Can Meaningful Effective Connectivities Be Obtained Between Auditory Cortical Regions?, M S Gonçalves, D A Hall, Ingrid Johnsrude, M P Haggard

Brain and Mind Institute Researchers' Publications

Structural equation modeling (SEM) of neuroimaging data can be evaluated both for the goodness of fit of the model and for the strength of path coefficients (as an index of effective connectivity). SEM of auditory fMRI data is made difficult by the necessary sparse temporal sampling of the time series (to avoid contamination of auditory activation by the response to scanner noise) and by the paucity of well-defined anatomical information to constrain the functional model. We used SEM (i.e., a model incorporating latent variables) to investigate how well fMRI data in four adjacent cortical fields can be described as an …

The Effect Of Parental Divorce On Young Adult Women's Marital Attitudes, Anne Catherine Schmidt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examines how the experience of a parent's divorce during adolescence affects young adult women's attitudes about relationships, marriage and divorce.
Research questions looked at how participants felt about marriage, their relationship with their parents following the divorce, and how the experience of parental remarriage shapes attitudes about marriage. Fifteen young adult women were interviewed.

The most significant findings were that experiencing a parental divorce leads to
fee lings of ambivalence about marriage. Religious beliefs and positive role models can alleviate some of the negative feelings about marriage that may be present following a parental divorce. Experiencing parental conflict …

Department Of Radiation Oncology And Kimmel Cancer Center, Thomas Jefferson University, The Intronic G13964c Variant In P53 Is Not A High-Risk Mutation In Familial Breast Cancer In Australia., Anna Marsh, Amanda B Spurdle, Bruce C Turner, Sian Fereday, Heather Thorne, Gulietta M Pupo, Graham J Mann, John L Hopper, Joseph F Sambrook, Georgia Chenevix-Trench

Department of Radiation Oncology Faculty Papers

BACKGROUND: Mutations in BRCA1 and BRCA2 account for approximately 50% of breast cancer families with more than four affected cases, whereas exonic mutations in p53, PTEN, CHK2 and ATM may account for a very small proportion. It was recently reported that an intronic variant of p53--G13964C--occurred in three out of 42 (7.1%) 'hereditary' breast cancer patients, but not in any of 171 'sporadic' breast cancer control individuals (P = 0.0003). If this relatively frequent occurrence of G13964C in familial breast cancer and absence in control individuals were confirmed, then this would suggest that the G13964C variant plays a role in …

Eye Position Signal Modulates A Human Parietal Pointing Region During Memory-Guided Movements., J F Desouza, S P Dukelow, J S Gati, R S Menon, R A Andersen, T Vilis

Brain and Mind Institute Researchers' Publications

Using functional magnetic resonance imaging, we examined the signal in parietal regions that were selectively activated during delayed pointing to flashed visual targets and determined whether this signal was dependent on the fixation position of the eyes. Delayed pointing activated a bilateral parietal area in the intraparietal sulcus (rIPS), rostral/anterior to areas activated by saccades. During right-hand pointing to centrally located targets, the left rIPS region showed a significant increase in activation when the eye position was rightward compared with leftward. As expected, activation in motor cortex showed no modulation when only eye position changed. During pointing to retinotopically identical …

Navigation-Related Structural Change In The Hippocampi Of Taxi Drivers, E A Maguire, D G Gadian, Ingrid Johnsrude, C D Good, J Ashburner, R S Frackowiak, C D Frith

Brain and Mind Institute Researchers' Publications

Structural MRIs of the brains of humans with extensive navigation experience, licensed London taxi drivers, were analyzed and compared with those of control subjects who did not drive taxis. The posterior hippocampi of taxi drivers were significantly larger relative to those of control subjects. A more anterior hippocampal region was larger in control subjects than in taxi drivers. Hippocampal volume correlated with the amount of time spent as a taxi driver (positively in the posterior and negatively in the anterior hippocampus). These data are in accordance with the idea that the posterior hippocampus stores a spatial representation of the environment …

Ubinuclein, A Novel Nuclear Protein Interacting With Cellular And Viral Transcription Factors., S Aho, M Buisson, T Pajunen, Y W Ryoo, J F Giot, H Gruffat, A Sergeant, Jouni Uitto

Department of Dermatology and Cutaneous Biology Faculty Papers

The major target tissues for Epstein-Barr virus (EBV) infection are B lymphocytes and epithelial cells of the oropharyngeal zone. The product of the EBV BZLF1 early gene, EB1, a member of the basic leucine-zipper family of transcription factors, interacts with both viral and cellular promoters and transcription factors, modulating the reactivation of latent EBV infection. Here, we characterize a novel cellular protein interacting with the basic domains of EB1 and c-Jun, and competing of their binding to the AP1 consensus site. The transcript is present in a wide variety of human adult, fetal, and tumor tissues, and the protein is …

Intimate Partner Violence Among Men And Women In South Carolina, 1998, Ann L. Coker, Christina Derrick, Julia L. Lumpkin, Robert Oldendick, R H. Potter

CRVAW Faculty Journal Articles

Few studies provide population-based estimates of intimate partner violence (IPV) for men and women, especially at the state level. IPV may result in adverse health effects for victims and perpetrators (1-3). To estimate the lifetime incidence of IPV by type of violence (e.g., physical, sexual, and perceived emotional abuse) and to explore demographic correlates of reporting IPV among men and women, the South Carolina Department of Health and Environmental Control and the University of South Carolina conducted a population-based random-digit-dialed telephone survey of adults in the state. This report summarizes the results of the survey, which indicated that approximately 25% …

The Effects Of Free Fatty Acids On Gluconeogenesis And Glycogenolysis In Normal Subjects, X Chen, N Iqbal, G Boden

Rowan-Virtua School of Osteopathic Medicine Departmental Research

We have quantitatively determined gluconeogenesis (GNG) from all precursors, using a novel method employing 2H20 to address the question of whether changes in plasma free fatty acids (FFA) affect GNG in healthy, nonobese subjects. In the first study (n = 6), plasma FFA were lowered at 16 to 20 hours with nicotinic acid (NA) and were then allowed to rise at 20 to 24 hours (FFA rebound after administration of NA). FFA decreased from 387 microM at 16 hours to 43 microM at 20 hours, and then rebounded to 1,823 microM at 24 hours. GNG decreased from 58.1% at 16 …

Endemic foci of human African trypanosomiasis are present in southern Sudan. In 1996 and 1997, trypanosomiasis increased sharply in Tambura County. To define the magnitude and geographic distribution of the outbreak, we conducted a prevalence survey using population-based cluster sampling in 16 villages: 1,358 participants answered questions about routine activities and tsetse fly contact and received serologic testing. Seroprevalence in the surveyed area was 19.4% (95% confidence interval = 16.9%, 21.8%). We confirmed infection in 66% of seropositive persons who received one parasitologic examination and in 95% of those who had serial examinations of lymph node fluid and blood. Activities …

The Effects Of Two Teaching Methodologies On Knowledge Of Insulin Administration Practices In An Older Adult Group, Clara D.J. Pieh

MSN Research Projects

Approximately 11 million people are affected with acute and chronic complications of diabetes. An estimated $20 billion is spent annually on the diagnosis and management of diabetes. Client adherence to self-care practice is essential to the control of diabetes. The self-care practice of injecting insulin is imperative for the management of both patients with type 1 and type 2 diabetes. Teaching modalities which effectively increase patient knowledge about insulin administration need to be developed and implemented. Therefore, the purpose of this study was to determine whether individualized instructions or audiovisual instructions increased the knowledge of insulin administration practices in older …

How Do Hmos Achieve Savings? The Effectiveness Of One Organization's Strategies., Ann B. Flood, Allen M. Fremont, K Jin, David M. Bott

Dartmouth Scholarship

To examine how a group practice used organizational strategies rather than provider-level incentives to achieve savings for health maintenance organization (HMO) compared to fee-for-service (FFS) patients. A large group practice with a group model HMO also treating FFS patients. Data sources were all patient encounter records, demographic files, and clinic records covering 3.5 years (1986-1989). The clinic's procedures to record services and charges were identical for FFS and HMO patients. All FFS and HMO patients under age 65 who received any outpatient services during approximately 100,000 episodes of the seven study illnesses were eligible.

Identification Of Fetal Dna And Cells In Skin Lesions From Women With Systemic Sclerosis, Carol M. Artlett, J. Bruce Smith, Sergio A. Jimenez

Selected Works of Sergio Jiménez, MD, MACR

BACKGROUND: Systemic sclerosis is a disease of unknown origin which often occurs in women after their childbearing years. It has many clinical and histopathological similarities to chronic graft-versus-host disease. Recent studies indicate that fetal stem cells can survive in the maternal circulation for many years post partum. This finding suggests that fetal cells persisting in the maternal circulation or tissues could be involved in the pathogenesis of systemic sclerosis by initiating a graft-versus-host reaction.

METHODS: We used the polymerase chain reaction (PCR) to identify Y-chromosome sequences in DNA extracted from peripheral-blood cells and skin lesions from women with systemic sclerosis …

Identifying Global Anatomical Differences: Deformation-Based Morphometry, J Ashburner, C Hutton, R Frackowiak, Ingrid Johnsrude, C Price, K Friston

Brain and Mind Institute Researchers' Publications

The aim of this paper is to illustrate a method for identifying macroscopic anatomical differences among the brains of different populations of subjects. The method involves spatially normalizing the structural MR images of a number of subjects so that they all conform to the same stereotactic space. Multivariate statistics are then applied to the parameters describing the estimated nonlinear deformations that ensue. To illustrate the method, we compared the gross morphometry of male and female subjects. We also assessed brain asymmetry, the effect of handedness, and interactions among these effects.

Is Mammography Useful In Screening For Local Recurrences In Patients With Tram Flap Breast Reconstruction After Mastectomy For Multifocal Dcis?, A P Salas, M A Helvie, E G Wilkins, H A Oberman, P W Possert, Alan M. Yahanda Md, Facs, A E Chang

PCI Publications and Projects

BACKGROUND: Skin-sparing mastectomy with immediate transverse rectus abdominis musculocutaneous (TRAM) flap reconstruction is being used more often for the treatment of breast cancer. Mammography is not used routinely to evaluate TRAM flaps in women who have undergone mastectomy. We have identified the potential value of its use in selected patients.

METHODS AND RESULTS: We report on four women who manifested local recurrences in TRAM flaps after initial treatment for ductal carcinoma in situ (DCIS) or DCIS with microinvasion undergoing skin-sparing mastectomy and immediate reconstruction. All four patients presented with extensive, high-grade, multifocal DCIS that precluded breast conservation. Three of four …

Auditory Filters Measured At Neighboring Center Frequencies, Marc A. Fagelson, C. A. Champlin

ETSU Faculty Works

Auditory filters were derived in 20 normal-hearing human listeners at center frequencies (CFs) of 913, 1095, 3651, and 4382 Hz using the roex (p,r) method. Comparisons were made between slopes of the filters' skirts at the neighboring CFs with filter output levels of 45 and 70 dB. The same comparisons were made with regard to filter equivalent rectangular bandwidth (ERB). In the 1000-Hz region, the low-frequency slopes (Pl) of filters centered at 913 and 1095 Hz were significantly correlated at both stimulus levels, while the high-frequency slopes (Pu) were similar only at the high test level. In the 4000-Hz region, …
