufficient and more reliable diagnostic markers need to be developed. The answer that can bridge this gap and enable more efficient diagnoses may lie in microRNAs. These small, single stranded RNA molecules impact protein expression at the translational level and regulate important cellular pathways. Dysregulation of these small RNA molecules can have tumorigenic effects on cells and lead to many types of cancers.

Currently the Prostate-Stimulating Antigen (PSA) is used as a diagnostic marker for prostate cancer. However, many factors can elevate PSA levels such …

Analysis Of Protein Expression For Potential Biomarkers In Human Pancreatic Tumor Cell Lines, Jade Ashley Simpson

Honors Program Theses

Pancreatic cancer is an aggressive cancer of the pancreas that has been shown to have extremely low survival rates. It can be quite lethal because of its asymptomatic early stages and inability to detect cancer at the cellular level. Once diagnosed, the cancer will have usually spread or metastasized beyond surgical resection. Thus, research is focused on finding potential biomarkers in tumor cell lines to help in earlier diagnosis of this disease leading to better treatment options. Previous work using bioinformatics data suggest several cellular genes including, CTHCR1, EPPK1, AHNAK2, and IGHG3, can be potential biomarkers for pancreatic cancer. The …

Drug Interactions With Glutaredoxin Orthologues, Kahlilah R. Napper, Thomas C. Leeper, Ram Khattri, Daniel Morris, Caroline Davis

Williams Honors College, Honors Research Projects

Glutaredoxin, an enzymatic protein, is an important component of cell viability and function. It catalyzes reactions involved in DNA synthesis and innate immunity [1,4]. Glutaredoxin is also essential in antibiotic resistance in pathogenic bacterial species. Pseudomonas aeruginosa in particular is responsible for infecting the lung tissue of its human hosts, resulting in the development of pneumonia and cystic fibrosis [3]. Because glutaredoxin is pertinent in cell proliferation of eukaryotic and bacterial cells alike, medicinal fragments that take advantage of the subtle differences in protein structure of the orthologous proteins can be synthesized and enhanced to bind bacterial glutaredoxins, without inhibiting …

Functional Transcranial Doppler Ultrasound For High Temporal Resolution Measurement Of Lateralization In Visual Memory And Visual Search Cognitive Tasks, B. Hage, M. Alwatban, E. Barney, M. Mills, M. Dodd, E. Truemper, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Functional transcranial Doppler ultrasound (fTCD) is a noninvasive sensing modality that measures blood flow velocities in cerebral arteries (CBFV) with high temporal resolution. Few studies have examined the relationship of CBFV change during visual search and visual memory cognitive tasks. Here a protocol to compare lateralization between these two similar tasks using fTCD is demonstrated. Thirteen healthy volunteers were shown visual scenes on a computer and performed visual search and visual memory tasks while CBFV in the bilateral middle cerebral arteries was monitored with fTCD. Each subject completed 40 trials, consisting of baseline, calibration, instruction, and task periods. Lateralization was …

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

In this study we examined differences in fMRI activation and deactivation patterns during episodic verbal memory encoding between individuals with MCI (n = 18) and healthy controls (HCs) (n = 17). Participants were scanned in two different sessions during the application of self-initiated or directed instructions to apply semantic strategies at encoding of word lists. MCI participants showed reduced free recall scores when using self-initiated encoding strategies that were increased to baseline controls' level after directed instructions were provided. During directed strategic encoding, greater recruitment of frontoparietal regions was observed in both MCI and control groups; group differences …

The Need For Theory To Guide Concussion Research, Dennis Molfese

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

While the focus on concussion research has expanded greatly over the past decade, progress in identifying the mechanisms and consequences of head injury, the recovery path and the development of potential interventions to facilitate recovery have been largely absent. Instead, the field has largely progressed through an accumulation of data without the guidance of any systematic theory to guide the formulation of research questions or generate testable hypotheses. As part of this special issue on sports concussion, we advance a theory to describe the evolution of a neural network during the development of a cognitive process as well as the …

Topics include the evolution of AAC-based supports as they relate to people with aphasia, the development and key features of visual scene displays (VSDs), and future directions concerning the incorporation of photographs into communication supports for people with …

The Feasibility Of Implementing A Novel Electrical Stimulation Device In The Self-Management Of Hand Burn Pain, Katrina Liddiard

Theses : Honours

Burns are widely acknowledged as one of the most painful injuries experienced, and poorly controlled pain following burn injury has been linked to reduced psychological adjustment, lower quality of life, and increased risk of developing a chronic pain state. Transcutaneous electrical nerve stimulation has been used for pain relief in a range of medical conditions, and may have the potential to reduce pain and analgesic consumption for burns patients. The burn care environment presents unique challenges to the introduction of new interventions, and the feasibility of introducing a novel form of electrical stimulation into this environment has not been tested. …

Cell-based strategies represent a new frontier in the treatment of immune-mediated disorders. However, the paucity of markers for isolation of molecularly defined immunomodulatory cell populations poses a barrier to this field. Here, we show that ATP-binding cassette member B5 (ABCB5) identifies dermal immunoregulatory cells (DIRCs) capable of exerting therapeutic immunoregulatory functions through engagement of programmed cell death 1 (PD-1). Purified Abcb5+ DIRCs suppressed T cell proliferation, evaded immune rejection, homed to recipient immune tissues, and induced Tregs in vivo. In fully major-histocompatibility-complex-mismatched cardiac allotransplantation models, allogeneic DIRCs significantly prolonged allograft survival. Blockade of DIRC-expressed PD-1 reversed the inhibitory effects of …

Segmental Musculoskeletal Examinations Using Dual-Energy X-Ray Absorptiometry (Dxa): Positioning And Analysis Considerations, Nicolas H. Hart, Sophia Nimphius, Tania Spiteri, Jodie L. Cochrane, Robert U. Newton

Research outputs 2014 to 2021

Musculoskeletal examinations provide informative and valuable quantitative insight into muscle and bone health. DXA is one mainstream tool used to accurately and reliably determine body composition components and bone mass characteristics in-vivo. Presently, whole body scan models separate the body into axial and appendicular regions, however there is a need for localised appendicular segmentation models to further examine regions of interest within the upper and lower extremities. Similarly, in-consistencies pertaining to patient positioning exist in the litera-ture which influence measurement precision and analysis out-comes highlighting a need for standardised procedure. This paper provides standardised and reproducible: 1) positioning and analysis …

Defining Young In The Context Of Prostate Cancer, Suzanne Chambers, Anthony Lowe, Melissa Hyde, Leah Zajdlewicz, Robert F. Gardiner, David Sandoe, Jeff Dunn

Research outputs 2014 to 2021

The experience of prostate cancer is for most men a major life stress with the psychological burden of this disease falling more heavily on those who are younger. Despite this, being young as it applies to prostate cancer is not yet clearly defined with varied chronological approaches applied. However, men’s responses to health crises are closely bound to life course and masculinities from which social roles emerge. This paper applied qualitative methodology (structured focus groups and semistructured interviews with expert informants) using interpretative phenomenological analysis to define what it means to be young and have prostate cancer. Structured focus groups …
