Malignant Peripheral Nerve Sheath Tumor (Mpnst): An Overview With Emphasis On Pathology, Imaging And Management Strategies, Timothy C. Beer

Department of Neurosurgery Faculty Papers

Presentation: 20 slides

MPNSTs are rare malignancies that are classically associated with pre-existing plexiform neurofibromas in neurofibromatosis type 1 (NF-1) patients, but also occur in association with radiation as well as sporadically in patients with no known risk factors. The typical presentation of sporadic MPNST is a new painless enlarging mass. The typical presentation of MPNST in an NF-1 patient is rapid enlargement or new onset of pain associated with a pre-existing plexiform neurofibroma. Although both MPNST and benign neurofibromas share in common the absence of neurofibromin function due to loss of both NF-1 alleles, malignant transformation to MPNST requires …

Narrative Health Communication And Behavior Change: The Influence Of Exemplars In The News On Intention To Quit Smoking., Hyun Suk Kim, Cabral A. Bigman, Amy E. Leader, Caryn Lerman, Joseph N. Cappella

Department of Medical Oncology Faculty Papers

This study investigated psychological mechanisms underlying the effect of narrative health communication on behavioral intention. Specifically, the study examined how exemplification in news about successful smoking cessation affects recipients' narrative engagement, thereby changing their intention to quit smoking. Nationally representative samples of U.S. adult smokers participated in 2 experiments. The results from the 2 experiments consistently showed that smokers reading a news article with an exemplar experienced greater narrative engagement compared to those reading an article without an exemplar. Those who reported more engagement were in turn more likely to report greater smoking cessation intentions.

Clean Needles And Bad Blood: Needle Exchange As Morality Policy, Elizabeth A. Bowen

The Journal of Sociology & Social Welfare

The morality policy framework is a lens for understanding the unique characteristics of policies that attempt to regulate personal morals and behaviors. Needle exchange, a controversial intervention for reducing the transmission of HIV in injection drug users, shares many of the hallmark characteristics of morality policies. Analyzing needle exchange from a morality policy perspective, focusing on the 21-year ban on federal funding for needle exchange, reveals how value-based arguments have been used in the needle exchange debate and explains why the issue is likely to remain controversial in the United States. This analysis adds to the understanding of moral and …

Exploring Barriers To Inclusion Of Widowed And Abandoned Women Through Microcredit Self-Help Groups: The Case Of Rural South India, Margaret Lombe, Chrisann Newransky, Karen Kayser, Paul Mike Raj

The Journal of Sociology & Social Welfare

Microcredit programs have been applauded as the magic bullet for the poor, especially women with limited financial resources. Building on previous research, this study examines effects of a microcredit self-help group (SHG) program on perceptions of social exclusion among widowed and abandoned women who participated in groups established after the 2004 Indian Ocean Tsunami in Tamil Nadu, India (N=109). Data were collected on key aspects of the program such as loan amount and investment patterns, group experience, demographics, and perceived barriers to inclusion. Results indicate that investment patterns and group experience impacted the women's perception of barriers to social inclusion. …

Glutathione-Mediated Neuroprotection Against Methylmercury Neurotoxicity In Cortical Culture Is Dependent On Mrp1, Travis Rush, Xiaoqian Liu, Andrew B. Nowakowski, David H. Petering, Doug Lobner

Biomedical Sciences Faculty Research and Publications

Methylmercury (MeHg) exposure at high concentrations poses significant neurotoxic threat to humans worldwide. The present study investigated the mechanisms of glutathione-mediated attenuation of MeHg neurotoxicity in primary cortical culture. MeHg (5 μM) caused depletion of mono- and disulfide glutathione in neuronal, glial and mixed cultures. Supplementation with exogenous glutathione, specifically glutathione monoethyl ester (GSHME) protected against the MeHg induced neuronal death. MeHg caused increased reactive oxygen species (ROS) formation measured by dichlorodihydrofluorescein (DCF) fluorescence with an early increase at 30 min and a late increase at 6 h. This oxidative stress was prevented by the presence of either GSHME or …

Near Infrared Spectroscopic Monitoring During Cardiopulmonary Exercise Testing Detects Anaerobic Threshold, Rohit P. Rao, Michael J. Danduran, J. E. Dixon, Rohit S. Loomba, George M. Hoffman

Exercise Science Faculty Research and Publications

Cardiopulmonary exercise testing (CPET) provides assessment of the integrative responses involving the pulmonary, cardiovascular, and skeletal muscle systems. Application of exercise testing remains limited to children who are able to understand and cooperate with the exercise protocol. Near-infrared spectroscopy (NIRS) provides a noninvasive, continuous method to monitor regional tissue oxygenation (rSO2). Our specific aim was to predict anaerobic threshold (AT) during CPET noninvasively using two-site NIRS monitoring. Achievement of a practical noninvasive technology for estimating AT will increase the compatibility of CPET. Patients without structural or acquired heart disease were eligible for inclusion if they were ordered to undergo CPET …

Roles Of Resveratrol And Genistein In Invasion And Metastasis Of Breast Cancer, Brittany Wolfe

College of Science and Health Theses and Dissertations

Breast cancer is a cellular disease characterized by the exploitation of several cellular and molecular mechanisms involved in cell proliferation, apoptosis, motility, and invasion. Effective treatment is available for non-invasive breast cancer at diagnosis, leading to a very high survival rate compared to the low survival rate for those where the breast cancer has spread. Thus, identifying effective therapies and preventative agents is imperative to successfully treat breast cancer. Since diet compromises a large component of the risk factors for breast cancer, it would be beneficial to examine dietary compounds that could potentially play a beneficial role in inhibiting cancer …

Parenting Behaviors Of African American And Caucasian Families: Parent And Child Perceptions, Associations With Child Weight And Ability To Identify Abnormal Weight Status, Michele Polfuss, Marilyn Frenn

College of Nursing Faculty Research and Publications

This study examined the agreement between parent and child perceptions of parenting behaviors, the relationship of the behaviors with the child's weight status, and the ability of the parent to correctly identify weight status in 176 parent–child dyads (89 Caucasian and 87 African American). Correlational and regression analyses were used. Findings included moderate to weak correlations in child and parent assessments of parenting behaviors. Caucasian dyads had higher correlations than African American dyads. Most parents correctly identified their own and their child's weight status. Parents of overweight children used increased controlling behaviors, but the number of controlling behaviors decreased when …

Post-Abortion Care Family Planning Use In Pakistan, Syed Khurram Azmat, Waqas Hameed, Muhammad Ishaque, Ghulam Mustafa, Aftab Ahmed

Community Health Sciences

Introduction: The stagnated CPR and high unmet need for contraception lead to approximately 890,000 induced abortions every year in Pakistan. A fairly recent study from Pakistan also revealed that around 40% of abortions are performed by unskilled workers in backstreet clinics. Considering these grave statistics, it should not come as surprise that unwanted pregnancies are the leading cause of induced abortions in Pakistan. Despite country's inferior situation, there is no data available in Pakistan that unveils the much needed information pertaining to post-abortion care family planning (PAC) use. Thus, this paper attempts to document socio-demographic profile seeking post-abortion care clients; …

Research Brief: "Employment Outcomes And Ptsd Symptom Severity", Institute For Veterans And Military Families At Syracuse University

Institute for Veterans and Military Families

This study investigates how the severity of PTSD symptoms relates to employment and earnings. It found that veterans with more severe symptoms of PTSD were more likely to work part-time or not at all rather than have full-time work. In practice, treating PTSD, even if some symptoms remain, could result in better employment outcomes for veterans. In policy, policymakers should consider providing previously successful programs focused on veterans with PTSD for individuals with other mental health conditions. Suggestions for future research include a large, controlled, longitudinal survey that would allow researchers to investigate more thoroughly how PTSD symptoms relate to …

Brain Mapping Of The Mismatch Negativity Response In Vowel Formant Processing, Elizabeth Anne Perry

Theses and Dissertations

The mismatch negativity (MMN) response, a passively-elicited component of the auditory event-related potential (ERP), reflects preattentive identification of infrequent changes in acoustic stimuli. In the current study, the MMN response was examined closely to determine what extent natural speech sounds evoke the MMN. It was hypothesized that a significant MMN response results during the presentation of deviant stimuli from which spectral energy within formant bands critical to vowel identification has been removed. Localizations of dipoles within the cortex were hypothesized to yield information pertaining to the processing of formant-specific linguistic information. A same/different discrimination task was administered to 20 adult …

Stress, Coping And Suicide Ideation In Chinese College Students, Xiaoyun Zhang, Haiping Wang, Yan Ruth Xia, Xiaohong Liu, Eunju Jung

Department of Child, Youth, and Family Studies: Faculty Publications

The study was to examine 1) whether stress and coping styles could significantly predict the probability of suicide ideation; 2) and whether coping styles were mediators or moderators on the association between life stress and suicide ideation. The survey was conducted in a sample of 671 Chinese college students. Approximately twenty percent students reported having suicide ideation. Life stress, active coping styles, and passive coping styles all had independent effect on the probability of suicide ideation. Passive coping styles, especially fantasizing, mediated the relation between life stress and suicide ideation. Moderation hypotheses were not supported. Implications of the findings and …

Proline-Rich Tyrosine Kinase 2 (Pyk2) Regulates Igf-I-Induced Cell Motility And Invasion Of Urothelial Carcinoma Cells, Marco Genua, Shi-Qiong Xu, Simone Buraschi, Stephen C. Peiper, Leonard G. Gomella, Antonio Belfiore, Renato V. Iozzo, Andrea Morrione

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The insulin-like growth factor receptor I (IGF-IR) plays an essential role in transformation by promoting cell growth and protecting cancer cells from apoptosis. We have recently demonstrated that the IGF-IR is overexpressed in invasive bladder cancer tissues and promotes motility and invasion of urothelial carcinoma cells. These effects require IGF-I-induced Akt- and MAPK-dependent activation of paxillin. The latter co-localizes with focal adhesion kinases (FAK) at dynamic focal adhesions and is critical for promoting motility of urothelial cancer cells. FAK and its homolog Proline-rich tyrosine kinase 2 (Pyk2) modulate paxillin activation; however, their role in regulating IGF-IR-dependent signaling and motility in …

Perk-Dependent Repression Of Mir-106b-25 Cluster Is Required For Er Stress-Induced Apoptosis., S. Gupta, D. E. Read, A. Deepti, K. Cawley, A. Gupta, D. Oommen, T. Verfaillie, S. Matus, Mary A. Smith, Justin L. Mott, P. Agostinis, C. Hetz, A. Samali

Journal Articles: Biochemistry & Molecular Biology

Activation of the unfolded protein response sensor PKR-like endoplasmic reticulum kinase (Perk) attenuates endoplasmic reticulum (ER) stress levels. Conversantly, if the damage is too severe and ER function cannot be restored, this signaling branch triggers apoptosis. Bcl-2 homology 3-only family member Bim is essential for ER stress-induced apoptosis. However, the regulatory mechanisms controlling Bim activation under ER stress conditions are not well understood. Here, we show that downregulation of the miR-106b-25 cluster contributes to ER stress-induced apoptosis and the upregulation of Bim. Hypericin-mediated photo-oxidative ER damage induced Perk-dependent cell death and led to a significant decrease in the levels of …
