Joint Coordination Variability In Anterior Cruciate Ligament Reconstructed Subjects During Stair Ambulation Using A Vector Coding Technique, Bryan R. Simrak
Joint Coordination Variability In Anterior Cruciate Ligament Reconstructed Subjects During Stair Ambulation Using A Vector Coding Technique, Bryan R. Simrak
Theses and Dissertations (ETD)
Anterior cruciate ligament (ACL) rupture is a common injury, with an estimated incidence of 120,000 to 200,000 per year in the United States. ACL reconstruction surgery is the standard treatment for this injury to restore knee joint stability and function. While surgical reconstruction has been shown to restore laxity of the knee, current literature lacks consensus on return to normal knee joint kinematics following surgery. Additionally, re-injury is a major risk for those who return to sports activity after reconstruction surgery. Dynamical systems methods for quantifying joint coordination variability have been explored as a method for detecting differences between ACL …

Analytical Models Of Neutron Spectral Fluence, Kerma And Absorbed-Dose For Proton Therapy, Suman Shrestha
Analytical Models Of Neutron Spectral Fluence, Kerma And Absorbed-Dose For Proton Therapy, Suman Shrestha
LSU Master's Theses
Abstract
Purpose: The accurate prediction of stray neutron dose has become increasingly important as it increases the risk of second cancer development after proton therapy. Previously reported analytical models predicted the quantity dose equivalent, which includes physical and biological considerations but does not explicitly take into account material dependence and variation in the radiation quality. The purpose of this study was to investigate the feasibility of an analytical model of absorbed dose to water from stray neutrons in proton therapy.
Methods: To calculate neutron absorbed dose and kerma in water, the authors developed analytical models of neutron spectral fluence and …
Characterization Of Theranostic Peptides For Glioblastoma Multiforme, Aaron Mellesmoen
Characterization Of Theranostic Peptides For Glioblastoma Multiforme, Aaron Mellesmoen
All NMU Master's Theses
Glioblastoma multiforme (GBM) is a type of primary CNS tumor in which viable treatment options do not exist. Standard of care including tumor resection, chemotherapy, and radiation does little to extend the 5-year survival expectancy past 5.1%. Herein, two small-peptide molecules with inherent antitumor activity, blood-brain barrier permeability, and capability for tumor-specific drug deliverance and intraoperative visualization (termed theranostic) were of focus. Confocal microscopy was employed to characterize in vitro specificity of chlorotoxin, a 4 kDa scorpion venom peptide, and rBSG, the recombinant 25 kDa non-glycosylated extracellular domain of extracellular matrix metalloproteinase inducer (EMMPRIN; Basigin) isoform …
Simvastatin Does Not Sensitize Ibc3 Her2+ Inflammatory Breast Cancer Brain Metastases To Whole Brain Irradiation In An Immunocompromised Mouse Model, Swaminathan Kumar
Simvastatin Does Not Sensitize Ibc3 Her2+ Inflammatory Breast Cancer Brain Metastases To Whole Brain Irradiation In An Immunocompromised Mouse Model, Swaminathan Kumar
Dissertations & Theses (Open Access)
Retrospective data analysis suggests that inflammatory breast cancer (IBC) patients who take statins have better locoregional control after radiotherapy than those who do not [23]. Our lab has previously demonstrated that simvastatin radiosensitizes IBC cells in vitro [23], and brain metastases have strong expression of cholesterol-regulation genes compared to lung metastases in vivo [unpublished]. Delaying whole-brain irradiation (WBI) beyond 21 days is insufficient to reduce the incidence of brain metastases (developed by injecting IBC3 cells through the tail vein) in our mouse model because even high rates of cell killing leave substantial cell volume in established metastases [unpublished].

Cognitive And Emotional Correlates Of Improved Gait Distance During The Course Of Physical Therapy Treatment For An Incomplete Spinal Cord Injury, Danielle Miller
Honors Theses
Objective
The focus of spinal cord injury rehabilitation over the past four decades has shifted from medical management to issuses that affect quality of life and community participation (Gómara- Toldrà, Sliwinski, & Dijkers, 2014). However, the care team for spinal cord injury patients still need to collaberate in order to design and implement interventions that result in maximum participation to provide an individual with a spinal cord injury an effective rehabilitation program. In order to create such a rehablitation program, the care team must know how certain psychological and cognitive aspects, such as depression and implict memory, are related to …

Precision Gene Therapy For Charcot-Marie-Tooth Disease: From Identifying Genetic Modifiers To Developing Allele-Specific Therapies, Kathryn H. Morelli Ph.D.
Electronic Theses and Dissertations
Charcot-Marie-Tooth Disease (CMT) is a clinically and genetically heterogeneous collection of inherited peripheral neuropathies generally characterized by progressive muscle atrophy, weakness, and loss of sensation in the distal extremities. This inherited disorder, for which there is currently no curative treatment, is the most common inherited disease of the peripheral nervous system, affecting 1:2,500 individuals worldwide.
Clinically, CMT is broadly divided into demyelinating (type 1) and axonal (type 2) forms. Although the clinical presentation can vary greatly in severity and progression within individual patients. Genetically, over 1,000 mutations in over 80 loci in the human genome have been linked to specific …
Failure Of Primary Total Knee Arthroplasty: Establishing A Baseline For Retrieval Analysis Using Well-Functioning Necropsy Specimens, Meredith Perkins
Failure Of Primary Total Knee Arthroplasty: Establishing A Baseline For Retrieval Analysis Using Well-Functioning Necropsy Specimens, Meredith Perkins
Theses and Dissertations (ETD)
Introduction. Total knee arthroplasty (TKA) is an effective treatment for end-stage osteoarthritis of the knee. While many patients have positive functional and pain outcomes following primary TKA, a subset of patients have suboptimal outcomes, such as unexplained pain or aseptic loosening of the implant components necessitating revision of the index procedure. The understanding of the exact etiology of these suboptimal outcomes of primary TKA is in its infancy. In order to elucidate the etiology of failure in primary TKAs, a baseline for the factors contributing to arthroplasty failure and dissatisfaction must first be established. The purpose of this study …

Maturation Of Human Induced Pluripotent Stem Cell Derived Engineered Cardiac Tissues Using Chief Transfection And Chronic Optical Pacing., Marc M. Dwenger
Maturation Of Human Induced Pluripotent Stem Cell Derived Engineered Cardiac Tissues Using Chief Transfection And Chronic Optical Pacing., Marc M. Dwenger
Electronic Theses and Dissertations
The immaturity of engineered cardiac tissues (ECTs) limits their ability to regenerate damaged myocardium and to serve as in vitro disease models and surrogates for drug toxicity testing. Several chronic biomimetic conditioning protocols, including mechanical stretch, perfusion, and electrical stimulation promote ECT maturation but have significant technical limitations. Non-contacting chronic light stimulation using heterologously expressed light-sensitive ChIEF ion channels, termed optogenetics, may be an advantageous alternative to chronic electrical stimulation. As a proof of principle, we transfected ECTs using an AAV packaged ChIEF and then verified acute optical pacing (OP) by patch clamp. We then chronically OP ECTs for 7 …
Paclitaxel Enhances Oncolytic Potential Of Herpes Simplex Virus Type-1 In Cancer Cells, Misagh Naderi
Paclitaxel Enhances Oncolytic Potential Of Herpes Simplex Virus Type-1 In Cancer Cells, Misagh Naderi
LSU Master's Theses
Taxanes are spindle poisons that bind to and stabilize microtubules resulting in mitotic arrest. Herpes simplex Typ-1 (HSV-1) virions utilize the microtubular network for intracellular transport during both virus entry and virus egress from infected cells. It has been reported previously that taxanes may synergize with oncolytic herpes simplex viruses in the treatment of experimental prostate and breast tumors in mice. Other reports have indicated that taxanes may inhibit viral replication in infected cells. In this study the previously characterized Oncolytic Herpes Simplex Virus type 1 (OSVP), which was constructed in Kousoulas lab was used in conjugation with paclitaxel (taxol) …
Discovery And Effects Of Pharmacological Inhibition Of The E3 Ligase Skp2 By Small Molecule Protein-Protein Interaction Disruptors, John K. Morrow
Discovery And Effects Of Pharmacological Inhibition Of The E3 Ligase Skp2 By Small Molecule Protein-Protein Interaction Disruptors, John K. Morrow
Dissertations & Theses (Open Access)
Skp2 (S-phase kinase-associated protein 2), one component of the SCF E3 ubiquitin ligase complex, directly interacts with Skp1 and indirectly associates with Cullin1 and Rbx1 to bridge the E2 conjugating enzyme with its protein substrate to execute its E3 ligase activity. Skp2 is an Fbox protein (due to it containing an Fbox domain) and it is the rate-limiting component of the SCF complex. Skp2 targets several cell-cycle regulatory proteins for ubiquitination and degradation; most notable and significant for cancer are the cyclin-dependent kinase inhibitor, p27. Skp2 is an oncogene and studies have shown that over-expression of Skp2 leads to increased …
A Comparison Of Hamstring Injury Recovery Rates In Male And Female Athletes, Amanda Hall
A Comparison Of Hamstring Injury Recovery Rates In Male And Female Athletes, Amanda Hall
Undergraduate Honors Theses
Excerpt from Introduction
Hamstring injuries are among the most common muscular injuries sustained by athletes across multiple levels of various sports (Askling et al). Most hamstring injuries occur during similar movements and under similar conditions, where the muscle is required to be explosive. Thus, athletes that participate in sports where “sprinting, kicking, or high-speed skilled movements” are required, experience an increased likelihood of suffering a hamstring injury (Erickson and Sherry). After injury, athletes are then subjected to different methods of rehabilitation to heal and strengthen the afflicted area. However, some athletes take longer than others to return and impatience may …

Targeted Delivery Of A Therapeutic Protein For The Treatment Of Alzheimer's Disease, Heather Holman
Targeted Delivery Of A Therapeutic Protein For The Treatment Of Alzheimer's Disease, Heather Holman
Honors Undergraduate Theses
Neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease are linked to mitochondrial dysfunction and the underexpression of TOM40, a protein with chaperone-like qualities that is responsible for transporting precursor proteins into the mitochondria. Overexpression of TOM40 is reported to partially restore mitochondrial dysfunction and decrease the accumulation of neurotoxic aggregates of α-synuclein. Our goal is to develop an effective method for delivery of TOM40 protein to the brain.
Previous studies have used lentiviruses to carry TOM40 into the hippocampus of α-synuclein transgenic mice. The disadvantage of lentiviral transfection is the random insertions of the target gene into the host …
Drug Delivery With Light, Patrick S. Dupart
Drug Delivery With Light, Patrick S. Dupart
Theses and Dissertations
Cancer is responsible for about 25% of deaths in developed countries and for 15% of all deaths worldwide. Cancer is a devastating disease and while there have been great advances in the development of anticancer drugs, off-target toxicity is a major limitation with conventional cancer chemotherapy. The consequence of this form of treatment results in the killing of healthy and rapidly-growing non-cancerous cells including cells in the bone marrow; hair follicles; and cells in the mouth, digestive tract, and reproductive system. In addition to these general effects, certain anticancer drugs can have other associated toxicities. For instance, the anticancer drug …

Investigation Of The Effects Of Cobimetinib On Neurofibromatosis Type 2 Model Schwannoma Cells, Konstantin Brnjos
Honors Undergraduate Theses
Neurofibromatosis type two (NF2) is a genetic disorder predisposing those affected to the development of multiple benign tumors in their central and peripheral nervous systems. This is due to the absence of the tumor suppressor protein merlin, which is encoded by the NF2 gene. In nearly all NF2 cases, patients present with bilateral schwannomas of the vestibulocochlear nerve, in addition to other schwannomas throughout the central and peripheral nervous systems, as well as meningiomas and ependymomas. Currently, no therapeutic alternatives to surgical removal and radiation therapy are available for NF2 patients. This study investigated cobimetinib, an inhibitor of the often-deregulated …

Glycosaminoglycan Lyases In The Preparation Of Oligosaccharides, Alhumaidi B. Alabbas
Glycosaminoglycan Lyases In The Preparation Of Oligosaccharides, Alhumaidi B. Alabbas
Theses and Dissertations
Glycosaminoglycans are heterogeneous polysaccharides that mediate important biological functions. There has been considerable interest in deciphering the precise GAG sequences that are responsible for protein interactions. In fact, several GAG oligosaccharides have been discovered to date as targeting proteins with higher level of specificity. Yet, it has been difficult to develop GAG oligosaccharides as drugs. One of the key reasons for this state of art is that GAG synthesis is extremely challenging and is highly structure-specific. Thus, much of the biology and pharmacology of GAG remains unknown and unexploited to date.
An alternative approach is to prepare GAG oligosaccharides using …
Development Of Methods To Modulate Natural Killer Cells, Kari A. Shaver
Development Of Methods To Modulate Natural Killer Cells, Kari A. Shaver
Honors Undergraduate Theses
Natural Killer (NK) cell based immunotherapies have demonstrated success against malignancies and hematological cancers. However, tumors have developed mechanisms to evade detection by and suppress the immune system, commonly through altering the expression of cell-surface proteins. Overexpression of human leukocyte antigen-E (HLA-E), which binds to the inhibitory NKG2A on NK cells, protects malignant cells from lysis. Downregulating the NKG2A receptor on NK cells should release NK cell inhibition, but proves challenging as NK cells are difficult to transfect and no good methods currently exist. This project is designed to investigate the use of exosomes – small vesicles and natural carriers …
