Utilizing Fast Spin Echo Mri To Reduce Image Artifacts And Improve Implant/Tissue Interface Detection In Refractory Parkinson’S Patients With Deep Brain Stimulators, Subhendra N. Sarkar, Pooja R. Sarkar, Efstathios Papavassiliou, Rafael Rojas

Publications and Research

Introduction. In medically refractory Parkinson’s disease (PD) deep-brain stimulation (DBS) is an effective therapeutic tool. Postimplantation MRI is important in assessing tissue damage and DBS lead placement accuracy. We wanted to identify which MRI sequence can detectDBS leads with smallest artifactual signal void, allowing better tissue/electrode edge conspicuity.

Methods. Using an IRB approved protocol 8 advanced PDpatientswere imagedwithinMRconditional safety guidelines at lowRF power (SAR ≤ 0.1 W/kg) in coronal plane at 1.5T by various sequences.The image slices were subjectively evaluated for diagnostic quality and the lead contact diameters were compared to identify a sequence least affected by metallic leads.

Vaccine-Preventable Diseases In Travelers, Edith Mirzaian, Jeffery A. Goad, Ani Amloian, Fady Makar

Pharmacy Faculty Articles and Research

Travel to the developing world is increasing among those from developed countries, placing them at risk for vaccine preventable and non-vaccine preventable diseases. From 2007-2011, the GeoSentinel Network reported 737 returned travelers with a vaccine preventable disease. While it is essential that clinicians use vaccines when available for a disease of risk, they should also be aware that the vast majority of diseases acquired by travelers are non-vaccine preventable. The vaccine preventable diseases can be divided into routine travel vaccines, special travel vaccines and routine vaccines used for travel. The routine travel vaccines include Hepatitis A and B, typhoid; special …

Methods: This was a secondary analysis of sexual function measured before and 1 year after laparoscopic sacrocolpopexy in a group of 81 sexually active women participating in a randomized controlled trial comparing porcine dermis and polypropylene mesh. Sexual function was assessed using the short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). Responses to individual questions from the physical domain of the PISQ-12 were also analyzed. Additional information included the type of mesh material …

Predictive Validity Of A Training Protocol Using A Robotic Surgery Simulator, Patrick Culligan, Emil Gurshumov, Christa Lewis, Jennifer Priestley, Jodie Komar, Charbel Salamon

Jennifer L. Priestley

Background: Robotic surgery simulation may provide a way for surgeons to acquire specific robotic surgical skills without practicing on live patients. Methods: Five robotic surgery experts performed 10 simulator skills to the best of their ability, and thus, established expert benchmarks for all parameters of these skills. A group of credentialed gynecologic surgeons naive to robotics practiced the simulator skills until they were able to perform each one as well as our experts. Within a week of doing so, they completed robotic pig laboratory training, after which they performed supracervical hysterectomies as their first-ever live human robotic surgery. Time, blood …

Detection Of Homocysteine With Bridged Viologen Chemical Probes, Davin Rautiola

Dissertations and Theses

Increased blood plasma concentrations of the aminothiol homocysteine (Hcy) are associated with a variety of disease states including those which cause impaired renal function, many forms of cardiovascular disease, and neurodegenerative diseases such as Alzheimer's. Therefore, Hcy has the potential to be a significant diagnostic biomarker. Routine monitoring of Hcy plasma concentration is encumbered by the time and resources required to quantify Hcy using currently accepted instrumental analysis methods. As part of the continuing effort to develop a quick, reliable, inexpensive, and user-friendly test to quantify Hcy at the point of care, we have designed a series of novel colorimetric …

Acute kidney injury (AKI) research in the past decade has mostly focused upon development of a standard AKI definition, validation of early novel biomarkers to predict AKI prior to serum creatinine rise and predict AKI severity, and assessment of aspects of renal replacement therapies and their impact on survival. Given the independent association between AKI and mortality in the acute phase, such focus makes imminent sense. More recently, the recognition that AKI is associated with subsequent development of chronic kidney disease and end-stage renal disease, with the attendant increase in mortality, has led to interest in the clinical epidemiology and …

Faculty Publications & Research of the TUC College of Osteopathic Medicine

Purpose. Critical illnesses are assessed according to the sequential organ failure assessment (SOFA) and acute physiology and chronic health evaluation (APACHE) II. Circulating ischemia-modified albumin (IMA) is a biomarker generated under ischemic and oxidative conditions and may reflect disease severity in preoperative patients. This study investigated the correlations of IMA with SOFA and APACHE II scores in inpatients admitted for colorectal surgery. Methods.We examined 27 patients with advanced colorectal cancers (mean age 69 years, men/women = 15/12). Correlations between SOFA and APACHE II scores in addition to preoperative serum IMA and C-reactive protein (CRP) levels were analyzed. Results …

The Efficacy And Safety Of The Human Papillomavirus Vaccine, Gail Tessler

The Science Journal of the Lander College of Arts and Sciences

The HPV virus is said to be the cause of many infections, warts, and cancers. In addition to the fact that the treatment for HPV is not always successful, not every individual knows that s/he is infected and is very likely to infect his or her partner, too. This is one factor that explains why 14 million people each year in America alone contract HPV and makes cervical cancer so threatening to many people worldwide. In light of this and the known dangers of cervical, anal, vaginal and penile cancers, the HPV vaccine was created to prevent an infection of …

The Search For Novel Inhibitors Of The Mycobacterial Enoyl Reductase Inha, Esther Saul

The Science Journal of the Lander College of Arts and Sciences

Isoniazid (INH), one of two first-line drugs used to treat tuberculosis (TB), has been shown to be a potent inhibitor of InhA, the mycobacterial enoyl reductase. However, the increasing resistance to INH makes it imperative to find alternative drugs that are as effective as the first-line drugs, yet active against INH-resistant strains. Since InhA has been validated as an excellent target of TB, there have been attempts to find novel inhibitors of InhA. Through rational drug design, a variety of high affinity InhA inhibitors were synthesized. Triclosan itself was observed to be a suboptimal inhibitor of InhA with a K …

Stem Cells As A Cure For Amyotrophic Lateral Sclerosis, Chaya K. Hirsch

The Science Journal of the Lander College of Arts and Sciences

Amyotrophic Lateral Sclerosis (ALS) is a fatal motor neuron disease which affects approximately 30,000 Americans at any given time (alsa.org, 2010). The etiology of this terminal disease unfortunately remains an unsolved mystery and has therefore severely limited the ability to find a cure. The use of stem cells to regenerate neurons has been vastly studied and have produced very promising results. However, its practicality as a cure or treatment for neurodegenerative diseases, such as ALS, is greatly compromised. Three different therapies involving stem cells were examined, Embryonic Stem Cells (ESC), induced pluripotent stem cells, (iPSC) and direct reprogramming of adult …

Apoptotic Neurodegeneration In The Developing Human Brain: Possible Role Of General Anesthetics In Its Genesis, And Of L-Carnitine In Its Reversal, Yisroel Yitzchok Rosenfeld

The Science Journal of the Lander College of Arts and Sciences

Recent studies suggest that general anesthetic (GA) agents administered to developing rats, through its mechanism as an NMDA antagonist or a GABAa mimetic, may damage developing neural cells by inducing a higher rate of programmed cell death (apoptosis). Similar heightened degeneration was also apparent in higher primates such as the monkey. This warrants strong concern, as every year thousands of pregnant women and children below 1 year of age undergo a surgical procedure in which GAs are used. A spike in neuroapoptosis may lead to long term cognitive deficiencies lingering into adulthood. Are humans vulnerable to these affects? Different pathways …

Biomarkers In Nsclc Epidermal Growth Factor Receptor Mutations, Suzanne Freidman

The Science Journal of the Lander College of Arts and Sciences

Lung Cancer is the most common global cause of cancer related deaths in men and women (Markus, Alain, 2013). As standard radiation and chemotherapy have proved ineffective, novel target therapies are in the midst of development. This review will analyze the success of the inhibitor drugs targeting the Epidermal Growth Factor Receptor (EGFR) mutation, commonly found amongst Lung Cancer patients. Numerous studies and reviews are utilized to determine the cause of the 10% success rate currently exhibited for these drugs. The L858R and E746-A750 point mutations and deletions respectively, were found prevalent in responsive patients as well as clinical-pathological features …
