Introduction Of Healing Touch Into An Established Torture Treatment Center: A Graduate Field Project, Kathleen Mccullough-Zander

Theses and Graduate Projects

Healing Touch, an energetic treatment modality developed by nurses, was introduced into an established torture treatment center with the goal of decreasing torture-related symptoms and increasing survivors' overall sense of well-being and health. Three methods of evaluation were used to determine if the project goal had been met. The first project objective of showing a decrease in participants' reported feelings of anxiety and depression was not achieved. The second project objective of demonstrating a reduction in participant's reported levels of pain was achieved with statistically significant results. The third project objective of obtaining statements of recognition of the therapy as …

Long-Term Evaluation Of The Use Of The Transdermal Contraceptive Patch In Adolescents, Stephanie Logsdon, Jessica Richards, Hatim A. Omar

Pediatrics Faculty Publications

The transdermal contraceptive patch, Ortho Evra™, was approved in December 2001 and released on the market in June 2002. In this study, we reviewed clinical data of young women who started the patch between June 2002 and December 2003 in the adolescent medicine clinic at a university-based outpatient center. A total of 62 patients started the patch in that period and two of them were lost to follow-up. Mean age of patients was 17.9 years and mean length of use was 10 cycles. Only 10 patients (16.7%) discontinued use. Reasons for discontinuation were moderate to severe skin irritation (3 patients, …

Clinical Profiles, Occurrence, And Management Of Adolescent Patients With Hair-An Syndrome, Hatim A. Omar, Stephanie Logsdon, Jessica Richards

Pediatrics Faculty Publications

The syndrome of hyperandrogenism, insulin resistance, and acanthosis nigricans (HAIR-AN) is a subphenotype of the polycystic ovary syndrome. It is one of the most common causes of menstrual problems, hyperandrogenic symptoms, and insulin resistance among young women. Review of clinical data in an outpatient adolescent clinic showed that of the 1,002 young women (ages 10-21 years) attending the clinic over a 2-year period, 50 (5%) were diagnosed with HAIR-AN syndrome. Mean age of the patients was 15.5, initial mean weight at diagnosis was 94.5 kg, and the mean BMI was 33.33 kg/m2. Patients were treated with a weight-stabilization and -reduction …

Transcriptional Activation Of The Human Prostatic Acid Phosphatase Gene By Nf-Kappab Via A Novel Hexanucleotide-Binding Site., Stanislav Zelivianski, Richard Glowacki, Ming-Fong Lin

Journal Articles: Biochemistry & Molecular Biology

Human prostatic acid phosphatase (PAcP) is a prostate epithelium-specific differentiation antigen. Cellular PAcP functions as a neutral protein tyrosine phosphatase and is involved in regulating androgen-promoted prostate cancer cell proliferation. Despite the fact that the promoter of the PAcP gene has been cloned, the transcriptional factors that regulate PAcP expression remain unidentified. This article describes our analyses of the promoter of the PAcP gene. Deletion analyses of the promoter sequence up to -4893 (-4893/+87) revealed that a 577 bp fragment (-1356/-779) represents the unique positive cis-active element in human prostate cancer cells but not in HeLa cervix carcinoma cells. Interestingly, …

Flash Artifact Suppression In Two-Dimensional Ultrasound Imaging, Richard Yung Chiao, Gregory Ray Bashford, Mark Peter Feilen, Cynthia Andrews Owen

Biomedical Imaging and Biosignal Analysis Laboratory

Flash artifacts in ultrasound flow images are suppressed to achieve enhanced flow discrimination. Flash artifacts typically occur as region of elevated signal strength (brightness or equivalent color) within an image. A flash suppression algorithm included the steps of estimating the flash within an image and then suppressing the estimated flash. The mechanism for flash suppression is spatial filtering. An extension of this basic method used information from adjacent frames to estimate the flash and/or to smooth the resulting image sequence. Temporal information from adjacent frames is used as an adjunct to improve performance.

Probabilistic Disease Classification Of Expression-Dependent Proteomic Data From Mass Spectrometry Of Human Serum, Ryan H. Lilien, Hany Farid, Bruce R. Donald

Dartmouth Scholarship

We have developed an algorithm called Q5 for probabilistic classification of healthy vs. disease whole serum samples using mass spectrometry. The algorithm employs Principal Components Analysis (PCA) followed by Linear Discriminant Analysis (LDA) on whole spectrum Surface-Enhanced Laser Desorption/Ionization Time of Flight (SELDI-TOF) Mass Spectrometry (MS) data, and is demonstrated on four real datasets from complete, complex SELDI spectra of human blood serum.

Q5 is a closed-form, exact solution to the problem of classification of complete mass spectra of a complex protein mixture. Q5 employs a novel probabilistic classification algorithm built upon a dimension-reduced linear discriminant analysis. Our solution is …

Neuroanatomical Structure Of The Spinner Dolphin (Stenella Longirostris Orientalis) Brain From Magnetic Resonance Images, Lori Marino, Keith Sudheimer, William A. Mclellan, John I. Johnson

Veterinary Science and Medicine Collection

High-resolution magnetic resonance (MR) images of the brain of an adult spinner dolphin (Stenella longirostris orientalis) were acquired in the coronal plane at 55 antero-posterior levels. From these scans a computergenerated set of resectioned virtual images in the two remaining orthogonal planes was constructed with the use of the VoxelView and VoxelMath (Vital Images, Inc.) programs. Neuroanatomical structures were labeled in all three planes, providing the first labeled anatomical description of the spinner dolphin brain.

Genetics: The Not-So-New Thing, Dena S. Davis

Law Faculty Articles and Essays

Practical knowledge of heredity predates history. Indigenous peoples laid the foundations of modern agriculture by developing plants such as corn. However, the language and metaphors of the Human Genome Project treat modern genetics as if it had no historical antecedents and fail to acknowledge these early contributions to the science of heredity. The results of this blindness are twofold: it exacerbates reluctance of native peoples to take part in genetic research and to garner the benefits of genetic medicine, and it encourages "biopiracy," as modern scientists "discover" and patent native plants.

Relative Importance Of Heat-Labile Enterotoxin In The Causation Of Severe Diarrheal Disease In The Gnotobiotic Piglet Model By A Strain Of Enterotoxigenic Escherichia Coli That Produces Multiple Enterotoxins, Emil M. Berberov, You Zhou, David H. Francis, Michael A. Scott, Stephen D. Kachman, Rodney A. Moxley

School of Veterinary and Biomedical Sciences: Faculty Publications

Enterotoxigenic Escherichia coli (ETEC) strains that produce multiple enterotoxins are important causes of severe dehydrating diarrhea in human beings and animals, but the relative importance of these enterotoxins in the pathogenesis is poorly understood. Gnotobiotic piglets were used to study the importance of heat-labile enterotoxin (LT) in infection with an ETEC strain that produces multiple enterotoxins. LT^- (ΔeltAB) and complemented mutants of an F4⁺ LT⁺ STb⁺ EAST1⁺ ETEC strain were constructed, and the virulence of these strains was compared in gnotobiotic piglets expressing receptors for F4⁺ fimbria. Sixty percent of the piglets …

Politics Of Embryonic Discourse, Kevin Quinn

Faculty Publications

In our brave new world of stem cells, clones, and parthenotes, how should we talk about early human embryos? In fashioning a response to this very thorny question, Ann Kiessling has a core message. It is: (1)that new science produces "new" conceptuses;(2) that science and scientists have failed to differentiate (with appropriate clarity) these new ex vivo conceptuses from those createdin vivo; (3) that new, more appropriate and scientifically-informed, terms are necessary; and (4) that this new language should transform the public discourse about human embryos. No one would deny that the subtleties of human embryology are neglected in public …

Activation Of The Phosphatidylinositol 3-Kinase/Akt Pathway Contributes To Survival Of Primary Epithelial Cells Infected With The Periodontal Pathogen Porphyromonas Gingivalis, Özlem Yilmaz, Thomas Jungas, Philippe Verbeke, David M. Ojcius

All Dugoni School of Dentistry Faculty Articles

Porphyromonas gingivalis, an important periodontal pathogen, infects primary gingival epithelial cells (GECs). Despite the large number of bacteria that replicate inside the GECs, the host cell remains viable. We demonstrate that P. gingivalis triggers rapid and reversible surface phosphatidylserine exposure through a mechanism requiring caspase activation. However, after 1 day of infection, the bacteria no longer induce phosphatidylserine externalization and instead protect infected cells against apoptosis. Infection exerts its effect at the level of mitochondria, as P. gingivalis also blocks depolarization of the mitochondrial transmembrane potential and cytochrome c release. Interestingly, protein kinase B/Akt is phosphorylated during infection, which can …

Effects Of Ultrasonic And Hand-Activated Scaling On Tactile Sensitivity In Second Year Dental Hygiene Students In A Clinical Setting, Miranda Beeson

Dental Hygiene Theses & Dissertations

The purpose of this study was to determine if time spent instrumenting class III, IV, and V calculus clients, either hand-activated or with an ultrasonic scaler, decreased the tactile sensitivity of the clinician, and if change occurs in index finger, middle finger, and thumb tactile sensitivity prior to and following 45-minute scaling episodes. This study also afforded an opportunity to determine if tactile sensitivity changed in the same dental hygiene students over a one-year period of time by comparing data with that of a similar study conducted in the fall of 2002. Random assignment and a sample size of 25 …

Linking Session Focus To Treatment Outcome In Evidence-Based Treatments For Adolescent Substance Abuse, Aaron Hogue, Howard A. Liddle, Sarah Dauber, Jessica Samuolis

Psychology Faculty Publications

The relation between specific therapy techniques and treatment outcome was examined for 2 empirically supported treatments for adolescent substance abuse: individual cognitive–behavioral therapy and multidimensional family therapy. Participants were 51 inner-city, substance-abusing adolescents receiving outpatient psychotherapy within a larger randomized trial. One session per case was evaluated using a 17-item observational measure of model-specific techniques and therapeutic foci. Exploratory factor analysis identified 2 subscales, Adolescent Focus and Family Focus, with strong interrater reliability and internal consistency. Process–outcome analyses revealed that family focus, but not adolescent focus, predicted posttreatment improvement in drug use, externalizing symptoms, and internalizing symptoms within both study …

Extending In Vitro Conditioning In Aplysia To Analyze Operant And Classical Processes In The Same Preparation, Björn Brembs, Douglas A. Baxter, John H. Byrne

Faculty, Staff and Student Publications

Operant and classical conditioning are major processes shaping behavioral responses in all animals. Although the understanding of the mechanisms of classical conditioning has expanded significantly, the understanding of the mechanisms of operant conditioning is more limited. Recent developments in Aplysia are helping to narrow the gap in the level of understanding between operant and classical conditioning, and have raised the possibility of studying the neuronal processes underlying the interaction of operant and classical components in a relatively complex learning task. In the present study, we describe a first step toward realizing this goal, by developing a single in vitro preparation …

Sadb Is Required For The Transition From Reversible To Irreversible Attachment During Biofilm Formation By Pseudomonas Aeruginosa Pa14, Nicky C. Caiazza, George A. O'Toole

Dartmouth Scholarship

Current models of biofilm formation by Pseudomonas aeruginosa propose that (i) planktonic cells become surface associated in a monolayer, (ii) surface-associated cells form microcolonies by clonal growth and/or aggregation, (iii) microcolonies transition to a mature biofilm comprised of exopolysaccharide-encased macrocolonies, and (iv) cells exit the mature biofilm and reenter the planktonic state. Here we report a new class of P. aeruginosa biofilm mutant that defines the transition from reversible to irreversible attachment and is thus required for monolayer formation. The transposon insertion carried by the sadB199 mutant was mapped to open reading frame PA5346 of P. aeruginosa PA14 and encodes …

The Ultrastructure Of The Olfactory System In Two Species Of Short-Tailed Shrews, Blarina Brevicauda And Blarina Carolinensis, Lisa Johnson Byrum

Theses and Dissertations in Biomedical Sciences

Several studies of the fine structure of the olfactory system of rodents have been conducted, but very little research has been done on members of the Insectivora. The olfactory systems of the northern short-tailed shrew, Blarina brevicauda, and the southern short-tailed shrew, Blarina carolinensis, were examined by light and electron microscopy. These shrews were live trapped in the vicinity of Norfolk, Virginia throughout all months of the year. Olfactory tissues were processed following standard transmission and scanning electron microscopy protocols. The olfactory system structures investigated included the olfactory epitheliumlmucosa (OEM), main olfactory bulb (MOB), accessory olfactory bulb (AOB), …

Proceedings Of The National Workshop On Footrot, Perth 19-21 August 2003, R K. Mitchell, A R B Higgs, A R. Mercy
